Previous studies provide empirical support for the reported colour experience in grapheme-colour synaesthesia by measuring the synaesthetic experience from an externally presented grapheme. The current study explored the synaesthetic experience resulting from a visual mental image of a grapheme. Grapheme-colour synaesthetes (N=6) and matched…

Ocular pursuit movements allow moving objects to be tracked with a combination of smooth movements and saccades. The principal objective is to maintain smooth eye velocity close to object velocity, thus minimising retinal image motion and maintaining acuity. Saccadic movements serve to realign the image if it falls outside the fovea, the area of…

Individuals with autism show a complex profile of differences in imitative ability, including a general deficit in precision of imitating another's actions and special difficulty in imitating nonmeaningful gestures relative to meaningful actions on objects. Given that they also show atypical patterns of visual attention when observing social…

In this article, the authors investigated unimodal and cross-modal processes in spatial working memory. A number of locations had to be memorized within visual or haptic matrices according to different experimental conditions known to be critical in accounting for the effects of perception on imagery. Results reveal that some characteristics of…

To coordinate our actions with those of others, it is crucial to not only choose an appropriate category of action but also to execute it at an appropriate timing. It is widely documented that people tend to unconsciously mimic others' behavior. The present study show that people also tend to modify their movement timing according to others'…

Two experiments investigated infants' ability to localize tactile sensations in peripersonal space. Infants aged 10 months (Experiment 1) and 6.5 months (Experiment 2) were presented with vibrotactile stimuli unpredictably to either hand while they adopted either a crossed- or uncrossed-hands posture. At 6.5 months, infants' responses were…

This study assessed the effects of a vibrating pager for increasing the duration of meal consumption in 3 teenagers with autism who were observed to eat too quickly. Participants were taught to take a bite only when the pager vibrated at predetermined intervals. A reversal design indicated that the vibrating pager successfully increased the total…

This study examined the use of technology by eighth grade students and teachers and perceptions of students and teachers toward technology use in the classroom and home. A mixed design method was selected to collect and analyze the data. Face-to-face interviews, field notes, and national survey results were used to triangulate the data. Three…

This dissertation reports the results of within-English structural priming experiments in language production which investigated the syntactic representations of English syntactic structures in three different bilingual groups: Japanese-English, Korean-English, and Mandarin Chinese-English bilinguals. Specifically, my dissertation research…

The ill-effect of noise on human performance has been studied by researchers in the fields of cognitive psychology and education for almost a decade. The learning theory Cognitive Information Processing was applied to a new empirical study that builds upon past relevant research on (a) working memory and individuals with learning disabilities, and…

Developmental dyscalculia (DD) is a deficit in number processing and arithmetic that affects 3-6% of schoolchildren. The goal of the present study was to analyze cerebral bases of DD related to symbolic number processing. Children with DD aged 9-11 years and matched children with no learning disability history were investigated using fMRI. The two…

From an information processing perspective, humans have a limited attentional capacity for processing information. Thus, second language (L2) researchers have investigated the role of pretask planning in task performance, finding that planning results in greater fluency and complexity but has mixed effects on accuracy. However, most planning…

Conversion disorder is characterized by neurological signs and symptoms related to an underlying psychological issue. Amygdala activity to affective stimuli is well characterized in healthy volunteers with greater amygdala activity to both negative and positive stimuli relative to neutral stimuli, and greater activity to negative relative to…

The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

Concept mapping is a technique used to provide a visual representation of an individual's ideas about a concept or set of related concepts. This paper describes a concept mapping tool using a photograph association technique (CoMPAT) that is considered to be a novel way of eliciting children's ideas. What children at 11 years of age know about…
