Lexical Decision as an Indirect Test of Memory: Repetition Priming and List-Wide Priming as a Function of Type of Encoding
نویسنده
چکیده
Two experiments examined priming in the lexical decision task, an indirect test of memory. Experiment 1 manipulated type of processing during study of unrelated word pairs. Recognition of individual words benefited more from semantic than from nonsemantic processing. Repetition priming in lexical decision depended on the context in which the target appeared. Targets preceded at test by unstudied primes showed greater repetition priming if processed nonsemantically during study; targets preceded at test by studied primes were not affected by type of processing at study. Interestingly, studied targets were facilitated more by studied than by unstudied primes regardless of whether the prime came from the same pair as the target. This list-wide episodic priming occurred under all four processing conditions in Experiment 1 (consonant counting, rote rehearsal, pleasantness rating, and sentence generation) with a 250-ms stimulus onset asynchrony. Experiment 2 showed that this list-wide episodic priming disappeared by 1,000 ms, suggesting that it had resulted from relatively transient activation.

Repetition priming across distinct contexts: effects of lexical status, word frequency, and retrieval test.
Repetition priming, the facilitation observed when a target is preceded by an identity prime, is a robust phenomenon that occurs across a variety of conditions. Oliphant (1983), however, failed to observe repetition priming for targets embedded in the instructions to an experiment in a subsequent lexical decision task. In the present experiments, we examined the roles of priming context (list o...
متن کاملLevels of processing and selective attention effects on encoding in memory.
The purpose of the present study was to investigate the effects of selective attention and levels of processing (LOPs) at study on long-term repetition priming vis-a-vis their effects on explicit recognition. In a series of three experiments we found parallel effects of LOP and attention on long-term repetition priming and recognition performance when the manipulation of these factors at encodi...
متن کاملDirect and Indirect Testing of Memory in Children with Learning Disabilities
This study examined the relation between performance on direct and indirect measures of memory for pictures and words in children with learning disabilities. Recognition memory provided the direct measure and the magnitude of naming facilitation provided the indirect measure. Fourth grade learning disabled and nonlearning disabled children were asked to study a mixed list of pictures and words....
متن کاملNonword repetition priming in lexical decision reverses as a function of study task and speed stress.
The authors argue that nonword repetition priming in lexical decision is the net result of 2 opposing processes. First, repeating nonwords in the lexical decision task results in the storage of a memory trace containing the interpretation that the letter string is a nonword; retrieval of this trace leads to an increase in performance for repeated nonwords. Second, nonword repetition results in ...
متن کاملDirected Forgetting Affects Both Direct and Indirect Tests of Memory
In two experiments, subjects were instructed either to remember or to forget each word. Following study, two tests were given, one a direct test of memory requiring conscious recollection of the study list and the other an indirect test that could be performed without awareness of the study list. In Experiment l, subjects recognized more remember than forget words (direct test) and completed mo...
