Reinstatement of extinguished conditioned responses and negative stimulus valence as a pathway to return of fear in humans

The present study investigated reinstatement of conditioned responses in humans by using a differential Pavlovian conditioning procedure. Evidence for reinstatement was established in a direct (fear rating) and in an indirect measure (secondary reaction time task) of conditioning. Moreover, the amount of reinstatement in the secondary reaction time task was significantly correlated with the difference in valence between the conditioned stimulus (CS)+ and the CS-after extinction. These data provide clear evidence for reinstatement and for the role of negative stimulus valence in the return of conditioned responding after extinction.     

Sequential and simultaneous feature positive discriminations: occasion setting and configural learning in human Pavlovian conditioning

Using a conditioned suppression preparation, the authors investigated sequential (X --> A+/A-) versus simultaneous (XA+/A-) feature positive (FP) discrimination learning in humans. The sequential discrimination was expected to be resolved by means of a Feature X Modulated Target A-US association and the simultaneous discrimination by a feature X-US association. After sequential FP training, extinction of Feature X did not affect discriminative X --> A/A responding (Experiment 1), and X transferred its modulatory ability only to new targets, B, that had also been modulated (Experiment 2). This suggests that the sequential FP discrimination indeed resulted in occasion setting. Unlike expected, Feature X Extinction did not affect discriminative XA/A responding after simultaneous FP training (Experiment 3), while at the same time Feature X did show the predicted nonselective transfer to new targets, B (Experiment 4). J. M. Pearce's (1987) configural learning theory can account for most but not all findings of Experiments 3 and 4.     

Expectancy-learning and evaluative learning in human classical conditioning: affective priming as an indirect and unobtrusive measure of conditioned stimulus valence

It has been argued that in classical conditioning two processes might be operative. First, one may learn that the conditioned stimulus (CS+) is a valid predictor for the occurrence of the biologically negative or positive event (US; expectancy-learning). Second, one may learn to perceive the conditioned stimulus itself as a negative or positive stimulus, depending on the valence of the event it has been associated with (evaluative learning). Until the present, however, both forms of learning have been investigated using rather different conditioning procedures. Using a differential aversive conditioning preparation with pictures of human faces as CSs and an electrocutaneous stimulus as US, we were able to demonstrate that both forms of learning can co-occur. Moreover, the extent of evaluative learning in this aversive conditioning procedure did not significantly differ from the amount of evaluative learning in an evaluative conditioning procedure with positive and negative adjectives as USs, which was administered to the same participants. In the present study evaluative learning was not only indexed by direct evaluative ratings, but we introduced affective priming as an indirect and unobtrusive, reaction time based measure of stimulus valence. Finally, imagery instructions during acquisition did not facilitate expectancy-learning nor evaluative learning.     

Internal consistency reliability and construct validity of the Dutch translation of the Francis Scale of Attitude toward Christianity among adolescents

A sample of 1,021 young people attending Years 7, 8, 9, 10, and 11 at Catholic secondary schools within the state-maintained sector completed the Dutch translation of the Francis Scale of Attitude toward Christianity. The data support its reliability and validity and commend it for further use in studies conducted among young people in The Netherlands.     

Prior probability modulates anticipatory activity in category-specific areas

Bayesian models are currently a dominant framework for describing human information processing. However, it is not clear yet how major tenets of this framework can be translated to brain processes. In this study, we addressed the neural underpinning of prior probability and its effect on anticipatory activity in category-specific areas. Before fMRI scanning, participants were trained in two behavioral sessions to learn the prior probability and correct order of visual events within a sequence. The events of each sequence included two different presentations of a geometric shape and one picture of either a house or a face, which appeared with either a high or a low likelihood. Each sequence was preceded by a cue that gave participants probabilistic information about which items to expect next. This allowed examining cue-related anticipatory modulation of activity as a function of prior probability in category-specific areas (fusiform face area and parahippocampal place area). Our findings show that activity in the fusiform face area was higher when faces had a higher prior probability. The finding of a difference between levels of expectations is consistent with graded, probabilistically modulated activity, but the data do not rule out the alternative explanation of a categorical neural response. Importantly, these differences were only visible during anticipation, and vanished at the time of stimulus presentation, calling for a functional distinction when considering the effects of prior probability. Finally, there were no anticipatory effects for houses in the parahippocampal place area, suggesting sensitivity to stimulus material when looking at effects of prediction.     

