Females are usually assumed to be more socially oriented and skilful than males. Here, we present evidence that sex differences are not stable over time. Copyright Barbu et al. Such discrepancies are especially marked in childhood. This statistical model was applied for each of the standardized test measures; this model was also applied to performance accuracy and to reaction time for tasks performed in the scanner. To this end, children's play behavior was observed under naturalistic conditions at nursery schools during self-selected activities and spontaneous peer-groups. Cooperative play Cop significantly increased from 4—5 years to 5—6 years, representing almost half of the children's activities at the end of the preschool period. To demonstrate generalized differences, we tested for sex differences across language tasks after accounting for differences in task, stimulus modality, age, and performance accuracy. The following parameters were used for scanning: We therefore did not exclude error trials, thus avoiding differences in statistical power for age groups that differed in accuracy. Data exclusion due to subject performance Prior to fMRI data collection, subjects were given a practice session in a MRI simulator for acclimation to the scanner environment and to ensure that the behavioral requirements of each task were understood.

Lexical trials were contrasted with fixation trials to reduce the effects of fixation and motor responses. Finally, a variety of clinical conditions with marked social deficits, such as autism, occurs more often in males than in females, and has been described as an extreme manifestation of some male-typical traits, suggesting a continuum between typical and atypical social development [22]. Similarly, correlations within a stimulus modality such as auditory used the two language judgments as fixed factors in order to eliminate effects specific to language judgments; analysis was masked by the main effects of activation for this modality across both rhyming and spelling judgments. Word pairs were treated as individual events for first-level individual analyses and modeled using a canonical hemodynamic response function. Correlation with standardized test scores demonstrated the relevance of identified sex differences in brain activation to differences in linguistic skill. One pervasive stereotype about sex-related differences is that girls and women are more socially oriented and skilful than boys and men [4] — [6]. Because a parameter estimate of the differential response to the word pairs vs. Comparisons of the percentages of social play categories within age groups pairewise t-tests: Subject indicated their judgments via keypress.

This model allowed us to examine sex effects that are not specific to a particular language task, stimulus modality, or age group after accounting for differences in performance accuracy. Received Jul 29; Accepted Dec Descriptive statistics of children's playtime allocation among social participation categories within age and sex groups. The following parameters were used for scanning: From birth to the first year, infant females show stronger social orientation responses than infant males, with a stronger interest in human faces [7] — [8] , a greater amount of eye contact [9] — [11] , and more accurate imitative abilities [12]. Solitary Sol and parallel play Par showed a similar developmental course with an abrupt decrease between 3—4 and 4—5 years. Thus, the magnitude, consistency and stability across time of between-sex differences remain questioned [5] , [6] , [18].

They were also observed more frequently interacting with adults than older children for whom this proximity became rare. The visual spelling and auditory rhyming tasks require intramodal word segmentation based upon linguistic processes, whereas the auditory spelling and visual rhyming tasks require cross-modal conversion of word forms; both intra- and cross-modal tasks have been shown to activate linguistic as well as sensory regions of the brain Bitan et al. Similarly, correlations within a stimulus modality such as auditory used the two language judgments as fixed factors in order to eliminate effects specific to language judgments; analysis was masked by the main effects of activation for this modality across both rhyming and spelling judgments. Throughout childhood and adulthood, girls and women continue to be more socially expressive and responsive than age-matched males. They are also more prone to behave prosocially [18]. Bilateral activation in the inferior frontal and superior temporal gyri and activation in the left fusiform gyrus of girls was greater than in boys. Between-sex differences appear during a limited window of development and even change direction with age. One pervasive stereotype about sex-related differences is that girls and women are more socially oriented and skilful than boys and men [4] — [6]. Copyright Barbu et al. Apparent laterality differences could potentially arise from threshold effects, differences in response variability Vikingstad et al. A better understanding of the dynamics of sex differences in typical social development should also provide insights into atypical social developments which exhibit sex differences in prevalence, such as autism. Yet the developmental dynamics of sex differences has been rarely investigated, with one notable exception, but that focused on within-sex variation rather than between-sex differences [23]. We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children. The following parameters were used for scanning: More precisely, interactions with adults Adu showed a significant decrease from 2—3 to 4—5 years, becoming rare in the two oldest age groups. Examination of mean scores by age group, however, suggests that the reading advantages for girls on these measures may have been driven by the older children see Table 1. However, there are also marked individual differences in the degree to which children are willing to participate in peer play [27]. A response was required during the 2, ms interval following the second word presentation, prompted by the appearance of a red fixation cross.

