I propose that we approach the epistemology of modality by putting modal metaphysics first and, specifically, by investigating the metaphysics of essence. Following a prominent Neo-Aristotelian view, I hold that metaphysical necessity depends on the nature of things, namely their essences. I further clarify that essences are core properties having distinctive superexplanatory powers. In the case of natural kinds, which is my focus in the paper, superexplanatoriness is due to the fact that the essence of a kind is what causes all the many properties and behaviors that are typically shared by all the instances of the kind. Accordingly, we know what is necessarily true of kinds by knowing what is essential to them in the sense of actually playing such causal-explanatory roles. Modal reasoning aimed at discovering metaphysical necessity thus proceeds via essentialist deduction: we move from essentialist truths to reach necessary truths.
Parents and teachers of children with special needs face unique social-emotional challenges in carrying out their caregiving roles. Stress associated with these roles impacts parents' and special educators' health and well-being, as well as the quality of their parenting and teaching. No rigorous studies have assessed whether mindfulness training (MT) might be an effective strategy to reduce stress and cultivate well-being and positive caregiving in these adults. This randomized controlled study assessed the efficacy of a 5-week MT program for parents and educators of children with special needs. Participants receiving MT showed significant reductions in stress and anxiety and increased mindfulness, self-compassion, and personal growth at program completion and at 2 months follow-up in contrast to waiting-list controls. Relational competence also showed significant positive changes, with medium-to-large effect sizes noted on measures of empathic concern and forgiveness. MT significantly influenced caregiving competence specific to teaching. Mindfulness changes at program completion mediated outcomes at follow-up, suggesting its importance in maintaining emotional balance and facilitating well-being in parents and teachers of children with developmental challenges.

In this study we assess for the first time the driving skills of young adults with developmental coordination disorder (DCD). We use a virtual city and a driving simulator to examine steering control, speed regulation and the responses to pedestrians on the road. Participants were adolescents and young adults who had been diagnosed with the disorder as children. For most participants the symptoms were maintained (DCD group) but for others they had largely dissipated (AD group). We also invited typically developing (control) participants matched in age, gender, and driving experience to the DCD and AD participants. Compared to their matched controls, the DCD group showed difficulties in steering when turning bends but not when driving along straight roads. Although the average speed of the DCD group was similar to their controls this may have been too fast for them to steer effectively around the bends. The DCD group also took 50% more time to react to pedestrians who walked towards their path. We found no such differences between the AD and their matched controls. We discuss the results in terms of visual information processing and suggest further applied and fundamental research on this topic. 相似文献
Butler et al. (Cognitive Therapy and Research 31:357?C370, 2007) developed the Personality Beliefs Questionnaire-Short Form (PBQ-SF), from an earlier longer version (Beck and Beck 1991), to assess the types of schemata associated with different personality disorders. This study explored the structure of PBQ-SF using Guttman??s Smallest Space Analysis. Participants were 228 students who volunteered for the study. The two facets (each with two subsets) suggested by the analysis to characterize the structure of the personality disorder subscales were Ego Concerns (self-enhancement versus self-protection) and Control Concerns (feelings lack of control versus need for control). Clinical implications of the findings include targeting major dysfunctional thinking, as suggested by the aforementioned two facets and their subsets, in the treatment of personality disorders. 相似文献
The focus of the present study lies on optimism and its relationships to the components of subjective well-being, i.e. global
life satisfaction, positive affect and negative affect. We investigated the direct and indirect (via affectivity) effects
of optimism on global life satisfaction in the Swedish middleaged women at two time points (age 43 and 49), and in the Lithuanian
middle-aged women. For this purpose, structural equation modelling was used and the fit indices were compared between two
cognitive-affective models. The best fitting model suggests that the direct effect of optimism on global life satisfaction
is stronger than that via affectivity. The result was found both in the Swedish sample at two time points and in the Lithuanian
sample where the indirect effect was very low and insignificant. The indirect effect via negative affectivity was significant
in the Swedish samples at both time points while the indirect effect via positive affectivity was low but significant only
in the Swedish sample at age 43. In further analyses we studied the stability of optimism and the components of general SWB
in the Swedish sample over a six-year period and a mean difference in optimism in two samples of women, Swedish and Lithuanian.
Data analyses showed varying stability of the studied concepts with the highest stability coefficient being for negative affect
and the lowest being for global life satisfaction. Cross-cultural analysis of mean difference in optimism showed that the
Swedish women at age 43 reported significantly higher optimism as compared to their Lithuanian counterparts. 相似文献
Electrocortical activity, typically used to track the effects of cognitive reappraisal on the processing of emotional stimuli, has not been used to index the prefrontal-cortex-mediated regulatory mechanisms responsible for these effects. In the present study, we examined the novel possibility that induced frontal alpha (i.e., 8?C13?Hz), shown to reflect the inhibition and disengagement of task-relevant cortical regions, may be quantified to explore cortical activation that is specifically enhanced during cognitive reappraisal. For this purpose, 44 participants viewed unpleasant and neutral pictures followed by auditory instructions to either continue viewing the picture or reduce their emotional response to the picture by making the picture seem less emotional (i.e., cognitive reappraisal). In line with previous work, unpleasant pictures elicited a larger late positive potential (LPP) than did neutral pictures. Also corroborating previous work, the mid-latency LPP was reduced when pictures were cognitively reappraised. However, the present study showed for the first time that whereas unpleasant pictures elicited higher frontal alpha power bilaterally than did the neutral pictures, frontal alpha power was reduced (indicative of more activation and cognitive control) during cognitive reappraisal of both picture types over the left hemisphere. Taken together, the LPP and event-related induced frontal-alpha findings contribute unique information about the distinct neural substrates and cognitive processes underlying reappraisal. 相似文献
AbstractModern cognitive science is the outcome of a transdisciplinary effort constituting the largest body of work about the mind in human history. These advancements have guided our understanding of the functional role of the agent’s body and context when producing adaptive behaviour and interactions. Thus, cognition is embodied, embedded, extended and enacted within inward- and outward-directed interactions, which is where the brain/body-in-the-world system emerges. We suggest that the goal of the new cognitive science is to understand the multi-level dynamic mechanisms underlying cognition-in-the-world and review the implications for the relationship between psychology and the social sciences. 相似文献
The purpose of this study is to compare traditional and non-traditional instructional practices used in a counsellor education programme to determine their effect on pre-service school counsellors' learning and sense of community, thus leading to enhanced professional identity. Traditional and non-traditional assignments were examined: (a) a collaborative, multimedia wiki writing assignment; (b) textbook reading and corresponding quizzes; and (c) article critiques. Findings indicate that students experience a greater sense of community and learning when participating in the non-traditional, collaborative, multimedia wiki writing assignment using web-based technology. Findings also indicate that students had low computer anxiety after completing the wiki assignment. 相似文献
The need for professionals to volunteer their time in crisis situations and to reach across time and culture in the service of humanitarian interventions will likely not abate in the near future. This article provides readers with multiple venues for considering the ethical dimensions present in crisis and humanitarian interventions. Core ethical concerns common to helping situations are magnified in crisis work. In addition, issues unique to the nature of volunteer and crisis work must also be considered. Using hypothetical case examples, bioethical principles, and ethical decision-making models, helping professionals are encouraged to go beyond their particular ethical codes in contemplating ethically and clinically sensitive volunteering. 相似文献
