Implicit Memory (implicit + memory)
Selected AbstractsFunctions of remembering and misremembering emotionAPPLIED COGNITIVE PSYCHOLOGY, Issue 8 2009Linda J. Levine Memory for the emotions evoked by past events guides people's ongoing behaviour and future plans. Evidence indicates that emotions are represented in at least two forms in memory with different properties. Explicit memories of emotion can be retrieved deliberately, in a flexible manner, across situations. Implicit memories of emotion are brought to mind automatically by cues resembling the context in which an emotional event occurred. One property they share, however, is that both types of memory are subject to forgetting and bias over time as people's goals and appraisals of past emotional events change. This article reviews the cognitive and motivational mechanisms that underlie stability and change in memory for emotion. We also address functions that remembering and misremembering emotion may serve for individuals and groups. Although memory bias is typically viewed as problematic, changes in representations of emotional experience often promote goal-directed behaviour and facilitate coping with challenging situations.

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] Implicit memory is independent from IQ and age but not from etiology: evidence from Down and Williams syndromesJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 12 2007S. Vicari Abstract Background In the last few years, experimental data have been reported on differences in implicit memory processes of genetically distinct groups of individuals with Intellectual Disability (ID). These evidences are relevant for the more general debate on supposed asynchrony of cognitive maturation in children with abnormal brain development. This study, comparing implicit memory processes in individuals with Williams syndrome (WS) and Down syndrome (DS), was planned to verify the ,etiological specificity' hypotheses pertaining to the skill learning abilities of individuals with ID. Method A modified version of Nissen and Bullemer's (1987) Serial Reaction Time (SRT) task was used. The performances of three group were evaluated. The first group consisted of thirty-two people with WS (18 males and 14 females). The second group was comprised of twenty-six individuals with DS (14 males and 12 females). The two groups of individuals with ID were selected so that the groups were comparable as for mental age and chronological age. The third group consisted of forty-nine typically developed children with a mental age similar to that of the groups with WS and DS. Results The two groups of individuals with ID demonstrated different patterns of procedural learning. WS individuals revealed poor implicit learning of the temporal sequence of events characterizing the ordered blocks in the SRT task. Indeed, differently from normal controls, WS participants showed no reaction time (RT) speeding through ordered blocks. Most importantly, the rebound effect, which so dramatically affected normal children's RTs passing from the last ordered to the last block, had only a marginal influence on WS children's RTs. Differently from the WS group, the rate of procedural learning of the participants with DS was comparable to that of their controls. Indeed, DS and typically developed individuals showed parallel RT variations in the series of ordered blocks and, more importantly, passing from the last ordered to the last block. Therefore, a substantial preservation of skill learning abilities in this genetic syndrome is confirmed. Conclusions The results of the present study document that procedural learning in individuals with ID depends on the aetiology of the syndrome, thus supporting the etiological specificity account of their cognitive development. These results are relevant for our knowledge about the qualitative aspects and the underlying neurobiological substrate of the anomalous cognitive development in mentally retarded people. [source] Effect of midazolam on memory: a study of process dissociation procedure and functional magnetic resonance imagingANAESTHESIA, Issue 6 2010S. Y. Tian Summary To assess the effects of midazolam on explicit and implicit memories, 12 volunteers were randomly divided into the two groups: one with an Observer's Assessment of Alertness/Sedation score of 3 (mild sedation) and one with a score of 1 (deep sedation). Blood oxygen-level-dependent functional magnetic resonance imaging was measured before and during an auditory stimulus, then with midazolam sedation, and then during a second auditory stimulus with continuous midazolam sedation. After 4 h, explicit and implicit memories were assessed. There was no evidence of explicit memory at the two levels of midazolam sedation. Implicit memory was retained at a mild level of midazolam sedation but absent at a deep level of midazolam sedation. At a mild level of midazolam sedation, activation of all brain areas by auditory stimulus (as measured by functional magnetic resonance imaging) was uninhibited. However, a deep level of midazolam sedation depressed activation of the superior temporal gyrus by auditory stimulus. We conclude that midazolam does not abolish implicit memory at a mild sedation level, but can abolish both explicit and implicit memories at a deep sedation level. The superior temporal gyrus may be one of the target areas. [source] Absence of explicit and implicit memory in unconscious patients using a TCI of propofolACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2003P. Y. Lequeux Background:, ,Episodes of implicit memory have been described during propofol anaesthesia. It remains unclear whether implicit memory is caused by short periods of awareness or occurs in an unconscious subject. Methods:, Sixty patients were randomized in an experimental group (EG), a control group (CG) and a reference group (RG). Loss of consciousness (LOC) was obtained by progressive stepwise increases of propofol using a target-controlled infusion device (Diprifusor, Alaris Medical Systems, San Diego, CA). A tape containing 20 words was played to the patients in the CG before the start of anaesthesia and to the patients in the EG at a constant calculated concentration of propofol associated with LOC. The tape was not played to the patients in the RG. Three memory tests were performed postoperatively. Results:, Explicit and implicit memories were evidenced in the CG but not in the EG. Conclusion:, In our group of young ASA I/II patients, in the absence of any noxious stimulus, no implicit or explicit memory was found when the calculated concentration of propofol using a Diprifusor was maintained at the level associated with LOC. [source] The placebo response complexTHE JOURNAL OF ANALYTICAL PSYCHOLOGY, Issue 5 2004Richard Kradin Abstract:, Placebo effects contribute to beneficial therapeutic responses and are common in anxiety and depressive disorders. It is posited that placebo effects are yielded by autonomous feeling-toned complexes capable of re-establishing background self-states of well-being. The relationship between the placebo response complex and modern neurobiological models of self is explored. The psychological roots of the placebo response complex in implicit memories of organized attachment between child and early caretakers and in Sandler's conception of the benign superego are examined. The relationships between the negative placebo (nocebo) response complex, Freud's negative therapeutic reaction, and Fordham's defence of the self are explored. Finally, it is suggested that approaches fundamental to the analytic encounter, e.g., mirroring, affectual exchanges, attunement, and containment are likely to optimize the salutary effects of both psychological and somatic therapeutic interventions.

