Surprise, star scientists study the taxes they will pay & act accordingly choosing work location to help reducing them

The Effect of State Taxes on the Geographical Location of Top Earners: Evidence from Star Scientists. Enrico Moretti and Daniel J. Wilson. American Economic Review, vol. 107, no. 7, July 2017, (pp. 1858-1903). https://www.aeaweb.org/articles?id=10.1257/aer.20150508

Abstract: We quantify how sensitive is migration by star scientists to changes in personal and business tax differentials across states. We uncover large, stable, and precisely estimated effects of personal and corporate taxes on star scientists' migration patterns. The long-run elasticity of mobility relative to taxes is 1.8 for personal income taxes, 1.9 for state corporate income tax, and —1.7 for the investment tax credit. While there are many other factors that drive when innovative individuals and innovative companies decide to locate, there are enough firms and workers on the margin that state taxes matter.

Decline in US states' capital tax rates is due to synchronous responses to common shocks rather than competitive responses to other state's tax policy

Tax competition among U.S. states: Racing to the bottom or riding on a seesaw? Robert Chirinko and Daniel Wilson. Journal of Public Economics, Volume 155, November 2017, Pages 147-163. https://doi.org/10.1016/j.jpubeco.2017.10.001

Highlights
•    The reaction in a given U.S. state to capital tax changes in other states is analyzed.
•    The reaction function slope is negative, contrary to casual evidence and many prior studies.
•    Allowing for delayed reactions and heterogeneous responses to aggregate shocks is crucial.
•    Our empirical results suggest frequently-used static tax competition models are misspecified.
•    Rather than “racing to the bottom,” our findings suggest states are “riding on a seesaw”.


Abstract: Dramatic declines in capital tax rates among U.S. states and European countries have been linked by many commentators to tax competition, an inevitable "race to the bottom," and underprovision of local public goods. This paper analyzes the reaction of capital tax policy in a given U.S. state to changes in capital tax policy by other states. Our study is undertaken with a novel panel data set covering the 48 contiguous U.S. states for the period 1965 to 2006 and is guided by the theory of strategic tax competition. The latter suggests that capital tax policy is a function of "foreign" (out-of-state) tax policy, preferences for government services, home state and foreign state economic and demographic conditions. The slope of the reaction function - the equilibrium response of home state to foreign state tax policy - is negative, contrary to casual evidence and many prior empirical studies of fiscal reaction functions. This result, which stands in contrast to most published findings, is due to two critical elements that allow for delayed responses to foreign tax changes and responses to aggregate shocks. Omitting either of these elements leads to a misspecified model and a positively sloped reaction function. Our results suggest that the secular decline in capital tax rates, at least among U.S. states, reflects synchronous responses among states to common shocks rather than competitive responses to foreign state tax policy. While striking given prior empirical findings, these results are fully consistent with the implications of the theoretical model developed in this paper and presented elsewhere in the literature. Rather than "racing to the bottom," our findings suggest that states are "riding on a seesaw." Consequently, tax competition may lead to an increase in the provision of local public goods, and policies aimed at restricting tax competition to stem the tide of declining capital taxation are likely to be ineffective.

Desirability of Narcissism: The Young Find It More Appealing, Less Undesirable

Age Differences in the Desirability of Narcissism. Kathy R. Berenson, William D. Ellison, and Rachel Clasing. Journal of Individual Differences (2017), 38, pp. 230-240. https://doi.org/10.1027/1614-0001/a000240

Abstract. Young adult narcissism has been the focus of much discussion in the personality literature and popular press. Yet no previous studies have addressed whether there are age differences in the relative desirability of narcissistic and non-narcissistic self-descriptions, such as those presented as answer choices on the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979). In Study 1, younger age was associated with less negative evaluations of narcissistic (vs. non-narcissistic) statements in general, and more positive evaluations of narcissistic statements conveying leadership/authority. In Study 2, age was unrelated to perceiving a fictional target person as narcissistic, but younger age was associated with more positive connotations for targets described with narcissistic statements and less positive connotations for targets described with non-narcissistic statements, in terms of the inferences made about the target’s altruism, conscientiousness, social status, and self-esteem. In both studies, age differences in the relative desirability of narcissism remained statistically significant when adjusting for participants’ own narcissism, and the NPI showed measurement invariance across age. Despite perceiving narcissism similarly, adults of different ages view the desirability of NPI answer choices differently. These results are important when interpreting cross-generational differences in NPI scores, and can potentially facilitate cross-generational understanding.

