An experimental study on the self-reference effect

Area of Science:

• Cognitive Psychology
• Neuroscience
• Memory Studies

Background:

• The self-reference effect (SRE) demonstrates that information encoded in relation to oneself is better recalled.
• Previous research indicates self-referential encoding typically leads to superior memory performance compared to other encoding strategies, like semantic encoding.

Purpose of the Study:

• To investigate the impact of self-reference and other-reference encoding on recollective experience in recognition memory.
• To compare the self-reference effect in Chinese participants with findings from Western populations.

Main Methods:

• Three experiments utilized a between-subjects design with four encoding conditions: self-reference, mother-reference, reference to Lu Xun, and a semantic dimension (negative-positive).
• Participants rated personality traits under these conditions, followed by a recognition test where they distinguished between 'remember' (recollective experience) and 'know' (familiarity) responses.

Main Results:

• Both self-reference and mother-reference conditions resulted in the highest proportion of correct 'remember' responses and the lowest proportion of correct 'know' responses.
• In contrast to Western participants, Chinese participants showed no significant difference between self-reference and mother-reference conditions in terms of 'remember' and 'know' responses.

Conclusions:

• The findings suggest that cultural factors may influence the self-reference effect, as mother-reference yielded similar memory benefits to self-reference in Chinese participants.
• The results provide insights into the nature of recollective experience and recognition memory, potentially informing models like the Hemispheric Encoding/Retrieval Asymmetry (HERA) model.
