The development of facial emotion recognition: The role of configural information
2007
International audience; The development of children's ability to recognize facial emotions and the role of configural information in this development were investigated. In the study, 100 5-, 7-, 9-, and 11-year-olds and 26 adults needed to recognize the emotion displayed by upright and upside-down faces. The same participants needed to recognize the emotion displayed by the top half of an upright or upside-down face that was or was not aligned with a bottom half that displayed another emotion. The results showed that the ability to recognize facial emotion develops with age, with a developmental course that depends on the emotion to be recognized. Moreover, children at all ages and adults e…
Developing motor planning over ages
2009
International audience; Few studies have explored the development of response selection processes in children in the case of object manipulation. In the current research, we studied the end-state comfort effect, the tendency to ensure a comfortable position at the end rather than at the beginning of simple object manipulation tasks. We used two versions of the unimanual bar transport task. In Experiment 1, only 10-year-olds reached the same level of sensitivity to end-state comfort as adults, and 8-year-olds were less efficient than 6-year-olds. In each age group, children’s sensitivity did not increase during a session: i.e., either clearly showed the sensitivity or showed no sensitivity a…
From algorithmic computing to direct retrieval: Evidence from number and alphabetic arithmetic in children and adults
1998
A number of theories of mental arithmetic suggest that the ability to solve simple addition and subtraction problems develops from an algorithmic strategy toward a strategy based on the direct retrieval of the result from memory. In the experiment presented here, 2nd and 12th graders were asked to solve two tasks of number and alphabet arithmetic. The subjects transformed series of 1 to 4 numbers or letters (item span) by adding or subtracting an operand varying from 1 to 4 (operation span). Although both the item and operation span were associated with major and identical effects in the case of both numbers and letters at 2nd grade, such effects were clearly observable only in the case of …
Working Memory in Children: A Time-Constrained Functioning Similar to Adults
2009
International audience; Within the Time-Based Resource-Sharing (TBRS) model, we tested a new conception of the relationships between processing and storage in which the core mechanisms of WM are time constrained. However, our previous studies were restricted to adults. The present study aimed at demonstrating that these mechanisms are present and functional before adulthood. For this purpose, we investigated the effect on maintenance of the duration of the attentional capture induced by processing. In two experiments using computer-paced WM span tasks, 10- year-old children were asked to maintain letters while performing spatial location judgments. The duration of this processing was manipu…
An Alternative Paradigm to Evaluate the Acquisition of the van Hiele Levels
1991
This article presents an alternative way of analyzing the van Hiele level of students’ geometrical reasoning. We evaluate the students’ answers, taking into account the van Hiele level they reflect and their mathematical accuracy. This gives us a description of how accomplished the students are in applying the procedures associated with each of the van Hiele levels and allows us to determine the students’ degree of acquisition of the van Hiele levels. In this way we obtain a clearer picture of the students’ geometrical reasoning than with the traditional assignment of one van Hiele level to the learners. An example of the application of this method is provided: We describe a test that evalu…
Divu valodu salīdzinošā analīze bilingvāli runājošiem: franču un nūfu valodā
2022
Šis darbs sniedz atbildi uz problēmjautājumiem, kas rodas bilingvālajās kopienās visā pasaulē, lai parādītu valodu prakses ietekmi uz runātāja ikdienas dzīvi. Daudzvalodu valstīs, piemēram, Kamerūnā, kur valodu skaits sasniedz 250, bilingvāli runājošie, šajā gadījumā franču-nu'fī valodā runājošie, izjūt savas valodas lietošanas pozitīvu vai negatīvu ietekmi. Minētajā kontekstā bilingvālo prasmju lietošana nepaliek bez ietekmes uz runātāju. Viņi var izjust pozitīvu vai negatīvu kognitīvo ietekmi atkarībā no apgūtajām prasmēm. Ja kompetences līmenis ir ļoti zems, kognitīvai ietekmei ir apvērsuma efekts, ja kompetences līmenis abās valodās ir pietiekošs vai līdzvērtīgs, runātājs izjūt pozitīvu…
Maternal cell phone use during pregnancy and child cognition at age 5 years in 3 birth cohorts
2018
Background: There have been few studies of children's cognitive development in relation to mothers' cell phone use, and most were limited to outcomes at age 3 years or younger. We examined the relationship between maternal cell phone use during pregnancy and cognitive performance in 5-year old children. Methods: This study included data from 3 birth cohorts: the Danish National Birth Cohort (DNBC) (n = 1209), Spanish Environment and Childhood Project (INMA) (n = 1383), and Korean Mothers and Children's Environment Health Study (MOCEH) (n = 497). All cohorts collected information about maternal cell phone use during pregnancy and cognitive performance in children at age 5. We performed linea…
Graphic syntax and representational development
2008
International audience; This chapter focuses specifically on the relationships between syntax and cognitive development, particularly representational development. Vinter, Picard and Fernandes promote the take-home message that changes in drawing behaviour during development result from changes in the size of the cognitive units or mental representations used to plan behaviour, and in the capacity to manage part-whole relationships. This hypothesis is first illustrated by reviewing studies in which children's adherence to the graphic rules when they copy elementary or complex figures is assessed. The authors also examine children's syntactical behaviour at a more global level, characterizin…
Transformations Toward Mature Thinking: Challenges for Education and Learning
2012
In this chapter, adult cognitive development and its transformation are explored in the context of a rapidly changing postmodern world. This chapter presents and describes three models of adult cognitive development and their educational implications. The models presented are Basseches’ model of dialectical thinking, Kuhn’s model of epistemological development, and Baxter Magolda’s model of the development of self-authorship. These models are described in greater detail because they present advanced forms of adult cognitive development but also because of the challenge they pose to educational practices. These models open possibilities for understanding educational practices and learning es…
