No evidence to support an association between emotion recognition deficits and previous exposure to adversity, either in terms of total lifetime exposure, timing, duration, or recency, or when stratifying by sex

Dunn, E. C., Crawford, K. M., Soare, T. W., Button, K. S., Raffeld, M. R., Smith, A. D.A.C., Penton-Voak, I. S. and Munafò, M. R. (2018), Exposure to childhood adversity and deficits in emotion recognition: results from a large, population-based sample. J Child Psychol Psychiatr. doi:10.1111/jcpp.12881

Abstract

Background: Emotion recognition skills are essential for social communication. Deficits in these skills have been implicated in mental disorders. Prior studies of clinical and high-risk samples have consistently shown that children exposed to adversity are more likely than their unexposed peers to have emotion recognition skills deficits. However, only one population-based study has examined this association.

Methods: We analyzed data from children participating in the Avon Longitudinal Study of Parents and Children, a prospective birth cohort (n = 6,506). We examined the association between eight adversities, assessed repeatedly from birth to age 8 (caregiver physical or emotional abuse; sexual or physical abuse; maternal psychopathology; one adult in the household; family instability; financial stress; parent legal problems; neighborhood disadvantage) and the ability to recognize facial displays of emotion measured using the faces subtest of the Diagnostic Assessment of Non-Verbal Accuracy (DANVA) at age 8.5 years. In addition to examining the role of exposure (vs. nonexposure) to each type of adversity, we also evaluated the role of the timing, duration, and recency of each adversity using a Least Angle Regression variable selection procedure.

Results: Over three-quarters of the sample experienced at least one adversity. We found no evidence to support an association between emotion recognition deficits and previous exposure to adversity, either in terms of total lifetime exposure, timing, duration, or recency, or when stratifying by sex.

Conclusions: Results from the largest population-based sample suggest that even extreme forms of adversity are unrelated to emotion recognition deficits as measured by the DANVA, suggesting the possible immutability of emotion recognition in the general population. These findings emphasize the importance of population-based studies to generate generalizable results.

Married...with children: The science of well-being in marriage and family life

Nelson-Coffey, S. K. (2018). Married...with children: The science of well-being in marriage and family life.  In E. Diener, S. Oishi, & L. Tay (Eds.),  Handbook of well-being. Salt Lake City, UT: DEF Publishers. DOI:nobascholar.com.

Abstract: As  some  of  the  most  important  relationships  in  people’s  lives,  marriage  and  parenthood  offer  many opportunities  for  people  to  experience  great  joy  or  to suffer  incredible  disappointment.  In  the  current chapter, I review current understanding of whether, how, and why marriage and parenthood are associated with well-being, drawing on evidence from cross-sectional, longitudinal, and daily experience studies. I also consider the implications of family structure for the associations between marriage and well-being, and parenthood  and  well-being,  respectively.  Current evidence  provides  relatively  robust  support  for  the association between marriage and well-being; however, the association between parenthood is much more complex. I conclude with a number of suggestions for future research.

Significant variation in suicide frequency concerning day of the week with a peak on Mondays and Tuesdays and seasonality with increased numbers in spring and summer months

Time-related aspects of suicides – suicide frequency related to birthday, major holidays, day of the week, season, month of birth and zodiac signs. Eberhard A. Deisenhammer, Christoph Stiglbauer, Georg Kemmler. Neuropsychiatrie, https://link.springer.com/article/10.1007/s40211-018-0260-7

Summary

Background: Suicides are generally the consequence of overchallenged coping strategies of individual for psychological, social or internal and external biological strain factors. Timing of the suicide, too, may be influenced by external factors. Studies so far have yielded in part inconsistent results concerning the association of suicides with particular days or periods of the year. Even less is known regarding a potential effect of the time of birth on suicide risk.

Methods: The Tyrol Suicide Register (TSR) provides data on suicides occurring in the Austrian State of Tyrol including birthday of the suicide victim and day of the suicide. In the present study the frequency of suicides was analyzed with regard to birthday, day of the week, major holidays and season over a period of 17 years. Further, a potential association with month of birth and zodiac signs was studied.

Results: We found a significant variation in suicide frequency concerning day of the week with a peak on Mondays and Tuesdays and seasonality with increased numbers in spring and summer months.

