Several modern accounts of explanation acknowledge the importance of abstraction and idealization for our explanatory practice. However, once we allow a role for abstraction, questions remain. I ask whether the relation between explanations at different theoretical levels should be thought of wholly in terms of abstraction, and argue that changes of the quantities in terms of which we describe a system can lead to novel explanations that are not merely abstractions of some more detailed picture. I use the example of phase transitions as described by statistical mechanics and thermodynamics to illustrate this, and to demonstrate some details of the relationship between abstraction, idealization, and novel explanation. 相似文献

ObjectiveTo review the literature for scientific evidence in support of inclusion of Muscle Dysmorphia (MD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).DesignThe criteria proposed by Blashfield, Sprock, and Fuller (1990) were used for determining whether scientific evidence supports the introduction of MD as a new disorder into a disease classification system.MethodPeer-reviewed journal articles were identified by searching databases for articles published (in print and electronically) from 2001 to 2011.ResultsThe search identified 59 journal articles that specifically focused on MD, of which 39 were empirical journal articles. There is ample literature on MD, including a common set of diagnostic criteria and assessment instruments to measure MD. However, questions remain about the diagnostic reliability and validity, including inter-rater reliability, and whether MD represents a disorder that consists of symptoms that frequently co-occur. Also, evidence of syndrome differentiation is lacking. Only two of the five criteria proposed by Blashfield et al. have been met.ConclusionLiterature suggests that MD is associated with several indicators of clinical significance and distinctiveness. However the current review has found significant limitations and gaps in the scientific literature on MD. Possible options regarding the status of MD in the DSM-5 are proposed, including introducing MD as an example of an eating disorder not otherwise specified, retaining MD as a body dysmorphic disorder, introducing MD as a new disorder, or introducing MD as a provisional diagnosis in need of further study. 相似文献

Physiological arousal, a marker of emotional response, has been demonstrated to accompany human decision making under uncertainty. Anticipatory emotions have been portrayed as basic and rapid evaluations of chosen actions. Instead, could these arousal signals stem from a “cognitive” assessment of value that utilizes the full environment structure, as opposed to merely signaling a coarse, reflexive assessment of the possible consequences of choices? Combining an exploration–exploitation task, computational modeling, and skin conductance measurements, we find that physiological arousal manifests a reflective assessment of the benefit of the chosen action, mirroring observed behavior. Consistent with the level of computational sophistication evident in these signals, a follow-up experiment demonstrates that anticipatory arousal is modulated by current environment volatility, in accordance with the predictions of our computational account. Finally, we examine the cognitive costs of the exploratory choice behavior these arousal signals accompany by manipulating concurrent cognitive demand. Taken together, these results demonstrate that the arousal that accompanies choice under uncertainty arises from a more reflective and “cognitive” assessment of the chosen action’s consequences than has been revealed previously. 相似文献

This paper reports on the development and piloting of the Madres a Madres (Mothers to Mothers) program, a new, community-based parent training program designed for immigrant Latina mothers and their children. Promotoras, or female community health workers of Latina background, delivered the program in a home visitation format. A total of 194 mothers and 194 focal children (87 male, 107 female) ages 7–12 were randomized to the intervention (113 mother–child dyads) or wait-list control condition (81 mother–child dyads) over the study period. Outcomes of interest were mother-reported parenting skills, broad family functioning, and child externalizing and internalizing behaviors. Data collection occurred at pretest, 3-month posttest, and 9-month follow-up periods. Multilevel growth models revealed increases in intervention mothers’ reported parenting skills, family support, and family organization, and reductions in child internalizing behavior from pretest to follow-up, relative to the control condition. Outcomes did not vary by focal child age, gender, nativity status, or mother acculturative status (years in the United States). Findings are discussed in the context of future directions for research on the Madres a Madres program and on the implementation and dissemination of empirically-supported parent training practices to culturally diverse families. 相似文献

