Executive attention moderates the effect of trait anxiety on hyperarousal symptoms

The majority of individuals exposed to trauma do not go on to develop posttraumatic stress disorder (PTSD); thus, researchers have sought to identify individual difference variables that make one particularly susceptible to posttraumatic stress symptoms. Trait anxiety is one individual difference variable implicated in the pathogenesis of posttraumatic stress symptoms. Following from cognitive theories of anxiety and extant data, the purpose of the present study was to examine executive attention as a moderator of the relation between trait anxiety and posttraumatic stress symptoms, particularly hyperarousal symptoms, among undergraduate women reporting trauma exposure (N = 88). As predicted, executive attention moderated the association between trait anxiety and hyperarousal symptoms, such that there was a significantly weaker relation as executive attention increased. Study results further support the potential buffering effect of executive attention in relation to posttraumatic stress symptoms, as well as the possible importance of targeting executive attention following trauma exposure.     

Attentional bias to threat: Roles of trait anxiety, stressful events, and awareness

Attentional biases for threat stimuli were assessed in high and low trait anxious subjects (n = 66) using a probe detection task. To examine the effects of trait anxiety and situational stressors, each subject was tested three times: Under no stress, laboratory-induced stress, and examination-induced stress. To evaluate the role of awareness, half the word stimuli were presented very briefly (14 msec) and masked, and the other half were presented for 500 msec without a mask. Results showed that high trait anxious subjects under exam stress showed an attentional bias towards unmasked threat stimuli compared with low trait subjects. This effect was not found under lab-induced stress, suggesting that the attentional bias for unmasked threat in high trait subjects may be a function of a prolonged stressor, rather than a transient increase in state anxiety. The results from the masked exposure condition were not predicted; high trait anxious subjects shifted attention towards the spatial location of threat words despite lack of awareness of their lexical content, but this bias was only apparent in the no-stress condition. The results are discussed in relation to recent cognitive theories of anxiety.     

Hassles,anxiety, and negative well-being

Adult volunteers (N = 234) responded to a “decontaminated” hassles scale plus measures of trait anxiety, perceived stress, psychiatric symptomatology, and minor physical ailments. All but the anxiety scale were time-referenced to the past month. Major findings were as follows: (1) Hassles and trait anxiety contributed positively to perceived stress, both individually and interactively, accounting altogether for 55% of the variance; highly anxious subjects showed lower increments in perceived stress with increasing hassles-exposure than did low anxious subjects. (2) Hassles and trait anxiety had a positive synergistic effect on psychiatric symptomatology which, along with the nonsignificant marginal main effects, accounted for 64% of the variance. (3) Hassles and trait anxiety had a positive synergistic effect on minor physical ailments in men; however, highly anxious women, who showed very high levels of illness under even low hassles-exposure, responded less to incremental stress than did low-anxious women. The significant Sex x Hassles x Trait-Anxiety interaction effect and all the implicated lower-order effects jointly accounted for 22% of the variance in minor ailments.     

Separation,self‐disclosure,and social evaluation anxiety as facets of trait social anxiety

In the current article, we propose an expansion of the trait anxiety concept to include interpersonal or social facets of trait anxiety involving separation from significant others and disclosing aspects of the self to others, as a supplement to the existing focus on social evaluation anxiety. Participants in three studies completed a modified version of the Endler Multidimensional Anxiety Scales that included a measure of trait social evaluation anxiety, as well as new measures of trait separation anxiety and trait self‐disclosure anxiety (i.e., three measures of trait social anxiety). Results showed that the social evaluation, separation, and self‐disclosure trait anxiety scales have strong psychometric properties and that they represent distinct but related components of trait anxiety. With respect to validity, the facets of trait social anxiety were predictive of related variables including self‐concealment, anxiety sensitivity, and trait worry. The theoretical and practical implications of a multifaceted approach to trait social anxiety are discussed in terms of an expanded multidimensional interaction model of anxiety.

Parental control, trait anxiety, and satisfaction with life in college students

Research on developmental psychopathology has highlighted the role of parental behavior in subsequent development of pathology in children and adolescents. Although parental psychological control has been an area of interest to researchers, the connection between psychological control and anxiety has not been well established. We administered measures of perceived parental control and acceptance (separate forms for mother and father), trait anxiety, and satisfaction with life to 202 undergraduate students. Analysis indicated that perception of parents (both mother and father) as psychologically controlling was significantly positively correlated with trait anxiety and significantly negatively correlated with satisfaction with life. This held even after the effects of psychological control by the other parent were statistically eliminated.     

