Memory for details with self-referencing

Self-referencing benefits item memory, but little is known about the ways in which referencing the self affects memory for details. Experiment 1 assessed whether the effects of self-referencing operate only at the item, or general, level or whether they also enhance memory for specific visual details of objects. Participants incidentally encoded objects by making judgements in reference to the self, a close other (one's mother), or a familiar other (Bill Clinton). Results indicate that referencing the self or a close other enhances both specific and general memory. Experiments 2 and 3 assessed verbal memory for source in a task that relied on distinguishing between different mental operations (internal sources). The results indicate that self-referencing disproportionately enhances source memory, relative to conditions referencing other people, semantic, or perceptual information. We conclude that self-referencing not only enhances specific memory for both visual and verbal information, but can also disproportionately improve memory for specific internal source details.     

Memory for contextual details: effects of emotion and aging

When individuals are confronted with a complex visual scene that includes some emotional element, memory for the emotional component often is enhanced, whereas memory for peripheral (nonemotional) details is reduced. The present study examined the effects of age and encoding instructions on this effect. With incidental encoding instructions, young and older adults showed this pattern of results, indicating that both groups focused attention on the emotional aspects of the scene. With intentional encoding instructions, young adults no longer showed the effect: They were just as likely to remember peripheral details of negative images as of neutral images. The older adults, in contrast, did not overcome the attentional bias: They continued to show reduced memory for the peripheral elements of the emotional compared with the neutral scenes, even with the intentional encoding instructions.     

Memory for details about people: familiarity,relatedness, and gender congruency

This study examines factors that influence memory for details about people. In two experiments, subjects learned fictitious details about familiar (friends, relatives) and/or unfamiliar individuals, and were tested both immediately and after a 1-week delay. To control for a confounding between familiarity and genetic relatedness in Experiment 1, in Experiment 2 specific relationships (identical twin, first cousin, acquaintance) were assigned to unfamiliar individuals. Across experiments, retention was enhanced for familiar compared to unfamiliar individuals, for friends/acquaintances compared to relatives, for more closely than distantly related individuals, and for individuals of the opposite gender as the subject.     

A multi-level cognitive architecture for self-referencing,self-awareness and self-interpretation

In this paper, a multilevel cognitive architecture is introduced that can be used to model mental processes in clients of psychotherapeutic sessions. The architecture does not only cover base level mental processes but also mental processes involving self-referencing, self-awareness and self-interpretation. To this end, the cognitive architecture was designed according to four levels, where (part of) the structure of each level is represented by an explicit self-model of it at the next-higher level of the architecture. At that next-higher level, states reify part of the structure of the level below; these states have a referencing relation to it. In this way the overall architecture includes its own overall self-model. The cognitive architecture was evaluated for a case study of a realistic type of therapeutic session from clinical practice.     

On self-referencing differences in judgment and choice

Compared to judgment, choice is argued to elicit more self-referent processing and thereby produce greater subsequent recall of evaluated information. This response mode effect is shown to be dependent upon sufficient visualization to overcome the use of heuristic processing during choice. When visualizing prior to the task, choice leads to increased thinking about personal consumption occasions relative to judgment, leading to enhanced recall of vivid (vs. non-vivid) attributes. This proposed interaction of task and visualization was found in two experiments that assessed incidental recall following a choice or judgment task. In experiment 1, participants recalled more vivid product attribute information after choosing between options than after rating each option separately, but only when instructed to visualize during evaluation. To eliminate a comparison-based explanation of this effect, a second experiment was conducted that presented only one option in each category. Participants who evaluated their intention to purchase the option (a judgment equivalent of choice) demonstrated greater recall of vivid product attribute information than did participants who rated their liking for the option, and this recall difference was again moderated by instructions to visualize.     

The effect of self-referencing on memory for different kinds of source information

ABSTRACT

Self-referential processing has been proven to be effective in improving source memory. However, it is unclear whether different types of source information would be consistently enhanced when an item is self-referentially processed. In two experiments, the authors examined the influence of the self (compared with other-referencing and semantic processing) as well as learning intention (incidental/intentional learning) on memory for two types of source information (spatial location and colour) that differ in the amount of cognitive resources they require to be encoded in memory. Results show that self-referencing has enhanced memory for spatial location of words whatever this information is learned intentionally or incidentally, whereas it cannot facilitate memory for the colour of words under the intentional learning condition, nor can it under the incidental condition. These findings suggest that self-referential processing is beneficial in memory improvement but not all-powerful, a source self-reference effect is subject to source information type.     

