Généralisation de propriétés biologiques, physiques et comportementales chez l’enfant de cinq à neuf ans

This study is designed to examine how biological knowledge is organized and structured in children. Five- to nine-year-old children's interpretations of biological phenomena are studied by examining to what extent the transmission of different kinds of properties is perceived as being causally related to birth origins. A property generalization task is used, in which biological relations (birth origins) are pitted against adoptive relations. The characteristics to be generalized correspond to non-obvious biological characteristics, visible physic characteristics or behavioural characteristics. Our results show that five-year-old children do not understand the origin of these characteristics. A conceptual change seems to be at work by the age of seven but the delimitation of biological categories remains imperfect.     

Structure implicative des propriétés, conséquences pour l'étude de la catégorisation

We show how the notion of implication between properties and the relevance principle shed new light on the results of Rosch and her colleagues (1975, 1976). To uncover our hypotheses, concerning relationships between properties, participants were asked to respond to propositions linking properties A and B, relative to birds, of the type “If A, can it generally be said that B?” Results show that some properties are linked one to the other (quasi-equivalence, quasi-implication, or quasi-independence) and that these implicative links can be summarized by an implicative graph. The resulting property structure has a predictive character for participant response times.     

Étude développementale de l’interprétation de combinaisons conceptuelles nominales « relation » et « propriété »

The present research addresses how people interpret novel noun-noun conceptual combinations. First, we focused on two types of conceptual combinations: property and relational combinations. Secondly, we manipulated the order of the constituents. Finally, we studied if the interpretation in terms of “Property” or “Relation” changes along with age. So, four groups of 6-, 8- and 10-year-old children and adults participated in a production task. Our results indicated that the interpretations in terms of relation were more frequent for the “Relation” combinations compared to the “Property” ones. Property-transferring interpretations increased with age when Property combinations are presented. The most frequent interpretations followed the order Head noun-Modifier, which is opposite to the order observed in English.     

L'interprétation d'indices non verbaux par les enfants

Interpreting appropriately face expressions and analyzing social relations between people, according to their actions are useful competence for treating pragmatic aspects of communication. We do research on these competences by presenting a recognition emotion task, and a task in which movements of geometrical figures simulate social interaction, to 98 children (children aged 8, 10, 12 and 14 years, children with autism and mental retardation). Results show that answers qualitatively increase with age, even after 12 years. Children with autism encounter more difficulties to recognize emotional expression than to attribute intentional actions. Emotion recognition is related to simple intention attribution but not with complex one, which develops later.     

Développement de la précision temporo-motrice et cadences spontanées de jeunes enfants

Fifty children (six to ten years old) were asked to tap a flat surface as regularly as possible with their finger at different semi-spontaneous tempi. Their chosen tapping speed was estimated by each sequence's mean inter-tap interval. The range of chosen speeds widens with age. The just tenable difference (JTD) between inter-tap intervals is proportional to their reference, the mean. The motor-timing precision, estimated through the standard-deviation/mean ratio, clearly improves with age. Children are more precise at faster tempi, not around their “normal” tempo as adults. Our simple semi-spontaneous finger-tapping task could be applied to the clinical evaluation of age-dependent explicit and implicit timing components in motor performance.     

Théories naïves et raisonnements téléologiques sur les animaux et les plantes

The cognitive status of plants as a biological category remains unclear in the conceptual organisation. A series of five experiments investigated whether adults agree with different kinds of teleological assertions to account for attributes of animals or plants. One major finding is that adults are inclined towards explanations that evoke an advantage for other species to motivate the existence of attributes in plants, but not in animals. This supports our assumption about social-serving teleological reasoning for plants, as for artefacts, and may contribute to increase the ambiguous status of plants within the unified concept of living thing. Therefore, plants may not only differ from animals by the low relevance of an intuitive psychology to account for their properties, but also by their tendency to trigger intuitive explanations devoted to artefacts.     

Developmental effects of typicality and superordinate property dominance on sentence verification

Second graders (mean age, 8 years 3 months), fourth graders (mean age, 10 years 4 months), and adults verified telegraphic sentences with typical or atypical subject nouns and high or low dominant property predicates. The hypothesis tested was that the similarity in the attribute structures of category members to their superordinate prototype should be related to degree of typicality. Adult reaction time and error data supported the prototype model of semantic category structure. Second and fourth graders showed comparable property knowledge to adults, but evidenced different organizational patterns than predicted by the adult model. The results suggest that with development children learn to simultaneously use many attribute dimensions and to abstract the family resemblance structure and relative importance of category properties.     

