Relation between verbal recall and visual recognition of the same stimuli in young children

Five-year-old children (N = 112) were shown drawings of common objects three times either as a naming-and-learning task or as a preference task (incidental learning). A verbal recall test followed by a class- and item-recognition test, scaled to reflect the accuracy of item recognition, were given either 2 min or two weeks after presentation. Intentional learning with naming led to better immediate recall than incidental learning, but the recognition and delayed recall scores were equal for the two learning conditions. The probability of verbal recall of object names was in each case uncorrelated with the accuracy of visual recognition of the same objects by the same Ss. The results are closely similar to those obtained with adult Ss by Bahrick and Boucher (1968).     

Prediction outcome and choice reaction time: Inhibition versus facilitation effects

In two-choice RT tasks Ss verbally predicted all stimulus presentations, two-thirds of the presentations, or none of the presentations. Effects of stimulus probability were similar for each type of prediction trial: Correct Prediction Outcome (PO), Incorrect PO, and No-Prediction (NP). When comparisons between Prediction and NP trials were between Ss, reactions on NP trials were significantly faster than reactions POs, but were not slower than reactions to Correct POs. However, when Prediction and NP trials occurred within Ss, reactions on NP trials were not faster than reactions to Incorrect POs, but were significantly slower than reactions to Correct POs. Speculations about Ss' implicit stimulus predictions are offered to interpret differential implications of inhibition and facilitation.     

The Measurement of Retinal Fatigue to Achromatic Stimulation–I

Experiment I was conducted to investigate memory in a concept identification (CI) problem as a function of the number of trials that precede the recall task. It was found that the recall performance on the initial trials of CI problems was quite good, but declined rapidly when the recall test was given on later trials. It was pointed out that the bulk of the solutions to CI problems are obtained by Ss during the initial trials where an S has good recall for past stimuli. In Experiment II, recall by Ss in a normal CI problem was compared to the recall by Ss in an incidental learning control group. As the performance of Ss in a normal CI problem was significantly better, it was concluded that Ss actively try to store and retain information during their search for a solution.     

Free recall and retrieval speed of categorized items by kindergarten children

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.     

Effects of vicarious consequences on imitation and recall: Some developmental findings

Two experiments were conducted using a multiple-item list in which each item consisted of a pair of pictures. The model indicated which member of each pair she preferred and was either positively reinforced, negatively reinforced, or received neutral consequences. The S then indicated his preferences (imitation test). Following the imitation test, each S was asked to recall the model's choices. Age was an independent variable in both experiments. Imitation scores of the children, preschool to sixth-grade age range, were strongly influenced by differential vicarious reinforcement. Vicarious reward increased imitation and vicarious punishment decreased it. College students' imitation scores were only minimally influenced by differential vicarious reinforcement. Within- and between-subjects variations of vicarious reinforcement had similar effects. Recall scores were surprisingly high and were not significantly influenced by differential vicarious reinforcement. Interestingly, age and percentage of correct recall were negatively correlated.     

Developmental changes in apportionment of study time among items in a multitrial free recall task

First grade, third grade, and college Ss attempted to memorize a single set of items over the course of 5 trials, each trial consisting of a 45-sec study period followed by a free recall test. On all trials but the first, S was allowed to have available during his study period only half of the total set of items, but was free to select whichever items he wished to include in this half. Third grade and college Ss were significantly more prone than first grade Ss to select for study items not recalled in the immediately preceding recall test. The results suggest that the strategy of deliberately concentrating one's study activities on the less well mastered segments of materials to be learned, like other elementary memory strategies (e.g., rote rehearsal), cannot automatically be assumed to be part of a young child's repertoire of learning techniques.     

The generality of word-association hierarchies: I. Production and recall of association responses

Ss responded to a stimuluslist in a free word association session (AS) and tried to recall their response to each stimulus in a recall session (RS). There was a significant positive correlation between commonality score (Co) in AS and number of correct reproductions in RS. All Ss tended to gain in Co, but LC (i.e., Ss of low Co in AS) more than HC (i.e., Ss of high Co in AS).     

Domain-specificity in perfectionism: Variations across domains of life

Perfectionism has been assessed in relation to salient or narrow domains within specific populations, yet little is understood across broader domains of life. The aim was to assess positive perfectionism (PP) and negative perfectionism (NP) in five broad domains; university/work, relationships, physical activity, domestic environment and appearance and to determine any gender differences within domains. One hundred and forty four university students (females n = 101; males n = 43) completed a modified perfectionism measure for each domain. Correlations within and between domains for PP and NP ranged from low to moderate with differential patterns by gender, supporting more domain specificity and less of a universal trait. Repeated measures ANOVAs revealed that, overall, PP and NP in the university/work domain was significantly higher than all other domains. Females reported greater PP in the university domain compared to other domains, and more PP in the relationship, domestic environment and appearance domains as compared to the physical activity domain. In contrast, males reported significantly higher PP in the physical activity domain. Females reported significantly higher NP in the university and appearance domains, while males had similar NP across all domains. These findings present a more complex picture of perfectionism with implications for domain-specificity in perfectionistic behavior.     

