Cognitive impairment in preschoolers: Identification using the personality inventory for children-revised

This study evaluated the clinical validity of the Intellectual Screening, Development, and Achievement scales of the Personality Inventory for Children-Revised (PIC-R), as well as the newly derived PIC-R Factor IV scale, in identifying cognitive impairment in a clinic-referred sample of preschoolers. The clinical validity of these PIC-R subscales was also compared to that of the Minnesota Child Development Inventory (MCDI). The results showed that the PIC-R scales and Factor IV were reasonably successful in identifying cognitively impaired preschoolers, but much less successful in identifying cognitively normal preschoolers. Overall, the MCDI was the most successful in correctly identifying the preschoolers' cognitive status.     

Distinguishing Context Effects From Context Errors in Judgments of Behavior1

Context effects (assimilation and contrast) are examined in relation to accuracy in judgments of stimuli. Context effects are distinguished from context errors. This is shown to depend on one's definition of true scores, rater tendencies (leniency-severity) relative to true scores, and the direction and magnitude of observed context effects. The framework is illustrated empirically in a study of contrast effects involving performance judgments. Implications for reliability, validity, and agreement of behavior judgments in practice are explored.

An examination of how one's attitudes toward women are reflected in one's defensiveness and self-esteem

The Berger Self-Esteem Measure, the Marlowe-Crowne Social Desirability Scale, and Spence's (1972) Attitudes Toward Women Scale (AWS) were used to test 96 undergraduates. Subjects were divided according to sex and median split scores on the personality measures. Analysis of variance revealed a significant main effect for sex and defensiveness and approached significance for the sex × self-esteem effect (p<.10). Males and females were found to respond significantly differently on the AWS scale. Highly defensive males were more discriminating toward women and self-concept appeared to be an influential variable. However, self-esteem alone did not seem to have any significant effects.     

Configural face processing develops more slowly than featural face processing

Expertise in face processing takes many years to develop. To determine the contribution of different face-processing skills to this slow development, we altered a single face so as to create sets of faces designed to measure featural, configural, and contour processing. Within each set, faces differed only in the shape of the eyes and mouth (featural set), only in the spacing of the eyes and mouth (spacing set), or only in the shape of the external contour (contour set). We presented adults, and children aged 6, 8, and 10 years, with pairs of upright and inverted faces and instructed them to indicate whether the two faces were the same or different. Adults showed a larger inversion effect for the spacing set than for the featural and external contour sets, confirming that the spacing set taps configural processing. On the spacing set, all groups of children made more errors than adults. In contrast, on the external contour and featural sets, children at all ages were almost as accurate as adults, with no significant difference beginning at age 6 on the external contour set and beginning at age 10 on the featural set. Overall, the results indicate that adult expertise in configural processing is especially slow to develop.     

Missing sights: consequences for visual cognitive development

The effects of early-onset blindness on the development of the visual system have been explained traditionally by the stabilization of transient connections through Hebbian competition. Although many of the findings from congenital cataract and congenital blindness are consistent with that view, there is inconsistent evidence from studies of visual cognition in children treated for visual deprivation from cataract, case reports of recovery of vision in adults, and studies of visual reorganization after late-onset blindness. Collectively, the data from congenital cataract and congenital blindness indicate that early visual experience sets up the infrastructure for later learning involving both the dorsal ("where") and ventral ("what") streams. Nevertheless, there is surprising residual plasticity in adulthood that can be revealed if vision is lost either temporarily or permanently. This has important implications for understanding the role of early visual experience in shaping visual cognitive development.     

Do small white balls squeak? Pitch-object correspondences in young children

Adults with auditory-visual synesthesia agree that higher pitched sounds induce smaller, brighter visual percepts. We have hypothesized that these correspondences are remnants of cross-modal neural connections that are present at birth and that influence the development of perception and language even in adults and children without synesthesia. In this study, we explored these correspondences in preschoolers (30-36 months; n=12 per experiment). The children were asked to indicate which of two bouncing balls was making a centrally located sound. The balls varied in size and/or surface darkness; the sound varied in pitch. The children reliably matched the higher pitched sound to a smaller and lighter (white) ball (Experiment 1), to a lighter (white) ball (Experiment 2), and in one of two groups, to a smaller ball (Experiment 3). Children’s matching of pitch and size cannot be attributed to intensity matching or to learning. These data support the hypothesis that some cross-modal correspondences may be remnants of the neural mechanisms underlying neonatal perception.     

Why 8-year-olds cannot tell the difference between Steve Martin and Paul Newman: factors contributing to the slow development of sensitivity to the spacing of facial features

Children are nearly as sensitive as adults to some cues to facial identity (e.g., differences in the shape of internal features and the external contour), but children are much less sensitive to small differences in the spacing of facial features. To identify factors that contribute to this pattern, we compared 8-year-olds' sensitivity to spacing cues with that of adults under a variety of conditions. In the first two experiments, participants made same/different judgments about faces differing only in the spacing of facial features, with the variations being kept within natural limits. To measure the effect of attention, we reduced the salience of featural information by blurring faces and occluding features (Experiment 1). To measure the role of encoding speed and memory limitations, we presented pairs of faces simultaneously and for an unlimited time (Experiment 2). To determine whether participants' sensitivity would increase when spacing distortions were so extreme as to make the faces grotesque, we manipulated the spacing of features beyond normal limits and asked participants to rate each face on a "bizarreness" scale (Experiment 3). The results from the three experiments indicate that low salience, poor encoding efficiency, and limited memory can partially account for 8-year-olds' poor performance on face processing tasks that require sensitivity to the spacing of features, a kind of configural processing that underlies adults' expertise. However, even when the task is modified to compensate for these problems, children remain less sensitive than adults to the spacing of features.     

Predicting infant maltreatment in low-income families: the interactive effects of maternal attributions and child status at birth

Maternal attributions and child neonatal status at birth were assessed as predictors of infant maltreatment (harsh parenting and safety neglect). The population included low-income, low-education families who were primarily Hispanic. Child maltreatment during the 1st year of life (N = 73) was predicted by neonatal status (low Apgar scores, preterm status), as moderated by mothers' attributions. The highest levels of maltreatment were shown within dyads that included a mother with low perceived power and an at-risk infant. Partial support was found for maternal depressive symptoms as mediators of harsh parenting among at-risk infants. It is suggested that lack of perceived parental power constrains investment in protective relationships and fosters sensitization to potential threat.
