Stimulus imagery and the effect of response categorization on recall in retroactive inhibition

This study deals with the interaction between characteristics of stimulus-response encoding and the effect of response categorization on recall in an A-B, A-C paradigm. After a discussion of the results of previous experiments by the present author a ‘restricted-constraint hypothesis’ is formulated. It states that category information will be used if the stimulus provides for an amount of constraint that is not sufficient for direct retrieval but still enough for identifying the response after the list as a whole has been retrieved. In the case of a high amount of constraint however, direct retrieval of the response is possible and category cues are bypassed. This hypothesis is tested by varying the Imagery-value of the noun-stimulus. A first experiment is inconclusive since the categorization effect fails to materialize. The second experiment comes out as predicted.     

Self-disclosure: an attributional perspective.

This experiment examined the effect of timing of an intimate disclosure and assignment of responsibility for the event disclosed on interpersonal attraction. Subjects were induced to interact with a confederate who in all cases revealed something quite personal about himself. The disclosure occurred either early or near the end of a 10-minute conversation. The confederate accepted responsibility for the event disclosed, did not mention responsibility, or assigned responsibility to external factors. Negative traits were assigned to the early disclosure, and he was liked significantly less than the late discloser. The results are explained in terms of differential attributions made to early and late disclosures. The results for the assignment of responsibility variable were surprising: The confederate who accepted responsibility for the event disclosed elicited more negative reactions than the confederate who blamed other factors or who did not mention responsibility. Some possible reasons for this unexpected finding are discussed.     

Clause structure of sentences and speech processing

Listeners heard narrative stories in segments 20-60 sec long, and wrote their immediate recall for the most recent speech in each segment. Segments ended in four ways: there was a main clause alone, a subordinate clause alone, a main clause preceding a subordinate clause, or a subordinate clause preceding a main clause. Only these final sentences were well recalled. Of these, single-clause sentences were recalled best and two-clause sentences with main-subordinate clause order were recalled worst. An interaction obtained between clause position and function suggests that processing may be delayed when sentences fall to begin with main clauses.     

A new illusion: The underestimation of distance during pursuit eye movements

A new visual illusion is reported. The apparent distance through which a displaced target appears to move is significantly shorter when pursuit tracked than when that same distance is observed by means of a saccadic eye movement. This misperception of distance seems to be related to the Aubert-Fleischl paradox, the underestimation of the velocity of a tracked target, and to reveal a consistent characteristic of the pursuit eye movement system.     

Mathematics of Totalities: an alternative to mathematics of sets

I dare say, a set is contranatural if some pair of its elements has a nonempty intersection. So, we consider only collections of disjoint nonempty elements and call them totalities. We propose the propositional logicTT, where a proposition letters some totality. The proposition is true if it letters the greatest totality. There are five connectives inTT: , , , , # and the last is called plexus. The truth of # means that any element of the totality has a nonempty intersection with any element of the totality . An imbeddingG of the classical predicate logicCPL inTT is defined. A formulaf ofCPL is a classical tautology if and only ifG(f) is always true inTT. So, mathematics may be expounded inTT, without quantifiers.     

The impact of religion on men's blood pressure

Most clinical studies examining the relation between religion and blood pressure status have focused on church attendance, finding lower pressures among frequent attenders. The present study examines the effect on blood pressure status of a religious meaning variable, importance of religion, both by itself and together with frequency of church attendance. The relation between blood pressure, self-perceived importance of religion, and frequency of church attendance was examined among a rural sample of 407 white men free from hypertension or cardiovascular disease. The data confirmed an interaction between the effects of both religious variables on blood pressure status, with importance of religion having an even greater association with lower pressures than church attendance. Diastolic blood pressures of persons with high church attendance and high religious importance were significantly lower than those in the low attendance, low importance group. These differences persisted after adjusting the analyses for age, socioeconomic status, smoking, and weight-height ratio (Quetelet Index). The difference in mean diastolic pressures based on response to the religious importance variable alone was statistically and clinically significant, particularly among men aged 55 and over (6 mm) and among smokers (5 mm). These findings suggest that both religious attitudes and involvement may interact favorably in their effects on cardiovascular hemodynamics.     

The influence of an audience upon the reactions to filmed violence

In order to examine audience effects when viewing firmed violence, 5 to 6 year old pre-school boys who had been rated as submissive by their teachers watched an aggressive or a neutral movie either alone, accompanied by another submissive classmate, or a dominant one. Subsequent aggression against a frustrating, unknown and unseen boy was delivered via a modified Buss machine, especially adapted for children. Subjects accompanied by a dominant peer were more aggressive than the others but did not react differentially to the movies. Subjects tested alone were more aggressive after the violent film than after the neutral one and the opposite pattern occurred for the boys accompanied by a submissive classmate. These findings stress the importance of the social context when viewing filmed violence. It is suggested that the quality of the audience can have different directional (e.g. fear and aggression) as well as energizing properties. Links with the literature on social facilitation and audience effects are underlined.     

Set theory as modal logic

A logical systemBM ⁺ is proposed, which, is a prepositional calculus enlarged with prepositional quantifiers and with two modal signs, and These modalities are submitted to a finite number of axioms. is the usual sign of necessity, corresponds to transmutation of a property (to be white) into the abstract property (to be the whiteness). An imbedding of the usual theory of classesM intoBM ⁺ is constructed, such that a formulaA is provable inM if and only if(A) is provable inBM ⁺. There is also an inverse imbedding with an analogous property.
