Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern. (HOD)

To demonstrate a relationship between rate of habituation and complexity levels, 11-week-old infants (N=51) were each given a rate-of-habituation and complexity-level test. Rapid habituators looked longer at complex patterns. Irregular habituators responded randomly to tests or resembled slow habituators in terms of complexity preferred. (ST)

The present study tested the feasibility of using a purely verbal recognition-memory procedure with young children and examined the role of verbal associations in the memory encoding of such children. (Author)

Clarifies some of the conditions under which verbal processes facilitate or inhibit learning of visual stimuli. (Author/AJ)

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…
