Working Memory Capacity in High Trait-anxious and Repressor Groups

The verbal reasoning performance of high-anxious (high trait anxiety, low defensiveness), defensive high-anxious (high trait anxiety, high defensiveness), repressor (low trait anxiety, high defensiveness), and low-anxious (low trait anxiety, low defensiveness) groups was examined under high and low memory load conditions. As predicted by the processing efficiency theory (Eysenck & Calvo, 1992), the slowing of reasoning speed with the high memory load was disproportionately great for the high-anxious and defensive high-anxious groups. The effects of high memory load on reasoning speed were the same for the low-anxious and repressor groups, suggesting that both groups had equivalently low levels of worrying (and other anxiety related) task-irrelevant thoughts. Theoretical implications of these, and other findings, for the understanding of repressors were discussed.     

Comment on “group shift to caution at the race track”

A recent study by McCauley, Stitt, Woods, and Lipton on the effects of three-person group discussions at the race track claims a systematic shift toward greater caution in betting choices, a result in contrast with the typical laboratory finding of group risky shifts. This study is criticized for an apparent statistical oversight. It is quite plausible that an apparent cautious shift could have arisen as an artifact of the distribution of original positions of the bettors being skewed in the risky direction. This type of potential artifact has been discussed before in the risky shift literature, but is especially stark in the present context. It is recommended as standard procedure for the present data and other similar data that initial group position be indexed with the median rather than the mean, or that other precautions be taken to eliminate the confounding effects of skewness on the assessment of risky or cautious group shifts.     

Anxiety symptom interpretation and performance expectations in high-anxious,low-anxious,defensive high-anxious and repressor individuals

To date, no research has investigated score predictions and anxiety interpretation in high-anxious, low-anxious, defensive high-anxious and repressor individuals. This study examined Eysenck’s (1997) predictions for cognitive biases on future performance expectations in all four groups. This study was conducted in an ecologically-valid sporting environment. Competitive shooters completed the Marlowe–Crowne Social Desirability Scale and the Sport Anxiety Scale prior to a major competition. Percentile splits identified the four defensiveness/anxiety groups. The modified Competitive Sport Anxiety Inventory-2 was used to assess the intensity and direction of anxiety prior to competition. Participants predicted their expected shooting score. The hypothesis that repressors would interpret their anxiety as more facilitative to performance compared to low-anxious individuals was partially supported. Repressors were more optimistic in their performance prediction in contrast to defensive high-anxious performers who, in turn, were more pessimistic compared to the other two groupings. High-anxious performers, contrary to predictions, demonstrated optimism in their future performance. The findings of this study corroborate the theoretical predictions and the evidence from previous studies with sport performers. Future research should continue to investigate the influence of cognitive biases on performance predictions in sporting environments using Weinberger et al.’s classifications.     

Anxiety symptom interpretation in high-anxious, defensive high-anxious, low-anxious and repressor sport performers

For the first time in a sport setting this study examined the intensity and direction of the competitive state anxiety response in collegiate athletes as a function of four different coping styles: high-anxious, defensive high-anxious, low-anxious and repressors. Specifically, the study predicted that repressors would interpret competitive state anxiety symptoms as more facilitative compared to high-anxious, defensive high-anxious, and low-anxious performers. Separate Multivariate Analyses of Variance (MANOVA) were performed on the intensity and direction subscales of the modified Competitive State Anxiety Inventory-2 (CSAI-2). A significant main effect was identified for trait worry revealing that low trait anxious athletes reported lower intensities of cognitive and somatic anxiety and higher self-confidence and interpreted these as more facilitative than high trait anxious athletes. The prediction that performers with a repressive coping style would interpret state anxiety symptoms as more facilitative than performers with non-repressive coping styles was not supported.     

