Hijab,visibility and the performance of identity

Theories concerning the relationship between social identification and behaviour are increasingly attentive to how group members emphasise or de‐emphasise identity‐related attributes before particular audiences. Most research on this issue is experimental and explores the expression of identity‐related attitudes as a function of participants' beliefs concerning their visibility to different audiences. We extend and complement such research with an analysis of group members' accounts of their identity performances. Specifically, we consider British Muslim women's (n = 22) accounts of wearing hijab (a scarf covering the hair) and how this visible declaration of religious identity is implicated in the performance of their religious, national and gender identities. Our analysis extends social psychological thinking on identity performance in three ways. First, it extends our understandings of the motivations for making an identity visible to others. Second, it sheds light on the complex relationship between the performance of one (e.g. Muslim) identity and the performance of other (e.g. gender/national) identities. Third, it suggests the experience of making an identity visible can facilitate the subsequent performance of that identity. The implications of these points for social identity research on identity performance are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Vocal learning of a communicative signal in captive chimpanzees, Pan troglodytes

We hypothesized that chimpanzees could learn to produce attention-getting (AG) sounds via positive reinforcement. We conducted a vocal assessment in 76 captive chimpanzees for their use of AG sounds to acquire the attention of an otherwise inattentive human. Fourteen individuals that did not produce AG sounds during the vocal assessment were evaluated for their ability to acquire the use of an AG sound through operant conditioning and to employ these sounds in an attention-getting context. Nine of the 14 chimpanzees were successfully shaped using positive reinforcement to produce an AG sound. In a post-training vocal assessment, eight of the nine individuals that were successfully trained to produce AG sounds generalized the use of these newly acquired signals to communicatively relevant situations. Chimpanzees possess the ability to acquire the use of a communicative signal via operant conditioning and can generalize the use of this newly acquired signal to appropriate communicative contexts.     

Identity,Culture and Contestation: Social Identity as Cross-Cultural Theory

In this paper we explore the logic and implications of the social identity approach to group processes. The theory argues that the consequences of social identification for behaviour are not simple givens. Rather than making generalisations about the behaviour that flows from social identification, the theory makes the point that behaviour depends upon the way in which identities are defined. This emphasis upon the contents of social identities draws our attention to their construction and we pay particular attention to how group identities are made and remade in and through argument and social practice. We argue that attention to the dynamics of identity construction means that this perspective is respectful of culture and cultural difference and that the social identity approach therefore has considerable value in exploring the politics and practice of identity wherever group behaviour may be found. Moreover, we argue that the ubiquity of identity-related argument across cultures and contexts reflects the fact that group identity is a basis for social power.     

The impact of adopting ethnic or civic conceptions of national belonging for others' treatment

National belonging is often defined in terms of "ethnic" ancestry and "civic" commitment (with the latter typically implying a more inclusive conception of belonging). The authors report three Scottish studies manipulating the prominence of these criteria. In Study 1 (N = 80), a Chinese-heritage target was judged more Scottish (and his criticisms of Scotland better received) when Scotland was defined in civic terms. In Study 2 (N = 40), a similar manipulation in a naturalistic setting showed a civic conception of belonging resulted in more help being given to a Chinese-heritage confederate. Study 3 (N = 71) replicated Study 2 and showed the effect was mediated by judgments of the confederate's Scottishness. These studies emphasize the importance of exploring how ingroup identity is defined.     

