Item Anticipated psychosocial stress informs sustained attention performance: A behavioral and physiological perspective(Southern New Hampshire University, 2021-04-07) Brau, Julia M.; Fortenbaugh, Francesca C.; Esterman, Michael; Corbo, VincentThe ability to sustain attention is paramount to the completion of daily activities, such as driving or attending to a lecture. Previous studies have suggested that stress prior to cognitive testing leads to changes in attentional performance based on stressor context, but the impact of anticipated stress on attention remains unclear. To answer this question, the current study examined a sample of thirty-one undergraduate students (age 18-35, M=21.5, S.D.=3.1) who either anticipated a psychosocial stressor or completed guided meditation before completing a go/no-go sustained attention task (gradCPT). Subjective measures of anxiety, self-esteem, extraversion, and neuroticism were also gathered along with heart rate and electrodermal activity measures to objectively determine stress reactivity. Correlational analyses revealed negative associations between state anxiety and commission errors (r=-0.5, p=0.048), reaction time variability (r=-0.522, p=0.038), and a positive association between state anxiety and accuracy (d’) (r=0.521, p=0.038) in the stress condition exclusively. When controlling for state anxiety, mixed design ANOVAs revealed a significant main effect of condition on d’ (F(1,28)=5.54, p=0.026), where the stress group showed lower d’. Further, data showed a trend of an interaction on reaction time variability (F(1,28)=3.49, p=0.072) where increased variability across the task duration occurred as a function of condition assignment, and a trend of a main effect of condition (F(1,28)=3.93, p=0.057) suggesting more commission errors under stress. The results suggest that anticipation of a stressor does impact sustained attention, but that performance may exist on a spectrum based on subjective appraisal of the stressor.

This study aims to reflect these findings using the Adverse Childhood Events Questionnaire (ACE-Q) to measure trauma, Psychological Maltreatment Review (PMR) to measure attachment, and the Self- Report Antisocial Behavior Measure (SABM) to measure antisocial tendencies. The hypothesis is that Childhood trauma and Parental Attachment will significantly predict variance in Adult Antisocial Behavior. Findings did not support the hypothesis, although there were findings that allude to a variance in antisocial behavior dependent on the relationship with the father, versus the mother.

Specifically, the opportunity cost theory predicts that changes in motivation may insulate cognitive resources and minimize mindwandering tendencies (Esterman & Rothlein, 2019). A recent study (Brosowsky et al., 2020) expanded on this theory using a rhythmic response task, further providing evidence that, over time on task, motivation and mind-wandering are negatively associated. Since motivation levels and changes in motivation may differ, the current study extends these findings by classifying subsamples of participants based on motivational differences to examine changes in performance. Using area under the curve (AUC) calculations (Pruessner, et al., 2003), such as AUCg (the overall change over time) and AUCi (the magnitude of change over time), overall motivation and the magnitude of change in motivation was calculated. A k-means cluster classification analysis was then used to create artificial groups based on both AUC values. This allowed for the investigation of differences in task performance and mind-wandering based on these groupings. Mixed design ANOVA analyses yielded a significant Block x AUCg motivation interaction effect on omission rate (F(3,441) = 3.979, p = 0.01) and a trend for a main effect of group (F(1,147) = 3.395, p = 0.07) on task variability. These main findings provide evidence that individuals with higher overall motivation may not experience performance deficits to the same degree that those with low motivation appear to. Further, the magnitude of change in motivation may only exhibit differences regarding mind-wandering tendencies.

Further, research has shown that people with high anxiety tend to focus more on threats, are more critical of information, and worry more about political issues (Caporino et al., 2020; Marcus & Mackuen, 1993; Mogg et al., 1994), delineating the need to explore anxiety in interpretation of political imagery. The current study examines anxiety as an extension of a previous study that investigates the psychological and physiological reactions to political images. In a sample of thirty-one undergraduate students, we collected demographic and anxiety variables through self-report prior to completion of a political propaganda task. Task stimuli consisted of liberal and conservative images with and without text. K-means cluster classification analyses were conducted to determine groups of high (N=11) and low (N=20) trait anxiety individuals. Mixed design ANOVAs revealed a significant three-way interaction (text*political alignment*anxiety) on image rating, F(1,29)=4.443, p=0.044, where high anxiety individuals rate conservative images without text more positively than liberal images without text. Similarly, these individuals rate liberal images with text more positively than conservative images with text. Further, data revealed a trend for a threeway interaction (text*political alignment*anxiety) on reaction time, F(1,29)=3.659, p=0.066, where individuals with low anxiety have a longer reaction time to conservative images with text. These results suggest that anxiety plays an integral role in the reactions to political imagery along with the political alignment and inclusion of text within the images. (Author abstract)
