Investigates the role of morphological structure in the representation and processing of Mandarin Chinese compounds. Results provide evidence against single-layer, morpheme-based models of the Chinese mental lexicon, pointing instead to a two-layer, whole-word and morphemic model (the Multi-Level Cluster Representation Model).

Reports on the perceptual discrimination of segmental and suprasegmental phones by Japanese learners of English. Results reveal that early learners showed better discrimination performance than normal learners and confirmed the usefulness of learning English at an early age. (16 references) (Author/CK)

This article discusses the results of a case study that investigated the effectiveness of an auditory prompting system, using earphones and a cassette, to improve on-task job performance of an adult with mild mental retardation. Guidelines for working with adults and student to improve job and task performance are provided. (Contains references.)…

Despite the seminal studies of response differentiation by the method of successive approximation detailed in chapter 8 of "The Behavior of Organisms" (1938), B. F. Skinner never actually shaped an operant response by hand until a memorable incident of startling serendipity on the top floor of a flour mill in Minneapolis in 1943. That occasion…

In traditional psychoanalysis, patients recline on a couch in a way that prevents patients and analysts from seeing each other's faces. This has been argued to have significant effects, both positive and negative, on patients' treatment. The use of the couch creates an unusual communicative situation in which both parties are physically but not…

"Picture Exchange Communication System" (PECS) training was implemented with 5 nonspeaking adults with mental retardation who were not currently using any type of functional communication system. A modified ABAB, single-subject design was used to assess the effectiveness of PECS in enhancing the functional communication skills of these…

Background: Rett syndrome (RS) is a pervasive developmental disorder with cognitive and neuromotor impairments (including loss of handiness and loss of communicative skills). Objective: To verify whether girls with RS use their gaze intentionally, by observing their performance in three cognitive tasks: (1) verbal instruction condition (look at…

Background: There is growing literature suggesting that some children diagnosed with attention deficit hyperactivity disorder (ADHD) can show a significant bias in attention away from left space. Here we examine mechanisms that may underpin these effects in both clinical and non-clinical child populations. Unilateral spatial inattention…

While much time has been spent deliberating about the definition of play, little emphasis has been placed on what children themselves perceive as play. The aim of the present study was to examine social context as a cue for children's perceptions of play and learning. Ninety-two children aged between four and six years (mean four years nine…

Virtual Reality (VR) is primarily a visual technology. Elements such as haptics (touch feedback) and sound can augment an experience, but the visual cues are the prime driver of what an audience will experience from a VR presentation. At its inception in 2001 the Centre for Advanced Visualization (CFAV) at Niagara College of Arts and Technology…

Rodrigo, Chamizo, McLaren, & Mackintosh (1997) demonstrated the blocking effect in a navigational task using a swimming pool: rats initially trained to use three landmarks (ABC) to find an invisible platform learned less about a fourth landmark (X) added later than did rats trained from the outset with these four landmarks (ABCX). The aim of the…

Synaptic plasticity is thought to contribute to memory formation. Serotonin-induced facilitation of sensory-motor (SN-MN) synapses in "Aplysia" is an extensively studied cellular analog of memory for sensitization. Serotonin, a modulatory neurotransmitter, is released in the CNS during sensitization training, and induces three temporally and…

This paper reports the effects of communication strategy instruction on second language performance (communicative success, speech rate, message abandonment) and on the use of communication strategies (paraphrase). Two classes of adult immigrants, enrolled in a full-time intermediate proficiency ESL program at a post-secondary institution in…

Although drawing has been used as research tool for well over a century in the fields of psychology and anthropology, drawing remains overlooked and underutilized in educational research. This article examines the promise of visual methods, and of drawing in particular, in accessing middle schoolers' perceptions as a means of informing the middle…

This study examined the cognitive and neural development of attention switching using a simple forced-choice attention task and functional magnetic resonance imaging. Fourteen children and adults made discriminations among stimuli based on either shape or color. Performance on these trials was compared to performance during blocked trials…