Effects of focus of attention on physiological,behavioural, and reported state anxiety in repressors,low-anxious,high-anxious,and defensive high-anxious individuals

Abstract

Discrepancies between physiological activity, behavioural anxiety, and self-reported anxiety were examined when focus of attention was manipulated in a public speech task for four groups of individuals: repressors, low-anxious, high-anxious, and the defensive high-anxious. They were exposed to self-focus (when their behaviour was socially evaluated) and other-focus (when their behaviour was not socially evaluated) conditions. Repressors had consistently the lowest level of self-reported anxiety, but had consistently greater physiological activity in all conditions and greater behavioural anxiety in the self-focus condition. The high-anxious showed the opposite pattern, i.e. their self-reported anxiety was greater than their physiological and behavioural anxiety, and this finding was significant in the self-focus condition. No significant pattern of discrepancy was found for the low-anxious or defensive high-anxious groups. The findings are discussed and interpreted within the framework of recent cognitive models of anxiety.     

Anxiety not only increases,but also alters early error-monitoring functions

Anxiety has profound influences on a wide range of cognitive processes, including action monitoring. Eventrelated brain potential (ERP) studies have shown that anxiety can boost early error detection mechanisms, as reflected by an enhanced error-related negativity (ERN) following errors in high-anxious, as compared with low-anxious, participants. This observation is consistent with the assumption of a gain control mechanism exerted by anxiety onto error-related brain responses within the dorsal anterior cingulate cortex (ACC). However, whether anxiety simply enhances or, rather, alters early error detection mechanisms remains unsolved. In this study, we compared the performance of low-versus high-trait-anxious participants during a go/no-go task while high-density EEG was recorded. The two groups showed comparable behavioral performance, although levels of state anxiety increased following the task for high-anxious participants only. ERP results confirmed that the ERN/Ne to errors was enhanced for high-anxious, relative to low-anxious, participants. However, complementary topographic analyses revealed that the scalp map of the ERN/Ne was not identical between the two groups, suggesting that anxiety did not merely increase early error detection mechanisms, but also led to a qualitative change in the early appraisal of errors. Inverse solution results confirmed a shift within the ACC for the localization of neural generators underlying the ERN/Ne scalp map in high-anxious participants, corroborating the assumption of an early effect of anxiety on early error-monitoring functions. These results shed new light on the dynamic interplay between anxiety and error-monitoring functions in the human brain.

On predicting minority influence

Paralleling closely an experiment on group polarization by Vinokur and Burnstein (1978), subjects discussed one of three risky, cautious, or neutral choice dilemmas. For each of the value items, one half of the six-person groups consisted of a cautious minority and a risky majority; the other half consisted of a risky minority and a cautious majority. The minorities always consisted of trained confederates. The results indicated that on risky items minorities that argued for risk had more influence than minorities advocating caution; on neutral and cautious items the majority was not influenced by the minority whether it advocated the risky or cautious alternative.     

The relationship between riskiness and confidence in choice dilemma decisions

The relationship between riskiness of decisions and confidence in decisions was examined using Choice Dilemma items. Graphs show a clear curvilinear relationship between riskiness and confidence; on both risky items and cautious items greater confidence is associate with extremely risky and extremely cautious decisions than with moderate ones. it was also demonstrated that individual subjects have more confidence in their extreme decisions than in their moderate ones.     

Attentional bias in anxiety: a behavioral and ERP study

Accumulating evidence suggests the existence of a processing bias in favor of threat-related stimulation in anxious individuals. Using behavioral and ERP measures, the present study investigated the deployment of attention to face stimuli with different emotion expressions in high-anxious and low-anxious participants. An attention-shifting paradigm was used in which faces with neutral, angry, fearful, sad, or happy expressions were presented singly at fixation. Participants had to fixate on the face cue and then discriminate a target shape that appeared randomly above, below, to the left, or right of the fixated face. The behavioral data show that high-anxious participants were slower to respond to targets regardless of the emotion expressed by the face cue. In contrast, the ERP data indicate that threat-related faces elicited faster latencies and greater amplitudes of early ERP components in high-anxious than in low-anxious individuals. The between-group pattern in ERP waveforms suggests that the slower reaction times in high-anxious participants might reflect increased attentional dwelling on the face cues, rather than a general slowing of response enacting.     

