Myopic regret avoidance: Feedback avoidance and learning in repeated decision making

Decision makers can become trapped by myopic regret avoidance in which rejecting feedback to avoid short-term outcome regret (regret associated with counterfactual outcome comparisons) leads to reduced learning and greater long-term regret over continuing poor decisions. In a series of laboratory experiments involving repeated choices among uncertain monetary prospects, participants primed with outcome regret tended to decline feedback, learned the task slowly or not at all, and performed poorly. This pattern was reversed when decision makers were primed with self-blame regret (regret over an unjustified decision). Further, in a final experiment in which task learning was unnecessary, feedback was more often rejected in the self-blame regret condition than in the outcome regret condition. We discuss the findings in terms of a distinction between two regret components, one associated with outcome evaluation, the other with the justifiability of the decision process used in making the choice.     

Position-dependent and position-independent attention shifts: Evidence against the spotlight and premotor assumption of visual focussing

Summary One implication of the spotlight metaphor of visual-attention shifts is that attention moves from position to position, from one object in the visual field to another. According to this view, attention shifts start at the last-focussed position, their spatiotemporal course therefore being position dependent. A different, yet also position-dependent, formulation is implied in the so-called premotor hypothesis of attention (Rizzolatti et al., 1987; Umiltà et al., 1991). In this paper these two accounts are tested against an alternative, position-independent conception. It is maintained that in the case of onset-triggered processes, the course of the attentional shifts is independent of the last-focussed position.On the basis of these considerations, three experiments measure choice-reaction times of stimuli at different spatial positions after peripheral cuing of the same or another position within the visual field. Results show no evidence for the position-dependent conception of the spotlight metaphor or the premotor hypothesis with a long SOA (stimulus-onset asynchrony) between cue and stimulus. Only with a short SOA is the premotor hypothesis supported by the data. As an alternative interpretation, a position-independent thesis is favored, in which it is assumed that attention shifts can be adjusted during an early stage of processing.     

Detecting and identifying response-compatible stimuli

Previous work indicates that action-control processes influence perceptual processes: The identification probability of a left- or right-pointing arrow is reduced when it appears during the execution of a compatible left-right-key press (Müsseler & Hommel, in press). The present study addresses the question of whether this effect would also be observed in a detection task—that is, with judgments that do not require discriminating between left- and right-pointing arrows. Indeed, we found comparable effects in both the identification task and the detection task. This outcome is interpreted within a commoncoding framework, which holds that stimulus processing and action control operate on the same codes.     

Preference of dissonance reduction modes as a function of their order,familiarity and reversibility

Two central hypotheses of the original version of the theory of cognitive dissonance (Festinger, 1957) (1) that dissonance is to be conceived of as a primary drive and (2) that in order to reduce dissonance less resistant cognitions will be changed more than highly resistant ones led to hypotheses which were confirmed by two experiments. In Experiment I, a 2 × 3 factorial design, order and familiarity of dissonance reduction modes were manipulated. After receiving a dissonant information the subjects were offered a relatively low and a relatively high resistant cognition for dissonance reduction, each being placed first (series I, high-low resistance) or last (series II, low-high resistance) respectively. Subjects did (known) or did not (unknown) read these modes before reacting to them. Under the unknown condition dissonance will be reduced more with a specific mode if it is placed first than last. With known reduction modes the order of presentation does not have an effect. Under series I condition the first-placed, higher-resistant cognition will be changed more in the unknown condition than in the known condition. Under the series II condition the first-placed, lower-resistant cognition will be changed equally in the known and unknown condition. In short, the higher-resistant cognition will be changed more, only when it is placed first and when the following modes are not known. Two explanations for these results are possible: (1) The more dissonance is reduced by changing a more or a less resistant congnition, the less further reduction is necessary; (2) dissonance will be reduced in an internally consistent way. Experiment II excluded the first explanation. Subjects were allowed to revise their original way of reducing dissonance. First, subjects in one condition received series I unknown and subjects in the other condition received series II unknown. Reacting to the dissonance reduction modes the second time, there was more revision when the high-resistant congition was placed first (series 1 revision) than when placed last (series II revision). These results support the hypothesis that dissonance reduction by changing a less-resistant congnition more and changing a high-resistant one less is preferred. Implications of the results of the two experments for the stability of dissonance reduction, the method and interpretation of dissonance experiments are discussed.     

