On the mutual influence of individuals in a social group

A previous mathematical study of a situation, in which the behavior of a larger group of individuals is controlled by a smaller group, is generalized for the case when the activity of the individuals in the group is continuously graded. The existence of two possible social configurations and of sudden transitions from one configuration to another are found in this case also.     

The school psychologist as a source of power and influence

This essay reviews the historical role of the school psychologist and examines his impact on educational systems. Past influences of the school psychologist in effecting understanding and acceptance of individual differences of children are examined in relationship to the contemporary need to relate this knowledge to appropriate educational planning for a culturally diverse school population.     

Experimental design as a source of sex bias in social psychology

In order to determine whether there is evidence for sex bias in experimental design, abstracts of 312 experiments on interpersonal attraction and 244 experiments on aggression which used only male or only female subjects were coded according to types of variables studied. Results indicate that when females are subjects in experiments the independent variable manipulation is less likely to involve the active treatment or arousal of the subject and the dependent variable measurement is less likely to involve the active behavior of the subject, than when male subjects are used. These findings are discussed in terms of their implications for how sex differences should be studied.Portions of this article were presented at the meeting of the American Psychological Association, New Orleans, September 1974. The authors would like to thank Howard Ehrlichman for his valuable comments.     

The effects of social context,source fairness,and perceived self‐source similarity on social influence: a self‐categorisation analysis

Based upon a self‐categorisation analysis of social influence (Turner, 1991), we predicted that individuals who self‐categorise with the source of a communication would align their own private attitudes more closely with the source when that source was distributively fair rather than unfair in an intragroup context. We expected this pattern to reverse in an intergroup context when the unfairness was ingroup favouring. These expectations were confirmed in a laboratory experiment (N=101). The data suggest that neither source similarity nor source fairness serve simply as persuasion cues to which individuals thoughtlessly conform. We argue, instead that, once self‐categorised, individuals: (1) actively attend to an ingroup member's behaviours and the context in which they occur, and (2) are influenced only by a source who provides some form of social identity enhancement, either by being fair in an intragroup context (Lind & Tyler, 1988) or ingroup favouring in an intergroup context (Tajfel & Turner, 1986).

Group composition as a determinant of Kelman's social influence modes

It is argued that compliance in groups will be highest where the composition is maximally confrontation-generating; identification will be highest where composition is support-generating; and internalisation will be highest where both some support and some confrontation are present. The hypotheses were tested in sixteen one-day experimentally composed T-groups. All the hypotheses were supported, particularly the first two. In this setting internalisation was found to be related to confrontation but not to support.     

The influence of social comparison on career decision-making: Vocational identity as a moderator and regret as a mediator

This study investigated the influence of social comparison on career choice certainty and its potential mechanisms: regret as a mediator and vocational identity as a moderator. Before the formal experiment, 30 pairs of vocational values representing typical conflicts in career decision-making for Chinese university students were obtained. The formal experiment adopted a single-factor (social comparison VS no comparison) between-subject design with vocational identity as an independent covariate. Ninety-eight junior and senior undergraduate students and graduate students in a university in China were invited to participate in the computer-controlled experiment, which involved vocational identity assessment, social comparison manipulation, and analogue career-choice scenario tests. Path analysis showed that: (a) Social comparison significantly and negatively predicted career choice certainty; (b) Regret partially mediated the effect of social comparison on career choice certainty; and (c) Vocational identity did not moderate the path between social comparison and regret, but significantly moderated the negative effect of regret on career choice certainty. These results indicated that in the collectivistic Chinese culture, individuals' career development trajectories may not be totally independent and are subject to influences by other people's choices, while emotion of regret and vocational identity development all play significant roles in this intricate process.     

The role of social categorization and perceived source credibility in minority influence

This study was conducted in order to compare the influence of ingroup and outgroup minorities and to assess the role of perceived source credibility in minority influence. The subjects were exposed to the simultaneous majority/minority influence paradigm. Ingroup minorities were more influential than outgroup minorities. Subjects moved toward the minority position in private and toward the majority position in public when the minority was represented by members of the ingroup. On private responses subjects were not affected by outgroup minorities who argued for abortion, and they became more positive toward abortion when outgroup minorities opposed abortion. Final &, ingroup minorities were perceived as more credible than outgroup minorities and greater credibility of minority source was associated with greater attitude change toward the minority position. The superior influence of ingroup minorities held when controlling for source credibility. Overall, the results were highly supportive of social identity theory.     

