A Cognitive (Attributions)-Emotion Model of Observer Reactions to Free-Riding Poor Performers

Whereas most free-riding research has focused on limiting free-riding and on understanding free-riding motives, we were concerned with capturing the psychological processes used by observers to interpret the poor performance behavior of a team member. Using a sample of 268 observers of a simulated team interaction, we found that peer reactions to a poor performance could be explained through attribution theory (AT). Poor performers perceived as possessing high general cognitive ability (g) and low conscientiousness traits were more likely to be rated high on free-riding when compared to those perceived as possessing low g/low conscientiousness traits. In addition, AT helped explain observer anger and intent to punish free-riders.

Are There Stable Factors in Preadolescent Girls’ Externalizing Behaviors?

Relatively little is known about the factor structure of disruptive behavior among preadolescent girls. The present study reports on exploratory and confirmatory factor analyses of disruptive girl behavior over four successive data waves as rated by parents and teachers in a large, representative community sample of girls (N = 2,451). Five factors were identified from parent ratings (oppositional behavior/conduct problems, inattention, hyperactivity/impulsivity, relational aggression, and callous-unemotional behaviors), and four factors were identified derived from teacher ratings (oppositional behavior/conduct problems/callous-unemotional behaviors, inattention, hyperactivityimpulsivity, and relational aggression). There was a high degree of consistency of items loading on equivalent factors across parent and teacher ratings. Year-to-year stability of factors between ages five and 12 was high for parent ratings (ICC = 0.70 to 0.88), and slightly lower for teacher ratings (ICC = 0.56 to 0.83). These findings are discussed in terms of possible adjustment to the criteria for children's disruptive behavior disorders found in the Diagnostic and Statistical Manual for Mental Disorders.

It’s not just what you know, it’s who you know: Testing a model of the relative importance of social networks to academic performance

Applying three mathematical modeling techniques, this study proposes and tests the fit of an academic performance model, and then estimates the relative importance of four performance predictors: academic ability, performance goal orientation, educational technology use, and social network density. Drawing on social network theory, findings from this study show that social network density is a statistically important and unique predictor of academic performance, suggesting that “who you know” matters in large classroom settings. However, this study also indicates that academic ability is the most dominant factor in the explanation of academic performance. Practical and theoretical implications for enhancing academic performance through social networks are discussed.

Naturalistic Explanations of Apodictic Moral Claims: Brentano’s Ethical Intuitionism and Nietzsche’s Naturalism

In this article (1) I extract from Brentano’s works (three) formal arguments against “genealogical explanations” of ethical claims. Such explanation can also be designated as “naturalism” (not his appellation); (2) I counter these arguments, by showing how genealogical explanations of even apodictic moral claims are logically possible (albeit only if certain unlikely, stringent conditions are met); (3) I show how Nietzsche’s ethics meets these stringent conditions, but evolutionary ethics does not. My more general thesis is that naturalism and intuitionism in ethics need not be mutually incompatible.

Towards a New Epistemology of Mathematics

In this introduction we discuss the motivation behind the workshop “Towards a New Epistemology of Mathematics” of which this special issue constitutes the proceedings. We elaborate on historical and empirical aspects of the desired new epistemology, connect it to the public image of mathematics, and give a summary and an introduction to the contributions to this issue.

Clinical Efficacy of Ritual Healing and Pastoral Ministry

This article seeks to explain the relationship between religion and healing with special reference to the phenomenon of ritual healing. Relying on diverse research findings that articulate the relationship between ritual and healing, this article contends that the clinical efficacy of ritual is sustainable by invoking the concepts of self-healing and placebo effect, and that its efficacy lies in its performance, not in its meaning being either decodable by the ritual performers or theologically encodable by professional thinkers. This, I contend, has practical implications for pastoral care and counseling ministry.

Sosa on scepticism

 In my remarks, I discuss Sosa's attempt to deal with the sceptical threat posed by dreaming. Sosa explores two replies to the problem of dreaming scepticism. First, he argues that, on the imagination model of dreaming, dreaming does not threaten the safety of our beliefs. Second, he argues that knowledge does not require safety, but a weaker condition which is not threatened by dreaming skepticism. I raise questions about both elements of his reply.

Terrorism,Post-traumatic Stress,Coping Strategies,and Spiritual Outcomes

This mail survey measured post-traumatic stress symptoms, spiritual and non-spiritual coping strategies, and positive spiritual outcomes following the tragedies of 9/11/01 in a national, random sample of 1,056 Presbyterians. Respondents reported mild to moderate degrees of re-experiencing and hyper-arousal symptoms of post-traumatic stress, unrelated to location or knowing someone involved. People experiencing high stress used greater frequency and variety of both spiritual and non-spiritual types of coping strategies. Positive spiritual outcomes were remarkably related to positive spiritual coping strategies, in contrast to no association with negative coping. This study illustrates the significant degree of post-traumatic stress experienced with vicarious exposure and a wide spectrum of coping strategies used following the major terrorist attacks.

