Working Memory In Schizophrenics And Older Adults : A Mediator For Episodic Memory Deficits?, Matthew W. Webster
Working Memory In Schizophrenics And Older Adults : A Mediator For Episodic Memory Deficits?, Matthew W. Webster
Master's Theses
The purpose of this study was to determine the role of working memory on episodic memory in older adults and adults with schizophrenia. This study included 15 adults with schizophrenia, 20 young adults without psychopathology, and 21 older adults without psychopathology. Storage working memory scores were greater than processing working memory scores in all groups. Young adults had the fewest problems with episodic and working memory, compared to older adults and adults with schizophrenia, who had similar deficits in both memory types. Speed of processing was found to be the greatest predictor of working memory capacity.

Educational Ability, Practice And Short Term Memory, Barbara Jean Arthur
Master's Theses
Thirty-six fourth grade students were selected and classified into one of three groups on the basis of participation in the DISTAR Reading Program, educational ability as measured by the STEA and a reading readiness factor, Each group received two tests of short term memory (STM ) involving auditory presentation and either auditory or visual recall after a retention interval of 4, 8 or 12 seconds. Analysis verified previous research in this area with respect of task difficulty, retention as a function of interval length and acoustic similarity of response errors. Neither educational ability nor practice elevated the students' performance on …

The Effects Upon Short-Term Memory Of Acoustic Interference And The Cognitive Separation Of A Reduntant Element, Robert A. Smallwood
Master's Theses
Sperling (1963) noted that some subjects (Ss) stated they could "hear" material being held in short-term storage, and he suggested that short_term memory (STM) for verbal materials may be in the form of an auditory loop. The first major laboratory investigations of this topic were made by Conrad (1962;1964) who examined the errors made in immediate recall, and found that substitution errors tend to involve units that sound alike (acoustically-similar), even when the original stimuli were visual. He concluded that visual letters are recorded into auditory representations, which may subsequently be confused with one author. The auditory, or at least …
