Salience Versus Proportional Reasoning: Rethinking the Mechanism Behind Graphical Display Effects

Two experiments examined predictions from two separate explanations for previously observed display effects for communicating low‐probability risks: foreground:background salience and proportional reasoning. According to foreground:background salience, people's risk perceptions are based on the relative salience of the foreground (number of people harmed) versus the background (number of people at risk), such that calling attention to the background makes the risk seem smaller. Conversely, the proportional reasoning explanation states that what matters is whether the respondent attends to the proportion, which conveys how small the risk is. In Experiment 1, we made the background more salient via color and bolding; in contrast to the foreground:background salience prediction, this manipulation did not influence participants' risk aversion. In Experiment 2, we separately manipulated whether the foreground and the background were displayed graphically or numerically. In keeping with the proportional reasoning hypothesis, there was an interaction whereby participants given formats that displayed the foreground and background in the same modality (graphs or numbers, thereby making the proportion easier to form) saw the probability as smaller and were less risk averse than participants given the information in different modalities. There was also a main effect of displaying the background graphically, providing some support for foreground:background salience. In total, this work suggests that the proportional reasoning account provides a good explanation of many display effects related to communicating low‐probability risks, although there is some role for foreground:background salience as well.

Learning progressions have been demarcated by some for science education, or only concerned with levels of sophistication in student thinking as determined by logical analyses of the discipline. We take the stance that learning progressions can be leveraged in mathematics education as a form of curriculum research that advances a linked understanding of students learning over time through careful articulation of a curricular framework and progression, instructional sequence, assessments, and levels of sophistication in student learning. Under this broadened conceptualization, we advance a methodology for developing and validating learning progressions, and advance several design considerations that can guide research concerned with engendering forms of mathematics learning, and curricular and instructional support for that learning. We advance a two-phase methodology of (a) research and development, and (b) testing and revision. Each phase involves iterative cycles of design and experimentation with the aim of developing a validated learning progression. In particular, we gathered empirical data to revise our hypothesized curricular framework and progression and to measure change in students. thinking over time as a means to validate both the effectiveness of our instructional sequence and of the assessments designed to capture learning. We use the context of early algebra to exemplify our approach to learning progressions in mathematics education with a focus on the concept of mathematical equivalence across Grades 3-5. The domain of work on research on learning over time is evolving; our work contributes a broadened role for learning progressions work in mathematics education research and practice. 相似文献

Theories of boredom assert that boredom is a product of situational meaninglessness. We conducted two studies to test if the perceived meaningfulness of a situation is associated with state boredom, above and beyond sadness, personality traits, and boredom proneness. In Study 1, 105 participants (72.4% female: mean age?=?33.9 years, SD?=?17.5) described situations in which they experienced boredom, no boredom, engagement, or sadness. They then rated the level of state boredom, sadness, and meaninglessness that they experienced in that situation. As hypothesized, state boredom was associated with situational meaninglessness, before and after controlling for sadness. In Study 2, 148 participants (73.0% female; mean age?=?19.2 years, SD?=?1.8) first provided baseline data on personality traits and boredom proneness. Through a smartphone app-based experience-sampling method, they then responded to a brief questionnaire multiple times a day, across 7 days. The questionnaire asked about the nature of their current activity, whether the activity was done alone or with other people, and their affective state. Results from multilevel modelling of 3022 entries suggest that perceived meaningfulness of the activity was negatively associated with state boredom, above and beyond sadness, personality, and boredom proneness. We also found that being with others during the activity acted as a moderator; activities lower in perceived meaningfulness were associated with higher ratings of state boredom when done with others than when done alone. These results demonstrate that perceptions of meaninglessness characterize state boredom. 相似文献

Taking a motivational approach, this study deepens the role of team members’ shared understanding of the work to be done in a project team setting. More specifically, the goal of this study is to test a second stage moderated mediation model in which the mediating role of team members’ proactive behavior in the relationship between perceived shared understanding and team performance is moderated by team adaptability. Based on a multisource and multimethod approach, data were collected from 111 teams of undergraduate and graduate students (521 participants) participating in a project management simulation. Results support the hypothesized moderated mediation model. Indeed, the results indicate that the relationship between perceived shared understanding and team performance is mediated by proactive behavior. The results also show that the relationship between proactive behavior and team performance is moderated by team adaptability. Overall, results reveal that the indirect effect of perceived shared understanding on team performance is moderated by team adaptability, such that this indirect effect is stronger when the level of team adaptability is high. In terms of practical implications, the study highlights the importance of fostering the perception of being “on the same page” in order to motivate members to be proactive and to enhance project team performance. 相似文献

Tool use is typically explored via actor-tool interactions. However, the target-object (that which is being acted on) may influence perceived action possibilities and thereby guide action. Three different tool-target-object pairings were tested (Experiment 1). The hammering action demonstrated the greatest sensitivity and therefore subsequently used to further investigate target-object pairings. The hammer was removed as an option and instructions were provided using pictorial (Experiment 2), written (Experiment 3), and both pictorial and written formats (Experiment 4). The designed tool is chosen when available (Experiment 1) and when removed as a choice (i.e., the hammer), participants perform the same action associated with the designed tool (i.e., hammering) regardless of instruction method (Experiments 2, 3, and 4). 相似文献

Many elementary school students lack school relationships required for positive personal, social, and academic interactions. Reality therapy and play therapy both seek to address these relationships through developmentally appropriate and effective interventions. Integrating these 2 approaches has the potential for elementary school counselors to provide students with opportunities to create positive relationships and develop problem-solving skills. In this study, 8 school counselors participated in a series of trainings introducing reality play-therapy techniques to assess this potential. A thematic analysis conducted on feedback sessions following the trainings yielded themes related to the participants’ positive perceptions to the training and possible application. 相似文献

This study attempted to determine the effects of family and social support on the self‐esteem, self‐efficacy, and job search self‐efficacy of the unemployed. A total of 117 surveys were collected in Nevada, Idaho, and Oregon measuring self‐esteem, general self‐efficacy, and job search self‐efficacy and social support. Pearson correlation coefficients demonstrated moderately strong positive relationships between social support and self‐esteem, general self‐efficacy, and job search self‐efficacy. Social and family support had a stronger influence on the self‐perceptions of men than women. 相似文献
