Trial-by-trial effects in the affective priming paradigm

In this paper, we yield evidence for the dependence of affective priming on the congruency of the previous trial. Affective priming refers to the finding that valence categorizations of targets are facilitated when the preceding prime is of the same valence. In two experiments, affective priming was diminished after incongruent trials (i.e., prime and target were of different valence), whereas, significant affective priming was observed after congruent trials (i.e., prime and target were of same valence). We compare this pattern to the known sequential dependencies in Stroop- and Eriksen-type tasks. Furthermore, our results can help to improve the statistical power of studies in which the affective priming task is used as a measure for automatic evaluations of attitude-objects.     

Who is watching Big Brother? TV consumption predicted by masked affective priming

In the present study (N=37), we assessed attitudes towards a telecast (Big Brother) with indirect (masked affective priming) and direct (semantic differentials) methods. Additionally, participants recorded their TV viewing behaviour for a period of 7 days. Implicit positivity of the telecast (assessed by the affective priming task), explicit positivity (semantic differentials), and minutes per week spent viewing the TV show were all positively correlated. Viewers of the telecast show a positive priming effect for the label of the telecast (thereby indicating a positive implicit attitude towards the show). Implications for the research and the theoretical debate on implicit attitudes are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Determinants of a Negotiator's Initial Opening Offer

Although the initial offer is a crucial aspect in the process of most negotiations, there is still a complete lack of empirical evidence on what underpins initial offer decisions. For this reason, the effects of different reference points on the negotiator's initial offer were examined in this study. Results from a sample of 596 managers indicate that knowledge of the opponent's best available alternative, or (Best Alternative To a Negotiated Agreement BATNA), is by far the strongest determinant. Criteria of fairness, as reflected in an estimated market price, are also important. However, awareness of the dependency of the other party has no direct effect on the initial offer. Apparently, negotiators define the negotiation game as the management of interdependency in an extremely egocentric way and base their opening offers largely on cues regarding the power structure within the dyad.     

Reducing chronic anxiety by making the threatening event predictable: An experimental approach

Panic disorder is characterized by both specific, phased fear and generalized, chronic anxiety. Standard extinction procedures are efficient in reducing specific fear. However, methods based on human conditioning research - that are capable of reducing chronic anxiety have not yet been thoroughly investigated. This study evaluates a new way of reducing chronic anxiety by signaling aversive events (or by making them more predictable). Using an experimental approach with healthy participants, specific fear and chronic anxiety were operationalized in a within-subjects fear-potentiated startle paradigm by, respectively, conditioning to a cue by presenting predictable shocks and conditioning to a context induced by unpredictable shocks. The results clearly demonstrate that context conditioning is reduced when a discrete cue is added that predicts the onset of the aversive event. The data suggest that making unpredictable events, such as for example panic attacks, predictable, may reduce the generalized and sustained anxiety that often complicates exposure treatment.     

Emotional reactivity and self-regulation in relation to personality disorders

Associations of both reactive and regulative temperamental features with personality disorders (PDs) are investigated in a sample of 162 normal controls and 89 psychiatric inpatients. Reactive and regulative temperamental features were assessed by means of the BIS/BAS Scales and the Attentional Control Scale. Dimensional PD scores were obtained by using the ADP-IV. All PDs were characterized by low levels of effortful control, cluster C PDs by high BIS and cluster B PDs by high BAS. For several PDs, BIS and effortful control interacted: BIS was only related to severe PD pathology if effortful control was low. Clinical implications of these findings are discussed.     

Which Societies Provide a Strong Religious Socialization Context? Explanations Beyond the Effects of National Religiosity

Religious socialization occurs within the immediate family as well as in the broader social context. Previous research has shown that parents’ religiosity matters less for the transmission of religious beliefs in devout than in secular nations, implying smaller costs of religious socialization. In this article we test which other societal factors affect the transmission of religious beliefs: anti‐religious policies in formerly socialist countries, economic development, and income inequality. Our results indicate that societies with high levels of income inequality seem to provide the most favorable context for religious socialization. Individuals develop strong religious beliefs even if they only received little religious socialization within the family. Formerly socialist nations increased socialization costs through the overall suppression of religious practice. Economic development has no impact on socialization effects, suggesting that inequality is a more important driver of religious change than previously thought.     

The detection of semantic illusions: Task-specific effects for similarity and position of distorted terms

The effect of task demands on the detection of semantic illusions was investigated. In Exp. 1, subjects were given a detection task with different instructions for accuracy. Less illusions occurred under instructions that stressed accuracy, indicating strategic control of detection rates. In Exp. 2, sentences with dissimilar distorted terms resulted in shorter latencies than sentences with similar distorted terms in a detection task, but in longer response times in a question-answering task. In Exp. 3, the similarity effect was found to vary with the position of the distorted term in combination with task demands. In a verification task, the similarity effect did not differ for the beginning or the end of sentences. In a question-answering task, a significant similarity effect was observed only for distorted terms at the beginning of sentences. We argue that the results indicate minimal depth of semantic processing with respect to different task requirements. Implications for different theoretical accounts of semantic illusions are discussed.     

Heading backward: Perceived direction of movement in contracting and expanding optical flow fields

Two goals were pursued in an investigation of possible visual sources for directionality judgments of ego-motion. First, J. J. Gibson’s (1950) global radial outflow hypothesis was contrasted with a simple extrapolation strategy. Second, backing-direction judgments capitalizing on the informational equivalence of global radial outflow created during forward ego-motion and global radial inflow during backward ego-motion were explored. In comparing the accuracy of heading and backing judgments, new insights about global flow and extrapolation strategies were found. Consistent with the hypothesis of an extrapolation strategy, Experiment 1 demonstrated that backing judgments were more accurate than heading judgments when linear observer motion was simulated by means of a point-light flow field. In this case, accuracy was higher with two-point-light displays (extrapolation) than with more complex displays (global flow). Experiment 2 showed that in cases where extrapolation was not possible, such as circular motion, no advantage of backing judgments could be found and judgments were generally less accurate. We conclude that, whenever possible, observers use extrapolation to determine their heading/backing. Only when global flow is the only good source of information do they rely on it.     

From Brouwerian Counter Examples to the Creating Subject

The original Brouwerian counter examples were algorithmic in nature; after the introduction of choice sequences, Brouwer devised a version which did not depend on algorithms. This is the origin of the creating subject technique. The method allowed stronger refutations of classical principles. Here it is used to show that negative dense subsets of the continuum are indecomposable.
