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…

Studies the allocation of attention of 100 four- and five-year-olds on a selective attention task. Results suggest that preschoolers are capable of using selective strategies when the task is made meaningful by the inclusion of a familiar script that provides supportive cognitive context. (RJC)

Twelve moderately retarded children were trained on 2-choice visual discrimination problems with interpolation of another item between training and retention tests. Results indicated that well-learned items are rehearsed less. (SBT)

A total of 630 boys and girls from kindergarten to second grade were asked to compare durations that differ in beginning times with those that differ in ending times. Possible sources of children's failure to integrate beginning and end points when comparing durations were discussed. (Author/CI)

The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…

This experiment examines extended learning over a 4-day period in infants exposed to responsive and unresponsive wooden mobiles. Frequency of kicks and attention to the mobile increased over the first three days and was found to vary with the introduction of a novel mobile on day four. (GO)

Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

Two experiments examine the sorts of cues that might be available to facilitate children's ability to discriminate between memories for their own actions. Results suggest that the differences in discrimination performance demonstrate the importance of kinesthetic cues and visible consequences for children's memory discrimination. (Author/RWB)

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. (Editor)
