Holistic face processing can be independent of gaze behaviour: Evidence from the composite face illusion

People tend to perceive identical top halves (i.e. above the nose) of two face stimuli as being different when they are aligned with distinct bottom halves. This composite face illusion is generally considered as the most compelling evidence that facial features are integrated into a holistic representation. Here, we recorded eye‐movements during the composite face illusion in a delayed matching task of top halves of faces. Behavioural results showed a strong composite face effect, participants making more mistakes and taking longer time to match two identical top halves of faces when they were aligned (vs. misaligned) with different bottom halves. Importantly, fixation sites and eye‐movements were virtually identical when the top and bottom parts were aligned (composite illusion) or misaligned (no illusion), indicating that holistic face processing can be independent of gaze behaviour. These findings reinforce the view that holistic representations of individual faces can be extracted early on from information at a relatively coarse scale, independently of overt attention.     

A political economy approach to understanding the economic incorporation of Chinese sub-ethnic groups

This paper outlines the economic experiences of Toronto’s Chinese, 80% of whom are immigrants mostly arriving in the last two decades. Based on the 1996 census data, labour market participation and economic performance of various. Chinese sub-groups were compared. The findings contribute to an understanding of how selective immigration policies and world geopolitical changes can account for differences in economic adaptation and integration of sub-ethnic groups.     

Consommation de vin,pensée sociale et construction sociale de la normalité

This research was carried out in order to better understand the sense of “moderate” drinking and to test empirically hypothesis on the effect of the contextualisation on the social construction of normality as regards consumption. Results show that the answers of the participants on their “normal” and “pathological” representations of consumption are dependent on the context of the aforesaid consumption. When the participants consider that a quantity of wine in solitary context of consumption indicates an alcoholic tendency, they consider it normal in group context, whereas this quantity is significantly higher. The results are discussed compared to stigmatization of solitary consumption and the capacity of the social thinking concerning attribution of sense to the events and objects which surround us.     

Socially dependent auditory laterality in domestic horses (Equus caballus)

Laterality is now known to be an ubiquitous phenomenon among the vertebrates. Particularly, laterality of auditory processing has been demonstrated in a variety of species, especially songbirds and primates. Such a hemispheric specialization has been shown to depend on factors such as sound structure, species specificity and types of stimuli. Much less is known on the possible influence of social familiarity although a few studies suggest such an influence. Here we tested the influence of the degree of familiarity on the laterality of the auditory response in the domestic horse. This species is known for its social system and shows visible reactions to sounds, with one or two ears moving towards a sound source. By comparing such responses to the playback of different conspecific whinnies (group member, neighbor and stranger), we could demonstrate a clear left hemisphere (LH) preference for familiar neighbor calls while no preference was found for group member and stranger calls. Yet, we found an opposite pattern of ear side preference for neighbor versus stranger calls. These results are, to our knowledge, the first to demonstrate auditory laterality in an ungulate species. They open further lines of thought on the influence of the social “value” of calls and the listener’s arousal on auditory processing and laterality.     

Stereotype endorsement and perceived ability as mediators of the girls' gender orientation–soccer performance relationship

ObjectiveThis study investigated girls' endorsement of the stereotype that girls are not good soccer performers through three questions: (1) did stereotype endorsement predict soccer performance? (2) Was this relationship mediated by perceived ability? (3) Was stereotype endorsement related to gender role orientation?MethodOne hundred and two junior high school girls from the 6th to the 9th grade (M age = 13.5 years, SD = 1.23) reported their beliefs about girls' and boys' performance in soccer, perceived ability and gender role orientation. Next, their soccer performance was observed during matches in compulsory physical education classes. A path-analytic model tested the relationships among the variables using a product-moment correlation matrix and a maximum likelihood estimation procedure.ResultsStereotype endorsement (i.e., the belief that girls' performance in soccer is poor) negatively predicted performance, this relationship being mediated by perceived ability. Moreover, masculinity positively predicted perceived ability, and this relationship was partially mediated by stereotype endorsement.ConclusionThis study reinforces the idea that girls' sports performance may be related to gender stereotypes. Interpretations of the results in light of Eccles et al.’s expectancy-value model and stereotype threat theory are discussed, along with implications for practice.     

Predictors of Condom Use Among African American Males at High Risk for HIV1

This study compared the influence of HIV risk behaviors and condom use attitudes on condom use among heterosexual African American males. Three models were tested: (a) HIV risk, (b) condom use attitudes, and (c) a model combining the previous two. Brief street intercept interviews were administered to African American males in 2 matched pairs of census tracts. Results are based on 589 males reporting vaginal sex in the last 30 days. The General Linear Test (GLT) was used to test the ability of regression models to reduce error variance. The condom use, attitude model was sufficient to predict frequency of condom use regardless of partner type. The strongest predictors of condom use were condom use enjoyment, social norms, self-efficacy, and social influence.     

How much does a shared name make things similar? Part 1. Linguistic labels and the development of similarity judgment

Most theoretical proposals considering effects of language on similarity assume that labels affect similarity in a qualitative all-or-nothing manner. This article proposes another theoretical alternative--a model of the label as a discrete attribute of an object. According to this model, the relative weight of labels decreases with the child's age. Predictions derived from the model were tested in 3 experiments. In these experiments, children aged 6-12 years were presented with triads of schematic faces and were asked to make similarity judgments. Similarity of faces within the triads was manipulated via systematic variation of distinct facial features. It was found that (a) labels contribute to similarity judgment in a quantifiable manner, (b) labels' weight decreased with age, and (c) effects of labels are likely to stem from the cross-modality of labels. These results are discussed in relation to theories of development of categorization.