Conclusions: The increase of suicide numbers at the beginning of the week may be explained by the “broken-promise effect” which has been described as the consequence of frustrated expectations concerning the weekend. Possible explanations for the suicide peaks in spring and summer may be biological, specifically serotonergic alterations as well as the experience of depressed patients perceiving the social and emotional contrast to people who are able to enjoy these periods of pleasure and outdoor activities.

Relatedness decreases and reciprocity increases cooperation in Norway rats

Relatedness decreases and reciprocity increases cooperation in Norway rats. Manon K. Schweinfurth, Michael Taborsky. Proceedings of the Royal Society B, March 07 2018.DOI: 10.1098/rspb.2018.0035

Abstract: Kin selection and reciprocity are two mechanisms underlying the evolution of cooperation, but the relative importance of kinship and reciprocity for decisions to cooperate are yet unclear for most cases of cooperation. Here, we experimentally tested the relative importance of relatedness and received cooperation for decisions to help a conspecific in wild-type Norway rats (Rattus norvegicus). Test rats provided more food to non-kin than to siblings, and they generally donated more food to previously helpful social partners than to those that had refused help. The rats thus applied reciprocal cooperation rules irrespective of relatedness, highlighting the importance of reciprocal help for cooperative interactions among both related and unrelated conspecifics.

Decision-makers are resilient in the face of social exclusion

Juanchich, M., Walasek, L. and Sirota, M. (2018), Decision-makers are resilient in the face of social exclusion. Br J Psychol. doi:10.1111/bjop.12294

Abstract: A growing body of evidence suggests that social exclusion impairs people's capacity for active deliberation and logical reasoning. Building on this finding and on the postulate from the dual-process theory that analytical thinking is essential in order to make good judgements and decisions, we hypothesized that social exclusion will alter judgement and choice behaviour. We tested this hypothesis in three experiments in which social exclusion was manipulated using the Cyberball paradigm, an online ball-tossing game in which participants either received the ball a fair number of times or were excluded by the other two players. We focused on a range of tasks designed to be sensitive to participants’ ability to engage in analytical thinking and careful deliberation, including the cognitive reflection test (Experiment 1) and a set of anchoring, intertemporal preference, disjunction, and confidence tasks (experiments 2 and 3). Our results unanimously failed to support the hypothesis that social exclusion influences people's judgements and decision-making. We discuss the implications of our findings for social exclusion theory.

Our results also showed that Facebook news use was related to a modest over-time spiral of depolarization. Furthermore, we found that people who use Facebook for news were more likely to view both pro- and counter-attitudinal news in each wave

Facebook news and (de)polarization: reinforcing spirals in the 2016 US election. Michael A. Beam, Myiah J. Hutchens & Jay D. Hmielowski. Information, Communication & Society,  https://doi.org/10.1080/1369118X.2018.1444783

ABSTRACT: The rise of social media, and specifically Facebook, as a dominant force in the flow of news in the United States has led to concern that people incur greater isolation from diverse perspectives through filter bubbles (from algorithmic filtering) and echo chambers (from an information environment populated by social recommendations coming from overwhelmingly like-minded others). This evolution in news diffusion comes at a time when Americans report increased affective partisan polarization. In particular, evidence shows increasingly negative attitudes about out-party members. Based on selective exposure and reinforcing spirals model perspectives, we examined the reciprocal relationship between Facebook news use and polarization using national 3-wave panel data collected during the 2016 US Presidential Election. Over the course of the campaign, we found media use and attitudes remained relatively stable. Our results also showed that Facebook news use was related to a modest over-time spiral of depolarization. Furthermore, we found that people who use Facebook for news were more likely to view both pro- and counter-attitudinal news in each wave. Our results indicated that counter-attitudinal news exposure increased over time, which resulted in depolarization. We found no evidence of a parallel model, where pro-attitudinal exposure stemming from Facebook news use resulted in greater affective polarization.

‘Nest tying’ by wild chimpanzees at Bulindi—a variant of a universal great ape behavior?

