Representational development of the human figure in familial retardates.

Representational development of the human figure of normal and familially retarded children was examined. Five tasks were employed: Drawing a Person, Figure Completion, two Form Puzzles, and Drawing on Dictation. Ss included 34 normal children, ages 3-0 to 5-10, and 34 familially retarded children, ages 4-4 to 13-1. The two groups were matched for mental age, socioeconomic status, public school attendance, and intact family structure. Results indicate that familial retardates performed as well as normals and at times surpassed them. Performance on these representational tasks is, predominantly, a function of mental age which lends support to a "developmental" theory of familial retardation and refutes the "defect" hypothesis.     

The Frequency and Intensity of Negative Attitudes Expressed in Play Therapy: A Comparison of Well-Adjusted and Disturbed Young Children

The relationship of age and IQ to response inhibition in children was investigated in two experiments. Two tasks were employed: a “walk slowly” task designed to measure motor inhibition and a simple matching task designed to measure cognitive inhibition. In Experiment I, the Ss were 20 “normal” children at ages 4, 5, 6, and 7 years of age. Response inhibition was found to increase with age. In Experiment II, the Ss were 48 institutionalized retardates, half between the ages of 8 to 12 and half between the ages of 13 to 17. Half of each age group had IQs between 40 and 55, and half had IQs between 56 and 70. Motor response inhibition varied as a function of age but not IQ, while cognitive inhibition varied as a function of IQ but not age.     

Emergence of representation in drawing: The relation between kinematic and referential aspects

To identify and characterize early instances in which children attribute meaning to their drawings, scribbles of 2- to 3-year-olds were examined from kinematic and representational perspectives. Scribbles were shown to be composed of smooth-inertial and angular-intentional curves, the former revealing a systematic relation between curvature and speed (the 2/ 3 power law). Children tended to attribute a-posteriori representational meanings (e.g., an airplane) to angular curves and nonrepresentational meanings (e.g., a line) to smooth curves, that they have just finished drawing. They did not do so with reference to scribbles drawn by peers, by themselves in the past, or by the experimenter who imitated their scribbling. Children's attribution of representational meanings increased with age. The phenomenon studied was discussed as a possible precursor of preplanned representational drawing, indicating the child's awareness of the symbolic function of a line—standing for itself and signifying a referent.     

A Study of Seventh Grade Children's Reading of Comic Books as Related to Certain other Variables

Developmental changes in a variety of cognitive processes as a function of age and schooling were examined in 160 rural Guatemalan children aged 5, 7, 9, and 11 years. Larger differences in test performance were seen between ages 9 and 11 than during earlier age periods on most tasks. Regression analyses of years of schooling controlling for age, sex, and socioeconomic status indicated that the effects of school were limited to memory tasks and to response time on the Matching Familiar Figures Test (MFF). Evidence for cumulative effects of additional years in school on test performance was weak. Good school performance was also most related to two memory measures. Previous studies indicating that schooling has a substantial effect on abstract cognitive processes were questioned; the suggestion that school performance is related to various memory processes was raised.     

Developmental Changes in Early Comprehension and Production of Drawings: Evidence From Two Socioeconomic Backgrounds

Two studies examined young children's comprehension and production of representational drawings across and within 2 socioeconomic strata (SES). Participants were 130 middle-SES (MSES) and low-SES (LSES) Argentine children, from 30 to 60 months old, given a task with 2 phases, production and comprehension. The production phase assessed free drawing and drawings from simple 3-dimensional objects (model drawing); the comprehension phase assessed children's understanding of an adult's line drawings of the objects. MSES children solved the comprehension phase of the task within the studied age range; representational production emerged first in model drawing (42 months) and later in free drawing (48 months). The same developmental pathway was observed in LSES children but with a clear asynchrony in the age of onset of comprehension and production: Children understood the symbolic nature of drawings at 42 months old and the first representational drawings were found at 60 months old. These results provide empirical evidence that support the crucial influence of social experiences by organizing and constraining graphic development.     

The role of inhibitory control in the development of human figure drawing in young children

We investigated the role of inhibitory control in young children’s human figure drawing. We used the Bear–Dragon task as a measure of inhibitory control and used the classification system devised by Cox and Parkin to measure the development of human figure drawing. We tested 50 children aged between 40 and 64 months. Regression analysis showed that inhibitory control predicted development in human figure drawing even after the effect of age was excluded. These data suggest that inhibitory control plays a role in the development of children’s drawing and imply a relation between the executive functions and representational change.     

