Acute Angiotensin II Receptor Blockade Facilitates Parahippocampal Processing During Memory Encoding in High-Trait-Anxious Individuals

BackgroundAngiotensin II receptor blockers (ARBs) have been associated with preventing posttraumatic stress disorder symptom development and improving memory. However, the underlying neural mechanisms are poorly understood. This study investigated ARB effects on memory encoding and hippocampal functioning that have previously been implicated in posttraumatic stress disorder development. MethodsIn a double-blind randomized design, 40 high-trait-anxious participants (33 women) received the ARB losartan (50 mg) or placebo. At drug peak level, participants encoded images of animals and landscapes before undergoing functional magnetic resonance imaging, where they viewed the encoded familiar images and unseen novel images to be memorized and classified as animals/landscapes. Memory recognition was assessed 1 hour after functional magnetic resonance imaging. To analyze neural effects, whole-brain analysis, hippocampus region-of-interest analysis, and exploratory multivariate pattern similarity analysis were employed. ResultsARBs facilitated parahippocampal processing. In the whole-brain analysis, losartan enhanced brain activity for familiar images in the parahippocampal gyrus (PHC), anterior cingulate cortex, and caudate. For novel images, losartan enhanced brain activity in the PHC only. Pattern similarity analysis showed that losartan increased neural stability in the PHC when processing novel and familiar images. However, there were no drug effects on memory recognition or hippocampal activation. ConclusionsGiven that the hippocampus receives major input from the PHC, our findings suggest that ARBs may modulate higher-order visual processing through parahippocampal involvement, potentially preserving intact memory input. Future research needs to directly investigate whether this effect may underlie the preventive effects of ARBs in the development of posttraumatic stress disorder.

To err is human- to understand error-processing is divine: Contributions of working memory and anxiety to error-related brain and pupil responses.

Both anxiety and working memory capacity appear to predict increased (more negative) error-related negativity (ERN) amplitudes, despite being inversely related to one another. Until the interactive effects of these variables on the ERN are clarified, there may be challenges posed to our ability to use the ERN as an endophenotype for anxiety, as some have suggested. The compensatory error monitoring hypothesis suggests that high trait-anxiety individuals have larger ERN amplitudes because they must employ extra, compensatory efforts to override the working memory demands of their anxiety. Yet, to our knowledge, no ERN study has employed direct manipulation of working memory demands in conjunction with direct manipulations of induced (state) anxiety. Furthermore, little is known about how these manipulations affect other measures of error processing, such as the error-related pupil dilation response and post-error behavioral adjustments. Therefore, we manipulate working memory load and anxiety in a 2 × 2 within-subjects design to examine the interactive effects of working memory load and anxiety on ERN amplitude, error-related pupil dilation response amplitude, and post-error behavior. There were no effects of our manipulations on ERN amplitude, suggesting a strong interpretation of compensatory error-processing theory. However, our worry manipulation affected post-error behavior, such that worry caused a reduction in post-error accuracy. Additionally, our working memory manipulation affected error-related PDR magnitude and the amplitude of the error-related positivity (Pe), such that increased working memory load decreased the amplitude of these responses. Implications of these results within the context of the compensatory error processing framework are discussed.

Anxiety-linked impairment in the ability to recode stimuli.

It has been proposed that elevated trait anxiety is associated with deficits in cognitive flexibility, which is required to enable people to switch between different ways of classifying information. Recent research has focused on a particular facet of cognitive flexibility that may be specifically impaired in high trait anxious individuals. This concerns the ability to recode stimulus information that has initially been categorized in terms of 1 stimulus dimension, in terms of an alternative dimension. However, limitations in previously employed assessment methodologies compromise the capacity to draw firm conclusions from prior research investigating this hypothesis. Across 2 studies we developed and delivered a novel stimulus information recoding assessment task to a sample of individuals who varied in trait anxiety, to test the hypothesis that elevated trait anxiety is specifically associated with a deficit in the ability to recode information that has already been classified. Across both studies we found evidence to support this hypothesis. The theoretical and practical implications of these findings are discussed.

High-trait anxious individuals show positive relationship between HRV and threat vigilance.

