Word Fragment Completion Task Research Articles

Priming is independent of skill learning.

This study examined the relation between repetition priming and skill learning. Priming refers to facilitation in processing a specific item as a result of previous exposure to that item. Skill learning refers to general improvement in task performance as a function of practice. In Experiment 1 (N = 60), skill acquisition occurred in partial-word identification and inverted reading tasks but not in a word-fragment completion task. However, the amount of priming was the same in all three tasks. In Experiment 2 (N = 52), priming effects in partial-word identification did not vary as a function of practice with degraded words. In Experiment 3 (N = 40), skill learning was greater with high- than with low-frequency words, whereas priming was unaffected by word frequency. Experiment 4 (N = 20) ruled out the possibility that explicit retrieval was involved in the implicit memory tasks. These results suggest that priming can be independent of skill learning.

Item effects in recognition and fragment completion: Contingency relations vary for different subsets of words.

Item effects were examined in recognition-memory and word-fragment completion task, using the 192 words and fragments from Tulving, Schachter, and Stark (1982). Independant variables included various subjective ratings taken on the words and various quantitative characteristics of the word fragments.

Effects of varying modality, surface features, and retention interval on priming in word-fragment completion.

Subjects in Experiment i studied a list of words under varying presentation conditions (visual or auditory) and in two typographies within the visual condition (typed or hand printed) and then received a word-fragment completion test (e.g., —YS—E—Y formystery) in which the test cues also varied in typography. The main findings were that (1) priming occurred for all study items, relative to nonstudied items, but greater priming occurred for visual than for auditory presentation, and (2) performance in the visual conditions was better when typographies matched between study and test than when the typographies mismatched, but only for words studied in hand-printed form. These findings were generally replicated when the test was delayed 1 week, although priming declined across this retention interval (Experiment 2). In Experiment 3 subjects studied words that were either in focus or blurred and showed greater priming when test fragments were presented in the same manner as at study. Priming in the word-fragment completion task depends on matching surface characteristics of items between study and test and exemplifies the requirement of performing similar mental operations at study and test for maximizing performance (transfer-appropriate processing).
