The effect of a textured visual field on modality dominance in a ventriloquism situation

Despite the often encountered affirmation that vision completely dominates other modalities in intersensory conflict, there are cases where discordant auditorv information affects the localization of a visual signal. Experiment I shows that “auditory capture” occurs with a visual input reduced to a single luminous point in complete darkness, but not with a textured background. The task was to point at a flashing luminous point alternately in the presence of a synchronous sound coming from a source situated 15° to one side (“conflict trials,” designed to measure immediate reaction to conflict) and in its absence (“test trials,” to measure aftereffects). Adaptive immédiate reactions and aftereffects were observed in the dark, but not with a textured background. In Experiment II, on the other hand, “visual capture” of auditory localization was observed at the levels of both measures in the dark and with the textured background. That visual texture affects the degree of auditory capture of vision, but not the degree of visual capture of audition was confirmed at the level of aftereffects in Experiment III, where bisensory monitoring was substituted for pointing during exposure to conflict. The empirical finding eliminates apparent contradictions in the literature on ventriloquism, but cannot itself be explained in terms either of relative accuracy of visual and auditory localization or attentional adjustments.     

LE CARACTÈRE TOPOLOGIQUE DES PREMIÈRES REPRÈSENTATIONS SPATIALES DE l'ENFANT

The topological nature of the child's early spatial representations. Piaget's hypotheses revisited. — Three experiments bearing on Piaget's hypotheses on the topological nature of the child's early concepts of space are reported. The results of the first experiment, replicating Piaget's stereognostic technique on a larger scale, were shown to confirm the earliness of topological discriminations, but it was found also that some simple Euclidian discriminations (curvilinear vs rectilinear, indented vs non-indented forms) were not more difficult. The second experiment has shown that the child relied rather on topological than on simple Euclidian attributes when both types of attributes were presented in a conflictual situation; otherwise, the simple Euclidian discriminations were easier. In a third experiment, using a drawing technique along with visual exploration, topological discriminations proved easier than Euclidian discriminations in one instance only (open-closed vs curvilinear-rectilinear forms). It is suggested in conclusion that the child's early discriminations are not based on topology as such, but on certain geometrical properties which are fundamental to topology itself.     

The Measurement of Organizational Citizenship Behavior: Are We Assuming Too Much?

Organizational citizenship behavior (OCB) is assessed by measuring how frequently employees display extra-role and discretionary behaviors. One hundred forty-four managerial employees responded to an OCB scale and indicated the number of behaviors on the scale they believed to be formally evaluated. None of the behaviors were believed to be unevaluated by all employees. Data suggest that a typical OCB scale is not measuring citizenship behaviors for everybody, and that OCB measurement needs refinement. Best prediction of other organizational variables was obtained when both the OCB and an index of "unevaluated" behaviors were used as predictors. Supervisor fairness interacted with OCB when predicting organizational commitment, and this interaction was contingent on the extent OCBs were believed to be unevaluated.

Autonomy, competence, and social relatedness in task interest within project-based education

To prepare students for instructive collaboration, it is necessary to have insight into students' psychological needs and interest development. The framework of self-determination theory was used to conduct a field experiment involving 114 students in vocational education. These students followed a practical business course which required they work in small learning groups. During the course, students were asked to complete the Quality of Working in Groups Instrument, an online measure of how strong autonomy, competence, social relatedness, and task interest are fulfilled. SEM showed that students' psychological needs were jointly and uniquely related to task interest over time. The significance of this on-line test for the assessment of interest within project-based education is discussed.     

Responses to Conflict and Cooperation in Adolescents with Anxiety and Mood Disorders

This study examined patterns of behavioral and emotional responses to conflict and cooperation in adolescents with anxiety/mood disorders and healthy peers. We compared performance on and emotional responses to the Prisoner’s Dilemma (PD) game, an economic exchange task involving conflict and cooperation, between adolescents with anxiety/depressive disorders (A/D) (N=21) and healthy comparisons (n = 29). Participants were deceived to believe their co-player (a pre-programmed computer algorithm) was another study participant. A/D adolescents differed significantly from comparisons in patterns of play and emotional response to the game. Specifically, A/D participants responded more cooperatively to cooperative overtures from their co-players; A/D girls also reported more anger toward co-players than did comparison girls. Our findings indicate that A/D adolescents, particularly females, respond distinctively to stressful social interchanges. These findings offer a first step toward elucidating the mechanisms underlying social impairment in youth with internalizing disorders. This research was supported by the Intramural Research Program of the NIH, NIMH.

Profiles of adversity and resilience resources: A latent class analysis of two samples

Adversities refer to events that are characterized by perceived or actual threat to human functioning. Often considered deleterious for health and well-being, recent work supports an alternative picture of the effects of adversity on human functioning, such that a moderate amount of adversity – when compared with none or high levels – can be beneficial. We extend this body of work in the current study by considering the breadth or type of adversities experienced simultaneously (referred to as polyadversity), with a focus on individual profiles of lifetime adversities. Latent class analysis was employed to explore different configurations of lifetime adversity experiences in two independent samples and examine how these latent classes differed with regard to resilience resources (i.e., optimism, hope, self-efficacy, and bounce-back ability). University students (N = 348) and members from the broader community (N = 1,506) completed measures of lifetime adversity exposure and resilience resources. Three polyadversity classes were revealed in each sample, with both producing a high and a low polyadversity class. The third class differed between samples; in the student sample, this class represented experiences of vicarious adversity, whereas in the community sample, it represented moderate levels of exposure to adversity. Support for the adaptive nature of a moderate amount of adversity exposure was found in the community sample but not in the student sample. This study produces initial evidence of how lifetime adversity experiences group together and how class membership is related to resilience resources.
