Reactions to success and failure in public and in private conditions

It was shown that the reaction to success and failure differs when it is communicated publicly or privately and when the reaction to success and failure is measured publicly or privately. Participants took an intelligence test and received fictitious results which were positively or negatively discrepant from the average. The dependent variable was the evaluation of the intelligence test. It was found that when the subject's evaluation of the test was private, the test was evaluated more positively under public than under private success. However, it was evaluated more negatively under public than under private failure. Under public success feedback the test was evaluated more positively under private than under public evaluation, whereas under public failure feedback the effect was reversed. The results are interpreted in terms of a self-presentation model and were discussed in the context of earlier research within the field of interpersonal relations.     

FINDERS,KEEPERS?: AN ANALYSIS AND VALIDATION OF A FREE-FOUND-AD POLICY

A SURVEY OF LOST AND FOUND CLASSIFIED SECTIONS IN METROPOLITAN AND SMALLER NEWSPAPERS REVEALED DISPARATE RATES BETWEEN LOST ADS AND FOUND ADS: Lost ads greatly outnumbered Found ads, probably because newspapers usually require the finders of lost personal property to pay for Found advertisements. The effect of a Free-Found-Ad policy on the rate of Found advertisements placed in the Lost and Found sections of three community newspapers was investigated using a multiple-baseline design. The results suggested that the Free-Found-Ad policy was effective in increasing the rates of Found ads in all three newspapers. To determine whether increases in Found ads resulted in increases in recovered property, a sample of individuals who placed Found ads were surveyed in both baseline and treatment conditions and asked if the found items had been claimed by their owners. The Free-Found-Ad policy appeared to be effective in increasing the amount of personal property returned. The study concluded that community newspapers can provide incentives to increase such help-giving or altruistic behaviors. The implications of this study for a general policy-research strategy are discussed.     

The role of short-term working memory in mental arithmetic

A series of experiments explored the role of information storage in working memory in performing mental arithmetic. Experiment 1 assessed the strategies people report for solving auditorily presented multidigit problems such as 325 + 46. As expected, all subjects reported breaking down the problems into a series of elementary stages, though there were considerable individual differences with regard to the order of their execution. Strategies of this type necessitate both the temporary storage of information and the mobilization of long-term knowledge. Experiments 2 and 3 examined the effects of delaying the output of individual partial results on calculation accuracy and showed that interim information is forgotten if it is not utilized immediately. Experiment 4 showed that forgetting the initial information is also a source of error and suggested that forgetting increases as a function of the number of calculation stages intervening between initial presentation and subsequent utilization of information. Two simple quantitative models were derived from a general task analysis, one of which assumed a decay process in working storage and the other no decay. The decay model gave a reasonable fit to data from Experiments 2–4, and in doing so it coped appreciably well with the effects of a large variety of task variables (e.g., carrying, the provision of written notes, calculation strategy, output order). The decay model is a tractable analysis of a complex task, and it is suggested that similar analyses may prove fruitful for other problem-solving activities which involve the use of working memory.     

The recovery processes of two English-Japanese bilingual aphasics

The recovery processes of two English-Japanese bilingual aphasics, one with Broca's aphasia and the other with Wernicke's aphasia, were investigated with special emphasis on the effect of language therapy. The degree of impairment initially manifested in English and Japanese was almost equivalent in each case, the pattern of impairment corresponding to the respective types of aphasia. In both cases, systematic, controlled language therapy was conducted. Analysis of the recovery courses revealed that language therapy was one decisive variable in the relative degree of recovery of a bilingual aphasic's two languages. The type of aphasia appeared to exert a crucial influence on the relative recovery rate of different modalities.     

The word order problem in agrammatism : I. Comprehension

The results of a picture-pointing comprehension test show that agrammatic aphasics have difficulty understanding sentences in which the underlying semantic roles are marked by the order of noun phrases around a verbal element. Agrammatic patients performed poorly on reversible constructions involving spatial prepositions (e.g., “The square is above the circle”) and verbs (e.g., “The dancer applauds the clown”). These results have significance for the interpretation of the underlying disturbance in agrammatism—whether the deficit is syntactic or purely phonological.     

