The effects of social reinforcement and task difficulty level on the pleasure derived by normal and retarded children from cognitive challenge and mastery

In order to examine several factors influencing the pleasure derived from mastery, 32 normal first-grade children (mean MA = 7.7) and 32 MA-matched familial mentally retarded children were given puzzles representing four difficulty levels. Half of the children were socially reinforced for their successes and half performed in an experimenter-absent condition. There was more smiling among normal than retarded children, in the social reinforcement than in the experimenter-absent condition, and among girls than boys. The condition effect was greater for girls than boys. In the experimenter-absent condition, normal children displayed more pleasure on the difficult than on the easy puzzles, whereas the trend was just the reverse for the retarded children. Large within-sex differences were found for normal girls only, revealing that one subgroup derived more pleasure from the more difficult puzzles whereas another subgroup enjoyed the easier puzzles more. The findings were discussed in terms of the author's refinement of White's model of effectance motivation.     

The effect of monetary incentives on backward digit span performance

In order to determine if monetary-incentive effects, particularly the detrimental effects of such incentives on human learning and performance, might be mediated by anxiety, 52 college students were administered six backward digit trials in a preexperimental, baseline phase and six trials in an experimental, test phase. Of the 52 subjects, 26 were paid 50 cents following each correct recitation of a backward digit series during the test phase. The remaining 26 were unpaid control subjects. Results showed that the rationale for the study was correct because state anxiety was indeed negatively related to backward digit span performance as previous research had shown, but the offer of reward did not elevate state anxiety scores and, more importantly, the offer of reward led to a significant improvement in backward digit span performance—an effect which is the opposite of what would be predicted by the anxiety hypothesis. The reward effects of theoretical interest in planning this research were those facilitating and detrimental effects that are produced by offering elementary, high school, or college students small amounts of money (typically from $1 to $3) as a superfluous inducement to participate in a study of human learning or performance. The results of this study discredit any explanation of such reward effects which attributes the effects to reward-induced anxiety.     

Monaural right-ear advantage in a target-identification task

Subjects were monaurally presented with consonant—vowel syllables to the right or left ear, with or without simultaneous noise to the other ear. The subject's task on each trial was to indicate whether or not the item presented was the target item /ba/. A right-ear advantage in reaction time was obtained: 14 msec for target items, 6 msec for nontarget items. The size of this effect was comparable in the presence vs. absence of competing noise. No consistent individual differences were found in the size of the right-ear advantage for this task, although such differences were obtained in a dichotic-perception pretest.It is argued that data of this type do not permit inferences about the use of particular ear/hemisphere neural pathways.     

The effects of consensus requirements and multiple decisions on mock juror verdict preferences

After watching a simulated rape trial, prerecorded on videotape, mock jurors either did or did not expect to sentence a defendant following deliberation with or without a group verdict required. Both sentencing expectation and verdict requirement significantly elevated jurors' preference for conviction (and average ratings of guilt likelihood). Closer analyses of personal changes (before and after deliberation) in the distribution of opinions suggested that majorities favoring not guilty were more influential than guilty-favoring majorities; and, somewhat unexpectedly, minorities in juries which deliberated without a verdict required were more likely to change personal opinions than minorities in juries required to render a verdict. The overall social decision scheme confirmed earlier observations about the importance of the initial majority in determining the verdict; but the majority did not always prevail and there was a marked asymmetry (“defendant protection”) in its action.     

Interactive effects of generalized and situational expectancies on the arousal of cognitive and emotional components of social anxiety

This study examined the arousal of social anxiety in an interview setting as a function of anticipated self-disclosure. Of 88 college students who completed the Social Avoidance and Distress (SAD) scale and other measures of social anxiety, self-disclosure, need to affiliate, and interpersonal trust, 24 volunteered for the interview. During the interview, both components of anxiety (worry and emotionality) were affected by expectancy conditions, and emotionality was higher for high- than for low-SAD subjects. The prediction of an interaction between SAD level and expectancy condition on worry was confirmed: only high-SAD subjects exposed to the negative-expectancy condition experienced significant elevations in worry. Though social anxiety and self-disclosure measures correlated negatively, anxiety did not affect self-disclosure during the interview.     

The effect of set size on hemifield asymmetries in letter recognition

Single letters were presented tachistoscopically in the left or right hemifield to right-handed observers. Superior recognition of letters on the right was found for letters chosen from subsets containing four items, but no differences were found when any letter, or any symmetrical letter, could appear. In a second experiment, the right hemifield advantage was found under conditions requiring the subject to determine the subset only when the subset chosen was appropriate. Results were discussed in terms of the adequacy of language-based explanations of hemifield asymmetries in letter recognition.     

