Comparison Between The Effects Of Acute Physical And Psychosocial Stress On Feedback-Based Learning, Xiao Yang, Brittany Nackley, Bruce H. Friedman

Psychology Faculty Publications

Stress modulates feedback-based learning, a process that has been implicated in declining mental function in aging and mental disorders. While acute physical and psychosocial stressors have been used interchangeably in studies on feedback-based learning, the two types of stressors involve distinct physiological and psychological processes. Whether the two types of stressors differentially influence feedback processing remains unclear. The present study compared the effects of physical and psychosocial stressors on feedback-based learning. Ninety-six subjects (Mage = 19.11 years; 50 female) completed either a cold pressor task (CPT) or mental arithmetic task (MAT), as the physical or psychosocial stressor, while electrocardiography and …

Boring But Demanding: Using Secondary Tasks To Counter The Driver Vigilance Decrement For Partially Automated Driving, Scott Mishler, Jing Chen

Psychology Faculty Publications

Objective

We investigated secondary–task–based countermeasures to the vigilance decrement during a simulated partially automated driving (PAD) task, with the goal of understanding the underlying mechanism of the vigilance decrement and maintaining driver vigilance in PAD.

Background

Partial driving automation requires a human driver to monitor the roadway, but humans are notoriously bad at monitoring tasks over long periods of time, demonstrating the vigilance decrement in such tasks. The overload explanations of the vigilance decrement predict the decrement to be worse with added secondary tasks due to increased task demands and depleted attentional resources, whereas the underload explanations predict the vigilance …

Transient Signals And Inattentional Blindness In A Multi-Object Tracking Task, Dakota B. Palmer, Yusuke Yamani, Taylor L. Bobrow, Nicole D. Karpinsky, Dean J. Krusienski

Psychology Faculty Publications

Inattentional blindness is a failure to notice an unexpected event when attention is directed elsewhere. The current study examined participants' awareness of an unexpected object that maintained luminance contrast, switched the luminance once, or repetitively flashed. One hundred twenty participants performed a dynamic tracking task on a computer monitor for which they were instructed to count the number of movement deflections of an attended set of objects while ignoring other objects. On the critical trial, an unexpected cross that did not change its luminance (control condition), switched its luminance once (switch condition), or repetitively flashed (flash condition) traveled across the …

Eyes Wide Open: Pupil Size As A Proxy For Inhibition In The Masked-Priming Paradigm, Jason Geller, Mary L. Still, Alison L. Morris

Psychology Faculty Publications

A core assumption underlying competitive-network models of word recognition is that in order for a word to be recognized, the representations of competing orthographically similar words must be inhibited. This inhibitory mechanism is revealed in the masked-priming lexical-decision task (LDT) when responses to orthographically similar word prime-target pairs are slower than orthographically different word prime-target pairs (i.e., inhibitory priming). In English, however, behavioral evidence for inhibitory priming has been mixed. In the present study, we utilized a physiological correlate of cognitive effort never before used in the masked-priming LDT, pupil size, to replicate and extend behavioral demonstrations of inhibitory …

Caffeinated And Non-Caffeinated Alcohol Use And Indirect Aggression: The Impact Of Self-Regulation, Brynn E. Sheehan, Ashley N. Linden-Carmichael, Cathy Lau-Barraco

Psychology Faculty Publications

Research shows that heavier alcohol use is associated with physical aggression. Scant research has examined the way in which alcohol relates to other forms of aggression, such as indirect aggression (e.g., malicious humor, social exclusion). Given the possible negative consequences of indirect aggression and the limited evidence suggesting alcohol use can elicit indirectly aggressive responses, research is needed to further investigate the association between drinking behavior and indirect aggression. Additionally, specific alcoholic beverages, such as caffeinated alcoholic beverages (CABs; e.g., Red Bull and vodka), may potentiate aggression above the influence of typical use, and thus warrant examination with regard to …

The Gaze-Cueing Effect In The United States And Japan: Influence Of Cultural Differences In Cognitive Strategies On Control Of Attention, Saki Takao, Yusuke Yamani, Atsunori Ariga

Psychology Faculty Publications

The direction of seen gaze automatically and exogenously guides visual spatial attention, a phenomenon termed as the gaze-cueing effect. Although this effect arises when the duration of stimulus-onset asynchrony (SOA) between a non-predictive gaze cue and the target is relatively long, no empirical research examined the factors underlying this extended cueing effect. Two experiments compared the gaze-cueing effect at longer SOAs (700 ms) in Japanese and American participants. Cross-cultural studies on cognition suggest that Westerners tend to use a context-independent analytical strategy to process visual environments, whereas Asians use a context-dependent holistic approach. We hypothesized that Japanese participants would …

Mouse-Tracking Reveals When The Stroop Effect Happens., Sara Incera, Theresa A. Markis, Conor T. Mclennan

Psychology Faculty Publications

We examined the continuous dynamics of the Stroop task using mouse-tracking. Participants moved the computer mouse to indicate the color of words presented on the computer screen in both congruent (blue in blue font) and incongruent (blue in yellow font) conditions. Mouse-tracking data revealed significant differences in reaction times, spatial attraction, and velocity. In the Stroop effect, word reading and color processing influenced performance, but they did so differently: Word reading influenced the early part of the mouse trajectory, but color processing influenced later parts. The data provide important new information about the real time processing dynamics underlying the effect.

Investigating Intrinsic And Extrinsic Variables During Simulated Internet Search, Molly M. Liechty, Poornima Madhaven

Psychology Faculty Publications

Using an eye tracker we examined decision-making processes during an internet search task. Twenty experienced homebuyers and twenty-five undergraduates from Old Dominion University viewed homes on a simulated real estate website. Several of the homes included physical properties that had the potential to negatively impact individual perceptions. These negative externalities were either easy to change (Level 1) or impossible to change (Level 2). Eye movements were analyzed to examine the relationship between participants' "stated preferences"[verbalized preferences], "revealed preferences" [actual decisions[, and experience. Dwell times, fixation durations/counts, and saccade counts/amplitudes were analyzed. Results revealed that experienced homebuyers demonstrated a more refined …

Individual Differences And The Impact Of Forward And Backward Causal Relations On The Online Processing Of Narratives, Stephen W. Briner, Christopher A. Kurby, Danielle S. Mcnamara

Psychology Faculty Publications

This paper investigated the impact of causality on reading time by examining the contributions of forward antecedent and backward consequence connections. Undergraduate students read four narrative texts, sentence by sentence. Reading times for each sentence were regressed onto the number of antecedents connecting forward to a sentence and backward to prior sentences. Overall, forward antecedents and backward consequences explained unique variance in reading times, with increases in antecedents and consequences predicting decreases in reading time. However, causal consequences did not contribute unique variance to participants with higher literature knowledge. Further, the presence of forward antecedents significantly attenuated reading time differences …

Dissociable Aspects Of Mental Workload: Examinations Of The P300 Erp Component And Performance Assessments, Carryl L. Baldwin, Joseph T. Coyne

Psychology Faculty Publications

Advanced technologies have enabled the choice of either visual or auditory formats for avionics and surface transportation displays. Methods of assessing the mental workload imposed by displays of different formats are critical to their successful implementation. Towards this end a series of investigations were conducted with the following aims: 1) developing analogous auditory and visual versions of a secondary task that could be used to compare display modalities; and 2) to compare the sensitivity of neurophysiological, behavioral and subjective indices of workload. Experiments 1 and 2 confirmed that analogous auditory and visual secondary oddball discrimination tasks were of equivalent difficulty …
