Abstract:
6 24-word English sentences were made up, 2 representing each of 3 levels of meaningfulness. Meaningfulness was defined in terms of the Thorndike-Lorge frequency of the words making up the sentences. The sentences were mounted on memory drums and learned by serial anticipation to a criterion of 100% correct responses or to a lower criterion, equivalent across level of meaningfulness. The retention intervals were 20 min. and 24 hr., the former providing a control for post-criterial drop. The measure of retention was the number of items lost during the interval. The main effects for both retention interval and meaningfulness were significant as was the interaction term between level of learning and retention interval. Because there were no significant interaction terms involving meaningfulness, it was concluded that the main effect for meaningfulness was an artifact resulting from differing degrees of associative strength at the end of learning. This conclusion was reinforced by scrutiny of 24-hr. loss scores, corrected for post-criterial drop.
