Proactive inhibitory control: A general biasing account

Flexible behavior requires a control system that can inhibit actions in response to changes in the environment. Recent studies suggest that people proactively adjust response parameters in anticipation of a stop signal. In three experiments, we tested the hypothesis that proactive inhibitory control involves adjusting both attentional and response settings, and we explored the relationship with other forms of proactive and anticipatory control. Subjects responded to the color of a stimulus. On some trials, an extra signal occurred. The response to this signal depended on the task context subjects were in: in the ‘ignore’ context, they ignored it; in the ‘stop’ context, they had to withhold their response; and in the ‘double-response’ context, they had to execute a secondary response. An analysis of event-related brain potentials for no-signal trials in the stop context revealed that proactive inhibitory control works by biasing the settings of lower-level systems that are involved in stimulus detection, action selection, and action execution. Furthermore, subjects made similar adjustments in the double-response and stop-signal contexts, indicating an overlap between various forms of proactive action control. The results of Experiment 1 also suggest an overlap between proactive inhibitory control and preparatory control in task-switching studies: both require reconfiguration of task-set parameters to bias or alter subordinate processes. We conclude that much of the top-down control in response inhibition tasks takes place before the inhibition signal is presented.     

Perception of intensity of sperm competition on the part of males

Preferences for certain pornographic themes are hypothesized to have been influenced by our evolutionary history, where sperm competition could play a significant role. The mating system in our australopithecine ancestors, as well as in modern human societies, however, suggests that polygyny (characterized by low risk of sperm competition) has predominated over multi-male multi-female mating systems where high sperm competition is expected. In this study, a sample of men (N = 96) was investigated for their preferences for sexually explicit material showing low (sexual interaction with three women), moderate (one man and one woman) and high intensity of sperm competition (one woman and two men). The participants showed a strong and highly consistent preference for pictures showing moderate and low intensity of sperm competition. These preferences were not influenced by sociosexuality, pornography consumption or attitudes toward pornography. It is suggested that these preferences may mirror psychological adaptations for sperm competition which are activated when the risk of cuckoldry is high. Certain circumstances, where preferences for cues associated with high intensity of sperm competition would be adaptive, are discussed.     

Religiosity,Secular Participation,and Cultural Socialization: A Case Study of the 1933–1942 Urban English Cohort

The nature of secularization is of enduring interest in the social science of religion. Numerous recent papers have established downward cohort trends as characterizing religious change. We examine potential mechanisms by assessing cultural participation and secular engagement during the formative period of one cohort. We provide estimates of active and nominal religiosity, nonreligion and religious belief for those born between 1933 and 1942, using multiple surveys fielded between 1957 and 2018. We model the association between religiosity and secular cultural and social participation for this cohort in 1957, then examine how cultural socialization in childhood relates to religiosity in their later adulthood using surveys fielded between 2005 and 2007. Increased secular competition is found to be associated with less active religiosity. These trends were underpinned by an ethic of increasing autonomy for the young. We conclude by affirming the link between increasing secular competition, long-run modernization, and changing cultural socialization.     

Children's prosocial behavioural intentions towards outgroup members

When will children decide to help outgroup peers? We examined how intergroup competition, social perspective taking (SPT), and empathy influence children's (5–10 years, N = 287) prosocial intentions towards outgroup members. Study 1 showed that, in a minimal group situation, prosociality was lower in an intergroup competitive than in a non‐competitive or interpersonal context. Study 2 revealed that, in a real groups situation involving intergroup competition, prosociality was associated with higher empathy and lower competitive motivation. In a subsequent non‐competitive context, there were age differences in the impact of SPT and competitive motivation. With age, relationships strengthened between SPT and prosociality (positively) and between competitiveness and prosociality (negatively). Among older children, there was a carry‐over effect whereby feelings of intergroup competitiveness aroused by the intergroup competitive context suppressed outgroup prosociality in the following non‐competitive context. Theoretical and practical implications for improving children's intergroup relationships are discussed.     

A world survey of secular-religious competition: state religious policy from 1990 to 2014

ABSTRACT

This study argues that the competition between secular and religious actors significantly influences State religion policy (SRP) (the secular-religious competition perspective). I examine this proposition using the Religion and State Round 3 (RAS3) dataset which measures 117 types of SRP between 1990 and 2014 in 183 countries and territories. The results show that while SRP is overall becoming more common, only 3.7% of countries made no changes in their SRP and 69.5% of countries both (a) added or intensified at least one SRP and (b) dropped or decreased the intensity of at least one SRP. This finding remains consistent when looking at each of the 117 types of SRP independently, as well as when controlling for the country’s majority religion and world region. These results are consistent with the secular-religious competition perspective.     

Stress reappraisal during a mathematics competition: testing effects on cardiovascular approach-oriented states and exploring the moderating role of gender

Background and objectives: Effects of reappraising stress arousal during an interpersonal competition were tested on physiological functioning and performance. Additionally, the moderating role of gender was explored.

Design and method: Participants (N?=?279) were randomly assigned to a stress reappraisal, stress-is-debilitating, or a neutral control condition. Reappraisal materials educated participants about the adaptive benefits of stress, whereas stress-is-debilitating materials instructed participants to avoid stress. Control materials did not mention stress. Participants then competed against a gender-matched confederate on a 10-minute math performance task while cardiovascular reactivity was assessed. Participants were instructed to complete math problems as quickly and accurately as they could and were informed that a winner and loser would be determined by the resulting math scores.

Results: Reappraising stress arousal led to more adaptive challenge-like cardiovascular responses, but no condition effects were observed on math performance. Exploratory analyses revealed that reappraisal instructions were effective for improving physiological functioning and facilitating performance for men, but women were unaffected by the manipulation.

Conclusions: Reappraising stress arousal can improve physiological functioning during interpersonal competitions, but effects may be limited to men. Implications for future research are discussed.
