Daily affective reactivity refers to the within-subject relationship between daily stress and daily mood. Most stress researchers have conceptualized daily affective reactivity as a dependent variable to be predicted by individual difference variables such as personality and psychopathology. In contrast, in our recent research, we have conceptualized daily affective reactivity as an independent variable that can predict depressive symptoms. In this article, we summarize three studies that relied on a daily process methodology and multilevel modeling to assess affective reactivity in the context of daily stressful events. Two of the studies (Cohen, Butler, Gunthert, & Beck, 2005; Gunthert, Cohen, Butler, & Beck, 2005) sampled adult outpatients in cognitive therapy and evaluated the predictive role of daily affective reactivity in treatment outcome (depression reduction). A third study (O'Neill, Cohen, Tolpin, & Gunthert, 2004) evaluated the predictive role of college students' daily affective reactivity in the development of depressive symptoms. We consider the strengths and weaknesses of a daily process methodology for research on depression in both clinical and nonclinical samples. 相似文献

Currently, behavioral development is thought to result from the interplay among genetic inheritance, congenital characteristics, cultural contexts, and parental practices as they directly impact the individual. Evolutionary ecology points to another contributor, epigenetic inheritance, the transmission to offspring of parental phenotypic responses to environmental challenges-even when the young do not experience the challenges themselves. Genetic inheritance is not altered, gene expression is. Organismic pathways for such transmission exist. Maternal stress during the latter half of a daughter's gestation may affect not only the daughter's but also grand-offspring's physical growth. The author argues that temperamental variation may be influenced in the same way. Implications for theory and research design are presented along with testable predictions. 相似文献

In this research, anticipatory perception of an approaching vehicle was examined. By varying the availability of visual and acoustic media, conditions occurred in which the input to the modalities was repetitively interrupted while the presentation of the approach event continued. In these conditions, the audio and the visual signals were presented either in short and concurrent segments at regular intervals or in alternation (interleaved) at regular intervals. It was found that interrupting the signal within a single modality did not affect performance if the approach information was available in the alternate modality. These results are consistent with a modally flexible detection mechanism for the perception of approaching objects. This modal flexibility may provide some evidence that information is detected using a modality-neutral strategy. 相似文献

The allocation of visual attention was investigated in two experiments. In Experiment 1 (n = 24), a peripheral cue was presented, and in Experiment 2 (n = 24), a central cue was used. In both experiments, cue validity was 90%, and the task was four-choice target identification. Response time distributions were collected for valid trials over five cue-target stimulus onset asynchronies (SOAs), and ex-Gaussian parameters were extracted. In both experiments, only the mean of the Gaussian component decreased as a function of cue-target SOA, which implied a strict time axis translation of the distributions. The results were consistent with sequential sampling models featuring a variable delay in the onset of information uptake. 相似文献

If people represent concepts with perceptual simulations, two predictions follow in the property verification task (e.g., Isface a property of GORILLA?). First, perceptual variables such as property size should predict the performance of neutral subjects, because these variables determine the ease of processing properties in perceptual simulations (i.e., perceptual effort). Second, uninstructed neutral subjects should spontaneously construct simulations to verify properties and therefore perform similarly to imagery subjects asked explicitly to use images (i.e., instructional equivalence). As predicted, neutral subjects exhibited both perceptual effort and instructional equivalence, consistent with the assumption that they construct perceptual simulations spontaneously to verify properties. Notably, however, this pattern occurred only when highly associated false properties prevented the use of a word association strategy. In other conditions that used unassociated false properties, the associative strength between concept and property words became a diagnostic cue for true versus false responses, so that associative strength became a better predictor of verification than simulation. This pattern indicates that conceptual tasks engender mixtures of simulation and word association, and that researchers must deter word association strategies when the goal is to assess conceptual knowledge. 相似文献

Three studies tested the hypothesis that thoughts about alternatives become increasingly accessible over time, leading poor outcomes to feel subjectively farther away and less inevitable. This subjective temporal distance bias was obtained even though actual time since poor and good outcomes was identical. In Study 1, participants who recalled distant poor team outcomes thought of alternatives easily and outcomes felt farther away and less inevitable. Thoughts about outcomes were most easily accessible after good outcomes, which felt closer and more inevitable. In Study 2, with measures obtained immediately or at a later time on a negotiation task, changes over time occurred primarily for poor team outcomes. In Study 3, team performance on an investment task indicated it is whether alternatives are thought of easily, not thought content, that produces this effect. Discussion centers on temporal appraisals, other temporal biases, and teams. 相似文献

We evaluated changes in subjective well-being (SWB), motivation, and values occurring over the law-student career. In study 1, law students began with levels of SWB higher than a comparison sample of undergraduates, but by the end of the first year their SWB had plummeted. These changes were correlated with the sample-wide decreases in intrinsic motivation over the first year, and were also correlated with increases in appearance values and decreases in community service values. Those with the most intrinsic motivations attained the highest grades, but, ironically, high grades in turn predicted shifts in career preferences towards "lucrative" and higher-stress law careers, and away from "service"-oriented and potentially more satisfying law careers. The declines persisted over the second and third years of law school. In study 2, the basic effects were replicated for a different sample of first-year students at a different law school. Implications for legal education and the legal profession are discussed. 相似文献

The World Health Organization (WHO) provides annual mortality statistics from 1950 onward based on the International Classification of Diseases (ICD). In this paper we evaluate the effects of ICD form revisions on suicide rates for 71 countries. The changes between ICD-6, ICD-7, ICD-8, and ICD-9 did not have an overall effect on reported suicide rates. The transitions to ICD-8 and ICD-9 were, however, associated with country-specific changes in the suicide rate in some countries. The change from ICD-9 to ICD-10 was associated with an overall change of -.73 suicides per 100,000 inhabitants. It is recommended that researchers using the WHO mortality data for longitudinal cross-national studies control for the ICD form used at different time points. 相似文献

Apolipoprotein E (APOE) genotype is a possible influence on nonpathological cognitive aging. The authors studied 462 community-dwelling, 79-year-old people born in 1921, whose childhood IQ had been assessed in the Scottish Mental Survey of 1932 (Scottish Council for Research in Education, 1933). Adjusting for sex, childhood IQ, and self-reported illnesses, the authors found that those with an APOE e4 allele had significantly lower Wechsler Logical Memory (D. Wechsler, 1987) scores than those without an e4 allele. Those people with APOE s2/e3 genotypes had significantly higher Wechsler Logical Memory scores than e3/s3, who were significantly higher than e3/e4. Neither nonverbal reasoning nor verbal fluency were affected. In this sample, APOE genotype contributed to verbal memory in old age. 相似文献
