Association Learning with Own‐ and Other‐race Faces in three‐ and six‐month old infants – A longitudinal study

This longitudinal study assessed 133 Caucasian German infants at 3 and 6 months of age to investigate the influence of own‐race and other‐race faces as visual stimuli on association learning in the visual expectation paradigm (VExP). The study is related to the findings on the other‐race‐effect (ORE) which is said to emerge at 6 months of age. Caucasian faces were used as stimuli of a familiar ethnic category, whereas African faces were used as stimuli of an unfamiliar ethnic category. There was no significant difference between the two stimulus classes in infants' reaction time (RT) to stimulus shifts at 3 months. At 6 months of age, infants' RT decreased significantly in the Caucasian faces condition but not in the African faces condition. These results indicate that the processing of other‐race versus own‐race faces by the age of 6 months, which is also the relevant age for the onset of the ORE, has an important influence on the performance on the VExP.

Infant Contingency Learning in Different Cultural Contexts

Three‐month‐old Cameroonian Nso farmer and German middle‐class infants were compared regarding learning and retention in a computerized mobile task. Infants achieving a preset learning criterion during reinforcement were tested for immediate and long‐term retention measured in terms of an increased response rate after reinforcement and after a 24‐h delay compared with baseline. It was hypothesized that infants from both cultural communities would acquire the contingency between own motion and mobile movement, as they similarly experience contingent responses in social interactions. Nso infants were assumed to show a higher learning rate related to their advanced gross motor development, whereas German infants were expected to show a higher baseline because of culture‐typical motor handling promoting a high level of activity (i.e. lying supine). Results showed immediate and long‐term retention in infants from both cultural contexts, as well as a higher baseline for German infants. Although the learning rate was higher for Cameroonian infants, logistic regression revealed that learning was not related to gross motor development but depended on the level of baseline response. Thus, contingency learning was shown in different cultural environments, and the level of baseline activity coined by culture‐specific motor handling turned out to influence learning within the mobile task.

Body image trends among Icelandic adolescents: a cross-sectional national study from 1997 to 2010

The aim of this study was to evaluate trends in body image among Icelandic adolescents from 1997 to 2010. Data from five cross-sectional surveys conducted among national samples of 9th and 10th graders in Iceland using five time points (1997, 2000, 2006, 2009, and 2010) were compared to examine changes in body image. In total, 32,397 adolescents participated in the study. Body image among 14-15-year-old adolescents in Iceland improved significantly over the 13-year period. Girls reported more negative body image than boys at all time points. However, the positive change in body image from 1997 to 2010 was more pronounced for girls than boys, resulting in a narrower gap between the genders. The current results are encouraging and indicate that in an age of increased overweight and obesity, the body image of Icelandic adolescents is becoming more positive.     

Interaction effects of perceived gaze direction and dynamic facial expression: Evidence for appraisal theories of emotion

Appraisal theorists suggest that the face expresses cognitive processes involved both in the orienting of attention (primarily gaze direction) and in the evaluation of emotion-eliciting events. Contrary to the assumption of direct emotion recognition by basic emotions theorists, this implies an interaction effect between “perceived gaze direction” and “perceived facial expression” in inferring emotion from the face. These two theoretical perspectives were comparatively tested by requesting participants to decode dynamic synthetic facial expressions of emotion presented with either an averted or a direct gaze. Confirming the interaction predicted by appraisal theories, the perceived specificity and intensity of fear and anger depended on gaze direction (direct gaze for anger and averted gaze for fear).     

Health performance of individuals within the Campbell paradigm

In this paper, we developed a comprehensive health performance measure that formally links individual health attitudes with the likelihood of engaging in a wide variety of health‐related behaviours from various domains such as sustenance, hygiene, and physical exercise. Within what Kaiser, Byrka, and Hartig (2010) call the Campbell paradigm, we equated general health attitude with what a person does to retain or promote his or her health. Thus, health behaviours, on one hand, were expected to form a homogeneous, transitively ordered class of behaviours. On the other hand, the very behavioural class was in turn thought to be the basis from which an individual's health attitude could be directly assessed. A sample of 391 adults provided us with survey data containing different sets of health behaviours as well as variables and personality measures that had been corroborated as health‐behaviour relevant in previous research. We found that self‐reports of 50 behaviours and expressions of appreciation for 20 of these behaviours from various domains formed a transitively ordered class of activities. In contrast to the conventional view in health psychology, in which attitudes are regarded as a psychological cause behind individual behaviour, and in contrast to conventional findings in health psychology, where behaviours appear to fall into numerous sets of more or less distinct domains of health‐enhancing activities (e.g., exercising or avoiding risks), our findings speak of the psychological and formal unity of health behaviour. Inevitably, attitude measures grounded in the Campbell paradigm gauge individual attitudes, and just as much, they measure the health performance of individuals.     

