Recent research on individual differences in object cognition (OC) focused on determining how objects group together, and what type of processing lies behind the clusters--a single domain-general or multiple domain-specific processes. The expertise hypothesis suggests that all object categories are processed by the same mechanism that is…

The present study explores the relationship between basic auditory processing of sound rise time, frequency, duration and intensity, phonological skills (onset-rime and tone awareness, sound blending, RAN, and phonological memory) and reading disability in Chinese. A series of psychometric, literacy, phonological, auditory, and character…

Do we perceive correctly whether a 2-D object is balanced or unbalanced? What would be the cause of biased equilibrium judgments? In two psychometric studies, we varied independently the characteristics of the objects and the equilibrium states. First, we observed that observers were excessively sensitive to the eccentricity of the object top.…

This study investigated the relation between cerebral damage related to multiple sclerosis (MS) and cognitive decline as determined by two classical mental tracking tests. Cerebral damage in 15 relapsing-remitting MS patients was measured by diffusion tensor imaging (DTI). Fractional anisotropy, longitudinal and transverse diffusivity were defined…

There are a large number of studies demonstrating that visuospatial working memory (VSWM) involves different subcomponents, but there is no agreement on the identity of these dimensions. The present study attempts to combine different theoretical accounts by measuring VSWM. A battery composed of 13 tests was used to assess working memory and, in…

The cognitive characteristics involved in a relatively field-dependent or field-independent cognitive style and the personal characteristics associated with these contrasting styles have been shown to play a role in a) students' selection of electives and majors, b) vocational preferences they experience early in their academic careers, and c) the…

The purpose of this study was to investigate, both empirically and theoretically, the manner in which human Ss (might) learn to estimate relative frequencies of nine different outcomes of an uncertain event on the basis of a random sequence of event occurences. (Author)

In experiments involving 178 and 190 military recruits, spatial, quantitative, and verbal inspection time (IT) and visual search (VS) tasks and an intelligence test were administered. Results indicate that IT performance has a component related to intelligence tests and an independent component related to processing speed tests such as VS. (SLD)

An empirical investigation of the psychometric properties of Bieri's grid form of Kelly's Role Construct Repertory Test was designed. Preliminary norm tables for scores were established which would be necessary in building arguments for external validity of research results. (Author/JKS)

Object perception requires interpolation processes that connect visible regions despite spatial gaps. Some research has suggested that interpolation may be a 3-D process, but objective performance data and evidence about the conditions leading to interpolation are needed. The authors developed an objective performance paradigm for testing 3-D…

The review summarizes empirical findings and theoretical views related to the Stroop color-word phenomenon, in which naming of a color is disrupted and delayed by the presence of an "irrelevant" word denoting a color different from the color patch. It was deemed important to increase awareness of this phenomenon, since it involves basic…

A large sample of 11-year-olds were observed on a perceptual maze task. Three ability level groups were formed and compared as to overall response paths and specific binary decision configurations. Explanations for observed qualitative differences and discussion of the viability of the experimental approach adopted are presented. (Author/RD)

This annual report presents six research articles on child development. The articles and their authors are: (1) "Beyond Psychological Limits: Applying Human Development in Education" (John Kirkland); (2) "Beyond Reductionism: Directions toward Understanding Children" (Frank Self); (3) "A Psychometric Examination of the…

Although deficits in visual attention are often postulated as an important component of many declines in cognitive processing and functional outcomes in older adults, surprisingly little emphasis has been placed on evaluating psychometric instruments with which individual differences in visual attention ability can be assessed. This article…

PRELIMINARY ANALYSES WERE UNDERTAKEN TO DETERMINE THE POTENTIAL CONTRIBUTION OF MOTION PICTURE FILMS TO FACTOR ANALYTIC STUDIES OF HUMAN INTELLECT. OF PRIMARY CONCERN WERE THE OPERATIONS OF COGNITION AND MEMORY, FORMING TWO OF THE FIVE OPERATION COLUMNS OF GUILFORD'S "STRUCTURE OF INTELLECT." THE CORE REFERENCE FOR THE STUDY WAS DEFINED…
