Three experiments examined 4- to 10-month-olds' perception of audio-visual (A-V) temporal synchrony cues in the presence or absence of rhythmic pattern cues. Results established that infants of all ages could discriminate between two different audio-visual rhythmic events. Only 10-month-olds detected a desynchronization of the auditory and visual…

Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

This experiment assesses spatial and nonspatial relational memory in freely moving 9-mo-old and adult (11-13-yr-old) macaque monkeys ("Macaca mulatta"). We tested the use of proximal landmarks, two different objects placed at the center of an open-field arena, as conditional cues allowing monkeys to predict the location of food rewards hidden in…

A total of 128 first- and second-graders participated in two sets of shift problems: (1) four extra-dimensional shifts; and (2) shift problems with two types of cue-reinforcement conditions (same and reversal). (ED)

Groups trained to compare the whole and subset improved in cue identification from negative instances; performance in the stimulus exposure group declined. (Authors)

Alternative analysis to study reported in PS 502 061. Rejoinder presented in PS 502 063. (MB)

This case study describes initially unsuccessful attempts to use the delayed-cue procedure to teach conditional discriminations to a 25-year-old male with moderate mental retardation. The subject typically waited for the delayed cue unless differential responses to the dictated samples (repeating the sample names) were required. (Author/DB)

Experiment I was designed to demonstrate that young children fail to abstract the positive cue as the relevant stimulus event in a restricted concept-learning task. Sixteen kindergarten and 16 fourth grade subjects were trained to criterion on a Kendler-type task, whereupon each subject was presented a pair of new instances which contrasted only…

The purposes of this study were to assess the effect of phoneme-grapheme consistency (PGC) and cue emphasis (CE) on the development of decoding skills in first graders and to determine the relationship of consistency of original lists to the recognition of new words. Subjects were 162 first graders, mean age 6.11 years and scoring above 30 on the…