A triadic coalition game was structured as an achievement-oriented situation by inclusion of a skill-based game task. Deductions regarding coalition partner choices were derived from Atkinsons' model of achievement motivation with the expectation that achievement-oriented players (Ms < Maf) would prefer moderate-risk strategy options while failure-avoidant players (Maf < Ms) would avoid moderate-risk strategies. Observation was made of the coalition partner preferences of 126 college sophomore males and females who played the game in same-sex triads. The Ss were categorized into motive configuration groups on the basis of scores derived from the Test of Insight and the Test Anxiety Questionnaire. The results were supportive of the hypotheses, since the Ms < Maf group chose moderate-risk coalition options more frequently than did the Maf < Ms group. By contrast the Maf < Ms group chose low-risk strategies and tended to avoid moderate-risk coalition options. While other coalition-game studies have shown differences in strategy behavior between males and females, sex differences did not occur in the present game. The lack of sex differences was explained by the high level of concern for winning among members of both sexes generated by the achievement nature of the game task. 相似文献

Psychotherapy is a conversation, whereby, at its foundation, many interventions are derived from the therapist talking. Research suggests that the voice can convey a variety of emotional and social information, and individuals may change their voice based on the context and content of the conversation (e.g. talking to a baby or delivering difficult news to patients with cancer). As such, therapists may adjust aspects of their voice throughout a therapy session depending on if they are beginning a therapy session and checking in with a client, conducting more therapeutic ‘work’ or ending the session. In this study, we modelled three vocal features—pitch, energy and rate—with linear and quadratic multilevel models to understand how therapists’ vocal features change throughout a therapy session. We hypothesised that all three vocal features would be best fit with a quadratic function—starting high and more congruent with a conversational voice, decreasing during the middle portions of therapy where more therapeutic interventions were being administered, and increasing again at the end of the session. Results indicated a quadratic model for all three vocal features was superior in fitting the data, as compared to a linear model, suggesting that therapists begin and end therapy using a different style of voice than in the middle of a session. 相似文献

A cognitive-behavioral model for conceptualizing wellness is proposed consisting of situational/antecedent variables, person
variables, and consequence variables which, taken individually or together, may serve to describe and explain wellness behavior.
The model also is interactional in the sense that different categories of variables or factors within a category may impact
on each other in a multidirectional fashion. A selective review of research relating to each variable is provided to demonstrate
the need for such a multidimensional conceptual scheme for wellness. 相似文献

Twenty-five managers participated in two parallel 6-hour quasi-experimental simulations. On placebo treatment days, the subjects received hourly placebo drinks. On alcohol treatment days (order counterbalanced), enough alcohol was provided prior to the fourth hour of simulation participation to attain a breath alcohol level (BAL) of near 0.10. All other drinks contained a placebo beverage. Complex task performance was assessed on five variables derived from complexity theory, comparing performance for three measurement periods: (a) prior to the fourth hour of simulation participation (placebo treatment), (b) during the fourth hour (rising BALs on alcohol treatment days), and (c) during the fifth/sixth hours (falling BALs). Alcohol diminished the participants’ breadth of approach (differentiation). Performance on indicators of strategic functioning (integration) decreased after BALs had begun to fall but not while BALs were rising. The implications for performance of complex tasks under the influence of alcohol and for the applicability of the acute tolerance phenomenon to complex task environments are considered. 相似文献

In this pilot study we report on proximate outcomes of a 1-hour community gatekeeper training in-service for 76 nonclinical employees in a university hospital workplace setting. Pre-post analyses resulted in positive changes in participants' knowledge about suicide and attitudes (self-efficacy) about intervening with suicidal individuals. A subset of participants engaged in role play practice of gatekeeper skills following training and rated the experience positively. Fifty-five observations were rated using an observational measure developed for this study and approximately half of these demonstrated satisfactory skills post training. Participants in this workplace gatekeeper training reported sharing new knowledge and skills with family, friends, and coworkers. 相似文献