Young Children's Knowledge of the Representational Function of Pictorial Symbols: Development Across the Preschool Years in Three Cultures

Three- to 5-year-old children's knowledge that pictures have a representational function for others was investigated using a pictorial false-belief task. In Study 1, children passed the task at around 4 years old, and performance was correlated with standard false-belief and pictorial symbol tasks. In Study 2, the performance of children from two cultural settings who had very little exposure to pictures during the first 3 years (Peru, India) was contrasted with that of children from Canada. Performance was better in the Canadian than Peruvian and Indian samples on the picture false-belief task and drawing tasks but not on the standard false-belief measure. In all settings, children passed drawing and standard false-belief tasks either concurrently with, or prior to, passing the picture false-belief task. The findings suggest that children's explicit knowledge of the representational function of pictorial symbols matures in the late preschool years and develops more rapidly in cultures that strongly promote the symbolic use of pictures early in life.     

A teacher‐centered exploration of the relevance of social factors to theory of mind development

Many accounts of children's Theory of Mind (ToM) development favor a cognitive explanation, for example, in terms of mental representational improvements at or before 4 years. Here, we investigated whether social factors as rated by a child's teacher, are related to ToM development. We tested 82 children of 3–6 years on each of four ToM tasks, and their class teacher completed a social questionnaire about each child's playing behavior, sharing, talkativeness, confidence, aggressiveness and outgoingness. A measure of task memory and the child's gender were also recorded. Here, children generally passed ToM tasks after 5 years‐old, but no one gender performed reliably better than the other. Teacher‐rated confidence and playing behavior were correlated to ToM. But in a regression analysis, these were replaced by teacher‐rated talkativeness; with age and memory given primacy in both sets of analyses. It is concluded that maturation and cognitive factors may well have primacy but social factors, facilitated during early primary education, must also be given a role in ToM development.     

Cognitive function in older adults according to current socioeconomic status

Cognitive function may be influenced by education, socioeconomic status, sex, and health status. Furthermore, aging interacts with these factors to influence cognition and dementia risk in late life. Factors that may increase or decrease successful cognitive aging are of critical importance, particularly if they are modifiable. The purpose of this study was to determine if economic status in late life is associated with cognition independent of socioeconomic status in early life. Cross-sectional demographic, socioeconomic, and cognitive function data were obtained in 2592 older adults (average age 71.6 years) from the Center for Disease Control’s National Health and Nutrition Examination Survey (NHANES) and analyzed with linear regression modeling. Cognitive function, as measured with a test of processing speed, was significantly associated with poverty index scores after adjusting for educational attainment as an estimate of childhood socioeconomic status, ethnic background, age, health status, and sex (P < 0.001). Our findings suggest that current economic status is independently associated with cognitive function in adults over age 60 years.     

The Emotional Maturity of Pre- and Post-Menarcheal Girls

The aim of this investigation was to test the hypothesis that early developing adolescent girls have a less favorable attitude towards school than late developers. The Ss were 104 grammar school girls of mean age 14 years 1 month. All Ss were given Fitt's test of attitude towards school. Twenty-two pairs of early and late developers, matched for chronological age, IQ, and social class, were compared with regard to their mean attitude score and their responses to individual items of the attitude scale. The early developers were found to have a significantly less favorable mean attitude score. There was also a tendency for more early developers to endorse unfavorable items and for more late developers to endorse favorable items.     

Sex-Role Differentiation in Preschoolers: Effects of Maternal Employment

The purpose of the present study was to determine whether maternal employment affects sex-role differentiation in preschoolers, and whether this relationship varies as a function of the sex of the child, father's presence or absence, and/or the sex of the child's siblings (N = 398 boys and girls, mean age 51.2 months). The dependent measure consisted of a maximally reliable composite z score derived from five tests (Draw-A-Person, Occupational Preference, Nadleman Recall, Toy Preference, It Scale for Children). The fact of the mother working and the social status of her occupation were unrelated to sex-role differentiation, regardless of whether the child was a girl or a boy; had brothers, sisters, both, or was an only child; or came from an intact or nonintact family. However, the main effect for sex and the sex of child × sex of sibling interaction were significant.     

A Developmental Comparison of Social Class and Verbal Ability Influences on Piagetian Tasks

Summary

The present investigation attempted to evaluate the respective influences of socioeconomic status and verbal ability levels, as determinants of performance on Piagetian concrete operations tasks. A sample of 160 subjects (kindergarten to fourth grade) were matched on socioeconomic status and verbal ability levels. A battery of Piagetian tasks was administered, including a relational terms pretest, provoked and unprovoked numerical correspondence, unidimensional seriation, height and width, multiple seriation, and conservation of surface area. Results of factorial (grade level × sodoeconomic status × verbal ability × sex) analyses of variance indicated (a) an absence of significant socioeconomic status effects for any of the Piagetian tasks, (6) a significant main effect for the verbal ability and age-grade level factors on the majority of tasks excluding unidimensional height seriation, (c) a general absence of sex main effects or higher order interactions. The lack of difference with regard to socioeconomic-status levels indicates that the previous research which revealed notable socioeconomic-status influences may have had socioeconomic status confounded to varying degrees with differences in underlying verbal skills.     