The influence of individuals on situations: Implications for understanding the links between personality and social behavior

In an analysis of the nature and origins of predictability in social behavior, two propositions are considered: (1) There exist categories of individuals whose social behavior is readily predictable from measures of personal attributes such as attitudes, traits, and dispositions as well as categories of individuals whose social behavior is readily predictable from situational and interpersonal specifications of behavioral appropriateness; (2) underlying these differences in predictability are systematic choices to enter and to spend time in social settings and interpersonal contexts that promote and facilitate one or other of these characteristic behavioral orientations. The implications of these propositions for the study of personality and social behavior are considered in the specific case of the psychological construct of self-monitoring and in the general case of understanding the reciprocal influences of individuals and their social worlds.     

PTSD and the influence of context: The self as a social mirror

The principal accepted models of posttraumatic stress disorder (PTSD) are based on both memory processing and biological/brain changes occurring when one's life or well-being is threatened. It is our thesis that these models would be greatly informed by community studies indicating that PTSD is predicted to a greater extent by earlier life experience and experiences that occur distant from the threatening event. These findings suggest posttraumatic responding is best conceptualized through the lens of the self-in-context, as opposed to imprinting that results from a given event at a given time. Moreover, studies of non-Western populations often do not express trauma as PTSD, or at least not primarily as PTSD, which argues against specific neural or memory encoding processes, but rather for a more plastic neural process that is shaped by experience and how the self develops in its cultural context, as a product of a broad array of experiences. We posit that fear and emotional conditioning as well as the ways traumas are encoded in memory are only partial explanatory mechanisms for trauma responding, and that issues of safety and harm, which are long term and developmental, are the common and principal underpinnings of the occurrence of posttraumatic distress, including PTSD.     

Events and the ontology of individuals: verbs as a source of individuating mass and count nouns

What does mass-count syntax contribute to the interpretation of noun phrases (NPs), and how much of NP meaning is contributed by lexical items alone? Many have argued that count syntax specifies reference to countable individuals (e.g., cats) while mass syntax specifies reference to unindividuated entities (e.g., water). We evaluated this claim using the quantity judgment method, and tested the interpretation of words used in mass and count syntax that described either protracted, "durative" events (e.g., mass: some dancing; count: a dance), or instantaneous, "punctual" events (e.g., mass: some jumping; count: a jump). For durative words, participants judged, for example, that six brief dances are more dances but less dancing than two long dances, thus showing a significant difference in their interpretation of the count and mass usages. However, for punctual words, participants judged, for example, that six small jumps are both more jumps and more jumping than two long jumps, resulting in no difference due to mass-count syntax. Further, when asked which dimensions are important for comparing quantities of durative and punctual events, participants ranked number as first in importance for durative and punctual words presented in count syntax, but also for punctual words presented in mass syntax. These results indicate that names for punctual events individuate when used in either mass or count syntax, and thus provide evidence against the idea that mass syntax forces an unindividuated construal. They also indicate that event punctuality as encoded by verbs is importantly linked to the individuation of NPs, and may access a common underlying ontology of individuals.     

Factors effecting nonreinforced imitation: the model as a source of information or social control

Three experiments were conducted with kindergarten, second-grade, and fourth-grade children (N = 208) which investigated whether modelling of unreinforced behavior exerts control over childrens' behavior by providing information concerning other types of behavior more likely to be reinforced or by creating social demands for imitation. After learning that reinforcement was available, children observed an adult model emit a reinforced response or an unreinforced response and then remain to monitor the child's subsequent behavior or leave the situation. Compared to a no-model control, all children except kindergarten girls emitted more reinforced responses after observing the model being reinforced. Only second-grade children, however, showed performance changes after observing the unreinforced model. Second-grade children also only performed what they learned when the unreinforced model was not present. Conclusions were that the unreinforced behavior of the model serves not only as a source of information but also as a cue for unreinforced imitation.     

Further studies on the mathematical theory of interaction of individuals in a social group

A type of interaction of two active groups is considered, in which the opposition of each group increases as the success of the other increases. Some possible applications of this situation are discussed.
