Strategies Aimed at Reducing Gender Differences in Negotiation Are Perceived by Women as Ineffective

Sex Roles - Women often fare worse in negotiations than men. Negotiation researchers, trainers, and policymakers thus aim to find solutions—such as specific strategies for female...     

Appresentation and Simultaneity: Alfred Schutz on Communication between Phenomenology and Pragmatics

In his theory of communication Schutz exhibits a significant tension between two fundamental perspectives, phenomenology and pragmatism, and in the long run he fails to reconcile the contradictory implications these perspectives have with regard to his model of interaction.The main problem seems to be the notion of sense-constitution. Schutz develops two distinguishable accounts of constitution: an egological one and a model based on the phenomenon of direct interaction of empirical subjects. Two key concepts are related to these different modes of constitution: the model of appresentation with regard to language, symbols and signs, and the model of synchronisation as triangulation of streams of consciousness and outward action sequences. They are analyzed as significant for two different methods and two different theories of communication. I propose some reasons for Schutz's insistence on a phenomenological account of the ego and the constitution of sense, and offer a brief sketch of an alternative strategy that is implicit in Schutz's theory.     

Zahnhartsubstanzschäden bei Essstörungen

Eating disorders such as anorexia nervosa and bulimia nervosa lead to several serious physical problems. One possible consequence is acid-related dental erosion. Dental erosion can be identified early and is caused by exogenic (selection of food) and / or endogenic (gastric acid) factors. That is why dentists play an important role in the early identification of eating disorders as well as in the prevention and therapy of dental erosion. They should be important collaborators of psychotherapists. We review characteristic damages to the teeth that are seen in eating disorders as well as preventive and therapeutic interventions. Psychotherapists should be informed about dental problems and preventive strategies to educate their patients.     

Effectiveness and Effects of Promotion Strategies for Behaviour Change: Solar Water Disinfection in Zimbabwe

Solar water disinfection (SODIS) is a sustainable method of water treatment. Despite the simplicity and many advantages of SODIS, past behaviour change campaigns have seen limited success. This study aims to compare intervention strategies in their efficiency in changing behaviour and to analyse which behavioural factors are differentially affected. The following factors were analysed in this study: intention, subjective norm, behavioural control, beliefs, habits, frequency of talking, knowledge and tension. The promotion strategies used in this intervention study were promoters, a pass‐on task, prompts, public commitment and disseminating knowledge with inducing tension. Inhabitants of high‐density areas near Harare, Zimbabwe, were interviewed at different points in time. High SODIS consumption was achieved when the promoter intervention was followed by a memory‐aiding technique such as prompts or public commitment. Consequently, this combined‐intervention strategy increased all behavioural factors and kept them at a high level. A continued pass‐on task alone did not change behaviour and had decreasing effects on several behavioural factors. When the pass‐on task was combined with disseminating knowledge with inducing tension, high SODIS water consumption was also reached, but several behavioural factors stayed at a low level. More effective intervention strategies are identified and discussed.     

Stimulus-response compatibility and sequential learning in the serial reaction time task

The serial reaction time (SRT) task is a commonly used paradigm to investigate implicit learning. In most studies the settings originally introduced by Nissen and Bullemer are replicated, i.e., subjects respond to a visuo-spatial sequence of stimulus locations by pressing spatially compatible arranged keys. The present experiment was designed to explore to what degree the sequential learning observed under these conditions depends on the use of locational sequences. Under otherwise identical conditions, first the S-R compatibility was reduced by using symbols instead of locations as stimuli, and second, the connectibility, i.e, the ease of connecting successive stimuli into coherent pattern, was varied. Effects on reaction times (RT) in the SRT task and on explicit memory in a generation task were evaluated. The results indicate that the connectibility of the stimuli has no effect at all and that S-R compatibility influences only the general RT level but does not seem to modify the learning process itself. Thus, the data are more consistent with the notion that learning is based primarily on the sequence of responses rather than on the sequence of stimuli. Moreover, a post hoc classification of subjects with regard to the amount of explicit sequence knowledge they have acquired reveals a striking modification of the general result: The RT difference between responses to locations and symbols vanishes in the course of learning for the complete explicit knowledge group. In order to account for this effect, we presume that the response control of these subjects shifts from stimuli to motor programs, so that RTs become increasingly independent of the stimuli used.     

Bayesian inference for psychology,part III: Parameter estimation in nonstandard models

We demonstrate the use of three popular Bayesian software packages that enable researchers to estimate parameters in a broad class of models that are commonly used in psychological research. We focus on WinBUGS, JAGS, and Stan, and show how they can be interfaced from R and MATLAB. We illustrate the use of the packages through two fully worked examples; the examples involve a simple univariate linear regression and fitting a multinomial processing tree model to data from a classic false-memory experiment. We conclude with a comparison of the strengths and weaknesses of the packages. Our example code, data, and this text are available via https://osf.io/ucmaz/.
