Frustration of Life Goals Mediates the Negative Effect of Unemployment on Subjective Well-Being

The present study investigated whether unemployment influences the importance and the realization of life goals and whether a reduced realization of life goals mediates the negative effect of unemployment on subjective well-being. A sample of 256 employed and unemployed German adults was studied with scales measuring six different life goal domains (power, achievement, variety, altruism, intimacy, affiliation). Only weak differences between unemployed and employed people were found for importance ratings of life goals. However, current realization of life goals, particularly of agency goals such as power, achievement and variety, was significantly lower among unemployed persons than among employed persons. Thus, unemployment did not change the goals people wanted to achieve in their lifetime, but it inhibited the success of these strivings. Furthermore, current realization of life goals was found to be a mediator of the detrimental effect of unemployment on life satisfaction and positive/negative affect.     

Teaching multiply controlled intraverbals to children and adolescents with autism spectrum disorders

Reciprocal conversations, instructional activities, and other social interactions are replete with multiply controlled intraverbals, examples of which have been conceptualized in terms of conditional discriminations. Although the acquisition of conditional discriminations has been examined extensively in the behavior‐analytic literature, little research has evaluated procedures to establish multiply controlled intraverbals. Thus, the purpose of this investigation was to evaluate the effects of procedures based on conditional discrimination training on the acquisition of multiply controlled intraverbals with 7 participants who had been diagnosed with autism spectrum disorders. We evaluated the effects of prompt delay with error correction, a differential observing response (DOR), and a DOR plus blocked trials on the acquisition of intraverbals using a multiple baseline design. Accuracy of intraverbal performance increased for at least 1 set of stimuli for all participants under prompt delay with error correction conditions; however, 4 participants required additional teaching (i.e., DOR, modified DOR, modified prompt delay with error correction). Based on these findings, when prompt delay with error correction is not sufficient to establish multiply controlled intraverbals, prompted DORs may be an effective alternative.     

Brain activation on pre-reading tasks reveals at-risk status for dyslexia in 6-year-old children

In this fMRI-study, 6-year-old children considered at risk for dyslexia were compared with an age-/gender-matched control group for differences in brain activation when presented with visual stimuli differing in demands for literacy processing. Stimuli were nameable pictures, brand logos familiar to children, and written words - these were either regularly spelled using early-acquired rules ("alphabetic") or more complex ("orthographic"). Brain responses distinguished between the presentation conditions, as a function of group, within many cortical areas. Activation in the alphabetic and orthographic conditions in the left angular gyrus correlated with individual at-risk index scores, and activation in inferior occipito-temporal regions further indicated differential activation for the two groups related to orthographic processing, especially. Since similar patterns are reported in adult dyslexics when processing written words, it appears that sensitivity to the cortical differentiation of reading networks is established prior to formal literacy training.     

Simulationen in den Sozialwissenschaften

Summary   Simulation in the Social Sciences. Computer simulation—hereafter just called ‘simulation’— more and more is getting an important tool in scientific research and development. Simulations provide powerful means for quite different scientific disciplines, for instance for cosmology as well as for economics, and it seems that they can help to extend the borderline of science. However, from a methodological point of view, besides their benefits one can identify several theoretical problems which can occur in the process of scientific research. Some of these problems shall be discussed and consequences of these problems for the use of simulations shall be outlined.     

Descartes and the Labyrinth of the World

In the Rules the young Descartes likens his method to the thread that guided Theseus. The simile is born of a confidence that he has seen through the art of the followers of Daedalus and this has given him a model of how to unriddle the labyrinth of the world. From the very beginning Descartes had an interest not only in optics, perspective, and painting, but in using his knowledge of them to duplicate some of the effects said to have been created by the thaumaturgic magicians. Anamorphoses and automata not only provided Descartes with examples of deceptive appearance, but also pointed the way to the solution of the riddle they posed. Yet it is precisely the attempt to take this exit from the labyrinth of the world that threatens to lead back into it, as the search for truth is threatened by the infinity of space. To claim absolute truth, the natural philosopher would have to show that the mechanical model he has proposed is the only one that could account for the phenomena in question. This, as Descartes himself is forced to recognize, he is unable to do. Are we back in the labyrinth? Instead of seeing in Descartes's method an Ariadne's thread, Father Bourdin likens that method to Icarus. Annoyed, Descartes ridicules the good Father. But Bourdin's too often empty rhetoric raises a serious question: is Descartes Theseus, Daedalus, or Icarus? At stake is our understanding of the world we live in.     

Fast and frugal versus regression models of human judgement

Following Brunswik (1952), social judgement theorists have long relied on regression models to describe both an individual's judgements and the environment about which such judgements are made. However, social judgement theory is not synonymous with these compensatory, static, structural models. We compared the characterisations of physicians' judgements using a regression model with that of a non-compensatory process model (called fast and frugal). We found that both models fit the data equally well. Both models suggest that physicians use few cues, that they disagree among themselves, and that their stated cue use is discrepant with the models' stated cue use. However, the fast and frugal model is easier to convey to physicians and is also more psychologically plausible. Implications for how social judgement theorists conceptualise the process of vicarious functioning are discussed.