Eye movements and visual imagery in free recall

The relationship between eye movements and visual imagery has almost exclusively been studied by treating eye movements as the dependent variable while an imagery task is being performed. In the present experiment three eye-movement treatment conditions were manipulated, within Ss, as the independent variable in order to study their effects on the free recall of nouns which Ss had to store by means of imagery. The imagery-evoking capacity (I) of nouns was varied over three levels within lists of Dutch nouns (Low, Medium and High I). Ss were instructed to generate a visual image to each separate noun under the following treatment conditions: (a) while they looked over and scanned their image as if they were looking at the real object: (b) while they received concurrent visual stimulation from a checkerboard pattern; (c) while they fixated on a target. Reliable, but minor effects of treatment conditions on the recall scores were found. The results were discussed in terms of possible theories about the nature of the relationship between eye movements and visual imagery.     

The role of imagery in incidental learning of educable retarded and normal children

Forty-five educable retarded and 45 normal children were given an orientation task in which noun- and picture-paired associates were presented once or four times under one of three instructional conditions: intentional imagery, incidental imagery, or intentional control (no imagery). An immediate associative recall test showed both imagery conditions to be superior to the intentional control condition. Furthermore, imagery instructions facilitated incidental recall of the retarded Ss equal to the recall of normal children in the intentional condition. Four presentations of pairs in contrast to one presentation during the orientation task improved the learning of both groups. The recall of retarded Ss in contrast to normal Ss, however, was greater with four presentations under imagery instructions than under intentional control instructions. The results were discussed in terms of imagery processes and their educational implications.     

Concept identification with natural material.

Phonetic letters in Japanese (Hiragana, 23 in number) written by 6 adults (Ws) were presented one by one and the S was asked to guess by which W it was written. Immediately after the S made the guess, the code of correct W was given on each trial. The Ss were Japanese housewives, students etc., 53 in number. Rate of correct identification increased during 23 × 6 trials, but only from 0.3 to 0.4 on the average. The learning transferred to the remaining 23 letters of the same kind but not to letters of the other kind (Katakana). On each trial, the S verbally described cues upon which the guess was made. When the data were separately analysed according to Ws, it was found that letters of the W who was most difficult to identify were most ‘diffused’ in characterization by the Ss. The relevance of the present experiment to study of concept identification in general was also discussed.     

Differential recall of successes and failures: Its relationship to defensiveness,achievement motivation,and anxiety

Differential recall of completed and incompleted tasks under high and low stress was studied in 157 Ss. On the basis of repression, it would be expected that Ss identified as hysterics would recall fewer incompletions (ego threatening failures) under high than low stress. The results indicated that hysteria was not related to recall. On the other hand, Ss with high achievement motivation or low anxiety recalled more incompletions under high than low stress while there were no differences in their recall of completions under high and low stress. These results offered no support for repression. Furthermore, the relationships between recall and achievement motivation and anxiety suggest that the differential recall is due to differences in the original learning of the completed and incompleted tasks.     

The Perception of Mechanical Vibration: III. The Frequency Function

Three studies of male and female undergraduates examined the effects of incidental orienting tasks on the free recall of concrete nouns. In Experiments 1 (between-Ss design N = 53) and 2 (within-Ss design N = 54) semantic orienting tasks resulted in recall that was equal to or higher than recall following intentional learning. Nonsemantic orienting tasks produced poorest recall. In Experiment 3 (N = 59), Ss performed a word recognition task between two free-recall trials. The target and distractor words were either acoustically, orthographically, or semantically related or were unrelated to each other. On the second free-recall trial, recall was highest for target words that had been paired with semantically related distractors. The results of the three experiments add to the growing support for a levels-of-processing model of memory.     

Effects of the temporal relationship of feedback and stimulus information upon discrimination-learning strategies

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. In one condition (/+3) feedback was delivered immediately upon S's response while the stimuli were still in view. In another (/0) feedback was also immediate but stimuli were extinguished immediately upon S's response. In the third condition (/?3), stimuli were extinguished immediately upon response and feedback was delayed 3 sec. Major findings among the children were (a) Ss of all conditions coded information at the same (high) average efficiency, (b) Ss of conditions /0 and /?3 recoded with significantly less efficiency than those of /+3, and (c) Ss in condition /+3 manifested primarily efficient information-processing strategies, those in condition /0 showed intermediate performance, and those of condition /?3 showed relatively primitive stereotyped behavior. Among adult Ss performance was uniformly high with little effect on any response measure investigated.     

The processing of affectively-toned words in incidental learning: a test of differential acquisition and response bias hypotheses.

