The relationship between psychopathy and impulsivity: A multi-impulsivity measurement approach

Psychopathy is a serious personality disorder of which impulsivity is a key component. However, impulsivity is a multidimensional construct, with multiple approaches to measurement, and different measures may be differentially implicated in psychopathy. This study investigated the relationship between psychopathy as assessed by the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005), a personality measure of impulsivity (Barratt Impulsiveness Scale-11), and four behavioural measures of impulsivity (GoStop Impulsivity Paradigm, Two Choice Impulsivity Paradigm, Delay Discounting Task, Iowa Gambling Task). A nonclinical sample (N = 80) was recruited from the local community to advance understanding of psychopathy in non-incarcerated samples. The results indicated that the personality measure of impulsivity was strongly correlated with the PPI-R, while the behavioural measures were either not correlated or only weakly correlated with the PPI-R. The results are discussed in terms of the multifaceted nature of impulsivity and the need for the further development of behavioural measures of impulsivity, given their importance in clinical assessment and intervention.     

Is paranoia a defence against or an expression of low self‐esteem?

Paranoia has been hypothesized to be negatively correlated with self‐esteem. However, hypotheses differ about how low self‐esteem might produce paranoia. The paranoia as defense model views paranoia as a defensive reaction against low self‐esteem. In contrast, the paranoia as expression model views paranoia in part as a reflection of low self‐esteem. In the current study, paranoia was negatively associated with global explicit self‐esteem, self‐competence, self‐liking and self‐serving attributional style, but unassociated with implicit self‐esteem as measured with the Implicit Association Test. In contrast, facets of narcissism, which also have been hypothesized to be associated with defensive self‐processing, were associated with defensiveness. Overall, these results suggest that paranoia is better represented by the expression model. Copyright © 2010 John Wiley & Sons, Ltd.     

A pictorial attitude IAT as a measure of implicit motives

We tested the hypothesis that a pictorial attitude variant of the Implicit Association Test (PA‐IAT) is a valid measure of implicit motives. The PA‐IAT aims to capture attitudes towards pictures that are related to implicit motives. In the first two studies, we showed that the pictorial attitude Implicit Association Test (IAT) correlated more highly with non‐IAT measures of implicit motives than other IAT variants. In the third study, we established the validity of the PA‐IAT experimentally and showed that the pictorial attitude IAT correlated with non‐declarative behavioural measures only if implicit motives were aroused.

Human responding with mutual reinforcement: Baseline and effects of an intervention1

Pressing a key by one undergraduate provided another undergraduate with points exchangeable for money, and vice versa. Four types of response patterns were found. Points were often delivered with a delay from the last response or with no response. When a contingency that responses lost points (punishment) was added to participants who had emitted more responses than the partner had, their response rates decreased while the rates of their partners increased. These results demonstrate that, under the contingency of mutual reinforcement: (a) response patterns that had occurred between monkeys were replicated between humans; (b) obtained response‐reinforcer relations were different from those generally programmed in the basic reinforcement schedules; and (c) the behavior of the participant was controlled by changing the behavior of the partner.     

Physical,verbal, and relational forms of bullying among German students: age trends,gender differences,and correlates

A revised version of the Bully/Victim Questionnaire [Olweus, 1991] was given to 2,086 fifth–tenth grader students from schools in two German federal states. The results were analysed in terms of frequencies of self‐reports of different forms of bullying (physical, verbal, relational/indirect; for bullies and for victims), gender and grade differences. Overall, 12.1% of the students reported bullying others and 11.1% reported being bullied (victimisation). We classified 2.3% of the students as bully/victims due to their self‐report. Significantly more boys reported bullying others, regardless of bullying form, and significantly more boys than girls were classified as bully/victims. Although there was no gender difference for victimisation at all, boys reported significantly more often than girls being bullied physically. Besides, self‐reports of pure and overlapping forms of bullying behaviour (relational, verbal, physical) were analysed. With regard to age trends, students from middle grades reported the highest rates of bullying. Self‐reported rates of victimisation were higher for younger students, regardless of form of victimisation. Furthermore, class size was not linked to reports of bullying and victimisation. Results from logistic regression analyses emphasised that the variables “gender” and “grade” add significantly to the prediction of self‐reported bullying; “grade” and variables measuring impaired psychosocial “well‐being” of students at school (e.g., feeling of not being popular, negative attitude towards breaks) add significantly to the prediction of self‐reported victimisation. The results are discussed against the background of other study findings, accentuating the significance of gender‐ and age‐specific forms of bullying/victimisation. Aggr.

直接民主与间接民主--《代议制政府》的重新解读

直接民主与间接民主的问题,是当代政治哲学的一个热点。本文通过对密《代议制政府》的重新解读,澄清了直接民主和间接民主的关系。密尔系统地阐述了代议制民主的问题,他的间接民主理论中包含着直接民主的因素。一方面密尔把人民亲自参政的直接民主视为代议制民主的基础和前提,阐明了人民参政的直接民主的正当性、合理性;另一方面他又深刻地分析了人民参政的直接民主可能带来的弊病和危险。实际上,直接民主是一把双刃剑,它既可以成为克服暴政的武器,又可能导致多数的暴政;既可以成为自由的保障,也可能成为自由的敌人。因此,需要根据实际情况,扬利避害,在政治制度的设计中,正确地适度地运用直接民主的形式,保证人民的政治参与。     

Indirect directives in monological argumentation

The paper deals with sentence adverbials and clauses with the propositional content no doubt can be cast on ... and their occurrence in monological argumentative discourse. Such adverbials and clauses are regarded as illocutionary indicators of indirect directives aiming at the verbal behaviour of the reader, or, more precisely, at the omission of verbal activity on reader's part. Such attempts to influence the reader's behaviour can be both fair ones, to anticipate reader's objections, but also manipulative ones, so as to suppress them. That is why some general guidelines are given how to distinguish between the discourse-organizing and the manipulative function of indirect directives in concern.     

Tests for equality of several alpha coefficients when their sample estimates are dependent

In a variety of measurement situations, the researcher may wish to compare the reliabilities of several instruments administered to the same sample of subjects. This paper presents eleven statistical procedures which test the equality ofm coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. Since all of the procedures depend on approximate asymptotic results, Monte Carlo methods are used to assess the accuracy of the procedures for sample sizes of 50, 100, and 200. Both control of Type I error and power are evaluated by computer simulation. Two of the procedures are unable to control Type I errors satisfactorily. The remaining nine procedures perform properly, but three are somewhat superior in power and Type I error control.A more detailed version of this paper is also available.
