The construct of the self is important in the domain of memory research. Recent work has shown that person memory is influenced by similarity of social targets to the self. The current experiments investigate self-similarity as defined by traits and political ideology to better understand how memory for social targets is organised. Across three experiments, participants formed positive or negative impressions based on each target’s picture, a trait-implying behavior (Experiments 1 & 2), and/or political ideology (conservative/liberal label in Experiment 2; (...) political-ideological belief statements in Experiment 3) followed by a memory test. Results showed a self-similarity effect dependent on valence in Experiment 1, but not in Experiments 2 or 3 when participants processed ideological information associated with targets. These results suggest that self-similarity has an effect on memory for social targets, but that ideological information disrupts self-focused processing of others, suggesting that ideological information also has a powerful influence on what people remember about others (i.e. social targets).

Deficits in the ability to read the emotions of others have been demonstrated in mental disorders, such as dissociation and schizophrenia, which involve a distorted sense of self. This study examined whether weakened self-referential source memory, being unable to remember whether a piece of information has been processed with reference to oneself, is linked to ineffective emotion recognition. In two samples from a college and community, we quantified the participants’ ability to remember the self-generated versus non-self-generated origins of sentences they (...) had previously read or partially generated. We also measured their ability to read others’ emotions accurately when viewing photos of people in affect-charged situations. Multinomial processing tree modelling was applied to obtain a measure of self-referential source memory that was not biased by non-mnemonic factors. Our first experiment with college participants revealed a positive correlation between correctly remembering the origins of sentences and accurately recognising the emotions of others. This correlation was successfully replicated in the second experiment with community participants. The current study offers evidence of a link between self-referential source memory and emotion recognition. (shrink)

Recent work has shown that memory for various types of information associated with social targets (impressions based on behaviours and political ideology) influences decisions to approach or avoid those same targets. The current study was intended to better understand the extent that memory for other types of details associated with targets (beliefs and behaviours) affects subsequent approach/avoidance decisions. In this investigation, participants formed impressions of social targets represented by a picture and a sentence (a belief in Experiment 1; either a (...) belief or behaviour in Experiment 2). Later, memory for the impressions and sentences associated with each target was tested. Finally, participants decided whether they would want to approach or avoid each target. Results demonstrated that accurate memory strongly influenced approach/avoidance decisions for targets associated with different types of information (beliefs; behaviours), although there was no difference in the effect of memory between beliefs and behaviours. Overall, results suggest an important role of memory in decisions to approach or avoid others. (shrink)