Females are usually assumed to be more socially oriented and skilful than males. Materials and methods Subjects Sixty-two children including thirty-one girls participated in this functional magnetic resonance imaging fMRI study, ranging in age from 9 years to 15 years. The timing parameters for all control tasks were the same as for the lexical tasks. On the other hand, associative play Aso increased significantly between 2—3 and 4—5 years becoming twice as much frequent in 4—5 year-olds than in 2—3 year-olds, but it decreased significantly thereafter. Such discrepancies are especially marked in childhood. Comparisons of the percentages of social play categories within age and sex groups pairewise t-tests: We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children. This article has been cited by other articles in PMC. A fixation control task was used as a baseline for all comparisons. Among available peer play scales, we adapted the seminal Parten's [32] framework which covers the social spectrum of children's participation in peer play, with non-social activities: A better understanding of the dynamics of sex differences in typical social development should also provide insights into atypical social developments which exhibit sex differences in prevalence, such as autism. Nevertheless, while boys catch up and girls move on towards more complex play, sex differences in social play patterns are reversed in favor of boys at the following ages, such as in associative play at 4—5 years and cooperative play at 5—6 years. To cover all children's social activities, we also recorded social interactions with peers when children are not playing, but are involved in sustained social exchanges mostly conversations, which are more frequent in older children [26] , and social interactions with adults, as adults were present on playgrounds. In addition, a perceptual control task 24 trials was used for examining the effect of nonlinguistic sensory processing in each modality. Comparisons of the percentages of social play categories within age groups pairewise t-tests: Sex differences were here identified in children ages 9 — 15 across two linguistic tasks for words presented in two modalities. Orthographic matches and non-matches occurred equally often, so accurate performance required attention to the orthography of both presented words. Following a cross-sectional design, children aged from 2 to 6 years old, divided into four age groups, were observed during outdoor free play at nursery school. Introduction Human sex differences are a perennially hot topic that not only grips the public interest, but that has triggered a great deal of scientific focus from biological to social sciences. Similar ANCOVA models were used to look for a correlation of activation with skill estimates derived from standardized test scores. As play provides an excellent window into children's social development, we investigated whether and how sex differences change in social play across early childhood. However, there are also marked individual differences in the degree to which children are willing to participate in peer play [27].

We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children. Some studies found no sex differences whereas others reported differences that were either congruent or not with gender stereotypes. However, despite an extensive literature, the very existence of sex differences remains a matter of discussion while some studies found no sex differences whereas others reported differences that were either congruent or not with gender stereotypes. There is some evidence in support of this view. Nevertheless, while boys catch up and girls move on towards more complex play, sex differences in social play patterns are reversed in favor of boys at the following ages, such as in associative play at 4—5 years and cooperative play at 5—6 years. Orthographic matches and non-matches occurred equally often, so accurate performance required attention to the orthography of both presented words. Thus, the magnitude, consistency and stability across time of between-sex differences remain questioned [5] , [6] , [18]. Both the amount and the quality of children's play are associated with measures of social motivation and competence, in particular with peers [28] — [30]. For example, correlations with a language judgment such as rhyming used the two stimulus modalities as fixed factors in order to eliminate effects specific to sensory processing; analysis was masked by the main effects of activation for this task across both stimulus modalities. Moreover, the differences reported are not especially large or consistent throughout childhood [6]. Sex differences were observed on some of these tests, as described in the results. Solitary Sol and parallel play Par showed a similar developmental course with an abrupt decrease between 3—4 and 4—5 years. Such discrepancies are especially marked in childhood. Behavioral tasks Two language judgment tasks were used. Yet the developmental dynamics of sex differences has been rarely investigated, with one notable exception, but that focused on within-sex variation rather than between-sex differences [23]. Females are usually assumed to be more socially oriented and skilful than males. Children's social participation profiles over the preschool period. These differences are not always evident Brickman et al. In childhood, these abilities are related to general social competence, especially in dealing with peers [17] , [19] , and to different interaction and communication styles that prefigure differences in women's and men's interpersonal goals [20] , [21]. Differences in slice-acquisition time and motion were corrected; movement during a run did not exceed 4. Performed the experiments: Table 1 Standardized scores of subjects by age and sex. The same approach was used for identifying sex differences for activation by the complex perceptual control. Comparisons of the percentages of social play categories within age and sex groups pairewise t-tests: Data acquisition Brain images were acquired from a 1. Similar ANCOVA models were used to look for a correlation of activation with skill estimates derived from standardized test scores. Finally, a variety of clinical conditions with marked social deficits, such as autism, occurs more often in males than in females, and has been described as an extreme manifestation of some male-typical traits, suggesting a continuum between typical and atypical social development [22]. Parametric analyses were carried out to identify correlation of brain activation to accuracy in either the language judgment rhyming, spelling or the stimulus modality auditory, visual.

