The effects of affective states on the formation of performance expectancies

Positive vs. negative affective states are associated with the use of broad vs. specific knowledge structures. These findings were applied to the field of performance expectancies. It was predicted that individuals with positive mood should infer their performance expectancies concerning a specific task from their general self-concept, whereas given negative mood, performance expectancies should be inferred from the relevant specific self-concept. In an experiment, positive vs. negative mood was induced in 158 university students. General and specific self-concepts were assessed. Furthermore, we assessed task-specific performance expectancies and task performance. Specific self-concept was predictive of expectancies given negative mood, whereas with positive mood, expectancies could only be predicted on the basis of the general self-concept. Furthermore, mean expectancies were higher and less accurate with positive mood. The results are in line with the theoretical predictions. They underline that affective states also influence the formation of motivational variables like performance expectancies.     

Desire and the Good in Plotinus

Plotinus calls the first principle the One and the Good. According to Plotinus, ‘Good’ is an appropriate name for the One because the One is that which all things desire. Since he says that the One is beyond knowledge, beyond language, beyond intellect, and beyond being, however, what philosophical evidence can he provide for his claim that the One is that which all desire? In this article I offer some philosophical evidence, aside from mystical union with the One, for why ‘the Good’ is an appropriate name for the One, and for why calling the One ‘Good’ is not at odds with the fact that it is beyond knowledge, but rather entails it. To this end, after an initial consideration of the relationship between the good and desire in Plato and Aristotle, I focus on the role that desire plays in relation to the Good in Plotinus' thought.     

Love Actually: A Theodicy Response to Suffering in Nature. In Dialogue with Francisco Ayala1

Suffering is an inevitable corollary of evolution and as such exacerbates the problem of evil in a world created by an omnipotent, omniscient, and omnibenevolent God. Recent responses to this dilemma often emphasize cosmic creativity as an end that justifies the means. The present paper will review one example of such creativity defenses (Francisco Ayala's) and attempt an alternative theodic approach that seeks to incorporate creativity as a means rather than an end. For that, it will propose a radical turn to love, where suffering is seen as a necessary condition for the possibility of the full actualization of love.     

Intergenerational Transmission of Trauma: The Mediating Role of Parenting Styles on Toddlers' DSM-Related Symptoms

Although the intergenerational transmission of trauma has been well documented, the pathways by which trauma symptoms are passed between parents and children remain unclear. This study examined the mediating role of parenting styles in the transmission of maternal trauma to children. Participants were a sample of 105 mothers of toddlers (18–30 months old). Mothers who had experienced interpersonal trauma were more likely to have an authoritarian parenting style, including verbal hostility, physical coercion, and low nurturance. Verbal hostility especially predicted more prevalent and increasing toddler symptoms associated with affective, hyperactive, and oppositional defiant disorders. Thus, the verbal hostility component of authoritarian parenting could serve as a major intergenerational pathway between maternal trauma and early child symptoms.     

Action-effect binding by observational learning

The acquisition of bidirectional action–effect associations plays a central role in the ability to intentionally control actions. Humans learn about actions not only through active experience, but also through observing the actions of others. In Experiment 1, we examined whether action–effect associations can be acquired by observational learning. To this end, participants observed how a model repeatedly pressed two buttons during an observation phase. Each of the buttonpresses led to a specific tone (action effect). In a subsequent test phase, the tones served as target stimuli to which the participants had to respond with buttonpresses. Reaction times were shorter if the stimulus–response mapping in the test phase was compatible with the action–effect association in the observation phase. Experiment 2 excluded the possibility that the impact of perceived action effects on own actions was driven merely by an association of spatial features with the particular tones. Furthermore, we demonstrated that the presence of an agent is necessary to acquire novel action–effect associations through observation. Altogether, the study provides evidence for the claim that bidirectional action–effect associations can be acquired by observational learning. Our findings are discussed in the context of the idea that the acquisition of action–effect associations through observation is an important cognitive mechanism subserving the human ability for social learning.     

