Social challenge and threat predict performance and cardiovascular responses during competitive video gaming

Individuals tend to compare themselves with others, and the results of these self-evaluations influence subsequent performance. When individuals perceive an advantage over their rivals (challenge-type response), they achieve higher levels of performance. According to the biopsychosocial model of challenge and threat, benefits of favourable appraisals are partly mediated by cardiovascular efficiency, which is increased by challenge and decreased by threat evaluations. In this study, we tested whether the biopsychosocial model can be extended to predict behavioural outcomes in esports. We expected that challenge-type evaluations would increase performance compared to threat-type evaluations. Eighty-two men were assigned to a challenge or threat group and completed three rounds of Counter-Strike: Global Offensive – a video game popular in esports. Individuals with the highest scores were awarded cash prizes. Cardiovascular markers of challenge and threat, cognitive appraisals, and game scores were recorded. We manipulated the social challenge and social threat evaluation by informing participants that their performance in the initial round was superior (challenge) or inferior (threat) compared with other gamers. We found that individuals with more gaming experience, believed they were better than other gamers, had higher heart rate and, in turn, achieved higher scores. These effects were related to initial situational appraisal at the baseline and were not boosted by feedback provided during the actual performance. These results are the first to document that social comparisons among gamers are accurate in the prediction of future physiological and behavioural outcomes. Furthermore, these findings emphasize that physiological responses mediate relationships between action-related cognitions and performance.     

Suffering from the possibility of status loss: Physiological responses to social identity threat in high status groups

In this research, we examine the emergence of social identity threat among members of high status groups, by assessing physiological responses to threat in addition to more traditional (self‐report) measures. We argue that physiological measures are better suited than explicit responses to indicate the emergence of social identity threat when high status groups face the possibility of future group status loss. In Experiment 1, members of an experimentally created high status group displayed higher systolic blood pressure (SBP) and pulse pressure (PP) when inter‐group status differences were unstable than when they were stable, even though participants in both conditions reported identical levels of collective self‐esteem. In Experiment 2, only male participants (i.e., high status group members) displayed increased SBP and PP when discussing changing gender–status relations in society, particularly when this happened in an inter‐group context (i.e., when discussing with females). The increased threat that emerged under these conditions could not be inferred from self‐reported inter‐group perceptions (endorsement of sexism). We conclude that whereas self‐report measures can help assess how high status group members perceive the current inter‐group situation, physiological measures are needed to reveal the social identity threat they experience when they anticipate the possibility for future change in inter‐group relations.

Personality,threat identification and emotional processing

Individual differences in threat identification moderate the associations of personality with emotional experience and behaviour. The present two studies examined whether adeptness at threat identification also moderates the associations between personality and emotional processing. Participants completed personality scales, different emotional processing measures and a threat versus non‐threat categorization task. Adeptness at threat identification moderated the relations between agreeableness and negative interpretation of ambiguous stimuli, negative reactivity and positive likelihood judgments, and the relation between neuroticism and negative recall. The results supported the view that agreeableness and adeptness at threat identification together form a self‐regulation system. The results may have important implications for trait and health psychology. Copyright © 2009 John Wiley & Sons, Ltd.     

Electrophysiological spatiotemporal dynamics during implicit visual threat processing

Numerous studies have found evidence for corticolimbic theta band electroencephalographic (EEG) oscillations in the neural processing of visual stimuli perceived as threatening. However, varying temporal and topographical patterns have emerged, possibly due to varying arousal levels of the stimuli. In addition, recent studies suggest neural oscillations in delta, theta, alpha, and beta-band frequencies play a functional role in information processing in the brain. This study implemented a data-driven PCA based analysis investigating the spatiotemporal dynamics of electroencephalographic delta, theta, alpha, and beta-band frequencies during an implicit visual threat processing task. While controlling for the arousal dimension (the intensity of emotional activation), we found several spatial and temporal differences for threatening compared to nonthreatening visual images. We detected an early posterior increase in theta power followed by a later frontal increase in theta power, greatest for the threatening condition. There was also a consistent left lateralized beta desynchronization for the threatening condition. Our results provide support for a dynamic corticolimbic network, with theta and beta band activity indexing processes pivotal in visual threat processing.     

Selective processing of threat cues in panic disorder

A computerized Stroop color-naming paradigm was used to investigate attentional biases for selectively processing threat information in panic-disordered patients. Subjects named the colors of neutral words (e.g. TYPICAL), fear words (e.g. PANIC), bodily sensation words (e.g. HEARTBEAT), and catastrophe words (e.g. HEART ATTACK). To control for familiarity with threat concepts, we used clinicians who treat panic disorder as normal control subjects. In contrast to normal controls, panic patients exhibited greater Stroop interference for all threat words, especially those associated with catastrophe. Stroop interference waned during the course of the experiment, thereby indicating habituation to the semantic content of the cues. These findings suggest that panic disorder, like other anxiety disorders, is associated with an attentional bias for processing threatening information.     

