Simpler grammar, larger vocabulary: How population size affects language. Florencia Reali, Nick Chater, Morten H. Christiansen. Proceedings of the Royal Society B, DOI: 10.1098/rspb.2017.2586
Abstract: Languages with many speakers tend to be structurally simple while small communities sometimes develop languages with great structural complexity. Paradoxically, the opposite pattern appears to be observed for non-structural properties of language such as vocabulary size. These apparently opposite patterns pose a challenge for theories of language change and evolution. We use computational simulations to show that this inverse pattern can depend on a single factor: ease of diffusion through the population. A population of interacting agents was arranged on a network, passing linguistic conventions to one another along network links. Agents can invent new conventions, or replicate conventions that they have previously generated themselves or learned from other agents. Linguistic conventions are either Easy or Hard to diffuse, depending on how many times an agent needs to encounter a convention to learn it. In large groups, only linguistic conventions that are easy to learn, such as words, tend to proliferate, whereas small groups where everyone talks to everyone else allow for more complex conventions, like grammatical regularities, to be maintained. Our simulations thus suggest that language, and possibly other aspects of culture, may become simpler at the structural level as our world becomes increasingly interconnected.

Warm and touching tears: tearful individuals are perceived as warmer because we assume they feel moved and touched
Warm and touching tears: tearful individuals are perceived as warmer because we assume they feel moved and touched. Janis H. Zickfeld & Thomas W. Schubert. Cognition and Emotion, https://doi.org/10.1080/02699931.2018.1430556
ABSTRACT: Recent work investigated the inter-individual functions of emotional tears in depth. In one study (Van de Ven, N., Meijs, M. H. J., & Vingerhoets, A. (2017). What emotional tears convey: Tearful individuals are seen as warmer, but also as less competent. British Journal of Social Psychology, 56(1), 146–160. Https://doi.org/10.1111/bjso.12162) tearful individuals were rated as warmer, and participants expressed more intentions to approach and help such individuals. Simultaneously, tearful individuals were rated as less competent, and participants expressed less intention to work with the depicted targets. While tearful individuals were perceived as sadder, perceived sadness mediated only the effect on competence, but not on warmth. We argue that tearful individuals might be perceived as warm because they are perceived as feeling moved and touched. We ran a pre-registered extended replication of Van de Ven et al. Results replicate the warmth and helping findings, but not the competence and work effects. The increase in warmth ratings was completely mediated by perceiving feeling moved and touched. Possible functions of feeling moved and touched with regard to emotional tears are discussed.

Do the Right Thing: Experimental evidence that preferences for moral behavior, rather than equity or efficiency per se, drive human prosociality
Do the Right Thing: Experimental evidence that preferences for moral behavior, rather than equity or efficiency per se, drive human prosociality. Valerio Capraro, David G. Rand. Judgment and Decision Making, Vol. 13, No. 1, January 2018, pp. 99-111. http://journal.sjdm.org/17/171107/jdm171107.html
Abstract: Decades of experimental research show that some people forgo personal gains to benefit others in unilateral anonymous interactions. To explain these results, behavioral economists typically assume that people have social preferences for minimizing inequality and/or maximizing efficiency (social welfare). Here we present data that cannot be explained by these standard social preference models. We use a “Trade-Off Game” (TOG), where players unilaterally choose between an equitable option and an efficient option. We show that simply changing the labelling of the options to describe the equitable versus efficient option as morally right completely reverses the correlation between behavior in the TOG and play in a separate Dictator Game (DG) or Prisoner’s Dilemma (PD): people who take the action framed as moral in the TOG, be it equitable or efficient, are much more prosocial in the DG and PD. Rather than preferences for equity and/or efficiency per se, our results suggest that prosociality in games such as the DG and PD are driven by a generalized morality preference that motivates people to do what they think is morally right.

Higher status people derogate ideological opponents less (i.e., evaluate them more charitably); greater rhetoric handling prowess (RHP: feeling more confident and less intimidated while arguing) mediates the effect
Aiden P. Gregg, Nikhila Mahadevan, and Constantine Sedikides (2018). Taking the High Ground: The Impact of Social Status on the Derogation of Ideological Opponents. Social Cognition: Vol. 36, Special Issue: The Status of Status: Vistas from Social Cognition, pp. 43-77. https://doi.org/10.1521/soco.2018.36.1.43
Abstract: People tend to derogate their ideological opponents. But how does social status affect this tendency? We tested a prediction derived from hierometer theory that people with higher status would derogate ideological opponents less (i.e., evaluate them more charitably). We further predicted that greater rhetoric handling prowess (RHP: feeling more confident and less intimidated while arguing) would mediate the effect. Study 1 established a link between higher status and lesser opponent derogation correlationally. Study 2 did so experimentally. Using a scale to assess RHP developed and validated in Study 3, Study 4 established that RHP statistically mediated the correlational link between status and derogation. In Study 5, experimentally manipulating status affected RHP as predicted. However, in Study 6, experimentally manipulating RHP did not affect opponent derogation as predicted. Thus, our findings were substantially, but not entirely, consistent with our theoretically derived predictions. Implications for hierometer theory, and related theoretical approaches, are considered.

