The Role of Domain-Specific Knowledge in Generative Reasoning About Complicated Multileveled Phenomena

Promoting the ability to reason generatively about novel phenomena and problems students may encounter in their everyday lives is a major goal of science education. This goal proves to be a formidable challenge in domains, such as molecular genetics, for which the accumulated scientific understandings are daunting in both amount and complexity. To develop effective instruction that fosters generative reasoning we need to have a sound understanding of the types of knowledge in the domain that are critical for such reasoning. In this study I examined the ensemble of knowledge, both general and domain-specific, undergraduate students employed in reasoning about problems in genetics. I found that students initially formulate a solution in terms that are not domain specific and that serve as a frame–solution frame–that outlines and constrains a more specific and domain-appropriate explanation. This solution frame is then filled in with two powerful forms of domain-specific knowledge I term: domain-specific heuristics and domain-specific explanatory schemas. These knowledge forms embody understandings of central mechanisms and entities in molecular genetics. By invoking these domain-specific knowledge forms, students were able to reason about a variety of both familiar and novel genetics problems. I present a cognitive model that highlights the role of these powerful conceptual understandings in promoting generative reasoning in genetics.     

The Process of Personal Change Through Reading Fictional Narratives: Implications for Psychotherapy Practice and Theory

This qualitative study provides an understanding of how and when individuals experience transformational change as a consequence of reading narratives. Six participants who attributed significant personal changes to reading were recruited and interviewed. The investigators used grounded theory method to analyze these interviews and identify processes through which change unfolded. The core category of the analysis was identification with characters' experiences created a safe venue to consider threat and experiment with new possibilities and perspectives. Empathizing with protagonists enabled readers to integrate new modes of responding to personally difficult situations. Implications for bibliotherapy and narrative therapy are discussed.     

A Meta-Analysis of the Relationship Between Rater Liking and Performance Ratings

This meta-analysis reviewed the magnitude and moderators of the relationship between rater liking and performance ratings. The results revealed substantial overlap between rater liking and performance ratings (ρ = .77). Although this relationship is often interpreted as indicative of bias, we review studies that indicate that to some extent the relationship between liking and performance ratings potentially reflects “true” differences in ratee performance. Moderator analyses indicated that the relationship between liking and performance ratings was weaker for ratings of organizational citizenship behaviors, ratings made by peer raters, ratings in nonsales jobs, and ratings made for development; however, the relationship was strong across moderator levels, underscoring the robustness of this relationship. Implications for the interpretation of performance ratings are discussed.     

Pre-Entry Expectations,Attitudes, and Intentions to Join Predict Military Tenure

The objective of this study was to examine pre-entry expectations, attitudes, and intentions as predictors of tenure among military members. Data from nationally representative (U.S.) samples of youth on attitudes toward military service, expectations about the effect of joining the military on quality of life, and intentions to join the military were linked to tenure among those who later joined the military as adults. Results from survival analyses indicate that those who initially had no desire to join the military and did not expect military service to have positive effects on their quality of life, but ultimately joined the military nonetheless, tended to have shorter military careers. Explanations for these findings are offered along with implications for military staffing.     

Superdupersizing the mind: extended cognition and the persistence of cognitive bloat

The hypothesis of extended cognition (EC) contends that parts of the world outside of the head partly comprise the vehicles of representation and mind. I consider and reject recent efforts to defend EC from the problem of “cognitive bloat.”     

Through hermeneutics of suspicion to a rediscovery of faith

Ric?ur argued that the critique of religion developed by the three modern masters of a hermeneutics of suspicion – Marx, Nietzsche, and Freud – is liberating insofar as it makes possible a mature faith. In the first part of the article, I explore this issue in relation to Kierkegaard. In the second part of the article, I discuss how Kierkegaard uses a biblical critique of religion, particularly the figure of the prophet, in his final attack on the church in his pamphlet “What Christ Judges of Official Christianity”. Through my investigation of the role of a hermeneutics of suspicion in Kierkegaard’s rediscovery of faith, I aim to question Ric?ur’s dichotomy between an external, atheistic hermeneutics of suspicion versus an internal hermeneutics of faith.     

Regulating self-defensiveness: If–then plans prevent claiming and creating performance handicaps

Claiming or creating obstacles before performing important tasks (i.e., self-handicapping) is a costly strategy to protect the self from implications of poor outcomes. We predicted that forming an if–then plan (implementation intention) helps individuals overcome their performance-related worries and thus prevents self-handicapping behavior. In two experiments, all participants formed the goal to perform well on an upcoming task and learned the strategies to ignore worries and tell themselves “I can do it”, either in an if–then format (implementation intention) or not (control). The task was either described as an intelligence test (highly threatening) or as a perception style test (less threatening). Participants could then claim a self-handicap (report stress, Experiment 1) or behaviorally self-handicap (inadequately prepare, Experiment 2). As predicted, implementation intentions reduced claimed and behavioral self-handicapping to levels observed in the low-threat control conditions. Experiment 2 demonstrated these effects among chronic self-handicappers. Implications of these findings are discussed.     

Validation of a new multidimensional health locus of control scale (form c) in asthma research

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.     

Exercise environment,self-efficacy,and affective responses to acute exercise in older adults

Abstract

Increasing evidence suggests that regular physical activity can have considerable psychological, as well as physical, benefits in the elderly. Although factors such as exercise dosage may be implicated in exercise-induced affect responses, it has also been suggested that social and psychological factors might influence this relationship. This study examined the roles played by exercise environment (group versus alone) and self-efficacy in affective change in 80 older adults (M age = 66 yrs) over the course of three acute exercise bouts. Using latent growth curve methodology and statistically controlling for duration and intensity of exercise, we were able to demonstrate that social (group) environments resulted in statistically significant improvements in feeling state responses when contrasted with a condition in which the participants exercised alone. In addition, increases in self-efficacy were associated with more positive and less negative feeling states. Environmental factors that might influence the exercise-affect response are discussed and recommendations for subsequent exercise, efficacy, affect research made.