Recognition memory and the hippocampus: A test of the hippocampal contribution to recollection and familiarity

It has been suggested that the hippocampus selectively supports recollection and that adjacent cortex in the medial temporal lobe can support familiarity. Alternatively, it has been suggested that the hippocampus supports both recollection and familiarity. We tested these suggestions by assessing the performance of patients with hippocampal lesions on recognition memory tests that differ in the extent to which recollection and familiarity contribute to the recognition decision. When targets and foils are highly similar, prior evidence suggests that, on a forced-choice test in which targets are presented together with highly similar, corresponding foils (the FC-C format), performance is supported primarily by familiarity. By contrast, when targets are presented together with foils that are similar to other targets (the FC-NC format) or when memory is tested in a yes/no (Y/N) format, performance is based much more strongly on recollection. Accordingly, a finding that hippocampal damage impaired both Y/N recognition and FC-NC recognition but spared FC-C recognition would suggest that the hippocampus selectively supports recollection. We administered Y/N, FC-C, and FC-NC tests to five memory-impaired patients with circumscribed hippocampal lesions and 14 controls. The patients were impaired on all three types of recognition test, and there was no indication that the patients were disproportionately benefited or disproportionately impaired on any test. This pattern of performance suggests that the hippocampus supports both recollection and familiarity.The medial temporal lobe (the hippocampus plus the entorhinal, perirhinal, and parahippocampal cortices) is essential for the recognition of past experience. The capacity for recognition is widely thought to depend on two distinct processes, recollection and familiarity (Mandler 1980; Yonelinas et al. 2002; Wixted 2007). Recollection involves remembering specific details about the episode in which an item was encountered. Familiarity involves simply knowing that an item was presented, even when no additional information can be retrieved about the learning episode itself. This distinction has been prominent in recent discussions about memory, particularly in relation to its possible anatomical basis. One proposal is that recollection depends on the hippocampus and that familiarity depends on the adjacent medial temporal lobe cortex (Brown and Aggleton 2001; Mayes et al. 2002; Yonelinas et al. 2002). Alternatively, it has been suggested that the hippocampus is important for both recollection and familiarity and that the distinction between these two processes does not illuminate the functional differences between the hippocampus and adjacent cortex (Rutishauser et al. 2006; Wais et al. 2006; Squire et al. 2007; Wixted 2007).To clarify the role of the hippocampus in recognition memory, the performance of memory-impaired patients with hippocampal damage has often been compared to that of controls on tests that differ in the extent to which recollection and familiarity contribute to the recognition memory decision. One such approach involves the use of highly similar targets and foils tested using a yes/no (Y/N) format and a forced-choice corresponding (FC-C) format (Holdstock et al. 2002; Westerberg et al. 2006; Bayley et al. 2008). In the case of the Y/N format, participants see a list of targets intermixed with foils (each similar to one of the targets) and are asked to respond “yes” to the targets and “no” to the foils. In the FC-C format, participants see a target presented together with its corresponding, similar foil and are asked to identify the target. According to an idea advanced by Norman and O''Reilly (2003), familiarity can support FC-C recognition because one can make effective use of small but consistent differences between the familiarity signals triggered by the target and foil items. That is, when targets and foils are highly similar and are presented together in the FC-C format, familiarity for the target is likely to slightly and reliably exceed that of the similar foil, allowing the target to be correctly chosen on the basis of familiarity. By contrast, in the Y/N format, slight differences between the familiarity signals of target items and their corresponding foils no longer provide useful information, because the targets and their corresponding foils are not presented together at test. Accordingly, good performance with the Y/N format is more dependent on recollection than with the FC-C format.The same explanation may account for why performance on FC-C tests sometimes exceeds performance on forced-choice noncorresponding (FC-NC) tests (e.g., Hintzman 1988). In the FC-NC format, target items are presented together with a noncorresponding foil that is similar to another target item from the study list (Fig. 1). Thus, the FC-C and FC-NC tests differ only in that the similar targets and foils are presented together in the former but not in the latter. When the corresponding targets and foils are presented together (in the FC-C format), participants can make effective use of consistent differences in familiarity values (as discussed above). When the corresponding targets and foils are not presented together, participants cannot make use of the small differences that they might detect through a side-by-side comparison.Open in a separate windowFigure 1.Test format and materials for the three kinds of recognition test. For each test, 12 images, either objects (A) or silhouettes (B), were presented at study, and memory was tested in one of three ways. For the forced-choice corresponding test (FC-C), each target (a studied item) was presented together with a highly similar foil (a new item). For the forced-choice noncorresponding test (FC-NC), each target was presented together with a foil that was highly similar to a