Recognition without identification.

Abstract

The ability of people to recognize words that they could not identify was examined. After studying a list of 15 words, participants completed a word fragment test consisting of 4-letter fragments of both studied and nonstudied words. Whether they were able to solve a particular fragment or not, participants then made an episodic recognition judgment. Even when participants were unable to solve a fragment, their recognition accuracy was significantly higher than chance. This effect was significant when list length was increased, when 2-letter fragments were used, when first letters were excluded from fragments, and when the letter casing and the presentation modality were changed from study to test. It also occurred when participants attempted to identify fragments at study and rated words at test. Recognition without identification is attributed to the use of orthographic information when determining the familiarity of a test item.
