Aspects of body image perception in obese and normal-weight youngsters

Perceptual and projective aspects of body image in obese youngsters (not in psychological treatment) and normal-weight youngsters 8–9 years of age and 12–13 years of age were investigated. The results indicate that perceptual distortions in estimating various body dimensions of oneself are primarily a function of age rather than weight status. The accuracy of estimating the weight of peers and an adult showed an association with the sex of the subject. No group differences were found in terms of projective aspects of body image as measured by barrier and penetration responses. This study suggests that obese youngsters in the middle childhood and entering puberty periods in comparison to normal-weight youngsters of the same age do not manifest differences in perceptual factors of body image.     

Consequences of confirmation and disconfirmation in a simulated research environment

Advanced undergraduate science majors attempted for approximately 10h each to discover the laws governing a dynamic system. The system included 27 fixed objects, some of which influenced the direction of a moving particle. At a given time, any one screen of a nine-screen matrix could be observed on a plasma display screen. Confirmatory strategies were the rule, even though half the subjects had been carefully instructed in strong inference. Falsification was counterproductive for some subjects. It seems that a firm base of inductive generalizations, supported by confirmatory research, is a prerequisite to useful implementation of a falsification strategy.     

Laboratory and field interview methods for the study of shiftworkers

Gordon, Tepas, Stock, and Walsh (1979) describe the manner in which shiftworkers were selected as research subjects through the cooperation of labor union organizations. In this paper, we describe the methods used to select and orient the workers to serve in a laboratory study involving measurement of the psychophysiological correlates of sleep. Procedures used for field interviews with the same subjects are also described. Some of the advantages and disadvantages of using a multimethod (laboratory and field interview) approach to the study of shiftwork effects are detailed.     

Aggression in dyadic interaction

It is shown that the notions of aggressive behavior as ‘intentional emission of noxious stimulation’ (Buss, 1961, 1963, 1966, 1971) and that of ‘injuriating goal response’ (Dollard, Doob, Miller, Mower and Sears, 1939) are identical. The usefulness of these theories to predict S's reaction to the reception of a given noxious stimulation is questioned. It is suggested that S's reactions to noxious stimulation may or may not be aggressive, depending on whether the noxious stimulation S receives is interpreted as being a behavior justified by the nom in the situation, or as reflecting an aggressive intent of O. It is hypothesized that the norms established in the situation depend on (i) victim's perception of the noxious stimulation received as being instrumental for O's goal attainment, (ii) victim's perception of the value of O's goal, and (iii) the value of victim's own goal. The establishment of norms regulating the exchange of noxious stimulation between Ss is operationalized in two experiments. Aggression, defined as an infringement of these norms, is measured. In Experiment I, participate 56 female students, and in Experiment 2, 80 male students. Subject is alternately victim (he performs a sensorimotor task and receives an electric shock) and aggressor (he shocks the other S). In Experiment I it is found that Ss counteraggress faster and more frequently if they interpret the shock received from the partner as an infringement of the norm. In Experiment 2, Ss do not counteraggress more frequently, but they do counteraggress faster and evaluate O more negatively. It is concluded that the results clearly contradict current positions and favor the authors' cognitive reformulation of the determinants of aggressive behavior.     

Confirmation bias in a simulated research environment: An experimental study of scientific inference

Numerous authors (e.g., Popper, 1959) argue that scientists should try to falsify rather than confirm theories. However, recent empirical work (Wason and Johnson-Laird, 1972) suggests the existence of a confirmation bias, at least on abstract problems. Using a more realistic, computer controlled environment modeled after a real research setting, subjects in this study first formulated hypotheses about the laws governing events occurring in the environment. They then chose between pairs of environments in which they could: (I) make observations which would probably confirm these hypotheses, or (2) test alternative hypotheses. Strong evidence for a confirmation bias involving failure to choose environments allowing tests of alternative hypotheses was found. However, when subjects did obtain explicit falsifying information, they used this information to reject incorrect hypotheses.     

Instrumental Behaviors Following Test Administration and Interpretation: Exploration Validity of the Strong Interest Inventory

A two-phase longitudinal study was conducted to explore the exploration validity (i.e., the power of interest inventories to facilitate career exploration activities such as talking to professionals and seeking vocational information) of the 1985 Strong Interest Inventory (SII) for college students. Participants in the study included an experimental group (N =75), which participated in the SII testing and a group interpretation, and a contrast group(N=67). Students in the experimental group reported significantly more instrumental career exploration behaviors at a 1-year follow-up than did the contrast group.     

Interrelationships of personality and coping in a challenging extreme situation

The relationship between personality characteristics, daily stressors, and means of coping were studied in a 12-person Soviet-American expedition ateamconsisting of Caucasian and Eskimo men and women. The members scored relatively high on scales measuring well-being, achievement orientation, and traditionalism and scored relatively low on stress reactivity. The use of social support as a coping mechanism was positively related to high stress reactivity, control, and negative emotionality and negatively related to well-being. Negative emotionality was related to ratings of daily intrapersonal stressor. Discussion centered on the function of social support in an extreme, task-focused situation and the relationship of social support coping in this particular type of situation to maladaptive personality characteristics.     

A Comparison of Anglo-American and Mexican-American Jurors' Judgments of Mothers Who Fail to Protect Their Children from Abuse1

Two studies were conducted to determine if people with an individualist cultural background differ from those with a collectivist cultural background (Triandis, 1990) in their adjudication of mothers who fail to protect their children from abuse. In the first study, 452 students evaluated the case of a mother accused of failure to protect her son from physical abuse. In the second study, an additional 334 subjects considered a case of a mother's failure to protect her daughter from sexual abuse. While the verdicts depended on the gender of the juror, female jurors were significantly more likely to convict the defendant; the verdict was independent of ethnicity. However, ethnicity did influence sentencing and whether the juror recommended that the defendant serve time. The results are discussed in terms of cultural influences on discretionary decisions.     

Pre- and postlexical loci of contextual effects on word recognition

The context in which a word occurs could influence either the actual decoding of the word or a postrecognition judgment of the relatedness of word and context. In this research, we investigated the loci of contextual effects that occur in lexical priming, when prime and target words are related along different dimensions. Both lexical decision and naming tasks were used because previous research had suggested that they are differentially sensitive to postlexical processing. Semantic and associative priming occurred with both tasks. Other facilitative contextual effects, due to syntactic relations between words, backward associations, or changes in the proportion of related items, occurred only with the lexical decision task. The results indicate that only associative and semantic priming facilitate the decoding of a target; the other effects are postlexical. The results are related to the different demands of the naming and lexical decision tasks, and to current models of word recognition.
