Visual attention at three months as a predictor of cognitive functioning at two years of age

The purpose of the present study was to examine the predictive power of various cognitive skills at 3 months of age in terms of later cognitive functioning. Habituating to redundant and recovering to novel stimuli at 3 months of age were found to predict later intellectual functioning at 24 months better than 3-month global intelligence or object permanence scores. In terms of information processing skills, recovery predicted later intelligence test scores better than habituation. It is suggested that changes in cognitive functioning may be viewed as a transformation of skills from one age to another rather than as a continuum of the same skills. With regard to the cognitive abilities of the 3-month-old, it is suggested that information processing may be central to cognitive functioning at this age.     

IQ and social class

A brief overview is given of the nature-nurture debate elicited on the basis of Arthur Jensen's article concerning group differences in IQ test results published in 1969.Sandra Scarr-Salapatek found that the contribution of genetic variance in IQ test results tended to be larger in a more stimulating environment and proportionately smaller in a disadvantaged environment. This finding has been tested on data from a Swedish twin study. A comparison of within-pair similarity for MZ and DZ twins with varying social background has been made. Genetic variance seems to account for a greater proportion of the variance in IQ test scores in social group I and II compared to social group III. This is in accordance with the conclusions drawn by Scarr-Salapatek and thus tend to support the above-mentioned hypothesis. It therefore seems as though the potentially restricting effects of working class conditions for the development of the kind of abilities measured by conventional IQ tests would tend to reduce the degree to which genetic differences are expressed. More stimulating environmental opportunities, on the other hand, tend to allow a greater range of such differences in the middle and higher social classes.     

Modality-specific information processing and intellectual ability

Two groups of children, one of below average intelligence and one of above average intelligence, were adminitered nine tasks involving matching information between auditory and visual modalities and temporal and spatial presentations. The below average intelligence children made more matching errors than the above average intelligence group, with no indication that matching problems were particular to one modality or particular to cross-modal as opposed to intramodal matching. Factor analyses did suggest, however, that matching processes varied according to levels of intelligence. The results are discussed in terms of the differences between modality-specific and nonmodal theoretical views of sensory systems, and it is noted that neither view alone is adequate to account for the variations found for the two intelligence groups. It is suggested that the results are consistent with Luria's research on neurological organization.     

Training school psychologists in neuropsychological assessment: Current practices and trends

Directors of school psychology programs at the Master's, sixth-year and doctoral levels were surveyed as to their program's degree of emphasis in neuropsychological screening and assessment. Despite variability according to program level, directors identified a need for training in these areas. This was particularly evident at the doctoral level, where greater flexibility exists in designing a student's program of studies. The results of this survey support the notion that training in neuropsychological screening and assessment techniques is appropriate in the preparation of specialists in the area of school psychology.     

Should “multiple imputations” be treated as “multiple indicators”?

Rubin's multiple imputation approach to missing data creates synthetic data sets, in which each missing variable is replaced by a draw from its predictive distribution, conditional on the observed data. By construction, analyses of such filled-in data sets as if the imputations were true values have the correct expectations for population parameters. In a recent paper, Mislevy showed how this approach can be applied to estimate the distributions of latent variables from complex samples. Multiple imputations for a latent variable bear a surface similarity to classical multiple indicators of a latent variable, as might be addressed in structural equation modelling or hierarchical modelling of successive stages of random sampling. This note demonstrates with a simple example why analyzing multiple imputations as if they were multiple indicators does not generally yield correct results; they must instead be analyzed by means concordant with their construction.I am grateful to Frank Jenkins, John Mazzeo, Kentaro Yamamoto, and Rebecca Zwick for comments on earlier versions of this paper.     

Racial and ethnic differences in motivation for educational achievement in the United States

Data from the National Educational Longitudinal Study [National Educational Longitudinal Study, (1994). National Educational Longitudinal Study: second follow-up (Report No.94-374). Washington, DC: U.S. Department of Education] show that on standardised scores in mathematics, reading and science, the highest mean scores are obtained by Asians and whites and lower scores are obtained by Hispanics and blacks. The same differences are present for the number of hours per week devoted to homework. It is suggested that motivational differences expressed in the amount of homework undertaken contribute to the group differences in educational achievement. Statistically significant correlations between the amount of homework and educational achievement support this hypothesis. There are also group differences in intelligence parallel to those in educational achievement, suggesting both intelligence and motivation are involved in racial and ethnic differences in educational achievement.     

The development of optimism and perceived attainment from elementary school to junior high school

Optimism (a perception of future improvement of children's own achievement levels) and perceived present attainment were examined developmentally in relation to academic achievement and motivation. Subjects were 507 Japanese third-, fifth-, and seventh-grade children. After categorization as high or low on perceived attainment (H/L) and optimism (h/l), two (Hh, Ll), three (Hh, Lh, Ll), and four (Hh, Hl, Lh, Ll) groups were obtained in the third, fifth, and seventh grades, respectively. These groups showed characteristic features in terms of motivation- and achievement-related measures. Both optimism and perceived attainment explained the differences in scores on the measures between the two third-grade groups. In grades 5 and 7 perceived attainment was the primary factor explaining the group differences, while the optimism dimension was a secondary factor, whose influence was stronger in grade 7. The results are discussed in relation to the development of self-perceptions, as well as changes in learning environment between elementary school and junior high school.     

Effect of goal difficulty and feedback seeking on goal attainment and learning1

Abstract: This field study investigated the effect of goal difficulty and feedback seeking on goal attainment and learning in Management by Objectives (MBO) programs. Participants (n = 105) described the degree of their goal difficulty. After 6 months, they answered a questionnaire that inquired about the frequency of the feedback‐seeking and the degree of learning during the 6‐month period. Data about the extent of goal attainment were obtained from the participants’ immediate supervisors. The results indicated that goal difficulty and the frequency of feedback seeking were positively related to the degree of goal attainment and learning.     

Vocabulary teaching strategies and conceptual representations of words in L2 in children: Evidence with novice learners

A controversial issue in bilingual research is whether in the early stages of L2 learning, access to the conceptual system involves mediation of L1 lexical representations [Kroll, J. F., & Stewart, E. (1994). Category interference in translation and picture naming: Evidence for asymmetric connections between bilingual memory representations. Journal of Memory and Language, 33, 149-174] or a direct route from the L2 word [Altarriba, J., & Mathis, K. M. (1997). Conceptual and lexical development in second language acquisition. Journal of Memory and Language, 36, 550-568; Finkbeiner, M., & Nicol, J. (2003). Semantic category effects in second language word learning. Applied Psycholinguistics, 24, 369-383]. The main goal of this paper is to study, in a child population, whether the creation of conceptual representations for L2 words is possible, even after only one session of learning of the L2 vocabulary. Furthermore, we do so by examining the efficacy of two different L2 learning methods: L2-L1 association learning vs. L2-picture association learning. A translation recognition task was employed to test whether there was a difference between a semantically related pair and an unrelated pair across conditions (i.e., a semantic interference effect). Results showed a significant semantic interference effect—a conceptual effect—in children after just one vocabulary learning session. Importantly, the L2-picture method produced a greater semantic interference effect than the L2-L1 method. The implications of these findings for models of bilingual memory are examined.