How do young children deal with hybrids of living and non‐living things: The case of humanoid robots

In this experiment, we tested children's intuitions about entities that bridge the contrast between living and non‐living things. Three‐ and four‐year‐olds were asked to attribute a range of properties associated with living things and machines to novel category‐defying complex artifacts (humanoid robots), a familiar living thing (a girl), and a familiar complex artifact (a camera). Results demonstrated that 4‐year‐olds tended to treat the category‐defying entities like members of the inanimate group, while 3‐year‐olds showed more variability in their responding. This finding suggests that preschoolers' ability to classify complex artifacts that cross the living–non‐living divide becomes more stable between the ages of 3 and 4 and that children at both ages draw on a range of properties when classifying such entities.     

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.     

Rythmicités de l’attention des enfants et synchronisation,perspective socioécologique

This study investigates the impact of socioecological synchronization on the level and variations in children's attention at school. The aim was to re-examine previous results and broaden the chronopsychological scope of the research to include new synchronizers originating from proximal ecological niches. Two time-management factors were considered, the organization of the school timetable and the regular and predictable daily time with parents, influenced by work organization and compromises within the family. Two studies were conducted on a total of 498 children between six and 11 years of age. Results confirm a daily attention pattern. The level of performance and the daily pattern are affected by the two time-management factors whose beneficial or adverse influence depends on the child's age. Thus, while the weekly school timetable organized over four days has the strongest negative impact on attention performance for the two age groups, desynchronization due to a longer week-end is greater in the older children. The effects of the two possible four-and-a-half-day timetables also differ according to age. The benefits of working on Wednesdays for younger children appeared less beneficial for the older pupils. Regular and predictable daily time with parents does appear to play a role which also varies according to age, as it has an effect on younger children but has no impact on older children's attention or performance. This study confirms the synchronizing role of temporal messages from school and parental niches in the level and variations in children's attention at school, and is in line with the ecological point of view demonstrated by chronobiological studies. These findings support the importance of research that takes an overall approach to the child's environment. Further work should investigate the prioritization of social synchronizers according to their proximity to the child and how they interact.     

The development of biological knowledge: A multi-national study

This study was designed to differentiate between universal and culturally specific aspects of children's biological understanding. Kindergartners, second graders, and fourth graders from Israel, Japan, and the United States were asked whether people, other animals, plants, and inanimate objects possessed each of 16 attributes. The attributes included life, unobservable attributes of animals, sensory capacities, and attributes of all living things. The results indicated that children of all three ages in all three countries knew that people, other animals, plants, and inanimate entities were different types of things, with different properties. Children in all cultures were extremely accurate regarding properties of humans, somewhat less accurate regarding properties of other animals and inanimate entities, and least accurate regarding properties of plants. As predicted from cultural analyses, Israeli children were the most likely to fail to attribute to plants qualities that are shared by all living things. Also as predicted, Japanese children were the most likely to attribute to inanimate entities attributes possessed only by living things. In contrast to many previous findings, U.S. children in the study presented here displayed more accurate scientific knowledge than age peers in Japan or Israel. The results were analyzed in terms of how cultural beliefs and linguistic categories affect knowledge acquisition processes and scientific understandings.     

Vers une prise en compte de la contrainte liée à l’effecteur dans la dynamique de coordination graphomotrice

Comparing two independent experiments following the same paradigm, the present article ponders the influence of constraints on graphic activity. A first study realized by Athènes et al. (2004) on the reproduction of simple graphic shapes revealed the presence of five preferential shapes when the effector was not constrained. With the forearm fastened, our results suggest that four only shapes are preferential when reproducing these same shapes. Overall, our findings suggest that the addition of a constraint related to the effector does not necessarily imply a negative effect on the graphic landscape. Were this assumption to be confirmed by full-fledged studies, it would be then possible to reveal new preferential shapes that are not spontaneously reproduced without additional constraints.     

