When goals loom darker: Goal ambivalence moderates the effect of goal proximity on goal-related motivation

This research extends previous work on the self-regulation of goal striving as well as effects of temporal and psychological distance on motivation. Borrowing from classic work on goal gradients and approach-avoidance conflicts, we predicted that the experience of ambivalence toward a personal goal moderates the extent to which feeling or being close to goal attainment affects motivation, such that greater proximity to the goal has a negative effect on motivation at higher levels of experienced goal ambivalence. We find evidence for the hypothesized effect across three studies examining different goals (pursuing a degree, running a half-marathon) with varying operationalizations of goal proximity (self-reported, manipulated, temporal) and motivation (goal commitment, intention strength). These results validate that classic concepts of motivation science such as goal gradients and approach-avoidance conflict are both relevant and applicable to the everyday pursuit of self-set personal goals.     

Body Experience After Liver Transplantation: A Body Grid Examination

Living with a donated organ raises not only clinical aspects, such as surgery risks and possible graft rejection, but also questions regarding the psychological integration of the donor organ and the recipient's body experience. Organ recipients need to cope with the transplantation and its impact on their bodies and lives. This study presents findings concerning the psychological outcome of liver recipients and their body experience after transplantation. The focus lies on the psychological integration of the liver by the recipients and on differences in the body experience between recipients of a living liver donation (LDLT) and a deceased donor donation (LTx). To study the subjective body experience and the donor-organ integration, we used the body grid, a modification of the repertory grid technique pioneered by Kelly (1955 Kelly, G.A. (1955). The psychology of personal constructs. New York, NY: Norton. [Google Scholar]). This technique allows both a quantitative and a qualitative research approach. We examined 22 liver recipients (12 LDLT; 10 LTx), matched for age, gender, years since transplantation, and type of liver disease. Additionally, quality of life data were collected using the Short Form-8 health survey (SF-8), along with sociodemographic data, including the current living situation, changes after transplantation, living donor data, and the donor-recipient relationship for the LDLT cases. Correlations between the SF-8 scores and the element distances were calculated. The results depict the recipients’ body experiences after liver transplantation, the psychological integration of the transplanted organ, and correlations between quality of life and organ integration. Differences between the LDLT and LTx group are discussed, as well as implications for improving the treatment and psychological support of the recipients.     

Risky choice with heuristics: reply to Birnbaum (2008), Johnson, Schulte-Mecklenbeck, and Willemsen (2008), and Rieger and Wang (2008)

E. Brandst?tter, G. Gigerenzer, and R. Hertwig (2006) showed that the priority heuristic matches or outperforms modifications of expected utility theory in predicting choice in 4 diverse problem sets. M. H. Birnbaum (2008) argued that sets exist in which the opposite is true. The authors agree--but stress that all choice strategies have regions of good and bad performance. The accuracy of various strategies systematically depends on choice difficulty, which the authors consider a triggering variable underlying strategy selection. Agreeing with E. J. Johnson, M. Schulte-Mecklenbeck, and M. C. Willemsen (2008) that process (not "as-if") models need to be formulated, the authors show how quantitative predictions can be derived and test them. Finally, they demonstrate that many of Birnbaum's and M. O. Rieger and M. Wang's (2008) case studies championing their preferred models involved biased tests in which the priority heuristic predicted data, whereas the parameterized models were fitted to the same data. The authors propose an adaptive toolbox approach of risky choice, according to which people first seek a no-conflict solution before resorting to conflict-resolving strategies such as the priority heuristic.     

Electrophysiological markers of visual dimension changes and response changes

In cross-dimensional visual search tasks, target discrimination is faster when the previous trial contained a target defined in the same visual dimension as the current trial. The dimension-weighting account (DWA; A. Found & H. J. Müller, 1996) explains this intertrial facilitation by assuming that visual dimensions are weighted at an early perceptual stage of processing. Recently, this view has been challenged by models claiming that intertrial facilitation effects are generated at later stages that follow attentional target selection (K. Mortier, J. Theeuwes, & P. A. Starreveld, 2005). To determine whether intertrial facilitation is generated at a perceptual stage, at the response selection stage, or both, the authors focused on specific event-related brain potential components (directly linkable to perceptual and response-related processing) during a compound search task. Visual dimension repetitions were mirrored by shorter latencies and enhanced amplitudes of the N2-posterior- contralateral, suggesting a facilitated allocation of attentional resources to the target. Response repetitions and changes systematically modulated the lateralized readiness potential amplitude, suggesting a benefit from residual activations of the previous trial biasing the correct response. Overall, the present findings strengthen the DWA by indicating a perceptual origin of dimension change costs in visual search.     

A high implicit affiliation motive does not always make you happy: A corresponding explicit motive and corresponding behavior are further needed

Satisfaction of the implicit affiliation motive is known to be positively related to emotional well-being, whereas the frustration of the implicit affiliation motive leads to impairment of well-being. In the present research we specified two conditions that are responsible for the satisfaction and frustration of the implicit motive. Referring to research on the congruence of implicit and explicit motives, we assumed that a corresponding explicit affiliation motive leads to satisfaction of the implicit motive. Corresponding affiliation behavior constitutes the second condition. Three studies confirmed the hypothesis that both conditions must be fulfilled in order to positively connect the implicit affiliation motive to emotional well-being. Participants with high implicit and explicit affiliation motives and who additionally showed a large amount of affiliation behavior reported the lowest negative affectivity and the highest life satisfaction compared to participants who lacked one of the conditions.

Critical Afrikaner Intellectuals and Apartheid, 1943–1958

Apartheid dominated the political thinking of two generations of Afrikaner intellectuals from its first conceptualizations in the early 1940s to its disintegration as an ideology during the 1980s. Western Cape politicians, academics, journalists and church leaders were the main contributors to the Sauer Report, which was the greatest influence on the apartheid plank of the National Party's 1948 platform. Although apartheid as a policy did not clinch the NP victory, it won steady support in the course of the 1950s. The article discusses the work of four Afrikaner critics of apartheid as it was conceptualized and implemented in the first decade of NP rule. The most striking observations were those of the ambivalent figure of the poet and essayist N.P. van Wyk Louw, who has remained an important moral voice in the Afrikaner political tradition. André du Toit's Die Sondes van die Vaders (1983) built on some key arguments of Louw in arguing for the abandonment of apartheid as a way of securing Afrikaner survival.     

Symptom perception in childhood asthma: the role of anxiety and asthma severity.

This study tested the relationship of anxiety and asthma severity to symptom perception. Eighty-six children diagnosed with mild or moderate asthma had symptom perception and pulmonary function measured throughout methacholine challenge (to induce bronchoconstriction). Higher trait anxiety was associated with heightened symptom perception (controlling for pulmonary function) at baseline. Greater asthma severity was associated with blunted symptom perception (controlling for pulmonary function) at the end of methacholine challenge and with a slower rate of increase in symptom perception across methacholine challenge. These results suggest that anxiety plays a role when children's symptoms are mild, whereas medical variables such as severity play a role in perception of changes in asthma symptomatology as bronchoconstriction worsens.
