Perceptions of morality and competence in (non)interdependent games

Individuals’ actions and their stated beliefs affect how others perceive them. In a prisoner’s dilemma, a defector who expects others to cooperate is perceived as less moral than a defector who expects others to defect; a cooperator who expects others to defect is perceived as less competent than a cooperator who expects others to cooperate (Experiment 1). This pattern suggests that in a context of interdependence, a stated expectation that the behavior of others will resemble one’s own may protect one’s social reputation. When outcomes are not interdependent, expectations do not moderate the effects of behavior on reputation (Experiment 2). In such a context, inductive reasoning is sufficient to explain social projection. Both types of results are replicated in a modified N-person social dilemma (Experiment 3), further validating the inductive-reasoning hypothesis.     

Psychiatrische Versorgung im europäischen Strafvollzug

Objective and methods:

We analysed administrative national data regarding mental health care and psychiatric prevalence in the penitentiary systems of 24 European countries. Data was provided by national experts via questionnaire.

Results:

There is a mixed approach for prison mental health care in European countries that either rely on separated psychiatric prison services or collaborate with specialized forensic or general mental health care services. Care provision in general is assessed as deficient. At all decisive points of detention, adequate screening or diagnostic routines are lacking. As a consequence, nothing is known about the prevalence of mental disorders in European prisons. At the moment, only a very limited number of secondary indicators are available for describing the problem.

Conclusion:

There is an urgent need for improving the reporting routines on mental disorders in prison inmates as a first step for improving substantially the mental health care provision for prisoners in European countries.     

Introduction to Bayesian Inference for Psychology

We introduce the fundamental tenets of Bayesian inference, which derive from two basic laws of probability theory. We cover the interpretation of probabilities, discrete and continuous versions of Bayes’ rule, parameter estimation, and model comparison. Using seven worked examples, we illustrate these principles and set up some of the technical background for the rest of this special issue of Psychonomic Bulletin & Review.

Ethnic Minorities in the Mass Media: How Migrants Perceive Their Representation in Swiss Public Television

Communication research highlights deficiencies in the media’s representation of migrants. The study at hand analyzes these deficiencies from the perspective of the migrants concerned: How do they perceive their representation in the media, especially on television? And how do they assess the perceived situation with regard to immigrant integration? This topic has been examined in a qualitative pilot study based on six group discussions amongst migrants and Swiss citizens with an immigration background in the German-, French-, and Italian-speaking parts of Switzerland. The results show a high discrepancy between the desire for more presence and participation on the one hand, and the wish to stand in the spotlight less often, on the other hand.     

The scope and precision of specific temporal expectancy: evidence from a variable foreperiod paradigm

Recent evidence from choice response time experiments with variable foreperiods (FPs) has shown that temporal expectancy can be event specific. When a certain target appears particularly frequent after one certain FP, participants tend to expect that target after that FP. This typically results in best performance for that target when it appears after that FP. In the present study, we investigated how temporally precise event-specific temporal expectancy is, and in which range of FPs it can be found. Two target stimuli were asymmetrically distributed over two "peak-FPs" and were equally distributed over 13 additional FPs. Event-specific expectancies were found for peak-FP pairs of 500/1,100?ms and 300/500?ms. Furthermore, the event expectancies generalized to a wide range of nonpeak FPs surrounding the peak FPs.     

When the whole is more than the sum of its parts: Group motivation gains in the wild

Whereas negative effects of groups on individual motivation have been reported for many years, recent research has begun to show when and why working in a group can produce motivation gains compared to individual work. So far, this evidence has been limited to laboratory settings and rather simple tasks. Using data from swimming competitions at the 2008 Olympics, evidence is presented that motivation gains in groups also occur in field settings with more complex tasks. Based on an instrumentality × value approach, we expect that late positions in a relay trigger motivation gains in groups due to an increase in perceived indispensability for the group outcome. This idea has been initially tested in a pilot study with competitive swimmers, demonstrating that perceived indispensability for the relay outcome indeed increases with later serial positions in a relay. Moreover, the main study with data from the 2008 Olympics revealed performance times consistent with this pattern of indispensability perceptions: while starting swimmers in the swimming relays performed at similar levels as in their individual competitions, swimmers at the later positions showed higher performance in the relay compared to their individual competition heats.
