Interactive effects of writing and reading a persuasive essay on attitude change and selective exposure

Subjects wrote an essay either supporting their own position on an issue or irrelevant to that issue. Subsequently, they received a communication that either supported or opposed their position, and that either claimed to present the only reasonable position or acknowledged the viability of alternative positions. Then, they reported their own beliefs in the position being advocated, and finally were given an opportunity to obtain subsequent information that either supported or opposed this position. Attitude change in the direction of a proattitudinal communication occurred only when both (a) this communication asserted that only the position advocated was defensible and (b) subjects had previously written a proattitudinal essay themselves. Moreover, either of these factors was sufficient to prevent attitude change in the direction of a counterattitudinal communication. Data supported predictions based upon a joint consideration of commitment and reactance effects. Subjects' subsequent preference for supporting over opposing information was greater when they had written a supporting essay than when they had not, greater when they had read an opposing communication than when they had read a supporting one, and greater when the communication they read was presented as stating the only reasonable position, no matter which position it advocated.     

Modeling instrumental agression in adults in a laboratory setting

Summary Five experiments with 353 young adults performing a game on an aggression machine are reported, three of them testing hypotheses concerning the effects of a model's aggressiveness and social status on instrumental aggressive behavior, and two investigating aspects of reliability and validity. Model's aggressiveness increased the Ss' aggressive behavior in all experiments. The use of presumptive monetary losses as a means by which SS punish their opponents in aggression machine experiments is as effective as presumed electric shocks, and therefore seems preferable in further experimental studies of aggression.

Zusammenfassung Es wird über fünf Experimente mit insgesamt 353 jüngeren Erwachsenen als Versuchspersonen berichtet, deren instrumentell-aggressives Verhalten an einem Aggressionssimulator untersucht wird. Drei der Experimente dienten der Prüfung von Hypothesen über den Einfluß von Modell-Aggression und Modell-Status auf instrumentell-aggressives Verhalten, zwei weitere untersuchten Aspekte der Reliabilität und Validität. In allen Experimenten zeigte sich ein Anwachsen aggressiven Verhaltens, wenn das Modell aggressiv war. Ferner ergab sich, daß die Verwendung angeblicher Geldstrafen als Mittel, den Gegenspieler an der Aggressionsmaschine zum Rückzug zu zwingen, in gleichem Maße effizient war wie die Vergabe angeblicher Elektroschocks. Daher wird der Verwendung von Geldstrafen in weiteren Aggressionsexperimenten der Vorzug gegeben.

Some conditions to produce a dissonance and an incentive effect in a ‘forced-compliance’ situationx

Dissonance theory and incentive theory call for different predictions concerning the relation of reward and attitude change after a person has performed some counter-attitudinal behavior. According to dissonance theory a negative, and according to incentive theory a positive relationship is expected. An experiment was conducted in West Germany testing the interactions of choice versus no choice and public versus anonymus (private) essay-writing. A dissonance effect was predicted for the choice/public condition and an incentive effect for the no choice/anonymus condition. The results support these predictions.     

Ego depletion and positive illusions: does the construction of positivity require regulatory resources?

Individuals frequently exhibit positive illusions about their own abilities, their possibilities to control their environment, and future expectations. The authors propose that positive illusions require resources of self-control, which is considered to be a limited resource similar to energy or strength. Five studies revealed that people with depleted self-regulatory resources indeed exhibited a less-optimistic sense of their own abilities (Study 1), a lower sense of subjective control (Study 2), and less-optimistic expectations about their future (Study 3). Two further studies shed light on the underlying psychological process: Ego-depleted (compared to nondepleted) individuals generated/retrieved less positive self-relevant attributes (Studies 4 and 5) and reported a lower sense of general self-efficacy (Study 5), which both partially mediated the impact of ego depletion on positive self-views (Study 5).     

Terror salience and punishment: Does terror salience induce threat to social order?

In recent times, international terrorism has become one of the most serious concerns of the modern Western world. As a consequence, the risk and fear of terrorism is more salient in people’s minds (i.e. terror salience), which is supposed to affect behavioral responses in our society. The present research suggests that increased punishment of violations of criminal laws is one societal reaction to increased terror salience. It was consistently shown that increased terror salience, induced by either varying the temporal distance from the London terrorist attacks of July 7, 2005 (Study 1), by vignettes in the form of newspaper articles manipulating the expected terror risk (Study 2), or by pictures of recent terrorist attacks (Studies 3 and 4), significantly increased the punishment assigned to a violation of criminal laws that was completely unrelated to terror (i.e. car theft and rape). Finally, Study 4 revealed that (a) the effect of terror salience on punishment is indeed due to increased perception of threat to social order and (b) that this effect cannot be explained by the general negative nature of the stimulus material employed in this study.

The influence of infant irritability on maternal sensitivity in a sample of very premature infants

The relationship between maternal sensitivity and infant irritability was investigated in a short‐term longitudinal study of 29 very preterm infants. Infant irritability was assessed at term with the Brazelton NBAS, the Mother and Baby Scales (MABS) and the Crying Pattern Questionnaire (CPQ). Maternal sensitivity was assessed by nurses' ratings in the neonatal care unit and at three months during mother–infant interaction observation. Cross‐lagged panel analysis indicated that neonatal irritability did not influence sensitivity at 3 months nor did maternal sensitivity in the newborn period lead to reduced irritability at 3 months. Both irritability and maternal sensitivity showed moderate stability over time (r = 0.55 and r = 0.60, respectively). It is concluded that in early infancy maternal sensitivity shows little influence on infant irritability in very preterm infants. Copyright © 2003 John Wiley & Sons, Ltd.
