Integrating personality, daily life events and emotion: Role of anxiety and positive affect in emotion regulation dynamics

We investigated the roles of anxiety and positive affect in emotion regulation, looking simultaneously at personality, daily life events, and affects. We hypothesized that individual differences in the temporal dynamics of affective experience related to trait anxiety would manifest themselves both in affective responsiveness to life events and in homeostatic regulatory forces. Data were collected from 49 adults, who rated their affective state three times a day over a 40-day period. Data were analyzed using a dynamical system model and graphical representations in the form of vector fields. Results showed that anxiety chiefly interacted with home base (attractor) positions as a function of life events. It also influenced the shape of positive affectivity trajectories in response to negative events.     

Comments concerning Iverach, et al., Screening for personality disorders among adults seeking speech treatment for stuttering [J. Fluency Disorders 34 (2009) 173-186

Iverach, Jones, O’Brian, Block, Lincoln, and Harrison (2009) indicate the high co-occurrence of one or more Personality Disorders (PD) for adults who stutter. The findings of Iverach et al. argue against many years of research and the experiences of skilled clinicians who have considered the relationship between stuttering and anxiety/negative affectivity. The results of Iverach et al. are questioned based on several methodological issues.Educational objectives: 1. To explain why the unusually high occurrence of personality disorders (PD) for individuals who stutter found by Iverach et al. (2009) may be questionable based on methodological approach. 2. To explain the heightened levels of anxiety experienced by many individuals who stutter as a natural and reasonable response to a chronic and serious problem such as stuttering. 3. To debate the potential for the inaccurate diagnosis of Axis II Personality Disorders to unnecessarily stigmatize individuals who stutter.     

To freeze or not to freeze? Affective and cognitive perturbations have markedly different effects on postural control

Similar effects have been reported for diverting attention from postural control and increased anxiety on the characteristics of center-of-pressure (COP) time series (decreased excursions and elevated mean power frequency). These effects have also received similar interpretations in terms of increased postural stiffness, suggesting that cognitive and affective manipulations have similar influences on postural control. The present experiment tested this hypothesis by comparing postural conditions involving manipulations of attention (diverting attention from posture using cognitive and motor dual tasks) and anxiety (standing at a height), and by complementing posturography with electromyographic analyses to directly examine neuromuscular stiffness control. Affective and cognitive manipulations had markedly different effects. Unlike the height condition, diverting attention from balance induced smaller COP amplitudes and higher sway frequencies. In addition, more regular COP trajectories (lower sample entropy) were found in the height condition than the dual-task conditions, suggesting elevated attentional investment in posture under the affective manipulation. Finally, based on an analysis of the cross-correlation function between anterior-posterior COP time series and enveloped calf muscle activity, indications of tighter anticipatory neuromuscular control of posture were found for the height condition only. Our data suggest that affective and cognitive perturbations have qualitatively different effects on postural control, and thus are likely to be associated with different control processes, as evidenced by differences in neuromuscular regulation and attentional investment in posture.     

Typical performance measures of emotion regulation and emotion perception and frontal EEG asymmetry in an emotional contagion paradigm

In order to replicate and extend previous observations of validity of the self-reported habitual regulation of one’s affect and the perception of other people’s emotions, prefrontal electroencephalographic (EEG) asymmetry was recorded during and after social-emotional stimulation. After stimulation with other people’s vocal expression of anxiety, individuals with lower scores on emotion regulation did not show recovery of asymmetry changes but even increased changes in the direction that had been adopted during the stimulation. Whether this was to the right or to the left depended on their scores on emotion perception. Participants high on perception showed the expected changes to the right during the anxiety stimulation (indicating increased withdrawal motivation) and to the left during the cheerfulness stimulation (indicating increased approach motivation), whereas individuals low on perception showed the opposite pattern. During the anxiety stimulation, participants low on perception only showed the unexpected change to the left if they were also low on regulation. Individual differences in regulation did not play a role when participants were confronted with other people’s laughter. The findings demonstrate the validity of the self-report measures by using EEG measures, and moreover support the usefulness of differentiated and process-oriented approaches in the field of trait emotional intelligence.     

