Two experiments were conducted to evaluate the relative efficiency of verbal (questions) and visual (directions to sketch) adjunct aids for concrete and abstract prose learning. Results for the concrete passage did not confirm earlier work by the authors demonstrat ing equivalency for two types of aids. For the abstract passage, verbal adjunct aids worked best and visual aids were somewhat disruptive. Implications are discussed. SNOWMAN AND CUNNINGHAM (8) recently compared verbal and visual adjunct aids and found that with a fairly concrete passage they operated equivalently. In that study the verbal adjunct aids were multiple choice questions interspersed in the text in a manner similar to that found in most adjunct aid studies (7). Visual adjunct aids were developed by interspersing directions to sketch pictures, the directions being derived from the item stem of the corresponding multiple-choice question. For instance, the following two adjunct aids were used in the Snowman and Cunningham (8) study: Verbal With what do the Gruanda pay their taxes? a. animal skins b. wheat and beets c. colored beads d. colored stone disks Visual Sketch a picture depicting with what the Gruanda pay their taxes. The standard finding in most questioning studies was replicated for verbal questions and extended to visual adjunct aids. Thus, the insertion of questions or direc tions to sketch resulted in increased retention of material directly covered by those adjunct aids (practiced retention) as compared to a control group. In addition, when these adjunct aids were inserted just after the por tion of the text to which they referred, retention of material not directly covered by these aids (nonpracticed retention) was improved as compared to when these aids appeared before the relevant text passage. 8 This content downloaded from 157.55.39.111 on Tue, 02 Aug 2016 04:11:26 UTC All use subject to http://about.jstor.org/terms CUNNINGHAM, SNOWMAN, MILLER, AND PERRY 9 In discussing their results, Snowman and Cunning ham (8) speculated that different results might have oc curred if the instructional passage had not been con crete. The present study is designed to examine this possibility. The earlier study was repeated to test the reliability of its findings and, in addition, a second ex periment was conducted concurrently in which an abstract version derived from the concrete passage was employed. Since the abstract version differed in content from the concrete passage, a new criterion test was con structed for the abstract passage, necessitating treating the research as two concurrent experiments rather than as a single experiment. The hypotheses to be tested for the concrete passage are identical to those proposed by Snowman and Cunningham (8). Our predictions concerning the abstract passage were derived from the theoretical posi tion of Paivio (6), who argues that imagery facilitates the recall of concrete content but not abstract content. He has found that verbal mediators are more facilitative with abstract material. It was, therefore, expected that with a more abstract passage, verbal adjunct aids would prove more effective than visual ones; that is, the usual question position effect with practiced and nonpracticed retention would be observed only with verbal questions. Further, it was felt that visual adjunct aids would be disruptive as compared to controls reading without ad junct aids.
