Varieties of the extended self

This article provides an overview and analysis of recent work on the extended self, demonstrating that the boundaries of selves are fluid, shifting across biological, artifactual, and sociocultural structures. First, it distinguishes the notions of minimal self, person, and narrative self. Second, it surveys how philosophers, psychologists, and cognitive scientists argue that embodiment, cognition, emotion, consciousness, and moral character traits can be extended and what that implies for the boundaries of selves. It also reviews and responds to various criticisms and counterarguments against the extended self. The main focus is on the link between the extended mind and extended self, which has received the most attention in recent literature. But accounts of the extended self developed independently of the extended mind are also briefly discussed. This article ends by drawing out some of the conceptual, methodological, and normative implications of the extended self and suggesting some directions for future research.     

Secondary attachments and adolescent self concept

This study examined the popular notion that crushes or secondary attachments to celebrity figures are an important aspect of self-concept development during adolescence. In a repeated measures design, 79 male and female 5th, 8th, and 11th graders and college sophomores completed a set of personality scales, first describing themselves and later, describing the favorite celebrity. Repeated measures multivariate analyses of variance (MANOVA) analysis of self-object congruence revealed no significant main or interaction effects for the type of attachment, gender, or age of subject. Significant within subject effects were obtained for the repeated measures factor (self-object congruence). Overall, students perceived their attachment objects to be more agentic, yet less expressive and emotionally vulnerable than themselves. MANOVA analyses indicated that males and older students perceived their attachment objects to be higher in agency than expressivity, whereas females and younger students perceived their attachment objects to be higher in expressivity than agency. These data indicate that the function served by secondary attachments in the development of self-concept may be quite similar for adolescent males and females.     

Self-attention,concept activation,and the causal self

Two experiments examined the relationship between the accessibility of selfreferent information and attributions of causal responsibility to the self. The first study introduced a priming technique, in which subjects used either first-person or third-person terms in a story construction task, to directly access self-referent or other-referent thought. It was found that self-attributions for hypothetical outcomes were greater for those subjects whose earlier stories were focused on the self. The second study, rather than activate self-referent cognition in a general fashion, sought to explicitly prime the notion of a “causal self.” In addition to self-referent or other-referent words, subjects were also given words that evoked notions of either causality or noncausality to be incorporated into their stories. Contingent activation of both “self” and “causal” notions subsequently resulted in greater self-attributions than any other experimental condition. Recall and recognition data from Experiment 2 were generally consistent with the contention that a specific and differentiated component of the self-schema had been accessed. The results of both studies, as well as the novel “self-priming” technique, are discussed in terms of self-awareness theory.     

The trans-species concept of self and the subcortical-cortical midline system

The nature of the self has been one of the central problems in philosophy and most recently in neuroscience. Here, we suggest that animals and humans share a 'core self' represented in homologous underlying neural networks. We argue that the core self might be constituted by an integrative neuronal mechanism that enables self-related processing (SRP). Because mammalian organisms are capable of relating bodily states, intrinsic brain states (e.g. basic attentional, emotional and motivational systems) and environmental stimuli to various life-supporting goal-orientations, SRP appears to be a core ability preserved across numerous species. Recent data suggest that SRP is operating via a central integrative neural system made up of subcortical-cortical midline structures (SCMSs), that are homologous across mammalian species.     

The self concept of the adolescent with learning disabilities

The Coopersmith Self Esteem Inventory (CSEI) was administered to 23 Ss diagnosed to have learning disabilities, and normally achieving seventh graders (N = 70) to investigate: a) whether differences exist between the self-esteem of the adolescent with learning disabilities and the normally achieving adolescent, b) the dimensions of self concept in which these differences occur, and c) the relationship between self concept and the number of years in the special classroom for the adolescent with learning disabilities. The data were fitted to a 2 X 2 (ability X school) fixed effects non-orthogonal multivariate analysis of variance model. A significant difference (p less than .05) in "social self-peer" self concept favoring the "normally" achieving S's was found. A trend was evidenced for more negative "general self" and "school-academic" self concepts for the learning disabilities sample. Number of years in the special class did not appear associated with self concept as measured by the CSEI.
