Assessment of Functional Impairment in Spanish Children

Le pressent travaux vérifie l’applicabilité et la validité du CAFAS, un instrument pour évaluer l’incapacité fonctionnel dans une population espagnole. L’échantillon est formé par 441 malades ambulatoires psychiatriques d’entre 8 et 17 années et leurs parents, et aussi par un échantillon de 74 malades ambulatoires pédiatriques. On a applique différents instruments pour évaluer l’incapacité fonctionnel, la psychopathologie, et autres variables psychologiques. La fiabilité intra observateur varie entre modérée et bonne. L’accord entre les ponctuations obtenues avec l’information des parents et des infants varie entre faible et modérée. Les corrélations avec autres mesures d’incapacité et du fonctionnement sont significatives mais modérée. Les ponctuations CAFAS différencient significativement les enfants avec et sans psychopathologie. Les résultats obtenus avalisent l’utilisation du CAFAS pour les études en psychopathologie, en incapacité fonctionnel et pour planifier interventions et services de santé mental. The present work tests the applicability and validity of the CAFAS, an instrument for assessing functional impairment, in the Spanish population. The sample included 441 psychiatric outpatients from 8 to 17 years old and their parents, and a pediatric group of 74 outpatients. Different instruments for assessing functional impairment, psychopathology, and other related variables were used. Interrater reliability ranged from moderate to very good. Weak‐to‐moderate agreement between CAFAS scores based on information from parents and children was obtained. Correlations with other measures of impairment and functioning were moderate. CAFAS scores differentiated significantly between children with and without psychopathology. These results permit the use of the instrument for studies on psychopathology and functional impairment, and for planning intervention and mental health services.     

Motion aftereffect of combined first-order and second-order motion

When, after prolonged viewing of a moving stimulus, a stationary (test) pattern is presented to an observer, this results in an illusory movement in the direction opposite to the adapting motion. Typically, this motion aftereffect (MAE) does not occur after adaptation to a second-order motion stimulus (i.e. an equiluminous stimulus where the movement is defined by a contrast or texture border, not by a luminance border). However, a MAE of second-order motion is perceived when, instead of a static test pattern, a dynamic test pattern is used. Here, we investigate whether a second-order motion stimulus does affect the MAE on a static test pattern (sMAE), when second-order motion is presented in combination with first-order motion during adaptation. The results show that this is indeed the case. Although the second-order motion stimulus is too weak to produce a convincing sMAE on its own, its influence on the sMAE is of equal strength to that of the first-order motion component, when they are adapted to simultaneously. The results suggest that the perceptual appearance of the sMAE originates from the site where first-order and second-order motion are integrated.     

Coping assessment in adolescents

The aim of this work was to obtain an abridged form of the Adolescent Coping Scale (Spanish version) that included items representative of the various factorial dimensions identified as stable. The scale (80 items) was administered to 800 Argentine adolescents. Factor analyses, principal axes and oblimin solution, were performed. An abridged scale was obtained, consisting of 46 items that were grouped into 11 dimensions: Cognitive Redefinition, Self-Blame, Fatalism, Evasion Through Amusement, Problem-Focused Coping (which includes requests for information and action), Evasion Through Physical Activity, Emotional Support, Emotional Discharge and Somatization, Anxiety, Isolation, and No Action. The reliability coefficients were found to be satisfactory.     

Application of Herek's attitudes toward lesbians and gay men scale in The Netherlands

A national sample of 921 respondents from the Dutch population completed the translated, slightly modified version of Herek's Attitudes Toward Lesbians and Gay Men Scale, originally developed in the USA for the assessment of attitudes toward lesbians and gay men. The present study was the first attempt to test the applicability of the scale in the Netherlands. In line with previous American findings, all scale items loaded highly on one factor. The scores also correlated with another measure of attitudes toward lesbians and gay men, namely, 'denial of equal rights' (r = .76), and with 'traditional view of women' (r = .48), 'importance of traditional marriage' (r = .53), and 'authoritarianism' (r = .31). Data support the scale's acceptable reliability and construct and discriminant validity.     

Object-based attentional selection can modulate the Stroop effect

The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In three experiments, participants had to name the color of one of two superimposed rectangles and to ignore words that appeared in the relevant object, in the irrelevant object, or in the background. The words were congruent, neutral, or incongruent with respect to the correct color response. Words in the irrelevant object and in the background produced significant Stroop effects, consistent with earlier findings. Importantly, however, words in the relevant object produced larger Stroop effects than did the other conditions, suggesting amplified processing of all the features of an attended object. Thus, object-based processing can modulate the Stroop effect.     

The role of injection cues in the associative control of the US pre-exposure effect in flavour aversion learning

Two experiments, using rats as subjects, examined the role of contextual cues in producing the unconditioned stimulus (US) pre-exposure effect in conditioned taste aversion. Experiment 1 showed a significant US pre-exposure effect, when the pre-exposure was conducted in a familiar context, and that a change of context between the pre-exposure and conditioning phases did not attenuate this effect. Experiment 2 demonstrated that extinction of injection-related cues after the pre-exposure stage attenuated the US pre-exposure effect, when the pre-exposure was conducted in either a familiar or a novel context. Taken together, these results support the associative explanation of the US pre-exposure effect in terms of blocking, incorporating a role for injection-related cues in the context blocking analysis of the US pre-exposure effect.
