Achievement goals and engagement in individual and collective learning activities

The relationship between achievement goals and individual and collective learning activities was examined for 290 university students who completed two questionnaires. One assessed three achievement goals-a mastery goal and two performance goals, namely, approval seeking and advancing. The other questionnaire measured how actively students report engaging in individual and collective learning activities. Regression analyses showed that the adoption of mastery goals was associated with active engagement in both individual and collective learning, while adoption of a performance goal of approval seeking was associated with passive engagement in individual learning activities. These results are discussed in relation to their theoretical implications and in regard to the possible moderating effect of protecting self-worth.     

Clearing the air: identity safety moderates the effects of stereotype threat on women's leadership aspirations

Exposing participants to gender-stereotypic TV commercials designed to elicit the female stereotype, the present research explored whether vulnerability to stereotype threat could persuade women to avoid leadership roles in favor of nonthreatening subordinate roles. Study 1 confirmed that exposure to the stereotypic commercials undermined women's aspirations on a subsequent leadership task. Study 2 established that varying the identity safety of the leadership task moderated whether activation of the female stereotype mediated the effect of the commercials on women's aspirations. Creating an identity-safe environment eliminated vulnerability to stereotype threat despite exposure to threatening situational cues that primed stigmatized social identities and their corresponding stereotypes.     

Effects of visual attentional load on low-level auditory scene analysis

The sharing of processing resources between the senses was investigated by examining the effects of visual task load on auditory event-related brain potentials (ERPs). In Experiment 1, participants completed both a zero-back and a one-back visual task while a tone pattern or a harmonic series was presented. N1 and P2 waves were modulated by visual task difficulty, but neither mismatch negativity (MMN) elicited by deviant stimuli from the tone pattern nor object-related negativity (ORN) elicited by mistuning from the harmonic series was affected. In Experiment 2, participants responded to identity (what) or location (where) in vision, while ignoring sounds alternating in either pitch (what) or location (where). Auditory ERP modulations were consistent with task difficulty, rather than with task specificity. In Experiment 3, we investigated auditory ERP generation under conditions of no visual task. The results are discussed with respect to a distinction between process-general (N1 and P2) and processspecific (MMN and ORN) auditory ERPs.     

Sensory effects on judgments of short time-intervals

Two experiments were conducted to test the effect of nontemporal factors on duration discrimination. In Exp. 1, a forced-choice adaptive procedure with a standard duration of 400 or 800 ms was employed. It was shown that, for both auditory and visual modes, the discrimination is better with empty intervals (a silent period between two brief signals) than with filled intervals (a continuous signal), but only with shorter durations. In a second experiment, where intervals of the same duration range were employed but were presented with a single-stimulus method, discrimination was better with empty than with filled intervals, and this effect applied to both ranges of duration and both sensory modes. In both experiments, discrimination was better in the auditory than in the visual mode. These data are discussed in the context of current models of timing mechanisms.

Erroneous Perceptions in Generating Sequences of Random Events1

This paper reports the results of 2 studies that examine the perceptions of individuals attempting to generate random sequences. It was hypothesized that erroneous perceptions dominate probability judgment. The first study demonstrated that subjects verbalized significantly more erroneous than accurate perceptions when generating sequences of random binary events. The second study was designed both to replicate these data and to assess the role of motivation on the frequency of misconceptions. Results showed that the total number of erroneous perceptions again outnumbered accurate perceptions but, motivation did not increase the number of misconceptions. A basic error concerned subjects' inability to consider events as being independent of each other. The theoretical and practical implications of these results are discussed in relation to the psychology of gambling.     

Macroscopic marital interaction coding systems: Are they interchangeable?

The present study sought to determine the convergent validity of two macroscopic marital interaction coding systems: the Marital Interaction Coding System-Global and the Global Couple Interaction Coding System. The sample consisted of 40 couples who completed the Dyadic Adjustment Scale, the Potential Problem Checklist and a 30-min problem solving interactional task. Filmed interactions were coded by separate teams of observers using the Marital Interaction Coding System-Global and the Global Couple Interaction Coding System. Results showed that interobserver agreement, as assessed through intraclass correlations, was satisfactory for both coding systems. Between-system comparisons revealed that convergent validity coefficients were moderate; thus, it seems premature to conclude that macroscopic coding systems are interchangeable. Finally, multiple regression analyses indicated that both systems contained significant non-redundant behavioral predictors of marital adjustment. Implications of these results are discussed.     

Kindergarten predictors of boys' stable behavior problems at the end of elementary school

This study predicted stable social maladjustment at ages 10, 11, and 12 from teacher behavioral ratings in kindergarten and a measure of family demographics. Kindergarten teachers rated 1,034 boys on hyperactivity, aggression, inattention, anxiety–withdrawal, and prosocial behavior. Sociodemographic information was collected from the parents. At ages 10, 11, and 12, teacher, parent, peer, and self-report behavior ratings were collected on 743 boys. School achievement was documented from school records. Boys whose average scores on each of the five behavioral ratings across ages 10, 11, and 12 were above the 90th percentile according to at least two informants were defined as having stable behavioral problems. From teacher ratings collected in kindergarten and family demographics, logistic regression analyses predicted stable social maladjustment. For each negative outcome there was a unique set of predictors. The results are discussed with reference to the early identification of children who are at risk.This research was supported by a grant from the Conseil Québécois de la Recherche Sociale.

Grammatical analysis and logical analysis in France

It is well known that, in France, this important movement, which originated in Port-Royal, did not remain exactly on the same basis during its development. In this paper we attempt to show how a new concept (the logical analysis of sentence from phrase) was proposed by Du Marsais (see grammatical articles of the Encyclopédie), Beauzée (1767) and, finally, Letellier (1805, 1811).
