Children's number processing is context dependent

The aim of this paper was to test the hypothesis of a context dependence of number processing in children. Fifth-graders were given two numbers presented successively on screen through a self-presentation procedure after being asked either to add or subtract or compare them. We considered the self-presentation time of the first number as reflecting the complexity of the encoding for a given planned processing. In line with Dehaene's triple-code model, self-presentation times were longer for additions and subtractions than for comparisons with two-digit numbers. Alternative interpretations of these results in terms of more cognitive effort or more mental preparation in the case of addition and subtraction than comparison are discussed and ruled out.     

Book reviews

Over the last 30 years or so, various findings have been reported which suggest that the perception of spoken words may involve the automatic coactivation of orthographic properties. Here we assessed this possibility in auditory rhyme judgement tasks and replicated a classic finding reported by Seidenberg and Tanenhaus (1979), showing that orthographic similarity between stimuli facilitated responses on rhyming pairs, but had the opposite effect on nonrhyming pairs. However, Experiments 2 and 3 showed that manipulating the nature of the nonrhymes, or adding a large proportion of filler items, eliminated the effects of orthographic match or mismatch. These findings suggest the involvement of strategic factors in the emergence of orthographic effects in rhyme judgement tasks.     

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 developmental turnpoint of orthographic consistency effects in speech recognition

The influence of orthography on children's online auditory word recognition was studied from the end of Grade 4 to the end of Grade 9 by examining the orthographic consistency effect in auditory lexical decision. Fourth-graders showed evidence of a widespread influence of orthography in their spoken word recognition system; words with rimes that can be spelled in two different ways (inconsistent) produced longer auditory lexical decision times and more errors than did consistent words. A similar consistency effect was also observed on pseudowords. With adult listeners, on exactly the same material, we replicated the usual pattern of an orthographic consistency effect restricted to words in lexical decision. From Grade 6 onward, this adult pattern of orthographic effect on spoken recognition is already observable.     

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.