Rates of responding measured by continuous recording in applied behavioral research

There is no published source that can inform behavioral measurement research about typical response rates measured by continuous recording in applied behavior analysis. The present study was designed to determine the distribution of data on rate of responding reported across a recent 10‐volume (1998–2007) sample of research articles from the Journal of Applied Behavior Analysis. Rate of responding was measured for 20 553 datapoints in 360 sets of data (one participant in one graph) presented in 60 research articles. The majority of datapoints showed response rates of less than 1.0 response per minute, with 28.3% at zero. The highest rate reported was 104.5 responses per minute. The maximum response rate in datasets was more than 1.0 response per minute in 96.7% of datasets, indicating that continuous recording has been employed in research in which a relatively high rate of responding was recorded at some time during the study. The data from this report will assist researchers to determine empirically the representativeness of response rates in studies of measurement in applied behavior analysis.

Affective mediators of intergroup contact: a three-wave longitudinal study in South Africa

Intergroup contact (especially cross-group friendship) is firmly established as a powerful strategy for combating group-based prejudice (Pettigrew & Tropp, 2006). Great advances have been made in understanding how contact reduces prejudice (Brown & Hewstone, 2005), highlighting the importance of affective mediators (Pettigrew & Tropp, 2008). The present study, a 3-wave longitudinal study undertaken among minority-status Colored high school children in South Africa (N = 465), explored the full mediation of the effects of cross-group friendships on positive outgroup attitudes, perceived outgroup variability, and negative action tendencies via positive (affective empathy) and negative (intergroup anxiety) affective mediators simultaneously. The target group was the majority-status White South African outgroup. As predicted, a bidirectional model described the relationship between contact, mediators, and prejudice significantly better over time than either autoregressive or unidirectional longitudinal models. However, full longitudinal mediation was only found in the direction from Time 1 contact to Time 3 prejudice (via Time 2 mediators), supporting the underlying tenet of the contact hypothesis. Specifically, cross-group friendships were positively associated with positive outgroup attitudes (via affective empathy) and perceived outgroup variability (via intergroup anxiety and affective empathy) and were negatively associated with negative action tendencies (via affective empathy). Following Pettigrew and Tropp (2008), we compared two alternative hypotheses regarding the relationship between intergroup anxiety and affective empathy over time. Time 1 intergroup anxiety was indirectly negatively associated with Time 3 affective empathy, via Time 2 cross-group friendships. We discuss the theoretical and empirical contributions of this study and make suggestions for future research.     

Referential competence is associated with motivational congruence

[Schultheiss, 2001] and [Schultheiss, 2008] hypothesized that referential competence (RC) - stable individual differences in the ability to quickly name nonverbally represented information - should predict congruence between implicit and explicit motives. We tested this hypothesis using a color-naming task to assess RC, picture-story measures of implicit motives, and self-report measures of participants’ motivational values and goals. Study 1 showed that the RC measure captures a stable individual difference by test-retest and internal consistency criteria. Studies 2 and 3 provided correlational evidence for the hypothesized association between RC and measures of between- and within-individual motivational congruence. Study 4 showed that in the absence of situationally induced referential processing, RC predicts preferences for motive-congruent goals.     

Committed dis(s)idents: participation in radical collective action fosters disidentification with the broader in-group but enhances political identification

The present research examined the hypothesis that participation in radical, but not moderate, action results in disidentification from the broader in-group. Study 1 (N = 98) was a longitudinal study conducted in the context of student protests against tuition fees in Germany and confirmed that participation in radical collective action results in disidentification with the broader in-group (students) whereas participation in moderate collective action does not. Both types of action increased politicized identification. Study 2 (N = 175) manipulated the normativeness of different types of imagined collective actions in the same context and replicated this disidentification effect for radical actions, but only when this action mismatched the broader in-group's norms. This study also indicated that these effects were partially mediated by perceived lack of solidarity and perceived lack of commitment to the cause among the broader in-group. The implications of these findings for understanding radicalization within social movements are discussed.
