Recall Task (recall + task)
Selected AbstractsSelective memory and memory deficits in depressed inpatientsDEPRESSION AND ANXIETY, Issue 4 2003Thomas Ellwart Dipl. Abstract We investigated memory impairment and mood-congruent memory bias in depression, using an explicit memory test and an implicit one. Thirty-six severely depressed inpatients that fulfilled DSM-IV criteria for major depressive disorder and 36 healthy controls matched for sex, age, and educational level participated in the study. Explicit memory was assessed with a free recall task and implicit memory with an anagram solution task. Results showed that depressed and controls differed in explicit memory performance, depending on the amount of cognitive distraction between incidental learning and testing. Implicit memory was not affected. In addition, severely depressed patients showed a mood-congruent memory bias in implicit memory but not in explicit memory. The complex pattern of results is discussed with regard to relevant theories of depression. Depression and Anxiety 17:197,206, 2003. © 2003 Wiley-Liss, Inc. [source] Influence of social network characteristics on cognition and functional status with agingINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 9 2008Ariel Frank Green Abstract Objective To determine whether more frequent engagement in larger social networks, and more emotional support protect against cognitive and functional decline with aging. Methods We examined the influence of social networks on cognition and instrumental activities of daily living (IADLs) over a median interval of 10.9 years. Data were from the Baltimore follow-up of the Epidemiologic Catchment Area (ECA) study, a community-based sample of adults in eastern Baltimore. Eight hundred and seventy-four participants completed cognitive testing at both the third and fourth study waves (1993,1996 and 2003,2004) on the Mini-Mental State Examination (MMSE) and a delayed word recall task. Functional status at both waves was self-reported on the Lawton-Brody IADL scale. Social network characteristics, assessed at the third study wave, included network size, frequency of contact, and emotional support. Results In cross-sectional analyses at wave 3, larger networks were associated with higher MMSE and better delayed recall scores. This association persisted after adjustment for covariates. More emotional support was associated with better functional status, before and after adjustment. By contrast, social networks were not longitudinally associated with cognitive change, with two counter-intuitive exceptions: more frequent contact and more emotional support were associated with worse delayed recall and IADL scores after adjustment. Conclusions There was no evidence of a longitudinal association between social networks and cognition or IADLs, although a clear cross-sectional association exists. Together, these findings suggest the emergence of social isolation in individuals declining in cognition and functioning, rather than a protective effect of social networks.

[source] False memories for a robbery in young and older adultsAPPLIED COGNITIVE PSYCHOLOGY, Issue 2 2009Alaitz Aizpurua The aim of the present study was to analyse memory performance in young and older adults based on a robbery scenario. The study examined free recall and the recognition of actions, people and details, as well as the Remember/Know/Guess judgements that accompanied recognition. Recognition was evaluated both immediately and 1 week later, although performance was not affected by the retention interval. In the free recall task, the older adults remembered less information than the younger adults but we found no differences between the two with regard to errors. Participants accepted more false actions, thus achieving higher recognition accuracy for people and details. They also categorized false alarms for actions more often as remember than as know or guess judgements. This pattern of results was more pronounced in the older adults, suggesting that aging is an important factor in false memories for events. Copyright © 2008 John Wiley & Sons, Ltd. [source] Memory, Maternal Representations, and Internalizing Symptomatology Among Abused, Neglected, and Nonmaltreated ChildrenCHILD DEVELOPMENT, Issue 3 2008Kristin Valentino A depth-of-processing incidental recall task for maternal-referent stimuli was utilized to assess basic memory processes and the affective valence of maternal representations among abused (N = 63), neglected (N = 33), and nonmaltreated (N = 128) school-aged children (ages 8,13.5 years old). Self-reported and observer-rated indices of internalizing symptoms were also assessed. Abused children demonstrated impairments in recall compared to neglected and nonmaltreated children. Although abused, neglected, and nonmaltreated children did not differ in valence of maternal representations, positive and negative maternal schemas related to internalizing symptoms differently among subgroups of maltreated children. Valence of maternal schema was critical in differentiating those with high and low internalizing symptomatology among the neglected children only. Implications for clinical intervention and prevention efforts are underscored. [source] Cognitive biases in depressed and non-depressed referred youthCLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 5 2008Benedikte Timbremont This study examined cognitive vulnerability in both depressed and non-depressed referred youngsters. Formerly depressed (FD) children and adolescents (n = 16) were compared to a currently depressed (CD) group (n = 18) on a self-referent encoding and memory task imbedded in a mood induction paradigm. In order to test the specificity of the findings to depression, the results of the FD were further compared with those of a clinical but never depressed (ND) group (n = 39) diagnosed with anxiety and/or disruptive behaviour disorders. The study confirmed the hypothesized differences between the groups in terms of self-referent encoding bias. Both the ND (p < 0.001) and FD (p < 0.001) group rated more positive words than negative words as self-descriptive while the CD endorsed a closer balance of positive and negative words (non-significant difference). No interaction effect was found for the recall task. The FD group evinced a similar memory bias than the CD group. However, also in the ND group, the number of proportional recalled positive words did not differ from the proportional recalled negative words. The findings yielded no evidence for a depression-specific information-processing bias. However, all subjects (FD, CD as well as ND) exhibited a memory bias and therefore ,clinical status' is considered as a cognitive vulnerability risk factor for developing a depressive disorder in the future.,Copyright © 2008 John Wiley & Sons, Ltd. [source] Cross-cultural study on adult age-group differences in the recall of the literal and interpretive meanings of narrative text1JAPANESE PSYCHOLOGICAL RESEARCH, Issue 2 2006AYA HOSOKAWA Abstract:, This study examined cultural and age differences in the recall of the literal and interpretive meanings of narrative text. Twenty Japanese younger adults (age: M = 21.05, SD = 1.02), 20 Japanese older adults (age: M = 66.95, SD = 1.71), 20 American younger adults (age M = 21.7, SD = 1.76), and 16 American older adults (age M = 69.56, SD = 3.43) participated in this study. One story rich in both literal and interpretive content was used as a stimulus text for two recall tasks, to retell and interpret the story. The response task order was counterbalanced across the participants for each group. When asked to retell a story as close to the original as possible, the younger adults in both of the two cultural groups recalled more of the literal propositions than did the older adults. Both older and younger adults in the two cultural groups recalled more of the main ideas relative to the details; however, when asked to interpret the same story, more older than younger adults represented deep and synthetic representations of the story's interpretive meanings in the Japanese group. The interpretive responses by both the older and younger adults were almost to the same extent on depth; however, the younger adults' responses were slightly higher on synthesis in the American group. These interpretive patterns stem from cultural background. [source] Searching for the Hebb effect in Down syndrome: evidence for a dissociation between verbal short-term memory and domain-general learning of serial orderJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 4 2010E. K. Mosse Abstract Background The Hebb effect is a form of repetition-driven long-term learning that is thought to provide an analogue for the processes involved in new word learning. Other evidence suggests that verbal short-term memory also constrains now vocabulary acquisition, but if the Hebb effect is independent of short-term memory, then it may be possible to demonstrate its preservation in a sample of individuals with Down syndrome, who typically show a verbal short-term memory deficit alongside surprising relative strengths in vocabulary. Methods In two experiments, individuals both with and without Down syndrome (matched for receptive vocabulary) completed immediate serial recall tasks incorporating a Hebb repetition paradigm in either verbal or visuospatial conditions. Results Both groups demonstrated equivalent benefit from Hebb repetition, despite individuals with Down syndrome showing significantly lower verbal short-term memory spans. The resultant Hebb effect was equivalent across verbal and visuospatial domains. Conclusions These studies suggest that the Hebb effect is essentially preserved within Down syndrome, implying that explicit verbal short-term memory is dissociable from potentially more implicit Hebb learning. The relative strength in receptive vocabulary observed in Down syndrome may therefore be supported by largely intact long-term as opposed to short-term serial order learning. This in turn may have implications for teaching methods and interventions that present new phonological material to individuals with Down syndrome. [source] Influence of First Language Orthographic Experience on Second Language Decoding and Word LearningLANGUAGE LEARNING, Issue 1 2008Megumi Hamada This study examined the influence of first language (L1) orthographic experiences on decoding and semantic information retention of new words in a second language (L2). Hypotheses were that congruity in L1 and L2 orthographic experiences determines L2 decoding efficiency, which, in turn, affects semantic information encoding and retention. College-level English L2 learners with typologically similar (Korean) and dissimilar (Chinese) L1 backgrounds were participants. Their decoding efficiency was measured by a pseudoword naming task with phonologically regular and irregular conditions. They learned the meaning of the pseudowords paired with pictures. Subsequent recall tasks showed that the Korean group had better overall retention but greater impairment with the irregular pseudowords. These findings suggest that L1 orthographic distance influences L2 word learning processes. [source] Zolpidem and triazolam interact differentially with a delay interval on a digit-enter-and-recall taskHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 2 2001Craig R. Rush Abstract Zolpidem (AMBIEN®), an imidazopyridine, is now the most commonly prescribed hypnotic in the United States. Zolpidem is neuropharmacologically distinct from benzodiazepine hypnotics in that it binds with low affinity to ,5 -containing GABAA -receptor subtypes. Despite its unique benzodiazepine-receptor binding profile, the results of most of the published studies conducted with humans suggest that the absolute magnitude of impairment produced by zolpidem is comparable to that observed with benzodiazepine hypnotics like triazolam. The present study compared the acute effects of zolpidem (0, 7.5, 15 and 22.5,mg) and triazolam (0, 0.1875, 0.375 and 0.5625,mg) in 10 non-drug-abusing humans using a Digit-Enter-and-Recall task with varying delay intervals (0, 10 and 20,s). To more fully characterize the behavioral effects of zolpidem and triazolam, several other performance tasks and subject-rated drug-effect questionnaires were included. Zolpidem and triazolam impaired performance on the Digit-Enter-and-Recall task as a function of dose under all delay intervals. However, the dose-related effects of the drugs interacted differentially with the delay interval such that zolpidem produced significantly less impairment than triazolam following the longest delay (i.e., 20,s). Zolpidem and triazolam produced comparable dose-related impairment on the digit symbol substitution test (DSST), circular lights task, and picture recall/recognition task. Zolpidem and triazolam generally produced qualitatively and quantitatively similar subject-rated drug effects, although some between-drug differences were observed. Consistent with the pharmacokinetics of these drugs, the effects of zolpidem peaked sooner and were shorter in duration than those observed with triazolam. The results of this experiment suggest that zolpidem may have less potential than triazolam to impair recall, which may be due to differences between these compounds in terms of their benzodiazepine-receptor binding profile. The results of the present study are also concordant with previous studies that found that drugs that act at the GABAA -receptor complex can be differentiated based on their interaction with the delay interval on a Digit-Enter-and-Recall task.
