The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson
The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson
Electronic Theses and Dissertations
Acute stress is commonly experienced by many throughout their lives. Given the demanding lifestyle of many career paths, it's important to gauge the influence of these stressors upon cognitive performance. The present dissertation focus' upon explicit learning in attempts to explore one avenue of the stress-cognition relationship. The Trier Social Stress Test (TSST) was used as a lab stressor for Experiments 1 and 2, in which participants are asked to give a speech and complete a difficult math task in front of 2 evaluators trained to monitor non-verbal behavior. Experiment 1 investigates the dynamic stress response during the minutes following …
An Investigation On The Effects Of Virtual Social Support On Working Memory And Stress, Erin Perry
An Investigation On The Effects Of Virtual Social Support On Working Memory And Stress, Erin Perry
Honors College
Stress has a negative effect on day-to-day behavior and cognition. Face-to-face social interactions often induce feelings of social support, which works to counteract the negative effects of stress. However, it is unclear if virtual interactions offer the same benefits as face-to-face interactions. This study explores the relationship between perceived stress levels and their effect on perceived social support and working memory functioning. We also explored how mood is affected by stressful experiences. Participants engaged in a laboratory stressor, where participants submerged their hand in cold water, to elicit an appropriate stress response. After the stress task, participants engaged in a …

This research uses a novel integration paradigm to investigate whether target locations read in from long-term memory (LTM) differ from perceptually encoded inputs in spatial working-memory (SWM) with respect to systematic spatial error and/or noise, and whether SWM can simultaneously encompass both of these sources. Our results provide evidence for a composite representation of space in SWM derived from both perception and LTM, albeit with a loss in spatial precision of locations retrieved from LTM. More generally, the data support the concept of a spatial image in working memory and extend its potential sources to representations retrieved from LTM.

The chapter deals with a form of transient spatial representation referred to as a spatial image. Like a percept, it is externalized, scaled to the environment, and can appear in any direction about the observer. It transcends the concept of modality, as it can be based on inputs from the three spatial senses, from language, and from long-term memory. Evidence is presented that supports each of the claimed properties of the spatial image, showing that it is quite different from a visual image. Much of the evidence presented is based on spatial updating. A major concern is whether spatial images …

Spatial working memory can maintain representations from vision, hearing, and touch, representations referred to here as spatial images. The present experiment addressed whether spatial images from vision and hearing that are simultaneously present within working memory retain modality-specific tags or are amodal. Observers were presented with short sequences of targets varying in angular direction, with the targets in a given sequence being all auditory, all visual, or a sequential mixture of the two. On two thirds of the trials, one of the locations was repeated, and observers had to respond as quickly as possible when detecting this repetition. Ancillary detection …
