Factor structure and specific variance of the WPPSI subtests at six age levels

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) was factor analyzed at each of six age levels between 4 and 6½ years through the method of principal factors. A two-factor solution, corresponding essentially to Wechsler's a priori grouping of the subtests into a Verbal and nonverbal or Performance scale, best described the 11 WPPSI subtests at each age level. Examination of the common, specific, and error variance components of the subtests across age levels indicated adequate test specificity to allow for individual interpretation of all subtests except Information and Comprehension when the null hypothesis model of ipsative interpretation of individual tests is employed.     

Performance characteristics of retarded and normal students on pattern recognition tasks

The purpose was to compare the performance of normal and educable mentally retarded children on pattern recognition tasks. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of children to find: (a) duplicate patterns and same elements as presented in model pattern sequences; (b) opposite patterns and same elements as presented in model pattern sequences; and (c) duplicate patterns but different elements than presented in model pattern sequences. The normal and mentally retarded children were matched on mental age derived from individual and group intelligence tests. Results indicated significant differences in performance measures between groups and various pattern tasks. The data support the suppositions that: (a) mentally retarded children and normal children show the same type of progression through the hierarchical arrangement of pattern tasks; and (b) mentally retarded children show a slower progression through the hierarchy than normal children when matched on mental age. Educational implications from this study are discussed.     

A Developmental Investigation of Inattentiveness and Hyperactivity

The development of inattentiveness and hyperactivity in middle childhood was investigated using a prospective longitudinal approach. Endogenous and exogenous predictors measured in infancy and in early and middle childhood were examined independently and in combination. In early childhood, quality of caregiving more powerfully predicted distractibility, an early precursor of hyperactivity, than did early biological or temperament factors. Caregiving and contextual factors together with early distractibility significantly predicted hyperactivity in middle childhood. While environmental variables also predicted hyperactivity in later elementary years, these factors did not improve the prediction beyond the influence of hyperactivity in early elementary years. The findings support a developmental view of the origins and course of hyperactivity in childhood, that is, that the emergence and persistence of AD/HD symptoms depend on developmental history along with current circumstances.     

Visual discrimination learning of random figure problems by rhesus monkeys

In a two-choice discrimination learning paradigm, a U-shaped function was found between trials to criterion and the number of sides comprising the random figure discriminanda. These data are consistent with results from human Ss and suggest similar information processing capabilities in the two species. Changing the orientation of the stimulus figures after the discrimination had been learned only partially disrupted subsequent discrimination performance. Any single difference in selected form attributes between the two figures comprising a problem was not a good predictor of learning speed, suggesting that monkeys use a combination of such factors.     

Teacher Knowledge and the Disjunction between School Curricula and Teacher Education

As partners in school curriculum reform, teacher educators have a responsibility to graduate students who are ready to take positions as competent and confident curriculum leaders. However, some curriculum initiatives such as those associated with the introduction of key learning areas in Australia have highlighted the disjunctions between teacher education programmes and contemporary curriculum documents. This article will explore the disjunctions from two perspectives: firstly, by examining the organisation of knowledge in schools and universities, and secondly, by presenting data from a school-based evaluation of the Health and Physical Education key learning area syllabus. The article conclude by raising implications for teacher education and the future organisation of knowledge.     

Supplementation of urban home visitation with a series of group meetings for parents and infants: results of a "real-world" randomized, controlled trial

OBJECTIVE: Home visitation has been shown to be effective in reducing rates of child maltreatment and in enhancing psychosocial outcomes in children and their parents. Even when available, however, it is underutilized by parents in some urban settings. We tested a supplemental 10-session group intervention for its ability to increase active participation in home visitation, enhance the quality of caregiving behavior of parents, and improve social developmental outcome in children. METHOD: A randomized controlled design was utilized, involving two separate cohorts of parents of 3- to 18-month old infants, totaling 148 parent-child dyads. The intervention focused on practical experience in promoting parent-infant attachment relationships. RESULTS: At 6 months follow-up, there was a substantial increase in the proportion of intervention group parents participating in home visitation, compared to parents in the control group (Fisher's exact p = .008). Parents in the intervention group exhibited a trend for improvement in their capacity to appropriately interpret infants' emotional cues (p = .08), independent of the effects of home visitation itself. Attrition in both the treatment and control groups was inversely associated with income and level of education. CONCLUSIONS: Group meetings may constitute an effective means of engaging stressed urban families in home visitation.     

SES-related aspects of neuropsychological performance

Children from different socioeconomic backgrounds have been observed to employ different cognitive styles in problem-solving situations. These cognitive styles have in turn been linked to the functional specialization of the cerebral hemispheres. It was hypothesized, therefore, that performance asymmetries would also be SES-related, high-SES children processing stimuli presented to the right visual field-left hemisphere (RVF-LH) more efficiently than those presented to the left visual field-right hemisphere (LVF-RH) and low-SES children showing the reverse pattern. A laterality task was administered tachistoscopically to 120 children, divided evenly by SES (high and low), sex, and grade (fifth and seventh). A marked RVF-LH advantage emerged among the high-SES group and a weak LVF-RH advantage among the low-SES group. Thus, the results provided general support for the central hypothesis. The findings are reviewed in the context of current models of human information processing in the cerebral hemispheres, and their broader implications for understanding SES-related differences in cognitive function are discussed.     

Operant responding with free access to the reinforcer: A replication and extension

This study was conducted to assess the maintenance of operant responding in the presence of free access to the reinforcer. The results replicated earlier research using food reinforcement and demonstrated that the same general results could be obtained with water reinforcement.     

We can be as busy as a bee: a grounded theory study of Filipino elderly prisoners’ engagement

ABSTRACT

The centrality of social relationship for older adults living in prison cannot be underestimated. While previous studies have investigated the loss of social functioning among older prisoners, there is no known information pertaining to how engagement is experienced among this vulnerable group. This grounded study purports to describe the process by which engagement is experienced among a select group of incarcerated Filipino elderly. Strauss and Corbin’s Grounded Theory design was utilized. A total of 25 incarcerated Filipino elderly in the largest penitentiary in the country were purposively chosen to participate in semi-structured interviews. Field texts were subjected to thematic analysis involving open, axial, and selective coding. Finally, themes were validated via member checking procedure. Interestingly, the study afforded the development of de Guzman, Herrera, Hernando, Hipe, and Valdez Zipper of Engagement Theory among incarcerated elderly. Interestingly, three phases relative to engagement emerged, namely: Initiating, Connecting, and Enabling. Primarily, the Initiating phase involves feelings of fear and nervousness as the incarcerated elderly familiarize themselves with the prison environment. The Connecting phase typifies recognition of the benefits of engagement leading to voluntary participation in activities. Finally, in the Enabling phase, inmates empower themselves and others to grow as they fully acquire the sense of engagement. Gerontological education and research implications are discussed.