Selectively attending to threat-related stimuli in the environment, known as threat bias (TB), is a prominent feature of anxiety. Individuals with high anxiety also tend to show lower heart rate variability (HRV), a reflection of reduced parasympathetic cardiac control. Previous investigations have established associations between low HRV and various attentional processes that facilitate attention to threat, though these have primarily been conducted among non-anxious individuals. The current analysis, derived from a larger TB modification study, examined the relationship between TB and HRV among a young, nonclinical sample of individuals with either high or low trait anxiety (HTA, LTA, respectively; Mage =25.8, SD=13.2, 61.3% female). Consistent with expectations, HTA (β=-.18, p=.087) trended toward an association with higher threat vigilance. A significant moderation effect showed the relationship between HRV and threat vigilance was influenced by TA (β=.42, p=.004). Simple slopes analysis revealed that for the LTA group, lower HRV trended toward higher threat vigilance (p=.123), consistent with expectations. However, this relationship was unexpectedly reversed for the HTA group, for whom higher HRV was a significant predictor of higher threat vigilance (p=.015). These results are interpreted within a cognitive control framework, in which regulatory ability, as assessed via HRV, may influence which cognitive strategy is employed when encountering threatening stimuli. Results suggest that HTA individuals with greater regulatory ability may employ a contrast avoidance mechanism, while those with reduced regulatory ability engage in cognitive avoidance.

The effect of trait anxiety on the time course of self-relevant processing: Evidence from the perceptual matching task

Studies have widely reported that trait anxiety is associated with a range of cognitive biases toward external negative emotional stimuli. However, few studies have examined whether trait anxiety modulates intrinsic self-relevant processing. This study investigated the electrophysiological mechanism underlying trait anxiety’s modulating effect on self-relevant processing. Event-related potentials (ERPs) were recorded while participants performed a perceptual matching task that assigned an arbitrary geometric shape to an association with a “self” or “non-self” label. Results showed larger N1 amplitudes under self-association than under friend-association conditions, and smaller P2 amplitudes for self- than for stranger-association conditions in individuals with high trait anxiety. However, these self-biases in the N1 and P2 stages were not observed in those with low trait anxiety until the later N2 stage, in which the self-association condition provoked smaller N2 amplitudes than the stranger-association condition. In addition, both high and low trait anxiety individuals showed larger P3 amplitudes for the self-association condition than for the friend- and stranger-association conditions. These findings suggest that, although both high and low trait anxiety individuals showed self-bias, high trait anxiety individuals distinguished between self-relevant and non-self-relevant stimuli at an earlier stage, which may reflect hypervigilance to self-relevant stimuli.

Trait anxiety is related to an impaired attention model for controllable threat cues: Evidence from ERPs

Attentional bias to threat cues is maladaptive for individuals with high trait anxiety (HTA), but may become adaptive when the dangers signaled by these cues can be controlled by timely actions. However, it remains unclear how HTA individuals allocate attention to controllable threat cues. The current study examined whether trait anxiety is associated with an impaired attention model for controllable threat cues and explored the related underlying neural mechanisms. A sample of 21 participants with low trait anxiety (LTA) and 21 with HTA completed a modified cued anticipation task which allowed participants to control the appearance of threatening pictures associated with controllable threat cues. Results revealed that HTA individuals had no difference in N1 amplitude among controllable threat cues, uncontrollable threat cues, and neutral cues, while LTA individuals showed the greatest N1 amplitude on controllable cues. HTA individuals also exhibited lower N2 amplitude than LTA individuals. The current study provides electrophysiological evidence showing that HTA individuals have impaired attention for processing controllable threat cues and weak inhibitory control. Deficient attention to controllable threat cues may be crucial in the mechanisms underlying trait anxiety.

The questionable validity of attention bias variability: Evidence from two conceptually unrelated cognitive tasks.

Attention bias variability is thought to measure fluctuations in attention towards and away from threat-related information and is elevated in affective disorders. However, recent evidence suggests that attention bias variability may quantify general reaction time variability rather than attention bias behavior per se. The current study calculated "attention bias variability" from two conceptually unrelated cognitive tasks: the dot-probe task (measuring attentional bias) and the arrow flanker task (measuring cognitive control). Attention bias variability measures were correlated across these unrelated tasks. Yet, when general reaction time variability was controlled, attention bias variability across tasks was no longer correlated. In addition, the reliability of attention bias variability measures decreased when controlling for general reaction time variability. Finally, although attention bias variability calculated from the dot-probe task initially correlated with anxious symptoms, this association was no longer significant when controlling for general reaction time variability. Our sample was comprised of high trait anxious individuals. Replication in clinical samples is warranted. These findings collectively provide strong empirical evidence that attention bias variability is not a valid measure of attention-related behavior, but reflective of general reaction time variability more broadly.