Tie one on: ‘nest tying’ by wild chimpanzees at Bulindi—a variant of a universal great ape behavior? Matthew R. McLennan. Primates, https://link.springer.com/article/10.1007/s10329-018-0658-7

Abstract: With data accumulating from a growing pool of chimpanzee field studies, new behaviors as well as novel variants on common behaviors continue to be described. Nest construction is a universal behavior in wild great apes. Among chimpanzee populations, reported variation in nest building behavior mostly reflects environmental constraints. Despite the ubiquity of nest making by chimpanzees, only ground nesting has been recognized as a behavioral variant, potentially determined by both environmental and social factors. In a study of nests made by chimpanzees (Pan troglodytes schweinfurthii) in Bulindi, Uganda, I identified a hitherto undescribed nest construction technique, termed ‘nest tying’. Five observed nests lacked strong weight-bearing structures beneath them, such as large branches or a supporting trunk. Instead, the nests appeared ‘tied’ (or ‘tethered’) to an adjacent trunk by looping leafy stems or palm fronds around it and interweaving these into the nest mattress, securing the nest against the trunk; thus, nest tying presumably functions to provide added stability and support. This preliminary report presents a description of the observed nests. Irrespective of whether nest tying constitutes true knot making—commonly considered absent in wild great apes—this nest construction technique would seem to require advanced dexterity and a sophisticated understanding of the mechanical properties of the plants used. Forest fragments in Bulindi are highly degraded. Thus, nest tying—and construction of integrated nests (i.e., utilizing multiple plants, often small trees and shrubs) generally—may be promoted by a relative paucity of suitable nesting trees at this site. Still, insofar as nest building is learned in chimpanzees, different construction techniques including nest tying are potentially acquired through social learning. Further investigation is required to ascertain the prevalence and acquisition of this nest construction technique at Bulindi, and to verify its presence or absence in other habitats.

In women, the biological pre-disposition to sexual problems seems to remain relatively stable over time, that is, environment has no influence

Burri A, Ogata S. Stability of Genetic and Environmental Influences on Female Sexual Functioning. The Journal of Sexual Medicine March 06 2018, https://doi.org/10.1016/j.jsxm.2018.01.020

Abstract

Background: Genetic factors have been implicated in the etiology of female sexual dysfunction. Yet, how much the dynamic nature of sexual functioning is influenced by changes in genetic and/or environmental factors remains unknown.

Aim: To explore temporal stability of genetic and environmental influences on female sexual functioning over a 4-year period.

Methods: Data on desire, arousal, lubrication, orgasm, satisfaction, and pain were collected in 2009 and 2013 using the Female Sexual Function Index and were available for 1,209 British twin women.
Outcomes: To track the stability of genetic influences the Female Sexual Function Index sub-domain and total scores were subject to multivariate twin analyses for repeated measures.

Results: Desire showed a lower heritability at follow-up (37% vs 14%) whereas for arousal and sexual pain the heritability at follow-up was higher compared to baseline (28% vs 34% and 30% vs 45%, respectively). The heritability of lubrication remained stable at 27%. According to the best-fitting additive environmental (AE) Cholesky model for all domains except for sexual pain there were no new genetic factors expressing themselves over the 4-year period, but an addition of new, unique environmental determinants could be observed. For sexual pain an additional genetic factor could be observed at follow-up, explaining 39% of the phenotypic variance.

Clinical Translation: The biological pre-disposition to sexual problems seems to remain relatively stable over time.

Conclusions: This is the first study to investigate the genetic stability of female sexual functioning in a large population sample of women. White ethnicity and the relatively high mean age of women asks for caution in extrapolating the findings to other ethnic and age groups. The findings highlight the value of more in-depth exploration of the non-shared environmental influences that could provide clues to the mechanisms behind remittance and/or persistence of sexual problems. Integration of these findings may provide a useful conceptual framework for the treatment and prevention of certain types of sexual problems.

Zero-sum beliefs are pervasive. These beliefs seem to arise in part due to intuitive mercantilist beliefs that money has value over- and-above what it can purchase, since buyers are seen as less likely to benefit than sellers

Johnson, Samuel and Zhang, Jiewen and Keil, Frank, Psychological Underpinnings of Zero-Sum Thinking (January 28, 2018). Available at SSRN: https://ssrn.com/abstract=3117627 or http://dx.doi.org/10.2139/ssrn.3117627

Abstract: A core proposition in economics is that voluntary exchanges benefit both parties. We show that people often deny the mutually beneficial nature of exchange, instead using zero-sum thinking. Participants read about simple exchanges of goods and services, judging whether each party to the transaction was better off or worse off afterwards. These studies revealed that zero-sum beliefs are pervasive. These beliefs seem to arise in part due to intuitive mercantilist beliefs that money has value over- and-above what it can purchase, since buyers are seen as less likely to benefit than sellers, and barters are often seen as failing to benefit either party (Experiment 1). Zero-sum beliefs are greatly reduced by giving reasons for the exchange (Experiment 2), suggesting that a second mechanism underlying zero-sum thinking is a failure to spontaneously take the perspective of the buyer. Implications for politics and business are discussed.

