The process of selective exposure: Why confirmatory information search weakens over time

The present research investigated whether the tendency to prefer decision-consistent to decision-inconsistent information after making a preliminary choice would vary during the sequential process of searching for additional pieces of decision-relevant information. Specifically, it was tested whether decision makers would be more confirmatory in their information evaluation and search at the commencement rather than end of an information search process. In fact, five studies revealed that participants exhibited stronger confirmatory tendencies in both information evaluation (Studies 2 and 5) and search (Studies 1, 3, and 4) immediately after making a preliminary decision compared to during the later stages of an information search process. With regard to the underlying mechanism, results further revealed that individuals appear to be more motivated to detect the best decision alternative at the beginning (as opposed to the end) of an information search process, which leads to increases in confirmatory information processing during these stages.     

The temporal dynamics of effect anticipation in course of action planning

"Strong" versions of the ideomotor theory of action control claim that anticipations of the environmental effects that actions bring about are mandatory for response selection. This is considered to be the one and only way of how actions can be voluntarily selected. We studied this notion in a series of four experiments where we adapted the flanker paradigm to investigate the involvement of effect codes in the preparation of motor responses. Participants first learned that their responses to stimulus letters were contingently followed by the presentation of a new letter on the screen. In the second phase of the experiments, the action-demanding letters were presented together with the effects of the correct response, effects of other responses, or neutral letters. Varying the stimulus onset asynchrony (SOA) between target stimuli and the flanking effect stimuli provides the opportunity to investigate the temporal dynamics of the activation of effect codes. Hence, flanker stimuli were presented before, simultaneously with, or after the onset of the target. The results indicate that effect-related information from the flanker stimuli is involved in the preparation process, but mainly in later phases of response preparation. The observed pattern of results suggests that, at least under conditions where responses are determined by stimuli, effect codes are activated in course of response planning to enable the evaluation of the executed response and the monitoring of response execution, but they do not automatically activate the responses themselves.     

Differentialdiagnose bei Morbus Parkinson

Herr F. J., geboren 1941, wurde von seinem sehr aufmerksamen Internisten in meine Ordination geschickt (herzlichen Dank an dieser Stelle an den Kollegen!). Zuvor waren bereits zun?chst Morbus Parkinson und danach Essenzieller Tremor diagnostiziert worden. Wie kommt man hier mit der Diagnostik rein klinisch weiter? Wo sind die kritischen Details?     

Zur Gefährlichkeit ehemaliger Patienten des Maßregelvollzugs (§ 63 StGB)

Background

The prediction of dangerousness in mentally ill offenders – and here mainly the issue of safety – is still of primary interest for forensic experts and also the public. The effectiveness of treatment and therefore of the whole German forensic system is generally measured by recidivism rates of this clientele.

Methods

The Essen prospective Multi-Centre Prognosis Study began in 1997, and 23 forensic hospitals in Germany took part. Data of 321 subjects were collected with a follow-up of up to 10 years (mean 7.5 years). This article presents topical recidivism rates.

Results

Currently the general recidivism rate is 31.5% and for severe reoffences 10.3% which is relatively low in comparison to other recent studies.

Conclusions

The rate of general recidivism of forensic patients in Germany has been reduced in the last years while the rate of severe reoffence was constant. In order to reduce the number of reoffences further studies should analyze the forensic aftercare.     

Information search and presentation in advisor–client interactions

When making a decision, people often search for more information supporting than conflicting with their preferred alternative. This can be counterproductive because potential risks and liabilities of the intended decision may be overlooked. However, when confronted with a decision problem, people often turn to advisors for help. We examined what kind of information advisors search for when confronted with a client’s decision problem and what information they present to their clients. Experiment 1 suggested that advisors (participants in the role of travel agents or friends) conducted a more balanced information search than personal decision-makers. However, when presenting information to their client, mock travel agents passed on more information supporting their recommendation than conflicting with it, whereas friends presented information in a balanced way. Experiment 2 replicated the balanced information search of advisors and suggested that this effect was partly mediated by the advisors’ increased accuracy motivation. Practical and theoretical implications are discussed.     

