Memory Retrieval After an Acute Academic Stressor: An Exploratory Analysis of Anticipatory Cortisol and DHEA Responses
The relationship between hormonal reactivity to acute stress and memory is well established, but the role of anticipatory cortisol and dehydroepiandrosterone (DHEA) levels remains underexplored. This study aimed to assess the psychobiological responses (anxiety, affect, cortisol and DHEA) to an acad...

| Sumario: | The relationship between hormonal reactivity to acute stress and memory is well established, but the role of anticipatory cortisol and dehydroepiandrosterone (DHEA) levels remains underexplored. This study aimed to assess the psychobiological responses (anxiety, affect, cortisol and DHEA) to an academic examination, subsequent memory performance and associations between anticipatory hormonal response and memory retrieval. Seventy-nine undergraduates (10 males) completed an acquisition session involving picture encoding and immediate free recall. Forty-eight hours later, during the recall session, they sat a written examination followed by delayed free recall and recognition tasks. Results showed higher anticipatory anxiety, negative affect and cortisol levels in the recall session than in the acquisition session. Participants showed poorer delayed recall performance and reduced recognition of neutral pictures. In addition, after correction for multiple comparisons, exploratory hierarchical regression analyses indicated that anticipatory cortisol levels and the cortisol/DHEA ratio assessed prior to the recall session were negatively associated with total delayed free recall performance, with the cortisol/DHEA ratio also being negatively associated with delayed free recall of negative pictures. In the absence of a control group, these findings cannot be used to make causal inferences. However, they are consistent with theoretical accounts of DHEA's anti-glucocorticoid role and highlight associations between cortisol/DHEA balance and delayed free recall performance, particularly for negative emotional material. |