Ten Things Career Changers Need on Their Resume

Ten Things Career Changers Need on Their Resume. By Alina Dizik. FINS, Sep 26 2011
http://europe-jobs.fins.com/Articles/SBB0001424053111904332804576540560574814434/Ten-Things-Career-Changers-Need-on-Their-Resume

In the last few years, executive resume writer Mary Elizabeth Bradford has noticed more of her clients seeking a career switch, even after having built successful careers in another field.

Nowadays, mid-level career changers -- such as software developers who now work in finance or entrepreneurs who come back into corporate life -- make up more than 45% of her practice. Many struggle to create an attention-grabbing resume, she says.

"The ability to objectively match up relevant skills to the position of choice is invaluable," Bradford says.

Eager to switch careers? Here are 10 ways to improve your resume:


Do a Comprehensive Rewrite

Most job candidates make a few quick changes to their resume before submitting it for a new role. If you are switching careers, re-analyze your skills during the editing process and include every area of the business that you've been able to impact, says Jill Smart, chief human resources officer at Accenture, a management consulting and technology firm with employees in 120 countries.

"People changing careers need to make sure their resume shows the full breadth of their skills -- operations, leadership, management, communication," explains Smart.

For example, Accenture hires former doctors to work in their health and public service practice. Their resumes need to demonstrate not only their relationship-building skills but also how they'll fit into the new business setting.


Use the New Job Description to Write a Summary Paragraph

Experts' opinions are mixed on the need for a resume summary or objective for those looking to stay in their field, but it's an important feature for a career changer, says Bonnie Marcus, a New York-based business coach and founder of Women's Success Coaching, a career coaching firm targeting women.

Include a summary paragraph at the top of your resume and tie "everything in the job description with everything you've accomplished in the past," she says.

For example, if the new position calls for online marketing expertise, make sure any marketing or Web experience is mentioned in this opening paragraph. Since most managers spend less than a minute scanning your resume, make sure the first thing they read ties directly to the job description.


Know What to Exclude

While conveying your skills is important, your resume shouldn't be a dumping ground for every minor accomplishment in your career, says resume expert Alesia Benedict, president of GetInterviews.com.

"Don't list tasks that are not relevant to the new career or you will simply reinforce that you should only be considered for your current type of position," Benedict says.

For example, an accountant shouldn't list certain routine bookkeeping duties if they are eager to leave accounting. Also avoid using specific company or industry terms or acronyms that are only known to those in your field.


Demonstrate Accomplishments With Numbers

Include bullet points that show how you've contributed to the bottom line. Numbers, especially those given in dollars, can quickly give hiring managers an idea of your contributions -- even in an unrelated field, says recruiter Craig Libis, founder of Executive Recruiting Consultants based in Dell Rapids, S.D.

While important on all resumes, for a career changer, numbers can be a simple way for hiring managers to relate to an unfamiliar work history. "Specific numbers [allow] the hiring company the ability to apply what the applicant can do for their company in the future," Libis says.


Add Relatable Job Title Descriptions

Adding a short descriptor after the official job title can help hiring managers easily identify your transferable skills.

"For example, if your job title was 'software engineer,' but you want to transition to project management, consider demonstrating the job title as 'Software Engineer (with a heavy emphasis on Project Management)'," Feldberg explains. But be careful not to exaggerate the truth. "You only want to use this approach if you can do it honestly," she adds.


Match up Keywords

When it comes to resume writing, keywords help you move past the electronic filters. For a career changer, that's the first potential barrier in stepping into a new role; a resume full of accounting keywords, for instance, will have a hard time getting past filters for a job in marketing.

Bradford recommends using job aggregator sites like Indeed.com to identify applicable keywords. Find several job postings for your ideal job, paste the job descriptions into a document and find keywords by highlighting any terms that are job descriptors or mention specific needed skills. Then pick out those keywords that match up with your previous experience and include them throughout the first page of your resume, says Bradford.

"Most job seekers are surprised how many matching and relevant skills they find in these job descriptions," she says.


Use a Mixed Format

When working with career switchers, resume writer Robyn Feldberg creates a functional-style resume on the first page and includes the traditional chronological format on the second page. "In other words, the first page looks like a glorified profile," says Dallas-based Feldberg who runs Abundant Success Coach, a career coaching and resume writing service.

