Attitudes Toward Male Oral Contraceptives: Implications for Models of the Relationship Between Beliefs and Attitudes1

Four factors (effectiveness, health risks, cost, and convenience) were orthogonally manipulated in a 3 × 2 × 2 × 2 factorial design to determine their relative importance in influencing attitudes toward and intentions to use male oral contraceptives. The experimental design also permitted a test of the assumption of additivity underlying expectancy-value models of attitude and the assumption of absence of context effects. Results were consistent with expectancy-value models of the relationship between beliefs and attitudes. In addition, it was found that health risks and effedtiveness, in that order, were the most important factors influencing receptivity to male oral contraceptives, with the effects of cost and convenience being mediated by these two factors. Sex differences in attitudes toward male oral contraceptives were also observed.     

The effect of alcohol on male aggression toward female targets

This study attempted to determine the effects of alcohol, verbal provocation, and target strategy on male aggression toward female targets. Intoxicated and nonintoxicated male research participants competed with a female confederate in a reaction time task designed to measure aggression. Intoxicated participants responded more aggressively than did nonintoxicated participants. Verbal provocation had no effect on participants' aggressive response. Effects of target strategy and trial outcome lent support to a cognitive disorganization interpretation of the effect of alcohol on aggression.     

The perceived social status of husbands and wives in dual-work families as a function of achieved and derived occupational status

The perception of the general social standing of husbands and wives in dual-work families as a function of their respective achieved and derived occupational statuses was examined experimentally. The results indicated that both the wife's and husband's general social status was a function only of the husband's occupational status; the wife's occupational status had no effect on either her general social status or that of her husband. The one exception to this was the case of the high achieved occupational status wife depressing the social status of the low occupational status husband. The results are discussed in terms of their implications for recent critiques of male-determined stratification models.     

Abstraction of contingency in concept learning

It is generally agreed that concept learning involves the abstraction of some general representation or schema. Just what is abstracted, however, and how it is used in the classification of sets of stimuli in the natural world or in the laboratory, remain outstanding questions. In this paper a hypothesis involving contingency abstraction is described as a possible solution to these questions. An experiment which manipulated measured contingency in a concept-learning task, and which offered empirical support for the hypothesis, is reported. The advantages of a contingency-abstraction theory of concept learning are briefly discussed.     

Mental imagery and pictorial memory

Previous research has failed to show consistent effects upon memory performance of individual differences in the use of mental imagery. A test of pictorial memory was devised which varied the ease with which the stimulus patterns could be verbally encoded. A factor analysis related performance in this task to a variety of other individual characteristics. The recall of material which could not be readily verbalized defined a factor within the solution which showed significant loadings of age and performance in the Progressive Matrices, but not of subjective ratings of the vividness of experienced imagery. The recall of material which could be readily verbalized did not contribute to the factorial structure of the results. It was concluded that the two sorts of pictorial material are remembered in quite different ways.     

Race,Sex, and Helping in the Marketplace1

In a field study of helping behavior carried out in 48 “convenience” grocery stores, customers tried to purchase for $1.00 a product clearly labeled as costing from $1.15 to $1.50. Amount of help by white clerks (allowing the purchase for $1.00) varied as a function of sex of customer and race of customer. Black male customers were helped least often. Neither the dress of the customers (casually-dressed or well-dressed) nor the racial makeup of the store's clientele was significantly related to helping. Implications of these findings for concepts of same-race bias and “reverse discrimination” in helping are discussed.     

Objections to personal counselling in schools

This paper seeks to identify some of the more compelling arguments put forward by those who oppose or criticise personal counselling in schools. These arguments cannot be dismissed lightly, and counsellors will have to give them serious consideration if a satisfactory resolution of the issues is to be achieved.     

A comparison of the key-peck and treadle-press operants in the pigeon: differential-reinforcement-of-low-rate schedule of reinforcement

Key pecking and treadle pressing in pigeons were compared under concurrent (key-treadle) and single-operant differential-reinforcement-of-low-rate schedules of food reinforcement ranging from 5 to 60 sec (concurrent procedure) or 5 to 120 sec (single-operant procedure). Under both procedures, the two operants followed the same general law: decreasing response rate and reinforcement rate and increasing number of responses per reinforcement as a function of increasing schedule interval. High correlations were found between key pecking and treadle pressing for the measures of response rate, reinforcement rate, and responses per reinforcement. Regression equations allowed the prediction of treadle pressing from key pecking. More bursting occurred in responding to the key, and key pecking showed a more precise temporal discrimination than treadle pressing. A test for sequential dependencies between key and treadle responses showed significant dependencies not only under the concurrent procedure but also in data created artificially by merging key and treadle sequences from different pigeons under the concurrent procedure and from the same pigeon under the single-operant procedure. It seems likely that the sequential dependencies found were due to the independent action of the schedule on each operant and that behavioral dependencies did not occur with the concurrent training procedure. The key-peck operant does not appear to have any special qualities that preclude its use in discovering general laws of behavior, at least under the differential-reinforcement-of-low-rate schedule. The usefulness of the key peck in other situations requires direct experimental study.
