RESEARCH
Effects of Retrieval Practice on Cognitive Categorization and Subsequent Elaborative Processing of Verbal-Spatial Memory
The research explored if integrated verbal-spatial associations in working memory impact hierarchical organization in cognitive processes and knowledge construction activities among young adult learners. Three types of exposure (verbal/spatial/verbal-spatial) and rehearsal strategies (overt retrieval/covert retrieval/restudy) were used. Verbatim recall was better in covert retrieval and restudy groups than overt retrieval with verbal-spatial exposure. For complex tasks of creating hierarchical categories among exposed items, covert and restudy groups with verbal-spatial exposure outperformed the overt retrieval group. Importantly, in the covert retrieval and restudy groups, conscious awareness and restudying, respectively, combined with attention-demanding verbal-spatial exposure, led to richer item connections, enhancing syntactic processing, coherence, and global elaborative processing in learning tasks.
Some specific questions include:
- Do exposure type (verbal/visuospatial/verbal-spatial) and rehearsal strategies (overt/covert/restudy) can induce any effects on factual knowledge-induced verbatim recall of exposed materials?
- Do exposure type (verbal/visuospatial/verbal-spatial) and rehearsal strategies (overt/covert/restudy) have any influence in creating hierarchical categories of learning stimuli?
- Do exposure type and rehearsal strategies can create any variations in syntactic processing and coherence while forming applicability-based proses induced from factual knowledge-induced hierarchically categorized words?
- Do exposure type and rehearsal strategies influence the applicability of factual knowledge reflected through global elaborative processing (i.e., combination of recall, categorization, syntax, and coherence) of exposed materials?
