Effect of negative emotion on prospective memory and its different components

Area of Science:

• Cognitive Psychology
• Social Cognition
• Neuroscience

Background:

• Prospective memory (PM) is crucial for daily functioning and social cognition.
• PM performance is vulnerable to emotional states, particularly negative emotions.
• PM is categorized into focal and non-focal types based on cue relevance to ongoing tasks.

Purpose of the Study:

• To investigate the impact of negative emotions on different types of prospective memory (focal vs. non-focal).
• To examine how negative emotions affect the prospective and retrospective components of PM.
• To determine if attentional resource allocation is influenced by negative emotions during PM tasks.

Main Methods:

• Experiment 1: 117 participants in a 2x2 between-subjects design (emotion: negative/neutral; cue focality: focal/non-focal).
• Experiment 2: 64 participants with enhanced difficulty in the retrospective component of non-focal PM.
• Utilized tasks to measure prospective memory performance and attentional load.

Main Results:

• Negative emotions significantly impaired both focal and non-focal prospective memory performance.
• Negative emotions occupied additional attentional resources.
• Both prospective and retrospective components of prospective memory were negatively affected by negative emotions, especially in non-focal tasks.

Conclusions:

• Negative emotions broadly impair prospective memory, irrespective of cue type (focal or non-focal).
• Attentional resources are significantly consumed by negative emotions, hindering cognitive processes.
• The detrimental effects of negative emotions extend to both the planning (prospective) and recall (retrospective) aspects of prospective memory.
