Sex-Typed instructions and sex-role preference in young children's task performance

Two measures of sex-role preference were administered to 32 male and 32 female preschool children. Each group of children was divided according to sex-role preference scores, assigned to a male experimenter or a female experimenter, and performed two sorting tasks after being instructed that one task was masculine and the other feminine. One analysis was based on the sex preference of subjects as measured by the IT Scale for Children and the other was based on subject assignment from Toy Preference Test scores. The hypothesis that sex-role preference would predict performance on sex-labeled tasks was partially confirmed. All subjects performed better on the female task than on the male task and more accurately on all tasks with a male experimenter than with a female experimenter.This report is based on a master's thesis submitted to the University of Guelph by the first author.

The role of spatial organization in preference for color pairs

We investigated how spatial organization influences color-pair preference asymmetries: differential preference for one color pair over another when the pairs contain the same colors in opposite spatial configurations. Schloss and Palmer (2011, Attention, Perception, & Psychophysics 73 55-571) found weak figure ground preference asymmetries for small squares centered on large squares in aesthetic ratings. Here, we found robust preference asymmetries using a more sensitive forced-choice task: participants strongly prefer pairs with yellower, lighter figures on bluer, darker grounds (experiment 1). We also investigated which spatial factors influence these preference asymmetries. Relative area of the two component regions is clearly important, and perceived 3-D area of the 2-D displays (ie after the ground is amodally completed behind the figure) is more influential than 2-D area (experiment 2). Surroundedness is not required, because yellowness blueness effects were comparable for pairs in which the figure was surrounded by the ground, and for mosaic arrangements in which the regions were adjacent and separated by a gap (experiment 3). Lightness darkness effects, however, were opposite for figure ground versus mosaic organizations: people prefer figure-ground organizations in which smaller regions are lighter, but prefer mosaic organizations in which smaller regions are darker. Physiological, phenomenological, and ecological explanations of the reported results are discussed.     

Preschool children's retention of rhyming and nonrhyming text: paraphrase and rote recitation measures

In this study, we sought to clarify the effect that rhyme has on young children's short-term retention of story narratives. Sixty-four preschool children were read rhymed or nonrhyming versions of a short story where the semantic content differed only in the arrangement of lines across test stanzas. For each type of narrative, one half of the subjects attempted rote recitation of exact stody language. The remaining subjects were asked to paraphrase semantic content. Analyses revealed that rhyme enhanced word-for-word recitation in correct sequential order, whereas nonrhyming presentations evoked initial faciliotation of semantic paraphrase. The findings are discussed in terms of transfer-appropriate and levels-of-processing memory models.     

Priming of spatial distance enhances children's creative performance

According to construal level theory, psychological distance promotes more abstract thought. Theories of creativity, in turn, suggest that abstract thought promotes creativity. Based on these lines of theorizing, we predicted that spatial distancing would enhance creative performance in elementary school children. To test this prediction, we primed spatial distance by presenting 6- to 9-year-olds with pictures of increasingly distal objects (from their own desk to the galaxy) or increasingly proximal objects (from the galaxy to their own desk) and then assessed the fluency and originality of their ideas in a creativity test. We found, consistent with the hypothesis, that after priming of spatial distance, compared with priming of spatial proximity, children were more creative, as reflected in higher scores of both fluency and originality. This result was not qualified by children's age or gender.     

Independence of hand preference and sex-linked genetic effects on spatial performance.

The paper-and-pencil spatial performance of right- and left-handed high school students was compared separately for 1236 males and 1241 females. Handedness differences in favor of right-handed subjects were found among males only. Analysis of data for a subgroup of 555 subjects indicated that handedness and sex-linked genetic effects acted independently and additively on spatial performance.     

