Développement de la mémoire de travail : relations du centre exécutif avec la boucle phonologique et le calepin visuospatial chez des enfants de CE1 et de CM2

The aim of this study was to examine the development of working memory's components and their relationships. Phonological loop's, visuospatial sketchpad's and central executive's efficiencies were assessed by simple and complex span tasks and executive tasks with verbal and visuospatial material. The analyses were performed on 64 second-grade and 55 fifth-grade children's data. Developmental performances improvement was examined according to tasks and material. Analyses of variance revealed performances improvement according to age and type of material (verbal > non verbal) for the slave system tasks and for a part of central executive's tasks. Correlation analysis and exploratory factorial analysis suggested that slave systems would become progressively more specific and that central executive's efficiency would be dependent on this specialization.     

Effets de la pression temporelle sur les estimations de durées

This study aims at examining the effects of time pressure on adults’ time estimation. Participants had to solve mazes under two conditions of time pressure (with/without). After each maze, they had to estimate the time elapsed since the beginning of maze solving. Results show that under time pressure, participants 1) overestimated the duration of maze solving and 2) were less variable in their time estimation, in comparison to the condition without time pressure. These results are discussed in the framework of temporal information processing model.     

Développement de la connaissance des lettres capitales. Étude transversale chez les enfants français de trois à six ans

The present study examined the knowledge of uppercase letters in 160 children aged from three to six. Three tasks were administrated: letter saying, letter naming, letter recognition. Children's responses were analyzed according to several variables: school level, gender, task, letter type, letter frequency, etc. Letter knowledge improved from three to six years, but with huge differences among children, namely the superiority of girls over boys. Letter by letter analyses showed that scores were highly consistent between tasks and school levels. They also revealed that letter knowledge was affected by letter type, letter frequency, alphabetic rank and the presence of letters in the child's first name. The findings are discussed for their contribution to the understanding of letter learning.     

Directives anticipées et autonomie de la personne en fin de vie

Advance directives are an instrument used to maintain patients autonomy in case they can no longer decide themselves, according to French law « patients rights and end of life ». However, analysis of the legal procedure does not lead to such a conclusion.     

Évolution des idées en psychologie de la santé dans le monde anglo-saxon. De la psychologie de la santé (health psychology) à la psychologie critique de la santé (critical health psychology)

The authors adopt a historical perspective and exhibit the debates held within Health Psychology in the Anglo-Saxon universe since the 1980s. They show how the development of the North-American mainstream approach has aroused several objections. These objections were firstly methodological (qualitative methods) then, theoretical and epistemological. This evolution has allowed the creation of two main approaches: Qualitative Health Psychology and Critical Health Psychology. While this course is not yet well-known in France, it illustrates, however, the present developments and the richness of the discussion within Anglo-Saxon Psychology. The conclusion shows that these debates should be known and accepted if we intend to improve our models in Psychology, so that they take into account the situated nature of the human being, its dynamics, its temporality as well and its complexity. Hence, Health Psychology perspectives as a whole will gain in pertinence in the fields of research and intervention.     

Schémas cognitifs, croyances addictives et défenses dans la consommation et l’addiction au cannabis de jeunes adultes

Theoretical background

Integrating the cognitive approaches based on the model of Beck et al. (1993) information treatment, the Young (1994) model of maladapted schemas, the integrative approach of Plutchik (1995) and the clinical approach based on defense mechanisms (Bond, 1995), this study aimed at investigating: (a) the role of the hyperactivated maladapted schemas, (b) the addictive beliefs, (c) the suractivation of the conscious derives of defensive mechanisms and (d) the relationships between these cognitive and defensive variables, in young people's cannabis intensity addiction.

Method

Forty-four young adults, 25 females and 19 males, have completed a self-reported questionnaire estimating: (a) the intensity of cannabis addiction (Décamps et al., 2008), (b) the Rusinek (2006) adaptation of Young's maladapted schemas and (c) the questionnaire of addictive beliefs of Tison and Hautekeete (1998) and the defensive styles questionnaire of Bond et al. (1983) and Bond (1995). Non-parametric statistical analysis has been conducted on three subject's groups (“non-users”, “users non addicted”, “users-addicted”) to test the implications and the links between hypothesized psychological factors (e.g., schemas, beliefs and defences) in cannabis use intensity.

