Working memory load differentially affects tip-of-the-tongue states and feeling-of-knowing judgments
Schwartz BL 《Memory & cognition》2008,36(1):9-19
Tip-of-the-tongue states (TOTs) are judgments of the likelihood of imminent retrieval for items currently not recalled, whereas feeling-of-knowing judgments (FOKs) are predictions of successful recognition for items not recalled. The assumption has been that similar metacognitive processes dictate these similar judgments. In Experiment 1, TOTs and FOKs were compared for general information questions. Participants remembered four digits (working memory load) during target retrieval for half of the questions, and there was no memory load for the other questions. Working memory did not affect recall but decreased the number of TOTs and increased FOKs. In Experiment 2, participants maintained six digits during retrieval. TOTs decreased in the working memory condition, but FOKs remained constant. Experiment 3 replicated the results of Experiment 2 while asking for FOKs for recall. In each of the first three experiments, positive metacognitive judgments also affected working memory performance, supporting the idea that working memory and metamemory use similar monitoring processes. In Experiment 4, visual working memory did not affect TOTs or FOKs. The data support a view that TOTs and FOKs are separable metacognitive entities. 相似文献

This study identified levels of distress, and predictors of levels of distress, in women undergoing assessment for genetic
risk of breast/ovarian cancer based on their family history. It comprised a cohort study following 154 women who completed
questionnaires at entry into a cancer genetic assessment programme and following risk provision. Independent significant associates
of anxiety following risk provision were age, neuroticism, feeling hopeless about developing cancer, a perceived lack of control
over developing cancer, lack of a social confidant, and a coping response involving acceptance/resignation. Depression was
associated with age, neuroticism, feeling hopeless about developing cancer, lack of social confidant, and a coping response
involving acceptance/resignation. To avoid high levels of psychological morbidity in future cohorts undergoing cancer genetic
risk assessment, information should be given that emphasises that some degree of control over health outcomes through behaviour
change or increased surveillance is possible. 相似文献

Vital exhaustion has been implicated in the development and progression of cardiovascular disease. In addition, elevated levels of fibrinogen and D-dimer have been associated with an increased risk of cardiovascular disease. Some studies have suggested that fibrinogen and D-dimer are associated with acute, chronic, and perceived stress. In this issue, Kudielka et al examine the relationship between circulating fibrinogen and D-dimer levels and vital exhaustion in a cross-sectional study of middle-aged teachers in Germany, to examine the plausible link between chronic stress and the development of cardiovascular disease. This commentary discusses the limited available evidence of the mechanisms responsible for the association between vital exhaustion and the development of cardiovascular disease and highlights the limitations of previous research and discusses future directions. 相似文献

Individuals undergoing cancer genetic risk assessment have been found to have a poor understanding of the process, which may
affect how well they cope with learning their risk. This paper reports free-text data from questionnaires completed by women
undergoing a randomised controlled trial of a psychological intervention. Of the 268 women undergoing genetic assessment for
familial breast/ovarian cancer risk who were invited to take part in the trial, 157 women returned research questionnaires.
Of these, 97 women provided free-text comments upon referral to a cancer genetics clinic, 62 provided comments whilst waiting
for risk information (average, moderate or high), and 36 women provided comments following notification of risk. This paper
reports a thematic analysis of the free-text data. Themes reflected individuals’ poor knowledge and uncertainty about genetic
risk assessment. How well individuals responded to learning their risk depended upon whether expectations had been met. Regardless
of risk, individuals undergoing cancer genetic risk assessment are likely to benefit from increased information about its
process and timescales, and access to increased psychological support. Free-text comments can provide valuable data about
individuals’ expectations and knowledge of genetics services. 相似文献

In a number of studies reaction time has been found to increase with increases in size ratio on a same -different form-comparison task. Bennett and Warren (2002, Perception & Psychophysics 64 462-477) teased apart environmental and retinal size ratios by showing the forms along a (simulated) texture hallway, viewed monocularly, on a simultaneous form-comparison task; roughly equal effects of environmental and retinal size ratios were found. The current study enhanced scene-size information by showing the forms in simulated stereo and by adding texture to the forms themselves; special care was also taken to perceptually isolate the stimuli. In two experiments, with different kinds of forms, strong effects of environmental size ratio were found; no effect of retinal size ratio (same trials) was observed in either experiment. The results support the hypothesis that the (same-trial) form-size codings reflect 'all told' estimates of environmental size, and place constraints on modeling the functional architecture of the visual system. 相似文献
