Players’ Gender and Male Referees’ Decisions About Aggression in French Soccer: A Preliminary Study

The aim of this study was to examine (a) aggression displayed by players and (b) referees decisions about these behaviors as a function of the gender of the players in French soccer. Twenty-six games (13 for women and 13 for men) were videotaped. Instrumental aggressive acts and referees decisions were then observed. The findings indicated a significant effect of gender on instrumental aggression and referees decisions related to these behaviors. Male players displayed more instrumental aggressive acts than female players did. Nevertheless, relative to the total number of aggressive acts displayed, referees penalized women more than men. Gender stereotypes might be a relevant explanation for these results, as soccer is generally perceived as a masculine-type sport, particularly in France, and aggression as a masculine characteristic.     

Development of flexible visual recognition memory in human infants

Research using the visual paired comparison task has shown that visual recognition memory across changing contexts is dependent on the integrity of the hippocampal formation in human adults and in monkeys. The acquisition of contextual flexibility may contribute to the change in memory performance that occurs late in the first year of life. To assess this skill, the images are presented on a background of one colour during familiarization and on a different coloured background during the recognition test. Our research showed that recognition memory is impaired by a change in context at 6 and 12 months of age but is unaffected at 18 and 24 months of age. The findings are discussed in relation to hippocampal development and the proposed developmental step in memory at 9-10 months of age.     

An additive factor analysis of the effect of depression on the reaction time of old patients

Depressed participants display longer reaction times (RTs) than control participants. The present study was aimed at deciphering which stages of processing are affected by depression in old adults. Sixteen old depressed patients and 16 old healthy volunteers performed a two-choice visual RT task. Signal intensity, stimulus-response mapping and foreperiod duration were manipulated so as to affect the stages of stimulus preprocessing, response selection and motor adjustment, respectively. Reaction time data suggest that depression spares the stage of stimulus preprocessing but affects the stage of motor adjustment. An analysis of the error rate leaves open the possibility that depression alters the stage of response selection.     

Age-related differences in the visual processes implied in perception and action: distance and location parameters

The aim of the two present experiments was to examine the ontogenetic development of the dissociation between perception and action in children using the Duncker illusion. In this illusion, a moving background alters the perceived direction of target motion. Targets were held stationary while appearing to move in an induced displacement. In Experiment 1, 30 children aged 7, 9, and 12 years and 10 adults made a perceptual judgment or pointed as accurately as possible, with their index finger, to the last position of the target. The 7-year-old children were more perceptually deceived than the others by the Duncker illusion but there were no differences for the goal-directed pointing movements. In Experiment 2, 50 children aged 7, 8, 9, 10, and 11 years made a perceptual judgment or reproduced as accurately as possible, with a handle, the distance traveled by the target. Participants were perceptually deceived by the illusion, judging the target as moving although it was stationary. When reproducing the distance covered by the target, children were unaffected by the Duncker illusion. Our results suggest that the separation of the allocentric visual perception pathway from the egocentric action pathway occurs before 7 years of age.     

The cognitive, emotional, and social impacts of the September 11 attacks: group differences in memory for the reception context and the determinants of flashbulb memory

The authors examined group differences in memories for hearing the news of and reactions to the September 11 attacks in 2001. They measured memory for reception context (immediate memory for the circumstances in which people first heard the news) and 11 predictors of the consistency of memory for reception context over time (flashbulb memory). Shortly after 9/11, a questionnaire was distributed to 3,665 participants in 9 countries. U.S. vs. non-U.S. respondents showed large differences in self-rated importance of the news and in memory for event-related facts. The groups showed moderate differences in background knowledge and emotional-feeling states. Within non-U.S. groups, there were large differences for emotional-feeling states and moderate differences for personal rehearsal, background knowledge, and attitudes toward the United States. The authors discuss the implications of those findings for the study of group differences in memory and for the formation of flashbulb memories.     

Mental rotation in schizophrenia

Motor imagery provides a direct insight into action representations. The aim of the present study was to investigate the level of impairment of action monitoring in schizophrenia by evaluating the performance of schizophrenic patients on mental rotation tasks. We raised the following questions: (1) Are schizophrenic patients impaired in motor imagery both at the explicit and at the implicit level? (2) Are body parts more difficult for them to mentally rotate than objects? (3) Is there any link between the performance and the hallucinating symptom profile? The schizophrenic patients (n = 13) displayed the same pattern of performance as the control subjects (n = 13). More particularly, schizophrenic patients’ reaction time varied as a function of the angular disparity of the stimuli. On the other hand, they were significantly slower and less accurate. Interestingly, patients suffering from hallucinations made significantly more errors than non-hallucinatory patients. We discussed these latter results in terms of deficit of the forward model. We emphasized the necessity to distinguish different levels of action, more or less impaired in schizophrenia.     

A study of impaired judgment of eye-gaze direction and related face-processing deficits in autism spectrum disorders

The purpose of this study was to examine whether individuals with autism spectrum disorders (ASD) use the same cognitive strategies as typically developing individuals when processing eye-gaze direction. Subjects viewed pictures of whole faces, the eye region alone, and pairs of arrows presented for 40, 70, or 100 ms, and responded according to the direction the eyes were looking or the arrows pointing (left, right, or straight ahead). Experiment 1 demonstrated that typically developing adults (n = 41) were more accurate and showed shorter reaction times when judging direction of averted eye gaze in the context of the whole face than when only the eyes were visible (eye-region-alone condition). Furthermore, in the eye-region-alone condition participants were more accurate and faster at judging direct eye gaze than averted eye gaze. The same task was used in experiment 2 to compare the performance of a group of individuals with ASD (n = 24) with that of a group of IQ-matched typically developing individuals (n = 26). The performance of the control participants was identical to that observed in experiment 1. Individuals with ASD were able to judge eye-gaze direction accurately at short exposure duration; however, they failed to show the typical advantage for judging averted gaze in whole faces and the increased sensitivity to direct gaze in the eye-region-alone condition. The findings are discussed in terms of impairments to discrete gaze-processing and face-processing mechanisms, and the connectivity between these mechanisms.     

Constraining the comprehension of pronominal expressions in Chinese

This paper reports a series of self-paced reading time experiments designed to probe how the reference of pronominal expressions is resolved on-line in (Mandarin) Chinese. It is assumed that pronoun resolution is achieved by narrowing the candidate set of potential antecedents for a pronoun. The experimental evidence reported here indicates that two factors--syntactic prominence and the matching of lexical features (e.g. gender)--play a significant role in filtering this candidate set. It is shown that syntactic prominence and feature matching work in conjunction with each other rather than in a competitive, winner-take-all manner. Furthermore, the evidence suggests that syntactic prominence is sensitive to structural relations rather than exclusively to grammatical functions (such as subject and direct object) or semantic roles (such as agent and patient) as has been assumed in the psycholinguistic literature.
