A review of self-processing biases in cognition

When cues in the environment are associated with self (e.g., one’s own name, face, or coffee cup), these items trigger processing biases such as increased attentional focus, perceptual prioritization and memorial support. This paper reviews the existing literature on self-processing biases before introducing a series of studies that provide new insight into the influence of the self on cognition. In particular, the studies examine affective and memorial biases for self-relevant stimuli, and their flexible application in response to different task demands. We conclude that self-processing biases function to ensure that self-relevant information is attended to and preferentially processed because this is a perpetual goal of the self-system. However, contrary task-demands or priming can have an attenuating effect on their influence, speaking to the complexity and dynamism of the self-processing system in cognition

Culture modulates implicit ownership-induced self-bias in memory

The relation of incoming stimuli to the self implicitly determines the allocation of cognitive resources. Cultural variations in the self-concept shape cognition, but the extent is unclear because the majority of studies sample only Western participants. We report cultural differences (Asian versus Western) in ownership-induced self-bias in recognition memory for objects. In two experiments, participants allocated a series of images depicting household objects to self-owned or other-owned virtual baskets based on colour cues before completing a surprise recognition memory test for the objects. The ‘other’ was either a stranger or a close other. In both experiments, Western participants showed greater recognition memory accuracy for self-owned compared with other-owned objects, consistent with an independent self-construal. In Experiment 1, which required minimal attention to the owned objects, Asian participants showed no such ownership-related bias in recognition accuracy. In Experiment 2, which required attention to owned objects to move them along the screen, Asian participants again showed no overall memory advantage for self-owned items and actually exhibited higher recognition accuracy for mother-owned than self-owned objects, reversing the pattern observed for Westerners. This is consistent with an interdependent self-construal which is sensitive to the particular relationship between the self and other. Overall, our results suggest that the self acts as an organising principle for allocating cognitive resources, but that the way it is constructed depends upon cultural experience. Additionally, the manifestation of these cultural differences in self-representation depends on the allocation of attentional resources to self- and other-associated stimuli

The function of the self-attention network

This commentary links Humphrey and Sui’s proposed Self-attention Network (SAN) to the memory advantage associated with self-relevant information (i.e., the self-reference effect). Articulating this link elucidates the functional quality of the SAN in ensuring that information of potential importance to self is not lost. This adaptive system for self-processing mirrors the cognitive response to threat stimuli, which also elicit attentional biases and produce characteristically enhanced, episodic representations in memory. Understanding the link between the SAN and memory is key to comprehending more broadly the operation of the self in cognition

The self-reference effect on memory in early childhood

The self-reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self- or other-image paired with a concrete object. In Study 1, 4- to 6-year-old children (N = 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self-paired objects. Study 2 (N = 55) replicated this finding in source memory. In Study 3 (N = 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self-paired items. These findings are discussed with reference to mechanisms that ensure information of potential self-relevance is reliably encoded

Applying self-processing biases in education:improving learning through ownership

Accepting ownership of an item is an effective way of associating it with self, evoking self-processing biases that enhance memory. This memory advantage occurs even in ownership games, where items are arbitrarily divided between participants to temporarily ‘own’. The current study tested the educational applications of ownership games across two experiments. In Experiment 1, 7 to 9-year-old children were asked to choose three novel, labelled shapes from an array of nine. The experimenter chose three shapes and three remained ‘un-owned’. A subsequent free-recall test showed that children reliably learned more self-owned than other-owned or un-owned shapes. Experiment 2 replicated this finding for shapes that were assigned to owners rather than chosen, and showed that ownership enhanced memory more effectively than a control game with no ownership manipulation. Together, these experiments show that ownership games can evoke self-processing biases in children’s memory, enhancing learning. Implications for education strategies are discussed

Developmental perspectives on the behaviour of missing children:exploring changes from early childhood to adolescence

Despite the inherent vulnerability of missing children and the associated emotional intensity for those affected, there has been no academic exploration of child development and missing behaviour. The current enquiry comprised an examination of police case records to determine how the circumstances and behaviour of missing children varies across early childhood (2-6 years; n = 79; 10.3%), middle childhood (7-11 years; n = 175; 22.9%), and adolescence (12-17 years; n = 512; 66.9%). Children were more likely to go missing in adolescence than early or middle childhood, and more boys than girls were reported missing before adolescence, with the opposite pattern found during adolescence. Adolescents travelled further, took public transport more, and were more likely to be accompanied than those in the younger age groups. Children in the youngest age group were more likely to go missing unintentionally, whereas adolescents were more likely to run away intentionally. Based on these findings it is argued that developmentally informed understanding should contribute to future strategies for preventing and responding to missing children

The spontaneous formation of stereotypes via cumulative cultural evolution

All people share knowledge of cultural stereotypes of social groups—but what are the origins of these stereotypes? We examined whether stereotypes form spontaneously as information is repeatedly passed from person to person. As information about novel social targets was passed down a chain of individuals, what initially began as a set of random associations evolved into a system that was simplified and categorically structured. Over time, novel stereotypes emerged that not only were increasingly learnable but also allowed generalizations to be made about previously unseen social targets. By illuminating how cognitive and social factors influence how stereotypes form and change, these findings show how stereotypes might naturally evolve or be manipulated

Survival of the selfish: contrasting self-referential and survival-based encoding

Processing information in the context of personal survival scenarios elicits a memory advantage, relative to other rich encoding conditions such as self-referencing. However, previous research is unable to distinguish between the influence of survival and self-reference because personal survival is a self-referent encoding context. To resolve this issue, participants in the current study processed items in the context of their own survival and a familiar other person’s survival, as well as in a semantic context. Recognition memory for the items revealed that personal survival elicited a memory advantage relative to semantic encoding, whereas other-survival did not. These findings reinforce suggestions that the survival effect is closely tied with self-referential encoding, ensuring that fitness information of potential importance to self is successfully retained in memory