Results and discussion

The intensity of cannabis addiction is correlated significantly with: (a) an hyperactivation of three maladapted schemas: inadequate autocontrol, dependence and fear of lose the control, (b) a hyperactivation of permissive, anticipatory and relief oriented beliefs and (c) a higher activation of the defence “sublimation” and a lower activation of the “displacement”. “sublimation” is correlated with the global activation of 13 schemas that are correlated with the positive relief-oriented beliefs, which are correlated with the “displacement” defence, which is correlated with the anticipatory beliefs. The results showed that the permissive beliefs have the power to differentiate the “non-consumption”, the “consumption without addiction” and “the addiction” to cannabis. Our interpretation displays that greater attention to the dysfunctional beliefs will be required in future researches and should be essential targets in cognitive therapy of this substance use disorder.     

Le rattachement lexical de la liaison : une expérience d’amorçage chez des enfants prélecteurs

The goal of the present study is a better understanding of the mechanisms involved in child segmentation of words in liaison context, where the boundary between a word1 and a word2 is ambiguous. In a priming experiment in prereaders aged 5–6 years, we examined the nature of the lexical representations, using a picture-naming task (deux ours). Targets were preceded by lexically related or unrelated auditory primes, that share the same liaison consonant or not (trois ours, un ours, trois oublis, un oubli). The results suggest that the liaison consonant is lexically encoded at the initial of variants of the word2 (/nurs/, /zurs/ for ours). They support the usage-based model of liaison acquisition [J Child Lang 36 (2009) 557–596].     

Défis et contraintes des recherches sur les familles recomposées : l'exemple de la relation belle-mère-belle-fille

Research accomplished in this field indicates clearly that of all the members of the stepfamily, it is the stepmother that encounters the most difficulties in adapting to the stepfamily situation. Furthermore, the same research also shows that the stepmother/stepdaughter relationship appears to be the most challenging of all dyads. This analysis also enables us to identify the results that appear most significant and to propose different hypotheses for future research.     

Qualité de vie des enfants asthmatiques : impact du sentiment d’efficacité personnelle, du ressenti des enfants, et de la gestion de l’asthme par les parents

The objective of this research was to investigate the influence of children's self-efficacy, attitudes and their parent's asthma management on quality of life among children suffering from asthma. One hundred and forty-six children (8-12 years old) with moderate to severe asthma filled in a quality of life questionnaire, and a self-efficacy and attitudes scales; 92 parents completed the childhood asthma self-management scale. Results show that the children's negative feelings about asthma and the parents’ difficulties to manage asthma are linked to a worse quality of life; the children's self-efficacy influences both positively and negatively children's quality of life. The development of parents’ asthma management program should enhance their children's quality of life.     

Les effets de l’ingestion aiguë d’alcool sur le jugement d’expressions faciales émotionnelles spontanées et dynamiques

This study is interested in the link between acute alcohol consumption and the perception of dynamic and spontaneous emotional facial expressions (EFE). The noxious effects of alcohol on EFE recognition are now well demonstrated (Attwood et al., 2009a). Studies showed that alcohol drinking impairs the judgment of facial expressions, especially of negative ones (EFE of anger and disgust notably). However, such effects have been observed for the judgment of artificial material (static/posed/morphed/EFE). Yet, everyday EFE are far from the archetypes used in the lab. Therefore, the present study aims at completing previous observations, this time for the identification of dynamic and spontaneous EFE. Dynamic and spontaneous EFE of amusement, interest, irritation, anxiety, and neutral were judged by 63 normal male drinkers. Buck et al.’s (1972) paradigm was adopted since it is recommended for the study of nonverbal behavior in the process of communication ( [Buck, 1990] , [Wagner, 1990] , [Wagner et al., 1986] and [Zuckerman et al., 1976] ). The emotion to be identified is the one self-reported by the EFE sender. On the pretext of tasting drinks, participants were randomly assigned to one out of six experimental conditions. Two conditions are concerned with the nature of the drink (alcohol or non-alcohol drink). Three other conditions relate to the participant's experimentally manipulated belief regarding the nature of the drink (non-alcohol drink, slight alcohol drink, hard alcohol drink). Results confirm the emotion identification impairment due to alcohol usually noted, thus showing that the effects of alcohol are also observed for the perception of spontaneous and natural facial expressions. Indeed, the comparison of participants who drank alcoholic drinks versus those who did not drink alcohol shows that the formers identify less well emotions than the latter. Moreover, results show that beliefs do not play a role in this deficit since participants’ identification errors are not linked to the belief they hold regarding the nature of the drink (with/without alcohol). Finally, the confusion matrix analysis brings to light the existence of recurrent confusions amongst alcoholized participants, confusions that do not appear amongst sober participants. Thus, results show that, to the exception of EFE of amusement, participants who drank alcohol recurrently assess stimuli as displaying anxiety. To conclude, it comes out that acute alcohol drinking alters the capacity to accurately identify spontaneous emotions expressed by faces, which capacity is essential to the smooth unfolding of human interactions.     

