Assessing Interpersonal Aspects of Schizoid Personality Disorder: Preliminary Validation Studies

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM–SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM–SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.     

Disentangling the belief in God and cognitive rigidity/flexibility components of religiosity to predict racial and value-violating prejudice: A Post-Critical Belief Scale analysis

Past research indicates that being religious is associated with prejudice toward racial and value-violating out-groups. However, this past research treated religiosity as a unidimensional construct without taking into account how different components of religiosity—belief in a higher power and the rigidity/flexibility of religious beliefs—are associated with measures of prejudice. Two studies examined the relationship between these two components of religiosity, as measured by the Post-Critical Beliefs Scale, and racial (African Americans, Arabs) and value-violating prejudices (atheists, gay men). As the flexibility of religious beliefs increased (literal vs. symbolic dimension), attitudes toward racial and value-violating out-groups became more positive (Study 1). As belief in God strengthened (exclusion vs. inclusion of transcendence dimension), attitudes toward value-violating out-groups became more negative. Study 2 demonstrated that these two components of religiosity fully mediated the relationship between general religiosity and prejudice toward African Americans, Arabs, and gay men and partially mediated the relationship between religiosity and prejudice toward atheists. Results are discussed in light of reexamining the conclusion that simply being religious is associated with prejudice.     

The attribution of intentionality: the role of skill and morality

The present study contributes to the discussion on the different components which constitute the intentionality concept about an undesired side effect, focusing on the morality and the skill. Two hundred and forty participants were asked to read a brief story about a car accident, in which it was explained the motivation of the high speed and objective and subjective skill of the agent to drive the car, and to fill in six questions about intentionality, objective risk, mental representation of risk, risk acceptance and blameworthiness for the outcome. The principal results showed that when the motivation is morally negative, people judge the side effect more intentional, also because they make more severe judgments about risk and blameworthiness. Moreover, when people are objectively proficient to perform the action (objective skill) the side effect is considered less risky and intentional and, in the case of a negative outcome, they are judged less severely than if they have a poor ability. Finally, a self-assessment of low skill to make the action (subjective skill) leads people to assess higher risks and, consequently, more intentionality for the side effect. The results are discussed on the basis of the literature about some specific components that make up the intentionality concept.     

The legacy of Adolf Meyer’s comparative approach: Worcester rats and the strange birth of the animal model

The breeding of albino rats had an enormous impact on experimental psychology in the twentieth century: Rats were, and for many questions still remain, the “standard animal” for laboratory research in neurology, psychology, and physiology. Albert Meyer was one of the figures most responsible for developing the albino rat as an experimental model. Despite Meyer’s pioneering work with albino rats, his rat research has received only sparse attention. Little is known about the way in which the animal served Meyer’s more famous psychiatric program. In this article, the author discusses the role that albino rats played in Meyer’s animal research. He then turn to the contrast between the way in which Meyer viewed the animal’s role in research and the way rats were later used as a laboratory “standard” to assure scientific generality. This comparison highlights the changes that occurred in comparative psychology in the twentieth century, and it further clarifies some of the concerns associated with the use of animal models today.
