Behavioral studies in spontaneously hypertensive rats

In the present study we examined some behavioral patterns in spontaneously hypertensive (SHR) male rats as compared with Wistar (W) rats. The following methods were employed: open field test, two-way active avoidance, passive avoidance, shock-induced fighting, shock-induced suppression of drinking (conflict test), and dominant-subordinate behavior in rats competing for water. Spontaneously hypertensive rats showed higher level of locomotor activity, lower emotionality, lower anxiety level, increased acquisition of avoidance tasks, and enhanced dominance behavior. In addition, hypertensive rats were less aggressive in shock-induced fighting test. It is concluded, that spontaneously hypertensive rats seem to be hyperactive in terms of locomotor activity while their emotionality appears to be paradoxically reduced.     

Health Care Ethics Consultation: 'Training in Virtue'

In philosophy, intelligence is less important than character, or so Wittgenstein once argued. In this paper, in a similar vein, I suggest that in health care ethics consultation character is of preeminent importance. I suggest that the activity of ethics consultation can be understood as "training in virtue," and what distinguishes the good health care ethics consultant from his/her average colleague are differences in traits of character. The underlying assumption is that one's use of knowledge and abilities are ultimately a function of who one is and how one perceives and confronts situations of moral uncertainty and conflict. In discussing the original case presented by Mark Bliton, I focus on the virtues of wisdom, justice, courage, compassion and humility.     

Beliefs in Conspiracies

This study used canonical correlation to examine the relationship of 11 individual difference variables to two measures of beliefs in conspiracies. Undergraduates were administered a questionnaire that included these two measures (beliefs in specific conspiracies and attitudes toward the existence of conspiracies) and scales assessing the 11 variables. High levels of anomie, authoritarianism, and powerlessness, along with a low level of self-esteem, were related to beliefs in specific conspiracies, whereas high levels of external locus of control and hostility, along with a low level of trust, were related to attitudes toward the existence of conspiracies in general. These findings support the idea that beliefs in conspiracies are related to feelings of alienation, powerlessness, hostility, and being disadvantaged. There was no support for the idea that people believe in conspiracies because they provide simplified explanations of complex events.     

Lateral asymmetry in the perceived sequence of speech and nonspeech stimuli

The task was to estimate the position where a click had been superimposed in a spoken sentence. Experiment 1 confirmed Fodor and Bever’s observation of an ear-asymmetry effect: the click is located earlier when it is presented to the left ear and the sentence to the right ear than with the opposite arrangement. In Experiment 2, combinations of monaural and binaural presentations were considered. They made it possible to eliminate interpretations which link the laterality effect to the fact of reaching or not reaching a particular ear and showed that the relevant factor is the relative position of the stimuli in acoustic space. Experiments 3 and 4 explored the relation between spatial separation and perceived sequence in greater detail. The relation involves a plateau: when the click comes to the left of the speech, it is preposed to a degree which depends on the amount of spatial separation; but, when it comes to the right of the speech, separation is irrelevant and the mean error is of the same order of magnitude as in a control condition without separation.     

The artist as transgressor in Mandel'štam's poetry

In Mandel'tam's writing, artistic creativity is described as based on the indispensable yet contradictory modes of compliance and deviation. The artist, by his artistic nature, must be an obedient disciple to the tradition that inspires him, and, at the same time, a violator who renders what inspires him in an individual form. Thus, art implies iterability through novelty. In the totalitarian state, this double nature of art acquires a sinister context and brings the artist to an unavoidable conflict with the state. He has a choice between a servile compliance with the state's command and artistic independence. If the artist complies, he loses his ingenuity; if, on the other hand, he has the courage to break away from the established order, his fate is martyrdom. The criteria of truth and falsehood, the issue of loyalty, of compromise and collaboration or resistance become most relevant. Such words as outcast or non-contemporary acquire the meaning of non-collaborationist or enemy of the people. In the totalitarian state a genuine artist is viewed as a law-breaker, and his art leads him to crime. The notions of compliance and deviation cease being merely aesthetic terms and assume in Mandel'tam's poetry complex, subtle and tragic overtones.I would like to express my gratitude to John Barnstead, Thomas Blakeley, James Doull, Elena Glazov-Corrigan, Gregory Glazov, Leonard Kazdan, Peter Kussmaul, Malcolm Ross, Detlev Steffen, and Ieva Vitins for their valuable criticism, suggestions, and revisions of my English.     

The Perceived Advantages and Disadvantages of Presymptomatic Testing for Machado-Joseph Disease: Development of a New Self-Response Inventory

This study describes the construction of a self-response inventory to evaluate the perception of advantages and disadvantages of the Machado-Joseph disease presymptomatic testing, in 44 individuals at-risk for this disease. The results showed that the reliability of this inventory was satisfactory. Factor analysis revealed a bidimensional structure: perceived advantages (pros) and perceived disadvantages (cons) of presymptomatic testing. Social desirability was found unrelated to the total scores of our inventory. Additional correlation studies, with other scales, confirmed the convergent validity of the instrument. These results suggest adequate construct validity. This inventory thus seems to be a proper instrument to assess expectations involved in the decision-making process of Machado-Joseph disease presymptomatic testing.     

The influence of decision task and deliberation style on the verdict of the juries

The influence of decision task and deliberation style on the verdict of the juries. In the Kameda's Deliberation Style Model the emission of verdicts of responsibility when the deliberation style of the juries (elemental/compound) and the type of decision task (disjunctive/conjunctive) are jointly manipulated, is favoured in certain conditions. Given the consequences that these approaches could have in real judicial processes, this model is analyzed using a manslaughter crime under the Spanish judicial context conditions (nine members juries and seven or five members majorities emitting a verdict of guilty or not guilty, respectively). The obtained results indicated a better operation of the model when a conjunctive decision task was demanded.