Inhibiting the mentalizing capacities

This paper describes a phobic patient who inhibited her capacity to mentalize defensively in situations when emotionally overwhelmed. When provoked by anxiety, she used the ‘silencing-method’, not reflecting on her internal world or her relationships. In order to avoid painful thinking, she stopped mentalizing and used practical or physical activities as a psychic retreat from an unpleasant reality. In psychoanalysis, she developed a growing tolerance to conceiving her own mental states However, even after several years of analysis, inhibiting her mentalizing capacities remained her defensive strategy. This paper suggests that phobia could be understood as an intolerance of conceiving mental states, preventing integration of psychic trauma. Improvement of the mentalizing capacities through psychoanalysis makes phobic symptoms fade.     

Mixed emotions: Holistic and analytic perception of facial expressions

In the face literature, it is debated whether the identification of facial expressions requires holistic (i.e., whole face) or analytic (i.e., parts-based) information. In this study, happy and angry composite expressions were created in which the top and bottom face halves formed either an incongruent (e.g., angry top + happy bottom) or congruent composite expression (e.g., happy top + happy bottom). Participants reported the expression in the target top or bottom half of the face. In Experiment 1, the target half in the incongruent condition was identified less accurately and more slowly relative to the baseline isolated expression or neutral face conditions. In contrast, no differences were found between congruent and the baseline conditions. In Experiment 2, the effects of exposure duration were tested by presenting faces for 20, 60, 100 and 120 ms. Interference effects for the incongruent faces appeared at the earliest 20 ms interval and persisted for the 60, 100 and 120 ms intervals. In contrast, no differences were found between the congruent and baseline face conditions at any exposure interval. In Experiment 3, it was found that spatial alignment impaired the recognition of incongruent expressions, but had no effect on congruent expressions. These results are discussed in terms of holistic and analytic processing of facial expressions.     

Expectations about the future and the emotional consequences of perceiving prejudice

Three studies tested the hypothesis that possessing a pessimistic outlook on life moderates the effects of perceiving sexism on emotions and self-esteem. Across all studies, a pessimistic outlook on life (either dispositionally held or experimentally induced) served as a source of emotional vulnerability among women (Studies 1-3) and men (Study 1) faced with evidence of sexism directed against their gender group. Study 3 demonstrated that one's outlook on life influences emotional adjustment to prejudice through the cognitive appraisal process. Relative to optimists, pessimists appraised sexism as more stressful and believed they possessed fewer resources for coping with it. This research emphasizes the importance of examining sources of vulnerability and resilience in understanding emotional responses to prejudice.     

Consensus conference on environmental values in radiation protection: a report on building consensus among experts

During the fall of 2001 (October 22–25), The Norwegian Radiation Protection Authority (NRPA) and the Agricultural University of Norway arranged a consensus conference on the protection of the environment against ionising radiation. The motive for the conference was the need to study the ethical and philosophical basis for protection of nature in its own right. The conference was funded by Nordic Nuclear Safety Research (NKS), in cooperation with the International Union of Radioecology (IUR). The National Committee for Research Ethics in Science and Technology (NENT) was hired as facilitators for the consensus process. This paper will give a brief outline of the aims and method of the conference, distinguishing these from other kinds of consensus conferences. The paper ends with some general reflections on the appropriateness of seeking consensus on ethics-related issues among experts.     

Gaze behavior in analytical and holistic face processing

We conducted two experiments examining children's and adults' gaze behavior when processing faces analytically (focusing on a single feature) or holistically (comparing the overall similarity of the faces). Children 6-8 and 9-10 years of age and adults were instructed to assign schematically drawn faces in Experiment 1 and photos of real faces in Experiment 2 to two categories. The categories were constructed so as to allow either an analytical or holistic categorization of the faces. During all trials, gaze behavior was recorded from stimulus onset until reaction. The location and duration of the fixations used were analyzed. Whereas the holistic processors fixated the whole area of the eyes and nose most and longest independently of age, analytical processors showed a more feature-specific gaze behavior, focusing their fixations upon the particular feature used for subsequent processing. Thus, differences in analytical and holistic face processing can be detected early in gaze behavior-that is, at the visual encoding stage.
