How to Throw a Pot: The Centrality of the Potter's Wheel in the Zhuangzi

This article explains Zhuangzi's philosophy by analyzing the metaphor of the potter's wheel. I argue that this is one of the central images in the core chapters of the Zhuangzi. Together with two cognate images, it not only appears in some crucial passages, but also allows us to integrate a variety of seemingly independent topics. The article consists of four sections. I start by placing the potter's wheel against a background of other artisan tools. A second section focuses on three major themes revolving around the image of the potter's wheel in the Zhuangzi: stillness of mind, flexibility in response, and harmonizing and living out one's years. A third section discusses the negative portrayal of measurement tools in the Zhuangzi. In an afterword, I summarize the findings and revisit some methodological issues. The study shows that concrete images such as artisan tools may provide important clues for interpreting philosophical texts.     

A randomized clinical trial on the effectiveness of a reintegration training program versus booster sessions after short-term inpatient psychotherapy

Although several studies show symptomatic improvements in patients with personality disorders after short-term inpatient psychotherapy, reintegration remains difficult. In this study the effectiveness of a specifically designed reintegration training program is investigated. One hundred twenty-eight patients were randomized to either a reintegration training program aimed at improving general functioning and work resumption, or booster sessions. Outcome measures used were symptom level, work status, absence from and impediments at work. The results showed that compliance in the booster session group was significantly better than in the reintegration training program. The percentage of persons with a paid job increased during the booster sessions from 64 to 87%, but not during the reintegration training (76%). There were no differences in the other outcome measures. We concluded that reintegration training was not more (cost)-effective than booster sessions. Our hypothesis is that continuity of care (same therapists and program) explains the favorable results of the booster sessions.     

No protective effects of education during normal cognitive aging: results from the 6-year follow-up of the Maastricht Aging Study

Recent large-scale longitudinal aging studies question earlier claims that higher education protects against cognitive decline in older age. In the present study, the authors addressed this issue by determining whether educational level had an attenuating effect on the rate of cognitive change assessed with a broad range of neuropsychological tests in a community sample of 872 healthy individuals aged 49 to 81 years at baseline. The participants were followed for 6 years and were tested 3 times (at baseline and at 3 and 6 years after baseline). Results of linear mixed-model analyses showed that education had no significant effect on cognitive change over time. These results are discussed in terms of the age range of the sample, definition and range of education, cognitive measures used, length of the study and number of consecutive assessments, and confounding effect of health. The findings question the extent of the presumed protective effects of higher education on cognitive decline during normal aging.     

Smarter than we think: when our brains detect that we are biased

Human reasoning is often biased by stereotypical intuitions. The nature of such bias is not clear. Some authors claim that people are mere heuristic thinkers and are not aware that cued stereotypes might be inappropriate. Other authors claim that people always detect the conflict between their stereotypical thinking and normative reasoning, but simply fail to inhibit stereotypical thinking. Hence, it is unclear whether heuristic bias should be attributed to a lack of conflict detection or a failure of inhibition. We introduce a neuroscientific approach that bears on this issue. Participants answered a classic decision-making problem (the "lawyer-engineer" problem) while the activation of brain regions believed to be involved in conflict detection (anterior cingulate) and response inhibition (lateral prefrontal cortex) was monitored. Results showed that although the inhibition area was specifically activated when stereotypical responses were avoided, the conflict-detection area was activated even when people reasoned stereotypically. The findings suggest that people detect their bias when they give intuitive responses.     

Post-error slowing: An orienting account

It is generally assumed that slowing after errors is a cognitive control effect reflecting more careful response strategies after errors. However, clinical data are not compatible with this explanation. We therefore consider two alternative explanations, one referring to the possibility of a persisting underlying problem and one on the basis of the low frequency of errors (orienting account). This latter hypothesis argues that infrequent events orient attention away from the task. Support for the orienting account was obtained in two experiments. Using a new experimental procedure, Experiment 1 demonstrated post-error slowing after infrequent errors and post-correct slowing after infrequent correct trials. In Experiment 2, slowing was observed following infrequent irrelevant tones replacing the feedback signals.     

The size of the Simon effect depends on the nature of the relevant task

Four experiments were conducted to investigate contextual modulations of the Simon effect. The results showed that the Simon effect was quantitatively different depending on which kind of task needed to be performed. Importantly, this effect did not depend on the relative processing time of the relevant dimension, nor on a direct or indirect overlap between the relevant and irrelevant stimulus part. To account for the data, we refer to the neural overlap hypothesis, which extends the definition of dimensional overlap (Kornblum, Hasbroucq, & Osman, 1990) with similarity of processing regions as the key factor for the interaction between relevant and irrelevant information processing.     

Empathy and conflict resolution in friendship relations among adolescents

The present study addressed empathy's role in conflict resolution within the context of adolescent same-sex friendship relations. Self-report questionnaires were used to assess dispositional affective empathy and conflict resolution styles (problem solving, conflict engagement, withdrawal and compliance). The data of 307 adolescents (149 boys, 158 girls) were included in a multigroup path analysis with sex as a moderator variable. In agreement with the hypothesis that higher levels of dispositional empathy are associated with more successful conflict management, dispositional affective empathy was found to be positively linked to problem solving and negatively linked to conflict engagement among adolescent boys and girls. Dispositional affective empathy was not related to the two more passive strategies (withdrawal and compliance). Sex differences were demonstrated in empathic tendencies, with girls being more empathic than boys. Sex differences were also established in conflict resolution strategies, with girls using problem solving, withdrawal and compliance more frequently than boys. Both sexes scored equally low on conflict engagement, however, and were found to prefer problem solving to all other conflict resolution strategies. Findings are discussed in terms of previous research on empathy and conflict resolution.     

The issue of generality in ethics

Conclusion Does ethics have adequate general theories? Our analysis shows that this question does not have a straightforward answer since the key terms are ambiguous. So we should not concentrate on the answer but on the question itself. Ethics stands for many things, but we let that pass. Adequate may refer to varied arrays of methodological principles which are seldom fully articulated in ethics. General is a notion with at least three meanings. Different kinds of generality may be at cross-purposes, so we must not expect theories to be general in sundry senses. Theory, for that matter, is itself ambiguous. Some thinkers say that ethics cannot have theories, while others deny it. We doubt whether opposing parties are talking about the same things.No wonder, then, that controversies in ethics are long-lasting and unproductive. We hope that the methodology we have presented will alleviate some of them. The examples we chose show that this is feasible. Views such as Hare's and Jonsen and Toulmin's which are seemingly wide apart, show convergence if we put them in a methodological perspective.Our analysis also suggests that many alleged differences between science and ethics could fade away if methodology is brought to bear on them. Specifically, the idea that ethics compares poorly with science in view of limited generality, or poor means of justification, is unfounded. Those who defend this view over-rate the powers of science.
