Yijun Ge – ProQuest LLC, 2021
Our visual system samples external information, adjusts its sensitivity and constructs a stable representation of the world that allows us to perceive and interact with objects in our environments. Visual information with different levels of complexity is processed through the hierarchically organized visual cortical areas. This dissertation…

Sen, Ayon; Patel, Purav; Rau, Martina A.; Mason, Blake; Nowak, Robert; Rogers, Timothy T.; Zhu, Xiaojin – International Educational Data Mining Society, 2018
In STEM domains, students are expected to acquire domain knowledge from visual representations that they may not yet be able to interpret. Such learning requires perceptual fluency: the ability to intuitively and rapidly see which concepts visuals show and to translate among multiple visuals. Instructional problems that engage students in…

Bartolucci, Marco; Smith, Andrew T. – Neuropsychologia, 2011
Practicing a visual task commonly results in improved performance. Often the improvement does not transfer well to a new retinal location, suggesting that it is mediated by changes occurring in early visual cortex, and indeed neuroimaging and neurophysiological studies both demonstrate that perceptual learning is associated with altered activity…

Redford, Joshua S. – Psychological Record, 2010
Recently, Redford (2010) found that monkeys seemed to exert metacognitive control in a category-learning paradigm. Specifically, they selected more trials to view as the difficulty of the category-learning task increased. However, category-learning difficulty was determined by manipulating the family resemblance across the to-be-learned exemplars.…

Colonnesi, Cristina; Koops, Willem; Meerum Terwogt, Mark – Infant and Child Development, 2008
The present study examined two key aspects of young children's ability to explain human behaviour in a mentalistic way. First, we explored desires that are of a level of difficulty comparable with that of false beliefs. For this purpose, the so-called "alternative desires" were created. Second, we examined how children's psychological…

Weizmann, Fredric; And Others – 1979
The primary purpose of this study was to examine whether a general perceptual model developed by Vitz and Todd (1971), capable of dealing with multiple determinants of attending, is useful for understanding infant attending. The model, previously used in research with adults, assumes that perception can be represented as a stochastic sampling…

McWhinnie, Harold J. – California Journal of Educational Research, 1970
Investigates effects of a specific method of art instruction designed to increase the individual's ability to handle visual complexity and detail. Implications of findings for art education are also discussed. ( MG)

Kraus, Marcy L. – 1984
The effects of age, task, and egocentric responding on visual-spatial perspective taking were studied among 41 preschool children between 3.0 and 5.9 years of age. Children were individually administered three perspective-taking measures: the upside-down/right-side-up task, a block task, and a picture box task, all previously described in the…

Brown, Donald R.; Ottinger, D. R. – 1970
Four studies with infants and preschool-age children examined various pattern perception tasks considered to be related to the perceptual basis of the development of reading skills. Study 1 used 28 neonates to test the hypothesis that supplemental stimulation (rocking, patting, holding) has measurable effects upon attention to visual patterns.…

Jager, Stephan; Wilkening, Friedrich – Journal of Experimental Child Psychology, 2001
Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

Chromiak, Walter; Weisberg, Robert W. – Journal of Experimental Child Psychology, 1981
Adults' ability to track a moving target was examined in two experiments in order to compare their performance with that of very young infants. Results indicated that (1) adults'"overshoot" errors resembled those reported for young infants; and (2) adults had problems tracking a moving target which unexpectedly changed direction. (Author/DB)

Davidson, Philip W.; And Others – 1979
This experiment compared retarded and normal subjects at different developmental levels on visual (V) and haptic (H) matching tasks. Systematic observations of variables known to have developmentally linked effects on accuracy, including stimulus complexity and haptic exploratory search style, were made. Seventeen mentally retarded subjects, with…