Differential acquisition of stimulus information and differential response biases have been considered as hypotheses for the processing of affective stimuli in perceptual tasks. The present experiment was designed to assess the value of these hypotheses in the context of recall following incidental learning. During the first two phases of the experiment, 70 undergraduates were led to believe that the investigation was concerned with their efficiency at letter-cancelling. In the first phase, the Ss copied out out a mixed list of good and bad words, twice, as quickly as possible, and then began work on a letter- cancelling task. In the second phase, each S participated in one of five further word- copying conditions, once again completed as quickly as possible and followed by more letter-cancelling. These conditions served to create different degrees of acquisition for the good and bad words or to create suitable controls.Using a new method of analysing recall data, differences between the mean strenghts of the good and bad words were estimated on a logistic scale. Analysis of this data yielded no evidence to support either of the initial hypotheses. Similarities and discrepancies between the present findings and the existing literature are discussed. It is suggested that an advantage in recall for good as against bad words may only emerge ehen Ss allocate additional processing to good words, either through choice or as a consequence of task demands.     

Learning of lists of properties related to familiar objects

Four groups of Ss simultaneously learn six-word lists that indicate common objects' properties. Words of each list may either all correspond to the same object (highest homogeneity level), or, inversely, correspond to six different objects (highest heterogeneity level), with two intermediate situations in between.The homogeneity of lists has a main effect upon learning. It is hypothesized that the object corresponding to the words of a list is used, when it is detected, as a federator for this words, and thus facilitates their recall. It is concluded there is a certain similarity between word lists corresponding to several properties of an object and taxonomic lists.     

Learning strategies as determinants of memory deficiencies

Two tests were made of inferences about how learning strategies affect recall accuracy, and how peculiarities of strategy might account for mentally retardeds' memory deficiencies. Learning strategy was defined as the pattern of pauses generated by S as he paced himself through serial lists of letters. When given freedom to proceed as they wished, normally intelligent Ss paused increasingly the deeper they went into the list. Retarded Ss did not. It was concluded that the normals' active strategies contribute to their high primacy, while the retardeds' lack of distinctive pauses accounts for their low primacy. In the second test, the strategies were reversed. The normals were forced to abandon rehearsal; the retardeds were forced to rehearse. This resulted in greatly enhanced primacy for the retardeds, and greatly decreased primacy for the normals. In addition to showing how spontaneous strategies and forced strategies can directly influence recall accuracy, these findings suggest a reasonably simple means of mitigating short-term memory deficiencies.     

Effects of a coactor's prediction on latencies to predict and indentify stimuli

On each of 300 trials E's confederate (C) verbalized which of two stimuli would occur; then S made a prediction. Following each presentation, S and C pulled a trigger to identify the stimulus. Two latencies were measured: the interval between C's and S's prediction (prediction time), and the interval between stimulus presentation and S's identification response (choice RT). Prediction times were significantly shorter when S's prediction agreed rather than disagreed with C's prediction, when S's preceding prediction was correct rather than incorrect, and when S was female rather than male. Choice RT was influenced by distributions of C's stimulus predictions and C's prediction outcomes in directions supporting an expectancy model.     

Age differences in organization and recall: The effects of training in categorization

An alternating sort/recall task was employed to train fourth graders and college students in organizational strategies. Free-sorting Ss, at both age levels, sorted a group of words into two to seven categories. Analyses of final sorting patterns indicated reliable differences between the children and adults. The organizational schemes thus developed by the free-sorting Ss were taught, by means of a yoking procedure, to other Ss. Results indicated that the recall of fourth graders was improved when they were forced to learn the sorting patterns developed by the older Ss. Similarly, impairment in the recall of college students was observed when they were required to sort according to the organization employed by the fourth graders. These findings imply that changes in organization can result in changes in recall performance.     

Positive contrast obtained in reacquisition following interpolation of nonreinforced or partially reinforced trials

Two experiments investigated the effects of shifting from either nonreinforcement or partial reinforcement (PRF) to continuous reinforcement conditions (CRF). In the first experiment, three groups of rats were given food reinforcement under CRF conditions in a runway followed by regular extinction trials (RE), extinction trials where Ss were delayed for 30 sec before entering the empty goal box (DE), or CRF trials where Ss were delayed for 30 sec before entering the baited goal box (DF). Then all Ss were run on the delayed reinforcement condition (DF). In the final delayed reinforcement condition, group DE ran significantly faster than group DF, reflecting positive contrast. In the second experiment, four groups of rats were trained in a runway to receive either 4% or 18% sucrose reinforcers under either PRF or CRF conditions. Then all Ss were transferred to a Skinner box and bar presses were continuously reinforced, with each S continuing to receive the same sucrose concentration as before. The former PRF Ss, regardless of the reinforcer, bar pressed at a significantly higher rate in the Skinner box than the former CRF Ss. The evidence seemed to favor the view that the effectiveness of a reinforcer is not an absolute, unchanging quantity but rather depends on the historical context in which the reinforcer occurs.
