In previous papers [Johnson, W., & Bouchard Jr., T. J. (2005a). Constructive Replication of the Visual-Perceptual-Image Rotation (VPR) Model in Thurstone's (1941) Battery of 60 Tests of Mental Ability. Intelligence, 33, 417–430.] [Johnson, W., & Bouchard Jr., T. J. (2005b). The Structure of Human Intelligence: It's Verbal, perceptual, and image rotation (VPR), not Fluid and Crystallized. Intelligence, 33, 393–416.] we have proposed the Verbal, perceptual, and image rotation (VPR) model of the structure of mental abilities. The VPR model is hierarchical, with a g factor that contributes strongly to broad verbal, perceptual, and image rotation abilities, which in turn contribute to 8 more specialized abilities. The verbal and perceptual abilities, though separable, are highly correlated, as are the perceptual and mental rotation abilities. The verbal and mental rotation abilities are much less correlated. In this study we used the twin sample in the Minnesota Study of Twins Reared Apart to estimate the genetic and environmental influences and the correlations among them at each order of the VPR model. Genetic influences accounted for 67–79% of the variance throughout the model, with the exception of the second-stratum Content Memory factor, which showed 33% genetic influence. These influences could not be attributed to assessed similarity of rearing environment. Genetic correlations closely mirrored the phenotypic correlations. Together, these findings substantiate the theory that the entire structure of mental abilities is strongly influenced by genes. 相似文献

This study investigated conditions leading to contextual control by stimulus topography over transfer of functions. Three 4-member stimulus equivalence classes, each consisting of four (A, B, C, D) topographically distinct visual stimuli, were established for 5 college students. Across classes, designated A stimuli were open-ended linear figures, B stimuli were circular, C stimuli three-sided, and D stimuli four-sided. Three different computer tasks then were trained with the B stimuli. Differential reinforcement and punishment procedures were then used to establish control over function transfer by the topography of the class members. For Task 1, function transfer, responding to C and D stimuli as subjects had to B stimuli, was reinforced. For Task 2, function transfer was reinforced for C stimuli but punished for D stimuli. For Task 3, function transfer was punished for both C and D stimuli. New equivalence classes were then established and tests for generalized contextual control were presented. All 5 subjects showed generalized contextual control of transfer of functions by stimulus topography. Implications of contextual control over function transfer in natural settings are discussed. 相似文献

Although people attempt many creative problem solutions, in general, most creative problem-solving efforts, at least real-world efforts, fail. In the present effort, we examine the reasons creative problem-solving efforts typically fail. We argue that creative problem-solving efforts fail, in part, due to the fundamental nature of the kinds of problems that call for creative thought. However, the nature of people's creative problem-solving skills and the context in which they attempt to develop and implement creative problem solutions also results in failed attempts to solve creative problems. Based on these observations, we discuss how one might seek to develop people to encourage more success in creative problem-solving efforts. 相似文献

The social behavior of same-sex pairs of nursery school children was observed during two ten-minute play sessions. One half of the pairs played alone during both sessions, and the remaining pairs played in the presence of a passive adult supervisor. Child pairs who played alone were significantly less aggressive and exhibited a moderate but nonsignificant increase in the expression of positive or prosocial behaviors. Unsupervised pairs also tended to verbalize more and engaged in significantly more cooperative play. The absence of adults may encourage children to employ more mature social strategies to achieve a successful relationship with their playmates. 相似文献

This study examined a sociocultural model of the influence of parental comments on body shape and eating concerns among males and females. Questionnaires were completed by 338 undergraduates. Participants reported levels of perceived parental comments, internalization of media ideals, appearance comparison, body dissatisfaction, drive for thinness and bulimia. Results revealed that, regardless of gender, internalization and appearance comparison only partially mediated the relationship between parental comments and the outcome variables. The final model for females explained a larger proportion of the variability in body shape and eating concerns than in males, with positive and negative parental comments directly related to body dissatisfaction and through it to eating outcomes. In males, only negative comments were directly related to body dissatisfaction. These findings highlight the role of parental influences in sociocultural models of the development of body dissatisfaction and eating concerns, and the gender-specific patterns of sociocultural influence. 相似文献

Anxious children are found to interpret ambiguous stories in a negative way. The current study attempted to examine the possible influence of parental fear and parental interpretation bias on the maintenance of such an interpretation bias. Children varying in level of anxiety (n=25) and their parents, filled in a questionnaire to measure their own fears, and gave their interpretations concerning nine ambiguous stories, relevant for childhood ‘interactional’ anxieties: social anxiety, separation anxiety, and generalized anxiety. Then, parents were asked to talk with their children about three of the stories. After the family discussion the children had to give their final interpretations. Results indicated that parents' self‐reported fear level and interpretation bias were associated with children's interpretation bias before the family discussion. However, no evidence was found for the idea that parents maintain or enhance the interpretation bias of their children. That is, irrespective of parental fear and parental interpretation bias, children interpreted the ambiguous stories as less negative after discussing them with their parents.
