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.     

Sleeping in safe places: An experimental investigation of human sleeping place preferences from an evolutionary perspective

Although humans spend a third of their life asleep, their choice of sleeping places has so far been little investigated both theoretically and empirically. We address this issue from the perspective of evolutionary psychology. Our basic assumption is that humans have an evolved preference for safe sleeping places, that is, those that promise protection against potential aggressors and nighttime predation. Several testable predictions were derived from this assumption concerning the preferred location of the bed in a sleeping room. Specifically, we predicted that people prefer sleeping places that allow them to view the entrances to the sleeping room (doors and windows) from a distance while remaining concealed from the entrances themselves. To test these hypotheses, 138 participants were asked to arrange a bed and other pieces of furniture on floor plans that were experimentally manipulated with respect to the direction in which the door opened and the presence of a window. In agreement with predictions, participants predominantly positioned the bed in a way that (a) allowed them to see the door, (b) was as distant as possible from the door, and (c) was on the side of the room toward which the door opened. In addition, the positioning of the bed was influenced as predicted by the presence of a window.     

Work engagement accumulation of task, social, personal resources: A three-wave structural equation model

Drawing on Conservation of Resources Theory and previous research on work engagement, the present study investigates gain spirals between employees' engagement and their task, social, and personal resources. It focuses on the key resources of job control, positive work relationships, and active coping behavior. In a three-wave design, work engagement (T2) is suggested to function both as an outcome and antecedent of these resources, so that engagement mediates indirect longitudinal effects of initial (T1) on subsequent (T3) resources. Item-level structural equation modeling supported our hypotheses in a three-wave panel (N = 416) of hospital physicians with measurement intervals of 14 and 19 months. Connections between engagement research and other evolving perspectives in organizational research are highlighted. Unique contributions of the present study and their implications for further research and practice are discussed.     

“And yet it moves” or why grammar overrides frequency: a reply to Kempen and Harbusch

We show that Kempen and Harbusch's (Cognition (2003) this issue) arguments against our claims cannot be upheld. On the one hand, their alternative account of our data that is based on the availability of constructions with object-experiencer verbs is not compatible with the literature on the processing of these types of sentences in German. Moreover, their allegation that we failed to conduct an accurate corpus count is simply a misreading of our paper. Insofar, the commentary in no way casts doubt on our claim that grammatical regularities override frequency during online comprehension.     

Optimization of Social Structure in Business Networks by Grid-Technique and Polyhedral Analysis

This article deals with the definition and analysis of the social, communicative, and cognitive abilities of managers acting in network contexts. We can tackle the complex relationship of role demands and role adoption by applying grid-technique and polyhedral analysis. We can gather data on context-specific personal constructs with the help of the grid technique. Using these data, polyhedral analysis shows how defined persons are integrated into the relation structures within a network. Beyond this, we show if and how relevant criteria such as holes, connectivity, and eccentricity can be employed for analyzing problems stemming from personnel management. Based upon the applied methods, it is possible to provide information about the relevant structures within networks used in personnel selection and competency development. Decision makers have the task to select among the measures of personnel management. Within the relevant context, these measures should be suited to ensure the stability and efficiency of the network.     

When technology tells you how you drive––truck drivers’ attitudes towards feedback by technology

Behavior based safety approaches have proven effective in reducing accidents in industrial settings, but cannot easily be extended to commercial driving. For considerable periods of working time, truck drivers are alone, and do not interact with peers. It might be possible to use data gathered by new in-vehicle technology to provide real-time and post-shift feedback to drivers about their driving behavior. This paper reports the results of focus group interviews conducted with subject matter experts from the trucking industry (truck drivers, supervisors, managers, and other involved persons, such as insurance industry safety professionals). The focus groups discussed safety critical behaviors in commercial driving, the best way to provide feedback to truck drivers, and benefits of feedback by technology as well as concerns drivers and operators may have regarding monitoring and feedback systems. The focus group discussions showed that, in general, drivers would like to receive more feedback and that feedback by technology is acceptable, if designed and implemented properly. In addition, the participants had many suggestions on how to properly design and implement such systems.     

Complex prospective memory in children with ADHD.

The ability to remember intentions (prospective memory) is fundamental to the organization of goal-directed actions in everyday life. Successful prospective remembering involves forming, retaining, initiating, and executing an intention. Although previous research has demonstrated prospective memory impairments in children with attention deficit/hyperactivity disorder (ADHD), this has largely focused on the intention initiation and execution stages. In this study, we investigate the performance of 20 children with ADHD and 20 matched controls at each of the four stages of prospective memory, using a computer multitask paradigm. Results suggest that children with ADHD may demonstrate difficulties forming delayed intentions, as indicated by impulsive planning, and that this may have further implications for the retention and implementation of these delayed intentions. While children with ADHD showed comparable multitask switching, this appeared to be at the expense of intention execution as they made more performance errors than controls. Implications for day-to-day functioning are discussed.     

New Perspectives on an Old Debate: Friedrich Schleiermacher's Essay on Election

Abstract: This article analyses Schleiermacher's essay on election, which has not received the attention it deserves. I argue that it presents a significant advance in the debate about unconditional grace and the relation between redemption and predestination. While Schleiermacher defends the Augustinian‐Calvinist view of election, he criticizes the ideas of double predestination and eternal damnation (for the unbelievers). Thus, he wants to provide a new basis for Lutherans and Calvinists to settle or, at least, reconsider their longstanding controversy over the matter. After the publication of the essay in 1819, Schleiermacher's doctrine of election remained unchanged, except for minor modifications.     

Are country level prevalences of rule violations associated with knowledge overclaiming among students?

Cultural norms of behaviour influence desirable and problematic behaviours of individuals. In particular, cultural norms should influence individuals' dishonesty. In a recent Nature study, prevalence of rule violations was introduced as a new country‐level measure of behavioural norms. However, information on individuals' actual honesty was not available due to characteristics of the experimental design. Overcoming this limitation, we show that country‐level behavioural norms are related to individual‐level knowledge overclaiming behaviour (i.e., claiming to know concepts that do not exist, a measure of individuals' actual behavioural dishonesty) among 290,954 students from 57 countries (from the 2012 PISA study). Our study represents a crucial test of the argument that cultural norms influence individual's behaviour and of the validity of the measurement of countries' prevalences of rule violations. These results imply that shaping the behaviour of today's students may result in new behavioural norms that emphasise honesty and rule adherence more strongly.     

Zur Prävalenz von Depersonalisation und Derealisation in der stationären Psychotherapie

Depersonalization (DP) and derealization (DR) remain poorly recognized in clinical routine. Active exploration through structured interviews is strongly recommended, because patients rarely describe spontaneously their experiences with DP/DR. 143 psychosomatic, first-admission inpatients were interviewed about the 1-month prevalence of DP/DR using the Structured Clinical Interview for DSM-IV dissociative disorders. Additionally, the German questionnaires of the Cambridge Depersonalization Scale, the Dissociative Experiences Scale, the SCL-90-R and the Inventory of Interpersonal Problems were used. In the sample we found a prevalence of 23.1% (N=33) for depersonalization-derealization syndrom (ICD-10 F48.1) and 7% (N=10) for secondary pathological DP/DR. A total percentage of 62.9% reported DP/DR to some degree or other. There was a noticeably high co-occurrence of anxiety disorders in patients with pathological DP/DR. Patients with pathological DP/DR were generally more impaired, suffered many more interpersonal problems and were particularly characterized by introversion. Considering the high prevalence of this phenomenon, more attention should be paid to DP/DR in routine diagnostic procedures, treatment and research.
