Seventy-five general and 65 special education teachers working in the same 65 elementary schools in 12 different U.S. school districts were surveyed about their mindsets concerning the malleability of writing and intelligence as well as their practices for teaching writing. All teachers taught writing to one or more fourth-grade students receiving…

In the present study, speeded tasks with differing assumed difficulties of the trials are regarded as a special class of simple cognitive tasks. Exploratory latent growth modeling with data-driven shape of a growth curve and nonlinear structured latent curve modeling with predetermined monotonically increasing functions were used to analyze…

Implicit theories of intelligence (i.e., individuals' beliefs about the nature of intelligence, such as whether it is fixed or changeable) are important because they are related to individuals' behaviors and their beliefs in other areas (Sternberg, 2000). Implicit theories of intelligence are especially important in educational settings because…

A three-stage model for the evolution of theories of intelligence is proposed and applied to understanding the evolution of correlationally based and experimentally based theories of intelligence. In stage one, alternative conceptions compete. In subsequent stages, alternative conceptions, which combine elements of prior approaches, emerge and…

This study found that 10 adolescents with mental retardation processed stimuli varying with respect to symmetry in comparable manner to peers matched for mental age and chronological age. Results argue for the robustness of the symmetry effect across groups differing in intelligence and physically dissimilar stimulus types (checkerboard versus…

The Ravens Standard Progressive Matrices Test was administered to 48 subjects who then performed a card-sorting task under single- and competing-task conditions. Hick's Law and the Roth-Jensen procedure were used in task development. Complexity should have a more central role in speed of processing models of intelligence than ability to divide…

Discusses an alternative approach to intelligence tests as a measure of intelligence. The approach is based on three classes of performance dealing with a person's choice of an internal representation for a problem, strategies for manipulating the representation, and abilities to execute elementary information processing steps required by the…

The study of cognitive processing in high IQ and average IQ elementary grade learning disabled and non-learning disabled children found that LD students were poorer in sequential processing and planning compared to NLD students; high IQ LD students lost their IQ advantage to low IQ LDs in sequential scores.

Results indicated that retarded Ss, relative to normal Ss of all ages, responded particularly slowly to static property statements when objects were animate, and to intrinsic-action properties when objects were inanimate. (Author/DLS)

The study compared the problem solving strategies of intellectually gifted (N=133), average (N=102) and mentally retarded (N=51) children on two-dimensional integration problems. Gifted children tended to integrate dimensional information by addition, average children used lexicographic strategies, and retarded children relied on a single…

This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…

Determined if Wechsler Intelligence Scale for Children-Revised subtest patterns would differentiate the performance of emotionally disturbed and learning-disabled children. Subtests differentiated significantly between diagnostic categories. Learning-disabled children performed predictively poorer on block design, picture arrangement, and object…

United States Employment Service data on the cognitive and noncognitive aptitude requirements of different occupations were used to create an occupational classification--the Occupational Aptitude Patterns (OAP) Map. Thirteen job clusters are arrayed according to major differences in overall intellectual difficulty level and in functional focus…

Individual differences in visual recognition memory and intelligence were correlated using 52 five-year-olds whose IQs ranged from 40-136. The correlation between memory performance and IQ was .70 for whole sample, and .61 when children with IQs below 75 were omitted. Immediate recognition memory is highly associated with intelligence.

Educable mentally retarded (EMR) and nonretarded (NR) adolescents verified superordinate and basic level descriptions of common objects. Results suggest that EMR subjects had difficulty making semantic classification decisions in general. Other results suggest that group differences in semantic processing speed were related to the deliberate…
