Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)

If the N1 wave (amplitude component between 80-130 msec) does not serve as an index of an initial stimulus set stage of selection, the N1 amplitudes should be differentiated between channels whether the selection is based on pitch, spatial position, intensity, or cues that lead to an efficient rejection of unwanted information. This study…

The effects of real-world schemata on recognition of complex pictures were studied. Two kinds of pictures were used: pictures of objects forming real-world scenes and unorganized collections of the same objects. (Editor)

This research sought to distinguish among three concepts of visual persistence by substituting the physical presence of the target stimulus while simultaneously inhibiting the formation of a persisting representation. Reportability of information about the stimuli was compared to a condition in which visual persistence was allowed to fully develop…

The message we can get from McLuhan is to use the visual communication that conveys its own message, as in the case of advertising arts. (HOD)

Graphs, bars, charts, and diagrams have been used by designers, writers, and scientists to communicate. Now, research suggests that graphic organizers benefit teaching and learning. This article describes graphic organizers: sequential, conceptual, hierarchical, cyclical, Venn, fishbone or Ishikawa, squeeze and stretch, why-why, t-chart, KWL…

Summarizes state-of-the-art approaches for assessing visual stimulus same/different judgments in individuals with severe intellectual disabilities. Methodological investigations indicate that one can obtain reliable same/different judgments with a variety of stimuli in virtually anyone for whom a basal score on the Peabody Picture Vocabulary Test…

A study of 2 boys (ages 11 and 16) with mental retardation and destructive behaviors investigated whether alternative stimuli identified through a choice assessment would substitute for attention in a noncontingent reinforcement procedure. Both continuous noncontingent access to attention and to the identified tangible item reduced destructive…

Describes a new paradigm that may be appropriate for uncovering speech perceptual codes. Illusory words are detected by blending two dichotic stimuli. The paradigm's design allows for comparison of different speech units by the manipulation of the distribution of information between two inputs. (23 references) (Author/CK)

This article suggests ways to use tactile teaching strategies with students who have severe and multiple disabilities including blindness. Guidelines address tactile modeling, tactile mutual attention, presenting tactile information, providing effective tactile representation, hypersensitivity to touch, and a team approach. (Contains references.)…

Presents evidence that although patients with semantic deficits can sometimes show good performance on tests or object decisions, this pattern applies when nonsee-objects do not respect the regularities of the domain. Patients with semantic dementia viewed line drawings of a real and chimeric animals side-by-side and were asked to decide which was…

Used pictorial stimuli to test for revelation effect with 4- and 8-year-olds and adults. Found reliable revelation effect at all ages, indicating the complex fluency-of-processing discrepancy detection and attribution mechanisms thought to be responsible for the effect function similarly from 4 years through adulthood. Found recognition decisions…

Two studies examined 9- to 15-month-olds' ability to deduce an abstract nonmatching rule from reward feedback. Results showed that physical connectedness between stimuli and reward was key to performance. In the absence of the perception that stimulus and reward were components of a single thing, even close spatial and temporal proximity were…

Advances the idea that storyboarding, long associated with scriptwriting, advertising, and more recently with technical manuals, can be successfully applied to an even broader variety of technical documents. Applies storyboarding techniques to designing technical proposals to suggest methods of incorporating more visuals into documents, as well as…
