What you see is what will change: Evaluative conditioning effects depend on a focus on valence

This study investigated whether evaluative conditioning (EC) effects depend on an evaluative focus during the learning phase. An EC effect is a valence change of an originally neutral stimulus (conditioned stimulus or CS) that is due to the former pairing with a positive or negative stimulus (unconditioned stimulus or US). In three experiments, the task focus during the conditioning phase was manipulated. Participants judged CS–US pairings either with respect to their valence or with respect to another stimulus dimension. EC effects on explicit and implicit measures were found when valence was task relevant but not when the non-valent stimulus dimension was task relevant. Two accounts for the valence focus effect are proposed: (1) An additional direct learning of the relation of CS and evaluative responses in the valence focus condition, or (2) a stronger activation of US valence in the valence focus condition compared to the non-valent focus condition.     

An adaptive-learning approach to affect regulation: Strategic influences on evaluative priming

An adaptive cognition approach to evaluative priming is not compatible with the view that the entire process is automatically determined by prime stimulus valence alone. In addition to the evaluative congruity of individual prime–target pairs, an adaptive regulation function should be sensitive to the base rates of positive and negative stimuli as well as to the perceived contingency between prime and target valence. The present study was particularly concerned with pseudocontingent inferences that offer a proxy for the assessment of contingencies from degraded or incomplete stimulus input. As expected, response latencies were shorter for the more prevalent target valence and for evaluatively congruent trials. However, crucially, the congruity effect was eliminated and overridden by pseudocontingencies inferred from the stimulus environment. These strategic inferences were further enhanced when the task called for the evaluation of both prime stimuli and target stimuli.     

Operationalisierte Psychodynamische Diagnostik des Kindes- und Jugendalters

There are only a few studies focusing on the mental structure and its change in children and adolescents with psychiatric disorders. This study aimed at investigating change in the mental structure of children and adolescents over time. At intake 60 inpatients were interviewed with the operationalized psychodynamic diagnostic interview for children and adolescents (OPD-CA). After an average of 27 months 25 patients agreed on participating in the follow-up study. The OPD-CA was conducted again and the Kiddie-Sads present and lifetime version (Kiddie-Sads-PL) as well as parent-based ratings child behaviour checklist (CBCL) and strength and difficulties questionnaire (SDQ) were applied. A consensus rating of the OPD-CA was attained by three researchers well experienced with the use of the OPD-CA. The level of structural integration improved significantly, in particular in the dimensions “control” and “communication skills”. There were no significant changes in the dimension “self-perception/object-perception”. The improvement was also observable in parent-report questionnaires. This study makes a contribution to the idea that changes in the mental structure of children and adolescents can be shown and measured with the OPD-CA.     

After Novelty: The Mundane Practices of Ensuring a Safe and Stable Supply of Bone

New medical technologies to a great extent use material from human bodies as therapeutic tools. Social science studies of such ‘tools’ have tended to focus on technologies associated with novelty and drama. This paper, in contrast, concerns an old, well-entrenched and ostensibly undramatic technology, bone transfers, that has only recently gained public attention. The history of bone transplants is intertwined with a desire for a safe and stable supply of bone. This desire has a number of rarely debated social implications of relevance to transplant medicine in general: the gradual industrialization of procurement; the institutional production of the view of the body as a dividable resource; the emergence of a notion of scarcity; of body parts as waste; of death as a productive moment in which body parts acquire potential exchange value; and of tensions between an ethics of respect for donors and an ethics of efficient procurement. Historical analysis combined with a contemporary phenomenological approach suggests that the ‘newness’ typically associated with usage of human biological material is not related to transplant technologies as a medical discipline as such, but rather to changes in its social organization and features of the everyday experience of living with the transplant technologies.     

Self-compassion,Achievement Goals,and Coping with Academic Failure

Stress-buffering effects of high self-complexity can be explained by two different theoretical models. According to the affective spillover model (Linville, ), a large number of independent self-aspects prevents a generalization of affect after negative but also after positive events. According to the self-regulatory processes model, a large number of self-aspects promotes efficient self-regulation, which is restricted to negative events. Effects of negative and positive events on subsequent changes in depression were investigated in a prospective design. Having a large number of self-aspects was found to attenuate adverse effects of negative events on depression, irrespective of the distinctness of the self-aspects. No buffering effects were observed regarding the relation between positive events and depression. The self-regulatory processes model also predicts that for people with a large number of self-aspects, an increasing number of positive experiences should be generated in response to high levels of stress. This prediction was tested and confirmed in a second part of the study.     

