We tested the effects of orthography on text reading by comparing reading measures in Arabic and Hebrew-speaking adults. The languages are typologically very similar, but use different orthographies. We measured naming speed of single letters, words and nonwords, and visual processing. Arabic-speakers also performed some of the tasks in Hebrew. We…

Despite the importance of handwriting for school readiness and early academic progress, prior research on the development of handwriting has focused primarily on the product rather than the process by which young children write letters. In contrast, in the present work, early handwriting is viewed as involving a suite of perceptual, motor, and…

The present study examined whether individuals with autism spectrum disorder (ASD) are able to update and monitor working memory representations of visual input, and whether performance is influenced by stimulus and task complexity. 15 high-functioning adults with ASD and 15 controls were asked to allocate either elements of abstract figures or…

Predictions from perceptual load theory (Lavie, 1995, 2005) regarding object recognition across the same or different viewpoints were tested. Results showed that high perceptual load reduces distracter recognition levels despite always presenting distracter objects from the same view. They also showed that the levels of distracter recognition were…

These proceedings contain the papers of the 16th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2019), held during November 7-9, 2019, which has been organized by the International Association for Development of the Information Society (IADIS) and co-organised by University Degli Studi di Cagliari, Italy.…

The study examined the possible existence of a perceptual hierarchy which is systematically affected by the onset of adventitious visual impairment. Results with 80 persons with partial vision indicated a demarcation of difficulty between the simpler and more complex levels of the hierarchy. (DB)

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…

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)
