In visual searches, stimuli following the law of good continuity attract attention to the global structure and receive attentional priority. Also, targets that have unique features are of high feature contrast and capture attention in visual search. We report on a salient global structure combined with a high orientation contrast to the…

In the present experiments, the question being addressed was whether switching attention between perceptual dimensions and selective attention to dimensions are processes that compete over a common resource? Attention to perceptual dimensions is usually studied by requiring participants to ignore a never-relevant dimension. Selection failure…

Under controlled conditions, we assessed acoustically (long-term average spectra) and perceptually (singer survey, listener survey) six performances of an soprano, alto, tenor, and bass (SATB) choir ("N" = 27) as it sang the same musical excerpt on two portable riser units (standard riser step height, taller riser step height) with…

Recent research indicates that perceptual learning (PL)--experience-induced changes in the way perceivers extract information--plays a larger role in complex cognitive tasks, including abstract and symbolic domains, than has been understood in theory or implemented in instruction. Here, we describe the involvement of PL in complex cognitive tasks…

This chapter addresses how child-, family-, and school-level characteristics are associated with Chinese children's academic skill development during their preschool years. Academic skills are defined in terms of young children's emergent competencies in academic domains including literacy, mathematics, and science. First, we review the relations…

Better understanding of the mechanisms underlying early reading skills can lead to improved interventions. Hence, the purpose of this study was to examine multivariate associations among reading, language, spoken phonological awareness, and fingerspelling abilities for three groups of deaf and hard-of-hearing (DHH) beginning readers: those who…

In a crowded dynamic world, temporal expectations guide our attention in time. Prior investigations have consistently demonstrated that temporal expectations speed motor behavior. We explore effects of temporal expectation on "perceptual" speed in three nonspeeded, cued recognition paradigms. Different hazard rate functions for the…

Autism spectrum disorder (ASD) is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion (RHI), which were therefore studied in high-functioning individuals with ASD and a…

Purpose: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, better known as CADASIL, is a rare, genetic form of early-onset vascular dementia. The purpose of this study was to use a modified version of Attention Process Training--II (APT-II; Sohlberg, Johnson, Paule, Raskin, & Mateer, 2001) with an…

We report 3 experiments that examined whether presentation of a spoken word creates an attentional bottleneck associated with lexical processing in the absence of a response to that word. A spoken word and a visual stimulus were presented in quick succession, but only the visual stimulus demanded a response. Response times to the visual stimulus…

Research on visual local and global perception in Autism Spectrum Disorder (ASD) is incomplete in young children. We investigated 35 three-year-old siblings of children with ASD, either diagnosed (n = 12) or not diagnosed (n = 23) with ASD as well as 14 controls with typical development and with no family history of ASD. Data from the local tasks…

This quantitative study examines how faculty service morale is related to faculty's social identities, organizational environments, and the three dimensions of faculty work-lives proposed by Johnsrud and Rosser (2002): professional priorities and rewards, administrative relations and support, and quality of benefits and services. Findings suggest…

This study investigated visual statistical learning (VSL) in 24 deaf signers and 24 hearing non-signers. Previous research with hearing individuals suggests that SL mechanisms support literacy. Our first goal was to assess whether VSL was associated with reading ability in deaf individuals, and whether this relation was sustained by a link between…

This article examines the complexity of the affordances that mobile technologies offer in the K-12 educational context. It builds on an ecological perspective (Mercer, 2012; van Lier, 2008) informed by theories of dynamic systems and complexity (Larsen-Freeman & Cameron, 2008) to explore the concept of affordance as a complex and dynamic…

Following the integration of an online homework tool--MyEnglishLab (MEL)--into their English courseware products, Pearson sought to explore how one of these products, Speakout, was being implemented with MyEnglishLab and perceptions about the impact it was having on learning. Speakout is a comprehensive eight-level General British English course…