Smartphone-tracking data & precinct-level voting data show that politically-divided families shortened Thanksgiving dinners by 20-30 minutes following the 2016 election

M. Keith Chen and Ryne Rohla. “Politics Gets Personal: Effects of Political Partisanship and Advertising on Family Ties.” 2017 (Under Review). https://economics.stanford.edu/sites/default/files/sharable_fulldraft.pdf

Abstract: Research on growing American political polarization and antipathy primarily studies effects on public institutions and political processes, ignoring private effects such as damaged family ties. Using smartphone-tracking data and precinct-level voting, we show that politically-divided families shortened Thanksgiving dinners by 20-30 minutes following the divisive 2016 election. This decline survives comparisons with 2015 and extensive demographic and spatial controls, and more than doubles in media markets with heavy political advertising. These effects appear asymmetric: while Democratic voters traveled less in 2016, political differences shortened Thanksgiving dinners more among Republican voters, especially where political advertising was heaviest. Partisan polarization may degrade close family ties with large aggregate implications; we estimate 27 million person-hours of cross-partisan Thanksgiving discourse were lost in 2016 to ad-fueled partisan effects.

One Sentence Summary: Cell-tracking shows that mixed-party families had shorter 2016 Thanksgivings, an effect exacerbated by political advertising.

The left part of the brain is crucial in the construction of novel representations by integrating memory content in new ways and supporting executively demanding mental simulations

To create or to recall original ideas: Brain processes associated with the imagination of novel object uses. Mathias Benedek et al. Cortex, https://doi.org/10.1016/j.cortex.2017.10.024

Abstract: This fMRI study investigated what brain processes contribute to the generation of new ideas. Brain activation was measured while participants generated new original object uses, recalled original object uses, or recalled common object uses. Post-scan evaluations were used to confirm what ideas were newly generated on the spot or actually retrieved from memory. When compared to the recall of common ideas, the generation of new and old original ideas showed a similar activation pattern including activation of bilateral parahippocampal and mPFC regions, suggesting that the construction of new ideas builds on similar processes like the reconstruction of original ideas from episodic memory. As a difference, the generation of new object uses involved higher activation of a focused cluster in the left supramarginal gyrus compared to the recall of original ideas. This finding adds to the converging evidence that the left supramarginal gyrus is crucially involved in the construction of novel representations, potentially by integrating memory content in new ways and supporting executively demanding mental simulations. This study deepens our understanding of how creative thought builds on and goes beyond memory.

The origins of social conservatism: an extended twin family study using self- and peer-reports

The origins of social conservatism: an extended twin family study using self- and peer-reports. Edward Bell et al. Behavior Genetics Association 47th Annual Meeting Abstracts (2017). https://doi.org/10.1007/s10519-017-9879-6

Abstract: It has long been recognized that social conservatism forms an important part of people’s political orientations. This study examines key genetic and environmental sources of individual differences in this trait, using data taken from a German sample that included twins, their parents, and their spouses, and which incorporated both self- and peer-reports. The extended twin family design we used allowed for the examination of various aspects of social conservatism, such as: the effects of assortative mating and passive genotype-environment correlation; shared environmental influences originating from mothers only, fathers only, and both together; and non-parental environmental effects shared by twins. A comparison of self-report with peer-report findings indicated that although sex and age differences in social conservatism were comparable across the two rater perspectives, model analyses based on self-reports yielded substantially higher estimates of heritability, as well as higher levels of shared parental environmental influences, assortative mating, and genotype-environment correlation. These results, in particular the higher levels of heritability derived from self-report data, have important implications for how we understand social conservatism.

Sexual insults are linked to narcissistic, non-compliant and misanthropic character, & to socially repugnant behavior like bullying & intimate partner violence

Hyatt, Courtland, Jessica L Maples-Keller, Chelsea Sleep, Donald Lynam, and Josh Miller. 2017. “The Anatomy of an Insult: Popular Derogatory Terms Connote Important Individual Differences in Externalizing Behavior”. PsyArXiv. November 7. psyarxiv.com/8nybx

Abstract: A large body of academic literature on personality has roots in the lexical hypothesis, the idea that the language contains information about the important individual differences among people. In the current series of studies, we investigate the psychosocial connotations of common insults, or terms used to derogate others. In Studies 1 and 2, we investigated the most frequently used insults to denigrate men and women (asshole, dick, bitch), and generated trait profiles that can be considered prototypical of each insult. In Studies 3 and 4, we expanded the scope of our investigation by examining how these insults are relevant to other key indicators of interpersonal functioning, including aggression, social information processing, personality disorders, and substance use. We also gathered thin-slice and informant reports to compare to self-reported insult endorsement. Each of the insults was strongly associated with trait Antagonism, as well as other behaviors that comprise Antagonism’s nomological network (e.g., bullying, psychopathy, social discounting, etc.) Additionally, informants and strangers tended to converge in their insult ratings. Results are discussed in terms of the importance of everyday language to psychological research.

