People everywhere strive for an ideal view of the self, but the conception of “ideal” differs importantly across cultures. In Western societies, the ideal self entails the possession of high self-esteem, whereas in East Asian cultures the ideal self entails maintenance of “face,” or successful performance of social roles and obligations. Within each cultural context, aspirations for an ideal self are facilitated by a network of psychological processes. One such psychological process is approach and avoidance motivations: approach motivation is useful for Westerners’ pursuit of high self-esteem whereas avoidance motivation is useful for East Asians’ concerns for face maintenance. Review of prior research renders support to this theorizing. Because approach and avoidance motivations are fundamental psychological processes, cross-cultural research on this topic is a great venue for investigating the ways in which culture shapes psychological processes. This dissertation examines the implication of cultural differences in approach and avoidance motivations in two domains. Studies 1 and 2 investigated the motivational consequences of a fit between culturally encouraged motivation and focus of self-regulation that a task at hand calls for. In comparisons of Canadians and Japanese, these studies found that individuals’ motivation for a task is enhanced when culturally encouraged motivation matched with focus of self-regulation required for the task. The second set of studies (Study 3 and 4) examined cognitive consequences of approach-avoidance motivation cultural difference. These studies found that a type of information that people are attuned to differs as a function of cultural differences in approach-avoidance motivations. Implications of the findings and future directions are discussed.

Enemyship is an important but understudied interpersonal phenomenon. Prior research on this topic has focused on enemyship's cognitive, control-maintenance function following a threat. The present studies advance theory and research by showing the role of emotion, particularly anger, in this process. Using appraisal theory as a framework, we draw on recent research into approach and avoidance motivational dynamics during threat We propose an interaction between anxiety-inducing threat and enemy-directed anger on perceptions of control and certainty, and motivation. More specifically, we expect that when an anxiety-inducing threat is present, perceptions of control and certainty will be significantly higher when enemy-directed anger is also present than when it is not Additionally, we sought to demonstrate the consequences of these processes for motivation. Perhaps counterintuitively, we propose that individuals who experience anger at an enemy following an anxiety-inducing control threat will experience a boost in motivation, an effect mediated by perceptions of control and certainty. We find support for our moderated mediation model across three studies with undergraduate and working adults (Total N = 673).

Research on healthy eating motivation has shown that people who are autonomously motivated tend to engage in healthier eating behaviours than people with controlled forms of motivation (Ng et al., 2012; Verstuyf et al., 2012). However, healthy eating requires both trying to eat healthy foods (i.e., approach goals) and trying to avoid unhealthy foods (i.e., avoidance goals), and previous research on the association between motivation and approach-avoidance eating goals is mixed (Harrison et al., 2011; Otis & Pelletier, 2008). In the current study, we explored the relationship between motivation and approach-avoidance goals using a 21-day daily diary design. Our findings indicated that approach goals were more difficult than avoidance goals and that higher relative autonomous motivation was associated with greater approach goal success, but not avoidance goal success. We also investigated the relationship between goal specificity, the temporal scope of approach-avoidance goals, and goal success/failure. Our findings are consistent with previous research on motivation and goal difficulty (Aitken et al., 2016; Green-Demers et al., 1997), but our approach-avoidance goal difficulty findings warrant further investigation. / Graduate / 2018-06-11

