Competition and cooperation between groups and between individuals

Groups and individuals were compared in two experiments. In the first, two same-sex individuals or two same-sex dyads played 10 trials of a Prisoner's Dilemma matrix game (PDG) for money. Play between individuals was more cooperative and less competitive than play between groups. In the second experiment subjects played 10 trials of either PDG or mutual-fate-control (MFC) matrices. For the MFC matrix the competitive choice, which reduces the opponent's outcomes, but has no effect on own outcomes, reflects a desire to increase one's relative advantage over the opponent. Although cooperation was greater for MFC, for both PDG and MFC matrices groups were more competitive and less cooperative than individuals. A large component of the groups-individuals effect is attributed to the greater desire of groups to “win” or avoid “losing” to the opponent, regardless of their absolute outcomes.     

Verbal and nonverbal maternal controls in hearing mother-deaf child interaction

Investigators of mother-child relations have concluded that mothers of deaf children are more controlling than mothers of hearing children. Excessive maternal control has been linked to inoptimal developmental outcomes, such as child dependence, social immaturity, and submissiveness. In the present study, the verbal and nonverbal controls employed by mothers of deaf preschoolers (3.00–6.75 years) versus mothers of hearing preschoolers (3.00–6.42 years) were evaluated. Subjects were 14 hearing mother-deaf child dyads and 14 hearing mother-hearing child dyads. Each dyad was observed during a 15-minute free-play period and during a 7-minute teaching period. Dependent measures were submitted to appropriate 2 (hearing status) by 2 (task) analysis of variance for repeated measures, followed by post hoc comparisons. The results indicated that the mothers of deaf children: (a) used higher rates of nonverbal controls than the mothers of hearing children, especially during the free-play period; and (b) employed higher rates of verbal controls than the mothers of hearing children during the free-play period, but not during the teaching period. In addition, the interaction tasks exerted differential effects on the two groups of mother-child dyads.     

Effects of the recipient's status and responsiveness on physical pleasuring between heterosexual strangers

Previous research relating status to intimate behavior has demonstrated that persons are more reluctant to initiate physical intimacy with another of higher than one of equal or lower status. The present research explored three potential interpretations of the observed relationship: (1) that persons perceive others of higher status as less likely to react positively to intimate behavior, (2) that social norms discourage intimate behavior toward higher status others, and (3) that persons of different status may be differentially liked. Using a modification of the apparatus developed by Davis, Rainey, and Brock, seventy-seven undergraduate subjects chose to give either a verbal or physically pleasurable reward for correct responses to a confederate learner whom they believed to be of either higher (PhD candidate), equal (freshman), or lower (high school drop-out) academic status. The learner was either responsive to the physical reward (expressing enjoyment) or unresponsive (remaining silent). In support of the first interpretation, status affected the magnitude of physical reward only when the recipient remained silent. When clear evidence of positive reaction to the vibrations was provided by the recipient's responsiveness, status differences were eliminated. This indicates that status may be used as a basis for regulating intimate behavior only when direct information about the recipient's reactions is unclear or unavailable. The differential liking interpretation received no support, in that status affected neither rated liking of the recipient nor the magnitude of verbal reward.     

Behavioral similarity,confederate strategy,and sex composition of dyad as determinants of interpersonal judgments and behavior in the prisoner's dilemma game

The study was designed to test three distinct theoretical models relating player's attitudes toward a confederate in the prisoner's dilemma game: a reinforcing outcome model, a cultural norm model, and a social comparison model. A secondary concern of the study was to determine if player's sex, confederate's sex, and the confederate's strategy interactively influence player's choice behavior. Forty-eight male and forty-eight female subjects played 100 trials of the prisoner's dilemma game with a confederate who played either a 74% cooperative or 74% competitive predetermined strategy and then filled out the Interpersonal Judgment Scale rating the confederate. Behaviorally similar confederates received more positive evaluations than dissimilar confederates supporting the social comparison hypothesis. Further, the strategy of the confederate did not influence choice behavior in mixed-sex dyads, suggesting that sex roles may inhibit behaviorally based male-female interaction. The generality of previous gaming research which has dealt almost exclusively with same-sex dyads is called into question.     