For the poor, thoughts about cost and money are triggered by mundane circumstances, they are difficult to suppress, they change mental associations, and they interfere with other experiences

Abstract: Recent research has studied how resource scarcity draws attention and creates cognitive load. As a result, scarcity improves some dimensions of cognitive function, while worsening others. Still, there remains a fundamental question: how does scarcity influence the content of cognition? In this article, we find that poor individuals (i.e., those facing monetary scarcity) see many everyday experiences through a different lens. Specifically, thoughts about cost and money are triggered by mundane circumstances, they are difficult to suppress, they change mental associations, and they interfere with other experiences. We suggest that the poor see an economic dimension to many everyday experiences that to others may not appear economic at all.

Androstadienone, a Chemosignal Found in Human Sweat, Increases Individualistic Behavior and Decreases Cooperative Responses in Men
Androstadienone, a Chemosignal Found in Human Sweat, Increases Individualistic Behavior and Decreases Cooperative Responses in Men. A Banner, I Frumin, S G Shamay-Tsoory. Chemical Senses, bjy002, https://doi.org/10.1093/chemse/bjy002
Abstract: A growing body of evidence suggests that humans can communicate socially relevant information, such as aggression, dominance and readiness for competition, through chemosensory signals. Androstadienone (androsta-4,16,-dien-3-one), a testosterone-derived compound found in men's axillary sweat, is a main candidate for a human pheromone that may convey such information. The current study aimed to investigate whether androstadienone serves as a chemosignaling threat cue to men, thus triggering avoidance behavior during competitive interaction with another man. In a double-blind, placebo-controlled, within-subject study design, 30 healthy, normosmic, heterosexual male participants completed the Social Orientation Paradigm (SOP), a monetary game played against a fictitious partner that allows three types of responses to be measured in the context of provocation: an aggressive response, an individualistic withdrawal response, and a cooperative response. Participants completed the SOP task twice, once under exposure to androstadienone and once under exposure to a control solution. The results indicate that androstadienone increased individualistic responses while it decreased cooperative responses. These findings support the role of androstadienone as a threatening signal of dominance that elicits behavioral avoidance and social withdrawal tendencies, possibly as a submissive response.

The echo chamber is overstated: the moderating effect of political interest and diverse media
The echo chamber is overstated: the moderating effect of political interest and diverse media. Elizabeth Dubois & Grant Blank. Information, Communication & Society, https://doi.org/10.1080/1369118X.2018.1428656
ABSTRACT: In a high-choice media environment, there are fears that individuals will select media and content that reinforce their existing beliefs and lead to segregation based on interest and/or partisanship. This could lead to partisan echo chambers among those who are politically interested and could contribute to a growing gap in knowledge between those who are politically interested and those who are not. However, the high-choice environment also allows individuals, including those who are politically interested, to consume a wide variety of media, which could lead them to more diverse content and perspectives. This study examines the relationship between political interest as well as media diversity and being caught in an echo chamber (measured by five different variables). Using a nationally representative survey of adult internet users in the United Kingdom (N = 2000), we find that those who are interested in politics and those with diverse media diets tend to avoid echo chambers. This work challenges the impact of echo chambers and tempers fears of partisan segregation since only a small segment of the population are likely to find themselves in an echo chamber. We argue that single media studies and studies which use narrow definitions and measurements of being in an echo chamber are flawed because they do not test the theory in the realistic context of a multiple media environment.

There is a small positive relation between service quality and percentage of a bill tipped; service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size
Banks, G. C., Woznyj, H. M., Kepes, S., Batchelor, J. H. and McDaniel, M. A. (), A meta-analytic review of tipping compensation practices: An agency theory perspective. Personnel Psychology. Accepted Author Manuscript. doi:10.1111/peps.12261
Tipping represents a form of compensation valued at over $50 billion a year in the U.S. alone. Tipping can be used as an incentive mechanism to reduce a principal-agent problem. An agency problem occurs when the interests of a principal and agent are misaligned and it is challenging for the principal to monitor or control the activities of the agent. However, past research has been limited in the investigation of the extent to which tipping is effective at addressing this problem. Following an examination of 74 independent studies with 12,271 individuals, meta-analytic results indicate that there is a small, positive relation between service quality and percentage of a bill tipped (rho =.15 without outliers). Yet, in support of the idea behind tipping, relative weights analyses illustrate that service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size. Evidence also suggests that racial minority servers tend to be tipped less than White servers (Cohen's d = .17), and females tend to be tipped more than males (Cohen's d = .15). Still, given the magnitude of the effect, one might question if tipping is an effective compensation practice to reduce the principal-agent problem. We discuss theoretical and practical implications for future research.