Reducing anxiety and attentional bias with reward association learning and attentional bias modification.

The current study examined the effects of a reward associative learning procedure and the traditional threat-avoidance ABM paradigm on anxiety and attentional bias. In reward training, participants were given high rewards for correct responses to neutral target and low rewards for correct responses to negative target. In reward control training, participants received no cues of rewards after their responses. High trait anxious individuals (N = 76) first completed a session of reward training or reward control training, followed by four sessions of ABM training or ABM control training. Generalized anxiety disorder symptom (GAD-7) and attentional bias in a dot-probe task were assessed during pre-and post-training. Results indicated that the effect of ABM training on reducing anxiety was only obtained in the reward training condition. Participants who received reward training showed significantly less attentional bias compared with those receiving reward control training. There was no significant training effect of ABM on atttentiona bias. Results suggested that reward training reduced general anxiety and attentional bias. Traditional ABM training reduced anxiety only when combined with reward training. Attentional bias in anxiety are modifiable through reward training.

Early Safety Discrimination Under Uncertainty in Trait Anxiety: An Event-Related Potential Study.

Detection of safety-threat signals during uncertainty is an important mechanism of developmental anxiety disorder (AD). Although extensive research has focused on the detection of uncertain threat signals in anxious individuals, relatively little attention has been given to the identification of safety signals during uncertainty, which is an important way to relieve anxiety in individuals with AD. To investigate this phenomenon, 16 subjects with high trait anxiety (HTA) and 16 with low trait anxiety (LTA) completed a modified cue-target task in certain and uncertain stimulus blocks. In the uncertain block, the cue was followed by a threat picture or safety picture in 20% of trials, respectively; in the certain block, the cue could be followed by a threat picture or a safety picture on 100% of trials. Behavioral responses and event-related potentials (ERPs) were recorded. The ERP results demonstrated that LTA participants exhibited larger P2 amplitudes in the detection of safety cues than of threat cues during the uncertain block, whereas HTA participants showed significant P2 amplitudes between the safety and threat cues during the certain block, impairing the detection of safety stimuli during uncertainty. However, all participants exhibited greater N2 amplitudes following threat cues in certainty or uncertainty conditions. These findings pertaining to the P2 amplitude suggested distinctive attentional biases between HTA and LTA individuals, whereas the N2 amplitude showed association learning in uncertain conditions, compensating for safety-threat detection in HTA individuals.

Increased Intra-Individual Variability as a Marker of Executive Dysfunction in Generalized Anxiety Disorder

Recent studies suggest that individual difference in intra-individual variability (IIV) of reaction times is an important indicator of attentional executive control. However, there are few existing studies on the executive control of high trait-anxious individuals assessed by using reaction time variability. This study assessed whether executive functions are impaired among clinical and non-clinical trait-anxious individuals indicated by IIV. The cross-reliability and discriminative power of three IIV parameters (raw intra-individual standard deviation, SD; reaction time coefficient of variation, RTCV; and mean absolute deviation, MAD) were compared. Twenty-five non-clinical individuals with low trait anxiety (LTA), 31 non-clinical individuals with high trait anxiety (HTA), and 19 clinical patients diagnosed with generalized anxiety disorder (GAD) finished self-reported measures, an emotional spatial-cuing task, and a non-emotional arrow flanker task. In the emotional task, GAD patients had significantly slower response speed, lower accuracy, and greater IIV parameters than the LTA and HTA groups. In the non-emotional task, the GAD group exhibited poorer processing efficiency, greater SD and RTCV, and intact performance effectiveness. RTCV is suggested to be a better marker of executive dysfunction than SD and MAD due to its good discriminative power and reliability as well as less affected by reaction times.

When the approaching threat is uncertain: Dynamics of defensive motivation and attention in trait anxiety.

