Valence of self-cognitions: the positivity of individual self-statements.

Based on D. Trafimow, H. C. Triandis, and S. Goto's (1991) research on the distinction between the private, collective, and relational selves, the present authors explored the valence of each self. The authors administered to participants either a private self-prime, a collective self-prime, or a relational self-prime and then asked them to write 20 self-statements. The authors coded the statements for valence (positive, neutral, or negative) and self-statement type (individual, collective, or relational). The results indicated that the valence of individual self-statements were most positive when the collective self or the relational self was primed, indicating the possibility that positive illusions were exaggerated most in the context of other people.

The role of affect in determining the attributional weight of immoral behaviors.

Theories about why immoral behaviors carry a large amount of attributional weight tend to emphasize traditional cognitive variables. In contrast, the authors propose that the degree of negative affect that these behaviors induce in observers is largely responsible for their attributional weight. Studies 1 and 2 demonstrate an association between the amount of negative affect induced by immoral behaviors and their attributional weight. Studies 3 and 4 provide causal evidence for this idea by either "adding in" or "taking away" the negative affect associated with immoral behaviors to influence their attributional weight. Finally, Study 5 demonstrates that negative affect can be induced through a variety of negative emotions (disgust, sadness, and fear), with similar results. It is argued that it is difficult to account for these data solely on the basis of traditional cognitive variables, and so a theory that includes an emphasis on affect as a causal variable is desirable.

The generality of negative hierarchically restrictive behaviours.

Previous research has shown that when an actor engages in a negative hierarchically restrictive behaviour, a strong correspondent trait attribution is made and this behaviour is expected to generalize across situations (Trafimow, 2001). This paper discusses three experiments that examined the effects of extreme situations and perceived morality of the actor on the way in which participants make trait attributions, and the extent to which those behaviours are expected to generalize to other situations. Findings from Experiments 1 and 2 indicate that even negative hierarchically restrictive behaviours do not always lead to strong correspondent inferences if the situation in which the initial behaviour was performed was sufficiently extreme. Experiment 3 served to support these findings and cleared up questions from the first two experiments. Findings supported the hypothesis that some situations inhibit negative trait attributions and behaviour generalizations. Furthermore, findings indicate that the perception of the morality of the actor determines whether or not a negative hierarchically restrictive behaviour will lead to a negative trait attribution and generalization.

Affective and cognitive control of persons and behaviours.

Three studies assessed the relative contribution of affect and cognition to determining behavioural intentions for a variety of behaviours using both between-participants and within-participants analyses. The between-participants analyses showed that affect tends to make more of a contribution than does cognition for more behaviours. However, the within-participants analyses indicated that there are strong individual differences among people. Some people are more under affective control, across behaviours, whereas other people are more under cognitive control. The most interesting finding was that, despite the potential independence of between-participants and within-participants analyses (Mischela, 1990), between-participants analyses on subsamples created from the within-participants analyses showed significant dependence. The predictive validity of affect vs. cognition depended upon whether participants were affectively or cognitively controlled.

Problems with change in R2 as applied to theory of reasoned action research.

The paradigm of choice for theory of reasoned action research seems to depend largely on the notion of change in variance accounted for (DeltaR2) as new independent variables are added to a multiple regression equation. If adding a particular independent variable of interest increases the variance in the dependent variable that can be accounted for by the list of independent variables, then the research is deemed to be 'successful', and the researcher is considered to have made a convincing argument about the importance of the new variable. In contrast to this trend, I present arguments that suggest serious problems with the paradigm, and conclude that studies on attitude-behaviour relations would advance the field of psychology to a far greater extent if researchers abandoned it.

A test of whether attributions provide for self-enhancement or self-defense.

It is well known that people often make attributions in a way that is favorable to their self-concepts (see R. L. Collins, 1996, for a review). However, it is less clear whether the primary effect is to enhance self-esteem or to defend against the possible loss of self-esteem. The authors performed an experiment to test these possibilities against each other. In a completely between-participants design, participants recalled either a positive behavior or a negative behavior that was performed by themselves or others. They then judged the positivity or negativity of the behavior and made trait attributions about the actor (i.e., himself, herself, or others). The results indicated that although judgments and trait attributions for positive behaviors were similar for the self and for others, judgments and trait attributions for negative behaviors were less negative for the self than they were for others. The authors interpreted these and other findings as supporting a defensive strategy rather than an enhancive strategy.

Hypothesis testing and theory evaluation at the boundaries: surprising insights from Bayes's theorem.

Because the probability of obtaining an experimental finding given that the null hypothesis is true [p(F\H0)] is not the same as the probability that the null hypothesis is true given a finding [p(H0\F)], calculating the former probability does not justify conclusions about the latter one. As the standard null-hypothesis significance-testing procedure does just that, it is logically invalid (J. Cohen, 1994). Theoretically, Bayes's theorem yields p(H0\F), but in practice, researchers rarely know the correct values for 2 of the variables in the theorem. Nevertheless, by considering a wide range of possible values for the unknown variables, it is possible to calculate a range of theoretical values for p(H0\F) and to draw conclusions about both hypothesis testing and theory evaluation.

