No gain without pain: The psychological costs of dishonesty. Isabel Thielmann, Benjamin E. Hilbig. Journal of Economic Psychology, https://doi.org/10.1016/j.joep.2018.06.001
Highlights
• Evidence on the psychological costs of dishonesty is restricted to indirect tests.
• We present a more direct test of the costs of lying using the dictator game.
• We compare sharing when endowments are obtained by luck, effort, or lying.
• Endowments obtained through lying are treated as if they were “hard-earned”
• This directly supports that lying involves psychological costs.
Abstract: Psychological accounts of dishonesty propose that lying incurs subjective costs due to threating individuals’ moral self-image. However, evidence is restricted to indirect tests of such costs, thus limiting strong conclusions about corresponding theories. We present a more direct test of the costs of lying. Specifically, if lying is psychologically costly, individuals should feel entitled to gains they obtained through dishonesty – similar to those they actually earned through getting lucky or even investing effort. Correspondingly, in three experiments, we compared individuals’ willingness to share in the dictator game, with varying mechanisms generating the to-be-shared endowment: getting lucky, exerting (cognitive) effort, and lying. We consistently found that individuals were at least as unwilling to share an endowment obtained through dishonesty as an endowment obtained through individual effort or true luck. This suggests that individuals perceived gains obtained through dishonesty as “hard-earned”, thus directly supporting the theory that lying involves psychological costs.

Response trajectories to major life stressors and potential trauma are resilience, recovery, chronic stress, and delayed response. Both trait and state factors are associated with trajectory, so individuals on maladaptive trajectories may be identifiable prospectively or soon following stress exposure
Trajectories of resilience and dysfunction following potential trauma: A review and statistical evaluation. Isaac R. Galatzer-Levy, Sandy H. Huang, George A. Bonanno. Clinical Psychology Review, https://doi.org/10.1016/j.cpr.2018.05.008
Highlights
• A review of n=54 studies demonstrates that resilience is the modal response to major life stressors and potential trauma.
• Across events, individuals cluster into common trajectories of stress response at relatively stable rates including resilience, recovery, chronic stress, and delayed response. The stability of these patterns across events, degree of stress exposure, and populations indicates that they may represent phenotypic human stress responses.
• Despite the stability of trajectories, there is evidence that both trait and state factors are associated with trajectory membership, indicating that individuals on maladaptive trajectories may be identifiable either prospectively or soon following stress exposure, and that trajectory membership may be malleable by interventions that target state-level predictors of risk.
• Trajectory models provide a robust methodology to identify and study clinically relevant responses to stress and potential trauma, and to identify characteristics, predictors, and their potential treatment targets.
Abstract: Given the rapid proliferation of trajectory-based approaches to study clinical consequences to stress and potentially traumatic events (PTEs), there is a need to evaluate emerging findings. This review examined convergence/divergences across 54 studies in the nature and prevalence of response trajectories, and determined potential sources of bias to improve future research. Of the 67 cases that emerged from the 54 studies, the most consistently observed trajectories following PTEs were resilience (observed in: n = 63 cases), recovery (n = 49), chronic (n = 47), and delayed onset (n = 22). The resilience trajectory was the modal response across studies (average of 65.7% across populations, 95% CI [0.616, 0.698]), followed in prevalence by recovery (20.8% [0.162, 0.258]), chronicity (10.6%, [0.086, 0.127]), and delayed onset (8.9% [0.053, 0.133]). Sources of heterogeneity in estimates primarily resulted from substantive population differences rather than bias, which was observed when prospective data is lacking. Overall, prototypical trajectories have been identified across independent studies in relatively consistent proportions, with resilience being the modal response to adversity. Thus, trajectory models robustly identify clinically relevant patterns of response to potential trauma, and are important for studying determinants, consequences, and modifiers of course following potential trauma.

