Reactions to success and failure in public and in private conditions

It was shown that the reaction to success and failure differs when it is communicated publicly or privately and when the reaction to success and failure is measured publicly or privately. Participants took an intelligence test and received fictitious results which were positively or negatively discrepant from the average. The dependent variable was the evaluation of the intelligence test. It was found that when the subject's evaluation of the test was private, the test was evaluated more positively under public than under private success. However, it was evaluated more negatively under public than under private failure. Under public success feedback the test was evaluated more positively under private than under public evaluation, whereas under public failure feedback the effect was reversed. The results are interpreted in terms of a self-presentation model and were discussed in the context of earlier research within the field of interpersonal relations.     

Psychobiology of altered states of consciousness

The article reviews the current knowledge regarding altered states of consciousness (ASC) (a) occurring spontaneously, (b) evoked by physical and physiological stimulation, (c) induced by psychological means, and (d) caused by diseases. The emphasis is laid on psychological and neurobiological approaches. The phenomenological analysis of the multiple ASC resulted in 4 dimensions by which they can be characterized: activation, awareness span, self-awareness, and sensory dynamics. The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes. Besides these severe alterations, environmental stimuli, mental practices, and techniques of self-control can also temporarily alter brain functioning and conscious experience.     

The facial pattern of disgust, appetence, excited joy and relaxed joy: an improved facial EMG study

The purpose of the study was to investigate the facial muscle pattern of disgust in comparison to appetence and joy, using an improved facial EMG method. We analyzed the activity of nine facial muscles in forty healthy subjects. The subject group was randomly divided into two groups (oversaturated vs. hungry) of ten women and ten men each. Four different emotions (disgust, appetence, excited-joy and relaxed-joy) were induced by showing pictures from the IAPS. Pre-visible facial muscle activity was measured with a new facial EMG. A Visual Analog Scale (VAS) was established. Disgust is represented by a specific facial muscle pattern involving M.corrugator and M.orbicularis oculi, clearly distinguishing it from the facial patterns of appetence and joy. The intensity of disgust is stronger in a state of hunger than under oversaturation and is altogether stronger in females than in males. Our findings indicate the possibility to explore the entire emotion system successfully through a state-of-the-art psychophysiological method like our EMG device.     

Visual search for singleton feature targets within and across feature dimensions

Three experiments investigated visual search for singleton feature targets. The critical dimension on which the target differed from the nontargets was either known in advance or unknown—that is, the critical difference varied eitherwithin a dimension oracross dimensions. Previous work (Treisman, 1988) had shown that, while the search reaction time (RT) functions were flat in both conditions, there was an intercept cost for the cross-dimension condition. Experiment 1 examined whether this cost would disappear when responses could be based on the detection ofany (target—nontarget) difference in the display (by requiring a “heterogeneity/homogeneity” decision). The cost remained. This argues that pop-out requires (or involves) knowledge of the particular dimension in which an odd-one-out target differs from the nontargets; furthermore, that knowledge is acquired through the elimination of dimensions not containing a target. In Experiment 2, the subjects had to eliminate (or ignore) one potential source of difference in order to give a positive response (displays could contain a “noncritical” difference requiring a negative response). The result was a comparatively large cost in the within-dimension (positive) condition. This can be taken to indicate that popout as such does not make available information as to the particular feature value in which the target differs from the nontargets. Experiment 3 examined whether search priorities can be biased in accordance with advance knowledge of the likely source of difference. The subjects were found to have a high degree of top-down control over what particular dimension to assign priority of checking to. The implication of the results for models of visual search and selection are discussed.     

Transfer of training from introductory computer courses is highly specific ... and negative!

Two groups of students in an introductory computer course learned either BASIC programming or the use of applications software. Students in the programming group learned to use a simple line editor to edit their programs, whereas students in the applications group learned to use a sophisticated cursor-oriented word processor. When both groups were tested on a simulated line-oriented text editor, there were no differences in overall performance, although both groups performed more poorly than did a group of introductory psychology students with no previous computer background. Different error patterns in the two groups for different commands suggest specific kinds of negative transfer due to their prior experiences. These results call into question the assumption that training students in one computer skill facilitates transfer to other situations.     

Individual and social network predictors of the short‐term stability of bullying victimization in the United Kingdom and Germany

Background. There is still relatively little research on the social context within which bullying develops and remains stable. Aim. This study examined the short‐term stability of bullying victimization among primary school students in the United Kingdom and Germany (mean age, 8.9 years) and the individual and social network factors that contributed to remaining a victim of bullying. Sample. The sample consisted of 454 children (247 males and 207 females). Methods. Participants completed questionnaires on bullying victimization at three assessment points over a 9‐week period. Other measures consisted of self‐reported demographic, peer, and family relationship characteristics. Social network indices of density, reciprocity, and hierarchy were constructed using friendship and peer acceptance nominations. Results. Relative risk analyses indicated a six‐fold increased risk of remaining a victim at consequent follow‐ups, compared to a child not victimized at baseline becoming a victim over the follow‐up period. Individual characteristics explained substantially more variance in the stability of bullying victimization than class‐level factors. Hierarchical logistic regression analyses revealed that being victimized by siblings and being rejected by peers predicted remaining a victim over a 9‐week period. Conclusions. Bullying victimization among primary school students proved moderately stable over a 9‐week period. Individual characteristics were more influential in predicting the stable victim role than class‐level factors. Our findings have implications for the identification of stable victims in primary school and early preventative bullying programs.     

Awareness is awareness is awareness? Decomposing different aspects of awareness and their role in operant learning of pain sensitivity

Regarding awareness as a consistent concept has contributed to the controversy about implicit learning. The present study emphasized the importance of distinguishing aspects of awareness in order to determine whether learning is implicit. By decomposing awareness into awareness of contingencies, of the procedure being a learning task, and of the reinforcing stimuli, it was demonstrated that implicit operant learning modulated pain sensitivity. All of these aspects of awareness were demonstrated to not be necessary for learning. Additionally, discrimination of contingencies was not necessary on different levels of processing as demonstrated by a verbal and a behavioral method. It was demonstrated that explicit cognitive processes about one's own behavior, impaired learning, even though these cognitions were not immediately related to the learning process. The results of this study are of special interest in the context of pain, since implicit operant learning can explain the gradual development of hypersensitivity in chronic pain.
