Absence of an interaction between navigational strategies based on local and distal landmarks

In 3 experiments, rats were required to escape from a Morris pool by swimming to a submerged platform that was located at the apex of a notional, equilateral triangle with 2 different landmarks occupying the corners at the base. Training for 1 group was always conducted in view of the landmarks surrounding the pool and with the triangular array in a fixed orientation. Subjects could therefore identify the direction of the platform from a single landmark within the pool by reference to cues outside the pool or to the other landmark within the pool. Both strategies were used, and the results from additional groups revealed that the first of these strategies did not affect the acquisition of the second one.     

Interrater reliability in professional psychology student selection

High interrater reliability was noted among academics selecting students for professional psychology training. Women raters showed higher concordance than men, although all raters showed significant agreement about the male and the female applicants.     

The use of imagery in cognitive therapy for psychosis: a case example

There has been a long tradition of studying imagery in relation to psychotic symptoms. Recent studies have suggested that imagery may be involved in the development and maintenance of psychotic symptoms (hallucinations and delusions in particular). Following a review of this literature, including work conducted by the author and colleagues, a case study is used to illustrate the clinical applications of this work. Working with images that were associated with persecutory delusions appeared to contribute to a reduction in distress, preoccupation, and conviction in relation to these beliefs, which were assessed using a standardised measure (PSYRATS). The implications for theory, practice, and future research are considered.     

Contribution Patterns in Major U.S. Marital and Family Therapy Journals: 1992 Through 2002

The institutional sources of articles published between 1992 and 2002 in five major family therapy journals—the American Journal of Family Therapy, Contemporary Family Therapy, Family Process, Journal of Family Psychology, and the Journal of Marital and Family Therapy were reviewed. Noteworthy similarities and differences as compared to earlier reviews were found. While no single institution dominated in numbers of publications, six of the top 10 institutions found between 1980 and 1995 were also found to be within the top 10 most productive institutions between 1992 and 2002. Patterns and changes in contributions from international sources, as well as from institutions with a COAMFTE-accredited program are discussed. Contributions from private practitioners and clinicians are also addressed.     

Adolescent personality: a five-factor model construct validation

The purpose of this study was to investigate convergent and discriminant validity of the five-factor model of adolescent personality in a school setting using three different raters (methods): self-ratings, peer ratings, and teacher ratings. The authors investigated validity through a multitrait-multimethod matrix and a confirmatory factor analysis correlated trait, uncorrelated method model. With the exception of Emotional Stability, each analysis demonstrated similar patterns and together provided support for the convergent and discriminant validity of the five-factor model structure of adolescent personality. However, among the three raters, self-ratings of personality provided a comparatively weaker method for assessing adolescent personality. The influences of agreement between self and other raters are discussed in relation to contrast, perceiver, and target effects; expert observer effects; the degree of acquaintanceship; and the effect of the social context.     

Integrated versus segregated accounting and the magnitude effect in temporal discounting

Temporal discounting rates in humans generally decrease as the amount of reward increases, a phenomenon known as themagnitude effect. In the present study, we examined whether temporal discounting and the magnitude effect are related to segregation of choices in terms of gains or losses for waiting for or expediting receipt of a reward. Subjects (N = 24) responded to a series of hypothetical choices about amounts of money available either immediately or after a delay. The immediate and delayed amounts either were presented as integrated amounts in the baseline condition or were segregated as differential gains or losses for choosing delayed or expedited consumption (delay and speedup conditions, respectively). Temporal discounting rates decreased in the segregated conditions, in accord with the standard discounted utility model but contrary to the hypothesis that the subjects were choosing on the basis of reward differentials in the baseline condition. The size of the magnitude effect was comparable in the baseline and the delay conditions but decreased in the speed-up condition. These results challenge explanations of the magnitude effect in terms of an increasing proportional sensitivity property of the utility function (Loewenstein & Prelec, 1992) and the hypothesis that subjects choose on the basis of differentials even when the rewards are presented as integrated amounts.     

THE CHRISTIAN VIRTUE OF MERCY: AQUINAS' TRANSFORMATION OF ARISTOTELIAN PITY

In his discussion of the virtue of mercy (ST, II-II.30), Thomas Aquinas draws upon two seemingly opposed sources. On the one hand, Thomas takes Aristotle as an authority on the subject of compassion. Aristotle maintains in his discussion of pity in the Rhetoric that pity is felt for those who suffer undeservedly since we do not pity but rather blame those who suffer as a result of their own wicked actions. On the other hand, Jesus in Matthew's gospel feels pity for the crowds. 'At the sight of the crowds, his heart was moved with pity for them for they were troubled and abandoned, like sheep without a shepherd' (Matt.9:36). In his commentary on this text from Matthew, Thomas identifies two possible interpretations for the troubled and abandoned condition of the crowd. The crowd is said to be troubled in so far as it is vexed by demons and abandoned in so far as it lies prostrate because of infirmities. The crowd can also be said to be troubled in so far as it is vexed by errors and to be abandoned in so far as it is fallen because of sin. ¹ Jesus, then, according to Thomas and contrary to Aristotle's claim, feels pity for the crowds as a result of the crowd's misery brought on by their own sinful deeds.
In this paper, I examine how Thomas harmonizes these conflicting sources. More specifically, I hope to show both how Thomas uses Aristotle's observations on pity and at the same time transforms those observations in light of Christ's mercy on sinners. Thomas' use and transformation of Aristotle's account of pity provides an enlightening perspective from which to interpret Thomas' initially troubling claim that God feels no pity over the suffering of creatures, which we will consider briefly by way of a conclusion to this paper.
