We investigated whether and when information conveyed by spoken language impacts on the processing of visually presented objects. In contrast to traditional views, grounded-cognition posits direct links between language comprehension and perceptual processing. We used a magnetoencephalographic cross-modal priming paradigm to disentangle these…

Pervasive developmental disorder not otherwise specified (PDD-NOS) represents up to two-thirds of autism spectrum disorders; however, it is usually described in terms of the symptoms not shared by autism. The study explores processing of neutral and emotional human stimuli (by auditory, visual and multimodal channels) in children with PDD-NOS (n =…

What cognitive processes influence how well we maintain information in visual short-term memory (VSTM)? We used a developmentally informed design to delve into the interplay of top-down spatial biases with the nature of the internal memory codes, motivated by documented changes for both factors over childhood. Seven-year-olds, 11-year-olds, and…

Background: Previous research has indicated that mood influences cognitive processes. However, there is scarce data regarding the link between everyday emotional states and readers' text processing and comprehension. Aim: We aim to extend current research on the effects of mood induction on science text processing and comprehension, using…

Introduction: This study explores blind users' unique help-seeking situations in interacting with digital libraries. In particular, help-seeking situations were investigated at both the physical and cognitive levels. Method: Fifteen blind participants performed three search tasks, including known- item search, specific information search, and…

This article examined the role of task demand and its effects on transfer in geographic learning. Student performance was measured through eye-movement analysis in two related experiments. In Experiment 1, the participants were told that they would travel through an area depicted in photographs either driving an automobile or observing the…

The purpose of the proposed study is to add to the literature regarding the assessment of effort and malingering in the field of neuropsychology using the Rey Complex Figure Test (RCFT). The majority of the literature on this measure has been in the specific areas for which the instrument was developed, namely those of visual spatial and…

This petition is about two of the traditional three R's - reading, writing, and arithmetic; it concerns learning letter formation and learning to read, both of which require continuous interplay between the different perceptual attunements of central and paracentral areas of the retina. This interplay, managing the field of view between zooming-in…

Robust control of skilled actions requires the flexible combination of multiple sources of information. Here we examined the role of gaze during high-speed locomotor steering and in particular the role of feedback from the visible road edges. Participants were required to maintain one of three lateral positions on the road when one or both edges…

What mechanism implements the mutual exclusivity bias to map novel labels to objects without names? Prominent theoretical accounts of mutual exclusivity (e.g., Markman, 1989, 1990) propose that infants are guided by their knowledge of object names. However, the mutual exclusivity constraint could be implemented via monitoring of object novelty…

Presenting a face inverted (upside down) disrupts perceptual sensitivity to the spacing between the features. Recently, it has been shown that this disruption is greater for vertical than horizontal changes in eye position. One explanation for this effect proposed that inversion disrupts the processing of long-range (e.g., eye-to-mouth distance)…

Visual working memory (VWM) is the facility to hold in mind visual information for brief periods of time. Developmental studies have suggested an increase during childhood in the maximum number of complete items that can simultaneously be stored in VWM. Here, we exploit a recent theoretical and empirical innovation to investigate instead the…

White (2012) proposed that kinematic features in a visual percept are matched to stored representations containing information regarding forces (based on prior haptic experience) and that information in the matched, stored representations regarding forces is then incorporated into visual perception. Although some elements of White's (2012) account…

The role of context was examined in the selection and integration of independently learned spatial relationships. Using a dynamic 3D virtual environment, participants learned one spatial relationship between landmarks A and B which was established in one virtual context (e.g., A is left of B) and a different spatial relationship which was…

Limits in visual working memory (VWM) strongly constrain human performance across many tasks. However, the nature of these limits is not well understood. In this article we develop an ideal observer analysis of human VWM by deriving the expected behavior of an optimally performing but limited-capacity memory system. This analysis is framed around…