Factors Influencing Employee Intentions to Provide Honest Upward Feedback Ratings

Based on current research involving rater motivation, we examined several factors hypothesized to influence employee intentions to provide honest upward feedback. Survey data were collected from a demographically diverse sample of hospital employees (n = 203). In summary, we found empirical support for generalizing extant models of rater motivation to an upward feedback context: cynicism towards upper management and the upward feedback process, understanding upward feedback, and opportunity to observe their supervisors were the primary predictors of employee intentions to provide honest upward feedback ratings, mediated by the (a) extent to which employees perceived positive benefits would result from rating their supervisors honestly, (b) the extent to which employees feared retaliation by their supervisors, and (c) rater self-efficacy.

Remarks on Grandi’s Comments

This note is a reply to some of Giovanni Grandi’s comments on my paper “Berkeley’s Contingent Necessities.”

Reliabilism in philosophy

The following three propositions appear to be individually defensible but jointly inconsistent: (1) reliability is a necessary condition on epistemic justification; (2) on contested matters in philosophy, my beliefs are not reliably formed; (3) some of these beliefs are epistemically justified. I explore the nature and scope of the problem, examine and reject some candidate solutions, compare the issue with ones arising in discussions about disagreement, and offer a brief assessment of our predicament.

Lack of autonomy and self-control: Performance contingent rewards lead to greater depletion

Exerting self-control appears to deplete a needed resource, which leads to poorer self-control subsequently. However, the amount of depletion may vary, based on how controlling versus autonomy supportive the situation is. In particular, feeling compelled to exert self-control may deplete more strength than having more freedom when exerting self-control. In three experiments, participants who were given performance contingent rewards to exert self-control performed more poorly on a subsequent test of self-control than participants who were non-contingent rewards. There were no differences in mood, arousal, or anxiety between the groups; however, feelings of autonomy were related to self-control performance. The results have implications for understanding self-control depletion, as well as the impact of autonomous motivation on self-control performance.

Visualizations in Mathematics

In this paper we discuss visualizations in mathematics from a historical and didactical perspective. We consider historical debates from the 17th and 19th centuries regarding the role of intuition and visualizations in mathematics. We also consider the problem of what a visualization in mathematical learning can achieve. In an empirical study we investigate what mathematical conclusions university students made on the basis of a visualization. We emphasize that a visualization in mathematics should always be considered in its proper context.

Early Modern Intentionalism: Replies to LoLordo’s Comments

I clarify Locke’s intentionalism and explain what we might gain by paying more attention to the role of linguistic intentions in the work of the British empiricists.

Anxiety and defensiveness: individual differences in affective startle modulation

Anxious individuals selectively attend to threatening information, and defensiveness may influence the experience and expression of anxiety. Fifty-eight undergraduates scoring high and low on measures of anxiety and defensiveness viewed pleasant, neutral, and unpleasant pictures. Acoustic startle probes were presented 60, 240, or 2,000 ms after picture onset. At 60 ms and 240 ms, repressors (low anxiety, high defensiveness) showed weaker blinks during both pleasant and unpleasant compared to neutral pictures, suggesting enhanced early attention to affective stimuli, regardless of valence. At 2,000 ms, high-anxious but not low anxious participants showed potentiated startle responses during unpleasant compared to pleasant pictures. Although this result replicated previous research on anxiety and valence modulation of startle, exploratory analyses suggested that the valence effect was restricted to trait anxious individuals tending toward a defensive coping style. Across probe conditions, defensiveness was associated with heightened startle reactivity independent of self-reported anxiety and foreground stimulus characteristics.

Phenomenology and the Third Generation of Cognitive Science: Towards a Cognitive Phenomenology of the Body

Phenomenology of the body and the third generation of cognitive science, both of which attribute a central role in human cognition to the body rather than to the Cartesian notion of representation, face the criticism that higher-level cognition cannot be fully grasped by those studies. The problem here is how explicit representations, consciousness, and thoughts issue from perception and the body, and how they cooperate in human cognition. In order to address this problem, we propose a research program, a cognitive phenomenology of the body, which is basically motivated by the perspective of Merleau-Ponty. We find a substantial clue in developmental psychological studies on the body and language.

Strategic Maneuvering in Mathematical Proofs

This paper explores applications of concepts from argumentation theory to mathematical proofs. Note is taken of the various contexts in which proofs occur and of the various objectives they may serve. Examples of strategic maneuvering are discussed when surveying, in proofs, the four stages of argumentation distinguished by pragma-dialectics. Derailments of strategies (fallacies) are seen to encompass more than logical fallacies and to occur both in alleged proofs that are completely out of bounds and in alleged proofs that are at least mathematical arguments. These considerations lead to a dialectical and rhetorical view of proofs.
