The DAPP–SF as a Screener for Personality Disorder in a Forensic Setting

Studies on the Dimensional Assessment of Personality Pathology–Short Form (DAPP–SF) have shown its ability to identify treatment-seeking patients with personality disorders. This study focuses on its screening potential for personality disorder in 89 criminal suspects (77 men, 12 women; M age = 37.0 years) undergoing residential pretrial psychological assessments in a high-security setting. It was expected that Structured Interview for DSM–IV Personality (SIDP–IV) criteria met for personality disorder(s) would be associated with higher DAPP–SF scores. A floor effect was found in DAPP–SF scores: The forensic population reported less personality pathology than the general population. Only moderate associations between DAPP–SF and SIDP–IV outcome were found. Receiver operating characteristic analysis showed that some DAPP–SF subscales did not exceed chance level in their ability to screen for personality disorders. It is concluded that the DAPP–SF has limited usefulness as a screener for personality disorders in a forensic pretrial setting. Alternative forensic screening instruments are presented.     

Polarity correspondence in metaphor congruency effects: structural overlap predicts categorization times for bipolar concepts presented in vertical space

Previous research has shown that words presented on metaphor congruent locations (e.g., positive words UP on the screen and negative words DOWN on the screen) are categorized faster than words presented on metaphor incongruent locations (e.g., positive words DOWN and negative words UP). These findings have been explained in terms of an interference effect: The meaning associated with UP and DOWN vertical space can automatically interfere with the categorization of words with a metaphorically incongruent meaning. The current studies test an alternative explanation for the interaction between the vertical position of abstract concepts and the speed with which these stimuli are categorized. Research on polarity differences (basic asymmetries in the way dimensions are processed) predicts that +polar endpoints of dimensions (e.g., positive, moral, UP) are categorized faster than -polar endpoints of dimensions (e.g., negative, immoral, DOWN). Furthermore, the polarity correspondence principle predicts that stimuli where polarities correspond (e.g., positive words presented UP) provide an additional processing benefit compared to stimuli where polarities do not correspond (e.g., negative words presented UP). A meta-analysis (Study 1) shows that a polarity account provides a better explanation of reaction time patterns in previous studies than an interference explanation. An experiment (Study 2) reveals that controlling for the polarity benefit of +polar words compared to -polar words did not only remove the main effect of word polarity but also the interaction between word meaning and vertical position due to polarity correspondence. These results reveal that metaphor congruency effects should not be interpreted as automatic associations between vertical locations and word meaning but instead are more parsimoniously explained by their structural overlap in polarities.     

The role of affect in attitudes toward organ donation and donor-relevant decisions

We argue that affect plays a vital role in attitudes toward organ donation and that reluctance to become an organ donor is likely to be related to the experience of affective ambivalence. Assessing the affect associated with organ donation could help to predict donor-relevant decisions. Results of a confirmatory factor analysis on 464 students showed that affective evaluations can be distinguished both from cognitive evaluations and from overall evaluations. As expected, affective evaluations revealed ambivalence (using the ‘Griffin’ measure of ambivalence) toward organ donation, whereas the two other types of evaluations did not. Results of a follow-up study using logistic regression (n?=?85), showed that affective evaluations predicted donor-relevant decisions six months later. The present findings support the proposal to include separate affective evaluations in measures of attitudes to organ donation. More general implications for the measurement and structure of attitudes in health related domains are discussed.

Abstract

This study examined the importance of the nature of the relationship between sexual partners in predicting types of sexual practices for 293 gay and bisexual men. Demographics, personal beliefs, substance use, and variables from the health belief model, theory of self-efficacy, and theory of reasoned action were used to predict sexual behaviors. Sexual practices varied by type of partner relationship and duration, with a higher probability of risky behaviors occurring with primary partners than with non-primary partners; relationship status also moderated the effects of safer sex partner norms and denial on sexual risk-taking. In addition, men who were younger, had less education, and used alcohol or drugs prior to sex engaged in higher risk behaviors. This study indicates that a more comprehensive assessment of dimensions of partner relationship will lead to greater understanding of sexual risk-taking.     

