Connecting terror management and dissonance theory: Evidence that mortality salience increases the preference for supporting information after decisions

From the perspective of terror management theory, reminders of mortality should intensify the desire to pursue cognitive consistency. The authors investigated this notion with regard to dissonance theory starting from the finding of research on "selective exposure to information" that after having made a decision, people prefer consonant over dissonant information. The authors found that following mortality salience, people indeed showed an increased preference for information that supported their decision compared to information conflicting with it. However, this only occurred with regard to a worldview-relevant decision case. For a fictitious decision scenario, mortality salience did not affect information seeking. Practical and theoretical implications are discussed.     

Information sampling and group decision making: the effects of an advocacy decision procedure and task experience

Group discussions tend to focus on information that was previously known by all members (shared information) rather than information known by only 1 member (unshared information). If the shared information implies a suboptimal alternative, this sampling bias is associated with inaccurate group decisions. The present study examines the impact of 2 factors on information exchange and decision quality: (a) an advocacy group decision procedure versus unstructured discussion and (b) task experience. Results show that advocacy groups discussed both more shared and unshared information than free-discussion groups. Further, with increasing experience, more unshared information was mentioned in advocacy groups. In contrast, there was no such increase in unstructured discussions. Yet advocacy groups did not significantly improve their decision quality with experience.     

An alternative perspective on von Winterfeldt et al.'s (1997) test of consequence monotonicity

D. von Winterfeldt, N.-K. Chung, R. D. Luce, and Y. Cho (1997) provided several tests for consequence monotonicity of choice or judgment, using certainty equivalents of gambles. The authors reaxiomatized consequence monotonicity in a probabilistic framework and reanalyzed von Winterfeldt et al.'s main experiment via a bootstrap method. Their application offers new insights into consequence monotonicity as well as into von Winterfeldt et al.'s 3 experimental paradigms: judged certainty equivalents (JCE), QUICKINDIFF, and parameter estimation by sequential testing (PEST). For QUICKINDIFF, the authors found no indication of violations of "random consequence monotonicity." This sharply contrasts the findings of von Winterfeldt et al., who concluded that axiom violations were the most pronounced under that procedure. The authors found potential evidence for violations in JCE and certainty equivalents derived from PEST.     

Visual search for dimensionally redundant pop-out targets: parallel-coactive processing of dimensions is location specific

Three visual search experiments investigated redundancy gains for single and dual odd-one-out feature targets that differed from distractors in orientation, color, or both. In Experiment 1, redundant-target displays contained (a) a single target defined in 2 dimensions, (b) dual targets each defined in a different dimension, or (c) dual targets both defined in the same dimension. The redundancy gains, relative to single nonredundant targets, decreased from the first condition on, with violations of J. Miller's (1982) race model inequality (RMI) manifested only in the first 2 conditions. Experiment 2 systematically varied the spatial separation between dual targets each defined in a different dimension. Violations of the RMI were evident only when the 2 targets occupied nearby locations. Experiment 3 provided evidence of RMI violations by dimensionally redundant targets at both precued (likely) and noncued (unlikely) display locations. Taken together, these results suggest that there is coactivation of a common mechanism by target signals in different dimensions (not by signals in the same dimension), that the coactivation effects are spatially specific, and that the coactivated mechanisms are located at a preattentive, perceptual stage of processing.     

The duration component of the stress effect in stuttering

The purpose of the present study was to investigate whether there is a relationship between stuttering on stressed syllables and the duration of these syllables. Sixteen adults who stutter read a text consisting of 226 syllables. The relative stress of each syllable was rated, and syllables were categorized into long- and short-stressed syllables, unstressed syllables and intermediate syllables lying in-between. In order to isolate effects caused by within-word position from those caused by linguistic stress, syllables in initial and in subsequent positions were analyzed separately. In both word position categories stressed syllables were stuttered more often than unstressed syllables. Stuttering frequency of intermediate syllables seems to be in-between stressed and unstressed syllables, just as their stress level is rated in-between. Results regarding the duration of stressed syllables do not allow final conclusions.

Educational objectives: The reader will learn about and be able to describe (1) language factors related with stuttering events, (2) the stress effect in adults who stutter, and (3) methods to control for its confounding variables.     

Direct and relational bullying among primary school children and academic achievement

The association between bullying behaviour and academic achievement was investigated in 1016 children from primary schools (6-7-year-olds/year 2: 480; 8-9-year-olds/year 4: 536). Children were individually interviewed about their bullying experiences using a standard interview. Key Stage I National Curriculum results (assessed at the end of year 2) were collected from class teachers, and parents completed a behaviour and health questionnaire. Results revealed no relationship between direct bullying behaviour and decrements in academic achievement. Conversely, higher academic achievement at year 2 predicted bullying others relationally (e.g. social exclusion at year 4). Relational victimisation, Special Educational Needs (SEN), being a pupil from a rural school or small classes and low socioeconomic status (SES) predicted low academic achievement for year 2 children. Findings discount the theory that underachievement and frustration at school leads to direct, physical bullying behaviour.     

Measure and integral with purely ordinal scales

We develop a purely ordinal model for aggregation functionals for lattice-valued functions, comprising as special cases quantiles, the Ky Fan metric and the Sugeno integral. For modelling findings of psychological experiments like the reflection effect in decision behaviour under risk or uncertainty, we introduce reflection lattices. These are complete linear lattices endowed with an order reversing bijection like the reflection at 0 on the real interval [−1,1]. Mathematically we investigate the lattice of nonvoid intervals in a complete linear lattice, then the class of monotone interval-valued functions and their inner product.     

Zur Bedeutung des Wahns für die Beurteilung der Schuldfähigkeit nach den §§ 20 und 21 StGB

For the assessment of criminal responsibility of offenders with symptoms of delusion it first has to be examined if one of the four basic elements of §§ 20, 21 of the German Penal Code is fulfilled. For this purpose a careful diagnosis of the type and intensity of the delusion and the underlying psychiatric disease is necessary. If a basic element is fulfilled the effect of the delusion on the ability of the offender to perceive the wrongful character of the act and to control behavior have to be discussed. For this the model of the anthropological cross developed by Winfried Brugger can be helpful.
