Recent empirical and theoretical work suggests that visual features such as color and orientation can be stored or retrieved independently in visual working memory (VWM), even in cases when they belong to the same object. Yet it remains unclear whether different feature dimensions have their own capacity limits, or whether they compete for shared…

Although superior visual search skills have been repeatedly reported for individuals with autism spectrum disorder, the underlying mechanisms remain controversial. To specify the locus where individuals with autism spectrum disorder excel in visual search, we compared the performance of autism spectrum disorder adults and healthy controls in…

Visual word N170 is an index of perceptual expertise for visual words across different writing systems. Recent developmental studies have shown the early emergence of visual word N170 and its close association with individual's reading ability. In the current study, we investigated whether fine-tuning N170 for Chinese characters could emerge after…

The day-night paradigm, where children respond to a pair of pictures with opposite labels for a series of trials, is a widely used measure of interference control. Recent research has shown that a happy-sad variant of the day-night task was significantly more difficult than the standard day-night task. The present research examined whether the…

Extensive research has focused on face recognition, and much is known about this topic. However, much of this work seems to be based on an assumption that faces are the most important aspect of person recognition. Here we test this assumption in two experiments. We show that when viewers are forced to choose, they "do" use the face more than the…

The "body inversion effect" refers to superior recognition of upright than inverted images of the human body and indicates typical configural processing. Previous research by Reed et al. using static images of the human body shows that people with autism fail to demonstrate this effect. Using a novel task in which adults, adolescents…

Models for multidimensional scaling use metric spaces with additive difference metrics. Two important properties of additive difference metrics are decomposability and intradimensional subtractivity. A prediction was derived from these properties and tested experimentally. Eleven non-psychology students were used as subjects. Rectangles varying in…

Two experiments were conducted to investigate the effects of multimodal information on learning performance and judgment of learning (JOL). Experiment 1 examined the effects of representation type (word-only versus word-plus-picture) and presentation channel (visual-only versus visual-plus-auditory) on recall and immediate-JOL in fixed-rate…

The purpose of this study was to evaluate the effects of sequential visual-motor skills, developed as described in "Visual Motor Development" (VMD), on the reading achievement of children enrolled in a remedial reading program in a San Antonio elementary school. Data were obtained from 52 children in first through sixth grades divided…

The purpose of the study reported in this paper was to examine the effect of visuals possessing different amounts of realistic detail and the effects of integrating covert and overt rehearsal strategies into visually complemented prose instruction. A total of 128 university students participated in the study, which involved a prose text on the…

The metacognitive performance of four groups of students was examined. The students' processes of visual analysis and discrimination of real-life pictures were used to measure metacognition. There were 61 participants: 18 hearing students, 18 deaf and hard of hearing students, 16 students with mild mental disabilities, and 9 students with physical…

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

The focus of this study was on the relationship between visual and statistical analyses of time series data and the degree to which characteristics of the data influenced this relationship. A total of 52 teachers took part in evaluating a series of graphs having prespecified characteristics. The independent variables manipulated included: slope,…

This report describes an experiment concerned with a possible relationship between the inability to learn basic educational skills, such as reading and writing, and the inability to organize incoming stimuli for communication purposes, in spite of adequate intellectual potential. The study had three main tasks. The first problem was to develop a…

Thirty-five second-grade learning disabled children participated in a visual information processing training program designed to teach analysis of visual material into component parts, systematic scanning of visual arrays, pick-up, description, and memory storage of distinctive information, and efficient solution of visual match-to-sample…
