Background: This article considers the impact of differential task difficulty on student engagement and progression within an Irish primary school context. Gaining and maintaining student engagement during learning tasks such as homework is a significant and understandable on-going challenge for teachers. The findings of this study hold the…

Previous findings of a developmental trend from holistic to analytic modes of processing are subject to two possible interpretations: the ability to analyze according to dimensions increases with age, or a production deficiency for the strategy of analyzing decreases with age. This study tests these interpretations through an examination of…

This study found that 13 autistic subjects performed less well on cognitive than on visual perspective-taking tasks at two levels of difficulty. Autistic subjects performed as well as 13 intellectually handicapped controls and 13 normal controls on visual perspective-taking tasks but more poorly than controls on cognitive perspective-taking tasks.…

Four experiments investigated the development of visuomotor control in sequential pointing in tasks varying in difficulty among 6- to 10-year-olds and adults. Comparisons across difficulty levels and ages suggest that motor development is not a uniform fine-tuning of stable strategies. Findings raise argument for stage characteristics of…

On the basis of teachers' ratings of impulsivity, a group of 20 preschool children with a mean age of 51 months were assigned to groups of impulsive and non-impulsive subjects. Both groups were administered two measures of impulsivity as pre- and posttests: the Draw-a-Line Test and an adapted version of the Matching Familiar Figures Test. In…

Two experiments examined problem solving in 16-month-olds' adaptive locomotion (crossing bridges of varying width with/without handrail). Findings indicated that toddlers attempted wide bridges more than narrow ones. Attempts on narrow bridges depended on handrail presence. Toddlers had longer latencies, examined bridge/handrail more closely, and…

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

Adults' ability to track a moving target was examined in two experiments in order to compare their performance with that of very young infants. Results indicated that (1) adults'"overshoot" errors resembled those reported for young infants; and (2) adults had problems tracking a moving target which unexpectedly changed direction.

Three studies investigated preschoolers' reasoning about ability. Findings suggested sensitivity to mental state information when judging another child's ability, and they perceived positive correlations between effort and academic success, and "niceness" and high academic ability. Comparisons with 9- to 10-year-olds suggest that…

Previous studies have shown that, when administered a self-adapted test, a few examinees will choose item difficulty levels that are not well-matched to their proficiencies, resulting in high standard errors of proficiency estimation. This study investigated whether the previously observed effects of a self-adapted test--lower anxiety and higher…

The roles of training, problem representation, and individual differences on performance of both automated (simple) and controlled (complex) process tasks were studied. The following hypotheses were tested: (1) training and cognitive style affect the representation developed; (2) training and cognitive style affect the development and performance…

Visual and auditory processing of complex sentences was examined among 8- through 11-year-olds. Findings suggested a U-shaped learning pattern for on-line processing of restrictive relative clauses. Off-line accuracy scores showed different patterns for good and poor comprehenders. Incorrect local attachment strategy use was related to sentence…

A computerized adaptive testing model was assessed in a technical training system. The model, a modification of Lord's flexilevel paradigm, consisted of: the sequencing of test items in a difficulty hierarchy, adaptive entry of students into the test at a difficulty level appropriate to their predicted score, and systematic movement of students…

Two studies were conducted to examine teachers' and young children's perceptions of persistence in classroom settings. In the first, 35 elementary school teachers responded to interview questions about (1) the appropriateness of persistence in relation to other strategies children could use to accomplish difficult tasks, (2) children's…

Two experiments examined the use of a number-line metaphor presented with interactive multimedia to help sixth graders with varying levels of mathematics achievement or spatial ability build connections between addition and subtraction of signed numbers and existing conceptual knowledge. Results indicated that use of multiple representations…
