The effects of urine on aggressive responses by male golden hamsters

Twenty adult male golden hamsters were isolated into individual cages for a period of six weeks, at the end of which time they had introduced into their home cages, on three occasions, a castrated male intruder. On each occasion the castrated intruder was daubed on the anogenital region with urine from one of three sources: (1) intact females, (2) other castrated males, and (3) intact males. Urine from a different source was applied to the castrated intruder on each of the three tests. Resident males consistently showed more aggression, sniffing, and following and less defensive behavior than the intruders. However, aggression by the resident males showed a significant variance over the three urine treatments given to the intruder. It is concluded that like male mouse urine, male hamster urine contains attack-provoking cues, but that unlike that of the mouse, female urine does not appear to be attack-inhibiting in this species.     

Spatial navigation: Cognitive variables involved in route retracing among an elderly population

The cognitive processes involved in route retracing are not well known. This study aims to highlight them in an elderly population in which contradictory results have been obtained, certain studies showing specific difficulties for route retracing, others not. Thirty-nine elderly subjects performed a route-learning task (forward-backward) in a garden, then completed spatial knowledge tasks and standardised cognitive tests. Results show four factors that were predictive of route retracing performance: route repetition, the pointing task, and two standardised cognitive tests, one assessing spatial working memory, and another global cognitive efficiency. According to these results, route retracing involves route and survey knowledge (i.e., egocentric and allocentric strategy), and the integration of forward-backward perspectives is underpinned by the spatial working memory. Moreover, the subjects did not make more errors in route retracing than in the route repetition task, suggesting that a real environment could compensate for a failing allocentric strategy.     

The generation effect: Further tests of the lexical activation hypothesis

Three experiments compared recognition memory for word versus nonword responses when they had been either read or generated using a rhyme rule and either a word or nonword stimulus. That is, either the wordshop or the nonwordthop was generated from either the wordchop or the nonwordphop. In Experiment 1, the lexicality of the stimulus and response terms was manipulated orthogonally between subjects; in Experiments 2 and 3, it was manipulated orthogonally within subjects. In Experiment 3, subjects also made a lexical (word-nonword) decision about each response term after it had been read or generated. In all three experiments, memory performance was better for generated than read responses. This generation effect occurred only if the response term was a word, regardless of whether the stimulus term was a word or a nonword. These results are discussed in terms of the roles that lexical memory and response unitization play in the generation effect.     

Computer-controlled displays of bending motions

This paper describes a physical model and the mathematical equations specifying the dynamics of a bending line. A computer program is also described that will control real-time displays of a line of points in three-dimensional space and collect psychophysical data from human observers discriminating between different bending motions.     

West Indian teachers', parents', and students' attitudes toward adolescent behavior problems

Attitudes toward adolescent behavior problems were surveyed using samples of teachers, parents, and secondary school students in Barbados. Fifty-two behaviors were rated for their impact on students' school and general social adjustment. Results revealed high positive correlations between groups in terms of ranked positions of problems, and also between rankings of problems of both boys and girls. However, parents rated the majority of problems higher (more serious) than did teachers, while adults generally awarded higher ratings than did male students, especially for conduct problems. Female students' responses were highly similar to those of adults, except in respect to heterosexual activity, which they rated more serious in boys, while most adults rated it much more serious in girls. Implications for discipline and guidance are considered.     

Anxiety and depression in women with advanced cancer: Implications for counselling

Fifty-three patients with advanced cancer were studied prospectively for 6 months to assess whether the site and method of chemotherapy administration influence levels of anxiety and depression. Patients received chemotherapy either at home or in hospital. Cases of clinical anxiety (36%) and depression (27%) were highest in the hospital treated group during the middle period of therapy. Patients treated at home had a lower psychiatric morbidity for anxiety (21%) and depression (21%) at the same period. There was no statistically significant difference in the mean scores on anxiety and depression between the groups. Overall, anxiety was more prevalent than depression. This study indicates that a minority of patients with advanced cancer treated by chemotherapy experience measureable psychiatric morbidity. Counselling services should be provided for these women throughout treatment, not just at the outset.     

Kierkegaard's ironic ladder to authentic faith

I would like to express my gratitude to Jonathan Rée for his valuable comments on the first draft of this paper, which is a shorter version of a chapter of myA Search for Authenticity, to be published by Routledge, London.     

PERCEPTIONS OF BEHAVIORAL CONSISTENCY:

Abstract— Actors view behavior relevant for personality traits as more variable than observers do. This study was designed in replicate this actor-observer effect (AOE) in a common-target paradigm, test whether actors, observers, or both are intuitively aware of the AOE, and examine the effects of social projection on people's awareness of the AOE. Within each actor-observer pair, subjects described the actor on a series of trait adjectives and rated the consistency of relevant behavior. They then predicted the other person's ratings. The AOE emerged, and actors, but not observers, were aware of the effect On average, actors correctly predicted that observers rated actors' behavior as more consistent than actors themselves did Correlational analyses showed that actors and observers were equally prone to project their own ratings lo their matched partners