Revisiting preschoolers' living things concept: a microgenetic analysis of conceptual change in basic biology

Many preschoolers know that plants and animals share basic biological properties, but this knowledge does not usually lead them to conclude that plants, like animals, are living things. To resolve this seeming paradox, we hypothesized that preschoolers largely base their judgments of life status on a biological property, capacity for teleological action, but that few preschoolers realize that plants possess this capacity. To test the hypothesis, we taught 5-year-olds one of four biological facts and examined the children's subsequent categorization of life status for numerous animals, plants, and artifacts. As predicted, a large majority of 5-year-olds who learned that both plants and animals, but not artifacts, move in goal-directed ways inferred that both plants and animals, but not artifacts, are alive. These children were considerably more likely to draw this inference than peers who learned that the same plants and animals grow or need water and almost as likely to do so as children who were explicitly told that animals and plants are living things and that artifacts are not. Results also indicated that not all biological properties are extended from familiar animals to plants; some biological properties are first attributed to plants and then extended to animals.     

Structure factorielle et qualités psychométriques de la version française de l’inventaire de comportements des adultes (Adult Behavior Checklist) d’Achenbach et Rescorla

While they often need to obtain information about their patients’ functioning from friends, relatives or spouse, French clinicians currently lack a reliable and handy other-report instrument allowing for a comprehensive review of the behavioral and emotional problems presented by an adult person. The aim of the present study is to verify the factor structure and psychometric properties of the French version of the Achenbach and Rescorla's Adult Behavior Checklist (ABCL). We collected 403 ABCL forms completed by informants, who all were third-year students in psychology. The subjects (198 women) were aged 18 to 59 years and came from families with a large variety of socioeconomic status. The confirmatory factor analyses yielded the expected eight-syndrome first order factor structure and supported the measurement models implied by the DSM-oriented scales more recently added to the ABCL. French people scored higher than American on almost all scales. Women scored higher than men on the scales measuring anxiety, and lower on those measuring attention problems and rule-breaking behavior. Middle-aged people scored lower than younger on attention problems and rule-breaking behavior. Despite some limitations, these results speak in favor of the use of the French Adult Behavior Checklist in both research and clinical practice.     

Anthropocentric by Default? Attribution of Familiar and Novel Properties to Living Things

Humans naturally and effortlessly use a set of cognitive tools to reason about biological entities and phenomena. Two such tools, essentialist thinking and teleological thinking, appear to be early developmental cognitive defaults, used extensively in childhood and under limited circumstances in adulthood, but prone to reemerge under time pressure or cognitive load. We examine the nature of another such tool: anthropocentric thinking. In four experiments, we examined patterns of property attribution to a wide range of living and non‐living objects, manipulating time pressure, response type, and property (either novel or familiar) in a total of 471 participants. Results showed no tendency toward increased similarity‐based attribution patterns indicative of anthropocentric thinking under time pressure. However, anthropocentric thinking was consistently observed for unfamiliar properties. These findings suggest that anthropocentric thinking is not a developmentally persistent cognitive default, but rather a cognitive strategy deliberately employed in situations of uncertainty.     

Beyond free will: The embodied emergence of conscious agency

Is it possible to reconcile the concept of conscious agency with the view that humans are biological creatures subject to material causality? The problem of conscious agency is complicated by the tendency to attribute autonomous powers of control to conscious processes. In this paper, we offer an embodied process model of conscious agency. We begin with the concept of embodied emergence – the idea that psychological processes are higher-order biological processes, albeit ones that exhibit emergent properties. Although consciousness, experience, and representation are emergent properties of higher-order biological organisms, the capacity for hierarchical regulation is a property of all living systems. Thus, while the capacity for consciousness transforms the process of hierarchical regulation, consciousness is not an autonomous center of control. Instead, consciousness functions as a system for coordinating novel representations of the most pressing demands placed on the organism at any given time. While it does not regulate action directly, consciousness orients and activates preconscious control systems that mediate the construction of genuinely novel action. Far from being an epiphenomenon, consciousness plays a central albeit non-autonomous role in psychological functioning.     

Étude des prédicteurs de la gêne olfactive aux abords d’un site industriel

The present research aims at defining factors linked with the level of olfactive annoyance felt by residents living near an industrial site and to estimate their importance, which could predict the annoyance. One hundred and ninety-nine residents answered a questionnaire about quality of life, various annoyances found on the place of dwelling, as well as about factory and their odors. The results underline the link between the level of annoyance, characteristics of the odors and some individual and contextual factors. Moreover, the regression analysed apply at these variables show four predictive factors in the prediction of odor annoyance which are perceived olfactive sensitivity, estimated pollution level of the industrial site, unpredictability and intensity of odors.