[source] Neuropsychological functioning in older people with Type 2 diabetes: the effect of controlling for confounding factorsDIABETIC MEDICINE, Issue 4 2002K. G. Asimakopoulou Abstract Aims and methods Neuropsychological functioning was examined in a group of 33 older (mean age 62.40 ± 9.62 years) people with Type 2 diabetes (Group 1) and 33 non-diabetic participants matched with Group 1 on age, sex, premorbid intelligence and presence of hypertension and cardio/cerebrovascular conditions (Group 2). Results Data statistically corrected for confounding factors obtained from the diabetic group were compared with the matched control group. The results suggested small cognitive deficits in diabetic people's verbal memory and mental flexibility (Logical Memory A and SS7). No differences were seen between the two samples in simple and complex visuomotor attention, sustained complex visual attention, attention efficiency, mental double tracking, implicit memory, and self-reported memory problems. Conclusions These findings indicate minimal cognitive impairment in relatively uncomplicated Type 2 diabetes and demonstrate the importance of control and matching for confounding factors.

[source] Memories, fantasies, archetypes: an exploration of some connections between cognitive science and analytical psychologyTHE JOURNAL OF ANALYTICAL PSYCHOLOGY, Issue 4 2001Jean M. Knox The value of cognitive science as a means of investigating psychodynamic theory and practice is discussed and the limitations of this approach are described. Research findings from cognitive science are drawn on to clarify the nature of memory, which is seen to be a mixture of reproduction and reconstruction and the concepts of true and false memory are explored in this light. The part played by implicit memory and internal working models in producing transference is also examined. New ways of conceptualizing fantasy, which describes it as another facet of internal working models, and the role of transgenerational transmission of attachment patterns in creating internal working models are explored. The nature of archetypes is considered in the light of cognitive science research and a minimalist model is proposed, in which they can be likened to image schemas, that is, primitive conceptual structures that exist in a form which can never be experienced directly or indirectly.

[source] Effects of retrieval practice on conceptual explicit and implicit consumer memoryAPPLIED COGNITIVE PSYCHOLOGY, Issue 2 2009Andrew Parker Two experiments are reported that investigate the effects of retrieval practice on explicit and implicit memory for brand names. In Experiment 1, participants were exposed to a set of brand names pertaining to a range of product categories. Following this, participants practiced retrieving a subset of the brands before taking an explicit or implicit test for the brands. The explicit test, required recall of the brands in response to product category cues. The implicit test required the generation of the first brand names that came to mind. In both tests, prior retrieval produced retrieval-induced forgetting of the non-practiced brands. Experiment 2 replicated this effect under conditions designed to reduce explicit contamination. In addition, Experiment 2 found that increasing the amount of retrieval practice also increased the magnitude of retrieval-induced forgetting on the explicit but not the implicit test. Implications for advertising and marketing are considered. Copyright © 2008 John Wiley & Sons, Ltd. [source] | |||||||||||||