Individual differences in preschool object play: The influences of anxiety proneness and peer affiliation

Individual differences in anxiety and peer affiliation were investigated as factors influencing variability of object play among preschoolers. Eighteen three-year-olds were divided into high- and low-anxious groups on the bases of separation anxiety and general anxiety scales. Their mature and immature object play, their peer affiliation, and their peer-watching behaviors were observed in preschools. Low-anxious children played more, showed more mature play, and watched peers less when they were alone; high-anxious children showed no play increases but watched peers more when alone. Separation anxiety scores predicted preschool differences more sensitively than general anxiety scores. It was theorized that separation anxiety related mechanisms hinder children's ability to fully profit from preschool experiences.     

Exercise-produced arousal, film-induced arousal and attribution of internal state.

Respiration rates were monitored on 20 high-anxious and 20 low-anxious female Ss while they were watching an anxiety-provoking film on industrial accidents. Half of the Ss exercised on a bicycle while half remained seated throughout their viewing of the film. Exercised Ss reported feeling less anxious while viewing the accidents compared with the inactive controls. All groups recalled similiar amounts of the film content, and respiration rates did not increase while viewing the accidents. Results of self-report of anxiety are consistent with a recently advanced theory of objective self-awareness.     

Effects of test anxiety, ego stress, and attentional skills training on arithmetic reasoning: An experimental evaluation of a brief counseling strategy

Abstract Two hundred forty high school students (120 male and 120 female) in India performed a moderately difficult multiple choice Arithmetic Reasoning task after undergoing short-term (40 minutes) cognitive treatment in the form of Attentional Skills Training. A 2 × 2 × 2 (Test Anxiety x Attentional Skills Training x Stress) design with separate analysis for boys and girls indicated these results: with intervention the high anxiety subjects under ego stress conditions, compared to their high-anxious control, low-anxious ego stress, or low-anxious control counterparts, reported the maximum significant improvement in performance on the Arithmetic Reasoning test. The low-anxiety subjects performed consistently well with or without treatment or stress conditions. The findings shed new light on the attentional theory of test anxiety, and it was reasoned that long-term effects of cognitive treatment be studied by using varied performance tasks (difficulty level controlled) on different gender and age groups across cultures.     

Repressive coping style and autonomic reactions to two experimental stressors in healthy men and women

Autonomic and affective responses to two different stress tasks were measured in 45 males and 74 females, categorized as repressive, true low-anxious, true high-anxious, and defensive high-anxious. Electrodermal activity (EDA) was used as a measure of sympathetic activity and the high frequency (HF) spectral component of heart rate variability as a measure of parasympathetic activity. Contrary to our predictions, reactivity of repressors did not differ from the reactivity of true low-anxious participants. The results draw attention to previous inconsistent findings within the literature on repressive coping style and autonomic nervous system dysregulation. It is suggested that future research could benefit from the use of more consistent operationalizations of the repressive coping construct and from comparing alternative measures of repressive coping within the same study.     

Manipulation of focus of attention and its effects on anxiety in high-anxious individuals and repressors

Abstract

There were four groups of participants: low-anxious (low anxiety-low defensiveness), repressors (low anxiety-high defensiveness), high-anxious (high anxiety-low defensiveness), and defensive high-anxious (high anxiety-high defensiveness). They were exposed to self-focus and other-focus conditions, and self-report, physiological, and behavioural measures of anxiety were recorded. The focus manipulation (self vs. other) was effective, with all four groups having higher self-reported anxiety in the self-focus condition. It was found that self-focused attention accounted for a significant amount of variation in self-reported anxiety. The findings were discussed within the theoretical framework proposed by Eysenck (1997).

Polarized Norms and Social Frames of Reference: A Test of the Self-Categorization Theory of Group Polarization