Number gestures predict learning of number words

When asked to explain their solutions to a problem, children often gesture and, at times, these gestures convey information that is different from the information conveyed in speech. Children who produce these gesture‐speech “mismatches” on a particular task have been found to profit from instruction on that task. We have recently found that some children produce gesture‐speech mismatches when identifying numbers at the cusp of their knowledge, for example, a child incorrectly labels a set of two objects with the word “three” and simultaneously holds up two fingers. These mismatches differ from previously studied mismatches (where the information conveyed in gesture has the potential to be integrated with the information conveyed in speech) in that the gestured response contradicts the spoken response. Here, we ask whether these contradictory number mismatches predict which learners will profit from number‐word instruction. We used the Give‐a‐Number task to measure number knowledge in 47 children (M_age = 4.1 years, SD = 0.58), and used the What's on this Card task to assess whether children produced gesture‐speech mismatches above their knower level. Children who were early in their number learning trajectories (“one‐knowers” and “two‐knowers”) were then randomly assigned, within knower level, to one of two training conditions: a Counting condition in which children practiced counting objects; or an Enriched Number Talk condition containing counting, labeling set sizes, spatial alignment of neighboring sets, and comparison of these sets. Controlling for counting ability, we found that children were more likely to learn the meaning of new number words in the Enriched Number Talk condition than in the Counting condition, but only if they had produced gesture‐speech mismatches at pretest. The findings suggest that numerical gesture‐speech mismatches are a reliable signal that a child is ready to profit from rich number instruction and provide evidence, for the first time, that cardinal number gestures have a role to play in number‐learning.     

The threat of nuclear war: Some responses

The possibility of nuclear holocaust threatens the very existence of the world community. Biologists, earth scientists, educators, lawyers, philosophers, physicists, physicians, and social scientists have addressed the problem from their special perspectives, and have had substantial impact on the public. Behavior analysts, however, have not as a whole contributed a great deal to the goal of preventing nuclear catastrophe. We argue that the threat of nuclear war is primarily a behavioral problem, and present an analysis of that problem. In addition, we address the difficulty of implementing behavioral interventions that would contribute to the survival of the World.     

Thinking of threats: Economic threat appraisals and health threat appraisals predict differential racial attitudes during COVID-19

We examined whether perceptions of the health and economic threats posed by COVID-19 predict different patterns of intergroup attitudes, using data gathered during the early phase of the pandemic. Using data from 1339 geographically and politically diverse White US residents, we show that subjective economic threat predicted general anti-outgroup attitudes, while subjective health threat predicted negative attitudes towards both Asian and Latinx (“stereotypically foreign”) outgroups but not towards other outgroups. Among 303 geographically and politically diverse Black US residents, the pattern instead suggested that threat (regardless of type) was associated with reduced evaluative differentiation between racial ingroups and outgroups.     

Physiological responses in blood phobics

Eighteen patients with blood phobia were shown a film of thoracic operations containing large amounts of blood. Their heart rate (HR) and blood pressure (BP) were measured continuously before, during and after the watching of the film. The group data showed a diphasic response; an increase in HR and BP from baseline to the beginning of the film, and then a sharp drop in these parameters with the lowest values 4 min after the film was turned off. Individual data from 5 patients who fainted or were on the edge of doing so, showed massive bradycardia or drop in BP or both. In all of these patients at least one (range 1–33) 5-sec period of asystole was recorded. Possible theoretical explanations for this characteristic response pattern are discussed.     

Unconscious processing of coarse visual information during anticipatory threat

Rapid detection of threats has been proposed to rely on automatic processing of their coarse visual features. However, it remains unclear whether such a mechanism is restricted to detection of threat cues, or whether it reflects a broader sensitivity to even neutral coarse visual information features during states of threat. We used a backward masking task in which participants discriminated the orientation of subliminally presented low (3 cpd) and high (6 cpd) spatial frequency gratings, under threat (of shock) and safe conditions. Visual awareness of the gratings was assessed objectively using an additional localization task. When participants were unaware of the gratings, above chance and improved discrimination of low-spatial frequency gratings was observed under threat compared to safe trials. These findings demonstrate unconscious processing of neutral coarse visual information during threat state, supporting the view that automatic threat detection may rely on a general facilitation of coarse features irrespective of threat content.     

Selective processing of threat cues in posttraumatic stress disorder

Vietnam combat veterans with (n = 15) and without (n = 15) posttraumatic stress disorder (PTSD) performed a modified Stroop task in which they named the colors of neutral words (e.g., INPUT), positive words (e.g., LOVE), obsessive-compulsive disorder (OCD) words (e.g., GERMS), and PTSD words (e.g., BODYBAGS). In contrast to normal controls, PTSD patients took significantly longer to color-name PTSD words than to color-name neutral, OCD, and positive words. Because Stroop interference reflects involuntary semantic activation, it may provide a quantitative measure of intrusive cognitive activity--the hallmark symptom of PTSD.     