Brightness differences influence the evaluation of affective pictures

We explored the possibility of a general brightness bias: brighter pictures are evaluated more positively, while darker pictures are evaluated more negatively. In Study 1 we found that positive pictures are brighter than negative pictures in two affective picture databases (the IAPS and the GAPED). Study 2 revealed that because researchers select affective pictures on the extremity of their affective rating without controlling for brightness differences, pictures used in positive conditions of experiments were on average brighter than those used in negative conditions. Going beyond correlational support for our hypothesis, Studies 3 and 4 showed that brighter versions of neutral pictures were evaluated more positively than darker versions of the same picture. Study 5 revealed that people categorised positive words more quickly than negative words after a bright picture prime, and vice versa for negative pictures. Together, these studies provide strong support for the hypotheses that picture brightness influences evaluations.     

Unraveling Effects of Novelty on Creativity

Novelty is inherent to creative processes. A positive effect of novelty on creative task performance was therefore predicted. However, creativity can benefit from divergent, as well as convergent thinking. Subsequently, novelty may benefit creative performance when divergent thinking is required, but it could inhibit creative performance when convergent thinking is required. In Study 1, participants were primed with novelty or familiarity, and performed a creativity task that required divergent thinking. Results showed a beneficial effect of novelty priming on originality of the answers. In Study 2, a creativity task that required convergent thinking was framed as novel, familiar, or neutral. Results showed an inhibitory effect of novelty on creativity. Results are related to information processing styles, and implications for creativity and novelty research are discussed.     

How can you resist? Executive control helps romantically involved individuals to stay faithful

In the present research, we examined why some people have more difficulty than others in staying faithful to their romantic partners. Three studies supported our main prediction that executive control is associated with romantically involved individuals' ability to stay faithful. Study 1 showed that participants with a higher level of executive control reported less difficulty in staying faithful to their partners than did those with lower levels of executive control. In Study 2, romantically involved male participants were placed in a waiting room together with an attractive female confederate. Results showed that participants with a higher level of executive control showed less flirting behavior with the confederate than did those with lower levels of executive control. Study 3 demonstrated that a higher level of executive control was related to a lower expressed desire to meet an attractive other, but only for romantically involved participants. Together, these studies showed that executive control helps romantically involved individuals to deal with the lure of attractive alternatives.     

Does mimicking others change your self-view?

Does mimicking affect the way you think about yourself in relation to other people? In the present study, we instructed participants to either mimic or not mimic the expressions of their interaction partner. After a 3-minute interaction, participants' self-view in relation to others was measured. Results revealed that mimickers defined themselves more in relation to others than nonmimickers. Thus, mimicking others, compared to not mimicking others, changes your self-view.     

Measuring procedural imitation aptitude in children: further validation of the Preschool Imitation and Praxis Scale (PIPS)

The Preschool Imitation and Praxis Scale (PIPS) was developed to measure bodily and procedural imitation aptitude in young children. However, the investigation of procedural imitation is more complex than that of bodily imitation. The procedural imitation tasks of the PIPS mainly consisted of unusual acts upon objects (for example, switching on a lamp in a toy animal with the forehead). This study assessed the suitability of these tasks by ruling out nonimitative learning in 15 typically developing children between 12 and 55 mo. of age (6 girls, 9 boys). Results indicated that the tasks seem novel and unlikely to be performed spontaneously by the children. In addition, the number of target acts performed by the children in the imitation condition was significantly higher than in the baseline, investigator-manipulation, and imitation-enhancement nonimitative control conditions. Finally, the tasks elicited more frequently imitative behaviour than end-state emulation. Therefore, the tasks appear appropriate to measure procedural imitation, and the findings support the theoretical validity of the PIPS.