Cognitive aspects of change in drawings: A neo‐Piagetian theoretical account

This study reconsiders a series of drawing tasks ( Goodnow, 1978 ) in which children have to modify their stereotypical drawing of the human figure to represent a person in movement. Another task, in which children have to differentiate the drawing of a kangaroo from that of a person, is also considered. According to a neo‐Piagetian model of drawing development ( Morra, 1995 ), it is hypothesized that three factors underlie children's ability to flexibly modify their drawings: (a) the amount of attentional resources (M capacity) that a child can use to activate task‐relevant figurative and operative schemes; (b) automatic activation of figurative schemes from perceptual input that can be obtained by presenting a model; and (c) activation of executive schemes that set appropriate goals and monitor performance, which can be obtained by manipulating contextual variables, such as task order. Three experiments (with a total of 645 participants in the age range from 5 to 9 years) tested successfully the theoretical predictions about the causal factors of drawing flexibility.     

Spatial Learning from Different Positions in a Room

Communication and role-taking skills were hypothesized to be positively affected by amount of preschool peer experience. Twenty Ss comprised two groups of 4-year-old boys and girls who differed in amount of preschool peer experience but were similar in age and verbal IQ. Intercorrelations among measures, as well as group differences, were assessed for two role-taking measures, a referential communication task, verbal expressive abilities, and peer-reported popularity. Cognitive egocentrism was low across tasks for both groups. Support for the role-taking construct was provided by significant correlations between tasks with IQ partialled out. Role-taking and communication skills were significantly related, although the contribution of verbal IQ to both was substantial. Significant group differences occurred in communication, but not role-taking skills. Findings are interpreted in terms of generalization of social experience to social tasks.     

How does Sam feel?: Children's labelling and drawing of basic emotions

This study compares the ability of children aged from 6 to 11 to freely produce emotional labels based on detailed scenarios (labelling task), and their ability to depict basic emotions in their human figure drawing (subsequent drawing task). This comparison assesses the relevance of the use of a human figure drawing task in order to test children's comprehension of basic emotions. Such a comparison has never been undertaken up to now, the two tasks being seen as belonging to relatively separate fields of investigation. Results indicate corresponding developmental patterns for both tasks and a clear‐cut gap between simple emotions (happiness and sadness) and complex emotions (anger, fear, and disgust) in the ability to label and to depict basic emotions. These results suggest that a drawing task can be used to assess children's understanding of basic emotions. Results are discussed according to the development of perceptual skills and the development of emotion conceptualization.     

Substitution with Interrupted Tasks of Differing Valence

The study was designed (a) to develop a form of the Home Life Scale for university men, an instrument which provides a measure of perceptions of their home life in their families of orientation; and (b) to examine the perceptions of university men in relation to selected background characteristics and to their attitudes concerning father-son relationships. No significant relationships were observed between (a) home life perceptions and (6) age, marital status, father's occupation and education, source of family income, and socioeconomic status of parents; nor were any significant relationships observed between (a) attitudes concerning father-son relationships and (b) age, marital status, father's occupation and education, source of family income, and socioeconomic status of parents. How-ever, a significant relationship (p = .05) was observed between home life perceptions and attitudes concerning father-son relationships, indicating that those Ss who hold negative perceptions concerning their families of orientation reflected the most permissive attitudes concerning father-son relationships. Such a finding suggests that men who view their own families of orientation unfavorably may wish to create in their families of procreation a warmer, less restrictive atmosphere.     

A Comparison of Laterality Indices in College and Retarded Subjects

The relation of laterality to intelligence was assessed by administration of Berman's ICD (Index of Cerebral Dominance) to 20 male and female college students and 20 retarded Ss (IQs 32–75) of comparable age and sex. The college Ss were more lateralized in hand, foot, ear, and eye, but it was primarily foot lateralization that distinguished the groups, despite the fact that hand was the most lateralized subsystem in both groups. While these results are not entirely consistent with Berman's, they are generally confirmatory of a positive relation of laterality and intelligence.     

Human Figure Drawing Indices of Sexual Maladjustment in Male Felons

Two figure drawing characteristics (the presence of nudity and drawing the opposite-sex figure first) purported to reflect sexual maladjustment were shown to be positively related to each other in a population of 1,000 male felons. Adult felons drew the male figure first significantly less frequently than did normal adults, adolescent delinquents and most other populations studied, and thus apparently have greater problems in establishing a masculine sexual identification. The presence of nudity in figure drawings is less common in the adult felon group than in the adolescent delinquent group. There was no relationship between the variables of type of criminal offense, ethnic group, age, intelligence, MMPI Mf score and sex of the first-drawn figure.     

Comparative study of verbal originality in deaf and hearing children.

Verbal originality scores were obtained from Onomatopoeia and Images, Form 1B, given to 181 deaf and 236 hearing Ss aged 10 to 19 yr. The hearing Ss scored significantly higher than the deaf Ss. Significant main effects for age were found but not for sex. The only significant interaction was found for hearing status and age. Deaf Ss became more productive as age increased, while performance of hearing Ss relative to age fluctuated.
