The present study examined the posited structure of the Wechsler Intelligence Scale for Children--Fifth Edition (WISC-V) ancillary index scores with normative sample participants aged 6-16 years (N = 2200) using a series of confirmatory factor analyzes (CFA) with maximum likelihood estimation. CFA results supported the retention of auditory…

More than 50 years since the introduction of the concept of divergent production, little progress has been made in the development of parsimonious theoretical models that sufficiently explain creativity. Recently, the optimal foraging theory has been used to explain the search for items in memory tasks, suggesting the correspondence between the…

Processing fluency has been shown to have wide-ranging effects on disparate evaluative judgments, including judgments of liking and familiarity. One account of such effects is the hedonic marking hypothesis (Winkielman, Schwarz, Fazendeiro, & Reber, 2003), which posits that fluency is directly linked to affective preferences via a positive…

Little empirical data are available concerning the cognitive abilities of gifted individuals in general and especially those who excel in mathematics. We examined visual processing abilities distinguishing between general giftedness (G) and excellence in mathematics (EM). The research population consisted of 190 students from four groups of 10th-…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

An increasing number of studies has investigated the latent factor structure of executive functions. Some studies found a three-factor structure of inhibition, shifting, and updating, but others could not replicate this finding. We assumed that the task choices and scoring methods might be responsible for these contradictory findings. Therefore,…

Recent studies suggest that there appears to be a similar developmental sequence in the understanding of mental states in both internal-state language and in standard theory-of-mind tasks. These findings suggest possible developmental relations between children's ability to talk and think about the mind. Two experiments investigated the concurrent…

The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory…

Thirty-six visual and auditory tests were given to 113 fifth and sixth grade students. Second-order analysis yielded two well-defined factors representing Fluid and Crystallized Intelligence and two perceptual factors corresponding to General Visualization and General Auditory Function. Perceptual factors were not clearly separated from broad…

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain. (RC)

Twenty-six test variables for psychological differentiation and cognitive abilities were factor analyzed with a view towards replication of certain factors of perceptual and conceptual differentiation and related these factors to cognitive abilities. (Author)

Any theory of information processing must address both what is processed and how that processing takes place. Most studies investigating variables which alter physical dimension utilization have ignored the large individual differences in selective attention or cue utilization. A paradigm was developed using an individual focus on information…

Background: Very little is known about the neuropsychological correlates of adaptive functioning in people with intellectual disabilities (ID). This study examined whether specific cognitive deficits and demographic variables predicted everyday functioning in adults with ID. Method: People with ID (n = 101; ages 19-41 years; mean education = 11…

Elementary and middle school children (n=105) completed measures of reading achievement and cognitive abilities. Factor analysis produced three empirically and theoretically derived factors, auditory processing, visual processing/speed, and memory. Together the three factors combined predicted 61 to 85% of the variance associated with different…