Effects of self-referencing on feeling-of-knowing accuracy and recollective experience

The current research investigated the impact of self-referencing (SR) on feeling-of-knowing (FOK) judgements to improve our understanding of the mechanisms underlying these metamemory judgements and specifically test the relationship between recollective experiences and FOK accuracy within the accessibility framework FOK judgements are thought to be by-products of the retrieval process and are therefore closely related to memory performance. Because relating information to one's self is one of the factors enhancing memory performance, we investigated the effect of self-related encoding on FOK accuracy and recollective experience. We compared performance on this condition to a separate deep processing condition in which participants reported the frequency of occurrence of pairs of words. Participants encoded pairs of words incidentally, and following a delay interval, they attempted at retrieving each target prompted by its cue. Then, they were re-presented with all cues and asked to provide FOK ratings regarding their likelihood of recognising the targets amongst distractors. Finally, they were given a surprise recognition task in which following each response they identified whether the response was remembered, known or just guessed. Our results showed that only SR at encoding resulted in better memory, higher FOK accuracy and increased recollective experience.     

Memory Interventions for Persons with Dementia

It is possible to design effective, pragmatically useful memory interventions for persons with Dementia of the Alzheimer's Type (DAT). A review of successful memory interventions for such populations is presented. A particularly effective intervention technique, spaced-retrieval, is described and the theoretical basis for its effectiveness is discussed. A detailed account is presented of a spaced-retrieval intervention in which persons with DAT are trained to learn and utilize a strategy, i.e., remembering to use a calendar listing daily activities. Directions for future research in this area are offered.     

Emotional memory for central and peripheral details in children with callous-unemotional traits

A limited number of studies have shown that adults and adolescents with psychopathic traits suffer from emotional memory impairment. The present study examined whether this finding could be replicated in a sample of children between 8 and 12?years of age with callous-unemotional (CU) traits. Children with high CU traits (n?=?24) were compared with children with low CU traits (n?=?18) with regard to performance on a peripheral memory recognition test that examined memory for central and peripheral components of neutral and negative pictures. Results showed that overall recognition rates did not differ between the high- and low-CU groups. For negative pictures, both groups demonstrated better recognition of the central component at the expense of the peripheral component, while for neutral pictures, the peripheral component was better recognized than the central component. This study is the first to demonstrate that children with high CU traits do not suffer from an impaired emotional memory. Copyright ? 2012 John Wiley & Sons, Ltd.     

Memory for Faces in Children with Autism

Previous research has established that children with Autistic Disorder have deficits in aspects of social cognition and in verbal memory, but research on social memory is limited. Twenty-four autistic boys aged 7 to 12 years and normal controls matched for verbal mental age were administered parallel social and nonsocial matching and memory tasks. Results showed that the children with autism were impaired relative to the normal children on the social (face) memory task only. Furthermore, of the four experimental tasks, the social memory task had the highest and most consistent correlations with measures of social development and adaptive skills. Whereas the normal children used the special status of faces to recall them more easily than objects, the children with autism showed equal recall of objects and faces.     

The effect of task relevance instructions on memory for text with seductive details

Seductive details in text are interesting but unimportant text segments. Although seductive details can make expository text more interesting, they do not necessarily promote learning of main ideas. This study investigated whether task relevance instructions that targeted main ideas would promote memory for main ideas when students read a text with seductive details. Undergraduates (n = 102) read a text with seductive detail sentences and then did a free recall task. Before reading, participants received pre‐reading questions that either targeted main ideas or seductive details, or they read for understanding. The main finding was that students in the main idea relevance instruction condition recalled main ideas better than students in the control or seductive detail relevance instruction conditions. Theoretical and practical implications of the results are discussed, and directions for future research are provided.     

