INCREASING THE VARIETY OF FOODS CONSUMED BY A PICKY EATER: GENERALIZATION OF EFFECTS ACROSS CAREGIVERS AND SETTINGS

A multiple baseline across settings was used to evaluate the effects of differential reinforcement of alternative behavior, nonremoval of the fork ( Hoch, Babbitt, Coe, Krell, & Hackbert, 1994 ), and stimulus fading on consumption of food rejected previously. The study was conducted in two separate settings, and caregivers were trained in the intervention technique to increase generalization to natural settings. Food variety increased in both settings.     

Non-standard Stochastics with a First Order Algebraization

Internal sets and the Boolean algebras of the collection of the internal sets are of central importance in non-standard analysis. Boolean algebras are the algebraization of propositional logic while the logic applied in non-standard analysis (in non-standard stochastics) is the first order or the higher order logic (type theory). We present here a first order logic algebraization for the collection of internal sets rather than the Boolean one. Further, we define an unusual probability on this algebraization.     

Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial

Halvorsen, J.Ø. & Stenmark, H. (2010). Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial. Scandinavian Journal of Psychology 51, 495–502. Torture has severe mental health effects, especially in terms of posttraumatic stress disorder (PTSD) and depression. However, there is still a lack of empirical treatment studies. The present paper presents data on 16 torture survivors receiving 10 sessions of narrative exposure therapy (NET). Symptoms of PTSD and depression, assessed by Clinician‐Administered PTSD Scale (CAPS) and Hamilton Rating Scale for Depression (HRSD), decreased significantly from pre‐treatment to 6‐month follow‐up, with Cohen’s d effect sizes of 1.16 and 0.84, respectively. Although treatment gains were moderate, further research on evidence‐based treatments for PTSD and depression in refugee torture survivors is warranted.     

Conscientiousness,Its Facets,and the Prediction of Job Performance Ratings: Evidence against the narrow measures

This study empirically tested the predictions of the three basic perspectives on the bandwidth debate about the relationship between personality and job performance, regarding the validity of conscientiousness and its facets. The sample consisted of 226 police officers. Conscientiousness and three facets (order, industriousness, and self‐control) were correlated with three performance criteria (overall job performance, task performance, and orderliness). A Schmid–Leiman transformation made it possible to residualize the variance of the facets and to isolate their unique contribution to the prediction of performance measures. The results showed that conscientiousness predicted the three criteria (true validities of.25,.28 and.37, respectively) and that the facets neither predicted job performance nor showed incremental validity over conscientiousness. Finally, the implications of the findings for theory and practice are commented on, and future research is suggested.     

Age-Correlated Incremental Consideration of Velocity Information in Relative Time-to-Arrival Judgments

One hundred fifty-one children and 43 adults judged which of 2 cartoon birds would be the first to arrive at a common finish line. Objects moved unidirectionally along parallel trajectories, either at the same or different speeds, and disappeared at different distances from the goal. Overall, 9–10-year-old children performed as well as adults, but 4–5- and 6–8-year-olds erred significantly more often. On trials for which distance to goal at disappearance was a valid cue, 4–5-year-olds scored 80% correct, and no differences were seen between 6–10-year-olds and adults. On the opposite type of trials, where the trailing bird would win the race, only adults retained their level of performance, and all age groups differed markedly. Findings suggest a gradual developmental transition from a distance-based to a time-based understanding of the task.     

Thresholds of Illumination for the Visual Discrimination of Direction of Movement and for the Discrimination of Discreteness

Currently, relatively little is known about what drives the choice of limb for goal-oriented reaching. Traditionally, the explanation has been tied predominately to motor dominance as manifested in handedness. This article offers data and an argument suggesting that handedness can be modified by attentional (spatial) information. Although motor dominance may be the controlling factor in the programming and execution of reaching movements at the midline and hemispace ipsilateral (same side) to the dominant limb, attentional information alters the programming of movements in what would be contralateral space. The general trend of behavior is characterized by reaching on the same side as the stimulus, in ipsilateral fashion, a phenomenon explained by kinesthetic efficiency and hemispheric bias.
