Understanding the foot‐in‐the‐door effect as a pseudo‐effect from the perspective of the Campbell paradigm 下载免费PDF全文
Compliance with a small request (a metaphorical foot‐in‐the‐door) promotes compliance with a subsequent big request. Whereas some explanations expect a drop in the behavioural costs of the big request, others suspect that the effect comes from boosting the underlying attitude. However, evidence for both explanations is equivocal and circumstantial, at best. Drawing on what Kaiser et al. (2010) call the Campbell paradigm, we present an integrative account: Compliance with any request demands a corresponding attitude to counterbalance the costs of the request. In our research, 229 participants were randomly assigned to either a foot‐in‐the‐door (i.e., initially asked to sign a pro‐environmental petition) or a control condition. Small‐request‐compliant participants were more likely than control participants to also comply with the big request and to continue filling out environmental‐issues‐related questionnaires. However, this foot‐in‐the‐door effect occurred without diminishing behavioural costs or increasing attitude levels. Accordingly, the greater likelihood of small‐request‐compliant participants to also comply with the big request can be parsimoniously explained by baseline variability in people's attitude levels that manifests in their compliance with the initial request. We conclude that several of the foot‐in‐the‐door effects reported in the literature carry the risk of representing mere pseudo‐effects. 相似文献

In comparing characteristics of independent populations, researchers frequently expect a certain structure of the population variances. These expectations can be formulated as hypotheses with equality and/or inequality constraints on the variances. In this article, we consider the Bayes factor for testing such (in)equality-constrained hypotheses on variances. Application of Bayes factors requires specification of a prior under every hypothesis to be tested. However, specifying subjective priors for variances based on prior information is a difficult task. We therefore consider so-called automatic or default Bayes factors. These methods avoid the need for the user to specify priors by using information from the sample data. We present three automatic Bayes factors for testing variances. The first is a Bayes factor with equal priors on all variances, where the priors are specified automatically using a small share of the information in the sample data. The second is the fractional Bayes factor, where a fraction of the likelihood is used for automatic prior specification. The third is an adjustment of the fractional Bayes factor such that the parsimony of inequality-constrained hypotheses is properly taken into account. The Bayes factors are evaluated by investigating different properties such as information consistency and large sample consistency. Based on this evaluation, it is concluded that the adjusted fractional Bayes factor is generally recommendable for testing equality- and inequality-constrained hypotheses on variances. 相似文献

Organizations in the twenty-first century face the challenges of an increasingly ageing workforce, which have an effect on organizational health and productivity. As chronological age has shown to be an insufficient indicator of employees’ health and, in particular, absenteeism, we apply the subjective age concept (i.e., how old an employee feels) at the team-level to explain the average chronological age/average short-term absenteeism relationship. We develop a theoretical framework for underlying processes, combining the subjective age research with the socioemotional selectivity theory and team contagion processes. We test our predictions in a time-lagged team-level sample of 1,015 teams with 12,926 employees to find a significant interactive effect of average chronological age and average subjective age on average short-term absenteeism in teams. The relationship is negative and significant when average subjective age is low. Under high-average subjective age, the relationship is non-significant. Furthermore, this interactive effect (average chronological age/average subjective age) is moderated by job type (white versus blue collar) in the form of a three-way interaction, indicating that the effect is only significant among white collar teams. We hope to enrich the theoretical debate on age and absenteeism and provide organizations with a new perspective on ageing work teams. 相似文献

This paper reports an experimental investigation of presuppositions and scalar implicatures in language acquisition. Recent proposals (Chemla 2009; Romoli 2012, Romoli in J Semant 1–47, 2014) posit the same mechanisms for generating both types of inferences, in contrast to the traditional view. We used a Covered Box picture selection task to compare the interpretations assigned by two groups of children (4/5 and 7 year olds) and by adults, in response to sentences with presuppositions and ones with either ‘direct’ or ‘indirect’ scalar implicatures. The main finding was that the behavior of children and adults differed across inference types. This asymmetry is consistent with the traditional perspective, but poses a challenge for the more recent uniform accounts. We discuss how the latter could be amended to account for these findings, and also relate the findings to previous results on presupposition processing. Finally, we discuss an unexpected difference found between direct and indirect scalar implicatures. 相似文献