Uncertainty of threat has been linked to anxiety, but little is known about how neurophysiological responses change as uncertain threats approach and whether trait anxiety modulates these changes. The current study was designed to explore aspects of the dynamics of defensive motivation (startle reflex elicited by acoustic startle probes), attention (probe N100 component of event-related potentials elicited by acoustic startle probes), and autonomic nervous system activity (heart rate) when the approaching threat was certain or uncertain in a variant of the threat probability task. Behavioral results showed that high-trait anxious individuals reported higher levels of anxiety than low-trait anxious individuals only under the uncertain threat condition. Electromyographic data showed that high-trait anxious individuals tended to produce a more pronounced startle reflex, especially when the uncertain threat was proximal. This pattern was not observed in low-trait anxious individuals. By examining early attention engagement through probe N100, we observed a similar pattern in relation to defensive motivation. Moreover, under the uncertain threat condition, high-trait anxious individuals yielded a greater deceleration of heart rate than low-trait anxious individuals. These results indicate a distinct modulation effect of trait anxiety in the dynamics of defensive motivation, attention, and the autonomic nervous system during the anticipation of uncertain threats.

The Computational and Neural Substrates of Ambiguity Avoidance in Anxiety.

Theoretical accounts have linked anxiety to intolerance of ambiguity. However, this relationship has not been well operationalized empirically. Here, we used computational and neuro-imaging methods to characterize anxiety-related differences in aversive decision-making under ambiguity and associated patterns of cortical activity. Adult human participants chose between two urns on each trial. The ratio of tokens (‘O’s and ‘X’s) in each urn determined probability of electrical stimulation receipt. A number above each urn indicated the magnitude of stimulation that would be received if a shock was delivered. On ambiguous trials, one of the two urns had tokens occluded. By varying the number of tokens occluded, we manipulated the extent of missing information. At higher levels of missing information, there is greater second order uncertainty, i.e., more uncertainty as to the probability of pulling a given type of token from the urn. Adult human participants demonstrated avoidance of ambiguous options which increased with level of missing information. Extent of ‘information-level dependent’ ambiguity aversion was significantly positively correlated with trait anxiety. Activity in both the dorsal anterior cingulate cortex and inferior frontal sulcus during the decision-making period increased as a function of missing information. Greater engagement of these regions, on high missing information trials, was observed when participants went on to select the ambiguous option; this was especially apparent in high trait anxious individuals. These findings are consistent with individuals vulnerable to anxiety requiring greater activation of frontal regions supporting rational decision-making to overcome a predisposition to engage in ambiguity avoidance at high levels of missing information.

No change in electrocortical measures of performance monitoring in high trait anxious individuals following multi-session attention bias modification training

Heightened attentional bias to threat and enhanced performance monitoring have been linked to higher levels of anxiety. Attentional bias modification (ABM) was developed to reduce attentional bias to threat and thus reduce anxiety. Previous studies have shown that ABM can change the activity in brain regions that are involved in cognitive control and threat detection, such as anterior cingulate cortex, which also plays a critical role in error monitoring and is the main source of the error-related negativity (ERN). While single session ABM has been shown to be effective in reducing attentional bias to threat and performance monitoring (i.e., ERN), the effect of multi-session ABM training on electrocortical measures of performance monitoring in high trait anxious individuals remains unknown. In the present study, we investigated whether multi-session ABM training would reduce the amplitude of the ERN. Individuals with high trait anxiety and attentional bias to threat were assigned in a counterbalanced order to an ABM training group (n = 26) or a control group (n = 25). Training lasted for 6 weeks with 36 training sessions delivered via cellphone. Before and after training, attentional bias was assessed with a visual dot-probe task and performance monitoring was measured with an arrow flanker task where the elicited ERN was collected. ABM training did not reduce ERN amplitudes. Bayesian analysis confirmed the null hypothesis of no changes in ERN amplitude following multi-session ABM. Therefore, our findings do not support the hypothesis that multi-session ABM training reduces performance monitoring processes in high trait anxious individuals. Our findings indicate that different methodological features of ABM training, such as the duration, location, and subject characteristics, may impact the efficacy of ABM on modulating performance monitoring. Identifying the ABM training parameters that impact performance monitoring processes should be further considered in future research.