特质焦虑初中生使用减弱调节策略的效果:一项ERP研究

采用情绪反应性-调节图片任务,考察特质焦虑青少年在下调负性情绪反应时的神经生理变化。结果发现,从行为学数据上看,两组被试都能达到下调目标,但低特质焦虑组的调节能力较强。从脑电数据上看,在刺激呈现之后300-600ms,高特质焦虑被试在负性情绪减弱调节效应方面显著小于低特质焦虑被试。在600-1000ms,高特质焦虑被试产生的LPP显著大于低特质焦虑被试。在1000ms以后,两组被试不存在显著差异。这就表明,我国高特质焦虑青少年对情绪反应有意调节能力总体较好,但较低特质焦虑青少年而言可能存在一定滞后性。     

Relationships between locus of control, trait anxiety, and state anxiety: an interactionist perspective.

This study examined the relationships among generalized expectancy for internal or external control, situational expectancy of control over aversive stimuli, trait anxiety level, and state anxiety reactivity. Seventy-two male subjects, selected from the upper and lower halves of the distributions of scores from the I-E and STAI A-Trait Scales, were randomly assigned to one of three conditions of expectancy of control over electric shock. Repeated measures of state anxiety were taken at three points in the experiment, and subjects were asked to rate the degree of control they expected to have in avoiding shocks. Results, based upon analyses of variance, were interpreted as strongly supportive of the use of the interactionist model in understanding the manner in which personality trait and situational variables interact in the determination of subject expectancies of control and anxiety reactivity.     

Fear of fear,trait anxiety and aerobic fitness in relation to state anxiety during adrenalin provocation

Abstract

Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety.     

Anxiety and the selective processing of emotional information: mediating roles of awareness, trait and state variables, and personal relevance of stimulus materials.

Previous research has established that anxiety patients demonstrate a cognitive bias that selectively favours the processing of threat related information. The current experiment employs a variant of a well established colour naming paradigm to address three issues concerning the nature of this anxiety linked pattern of selective processing. First, by considering non-clinical subjects and employing an experimental design capable of dissociating the influence of state and trait anxiety, the current study addresses the hypothesis that state anxiety elevations will elicit differential patterns of selectivity in high and low trait anxious subjects. Second, by presenting stimulus materials within or outside awareness, the study addresses the hypothesis that these processing biases occur automatically, without requiring the use of consciously mediated strategies. Third, by including both emotionally valenced stimulus materials which are related to, and which are unrelated to, the particular source of stress experienced by the subjects, the experiment addresses the hypothesis that such anxiety linked processing biases will be restricted to materials falling within the domain of current personal concern. The results of the present study clearly demonstrate that these three issues are not independent. Fundamentally different patterns of anxiety linked selective processing were observed when stimuli were presented outside awareness, permitting only automatic cognitive processing, and when stimuli were presented within awareness, permitting the use of consciously mediated strategies. The relative roles played by state and trait variables, and the degree to which these effects were influenced by the personal relevance of the stimulus materials, differed in each case. The implications of these findings for future research in this field are discussed.     

Trait anxiety, trait depression, worry, and memory

A study is reported which investigated the proposal that high trait anxiety is associated with a memory bias for worry themes. Forty-five participants were categorised as being high or low trait anxious on the basis of scores on the (Spielberger et al., 1983) (Manual for the State-Trait Anxiety Inventory (Form Y) (1983)). The participants were requested to rate a number of worry and non-worry statements for how much they generally thought about the issues represented by them. Analysis of the ratings given by the participants showed that low trait anxiety individuals thought about the non-worry items significantly more than worry items. The high trait anxiety participants, however, showed little or no difference in the amount of time spent thinking about worry and non-worry themes. In a subsequent free recall task of the statements it was observed that the low trait anxiety group recalled significantly more non-worry than worry items, whereas there was no such difference for the high trait group. It was also found that the degree of memory bias was related to both positive affectivity and trait anxiety. The implications of such findings are discussed.     

Motor performance under three levels of trait anxiety and stress

In general, the interactive effects of trait anxiety and stress on motor performance have been neglected in assessing the viability of the inverted-U hypothesis. The present investigation tested the inverted-U hypothesis using three levels of trait anxiety and psychological stress. Performance results produced an inverted-U curve for the three levels of stress, with subjects in the moderate-stress condition displaying the highest performance. In addition, a significant trait anxiety x stress interaction indicated that high trait-anxious subjects performed best in the low-stress condition, while low trait-anxious subjects performed best in the high-stressed condition. The discussion concerns theories attempting to explain the relationship between anxiety and motor performance.     

Detecting state and trait anxiety from auditory and visual cues: a meta-analysis

Observers' ability to detect state anxiety and trait anxiety in others was evaluated in a meta-analysis that also included a critical moderator variable, communication channel. The overall effect size (r) for accuracy was .39 for the 46 state anxiety studies and .26 for the 34 trait anxiety studies. However, the effect of communication channel was very substantial in magnitude and highly significant; it also interacted with the type of anxiety. State anxiety was correctly identified more often from audio-only stimuli (M r = .49) compared with video-only cues (r = .24), whereas the opposite was true for trait anxiety, where video-only cues resulted in greater accuracy (r = .31) compared with audio-only stimuli (r = .05). Results indicated that the moment-to-moment change in emotion (state anxiety) may be better communicated with vocal/verbal stimuli, whereas more stable features of personality (trait anxiety) may be more apparent from body and facial cues.     

