The primary interests of the Cognitive Information Processing Group are related to gaining an understanding of visual processes; in particular, to the ways by which humans can process pictorial information. Thus we do research on electronic methods for simplifying pictures (still or motion), without altering significantly human subjective judgments of picture quality, on methods for altering pi...

Smart sensors could be useful in a lot of applications for a speedy and rough vision. We describe in this paper an architecture of a SIMD mesh array optical sensor, we give an implementation in this architecture of the main loop of an algorithm of pseudo-euclidian skeletonization and we present an example of control programmation, a counter of binary pixels made with elementary projections. Whe...

In this work, the motion parameters of the bi-directionally predicted pictures (B-pictures) of MPEG-1,2 are exploited for concealment of large portions of corrupted anchor pictures that might arise due to channel errors or packet losses. To further enhance the quality of the concealed anchor pictures, we propose two methods of constraining the motion vectors of the B-pictures that strengthen th...

This paper describes LEFTY, a two-view graphics editor for pictures in various contexts. This editor has no hardwired knowledge about specific picture layouts or editing operations. A picture is described by a program containing functions to draw the picture and functions to perform editing operations appropriate to the specific picture. Primitive user actions, like mouse and keyboard events , ...

In Experiment 1 subjects studied a mixed list of pictures and words and then received either a free recall test or a word fragment completion test (e.g., _YL.mL for pyramid) on which some fragments corresponded to previously studied items. Free recall of pictures was better than that of words. However, words produced greater priming than did pictures on the fragment completion test, although a ...

The present study was carried out to examine the effect of movement and coloring of concomitant pictures on children's story learning. The story was Hans Christian Andersen's HINAGIKU (daisy), which was 47 sentences long. In relation to the story, the subjects in experimental groups were presented the static or moving pictures by means of picture-card show or animation video. Those pictures wer...

Arousal enhances memory in human participants and this enhancing effect is likely due to the release of peripheral epinephrine. As epinephrine does not readily enter the brain, one way that peripheral epinephrine may enhance memory is by increasing circulating blood glucose levels. The present study investigated the possibility that emotionally arousing color pictures would improve memory and e...

It remains unclear why individuals with autism spectrum disorder (ASD) tend to respond in an atypical manner in social situations. Investigating autonomic and subjective responses to social vs. nonsocial stimuli may help to reveal underlying mechanisms of these atypical responses. This study examined autonomic responses (skin conductance level and heart rate) and subjective responses to social ...

children with attention-deficit/hyperactivity disorder (adhd) react explosively and inappropriately to emotional stimuli. it could be hypothesized that these children have some impairment in attending to emotional cues. based on this hypothesis, we conducted this study to evaluate visual directions of children with adhd towards paired emotional scenes.thirty boys between the ages of 6 and 11 ye...