Effets de l’âge et de la capacité de mémoire de travail sur l’exécution d’instructions de complexité variable chez des adultes jeunes et âgés

Technical devices are part of elderly people's daily life. Meanwhile, research has not yet systematically explored how old people understand procedural instructions accompanying these devices. Thus, the aim of this study was to investigate how age and memory span affect how people follow procedural instructions. To do so, the Reading Span Test of Daneman & Carpenter (1980) and an adaptation of the Kaplan & White's (1980) following directions game were administrated to young and older adults. The Reading Span Test was administrated in order to determine the participants’ memory span size. Then, participants had to follow procedural instructions with a growing complexity displayed on a computer screen. Results show that participants’ age and instructions complexity affect how the instructions are performed. Old adults encounter more difficulty performing the task than young adults. Furthermore, whatever the age, as the complexity of instructions increases, low-span participants have more difficulty performing instructions than high-span participants do.     

Les modes de scolarisation des enfants à haut potentiel et leurs effets

Many modes of schooling of gifted children have been tested and each one has its partisans. These various modes of schooling are presented and the studies relating to their effects are reviewed. The results show that the effects do not depend on the mode of grouping of the children but depend on the modifications introduced into the content of teaching programs or the rhythm to which they are teached (compacting, accelerating, etc.). Children being both gifted and motivated to progress more quickly seem able to complete their courses in 1 or 2 years less, without apparent disadvantage. However, there are few longitudinal studies that indicate the long-term effects of these various modes of schooling.     

Individu dangereux et situations dangereuses : les représentations sociales de la dangerosité chez les citoyens, les magistrats et les surveillants de prison

The notion of “dangerousness” takes an increasing importance currently at the level of the Justice, magistrates and supervisors of jail being brought thus to assess it frequently. A question arises then, that of the significance assigned by these professionals to dangerousness. Results of the interviews achieved close to these two groups as well as with citizens reveal homogeneous representations as for the dangerous individual but greatly heterogeneous representations with respect to the dangerous situations. While confirming the existence of several dangerousness (social, penal and prison), these results also show that all dangerousness assessment can be satisfactory on condition that it is done in an both clinical and social approach.     

Le développement de la mémoire de travail : perspectives dans le cadre du modèle de partage temporel des ressources

Working memory has a central role in cognitive development and its capacity is among the best predictors of high-level cognition and school achievement. Within the Time-Based Resource Sharing (TBRS) model, three main factors account for the development of working memory capacity. In this paper, we will review the main empirical evidence sustaining the impact of two of these factors on cognitive development. First, the amount of attention available for cognitive functioning might increase during childhood. Thus, for the same activities, older children would be able to process information faster than younger children. Within working memory span tasks, because the level of activation of memory traces decreases during the processing steps, any reduction of the duration of these steps directly diminishes the time during which the traces decay, and consequently increases the time available for reactivation or refreshing before the next processing step. These two effects jointly induce a stronger activation of the memory traces and a better recall of the to-be-maintained items. Second, because the main hypothesis of the TBRS model is that attention switches to refresh memory traces from processing to maintenance during the processing episodes, the efficiency of the refreshing mechanism should have a direct and strong impact on working memory functioning. An increase in the efficiency of this refreshing during childhood means that older children should take a greater advantage from the short pauses left free between each processing step. The level of activation of the memory traces would be then higher for older than for younger children, resulting in the classically observed increase in span. As a consequence, age-related changes in the efficiency of the refreshing could play a central role in working memory development.     

