Jugendliche Sexualstraftäter: Spezialfälle der Prognoseerstellung?

This study compared a sample of 273 juvenile (aged 14 to under 18), 178 adolescent (aged 18 to under 21) and 273 adult (older than 20 years) male sex offenders modus operandi (or MO, the way in which they committed their offenses), frequency of recidivism and predicted recidivism via the static-99. In terms of the frequencies of the MO aspects we found that juveniles and adolescents differed significantly from adult sexual offenders. However, concerning the frequency of sexual violent behaviors, adolescents committed more severe offenses in contrast to the two other groups. The comparison of recidivism rates indicated that adolescent sexual offenders were significantly less likely to commit a new sexual offense, but were considerably more likely to commit a non-sexual violent offense compared to adult sexual offenders. For juvenile offenders, only few static-99 variables were predictive of future recidivism in comparison to the other groups, suggesting that the static-99 may only have a restricted utility in juvenile offenders. Further, juvenile offenders risk levels were found to fall primarily within the medium risk group making individual differentiation of potential risk difficult. It is suggested that additional predictors, which help to differentiate young sexual offenders must be investigated.     

EQ-nomics: Understanding the relationship between individual differences in Trait Emotional Intelligence and entrepreneurship

Past studies highlight the importance of Trait Emotional Intelligence (EI) in the prediction of career success. Given the evidence that trait EI predicts job performance and job satisfaction, it is reasonable to expect this construct to also predict other forms of career success. In this study, we examine whether EI predicts entrepreneurship; that is, whether higher trait EI is linked to entrepreneurial behaviours and entrepreneurial success, and whether any effects of trait EI on entrepreneurship are independent of the personality trait of Core Self-Evaluations, demographic variables, and individual differences in entrepreneurial personality. Results show that trait EI predicts only some entrepreneurial outcomes beyond other variables examined, and with small effect sizes. This suggests that individual differences in entrepreneurship result only in part from inter-personal differences in trait EI. Implications for research and practice are discussed.     

Top-down search for color prevents voluntary directing of attention to informative singleton cues

Visuo-spatial attention can be directed in a top-down controlled way to search for color targets and it can be captured by color contrasts, regardless of color identity. Here we tested whether participants can both search for a particular color target (e.g., red) and make use of a color-contrast cue that predicted the target's most likely position to direct their attention voluntarily. Our results show that this was impossible for the participants. Results support that top-down search for particular colors is incommensurate with directing attention to just any color contrast. The results are discussed in light of the current debates concerning the roles of color and color contrast for visuo-spatial attention.     

Sometimes,often, and always: Exploring the vague meanings of frequency expressions

The article describes a general two-step procedure for the numerical translation of vague linguistic terms (LTs). The suggested procedure consists of empirical and model components, including (1) participants’ estimates of numerical values corresponding to verbal terms and (2) modeling of the empirical data using fuzzy membership functions (MFs), respectively. The procedure is outlined in two studies for data from N = 89 and N = 109 participants, who were asked to estimate numbers corresponding to 11 verbal frequency expressions (e.g., sometimes). Positions and shapes of the resulting MFs varied considerably in symmetry, vagueness, and overlap and are indicative of the different meanings of the vague frequency expressions. Words were not distributed equidistantly across the numerical scale. This has important implications for the many questionnaires that use verbal rating scales, which consist of frequency expressions and operate on the premise of equidistance. These results are discussed for an exemplar questionnaire (COPSOQ). Furthermore, the variation of the number of prompted LTs (5 vs. 11) showed no influence on the words’ interpretations.     

A behavioral task for the validation of a gaze-contingent simulated scotoma

Gaze-contingent displays provide a valuable method in visual research for controlling visual input and investigating its visual and cognitive processing. Although the body of research using gaze-contingent retinal stabilization techniques has grown considerably during the last decade, only few studies have been concerned with the reliability of the specific real-time simulations applied. Using a Landolt ring discrimination task, we present a behavioral validation of gaze-contingent central scotoma simulation in healthy observers. Importantly, behavioral testing is necessary to show whether the simulation impairs foveal processing of visual information. This test becomes even more crucial when researchers are faced with null results in a task performed with the scotoma, as compared with a control condition. It must be ruled out that the lack of behavioral effects results from a type II error caused by improper implementation before conclusions about foveal contributions to the given task may be drawn. In our experiment, the scotoma effectively prevented foveal processing of the visual stimuli, leading to significantly reduced response accuracies, as compared with unimpaired vision. Moreover, the final fixation at the time of the participants’ responses was placed close to the target position in the unimpaired condition, whereas the distance to the target was enhanced with the scotoma, indicating that the observers were not able to discriminate visual target stimuli from distractors, due to the scotoma. The present work presents a validated behavioral testing method for the efficiency of gaze-contingent scotoma simulations, including code for implementation. In addition, solutions for common methodological problems are discussed.     

