The ability of preschool children to construct and reconstruct ordered sequences was examined in a series of four experiments. Subjects were 42 children aged 3 to 5 years. The conditions under which reconstruction of an arbitrary series of events is possible are described. (Author/GO)

Preschool to fourth grade subjects were required to reconstruct a previously seen logical sequence by selecting old items from a set containing actually seen events. Older children were found to be more consistent in all task performances. (DEP)

This study examined mental age differences in the ability of educable retarded children to predict their recognition accuracy when recall failed. Results are discussed in terms of the complexity of the metamemory judgment required. (Author/JMB)

Preschoolers' recall and clustering of organized lists of pictures were examined either under deliberate instructions to remember or in incidental learning situations. It was concluded that the activity of the children determines depth of processing and subsequent retention, not the intent to remember. (JMB)

Recent studies have offered support for a constructive view of sentence memory in children, based on their preference in recognition errors for true inferences, which can be drawn from input sentences, over false inferences. However, with the materials used in these studies, this preference may reflect responding either on the basis of semantic or…

Training in memory span-estimation for two age groups of educable mentally retarded children was administered to assess whether such training could lead to long-term improvement in the younger children's knowledge concerning their memory limitations. (SB)

Memory-based searching was compared in 15 developmentally delayed and 24 normal two-year-olds. In a relatively easy memory task, individual differences were minimal, but searching for a plausible alternative location based on memory revealed marked individual differences and an important difference in the cognitive functioning of the delayed…

Reports the findings of a series of long-term maintenance tests and a generalization phase given to a group of educable mentally retarded children more than one year after they were trained to use self-checking routines for estimating test readiness. (JMB)

Two studies (1) compared the ability of pre- and post-operational children to seriate sets of 4 temporal sequences presented simultaneously and (2) examined the ability to recall sequences when given the initial, middle, or terminal item as a retrieval cue. (SB)

The first section of this report examines, from a developmental perspective, the major theoretical positions dominating the literature on adult cognition. Two criteria are considered. First, how compatible are the theories with the notion that thinking systems develop within specific environments? Second, what are the implicit or explicit…

The present study was designed to test the implication of the rehearsal deficit hypothesis of Brown (1972) and Morin et al. (1970). In it retarded adolescents were given rehearsal training on a keeping-track task. (Author/RK)

The first section of this report reviews traditional memory studies, which have provided much of our information concerning memory development. Major strengths and weaknesses of memory-development studies are illustrated by comparison with recent research into children's problem-solving skills. The report concentrates on one area of general…
