A categorical and dimensional perspective on depression within a nonclinical sample of couples

The present study investigated the role of psychosocial variables that are indicators for depressive symptomatology within a couple. The variables chosen for this study were conflict communication, marital adjustment, attachment, attribution style, and personality traits--all potentially specific indicators. A global factor analysis on all our measures revealed that our individual and relational measures were stable findings. We wanted to compare a dimensional and categorical view of depression. First, we focused on the total nonclinical sample, considering depression on a continuum, and studying the selected characteristics along with the varying degree of depressive complaints. The results highlighted the importance of individual characteristics (neuroticism and life satisfaction) covarying with the level of depressive symptomatology in the nonclinical sample (n = 186 couples). Second, in addition to this correlational design, we compared the group of most depressed subjects and their partners with a control sample (n = 34). Both approaches pointed to the same conclusion: individual characteristics covaried with mild depression, whereas couple characteristics only came into the picture with a higher level of depressive complaints. The lowest levels of depressive complaints were associated with individual co-morbidity only, whereas increasing complaints went along with additional relational complaints. Implications for assessment and future research are discussed.     

Verifying simple arithmetic sums and products: Are the phonological loop and the central executive involved?

In two experiments, we investigated the role of the phonological loop and the central executive in the verification of the complete set of one-digit addition (Experiment 1) and multiplication (Experiment 2) problems. The focus of the present study was on the contradictory results concerning the contribution of the phonological loop in the verification of true problems (e.g., 8 + 4 = 12 or 4 x 6 = 24) reported until now. The results revealed that this slave system is not involved in verifying simple arithmetic problems, in contrast to the central executive. Furthermore, our results indicated that the split effect is due to the use of two different arithmetic strategies.     

Conceptualizations of Fair Play: A Factorial Survey Study of Moral Judgments by Badminton Players

There is much discussion in sports on whether certain behavior should be considered Fair Play. This moral judgment on Fair Play is influenced by the conceptualization of the term Fair Play as either “respect for the rules” or “respect for the spirit of the game,” as well as by other determinants. To uncover the moral judgment of athletes and which conceptualization of Fair Play dominates in practice, a factorial survey approach is used. The act and the level of the match played a role in the judgment, as well as the gender of the athlete. Our results showed that both conceptualizations “respect for the rules” and “respect for the spirit of the game” were important in this judgment, with the spirit conceptualization being more dominant.     

The implicit association test as a general measure of similarity.

The Implicit Association Test (IAT) is widely used as a measure of semantic similarity (i.e., associations in semantic memory). The results of previous research and of a new study show that IAT effects can, however, also be based on other types of similarity between stimuli. We therefore put forward the hypothesis that the IAT provides a general measure of similarity. Given that similarity is highly dynamic and context-dependent, our view that the IAT measures similarity is compatible with existing evidence showing that IAT effects are highly malleable. We provide further evidence for this in a new study in which the outcome of an IAT depended on whether the perceptual or functional characteristics of the stimuli were made salient.     

An interpersonal perspective on depression: the role of marital adjustment, conflict communication, attributions, and attachment within a clinical sample

Previous studies have focused on the difficulties in psychosocial functioning in depressed persons, underscoring the distress experienced by both spouses. We selected conflict communication, attribution, and attachment as important domains of depression in the context of marital adjustment, and we analyzed two hypotheses in one single study. First, we analyzed whether a clinical sample of couples with a depressed patient would differ significantly from a control group on these variables. Second, we explored to what degree these variables mediate/moderate the relationship between depressive symptoms and marital adjustment. The perspectives of both spouses were taken into account, as well as gender differences. In total, 69 clinical and 69 control couples were recruited, and a series of multivariate analyses of variance and regression analyses were conducted to test both hypotheses. Results indicated that both patients and their partners reported less marital adjustment associated with more negative perceptions on conflict communication, causal attributions, and insecure attachment. In addition, conflict communication and causal attributions were significant mediators of the association between depressive symptoms and marital adjustment for both depressed men and women, and causal attributions also moderated this link. Ambivalent attachment was a significant mediator only for the female identified patients. Several sex differences and clinical implications are discussed.     

Implicit attitudes towards meat and vegetables in vegetarians and nonvegetarians

Previous research, in which self‐report measures were used, showed that vegetarians have more negative beliefs about meat than nonvegetarians. An important limitation of this research is that it did not examine differences in spontaneous affective reactions (i.e., implicit attitudes) towards meat and other types of food. We therefore conducted a new study in which not only self‐report measures were used, but also two tasks that have been developed to measure implicit attitudes: The Implicit Association Test (IAT) and a pictorial version of the Extrinsic Affective Simon Task (EAST). Both the IAT and EAST revealed that implicit attitudes towards vegetables (as compared to implicit attitudes towards meat) were more positive in vegetarians than in nonvegetarians. In line with previous findings, the self‐report measures showed that, compared to nonvegetarians, vegetarians had more positive attitudes towards vegetables and more negative attitudes towards meat. The IAT and EAST measures both correlated in the expected manner with self‐reported attitudes. A logistic regression showed that self‐reported attitudes were an almost perfect predictor of group status (vegetarian or nonvegetarian), and that adding the IAT and EAST measures as predictors did not improve prediction of group status. The results suggest that vegetarians and nonvegetarians differ in their spontaneous affective reaction towards vegetables or meat, and provide further evidence for the validity of the IAT and EAST as measures of inter‐individual differences in attitudes. Implicit attitudes could influence eating behaviour indirectly by biasing the decision to become a vegetarian or by determining how difficult it is for someone to maintain a vegetarian diet.     

The contribution of working memory resources in the verification of simple mental arithmetic sums

The present study replicated the investigations of Lemaire, Abdi, and Fayol with some modifications: the random time interval generation (RIG) task was used and the stimuli were created in another way. The results provide additional evidence for the crucial role of the central executive in the speed of solving both true and false sums and for the role of the phonological loop in solving false sums. However, the findings concerning the role of this slave system in solving true sums were different. Possible explanations and limitations of these results are discussed.
