Abstract:
Working memory is the ability to simultaneously process and store information (Baddeley, 1986). Complex span tasks, such as reading span, are a widely used paradigm to investigate working memory recall (Daneman & Carpenter, 1980). This thesis presents six experiments that investigate processing and memory relationships in children and adults complex span performance. Experiments 1 to 3 found processing speed significantly influences children's recall in a reading, operation and listening; span task. Evidence is provided for a developmental shift in the importance of processing speed in reading span performance between aged 8- to 14-years-old. However, processing speed is shown to be less important for adults 11' retention in complex span tasks. Furthermore, profiles in the relationship between processing speed and memory are demonstrated to differ according to the type of complex span task, and the relationship between the content of processing and memory. The relationship between the content of processing and memory, influences both children's and adults recall in a complex span task. Memoranda items integrated to the processed element (for example retention of the final word of the processed sentence) are subject to enhanced recall over items independent to the processing. This is demonstrated to be superior in a lexical based span task (reading span) over a non-lexical based span task (operation span). However, mixed evidence is provided in Experiments 2 and 3 for enhanced recall under circumstances in which the memoranda items are semantically associated to the processing. Experiments 4, 5 and 6 investigate the role of pro active interference in complex span task performance. A build up and release of PI is demonstrated in an operation span task, highlighting that inhibition of interference is likely to be a further important factor in complex span task performance.
