The Impact of Parenting Experience on Gender Stereotyped Toy Play of Children

The purpose of this study was to examine gender role socialization as a function of parenting experience in an actual toy play situation and as a function of adults' perceptions of typically gender-stereotyped children's toys. Each of 48 children (24 boys and 24 girls) played with 3 adults: either his or her own mother or father, a matched mother or father of another child, and a matched man or woman who was not a parent. The amount of time children and adults played with gender-specific toys, adults' categorization of toys into gender categories, and adults' desirability ratings of gender-specific toys were examined. The gender-sorting task revealed that adults did not agree with traditional expert categorizations of some of the toys, which suggests a shift in the perceived function of some traditionally stereotyped toys. Regardless of how parents sorted toys into categories, when playing with boys, most time was spent with masculine toys. With girls, however, there was greater flexibility in the categories of toys with which they played. Parenting experience influenced the perceived desirability of toys; parents found toys more desirable than nonparents but these differences did not affect the actual play session with children. These results suggest a change in perceptions of traditionally stereotyped toys and differences as a function of gender in what is appropriate gender-typing behavior.     

Symbols presentation modality as a determinant of gambling behavior

In this study, the authors investigated the effects that modality of symbol presentation on video lottery terminals (sequential vs. simultaneous) has on gambling behavior. They predicted that sequential presentation would incite players to prolong their gambling session. Results confirmed this prediction and showed that modality of presentation is a determinant of gambling persistency. The authors discuss the relationship between modality of presentation, hopes of an imminent win, losses, and practical and theoretical issues about other cognitive and emotional elements that may influence gamblers' behaviors.     

French descriptions of Wundt's laboratory in Leipzig in 1886

Translations are provided of extracts from reports by the French-speaking scholars Alfred Grafé and Emile Durkheim concerning the instructional procedures in place at Wundt's Institute for Experimental Psychology in Leipzig in the summer of 1886. It is stressed that reports such as theirs were of importance, not only to researchers, but also to teachers and administrators concerned with how the new experimental psychology should be taught, especially with respect to practical classes.     

Neural substrates of impaired categorical perception of phonemes in adult dyslexics: an fMRI study

Phonological developmental dyslexics remain impaired in phonetic categorical perception (CP) even in adulthood. We studied the brain correlates of CP in dyslexics and controls using a block design fMRI protocol and stimuli from an phonetic continuum between natural /Pa/ and /Ta/ syllables. Subjects performed a pseudo-passive listening task which does not imply voluntary categorical judgment. In the control group, categorical deviant stimuli elicited specific activations in the left angular gyrus, the right inferior frontal gyrus and the right superior cingulate cortex. These regions were not activated in the dyslexic group in which activation was observed for acoustic but not phonetic changes in stimuli. Failures to activate key regions for language perception and auditory attention in dyslexic might account for persistent deficits in phonological awareness and reading tasks.     

Further exploration memory bias in compulsive washers

The aim of the present study was to replicate Radomsky and Rachman's findings on memory bias in obsessive-compulsive disorder (OCD), using the same procedure but an increased sample size, more specific control groups, and a full analysis of contamination attribution data. Sixteen OCD-washers, 16 OCD-checkers, 16 social phobic patients and 16 non-anxious controls were presented with 50 'clean' or 'dirty' objects. After this incidental encoding phase, participants were asked to freely recall the objects, to rate their anxiety when almost touching each object, and, finally, to attribute each object to one of the two contamination conditions ('clean' or 'dirty'). Verbal episodic memory was also assessed with the California Verbal Learning Test. The results indicate that, contrary to Radomsky and Rachman's findings, OCD-washers did not differ from the other participants in their memory for 'clean' and 'dirty' objects. However, the OCD-washers recalled more accurately the 'dirty' source of contamination than the 'clean' source. This result was specific to the OCD-washers, and suggests a memory bias for contextually threatening information. The differences between our findings and those published by Radomsky and Rachman's are discussed.     

Does social dominance generate prejudice? Integrating individual and contextual determinants of intergroup cognitions

Social dominance orientation (SDO) has been proposed as an important variable in the explanation of prejudice. We distinguish between three conceptualizations of SDO: SDO as a personality trait (personality model), SDO as a moderator of the effects of situational variables (Person x Situation model), and SDO as a mediator of the effect of social position on prejudice (group socialization model [GSM]). Four studies (N = 1.657) looking at the relations between social positions, SDO, and prejudice in a natural setting and in a laboratory setting provide strong support for the GSM. In contrast to previous correlational findings, there is evidence of a cause (dominant social position), an effect (prejudice increases), and a mediator (SDO). These results suggest new perspectives on the integration of individual and contextual determinants of prejudice.     

Towards a theory of collective phenomena. III: Conflicts and forms of power

This paper further develops a new theory of power advanced by the authors in two previous papers (Galam and Moscovici, 1991, 1994). According to this theory power results from the build up of conflicts within a group, these conflicts requiring a degree of organizational complexity which is itselfa decreasing function of group size. Within this approach, power appears to be a composite of three qualitatively different powers, institutional, generative and ecological. Levels and relationships among these forms of power are considered as a function of the diversity of the group. There exist also three states of organization associated with power evolution. At the group initial stage is the paradigmatic state. Creation and inclusion of conflicts are accomplished in the transitional state through the building of complexity. At a critical value of diversity, the group moves into the agonal state in which institutional power vanishes simultaneously with the fusion of generative and ecological powers.     

Contrary effects of group cohesiveness in minority influence: Intergroup categorization of the source and levels of influence

The roles of group cohesiveness and intergroup categorization of the source in minority influence were studied in a 2 (high versus low cohesiveness) × 2 (ingroup versus outgroup source) × 3 (phases) factorial design. Six subjects forming a group were confronted with a confederate defending a minority position in a perceptual task. The results indicated a manifest influence effect (slide colour), accompanied by a latent polarization (afterimage) in the high cohesrveness/outgroup source condition, and a latent unfluence effect in the low cohesiveness/ingroup source condition.     

Two-stage model of visual backward masking: Sensory transmission and accrual of effective information as a function of target intensity and similarity

A functional model is used to describe the effect of target intensity and target-set similarity on backward visual masking. The model consists of two distinct stages of visual information processing. The first stage is related to sensory transduction and transmission and is assumed to require a finite and measurable amount of time during which performance-remains at chance. The second stage, associated with central processing, is characterized by a negatively accelerated growth function reflecting the accrual of effective information. Results show that the duration of the transmission stage is inversely related to target intensity. Surprisingly, the rate of information accrual is an interactive function of both target intensity and target-set similarity. The pattern of results is consistent with the interpretation that both intensity and similarity mediate their effect through a common mechanism—the accrual of effective information.
