Wahrheitsähnlichkeit als Regulativ der Intentionalität?

Is there still any importance of Husserl's Phenomenology for contemporary forms of philosophy of science? A comparison between Phenomenology and a prominent form of such modern philosophy of science, the so-called Critical Rationalism of Karl Popper, may help to answer this question. Therefore, the different levels of argumentation have to be worked out to make the respective arguments applicable to one another. We are arguing for the following thesis: the strategy of corroboration in Critical Rationalism can be justified by means of the phenomenological conception of intentioality of consciousness. A typical example may illustrate how Popper's conception of taking the degree of corroboration as an indicator of the degree of verisimilitude can find its deeper foundation in Husserl's genetic interpretation of ordinary kinds of experience.     

Witnessed inclusion improves identification of Duchenne and non-Duchenne smiles

Social exclusion threatens a person's need to belong and prompts them to behave in ways that often facilitate reaffiliation. For adults, direct exclusion increases attention to social information and facial cues, including an enhanced identification of Duchenne and non-Duchenne smiles. Furthermore, inclusion can buffer or mitigate the effects of exclusion. This study investigated children's (N = 44) and adults’ (N = 52) sensitivity to perceptual changes in smiles following witnessed inclusion and exclusion and inclusion's mitigating and buffering effects on perceptual abilities. Contrary to our predictions, participants in our study demonstrated improved accuracy after witnessing inclusion, rather than exclusion, and showed no buffering or mitigating effects of inclusion. This contradiction with previous findings points to a further need to explore the effects of witnessed versus direct inclusion and exclusion, especially if witnessed inclusion and exclusion have the ability to impact perception and shape our behavior.     

Promoting us or preventing them: regulatory focus and manifestations of intergroup bias

Four studies examined whether situational and individual differences in individuals' regulatory focus influence how intergroup bias is expressed emotionally and behaviorally. Consistent with past findings on promotion focus, these studies found evidence that participants' promotion focus, whether measured or manipulated, was related to how extensively they demonstrated bias toward their ingroup in terms of cheerfulness- and dejection-related emotions and approach-related behaviors. Consistent with past findings on prevention focus, these studies also revealed that participants' prevention focus was related to how extensively they showed bias against an outgroup in terms of quiescence- and agitation-related emotions and avoidance-related behaviors. The implications for the self-regulatory functions of intergroup bias are discussed.     

Training student teachers to reposition infants frequently

We evaluated the effects of an intervention designed to increase the variety of positions experienced by infants in a child-care setting. Six student teachers were trained, using a multicomponent intervention, to reposition infants according to a chart. The intervention was successful in increasing the mean percentage of correct position changes made by all 6 student teachers, and performance gains by 3 student teachers persisted when supervisor feedback was briefly removed.     

Strength and safety in numbers: considering the social implications of regulatory focus

The present article examines how individual and situational differences in individuals' regulatory focus on nurturance and gain (promotion) and on security and safety (prevention) may have significant, and distinct, social and interpersonal implications. We first review recent research examining how significant others affect goal pursuit and how individual differences in regulatory focus may moderate the various behavioral, evaluative, and experiential manifestations of social identification. We then consider how regulatory focus moderates the way in which people "size up" their social world in terms of the efficiency in which they identify and appraise motivationally relevant aspects of their social environment. Finally, we explore how regulatory focus moderates people's deliberate and automatic reactions to the beliefs, expectations, behavior, and emotions of other individuals and social groups.     

On shame and the perceived credibility of sexual assault allegations

Despite the high incidence of sexual assault, doubt about allegations is common. Previous research suggests that victims expressing positive or no emotion are perceived as less credible than those expressing negative emotions. However, little is known about which specific negative emotional expressions contribute to credibility in this context. In two studies (N = 623), participants read a date rape vignette. The alleged victim's statement was paired with a picture of a female person expressing either shame, sadness, or no emotion. Participants rated the credibility of her account and completed a measure of rape myth acceptance. Controlling for rape myth acceptance, allegations were perceived as more credible when accompanied by an expression of shame versus sadness (a negative, low arousal control condition). It is critical to be aware of the shame-credibility bias in this context to intervene and support those who have experienced sexual assault.     

Peer relationships and depressive symptomatology in boys at puberty

The physical changes of puberty coincide with an increase in the salience of peer relationships and a growing risk for depression and other forms of psychopathology. Previously, we reported that pubertal tempo, defined as a child's rate of intraindividual change in pubertal status (measured using parent-reported Tanner stages; Marshall & Tanner, 1970), was associated with changes in boys'--but not girls'--depressive symptoms over and above effects explained by pubertal timing (Mendle, Harden, Brooks-Gunn, & Graber, 2010). The present study extends this previous research by examining changes in the quality of peer relationships in the association between individual differences in pubertal development and change in boys' depressive symptoms. Boys (N = 128, M = 9.61 years, SD = 0.70, at Time 1) were recruited from public schools and assessed annually for 4 years. Results from latent growth curve models indicated that earlier pubertal timing and more rapid pubertal tempo were associated with greater decrements in the quality of boys' peer relationships. After accounting for the association between change in peer relationships and depressive symptoms, the direct effects of pubertal timing and tempo on depressive symptoms were no longer significant. These results highlight a multifaceted approach to studying puberty and emphasize how social mechanisms may intersect with biological risk to produce psychological distress.     

Genetically influenced change in sensation seeking drives the rise of delinquent behavior during adolescence

Sensation seeking is associated with an increased propensity for delinquency, and emerging research on personality change suggests that mean levels of sensation seeking increase substantially from childhood to adolescence. The current study tested whether individual differences in the rate of change of sensation seeking predicted within-person change in delinquent behavior and whether genetically influenced differences in rate of personality change accounted for this association. Sensation seeking and delinquent behavior were assessed biennially between ages 10-11 and 16-17 in a nationally representative sample of 7675 youths from the National Longitudinal Study of Youth: Children and Young Adults (CNLSY). Analyses using latent growth curve modeling found that within-person change in sensation seeking was significantly and positively correlated with within-person change in delinquency from childhood to adolescence. Furthermore, behavioral genetic analyses of a subset of 2562 sibling pairs indicated that there were substantial genetic influences on both initial levels of sensation seeking and change in sensation seeking during early adolescence, with over 80% of individual differences in change due to genetic factors. Finally, these genetically driven increases in sensation seeking were most important for predicting increases in delinquency, whereas environmental paths between sensation seeking and delinquency were not significant. These results suggest that developmental changes in delinquent behaviors during adolescence are driven by a genetically governed process of personality change.