We don't share political opinions with co-workers to avoid potential conflict, giving the impression of greater homogeneity and, paradoxically, more polarization

“It could turn ugly”: Selective disclosure of attitudes in political discussion networks. Sarah K.Cowan and Delia Baldassarri. Social Networks, Volume 52, January 2018, Pages 1-17. https://doi.org/10.1016/j.socnet.2017.04.002

Highlights
•    We study under which conditions people reveal their political views to their discussion partners.
•    Americans are more likely to share their opinions with friends and family rather than co-workers.
•    We document the mechanism of selective disclosure.
•    Individuals, to avoid conflict, withhold their political views from those with whom they disagree.
•    What consequences selective disclosure has on social influence and political polarization?

Abstract: This article documents individuals selectively disclosing their political attitudes and discusses the consequences of these communication patterns for social influence and the democratic process. Using a large, diverse sample of U.S. resident adults, we ask under which conditions do people reveal their political preferences versus keeping them close to the vest. We find Americans are more likely to share their opinions with friends and family rather than co-workers and they are more likely to share their opinions on more salient topics. More importantly, they withhold their political attitudes specifically from those with whom they disagree in an attempt to avoid conflict. This produces the experience of highly homogeneous social contexts, in which only liberal or conservative views are voiced, while dissent remains silent, and oftentimes goes unacknowledged. This experience is not the result of homogeneous social contexts but the appearance of them. Paradoxically, the mechanism of selective disclosure, whose goal is to prevent conflict at the micro-level, might lead to the perception of greater division in the larger society.

Criminal energetics: A theory of antisocial enhancement and criminal attenuation

Criminal energetics: A theory of antisocial enhancement and criminal attenuation. Michael G. Vaughn, Matt DeLisi. Aggression and Violent Behavior, https://doi.org/10.1016/j.avb.2017.11.002

Highlights
•    The role of energy in shaping antisocial and criminal careers is examined.
•    Energy is an enhancement and attenuator to an antisocial career.
•    A set of future research pathways for studying energetics and criminality is presented.

Abstract: Although energy is the currency of all life forms and energy is an underlying factor for physical and mental performance, its role in antisocial behavior has yet to be articulated. In this paper, we consider the role of energy in shaping antisocial and criminal careers and suggest that much like other forms of performance/productivity some criminal offenders are more energetic and therefore more virulent than others over the life-course. Specifically, we argue that energy is an enhancement and attenuator to an antisocial career and draw upon a diverse literature merging basic research on aging and energy production in human physiology and merge these findings with principles from the career criminal paradigm in criminology. Finally, we lay forth a set of research pathways, especially ways in which energy can be assessed, that can forge stronger links between the science of energetics and criminality.

Callousness and manipulativeness are central traits to a dark personality

A Network of Dark Personality Traits: What Lies at the Heart of Darkness? David K. Marcus, Jonathan Preszler, Virgil Zeigler-Hill. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2017.11.003

Highlights
•    Network analysis provides a novel approach to studying dark personality traits.
•    Interpersonal manipulation is central to a network of dark personality traits.
•    Callousness is central to a network of dark personality traits.

Abstract: The question of whether there is a common element at the core of the various dark personality traits (e.g., psychopathy, narcissism, Machiavellianism, spitefulness, aggressiveness) has been the subject of debate. Callousness, manipulativeness, and disagreeableness have all been nominated as possibly serving as the core of these dark traits. Network analysis, which graphically and quantitatively describes the centrality of various related traits, provides a novel technique for examining this issue. We estimated an association network and an Adaptive Least Absolute Shrinkage and Selection Operator network for two large samples, one college student sample (N = 2,831) and one mixed college student and Mechanical Turk sample (N = 844). Interpersonal manipulation and callousness were the traits that were central to the networks.