Can Nervous Nelly negotiate? How anxiety causes negotiators to make low first offers,exit early,and earn less profit

Negotiations trigger anxiety. Across four studies, we demonstrate that anxiety is harmful to negotiator performance. In our experiments, we induced either anxiety or neutral feelings and studied behavior in negotiation and continuous shrinking-pie tasks. Compared to negotiators experiencing neutral feelings, negotiators who feel anxious expect lower outcomes, make lower first offers, respond more quickly to offers, exit bargaining situations earlier, and ultimately obtain worse outcomes. The relationship between anxiety and negotiator behavior is moderated by negotiator self-efficacy; high self-efficacy mitigates the harmful effects of anxiety.     

Emotional self-efficacy moderates anxiety-related impairments in math performance in elementary school-age youth

Excessive anxiety is associated with impairments in academic achievement. However, not all children with elevated anxiety share an equal risk for academic difficulty. The current study investigated whether individual differences in emotional self-efficacy - confidence in one’s ability to regulate negative emotions - protected against anxiety-related impairments in a standardized math exam in a sample of elementary school youth (N = 139). Results indicated that anxiety negatively predicted math test performance only for children with low levels of emotional self-efficacy. Students reporting high levels of emotional self-efficacy did not show anxiety-related decrements on the test performance. Emotional self-efficacy appears useful in managing negative effects of anxiety.     

Anxiety, a benefit and detriment to cognition: behavioral and magnetoencephalographic evidence from a mixed-saccade task

Anxiety is typically considered an impediment to cognition. We propose anxiety-related impairments in cognitive-behavioral performance are the consequences of enhanced stimulus-driven attention. Accordingly, reflexive, habitual behaviors that rely on stimulus-driven mechanisms should be facilitated in an anxious state, while novel, flexible behaviors that compete with the former should be impaired. To test these predictions, healthy adults (N=17) performed a mixed-saccade task, which pits habitual actions (pro-saccades) against atypical ones (anti-saccades), under anxiety-inducing threat of shock and safe conditions. Whole-head magnetoencephalography (MEG) captured oscillatory responses in the preparatory interval preceding target onset and saccade execution. Results showed threat-induced anxiety differentially impacted response times based on the type of saccade initiated, slowing anti-saccades but facilitating erroneous pro-saccades on anti-saccade trials. MEG source analyses revealed that successful suppression of reflexive pro-saccades and correct initiation of anti-saccades during threat was marked by increased theta power in right ventrolateral prefrontal cortical and midbrain regions (superior colliculi) implicated in stimulus-driven attention. Theta activity may delay stimulus-driven processes to enable generation of an anti-saccade. Moreover, compared to safety, threat reduced beta desynchronization in inferior parietal cortices during anti-saccade preparation but increased it during pro-saccade preparation. Differential effects in inferior parietal cortices indicate a greater readiness to execute anti-saccades during safety and to execute pro-saccades during threat. These findings suggest that, in an anxiety state, reduced cognitive-behavioral flexibility may stem from enhanced stimulus-driven attention, which may serve the adaptive function of optimizing threat detection.     

Anxiety and career exploration: Gender differences in the role of self-construal

Given the social nature of many tasks involved in exploring and committing to a career, we hypothesized that social anxiety would correlate to exploration and commitment, even after controlling for general anxiety. We also hypothesized that self-construal and gender would interact with social anxiety in relation to exploration and commitment. In a sample of predominantly European American undergraduates (n = 161), higher social anxiety associated with lower vocational commitment for both women and men, after accounting for general anxiety. For women, interdependence was also associated significantly with vocational commitment. Social anxiety correlated to environmental exploration only for men low in independence. Neither social anxiety nor self-construal associated with environmental exploration for women or foreclosure for either group.     

Perceived consequences underlying approach goals and avoidance goals in relation to anxiety

Numerous studies have examined anxiety from a cognitive and affective perspective but relatively little research has studied anxiety from a motivational perspective. There are theoretical grounds (e.g., Gray, 1982) for expecting anxiety to be characterised by heightened avoidance motivation, but this motivational bias is not thought to be accompanied by diminished approach motivation. A cross-sectional, mixed model design was used to investigate individuals’ response-variations on personal approach and avoidance goal systems. A convenience sample comprising an anxious group (n = 41) and non-anxious group (n = 33) completed tasks that measured number of self-generated approach goals and avoidance goals, and number of associated positive and negative consequence steps for goals. As predicted, anxious individuals, relative to non-anxious individuals, generated more avoidance goals and more negative consequence steps in response to goal non-attainment (irrespective of goal type) but did not differ on number of approach goals or positive consequence steps in response to goal attainment (irrespective of goal type). The present findings highlight the importance of personal goal systems in understanding the nature of anxiety.