Parametric analyses were carried out to identify correlation of brain activation to accuracy in either the language judgment rhyming, spelling or the stimulus modality auditory, visual. Thus, age groups were characterized by distinct social participation profiles Fig. Females are usually assumed to be more socially oriented and skilful than males. Although the literature provides some empirical evidence, the picture is not as simple and univocal as described. The timing parameters for all control tasks were the same as for the lexical tasks. Here, we present evidence that sex differences are not stable over time. Introduction Human sex differences are a perennially hot topic that not only grips the public interest, but that has triggered a great deal of scientific focus from biological to social sciences. In this task, a black fixation-cross appeared in the center and subjects pressed a button once it turned red; as a baseline, this task removed nonlinguistic effects of target fixation and motor response present in both auditory and visual versions of our language tasks. This mask ensured that identified group differences and correlations with accuracy were limited to areas active during language tasks. From the age of 4—5 years, children's sociality changed abruptly, notably associative play predominated at 4—5 years and cooperative play predominated at 5—6 years. We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children. Throughout childhood and adulthood, girls and women continue to be more socially expressive and responsive than age-matched males. Similar ANCOVA models were used to look for a correlation of activation with skill estimates derived from standardized test scores. Functional MRI data from 43 subjects in the auditory rhyming task 19 boys and 24 girls , 42 subjects in the auditory spelling task 17 boys and 25 girls , 54 subjects in the visual rhyming task 26 boys and 28 girls , and 48 subjects in the visual spelling task 25 boys and 23 girls were used in our analyses. For example, correlations with a language judgment such as rhyming used the two stimulus modalities as fixed factors in order to eliminate effects specific to sensory processing; analysis was masked by the main effects of activation for this task across both stimulus modalities. Some studies found no sex differences whereas others reported differences that were either congruent or not with gender stereotypes. The auditory versions of the tasks were presented four or more weeks later in order to reduce rehearsal effects. The following parameters were used for scanning: Cooperative play Cop significantly increased from 4—5 years to 5—6 years, representing almost half of the children's activities at the end of the preschool period. Ninety six word pairs were presented whose orthographic and phonological similarity was manipulated independently.

One of the many, and perhaps most striking, paradoxes of gender studies is that, despite decades of concerted efforts, the very existence of sex differences remains debated [1] — [3]. The timing parameters for all control tasks were the same as for the lexical tasks. A better understanding of the dynamics of sex differences in typical social development should also provide insights into atypical social developments which exhibit sex differences in prevalence, such as autism. For example, correlations with a language judgment such as rhyming used the two stimulus modalities as fixed factors in order to eliminate effects specific to sensory processing; analysis was masked by the main effects of activation for this task across both stimulus modalities. However, there are also marked individual differences in the degree to which children are willing to participate in peer play [27]. Moreover, the magnitude, consistency and stability across time of the differences remain an open question, especially during childhood. Behavioral tasks Two language judgment tasks were used. The following parameters were used for scanning: Task accuracy from each task was entered as a continuous covariate; reaction time was not covaried because differences related to age or sex were not specific to language tasks. Yet the developmental dynamics of sex differences has been rarely investigated, with one notable exception, but that focused on within-sex variation rather than between-sex differences [23]. Females are usually assumed to be more socially oriented and skilful than males. The nature of sex differences was further explored by examining the relationship between brain activation and performance accuracy. This mask ensured that identified group differences and correlations with accuracy were limited to areas active during language tasks. Children spent also less and less time unoccupied Uno with a significant decrease at the beginning and the end of the preschool period.

Comparisons of the percentages of social play categories within age and sex groups pairewise t-tests: Solitary Sol and parallel play Par showed a similar developmental course with an abrupt decrease between 3—4 and 4—5 years. This article has been cited by other articles in PMC. For each task, a subject performed two functional runs of 8. Performed the experiments: We found significant effects of age for all the social categories: Abstract Why females generally perform better on language tasks than males is unknown. Throughout childhood and adulthood, girls and women continue to be more socially expressive and responsive than age-matched males. Activation in the left inferior frontal and fusiform regions of girls was also correlated with linguistic accuracy irregardless of stimulus modality, whereas correlation with performance accuracy in boys depended on the modality of word presentation either in visual or auditory association cortex. We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children. This developmental perspective contributes to resolve apparent discrepancies between single-snapshot studies. To cover all children's social activities, we also recorded social interactions with peers when children are not playing, but are involved in sustained social exchanges mostly conversations, which are more frequent in older children [26] , and social interactions with adults, as adults were present on playgrounds. The subject indicated whether the second triplet matched the first. Ninety six word pairs were presented whose orthographic and phonological similarity was manipulated independently. Functional MRI data from 43 subjects in the auditory rhyming task 19 boys and 24 girls , 42 subjects in the auditory spelling task 17 boys and 25 girls , 54 subjects in the visual rhyming task 26 boys and 28 girls , and 48 subjects in the visual spelling task 25 boys and 23 girls were used in our analyses.

  1. Co-registered images were normalized to the MNI Montreal Neurological Institute average template, statistical analyses were calculated on smoothed data 10 mm isotropic Gaussian kernel , and a high pass filter removed signal drift and other low frequency artifacts. Although the literature provides some empirical evidence, the picture is not as simple and univocal as described.

  2. Sex differences in some reports may arise from group differences in age Brickman et al. In the visual modality, two visual stimuli were presented sequentially, each consisting of 3 rearranged letters that bore no resemblance to alphabetic stimuli; in the auditory modality, two triplets of pure tones were presented.

  3. We sought to identify sex differences in brain activation during language tasks that could account for observed behavioral differences already apparent in young children.
