Dimensionale versus kategoriale Klassifikation von Pers?nlichkeitsst?rungen

The classification systems DSM-IV and ICD-10 are characterized by a categorical conception of personality disorders. This perspective has long been criticized for a number of reasons and a dimensional perspective plays a major role in the debate. For both approaches, advantages and disadvantages can be discussed and a categorical-dimensional hybrid approach will most likely be established in the revised classification systems ICD-11 and DSM-V. An integration of a categorical and a dimensional??quantifying??perspective has always been a standard in the field of forensic psychiatric assessment. A general hybrid approach of defining personality disorders appears suitable, promising and feasible.     

Aktuelle Aspekte des Gefängnissuizids

Suicides present a major complication during imprisonment and contribute essentially to the high mortality rate of prisoners. All international studies found increased suicide rates among prisoners in comparison to the general population. This article reviews general and individual risk factors for suicide in prison and possible contributing specific stress factors during imprisonment. The main results of the analysis of the European Annual Prison Statistics from 1997 to 2007 are presented referring to macrostructural determining risk factors for suicide in prison. Measurements and prevention strategies are briefly discussed.     

Impulsive responses in children with conduct disorder and borderline intellectual functioning.

The study is designed to investigate response inhibition in children with conduct disorder and borderline intellectual functioning. To this end, children are compared to a normal peer control group using the Alertness test. The test has two conditions. In one condition, children are instructed to push a response button after a visual "go" signal is presented on the screen. In a second condition the "go" signal is preceded by an auditory signal, telling the child that a target stimulus will occur soon. Compared to the control group, the group carrying the dual diagnosis made many preliminary responses (responses before the presentation of the "go" signal), especially in the condition with an auditory signal. This impulsive response style was controlled for attention deficit/hyperactivity disorder characteristics of the children.     

When conveying a message may hurt the relationship: Cultural differences in the difficulty of using an answering machine

Cultures differ in their emphasis on the two core functions of communication, conveying information and maintaining the relationship. Because answering machines primarily serve the former function, their use may show cultural differences. Leaving a message is cognitively more taxing for Japanese than Americans, as indicated by poorer performance on a secondary task (Study 1). This performance decrement reflects that Japanese allocated more cognitive resources to tailoring the message to the recipient, consistent with their culture’s higher emphasis on relationship goals. Such cross-cultural differences were not restricted to the laboratory situation. Although equally likely to own an answering machine, Japanese reported a higher rate of hanging up when reaching an answering machine than Americans (Study 2). The difficulties that Japanese experience when leaving a message on an answering machine are partly due to the lack of feedback channel. Theoretical implications are discussed.     

The Effect of Corporate Social Responsibility (CSR) Activities on Companies With Bad Reputations

Based on theories of attribution and suspicion, three experiments highlight the mediating role of perceived sincerity of motives in determining the effectiveness of CSR activities. CSR activities improve a company's image when consumers attribute sincere motives, are ineffective when sincerity of motives is ambiguous, and hurt the company's image when motives are perceived as insincere. Variables affecting perceived sincerity include the benefit salience of the cause, the source through which consumers learn about CSR, and the ratio of CSR contributions and CSR‐related advertising. High benefit salience of the cause hurts the company, in particular when consumers learn about it from a company source. This backfire effect can be overcome by spending more on CSR activities than on advertising that features CSR.     

The influence of theta transcranial alternating current stimulation (tACS) on working memory storage and processing functions

The study aimed to explore the role of the fronto-parietal brain network in working memory function—in temporary storage and manipulation of information. In a single blind sham controlled experiment 36 respondents solved different working memory tasks after theta transcranial alternating current stimulation (tACS) was applied to left frontal, left parietal and right parietal areas. Both verum tACS protocols stimulating parietal brain areas (target electrodes positioned at location P3, or P4) had a positive effect on WM storage capacity as compared with sham tACS, whereas no such influence was observed for the stimulation of the left frontal area (target electrode positioned at location F3). A second finding was that left parietal theta tACS had a more pronounced influence on backward recall than on forward recall, which was not related to task content (spatial or verbal). The influence of theta tACS on WM executive processes was most pronounced for right parietal stimulation. The results are discussed in the broad theoretical framework of the multicomponent model of working memory.     

Inferring the popularity of an opinion from its familiarity: a repetitive voice can sound like a chorus

Despite the importance of doing so, people do not always correctly estimate the distribution of opinions within their group. One important mechanism underlying such misjudgments is people's tendency to infer that a familiar opinion is a prevalent one, even when its familiarity derives solely from the repeated expression of 1 group member. Six experiments demonstrate this effect and show that it holds even when perceivers are consciously aware that the opinions come from 1 speaker. The results also indicate that the effect is due to opinion accessibility rather than a conscious inference about the meaning of opinion repetition in a group. Implications for social consensus estimation and social influence are discussed.
