Language is not necessary for color categories

The origin of color categories is under debate. Some researchers argue that color categories are linguistically constructed, while others claim they have a pre‐linguistic, and possibly even innate, basis. Although there is some evidence that 4–6‐month‐old infants respond categorically to color, these empirical results have been challenged in recent years. First, it has been claimed that previous demonstrations of color categories in infants may reflect color preferences instead. Second, and more seriously, other labs have reported failing to replicate the basic findings at all. In the current study we used eye‐tracking to test 8‐month‐old infants’ categorical perception of a previously attested color boundary (green–blue) and an additional color boundary (blue–purple). Our results show that infants are faster and more accurate at fixating targets when they come from a different color category than when from the same category (even though the chromatic separation sizes were equated). This is the case for both blue–green and blue–purple. Our findings provide independent evidence for the existence of color categories in pre‐linguistic infants, and suggest that categorical perception of color can occur without color language.     

The influence of writing practice on letter recognition in preschool children: a comparison between handwriting and typing

A large body of data supports the view that movement plays a crucial role in letter representation and suggests that handwriting contributes to the visual recognition of letters. If so, changing the motor conditions while children are learning to write by using a method based on typing instead of handwriting should affect their subsequent letter recognition performances. In order to test this hypothesis, we trained two groups of 38 children (aged 3-5 years) to copy letters of the alphabet either by hand or by typing them. After three weeks of learning, we ran two recognition tests, one week apart, to compare the letter recognition performances of the two groups. The results showed that in the older children, the handwriting training gave rise to a better letter recognition than the typing training.     

Why Do Women Endorse Honor Beliefs? Ambivalent Sexism and Religiosity as Predictors

Cultures of honor, such as Turkey, prioritize defending individual and family reputations, but in gender-specific ways (Nisbett and Cohen 1996). Men maintain honor via reputations for toughness, aggression, control over women, and avenging insults. Women maintain honor through obedience to men, sexual modesty, and religious piety. Honor beliefs support women’s subordination, justifying violence against them (Sev’er and Yurdakul, Violence against Women, 7, 964–998, 2001) and therefore should be challenged. Understanding honor beliefs’ ideological correlates may inform such efforts. We hypothesized that benevolent sexism, a subjectively favorable system-justifying ideology, would more strongly, positively predict Turkish women’s (versus men’s) honor beliefs; whereas hostile sexism, which is openly antagonistic toward women, would more strongly, positively predict Turkish men’s (versus women’s) honor beliefs. Additionally, due to justifications for gender inequality embedded in Islamic religious teachings, we expected Islamic religiosity to positively predict honor beliefs for both genders. A convenience sample of Turkish undergraduates (313 women and 122 men) in Ankara completed the Ambivalent Sexism Inventory, Religious Orientation Scale, and Honor Endorsement Index. Regression analyses revealed that benevolent (but not hostile) sexism positively predicted women’s honor beliefs, whereas hostile (but not benevolent) sexism positively predicted men’s honor beliefs. Islamic religiosity positively predicted honor beliefs for both genders, but (unexpectedly) did so more strongly for men than women. We suggest that combating benevolent sexism and promoting feminist interpretations of Islamic religiosity may help to empower Turkish women to challenge honor beliefs.     

Relation between perceived scholastic competence and social comparison mechanisms among elementary school children

According to the literature, among social comparison mechanisms, identification with an upward target would be the most frequent mechanism that students report to use. However, it remains unclear how the identification and the contrast mechanisms contribute to the construction of pupils’ scholastic perceived competence. The aim of this study was to test the two following hypotheses: (1) the more pupils report using downward identification and upward contrast, the lower their perceived scholastic competence; (2) the more pupils report using upward identification and downward contrast, the higher their perceived scholastic competence will be. Three hundred and eighty French-speaking pupils (147 fourth graders and 233 fifth graders) from public elementary schools in the district of Grenoble (France) were met in their school. Pupils responded to a standardized mental ability test and to a questionnaire about their perceived scholastic competence and their utilization of social comparison mechanisms: upward and downward identification and upward and downward contrast. Boys and girls differed on some of the social comparison mechanisms. However, the two hypotheses were confirmed and hold true for both boys and girls. Findings show that beyond the contribution of cognitive abilities, pupils’ responsiveness to these mechanisms contributed to the development of their perceived scholastic competence. One educational implication is the usefulness of analyzing the processes of social comparison as strategies to allow pupils to maintain a positive perception of their scholastic competence.     

The relationships between Internet addiction, subjective vitality, and subjective happiness

The aim of the present study is to examine the relationships between Internet addiction, subjective vitality, and subjective happiness. The participants were 328 university students who completed a questionnaire package that included the Online Cognition Scale, the Subjective Vitality Scale, and the Subjective Happiness Scale. According to the results, subjective vitality and subjective happiness were negatively predicted by Internet addiction. On the other hand, subjective happiness was positively predicted by subjective vitality. In addition, subjective vitality mediated the relationship between Internet addiction and subjective happiness. Results were discussed in light of the literature.

Exploring the impact of plasticity-related recovery after brain damage in a connectionist model of single-word reading

The effect of retraining a damaged connectionist model of single-word reading was investigated with the aim of establishing whether plasticity-related changes occurring during the recovery process can contribute to our understanding of the pattern of dissociations found in brain-damaged patients. In particular, we sought to reproduce the strong frequency × consistency interactions found in surface dyslexia. A replication of Plaut, McClelland, Seidenberg, and Patterson’s (1996) model of word reading was damaged and then retrained, using a standard backpropagation algorithm. Immediately after damage, there was only a small frequency × consistency interaction. Retraining the damaged model crystallized out these small differences into a strong dissociation, very similar to the pattern found in surface dyslexic patients. What is more, the percentage of regularization errors, always high in surface dyslexics, increased greatly over the retraining period, moving from under 10% to over 80% in some simulations. These results suggest that the performance patterns of brain-damaged patients can owe as much to the substantial changes in the pattern of connectivity occurring during recovery as to the original premorbid structure. This finding is discussed in relation to the traditional cognitive neuropsychological assumptions of subtractivity and transparency.
