Less may be more when choosing is difficult: Choice complexity and too much choice

Although consumers readily seek choice and abundance, the so-called too-much-choice effect suggests that having many alternatives to choose from eventually leads to negative consequences, such as decreased post-choice satisfaction. The present research extends this research by highlighting the role of choice complexity. It is argued that too-much-choice effects are associated with choice complexity, which is influenced not only by the number of alternatives, but also by other features of the choice set, such as the number of attributes that alternatives are differentiated upon. These other influences of choice complexity may propel or hinder the emergence of too-much-choice effects. Two experiments tested this hypothesis by orthogonally manipulating the number of alternatives and the number of attributes. Results revealed a too-much-choice effect when alternatives were differentiated on many attributes, but not when alternatives were differentiated on few attributes. Implications for theory and practice are discussed.     

An inkblot for sexual preference: a semantic variant of the Affect Misattribution Procedure

A newly developed Semantic Misattribution Procedure (SMP), a semantic variant of the Affect Misattribution Procedure (AMP), was used in three studies as an indirect measure of sexual interest. Using a known-group approach, homosexual men (Studies 1 and 2), heterosexual men (Studies 1 to 3) and heterosexual women (Study 3) were asked to guess the meaning of briefly presented Chinese ideographs as "sexual" or "not sexual". The ideographs were preceded by briefly presented primes depicting male and female individuals of varying sexual maturity. As hypothesised, the frequency of "sexual" responses increased after priming with pictures of individuals of the preferred sex and increasing sexual maturation. The SMP showed satisfactory reliability and convergent validity as indicated by correlations with direct and two indirect measures of sexual interest. In two further studies, the hypothesised pattern was replicated whereas a standard AMP with the identical prime stimuli did not produce this result. The potential usefulness of semantic variants of the AMP is discussed.     

Left or right? Sources of political orientation: the roles of genetic factors, cultural transmission, assortative mating, and personality

In this study, we used an extended twin family design to investigate the influences of genetic and cultural transmission as well as different sources of nonrandom mating on 2 core aspects of political orientation: acceptance of inequality and rejecting system change. In addition, we studied the sources of phenotypic links between Big Five personality traits and political beliefs using self- and other reports. Data of 1,992 individuals (224 monozygotic and 166 dizygotic twin pairs, 92 unmatched twins, 530 spouses of twins, 268 fathers, and 322 mothers) were analyzed. Genetically informative analyses showed that political attitudes are genetically but not environmentally transmitted from parents to offspring and that a substantial proportion of this genetic variance can be accounted for by genetic variance in personality traits. Beyond genetic effects and genotypic assortative mating, generation-specific environmental sources act to increase twins' and spouses' resemblance in political beliefs. The results suggest multiple sources of political orientations in a modern democracy.     

Psychodynamische Aspekte der Ged?chtnisfunktionen

Based on Freud??s early thinking this paper tries to give an overview about the current state of the art related to psychodynamic aspects of memory functions. Freud began with the investigation of retrieval alterations, especially keeping content away from the experiencing ego to avoid unpleasurable states. Under the influence of new knowledge about war neuroses he tried to tackle the question of what might happen to the memory system if in the encoding situation the protecting shield is broken down through the impact of the stimuli. He came to the conclusion that such situations might lead to an omnipresence of the destructive content which could no longer be subsumed under the pleasure principle. Their permanent presence and the defense against them form the difference between traumatic disturbances and those based on unconscious conflicts. Most processes cannot be subsumed under repression but as a change of reality perception. It is shown that the models explaining the change from one state to the other is still not satisfactory. The analysis of peritraumatic states make it clear that they alone, like dissociative states, have an influence but posttraumatic experiences are just as decisive for the future development leading either to a pathogenic unconscious conflict or long-term posttraumatic disturbances with all kinds of comorbid states or healing.     

On the Ease of (Dis)believing: The Role of Accessibility Experiences in Credibility Judgments

Credibility judgments are common and consequential in many applied settings. Although much research has addressed human observers' ability to discriminate true and deceptive statements, less is known about the psychological processes involved in such judgments. Here, it is proposed that the process of mustering evidence for or against credibility is reflected in a feeling‐based form (ease‐of‐retrieval) and that such feelings can be used as a basis for credibility judgments. The results of an experiment show, as predicted, that the perceived ease with which participants could identify clues strongly influenced credibility judgments. Ironically, mustering more clues in support of a truthful account lowered credibility judgments; in contrast, mustering more clues in support of a deceptive account increased credibility judgments. Mediation analyses suggest that this is because participants relied on a feeling‐based as opposed to content‐based judgment strategy. Practical implications are discussed, and theoretical issues regarding the process of credibility judgment are raised. Copyright © 2012 John Wiley & Sons, Ltd.     

Comparability of Self‐Reported Conscientiousness Across 21 Countries

In cross‐national studies, mean levels of self‐reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self‐report judgements in relation to culture‐specific standards (often called the reference group effect), thereby undermining the cross‐cultural comparability of the judgements. We employed a simple method called anchoring vignettes in order to test whether people from 21 different countries have varying standards for Conscientiousness, a Big Five personality trait that has repeatedly shown unexpected nation‐level relationships with external criteria. Participants rated their own Conscientiousness and that of 30 hypothetical persons portrayed in short vignettes. The latter type of ratings was expected to reveal individual differences in standards of Conscientiousness. The vignettes were rated relatively similarly in all countries, suggesting no substantial culture‐related differences in standards for Conscientiousness. Controlling for the small differences in standards did not substantially change the rankings of countries on mean self‐ratings or the predictive validities of these rankings for objective criteria. These findings are not consistent with mean self‐rated Conscientiousness scores being influenced by culture‐specific standards. The technique of anchoring vignettes can be used in various types of studies to assess the potentially confounding effects of reference levels. Copyright © 2011 John Wiley & Sons, Ltd.