The ear’s versus the eye’s potential to assess characteristics of numeric data: Are we too visuocentric?

A single experiment studied how effectively information about the central tendency, variability, and shape of numeric data distributions could be conveyed to statistically knowledgeable subjects. The data were summarized by visual histograms, auditory histograms that coded numeric value as pitch on the musical scale, and five-note auditory analogues of a box-whisker display that coded the minimum, quartile, and maximum scores as musical notes. Regression and multidimensional scaling analysis of judgments of dissimilarity between distributions showed that auditory depiction provides a highly effective means of conveying information about distributional characteristies. Auditory depicition may be a useful alternative to traditional visual graphics.     

Endogenous versus exogenous attentional cuing effects on memory

Three experiments were conducted to investigate the influence of early attentional cuing effects on subsequent memory. In an incidental study phase, a cue preceded two simultaneously displayed words. An endogenous cue (row of arrows pointing toward one word) or an exogenous cue (row of stars at the location of one word) indicated which word to read aloud. In a subsequent test phase, memory for these cued and uncued words was measured. In Experiment 1, these attentional manipulations had almost no effect on subsequent implicit memory measured using a speeded reading (naming) test. Experiments 2 and 3 demonstrated that, on an explicit memory test, words were reliably better recognized in the endogenous condition than in the exogenous condition. These results suggest that endogenous attentional cues promote more active processing and hence elaboration of words, assisting their subsequent conscious retrieval.     

Recognition of facial affect in Borderline Personality Disorder

Patients with Borderline Personality Disorder (BPD) have been described as emotionally hyperresponsive, especially to anger and fear in social contexts. The aim was to investigate whether BPD patients are more sensitive but less accurate in terms of basic emotion recognition, and show a bias towards perceiving anger and fear when evaluating ambiguous facial expressions. Twenty-five women with BPD were compared with healthy controls on two different facial emotion recognition tasks. The first task allowed the assessment of the subjective detection threshold as well as the number of evaluation errors on six basic emotions. The second task assessed a response bias to blends of basic emotions. BPD patients showed no general deficit on the affect recognition task, but did show enhanced learning over the course of the experiment. For ambiguous emotional stimuli, we found a bias towards the perception of anger in the BPD patients but not towards fear. BPD patients are accurate in perceiving facial emotions, and are probably more sensitive to familiar facial expressions. They show a bias towards perceiving anger, when socio-affective cues are ambiguous. Interpersonal training should focus on the differentiation of ambiguous emotion in order to reduce a biased appraisal of others.     

Zur Altersabh?ngigkeit von Risikovariablen bei Sexualdelinquenz

Based on a sample of 612 male sex offenders, this study examined the latent dimensions of actuarial risk variables, their age-related development and their age-related relevance for the prediction of sexual recidivism within a follow-up period of 5 years. According to the work of Roberts et al. [25] 8 items from Static-99 and Risk Matrix 2000 were examined for their underlying factor structure. The result was a 3-factor solution, which accounted for 63% of the variance and largely replicated the previous findings by Roberts et al. [25]. Following these authors the three scales sexual deviance, dissociality and detachment were calculated from the risk variables and examined in detail. The analysis revealed an increase in sexually deviant personality traits with advancing age of the offenders at the beginning of the follow-up period. No age-related changes were observed in dissocial characteristics. Concerning the detachment scale a negative correlation with the offenders age was apparent. All three risk scales proved to be prognostically relevant in the total sample. On closer examination, however, only sexual deviance showed prognostic relevance in all age groups. In contrast, dissociality was only relevant for the prediction of sexual recidivism in the older offender groups and detachment only in the younger offender groups.
