Classic studies in cognition have demonstrated that the use of appropriate memory mnemonics can reliably increase recall performance. However, is the facilitative effect of mnemonics consistent across all individuals? As some mnemonics explicitly contain a large visuospatial component, does normal variance in visuospatial aptitudes predict the…

Computational thinking requires high cognitive load as students work to manage multiple tasks in their problem-solving environment. Through research in K-2 classrooms on computational thinking, we noticed that students lack the representational fluency needed to move from one form to another--such as moving from physical to more abstract…

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were…

In this study we investigated whether the beneficial effect of adding illustrations to text can be explained by the fact that illustrations facilitate analogous mental representation construction from text in visuospatial working memory. For this the secondary task paradigm was used. It was expected that the secondary task interfered only with…

Adolescence is a developmental period characterized by a complex maturation process of various cognitive abilities. Cognitive control, which includes response inhibition and working memory, is one of them. A typical study on response inhibition to visual stimuli presents distractors and targets on the same display (e.g., the computer screen).…

The Australian Geography Competition (AGC) was established in 1995 by the Royal Geographical Society of Queensland (RGSQ) and the Australian Geography Teachers' Association to promote the study of geography in Australian secondary schools and to reward student excellence in geographical studies. Initially focusing on students at the lower…

This paper reports the results of four dual-task experiments that were designed to determine the extent of domain-specificity of the verbal working memory resources used in linguistic integrations. To address this question, syntactic complexity was crossed in a 2x2 design with the complexity of a secondary task, which involved either (1)…

With first-grade and college students, examines barrier effects as a function of the task used to assess subjects' cognitive maps. One group, asked to give rank-ordering judgments, had to keep an entire spatial layout in mind. The second group made direct estimates of the distance between two objects. (RH)

Three studies examined the hypotheses that: (1) codability and not extent of distance determines difficulty; (2) critical features and not whole objects are coded; and (3) implicit perceptual axes provide a frame of reference for coding the display. Results supporting these hypotheses are discussed in terms of a description of spatial…

The nature of the message used by children, 4 1/2 and 6 1/2 year-old, was studied in a spatial description task. Speaker and listener were separated from one another by an opaque screen, and had to exchange information. Speaker were asked to describe a board showing eight objects placed in a room, and listeners were instructed to draw a similar…

Four new versions of an acoustic structuring test were developed, administered, and analyzed in order to produce better tests and to contribute to better understanding of the abilities measured by these tests. The tests consist of tape recordings of patterns of musical notes played on an electric organ or an acoustic guitar. Item analyses and…
