Perceptual cues used in reproduction of inspired volume

Man is capable of reproducing an inspired lung volume (IV) with relative precision (±3 %–8 %). To investigate the importance of cues which may be used to determine IV, we performed two experiments. In each, the subject inspired a “standard” breath (from resting end~xpired lung volume) corresponding to 25%, 50%, or 75% of inspiratory capacity (IC) and then expired nearly completely. From this expired volume, the subject either tried to reproduce the tidal volume (i.e., volume of air inspired) of the first breath (volume reproduction) or to reproduce the previous end-inspired lung volume (position reproduction). The constant error indicated that subjects overestimated tidal volume by about 200 ml. Despite this overestimation, the variability of reproduction was less for volume reproduction than for position reproduction when IV was small. The JND for volume reproduction increased linearly with increasing IV, whereas the JND for position reproduction was similar at all IVs so that the Weber ratio decreased. These observations suggest that, in the perception of inspired volume, the sensation of end-inspired position is important when the inspired volume is large, but that subjects apparently rely on some other cue to reproduce small lung volumes accurately.     

How to Improve Athletes' Return of Investment: Shortening Questionnaires in the Applied Sport Psychology Setting

In counseling settings we need short and understandable, as well as valid and reliable, questionnaires. However, test construction focuses primarily on the latter, resulting in rather long tests and athletes' perception of low return on time investment. We address this problem by explaining how questionnaires can be shortened (i.e., using three selection criteria) and validated (e.g., by calculating interitem correlations). As an example we shortened the Thought Occurrence Questionnaire Sport from 17 to three items. We argue why this short version still satisfies quality criteria and why such short(ened) questionnaires should be more appreciated (e.g., by publishing and using them in counseling settings).     

Virtual and physical venues as contexts for HIV risk among rural men who have sex with men.

Rural men who have sex with men (MSM) have few identifiable venues in which to congregate and meet potential sex partners. The Internet provides a venue for rural MSM to meet, and this is potentially troubling because studies of urban MSM suggest that HIV risk is higher for men who date online. The goals of this study were to identify venues where rural MSM meet their sexual partners and to examine their association with high-risk sexual practices. Six hundred sixty-three predominantly single, gay, Caucasian MSM completed an online survey of their sexual activities. Results showed that the Internet and bars were the most popular venues for meeting sex partners. Highest rates of risk behaviors were associated with Internet dating and venues in which immediate sexual encounters typically occur, suggesting that prevention in rural areas should target multiple-risk environments.     

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     

The facilitative interpersonal skills method: Difficult psychotherapy moments and appropriate therapist responsiveness

The Facilitative Interpersonal Skills (FIS) task is a performance test of therapists’ use of common relational skills (e.g. empathy, building expectations). The FIS method includes (a) materials that simulate difficult client moments on video, which are used to collect therapists’ responses to these situations; and (b) independent ratings of these responses. Many of the FIS items are informed by psychotherapy processes that have been linked to outcome and facilitative conditions that have been reframed as individual therapist skills (e.g. alliance bond capacity). Overall, the FIS has predicted psychotherapy outcome. A single study is described in which FIS predicted the therapist effect using multilevel modelling of a large sample of clients who were nested within therapists. We also summarise two additional outcome studies that used experimental designs. One future direction is to better understand how therapists form responses to these difficult moments. We conclude that forming an optimal therapeutic response during challenging, emergent in‐session situations involves responsiveness (Stiles et al., 1998), or finding a response that fits the clients’ needs within any moment.     

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.
