Dynamic states in working memory modulate guidance of visual attention: Evidence from an n-back paradigm

Items held in working memory (WM) can automatically bias attention when they reappear in visual displays. Recent evidence, however, suggests that WM biases of attention may be reduced under certain conditions, for example with increasing memory load. We employed a dual task paradigm to investigate how WM biases are affected by dynamic updating of memory contents. 1-back and 2-back versions of a memory task with colour stimuli were interrupted at intervals by an unrelated visual search task. Reappearance in the search display of the item that was currently active in WM guided attention, while suppressed or inactive items did not. We conclude that the rapid updating of memory contents facilitates the shifting of memory representations into different activity states on a moment-to-moment basis. The finding is consistent with models that propose that only one item can be “active” in WM at any one time to guide attention.     

Can intergroup contact improve humanity attributions?

In this paper, intergroup contact was evaluated as a strategy to favor outgroup humanization. We tested a double‐mediation model, in which contact is associated with both decreased salience of intergroup boundaries and the adoption of a common identity. These recategorizations, in turn, are related to lower levels of anxiety and higher levels of empathy, both emotions being proximal predictors of outgroup humanization. The model was tested using structural equation modeling in the context of different intergroup relations: Italians versus immigrants (Study 1); Northern Italians versus Southern Italians (Study 2). Supporting the hypotheses, group representations and emotions mediated the relationship between contact and humanity attributions. The practical implications of results are discussed.

Conditions for dialogue and illuminating inequality in multicultural societies

In a recent article, Nesbitt‐Larking (2007) postulated the notion of ‘deep multiculturalism’, dependent, at least in part, on dialogue and on ‘host’ societies questioning their core values. In this commentary I suggest that whilst such a proposal is indeed a worthy ideal, the social psychological processes underpinning how this can be achieved need to be adequately addressed if such a vision is to become a reality. Using Social Representation Theory, I hope to explicate the operation of power, ideologies and collective memory on the process of representation, and suggest that understanding this process may better enable one to manage the obstacles involved in a project of deep multiculturalism. Drawing on Whiteness studies, I suggest that for a host society to question their core values, certain unconsciously held values need first to be illuminated; however, in so doing, I postulate that caution is exercised in order that such exposure does not perpetuate racialising representations. Using the concepts of anchoring and objectification, I propose that highlighting the similarities and shared experiences of a society's members may be a more successful strategy for achieving deep multiculturalism, than focusing on diversity and difference.

Sexual Subjectivity: A Semiotic Analysis of Girlhood, Sex, and Sexuality in the Film Juno

Historical approaches to girlhood provide a basis for understanding changing cultural ideologies of sex, sexuality, and youth. While situating sexual desire, biological possibilities, and social responses to girls’ engagement in sexual intercourse at the center of its plot, the film Juno depicts the transgressive sexual agency of a young girl without substantially disrupting longstanding discourses of femininity. Through an analysis of the semiotics of girlhood within the film, I argue that the girl figure in this representation signifies an amalgam of two traditionally dichotomized conceptions of “femininity.” Juno serves as a particularly intriguing example of the ways in which adolescent female sexuality is conceptualized within popular western culture during the early part of the 21st century.

The role of representational status and item complexity in parent–child conversations about pictures and objects

Mother–child conversations about pictures systematically differ from mother–child conversations about objects: Pictures are more likely than objects to elicit talk about kinds, whereas objects are more likely than pictures to elicit talk about individuals. The purpose of the current study is to examine whether this difference between pictures and objects is explained by differences in item complexity. Mothers and their 4-year-old children were randomly assigned to one of two conditions: simple or complex. In each condition, participants viewed 12 toy objects and 12 pictures, matched for content. The items were either highly detailed (complex condition) or very plain (simple condition). Replicating previous research, mothers and children provided relatively more focus on kinds when talking about pictures, and relatively more focus on individuals when talking about objects. The current results go further, however, to demonstrate that this effect is independent of the items’ complexity. We therefore propose that the picture–object difference is not due to low-level differences in amount of perceptual detail provided, but rather is due to the greater ease with which pictures serve as representations [DeLoache, J. S. (1991). Symbolic functioning in very young children: Understanding of pictures and models. Child Development, 62, 736–752]. These data indicate the ways in which a fundamental conceptual distinction between kinds and individuals arises in different linguistic expressions and in different contexts.     