Only Bad for Believers? Religion, Pornography Use, and Sexual Satisfaction Among American Men
Only Bad for Believers? Religion, Pornography Use, and Sexual Satisfaction Among American Men. Perry, Samuel L., Whitehead, Andrew L. The Journal of Sex Research, https://doi.org/10.1080/00224499.2017.1423017
Abstract: Research has often demonstrated a negative association between pornography use and various intrapersonal and relationship outcomes, particularly for men. Several recent studies, however, have suggested that the negative association between pornography use and these indicators is stronger among more religious Americans, suggesting that moral incongruence (engaging in an activity that violates one’s sacred values) and the attendant shame or cognitive dissonance, rather than pornography use per se, may be the primary factor at work. The current study tested and extended this theory by examining how religion potentially moderates the link between pornography use and sexual satisfaction in a national random sample of American adults (N = 1,501). Analyses demonstrated that while pornography use was negatively associated with sexual satisfaction for American men (not women), among men who rarely attended religious services or held a low opinion of the Bible this negative association essentially disappeared. Conversely, the negative association between frequency of pornography consumption and sexual satisfaction was more pronounced for men with stronger ties to conventional religion. These findings suggest that the connection between pornography use and sexual satisfaction, especially for men, depends largely on what viewing pornography means to consumers and their moral community and less so on the practice itself.

Offspring sex ratio: Coital rates and other potential causal mechanisms
Offspring sex ratio: Coital rates and other potential causal mechanisms. William H.James, VictorGrech. Early Human Development, Volume 116, January 2018, Pages 24-27. https://doi.org/10.1016/j.earlhumdev.2017.10.006
Highlights
• Sex ratios at birth (SRB) are elevated by increased coital rates.
• Maternal stress induces male foetal losses.
• Periconceptual parental hormone concentrations may influence SRB.
• Understanding SRB influences may help understand causes of diseases with unusual SRB.
• E.g.: testicular cancer, hepatitis B, Toxoplasma gondii and, perhaps, prostatic cancer
Abstract: In recent years, scientists have begun to pay serious attention to the hypothesis that human parental coital rates around the time of conception causally influences the sexes of subsequent births. In this paper, the grounds of the argument are outlined. The point is important because, if the hypothesis were credible, it can potentially explain one of the best established (and otherwise unexplained) epidemiological features of sex ratio at birth – its rises during and just after World Wars 1 and 2 insofar as increased coital rates increase the ratio. Moreover, the greater the understanding of the variations of sex ratio at birth, the greater will be the understanding of the causes of those selected diseases associated with unusual sex ratios at birth (testicular cancer, hepatitis B, Toxoplasma gondii, and, perhaps, prostatic cancer).

Our primary result is that collective bargaining rights lead to about a 27% increase in complaints of officer misconduct for the typical sheriff’s office

University of Chicago Coase-Sandor Institute for Law & Economics Research Paper No. 831; U of Chicago, Public Law Working Paper No. 655. Available at SSRN: https://ssrn.com/abstract=3095217
Abstract: Growing controversy surrounds the impact of labor unions on law enforcement behavior. Critics allege that unions impede organizational reform and insulate officers from discipline for misconduct. The only evidence of these effects, however, is anecdotal. We exploit a quasi-experiment in Florida to estimate the effects of collective bargaining rights on law enforcement misconduct and other outcomes of public concern. In 2003, the Florida Supreme Court’s Williams decision extended to county deputy sheriffs collective bargaining rights that municipal police officers had possessed for decades. We construct a comprehensive panel dataset of Florida law enforcement agencies starting in 1997, and employ a difference-in-difference approach that compares sheriffs’ offices and police departments before and after Williams. Our primary result is that collective bargaining rights lead to about a 27% increase in complaints of officer misconduct for the typical sheriff’s office. This result is robust to the inclusion of a variety of controls. The time pattern of the estimated effect, along with an analysis using agency-specific trends, suggests that it is not attributable to preexisting trends. The estimated effect of Williams is not robustly significant for other potential outcomes of interest, however, including the racial and gender composition of agencies and training and educational requirements.