College major and career choice: A retest of Holland's theory

In an effort to examine whether the previously established relationship between vocational choice and self-ratings on Holland's personality stereotypes among college freshmen would be strengthened with a sample of male college seniors, 109 subjects, sampled on the basis of major field choice, completed a questionnaire to select career stereotypes which described them best. The relationship between self-ratings and academic major was also to be examined. Significant relationships were obtained for four stereotypes (realistic, conventional, enterprising, and artistic) on the basis of both major and vocational choice, although significant stereotypes were not identical in each. Three of these significant relationships based on vocational choice matched those obtained previously. An additional finding suggested that vocational choice was slightly more valid than major field as a basis for utilizing this technique. The more restricted class sample emphasized did not, however, produce a more substantial relationship between self-ratings and occupational choice as expected.     

Differentiation of occupational perceptions among different age groups

The perception of occupations plays a key role in many vocational behaviors and in theories of vocational development. This study hypothesizes that occupational perceptions are more specific for older age groups than for younger age groups.This hypothesis was tested by using latent root analysis and minimum residual factor analysis to analyze the intercorrelations among six Vocational Preference Inventory (VPI) scales for five large and diverse samples-elementary school students, rural high school seniors, college freshmen, employed salesmen, and employed women.Both analyses supported the hypothesis. The results are discussed in relation to those of Cureton (1970) and the implication is drawn that occupational perceptions may be used to estimate a person's level of vocational development.     

Developmental changes in the semantic processing of pictures and words

Second- and fifth-graders' semantic decision times for pictures and words were analyzed relative to the predictions derived from unitary- and dual-memory models. At both grade levels, word-word response latencies were greater than picture-word latencies which, in turn, were greater than picture-picture latencies. An interaction between Grade and Condition indicated that verbal access times decreased more than pictorial access times. The data fit the predictions of a memory model postulating category storage in a single memory system as opposed to simultaneous representation in verbal and nonverbal memory systems. It was concluded that with increasing experience verbal access to this single semantic system is more rapid.     

Some analyses of the verbal encoding deficit of alcoholic Korsakoff patients

Two experiments were designed to assess Korsakoff patients' ability to encode verbal information on the basis of its physical, nominal and semantic properties. The first investigation employed Wickens' release from proactive interference (PI) technique; a procedure that allows an assessment of a subject's ability to encode verbal information on the basis of its semantic properties. It was discovered that on tasks involving only a rudimentary verbal analysis, such as the ability to discriminate letters from numbers, the Korsakoff patients demonstrated a normal release from PI. However, on tasks that required a more sophisticated level of semantic encoding, such as those based on taxonomic class inclusion, the patients failed to show release from PI. The second investigation employed Posner's reaction time technique which assesses a subject's ability to encode the physical and nominal properties of simple verbal materials (letters). The results of this study showed that Korsakoff patients are impaired on even these rudimentary encoding tasks, which led to the proposal that Korsakoff patients' semantic encoding deficit might stem from an initial impairment in the speed at which physical and nominal properties of verbal information are analyzed.     

Word production and comprehension in Alzheimer's diseáse: The breakdown of semantic knowledge

Relatively mildly impaired patients with suspected Alzheimer's disease (N = 14; Verbal IQ = 96) and normal controls of similar age and education (N = 11) were administered tests requiring production (naming and fluency) and comprehension of single words. Word comprehension was assessed on a superordinate level (rating words for degree of “pleasantness”) and on a more specific level (matching abstract pictorial representations with printed words denoting objects, actions, emotions, and modifiers). Performance on standardized measures of semantic knowledge (Vocabulary and Similarities subtests of the WAIS) was also evaluated. The naming and fluency abilities of the Alzheimer's patients were found to be highly correlated (r = .80) and impaired. Naming errors often consisted of semantic field errors which were either hierarchically or linearly related to the target name. In comparison with normals, verbal fluency was characterized by a tendency to generate proportionally more category names concurrent with reduced production of items within a category. Single-word comprehension was also impaired, except when judgments of affective meaning were required. It was argued that these results suggest that Alzheimer's disease may lead to a specific disruption in semantic knowledge characterized by a difficulty in differentiating between items within the same semantic category concurrent with the relative preservation of broader categorical information.     