Since the functional format focuses more on skills, you can use it to draw the hiring manager in with relevant experience without worrying about the chronology. Combining both resume formats helps to highlight the various transferable skills while still providing a look at the job history, she adds.



Drop Names to Show Previous Success

Showing that you've been able to succeed and work with established industry leaders in your previous career shouldn't be saved for the interview; instead, weave it into your resume to get a hiring manager's attention, says Theresa Szczurek, chief executive Radish Systems, a Boulder-based software firm. A bullet point may read: "Closed $2 million in new sales in 12 months with industry leaders XYZ," she explains.

Especially when applying for a position where you don't have prior experience, it's important to show that you've have the support of top industry leaders and were able to make a difference in your previous role.


Highlight Non-Work Related Experience

As a career changer, the extracurricular activities on your resume will carry more weight, say experts. Be sure to include activities that relate to your desired role like professional association memberships, volunteering, internships or part-time consulting.

For example, "if you're looking to move into Web or database development, volunteer [your] time ... creating a website or database for schools, churches, non-profits," and then highlight your role on your resume, suggests Mike McBrierty, chief operating officer of the technology staffing division of Eliassen Group, an IT recruiting firm based in Wakefield, Mass.


Find Natural Alignments

From a human resources perspective, there are certain accomplishments that are similar across different management structures and firms.

"Look for things about your current position that would have meaning to the person considering you for the new position," says Luke Tanen who left the music industry to work as the director of the Chicago Innovation Awards. For example, Tanen's mention of closing sponsorship deals was similarly impressive in both fields. "In seeing that the Chicago Innovation Awards were [free] in the job posting, I was quite certain that sponsors play a big role in this program. So I made a point to highlight it as my top bullet point from my past experience securing music sponsorships."

The Prevalence of Sexual Abuse in Institutions in Germany: Overall, 3.1% of adult respondents (women: 4.8%, men: 0.8%) reported abuse

The Prevalence of Sexual Abuse in Institutions: Results From a Representative Population-Based Sample in Germany. Andreas Witt et al. Sexual Abuse: A Journal of Research and Treatment, http://journals.sagepub.com/doi/abs/10.1177/1079063218759323

Abstract: The lifetime prevalence of sexual abuse in institutional settings in Germany was examined in a sample representative of the general adult population (N = 2,437). Participants completed a survey on whether they had ever experienced such abuse, its nature (contact, noncontact, forced sexual, intercourse), the type of institution (e.g. school, club), and the relationship of perpetrator to victim (peer, caregiver, staff member). Overall, 3.1% of adult respondents (women: 4.8%, men: 0.8%) reported having experienced some type of sexual abuse in institutions. Adult women reported higher rates of all types than did men, with rates of 3.9% versus 0.8% for contact sexual abuse, 1.2% versus 0.3% for noncontact sexual abuse, and 1.7% versus 0.2% for forced sexual intercourse. We conclude that a remarkable proportion of the general population experiences sexual abuse in institutions, underscoring the need for development of protective strategies. Especially, schools seem to represent good starting points for primary prevention strategies.

How Counterfeits Infect Genuine Products: The Role of Moral Disgust

Amar, M., Ariely, D., Carmon, Z. and Yang, H. (2018), How Counterfeits Infect Genuine Products: The Role of Moral Disgust. J Consum Psychol. doi:10.1002/jcpy.1036

Abstract: We argue that moral disgust toward counterfeiting can degrade both the efficacy of products perceived to be counterfeits and that of genuine products resembling them. Five studies support our propositions and highlight the infectious nature of counterfeiting: Perceiving a product as a counterfeit made disgust more mentally accessible, and led participants to disinfect the item more and reduce how long they remained in physical contact with it (Study 1). Participants who perceived a mouse as a counterfeit, performed less well in a computer game using the mouse and expressed greater moral disgust, which mediated lowered performance (Study 2). Exposure to a supposedly counterfeit fountain pen in an unrelated prior task infected participants’ performance using a genuine ballpoint pen resembling the “counterfeit;” individual differences in moral attitudes moderated the effect (Study 3). Exposure to a supposedly counterfeit mouse infected performance with a genuine mouse of the same brand; moral disgust mediated this effect (Study 4). Finally, moral disgust mediated lowered efficacy of a supposed counterfeit and that of a genuine item resembling the “counterfeit” (Study 5).

