In March 2020, in response to the COVID-19 pandemic, Canadian provincial governments instituted a variety of public health measures that included social distancing and isolation, which may have had unintended consequeses. According to the Loneliness and Sexual Risk Model, gay, bisexual, and other men who have sex with men (GBM) often cope with loneliness through risky sexual behaviors. Previous studies have demonstrated that COVID-19 measures such as social distancing and isolation led to increases in loneliness; thus, these measures may also have led to elevated sexual risk-taking among some GBM. Participants were recruited from an ongoing cohort study on GBM health and well-being, and were included in the current analysis if they had completed relevant study questions (n = 1134). GBM who reported lower levels of social support pre-COVID-19, were younger, and lived alone each reported greater loneliness during the first year of COVID-19. Although feelings of loneliness did not predict sexual risk-taking within the first year of COVID-19, loneliness did predict greater sexual risk-taking 6 months later. Additionally, younger GBM and those living alone were more likely to engage in sexual risk-taking at both COVID-19 data collection points. These findings offer some support of the Loneliness and Sexual Risk Model; however, it is possible that the unique circumstances of the COVID-19 pandemic resulted in a temporary suspension of this association, as many GBM took steps to protect themselves and partners in the context of COVID-19. 相似文献

Response latencies were obtained from 10 Ss in auditory signal-detection experiments. The response latencies were inversely related to certainty that a signal was (or was not) presented. The S’s decision criterion was found to have an influence on response latency, which was consistent with the hypothesis that stimuli close to the current criterion elicit longer response latencies than stimuli more distant from the criterion. Comparisons among receiver operating characteristics derived from binary decisions, from the latencies of binary decisions, and from confidence ratings show that response latencies and binary decisions together yield more information about the stimulus than does the binary decision alone. However, the increment in information gained from the measurement of response latencies is in general (though not for every S) smaller than that gained by shifting from yes-no responses to a confidence-rating procedure. 相似文献

Twenty-seven university students judged whether each of 128 drawings of parallelopipeds appeared to represent three-dimensional rectangular boxes. Half the pictures could not geometrically have been projections of rectangular boxes. The null hypothesis that Ss’ judgments were unrelated to geometry was rejected at the .001 level of significance, and the correlation between Ss’ judgments and perfect discrimination averaged .86 over three variations of the experiment. The results support a general hypothesis about the perception of simple space forms according to which viewers impose geometric constraints, such as rectangularity and symmetry, but only when the constraints are projectively possible. 相似文献

Ss judged grayness of neutral value Munsell chips under two response conditions: magnitude estimation and graphic rating. In addition, they judged average grayness of pairs of chips under the same two response modes. The averaging data were evaluated in terms of a simple model for subjective averaging. The graphic rating data fitted the model, but the magnitude estimates showed consistent discrepancy. It was concluded that the Ss were averaging, but that magnitude estimation distorted their judgments. 相似文献

Conclusion If, as Schmitt suggests, Heidegger bases the claim that moods are cognitive on the philosophical distinction between theoretical and non-theoretical knowing, then much of what Heidegger says in this connection turns out to be either unclear, trivially true, or else false. Yet Schmitt himself only occasionally seems to recognize how dubious this account really is. Moreover, in attempting to help Heidegger say what he means, Schmitt's interpretation in Chapter 5 falters. It falters because(1) the emphatic likening of moods to skills,(2) the introduction of the bizzare notion knowing how occurrently, and (3) the misconceiving of self-deception, are not to be found in Sein und Zeit. They represent, rather, an imposition upon Sein und Zeit from without. This fact means either that Schmitt's interpretation is faulty or else that it is as much reconstructive as explicative. And if reconstructive, then several conceptual mistakes are attributable to him more than to Heidegger. In spite of these difficulties Martin Heidegger on Being Human is a prize book. It attempts to understand a thinker better than he understood himself. And according to Schleiermacher this is the goal of every hermeneutic.In contrast to the successful parts of the book, the chapter on moods fails to make sense out of Heidegger's view - one reason being, I would guess, that Heidegger is, after all, equivocating on the German word Stimmung. Sometimes he uses it to refer specifically to states such as being depressed, being serene, being anxious. At other times he uses it to refer vaguely to Dasein's attunement to the world. If the human being is always already (immer schon) attuned to the world, and if such a posture toward the world is also considered a mood, then in some imprecise way one's being in a mood might be a necessary condition for any belief to affect him emotionally. But, of course, mood in this broad sense would indicate an ontologically, and not a causally, necessary condition. And so, it would not follow that every belief which affected one emotionally need have some specific mood (e.g., depression, serenity, anxiety) as its necessary causal antecedent. Nor would it follow that, as a matter of fact, a change of belief could not effect a specific change of mood.I fear that with regard to some topics the sense in which one understands Heidegger better than he understood himself may well be the original Socratic sense: one knows what Heidegger himself does not know, viz., that the conceptions of Sein und Zeit are not always intelligible. And one wonders whether any philosophical midwifery can really be of aid - at least with respect to the claim that moods are cognitive. 相似文献

The vocal behavior of three Cebus monkeys was maintained by fixed-ratio schedules of response dependent reinforcement at values between fixed-ratio 1 and fixed-ratio 15. In one monkey that was exposed to variable-interval, fixed-interval, and conjunctive fixed-ratio fixed-interval schedules of reinforcement, vocal responding occurred at a low rate, but schedule-appropriate patterns were maintained. The rates and patterns of responding engendered indicated that the vocal operant can be brought under schedule control in the monkey by the use of response-dependent reinforcement. 相似文献

Overextinction of the GSR component of the orienting response was examined in a sample of 68 socially disturbed adolescents. Continued stimulus repetition beyond the point of habituation resulted in GSR return after 50–60 stimulus presentations. However, division of Ss into sleep and non-sleep groups using behavioral and self-report criteria, failed to support Sokolov’s (1963) notion that overextinction is accompanied by drowsiness. A possible explanation of these results is discussed. 相似文献

The asymptotic distributions of response probabilities in the Audley-Jonckheere learning model, as applied to the two-choice learning situation, are described for (1) the experimenter-controlled events model, (2) the subject-controlled events model, and (3) the experimenter-subject-controlled events model. 相似文献

This article describes an electronic switch that allows presentation of sine wave stimuli without the often undesirable transient thump, thud, or click usually caused by ordinary electromechanical switches. 相似文献