The development of a greeting signal in wild chimpanzees

Adult chimpanzees produce a unique vocal signal, the pant-grunt, when encountering higher-ranking group members. The behaviour is typically directed to a specific receiver and has thus been interpreted as a 'greeting' signal. The alpha male obtains a large share of these calls, followed by the other adult males of the group. In this study, we describe the development of pant-grunting behaviour from the first grunt-like calls of newborn babies to the fully developed pant-grunts in adults. Although babies produce grunts from very early on, they are not directed to others until about 2 months of age. Subsequently, socially directed grunting steadily increases in frequency to peak around 7 months of age, but then decreases again to reach a nadir in older infants and juveniles, while the specificity in use increases. During adolescence, grunt production increases again with grunts given most frequently to socially relevant individuals. As young chimpanzees are closely affiliated to their mothers for the first decade of their lives, we also compared the grunting patterns of mothers and their offspring, which revealed some influences in pant-grunt production. In conclusion, the acquisition of pant-grunting behaviour in chimpanzees is a long-lasting process with distinct developmental phases in which social influences by the mother and other group members are likely to play a role.     

Affective dimensions of odor perception: a comparison between Swiss, British, and Singaporean populations

Do affective responses to odors vary as a function of culture? To address this question, we developed two self-report scales in the United Kingdom (Liverpool: LEOS) and in Singapore (city of Singapore: SEOS), following the same procedure as used in the past to develop the Geneva Emotion and Odor Scale (GEOS: Chrea, Grandjean, Delplanque et al., 2009). The final scales were obtained by a three-step reduction of an initial pool of 480 affective terms, retaining only the most relevant terms to describe odor-related subjective affective states and comprised of six (GEOS) or seven affective dimensions (LEOS and SEOS). These included dimensions that were common to the three cultures (Disgust, Happiness Well-being, Sensuality Desire, and Energy), common to the two European samples (Soothing Peacefulness), and dimensions that were culture specific (Sensory Pleasure in Geneva; Nostalgia and Hunger Thirst in Liverpool; Intellectual Stimulation, Spirituality, and Negative Feelings in Singapore). A comparative approach showed that the dimensional organization of odor-related affective terms in a given culture better explained data variability for that culture than data variability for the other cultures, thus highlighting the importance of culture-specific tools in the investigation of odor-related affect.     

Affect bursts: dynamic patterns of facial expression

Affect bursts consist of spontaneous and short emotional expressions in which facial, vocal, and gestural components are highly synchronized. Although the vocal characteristics have been examined in several recent studies, the facial modality remains largely unexplored. This study investigated the facial correlates of affect bursts that expressed five different emotions: anger, fear, sadness, joy, and relief. Detailed analysis of 59 facial actions with the Facial Action Coding System revealed a reasonable degree of emotion differentiation for individual action units (AUs). However, less convergence was shown for specific AU combinations for a limited number of prototypes. Moreover, expression of facial actions peaked in a cumulative-sequential fashion with significant differences in their sequential appearance between emotions. When testing for the classification of facial expressions within a dimensional approach, facial actions differed significantly as a function of the valence and arousal level of the five emotions, thereby allowing further distinction between joy and relief. The findings cast doubt on the existence of fixed patterns of facial responses for each emotion, resulting in unique facial prototypes. Rather, the results suggest that each emotion can be portrayed by several different expressions that share multiple facial actions.     

In the eye of the beholder? Universality and cultural specificity in the expression and perception of emotion

Do members of different cultures express (or “encode”) emotions in the same fashion? How well can members of distinct cultures recognize (or “decode”) each other's emotion expressions? The question of cultural universality versus specificity in emotional expression has been a hot topic of debate for more than half a century, but, despite a sizeable amount of empirical research produced to date, no convincing answers have emerged. We suggest that this unsatisfactory state of affairs is due largely to a lack of concern with the precise mechanisms involved in emotion expression and perception, and propose to use a modified Brunswikian lens model as an appropriate framework for research in this area. On this basis we provide a comprehensive review of the existing literature and point to research paradigms that are likely to provide the evidence required to resolve the debate on universality vs. cultural specificity of emotional expression. Applying this fresh perspective, our analysis reveals that, given the paucity of pertinent data, no firm conclusions can be drawn on actual expression (encoding) patterns across cultures (although there appear to be more similarities than differences), but that there is compelling evidence for intercultural continuity in decoding, or recognition, ability. We also note a growing body of research on the notion of ingroup advantage due to expression “dialects,” above and beyond the general encoding or decoding patterns. We furthermore suggest that these empirical patterns could be explained by both universality in the underlying mechanisms and cultural specificity in the input to, and the regulation of, these expression and perception mechanisms. Overall, more evidence is needed, both to further elucidate these mechanisms and to inventory the patterns of cultural effects. We strongly recommend using more solid conceptual and theoretical perspectives, as well as more ecologically valid approaches, in designing future studies in emotion expression and perception research.