Self-categorization theory (Turner, 1985; Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) explains group polarization as conformity to a polarized norem which defines one's own group in contrast to other groups within a specific social context. Whether the ingroup norm is polarized or not depends on the social comparative context within which the ingroup defines itself. It was predicted from self-categorization theory that an ingroup confronted by a risky outgroup will polarize toward caution, an ingroup confronted by a caution outgroup will polarize toward risk, and an ingroup in the middle of the social frame of reference, confronted by both risky and cautious outgroups, will not polarize but will converge on its pretest mean. Our experiment adopted a modified version of the risky-shift paradigm, in which subjects gave pretest, posttest, and group consensus recommendations on three choice dilemma item-types (risky, neutral, or risky). The frame of reference was manipulated by confronting the ingroup with an outgroup lying on one or the other side, or both sides, of the ingroup distribution. This procedure was successful in producing a polarized theoretical ingroup norm in the appropriate conditions. Subjects' posttest opinions converged on their estimations of the consensual ingroup position, which in turn was polarized or not in line with the theoretical norm. There was some evidence that the degree of behavioral convergence and estimations of the ingroup consensus were a partial function of the extent to which subjects identified the group. There was also the usual main effect for item-type: Subjects converged on a norm polarized toward risk on risky items and toward caution on catious items. The results are consistent with self-categorization theory.     

The effects of discussion on group and individual choices among bets

The effects of discussion on subsequent group and individual choices are studied in a situation where subjects choose between a sure gain of varying amount and five probability levels associated with larger gains of expected value equal to that of the sure gain. At the end of the experiment, a single bet, chosen at random, is played for money. Before discussion, subjects have to guess the percentage of similar, more risky and more cautious choices made by their peers for each of the six bets. As predicted by a majority-rule decision-making model significant risky shifts were observed for relatively low values of sure gain. For higher values, however, groups tended to be more cautious than individuals. The final private choices of individuals were significantly more risky than their initial decisions. Most individuals apparently thought they were at least as risky as most others. This finding was due, however, primarily to the responses of subjects who chose the highest risk-level (the ceiling effect) and, secondly, to the consistent tendency of most individuals to guess that others make the same choices as they themselves. It is concluded that majority influence seems a satisfactory explanation of group risky shifts observed in the present study, but it cannot account for modifications of group and individual choices in all risk-taking situations.     

Anxiety and cognitive efficiency: Differential modulation of transient and sustained neural activity during a working memory task

According to the processing-efficiency hypothesis (Eysenck, Derakshan, Santos, & Calvo, 2007), anxious individuals are thought to require greater activation of brain systems supporting cognitive control (e.g.,dorsolateral prefrontal cortex; DLPFC) in order to maintain equivalent performance to nonanxious subjects. A recent theory of cognitive control (Braver, Gray, & Burgess, 2007) has proposed that reduced cognitive efficiency might occur as a result of changes in the temporal dynamics of DLPFC recruitment. In this study, we used a mixed blocked/ event-related fMRI design to track transient and sustained activity in DLPFC while high- and low-anxious participants performed a working memory task. The task was performed after the participants viewed videos designed to induce neutral or anxiety-related moods. After the neutral video, the high-anxious participants had reduced sustained but increased transient activation in working memory areas, in comparison with low-anxious participants. The high-anxious group also showed extensive reductions in sustained activation of "default-network" areas (possible deactivation). After the negative video,the low-anxiety group shifted their activation dynamics in cognitive control regions to resemble those of the high-anxious group. These results suggest that reduced cognitive control in anxiety might be due to a transient, rather than sustained, pattern of working memory recruitment.

Defensive high-anxious individuals with chronic back pain demonstrate different treatment choices and patient persistence

The aim of this study is to determine whether the experience of, and response to chronic back pain was different for defensive high-anxious individuals than other personality types (defensive high-anxious, high-anxious, repressor and low-anxious). Participants (n = 111) were recruited from a heterogeneous sample of individuals who had reported back pain within the last 6 months. Self-report measures of trait anxiety and defensiveness were used to determine personality type. In addition, pain, treatment history, disability, depression and satisfaction with treatment were recorded. Despite reporting similar levels of pain to other personality groups, defensive high-anxious individuals reported significantly greater disability and depression (p < 0.01). Of the defensive high-anxious individuals, 92% sought more than one intervention. In comparison, repressors predominantly self-managed their pain with only 10% utilising more than one intervention. Surprisingly, there were no differences in treatment satisfaction between the four groups. The present study suggests that personality type is an important factor influencing patients’ treatment options, with defensive high anxious individuals substantially more likely to seek multiple interventions and remain within the care system. The present study provides a basis for future research into the role of personality type in the management of chronic pain.