Predicting behaviour from perceived behavioural control: tests of the accuracy assumption of the theory of planned behaviour.

The theory of planned behaviour assumes that the accuracy of perceived behavioural control (PBC) determines the strength of the PBC-behaviour relationship. However, this assumption has never been formally tested. The present research developed and validated a proxy measure of actual control (PMAC) in order to test the assumption. In two studies, participants completed measures of intention and PBC, and subsequently completed measures of behaviour and the PMAC. Validity of the PMAC was established by findings showing; (a). that the PMAC moderated the intention-behaviour relation, and (b). that PMAC scores did not reflect attributions for participants' failure to enact their stated intentions. Accuracy was operationalized as the difference between PBC and PMAC scores. Consistent with theoretical expectations, several analyses indicated that greater accuracy of PBC was associated with improved prediction of behaviour by PBC.

Generalization of the negativity effect to self-attributions.

In 1979 Reeder and Brewer reported that people make stronger attributions for negative behaviors than for positive ones, following Hastorf and Cantril's statement that people are motivated to maintain positive self-views. The present study tested whether 67 participants would make stronger self-attributions for negative behaviors than for positive ones by having them indicate the number of times that they had to engage in a specific behavior before it would become a trait they possess. Analysis confirmed that participants make stronger self-attributions for negative behaviors than for positive behaviors.

Inferences about the morality of an aggressor: the role of perceived motive.

The research investigated perceivers' inferences about the morality of target persons who engaged in aggressive behavior. Across several experiments, inferences about the morality of an aggressor were based more on the perceived motives of the target than on the presence of facilitating situational forces. For example, when a target's aggression was facilitated by personal rewards for aggression (instrumental aggression), perceivers inferred more negative motives and attributed lower morality to the target than when the target's aggression was facilitated by situational provocation (reactive aggression). The results suggest that perceived motives play an important role in dispositional inference and pose a problem for models that focus primarily on perceived causality, assumptions about base rates (consensus), or diagnosticity.

The prediction of attitudes from beliefs and evaluations: the logic of the double negative.

One of the most intriguing aspects of Fishbein's (e.g. 1980) theory of reasoned action is the logic of the double negative: if a behaviour is thought to be unlikely to result in a negatively evaluated consequence, then the product of the two negatives (an unlikely consequence that is negatively valued) is thought to provide an impetus for the formation of a positive attitude towards the behaviour. The present experiment tested two derivations from the logic of the double negative. First, according to this logic, whether beliefs and evaluations are positively or negatively framed should not affect their ability to predict attitudes. Second, the multiplicative assumption of this logic (a negative x negative = a positive) suggests that a multiplicative model should be a superior predictor of attitudes compared to an additive model that does not allow for the logic of the double negative. The obtained findings contradicted both of these predictions.

Evidence that perceived behavioural control is a multidimensional construct: perceived control and perceived difficulty.

Four studies were performed to test whether Ajzen's (1988, 1991) concept of perceived behavioural control is really an amalgamation of two variables, which we term 'perceived control' and 'perceived difficulty'. Perceived control refers to the extent to which people consider the performance of a behaviour to be under their voluntary control. Perceived difficulty refers to whether people consider a behaviour to be easy or difficult to perform, Findings from Studies 1 to 4 demonstrate that it is possible to perform manipulations that affect perceived control more than perceived difficulty, or that affect perceived difficulty more than perceived control. Studies 2-4 used a variety of paradigms to show that people distinguish between beliefs that are presumed to underlie perceived control and perceived difficulty. Finally, we performed a meta-analysis in Study 5 to determine whether perceived control or perceived difficulty is more important for predicting behavioural intentions and behaviours. Taken together, the findings support the distinction between perceived control and perceived difficulty, and also suggest that perceived difficulty is a better predictor of most behavioural intentions and behaviours than is perceived control.

Evidence that the type of person affects the strength of the perceived behavioural control-intention relationship.

This study examined the role of person type in explaining the relationship between perceived behavioural control and behavioural intentions. Participants (N = 187) completed measures of the theory of planned behaviour (Ajzen, 1991) variables regarding 30 behaviours. Within-participants analyses demonstrated that intentions were more strongly predicted by perceived behavioural control (PBC) than a combination of attitudes and subjective norms among a minority of the sample. When these 'PBC controlled' participants were considered separately, the effects for perceived behavioural control obtained in previous between-participants analyses were augmented. Conversely, when these participants were excluded from the sample, the effects of perceived behavioural control were reduced. PBC control was also modestly associated with dispositional measures of perceived controllability. Overall, the findings indicate that the strength of the perceived behavioural control-intention relationship depends not only on the type of behaviour but also on the type of person.

The relative influence of attitudes and subjective norms from childhood to adolescence: between-participant and within-participant analyses.

Children and adolescents (ages 8-16) were asked to indicate their behavioral intentions, attitudes, and subjective norms for 34 behaviors. Between-participant and within-participant analyses demonstrated that attitudes and subjective norms were good predictors of behavioral intentions both singly and in combination. In addition, attitudes generally were better predictors than were subjective norms both across behaviors and across participants. Most importantly, however, there were no differences in the relative importance of attitudes and subjective norms in predicting behavioral intentions across age groups.
