The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

This article reported the development of a method aimed at exploring the relations among covert muscle behavior, mental imagery, and the perception of external stimulation. (Author/RK)

The theory is developed and contrasted with other theories of pattern recognition in which concepts such as stimulus generalization, tuned detectors, and preprocessing play major roles. A relation of this theory to problems encountered among disabled readers ("dyslexics") is also brought out. (Author/BJG)

Thirty learning disabled and thirty nondisabled children (mean age 10 years) were compared on a paired associate learning task that simulated the process of sight word learning. Two instructional variables (response competition and stimulus complexity) that have been hypothesized as contributing to overloading in learning disabled children, were…

In a visual recognition masking experiment, a target stimulus to be identified is either preceded or followed by a second stimulus called a masking stimulus. The experiments described here provide estimates of both developmental and aging differences in visual backward masking under conditions which maximize interference in the central visual…

This bibliography lists 260 articles reporting on research in which the use of pictures as experimental stimuli is central to (not incidental to) the researcher's hypotheses and in which internal imaginal processes are presumed to be activated, no matter what the nature of the experimental stimuli. The articles included are from the 1980 issues of…

Three experiments were performed in which subjects were exposed to two sizes of the Embedded Figures Test (EFT), and subjects in the third experiment were also exposed to two sizes of the Rod and Frame Test (RFT). In the first experiment, where the EFT had a size differential of 1 to 4, a nonsignificant size effect and a significant rank…

The perception of duration in consonant segments is compared with their produced durations, and adults' and children's performance in this respect are compared. The temporal organization imposed by adults on initial consonant clusters was often not imposed by children from four to eight years of age, even though the cluster was produced…

The cooperative Navy/Air Force project described is aimed at the problem of image-flutter encountered when visual displays that present computer generated images are used for the simulation of certain flying situations. Two experiments are described which extend laboratory work on delay compensation schemes to the simulation of formation flight in…

Perhaps due to misunderstandings of the nature of the research task in visual communication, findings of empirical research in that field have been highly inconsistent. Historically, there has been little serious systematic empirical investigation of visual communication. One difficulty is that it is not always possible to measure nonverbal…
