Theory of mind: is training contagious?

In this study, preschool children were successfully trained in theory of mind tasks, namely false belief inference and appearance–reality distinction. Results show that both types of training had a direct effect, as measured by the improvement of performance on the FB and AR delayed post‐tests. Both types of training also had an indirect effect, as measured by transfer of the benefits of the training to the task that was not in the training. Finally, both types of training were effective even when the children were trained in a task they had already mastered.     

Phonological similarity in free and serial recall: The effect of increasing retention intervals

The phonological similarity effect (or acoustic confusion effect) consists of poor serial recall performance for lists composed of similar‐sounding words compared to lists of dissimilar‐sounding items. Building on the work of Nairne and Kelley (1999), the extent to which this classical verbal short‐term memory effect changes over the course of a retention interval was investigated. The impact of the phonological similarity on memory performance over time was compared in three paradigms: order reconstruction, serial recall, and free recall. Participants were presented with two blocks of 15 lists composed of five monosyllabic words, one block containing phonologically similar words and the other phonologically distinct words. Recall occurred either after 2, 8, or 24 seconds retention interval filled with a digit shadowing task. Our results confirmed and extended those of Nairne and Kelley. In order reconstruction and serial recall tasks, a classical phonological similarity effect (i.e., decrement in performance with similar lists) was observed for the 2‐s retention interval. This effect disappeared after a brief period of digit shadowing (i.e., 8‐s delay) and a beneficial effect of similarity was observed for the 24‐s retention interval. In the free recall task, the phonological similarity produced better performance whatever the delay between presentation and recall. Those results are discussed in the light of Nairne's (1990a) feature model and confirm the role of item‐specific and inter‐item processes in order reconstruction, serial recall, and free recall. L'effet de similarité phonologique se manifeste par une performance de rappel plus faible lorsque les listes sont composées de mots dont la sonorité est proche que lorsque les mots sont de sonorité éloignée. Sur la base de la recherche de Nairne et Kelley (1999), nous nous sommes intéressés à la manière dont évolue cet effet classique de mémoire à court terme verbale dans le temps, C'est‐à‐dire à L'issue d'intervalles de rétention de durées variables. L'impact de la similarité phonologique sur la performance mnésique a été évaluée sur la base de trois paradigmes, la reconstruction de L'ordre, le rappel sériel et le rappel libre. Les participants ont été soumis à deux blocs de 15 listes comportant 5 mots monosyllabiques, un bloc comprenant des mots similaires phonologiquement et un bloc comprenant des mots dissimilaires phonologiquement. Le rappel est demandé après un intervalle de rétention d'une durée de 2, 8 ou 24 secondes durant lequel une tâche de shadowing de chiffres est proposée. Nos résultats confirment et étendent ceux obtenus par Nairne et Kelley. Pour les tâches de reconstruction de L'ordre et de rappel sériel, un effet de similarité phonologique classique (i.e., chute des performances pour les listes similaires) est observé avec un intervalle de rétention de 2 secondes. Cet effet disparaît après une courte période consacrée au shadowing de chiffres (i.e., 8 secondes) et un effet bénéfique de la similarité est observé pour un intervalle de rétention de 24 secondes. En rappel libre, la similarité phonologique provoque une amélioration des performances quel que soit le délai entre présentation et rappel. Ces résultats sont discutés à la lumière du modèle des traits de Nairne (1990a). Ils confirment le rôle des traitements spécifiques à L'item et des traitements inter‐items lors de tâches telles que la reconstruction de L'ordre, le rappel sériel et libre. El efecto de la similitud fonológica (o efecto de confusión acústica) se manifiesta en fallas en el recuerdo de series para las listas compuestas por palabras que tienen sonidos similares en comparación con aquéllas que poseen elementos distintos. Con base en el trabajo de Nairne en Kelley (1999), se investigó la medida en la que este efecto clásico de memoria reciente cambia a lo largo del curso de un intervalo de retención. El impacto de la similitud fonológica sobre el desempeño de la memoria a lo largo del tiempo se comparó en tres paradigmas, reconstrucción del orden, recuerdo de series y recuerdo libre. Se presentó a los participantes dos bloques de 15 listas compuestas por 5 palabras monosilábicas, un bloque contenía palabras fonológicamente similares y, el otro, palabras fonológicamente distintas. El recuerdo ocurrió después de un intervalo de retención de 2, 8 ó 24 segundos lleno de una tarea digital de sombreado. Los resultados confirmaron y extendieron los de Nairne en Kelley. En las tareas de reconstrucción del orden y en la recuerdo de series, se observó un efecto clásico de similitud fonológica para el intervalo de retención de 2 segundos (es decir, disminución de la ejecución con listas similares). Este efecto desapareció después de un breve periodo de sombreado digital (es decir, un retraso de 8 segundos) y se observó un efecto benéfico de similitud para el intervalo de retención de 24 segundos. En la tarea de recuerdo libre, la similitud fonológica produjo mejor ejecución independientemente del retraso entre la presentación y el recuerdo. Tales resultados se discuten a la luz del modelo de Nairne (1990a) y confirman el papel que desempeñan los procesos de reactivo específico e interreactivo en la reconstrucción del orden, y en el recuerdo de series y libre.     