Impact of Genomic Counseling on Informed Decision-Making among ostensibly Healthy Individuals Seeking Personal Genome Sequencing: the HealthSeq Project

Personal genome sequencing is increasingly utilized by healthy individuals for predispositional screening and other applications. However, little is known about the impact of ‘genomic counseling’ on informed decision-making in this context. Our primary aim was to compare measures of participants’ informed decision-making before and after genomic counseling in the HealthSeq project, a longitudinal cohort study of individuals receiving personal results from whole genome sequencing (WGS). Our secondary aims were to assess the impact of the counseling on WGS knowledge and concerns, and to explore participants’ satisfaction with the counseling. Questionnaires were administered to participants (n = 35) before and after their pre-test genomic counseling appointment. Informed decision-making was measured using the Decisional Conflict Scale (DCS) and the Satisfaction with Decision Scale (SDS). DCS scores decreased after genomic counseling (mean: 11.34 before vs. 5.94 after; z = ?4.34, p < 0.001, r = 0.52), and SDS scores increased (mean: 27.91 vs. 29.06 respectively; z = 2.91, p = 0.004, r = 0.35). Satisfaction with counseling was high (mean (SD) = 26.91 (2.68), on a scale where 6 = low and 30 = high satisfaction). HealthSeq participants felt that their decision regarding receiving personal results from WGS was more informed after genomic counseling. Further research comparing the impact of different genomic counseling models is needed.     

Predictors of children's entertainment television viewing: Why are they tuning in?

Three hundred and twenty six 3- and 5-year-olds (N = 160 3-year-olds) participated in a longitudinal study of the sociological and ecological predictors of children's general audience and child entertainment viewing. Viewing was assessed through five weekly diaries for each child, completed by families over a two-year period. Concurrent analyses of program availability, family demographics/attributes, and child characteristics indicated that children who were frequent viewers of entertainment programs had parents who had limited education, access to cable, and incorporated television into their activities. Although parental regulation and encouragement played a role in children's viewing experiences, particularly at 5 and 7 years of age, the strongest long-term predictors on children's entertainment viewing were parents' education, family size, and the age and sex of the child. Parents need to become more aware of their role in shaping their children's viewing habits. Responsibility for improving children's television viewing experiences, however, should not rely solely with parents but must be shared by educators, broadcasters, and legislators.     

Imaginal Dialogues in the Self:Theory and Method

ABSTRACT The story a person tells about his or her life is viewed as a polyphonic novel. This metaphor implies that the self is multivoiced; that is, there is no single "I" as an agent of self-organization but several, relatively independent "I" positions that complement and contradict each other in dialogical relationships. From this perspective the role ofimaginal figures in the organization of the self is analyzed. A theory and method are presented allowing us to study both the content and the organization of multivoiced self-narratives. The method is illustrated with two idiographic studies, where people tell their life story not only from the perspective of the familiar "I" but also from the perspective of an imaginal figure with whom they have had a long-lasting relationship. Finally, it is argued that the metaphor of a polyphonic novel is particularly useful because it allows us to decentralize the Western concept of the self.     

Life Tasks and Daily Life Experience

ABSTRACT This article explores the assumption that the goals on which an individual works structure the experience of daily life. One set of important goals are those consensual tasks that reflect the age-graded expectations of a living environment (e.g., the task of being on one's own at college). Whereas most members of a common age group share these consensual life tasks, individuals in a group differ in the relative importance they place on different tasks and in their appraisals of them. In the present study of 54 women living in a college sorority, the importance of a life task was associated with increased relevance of the task to daily life events, as revealed in experience sampling. The women were more emotionally involved in events that they saw as highly relevant to their life tasks than in less relevant events and, for each person, positive affect and emotional involvement in task-relevant events were related to her initial life task appraisals.     

The personal meaning of symbols: A method of investigation

In light of the inherent significance of symbols and their nevertheless manifold variety of meanings, we present a method for investigation. In the theory behind this method, the person is viewed as an organized process of self-reflection, always oriented from a particular point in time and space toward the past, present, and future. As this orientation varies, different valuations emerge, with avaluation being a unit of meaning seen by the person as particularly relevant in his or her own life. A distinction is made between symbolic valuations, which usually have a pictorial character (for example, I am impressed by the roots of a tree), and ordinary valuations, which typically have a conceptual character (for example, I have a strong bond with my family). These types of experiences are combined and organized in a system of valuations, from where the symbol receives its personal meaning. We present a method of self-investigation for studying the interrelation between the valuation of symbols and the valuation of daily life, the affective properties of these valuations, their motivational implications, and their long-term development. We illustrate the proposed methodology with the case study of a woman who incorporated the tree as a symbol of purification into her valuation system and show how this allowed her to reintegrate certain negative experiences out of her past in her actual self.The authors thank Wim van Gilst for writing the computer program, Roos Bos for placing all the data of the case study at their disposal, and Lee Ann Weeks for her detailed editorial comments.
