Summary The method of fixed set (Uznadze, 1966) was applied to the size-weight illusion. After the repeated lifting of a small, heavy stimulus and a large, light one with both hands simultaneously, the size-weight illusion diminished. It increased after lifting a small, light stimulus and a large, heavy one. These changes in perception were explained as contrast effects caused by the sets which were fixed during the preceding lifts. The same method was applied to the weight-size illusion and the contrast effect was observed in some cases. The results of the application of the fixed-set method to the size-weight illusion and to the visual size perception were compared. All the results showed analogous patterns of conflicting states between the temporarily fixed set and the set that the subject prepares naturally for perception, such as the size-weight illusion. By way of conclusion, the size-weight illusion was assumed to be a kind of contrast effect in the light of Uznadze's theory of set. 相似文献

Participants saw a standard scene of three objects on a desktop and then judged whether a comparison scene was either the same, except for the viewpoint of the scene, or different, when one or more of the objects either exchanged places or were rotated around their center. As in Nakatani, Pollatsek, and Johnson (2002), judgment times were longer when the rotation angles of the comparison scene increased, and the size of the rotation effect varied for different axes and was larger for same judgments than for different judgments. A second experiment, which included trials without the desktop, indicated that removing the desktop frame of reference mainly affected the y-axis rotation conditions (the axis going vertically through the desktop plane). In addition, eye movement analyses indicated that the process was far more than a simple analogue rotation of the standard scene. The total response latency was divided into three components: the initial eye movement latency, the first-pass time, and the second-pass time. The only indication of a rotation effect in the time to execute the first two components was for z-axis (plane of sight) rotations. Thus, for x- and y-axis rotations, rotation effects occurred only in the probability of there being a second pass and the time to execute it. The data are inconsistent either with an initial rotation of the memory representation of the standard scene to the orientation of the comparison scene or with a holistic alignment of the comparison scene prior to comparing it with the memory representation of the standard scene. Indeed, the eye movement analysis suggests that little of the increased response time for rotated comparison scenes is due to something like a time-consuming analogue process but is, instead, due to more comparisons on individual objects being made (possibly more double checking). 相似文献

Physical activity and psychological stress were hypothesized to improve more in participants with high self-efficacy than in those with low and medium self-efficacy after a one-week intervention. 39 female university students participated. The intervention had two steps: a lecture on self-monitoring and goal setting (160 min.) and a one-week pedometer intervention. Analyses were conducted on tertile groups according to self-efficacy at baseline. Pedometer step counts were higher in the high self-efficacy group than in the low self-efficacy group after intervention. Helplessness decreased time dependently after intervention only in the high-self-efficacy group. Because physical activity improved more in the high self-efficacy group after a one-week intervention, one hypothesis was supported. 相似文献

Culture-related differences in visual creativity were investigated, comparing Italian and Japanese participants in terms of divergent (figural completion task) and product-oriented thinking (figural combination task). Visual restructuring ability was measured as the ability to reinterpret ambiguous figures and was included as a covariate. Results showed that in divergent thinking, Italians only outperformed Japanese participants in elaboration and in product-oriented thinking in terms of originality of products. Visual restructuring ability was found to play a key role both in originality and practicality of products. Both groups scored the same in terms of fluency, originality, and flexibility of visual divergent thinking, as well as in term of practicality of creative products. These findings are consistent with the idea that Italians and Japanese have the same creative potential, although from the early stages of the design Japanese seem to show a greater tendency to take practicality constraints into account when creating in the visual domain. 相似文献

Globally, the COVID-19 pandemic has impaired every aspect of life, especially causing much psychological damage—for instance, increasing the risk of suicide. Intense fear and anxiety are considered to play a central role in mental health problems. This study examined the psychological properties of the Japanese version of the Fear of COVID-19 Scale (FCV-19S) using classical test theory (CTT) and item response theory (IRT). Five hundred fifty participants aged 18–69 years and from across Japan completed questionnaires, including the Japanese FCV-19S, the Japanese Depression Anxiety Stress Scales-15 (DASS-15), and the Japanese version of the Kessler 6 (K6). CTT showed that each item of the Japanese FCV-19S had no ceiling and floor effect and was close to the normal distribution, and IRT revealed that each item had an appropriate parameter of discrimination and difficulty. Finally, the Japanese FCV-19S was shown to have an acceptable reliability and moderate good concurrent validity. Consequently, the Japanese FCV-19S has robust psychometric properties and can be useful for early detection of adults impacted by the COVID-19 pandemic. 相似文献