Étude des stratégies d’adultes présentant un retard mental dans la résolution de la Twenty Questions Task

A Twenty Questions problem solving Task was given to 30 mentally retarded adults, 30 mentally nonretarded adults matched on chronological age, and 12 mentally nonretarded children matched on cognitive efficiency. Four strategies were identified on the basis of a subject-by-subject analysis. Results showed group differences of frequency in the use of the strategies. Moreover, results indicated that the more frequent strategy used by the mentally retarded adults is the one which consists in identifying the categories without using them to efficiently reduce the problem space. The interpretation of the results as reflecting a conceptual deficit or a chronicle cognitive sub-functioning of the mentally retarded adults depicted in the literature is discussed.     

Approche dynamique et temporalité en psychologie sociale

The purpose was to specify the advantages and limits of the dynamical perspective proposed by Nowak et Vallacher (1998) for social psychology studies. This perspective contributes massively to new knowledge in economy, biology and motor control. Theoretical models, methods, self-assessment tools, and time series analyses are now available for addressing hypotheses that nomothetical approach has let unanswered, and to determine the impact of daily events on self-perception.     

Communication engageante et représentations sociales : une application en faveur de la protection de l’environnement et du recyclage

The aim of this study is to compare the effectiveness of several communication strategies, by articulating the binding communication paradigm and the social representation theory, in order to encourage young sportsmen to act for environmental protection. A pilot study made it possible to identify central and peripheral elements of the social representation of environmental protection. An experiment was conducted and the results conform to our expectations. On one hand, the participants in the binding communication situation express attitudes and behavioral intentions more favorable towards recycling and environmental protection than those who only read the persuasive message. On the other hand, the activation of central elements involves more important changes in attitudes and behavioral intentions than the activation of peripheral elements.     

Développement des capacités sociolinguistiques chez des enfants et adolescents porteurs de trisomie 21 et étude de l'environnement sociolinguistique maternel

The aim of our research is to understand the language disturbances in Down syndrome children. Several studies demonstrated substantial differences between sociolanguage behaviours of mothers' Down syndrome children and those of mothers of non retarded children. We propose that these differences can explain DS language disturbances. So, we have compared 12 mother-child dyads (4 Down syndrome children are from 8 to 9 years, 4 are from 12 to 13 years and 4 are from 16 to 17 years). Dyads play in tutorial interaction. Results show language abilities evolution for Down syndrome subjects. Nevertheless, mothers' sociolanguage behaviors do no change.     

Étude des préférences affectives dans la relation fraternelle au travers du dessin de famille imaginaire

This article reveals the role of older (real or imaginary) brothers and sisters, and more broadly the part of affective process in socialization of 4-5 years old girls born of mixed sibling, single-sex sibling or single girl. We used the imaginary family drawing followed by an interview on the sibling relationship. The qualitative and quantitative analysis' results reveal that identifications are always overloaded to the affects but are directed according to the sex of the chosen model. Moreover, most of the girls increase their own sex-group and assert in this manner their sexual identity. The brother's experiment depends on the populations and allows the child in a mix-sibling configuration to be more flexible according to sexual stereotypes.     

Motivation et métacognition : les buts de compétence prédisent les processus métacognitifs en résolution de problèmes mathématiques

This study analyzes the effects of achievement goals on the metacognitive processes as 200 students solve two mathematical problems differing in complexity. Results show that the diverse achievement goals have significant effects both on metacognitive experiences and on metacognitive strategies, coherently across the two problems. Mastery-approach goals predict the feeling of liking the task, mastery-avoidance goals have an effect on the use of metacognitive strategies, whereas neither performance-approach nor performance-avoidance goals are significantly related to metacognitive processes. The results offer a rich picture of the interactions between goals and metacognitive processes, revealing the major role of mastery-avoidance goals.
