The influence of state and trait energy on self-regulatory behaviour

Holmqvist, Maxine Elisabeth 12 January 2009
Self-regulation is a highly adaptive process that enables goal-directed behaviour; however, individuals often fail to self-regulate successfully. Failures of self-regulation in the domain of health may be particularly harmful especially for those with chronic diseases. The Energy Model articulated by Baumeister and colleagues proposes that all acts of self-regulation rely on a single, finite energy resource. Thus, one possible explanation for self-regulation failure is insufficient energy. In the current research, four studies examine the relationship between the construct of energy, which can manifest in state or trait form, and self-regulatory success. Past research has demonstrated that individuals who perform two sequential tasks requiring self-regulation perform worse on the second task (the self-regulatory fatigue effect). The Energy Model proposes that this performance decrement can be explained by energy depletion. If this is true, then state energy should mediate the self-regulatory fatigue effect. A series of three experimental studies (studies 1-3) were designed to test this hypothesis. In Study 1, participants were randomly assigned to a gaze regulation task or to a no-regulation control group (as in Schmeichel et. al, 2003) before they watched a brief video clip. Following this first task, all participants worked on a second self-regulatory task (solving anagrams). Persistence and performance on this second task were the dependent measures and energy was measured before and after the initial video task. Contrary to the predictions of the Energy Model, the self-regulatory fatigue effect was not replicated in this study and so the mediating potential of energy could not be tested. However, ratings of task difficulty and effort suggested that individuals in the gaze regulation condition did not find this task to be very challenging. Accordingly, a second study was designed that added an additional level of self-regulatory demand by asking participants to rehearse a 7-digit number during the video clip (memory regulation). When this was crossed with the gaze regulation manipulation, four conditions were created: no regulation, gaze regulation only, memory regulation only and memory + gaze regulation. Study 2 then followed the same approximate procedure as Study 1, with individuals randomly assigned to one of the four conditions. The results of this study were consistent with Study 1 in that the self-regulatory fatigue effect was not replicated. However, the manipulation check suggested that some of the participants in the gaze regulation conditions may not have adhered to experimental instructions and the conditions may have differed in the degree to which they were enjoyable and interesting to participants. Accordingly, a third study used an eye-tracker to assess self-regulation during the video task and evaluated aspects of task engagement. Study 3 followed the same procedures as Study 2. Eye-tracker data verified significant differences between the groups in terms of self-regulation during the initial video task; however, there were no other significant between group differences. Taken together, these 3 studies indicate that the self-regulatory fatigue effect may be less robust than previous research would suggest. An unexpected finding was the high degree of variability in the energy measures, which implied that individual differences in energy may be important to consider. Accordingly, Study 4 prospectively examined the role of dispositional energy in the self-regulation of diet and exercise behaviour by testing whether energy moderated intention-behaviour concordance in a sample of individuals newly diagnosed with Type 2 diabetes. This study demonstrated that energy predicted future exercise behaviour in this sample and provided some preliminary support for the hypothesis that individuals with higher levels of dispositional energy may show more intention-behaviour concordance than those with lower levels of dispositional energy. Overall, these 4 studies provide some tentative support for the role of dispositional energy in the implementation of health behaviour, but do not support the Energy Models predictions regarding self-regulatory fatigue.

Walk the line: Balancing conflicting goals through tension systems

Chua, Sook Ning January 2008 (has links)
Although our society esteems individuals who achieve it all, the 24-hour day and our limited resources means that attaining multiple goals is a difficult undertaking. This research draws upon Lewin’s theorizing on goal conflict and goal interruption to predict how individuals balance important conflicting goals. We predict that when an individual experiences goal conflict, the individual will prioritize his/her goals by moving towards one goal. Counter-intuitively however, we also hypothesize that this movement away from the competing goal will facilitate its pursuit, thus enabling goal balancing. We suggest that when the individual moves towards goal A, the competing goal B’s progress is interrupted. The psychological incompletion of goal B causes its state of tension to persist and consequently the individual feels the need to resume the goal. Accordingly, we expect affective and motivational consequences to this conflict-induced goal interruption. We found support for our hypotheses in 2 experiments that examined the conflict between academic and relationship goals. When individuals who are high in chronic relationship commitment experience goal conflict, they reported higher state relationship commitment (Chapter 2 and 3) and lower academic commitment (Chapter 3), relative to individuals who are low in chronic relationship commitment. However, in support of our conflict-induced goal interruption hypothesis, they also report lower partner affect (Chapter 2) and better performance in an academic-related task (Chapter 3).

The effect of income inequality on individual ideation-based creativity via self-regulation

Morris, Kevin 12 September 2015 (has links)
The purpose of this research is to examine the impact of income inequality on individual creativity. Specifically, it is hypothesized that an individual’s creative performance (via a remote associatives test) is affected negatively in a high income inequality condition. Theoretical research suggests that the mechanism that enables this is self-regulation. As such self-regulation is measured as a mediator in this relationship. Two online-panel experiments were designed and conducted to test these relationships. The results did not show significant results for the mediation relationship. Self-regulation does have a positive relationship with creative performance, and income inequality shows a negative relationship with creativity in some conditions, however there is no relationship between income inequality and self-regulation. This research develops the theoretical background for the relationship between income inequality, self-regulation, and creativity. It also provides some lessons-learned from an experimental mediation design with an independent variable that has multiple categorical variables. / October 2015