The “bad guy” profile is closer to the normal profile of real humans than that of the “good guys,” which are stereotyped

What are the cephalometric features of “good” and “bad” guys in cartoons? Alexandre Weiss, Cyril Villat, Alban Poitel and Sarah Gebeile-Chauty.  Orthod Fr, Volume 88, Issue 3, 263 - 274.
https://doi.org/10.1051/orthodfr/2017015

Abstract

Objective: The objective of the study was to search for links between specific facial features and the psychology of the “good” and “bad” guys in cartoons. Material and method: We made 60 cephalometric tracings and compared the characters’ profiles using statistical tests.

Results: The “bad guy” profile is closer to the normal profile of real humans than that of the “good guys”. Profiles perceived as “good” in cartoons appear to be stereotyped. Thus, any profile not matching the “norm” can be interpreted as being unpleasant and consequently associated with the features of the “bad guys”. The standard “bad guy” profile has a longer more prominent nose, a jutting chin (a bigger soft-tissue angle) and a higher upper third of the face than the lower third (the opposite of the standard profile of the “good guys”).

Discussion: These standardized portraits reflect and influence the (subconscious) prejudices of both young and less young movie-goers (not to mention the cartoonists) regarding their fellow humans.

Key words: Cephalometry / Profile / Soft tissue / Cartoon / Morphopsychology

Violence Against Women Journal: The Meaning and Practice of Ejaculation on a Woman’s Face

Naked Aggression: The Meaning and Practice of Ejaculation on a Woman’s Face. Chyng Sun, Matthew B. Ezzell, Olivia Kendall. Violence Against Women, Vol 23, Issue 14, 2017. https://doi.org/10.1177/1077801216666723

Abstract: Based on in-depth interviews with 16 heterosexual men, this study focuses on participants’ meaning-making surrounding a common and controversial sexual act in pornography: ejaculation on a woman’s face (EOWF). We analyze the ways that male consumers decoded EOWF and the ways that EOWF, as a sexual script, was included in the men’s accounts of their sexual desires and practices. The majority of the men decoded EOWF through the preferred (encoded) meaning as an act of male dominance and sexual aggression and that they wanted to engage in it despite their general belief that women would not be interested in it.

Keywords: pornography, sexual behaviors, sexual script, male aggression, audience research,

---
Given that U.S. society is White supremacist, patriarchal, and capitalist (hooks, 1994), it is not surprising that pornographers would encode these values in sexual expression and gender dynamics that may also be familiar and even attractive to male consumers. Put simply, pornography reflects the hegemonic value of male dominance and further perpetuates it. Just as rape is both illegal and normalized within patriarchal cultures (see, for example, Buchwald, Fletcher, & Roth, 2004), male dominance and sexual aggression in pornography may be found simultaneously distasteful and enticing. Some of the men in our study were open and direct about the appeal of EOWF as an expression of male dominance, but others couched the appeal of the act in its role in “pushing boundaries” or in its status as “taboo,” even if they could articulate the preferred meaning upon reflection. The strategy of euphemizing male sexual aggression as “taboo” may allow respondents to eroticize it without feeling misogynistic—but this strategy has its contradictions.

Indeed, multiple contradictions were revealed in the respondents’ discourses around pornography and sex. Typically, male participants initially failed to articulate why they liked to watch EOWF in pornography or what meaning they saw, if any, in the act. But when they were allowed some time to reflect, they stated that it is about male dominance and female degradation. Most men acknowledged that female porn stars come from economically disadvantaged backgrounds and would only perform EOWF for money, but they also maintained that some performers genuinely liked it—and they maintained that they could tell—while saying that they often engaged in a “suspension of disbelief” to convince themselves of the performers’ enjoyment. Respondents also stated that they did not think women around them would like to be the targets of EOWF; nonetheless, they desired or had performed the act. This group of men seemed to struggle with cognitive dissonance (Aronson, 1992; Festinger, 1957; Stalder & Baron, 1998) concerning pornography’s function of providing sexual pleasure (in private, while masturbating) and the misogynistic messages that they were made aware of through self-reflection (in public, with an interviewer). The respondents’ lack of critical reflection, or their holding multiple, contradictory perspectives without resolving them, may be a form of moral identity work that allows them to maintain their stated attitude of “respecting women” while finding pleasure in male dominance. It is particularly at this juncture—recognizing the misogyny of EOWF but finding excuses to keep watching or performing it—that we recognize the power of pornography both in its encoded messages and in the context in which it is used.