Inhibition or Disinhibition? Creativity Relates to Better Flexible Inhibitory Control

Trait anxiety has been shown to moderate transcranial direct current stimulation (tDCS) effects on some cognitive functions. Based on the attentional control theory (ACT), trait anxiety might be closely related to dysfunctional executive control and prefrontal activity. Importantly, executive and prefrontal functions are necessary for creativity. Critically, it is unknown whether trait anxiety moderates tDCS effects on creativity. To address this, thirty low-trait-anxious (LTA) and thirty-one high-trait-anxious (HTA) participants performed creativity tasks assessing divergent thinking (alternate uses task, AUT) and convergent thinking (compound remote associates test, CRAT), while receiving three types of tDCS (L-R+: left cathodal/right anodal; L+R-: reverse protocol; sham) over the bilateral dorsolateral prefrontal cortex (DLPFC). L+R- stimulation promoted superior performance on the AUT compared with the other two stimulations. Importantly, L+R- stimulation benefitted LTA but not HTA individuals. No significant main nor interactive effects were found on the CRAT. These results demonstrate that L+R- stimulation benefits divergent but not convergent thinking. Furthermore, divergent thinking is more sensitive to L+R- stimulation in the LTA group than in the HTA group. Based on the ACT, this is likely due to differential DLPFC activation between the groups. Future studies should consider trait anxiety when exploring tDCS effects on creativity.

The Association between 5-Hydroxytryptamine Receptor 1B rs13212041 Polymorphism and Trait Anxiety in Chinese Han College Subjects.

Trait anxiety is a vulnerable personality factor for anxiety and depression. High levels of trait anxiety confer an elevated risk for the development of anxiety and other psychiatric disorders. There is evidence that 5-hydroxytryptamine receptor 1B (5-HT1B) gene polymorphisms play an important role in emotional disorders. Genotyping for four single-nucleotide polymorphisms (SNP) (rs11568817, rs130058, rs6297, and rs13212041) was conducted for 388 high trait anxious (HTA) individuals and 463 low traitanxious (LTA) individuals in Chinese Han college subjects. The results showed that the frequencies of the C-allele and TC + CC genotype of rs13212041 in the LTA individuals were higher than that in the HTA individuals (p = 0.025 and p = 0.014, respectively). Both the C-allele and TC + CC genotype were associated with trait anxiety decreasing (OR = 0.771 and OR = 0.71, respectively). Furthermore, different gene model analysis also showed that the C allele was a protective factor for trait anxiety in Chinese Han college subjects. These findings suggest that 5-HT1B rs13212014 may play a role in trait anxiety among China Han college subjects. The rs13212014 polymorphism may be involved in decreasing the risk of trait anxiety. These results also provide a novel insight into the molecular mechanism underlying trait anxiety.

Sex Differences in Anxiety: An Investigation of the Moderating Role of Sex in Performance Monitoring and Attentional Bias to Threat in High Trait Anxious Individuals.

Anxiety disorders are more predominant in women than men, however there is a lack of understanding as to what neurocognitive mechanisms drive this sex difference. Recent investigation has found a potential moderating role of sex in the relationship between anxiety and the error related negativity (ERN)—a component of error-monitoring that is prevalent in high anxiety individuals—such that females display a positive relationship between anxiety/worry and ERN amplitude. We strove to further explore the influence of sex on the relationship between trait anxiety and performance monitoring, specifically with ERN, as well as extend this work to include another hallmark of anxiety, attentional bias to threat. To meet this end, participants performed the flanker and dot-probe tasks, respectively. We did not find a significant difference in the relationship between attention bias scores and anxiety for female vs. males participants. Furthermore, ΔERN amplitudes were greater in males compared to females, and males had more positive CRN amplitudes than females. There were no significant associations between ERN or ΔERN with anxiety in both male and female participants. However, there was a significant relationship between CRN amplitudes and trait anxiety in male but not female participants. Given these results, the effect of sex on the relationship between components of performance monitoring—namely the CRN and ERN—and anxiety may be more nuanced than the current understanding. Our study was limited to detecting medium to large sized moderation effects. Our findings may be important for future meta-analysis on sex differences in anxiety.

Trait anxiety moderates the effects of tDCS over the dorsolateral prefrontal cortex (DLPFC) on creativity

