Encoding origin of the terminal asymmetry effect in recall

Area of Science:

• Cognitive Psychology
• Human Memory Research

Background:

• Previous research indicates memory recall is sensitive to cueing methods.
• A 'terminal asymmetry effect' (TAE) was observed where recall for later items in a series is biased.

Purpose of the Study:

• To investigate whether the terminal asymmetry effect (TAE) originates during memory encoding or retrieval.
• To determine the influence of presentation versus post-presentation factors on TAE.

Main Methods:

• Two experiments were conducted with a total of 100 participants.
• Participants viewed a series of pictures, with recall cued in different ways.
• Experimental conditions manipulated presentation and post-presentation factors.

Main Results:

• The terminal asymmetry effect (TAE) was significantly influenced by the conditions under which the picture series was presented.
• Post-presentation factors, such as how recall was cued after viewing, did not affect the TAE.
• This suggests the effect is established during the initial memory encoding phase.

Conclusions:

• The terminal asymmetry effect (TAE) appears to be established during the encoding of information, not solely at retrieval.
• Presentation conditions are critical in shaping memory recall biases for sequential information.
• Understanding encoding processes is key to explaining memory recall phenomena like TAE.
