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).

Recall,recognition, and confidence patterns in eyewitness testimony

The diversity of methods, contents and tests used in the study of eyewitness memory may have contributed to discrepancies in results in this field. In this experiment, using incidental or intentional learning, we examine the recall and recognition of actions and details concerning the central and peripheral information of a kidnapping. A similar pattern emerges in free recall, hits and recognition confidence: scores are much higher in actions than in central details and there are almost no differences between peripheral actions and details, showing that the distribution of attentional resources is different for actions and details in central than in peripheral information. Although in recall the degree of error was low, in recognition false alarms, especially those in central actions, reduced the level of accuracy to even lower than chance performance in both incidental and intentional groups, also showing that subjects accept false but plausible contents with a high level of confidence.

Diminished response to pleasant stimuli by depressed women

This study examined the self-report and facial expressions of emotional response to pictorial stimuli and the incidental learning of pleasant and unpleasant words by depressed (n = 20) and nondepressed (n = 20) women. Depression was associated with reports of diminished emotional response and reduced frequency and intensity of facial expressions only to pleasant stimuli. The 2 groups did not differ in response to hedonically unpleasant stimuli, even those specifically relevant to the emotion of sadness. In a similar vein, depressed and nondepressed participants showed differences in incidental recall for only pleasant self-referential terms. There was no difference in recall of unpleasant words. These findings suggest the importance of hedonic deficits on psychological processes in clinical depression.     

Intention to learn influences the word frequency effect in recall but not in recognition memory

Watkins, LeCompte, and Kim (2000) suggested that the recall advantage for rare words in mixed lists is due to a compensatory study strategy that favors the rare words. They found the advantage was reversed when rare and common words were studied under incidental learning conditions. The present study investigated the possibility that the rare-word advantage in recognition memory is also the result of a compensatory study strategy. Experiment 1 replicated the findings of Watkins et al. that the rare-word advantage in recall is eliminated under incidental learning conditions. In contrast, Experiment 2 showed that the rare-word advantage in recognition memory is maintained under both intentional and incidental learning conditions. Experiment 3 replicated the results of Experiments 1 and 2 using different stimuli and a different orienting task. Finally, Experiment 4 showed that the rare-word advantage in recognition is maintained with pure lists. These findings show that the rare-word advantage in recognition memory is not the result of a compensatory study strategy. Instead, rare words are encoded more distinctively than common words, irrespective of participants' intention to remember them.

Children's and adults' recall of sex‐stereotyped toy pictures: Effects of presentation and memory task

Gender schema theories predict a memory bias toward sex‐congruent information. The present study examined how presentation of stimuli and encoding conditions influence gender schematic processing in children and adults. One hundred and sixty 5‐ to 13‐year olds and adult males and females viewed 36 sex‐stereotyped toy pictures that were presented in a static and dynamical way. Half of the participants were asked to memorize the pictures (intentional memory) and half were not told that they would be expected to later recall the pictures (incidental memory). Weak gender schematic processing was observed only during the incidental memory task. Children and adults recalled more static than dynamic gender‐stereotyped pictures, and performance was superior in the intentional than in the incidental memory condition. Gender schematic processing was similar across the age groups. In addition, participants were more likely to recall male‐stereotyped toys. Implications for gender schema theories and education are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Oculomotor evidence of sequence learning on the serial reaction time task

Manual and oculomotor measures of sequence learning were examined on the serial reaction time (SRT) task Participants were assigned into four groups differing on response modality (manual, oculomotor) and trial type (sequence, pseudorandom). The pattern of manual RTs replicated previous studies. Frequency of anticipatory eye movements followed similar patterns as RTs. Participants made many anticipations, even in pseudorandom blocks, and frequency of anticipations did not depend on presence of concurrent manual responses. Excluding participants with explicit awareness did not change results. Anticipations were negatively related to RTs in both incidental and intentional learning. Anticipations were positively related to sequence recall in intentional, but not incidental, learning. Results suggest that (1) anticipatory eye movements reflected sequence learning and (2) participants made overt and covert shifts of visuospatial attention to likely stimulus locations prior to stimulus onset, whether or not they made manual responses and whether or not there was a sequence.     

