Traced emergence of elaborated framework of belief-desire reasoning. Preschoolers and adults were asked to explain why a story protagonist searched for a desired object in an incorrect location. Results suggest that, during late preschool years, conception of cognitive activities as contributing to knowledge and belief becomes integrated into…

The performance of eight adults with Asperger syndrome was compared with the performance of controls on a range of perceptual tasks designed to test two models of perceptual deficit: the central coherence deficit model and the hierarchization deficit model. Tentative support for the hierarchization deficit model was demonstrated. (Contains ten…

Two experiments used phoneme counting tasks to investigate the foundations of phonemic awareness. Found that first graders and college students had some ability to distinguish between monophthongs (as in "he") and diphthongs (as in "how"), and they tended to count fewer "sounds" for syllables ending with the more…

Two experiments examined the effects of a culture-general factor, pattern redundancy, on the discrimination of five-tone melodies that differed in their adherence to Western tonal conventions, among 9-month olds, 5-year olds, and adults. Increasing exposure seemed to attenuate the effects of the pattern redundancy while amplifying the influence of…

Three experiments examined cross-modal transfer of shape between touch and vision in 1-month-olds, controlling for side bias and stimulus preference. Results did not provide good evidence that 1-month-olds can transfer information about smooth or nubby shapes from touch to vision. Findings highlight the need to control for side bias and stimulus…

Tested in two studies 4- to 7-year-olds' face recognition by manipulating the faces' configural and featural information. Found that even with only a single 5-second exposure, most children could use configural and featural cues to make identity judgments. Repeated exposure and feedback improved others' performance. Even proficient memories were…

In this article we describe a new classroom exercise for introducing the actor-observer bias in social perception. We describe 2 experiments that compared our new technique (which involves resolving interpersonal dilemmas for oneself and another) with a previously established technique (judging the applicability of traits for oneself and another).…

Recent research suggests that outcome additivity pretraining modulates blocking in human causal learning. However, the existing evidence confounds outcome additivity and outcome maximality. Here the authors present evidence for the influence of presenting information about outcome maximality (Experiment 1) and outcome additivity (Experiment 2) on…

Research suggests that, using representations from object-based attention, infants can represent only 3 individuals at a time. For example, infants successfully represent 1, 2, or 3 hidden objects, but fail with 4 ("Developmental Science" 6 (2003) 568), and a similar limit is seen in adults' tracking of multiple objects (see "Cognitive Psychology"…

Two processes have been hypothesized to underlie improvement in perception: attunement and calibration. These processes were examined in a dynamic touch paradigm in which participants were asked to report the lengths of unseen, wielded rods differing in length, diameter, and material. Two experiments addressed whether feedback informs about the…

How do infants identify the psychological actors in their environments? Three groups of 12-month-old infants were tested for their willingness to encode a simple approach behavior as goal-directed as a function of whether it was performed by (1) a human hand, (2) a morphologically unfamiliar green object that interacted with a confederate and…

The relation between perceptual organization and categorization processes in 3- and 4-month-olds was explored. The question was whether an invariant part abstracted during category learning could interfere with Gestalt organizational processes. A 2003 study by Quinn and Schyns had reported that an initial category familiarization experience in…

Children with congenital blindness are delayed in understanding other people's minds. The present study examined whether this delay was related to a more primitive form of inter-subjectivity by which infants draw correspondence between parental mirroring of the infant's display and proprioceptive sensations. Twenty children with congenital…

Early intervention approaches for facilitating motor development in infants and children with Down syndrome have traditionally emphasised the acquisition of motor milestones. As increasing evidence suggests that motor milestones have limited predictive power for long-term motor outcomes, researchers have shifted their focus to understanding the…

Educational taxonomies developed by Bloom, Krathwohl, and collaborators have been used for decades as frameworks for instructional objectives, curriculum design, and assessments of achievement. However, their scope is now too limited. The well-known cognitive domain is extended to include ideational functions of imagination and creativity, and the…