Preschool children's control of action outcomes

Naturalistic goal‐directed behaviours require the engagement and maintenance of appropriate levels of cognitive control over relatively extended intervals of time. In two experiments, we examined preschool children's abilities to maintain top‐down control throughout the course of a sequential task. Both 3‐ and 5‐year‐olds demonstrated good abilities to access goals at the lowest level of the representational hierarchy. However, only 5‐year‐olds consistently aligned their response choices with goals at superordinate levels. These findings suggest that the ability to maintain top‐down control and adjust behavioural responses according to goals at multiple levels of abstraction undergoes a marked improvement throughout the preschool period. Results are discussed in relation to current accounts of cognitive control and the monitoring of conflict in sequential action.     

Preschool children's understanding of causal connections

Preschool-aged children's understanding of causal mechanism was assessed by showing them a simple event sequence in which two objects moved in tandem. The central question was whether children would infer the presence of a mechanism linking the two objects whose movement covaried. This was tested by assessing five responses: actions when asked to move one object, explanations for how the object moved, predictions as to whether both objects would still move without a connection, inferences about the nature and location of the connection, and surprise when the objects moved without any apparent connection. The results from 3-, 4- and 5-year-olds indicated that an understanding of mechanism is firmly established by 5 years but fragile at 3 years and only revealed by some response modes. The implications of the results concerning how to characterize and test for early competence are discussed.     

Preschool children's accumulated and sustained physical activity

39 3- to 5-year-old children wore heart-rate monitors for 12 hr. on three consecutive days to examine physical activity patterns. Parent logs supplied additional information on type and location of activity. The highest number of accumulated minutes of moderate to vigorous physical activity was recorded during the weekday (38.6 min.) and weekend (31.4 min.) afternoons, a time period when more activity occurred outdoors. Sustained activity was mostly short in duration, but many children (71%) accumulated recommended amounts of activity on the weekday, fewer (46%) on the weekend. Spearman rank correlations for weekday (r=.50, p=.004) and weekend (r=.58, p=.004) activity were significant. Considering health risk factors associated with physical inactivity, early educators must look to the essence of young children's physical activity patterns in designing programs. Large motor activity that is intense and that occurs outdoors is a good place to start.     

Aesthetic preference and lateral dominance

Aesthetic preferences for photographs with the main focal content either to the left or right of the photograph's center were examined in right- and left-handed subjects. Verbal responses or manual responses were required. In one experiment with 261 introductory psychology student-subjects, left-handers more often preferred photographs with the more important part on the left ("left-geared") than did right-handers. Exp. 2, involving 84 right-handed student subjects, showed that left-geared photographs presented on the left side were preferred more often than left-geared photographs presented on the right side, and left-geared photographs presented on the left side were more often chosen when a left-handed manual response was required. Interactions between handedness, position of the stimulus, language hemisphere, and response mode make it extremely difficult to ascertain whether the right hemisphere is really more involved in aesthetic decisions.     

Preschool children's comprehension and production of directive forms

Thirty preschool children, 10 each at the 3-,4-, and 5-year-old levels, participated in two structured tasks designed to assess both comprehension and production of a full range of directive forms. In contrast to previous reports, the results indicated no significant differences in directive comprehension or production as a function of age; children in all age groups demonstrated the ability to understand and verbally encode the intent of most types of directive forms. However, the two most implicit forms, Question Directives and Hints, were complied with significantly less frequently than the more explicit forms, and were uused less often in the production task. The present findings indicate the importance of analyzing directive forms along a continuum of explicitness rather than dichotomizing them as direct versus indirect. Finally, the results are interpreted as providing indirect support for the general notion that mastery of some implicit forms may be achieved later than the acquisition of more explicit forms.     

Preschool children's identification and understanding of mixed emotions

Children up to age 10 typically deny, on verbal tasks, that mixed emotions can occur. The experiments presented in this article explore whether partial knowledge of mixed emotions exists in the preschool years. In Experiment 1, 4-year-olds, 5-year-olds, and adults chose mixed-emotion responses (e.g., “both happy and sad”) to describe mixed-emotion faces more than pure-emotion faces. In Experiment 2, 5-year-olds, but not 4-year-olds, chose mixed-emotion faces and/or labels, to match emotionally mixed stories more than emotionally consistent stories. Thus, both 4- and 5-year-olds can identify mixed emotions, but only 5-year-olds can acknowledge their expression in appropriate situations. The results are discussed in terms of a two-step developmental sequence occurring between ages 4 and 6.     