different target from the study list. Participants were asked to point to exactly the same image they had seen during study. For the yes/no test (Y/N), the 12 targets and the 12 foils (each similar to one of the targets) were intermixed and presented one at a time. Participants were asked to respond “yes” if they had seen exactly the same image before and “no” if they had not. Asterisks identify the target items.A recent study (Migo et al. 2009) provides empirical support for the suggestion that familiarity primarily contributes to the recognition decision in the FC-C format, whereas recollection contributes more strongly in the Y/N format and in the FC-NC format. In the Migo et al. (2009) study, healthy participants received FC-C, FC-NC, and Y/N tests after receiving either standard instructions to make their decisions based on familiarity or recollection or modified instructions to base their decisions on familiarity only. On the FC-NC test and on the Y/N test, performance using familiarity alone was significantly worse than under standard instructions. On the FC-C test, performance using familiarity alone was nearly as good as under standard instructions. This result supports the earlier suggestion that FC-C is primarily supported by familiarity, whereas recollection plays a larger role in FC-NC and Y/N recognition (Norman and O''Reilly 2003).If the hippocampus is critical for recollection but not for familiarity, and if good performance on the FC-C format can be achieved using familiarity alone, then patients with focal hippocampal lesions should be differentially impaired on the Y/N and FC-NC recognition test formats compared with the FC-C format. Three recent studies investigated this issue by assessing the effects of hippocampal damage (or presumed hippocampal damage) on Y/N and FC-C tests that used highly similar targets and foils (the FC-NC format was not used in these earlier studies). All three studies used black-and-white silhouette images of objects, and the FC-C test involved the target item and three similar foils (i.e., multiple-choice with four alternatives). In one study, a single patient with bilateral hippocampal damage (patient Y.R.) was impaired on the test of Y/N recognition but was unimpaired on the test of FC-C recognition (Holdstock et al. 2002). A similar result was reported in patients with a diagnosis of mild cognitive impairment (MCI) (Westerberg et al. 2006). These findings have been taken to support the suggestion that the hippocampus selectively supports recollection. However, the study by Holdstock and colleagues (2002) involved a single patient (Y.R.), and findings from a single patient need not agree with findings obtained from a group of patients (see Discussion). In addition, the Westerberg et al. (2006) study involved individuals with a diagnosis of MCI for whom anatomical data were not available. It is therefore not clear what the status of the hippocampus was in these patients. Moreover, a standard Y/N procedure involving 12 study items and 24 test items (as opposed to the 12 study test items and 60 test items used in previous studies [Holdstock et al. 2002; Westerberg et al. 2006; Bayley et al. 2008]) might be better suited to address the question of whether Y/N recognition is selectively impaired in hippocampal patients. Bayley et al. (2008) tested five patients with circumscribed hippocampal damage using the same test materials and procedure as in Holdstock et al. (2002). When all 60 test items of the Y/N test were scored, the patients were found to be more impaired on the Y/N test than on the FC-C test. However, when only the first 24 test items of the Y/N test were scored (according to the standard Y/N procedure), the patients were found to be impaired on both the Y/N and FC-C tests to a similar degree.The earlier studies (Holdstock et al. 2002; Westerberg et al. 2006; Bayley et al. 2008) compared Y/N recognition to four-alternative FC-C recognition in which each target was presented along with three corresponding foils. None of the earlier studies investigated how patients with hippocampal lesions performed on FC-NC recognition. As Migo et al. (2009) point out, FC-C and FC-NC tests are better matched than the FC-C and Y/N tests because they are both forced-choice tests, and both use the same number of test trials. As such, they argue, it would be more useful to compare FC-C recognition performance to FC-NC recognition performance to determine whether patients with hippocampal lesions are intact or impaired on familiarity-based tests.The present study assessed Y/N, two-alternative FC-C, and two-alternative FC-NC recognition, using highly similar targets and foils. The tests were given to five patients with circumscribed hippocampal damage and 14 matched controls. The Y/N test involved an equal number of targets and foils (unlike the design used in the prior studies), and a two-alternative format was used for the forced-choice tests to make them comparable to the Y/N test (i.e., all three tests involved the same number of targets and foils). The FC-C and FC-NC tests were identical except with respect to how the targets and their corresponding foils were paired on the recognition test.To extend our findings beyond the stimuli used in prior studies, we also used color photographs of objects in addition to black-and-white silhouettes. Using these three test formats, we asked the following questions: (1) Does hippocampal damage impair Y/N recognition memory but spare, or disproportionately benefit, FC-C recognition (as suggested by the view that the hippocampus supports recollection and not familiarity)? Or does hippocampal damage impair Y/N and FC-C recognition similarly (as suggested by the view that the hippocampus supports both recollection and familiarity)? (2) Does hippocampal damage disproportionately benefit FC-C recognition relative to FC-NC recognition, or does hippocampal damage impair FC-C and FC-NC recognition similarly?     