Dimensions of Subjective Age Identity Across the Lifespan
Lindner, Nicole M.,and Brian A Nosek 2018. “Dimensions of Subjective Age Identity Across the Lifespan”. PsyArXiv. June 6. doi:10.17605/OSF.IO/M2Y5R
Abstract: We examined how felt age and desired age differed from chronological age across the age span. With each passing Earth year, felt and desired age do grow older, it just takes longer for the year to go by. Past age 25 or so, subjective aging appears to occur on Mars, where one Earth decade equals only 5.3 Martian years. In some sense, our minds age more slowly than our bodies do.

Examined cortical gyrification associations with psychopathy in a sample of 716 incarcerated individuals; psychopathy was negatively associated with gyrification in the midcingulate cortex and superior parietal cortex
Abnormal cortical gyrification in criminal psychopathy. Tara A. Miskovich et al. NeuroImage: Clinical, https://doi.org/10.1016/j.nicl.2018.06.007
Highlights
• We examined cortical gyrification associations with psychopathy in a sample of 716 incarcerated individuals.
• Psychopathy was negatively associated with gyrification in the midcingulate cortex and superior parietal cortex.
• Factor 1 scores were associated with reduced gyrification in the midcingulate cortex, but increased gyrification in bilateral occipital cortex.
• These results may represent a vulnerability for psychopathy, which may help further elucidate the etiology of this disorder.
Abstract
Background: Psychopathy is a personality disorder characterized by interpersonal and emotional abnormalities (e.g., lack of empathy and guilt) and antisocial behavior. Psychopathy has been associated with a number of structural brain abnormalities, most notably in orbital frontal and anterior/medial temporal regions, that may underlie psychopathic individuals' problematic behaviors. Past research evaluating cortical structure in psychopathy has considered thickness and volume, but to date no study has investigated differences in cortical gyrification, a measure of cortical complexity thought to reflect early neurodevelopmental cortical connectivity.
Methods: We measured the local gyrification index (LGI) in a sample of 716 adult male inmates and performed a whole brain analysis assessing the relationship between LGI and total and factor scores on the Hare Psychopathy Checklist-Revised (PCL-R).
Results: PCL-R scores were negatively associated with LGI measures within the right hemisphere in the midcingulate cortex (MCC) and adjacent regions of the superior frontal gyrus as well as lateral superior parietal cortex. Additionally, PCL-R Factor 1 scores (interpersonal/affective traits) predicted less LGI within the right MCC and adjacent dorsomedial frontal cortex and greater LGI in bilateral occipital cortex. Scores on PCL-R Factor 2, indicating impulsivity and antisocial behaviors, did not predict LGI in any regions.
Conclusions: These findings suggest that psychopathy, particularly the interpersonal and affective traits, are associated with specific structural abnormalities that form during neurodevelopment and these abnormalities may underlie aberrant brain functioning in regions important in emotional processing and cognitive control.

Experts' features enable them to perform better than novices on complex tasks; features include superior long-term and working memory and quicker, better decisions; heritable variation in traits such as motivation and cognition can affect expertise
Animal expertise: mechanisms, ecology and evolution. Reuven Dukas. Animal Behaviour, https://doi.org/10.1016/j.anbehav.2018.05.010
Highlights
• Experts' features enable them to perform better than novices on complex tasks.
• Features include superior long-term and working memory and quicker, better decisions.
• Expertise can affect animal ecology and evolution but data are mostly on humans.
• Heritable variation in traits such as motivation and cognition can affect expertise.
• We need long-term studies on animal expertise and its ecology and evolution.
Abstract: Expertise consists of the features that allow individuals with extensive experience on a given complex task to show superior performance on that task compared to novices. While expertise has been investigated mostly in humans, it is highly relevant for other species as well because it can have strong effects on fitness. Moreover, studying expertise in nonhumans can help us understand human expertise. Several features that distinguish experts within their domain of expertise from novices include (1) greater long-term memory, (2) larger capacity of working memory, (3) better ability to focus attention on the most relevant concurrent tasks, (4) superior ability to anticipate, perceive and comprehend the relevant elements in one's surroundings, (5) quicker and better decisions, and (6) faster and more coordinated motor movements. The development of expertise follows a characteristic pattern of gradual improvement in performance over extended periods devoted to practising a given complex task. Heritable variation in a few traits can affect the rate of expertise acquisition and its peak levels. These traits include motivation to practise, perseverance, basic cognitive abilities such as attention span, working memory capacity, learning rates and memory retention, and various physiological, anatomical and morphological features. Key environmental factors influencing expertise development are parental and social settings, which may encourage investment in the extended practice necessary for achieving superior performance on complex tasks. Future work on the evolutionary biology of expertise should focus on the yet unknown neurobiological mechanisms that underlie it, heritable variation in the traits that enable expertise and their genetic basis, further quantifications of expertise acquisition in natural settings, the fitness consequences of the traits that facilitate top expert performance, and the ecological and evolutionary consequences of expertise.

