Fine's Fragmentalist Interpretation of Special Relativity

In “Tense and Reality”, Kit Fine ( 2005 ) proposed a novel way to think about realism about tense in the metaphysics of time. In particular, he explored two non‐standard forms of realism about tense (“external relativism” and “fragmentalism”), arguing that they are to be preferred over standard forms of realism. In the process of defending his own preferred view, fragmentalism, he proposed a fragmentalist interpretation of the special theory of relativity (STR), which will be our focus in this paper. After presenting Fine's position, we will raise a problem for his fragmentalist interpretation of STR. We will argue that Fine's view is in tension with the proper explanation of why various facts (such as the Lorentz transformations) obtain. We will then consider whether similar considerations also speak against fragmentalism in domains other than STR, notably fragmentalism about tense.     

Beyond the information given: The power of a belief in self‐interest

How do we interpret other's behavior when we lack important pieces of information? Do we give the other the benefit of the doubt, believing that the other behaves in a fair manner? Or do we “fill in the blanks” with self‐interest? To address these questions, we designed a new method—the dice‐rolling paradigm—in which participants observed another person assigning outcomes by rolling two dice and allocating one of them to the participant, who only had information about one of the two dice. Using different baselines, the results revealed that participants underestimated the outcomes the other allocated to the participants, and overestimated the outcomes the other allocated to self, indicating that people assume self‐interest from others when information is incomplete.

The family as its own reflecting team: a family therapy method

Social research has suggested that people, in general, tend to overestimate their skills and abilities. Interestingly, research has found that peers are better predictors of a person's behaviour than self‐assessment, suggesting that others know us better than we know ourselves. Family therapists should be aware that family members might not give accurate accounts of themselves. In order to overcome this problem, therapists should incorporate peer assessments into therapy. Reflecting teams and videotaping do incorporate peer assessments, yet these methods can be impractical. This article describes a method of family therapy using enactments as a means of setting up the family as its own reflecting team. The method suggests that the family and therapist switch roles several times during the enactment, and then encourages a discussion on the peer observations on how each person addresses a problem in the family. Case examples illustrate how feedback from peers promotes insights.     

Applying test operating characteristics to measures of exercise motivation: A primer

Physical activity programmes that include a motivational counselling component can be effective at increasing exercise participation. Reliable screening procedures could provide a cost effective method of identifying and channelling those ‘at risk’ for non‐participation into a motivational counselling intervention and increase participation and long‐term adherence. Traditional statistical methods have played an important step in developing measures that are good predictors of future exercise behaviour. Test operating characteristics (TOCs), a set of clinical outcome statistics, could be used to evaluate the accuracy of these measures as screening tools in identifying those ‘at risk’ for non‐participation and those ‘not at risk’ for use in applied settings, such as physical activity programmes. This paper will provide a primer on the use of TOCs, particularly as they apply to the evaluation of measures of exercise motivation. Also provided is an example application using eight measures of exercise motivation previously used in research.     

Do brands of a feather flock together? Some exploratory findings on the role of individual brands in brand constellation choice

In this paper, consumers' choice of brand constellations (eg Big Mac and Coke at McDonald's) are investigated by examining the roles of individual brands. The author proposes that marketers need to look beyond perceived fit between brands within a brand constellation. Therefore, this paper explores empirically how individual brand evaluations at product level and at brand level affect brand constellation choice. It is shown that brands do not have to be equally attractive in order to be included in brand constellations. For instance, a weak brand may complement a strong brand. Theoretical and marketing implications are discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

The Psychological Benefits of Superstitious Rituals in Top Sport: A Study Among Top Sportspersons1

The current research addresses the psychological benefits of superstitious rituals in top sport, examining the circumstances under which top‐class sportspersons are especially committed to enacting rituals prior to a game (ritual commitment). Consistent with the hypotheses, findings revealed that ritual commitment is greater when (a) uncertainty is high rather than low; and (b) importance of the game is high rather than low. Complementary analyses revealed that the state of psychological tension mediated both effect of importance and uncertainty on ritual commitment. Moreover, players with an external locus of control exhibited greater levels of ritual commitment than did players with an internal locus of control. The results are discussed in terms of the tension‐regulation function of superstitious rituals in top sport.     

An examination of the psychometric properties of scores on the Family Strain Index (FSI) in a general community sample

Given the potentially harmful effects of parenting stress on parents, children, and their relationship, it is critical to have a reliable and valid measure of parenting stress in clinical and community samples. The Family Strain Index (FSI) is a brief questionnaire designed to measure stress and demand on parents of children with ADHD. The present study is the first to evaluate the psychometric properties of scores on the FSI in a general community sample. Parents (89% mothers) of 550 preschool children (aged 2–5 years; 50% boys) sampled through 17 kindergartens located in Danish cities and villages completed the FSI, the ADHD Rating Scale (RS)‐IV Preschool Version, and a background questionnaire. FSI scores were characterized by restricted range and floor effects. The scale's construct validity was not supported and the measurement repeatability after 1 month was low. The scale did have convergent validity as levels of parenting stress were associated with perceived ADHD behavior in off‐spring, but overall, results did not encourage the use of the FSI as a measure of parenting stress in the general population. Measures that include more normative events may be more appropriate when attempting to capture parenting stress in general community samples.     

Identification and location tasks rely on different mental processes: a diffusion model account of validity effects in spatial cueing paradigms with emotional stimuli

Spatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants’ primary task is. In one variant, participants indicate the location of the target (location task), whereas in the other they indicate the shape of the target (identification task). In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies (total N?=?397; two in the supplement) using both variants and manipulating the motivational relevance of cue content, diffusion model analyses revealed that cue validity effects in location tasks are primarily driven by response biases, whereas the same effect rests on delay due to attention to the cue in identification tasks. Based on this, we predict and empirically support that a symmetrical distribution of valid and invalid cues would reduce cue validity effects in location tasks to a greater extent than in identification tasks. Across all variants of the task, we fail to replicate the effect of greater cue validity effects for arousing (vs. neutral) stimuli. We discuss the implications of these findings for best practice in spatial cueing research.     

The relationship between high performance and knowledge about how to master cooperation situations

This paper applies the expertise approach to cooperation settings and examines high performers' knowledge about cooperation situations. We argue that high performers know more about how to address cooperation situations than do moderate performers. Specifically, we assume that they know more about problem analysis, about how to address the task, the cooperation partner and the cooperation partners' task approach. We report findings of two empirical studies in which study participants responded to scenario situations. The first study based on a sample of 39 software professionals showed that high performers were superior with respect to overall knowledge and specific knowledge aspects. The second study based on a sample of 62 engineers partially replicated these findings. High performers' better knowledge of cooperation situations could not be explained by years of experience or perspective taking. However, situation‐specific experiences partially accounted for the relationship between performance level and knowledge. Copyright © 2002 John Wiley & Sons, Ltd.
