Individual differences in metacontrast masking regarding sensitivity and response bias

In metacontrast masking target visibility is modulated by the time until a masking stimulus appears. The effect of this temporal delay differs across participants in such a way that individual human observers' performance shows distinguishable types of masking functions which remain largely unchanged for months. Here we examined whether individual differences in masking functions depend on different response criteria in addition to differences in discrimination sensitivity. To this end we reanalyzed previously published data and conducted a new experiment for further data analyses. Our analyses demonstrate that a distinction of masking functions based on the type of masking stimulus is superior to a distinction based on the target-mask congruency. Individually different masking functions are based on individual differences in discrimination sensitivities and in response criteria. Results suggest that individual differences in metacontrast masking result from individually different criterion contents.     

Mood-related changes in construing self and others

Two repertory grids were administered to 31 Canadian undergraduates (20 women and 11 men) in which they rated themselves and 10 personal acquaintances on 11 supplied constructs. For the initial (baseline) grid they followed neutral instructions. For the second grid, they rated the same figures while listening to happy music and attempting to recall pleasant memories. The results from both grids closely approximated a set of theoretical predictions derived from a model of interpersonal judgment by Lefebvre, Lefebvre, and Adams-Webber (1986) within the framework of personal construct theory.     

Effects of a flexible work-time design on employee- and company-related aims

This article addresses the effects of flexible work-time designs on employee- and company-related aims. Using objective and self-reported quantitative and qualitative data the current study examines the effects of a flexible work-time design that was introduced in a service company in Germany. Building on the learning hypothesis of the job demands?–?control model, we predicted that a highly flexible work-time design that provides employees with high demands but at the same time also with a high degree of autonomy, and self-determination over their working time leads to positive effects on employee's personal development and learning opportunities. The results supported this hypothesis. However, in addition to employee-related benefits the results also suggested benefits for the company, such as an increase in adherence to company goals. Moreover, the objective data showed a lower degree of absenteeism and higher work quality compared to the control group working with the traditional work-time design. Theoretical and practical implications are discussed.     

Psychosomatik der Kopfschmerzen

Headaches are subdivided into primary and secondary headaches according to the classification of the International Headache Society. While primary headaches represent the disease itself, secondary headaches are a manifestation as symptoms of another primary disease. This results in different therapeutic approaches so that secondary headaches are initially treated according to the actual cause of the headache. In contrast primary headaches have no further causes and necessitate fundamentally different treatment in comparison to secondary headaches. The psychosomatics integrate somatic procedures with psychiatric and social processes. This integration forms the basis of the biopsychosocial model which has the great advantage of being able to offer several approaches to psychiatric processes and accomanying alterations. For primary headaches psychotherapeutic strategies and modifications in the social environment of the patient can be applied in addition to medicinal (i.e. biological somatic) treatment procedures, in order to be able to positively influence the underlying disease. This article presents the most important primary headache diseases, migraine and tension-type headache and demonstrates treatment options which can be used in accordance with the biopsychosocial model presented.     

Construal Level and Social Exclusion: Concrete Thinking Impedes Recovery From Social Exclusion

Social exclusion is a painful experience. Recent research has shown, however, that coping with exclusion can be facilitated by favorable conditions. In the current research, we investigated whether construal level affects recovery from social exclusion. We hypothesized that an abstract vs. concrete mindset would moderate coping with exclusion. Indeed, lower compared to higher concrete thinking (Study 1) and abstract compared to concrete thinking (Study 2) bolstered the basic need of belonging when excluded. Priming of abstract thinking, moreover, increased participants’ sense of belonging both in response to exclusion and inclusion relative to no priming (Study 3). Our results are the first to establish a relationship between construal level and social exclusion, thereby suggesting an alleviating “abstraction discount” effect for the consequences of social exclusion.     

The effect of construal level on risk‐taking

In a series of studies, we examined the influence of people's mind‐set (construal level (CL): abstract versus concrete) on their risk‐taking behavior. We measured differences in CL (study 1, CL as trait) and manipulated CL (studies 1–5, CL as state) with different priming methods, which were unrelated to the dependent variable of risk‐taking behavior (studies 1, 3, 4, and 5: Balloon Analog Risk Task; study 2: Angling Risk Task). In all studies, abstract CL resulted in greater risk‐taking compared with concrete CL, which led to lower risk‐taking. Risky and safe game strategies mediated the CL effect on risk‐taking. A concrete mind‐set increased the safe game strategy, whereas an abstract mind‐set increased the risky game strategy. Furthermore, different potential mediators were explored (i.e., focus on payoffs and probabilities, prevention versus promotion focus, attention to pros versus cons, and mood). A concrete mind‐set increased prevention strategies and a negative mood when compared with an abstract mind‐set. In turn, an abstract mind‐set increased attention to pros (of an action).

Introspection,mindreading, and the transparency of belief

This paper explores the nature of self‐knowledge of beliefs by investigating the relationship between self‐knowledge of beliefs and one's knowledge of other people's beliefs. It introduces and defends a new account of self‐knowledge of beliefs according to which this type of knowledge is developmentally interconnected with and dependent on resources already used for acquiring knowledge of other people's beliefs, which is inferential in nature. But when these resources are applied to oneself, one attains and subsequently frequently uses a method for acquiring knowledge of beliefs that is non‐inferential in nature. The paper argues that this account is preferable to some of the most common empirically motivated theories of self‐knowledge of beliefs and explains the origin of the widely discussed phenomenon that our own beliefs are often transparent to us in that we can determine whether we believe that p simply by settling whether p is the case.     

Aggression Predicts Changes in Peer Victimization that Vary by Form and Function

Peer victimization is predictive of serious problems in adjustment, especially among children who are both victimized and aggressive. This study investigated how different types of aggression contribute to later victimization. Specifically, we examined prospective relationships between the types of aggression that children perpetrated and the types that they experienced at the hands of others. Trained observers coded schoolyard behavior of 553 children in grades 3–6 during the initial year of a bullying intervention program. Both observed aggression and victimization were specified by form (direct, indirect) and function (proactive, reactive). Total hourly rates of victimization were highest in the upper grades. Direct-reactive aggression uniquely predicted increases in victimization, while direct-proactive aggression predicted decreases, particularly in direct-proactive victimization. Indirect-proactive aggression (e.g., derogatory gossip) predicted increases in indirect-proactive victimization only in the control group. Indirect-reactive aggression and victimization occurred too rarely to detect change. Aggression-victimization relationships did not differ for boys and girls. Discussion considers why children might risk direct reactive aggression in the face of increased victimization. Different sequelae for different forms and functions of aggression highlight the need to resolve theoretical ambiguities in defining proactive and reactive aggression.
