Incentives produced no discernible effect upon the performance of either of two treatment groups. The data were also analyzed for latency of response, practice effects and reversal errors, none of which was related to reading retardation. (WY)

Special microcomputer systems that provide data entry by voice can be an important development for the disabled. The Shadow/VET (voice entry terminal) is a computer voice entry product with reasonable cost/performance that is being marketed by Scott Instruments. (SEW)

Results from testing 20 first graders in a remedial class in Maryland indicated that: same pattern recognition was significantly higher than reverse pattern recognition; identical pattern recognition did not affect performance on reading and arithmetic achievement; reverse pattern recognition significantly affected performance on reading and…

In three experiments, this study addressed two basic questions about the detection of multiletter patterns: (1) How is the detection of a multiletter pattern related to the detection of its individual components? (2) How is the detection of a sequence of letters influenced by the observer's familiarity with that sequence? (Author/BW)

Adults listened to a list containing 30 words that were repeated from zero to seven times each. Subjects were tested for sensitivity to differences in frequency of occurrence. All were equally sensitive to frequency information. Prior knowledge about the nature of the test did not affect performance. (Author)

Three experiments examined whether the perception and retention of feature relations, thought to be critical for object recognition in adults, are evident in early infancy. Three month olds' 24-hour retention was disrupted when features of a 6-item mobile were recombined, indicating that they not only encode feature relations but also remember…

Examined developmental change and stability of visual expectation and reaction times among 5-, 7-, and 12-month-old term and preterm infants. Found that reaction times declined with age while anticipations increased. Infants with faster reaction times were more likely to anticipate upcoming events; this effect disappeared when time between stimuli…

In a recent edition of "Mathematics Teaching" Midge Pasternack argued the case for the use of the 0-99 square with young children rather than the ubiquitous 1-100 square. In this article, the author would like to take the opportunity to mount a defence in favour of the much maligned 1-100 square. His main criticism of the 0-99 square (apart from…

This paper analyzes geographic patterns of population concentration and deconcentration among the foreign-born population during the 1990-2000 period. A goal is to examine whether the foreign-born population, including recent arrivals, are dispersing geographically from metro gateway cities into rural and other less densely populated parts of the…

This paper is concerned with the use of spreadsheets within mathematical investigational tasks. Considering the learning of both children and pre-service teaching students, it examines how mathematical phenomena can be seen as a function of the pedagogical media through which they are encountered. In particular, it shows how pedagogical apparatus…

The books in this series provide an essential ingredient in the transition from concrete mathematical experience to the symbolic reasoning used in algebra. They aim to guide the student in building and extending manipulative patterns, collecting numerical data, and analyzing the results. The main objective of the activities in this book is for the…

This paper presents evidence that four design principles commonly embodied in artificial knowledge systems are inconsistent with human cognitive capabilities. Because these principles are widely accepted as characteristics of human knowledge processing, common theoretical properties related to cognitive psychology and artificial intelligence which…

A method of summing finite sequences by use of formal power series techniques is described. (SD)