Memory and intelligence: Age and ability differences in strategies and organization of recall

Proficiency at organizing information for recall is one aspect of memory functioning which could be expected to be related to intelligence, or general ability. Comparisons of children of average and of superior ability (Kuhlmann-Anderson scores) in a multitrial free-recall learning task confirmed this prediction: Both level of recall and amount of sequential organization were significantly higher for the superior ability groups. Mental age definitions of intelligence imply that equivalent performance by children of different chronological ages will be based on qualitatively similar cognitive processes. This assumption was not confirmed. Age-related changes in mnemonic strategies were not associated with ability-related differences in recall or organization. Some features of memory development are more dependent on age, whereas others are more dependent on ability. The latter may be best explained in terms of production inefficiency (Flavell, 1970).     

Consistency of seizure frequency estimates across time, methods, and observers

Assessed the consistency of seizure frequency reports across observers, time, and methods. Thirty-two persons with intractable, partial seizures and 17 observers participated in a two-phase assessment procedure. During the first phase, subjects and observers provided retrospective seizure frequency estimates for two consecutive 30-day intervals. During the second phase, subjects and observers completed a daily seizure diary for 30 days. Patients' and observers' retrospective estimates were highly stable over a 2-month period. Substantial consistency was also found between two different recording methods (recall vs. diary) for subjects with epilepsy. In contrast, the observers' retrospective estimates were only moderately correlated with their prospective diary counts. Agreement between subjects' and observers' retrospective reports was also high. However, no significant association was found between their diary counts. Contrary to expectation, seizure frequency reports of patients with partial epilepsy showed moderately high consistency across time and between patient and observer pairs.     

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.     

Can survival processing enhance story memory? Testing the generalizability of the adaptive memory framework

Research from the adaptive memory framework shows that thinking about words in terms of their survival value in an incidental learning task enhances their free recall relative to other semantic encoding strategies and intentional learning (Nairne, Pandeirada, & Thompson, 2008). We found similar results. When participants used incidental survival encoding for a list of words (e.g., "Will this object enhance my survival if I were stranded in the grasslands of a foreign land?"), they produced better free recall on a surprise test than did participants who intentionally tried to remember those words (Experiment 1). We also found this survival processing advantage when the words were presented within the context of a survival or neutral story (Experiment 2). However, this advantage did not extent to memory for a story's factual content, regardless of whether the participants were tested by cued recall (Experiment 3) or free recall (Experiments 4-5). Listening to a story for understanding under intentional or incidental learning conditions was just as good as survival processing for remembering story content. The functionalist approach to thinking about memory as an evolutionary adaptation designed to solve reproductive fitness problems provides a different theoretical framework for research, but it is not yet clear if survival processing has general applicability or is effective only for processing discrete stimuli in terms of fitness-relevant scenarios from our past.     

Verbal rehearsal and selective attention in children with learning disabilities: A developmental lag

To investigate the development of verbal rehearsal strategies and selective attention in learning disabled children, Hagen's Central-Incidental task was administered to younger learning disabled (M CA = 8.68 years) and normal (M CA = 8.62 years) boys in Experiment 1 and to intermediate (M CA = 10.18 years) and older (M CA = 13.48 years) learning disabled boys in Experiment 2. Also, in Experiment 2, an experimentally induced verbal rehearsal condition was included to determine its effects on serial recall and selective attention performance. In Experiment 1, the serial postion curve of the normals revealed both a primacy and a recency effect, whereas that of the learning disabled revealed a recency effect only. In Experiment 2, both the intermediate and the older learning disabled exhibited both primacy and recency effects under both standard and rehearsal conditions. A developmental analysis of central recall for the three learning disabled groups revealed constant age-related increases in overall central recall and in primacy recall. That the normals recalled more central, but not more incidental, information than the learning disabled in Experiment 1 suggests that the learning disabled are deficient in selective attention. Correlational findings suggest that the selective attention of the learning disabled improves with age. The results were interpreted as support for the hypothesis of a developmental lag in the learning disabled population.     

Memory for meaning in skilled and unskilled readers

Skilled and unskilled readers from grades 3, 5, and 7 (9, 11, and 13 years of age, respectively) performed one of three memory tasks on a randomized list of primary word associates. One group rated each word as “good” or “bad” (incidental semantic task), another group produced a rhyming word for each list word (incidental rhyming task), and a third group attempted to memorize the list (intentional learning task). The recall results indicated equivalent recall for skilled and unskilled readers at all grades on the rhyming and intentional tasks; whereas, skilled readers were superior to unskilled readers on the semantic task. A clustering analysis produced a similar effect as skilled readers, who performed the semantic task, tended to cluster semantically-associated words together during recall more readily than unskilled readers. The results were construed as evidence for reading-skill differences in the semantic encoding of individual words.     

