Computer programs for statistical power analysis typically require the user to provide a series of values and respond by reporting the corresponding power. These programs provide essentially the same functions as a published text, albeit in a more convenient form. In this paper, we describe a program that instead uses innovative graphic techniques to provide insight into the interaction among the factors that determine power. For example, fort tests, the means and standard deviations of the two distributions, sample sizes, and alpha are displayed as bar graphs. As the researcher modifies these values, the corresponding values of beta (also displayed as a bar graph) and power are updated and displayed immediately. By displaying all of the factors that are instrumental in determining power, the program ensures that each will be addressed By allowing the user to determine the impact that any modifications will have on power, the program encourages an appropriate balance between alpha and beta while working within the constraints imposed by a limited sample size. The program also allows the user to generate tables and graphs to document the impact of the various factors on power. In addition, the program enables the user to run on-screen Monte Carlo simulations to demonstrate the importance of adequate statistical power, and as such, it can serve as a unique educational tool. 相似文献

Laboratory tests of event-based prospective memory (ProM) require participants to perform actions in response to infrequent
cues in a background task. We conducted three experiments to assess and improve the reliability of this popular procedure.
In Experiment 1, we tested college students on 2 separate days and found that the alternate-forms reliability of ProM accuracy
was quite low (r = .31), although general knowledge accuracy was more reliable (r= .89). In Experiment 2, a statistically significant difference in reliability emerged between conditions with a low (n = 6) versus a high (n = 30) number of ProM targets. Finally, lower ProM accuracy increased reliability in Experiment 3. Adopting these straightforward
changes may enhance the search for individual differences in ProM. 相似文献

Classification "rules" in expert and everyday discourse are usually deficient by formal standards, lacking explicit decision procedures and precise terms. The authors argue that a central function of such weak rules is to focus on perceptual learning rather than to provide definitions. In 5 experiments, transfer following learning of family resemblance categories was influenced more by familiar-appearing features than by novel-appearing features equally acceptable under the rule. This occurred both when rules were induced and when rules were given at the beginning of instruction. To model this and other phenomena in categorization, features must be represented on 2 levels: informational and instantiated. These 2 feature levels are crucial to provide broad generalization while reflecting the known peculiarities of a complex world. 相似文献

This paper develops the concept of implicit trait policy (ITP), which is a variant of the accentuation effect described by Tajfel (1957). ITPs are implicit beliefs about causal relations between personality traits and behavioral effectiveness. Studies reported here tested the hypotheses (a) that personality traits affect ITPs so that agreeable people, for instance, believe the relation between agreeableness and effectiveness is more strongly positive than disagreeable people do and (b) that ITPs can predict behavior that expresses associated personality traits. Two studies with undergraduate research participants supported the first hypothesis for traits of agreeableness and extraversion (the average correlation between traits and associated ITPs was .31 for agreeableness and .37 for extraversion) but not for conscientiousness. A 3rd study with student participants found that individual differences in ITPs for agreeableness predicted agreeable behavior (the average correlation was .33) in simulated work settings. These results suggest that ITPs may be useful for predicting work behavior that expresses personality traits even though ITPs may not be strongly correlated with the personality traits themselves. 相似文献

Job comparison research is critical to many human resources initiatives, such as transporting validity evidence. Job analysis methods often focus on critical attribute (e.g., tasks, work behaviors) overlap when assessing similarity, but profile similarity metrics represent an alternative or complementary approach for job comparisons. This paper utilizes Occupational Information Network (O*NET) data to establish a distribution of job profile correlations across all job pairs for five attributes – generalized work activities, knowledge, skills, abilities, and work styles. These correlations represent effect sizes, or degree of shared variance between jobs. Practitioners may reference these correlational distributions as benchmarks for gauging the practical significance of the observed degree of similarity between two jobs of interest compared to the broader world of work. 相似文献

Childhood experiences and impressions are important for individuals' health and well-being—they often set the stage for how people approach relationships across the lifespan and how they make sense of their relational worlds. However, impressions of these experiences are likely not static and can change over time, even years after these experiences happened. The current study examined how impressions of parental relationships in childhood changed over time, and predictors of these changes, among middle-aged and older adults followed over a 4-year period (N = 2692; Mage = 66.67, SD = 9.15; 64.1% women). Childhood impressions of parental care were mostly stable over time, with 53.5%–65.0% of participants reporting consistent impressions. Becoming divorced/separated as an adult was associated with more negative impressions about relationships with fathers in the past. Having a mother pass away was associated with more positive impressions of mothers' caregiving when participants were children. Higher depressive symptoms at follow-up were associated with darker perceptions of the past—more negative impressions of mothers and fathers as caregivers. The current study is one of the most comprehensive studies of late-life changes in childhood impressions to date, suggesting future directions for studying the organization of relational experiences and recollection over time. 相似文献

Proponents of manipulation arguments against compatibilism hold that manipulation scope (how many agents are manipulated) and manipulation type (whether the manipulator intends that an agent perform a particular action) do not impact judgments about free will and moral responsibility. Many opponents of manipulation arguments agree that manipulation scope has no impact but hold that manipulation type does. Recent work by Latham and Tierney (2022, 2023) found that people's judgments were sensitive to manipulation scope: people judged that an agent was less free and responsible when a manipulation was existential (impacting at least one but not all agents) than when the manipulation was universal (impacting every agent). This study examines people's judgements about existential and universal manipulation cases that involve both intentional and non-intentional outcomes. We found that manipulation scope also affects people's free will and responsibility judgments in manipulation cases involving both intentional and non-intentional outcomes. Interestingly, we also found that manipulation type influences the effect that manipulation scope has on people's free will judgments but not their moral responsibility judgments, which indicates that people's free will and responsibility judgments can come apart. This puts pressure on the prevalent assumption that judgments about free will and moral responsibility are conceptually bound together. 相似文献

This study examined predictors of single people's beliefs about COVID prevention behaviors, intentions to engage in COVID prevention behaviors while dating, and actual dating behavior during the pandemic. Results revealed that single participants engaged in “riskier” dating behaviors (i.e., in-person unmasked) more frequently than “safer” dating behaviors (i.e., remote, or in-person masked/distanced). Individuals who perceived greater (vs. lesser) risk associated with COVID more strongly endorsed beliefs about social distancing (self and other) and were more likely to personally (or request others) engage in COVID prevention behaviors while dating. However, perceived risk did not predict actual dating behaviors. Conservatives (vs. liberals) less strongly endorsed beliefs about social distancing (for others, but not the self) and were less likely to personally (or request others) engage in COVID prevention behaviors while dating. Conservatives also reported meeting potential romantic partners more frequently than liberals. However, political ideology did not predict actual dating behaviors. Results suggest there is a disconnect between college students' beliefs/intentions and their actual dating behavior. These results demonstrate the importance of developing public health interventions that take into account the disconnect between college students' health-related intentions and actual behaviors, particularly in the context of dating. 相似文献
