A study on the resistance of observation systems of observers' expectancies

Different sets of expectations were induced in groups of observers before asking them to observe a film. Four aspects of Hall's notation system for the observation of proxemic behavior (1963) were adopted for the purposes of this study and another observation aspect was added. All Ss observed the same scenes of the film. They only differed in the kind of information on experimenters' beliefs and the hypotheses of the observation study. Results indicate that induced expectancies influenced the recordings of the observers. Implications of these outcomes are discussed.     

Further observational data on the behavioral and social world of institutions for the aged

This study is an extension of previous observational work on the social ecology of dependence and independence in the institutionalized elderly. Observations of everyday, naturally occurring interactions between elderly residents of two different long-term institutions and their social partners were extended such that, aside from the identification of type of behavior, the dyadic form and continuity of each behavior was specified. The following were among the major results: (a) Previously found interaction patterns between elderly residents and their social partners, replicated in both a nursing home and a home for the chronically ill, supported the notion of discrepant social ecologies for dependent versus independent behaviors of residents: (b) specification of each behavioral act as to its dyadic form underscored the fact that the interactions were controlled largely by social partners and not by the elderly residents; (c) coding continuity or discontinuity of behavior suggested that independent behaviors were maintained by chaining; and (d) elderly residents in the home for the chronically ill evinced, as expected, more dependence-related behaviors.     

An Ecologically Differentiated, Multifactor Model of Adolescent Network Orientation

The paper presents a test of an ecologically differentiated model of social network orientation for adolescents that distinguished between different social network reference groups (family, peers, and nonfamily adults). The model was tested in two consecutive studies. Study 1 describes initial model development (N = 120). Study 2 presents a confirmatory factor analysis with a second sample (N = 430) to replicate the factor structure developed in Study 1. Results supported a three-factor model of network orientation that differentiated between network reference groups. Analyses of concurrent and predictive validity indicated that orientation to network reference groups was differentially related to the perceived quality and frequency of support from members of respective social network groups. Group differences (gender, race) regarding network orientation to different network reference groups were consistent with studies of other social network processes. Implications for the study of the network orientation and the study of social networks more generally are discussed.     

Swiss Adolescent Drug Users' and Nonusers' Optimism About Their Future1

Swiss adolescents, aged 16 to 17 years, were asked about their past drug use, their intended drug use, their optimism about their future health, their negative emotions, and their well-being. On the basis of their self-reports, they were divided into 3 types of drug users: nonusers, experimenters, and frequent users. Compared with nonusers, experimenters and frequent users reported low optimism and more negative feelings. Females reported more negative feelings and less psychological well-being than did males, but the genders did not differ regarding optimism. Logistic regression demonstrated that optimism about future health was a protective factor for the intention to use drugs. Students who perceived themselves as less vulnerable to harm had in the past not used drugs and intended not to accept drugs when given the occasion. The implications of the findings for prevention of drug use are discussed.     

The Promotion of New Behavior by Forming an Implementation Intention: Results of a Field Experiment in the Domain of Travel Mode Choice1

In the context of an experimental field study, it is analyzed whether furnishing a goal intention with an implementation intention (Gollwitzer, 1993) increases the probability that a new behavior is enacted. For this purpose, 90 students who did not normally use public transportation were asked to test (just one time) a special public transportation offer they had never used before. With a nonobstrusive questionnaire manipulation, the subjects of the experimental group were stimulated to form an implementation intention. The results show that forming an implementation intention significantly increases the probability of enacting the goal intention; that is, testing the public transportation offer. The theoretical and practical implications of this finding are discussed.