Father identification,achievement, and occupational behavior of rural youth: 10-year follow-up

Males from rural economically deprived school districts, who had previously been surveyed as high school seniors, again 1 year after graduation, and again 5 years after graduation, were surveyed a fourth and final time 10 years after high school graduation concerning their occupational status and aspirations, their marital status, their spouses' educational and occupational achievements, the importance of life roles, and their occupational and personal satisfactions. In the original study the participants had been divided into two groups, low-identification males (LIM) and high-identification males (HIM) based on independent evaluators' judgments of the adequacy of their fathers as identification models. Each group's responses to the survey were compared. The results indicate that there were no statistically significant differences between the two groups on the variables of optimism about the future, spouses' occupational achievements, role importance, occupational satisfaction, and personal satisfaction. There were statistically significant differences on the variables of occupational status, occupational aspirations, educational achievements, educational plans, marital status, and spouses' educational achievements. The results are discussed in the context of the three previous surveys. Over the 10-year period the occupational and educational achievements and aspirations have been significantly higher for the HIM group than for the LIM group. Equally consistent is the finding that over the 10-year period there has been no differences between the two groups in satisfaction with status.     

Relations of socioeconomic status and sex variables to the complexity of worker functions in the occupational choices of elementary school children

The relationships of sex and socioeconomic status to complexity of worker functions in the occupational choices of elementary school children were studied. Complexity of worker functions was defined in terms of the most complex level of interaction required of a worker, when interacting with data, people, and things. The children included in the study were third- and fifth-grade students, divided on the basis of grade, sex, and socioeconomic status. The children's occupational choices were scored for complexity with the code numbers of the worker function hierarchies of the U.S. Employment Service's Dictionary of Occupational Titles (Washington, D.C.: U.S. Govt. Printing Office, 1977, 4th ed.). Findings based on the obtained data indicated the following: (a) a positive relationship between socioeconomic status and complexity of data manipulation in occupational choices; and (b) greater complexity of interaction with things in the occupational choices of boys, than girls. The positive relationship between socioeconomic status and complexity of data manipulation was accounted for by the children's exposure to their parents' orientation toward data manipulation. Apparent differences in the play activities of boys and girls was used to explain differences between the sexes in the levels of complexity of interactions with inanimate objects and animals.     

Knowing when you don't know enough: Children's judgements about ambiguous information

Two experiments were carried out to find out whether young children's failure to realise when messages are ambiguous is specific to verbally transmitted information about a person's intended meaning. In Experiment 1, children judged whether they had been told/shown enough to identify which one of a set of cards the experimenter had chosen. In one game the experimenter gave verbal messages about her chosen cards, and in a second game, she gave visual messages. With ambiguous visual messages, relevant parts of cards were physically covered. We expected that this would make it more obvious that the speaker's intended meaning was not being fully conveyed. No difference was found between verbal and visual conditions: correct judgements about message ambiguity occured with the same frequency in both.In Experiment 2, children judged in one game whether they had been told enough about the experimenter's chosen card, as in Experiment 1. In a second game, visual information about a card was not conveyed by the experimenter, Rather, the child operated a pointer, set in a disc with windows, beneath which lay cards. The child judged whether the window showed enough for him/her to tell which card the pointer indicated. Again, correct judgments about ambiguity occured with the same frequency in both games.The results implied that children's failure to realise when verbal messages are ambiguous is but one aspect of a more general failure to realise when one has insufficient information at one's disposal to guarantee a correct interpretation of what the world is like.     

Managerial aspirations of high school seniors: A comparison of males and females

Empirical research in the past has indicated that young people are generally not oriented toward managerial careers and that females are less so than are males. However, the greater career orientation of today's students, recent changes in societal values, persistent attempts by women to obtain equality, and federal legislation expressly forbidding discrimination may have changed this situation by the late 1970s. A survey of 2112 high school seniors in the state of Alabama was conducted to investigate these issues. Results indicate that few high school seniors aspire to management careers and that sex continues to be a major discriminator. The “male managerial model” continues to be reinforced by the values and attitudes of society as reflected in its young people.     

Students' perceptions of male sexually aggressive behavior as a function of educational level and gender

Two hundred and four students (108 college freshmen, sophomores, juniors, and seniors; 96 high school juniors and seniors) participated in this study. The socioeconomic status of the participants (high school = 93% Caucasian, 7% African-American; college = 96% Caucasian, 4% African-American) was primarily in the lower middle-class range. The purposes of this investigation were (1) to test whether or not differences exist between high school and college students' perceptions of one form of male sexually aggressive behavior against women, (2) to determine if differences exist between male and female students' perceptions of such behavior against women, and (3) to explore the sex role socialization theory by providing empirical observation of its basic tenets. Findings suggested that boys may experience slower maturation and development of sensitivity toward sexual aggression than girls, but that this gap may lessen with advancing age for college males.     