Trait anxiety has been shown to moderate transcranial direct current stimulation (tDCS) effects on some cognitive functions. Based on the attentional control theory (ACT), trait anxiety might be closely related to dysfunctional executive control and prefrontal activity. Importantly, executive and prefrontal functions are necessary for creativity. Critically, it is unknown whether trait anxiety moderates tDCS effects on creativity. To address this, thirty low-trait-anxious (LTA) and thirty-one high-trait-anxious (HTA) participants performed creativity tasks assessing divergent thinking (alternate uses task, AUT) and convergent thinking (compound remote associates test, CRAT), while receiving three types of tDCS (L-R+: left cathodal/right anodal; L+R-: reverse protocol; sham) over the bilateral dorsolateral prefrontal cortex (DLPFC). L+R- stimulation promoted superior performance on the AUT compared with the other two stimulations. Importantly, L+R- stimulation benefitted LTA but not HTA individuals. No significant main nor interactive effects were found on the CRAT. These results demonstrate that L+R- stimulation benefits divergent but not convergent thinking. Furthermore, divergent thinking is more sensitive to L+R- stimulation in the LTA group than in the HTA group. Based on the ACT, this is likely due to differential DLPFC activation between the groups. Future studies should consider trait anxiety when exploring tDCS effects on creativity.

Trait anxiety is associated with reduced typicality asymmetry in fear generalization

In fear conditioning, training with typical category exemplars has been shown to promote fear generalization to novel exemplars of the same category, whereas training with atypical category exemplars supports limited if any generalization to other category members, amounting to a typicality asymmetry in fear generalization. The present study sought to examine how trait anxiety bears on typicality asymmetry in fear generalization. Participants in one condition were presented with typical exemplars during fear acquisition and atypical exemplars of the same category in the subsequent generalization test (typical condition), whereas in the other group, atypical and typical exemplars were presented during fear acquisition and generalization test, respectively (atypical condition). We observed a typicality asymmetry in fear generalization in self-reported expectancy ratings in low trait anxious individuals only. High trait anxious individuals showed a similar degree of fear generalization in both conditions. The current results help illuminate why some individuals are at risk for exhibiting broad fear generalization after exposure to an aversive event.

The Effects of Emotional Working Memory Training on Worry Symptoms and Error-Related Negativity of Individuals with High Trait Anxiety: A Randomized Controlled Study

Trait anxiety is characterized by impaired gating of threat from working memory (WM), allowing unnecessary maintenance of anxious cognitions. Improving filtering efficiency of threatening information through computerized WM training might reduce intrusive, worrisome thoughts. We randomized high-trait anxious individuals to 9 sessions of high-potency n-back (n = 19) or low-potency 1-back (n = 18) training to examine their effects on various neurocognitive indices of WM functioning and emotional symptoms. Following the interventions, multilevel modeling analyses revealed both training conditions resulted in significant improvements in attentional (Flanker), WM capacity (operation and spatial span tasks), and WM filtering efficiency (change detection task) measures, and increased N2 amplitudes. However, the high-potency training produced more favorable results at post-training, indexed by larger ERN amplitudes. We also observed significant reductions in trait anxiety and worry symptoms for the high-potency training following the intervention, although, low-potency training caught up at follow-up with comparably reduced symptoms. These results show that emotional WM training can improve neurocognitive processes of attention and WM as well as symptoms of worrying. Overall, this study encourages the development of a standalone or adjunctive cognitive intervention focused on WM for vulnerable populations with high trait anxiety or worry symptoms.

A brief positive psychological intervention prior to a potentially stressful task facilitates more challenge-like cardiovascular reactivity in high trait anxious individuals.

When confronted with stress, anxious individuals tend to evaluate the demands of an upcoming encounter as higher than the available resources, thus, indicating threat evaluations. Conversely, evaluating available resources as higher than the demands signals challenge. Both types of evaluations have been related to specific cardiovascular response patterns with higher cardiac output relative to peripheral resistance indicating challenge and higher peripheral resistance relative to cardiac output signaling threat. The aim of this research was to evaluate whether a brief positive psychological exercise (best possible selves intervention) prior to a potentially stress‐evoking task shifted the cardiovascular profile in trait anxious individuals from a threat to a challenge type. We randomly assigned 74 participants to either a best possible selves or a control exercise prior to performing a sing a song stress task and assessed their level of trait anxiety. Cardiac output (CO) and total peripheral resistance (TPR) were continuously recorded through baseline, preparation, stress task, and recovery, respectively, as well as self‐reported affect. Trait anxiety was related to higher CO in the best possible selves group and lower CO in the control group. While high trait anxious individuals in the control group showed increasing TPR reactivity, they exhibited a nonsignificant change in the best possible selves group. Moreover, in the latter group a stress‐related decrease in positive affect in high trait anxious participants was prevented. Findings suggest that concentrating on strengths and positive assets prior to a potentially stressful encounter could trigger a more adaptive coping in trait anxious individuals.
