The Influence of American Urban Culture on the Development of Normative Beliefs About Aggression in Middle-Eastern Immigrants

The effects of a community's culture on children's and adolescents' normative beliefs about the appropriateness of aggression were examined. One hundred forty-seven high school students and 103 fourth graders participated in a survey of normative beliefs; 69 high school and 44 elementary school students were of Middle-Eastern background. Although there were no differences in the beliefs of immigrant and nonimmigrant fourth graders, adolescents born in the United States were more accepting of aggression than those who immigrated from the Middle East. Moreover, adolescents who immigrated to the U.S. at age 12 or later were less accepting of aggression than those who immigrated prior to age 12.     

The relationship between perception and production of /w/, /r/, and /l/ by three-year-old children

Twenty-one normally developing 3-year-old children were tested on two approximant consonant contrasts, rake-lake and wake-rake, and a control contrast, wake-bake. Perception was assessed in a two-choice picture identification paradigm; stimuli were (1) natural and computer synthesized “clear cases” of the minimal pairs, and (2) synthetic stimulus series which interpolated on acoustic dimensions that differentiate the minimal pairs. As a group, the children showed very accurate perception of the minimal pairs. Performance on the synthetic series yielded consistent identification of the endpoint stimuli and monotonic functions with abrupt crossovers at the phoneme boundary. Children who did not yet articulate /r/ and /l/ appropriately showed somewhat less consistent perception than children who produced all phonemes correctly.     

Predictions of X-linked inheritance for human characteristics

The conclusion reached by H. Thomas and W. Jamison (Developmental Review, 1981, 1, 274–283) that an observed sex-related difference in water-level task performance is due to an X-linked major gene raises the question of whether available data would be consistent with X-linkage predictions other than the one tested. Several predictions of X-linked inheritance for human characteristics are presented and discussed. It was concluded that although water-level task performance may involve a heritable component, the available data from seven independent studies reviewed by Thomas and Jamison are insufficient for determining the specific mode of genetic transmission.     

The development of communication: When a bad model makes a good teacher

Five experiments were conducted on what 6-year-old children learn about communication by switching listener and speaker roles with competent and incompetent adults and peers. Experiment I demonstrated that children become better communicators to adults after listening to competent adults, competent peers, and incompetent peers, but not incompetent adults. The age of the listener was shown to have an effect in Experiment II, with children becoming less effective communicators when speaking to a peer after listening to an incompetent peer but better communicators when speaking to an adult after listening to an incompetent peer. Experiments III, IV, and V were designed to determine why children do not improve or deteriorate after listening to incompetent adults. It is not deficient memory: Children remember well the ambiguous messages of adults (Experiment IV). It is not implicit demands to be polite to an adult (Experiment III). It is that children think the ambiguous messages of an adult are competent (Experiment V). Mixing the authority and prestige of an adult with incompetent messages leads the child to ignore the adult's behavior as a standard for his or her own performance. These results suggest that social learning of communication skills might occur best when the child can learn what not to do by interacting with peers and what to do when interacting with adults.     

A developmental study of semantic elaboration and interpretation in recognition memory

Two experiments examined semantic elaboration and interpretation in recognition memory of 4-year-olds and college students. Subjects were presented pictures of color-specific and non-color-specific items, and then tested for their recognition of the chroma of the items. In Experiment 1, one-half of the presentation items were black and white and one-half colored, and testing always involved one black and white and one colored choice. In Experiment 2, all of the presentation items were colored, and testing always involved two colored choices. In both studies, the pattern of results of the two age groups was similar. Experiments 1 and 2 indicated that recognition judgments were based on representations that were elaborated with preexperimentally acquired semantic color information, and Experiment 2 also indicated that recognition judgments were based on representations that contained interpretive information about the appropriateness of the colors of the items. The results were considered to support and extend the view that when young children and adults share a common knowledge base, they are likely to engage in similar and extensive semantic processing.     

Belief discrepant behavior and the bogus pipeline: Impression management or arousal attribution

Based on recent studies impression management theorists conclude that following belief discrepant behavior, persons will feign attitude change on paper measures, but report their “true” beliefs when attached to a lie detector (the bogus pipeline). A dissonance arousal explanation of these bogus pipeline results suggests that subjects may attribute their arousal to the bogus pipeline equipment instead of to dissonance and therefore may not be motivated to change their attitudes. The present study examined these competing interpretations and yielded results which support the dissonance arousal attribution explanation. Subjects who were attached to a (bogus pipeline) lie detector exhibited attitude change if given the opportunity to get accustomed to the equipment (which made attribution of arousal to the equipment less plausible), but showed no attitude change if no habituation experience was provided.     

The influence of incentive-aroused ambivalence on overjustification effects in attitude change

Rewarding people to advocate a position with which they already agree can undermine their attitudinal positivity. This research tests a novel explanation of this example of the overjustification phenomenon. The hypothesis holds that the provision of an unnecessary incentive gives rise to an ambivalent response: the positive reaction to the reinforcement is accompanied by a sense of uneasiness, or apprehension, regarding the legitimacy of the induced behaviors. Attitude change is expected only in circumstances that confirm the apprehension. Results consistent with this expectation were discovered. In Study 1, respondents asked to play the role of a subject in an overjustification experiment reported greater levels of ambivalence regarding their (role-played) proattitudinal action as a function of payment. Contrary to alternative interpretations of the phenomenon, no incentive-related differences were found in subjects' ratings of the reprehensibility of the requested action, or in their beliefs that future activities of the type requested be undertaken only for payment. In Study 2, subjects paid to read a proattitudinal speech were found subsequently to be less in favor of their original positions only if they also had been given a counterattitudinal communication. The presence or absence of the countercommunication had no influence on the attitudes of unpaid respondents. Subjects for whom the payment was made to appear incidental to the experiment did not demonstrate the usual overjustification effect. These results supported the incentive-aroused ambivalence hypothesis. Psychological mechanisms that might underlie the effect were discussed.