Reference group perspectives and the vocational maturity of lower socioeconomic black youth

The reference group perspectives of 188 lower socioeconomic black high school seniors were found to be related to their career maturity. Students who evidenced an orientation toward middle-class reference group perspectives obtained higher vocational maturity scores than those who subscribed to reference perspectives traditionally associated with the lower class. Students' sex and family background were not related to their reference group perspectives or to their vocational maturity ratings. It was found that students' post-high school plans (either work- or college-bound) and their views of the opportunity structure of America were related to both their reference group perspectives orientation and their career maturity scores. Questions are raised concerning the relevance of the term career maturity for analyzing the career development of lower socioeconomic black youth.     

Father identification,achievement, and occupational behavior of rural youth: One year follow-up

Rural economically deprived adolescent males, who had been previously surveyed as high school seniors concerning their post-high school plans, were surveyed again 1 yr later concerning their present occupational status and feelings of personal satisfaction. The Ss had been divided in an earlier study into two groups, low identification males (LIM) and high identification males (HIM) based upon independent evaluators' judgments of the adequacy of their fathers as identification models. Each group's responses to the survey were compared. The results indicate that there are no statistically significant differences between the two groups on the variables of satisfaction, having received counseling from others and optimism about the future. There are statistically significant differences between the current occupational status and future occupational plans of the two groups.     

Intellectual development and its relationship to maturation during the college years

This study examines whether differences in the development of critical reasoning abilities among undergraduates can be attributed to factors other than college attendance, and specifically to differences in chronological maturation. Eight males and eight females were randomly selected and matched on ACT composite scores from each of four groups: 18-year-old freshmen; 22-year-old freshmen; 22-year-old seniors; and 26-year-old seniors. Theses 64 subjects were arranged within a non-assignable three factor design by age (adult and traditional), class level (freshman and senior), and sex. Subjects were administered the Reflective Judgment Interview, a structured interview format designed to measure the way individuals reason about intellectual problems. Two significant main effects were observed, with seniors scoring higher than freshman (p < .001), and males scoring higher than females. The class level main effect, in the absence of any significant difference of reflective judgment level due to age, suggests that college attendance does contribute to the development of critical reasoning beyond the factor of chronological maturation. An explanation for significant sex differences found is not clearly discernible from these data.     

Modification of cooperation and aggression through teacher attention to children's speech

Two experiments were performed in the naturalistic setting of a preschool classroom in order to assess the effects on children's social behavior of nonevaluative teacher attention to children's cooperative or aggressive speech. In Experiment 1, teachers attended to the children's spontaneous cooperative speech for two weeks. Observation of the children's free-play behaviors revealed an increase over baseline levels in both verbal and physical cooperative behaviors as well as a decrease in both verbal and physical aggressive behaviors. In Experiment 2, teachers attended first to the children's spontaneous aggressive speech for one week and then switched their attention to the children's cooperative speech for a second week. Teacher attention to aggressive speech in the first week led to an increase over baseline levels in the children's verbal aggressive behavior as well as a decrease in both verbal and physical cooperative behaviors; however, physical aggression remained unchanged. Teacher attention to cooperative speech in the following week served to reverse the effects of the first week's treatment. The findings were discussed in terms of the sequential relationship between verbal and nonverbal components of cooperative and aggressive social behaviors and the teacher's role in modifying children's performance on these behaviors in the classroom.     

TO NOD OR NOT TO NOD: AN OBSERVATIONAL STUDY OF NONVERBAL COMMUNICATION AND STATUS IN FEMALE AND MALE COLLEGE STUDENTS

Gender studies show that women and men communicate using different styles, but may use either gender style if there are situational status differences. Considering the universal gesture of head nodding as a submissive form of expression, this study investigated head nodding by observing female and male college students in positions of subordinate and equal status. We observed head nodding ( N = 452) in classroom interactions between professor–student and student–student dyads. Overall, women nodded more than men and students nodded more to professors speaking than peers speaking. In addition, female and male students nodded equally to professors speaking, but men nodded less to peers speaking than did women. Thus, both men and women attended to the status and not the gender of the speaker. Future research using varying contexts should further examine the effects of dominance, context, and gender.