The effects of social priming, the voodoo theory of social psychology, manifested themselves only when the experiments weren't double blinded, exposing a self-fulfilling prophecy
The Role of Experimenter Belief in Social Priming. Thandiwe S. E. Gilder, Erin A. Heerey. Psychological Science, https://doi.org/10.1177/0956797617737128
Abstract: Research suggests that stimuli that prime social concepts can fundamentally alter people’s behavior. However, most researchers who conduct priming studies fail to explicitly report double-blind procedures. Because experimenter expectations may influence participant behavior, we asked whether a short pre-experiment interaction between participants and experimenters would contribute to priming effects when experimenters were not blind to participant condition. An initial double-blind experiment failed to demonstrate the expected effects of a social prime on executive cognition. To determine whether double-blind procedures caused this result, we independently manipulated participants’ exposure to a prime and experimenters’ belief about which prime participants received. Across four experiments, we found that experimenter belief, rather than prime condition, altered participant behavior. Experimenter belief also altered participants’ perceptions of their experimenter, suggesting that differences in experimenter behavior across conditions caused the effect. Findings reinforce double-blind designs as experimental best practice and suggest that people’s prior beliefs have important consequences for shaping behavior with an interaction partner.

Participants reported feeling younger than they actually were and wanting to be younger than their chronological age
Subjective Age and Its Correlates Among Middle-Aged and Older Adults. Shiri Shinan-Altman, Perla Werner. The International Journal of Aging and Human Development, https://doi.org/10.1177/0091415017752941
Abstract: The present study evaluates discrepancies in subjective age as reported by middle-age persons (aged 44–64 years) in comparison to older adults (aged 65 years and older), using a multidimensional definition of the concept. A convenience sample of 126 middle-aged and 126 older adults completed subjective age measures (felt age, desired age, and perceived old age), attitudes toward older adults, knowledge about aging, and sociodemographic questionnaires. Overall, participants reported feeling younger than they actually were and wanting to be younger than their chronological age. Perceived mean for old age was about 69 years. Discrepancies in felt age and desired age were significantly larger for the older group compared to the middle-aged group. Regarding perceived old age, compared to the younger group, older adults reported that old age begins at an older age. Findings suggest that middle-aged and older adults’ perceptions regarding themselves and regarding old age in general are independent and need, therefore, separate research and practical attention.

Men’s and Women’s Youngest and Oldest Considered and Actual Sex Partners
Antfolk, Jan, 2018. “Men’s and Women’s Youngest and Oldest Considered and Actual Sex Partners”. PsyArXiv. January 29. doi:10.1177/1474704917690401
Abstract: Whereas women prefer slightly older sexual partners, men—regardless of their age—have a preference for women in their twenties. Earlier research has suggested that this difference between the sexes’ age preferences is resolved according to women’s preferences. Earlier research has not, however, sufficiently considered that the age-range of considered partners might change over the life span. Here, we investigated the age limits (youngest and oldest) of considered and actual sex partners in a population-based sample of 2,655 adults (aged 18-50 years). Over the investigated age span, women reported a narrower age-range than men and women tended to prefer slightly older men. We also show that men’s age-range widens as they get older: While they continue to consider sex with young women, men also consider sex with women their own age or older. Contrary to earlier suggestions, men’s sexual activity thus reflects also their own age-range, although their potential interest in younger women is not likely converted into sexual activity. Compared to homosexual men, bisexual and heterosexual men were more unlikely to convert young preferences into actual behavior, supporting female-choice theory.
Abstract: Whereas women prefer slightly older sexual partners, men—regardless of their age—have a preference for women in their twenties. Earlier research has suggested that this difference between the sexes’ age preferences is resolved according to women’s preferences. Earlier research has not, however, sufficiently considered that the age-range of considered partners might change over the life span. Here, we investigated the age limits (youngest and oldest) of considered and actual sex partners in a population-based sample of 2,655 adults (aged 18-50 years). Over the investigated age span, women reported a narrower age-range than men and women tended to prefer slightly older men. We also show that men’s age-range widens as they get older: While they continue to consider sex with young women, men also consider sex with women their own age or older. Contrary to earlier suggestions, men’s sexual activity thus reflects also their own age-range, although their potential interest in younger women is not likely converted into sexual activity. Compared to homosexual men, bisexual and heterosexual men were more unlikely to convert young preferences into actual behavior, supporting female-choice theory.
Participants liked targets less, were less romantically interested in targets, and rated targets as less attractive after discovering political dissimilarity with them
Mallinas, Stephanie, Jarret Crawford, and Shana Cole 2018. “Political Opposites Do Not Attract: The Effects of Ideological Dissimilarity on Impression Formation”. PsyArXiv. January 29. psyarxiv.com/p3j8v
Abstract: Past research shows that people like others who are similar to themselves, and that political partisans tend to dislike those with opposing viewpoints. Two studies examined how initial person impressions changed after discovering that the target held similar or dissimilar political beliefs. Using potential mates as targets, we found that participants liked targets less, were less romantically interested in targets, and rated targets as less attractive after discovering political dissimilarity with them. Further, they became more uncomfortable with targets after discovering ideological dissimilarity. Theoretical implications and suggestions for future research are discussed.
