Watching pornographic pictures on the Internet: role of sexual arousal ratings and psychological-psychiatric symptoms for using Internet sex sites excessively

Excessive or addictive Internet use can be linked to different online activities, such as Internet gaming or cybersex. The usage of Internet pornography sites is one important facet of online sexual activity. The aim of the present work was to examine potential predictors of a tendency toward cybersex addiction in terms of subjective complaints in everyday life due to online sexual activities. We focused on the subjective evaluation of Internet pornographic material with respect to sexual arousal and emotional valence, as well as on psychological symptoms as potential predictors. We examined 89 heterosexual, male participants with an experimental task assessing subjective sexual arousal and emotional valence of Internet pornographic pictures. The Internet Addiction Test (IAT) and a modified version of the IAT for online sexual activities (IATsex), as well as several further questionnaires measuring psychological symptoms and facets of personality were also administered to the participants. Results indicate that self-reported problems in daily life linked to online sexual activities were predicted by subjective sexual arousal ratings of the pornographic material, global severity of psychological symptoms, and the number of sex applications used when being on Internet sex sites in daily life, while the time spent on Internet sex sites (minutes per day) did not significantly contribute to explanation of variance in IATsex score. Personality facets were not significantly correlated with the IATsex score. The study demonstrates the important role of subjective arousal and psychological symptoms as potential correlates of development or maintenance of excessive online sexual activity.     

Transferring More than Learned in Training: Employees' and managers' (over)generalization of skills

Across two studies, we examine the extent to which individuals accurately report their learning and transfer in a training context. In Study 1, we examine self (subordinate) and supervisory estimations of training transfer, 6–12 weeks after employees (subordinates) attended training in an organization in the United States. Using ratings of skills unrelated to training programs attended, we compared managers' and employees' ratings to determine the extent to which respondents report skill overgeneralization. Individual differences and skill visibility were examined as predictors of training transfer overgeneralization. Subordinates, particularly those high on conscientiousness, agreeableness, and emotional stability, are more likely to report transfer in areas not covered in training. Conversely, when managers rate skills, which are used in their subordinates' day‐to‐day activities (more observable, visible, or transparent skills), training transfer estimates are more accurate. In Study 2, we determine that conscientiousness is the main factor driving raters' overgeneralization (for self‐ratings), and we further demonstrate that other personality dimensions – insecurity and perfectionism – accentuate the influence of conscientiousness on trainees' overgeneralization. From a practical standpoint, employers need to be aware of potential for biases in training transfer ratings when evaluating training transfer, particularly for employees with specific personality characteristics and for those who are in jobs with low skill visibility.     

Personal characteristics,resources, and environment as predictors of business survival

Although new venture success is frequently investigated in entrepreneurship, economics, and psychology, the studies published to date vary widely in their theoretical basis, study design, and research methodology. Based on organizational life‐cycle theory and interactional personality theory, this longitudinal study analyses predictors of venture survival. Of 354 small business owners observed over 8 years, 283 (79.9%) still had active businesses at the end of the observation period. A survey instrument was developed to measure the relevant characteristics of the entrepreneurs, their resources, and the environment. Logistic regression models predicting medium‐ and long‐term business survival included these characteristics and the interactions between them entered stepwise as blocks. Startup decisions (line of business, type, and size of planned business) were used as control variables. Much of the variance is explained by our research model (Nagelkerkes R²=.36 for survival at 4 years, and .33 for survival at 8 years). Although long‐term business survival is predicted by the individual variables of startup size and social capital (networks), a larger part of the variance is explained by environment/resource interactions.     

The effect of the driving activity on target detection as a function of the visibility level: Implications for road lighting

The Small Target Visibility model used in road lighting design is based on a strong simplification of the driving task. To specify the driver’s visibility needs in a way consistent with state-of-the-art lighting engineering practice, a field experiment was designed in order to investigate target detection performances, comparing driver and passenger status conditions. Sixteen target visibility levels (VL) were used. In the driver status, 34 participants had to press a button as soon as they detected the target stimulus placed on the experimental lighted section. In the passenger status, the same participants had to detect the target stimulus while the experimenter drove. The results show that the passengers’ performances (detection distance) were higher than the drivers’ performances (p = .0014). Furthermore, the higher the VL, the higher the detection distance (p < .0001). These results lead up to modify the reference scenario in order to take into account human factor components for road lighting design.     

Effectiveness and cost offset analysis of group CBT for hypochondriasis delivered in a psychiatric setting: an open trial

Hypochondriasis is highly prevalent in medical settings, has detrimental effects for affected individuals, and is associated with high societal costs. Although cognitive behavior therapy (CBT) has been shown to be effective in the treatment of hypochondriasis, it is not widely available because of a lack of properly trained therapists. Therefore, it is essential to evaluate therapy forms that require less therapist time. The authors investigated the effect and economic impact of group CBT delivered in a psychiatric setting among 24 people with hypochondriasis. A within-group design with prolonged baseline was used, and all participants received 10 weeks of group-based treatment. The primary outcome measures were the Health Anxiety Inventory and the Illness Attitude Scales. Results indicate significant improvement on both measures at posttreatment and 6-month follow-up (Cohen's d = 1.03-1.72). Medical and nonmedical costs were substantially lowered. The authors conclude that group-based CBT delivered in a psychiatric setting is an effective and potentially highly cost-effective treatment for hypochondriasis.     

Tatbilder schizophrener und wahnhafter Täter

Besides the ongoing discussion on whether persons with schizophrenia have a higher prevalence of criminal offences, it is also of special interest for the prognosis in this group of offenders whether there is a causal relationship between the schizophrenic disease and the type of delinquency. For the construction of causal relationships it is important to determine a typology of offences committed by schizophrenic persons. This article deals with the problem by analyzing the offences of 133 patients diagnosed with schizophrenia, schizo-affective and delusional disorders at the Landschaftsverband Westfalen-Lippe (LWL) Center for Forensic Psychiatry in Lippstadt.     

Auditory color constancy: Calibration to reliable spectral properties across nonspeech context and targets

Brief experience with reliable spectral characteristics of a listening context can markedly alter perception of subsequent speech sounds, and parallels have been drawn between auditory compensation for listening context and visual color constancy. In order to better evaluate such an analogy, the generality of acoustic context effects for sounds with spectral-temporal compositions distinct from speech was investigated. Listeners identified nonspeech sounds—extensively edited samples produced by a French horn and a tenor saxophone—following either resynthesized speech or a short passage of music. Preceding contexts were “colored” by spectral envelope difference filters, which were created to emphasize differences between French horn and saxophone spectra. Listeners were more likely to report hearing a saxophone when the stimulus followed a context filtered to emphasize spectral characteristics of the French horn, and vice versa. Despite clear changes in apparent acoustic source, the auditory system calibrated to relatively predictable spectral characteristics of filtered context, differentially affecting perception of subsequent target nonspeech sounds. This calibration to listening context and relative indifference to acoustic sources operates much like visual color constancy, for which reliable properties of the spectrum of illumination are factored out of perception of color.