Responses of Three Muslim Majority Primary Schools in England to the Islamic Faith of Their Pupils

This paper considers the responses of three English primary schools to the education of their Muslim pupils. It begins by setting out the context of discussion about Muslims and education in Europe as well as by describing some of the structural and pedagogical characteristics and trends in English education influencing the schools’ options and choices. The main body of the article is a comparative analysis of the three schools, focusing on the approaches of teachers and school leaders to the faith backgrounds of their pupils, their constructions of Islam for these educational contexts, and their preparation of Muslim children for a religiously plural Britain. As the schools devise strategies and select between options, they provide in microcosm differing models of the inclusion of minority Islam in a western society.     

Social Identity and Spatial Behaviour: The Relationship between National Category Salience, the Sense of Home, and Labour Mobility across National Boundaries

This study explores the impact of manipulating the salience of national categories upon the willingness of highly identifying Scots to take up either short-term or long-term jobs in Scotland as compared to England. The results support the hypotheses (a) that high-identifying Scots increase preference for intra- over extranational locations when national categories are salient, (b) that this effect is fully mediated by "fitting in"—that is, the sense of being "at home" in Scottish as compared to English locations, and (c) that these relationships only hold for long-term as opposed to short-term jobs. We discuss these results in terms of the impact of identity definitions upon spatialised action and the economic/political importance of this relationship.     

From hand to mouth in the evolution of language: the influence of vocal behavior on lateralized hand use in manual gestures by chimpanzees (Pan troglodytes)

Studies in human subjects indicate that manual gestures accompanied by speech are produced more often by the right compared to the left hand. Additional studies indicate that the production of sign language is controlled by the same brain areas as speech, suggesting similar neurobiological substrates for language that are not modality specific. We report evidence that chimpanzees exhibit preferential use of the right hand in gestural communication. Moreover, use of the right hand in gestural communication is significantly enhanced when accompanied by a vocalization, particularly among human‐reared chimpanzees. Taken together, the data suggest that the lateralization of manual and speech systems of communication may date back as far as 5 million years ago.     

The role of social categorization and identity threat in the perception of migrants

This paper investigates how the categorization of migrant workers shapes their reception. In an experiment with Northern Irish Protestants we manipulated the representation of Poland to make the Catholicism of Polish migrants either more, or less, salient. Furthermore, judgements of Polish migrants were obtained under conditions designed to encourage participants to believe that sectarian conflict in Northern Ireland was either resolved, or still a strong feature of the present social landscape. Overall, results showed that when Poland's Catholicism was salient, participants were less welcoming of Polish migrants. Furthermore, this effect was mediated by increases in the level of symbolic threat participants believed the migrants posed to participants' (Protestant) community identity.
