Perceived sacrifice and few alternatives commitments: The motivational underpinnings of continuance commitment's subdimensions

Using work on self-concepts and Conservation of Resources theory, the present research examined the motivational underpinnings of continuance commitment's subcomponents of perceived sacrifice and few alternatives. Study 1 (N = 208) found job scope to be positively related to perceived sacrifice commitment, and negatively related to few alternatives commitment. Study 2 (N = 147) found empowerment's meaning dimension to be positively related to perceived sacrifice commitment and self-determination to be negatively linked to few alternatives commitment. In Study 3 (N = 301), perceived sacrifice commitment was found to be positively related to feedback seeking, while few alternatives commitment was negatively related to it. Finally, Study 4 (N = 278) found perceived sacrifice commitment to be positively, and few alternatives commitment negatively, related to career success (promotion and pay raise decisions). Implications of these findings are discussed.     

The shared leadership process in decision-making teams

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership.     

Die verbale Aktivit?t in therapeutischen Dialogen

The discourse in psychotherapeutic treatment is less specific than usually expected so the question arises whether different therapy methods are different in the style of communication. In this study the verbal activity and other characteristics of the discourse of therapist and patient for sessions from two psychoanalytic, two psychodynamic and two cognitive behavior therapies were compared. Psychoanalytic therapists were found to talk the least and behavior therapists the most. Patients talk nearly the same amount in all therapies. As therapists of psychoanalytic treatment talk less than behavior therapists the percentage of patient talking is highest in psychoanalytic therapy. Further formal characteristics: statements are the most frequent form of intervention in behavior therapy (51?%), followed by psychodynamic (36?%) and psychoanalytic therapy (27?%). The most frequent form of intervention in psychodynamic and psychoanalytic therapy is listening, whereas it is only a small part of communication in behavior therapy. Questions are asked most often in behavior therapy. Hence there are significant differences which correspond to the theory of treatment, between the three methods in discourse behavior on a single case level.     

Manipulations of attention enhance self-regulation

Successful goal-directed behavior requires self-regulation to override competing impulses. Emerging evidence suggests that attention may mediate such acts, but little is known about the specific operations through which attention might influence self-regulation. Here we test this often-implicit assumption by manipulating attention mechanisms in two ways: one controlling the inhibition of inappropriate responses; the other controlling the breadth of attention. Participants significantly improved their performance on a self-regulation task after practice on a response inhibition task (Experiment 1) and after the induction of a broad focus of attention in a visual discrimination task (Experiment 2). We propose that such manipulations enhance self-regulation by engaging mechanisms that enhance the salience of goal-related representations and reduce the activation of competing goal-irrelevant neural representations. By more efficiently resolving conflict among the signals vying to drive behavior, pre-engaging attention may also help to conserve resources needed for continued self-regulation.     

Implicit response-irrelevant number information triggers the SNARC effect: Evidence using a neural overlap paradigm

There is evidence from the SNARC (spatial-numerical association of response codes) effect and NDE (numerical distance effect) that number activates spatial representations. Most of this evidence comes from tasks with explicit reference to number, whether through presentation of Arabic digits (SNARC) or through magnitude decisions to nonsymbolic representations (NDE). Here, we report four studies that use the neural overlap paradigm developed by Fias, Lauwereyns, and Lammertyn (2001) to examine whether the presentation of implicit and task-irrelevant numerosity information (nonsymbolic arrays and auditory numbers) is enough to activate a spatial representation of number. Participants were presented with either numerosity arrays (1-9 circles or triangles) to which they made colour (Experiment 1) or orientation (Experiment 2) judgements, or auditory numbers coupled with an on-screen stimulus to which they made a colour (Experiment 3) or orientation (Experiment 4) judgement. SNARC effects were observed only for the orientation tasks. Following the logic of Fias et al., we argue that this SNARC effect occurs as a result of overlap in parietal processing for number and orientation judgements irrespective of modality. Furthermore, we found stronger SNARC effects in the small number range (1-4) than in the larger number range (6-9) for both nonsymbolic displays and auditory numbers. These results suggest that quantity is extracted (and interferes with responses in the orientation task) but this is not exact for the entire number range. We discuss a number of alternative models and mechanisms of numerical processing that may account for such effects.     

Self- and social perception of physical appearance in chest wall deformity

This study analyzes self- and social perception of physical appearance in patients with chest wall deformity (CWD), including both pectus carinatum and pectus excavatum. Self-perception of appearance in 76 patients with CWD and social perception of patients' appearance by 20 adult and 20 adolescent raters was assessed using the Appearance Rating Scale (Stangier et al., 2000) and evaluated for agreement and multivariate correlates. Results indicate no agreement between self- and social rating. Based on mean scores patients rated their appearance significantly more negatively than adult raters but only slightly different than adolescent raters. Adolescent raters' judgment of the patients' appearance was related to CWD characteristics, while self-rating rather seems to be related to psychosocial factors. Because adolescents are a relevant peer group for adolescent patients with CWD their evaluation of the appearance might influence patients' self-image and might affect their psychological functioning. Effective interventions focusing on social interactions are needed.     

Changing eating behaviour vs. losing weight: the role of goal focus for weight loss in overweight women

A 6-week longitudinal study with N?=?126 overweight women participating in a weight-loss programme investigated the hypothesis that focusing on the process (dietary behaviours) rather than on the outcome of dieting (weight loss) is associated with more successful goal pursuit and achievement. As expected, process focus was related positively to subjective daily success in dieting as well as to actual weight loss, and negatively to deviations from the diet. In contrast, outcome focus had a negative impact on successful dieting: focusing on weight loss was marginally negatively related to actual weight loss and was associated with more disinhibition after lapses. Confirming hypotheses, self-regulation failure (i.e. deviations from the diet, disinhibition) was negatively related to daily affective well-being. Contrary to hypotheses, however, goal focus was not directly associated with affective well-being but only indirectly through self-regulation. Focusing on the process rather than on the outcome of dieting, then, might help achieving difficult health-related goals and support self-regulation but does not contribute directly to affective well-being.     

Perceived partner support in pregnancy predicts lower maternal and infant distress

Maternal postpartum emotional distress is quite common and can pose significant risk to mothers and infants. The current study investigated mothers' relationships with their partners during pregnancy and tested the hypotheses that perception of prenatal partner support is a significant predictor of changes in maternal emotional distress from midpregnancy to postpartum, and contributes to maternal ratings of infant distress to novelty. Using a prospective longitudinal design, 272 adult pregnant women were interviewed regarding their partner support, relationship satisfaction, and interpersonal security (attachment style and willingness to seek out support), and they completed standardized measures of prenatal symptoms of depression and anxiety (distress). At 6 to 8 weeks' postpartum, mothers reported these symptoms again and completed measures of their infants' temperament. Structural equation modeling (SEM) was used to test direct and indirect contributions of partner support, relationship satisfaction, and interpersonal security to maternal and infant postpartum distress. Mothers who perceived stronger social support from their partners midpregnancy had lower emotional distress postpartum after controlling for their distress in early pregnancy, and their infants were reported to be less distressed in response to novelty. Partner support mediated the effects of mothers' interpersonal security and relationship satisfaction on maternal and infant outcomes. A high-quality, supportive partner relationship during pregnancy may contribute to improved maternal and infant well-being postpartum, indicating a potential role for partner relationships in mental health interventions, with possible benefits for infants as well.