Motivational Differences in Aiming for Wide or Narrow Goals

Xu, Zhaoxia January 2014 (has links)
Goal setting theory has consistently found that high and specific goals lead to better performance than low and vague goals do. However, the independent effect of each of these two dimensions, difficulty and specificity, on performance is less clear. Although goal difficulty has been shown to affect performance level independent of goal specificity, evidence for an independent effect of goal specificity is mixed. In the current research, we introduce a moderator, regulatory focus, of the relationship between goal specificity and performance level. Specifically, we hypothesized that people in a promotion focus would be more motivated by aiming for wider goals that have a higher possibility of success and therefore fit an eager-approach strategy, while people in a prevention focus would be more motivated by aiming for narrower goals that have a small range of acceptable outcomes and therefore fit a vigilant-avoidance strategy. We examined this hypothesis with different hypothetical scenarios that manipulated goal width (wide versus narrow) with numerical ranges (Study 1) and visually with a bar graph (Study 2), and with different behavioural tasks that manipulated goal width in a saving strategies task (Study 3) and an anagram task (Study 4a, 4b). The findings revealed promising trends that were consistent with our hypothesis across all studies.

To stop or not to stop? - Investigating the differential effects of two self-control stategies on self-regulatory resource depletion

Li, Alex Sai Hoi January 2010 (has links)
PhD / Self-regulation is a vital function to humanity, and is an important factor in the dominant paradigm of consumer research, whereby consumer decisions are characterised by the battle between long- and short-term interests. The current research examined the relative effectiveness of two self-regulatory strategies: stopping an already-commenced consumption episode, or to not commence one at all. Traditional economic theories, including the principle of diminishing marginal utility, would predict that not starting is harder to accomplish; whereas a proposal by Thaler (1983) suggests that not starting is in fact the optimal strategy. Two studies were conducted whereby participants were asked to either perform a less-favoured task and resist from starting a more-favoured one (Not Start), or to cease performing a more-favoured task to complete the less-favoured task (Stop). Study 1 found that Stop was more difficult than Not Start, which tentatively supported Thaler’s argument; however there was an explanation which could not be ruled out, namely the psychological distance of the anticipated second task. Study 2 addressed this issue by manipulating that factor by incorporating it into the experimental design. It was found that Not Start became as depleting as Stop when psychological distance of the second task was reduced. This research contributed to the literature by establishing a boundary condition upon the strength model of self-regulatory resource depletion, and adds to the discussion on the descriptive validity of the principle of diminishing marginal utility.

Adapting Leader Behaviors to Achieve Follower Effectiveness: A Mindful Approach to Situational Leadership

January 2015 (has links)
abstract: This study develops a theoretical model that explains how leaders come to adapt their leadership behaviors to achieve follower effectiveness. Mindfulness theory suggests that mindful individuals are better able to engage in self-regulation and I consider empathy, response flexibility, and emotional regulation as three self-regulatory processes in particular which likely impact the leader-follower relationship. I suggest that leaders who have the ability to self-regulate in these three ways will be better able to engage in leadership behavior characterized by adapting or flexing the specific types of leadership they demonstrate according to the needs of the situation and what their followers most require at a given time to perform at their best. When followers receive the type of situationally-appropriate support in the form of leader behavior, they are more effective (e.g. have higher job performance and extra-role performance). I validate a new trait and state measure of workplace mindfulness with multiple samples and utilize this new scale to collect data from leaders and followers from a government organization to test the theoretical relationships proposed in this study. I utilize an experience sampling methodology (ESM) design over 10 days to investigate the within-leader variation among variables in the study given theory suggesting the dynamic nature of the mindfulness, self-regulation, and situational leadership constructs which may not adequately be captured when data are collected at one point in time. Finally, I introduce organizational constraints as a moderator of the relationship between leader mindfulness and leader self- regulation in order to understand how stressors and strains outside the control of a leader may overload a leader’s ability to ultimately self-regulate his/her behavior. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2015

Associations between musical experience and self-regulation: Cognitive, emotional, and physiological perspectives

January 2021 (has links)
archives@tulane.edu / Musical experience is associated with a host of benefits to self-regulatory processes across multiple psychological domains. The purpose of the studies presented in this dissertation was to examine relationships between musical experience and cognitive, emotional, and physiological self-regulation. Cognitive regulation was measured with tasks of executive functions; emotional regulation was measured by self-efficacy, incidences of mental illness, depressive symptoms, and perceived chronic stress; and physiological regulation was measured by cortisol levels in response to an acute psychological stressor. Findings on cognitive regulation showed that enrollment in music programming during childhood was associated with enhanced working memory maintenance and updating, and musical experience in early adulthood was associated with enhanced cognitive flexibility. Among musically experienced adults, the ability to create a four-part harmonization was also associated with enhanced cognitive flexibility. With respect to emotional regulation, continued enrollment in music programming was associated with higher regulatory self-efficacy in children, and musically trained adults demonstrated lower incidences of mental illness, depressive symptoms, and perceived chronic stress. No physiological differences were found in acute cortisol reactivity between musicians and non-musicians, despite lower levels of perceived chronic stress in musicians. Taken together, these results suggest that cognitive and emotional self- regulation are impacted by music training, but not physiological regulation. However, divergent findings may depend on the type of musical experience measured, and the age of musical engagement. / 1 / Jenna Winston
