THE MODAL ARGUMENT FOR A PRIORI JUSTIFICATION

Kant famously argued that, from experience, we can only learn how something actually is, but not that it must be so. In this paper, I defend an improved version of Kant's argument for the existence of a priori knowledge, the Modal Argument , against recent objections by Casullo and Kitcher. For the sake of the argument, I concede Casullo's claim that we may know certain counterfactuals in an empirical way and thereby gain epistemic access to some nearby, nomologically possible worlds. But I maintain that our beliefs about metaphysical necessities still cannot be justified empirically. Furthermore, I reject Casullo's deflationary thesis about the significance of such justification. Kitcher's most troublesome objection is that we can gain any modal justification whatsoever through testimony , i.e. in an experiential way. This can be countered by distinguishing between productive sources of justification, like perception, and merely reproductive sources, like testimony. Thus, some productive a priori source will always be needed somewhere. ¹     

A BRIEF FUNCTIONAL ANALYSIS OF AGGRESSIVE AND ALTERNATIVE BEHAVIOR IN AN OUTCLINIC SETTING

We conducted a brief functional analysis to identify maintaining variables for aggressive behavior and an alternative replacement response during a 90-min outpatient evaluation of 3 individuals with severe handicaps. During the initial analogue assessment, which focused on identifying maintaining contingencies for aggressive behavior, each participant displayed a substantially greater frequency of aggressive behavior during one condition than during any other. The contingency that produced the highest percentage of aggressive behavior was then presented for the occurrence of a specific alternative behavior (a mand). During this contingency reversal phase, each participant displayed a substantial reduction in aggressive behavior and a substantial increase in alternative behavior, thus providing a direct analysis of the equivalency of the contingency for maintaining either behavior.     

Lost in the wilderness: terror management, action orientation, and nature evaluation

The authors propose that wilderness is intrinsically associated with death, and, consequently, terror management concerns may promote more negative evaluations of wilderness. Consistent with this, wilderness inspired more thoughts about death than either cultivated nature or urban environments (Study 1), and death reminders reduced perceived beauty of wilderness (Study 2). The authors further suggest that active self-regulation facilitates suppression of the dark side of wilderness. Consistent with this, action orientation was positively related to perceived beauty of wilderness (Study 3), and after viewing wilderness, action-oriented individuals were more efficient at suppressing the association between wilderness and death than state-oriented individuals (Study 4). Direct death reminders overruled the effects of action orientation on nature evaluation (Study 5), presumably because direct death reminders are difficult to suppress even for action-oriented individuals.     

Dispositional Optimism and Marital Adjustment

Research showing the distinct influence of positive attributes on relationships has been growing. This study examined the impact of husbands’ and wives’ dispositional optimism on their own and partner’s relationship satisfaction, consensus, and cohesion using data from the National Survey of Families and Households. Results indicate that wives’ optimism influences their own later marital satisfaction as well as their husbands’ later marital satisfaction. However, husbands’ optimism did not appear to influence their own nor their wives’ later satisfaction. Potential interventions for increasing optimism in the therapeutic setting are discussed.     

On the validity and utility of discriminating among impulsivity-like traits

The ability to make precise distinctions among related personality constructs helps clarify theory and increases the utility of clinical assessment. In three studies, the authors evaluated the validity of distinctions among four impulsivity-like traits: sensation seeking, lack of planning, lack of persistence, and urgency (acting rashly when distressed). Factor analyses indicated that lack of planning and lack of persistence are two distinct facets of one broader trait, whereas urgency and sensation seeking are both very modestly related to each other and to the planning/persistence measures. The authors developed interview assessments of each, and multitrait, multimethod matrix results indicated clear convergent and discriminant validity among the constructs. The distinctions among them were useful: The traits accounted for different aspects of risky behaviors. Sensation seeking appeared to relate to the frequency of engaging in risky behaviors, and urgency appeared to relate to problem levels of involvement in those behaviors.     

The role of fairness perceptions and accountability attributions in predicting reactions to organizational events

Researchers have found that fairness perceptions relate to many different outcomes (e.g., J. A. Colquitt, D. E. Conlon, M. J. Wesson, C. Porter, & K. Y. Ng, 2001). However, they cannot predict when an employee will react against a specific individual or against the organization itself. To address this question, the authors integrated the fairness and blame-attributions literatures. They predicted that blame attributions would strengthen the relationship between fairness perceptions and reactions to specific organizational agents. They surveyed 48 employees who believed there were inaccuracies in their most recent performance appraisals. Employees reported perceptions of fairness and attributions of blame to both their supervisor and the organization and rated their commitment to both targets. Supervisors simultaneously rated each employee's citizenship behavior toward each target. For supervisor reactions and organizational citizenship behavior directed at the organization, blame and fairness perceptions interacted; unique positive reactions were elicited only when the supervisor was perceived as blameless and fair.