The case against coronary artery surgery

Coronary by-pass surgery has been performed in hundreds of thousands of patients in the last 15 years with a high standard of technical and surgical perfection. The indications for this kind of surgery, however, are still controversial because in spite of many retrospective and several prospective studies it cannot be proven convincingly that in a given patient this surgical procedure will prolong life or prevent myocardial infarction. The present attempt to analyze the causes for this controversy shows that the main reasons for this uncertainty lie: (a) in the enigma of the underlying (ischemic heart) disease itself, which is supposed to lend itself to surgical therapy; (b) in the inadequate methods available up until now for characterizing the state of the disease, its probable course, and its pathogenesis; and (c) in the professional group interests which have a momentum of their own.     

Amygdala activation during masked presentation of emotional faces predicts conscious detection of threat-related faces

It has been argued that critical functions of the human amygdala are to modulate the moment-to-moment vigilance level and to enhance the processing and the consolidation of memories of emotionally arousing material. In this functional magnetic resonance study, pictures of human faces bearing fearful, angry, and happy expressions were presented to nine healthy volunteers using a backward masking procedure based on neutral facial expression. Activation of the left and right amygdala in response to the masked fearful faces (compared to neutral faces) was significantly correlated with the number of fearful faces detected. In addition, right but not left amygdala activation in response to the masked angry faces was significantly related to the number of angry faces detected. The present findings underscore the role of the amygdala in the detection and consolidation of memory for marginally perceptible threatening facial expression.     

Cultural estrangement: the role of personal and societal value discrepancies

Study 1 examined whether cultural estrangement arises from discrepancies between personal and societal values (e.g., freedom) rather than from discrepancies in attitudes toward political (e.g., censorship) or mundane (e.g., pizza) objects. The relations between different types of value discrepancies, estrangement, subjective well-being, and need for uniqueness also were examined. Results indicated that personal-societal discrepancies in values and political attitudes predicted estrangement, whereas mundane attitude discrepancies were not related to estrangement. As expected, value discrepancies were the most powerful predictor of estrangement. Value discrepancies were not related to subjective well-being but fulfilled a need for uniqueness. Study 2 replicated the relations between value discrepancies, subjective well-being, and need for uniqueness while showing that a self-report measure of participants' values and a peer-report measure of the participants' values yielded the same pattern of value discrepancies. Together, the studies reveal theoretical and empirical benefits of conceptualizing cultural estrangement in terms of value discrepancies.     

SCIENCE-AND-RELIGION AND THE SEARCH FOR MEANING

Abstract. A survey and interpretation is offered of the broad range of contemporary thinking that concerns itself with the relationships between religion and science. The survey consists of a spectrum of six types of thought: (1) The modern option: translating religious wisdom into scientific concepts; (2) the postmodern/new-age option: constructing new science-based myths; (3) the critical post-Enlightenment option: expressing the truth at the obscure margin of science; (4) the postmodern constructivist option: fashioning a new metaphysics for scientific knowledge; (5) the constructivist traditional option: interpreting science in dynamic traditional concepts; (6) the Christian evangelical option: reaffirming the rationality of traditional belief. The interpretive effort considers these options under the rubric of the contemporary search for meaning and takes note of controversy and convergence within this search. Thinking on the religion/science interface is representative of much contemporary thinking that deals with the question of meaning in the present intellectual and cultural situation.     

Beholding the beholder: The reception of “Dutch” painting

While a lucid and understandable interpretation can be given for most pictures, typically Dutch paintings (i.e. seventeenth-century genre and still-life pictures) seem to allow for or even demand some measure of freedom for the beholder. The cause of this ambiguity lies in the typically Protestant disregard for works of art and in a concomitant characteristic of these works: they address the viewer in an ethical manner.In memoriam Sixten Ringbom, 1935-1992
