Repeated Self-Regulation and Asymmetric Hemispheric Activation

Numerous recent studies have investigated repeated self-regulation to uncover the processes involved in self-regulatory behavior over time. Results from most of these studies are consistent with a depletion process in which self-regulatory effectiveness declines over time due to resource depletion. The present research examined an additional factor that may also be involved in repeated self-regulatory exertion, namely, differential hemispheric activation. Five studies examined this issue, focusing on self-control tasks requiring avoidance or vigilance. Studies 1 to 3 indicated that these tasks resulted in greater relative right hemispheric activation. Studies 4 and 5 indicated that, consistent with this pattern of differential activation, initial vigilance self-control resulted in better subsequent performance on a spatial self-regulatory task but worse performance on a verbal self-regulatory task. These findings provide additional insight into the dynamics of self-regulatory behavior across tasks, suggesting the combination of tasks examined may influence the pattern of results obtained.     

Evolution of communication in perfect and imperfect worlds

We extend previous work on cooperation to some related questions regarding the evolution of simple forms of communication. The evolution of cooperation within the iterated Prisoner's Dilemma has been shown to follow different patterns, with significantly different outcomes, depending on whether the features of the model are classically perfect or stochastically imperfect (Axelrod, 1980a,b, 1984, 1985; Axelrod and Hamilton, 1981; Nowak and Sigmund, 1990, 1992; Sigmund, 1993). Our results here show that the same holds for communication. Within a simple model, the evolution of communication seems to require a stochastically imperfect world.     

Psychotherapy as Moral Encounter: A Crisis of Modern Conscience

Psychotherapy can no longer be understood as a morally neutral or value-free practice. Many have argued that psychology is implicitly and inevitably laden with moral assumptions and has a significant impact on the moral and ethical fabric of its clients and surrounding society (Browning 1987; Doherty 1995; Dueck and Reimer 2003; Kelly and Strupp 1992; Rieff 1987, 2006). In this work, the authors highlight the profound identity crises within the field of psychology around the place of morality/ethics in its theories and practices. Chronicling some of the shifts between modern and postmodern theory will allow for a meaningful engagement with this issue. The postmodern shifts in the field have left clinicians ideologically hampered in their ability to attend to the moral dimensions of their clients’ lives. In conclusion, the authors posit a virtue ethics and consider avenues of holistically and meaningfully infusing clinical practice with moral sensibilities.     

Personal mastery predicts pain,stress, fatigue,and blood pressure in adults with rheumatoid arthritis

Among individuals with rheumatoid arthritis (RA), stress-associated disease flare can severely impact well-being. Psychological factors such as personal mastery may buffer an individual from the negative effects of those flares. We tested the hypothesis that a high sense of personal mastery would prospectively predict stress reactivity. Measures of pain, perceived stress, fatigue, and mean arterial pressure (MAP) were collected before, during, and after two interpersonal stressors conducted on 73 individuals with RA. Factor analysis of the personal mastery scale yielded two independent factors: a 5-item “fatalism” component and a 2-item “control” component. Individuals with high fatalism scores reported overall greater joint pain at baseline and those scoring high on control exhibited lower MAP, and reported less stress and fatigue at baseline. After controlling for baseline differences, those high in control exhibited greater MAP increase during stress, and less drop in pain when compared to those low in control. These results suggest that individuals high in control may be more susceptible to the effects of acute stress; however, the overall beneficial aspects of high control outweigh the acute negative effects. Personal mastery may play a role in the experience of pain, stress, and fatigue for people with RA.     

Spontaneous and experimentally induced action planning and coping planning for physical activity: A meta-analysis

ObjectivesThe main objective of this review was to provide summary effects for spontaneous and experimentally induced action planning (AP) and coping planning (CP) for physical activity (PA). These summary effects were then used to test key theoretical postulates using meta-analytic path analysis, and examine possible boundary conditions via moderation analyses.DesignThis review employed a quantitative research synthesis design.MethodUsing the method of Lipsey and Wilson (2001), fixed- and random-effects meta-analysis was performed on over 150 effect sizes from 23 correlational and 21 experimental studies. The method of Viswesvaran and Ones (1995) was used to test two mediation models using the correlational meta-analytic data. Group comparisons and meta-regression were used to test moderation.ResultsAmong the correlational studies, findings indicated a medium-to-large summary effect of spontaneous AP (φ = .41) and CP (φ = .38) on PA. Among the experimental studies, results revealed a small-to-medium summary effect (φ = .24) when comparing all experimental conditions versus all controls and a medium-to-large summary effect (φ = .37) when comparing purely planning conditions versus neutral controls. Support was found for AP and CP as partial mediators in the relation between intention and PA. Numerous significant moderators emerged.ConclusionThis review offers the first meta-analytic estimates of both spontaneous and experimentally induced AP and CP for PA, while supporting the role of both spontaneous AP and CP as mediators in both a multiple and sequential mediation model. Relevant moderators will serve to inform future research in this area.     

Can't See the Forest for the Trees? The Effect of Media Multitasking on Cognitive Processing Style

Media multitasking represents an important aspect of the recent evolution in media consumption habits. While some experimental research exists, it has primarily focused on the detrimental effects of multitasking on task performance. We go a step further by examining the impact of media multitasking on information processing style. Study I demonstrates that media multitasking, compared to sequential media consumption, leads to a more local perceptual processing style. Furthermore, the frequency of media switching predicts the level of perceptual processing. Study II extends these findings by showing that media multitasking also affects conceptual processing style. Specifically, media multitasking leads to lower-level (or more concrete) construal of behaviors in a subsequent task. It further shows that conceptual rather than visual switching between media drives the observed differences in conceptual processing. These findings suggest that, as a growing phenomenon, media multitasking behavior may substantially alter the way media viewers process media content.     

From goal motivation to goal progress: the mediating role of coping in the Self-Concordance Model

Abstract

The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the “inception-to-attainment” goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.