The role of belief veracity in understanding intentions-in-action: Preschool children's performance on the transparent intentions task

It is possible to have either true or false beliefs about what one is currently doing (an ‘intention-in-action’; [Searle, J. R. (1983). Intentionality: an essay in the philosophy of mind. New York: Cambridge University Press.]). The theory-theory account of the development of ‘mentalising’ skills between 3 and 4 years of age predicts that younger children should find false intentions-in-action more difficult to report than true intentions-in-action. In contrast, an executive theory of development at 3 and 4 years of age would predict that the perceived outcome of the action at the time of questioning should determine the younger child's answer, with the truth-value of the past belief playing no role. We presented 3- and 4-year-old children with a novel drawing task—the transparent intentions task—in order to pit these two accounts against each other. The truth-value of the child's (or a puppet's) intention-in-action played no role in performance. Incorrect answers referred to the unexpected final outcome of the drawing. This result supports the executive theory.     

Preschool children's development in classic Montessori, supplemented Montessori, and conventional programs

Research on the outcomes of Montessori education is scarce and results are inconsistent. One possible reason for the inconsistency is variations in Montessori implementation fidelity. To test whether outcomes vary according to implementation fidelity, we examined preschool children enrolled in high fidelity classic Montessori programs, lower fidelity Montessori programs that supplemented the program with conventional school activities, and, for comparison, conventional programs. Children were tested at the start and end of the school year on a range of social and academic skills. Although they performed no better in the fall, children in Classic Montessori programs, as compared with children in Supplemented Montessori and Conventional programs, showed significantly greater school-year gains on outcome measures of executive function, reading, math, vocabulary, and social problem-solving, suggesting that high fidelity Montessori implementation is associated with better outcomes than lower fidelity Montessori programs or conventional programs.     

Laterality, hand preference, and human spatial ability.

6 left-handed females scored significantly below 60 right-handed females on a test of spatial visualization (p less than .005). 13 left-handed males showed a higher mean score than 33 right-handed males on the spatial test, although this difference was not statistically significant. These results are consistent with the hypothesis that the left cerebral hemisphere is of greater relative importance to spatial functioning in females than males.     

Torque,lateral preference,and cognitive ability in primary-grade children

It has been suggested that torque, the tendency to draw circles in the clockwise direction, is related to left-handedness and is a marker for psychopathology. Results of recent studies conflict with this hypothesis hut are weakened by imprecise definition and unreliable assessment of torque. Measures of torque, lateral preference, and cognitive ability were administered to 181 children in kindergarten and first grade. As reported previously, rate of torque decreased with age and was greater among males. Children with complete clockwise or counter-clockwise circling at both assessments differed in pattern but not in overall level of cognitive ability No differences were found in strength, direction, or concordance of hand and foot preference. Results of this and other studies are seen as inconsistent with proposals that torque is symptomatic of psychopathology.     

Effects of explaining on children's preference for simpler hypotheses

Research suggests that the process of explaining influences causal reasoning by prompting learners to favor hypotheses that offer “good” explanations. One feature of a good explanation is its simplicity. Here, we investigate whether prompting children to generate explanations for observed effects increases the extent to which they favor causal hypotheses that offer simpler explanations, and whether this changes over the course of development. Children aged 4, 5, and 6 years observed several outcomes that could be explained by appeal to a common cause (the simple hypothesis) or two independent causes (the complex hypothesis). We varied whether children were prompted to explain each observation or, in a control condition, to report it. Children were then asked to make additional inferences for which the competing hypotheses generated different predictions. The results revealed developmental differences in the extent to which children favored simpler hypotheses as a basis for further inference in this task: 4-year-olds did not favor the simpler hypothesis in either condition; 5-year-olds favored the simpler hypothesis only when prompted to explain; and 6-year-olds favored the simpler hypothesis whether or not they explained.