Coping orientation and psychological distress in healthcare professionals: The utility of appraising coping acceptability 下载免费PDF全文
Hiroshi Morimoto Hironori Shimada Hideki Tanaka 《The Japanese psychological research》2015,57(4):300-312
The purpose of this study was to examine interaction effects of healthcare professionals' coping orientation (i.e., engagement versus disengagement) and appraisal of coping acceptability (ACA) on psychological distress, taking into account the individuals' job specificity and the psychological climate in their work environment. A cross‐sectional survey was conducted, and Japanese healthcare professionals (N = 189; 117 female; mean age: 40.1 ± 11.2 years) reported the coping strategies that they employed for task‐related or interpersonal stressors, their cognitive appraisal of the stressors, their ACA, and the psychological distress evoked by the stressors. The results showed that adding consideration of the ACA to the variable of coping orientation significantly improved predictions of psychological distress for both task and interpersonal stressors. There was no significant interaction between the coping orientation and the use of coping strategies that incorporated the ACA. These results suggest that considering the ACA, in addition to the coping orientation, would be useful for understanding individual differences in the mediators of healthcare professionals' coping in stressful situations. 相似文献

The cognitive behavioral approach for families of individuals with hikikomori (IWH) places importance on assessing family interaction from a behavior theory. However, there is no gold standard method for the assessment of family interaction of IWH. Additionally, the characteristics of the family interactions of IWH have not been clarified. This study aims to (a) develop the Family Interaction Scale for Hikikomori (FIS‐H) using parent‐reported data, and (b) clarify the characteristics of hikikomori cases. First, the FIS‐H factor structure was examined. Second, to examine the reliability and validity of the FIS‐H and the characteristics of hikikomori cases, parents of IWH (hikikomori‐group) and unaffected parents (without‐group) completed the FIS‐H and the Relationship Happiness Scale. Based on data from 146 parents, the FIS‐H preliminary version consisted of four factors with a total of 12 items (Study 1). The reliability and validity of the FIS‐H were also confirmed to be acceptable using data from 246 hikikomori‐group participants. The hikikomori‐group had higher FIS‐H scores than did the without‐group (Study 2). These results show that it is important to appropriately assess family interactions. 相似文献

The effects of variations in signal probability and varying degrees of correct feedback on response bias were studied in a yes-no auditory signal detection task. The main finding was that the bias towards saying yes was an increasing function of the frequency of signal feedback events, but did not depend on the correctness of the feedback. Several learning models coupled with a simple psychophysical and decision model yielded predictions about overall biases and certain sequential statistics. Only one model, which can be decribed as an “informational” model, gave a good account of both observed overall biases and sequential statistics. This model assumes the observer’s response bias is strengthened for the feedback-reinforced response when the observer’s sensory information is ambiguous or is contradicted by the feedback information. 相似文献

When control subjects compared the sizes of two circles of different lightness, the lightness-size illusion was observed, i.e., the darker circle was perceived to be smaller. However, after experimental subjects were shown a large, light circle and a smaller, darker circle repeatedly, the subjective size of the dark circle increased. It decreased after repeated exposures to a small, light circle and a large, dark one. These changes in perception were assumed to be contrast effects produced by an experimentally fixed set and were similar to changes observed when the same method was previously applied by this author to the size-weight illusion. Despite differences in modality and dimension of perception, every application of the fixed-set method resulted in analogous patterns. When the situation of the set-fixing experiment and that of the critical experiment were similar to each other, the fixed set was activated more and greater contrast effects were produced. 相似文献

The Portrait Values Questionnaire (PVQ) is a widely used questionnaire for assessing sense of values; however, it is difficult to apply for children and adolescents. Therefore, the present study aimed to develop a questionnaire for sense of values, called the Brief Personal Values Inventory (BPVI), consisting of simple questions and fewer items compared to the PVQ. We first created 12 items for the BPVI and then tested criterion-related validity with values in the PVQ-57 in 167 Japanese general population participants (81 males, mean age [SD], range: 23.4 [8.2], 15–57 years). Each of these items was correlated with one or more of the values in the PVQ-57 and covered all higher-order values in Schwartz's theory (openness to change, self-enhancement, conservation, and self-transcendence). In summary, the BPVI adequately corresponded with Schwartz's value theory, indicating an acceptable criterion-related validity. This questionnaire is applicable to a wide population, including adolescents, and will be a useful tool for researchers to elucidate the developmental pathway of personal sense of values. 相似文献
