A case of persistent neurogenic stuttering following a missile wound

Observational criteria that have been proposed to distinguish developmental from neurogenic stuttering are critically reviewed. It is concluded that both conditions may closely resemble each other. As an example, a case of neurogenic stuttering following a missile would is reported.     

Attachement,solitude et détresse psychologique chez des jeunes adultes

La présente étude vise à examiner la nature des liens entre les styles d'attachement (sécurisant, anxieux/ambivalent et évitant), la solitude et la détresse psychologique (dépression, anxiété, agressivité et problèmes cognitifs) chez des jeunes adultes. L'échantillon se compose de 407 étudiants de niveau collégial dont l'âge moyen se situe à 18 ans. Les sujets doivent répondre à deux questionnaires d'évaluation du style d'attachement, à l'échelle de solitude UCLA, ainsi qu'à l'index de symptômes psychiatriques. Les résultats laissent voir que les individus ayant un style d'attachement sécurisant rapportent moins de symptômes de dépression et de sentiments de solitude que les sujets des styles anxieux/ambivalent et évitant. De même, ils vivent moins d'anxiété, d'agressivité et de problèmes cognitifs que les individus du style anxieux/ambivalent. Par ailleurs, les individus du style d'attachement anxieux/ambivalent sont plus déprimés, anxieux et agressifs que les individus du style évitant. Par contre, aucune différence significative ne ressort entre les sujets des styles d'attachement anxieux/ambivalent et évitant sur le plan des problèmes cognitifs et de la solitude. Des analyses de régression multiple montrent que l'attachement anxieux/ambivalent et la solitude expliquent un pourcentage significatif de la variance associée à la détresse psychologique. Enfin, il ressort que la solitude joue un rôle modérateur dans la relation unissant l'attachement non sécurisant et les problèmes de nature cognitive, alors qu'elle joue un rôle médiateur dans la relation entre l'attachement sécurisant, la dépression et l'anxiété.     

Cluttering after brain damage

On the basis of published cases and of observations made in two patients, a syndrome of acquired cluttering after brain damage in adults is delineated, and a hypothesis is presented regarding the patho-physiology of the disorder.     

Global predominance in object recognition: artefact or treatment rule?

This paper provides a critical evaluation of the idea that, relative to the identity of the parts (local aspect), the configuration of the parts (global aspect) is of special importance during perceptual analysis. The controversy surrounding the global precedence phenomenon (Navon, 1977) is reviewed. In particular, I evaluate and reject the hypothesis that global precedence is simply the product of the greater discriminability of the global aspect. Instead, I propose that one general rule characterizing preattentive perceptual processing is a broad categorization of global information. I present the empirical evidence supporting this model and suggest some direction for future studies.     

The Effects of Measurement Strategy on Attributions for Marital Problems and Behaviors1

The present study examined the relation of attributions for spouse behaviors, attributions for global conjugal conflict, and marital adjustment. The sample consisted of 74 French-Canadian couples who completed the Marital Attribution Style Questionnaire, the Conflict Rating Scale, and the Dyadic Adjustment Scale. Results showed that the relation between attribution and marital satisfaction is stable across culture. In addition, specific and general attribution measures were low to moderately correlated. However, multiple regression analyses demonstrated that attributions for global conjugal conflict entered the regression equations more often than attributions for hypothetical spouse behaviors. These findings suggest that the comparability of marital attribution measures should not be taken for granted. The need to develop standardized measures is underlined.     

Diurnal time courses in psychomotor performance and waking EEG frequencies

The present study examined the similarities between the diurnal time courses in the waking EEG activity and the psychomotor performance. The aim was to verify if some ongoing changes in the excitability of the cortical nerve cells across the daytime could facilitate the sensorimotor processing. EEG recordings and performance results for the Four Choice Reaction Time Test (FCRTT) were obtained every two hours, from morning to late evening period, in 8 young normal subjects (21.3 +/- 0.5 years). ANOVAs were used to verify the presence of diurnal variations in the two measures. Nonparametric correlations were obtained to test the similarity between the changes across the day in the two measures. Three EEG frequency bands (delta, sigma, and beta1) and the reaction time measures varied across the daytime. The changes in the sigma (12.00-13.75 Hz) and the beta1 (14.00-19.75 Hz) bands were similar to the diurnal variations in the reaction time measures. It is suggested that the changes in the sigma and the beta1 bands may facilitate the processing of the sensorimotor treatment.     

