In recognition memory, anything that is objectively new is necessarily not-old, and anything that is objectively old is necessarily not-new. Therefore, judging whether a test item is new is logically equivalent to judging whether it is old, and conversely. Nevertheless, a series of 10 experiments showed that old? and new? judgments did not produce…

Recognition memory, defined by novelty preferences, was found to vary over 4 discrimination tasks as a function of length of familiarization for 5-6-month-old infants. (ST)

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)

Eight experiments using as Ss either retarded children, normal children, or normal adults studied the relations of retardation and normal development to the perceptual process of identification. Two experiments were reported on the identification of stimuli varying in either one, two, or three dimensions. Retardates did not perform as well as…

The effectiveness of three fading and two nonfading procedures were compared in training kindergarten children on an oddity problem in which shape was the relevant dimension. (SBT)

This data on transfer and list identification, combined with those reported by Petrich et al. (1975), strongly suggest that the decision component is the major factor affecting the free recall of successive overlapping lists. This decision component is best described by Anderson and Bower's model (1972) of the roles of list tagging and contextual…

Two studies of 7-year-olds and college students tested the hypothesis of a developmental difference in the degree to which subjects' memory performance was controlled by categorical properties vs. specific instance properties of test items. (GO)

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)

Results of research presented at the meeting of the Eastern Psychological Association, New York, New York, April 1970. (VM)

The present study was aimed at simultaneously determining on the same subject, the effects of stress on retrieval of flexible (contextual or temporal) or stable (spatial) information. Three behavioral paradigms carried out in a four-hole board were designed as follows: (1) Simple Discrimination (SD), in which mice learned a single discrimination;…
