The simplest attentional task, detecting a cued stimulus in an otherwise empty visual field, produces complex patterns of performance. Attentional cues interact with backward masks and with spatial uncertainty, and there is a dissociation in the effects of these variables on accuracy and on response time. A computational theory of performance in…

Based on Activity Theory, this article examines attitude formation in human learning as shaped by the experiences of individual learners with various learning objects in particular learning contexts. It hypothesizes that a learner's object-related perceptions, personality traits and situational perceptions may have different relationships with the…

Because concrete explanations in a familiar context facilitate understanding, we illustrate the concept of an interaction via a baking analogy to provide students with food for thought. The demonstration initially introduces the concepts of independent and dependent variables using a chocolate chip cookie recipe. The demonstration provides an…

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…

The relationships of sense modalities included in the broad term "perception" are explored. Vision is a transmission from external world to brain. Ocular mobility and spatial organization abilities are important to vision as it is involved in the perceptual-cognitive process. Kinesthetic and visual behaviors are interrelated and are supplemented…

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…
