累积压力假说与匹配-不匹配假说均可解释远端和近端逆境对个体抑郁的影响, 但鲜有研究考察遗传基因在其中的调节作用。采用问卷法和DNA分型技术, 对970名青少年进行间隔3年的追踪调查。分别以母亲消极教养、同伴侵害为远端和近端压力指标, FKBP5基因多位点累加得分为遗传指标, 考察三者对青少年抑郁的交互作用及性别差异。结果发现, 在男青少年中, E × E × G显著。当累加得分较高、同伴侵害水平较高时, 母亲消极教养显著负向预测抑郁, 符合匹配-不匹配假说; 累加得分较低时, E × E不显著, 但倾向于以累积压力假说的方式发挥作用。女青少年中, E × E × G不显著。研究结果提示, 在男青少年中, 累积压力假说与匹配-不匹配假说均可阐明抑郁的发生机制, 分别适用于携带不同FKBP5基因多位点累加得分的个体。 相似文献

Many everyday decisions have to be made under risk and can be interpreted as choices between gambles with different outcomes that are realized with specific probabilities. The underlying cognitive processes were investigated by testing six sets of hypotheses concerning choices, decision times, and information search derived from cumulative prospect theory, decision field theory, priority heuristic and parallel constraint satisfaction models. Our participants completed 40 decision tasks of two gambles with two non‐negative outcomes each. Information search was recorded using eye‐tracking technology. Results for choices, decision time, the amount of information searched for, fixation durations, the direction of the information search, and the distribution of fixations conflict with the prediction of the non‐compensatory priority heuristic and indicate that individuals use compensatory strategies. Choice proportions are well in line with the predictions of cumulative prospect theory. Process measures indicate that individuals thereby do not rely on deliberate calculations of weighted sums. Information integration processes seem to be better explained by models that partially rely on automatic processes such as decision field theory or parallel constraint satisfaction models.

In this paper, through the study of the clinical process of a girl starting treatment at the age of 3 years 10 months, who was thought of as a dummy by her family and who came for consultation when the assumed genetic aetiology was questioned, the authors build upon Tustin's contributions on the context of togetherness and the crisis of two‐ness, and upon Eugenio and Renata Gaddini's on the precursor object. The mimetic phenomena enacted with an older brother and at the kindergarten are found to result from cumulative trauma at her contacting a loving but mind–blind mother. After an initial stage of transference autism, enactment in the session of the traumatic situation was the first step in surmounting her autistic pseudo–stupidity. Mimetic transference dynamics took place principally at the level of the gaze, leading to the unfolding of the work of two–ness to a differentiation from the analyst as psychic breast, on the road to symbol formation and personal agency. 相似文献

By using a video‐based narrative (unidirectional) eyewitness statement of an alleged victim, participants were asked to imagine they were police officers. We compared the quality of mock police officer written records in a between‐subjects design comprising three conditions: (a) a free recall (n = 27), (b) a free recall by using recall strategies of the cognitive interview (n = 27), or (c) note taking while watching the video (n = 26). The quality of the reports was determined by the amount of correctly recalled details, omitted details, added details (commission errors), and changed details (confabulations). As predicted, the number of correct details was higher in the “Note Taking” condition whereas performance in the “Free Recall” and in the “Cognitive Interview” conditions did not differ. Higher verbal memory ability resulted in a better quality of the written records. Our results suggest that note taking facilitates the quality of written records. 相似文献

This paper concerns ordinal responses. An ordered Dirichlet distribution describes prior and posterior beliefs about the cumulative probabilities of response categories. Associating the response categories with intervals of a latent random variable then induces a distribution on the order statistics of that variable. The psychometrician can use the asymptotic theory of order statistics to learn how distributional assumptions about the latent variable effect inference. An example relates the skewness of a latent variable to the proportional odds and proportional hazards models of McCullagh [1980]. 相似文献

This study evaluated a cumulative dosing procedure for drug discrimination with human participants. Four participants learned to discriminate triazolam (0.35 mg/70 kg) from placebo. A crossover design was used to compare the results under a single dosing procedure with results obtained under a cumulative dosing procedure. Under the single dosing procedure, a dose of triazolam (0, 0.05, 0.15, or 0.35 mg/70 kg) or secobarbital (0, 25, 75, or 175 mg/70 kg) was administered 45 min before assessment. Determining each dose-effect curve thus required four sessions. Under the cumulative dosing procedure, four doses of triazolam (0, 0.05, 0.10, and 0.20 mg/70 kg) or secobarbital (0, 25, 50, and 100 mg/70 kg) were administered approximately 55 min apart, producing a complete dose-effect curve in one four-trial session. Regardless of procedure, triazolam and secobarbital produced discriminative stimulus and self-reported effects similar to previous single dosing studies in humans. Shifts to the right in cumulative dose-effect curves compared to single dose-effect curves occurred on several self-report measures. When qualitative stimulus functions rather than quantitative functions are of interest, application of cumulative dosing may increase efficiency in human drug discrimination. 相似文献

Precision Teaching's unique legacy from B. F. Skinner was the monitoring system of rate of response and the cumulative response recorder. This legacy is unique because the other instructional systems derived from Skinner's work do not use his monitoring method exclusively. Rate of response, cumulative recording and their extension to Precision Teaching's standard celeration charting are briefly described. In addition, Precision Teaching's nature, history, costs, distribution, inductive data-base, and academic base are briefly described. Skinner's legacy to education was a sound behavioral scientific base and his unique legacy to Precision Teaching was self-monitoring for real time decision making by learners and teachers. 相似文献