Memory for context becomes less specific with time

Context memories initially require the hippocampus, but over time become independent of this structure. This shift reflects a consolidation process whereby memories are gradually stored in distributed regions of the cortex. The function of this process is thought to be the extraction of statistical regularities and general knowledge from specific experiences. The current study examined this idea in mice by measuring the specificity of context memories during consolidation. In the first experiment, separate groups of animals were trained with a single shock and tested in the training context or a novel environment 1, 14, 28, or 36 d later. We found a systematic increase in generalization over this period. Initially, mice froze more in the training context, but fear of the novel environment grew over time until animals eventually froze an equivalent amount in both contexts. The second experiment demonstrated that the increase in generalization was due to a loss of detailed information about the context and not fear incubation. In this experiment, mice were exposed to the context and then trained with an immediate shock 1 or 36 d later. Animals trained 1 d after exposure acquired robust context fear that did not generalize across environments. In contrast, mice trained 36 d after exposure froze an equivalent amount in the training context and the novel environment. The same profile was observed in H-ras mutants that exhibit enhanced hippocampal plasticity and learning. These results suggest that context memories are specific early after training when they require the hippocampus, and become more general as they are permanently stored in the cortex.     

Memory for routes

Two experiments examined the acquisition of cognitive maps of two intersecting routes through an urban area. In the presentation stage of the experiments, slides of the two routes were shown in order to simulate travel along the routes. The number of presentations of the slides was varied. In the test stage, subjects made directional and distance judgements from memory between places on the routes. The results suggest that from the start of acquisition of the spatial layout of the routes, subjects used network schemata in which both routes were combined, rather than a separate scheme for each route which were later combined. During initial acquisitions of the routes, a direction of travel bias was found such that spatial judgements from memory tended to be more accurate in the direction of travel along the routes than in the opposite direction. The findings imply that, at least during early acquisition, the spatial properties of the routes were encoded in terms of sequential associations.     

Memory for emotions

It is argued that memory reproduces emotional data as well as cognitive information. Retrieval of feelings may be cue-dependent, emotionally mediated or coincidental. Infantile emotions can be presumed to vary strongly due to the lack of control, and, poorly labelled, they could produce powerful, but un-identifiable memories, possible components in various adult experiences. In later childhood there is greater independence, and moderately positive memories from this period have possibly fewer “withdrawal effects.” Though an event may be linked with certain remembered feelings at the time of impact, it can later be recombined with other echoes. Remembered emotions can be rewarding, and if they are found to be lacking, substitutes will often be sought, or repressed feelings may surface. These theoretical considerations are applied to the phenomena of anger, depression, and anxiety, each involving (reproduced) feeling-states influencing cognitive processing. “Turning down” the memory channel, or the timely retrieval of positive feelings could increase tolerance in this respect. Human attraction is also briefly analysed.     

Memory for music

Subjects created imaginal interpretations of classical music passages in accordance with themes which were either concrete and comprehensible or abstract and difficult to comprehend. Recognition memory for the musical passages was found to be superior in the former condition. The results support the hypothesis that meaningful interpretation of stimulus material is a major determinant of memory accuracy. The implications of the results for comparisons of music and language are also discussed.     

Memory for metaphors

Three experiments examined memory for metaphorical sentences. No differences between metaphors and nonmetaphorical equivalents (e.g.,The ivy cuddled up to the window vs.The ivy grew up to the window) in the number of correct recalls or recognitions were found. There was, however, a significant trend for recall errors that were meaning-preseving to be less metaphorical than the input sentence. The results supported hypotheses that metaphors and nonmetaphors are equally easy to remember and that the stored memory representation does not distinguish whether its antecedent linguistic input was metaphorical or not.This research was supported by Grant MH 28493-01 from NIMH and by a grant from the Kansas State University Bureau of General Research.Some of the data were reported at the Meeting of the Psychonomic Society, Denver, November 1975.     

Memory for Conversation

Memory for conversation is treated as a source of coherence in social encounters and its connections with social competence are tested in a study of problemsolving conversations. As predicted, accurate recall is found to correlate positively with social competence and negatively with social anxiety. Partners have better memory for their own contributions than for each other's, and this difference is exacerbated by topic importance. Differences in recall are also found for differing amounts of involvement in the conversations. Results are explained in terms of resource allocation during conversation.     

Memory for memory

Participants read short passages and 1 day later they answered questions via telephone about the passages (text facts) and about the experimental session (event facts). They were telephoned again 6 weeks later and answered the same questions about text and event facts. They also answered new questions about whether they remembered the answers they had given in the initial telephone interview (recall for prior memory performance). Although participants accurately remembered the majority of past memory successes, they were poor at remembering past memory failures. After being provided with the correct answer and tested again, the participants' performance improved somewhat, especially for memory failures. This suggests that some errors in recalling past forgetting might have been due to correctly remembering the answer previously given, but failing to realize that it had been wrong. These findings have implications for a variety of situations in which people are queried about past memory performance.
