A variety of studies have explored the effects of stress on short-term memory formation and recollection. The objective of this study was to examine the effect of physiological stress response on short term memory. Stress response was evaluated by measuring changes in respiration rate, electrodermal activity (EDA) and heart rate in response to an unanticipated stressor—the sounding of an air horn. Subsequently, researchers sought to observe the implication of this stress response on participant memorization of two lists of words. Participants were run in two trials. The first trial served as the control condition and no stressor was presented during word memorization or recall. During the second trial, the experimental condition, the stressor was presented before recall. It was hypothesized that an increase in physiological values from baseline values would decrease the number of words memorized. Results found that in every trial a stress response was elicited; that is, values in respiration rate, EDA and heart rate deviated from baseline data. However, the intensity of the stress response did not significantly affect memory test performance. Overall, this data suggested that no correlation can be made between the degree of physiological stress response and the success of short-term memory recall.
