Working Memory

411
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Stress Research

Background:

  • Acute stress is known to impair cognitive functions, including working memory.
  • However, the specific impact of acute stress on working memory strategies remains poorly understood.
  • Investigating strategy use is crucial for a comprehensive understanding of stress effects on cognition.

Purpose of the Study:

  • To examine how acute stress influences the utilization of a systematic spatial working memory search strategy.
  • To determine if stress impacts the self-generation and execution of search strategies.

Main Methods:

  • Participants underwent the Trier Social Stress Test (TSST) or control conditions.
  • Spatial working memory strategy use was assessed using the CANTAB spatial working memory subtest.
  • Subjective and cortisol stress levels were measured to confirm stress induction.

Main Results:

  • The TSST successfully induced subjective and cortisol stress responses.
  • No significant differences were found in the use of systematic search strategies between stress and control groups.
  • No significant effect of stress was observed on working memory search errors.

Conclusions:

  • Acute stress does not appear to impair the self-initiation or implementation of systematic spatial working memory search strategies.
  • These findings suggest that working memory strategy use may be resilient to acute stress.
  • Further research could explore other types of cognitive strategies or stress paradigms.
