Empirical evidence and the knowledge-that/knowledge-how distinction

In this article I have two primary goals. First, I present two recent views on the distinction between knowledge-that and knowledge-how (Stanley and Williamson, The Journal of Philosophy 98(8):411–444, 2001; Hetherington, Epistemology futures, 2006). I contend that neither of these provides conclusive arguments against the distinction. Second, I discuss studies from neuroscience and experimental psychology that relate to this distinction. Having examined these studies, I then defend a third view that explains certain relevant data from these studies by positing the double dissociation of knowledge-that and knowledge-how and that is also able to do explanatory work elsewhere.     

Unfinished business: How completeness affects the impact of emotional states and emotion concepts on social judgment

In two studies, we compared the impact of cold emotion concept primes with induced hot emotional states on subsequent social judgments. We hypothesized that the completeness of the prime episode is an important determinant of whether accessible information will lead to emotionally congruent or incongruent judgments. We extend previous research on knowledge and emotion accessibility effects by demonstrating that the effects of incomplete versus completed prime episodes are independent of whether we prime emotion states or emotion concepts. That is, our results show that both hot and cold affective information activated by incomplete prime episodes leads to assimilation, whereas information activated by completed prime episodes leads to contrast effects. Implications for accessibility research are discussed.     

Own-other differences in the realism of some metacognitive judgments

The present study investigated differences in judgments of one's own and others' knowledge (the own-other difference). Consistent with the below-average effect (e.g., Kruger, 1999), our main results showed that the participants gave lower knowledge ratings of their own extent of knowledge than of another person's extent of knowledge (Experiment 1). Furthermore, lower and more realistic judgments were found when the participants judged their own as compared with when judging another person's overall accuracy (frequency judgments) of answering knowledge questions correctly (Experiment 1 and 2). On the basis of these results it is argued that judgmental anchoring may be important also in the context of indirect comparisons, and that previous conclusions of cross-cultural psychology regarding the above-average effect may be oversimplified.     

The physical self-attribute questionnaire: development and initial validation

The Physical Self-attribute Questionnaire was developed for use in conjunction with the Physical Self-perception Profile to model cognitive facets of perceived competence, certainty, importance, and discrepancy from ideal to each of the physical subdomains measured by the latter (Strength, Attractive Body, Condition, and Sport). To this end, two studies were conducted. Study 1 examined the factor structure, test-retest reliability, and validity of the questionnaire in a sample of 154 (28 men, 126 women) undergraduate health students. Reliability and validity were acceptable, and confirmatory factor analysis indicated good fit for a four-factor solution. In Study 2, the reliability, validity, and factor structure was again confirmed in a sample of 120 (83 men, 37 women) undergraduate students recruited from exercise classes. Results of these two studies suggest that the Physical Self-attribute Questionnaire is a viable tool to measure the underlying cognitive facets of subdomain-specific physical self-esteem.     

The time of perception and the other way around

The world we perceive is delayed in relation to its flowing content, as well as the outcome of our actions on the world in relation to the moment we decide to act. This mosaic of different latencies permeating both perception and action has to be taken into account critically in order for us to cope with the temporal challenges constantly imposed by the environment. Fundamental notions, such as the sense of agency and causality, depend on the temporal relationship of events occurring in well-defined windows of time. Here, we offer a broad, yet abridged, historical view of some thought-provoking issues concerning the time of perception and action. From the pioneering work of Wundt, Titchener, and Libet to recent findings and ideas related to the employment of visual illusions as psychophysical probes (such as the flash-lag effect), we have tried to expose some problems inherent to the act of measuring the time of both perception and action, and devise possible solutions as well.     

Negative affect and interpersonal rejection among prison inmates in a therapeutic community: a social relations analysis.

The authors used D. A. Kenny's social relations model to examine J. C. Coyne's interpersonal theory of depression among a clinical sample of well-acquainted prison inmates. Members of 12 therapy groups (N = 142) diagnosed with a substance abuse disorder completed a self-report measure of depression and anxiety and indicated their desire to interact with other group members. There was both consensus about which group members were rejected and individual differences in the participants reported desire for future interaction with other group members. Those reporting high levels of depressive negative affect were most likely to be rejected. Those lowest in positive affect indicated the least desire for future interaction with others.     

Effects of parent training on parent and child behavior using procedures based on functional analyses

We evaluated the effects of parent training for four children whose aberrant behaviors were maintained by social positive or negative reinforcement. Interventions were based on the behavioral function of the problem behavior. Child participants were four children (ages 3 to 5 years) who had developmental delays and exhibited significant aberrant behaviors (tantrums and aggression). The children's mothers were the parent participants. The children's behavior improved as a function of the parents' performance. Copyright © 2001 John Wiley & Sons, Ltd.     

Self‐disclosure,trauma and the pressures on the analyst

This paper argues that self‐disclosure is intimately related to traumatic experience and the pressures on the analyst not to re‐traumatize the patient or repeat traumatic dynamics. The paper gives a number of examples of such pressures and outlines the difficulties the analyst may experience in adopting an analytic attitude – attempting to stay as closely as possible with what the patient brings. It suggests that self‐disclosure may be used to try to disconfirm the patient's negative sense of themselves or the analyst, or to try to induce a positive sense of self or of the analyst which, whilst well‐meaning, may be missing the point and may be prolonging the patient's distress. Examples are given of staying with the co‐construction of the traumatic early relational dynamics and thus working through the traumatic complex; this attitude is compared and contrasted with some relational psychoanalytic attitudes.     

Does the Convergent Validity of the PAI Antisocial Features Scale Depend on Offender Response Style?

Researchers have recently questioned the utility of the response style indicators included on many self-report measures of personality and psychopathology. We examined whether the size of convergent validity coefficients for Personality Assessment Inventory (PAI) Antisocial Features (ANT) scores depends on PAI validity scale scores. Using PAI and Psychopathy Checklist–Revised (PCL–R) scores from 477 offenders evaluated for civil commitment as sexually violent predators, we found that PAI Positive Impression (PIM), Negative Impression (NIM), Malingering Index (MAL), Defensiveness Index (DEF), and Infrequency (INF) scores moderated the association between ANT and PCL–R scores. The association between ANT and PCL–R scores decreased as offenders overstated psychopathology (i.e., higher NIM or MAL scores) or exhibited increasing disengagement (i.e., higher INF scores). However, the association between ANT and PCL–R scores increased as offenders engaged in defensive reporting (i.e., higher PIM or DEF scores). The interaction effects were most common for ANT–E (Egocentricity), and to a lesser extent ANT–A (Antisocial Behaviors). PAI discriminant function validity indexes did not exhibit moderating effects on ANT and PCL–R scores. There was no evidence of validity scale suppression effects. These findings provide support for the potential role of some PAI response style measures for ANT scale interpretation in forensic settings.