Effects of trait and situational self-handicapping on competitive anxiety among athletes

Initial evidence suggests that the employment of self-handicapping strategies has a beneficial effect on negative affective states associated with the perceived threat of evaluative contexts (Harris & Snyder, 1986; Leary, 1986). The present study sought to describe the type of self-handicapping behaviors demonstrated by youth athletes (N=238) as well as to assess the stress-buffering role of athlete self-handicapping on indices of competitive state anxiety. Specifically, it was hypothesized that among high trait-handicapping athletes, those who report a greater degree of performance-debilitating obstacles prior to competition would demonstrate lowered cognitive and somatic state anxiety as well as greater state self-confidence than nonhandicapping athletes. However, MANOVA results indicated that both high trait and situational self-handicappers demonstrate elevated state anxiety immediately prior to competition. Results are discussed in relation to the possible role of state anxiety as a salient self-handicapping strategy within competitive sport.

Analysis of the effect of competitive trait anxiety on performance in Taekwondo competition.

This study examined the effect of competitive trait anxiety on performance in open- (sparring) and closed- (forms) skills in Taekwondo. 58 subjects responded to the Sports Competition Anxiety Test immediately prior to competition. Subjects were categorized into groups showing high, medium, and low competitive anxiety to assess whether differences on the variables of sparring and forms were significantly related with scores on competition anxiety, age, or gender after adjusting for the covariate of years of competition. Multivariate analysis of covariance showed no significant differences between subjects and the normative samples on competitive anxiety scores except for boys, whose scores were significantly higher than those of a normative sample of male youth athletes.     

Self-reported emotional disturbance and its relation to electrodermal reactivity,defensiveness and trait anxiety

The discordance between an electrodermal and a subjective measure of disturbance was studied in 36 males. Electrodermal responses to emotionally loaded questions were recorded and subjects were requested to rate on visual analogue scales how disturbing they found the questions. The subjects were divided into three groups according to their ‘accuracy’ of self-perception and it was hypothesised that those who reported low subjective disturbance but reacted relatively strongly electrodermally (‘repressors’), would have a high defensiveness score but low trait anxiety. Conversely, subjects who amplify their disturbance (‘sensitisers’) were expected to have a low defensiveness score and high trait anxiety. The hypotheses were confirmed suggesting that both under and over reporting of subjective disturbance are related to defensiveness and trait anxiety. Another finding was that ‘sensitisers’ were significantly younger than ‘repressors’.     

Arousal seeking as a moderator of life stress

This study investigated the relationship between life stress and measures of anxiety, depression, and hostility as a function of subjects' arousal-seeking status. Results indicated significant relationships between negative life change and measures of both anxiety and hostility. These relationships, however, held only for subjects who were low on the arousal-seeking dimension. The results suggest that arousal-seeking status may serve as a moderator variable in determining the relationship between life stress and other variables.     

Predictors of suicide attempts: state and trait components

The authors examined the state and trait components of 3 predictors of suicide attempts (depression, hopelessness, and anxiety), and their relationship to suicidal behavior. Self-report questionnaire and interview data from 180 adolescents enrolled in a prospective naturalistic study were analyzed. Between 23% and 30% of the variance in the predictors was attributable to subjects' trait levels of these variables; the trait, as well as the state, components of the predictor variables were interrelated; and trait levels of these variables were consistently related to suicide attempts. To reduce long-term risk of suicide attempts, clinicians should focus not only on reducing short-term distress but also on reducing individuals' more enduring patterns (trait levels) of negative affectivity.     

Vulnerability to false memory: The effects of stress, imagery, trait anxiety, and depression

There is now abundant evidence that false memories can be created inside and outside the laboratory, and much is known about the kinds of techniques and manipulations that encourage the creation of false memories. However, rather less is known about the influence of naturally occurring variables over which the experimenter or clinician has little or no control. The current study investigated the influence of some of these variables on false memory creation. The influence of individual differences in depression, trait anxiety, imagery vividness and the interaction of these factors with stress was studied. Subjects studied series of pictures and words and then attempted to recall all the pictures presented, at a low-stress time and then later at a high-stress time. Intrusions from words at recall were the false memories in this study. Subjects who experience more vivid imagery were more vulnerable to false memories when they were stressed. Low trait anxious subjects were more likely to assign remember judgement to a false memory when they were stressed. These findings are discussed in terms of the source monitoring framework and implications for clinical practice.