Bilateral tachistoscopic perception,handedness, and laterality: II. Nonverbal stimuli

Thirty-two Subjects were assigned to four groups on the basis of handedness (left or right) and familial sinistrality (absent or present). Their laterality patterns were investigated with a cued order-of-report paradigm. On each trial, Subjects saw a tachistoscopic presentation of two outline drawings of common objects, one drawing on the left of a central fixation point, one on the right. A centered arrowhead appeared with the pictures; the arrowhead pointed either left or right, and its direction indicated the order of report. The results for each group were discussed in terms of asymmetry for rate of processing and rate of decay, and in comparison with our earlier study of word recognition.     

Lateralization effects in the perception of Hebrew and English words

A series of four experiments was conducted on Israelis with a good knowledge of English, Anglo-Saxons with a good knowledge of Hebrew, and full Bilinguals of the two languages. In all experiments words were presented vertically and measurements of both accuracy and response times were taken. Experiments 1 and 2 examined the perception of Hebrew words in unilateral and bilateral conditions, respectively; Experiments 3 and 4 examined the perception of both Hebrew and English words in these two conditions. The results revealed right visual field advantage in the perception of words in both languages and in all groups. A reversal between the two conditions was not found. The data support the hypothesis whereby nonnative languages are less lateralized than native ones, but they indicate that full bilinguals are more, not less, lateralized than monolinguals. Various hypothesis regarding the relationship between lateralization and bilingualism are discussed.     

The perception of alternated speech

When speech is rapidly alternated between the two ears, intelligibility declines as rates approach 3–5 switching cycles/sec and then paradoxically returns to a good level beyond that point. The present study examines previous explanations of the phenomenon by comparing intelligibility of alternated speech with that for presentation of an interrupted message to a single ear. Results favor one of two possible explanations, and a theoretical model to account for the effect is proposed.     

Criterion-related and construct validity of the Career Maturity Inventory Competence Test with ninth-grade pupils

The purpose of this study was to examine the criterion-related and construct validity of the Career Maturity Inventory Competence Test. The Competence Test, Attitude Scale, and Cognitive Vocational Maturity Test were administered to 260 ninth-grade pupils in a rural junior high school to determine whether the variables were interrelated as hypothesized in theCrites (Theory and research handbook for the Career Maturity Inventory. Monterey, Calif.: CTB/McGraw-Hill, 1973) model of career maturity. The results show that, as predicted, the Competence Test is more highly correlated with the Cognitive Vocational Maturity Test than it is with the Attitude Scale. Also, as predicted, the subscales of the Competence Test are intercorrelated between .40 and .69. However, the correlations of the Attitude Scale with the Competence Test total score and the Cognitive Vocational Maturity Test total score are higher than the theoretical expectation.     

An investigation of repetition and language processing in a case of conduction aphasia

A study is reported of a single case of conduction aphasia. A battery of tasks designed to investigate the parameters of the patient's severe repetition deficit is supplemented by tests of several language functions. The results provide extensive information on a wide range of the patient's language abilities and are used to evaluate the adequacy of four models that have been offered to account for conduction aphasia. An argument is made in support of the suggestion that the syndrome of conduction aphasia should be divided into two subgroups based on patients' ability to select and realize phonemes in speech output. It is concluded that the best explanation for the disorder of patients with repetition deficit but without significant speech output problems is the hypothesis that repetition ability is compromised by a pathological limitation of auditory-verbal short-term memory. This hypothesis is extended to account for the pattern of results obtained in the language tasks.     

Interaction of reinforcement conditions and developmental level in a two-choice discrimination task with children

A total of 540 first, fourth, and eighth graders, equally divided by sex, were run on a two-choice discrimination task under one of three reinforcement conditions: reward (R) for correct responses, punishment (P) for incorrect responses, or reward and punishment (RP) for correct and incorrect responses. Half the Ss were tested by a male E; half, by a female E. Across all developmental levels, learning was superior in the P group. Complex interactions involving sex of S and E underline the importance of organismic variables in discrimination learning and in specifying parameters of reinforcer effectiveness.     

Being imitated, conformity, and social influence: An integrative review

The recently developed literature on the effects of being imitated and the social influence function of imitation are reviewed, as is related literature on conformity from social psychology. Then, this research is considered within a number of theoretical contexts, but especially within the conceptual framework of Byrne's elaboration of effectance motivation. Finally, questions are raised which need to be addressed in future research.     

