Spaced retrieval (SR) has recently been modified to target anomia in persons with aphasia (PWA). It relies on a strict management of the inter-stimulus interval (ISI) where the time between stimulus presentations is doubled or halved based on response accuracy. Although SR is successful in treating anomia, it remains to be studied whether the…

According to current psychological models of deduction, people can draw inferences on the basis of information that they receive from different sources at different times. In 3 reading-comprehension experiments, the authors demonstrated that premises that appear far apart in a text (distant) are not accessed and are therefore not used as a basis…

Complex working memory span tasks have been shown to predict performance on a number of measures of higher-order cognition including fluid abilities. However, exactly why performance on these tasks is related to higher-order cognition is still not known. The present study examined the patterns of errors made on two common complex span tasks. The…

Previous studies have suggested better learning when people actively intervene rather than when they passively observe the stimuli in a judgment task. In 4 experiments, the authors investigated the hypothesis that this improvement is associated with a shift from exemplar memory to cue abstraction. In a multiple-cue judgment task with continuous…

Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that…

This experiment assesses spatial and nonspatial relational memory in freely moving 9-mo-old and adult (11-13-yr-old) macaque monkeys ("Macaca mulatta"). We tested the use of proximal landmarks, two different objects placed at the center of an open-field arena, as conditional cues allowing monkeys to predict the location of food rewards hidden in…

Procedural and declarative memory systems are postulated to interact in either a synergistic or a competitive manner, and memory consolidation appears to be a highly critical stage for this process. However, the precise cellular mechanisms subserving these interactions remain unknown. To investigate this issue, 24-h retention performances were…

A recent proposal suggests that dyslexic individuals suffer from attentional deficiencies, which impair the ability to selectively process incoming visual information. To investigate this possibility, we employed a spatial cueing procedure in conjunction with a single fixation visual search task measuring thresholds for discriminating the…

This paper investigates the processes by which visual mental images--the precept-like short-term memory representations--are created from information stored in long-term memory. It also presents a new method for studying image generation. Three experiments were conducted using college students as subjects. In the first experiment, a Podgorny and…

One hundred forty-four subjects received 4 Brown-Peterson trials with recall triads from a common encoding category. Items on three trials were from a common subset, while on the fourth, the subset was shifted or not, and a cue was presented or not. The cue influenced response generation, a shift improved recall.

Age-related improvement of mnemonic performances of children has attracted many investigators wishing to determine developmental mechanisms which might produce this improvement. Potential explanations have been subsumed under three major categories: capacity, strategies, and knowledge structures. The present investigation, in focusing on…

This paper presents a developmental study of the effects of item rehearsal on children's short term memory. Two experiments are discussed. The first, involving second and sixth grade children, concerned the relationship between item retrieval ability and rehearsal strategies in item recall. The design of the experiment involved varying the visual…

To develop a coherent description of the knowledge and processes involved in skillful word recognition, a study was devised in which 16 adults participated in four related experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords and to discover basic differences in…

Three experiments are reported investigating the relationship between response recall and the spacing of repetitions as a function of the retention interval. The results of the experiments support the theory which emphasizes the nature of the cues available for retrieval. (Author/RM)

The use of directive cues to facilitate recall and clustering of verbal materials in good and poor readers is investigated. Overall results indicate strong and positive effects of directive cues on the subjects' recall and organization of memory, and indicate that poor readers are unadaptive learners who appear to have a performance deficit,…
