We examined recollective experience in odor memory as a function of age, intention to learn, and familiarity. Young and older adults studied a set of familiar and unfamiliar odors with incidental or intentional encoding instructions. At recognition, participants indicated whether their response was based on explicit recollection (remembering), a feeling of familiarity (knowing), or guessing. The results indicated no age-related differences in the distribution of experiential responses for unfamiliar odors. By contrast, for familiar odors the young demonstrated more explicit recollection than the older adults, who produced more know and guess responses. Intention to learn was unrelated to recollective experience. In addition, the observed age differences in remember responses for familiar odors were eliminated when odor naming was statistically controlled. This suggests that age-related deficits in activating specific odor knowledge (i.e., odor names) play an important role for age differences in recollective experience of olfactory information. 相似文献

How something can be said about telling more than we can know: on choice blindness and introspection
Johansson P Hall L Sikström S Tärning B Lind A 《Consciousness and cognition》2006,15(4):673-92; discussion 693-9
The legacy of Nisbett and Wilson’s classic article, Telling More Than We Can Know: Verbal Reports on Mental Processes (1977), is mixed. It is perhaps the most cited article in the recent history of consciousness studies, yet no empirical research program currently exists that continues the work presented in the article. To remedy this, we have introduced an experimental paradigm we call choice blindness [Johansson, P., Hall, L., Sikström, S., &; Olsson, A. (2005). Failure to detect mismatches between intention and outcome in a simple decision task. Science, 310(5745), 116–119.]. In the choice blindness paradigm participants fail to notice mismatches between their intended choice and the outcome they are presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. In this article, we use word-frequency and latent semantic analysis (LSA) to investigate a corpus of introspective reports collected within the choice blindness paradigm. We contrast the introspective reasons given in non-manipulated vs. manipulated trials, but find very few differences between these two groups of reports. 相似文献

Some risk and protective factors differ in their importance to suicidal and nonsuicidal people. In this research we explore the cross-sectional differences between risk factors among suicidal adolescents and nonsuicidal adolescents by focusing on self-esteem. Sixty-five suicidal and 390 nonsuicidal adolescents were compared on Harter's Self-Perceived Profile for Adolescents, self-concept stability, seeking support, loneliness, and depression. Self-concept stability, loneliness, and peer support correlated differently with self-esteem. In multivariate regression analyses, variance in self-esteem was explained by depression and loneliness, and among nonsuicidal adolescents also by self-concept stability, support, and competencies. Loneliness and self-concept stability related differently to self-esteem in suicidal and nonsuicidal adolescents. When the aim is to enhance self-esteem, this difference may delineate suicidal subgroups that need special interventions. 相似文献

Biotechnology emerges in the nexus of academic, political and economic interests. With its strong reliance on a human individual capable of changing matter or organisms in accordance with anticipated goals, biotechnology is closely linked with a modern notion of human agency. In this article, it is argued that in contemporary European societies, biotechnology is perceived in three distinct ways, namely as an agent, as pluripotent, and as salvific. Similar to other forms of technologies, it provides a foil for human activity and projection, but it supersedes them in a quasi religious fashion. The great fascination with the biotechnological enterprise might, thus, express a more fundamental longing for narratives providing coherence and meaning. 相似文献

Scholars disagree about whether adolescent conduct problems (CPs) form a single behavioral syndrome or whether such problems are better conceptualized as different dimensions. The arguments raised by both sides are addressed and tested empirically by analysing data from a large general population sample of Norwegian adolescents (n = 9,342). Confirmatory factor analyses show that a single syndrome of CPs may be subdivided into three highly correlated factors. The first dimension, destructive covert, includes theft and vandalism, whereas the second, nondestructive covert, reflects avoidance of arenas under adult control. The last dimension, overt, includes school opposition and fighting. This three-factor model fits well for both girls and boys, and individuals in their early and late teens. Results from scale analyses are modestly to moderately indicative of a developmental continuum of severity of CPs ranging from nondestructive covert to overt to destructive covert. Taken together the findings imply that both a unidimensional and a multidimensional perspective on CPs are applicable in the general youth population. 相似文献

The authors examined the influence of preclinical dementia and impending death on the cross-sectional relationship between age and performance in tasks assessing episodic memory, visuospatial skill, and verbal fluency. Increasing age was associated with a general decrease in cognitive performance. In addition, those who were to be diagnosed with dementia or had died by a 3-year follow-up, were older, and performed at a lower level than the remaining sample across all cognitive tasks at baseline. Nevertheless, removal of the preclinical dementia and impending death groups from the original sample affected the cross-sectional age-cognition relations relatively little. This pattern of findings suggests that the biological aging process exerts negative influences on cognitive functioning beyond those resulting from disease and mortality. 相似文献

This paper briefly reviews two central assumptions of the levels-of-processing framework in the light of findings from recent PET and fMRI studies: First, to address the suggestion that memory traces can be seen as records of analyses carried out for the purposes of perception and comprehension, studies on encoding-retrieval overlap in brain activation patterns are considered. Second, to address the suggestion that deeper, more semantic, processing results in more durable traces, studies of how encoding activity relates to processing depth and subsequent memory performance are examined. The results show that some of the sensory regions that are activated during initial perception are subsequently reactivated during retrieval, and activity in frontal and medial-temporal brain regions is related to depth of processing and level of memory performance. Collectively, these results provide support for central components of the levels framework. 相似文献

According to Walter Benjamin, we find in the images of recollection and dreams access to a potential of not yet actualized meaning. The images of recollection and dreams are images of the unfulfilled in history, both general and personal. The past has left traces which primarily are the traces of absence. They are traces of something unrecognized in their own time, overseen and forgotten by the course of history. In the sudden moment of recollection, this course can be brought to a standstill, and the images can reveal their salvaging value. 相似文献

The paper seeks to analyze children’s bodily vulnerability as grounded in generational order. The thesis is put forward, that the generational order is embodied via body techniques of vulnerability, deployed both by adults and children. In presenting results from research on professional responses to child maltreatment and neglect, three sets of age related body techniques of vulnerability are identified, concerning caregivers, professionals and the children itself. 相似文献
