Transfer of negative valence in an episodic memory task

Area of Science:

• Cognitive Psychology
• Neuroscience
• Affective Science

Background:

• Emotion significantly impacts perception and memory.
• Negative emotion is known to impair associative memory.
• Emotion can also bias attitudes and preferences, causing a 'transfer of valence' effect.

Purpose of the Study:

• To investigate the relationship between negative emotion's impact on associative memory and the transfer of valence effect.
• To determine the conditions under which these two emotional effects on memory co-occur.

Main Methods:

• Multiple experiments were conducted using an associative memory paradigm.
• Participants were exposed to item-item pairings with negative or neutral stimuli.
• Subsequent memory recall and preference ratings were assessed.

Main Results:

• Negative emotion impaired associative memory for item-item pairings, consistent with prior research.
• A transfer of valence effect was observed, with items paired with negative stimuli rated less pleasant.
• The transfer of valence effect was found to be dependent on episodic memory.

Conclusions:

• Negative emotion has complex and multifaceted effects on memory.
• The transfer of valence effect is contingent upon the integrity of episodic memory.
• Findings link impairments in associative memory with valence transfer under negative emotional conditions.
