Some potential contributions of invariants, heuristics, and exemplars to the perception of dynamic properties in the colliding balls task were explored. On each trial, an observer is asked to determine the heavier of 2 colliding balls. The invariant approach assumes that people can learn to detect complex visual patterns that reliably specify…

In three structural priming experiments, we investigated temporarily ambiguous sentences such as "While the man was visiting the children who were surprisingly pleasant and funny played outside." Participants produced more transitive sentences following such temporarily ambiguous sentences than following unambiguous sentences that were…

With the emerging population of the oldest-old (those ages 85 and older), it is crucial to understand and prepare for their psychosocial needs. Worry is linked to psychological well-being and physical health, but little is known about the oldest-old's everyday worries. The authors explored four research questions: (1) What are the worries of the…

Four experiments investigated the nature of spatial representations used in locomotion. Participants learned the layout of several objects and then pointed to the objects while blindfolded in 3 conditions: before turning (baseline), after turning to a new heading (updating), and after disorientation (disorientation). The internal consistency of…

Previously it has been reported that female performance on the recall of objects and their locations in a spatial array is superior to that of males. This may reflect underlying information-processing biases whereby males organize information in a self-referential manner while females adopt a more comprehensive approach. The known female advantage…

The immediate written recall task, a widely used measure of both first language (L1) and second language (L2) reading comprehension, has been advocated over traditional test methods such as multiple choice, cloze tests and open-ended questions because it is a direct and integrative assessment task. It has been, however, criticized as requiring…

Our research on learning enhancement has been focusing on the consequences for learning and forgetting of some of the more obvious and concrete choices that arise in instruction, including: How does spacing of practice affect retention of information over significant retention intervals (up to two years)? Do spacing effects generalize beyond…

A mini-lesson in Spanish vocabulary was taught to undergraduates unfamiliar with the language using one of two predominant L2 teaching methodologies, the grammar-translation approach or the communicative approach. Both experimental groups showed significant improvement in learning the target language over the baseline measure set by the control…

Background: Studies of language in children with mild-to-moderate hearing impairment (HI) indicate that they often have problems in phonological short-term memory (PSTM) and that they have linguistic weaknesses both in vocabulary and morphosyntax similar to children with specific language impairment (SLI). However, children with HI may be more…

Few studies have examined the ability of individuals with learning disabilities, in general, or with Down syndrome, specifically, to discriminate speech. The purpose of this study was compare the speech discrimination abilities of eight children with Down syndrome (aged 5.7 to 12.8 years) to seven nonverbal mental-age matched controls (aged 4.0 to…

Overview: Behavioural data reveal an inverted U-shaped function in the efficiency of prospective memory from childhood to young adulthood to later adulthood. However, prior research has not directly compared processes contributing to age-related variation in prospective memory across the lifespan, hence it is unclear whether the same factors…

Historically, sensory systems have been largely ignored as potential loci of information storage in the neurobiology of learning and memory. They continued to be relegated to the role of "sensory analyzers" despite consistent findings of associatively induced enhancement of responses in primary sensory cortices to behaviorally important signal…

Many educators agree that pre-service teachers bring into their teacher education programs previously constructed ideas and beliefs about students, teaching, and learning. They contend that it may be difficult for students to change these constructs when participating in a teacher education program whose views of instruction are not congruent with…

In this article, the authors review learning and behavioral problems of children exposed prenatally to alcohol and other drugs, focusing on executive-function deficits such as difficulty shifting tasks, maintaining attention, and manipulating information in working memory. They discuss various risk factors associated with prenatal drug exposure so…

It has been suggested that the high levels of comorbidity between attention-deficit-hyperactivity disorder (ADHD) and developmental coordination disorder (DCD) may be attributed to a common underlying neurocognitive mechanism. This study assessed whether children with DCD and ADHD share deficits on tasks measuring working memory, set-shifting, and…