The influence of infant irritability on maternal sensitivity in a sample of very premature infants

The relationship between maternal sensitivity and infant irritability was investigated in a short‐term longitudinal study of 29 very preterm infants. Infant irritability was assessed at term with the Brazelton NBAS, the Mother and Baby Scales (MABS) and the Crying Pattern Questionnaire (CPQ). Maternal sensitivity was assessed by nurses' ratings in the neonatal care unit and at three months during mother–infant interaction observation. Cross‐lagged panel analysis indicated that neonatal irritability did not influence sensitivity at 3 months nor did maternal sensitivity in the newborn period lead to reduced irritability at 3 months. Both irritability and maternal sensitivity showed moderate stability over time (r = 0.55 and r = 0.60, respectively). It is concluded that in early infancy maternal sensitivity shows little influence on infant irritability in very preterm infants. Copyright © 2003 John Wiley & Sons, Ltd.     

Psychological effects of the Euro—experimental research on the perception of salaries and price estimations

In five studies we show that the introduction of the Euro influences price estimations and the perception of salaries among people in Germany. People confronted with wages given in Euros compared to the German Mark (DM) showed a reduced willingness to face long distances to get to work when accepting a job offer. When asked to price various consumer goods appropriately, they estimated higher prices if they used the ‘Euro’ currency compared to price estimations made in DM. This phenomenon only occurred with regard to the Euro, but not in comparison with other currencies (cf. the British Pound and Austrian Schilling). The differing price estimations between the Euro and the German Mark were not influenced by participants' attitude towards the Euro. Moreover, it turned out that they depended on how the judgement context was framed. Only if participants expected to make price estimations for shops in their home country, Germany, did the familiar nominal DM figures serve as an anchor heightening the estimated prices in Euro. The same effect disappeared if participants were instructed to make their price estimations for shops in a foreign country (Ireland). Copyright © 2002 John Wiley & Sons, Ltd.     

On the relations between crowding and visual masking

To study the question of which processes contribute to crowding and whether these are comparable to those of visual temporal masking, we varied the stimulus onset asynchrony (SOA) between target and flankers in a crowding setting. Monotonically increasing Type A masking functions observedfor small spacings and large eccentricities indicate that the integration of information from target and flankers underlies crowding. Decreasing masking functions obtained for large spacings and small eccentricities relate processes of crowding to those contributing to Type B masking. In addition, Type B masking was more frequent with letter-like nonletter flankers than with letter flankers, suggesting that Type B masking, just like crowding over large areas, is due to higher level interactions. The rapid decrease of the effects of interletter spacing and eccentricity with increasing SOA indicates that positional information is transient.     

Spared access to idiomatic and literal meanings: a single-case approach

The current study examines how patients with aphasia access the meanings of idioms during spoken sentence comprehension. In our experiment, we had 4 subjects whose native language is German: 2 left-hemisphere damaged patients (Wernicke's and global aphasia); 1 right-hemisphere damaged patient; and 1 age-matched healthy speaker. Ambiguous two-element German noun compounds carrying an idiomatic as well as a literal meaning served as target words. While listening to contextually biasing sentences containing the target words, the subjects performed a lexical decision task at the offset of each compound. All the subjects, including the aphasic patients, accessed the compounds' literal and idiomatic meanings simultaneously despite the existence of contextually biasing sentences. The data are discussed by taking account of the findings of recent studies of lexical semantic processing in aphasia.     

"It's not my fault--but only I can change it": counterfactual and prefactual thoughts of managers

In testing for the self-serving bias in performance evaluation, the authors propose that comparing managers' counterfactual and prefactual thoughts about subordinates' performance is more conclusive than the attributional approach and also offers practical advantages. In a study with 120 managers, a 4-way interaction of subordinate performance, temporal perspective, direction, and reference confirmed the predicted pattern. Managers' thoughts about how a weak performance could have been enhanced had external references, but thoughts about how such a performance could be enhanced in the future focused on the leader. This asymmetry was only observed for weak performance. Results are discussed with regard to biases in leaders' performance evaluations and to how counter- and prefactual thoughts could be used for leadership research and practice.