Four-year-old children's visual attention in direct and observational learning

The study was designed to compare direct learning (learning by performing) with observational learning (learning by observing) on a memory task that assessed 4-year-old children's selective attention. 17 pairs of kindergarteners of the same sex (aged 3 yr., 8 mo. to 4 yr., 4 mo.) participated in a central-incidental memory task. Data from a retention test indicated that the performers' mean central learning score was higher than their mean incidental score, while the observers showed no difference between their central and incidental learning scores, performers had a higher mean central learning score than observers. On the other hand, the frequency of the subjects' overt visual attention to the task in their learning phase was also counted. Both observers and performers showed high frequency of visual attention.     

Individual differences in phonological learning and verbal STM span

A relationship between phonological short-term memory tasks (e.g., nonword repetition, digit span) and vocabulary learning in both experimental and real-life conditions has been reported in numerous studies. A mechanism that would explain this correlation is, however, not known. The present study explores the possibility that it is the quality of phonological representations that affects both short-term recall and long-term learning of novel wordlike items. In Experiment 1, groups with relatively good and poor span for pseudowords were established. The good group was found to perform better at explicit memory tasks tapping the incidental learning of a limited stimulus pool used in an auditory immediate serial pseudoword recall task. In Experiment 2, the results of Experiment 1 were replicated when experience of correct recall was controlled. In Experiment 3, the immediate recall performance of the good group was found to benefit more than that of the poor group from syllable repetition within stimulus pools. It is concluded that the efficiency of a process that creates phonological representations is related both to short-term capacity for verbal items, and to long-term phonological learning of the structure of novel phonological items.     

内隐学习中的知识习得及其无意识性测量*

本研究采用经典的人工语法范式,并引入迁移任务探讨在记忆和规则探索两种指导语条件下,被试所习得的究竟是规则还是组块？同时采用结构知识主观测量的方法,对内隐学习习得知识的无意识性进行测量。结果发现记忆指导语条件下的被试能成功区分合法串和非法串,即出现语法学习效应,但规则探索指导语条件下的被试并没有表现出语法或组块学习效应,结构知识的主观测量发现这种内隐学习的优势效应主要来自无意识结构知识的贡献;在迁移研究中发现附带学习组和有意学习组均在迁移任务上表现出语法学习效应,这表明在人工语法学习中所获得的语法规则是抽象的和可迁移的。     

Handicapping: the effects of its source and frequency

Using a sample of 246 working adults, the authors created a 2 x 2 x 2 experimental design to isolate the influence of performance outcome, source of handicapping, and frequency of handicapping on reactions to handicapping in organizations. Dependent measures were observers' allocations of credit/blame, interpersonal affect, and the perceived credibility of the explanation. Results showed direct effects on observer impressions for all 3 independent variables, along with a significant Source x Frequency interaction. Handicapping information presented by others yielded more favorable observer impressions than did self-handicapping, and frequent handicapping decreased observer impressions. The least credible handicapping strategy was multiple self-handicaps. A significant 3-way interaction showed that source and frequency affected perceived credibility differently, depending upon whether actual performance was a success or a failure.     

Analytic and holistic modes of learning family-resemblance concepts

Three studies examined how individuals learn concepts structured according to family-resemblance principles. The materials were cartoon faces varying in the attributes of hair, mustache, ears, and nose. In contrast to previous studies purporting to show holistic modes of learning family-resemblance concepts, the present studies indicate that many individuals learn such concepts by an analytic, attribute-plus-exception rule. The attribute-plus-exception rule characterized the learning shown by adults under both intentional (Studies 1 and 2) and incidental (Study 3) learning conditions and by children under intentional learning conditions (Study 2). There was no evidence to indicate that a holistic mode is a more primitive one, since it did not occur more frequently among children or adults under incidental learning conditions. It is suggested that the extent to which holistic or analytic modes of learning are observed will be found to depend on an interaction among stimulus, task, and observer factors.