Gemäß 2-Prozess-Modellen der Abhängigkeit resultiert die Reaktion auf suchtassoziierte Reize aus der Interaktion zweier in Verbindung stehender, aber unabhängig voneinander arbeitender Systeme: Aus dem Zusammenspiel eines dominierenden Implizitsystems und eines geschwächten Explizitsystems ergeben sich starke Annäherungstendenzen, die immer wieder zum Konsum der Droge führen. Den genannten Systemen können eigene aber überlappend arbeitende neuronale Schaltkreise zugeordnet werden. Als Anteil des Implizitsystems generieren Impulse des Striatums Annäherungstendenzen. Gegenspieler hierzu ist der Bereich der Amygdala, hier kann Vermeidungs- und Abwendungsverhalten gegenüber präsentierten Stimuli entstehen. Beiden übergeordnet befähigt der präfrontale Cortex zu einer bewussten Entscheidungsfindung und Verhaltenskontrolle (Triadic Modell). Indirekte Mess-methoden wie die Approach-Avoidance Task (AAT) ermöglichen über die Analyse des gezeigten Verhaltens die Erfassung der vorherrschenden Assoziationen zwischen emotionaler Stimuluswertigkeit und aufkommender Verhaltenstendenz des impulsiven Systems. Grundlage der AAT ist es dabei, dass prinzipiell als positiv bewertete Stimuli vorrangig mit Annäherungs-verhalten, Stimuli mit Negativbewertung dagegen eher mit Vermeidungs-verhalten verknüpft werden. Je nach Aufgabenstellung werden Reizvalenz und geforderte motorische Reaktion unterschiedlich kombiniert. So ergeben sich kompatible bzw. inkompatible Kombinationen zwischen dargebotenem Reiz, geforderter Reaktion (Annäherung vs. Vermeidung) und empfundener Assoziation (positiv vs. negativ). Bei Kompatibilität werden schnellere Reaktionen mit niedrigerer Fehlerrate gezeigt als bei inkompatibler Aufgaben-stellung. Dies lässt auf die vorliegenden Verhaltenstendenzen schließen. In der vorliegenden Arbeit entscheidet der Faktor „Gruppe“ (alkoholabhängige Pro-banden bzw. gesunde Kontrollpersonen) über Kompatibilität bzw. Inkompatibilität der Kombination aus Reiz (alkoholassoziierter bzw. nicht-alkoholassoziierter Stimulus) und Verhalten (Annäherung bzw. Vermeidung). Ziel war es nun die postulierten Annäherungstendenzen gegenüber alkohol-assoziierten Reizen auf Verhaltensebene mittels AAT zu erfassen. Gleichzeitig wurde mittels Nahinfrarot-Spektroskopie (NIRS) die Aktivität der beteiligten kortikalen Strukturen des dorsolateralen Präfrontalcortex (DLPFC), des Orbito-frontalcortex (OFC) sowie des dorsalen fronto-medianen Cortex (DFMC) gemessen und zwischen alkoholabhängigen und gesunden Probanden ver-glichen. Bezüglich der gemessenen Reaktionszeiten ergaben sich wie erwartet bei dem untersuchten Patientenkollektiv Annäherungstendenzen gegenüber alkoholassoziierten Stimuli. Gegenüber nicht-alkoholassoziierten Produkt-bildern waren Vermeidungstendenzen erkennbar. Die Auswertungen der Kontrollgruppe ergaben genau umgekehrte Resultate. Identische Ergebnisse ließen sich für beide Gruppen bei Betrachtung der mittels NIRS gemessenen Hirnaktivität des OFC beschreiben. Diese Ergebnisse werden im Rahmen einer Abhängigkeit als Resultat einer vermehrt positiven Bewertung suchtassoziierter Stimuli mit einem übermäßigen Ansprechen des Belohnungszentrums diskutiert. Unabhängig der Gruppenzugehörigkeit konnten im Bereich des DLPFC durch eine stärkere kortikale Aktivierung bei Vermeidung im Vergleich zur Annäherung der alkoholassoziierten Produktbilder Annäherungspräferenzen gegenüber alkoholischen Produktbildern nachgewiesen werden. Die fehlenden Gruppenunterschiede lassen sich eventuell durch die gegebenen Instruktionen mit Betonung des Bildinhaltes und einem dadurch erzeugten Bewusstsein für die Hypothesen des Experiments erklären. Außerdem bietet eine durch Alkoholabhängigkeit generell verminderte Aktivität des DLPFC einen möglichen Erklärungsansatz. Korrelationsanalysen zwischen DLPFC und OFC unter-stützen die Vorstellung des DLPFC als oberstes Kontrollgremium über sämtlichen dem Belohnungszentrum zuzuordnenden Hirnstrukturen. Ausblickend lässt sich die klinische Bedeutung der erhaltenen Resultate erörtern. Aktuelle Forschungsarbeiten verwenden die AAT im Rahmen eines Trainings zur Rückfallprävention. Durch viele Wiederholungen der inkompatiblen Reiz-Verhaltenskombination werden vorhandene Annäherungs-tendenzen abgeschwächt und Rückfälle vermieden. Offen bleibt die Erforschung der diesen Trainingserfolgen zugrundeliegenden Mechanismen sowie eine mögliche Eingrenzung der davon profitierenden Patientengruppen. / The function of the dorsolateral prefrontal cortex during the regulation of appetitive reaction tendencies in alcohol addiction

The present research tested whether and how regulatory focus as a motivational variable influences the ways in which people appraise, process, and react to events in romantic relationships. Regulatory focus theory distinguishes between (1) a prevention focus, which emphasizes the fulfillment of security needs, duties and obligations, and is associated with heightened sensitivity to aversive outcomes, and (2) a promotion focus, which emphasizes the fulfillment of nurturance needs, accomplishments and aspirations, and is associated with heightened sensitivity to rewarding outcomes. Based on regulatory focus theory, it was assumed that promotion and prevention focused people would appraise, react to, and process interpersonal events involving a romantic partner in different ways. In addition, it was expected that the distinct ways of experiencing such events are reflected in differences in relationship quality. Three studies using college student samples were conducted to test these notions. Evidence was found that individual differences in chronic prevention focus affect the ways in which people react to aversive events in relationships. No support was obtained for regulatory focus theory??s predictions regarding prevention focus processes in association with rewarding outcomes, and predictions related to the promotion focus system were also not supported. As expected, chronic promotion focus was related to higher relationship quality, and chronic prevention focus was associated with lower relationship quality. Implications and suggestions for future research are discussed.
