“Impossible figures” and interpretations of polyhedral figures

The concept “impossible figure” is analyzed by formalizing the interpretations of a polyhedral figure by an observer, and defining several types of inconsistency in such interpretations. Tests for these inconsistencies are developed using simple graph theory, and a sufficient condition is established for the feasibility of an interpretation. Finally, techniques are derived for the automatic construction of usual or unusual multibar figures.     

Forest lights: Notes on the conceptualization of the unconscious

Using the metaphor of lights appearing unexplained in the night, the author argues for a conceptualization of the unconscious based on a posture of trust and acceptance rather than one of fear and explanation.His last book,Idea and Experience, dealt with Husserl's project of phenomenology inIdeas I. He has recently completed another book,The Embers and the Stars: A Philosophical Inquiry into the Moral Sense of Nature.     

Subliminal stimulation, choice behavior and some personality correlates of subliminal sensitivity

The aim of this study was to investigate the possible relations between specific personality variables and the effect of subliminal stimulation on choice behavior. It was hypothesized that subjects with low anxiety, less neuroticism, and external locus of control and the trait of extraversion would be more susceptible to subliminal stimulation. 38 undergraduate students were exposed to subliminal messages urging them to choose symbols instead of numbers or letters. Analysis showed that subliminal stimulation did not generate a preference for symbols over numbers or letters. No support was observed for the hypothesis of an association between susceptibility and personality variables. These results may be explained in terms of symbol choice being a neutral message that did not relate to the subjects' needs and motivation.     

Organizational and family systems factors in stress among ministers

Forty-one Protestant ministers completed measures of stress-related symptoms, family of origin contact, church governing body density, history of pastor-parish conflict in the church, and a measure of Bowen's (1959b/1985) concept of emotional triangles. A denominational executive provided ratings of each church's history of pastor-parish conflict. Path analysis using multiple regression showed support for a model in which governing body density and history of conflict predicted emotional triangles, and emotional triangles predicted stress symptoms. Contact with the pastor's family of origin moderated the relationship between emotional triangles and stress symptoms. Results suggest that the organizational and family ecology of the ministerial role can be important in understanding occupational stress among ministers.     

Zur Geschichte und gegenwärtigen Lage der Philosophie in der ČSR

Official Czech philosophy has been dominated by a mix of Engelsian philosophy of science and positivism, a combination explained in part by the survival of positivism in Czechoslovakia and the failure of analytic philosophy to make inroads into Czech thinking. However, due to Jan Patoka's influence in espousing the works of Husserl and Heidegger, there was an anthropologically oriented Marxism (K. Kosik) although its successes were greater abroad than in Czechoslovakia. A more neopositivistic variant (L. Tondl) of Marxism also appeared, but it was a short-lived phenomenon without purchase on mainstream philosophy.A certain renewal of Czech philosophy was evident before 1968, once again largely due to Patoka's influence. Foreign guests who took part in informally organized, often secret, seminars and discussion groups were very instrumental in spreading new ideas. Despite these positive occurrences, Czech philosophy is experiencing a crisis at the level of the middle generation of non-academic, philosophically competent intellectuals among whom sceptical and nihilist attitudes prevail. A rebirth of spirit may be in the offing if the recovery of the specific sense of the Czech Reformation's idea of truth is pursued.     

Sensorimotor synchronization: Motor responses to regular auditory patterns

Subjects (N = 32) were asked to synchronize a motor response with tones in auditory patterns. These patterns were created from six tones and six intertone intervals of equal duration. The pitch of the first tone differed from the others. It was found that subjects used three types of timing in their motor response: (1) the first intertone interval was prolonged and the second interval was shortened, (2) the second intertone interval was prolonged and the first interval was shortened, and/or (3) the first interval and the second interval were of approximately the same length. The prolongation of the fifth interval was observed during all three types of timing. The results are explained using the concept of suprasegmental control of timing, which explains a prolongation of intervals at critical control point of the patterns. The occurrence of three different strategies of timing is discussed in connection with similar principles in musical performance.     

Toward understanding sex differences in pay allocation: Agency,communion, and reward distribution behavior

This research examined the extent to which the personality characteristics of agency and communion are sex linked, and the extent to which differences in these orientations can account for sex differences in reward distribution behavior. In two studies, the agency and communion level of large samples of male and female undergraduates were assessed. As expected, males were more agentic and females were more communal. Moreover, when subjects who scored high or low on agency and high or low on communion were asked to allocate rewards between themselves and a co-worker, these personality differences were related to their allocation decisions. These results were used as the basis for discussing the role that sex-linked personality differences might play in distributive justice judgments.This article is an adaptation of a colloquium presentation at the meeting of the American Psychological Association, Los Angeles, August 1981.

Does awareness of speech as a sequence of phones arise spontaneously?

It was found that illiterate adults could neither delete nor add a phone at the beginning of a non-word; but these tasks were rather easily performed by people with similar environment and childhood experiences, who learned to read rudimentarily as adults. Awareness of speech as a sequence of phones is thus not attained spontaneously in the course of general cognitive growth, but demands some specific training, which, for most persons, is probably provided by learning to read in the alphabetic system.
