ROLE OF ASSOCIATIVITY IN THE DEVELOPMENT OF STRATEGIC ORGANIZATION IN CHILDREN'S MEMORY

Abstract/Description
Cognitive theorists hypothesize two types of cognitive processes (e.g., automatic and effortful) which may influence human information processing. This thesis investigates age differences in when children use intralist associative relationships (thought to be automatic in nature) to identify other (categorical) relations. Use of conceptual/ categorical relations to organize recall is thought to be effortful in nature. Sixty children each from grades 3, 5, 7, and 9 were presented orally with...
Show moreCognitive theorists hypothesize two types of cognitive processes (e.g., automatic and effortful) which may influence human information processing. This thesis investigates age differences in when children use intralist associative relationships (thought to be automatic in nature) to identify other (categorical) relations. Use of conceptual/ categorical relations to organize recall is thought to be effortful in nature. Sixty children each from grades 3, 5, 7, and 9 were presented orally with lists of 20 words under free-recall instructions. Results provide support for the position that recall memory of young children is mediated primarily by associative rather than conceptual relationships. Also, partial support was obtained for the three stage model of the development of organization proposed by Bjorklund and Zeman (1982). However, the model's prediction of when children will optimally use associative relationships to identify categorized relations was inaccurate. These results indicate that older childrens' recall can be facilitated by automatic cognitive processes resulting in higher levels of clustering (organization) and recall.

Hippocampal CA1 activation during object memory encoding in the novel object recognition task
Title
Hippocampal CA1 activation during object memory encoding in the novel object recognition task.

Abstract/Description
Transcription and translation of proteins are required for the consolidation of episodic memory. Arc, an effector immediate early gene, has been linked to synaptic plasticity following learning and memory. It is well established that the rodent hippocampus is essential for processing spatial memory, but its role in processing object memory is a point of contention. Using immunohistochemical techniques, hippocampal sections were stained for arc proteins in the CA1 region of the dorsal...
Show moreTranscription and translation of proteins are required for the consolidation of episodic memory. Arc, an effector immediate early gene, has been linked to synaptic plasticity following learning and memory. It is well established that the rodent hippocampus is essential for processing spatial memory, but its role in processing object memory is a point of contention. Using immunohistochemical techniques, hippocampal sections were stained for arc proteins in the CA1 region of the dorsal hippocampus in mice following two variations of the novel object recognition (NOR) task. Results suggest mice that acquired strong object memory showed significant hippocampal activation. In mice that acquired weak object memory, hippocampal activation was not significantly different from controls. Arc expression was also examined in other hippocampal sub-regions, as well as in the perirhinal cortex. These results suggest that the mice must acquire a threshold amount of object information before the hippocampal CA1 region is engaged.
