Condition B

The present study examined the effects of a changeover delay (COD) on the choice between smaller, shorter delayed reinforcement and larger, longer delayed reinforcement in a complex concurrent-chains schedule. Four pigeons were exposed to three conditions in an ABA or BAB reversal design. A COD of 2 seconds was included in the initial links during condition B. The concurrent-chains schedule had identical variable-interval schedules in the initial links and different delays and magnitudes of reinforcement that were programmed according to a fixed-ratio 10 (FR10) schedule in the terminal links. Each experimental condition lasted for two long sessions and five short sessions. Changeover rates were lower, and preference for the larger, longer delayed reinforcer was more pronounced during conditions with the programmed 2-second COD. The analysis of initial pauses and running rates during the FR10 schedules of the terminal links revealed no systematic effects of the COD on behavior in the terminal links. The COD had similar effects on choice performance in this modified concurrent-chain procedure as on simple concurrent performance.Keywords: Choice behavior, concurrent-chains, COD, self-control paradigm, pigeons.

Signal Presentation

Averaged auditory evoked responses to 1000-Hz 20-msec tone bursts were obtained from normal-hearing adults under two different intersignal interval schedules: (1) a fixed-interval schedule with 2-sec intersignal intervals, and (2) a variable-interval schedule of intersignal intervals ranging randomly from 1.0 sec to 4.5 sec with a mean of 2 sec. Peak-to-peak amplitudes (N 1 — P 2 ) as well as latencies of components P 1 , N 1 , P 2 , and N 2 were compared under the two different conditions of intersignal interval. No consistent or significant differences between variable- and fixed-interval schedules were found in the averaged responses to signals of either 20 dB SL or 50 dB SL. Neither were there significant schedule differences when 35 or 70 epochs were averaged per response. There were, however, significant effects due to signal amplitude and to the number of epochs averaged per response. Response amplitude increased and response latency decreased with sensation level of the tone burst.

Systematische Übersicht

Hintergrund: Verhaltenstherapeutische Behandlungen zum selbstkontrollierten Trinken (KT) wurden in den letzten 50 Jahren vielfältig erforscht. Eine aktuelle Übersicht über den gegenwärtigen Status dieses Ansatzes liegt nicht vor. Fragestellung: Es wird ein systematischer Überblick über die Konzept- und Forschungsgeschichte des KT (Definition, theoretische Wurzeln, Behandlungsmethoden), Wirksamkeit von KT-Behandlung (inkl. Prognosefaktoren) sowie Implementierung von KT in das Behandlungssystem (Akzeptanz und Verbreitung) vorgenommen. Methodik: Gemäß den PRISMA Richtlinien wurde in den Datenbanken PsycINFO, Medline und Psyndex nach psychologischen Behandlungen zum selbstkontrollierten Alkoholkonsum bei Menschen mit klinisch relevanten Alkoholproblemen recherchiert und 676 einschlägige Beiträge identifiziert. Ergebnisse: KT wird als regelgeleitet-planvoller Alkoholkonsum definiert. Seine theoretischen Wurzeln reichen von Lerntheorien bis zur Psychologie der Selbstregulation. In der Behandlung haben Behavioral Self-Control Trainings frühere Methoden (z. B. aversive Konditionierung, Kontingenzmanagement und Reizexposition) abgelöst. Einzel und Gruppenbehandlungen sowie Selbsthilfemanuale zum KT erweisen sich über das gesamte Spektrum des problematischen Alkoholkonsums als kurz- und langfristig wirksam zur Reduktion des Alkoholkonsums und alkoholassoziierter Probleme wie auch zur Förderung des Übergangs zur Abstinenz. Prognostisch bedeutsam sind v. a. der Zielentscheid des Patienten pro KT und seine Zuversicht in die Realisierbarkeit von KT. Akzeptanz und Verbreitung von KT haben in den letzten Jahrzehnten zugenommen und variieren u. a. länderspezifisch. Schlussfolgerungen: Angesichts der Wirksamkeit von KT-Behandlungen sowie gesundheitspolitischer, ethischer, therapeutischer und ökonomischer Überlegungen sollten Reduktionsbehandlungen gleichrangig neben Abstinenzbehandlungen in ein zieloffen ausgerichtetes Behandlungssystem integriert werden.

Abstract. The neurovisceral integration model proposes that different forms of self-regulation, including the emotional suppression, are characterized by the activation of neural network whose workings are also reflected in respiratory sinus arrhythmia (RSA). However, most of the previous studies failed to observe theoretically expected increases in RSA during emotional suppression. Even when such effects were observed, it was not clear whether they resulted from specific task demands, a decrease in muscle activity, or they were the consequence of more specific self-control processes. We investigated the relation between habitual or trait-like suppression, spontaneous, and instructed suppression with changes in RSA during negative emotion experience. A modest positive correlation between spontaneous situational and habitual suppression was observed across two experimental tasks. Furthermore, the results showed greater RSA increase among participants who experienced higher negative affect (NA) increase and reported higher spontaneous suppression than among those with higher NA increase and lower spontaneous suppression. Importantly, this effect was independent from the habitual suppression and observable facial expressions. The results of the additional task based on experimental manipulation, rather than spontaneous use of situational suppression, indicated a similar relation between suppression and RSA. Our results consistently demonstrate that emotional suppression, especially its self-regulation component, is followed by the increase in parasympathetic activity.

Low Self Control

The study was part of the Jyväskylä Longitudinal Study of Personality and Social Development, underway since 1968, in which children's low self-control of emotions was studied using teacher ratings at age 8 in terms of inattentiveness, shifting moods, aggression, and anxiety. The study was based on data from 112 women and 112 men who participated in the previous data collections at ages 8, 27, and 36. At age 27, the participants had been assessed in Neuroticism (N) using the Eysenck Personality Questionnaire , and at age 36 they filled in several inventories measuring, among others, conscious and active attempts to repair negative emotions in a more positive direction as well as physical symptoms. The present study used structural equation modeling to test the hypothesis that personality characteristics indicating low self-control of emotions at ages 8 and 27 are antecedents of self-reported physical symptoms at age 36; and that this relationship is indirect, mediated by attempts to repair negative emotions in a more positive direction. The findings showed, albeit for men only, that inattentiveness at age 8 was positively related to self-reported physical symptoms at age 36 via high N at age 27 and low attempts to repair negative emotions at age 36. Additionally, N at age 27 was directly linked to self-reported physical symptoms at age 36. The mediation of an active attempt to repair negative emotions was not found for women. Correlations revealed, however, that shifting moods and aggression in girls were antecedents of self-reported physical symptoms in adulthood, particularly, pain and fatigue.
