The recency effect: implicit learning with explicit retrieval?

Abstract

The recency effect in free recall features prominently in 1960s' theorizing about short-term memory, but has since been largely ignored. We argue that this stems from a preoccupation with the role of recency in the concept of primary memory and the neglect of its role in a broader working-memory framework. It is suggested that the recency effect reflects the application of an explicit retrieval strategy to the residue of implicit learning within a range of cognitive systems. When retrieved implicitly, the same residue is assumed to form the basis of priming effects. The various criteria for implicit learning described by Tulving and Schacter (1990) are successfully applied to the recency effect, and a retrieval process is outlined that can account for both long- and short-term recency effects. It is suggested that a framework combining recency, priming, and implicit learning provides a basis for understanding one of the most important features of cognition and memory, namely, that of maintaining orientation in time and place.

Enhancement of selective listening by illusory mislocation of speech sounds due to lip-reading.

Mechanisms of human attention allow selective processing of just the relevant events among the many stimuli bombarding our senses. Most laboratory studies examine attention within just a single sense, but in the real world many important events are specified multimodally, as in verbal communication. Speech comprises visual lip movements as well as sounds, and lip-reading contributes to speech perception, even for listeners with good hearing, by a process of audiovisual integration. Such examples raise the problem of how we coordinate our spatial attention across the sensory modalities, to select sights and sounds from a common source for further processing. Here we show that this problem is alleviated by allowing some cross-modal matching before attentional selection is completed. Cross-modal matching can lead to an illusion, whereby sounds are mislocated at their apparent visual source; this crossmodal illusion can enhance selective spatial attention to speech sounds.

Just say no: how are visual searches terminated when there is no target present?

How should a visual search task be terminated when no target is found? Such searches could end after a serial search through all items, but blank trials in many tasks are terminated too quickly for that to be plausible. This paper proposes a solution based on Wolfe's (1994) Guided Search model. The probability that each item is a target is computed in parallel based on items' differences from each other and their similarity to the desired target. This probability is expressed as an activation. Activations are examined in decreasing order until the target is found or until an activation threshold is reached. This threshold is set adaptively by the observer--more conservative following misses, more liberal following successful trials. In addition, observers guess on some trials. The probability of a guess increases as trial duration increases. The model successfully explains blank trial performance. Specific predictions are tested by experiments.

Induction of a memory retrieval strategy by young children.

This study examines children's modification of their own retrieval processes in a cued recall task. Each experiment had multiple study-test trails with triplets of categorically related words (Horse-Pig-Cow). Category-orienting questions were asked at acquisition, and each trial had different triplet stimuli. The last triplet word was the target, and the retrieval cues were the whole-context cue (Horse-Pig), a part context cue (Horse), or a noncontext associate (Goat). The measure of retrieval induction was recall increases across trials. Experiments 1 and 3 examined retrieval support for induction by 7- to 12-year olds by manipulating cue type. Experiments 2 and 4 manipulated acquisition variables that might effect retrieval induction. The results showed induction of an effective retrieval strategy in the situations of maximum retrieval support even by the 7-year olds, and developmental differences occurred in the situations where the retrieval cues provided few hints about the acquisition encoding operation. The results suggest that monitoring and modification of retrieval processes should be distinguished and that monitoring is necessary but not sufficient for induction of an effective retrieval strategy. The results have implications for understanding children's strategy-utilization deficiencies in memory tasks.
