Black and white kindergarten and second-grade children were tested for accuracy of detection and recognition of orientation and location changes in pictures of real-world and geometric figures. The purpose was to test children's ability to detect and remember objects in a visual display. (Author/CS)

Two experiments were conducted to investigate the relationships between individual difference variables and discovery vs. non-discovery instructional treatments in learning of an imaginary science. All subjects were able to learn the material, but presentation of examples and rules (non-discovery) led to more rapid learning. There was no…

Examines the relation between attention to target and context information and target recall in an incidental learning task for children and adults. Results support a distinction between context-interactive and context-independent situations and suggest that the attentional patterns that are efficient for memory may differ with the kind of…

This study compared 112 younger and older adult monolingual English speakers and English/Spanish bilingual speakers on measures of auditory perception and memory span. The results revealed no age difference in auditory memory span in English but found that both older and younger bilinguals performed better than monolinguals on these tasks.…

Background: Tourette's syndrome (TS) is a neurodevelopmental disorder associated with fronto-striatal dysfunction. There is debate as to the extent to which TS is associated with cognitive impairment. Some authors argue that any impairments seen are attributable to comorbid psychiatric symptomatology, whilst others have suggested that…

The aim of this study was to evaluate the role of short-term memory and attention in time estimation. For this purpose we studied prospective time verbal estimation in 21 patients with Alzheimer's disease (AD), and compared their performance with that of 21 matched normal controls in two different conditions: during a digit span task and during an…

Information storage in the brain is a temporally graded process involving different memory phases as well as different structures in the mammalian brain. Cortical plasticity seems to be essential to store stable long-term memories, although little information is available at the moment regarding molecular and cellular events supporting memory…

The cAMP/PKA pathway plays a critical role in learning and memory systems in animals ranging from mice to "Drosophila" to "Aplysia." Studies of olfactory learning in "Drosophila" suggest that altered expression of either positive or negative regulators of the cAMP/PKA signaling pathway beyond a certain optimum range may be deleterious. Here we…

The degree to which native and non-native readers interpret English sentences incrementally was investigated by examining plausibility effects on reanalysis processes. Experiment 1 required participants to read sentences word by word and to make on-line plausibility judgements. The results showed that natives and non-natives immediately computed…

Low-frequency words produce more hits and fewer false alarms than high-frequency words in a recognition task. The low-frequency hit rate advantage has sometimes been attributed to processes that operate during the recognition test (e.g., L. M. Reder et al., 2000). When tasks other than recognition, such as recall, cued recall, or associative…

This paper discusses two related areas in which recent advancements in cognitive science and educational technology may affect instructional design theory. These are: (1) the analysis of information-to-be-learned; and (2) the linkage of learning theory to instructional prescriptions. The first area proposes extensions to current methods of…

Five studies were conducted to investigate the relationship between short term memory (STM) and long term memory (LTM), and the relationship between STM and problem solving. In study I, the necessity of postulating separate learning processes for tasks which are traditionally classified as STM tasks as opposed to LTM tasks was investigated.…

Ninety-eight undergraduate education majors received a battery of ability tests, measuring general reasoning, associative memory, and trait anxiety and were randomly assigned to three groups--no feedback, feedback, and learner control--for a computer-assisted instruction course on Xenograde systems (an imaginary science). Four state anxiety…

Words and pictures with earlier learned labels are processed faster than words and pictures with later learned labels. This age-of-acquisition (AoA) effect has been extensively investigated in many different types of tasks. This article provides a review of these studies including picture naming, word naming, speeded word naming, word…

Clahsen and Felser (CF) analyze the performance of monolingual children and adult second language (L2) learners in off-line and on-line tasks and compare their performance with that of adult monolinguals. They conclude that child first language (L1) processing is basically the same as adult L1 processing (the contiguity assumption), with…