A quantitative review of overjustification effects in persons with intellectual and developmental disabilities

The overjustification hypothesis suggests that extrinsic rewards undermine intrinsic motivation. Extrinsic rewards are common in strengthening behavior in persons with intellectual and developmental disabilities; we examined overjustification effects in this context. A literature search yielded 65 data sets permitting comparison of responding during an initial no‐reinforcement phase to a subsequent no‐reinforcement phase, separated by a reinforcement phase. We used effect sizes to compare response levels in these two no‐reinforcement phases. Overall, the mean effect size did not differ from zero; levels in the second no‐reinforcement phase were equally likely to be higher or lower than in the first. However, in contrast to the overjustification hypothesis, levels were higher in the second no‐reinforcement phase when comparing the single no‐reinforcement sessions immediately before and after reinforcement. Outcomes consistent with the overjustification hypothesis were somewhat more likely when the target behavior occurred at relatively higher levels prior to reinforcement.     

The Role Behavioral of Activation and Inhibition in Explaining Adolescents’ Game Use and Game Engagement Levels

According to Gray’s reinforcement sensitivity theory, variations in the functioning of two neuropsychological systems, the behavioral approach (BAS) and inhibition (BIS) system, can result in individual differences in personality. Several studies have looked at associations between personality and media use but media research integrating BAS and BIS is scarce. The current cross-sectional survey study (n = 1016) representative for Belgian adolescents investigated associations between BAS and BIS and game use and game engagement in adolescents. Results showed that BAS was positively associated with playing both violent and nonviolent games. BIS was negatively associated with violent game use while it was positively associated with nonviolent games. Also, BAS was positively associated with game engagement. No association was found between BIS and game engagement. Game engagement was shown to mediate the relationship between BAS and playing both violent and nonviolent games. Based on these results, the present study argues that integrating the reinforcement sensitivity theory in media research makes an important contribution to the understanding of the link between personality and game engagement and game use.     

Metamemory knowledge and beliefs in patients with schizophrenia and how these relate to objective cognitive abilities

Subjective reports and theories about memory may have an influence on other beliefs and behaviours. Patients with schizophrenia suffer a wide range of deficits affecting their awareness of daily life, including memory. With the Metamemory Inventory in Adulthood (MIA) we ascertained patients’ memory knowledge and thoughts about their own cognitive capacities and about several aspects of cognitive functioning: personal capacities, knowledge of processes, use of strategies, perceived change with ageing, anxiety, motivation and mastery. The participants’ ratings were correlated with their intellectual, cognitive and psychiatric data. Patients felt they had a lower capacity and marginally lower mastery over their memory than comparison subjects. They reported less recourse to strategies, and higher levels of memory-related anxiety. However, their knowledge of basic memory processes, motivation to succeed, and perception of ageing effects were similar. So patients with schizophrenia do not suffer a general and non specific impairment of their metacognitive knowledge.     

Bien-être à la retraite selon le genre et l’âge : lien avec la perception du travail ancien

We focused on the direct relationship between job satisfaction experienced during working life and life-satisfaction after retirement. Also we wonder on differences about aspects of the former work evoked as pleasant. These questions are treated by differentiating women and men perceptions, and the perceptions according to age. Data on 396 French subjects, 182 men and 214 women (age range 66 to 98) were used to examine how life-satisfaction in retirement is linked to the perception of former job satisfaction. Other indications of adaptation are retained, as self-esteem or conversely boredom. Results show a) that job satisfaction is a predictable variable for life-satisfaction after retirement, b) that this impact is weaker for youngest, c) a strong similarity between men and women, whatever is their age. We discuss observed links.     

Intolerance to delayed reward in girls with multiple suicide attempts

Impulsivity has been conceptualized as influencing the expression of suicidal behavior. Adolescence is a developmental period characterized both by a relatively high rate of suicide attempts and a high level of impulsivity. The current study examined two behavioral measures (delay reward and disinhibition) and one self-report measure of impulsivity among girls with suicide attempt histories. Girls with multiple suicide attempts performed more impulsively on measures of delayed reward, and had higher self-ratings of depression and aggression than girls with either one or no suicide attempts. The multiple attempter girls' preference for immediate gratification may directly increase vulnerability to suicidal acts in the context of distressing states or indirectly increase risk by creating poor life experience over time.     

Human values priorities: effects of self-centredness and age

This study aims to assess the effects of the degree of self-centredness/selflessness and age on human values priorities according to Schwartz model. This model displays two main dimensions which oppose on one hand, self-enhancement to self-transcendence and on the other hand, openness to change to conservation. The sample consisted of 307 adults aged 18 to 65 who filled in two questionnaires: the Self-Transcendence Inventory (STI) and the Questionnaire of Values by Portraits (QVP). The results show that the more people were selfless, the more they gave greater importance to self-transcendence and less importance to self-enhancement; and inversely. Moreover, the older the participants were, the more they valorised collective values compared to individual values. Finally, age appeared as a more relevant predictor of values priorities than the degree of self-centredness. Such results could be of first importance in terms of designing moral education strategies.