[...]

Given that the subjects in the study were highly educated and had access to discourses of feminism and gender equality, the finding is particularly sobering.

Richard Feynman on Why Questions

[Transcript] Richard Feynman on Why Questions
61 Post author: Grognor 08 January 2012 07:01PM
 
I thought this video was a really good question dissolving by Richard Feynman. But it's in 240p! Nobody likes watching 240p videos. So I transcribed it. (Edit: That was in jest. The real reasons are because I thought I could get more exposure this way, and because a lot of people appreciate transcripts. Also, Paul Graham speculates that the written word is universally superior than the spoken word for the purpose of ideas.) I was going to post it as a rationality quote, but the transcript was sufficiently long that I think it warrants a discussion post instead.

Here you go:
Interviewer: If you get hold of two magnets, and you push them, you can feel this pushing between them. Turn them around the other way, and they slam together. Now, what is it, the feeling between those two magnets?
Feynman: What do you mean, "What's the feeling between the two magnets?"
Interviewer: There's something there, isn't there? The sensation is that there's something there when you push these two magnets together.
Feynman: Listen to my question. What is the meaning when you say that there's a feeling? Of course you feel it. Now what do you want to know?
Interviewer: What I want to know is what's going on between these two bits of metal?
Feynman: They repel each other.
Interviewer: What does that mean, or why are they doing that, or how are they doing that? I think that's a perfectly reasonable question.
Feynman: Of course, it's an excellent question. But the problem, you see, when you ask why something happens, how does a person answer why something happens? For example, Aunt Minnie is in the hospital. Why? Because she went out, slipped on the ice, and broke her hip. That satisfies people. It satisfies, but it wouldn't satisfy someone who came from another planet and who knew nothing about why when you break your hip do you go to the hospital. How do you get to the hospital when the hip is broken? Well, because her husband, seeing that her hip was broken, called the hospital up and sent somebody to get her. All that is understood by people. And when you explain a why, you have to be in some framework that you allow something to be true. Otherwise, you're perpetually asking why. Why did the husband call up the hospital? Because the husband is interested in his wife's welfare. Not always, some husbands aren't interested in their wives' welfare when they're drunk, and they're angry.
And you begin to get a very interesting understanding of the world and all its complications. If you try to follow anything up, you go deeper and deeper in various directions. For example, if you go, "Why did she slip on the ice?" Well, ice is slippery. Everybody knows that, no problem. But you ask why is ice slippery? That's kinda curious. Ice is extremely slippery. It's very interesting. You say, how does it work? You could either say, "I'm satisfied that you've answered me. Ice is slippery; that explains it," or you could go on and say, "Why is ice slippery?" and then you're involved with something, because there aren't many things as slippery as ice. It's very hard to get greasy stuff, but that's sort of wet and slimy. But a solid that's so slippery? Because it is, in the case of ice, when you stand on it (they say) momentarily the pressure melts the ice a little bit so you get a sort of instantaneous water surface on which you're slipping. Why on ice and not on other things? Because water expands when it freezes, so the pressure tries to undo the expansion and melts it. It's capable of melting, but other substances get cracked when they're freezing, and when you push them they're satisfied to be solid.
Why does water expand when it freezes and other substances don't? I'm not answering your question, but I'm telling you how difficult the why question is. You have to know what it is that you're permitted to understand and allow to be understood and known, and what it is you're not. You'll notice, in this example, that the more I ask why, the deeper a thing is, the more interesting it gets. We could even go further and say, "Why did she fall down when she slipped?" It has to do with gravity, involves all the planets and everything else. Nevermind! It goes on and on. And when you're asked, for example, why two magnets repel, there are many different levels. It depends on whether you're a student of physics, or an ordinary person who doesn't know anything. If you're somebody who doesn't know anything at all about it, all I can say is the magnetic force makes them repel, and that you're feeling that force.
You say, "That's very strange, because I don't feel kind of force like that in other circumstances." When you turn them the other way, they attract. There's a very analogous force, electrical force, which is the same kind of a question, that's also very weird. But you're not at all disturbed by the fact that when you put your hand on a chair, it pushes you back. But we found out by looking at it that that's the same force, as a matter of fact (an electrical force, not magnetic exactly, in that case). But it's the same electric repulsions that are involved in keeping your finger away from the chair because it's electrical forces in minor and microscopic details. There's other forces involved, connected to electrical forces. It turns out that the magnetic and electrical force with which I wish to explain this repulsion in the first place is what ultimately is the deeper thing that we have to start with to explain many other things that everybody would just accept. You know you can't put your hand through the chair; that's taken for granted. But that you can't put your hand through the chair, when looked at more closely, why, involves the same repulsive forces that appear in magnets. The situation you then have to explain is why, in magnets, it goes over a bigger distance than ordinarily. There it has to do with the fact that in iron all the electrons are spinning in the same direction, they all get lined up, and they magnify the effect of the force 'til it's large enough, at a distance, that you can feel it. But it's a force which is present all the time and very common and is a basic force of almost - I mean, I could go a little further back if I went more technical - but on an early level I've just got to tell you that's going to be one of the things you'll just have to take as an element of the world: the existence of magnetic repulsion, or electrical attraction, magnetic attraction.
I can't explain that attraction in terms of anything else that's familiar to you. For example, if we said the magnets attract like if rubber bands, I would be cheating you. Because they're not connected by rubber bands. I'd soon be in trouble. And secondly, if you were curious enough, you'd ask me why rubber bands tend to pull back together again, and I would end up explaining that in terms of electrical forces, which are the very things that I'm trying to use the rubber bands to explain. So I have cheated very badly, you see. So I am not going to be able to give you an answer to why magnets attract each other except to tell you that they do. And to tell you that that's one of the elements in the world - there are electrical forces, magnetic forces, gravitational forces, and others, and those are some of the parts. If you were a student, I could go further. I could tell you that the magnetic forces are related to the electrical forces very intimately, that the relationship between the gravity forces and electrical forces remains unknown, and so on. But I really can't do a good job, any job, of explaining magnetic force in terms of something else you're more familiar with, because I don't understand it in terms of anything else that you're more familiar with.

