Responding in configural discrimination problems depends on density of reinforcement in time

Previous research has shown that conditioned responding in differential skin conductance conditioning increased for reinforced stimuli (CSs+) but remained constant for nonreinforced stimuli (CSs-) due to decreasing reinforcement density. The present two experiments (Experiment 1: Negative patterning; Experiment 2: Positive patterning) were designed to disentangle a possible confound of reinforcement density with stimulus frequency. In order to achieve this, we varied the intertrial interval (18 s, 24 s, or 48 s) and held constant the numbers of CSs+ and of CSs- in each of both discrimination problems. With increasing intertrial intervals, we found higher responding both to CSs+ and to CSs- as well as increased response differentiation. We discuss these results with respect to two mechanisms offered by Wagner's SOP model and conclude that the observed effects are due to variations in density of reinforcement in time.     

Achievement Emotions: A Control-Value Approach

Emotions are ubiquitous in achievement settings. Apart from test anxiety research and attributional studies, psychological research has neglected these emotions. We argue that more research on the functions, origins, and regulation of achievement emotions is needed, addressing both outcome emotions related to success and failure, such as hope, pride, anxiety, shame, and hopelessness, and activity emotions such as the enjoyment and boredom experienced in achievement settings. Using Pekrun’s (2006) control-value theory of achievement emotions as a theoretical framework, we first outline a three-dimensional (object focus × valence × activation) taxonomy of achievement emotions. We then summarize research on the individual and social origins of these emotions, arguing that control appraisals, value appraisals, achievement goals, and related contextual factors are of specific relevance for achievement emotion arousal. Next, the importance of emotions for achievement behavior and performance is addressed. In conclusion, we discuss the regulation and modification of achievement emotions and their relative universality across genders, settings, and cultures.     

Biased Evaluation of Abstracts Depending on Topic and Conclusion: Further Evidence of a Confirmation Bias Within Scientific Psychology

The present paper investigated whether academic psychologists show a tendency to rate the quality and appropriateness of scientific studies more favorably when results and conclusions are consistent with their own prior beliefs (i.e., confirmation bias). In an online experiment, 711 psychologists completed a questionnaire (e.g., about their belief in astrology) and evaluated research that was presented in form of a short abstract in which 40 different behaviors (e.g., alcohol consumption, willingness to share money) have been tried to be predicted. The research to be evaluated varied on three dimensions which were all manipulated between subjects: (1) the predictors of the 40 behaviors (either Big Five or astrological factors), (2) the methodological quality of the study (low, medium, high), and (3) the results and subsequent conclusion of the study (confirmation or disconfirmation of the hypotheses). Factor-analyzed scores of participants’ ratings on 8 scales, resulting in 2 factors termed quality and appropriateness, served as dependent measures. The main result of the study is a two-way interaction: Psychologists tended to evaluate results qualitatively higher when they conformed to their own prior expectations, as in this case, when astrological hypotheses were disconfirmed.     

Transformationsprozesse in der Traumatherapie und die Technik der Prozessdeutung

This article first describes some of the general principles by which according to the latest concepts mental processing is accomplished: a transformative, self-organizational approach driven by emotion and is intersubjective.From this the basic principles for the treatment technique can be derived, which systematically differentiates between content interpretation and process interpretation. Objects of process interpretation are observable transformation events of the traumatic material during consultations, their success and destruction. Process interpretations restore the blocked processing abilities of the patient and in this way also prepare for the possibility to work with content interpretation.     

Teachers’ emotions and emotion management: integrating emotion regulation theory with emotional labor research

While the similarities between emotion regulation (Gross in J Personal Soc Psychol 74:224–237, 1998a) and emotional labor (Hochschild in The managed heart: commercialization of human feeling. University of California Press, Berkeley, 1983) have been theoretically discussed, empirical research on their relation is lacking. We examined the relations between the two constructs as well as their relations with teachers’ discrete emotions in a sample of 189 secondary school teachers. The results showed that reappraisal correlated positively with deep acting, whereas suppression correlated positively with surface acting. The findings further suggest that reappraisal and deep acting are linked to experiencing positive emotions, whereas suppression and surface acting are linked to experiencing negative emotions. However, there also were some differences in how emotion regulation and emotional labor were related to teachers’ discrete emotional experiences. Specifically, reappraisal and deep acting strategies were positively related to enjoyment; in addition, deep acting was negatively related to negative emotions such as anxiety, anger, and frustration. By contrast, suppression and surface acting strategies were positively associated with negative emotions (i.e., suppression with anxiety; surface acting with anxiety, anger, and frustration), and surface acting was negatively associated with the positive emotion enjoyment. Implications for integrating research on teachers’ emotion regulation and emotional labor are discussed.     

Motivational determinants of systematic processing: expectancy moderates effects of desired confidence on processing effort

Extending the motivational assumptions of the heuristic-systematic model (Chaiken, Liberman, & Eagly, 1989), the authors hypothesized that a discrepancy between desired and actual judgmental confidence raises processing effort only if the expectancy that processing will increase confidence is high. In Experiment 1, university students expected to review information for upcoming social judgments. Desired confidence was varied through low versus high task importance. To manipulate expectancy, low versus high perceived processing efficacy was induced via feedback. As predicted, high- (as compared to low-) importance participants expressed greater interest in receiving information and selected more information when perceived efficacy was high, and this effect was mediated via a heightened discrepancy between desired and actual confidence. These effects were not obtained under low perceived efficacy. In Experiment 2, students processed a persuasive message. Only high importance conditions were studied; processing efficacy and argument strength were manipulated. As predicted, high- (but not low-) efficacy participants processed the message systematically, as indicated by a different impact of argument strength and by mediational path analyses. It is argued that the precision of social judgment models would benefit from an explicit consideration of processing- and outcome-related expectancy variables. © 1998 John Wiley & Sons, Ltd.     

Truth in Applicative Theories

We give a survey on truth theories for applicative theories. It comprises Frege structures, universes for Frege structures, and a theory of supervaluation. We present the proof-theoretic results for these theories and show their syntactical expressive power. In particular, we present as a novelty a syntactical interpretation of ID₁ in a applicative truth theory based on supervaluation.