The capability of the human brain for Bayesian inference was assessed by manipulating probabilistic contingencies in an urn-ball task. Event-related potentials (ERPs) were recorded in response to stimuli that differed in their relative frequency of occurrence (.18 to .82). A veraged ERPs with sufficient signal-to-noise ratio (relative frequency of occurrence > .5) were used for further analysis. Research hypotheses about relationships between probabilistic contingencies and ERP amplitude variations were formalized as (in-)equality constrained hypotheses. Conducting Bayesian model comparisons, we found that manipulations of prior probabilities and likelihoods were associated with separately modifiable and distinct ERP responses. P3a amplitudes were sensitive to the degree of prior certainty such that higher prior probabilities were related to larger frontally distributed P3a waves. P3b amplitudes were sensitive to the degree of likelihood certainty such that lower likelihoods were associated with larger parietally distributed P3b waves. These ERP data suggest that these antecedents of Bayesian inference (prior probabilities and likelihoods) are coded by the human brain. 相似文献

The increasing availability of high-dimensional, fine-grained data about human behaviour, gathered from mobile sensing studies and in the form of digital footprints, is poised to drastically alter the way personality psychologists perform research and undertake personality assessment. These new kinds and quantities of data raise important questions about how to analyse the data and interpret the results appropriately. Machine learning models are well suited to these kinds of data, allowing researchers to model highly complex relationships and to evaluate the generalizability and robustness of their results using resampling methods. The correct usage of machine learning models requires specialized methodological training that considers issues specific to this type of modelling. Here, we first provide a brief overview of past studies using machine learning in personality psychology. Second, we illustrate the main challenges that researchers face when building, interpreting, and validating machine learning models. Third, we discuss the evaluation of personality scales, derived using machine learning methods. Fourth, we highlight some key issues that arise from the use of latent variables in the modelling process. We conclude with an outlook on the future role of machine learning models in personality research and assessment. 相似文献

Five studies examined the contribution of attachment style to mortality salience effects. In Study 1, mortality salience led to more severe judgments of transgressions only among anxious-ambivalent and avoidant persons but not among secure persons. In addition, whereas anxious-ambivalent persons showed immediate and delayed increases in severity judgments, avoidant persons showed this response only after a delay period. In Study 2, anxious-ambivalent persons showed immediate and delayed increases in death-thought accessibility after death reminders. Avoidant and secure persons showed this effect only after a delay period. Study 3 revealed that worldview defense in response to mortality salience reduced death-thought accessibility only among avoidant persons. Studies 4-5 revealed that mortality salience led to an increase in the sense of symbolic immortality as well as in the desire of intimacy only among secure persons, but not among avoidant and anxious-ambivalent persons. 相似文献

Team performance and coordination have gained considerable interest in disparate fields (e.g., aviation, process control, medicine, and wartime operations). Team-Track, a C program that allows controlled experimental manipulation of team conditions, was developed to meet the research needs resulting from this interest. Using Team-Track, one can manipulate task interdependence, team staffing, relative contributions of team members, communications, and informational displays in a low-cost environment. The dependent measure of performance generated by the program is the absolute tracking error along each dimension. The program is ideal for investigating team interactions as it allows for orthogonal manipulation of team variables, therefore accommodating a multitude of research paradigms. 相似文献

The present study investigated adolescents' perception of closeness to their parents and family rules restricting their conduct, in Arab and Jewish Israeli samples. A total of 854 11th-grade high school students reported their perceptions by a self-report questionnaire. Overall, the results indicate that the Arab youths perceived more closeness toward their parents and more rules restricting their conduct, compared with their Jewish counterparts. In both cultures, girls reported more restrictions on dating and leaving home than boys. Among Israeli Arab adolescents a positive association was uncovered between closeness to parents and number of rules. No such pattern was evident among Israeli Jewish youth. These and additional findings are discussed within the context of Triandis' cross-cultural dimension of collectivism-individualism. 相似文献
