Introduction:To limit the spread of COVID-19, many countries, including Belgium, have installed physical distancing measures. Yet, adherence to these newly installed behavioral measures has been described as challenging and effortful. Based on the Health Action Process Approach (HAPA) model, this study performed an in-depth evaluation of when, why, and how people deviated from the physical distancing measures.Methods:An online mixed-method study was conducted among Belgian adults (N = 2055) in the beginning of May 2020. Participants were recruited via an open call through email and social media platforms, using snowball sampling. Conditions wherein people deviated from the physical distancing measures were assessed by means of an open-ended question. HAPA determinants were assessed in a quantitative way.Results:Half of the sample reported to deviate from the measures. Further, deviation from the measures was associated with each determinant outlined by the HAPA. Findings highlight that many people deviated from the measures because of their need for social contact. The majority of the people who deviated from the measures stated that they carefully weighed the risks of their behavior.Conclusions:Need for social contact pushed people to deviate from physical distancing measures in a deliberate manner. Potential areas for future interventions aimed at promoting adherence to physical distancing measures and enhancing psychosocial well-being are discussed. 相似文献

Reactions to group success and failure as a function of identification level: a test of the goal-transformation hypothesis in social dilemmas 总被引:1,自引:0,他引:1
This study examined the combined effects of identification level, social value orientation, and feedback on contributions in a public goods dilemma. Previous research has shown that strengthening group identity promotes cooperation. One explanation for this finding is that a strong group identity transforms people's motives from the personal to the collective level (the goal transformation hypothesis). Evidence for this hypothesis can be found in studies showing that a strong sense of group identity influences proselfs, relative to prosocials, to make larger contributions. In this experiment, we demonstrated that these findings are restricted to situations in which no feedback about a group's performance is provided. When performance feedback is provided, a strong group identity cancels the effects of individual differences in social value orientations. In particular, when a group fails, contributions increase if group identity is salient, but decrease if personal identity is salient, regardless of a person's social value orientation. But when a group succeeds, no differences between group and personal identity are found. These results are discussed in terms of the goal transformation hypothesis. 相似文献

Two experiments investigated how leadership shapes individual contributions in small groups facing public goods dilemmas. We predicted that the influence of leaders would be determined by their ability to fulfill both instrumental needs (solve the free-rider problem) and relational needs (contribute to the identity) of group members. The relative importance of these two needs was expected to vary with the salience of group membership (social vs personal identity). This hypothesis was supported in two experiments. Experiment 1 revealed that leaders showing group commitment and fairness toward members were more effective at raising contributions when social identity was salient. Furthermore, Experiment 2 showed that highly committed leaders were more influential when social identity was salient, whereas leaders with intrinsic leadership skills were more influential when personal identity was salient. This suggests that the effectiveness of leader solutions to social dilemmas depends upon the fit between leader characteristics and member expectations. 相似文献

This paper presents an analysis of the distribution of phonological similarity relations among monosyllabic spoken words in English. It differs from classical analyses of phonological neighborhood density (e.g., Luce &; Pisoni, 1998) by assuming that not all phonological neighbors are equal. Rather, it is assumed that the phonological lexicon has psycholinguistic structure. Accordingly, in addition to considering thenumber of phonological neighbors for any given word, it becomes important to consider thenature of these neighbors. If one type of neighbor is more dominant, neighborhood density effects may reflect levels of segmental representation other than the phoneme, particularly prior to literacy. Statistical analyses of the nature of phonological neighborhoods in terms ofrime neighbors (e.g.,hat/cat),consonant neighbors (e.g.,hat/hit), andlead neighbors (e.g.,hat/ham) were thus performed for all monosyllabic words in the Celex corpus (4,086 words). Our results show that most phonological neighbors are rime neighbors (e.g.,hat/cat) in English. Similar patterns were found when a corpus of words for which age-of-acquisition ratings were available was analyzed. The resultant database can be used as a tool for controlling and selecting stimuli when the role of lexical neighborhoods in phonological development and speech processing is examined. 相似文献