Testing hypotheses regarding rape: Exposure to sexual violence,sex differences,and the “normality” of rapists

Three hypotheses on the subject of rape were addressed empirically. The first concerns the effects of exposure to sexual violence on reactions to rape. Males and females were first exposed to either a sadomasochistic or a nonviolent version of the same sexual passage and then to a portrayal of rape. Responses to the rape showed interactions between gender and previous exposure: In comparison to males who had read the nonviolent version, males exposed to the sadomasochistic story were more sexually aroused to the rape depiction and more punitive toward the rapist whereas females evidenced differences in the opposite direction. Simple effects analyses for each gender, however, yielded significant differences for the punitiveness measure only and for males only. In addressing the second hypothesis, gender differences were found in the perception of rape. Third, the assertion that rape may be an extension of normal sexual patterns was explored. Subjects were found to believe that a high percentage of men would rape if assured of not being punished and that a substantial percentage of women would enjoy being victimized. While both genders shared these beliefs, very few women believed that they personally would derive pleasure from victimization. Surprisingly, more than half of the males indicated some likelihood that they themselves would rape if assured of not being punished. The association between this self-report and general attitudes toward rape revealed a pattern that bears striking similarity to the callous attitudes often held by convicted rapists.     

Three experiences affecting spatial discrimination learning by ambulatory children

Children 1 and 3 years of age were given a two-choice spatial discrimination task. They were placed in front of a barrier and encouraged to walk around it; one route around the barrier was blocked. Three experiments studied the effects of different types of experience with this spatial problem. The first examined trial and error experience, in which the child was allowed to walk the route he or she had chosen. Although most children readily learned to choose the open route, the pattern of choices indicated that 3-year-olds were more likely to achieve a learning criterion after an error than 1-year-olds. A second experiment looked at the effects of showing the children the layout of the problem prior to trial and error experience. The 3-year-olds were again more likely than the 1-year-olds to achieve criterion after an error; furthermore, they were likely to know the correct route on the first trial. The third experiment let the children watch their parents take the correct route. This procedure eliminated age differences in performance. The initial choices of the 1-year-olds indicated that they were likely to know the correct route, and if they did not, they were just as likely to learn from their mistakes as the 3-year-olds. The data were interpreted within a mathematical model of learning. Based upon these analyses, we propose two developmental trends. One involves a growth in sensitivity to the consequences of a choice of route. The other is a progression from social learning to more independent and ideational methods of spatial problem solving.     

Stimulus control of defensive burying in the rat

Rats shocked once through a wire-wrapped stationary prod mounted on the wall of a test chamber incorporated the bedding material covering the chamber floor into a defensive reaction. When tested 1 min later, they approached the prod and buried it. Evidence was provided by three separate studies of this burying response that rats had learned about the association of both the position and brightness of the prod with shock after this single conditioning trial. In Experiment 1, the amount of burying decreased if either the position or brightness of the prod had been changed prior to the test. In Experiments 2 and 3, rats were shocked through one of two prods (white or black) mounted on opposite walls of the test chamber. When the positions of the prods were unchanged for the test, almost every subject buried the prod through which it had been shocked, even when the conditioning-test interval was 24 hr; whereas, each rat directed substantial amounts of bedding material at both prods when the positions of the two prods were reversed. Thus, discriminated “avoidance” learning can be rapid, reliable, and enduring when shock is administered “by” a clearly defined stimulus object, i.e., when cue and consequence are spatially contiguous.     

Sequences of phonemic approximations in aphasia

The trends of sequences of phonemic approximations to a single target were studied in three types of aphasia (Broca's, conduction, and Wernicke's), as gathered in five tasks (spontaneous speech, repetition of meaningful words, repetition of nonsense words, reading aloud, and automatized sequences). A phonemic error ratio was defined in order to quantify the distance between each approximation of a given sequence and its target. The results of a computer analysis based on this ratio were analyzed according to three parameters. A study of three types of patients revealed that conduction aphasics exhibited the most regular trend toward the target in sequences of phonemic approximations; the analysis of the various tasks indicated that sequences produced in repetition by conduction aphasics form an exception to the regularity of this trend, and an examination of the various lengths of sequences indicated that longer sequences showed a less decisive trend toward the target than shorter sequences. The discussion bears on some theoretical aspects of the phonological production mechanism and its control: the initial strength and permanence of the internal representation of the target emerge as important factors required for the good functioning of this mechanism.
