Performance on a wide variety of memory tasks can be hypothesized to be influenced by processes associated with controlling the contents of memory. In this project 328 adults ranging from 18 to 93 years of age performed six tasks (e.g., multiple trial recall with an interpolated interference list, directed forgetting, proactive interference, and…

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and…

To examine effects of input and learner characteristics on morphology acquisition, 60 adult English speakers learned to inflect masculine and feminine Russian nouns in nominative, dative, and genitive cases. By varying training vocabulary size (i.e., type variability), holding constant the number of learning trials, we tested whether learners…

An attempt is made, using a partial review of the literature, to present a non-technical overview of some of the child-related issues in simultaneous bilingualism. While controversy still rages in the area of bilingualism research, some definite changes can be discerned over the past 40 years. Opinion has shifted from a deficiency perspective to…

The research looking for cognitive factors specific to depression has resulted in the consistent finding that memory in depression is selective. The phenomenon of selective memory for negative events in depression was investigated using signal detection methods to separately examine the contributions of information processing deficits and response…

The effects of musical accompaniment on two different visual information processing activities were examined in individuals of differing selected personality types. The Myers Briggs Type Indicator Form G was administered to classes of University students. From the results, four subgroups, the sensing-thinking, sensing-feeling, intuitive-feeling,…

A model was tested in which it was assumed that the left and right cerebral hemispheres have access to independent supplies of resources, which they may use in most kinds of information processing situations. Eight male subjects were specifically selected for having demonstrated a strong right-hand superiority on several manual tasks, and a strong…

Information about individuals' representations of problems was obtained from studies on reasoning and problem categorization. College students (N=62) participated in a study of the transition from concrete to formal reasoning using the pendulum and chemical yellow tasks. Over a 10-12 week period, 47 students participated in 10 training sessions on…

One hundred twelve college students participated in a study designed to determine whether students differ in their relative employment of knowledge-based processes in discourse processing and whether individuals tend to be more "text-bound" and less able to use preexisting knowledge schemata when they are more "stimulus-bound"…

Previous research on the nature of aptitude processes had ignored the important differences between speed and level of performance. However, investigations of the relationship between individual differences in speed and level suggest that speed of solving simple spatial tasks is largely independent of level attained on more complex spatial tasks.…

An exploratory study was undertaken to provide a means of quantifying some of the components of the problem solving process. The focus was on actual problem solving behaviors and strategies as they occurred in relation to different cognitive tasks and subject characteristics. Cognitive tasks included items from Wechsler and Binet intelligence…

This study investigates the perceptual processing capabilities by analysis of eye movement of children from differing levels of field independence/dependence. Forty nine field independent (24 girls, 26 boys) and 36 field dependent (19 girls, 17 boys) children in third grade were analyzed as they viewed either seven dynamic or seven static segments…

Albert Michotte, known primarily for his research in perception, also carried out several experiments in logical memory (conceptual or intellectual memory). He was strongly influenced by Kulpe, feeling that the thought processes were autonomous, in contradiction to more traditional and elementary conceptions of mental activity. His experiments,…

As part of a long term project relating individual differences in performance on paper and pencil tests of intellectual aptitude and achievement to differences observed in laboratory studies of cognition, data have been collected comparing test scores with simple choice reaction times. The three studies summarized here suggest that the…

This paper presents an overview of the knowledge afforded man from research into personality. Approaching his topic from a position valuing the study of persons from complementary psychological perspectives, the author attempts to derive some conclusion about human behavior and personality. He discusses the findings that there is basic continuity…