Negative processing biases predict subsequent depressive symptoms

This study investigated the possible relationship between negative processing biases and subsequent depression. The Scrambled Sentences Test (SST), a measure of processing bias, was administered to a large sample of undergraduates. Participants also completed self-report measures of thought suppression tendencies, current level of depression, and lifetime worst-depression symptoms. High scores on the SST, reflecting a negative processing bias, predicted depression symptoms measured 4 to 6 weeks later, even after controlling for concurrent and past depression. The SST was administered both with and without cognitive load to all participants. The SST with load predicted subsequent depression for both men and women. The SST without load predicted depression for women only. The SST difference score, a measure of the change in scores between the no-load and load conditions, was a significant predictor of subsequent depression for men but not women. Among men, the combination of high thought suppression with either high SST-load scores or high SST difference scores proved to be a particularly strong indicator of vulnerability to subsequent depression.     

Personality,threat and affective responses to cultural diversity

The present study tried to reconcile assumptions from Terror Management Theory that individual differences in openness to diversity are enhanced by existential threat with own recent findings suggesting that individual differences are diminished by threat. A model was supported assuming that it is the nature of the threat that determines which pattern will hold. We predicted that for stress‐related but not for social traits, threat enhances individual differences in reactions to diversity. Students were confronted with a videotaped meeting of a homogeneous versus diverse work group. Threat was induced using a Terror Management Intervention. Indeed, whereas for Emotional Stability individual differ ences in responses to diversity were restricted to conditions of threat, for Social Initiative, individual differences solely occurred under normal circumstances.

Frontal and parietal EEG asymmetries interact to predict attentional bias to threat

Frontal and parietal electroencephalographic (EEG) asymmetries mark vulnerability to depression and anxiety. Drawing on cognitive theories of vulnerability, we hypothesise that cortical asymmetries predict attention to threat. Participants completed a dot-probe task in which bilateral face displays were followed by lateralised targets at either short (300 ms) or long (1050 ms) SOA. We also measured N2pc to face onset as an index of early attentional capture. At long SOA only, frontal and parietal asymmetry interacted to predict attentional bias to angry faces. Those with leftward frontal asymmetry showed no attentional bias. Among those with rightward frontal asymmetry those with low right parietal activity showed vigilance for threat, and those with high right parietal activity showed avoidance. Asymmetry was not related to the N2pc or to attentional bias at the short SOA. Findings suggest that trait asymmetries reflect function in a fronto-parietal network that controls attention to threat.     

Anxiety sensitivity and attentional bias to threat interact to prospectively predict anxiety

The purpose of the present study was to examine anxiety sensitivity, attentional bias to threat (ABT), and the aggregate influence of these constructs as prospective predictors of anxiety. Participants (N = 176) completed a baseline assessment session which included the completion of self-report measures of anxiety and anxiety sensitivity, as well as an eye-tracking task in which eye movements were recorded during the viewing of neutral and threat images. Measures of anxiety and anxiety sensitivity were completed again as part of an online questionnaire battery at a 1-year follow-up session. As predicted, baseline anxiety sensitivity and ABT predicted anxiety at 1-year follow-up even after accounting for baseline anxiety. However, these main effects were qualified by a significant interaction effect such that those high in anxiety sensitivity at baseline reported relatively higher anxiety at the 1-year follow-up, but only if they also exhibited higher levels of ABT at baseline. Results suggest that individuals with this combination of vulnerability factors (high levels of both anxiety sensitivity and ABT) may be at particularly high risk for developing anxiety and may benefit from preemptive efforts to reduce ABT.     

Working memory and two-digit number processing

The processing of two-digit numbers in comparison tasks involves the activation and manipulation of magnitude information to decide which number is larger. The present study explored the role of different working memory (WM) components and skills in the processing of two-digit numbers by examining the unit–decade compatibility effect with Arabic digits and number words. In the study, the unit–decade compatibility effect and different WM components were evaluated. The results indicated that the unit–decade compatibility effect was associated to specific WM skills depending on the number format (Arabic digits and number words). We discussed the implications of these results for the decomposed view of two-digit numbers.     

Children's number processing is context dependent

The aim of this paper was to test the hypothesis of a context dependence of number processing in children. Fifth-graders were given two numbers presented successively on screen through a self-presentation procedure after being asked either to add or subtract or compare them. We considered the self-presentation time of the first number as reflecting the complexity of the encoding for a given planned processing. In line with Dehaene's triple-code model, self-presentation times were longer for additions and subtractions than for comparisons with two-digit numbers. Alternative interpretations of these results in terms of more cognitive effort or more mental preparation in the case of addition and subtraction than comparison are discussed and ruled out.