The dual‐task paradigm was used to show how visuospatial working memory and the phonological loop are involved in processing scientific texts and illustrations presented via computer. In experiment 1, two presentation formats were compared: text‐only and text‐with‐illustrations. With a concurrent tapping task, the beneficial effect of illustrations disappeared, while a concurrent articulatory task impaired performance similarly in both presentation formats. An analysis of individual differences revealed that this pattern of results was present in high, but not low spatial span subjects. These results support the selective involvement of visuospatial working memory in processing illustrated texts. In Experiment 2, the text‐only presentation format was compared to an illustrations‐only format. The concurrent articulatory task selectively impaired text‐only processing, compared with processing illustrations‐only. In addition, this pattern of results was found for high, but not low digit span subjects. These results suggest that individual differences define the extent to which the two subsystems of working memory are involved in learning from multimedia. These two subsystems would be mainly involved in the maintenance of a visual trace of illustrations and of a verbatim representation of linguistic information respectively, these representations being the basis for higher‐level comprehension processes.

Research into adults' recall from different presentation modalities has demonstrated a recall advantage for print over television yet recent research indicates that children remember television news better than print news. An experiment was conducted by comparing children's and adults' recall of children's news stories presented in two different modalities, television and print, in order to establish whether children's recall advantage for television is dependent on their age or level of reading proficiency. A sample of 40 adults, 40 13‐year‐olds and 40 11‐year‐olds were presented with children's news stories, either in their original televised form or in a print version. All participants were aware they would be tested for recall. The results of the cued recall test indicated that children from both age groups learned more from the television news than from the print versions, regardless of age or reading proficiency and that adults remembered equal amounts from both presentation modalities. For the 11‐year‐olds the advantage of television was only found for information that had been accompanied by redundant pictures in the televised version, providing support for the dual‐coding hypothesis. For 13‐year‐olds the recall of television was not dependent on the addition of redundant visual information. Viewers and readers were found to invest the same amounts of mental effort, but reported levels of invested mental effort were found to be dependent on age and level of reading proficiency.

This study examined the interactive effects of task structure, decision rule, and social motive on small-group negotiation processes and outcomes. Three-person groups negotiated either within an asymmetrical task structure (in which a majority of group members have compatible interests) or within a symmetrical task structure (in which no such majority exists). Groups negotiated either under unanimity rule or under majority rule, and group members were either egoistically or prosocially motivated. Results revealed cumulative main effects and the predicted three-way interaction: Groups in an asymmetrical task structure engaged in more distributive and less integrative behavior, reached lower joint outcomes, and experienced a less positive group climate especially when they had an egoistic rather than prosocial motivation and unanimity rather than majority rule applied. Theoretical implications and avenues for future research are discussed. 相似文献

The current study first longitudinally examines the validity of person-environment (P-E) RIASEC congruence, adopting a job analytic method to assess the environment and using P-E difference scores to compute congruence, to predict a range of intrinsic career outcomes—including job satisfaction, skill development, work involvement, and perceived stress—in a sample of 401 college seniors involved in the labor market. Second, the incremental validity of an alternative conceptualization of the P component (i.e., the Five-Factor Model of personality [FFM]) is examined over and beyond RIASEC congruence scores. Congruence across RIASEC types significantly predicted job satisfaction and skill development, but FFM traits significantly and substantially contributed to the prediction of all intrinsic career outcomes. Finally, a person-centered perspective to P-E questions is introduced, demonstrating that cluster analysis of individuals' FFM scores resulted in two clusters (i.e., internalizers/externalizers and resilients) showing very different positions on the labor market and reporting differing initial career outcomes. It is concluded that RIASEC P-E fit congruence studies should be complemented with FFM assessment to increase predictive validity. Applications of an FFM-based, person-centered approach in I/O and P-E fit research and practice are discussed. 相似文献