Sex differences in social representations of aggression: Men justify,women excuse?

Women tend to hold an expressive social representation of aggression (as a loss of self‐control) while men tend to hold an instrumental representation (as a means of imposing control over others). Because expressive beliefs correspond to excuses and instrumental beliefs to justifications, it may be a sex difference in moral acceptability of aggression that informs social representation. Participants completed the Expagg questionnaire with reference to an episode of same‐sex or cross‐sex physical aggression and rated the moral acceptability of their behaviour. Women scored higher on Expagg (specifically lower than men on the instrumental scale) but there was no effect of target sex or participant‐by‐target interaction. Contrary to expectation, women rated their own aggression as more acceptable than did men and hence this could not explain their lower levels of instrumentality relative to men. Aggr.

Rhetorical representations of masculinities in South Africa: moving towards a material‐discursive understanding of men

A material‐discursive perspective holds advantage in understanding male realities. It seeks to integrate dominant approaches that appear anaemic in their failure to capture the interplay between the material and discursive realms of human existence. Three dominant metaphorical themes in the rhetorical representation of South African masculinities are described in an attempt to illustrate the complexity of embodied masculine experience. In this sense the discussion seeks to reveal the dynamic nature of masculine debate and lived experience across differing contexts. It serves to underline the importance of adopting a material‐discursive perspective in understanding men, which recognizes that they do not exist as a homogeneous social group, and as such experience their masculinities in a variable and changing fashion. The theoretical amalgamation of social representations and rhetoric is argued to provide a useful analytical tool in an endeavour of this nature. It is suggested that the rhetorical approach problematizes an overly consensual view of social reality that social representations theory typically promotes.

Verdi's Rigoletto: The dialectic interplay of the psychic positions in seemingly 'mindless' violence

In this paper the author demonstrates the interplay of the psychic positions (paranoid-schizoid and depressive, alongside more primitive mental states) as they may appear in experiences of overwhelming anxieties relating to fragmentation and disintegration. These are examined in relation to the appearance of what has been described in the literature as 'mindless' violence. The vehicle for this demonstration is Verdi's opera Rigoletto , which the author examines using Fonagy and Target's model for the understanding of mindless violence. The opera is 'read' as a case study of the protagonist, using the drama as a reflection of Rigoletto's internal object representations. The author attempts to extend Fonagy and Target's model to include primitive mental states, in order to understand 'mindless' violence as a result of collapse of the dialectical relationship of the psychic positions, leading to the violent act as a desperate attempt at re-establishing a sense of self. From this perspective, the moment of the violent act may be seen as use of an autistic object and as supplying of autistic shape. The violence is ultimately directed against the already fragmenting self, especially cherished parts of it, however it may enable acknowledgement of repudiated, unmentalised emotions previously experienced as a void.     

Tactile localization performance in children with developmental coordination disorder (DCD) corresponds to their motor skill and not their cognitive ability

When localizing touches to the hands, typically developing children and adults show a “crossed hands effect” whereby identifying which hand received a tactile stimulus is less accurate when the hands are crossed than uncrossed. This demonstrates the use of an external frame of reference for locating touches to one’s own body. Given that studies indicate that developmental vision plays a role in the emergence of external representations of touch, and reliance on vision for representing the body during action is atypical in developmental coordination disorder (DCD), we investigated external spatial representations of touch in children with DCD using the “crossed hands effect”. Nineteen children with DCD aged 7–11 years completed a tactile localization task in which posture (uncrossed, crossed) and view (hands seen, unseen) were varied systematically. Their performance was compared to that of 35 typically developing controls (19 of a similar age and cognitive ability, and 16 of a younger age but similar fine motor ability). Like controls, the DCD group exhibited a crossed hands effect, whilst their overall tactile localization performance was weaker than their peers of similar age and cognitive ability, but in line with younger controls of similar motor ability. For children with movement difficulties, these findings indicate tactile localization impairments in relation to age expectations, but apparently typical use of an external reference frame for localizing touch.
