Aging,memory load,and resource allocation during reading 总被引:2,自引:0,他引:2
To test the notion that aging brings an inability to self-initiate processing, the authors investigated the effects of memory load on online sentence understanding. Younger and older adults read a series of short passages with or without a simultaneous updating task, which would be expected to deplete resources by consuming memory capacity. Regression analyses of word-by-word reading times onto text variables within each condition were used to decompose reading times into resources allocated to the array of word-level and textbase-level processes needed for comprehension. Among neither the young nor the old were word-level processes disrupted by a simultaneous memory load. However, older readers showed relatively greater levels of resource allocation to conceptual integration than the younger adults when under load, regardless of working-memory span or task priority. These results suggest that the ability to self-initiate the allocation of processing resources during reading is preserved among older readers. 相似文献

When people use a computer application, they have the opportunity to adapt the methods or strategies that they deploy to better fit the demands of the task. In Experiment 1, we demonstrated that the generation of methods is limited by, but not entirely prevented by, the reduced opportunity that is associated with the iterative nature of typical computer-based tasks. In Experiment 2, we demonstrated that the cognitive demands associated with task-related problem solving delay, but do not prevent, the generation of more efficient device strategies. We argue that people are rather good at adapting device strategies to task demands and that previously reported arguments to the contrary are premature. 相似文献

The application of functional neuroimaging to the study of human emotion has yielded valuable data; however, the conclusions
that may be drawn from any one study are limited. We applied novel statistical techniques to the meta-analysis of 106 PET
and fMRI studies of human emotion and tested predictions made by key neuroscientific models. The results demonstrated partial
support for asymmetry accounts. Greater left-sided activity was observed for approach emotions, whereas neural activity associated
with negative/withdrawal emotions was symmetrical. Support was also found for affect program emotion accounts. The activation distributions associated with fear, disgust, and anger differed significantly. These emotions
were most consistently associated in activity in regions associated with selective processing deficits when damaged: the amygdala,
the insula and globus pallidus, and the lateral orbitofrontal cortex, respectively. In contrast, the distributions for happiness
and sadness did not differ. These findings are considered in the context of conceptualizations of the neural correlates of
human emotion. 相似文献

Experiments were conducted in which observers learned to classify simple perceptual stimuli into low-variability and high-variability categories. Similarities between objects were measured in independent psychological-scaling tasks. The results showed that observers classified transfer stimuli into the high-variability categories with greater probability than was predicted by a baseline version of an exemplar-similarity model. Qualitative evidence for the role of category variability on perceptual classification, which could not be explained in terms of the baseline exemplar-similarity model, was obtained as well. Possible accounts of the effects of category variability are considered in the General Discussion section. 相似文献

“Historicism” has become a ubiquitous and equivocal term. A classification is given here of five separate uses of the term currently in vogue, each provided with a unique qualifying adjective to help keep them distinct. I then offer a few objections to some of the more radical conclusions which have been drawn by proponents of a specific version of historicism, one associated with “postmodernism “. The positions of Rorty and Putnam are contrasted as examples of strong and weak degrees of historicism, respectively. 相似文献

Low‐SES couples have limited resources to manage the chronic and acute stressors with which they are disproportionately faced. Although these couples are at greater risk for negative individual and relationship outcomes, evaluations of the impact of couple relationship education (CRE) in low‐SES couples have been plagued by methodological problems, most notably challenges associated with recruitment and retention. We review the literature on challenges couples face associated with low‐SES, as well as on recruitment, retention, and CRE in low‐SES, ethnic minority populations. We illustrate some of these challenges in a case study of CRE for low‐SES couples transitioning to parenthood. In this pilot study, 21 couples were recruited from a community health clinic and randomized to either an experimental treatment condition (EXP; N = 11) or a treatment‐as‐usual control condition (TAU; N = 10). This study sought to mitigate documented challenges with recruitment and retention: We leveraged community partnerships, attempted to build and maintain strong relationships with study participants, provided incentives for assessments as well as intervention meetings, and attempted to reduce potential barriers to enrollment and retention. Nonetheless, we had low rates of recruitment and retention. We integrate these findings and experiences with our review of previous work in this area. We make recommendations for future CRE research and practice that have potential implications for public policy in this area. 相似文献

In his article ‘Doing, allowing, and the problem of evil’ recently published in this journal, Daniel Lim attempts to undermine the following claims with respect to God: (1) the doing-allowing distinction exists and (2) the doing-allowing distinction is morally significant. I argue that Lim’s attempt is unsuccessful, and that his understanding of divine providence has the unacceptable consequence of implying that God is the originator of evil. 相似文献

This article discusses the following question: what epistemic relation must audiences bear to the content of assertions in order to gain testimonial knowledge? There is a brief discussion of why this issue is of importance, followed by two counterexamples to the most intuitive answer: that in order for an audience to gain testimonial knowledge that p they must know that the speaker has asserted p . It is then suggested that the argument generalises and can be made to work on different sets of assumptions about the conditions for knowledge, and the conditions under which a proposition is asserted. 相似文献

A guiding question for this special section, sparked by the increasing number of studies on callous –unemotional traits (CU traits) and the DSM-5 Limited Prosocial Emotion (LPE) specifier, is whether CU traits are enough to identify a clinically meaningful subgroup of youth with conduct problems or whether other psychopathic traits contribute. Seven empirical papers and two commentary papers address this question to varying degrees and in different ways with some papers “competing” various models against one another along with other papers investigating distinct correlates of the psychopathy factors. Findings across the papers suggest that there could be benefits to examining the broader construct of psychopathy in addition to examining its underpinning dimensions rather than CU traits alone. Two commentary papers also shed light on the importance of psychopathic traits in children with Conduct Disorder (CD) and provide insights for future work on this topic. It is hoped that the articles and commentary will generate new ideas for research and practice that could have implications for the treatment of those individuals with CD and psychopathic traits. 相似文献
