Divided attention at encoding or retrieval interferes with emotionally enhanced memory for words.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Memory Research

Background:

• Emotional information is generally better remembered than neutral information.
• The impact of divided attention on memory for emotional content is not fully understood.

Purpose of the Study:

• To investigate whether emotional words are less vulnerable than neutral words to the effects of divided attention.
• To examine the influence of divided attention during encoding and retrieval on memory for emotional valence.

Main Methods:

• Two experiments were conducted with undergraduate students encoding words of varying valence and arousal.
• Experiment 1 involved divided attention (DA) during encoding, while Experiment 2 manipulated attention during retrieval.
• Memory was assessed using free recall after a filled delay.

Main Results:

• Full attention at encoding enhanced recall for negative words compared to neutral words.
• Divided attention at encoding or retrieval impaired recall across all valences.
• Divided attention eliminated the memory benefit for negative emotional information, making recall similar to neutral words.
• Memory for positive words did not differ significantly from neutral words in either condition.

Conclusions:

• Divided attention during encoding or retrieval interferes with the mechanisms that typically enhance memory for negative emotional information.
• The memory advantage for negative emotional stimuli is susceptible to attentional limitations.
