This study sought to determine the effects of distinguishable learner perceptual modes on recall and retention of varying types of propositions presented in a television documentary. Particular focus was given to assessing learning across distinct levels of propositions differentiated by their contextual prominence in the audio channel and the degree of substantive support each received from the visual channel. / A systematic prose analysis scheme was used to decompose the narrative portion into main and subordinate ideas. The visual channel was then analyzed to classify the iconic display for each proposition as redundant, related or unrelated support. These analyses provided for the identification of six levels of presentation: main/redundant; subordinate/redundant; main/related; subordinate/related; main/unrelated; subordinate/unrelated. Eight propositions were randomly selected from each level to construct a recall test consisting of 48 items. / Participants included 99 young adults who were randomly assigned to one of four treatment groups: intentional/immediate; intentional/delayed; entertainment/immediate; entertainment/delayed. Entertainment and intentional learners were given different pre-treatment instructions in order to elicit the desired predisposed perceptual mode. After the treatment, each group was tested either immediately or following a seven day delay. / Using a series of ANOVAs and a subsequent Bonferroni adjustment, results indicated a significant main effect for recall interval across all subtests, except that representing the main/redundant level of presentation which failed to maintain significance under the Bonferroni adjustment. There was no main effect for perceptual mode at any level, although an interaction between mode and interval was detected at the subordinate/redundant level. / The inconsistencies found at the redundant levels of presentation, when compared to all other levels, suggest that perceptual mode may be a factor affecting recall when propositions are supported by redundant visuals. Moreover, additional evidence indicated that redundant propositions are recalled better than related or unrelated propositions, particularly at a delayed interval and for learners in an entertainment mode. / Source: Dissertation Abstracts International, Volume: 47-07, Section: A, page: 2552. / Thesis (Ph.D.)--The Florida State University, 1986.