Chimpanzees but not orangutans display aversive reactions toward their partner receiving a superior reward

Chimpanzees but not orangutans display aversive reactions toward their partner receiving a superior reward. Yena Kim et al. bioRxiv, https://doi.org/10.1101/274803

Abstract: Fairness judgment is a fundamental aspect of human cooperation. By carefully balancing the payoffs and efforts with cooperating partner (s) we could either avoid or punish cheaters and stably maintain cooperation. Recent studies investigating the origin of this fairness sentiment have demonstrated that this psychological trait is not unique to humans, but also can be observed in other group-living primates, such as chimpanzees and capuchins, suggesting a convergent evolution of a sense of fairness, with cooperative social life being the selective pressure for it. The current study was designed to test this hypothesis by directly comparing the response to the outcome inequity in two of our closest living relatives, chimpanzees and orangutans, having different social systems, i.e. solitary and patrilocal multi-male multi-female groups. Unlike other inequity experiments, we used a prosocial choice apparatus with different reward distributions (advantageous / disadvantageous) to give subjects an active role of not-sharing foods if they considered it unfair. In addition to the choice, we also recorded the behavioral responses of the apes to the inequity. Throughout the experiments aversive emotional responses toward the disadvantageous inequity were only found in chimpanzees, but not in orangutans, supporting the convergent (or domain-specific) evolution of a sense of fairness. However, this aversion to the inequity did not lead the chimpanzees to actually make selfish choices, indirectly supporting the previous findings that chimpanzees employ a partner choice strategy rather than a punishment for fair cooperation. We also found that hierarchy seems to play an important role in the expression of aversion to inequity and prosocial tendency in chimpanzees.

How Well Do Economists Forecast Recessions? As we already knew, badly.

How Well Do Economists Forecast Recessions? Zidong An ; JoĂŁo Tovar Jalles ; Prakash Loungani. IMF Working Paper No. 18/39. March 5, 2018. http://www.imf.org/en/Publications/WP/Issues/2018/03/05/How-Well-Do-Economists-Forecast-Recessions-45672?cid=em-COM-123-36702

Summary: We describe the evolution of forecasts in the run-up to recessions. The GDP forecasts cover 63 countries for the years 1992 to 2014. The main finding is that, while forecasters are generally aware that recession years will be different from other years, they miss the magnitude of the recession by a wide margin until the year is almost over. Forecasts during non-recession years are revised slowly; in recession years, the pace of revision picks up but not sufficiently to avoid large forecast errors. Our second finding is that forecasts of the private sector and the official sector are virtually identical; thus, both are equally good at missing recessions. Strong booms are also missed, providing suggestive evidence for Nordhaus’ (1987) view that behavioral factors—the reluctance to absorb either good or bad news—play a role in the evolution of forecasts.

Does Students’ Grit Predict Their School Achievement Above and Beyond Their Personality, Motivation, and Engagement? It seems to have little explanatory power.

Does Students’ Grit Predict Their School Achievement Above and Beyond Their Personality, Motivation, and Engagement? Ricarda Steinmayr, Anne F. Weidinger, Allan Wigfield. Contemporary Educational Psychology, https://doi.org/10.1016/j.cedpsych.2018.02.004

Highlights
•    In 2 independent samples, we investigated grit’s relation to school achievement.
•    Established conceptually and empirically related constructs were also considered.
•    Only Grit – perseverance of effort predicted GPA when including the other constructs.
•    Perseverance of effort did not predict GPA when controlling for previous achievement.

    Results question grit’s relevance for school achievement, at least in the short term.

Abstract: Grit—individuals’ perseverance of effort and consistency of interests—was introduced in 2007 as new construct that predicts different achievement outcomes. To date, most studies examining grit’s prediction of achievement have not included other predictors in their analyses. Therefore, we assessed grit’s incremental validity for school achievement above theoretically and empirically related predictors, in two adolescent student samples from Germany. Study 1 (N = 227) examined grit’s relative importance for students’ school grades (GPA, math, German) when controlling for prior school grades, the Big Five personality traits, school engagement, values, expectancies for success, and self-efficacy. In Study 2 (N = 586), intelligence, conscientiousness, and established constructs from motivation and engagement literatures were controlled to investigate grit’s relative importance for GPA, math grades and test performance in math. In both studies, relative weight analyses revealed that the grit subscales added little explanatory power. Results question grit’s unique prediction of scholastic success.
