Purpose: In this study, the authors investigated (a) the effects of task, vocal distinctiveness of the competing talkers, and meaningfulness of the competitor on older listeners' identification of a target in the presence of competition and (b) the factors that are most predictive of the variability in target identification observed among older…

Although some views of face perception posit independent processing of face identity and expression, recent studies suggest interactive processing of these 2 domains. The authors examined expression-identity interactions in visual short-term memory (VSTM) by assessing recognition performance in a VSTM task in which face identity was relevant and…

Consonance and dissonance are subjective perceptions that are reactions of the human ear to whether or not musical intervals sound "pleasing." The physical causes of consonance and dissonance are not as well understood as other subjective properties of sound perceived by the ear such as pitch, loudness, and quality (timbre). What follows is an…

Like language, music engagement is universal, complex and present early in life. However, approximately 4% of the general population experiences a lifelong deficit in music perception that cannot be explained by hearing loss, brain damage, intellectual deficiencies or lack of exposure. This musical disorder, commonly known as tone-deafness and now…

Background: The phenomenon of change blindness illustrates that a limited number of items within the visual scene are attended to at any one time. It has been suggested that individuals with autism focus attention on less contextually relevant aspects of the visual scene, show superior perceptual discrimination and notice details which are often…

The environment at indoor inflatable playgrounds, featuring giant bounce houses and slides, can become an ideal place for children with autism to receive helpful sensations. This is the reasoning behind Sensory Nights hosted by the Autism Society of America and Pump It Up, a national franchise of giant, indoor inflatable playgrounds. The private…

We comment on Goldstein, Davidoff, and Roberson's replication and extension ("Journal of Experimental Child Psychology, 102", 219-238 [2009]) of our study of the effect of toddlers' color term knowledge on their categorical perception (CP) of color ("Journal of Experimental Child Psychology, 90", 114-141 [2005]). First, we discuss how best to…

New tactile curriculum materials for teaching Earth and planetary science lessons on rotation=revolution, silhouettes of objects from different views, contour maps, impact craters, asteroids, and topographic features of Mars to 11 elementary and middle school students with sight impairments at a week-long residential summer camp are presented…

This research investigates whether English speakers who learn Mandarin Chinese via a familiar orthography differ from those who learn via a non-familiar orthography in their perception of English-Mandarin sound pairs. Canadian English speakers (n = 32) participated in a series of experimental tasks. The tasks included pre- and posttest perception…

Background: This study examined students' perceptions of autonomy-supportive teaching (AST) and its relations to internalization of pro-social values and bullying in class. Aims: We hypothesized that: (1) teachers' AST, which involves provision of rationale and taking the student's perspective, would relate positively to students' identified…

Children who begin kindergarten with stronger skills learn faster than do those who enter with lower skills. Minority children tend to enter kindergarten already at a disadvantage, and the gap widens across time. However, little is known about cognitive development among American Indian young children. In this study, 110 American Indian infants…

Purpose: Bilingual aphasia generally affects both languages. However, the age of acquisition of the second language (L2) seems to play a role in the anatomo-functional correlation of the syntactical/grammatical processes, thus potentially influencing the L2 syntactic impairment following a stroke. The present study aims to analyze the influence of…

Individual differences in abilities to form, access, and hone phonological representations of words are implicated in the development of oral and written language. This study addressed three important gaps in the literature concerning measurement of individual differences in phonological representation. First, we empirically examined the…

Aim: To describe neuropsychological disturbances and the developmental course associated with cerebellar cortical dysplasia (CCD). Method: The neuroimaging findings from 10 children (five males, five females; aged 3-10y) with CCD were reviewed and classified. These children all underwent clinical neurological examination and neuropsychological…

Barely 30 years on from the advent of distance learning as we recognise it today, it has already become uncommon for a learner to embark on a programme of education that does not involve frequent access to the Internet; but if a course does not revolve around the Internet, is it in any way inferior and is the learner disadvantaged? Two of the…