Liking what others “Like”: using Facebook to identify determinants of conformity

Liking what others “Like”: using Facebook to identify determinants of conformity. Johan Egebark and Mathias Ekström. Experimental Economics, https://link.springer.com/article/10.1007/s10683-017-9552-1

Abstract: In this paper we explore the micro-level determinants of conformity. Members of the social networking service Facebook express positive support to content on the website by clicking a Like button. We set up a natural field experiment to test whether users are more prone to support content if someone else has done so before. To find out to what extent conformity depends on group size and social ties we use three different treatment conditions: (1) one stranger has Liked the content, (2) three strangers have Liked the content, and (3) a friend has Liked the content. The results show that one Like from a single stranger had no impact. However, increasing the size of the influencing group doubled the probability that subjects expressed positive support. Friendship ties were also decisive. People were, on average, four times more likely to press the Like button if a friend, rather than a stranger, had done so before them. The existence of threshold effects in our experiment clearly shows that both group size and social proximity matters when opinions are shaped.

Sexual Appeal Is In The Nose -- Patterns of Eye Movements When Observers Judge Female Facial Attractiveness

Patterns of Eye Movements When Observers Judge Female Facial Attractiveness. Yan Zhang et al. Front. Psychol., https://doi.org/10.3389/fpsyg.2017.01909

Abstract: The purpose of the present study is to explore the fixed model for the explicit judgments of attractiveness and infer which features are important to judge the facial attractiveness. Behavioral studies on the perceptual cues for female facial attractiveness implied three potentially important features: averageness, symmetry, and sexual dimorphy. However, these studies did not explained which regions of facial images influence the judgments of attractiveness. Therefore, the present research recorded the eye movements of 24 male participants and 19 female participants as they rated a series of 30 photographs of female facial attractiveness. Results demonstrated the following: (1) Fixation is longer and more frequent on the noses of female faces than on their eyes and mouths (no difference exists between the eyes and the mouth); (2) The average pupil diameter at the nose region is bigger than that at the eyes and mouth (no difference exists between the eyes and the mouth); (3) the number of fixations of male participants was significantly more than female participants. (4) Observers first fixate on the eyes and mouth (no difference exists between the eyes and the mouth) before fixating on the nose area. In general, participants attend predominantly to the nose to form attractiveness judgments. The results of this study add a new dimension to the existing literature on judgment of facial attractiveness. The major contribution of the present study is the finding that the area of the nose is vital in the judgment of facial attractiveness. This finding establish a contribution of partial processing on female facial attractiveness judgments during eye-tracking.
