Seelische Entwicklung in virtuellen Welten

Electronic screen media such as television, computers and video game consoles have to a large extent replaced the natural living human environment—and most evidently the world of children and teenagers in a measurable way. This impact is the result not only of the ubiquitous presence of screen media but also of the differing properties of the programs, which display a toxic potential that varies from case to case. It appears prudent, therefore, to classify electronic media as invasive or non-invasive according to their toxic potential. It is now possible to describe the clinical results of these cataclysmic changes in the lives of children and teenagers with a fair degree of precision even from a psychoanalytical perspective. The consequences in the form of educational and psychotherapeutic actions can be derived directly from these findings.     

Overcoming fixed mindsets: The role of affect

When there is an established strategy to solve a problem, we often approach the problem with a mindset that makes us blind for more efficient solutions. We examined the role of affect in overcoming such blinding effects of mindsets. As positive affect is known to broaden and negative affect to narrow thought–action repertoires, we speculated that positive affect facilitates and negative affect impedes the overcoming of a current mindset. To induce a mindset, participants initially solved 60 similar problems which were only solvable using the same complex strategy. After a short break in which positive or negative affect was induced, participants continued to work on the problems. Critically, there now was an additional simple way to solve the problems. Participants experiencing positive affect were more likely to detect the simple solution than participants experiencing negative affect. These findings reveal that affect modulates how much we are constrained by current mindsets.     

The effects of affective states on the formation of performance expectancies

Positive vs. negative affective states are associated with the use of broad vs. specific knowledge structures. These findings were applied to the field of performance expectancies. It was predicted that individuals with positive mood should infer their performance expectancies concerning a specific task from their general self-concept, whereas given negative mood, performance expectancies should be inferred from the relevant specific self-concept. In an experiment, positive vs. negative mood was induced in 158 university students. General and specific self-concepts were assessed. Furthermore, we assessed task-specific performance expectancies and task performance. Specific self-concept was predictive of expectancies given negative mood, whereas with positive mood, expectancies could only be predicted on the basis of the general self-concept. Furthermore, mean expectancies were higher and less accurate with positive mood. The results are in line with the theoretical predictions. They underline that affective states also influence the formation of motivational variables like performance expectancies.     

Cognitive mediation of intervention effects on physical exercise: Causal models for the adoption and maintenance stage

Objective: To investigate how the effects of a group-based intervention program (MoVo-LISA) on exercise behaviour were mediated by cognitive variables. Different causal models mapping the short-term (adoption) and long-term (maintenance) intervention effects were tested using path analyses.

Design: N?=?220 in-patients of a rehabilitation clinic were assigned to an usual care or intervention group (quasi-experimental design). Questionnaire-based assessment was conducted at baseline; discharge; and at six weeks, six months and 12 months post discharge.

Measures: The potential mediator variables were outcome expectations, self-efficacy, strength of goal intention (intention strength), self-concordance, action planning and barrier management.

Results: Observed intervention effects on exercise behaviour (p?<?0.05) were mediated by intention strength at the adoption and maintenance stages, by action planning only at the adoption, and by barrier management only at the maintenance stage. Self-efficacy and outcome expectations were only indirectly involved in these mediations by affecting intention strength and self-concordance.

Conclusion: This is the first study to track the cognitive mediation processes of intervention effects on exercise behaviour over a long time-period by differentiating the adoption and maintenance stages of behaviour change. The findings emphasise the importance of deconstructing intervention effects (modifiability vs. predictive power of a mediator) to develop more effective interventions.

Always look on the broad side of life: happiness increases the breadth of sensory memory

Research has shown that positive affect increases the breadth of information processing at several higher stages of information processing, such as attentional selection or knowledge activation. In the present study, we examined whether these affective influences are already present at the level of transiently storing incoming information in sensory memory, before attentional selection takes place. After inducing neutral, happy, or sad affect, participants performed an iconic memory task which measures visual sensory memory. In all conditions, iconic memory performance rapidly decreased with increasing delay between stimulus presentation and test, indicating that affect did not influence the decay of iconic memory. However, positive affect increased the amount of incoming information stored in iconic memory. In particular, our results showed that this occurs due to an elimination of the spatial bias typically observed in iconic memory. Whereas performance did not differ at positions where observers in the neutral and negative conditions showed the highest performance, positive affect enhanced performance at all positions where observers in the neutral and negative conditions were relatively "blind." These findings demonstrate that affect influences the breadth of information processing already at earliest processing stages, suggesting that affect may produce an even more fundamental shift in information processing than previously believed.     

Peripheral pain enhances the effects of incentive downshifts

Physical pain (induced by tissue damage) and psychological pain (induced by surprising incentive loss) share a set of common neural substrates, but little is known about their interactions. The present research studied such interactions using the formalin test to induce physical pain and consummatory successive negative contrast (cSNC) to induce psychological pain. In the formalin test, animals receive an intradermal injection of formalin (1%) in a hind paw. In cSNC, rats with free access to 32% sucrose show a sharp suppression of drinking behavior after a downshift to 4% sucrose, compared to rats that always receive 4% sucrose. In Experiment 1, formalin administration before the first and second 32-to-4% sucrose downshift trials enhanced cSNC. In Experiment 2, a similar treatment before the first downshift trial after a 16-to-4% sucrose downshift, which normally produces little or no evidence of cSNC, significantly increased cSNC. In Experiment 3, using a 32-to-4% sucrose downshift procedure similar to that of Experiment 1, no effects were observed following formalin administration immediately after Trial 11. Thus, no evidence was found that the effects of physical pain on cSNC were caused by changes in memory consolidation. The procedures used in these experiments offer a new approach to study the neural substrates of interactions between physical and psychological pain.     

How affective states, task difficulty, and self-concepts influence the formation and consequences of performance expectancies

Positive versus negative affective states are associated with the use of broad versus specific knowledge structures. We predicted that specific self-concepts and task difficulty would affect performance expectancies only for individuals in a negative mood; for individuals in a positive mood, only the general self-concept, but not task difficulty, would affect performance expectancies. In an experiment, we manipulated task difficulty and mood, and we assessed self-concepts, performance expectancies, and task performance. The expected interactions for the formation of performance expectancies (mood × general self-concept, mood × specific self-concept, mood × difficulty) were found. Concerning the consequences of performance expectancies, we predicted that expectancies would affect actual performance only if the task was difficult and if task difficulty was taken into account when the expectancy is generated. This hypothesis was supported: The relationship between performance expectancies and actual performance was significant only for difficult tasks and given negative mood.     

No conflict control in the absence of awareness

Introduction  

In the present study we tested whether control over the impact of potentially conflicting information depends on awareness of that conflicting information.