Has evolution shaped us to fall in love, not just in judging our partners, but in becoming more lovable ourselves? Female sexual desire in courtship & newlywed phases decreases later, making men entering into a long-term commitment based on false assumptions about the amount of sex involved
The Mask of Love and Sexual Gullibility. Roy F. Baumeister, Jessica A. Maxwell, Geoffrey P. Thomas. sydneysymposium.unsw.edu.au/2018/chapters/BaumeisterSSSP2018.pdf
Abstract: Many people describe the time of being newly in love as one of life’s peak experiences. Years later, many are dismayed by the choices they made during love, and many people divorce after thinking they were to be married for life. How did they make such a grievous mistake? Traditional theory assumes that lovers are biased in judgments about their partners. This largely speculative essay suggests that evolution has shaped people to fall in love, not just in judging their partners, but in becoming more lovable themselves. Recent data indicate that female sexual desire during courtship and newlywed phases is often followed by a loss of sexual desire that undermines both spouses’ marital satisfaction. Men may therefore be gullible in terms of entering into a long-term commitment based on false assumptions about the amount of sex involved. This may serve as a useful model for the hypothesis that people become more lovable when in love.

On The Role of Affect in Gullibility: Can Positive Mood Increase, and Negative Mood Reduce Credulity?
On The Role of Affect in Gullibility: Can Positive Mood Increase, and Negative Mood Reduce Credulity? Joseph P. Forgas. sydneysymposium.unsw.edu.au/2018/chapters/ForgasSSSP2018.pdf
Abstract: The uncritical acceptance of false or misleading beliefs is often influenced by sub-conscious affective reactions. This chapter will describe some of the psychological mechanisms responsible for the biasing effects of affect and mood on gullibility and skepticism. A series of experimental studies will be presented showing that mild affective states can influence perceptions of truth, the likelihood to believe misleading information, the tendency to trust interpersonal messages, the detection of deception, and the tendency to see meaning in random or meaningless information. In addition to the influence of mild, temporary moods on gullibility, more enduring and stable affective reactions can also produce gullibility. The theoretical significance of these studies will be discussed, and the practical implications of affectively induced gullibility will be considered.

Large-prize winners experience sustained increases in overall life satisfaction that persist for over a decade and show no evidence of dissipating with time; effects on happiness and mental health are much smaller
Long-run Effects of Lottery Wealth on Psychological Well-being. Erik Lindqvist, Robert Östling, David Cesarini. NBER Working Paper No. 24667, http://www.nber.org/papers/w24667
Abstract: We surveyed a large sample of Swedish lottery players about their psychological well-being and analyzed the data following pre-registered procedures. Relative to matched controls, large-prize winners experience sustained increases in overall life satisfaction that persist for over a decade and show no evidence of dissipating with time. The estimated treatment effects on happiness and mental health are significantly smaller, suggesting that wealth has greater long-run effects on evaluative measures of well-being than on affective ones. Follow-up analyses of domain-specific aspects of life satisfaction clearly implicate financial life satisfaction as an important mediator for the long-run increase in overall life satisfaction.
