Development of a device to measure human sound localization

Measurements of human sound discrimination and localization are important for basic empirical and clinical applications. After a short survey of other methods such as evoked potentials, the development of a new device to measure human sound localization is described and its use illustrated with some examples. Built from a polyacrylic hemisphere or--in a later version--from an orbicular aluminum frame, the apparatus uses multiple speakers to emit auditory stimuli. The patient sits in the middle of the perimeter and has to press a button when a sound is perceived. In addition, the participant has to identify the correct speaker as the source of the sound. With this method it is possible to map the auditory field.     

Asymmetrical scepticism towards criminal evidence: The role of goal‐ and belief‐consistency

Previous demonstrations of asymmetrical scepticism (i.e., that investigators perceive evidence inconsistent [vs. consistent] with the focal hypothesis of a case as less reliable) have failed to account for the underlying mechanism. This study examined whether inconsistent evidence is discredited due to its inconsistency with a prior belief or because it conflicts with the goal to reach closure in a case. Police trainees (N = 107) were presented with a homicide case and judged the reliability of incriminating or exonerating evidence while entertaining a ‘guilty’ or ‘innocent’ hypothesis concerning a suspect. Asymmetrical scepticism was observed in the guilty condition, but not in the innocent condition, partially supporting the goal‐consistency explanation. Implications for the organization of criminal investigations are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

The delay of gratification test for adults: Validating a behavioral measure of self-motivation in a sample of older people

Most previous delay of gratification tests were developed for children and are inappropriate for application in adults. The authors therefore developed the Delay of Gratification Test for Adults (DoG-A), which includes four types of reward that are meaningful to adults, namely snacks, real money, hypothetical money, and magazines. Four subscores and two composite scores can be calculated. This study is the first to evaluate the DoG-A and to investigate its association with external variables. A community sample of 147 cognitively healthy participants aged between 60 and 94 years completed a questionnaire and cognitive tests measuring delay discounting, self-regulation, motivational self-concept, personality, wellbeing, and cognitive function. The intercorrelations of the subscales were low to medium and the internal consistency of the composite scores was moderate (?? = .4), indicating relative domain independence of the four reward types. The nomological net established by investigating the relations of the DoG-A with other constructs proved to be fairly meaningful. The correlations of all subscales with the delay discounting rate were significant and moderate. The Snacks subscale showed the most consistent pattern of results in terms of moderate positive correlations with self-reported motivation regulation, optimism, dutifulness, and deliberation. The Snacks subscale also correlated with various measures of wellbeing. A regression analysis showed that DoG Snacks remained a significant predictor of wellbeing when self-reported self-regulation and other variables were controlled. These findings indicate that the DoG-A yields an interpretable behavioral measure of self-motivation and offers a developmentally adequate extension of the delay of gratification paradigm for use with adults.     

A Proof-theoretic View of Necessity

We give a reading of binary necessity statements of the form “ϕ is necessary for ψ” in terms of proofs. This reading is based on the idea of interpreting such statements as “Every proof of ψ uses ϕ”.     

Explicit Persuasive Intent and Its Impact on Success at Persuasion—The Determining Roles of Attractiveness and Likeableness

The effect on the impact of a message of explicitly stating a desire to persuade can depend on the communicator's physical attractiveness. Experiment 1 confirmed this possibility. Attractive male and female salespersons induced more positive attitudes and stronger intentions to purchase a product when they explicitly stated their desire to influence potential buyers. In contrast, unattractive salespersons were less likely to induce a favorable attitude toward the product under these conditions. Experiment 2 replicated these effects and provided evidence that they are mediated by the attribution of self‐serving motives to the salesperson. A 2‐step process of impression formation and attribution was used to describe the mechanisms underlying these effects.     

Regaining a sense of agency and shared self-reliance: the experience of advanced disease cancer patients participating in a multidimensional exercise intervention while undergoing chemotherapy--analysis of patient diaries

Evidence is emerging that exercise can reduce psychological distress in cancer patients undergoing treatment. The present study aimed to (qualitatively) explore the experiences of advanced disease cancer patients participating in a 6-week, 9-hours weekly, structured, group-based multidimensional exercise intervention while undergoing chemotherapy. Unstructured diaries from a purposive sample of three females and two males (28-52 years old) who participated in the program served as the database. Data were analyzed using a phenomenological, narrative method. The analysis yielded three themes: shifting position, self-surveillance, and negotiated strength. The intervention highlighted situations making it possible for the participants to negate psychological and physical constraints. The concept of structured exercise contains viable psychotherapeutic potentials by allowing the development of alternative bodily and mental realities complying with cancer patients' demands and abilities to regain autonomy and commitment to discover and adopt a sense of agency and shared self-reliance.

Die Vorhersage der Rückfälligkeit entlassener Sexualstraftäter mittels des Sexual Offender Risk Appraisal Guide (SORAG) und dessen Screening-Version (SORAG-SV): Darstellung der differentiellen und prädiktiven Validität

The Sex Offender Risk Appraisal Guide (SORAG) is one of the most important actuarial risk assessment instruments for sexual offenders. In the meantime, the application of actuarial instruments in recidivism risk assessment for sexual offenders is regarded as state of the art. In addition to results about interrater reliability and concurrent validity we present results about the differential and predictive validity of the SORAG and a screening version of the SORAG (SORAG-SV), which relies only on file information. In order to examine the predictive validity, we used a representative sample of 519 male sexual offenders released from a prison sentence served in one of Austrian´s prisons with a mean follow-up period of 3½ years. Furthermore, we tested the differential validity by dividing the whole sample in different subsamples regarding age, index offense type, and degree of antisociality. Both SORAG and SORAG-SV showed predominantly good predictive accuracy which, however, varied depending on offender subgroup and recidivism category.
