Oral drug self-administration in rhesus monkeys: interactions between drug amount and fixed-ratio size.

During daily 3-hr sessions, 5 rhesus monkeys drank drug solutions and water that were concurrently available. The drug solutions were: 1 milligram per milliliter (mg/mL) pentobarbital (2 monkeys), 1 mg/mL pentobarbital plus 0.5% ethanol (1 monkey), 1 mg/mL pentobarbital plus 1% ethanol (1 monkey), and 8% ethanol (1 monkey). The drug solution and water were available under identical two-component tandem fixed-ratio continuous-reinforcement N schedules. Two variables were manipulated: the size of the fixed-ratio component and the number of liquid deliveries (N) in the second component. Deliveries of the drug solution maintained higher rates of responding than did deliveries of the drug vehicle, water. The number of drug deliveries per session increased with increases in the number of deliveries per fixed ratio and decreased with increases in fixed-ratio size. Analysis of the results in terms of the proportion of deliveries to responses showed that the number of drug deliveries per session was directly related to the size of this quotient. Finally, when fixed-ratio size was repeatedly doubled, the following orderly relationship emerged: The greater the number of available drug deliveries per fixed ratio, the less was the percent decrease in the number of fixed ratios completed per session. It was concluded that increases in the number of liquid deliveries per fixed ratio resulted in increases in reinforcing efficacy.

Doing as if: The histrionic self-presentation style

The histrionic self-presentation style is introduced as a concept that describes specific individual differences in self-presentation, namely, performing explicit As-If-behaviors in everyday interactions. The As-If-Scale (AIS), a trait measure of histrionic self-presentation, shows good internal consistency and test–retest reliability as well as convergent and discriminant validity in several samples. Construct validation involved determining relations between the AIS and the Big Five, histrionic role concepts, motives, competencies, humor and ambivalence. Furthermore, the AIS yielded incremental validity in predicting behaviors related to histrionic self-presentation over and above the self-monitoring construct. The possible impact of the histrionic style for research on self-presentation and other fields is discussed. It is argued that histrionic phenomena are pervasive within many facets of our western culture and therefore deserve further examination.     

Analysis of the Mediating Effect of Personal-Psychological Variables on the Relationship Between Socioeconomic Status and Political Participation: A Structural Equations Framework

The goal of this research was to test whether the relationship between socioeconomic status and political participation is direct or mediated by personal variables such as self-esteem, locus of control, and political efficacy, and to detect how such a mediating process might operate if it exists. Two forms of participation, namely active political participation and the more passive psychological involvement of citizens in the democratic process, were treated as separate but related facets of participation. Four competing models were advanced and tested. The data were collected from 434 citizens in the north of Israel who were interviewed by questionnaire. The analysis was performed by structural equations modeling with LISREL VIII. The findings show that the relationship between socioeconomic status and political participation can be better understood as being mediated by personal variables rather than direct. This is demonstrated by the many nonsignificant paths in the direct model. The findings also reveal that active political participation and psychological involvement are distinct but related constructs, where involvement leads to active participation. In addition, all research variables were related more strongly to psychological involvement than to active political participation. The findings are discussed in terms of their implications for future research on political participation.     

Should I just listen to you or change your mind too? Target's perceived efficacy of agents’ interpersonal affect improvement strategies

People shape and influence others’ emotions every day. If these attempts are perceived as successful, they may have a positive effect on people's relationships and well-being. Across two studies, targets’ perceived efficacy of regulation strategies to improve their sadness and anxiety/stress has been investigated. In Study 1, participants (n = 120) were provided with two scenarios depicting sadness and anxiety/stress and asked to imagine themselves in these situations. Afterwards, they were provided with different regulation strategies and asked to rate their perceived efficacy to downregulate their sadness and anxiety. In Study 2, participants (n = 120) were asked to describe a situation where they felt sad and another one where they felt anxious. They were then provided with strategies aimed at reducing their sadness and anxiety. Results from both studies showed that whereas for sadness higher perceived efficacy was predicted by affective engagement, for anxiety/stress was predicted by cognitive engagement.