Development and validation of a brief version of the dyadic adjustment scale with a nonparametric item analysis model

The main purpose of the current research was to develop an abbreviated form of the Dyadic Adjustment Scale (DAS) with nonparametric item response theory. The authors conducted 5 studies, with a total participation of 8,256 married or cohabiting individuals. Results showed that the item characteristic curves behaved in a monotonically increasing function for all items of the brief 4-item version of the DAS (DAS-4). The DAS-4 proved to be informative at all levels of couple satisfaction. Compared with the 32-item version of the DAS (DAS-32), it was as effective in predicting couple dissolution and was significantly less contaminated by socially desirable responding. In addition, structural equation modeling demonstrated that the underlying latent construct measured by the DAS-4 was very stable over a 2-year period. This brief version has the advantage of being less time consuming and constitutes a promising alternative to the original DAS-32 for clinicians and researchers.     

Sinuosity and the Affect Grid: a method for adjusting repeated mood scores

Sinuosity is a measure of how much a travelled pathway deviates from a straight line. In this paper, sinuosity is applied to the measurement of mood. The Affect Grid is a mood scale that requires participants to place a mark on a 9 x 9 grid to indicate their current mood. The grid has two dimensions: pleasure-displeasure (horizontal) and arousal-sleepiness (vertical). In studies where repeated measurements are required, some participants may exaggerate their mood shifts due to faulty interpretation of the scale or a feeling of social obligation to the experimenter. A new equation is proposed, based on the sinuosity measure in hydrology, a measure of the meandering of rivers. The equation takes into account an individual's presumed tendency to exaggerate and meander to correct the score and reduce outliers. The usefulness of the equation is demonstrated by applying it to Affect Grid data from another study.     

Traduction et adaptation du TEI-SF afin de documenter l’acceptabilité sociale de l’intervention comportementale intensive

Early intensive behavioral intervention is more widely used in large-scale community-based services in Autism Spectrum Disorder. There is an increased need to evaluate the social acceptability of these programs. The present study used a measure of social acceptability as part of a social validation procedure to evaluate a community-based EIBI offered in inclusive childcare, as well as two focused interventions associated with this program. To do so, the Treatment Evaluation Inventory Short-form (TEI-SF) questionnaire was adapted and translated to French. The validation results for the TEI-SF, as well as for the social acceptability of the EIBI programs and procedures, are presented. The results are the first evidence of the validity of the TEI-SF (adapted and translated to French), presenting scores of validity of intervention and a favourable perspective related to the early intensive behavioral intervention and opening the door to further research.     

Behavioral disorganization in schizophrenia during a daily activity: the kitchen behavioral scoring scale

Executive dysfunction has been extensively described in schizophrenia and has been found to correlate with the negative symptoms of the disease. However, executive dysfunction is usually assessed by cognitive tests, and these are not necessarily good predictors of an individual's daily functioning. This study aimed to discover whether executive dysfunction in schizophrenia can be measured by analyzing a daily routine such as cooking a meal. Behavior was scored on the basis of the optimal sequence of macrostructures (order of dishes) and microsteps (order of actions) that must be performed to prepare the meal in a minimum of time and with the smallest delay between the completion of the first and last dishes. The results showed that patients with schizophrenia make macrostructure but not micro-step sequencing errors. The number of repetitions and omissions and the delay between the completion of the first and last dish were all greater in patients than in control subjects. In patients with schizophrenia, but not in normal controls, these behavioral malfunctions were significantly correlated with both negative symptoms and performance on the executive tasks. Poor performance on the memory tests was not correlated with the behavioral malfunction. Therefore, daily functioning in schizophrenia may be specifically influenced by executive dysfunction in schizophrenia, and this can be quantitatively assessed with a behavioral scale of action sequences.
