ETUDE COMPARATIVE DES EVALUATIONS COLLECTIVES ET INDIVIDUELLES DE LA PENSEE FORMELLE

The purpose of the present study is to examine the effects of different individual and group testing procedures on the success rate obtained by subjects on different formal problems. Four testing conditions were compared: a clinical interview; an individual interview without intervention; a group test with a demonstration of the material; and a group paper-and-pencil test. The four conditions are defined according to several variables that were deemed important for the explanation of potential performance outcomes. All subjects were administered the following four Piagetian derived tasks: a projection of shadows task; a permutation task; an equilibrium in the balance task; and an interrupter combinations task. According to the general hypothesis, subject performance should be optimal for the clinical interview and decline gradually as the assumed advantages of this method are systematically removed, i.e., counterquestioning of the examiner, retrials, subject-examiner interactions, familiarization with the material, etc. The results show that there are performance differences between the conditions, but mainly across the individual and group situations. However, mean ranks obtained from each condition indicate that the facilitating variables identified in the first three conditions have a certain influence on subject performance. Implications regarding a choice of a valid mesurement of formal thought are discussed.     

Acquired stuttering

Working from a case of degeneration of the nervous system accompanied by stutterlike repetitions, this article raises the question whether patients should be said to have acquired stuttering when they evidence only one of the typical symptoms of the syndrome. On the other hand, it is shown that when acquired stuttering is polysymptomatic, it can hardly be distinguished from developmental stuttering on the basis of the patient's verbal behavior. This may have important medicolegal implications. When acquired stuttering occurs in the context of aphasia, both affections appear to be relatively independent of each other. Specifically, there seems to be no causal relationship between them.     

Induction of a transient dysexecutive syndrome in Parkinson's disease using a~subclinical dose of scopolamine

Parkinson's Disease (PD) is often associated with a subcortico-frontal syndrome (SCFS) that is mainly characterized by executive dysfunctions. The complete biochemistry of these dysfunctions remain misunderstood although many studies have suggested a role of the dopaminergic lesions. However, cholinergic lesions in this disease may also account for the SCFS occurrence. The present study has assessed the effects of an acute subclinical dose of scopolamine in normal controls and in PD patients who were devoid of cognitive deficit. Results indicates that PD patients but not normal controls developed a transient SCFS for the duration of the drug action. In contrast to other populations with cholinergic depletions - such as Alzheimer's disease - cholinergic blockage in PD exacerbates specifically the dysexecutive syndrome without inducing amnesia or sedation. Such a discrepancy between these two neuropsychological profiles are discussed in terms of the specificity of the underlying cholinergic lesions.     

L'évaluation subjective directe des émotions ressenties au sein du couple

This present study examined the relationship between interpersonal affects, personality, psychological distress, attachment and marital adjustment. More specifically, we hypothesized that the inclusion of a direct subjective evaluation of interpersonal affects would add to our understanding of marital adjustment, even when other variables (personality, psychological distress, attachment) are being taken into account. The sample included 204 heterosexual French Canadian married or cohabiting couples. Results showed that women experienced more feelings of insecurity, unfairness, depreciation and powerlessness than men. Also, individuals who were less satisfied with their marriage reported more feelings of insecurity, unfairness, depreciation and powerlessness.     

Developing a generic approach to online automated analysis of writing and drawing tests in clinical patient profiling

Writing and drawing tests are widely used in the clinical environment for the diagnosis of a variety of neuropsychological conditions. Conventional assessment of these tests involves the inspection by trained assessors of the completed patient response. This article describes the development of a computer-based framework for data capture, automated feature analysis, and result reporting for a range of drawing- and writing-based test batteries. In developing this framework, we have exploited the commonality between tasks while allowing for both flexibility in configuration across condition-specific testing requirements and extensibility for future test development. Using the two example clinical conditions of visuospatial neglect and dyspraxia, we illustrate the advantages of utilizing a computer-based analysis system, describe a structured approach to system implementation, and demonstrate the generality of this implementation for different conditions of interest, which extends to feature selection and design.     

Obsessive Passion: A Compensatory Response to Unsatisfied Needs

The present research investigated the role of two sources of psychological need satisfaction (inside and outside a passionate activity) as determinants of harmonious (HP) and obsessive (OP) passion. Four studies were carried out with different samples of young and middle‐aged adults (e.g., athletes, musicians; total N = 648). Different research designs (cross‐sectional, mixed, longitudinal) were also used. Results showed that only a rigid engagement in a passionate activity (OP) was predicted by low levels of need satisfaction outside the passionate activity (in an important life context or in life in general), whereas both OP and a more favorable and balanced type of passion, HP were positively predicted by need satisfaction inside the passionate activity. Further, OP led to negative outcomes, and HP predicted positive outcomes. These results suggest that OP may represent a form of compensatory striving for psychological need satisfaction. It appears important to consider two distinct sources of need satisfaction, inside and outside the passionate activity, when investigating determinants of optimal and less optimal forms of activity engagement.     

Eliminating flanker effects and negative priming in the flankers task: evidence for early selection

Reports of negative priming in the absence of flanker effects (Fox, 1995) provide support for the notion that unattended stimuli are identified. I evaluated the hypothesis that such results are the outcome of attentional leakage to the flanker location. In Experiment 1, I assessed flanker effects and negative priming as a function of target-flanker proximity (.9 degrees and 2.7 degrees for near and far flankers, respectively) and of attention cuing to the target location (precued vs. uncued) on the prime trials. I report larger flanker effects in uncued than in precued conditions, and larger effects for near than for far flankers. More critically, when attention was precued, both flanker effects and negative priming vanished for far flankers. In Experiment 2, I show that the latter result was not linked to prime-probe contextual similarity (Neill, 1997). These results demonstrate that selective target processing is possible when attention is optimally focused to the target location.     

Global Dominance Outside the Focus of Attention

Identification of the local aspect of a relevant compound stimulus has been found to be delayed by the presence of target-set members at the global aspect of an irrelevant compound stimulus, whereas identification of the global aspect is unaffected by the presence of local target-set members within the irrelevant object (Paquet & Merikle, 1988). This effect has been termed the global category effect , and it suggests that global dominance occurs for objects located outside the attentional focus, as well as within an attended hierarchical object. In the present experiments, attention was directed to the relevant one of two compound stimuli by using either shape information (Experiments 1 and 2) or a 100-msec peripheral rapid onset precue (Experiment 3). Results revealed a global category effect even when the physical features of the displays containing global target-set members within the irrelevant object were closely matched with those of the control displays. Critically, the magnitude of the global category effect was affected by how well attention could be focused on the relevant compound stimulus. These findings suggest (a) that the analysis of global information for irrelevant objects is more elaborate than the simple detection of features; and (b) that both perceptual and attentional mechanisms are involved in global dominance.
