Background: Individual differences in complex working memory tasks reflect simultaneous processing, executive functions, and attention control. Children with specific language impairment (SLI) show a deficit in verbal working memory tasks that involve simultaneous processing of information. Aims: The purpose of the study was to examine executive…

The aim of the study was to examine how goal-setting skills of children with attention-deficit/hyperactivity disorder (ADHD) can be predicted with elements of working memory. The study involved 30 children with an ADHD diagnosis and 30 healthy volunteers. The IQ of the participants was assessed, and ADHD symptoms were evaluated by parents. Each of…

Two experiments were conducted to investigate six-month-old infants' recognition memory for the shape of an object following unimodal (visual) and bimodal (visual and haptic) familiarization. Visual recognition memory was evident only when the conditions of familiarization and testing were identical. Two possible explanations are presented and…

Geometry is required for many secondary school students, and is often learned, taught, and assessed more in a heuristic image-based manner, than as a formal axiomatic deductive system. Students are required to prove general theorems, but diagrams are usually used. It follows that understanding how students engage in perceiving and reasoning about…

This literature review focuses on the confirmed, suspected, and speculative effects of violent and non-violent video game exposure on negative and positive outcomes. Negative outcomes include aggressive feelings, aggressive thoughts, aggressive behavior, physiological arousal, and desensitization, whereas positive outcomes include various types of…

This study was designed to determine the relationship between the Lowenfeldian visual-haptic (perceptual) and the Piagetian concrete-formal (operational reasoning) continua. The study also investigated the relationship between age, sex, academic goal, academic preference, and a person's perceptual aptitude or intellectual reasoning abilities.…

Paper presented at the International Seminar on Experimental Research in Music Education (University of Reading, Reading, England, July 9-16, 1968).

This report is the first in a two-part series introducing an interactive activation model of context effects in perception. A model for the perception of letters in words and other contexts is described and applied to a number of experiments. It is proposed that the model accounts for (1) the perceptual advantage for letters in words compared to…

This report is the second in a two-part series introducing an interactive activation model of context effects in perception. In the first part, a model for the perception of letters in words and other contexts was described and applied to a number of experiments. This second part applies the same model to a number of new experiments designed to…

Talks presented by Doris Johnson and Regina Cicci at an institute for teachers of the educationally handicapped are summarized and include identification and remediation of auditory receptive language disorders, disorders of spelling and written language, an analysis of reading methods, an analysis check list, disorders of quantitative thinking,…

Investigating the effects of marijuana on human psychological functioning, this study differs from previous research in two ways: 1) it is concerned with relatively complex cognitive processes; 2) it has a theoretical rationale. The general hypothesis of the study states that marijuana will impair its user's ability to form and use abstract…
