A tale of two processes: On Joseph Henrich’s the secret of our success: How culture is driving human evolution,domesticating our species,and making us smarter

We situate Henrich’s book in the larger research tradition of which it is a part and show how he presents a wide array of recent psychological, physiological, and neurological data as supporting the view that two related but distinct processes have shaped human nature and made us unique: cumulative cultural evolution and culture-driven genetic evolution. We briefly sketch out several ways philosophers might fruitfully engage with this view and note some implications it may have for current philosophic debates in moral and political theory and over the nature of extended cognition. We end by noting how Henrich’s view of the source of cultural design and innovation, and the prominence of place he gives to the extended process of cultural evolution, cuts against a cluster of broad but common views about human minds, recasting putative bugs as features and indicating that many of the distinctive features of our individual minds evolved to allow them to be effective cogs in the larger, more productive cultural machine.     

The influence of natural contour and face size on the spatial frequency tuning for identifying upright and inverted faces

Psychological Research - It has previously been proposed that holistic face processing is based on low spatial frequencies (SFs) whereas featural processing relies on higher SFs, a hypothesis still...     

Seeing is Knowing: On the Predictive Accuracy of Self‐ and Informant Reports for Prosocial and Moral Behaviours

Under certain circumstances, well‐known others (so‐called informants) may possess unique insights into targets' personality traits beyond the targets' self‐views. Specifically, as proposed by the self–other knowledge asymmetry model, an incremental predictive ability of informants is most likely for traits and corresponding behaviours that are clearly visible to others and highly evaluative in nature. In two studies, we provide an empirical test of this proposition and extend prior research to one of the most important domains of interpersonal interaction: prosocial and moral behaviours. Specifically, we investigate the unique predictive power of informant reports in trait Honesty–Humility for fairness in the dictator game and dishonesty in a cheating paradigm. Importantly, while both these classes of behaviour are highly evaluative in nature, only fairness is clearly visible to others. Correspondingly, in line with the self–other knowledge asymmetry model, our results reveal unique predictive accuracy of informant reports for fairness. For dishonesty, by contrast, there was no conclusive evidence for incremental predictive power of informant reports. This implies that informants may indeed provide valuable information beyond targets' self‐reports on trait aspects driving fair behaviour, but that targets themselves are their own best experts when it comes to judging trait aspects driving dishonest behaviour.

Personality Traits Predict Smartphone Usage

The present study investigates to what degree individual differences can predict frequency and duration of actual behaviour, manifested in mobile application (app) usage on smartphones. In particular, this work focuses on the identification of stable associations between personality on the factor and facet level, fluid intelligence, demography and app usage in 16 distinct categories. A total of 137 subjects (87 women and 50 men), with an average age of 24 (SD = 4.72), participated in a 90‐min psychometric lab session as well as in a subsequent 60‐day data logging study in the field. Our data suggest that personality traits predict mobile application usage in several specific categories such as communication, photography, gaming, transportation and entertainment. Extraversion, conscientiousness and agreeableness are better predictors of mobile application usage than basic demographic variables in several distinct categories. Furthermore, predictive performance is slightly higher for single factor—in comparison with facet‐level personality scores. Fluid intelligence and demographics additionally show stable associations with categorical app usage. In sum, this study demonstrates how individual differences can be effectively related to actual behaviour and how this can assist in understanding the behavioural underpinnings of personality.

Reconciling Compensatory and Noncompensatory Strategies of Cue Weighting: A Causal Model Approach

When forming a judgment about any unknown item, people must draw inferences from information that is already known. This paper examines causal relationships between cues as a relevant factor influencing how people determine the amount of weight to place on each piece of available evidence. We propose that people draw from their beliefs about specific causal relationships between cues when determining how much weight to place on those cues, and that understanding this process can help reconcile differences between predictions of compensatory and lexicographic heuristic strategies. As causal relationships change, different cues become more or less important. Across three experiments, we find support for the use of causal models in determining cue weights, but leave open the possibility that they work in concert with other strategies as well. We conclude by discussing relative strengths and weaknesses of the causal model approach relative to existing models, and suggest areas for future research.

Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies

The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

Assessing the Mediating Effect of Relationship Dynamics Between Perceptions of Problematic Media Use and Relationship Satisfaction

Previous research has indicated that it is common for couples to experience conflict over media use. However, until recently clinicians and researchers have not explored the implications of media use within romantic relationships. The purpose of this study is to examine the relationship between individuals’ perception of problematic media use in connection with relationship satisfaction, and to what extent demand-withdraw and criticism-defensiveness dynamics mediate this association. Data was collected with a sample of 242 respondents completing an online survey. Results showed that demand-withdraw and criticism-defensiveness patterns were found to be negatively associated with relationship satisfaction, and that the association between problematic media use and relationship satisfaction was partially mediated by the demand-withdraw and criticism-defensiveness patterns. Based on these results, there is potential for clinicians to view couple media use as a process level interaction, and by doing so, clinicians will be better able to implement interventions that utilize clients’ media use to promote relationship satisfaction and stability while reducing problematic media use.     

The Emotional Foundation of Political Cognition: The Impact of Extrinsic Anxiety on the Formation of Political Tolerance Judgments

Common sense recognizes emotion's ability to influence judgments. We argue that affective processes, in addition to generating feeling states, also influence how political cognition is manifested. Drawing on the theory of affective intelligence, we examine the role that anxiety plays in how and when people rely on predispositions and when they rely on contemporaneous information in making political tolerance judgments. We report on two experimental studies to test our arguments. In the first study we find that extrinsic anxiety generates a resistance response among subjects who hold a strong predisposition and a receptive response among those who do not. In the second study we present subjects with explicit "frames" exposing them to a pro- or anti-free speech message. We find that extrinsic anxiety enhances responsiveness to frames while an absence of anxiety diminishes the impact of these frames. Taken together these results show that affective processes shape how people make political judgments.     

The relationships between parenting stress,parenting behaviour and preschoolers' social competence and behaviour problems in the classroom

Young children develop social and emotional competence through interactions with others in the two major contexts in which they spend time: home and preschool. This study examined whether parenting stress in the home context is related to the children's behaviour while in preschool. Previous research has suggested that parenting stress negatively influences parenting behaviour, which in turn has been shown to impact children's development. This study examined the direct relationship between parenting stress and children's behaviour in two types of preschool programmes: private day care centres and Head Start. Parenting stress was significantly related to teacher ratings of social competence, internalizing behaviours, and externalizing behaviours, and the effects of parenting behaviour do not appear to mediate this relationship. Parenting stress was most strongly related to children's social competence. Parents' reports of expectations for their child's behaviour appear to weakly moderate the relationship between externalizing behaviour and parenting stress. This study suggests that examination of a parent's level of stress, in addition to parenting practices, may be important in research and interventions with preschool children's behaviour and social competence.