Relationships between locus of control,health value,and preventive health behaviors among women

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended.     

Short-term memory performance in the absence of phonological coding

These experiments examined the short-term memory performance of an aphasic patient with posterior damage who shows a selective deficit in phonological coding. In recognition memory tests, the patient relied on both visual and semantic coding, and often showed an essentially normal level of accuracy. However, for memory sets consisting of four function words, his performance was quite impaired. Also, his retention of order information was far below that of normal controls. The implications of these deficits in short-term memory for language comprehension and production are discussed.     

Acquisition and transfer of conceptual learning by normals and retardates: the effects of modeling, verbal cues, and reinforcement

The present study compared the effects of modeling, verbal cues, and reinforcement on conceptual learning of normals and retardates. Performance on both original learning tasks and a transfer task was examined. The results indicated that, relative to a control group, modeling alone, modeling plus verbal cues, and exposure to the completed task plus verbal cues facilitated original conceptual learning. Furthermore, modeling plus verbal cues was more effective in reducing errors than modeling alone. Original learning was not affected by tangible reinforcement, social reinforcement, or IQ level. No significant effects were found for a transfer task.     

Antecedents of educational/career preferences and choices

The primary purpose of this study was to investigate the influence of social reinforcement, modeling, direct reinforcement, and words and images on the acquisition of career-related preferences. The study also examined the mediating role of career decision-making skills (CDMS) on the factors influencing preference. Finally, the combined influence of career-related preferences and CDMS on certainty about career choices was investigated. A total of 47 college students completed a questionnaire describing antecedent factors influencing their preference for a major or a career and evaluating the degree of influence of each factor. Students' scores on a vocational maturity inventory were the basis for dividing them in high and low groups. Students identified social reinforcement as the most important antecedent for their career preference. Results indicated that CDMS mediate the influence of models and direct reinforcement on career preference. Career-related preference was a better predictor of career certainty among low than high maturity students. Findings support and extend a social learning theory of career development.     

The causal structure of situations: The generation of plausible causal attributions as a function of type of event situation

The causal structures for each of four types of situations—interpersonal failure, noninterpersonal failure, interpersonal success, and noninterpersonal success—were explored and compared. A first group of subjects generated plausible causes for five specific situations in each of the four general types of situations. A second group of subjects provided similarity data on these causes, which were used in a cluster analysis of the causes. A third group of subjects rated the generated causes on each of six dimensions reported in the attribution literature: changeability, locus, stability, intentionality, globality, and controllability. Analyses of the clusters of causes and the ratings revealed (a) different types of causes were generated for different types of situations, (b) different types of situations led people to generate causes that differ in dimensional location, (c) the various causal dimensions were highly intercorrelated. These findings were applied to A. W. Kruglanski's (Psychological Review, 1980, 87) model of attribution processes. In addition, implications for the study of interpersonal situations and for the cognition-motivation debate over “self-serving” bias in attribution were discussed. Finally, several methodological issues were examined.     

Studies toward a model of laterality effects for picture and word naming

Experiments requiring the naming of bilaterally presented nouns, picturable nouns, consonant-vowel-consonant (CVC) nonwords, and line drawings are reported. In order to eliminate order of report strategies and facilitate comparison across experiments, the stimulus to be reported first was cued by underlining at presentation of each trial. Large right visual hemifield (RVF) superiorities were found to arise from both first and second reports for naming nouns and CVC nonwords. Drawings and picturable nouns, however, produced only a small RVF superiority arising entirely from subjects' second reports. It is proposed that hemispheric laterality effects for naming visually presented stimuli can arise from three principal sources, and the application of this model to existing studies is outlined.     

Differential relationships of extraversion,impulsivity, and sociability to study habits

Reanalysis of data on library study habits presented by J. B. Campbell and C. W. Hawley (Journal of Research in Personality, 1982, 16, 139–148) revealed differential utility for the EPI extraversion scale and its components, impulsivity and sociability. Individuals studying in locations that provided greater external stimulation had significantly higher extraversion and impulsivity, but not sociability, scores than individuals studying elsewhere in the library. Impulsivity was more strongly associated than sociability with preferred noise levels, frequency of study breaks, and importance and preferred levels of socializing opportunities, but less strongly associated with preferred levels of crowdedness. Findings are discussed in terms of the interpretation, reliabilities, and theoretical context of the subscales.
