Although the accuracy of the diagnosis of cognitive impairment in the elderly depends on the appropriateness of the norms for the neuropsychological tests used, the importance of examining health status, native intelligence, and gender when attempting to describe cognitive changes of aging has received little attention. The Rey Auditory Verbal…

The development of scripts and their use for guiding memory was examined in children ages 3 to 5 and 7 to 9. In the first phase of the study, 10 preschool children and 10 elementary school students were asked to describe three scripts related to everyday life. Scripts were analyzed to determine whether any differences existed between those of…

Age differences in intellect as reflected by performance on the Wechsler Adult Intelligence Scale (Revised) (WAIS-R) were evaluated for persons aged 20 to 74 years. Educational attainment levels were held constant. The WAIS-R sample included 1,480 men and women in the following seven age groups--20-24 years (n=250), 25-34 years (n=250), 35-44…

A study examined the connection between the everyday activities of adults of different ages and their performance on a prose recall task. Subjects were 54 adults, 18 in each of three age groups (18-32, 40-54, and over 62). Written recall of two 388-word expository prose passages was used for the prose recall measure. For the activities measures,…

Cognitive self-instructional (CSI) programs have been successful in improving problem-solving skills in many, but not all, children. The importance of understanding the influence of subject characteristics in self-control studies, while often ignored in actual research, has been repeatedly advocated verbally. This paper presents a study designed…

Children's performance on multidimensional classification tasks was examined in two experiments. In Experiment 1, preschool, first-, and third-grade children were shown a standard stimulus and were then asked to judge whether several comparison stimuli were the same as or different from the standard. Comparison stimuli differed from the standard…

In 2 experiments, 261 middle school students processed an analogy and responded to factual and inferential target-domain questions in a study of variables that contribute to the formation of analogical misconceptions. Results of both experiments support a six-variable model of analogical misconception formation. (SLD)

Exploring whether deductive reasoning can develop adequately without special instruction, this paper presents two studies that examine the development of meta-components of deductive reasoning, first in algebra, and second in verbal reasoning. The first study examined students' understanding of logical necessity in algebraic tasks in different…

A major issue concerning adult intellectual development is whether intellectual decline in late adulthood is uniform or ability-specific. Differential patterns of ability decline were analyzed by comparing data on longitudinal age change over the age range from 53 to 81 years from two successive 14-year periods (1956-1970 and 1970-1984). The…

Two levels of stimulus condition were used to determine whether or not the amount of salient information contained in the perceptual stimuli accompanying orally presented "wh-questions" (those including the concepts who, what, where, when, how and why) facilitates children's comprehension. Conditions varied in terms of the number of…

Fully addressing most problems clients bring to therapy usually requires more than one session. Some student therapists seem to be more capable than others of engaging clients and promoting more visits when warranted. To discover whether graduate admissions information can predict a psychologist-trainee's ability to readily engage clients, data…

Two experiments investigated the role of children's assessments of their performance on their decisions to seek help and their preferences for different types of assistance. Blocked into low and high verbal skill groups, participants in study 1 were 84 middle-class third- and fifth-grade elementary school students. Subjects performed a multi-trial…

The internal consistency reliability and discriminant validity of the adult version of the Matching Familiar Figures Test (MFF) were determined for a sample spanning adulthood; age and sex differences were also investigated. Sixty-three men and 63 women ranging from 18 to 78 years of age, with at least 12 years of schooling, were administered…

This study examining children's ability to organize information for the purpose of recall was designed to control for verbal ability differences. The participants were 10 boys and 10 girls each from kindergarten, 2nd, 4th and 6th grades. A modified "Simon Says" game was used to enable the children to respond to eight selected verbal and motor…

Analysis of 165 studies (representing the testing of 1,418,899 subjects) that reported data on gender differences in verbal ability indicated a slight female superiority in performance. The difference is so small that it appears that gender differences in verbal ability no longer exist. A major goal was also to define age trends in the pattern of…
