Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19. 相似文献

Visual orientation during lateral tilt is viewed in terms of orientation constancy. The postural systems involved in the maintenance of constancy are considered to be those of the otolith, neck and trunk. The relative contribution of these systems was investigated by obtaining visual verticality judgments immediately upon and several minutes after head, body, and trunk tilts. Due to the apparent non-adaptation of the otolith system any changes in visual orientation resulting from prolonged tilt would be attributed to adaptation of the proprioceptive system stimulated. For 30° head tilt visual orientation over-constancy was reduced by about 2°, reflecting the influence of the neck system. Prolonged body tilts of 30°, 60° and 90° reduced the constancy operating by approximately 1°, 3° and 8°, respectively. This was taken to indicate the contribution of the trunk system, which increased with increasing degrees of body tilt. The above interpretations received strong support from experiments involving trunk tilt, which stimulates only the neck and trunk systems. 相似文献

A major deduction of the drive-reduction hypothesis of reinforcement was tested. A light which follows the termination of a shock coincides with a condition of drive or need reduction. If drive reduction is a sufficient condition for reinforcement, then the light should become a secondary reinforcing agent by virtue of its association with the drive-reduction event. If it becomes a secondary reinforcing agent, it should be able to reinforce an instrumental act.
This sequence of deductions was tested by placing rats in a stock, giving them a brief shock upon the termination of which a light was flashed for one second. After sixty such pairings, subjects were then placed in a Skinner box under operant test conditions; when they pressed the bar a light flashed on.
Animals subjected to this training programme were compared for rate of bar pressing with animals subjected to a variety of control conditions. No significant differences were found among the groups, and it was concluded that in so far as the deductions from drive-reduction theory were correct, the theory was not substantiated. The paper concludes with a discussion of various problems which might limit the interpretation of the experimental results. 相似文献

Summary The study of stereopsis, made possible by the invention of the stereoscope, freed binocular vision from the yoke of monocular phenomena. Wheatstone used this freedom to determine the factors involved in the perception of size and distance, and interpreted them within a cognitive framework. He devised an adjustable stereoscope which allowed him to apply the systematic experimental procedures of physics to the phenomena of depth perception. Brewster, by contrast, tried to force the newly discovered binocular phenomena back into the mould of monocular vision, using the lever of visible direction. His interpretations of visual phenomena, be they monocular or binocular, could be reduced to the two fundamental laws of visible direction and distinct vision. While Wheatstone's cognitive approach influenced Helmholtz, and thereby modern cognitive theorists. Brewster's interpretations, based as they were in analyses of the retinal projection, find an echo in modern direct theorists. 相似文献

This research assessed factors that may affect men’s heterosexual romantic relationships in which their partner earns a greater income. Forty-seven men from the United States completed measures that assessed masculinity ideology, the importance of the partner’s greater income, and romantic relationship quality. We examined whether the perceived importance of the income disparity mediated the relationship between men’s masculinity ideology and the quality of their romantic relationships. Using multiple regression analyses to test for mediation, results showed the relationship between masculinity ideology and romantic relationship quality was due in part to the importance one placed on the difference in income. Specifically, men who were more traditional in their masculinity ideology and have higher earning female partners were more likely to have poor quality romantic relationships in part because such men view the disparity in income as having importance. Conversely, results showed men who were more nontraditional in their masculinity were more likely to perceive the disparity in income as having little or no importance and have high romantic relationship quality. 相似文献

Because memories are not always accurate, people rely on a variety of strategies to verify whether the events that they remember really did occur. Several studies have examined which strategies people tend to use, but none to date has asked why people opt for certain strategies over others. Here we examined the extent to which people's beliefs about the reliability and the cost of different strategies would determine their strategy selection. Subjects described a childhood memory and then suggested strategies they might use to verify the accuracy of that memory. Next, they rated the reliability and cost of each strategy, and the likelihood that they might use it. Reliability and cost each predicted strategy selection, but a combination of the two ratings provided even greater predictive value. Cost was significantly more influential than reliability, which suggests that a tendency to seek and to value “cheap” information more than reliable information could underlie many real-world memory errors. 相似文献

Maximising dissemination of efficacious psychological interventions is an important undertaking, particularly in prevention work where the target population may not be seeking help. Consequently, the current study investigated voluntary participation in a selective eating disorder prevention programme by examining predictors of, and evaluating a motivational enhancement approach to, increased participation. Female students studying first-year psychology (N = 124, Mage = 19.30, SD = 1.55) completed baseline measures, were randomised to a motivational or control condition, then presented with a flyer for an eating disorders prevention trial and assessed regarding potential participation. Results showed that interest and likelihood of participation were low overall and lack of time the most commonly endorsed reason. Participants high on weight concerns were more likely to cite the group format of the intervention as a deterrent. A greater belief in the helpfulness of body image programmes and higher personal ineffectiveness were significant predictors of interest in participation. There was no significant difference between those who did and did not undergo the motivational enhancement with respect to interest and likelihood of participation. These findings suggest important avenues for consideration when designing eating disorder prevention efforts relying on voluntary participation, and highlight the importance of evaluating programmes cross-culturally. 相似文献

The prevalence and correlates of depressive symptoms following childhood traumatic brain injuries (TBI) were examined using data drawn from a prospective longitudinal study. Participants included 38 children with severe TBI, 51 with moderate TBI, and 55 with orthopedic injuries (OI). Assessments occurred shortly after injury (baseline) and at 6- and 12-month follow-ups. Children completed the Child Depression Inventory (CDI). Parents rated depressive symptoms using the Child Behavior Checklist (CBC), with baseline ratings reflecting premorbid status. Assessments also included measures of children's neurocognitive functioning and the family environment. The three groups did not differ overall in self-reported symptoms on the CDI, but did display different trends over time. The three groups did not differ on parent ratings of premorbid depressive symptoms on the CBC, but parents reported more depressive symptoms in the TBI groups than in the OI group at 6- and 12-month follow-ups. Child and parent reports were correlated for children in the TBI groups, but not for those in the OI group. Depressive symptoms were related to socioeconomic status in all groups. Socioeconomic status also was a significant moderator of group differences, such that the effects of TBI were exacerbated in children from more disadvantaged homes. Although self-reports of depressive symptoms were related inconsistently to children's verbal memory, parent reports of depressive symptoms were unrelated to IQ or verbal memory. The findings suggest that TBI increases the risk of depressive symptoms, especially among more socially disadvantaged children, and that depressive symptoms are not strongly related to post-injury neurocognitive deficits. 相似文献

This paper presents recent research that provides an overarching model of exemplar theory capable of explaining phenomena across the phonetic and syntactic strata. The model represents a unique exemplar-based account of constituency interactions encompassing both linguistic domains. It yields simulation and experimental results in keeping with experimental findings in the literature on syllable duration variability and offers an exemplar-theoretic account of local grammaticality. In addition, it provides some insights into the nature of exemplar cloud formation and demonstrates experimentally the potential gains that can be enjoyed via the use of rich exemplar representations. 相似文献
