In the present study, we examined age-related differences in utilizing learned associations to guide visual search. Participants viewed an object cue that was associated with 1 or 2 target colors, followed by a search array. Older adults showed slower RTs, larger visual search slopes, and reduced cue–target association knowledge than did younger adults. We also found increased search RTs and higher error rates when the cue was associated with 2 colors instead of 1. However, visual search slopes did not vary with the number of associated colors. This indicates that participants could activate multiple templates simultaneously to guide the search or retrieve associative information directly from the long-term memory. Furthermore, regression analyses showed that VWMC can predict both visual search performances and cue–target association knowledge. More broadly, our results demonstrate that VWMC can modify the effects of age on cued visual search performance. 相似文献

This study investigated the relationship between intraindividual variability (IIV) in reaction time and prospective memory errors in older adults using data from the Zurich Longitudinal Study of Cognitive Aging (n = 336 individuals aged 66–81 years). The results indicated that increased IIV measured from independent tasks was associated with a greater proportion of prospective memory errors. These significant findings were not influenced by age and did not vary according to prospective memory cue type. Variability is thought to reflect fluctuations in attentional and executive control and these attentional processes may also impact on prospective memory through failure to detect the target cue. The findings suggest, therefore, that measures of variability may have some potential in the identification of older persons who are more vulnerable to everyday errors such as prospective memory failures. 相似文献

The present study investigated whether cognitively healthy older adults who are carriers of the ε4 allele of apolipoprotein E, the most prevalent genetic risk factor for late-onset Alzheimer’s disease, benefit from self-referential processing and emotional processing to the same degree as noncarriers of this gene. Participants encoded emotional and nonemotional narratives using a baseline-orienting task, semantic elaboration, or imagination-based self-referential processing and then completed a recognition memory test. Both groups of older adults showed enhanced recognition memory for narrative information following self-referential processing relative to semantic elaboration, and the magnitude of this memory effect was not affected by ε4 status. However, older adult ε4 carriers did not show an emotional enhancement effect, whereas older adult ε4 noncarriers did. These results indicate that whereas the self-reference effect is not attenuated in cognitively healthy older adults ε4 carriers, deficits in emotional memory may be an early cognitive marker of abnormal decline. 相似文献

Subjective cognitive complaints (SCC) and their role as a possible indicator for subsequent dementia became of growing interest in recent research. In contrast to studies that focused primarily on memory complaints, we aimed to (a) evaluate a questionnaire to register SCC in multiple cognitive domains (Complainer Profile Identification, CPI), (b) assess the association between SCC and psychosocial variables, and (c) assess whether complainer types can be differentiated. Confirmatory factor analysis to evaluate construct validity was computed based on a sample of 734 healthy participants (mean [M] = 43.15 years). On a subsample of 644 participants, the relationship between the total level of SCC with age, depression, social integration, and aging stereotypes was assessed utilizing multiple regression analysis. Differences in complainer types were assessed by multivariate analysis of variance. The results indicate sound psychometric properties of the CPI. The overall level of SCC is largely influenced by depressiveness, whereas executive complainers show the highest level of depressive affect, being overall younger and less socially integrated. 相似文献

This multiple case study explored trauma event memories of three individuals to characterise underlying meanings important for their recovery. The three participants were women in the age range of 43 to 54 years old, who shared their own memories of a trauma-laden event four to five years post-occurrence. Thematic analysis of the autobiographical narratives indicated underlying memories across cases of silence imposed on trauma victims by their social environments and communities. Differences in trauma autobiographical memories were in meaning making within the context of the participants’ own culture, society, and community. Autobiographical memory studies appear to have value for understanding likely pathways to recovery from trauma 相似文献

Research suggests that identity and memory are deeply interconnected, but little is known about the identity processes and the memory characteristics involved in this interaction. We employed a longitudinal design to examine relations between the satisfaction of autonomy, relatedness, and competence needs in self-defining memories and identity processing styles within the domain of friendship. We also assessed satisfaction with friends to evaluate the relation of identity processes and memory characteristics to well-being in friendships. Participants were 166 students who responded twice (at about a two-year interval) to the Identity processing style Inventory-3 and the Satisfaction with Life Scale. We adapted these measures to tap into the domain of friendships, which is an important aspect of young adults’ identity. Participants also described a friend-related self-defining memory and rated the degree of need satisfaction they experienced in that event. A cross-lagged panel analysis revealed that memory need satisfaction predicted increases in informational identity processing style and friend satisfaction over time. Implications for the directive function of memory in identity are discussed. 相似文献
