Level validity of self-report whole-family measures

This article introduces an approach to testing the level validity of family assessment instruments (i.e., whether a family instrument measures family functioning at the level of the system it purports to assess). Two parents and 2 adolescents in 69 families rated the warmth in each of their family relationships and in the family as a whole. Family members' ratings of whole-family warmth assessed family functioning not only at the family level (i.e., characteristics of the family as a whole) but also at the individual level of analysis (i.e., characteristics of family members as raters), indicating a lack of level validity. Evidence was provided for the level validity of a latent variable based on family members' ratings of whole-family warmth. The findings underscore the importance of assessing the level validity of individual ratings of whole-family functioning.     

Concavities count for less in symmetry perception

We investigated the relative importance of convexities (protrusions) and concavities (indentations) for the perception of shape. On the one hand, it has been suggested that convexities determine the shape of an object, whereas concavities merely act as “perceptual glue” between the convexities. On the other hand, it has been argued that concavities are more salient than convexities. We show that participants find it easier to detect asymmetry in a 2-D silhouette when there is a mismatch between the shapes of convexities on either side of the axis of symmetry than when there is a mismatch between the shapes of concavities. This is the case even when the concavities are closest to the axis of symmetry, and despite the usual bias toward this axis in symmetry perception. We suggest that the actual shape of concavities is less important in symmetry perception, because the main role of concavities is to act as part boundaries in the representation of the shape of objects.     

Ethical Problems Inherent in Psychological Research based on Internet Communication as Stored Information

This paper deals with certain ethical problems inherent in psychological research based on internet communication as stored information. Section 1 contains an analysis of research on Internet debates. In particular, it takes into account a famous example of deception for psychology research purposes. In section 2, the focus is on research on personal data in texts published on the Internet. Section 3 includes an attempt to formulate some ethical principles and guidelines, which should be regarded as fundamental in research on stored information.     

Brain activation while forming memories of fearful and neutral faces in women and men

Event-related functional MRI (fMRI) was used to assess brain activity during encoding of fearful and neutral faces in 12 women and 12 men. In a subsequent memory analysis, the authors separated successful from unsuccessful encoding of both types of faces, based on whether they were remembered or forgotten in a later recognition memory test. Overall, women and men recruited overlapping neural circuitries. Both sexes activated right-sided medial-temporal regions during successful encoding of fearful faces. Successful encoding of neutral faces was associated with left-sided lateral prefrontal and right-sided superior frontal activation in both sexes. In women, relatively greater encoding related activity for neutral faces was seen in the superior parietal and parahippocampal cortices. By contrast, men activated the left and right superior/middle frontal cortex more than women during successful encoding of the same neutral faces. These findings suggest that women and men use similar neural networks to encode facial information, with only subtle sex differences observed for neutral faces.     

Measuring fear of movement/(re)injury in chronic low back pain using implicit measures

Fear of movement/(re)injury is assumed to contribute to the development and maintenance of chronic low back pain (CLBP) in a subgroup of patients. Studying fear of movement/(re)injury with implicit attitude measures, without the awareness of the patient, might be a valuable addition to self-report questionnaires. The aims of the current study were to investigate whether CLBP patients demonstrate more implicit fear of movement/(re)injury than healthy controls, and whether 2 implicit measures are related to each other, and to an explicit self-report measure of fear of movement/(re)injury. A group of 66 CLBP patients and 30 healthy controls took part in this study. In addition to self-report questionnaires, fear of movement/(re)injury was implicitly assessed by the Extrinsic Affective Simon Task (EAST) and the Go-No-Go-Association Task (GNAT) that aimed to determine the association between back-stressing movements and the evaluation "threatening". On both implicit tasks it was found that neither CLBP patients nor healthy controls demonstrated implicit fear of movement/(re)injury, and that CLBP patients did not differ from healthy controls in their level of implicit fear of movement/(re)injury. In general, no associations were found between the EAST and the GNAT, or between implicitly measured and self-reported fear of movement/(re)injury. One major caveat in drawing inferences from these findings is the poor reliability of these implicit measures. Research towards the psychometric properties of these measures should first be expanded before modifying, and applying, them to more complex domains such as fear of movement/(re)injury.     

Self-analysis and post-termination improvement after psychoanalysis and long-term psychotherapy

Long-term follow-up studies of long-term psychoanalytically oriented psychotherapy or psychoanalysis are extremely rare, and few have focused on the post-treatment process itself. In the Stockholm Outcome of Psychoanalysis and Psychotherapy project, one of the results was that patients in psychoanalysis continued to improve after termination to a higher degree than patients in long-term psychotherapy. In this study 20 patients selected from the project were interviewed on two occasions, one and two years after termination, in order to explore how they described their post-treatment processes. The interviews were studied qualitatively using a multiple case study design, and categories of different types of post-treatment development were created from these case studies. Results indicate that the variation within treatment groups is large, and that development may continue in several ways after termination. The most striking difference between psychoanalysis and psychotherapy was not, as hypothesized, in the self-analytic function, but in various self-supporting strategies described by former analysands but not by former psychotherapy patients. However, only self-analysis was significantly correlated with post-termination improvement across both treatments. Three patients improving after termination and three deteriorating are described in detail as illustrations. Some methodological constraints of the design limit the generalizeability of results.     

Type D personality as a prognostic factor in heart disease: assessment and mediating mechanisms

Type D personality, a synergy between negative affectivity and social inhibition, has established itself as a serious risk factor for morbidity and mortality in patients suffering from cardiovascular disease. In this review, we summarize studies on the validity of the assessment methods of Type D, emphasizing its role as an independent vulnerability factor in the progression of cardiovascular disease. We further present evidence on the physiological characteristics that accompany the 2 psychological traits negative affectivity and social inhibition and may mediate the relation between personality and prognosis in heart disease. Further research needs to determine the mechanisms by which Type D affects the course and outcome of cardiovascular disease as well as how Type D patients may benefit from psychosocial intervention.     

Modeling Reasoning in a Social Setting

In this survey and position paper, we discuss some issues in logical modeling of interactive behavior. We draw together a number of lines in current logics for social action, emphasizing uses of ‘small models’ rather than complex spaces.     

The Leuven Perceptual Organization Screening Test (L-POST), an online test to assess mid-level visual perception

Neuropsychological diagnostic tests of visual perception mostly assess high-level processes like object recognition. Object recognition, however, relies on distinct mid-level processes of perceptual organization that are only implicitly tested in classical tests. The Leuven Perceptual Organization Screening Test (L-POST) fills a gap with respect to clinically oriented tests of mid-level visual function. In 15 online subtests, a range of mid-level processes are covered, such as figure–ground segmentation, local and global processing, and shape perception. We also test the sensitivity to a wide variety of perceptual grouping cues, like common fate, collinearity, proximity, and closure. To reduce cognitive load, a matching-to-sample task is used for all subtests. Our online test can be administered in 20–45 min and is freely available at www.gestaltrevision.be/tests. The online implementation enables us to offer a separate interface for researchers and clinicians to have immediate access to the raw and summary results for each patient and to keep a record of their patient’s entire data. Also, each patient’s results can be flexibly compared with a range of age-matched norm samples. In conclusion, the L-POST is a valuable screening test for perceptual organization. The test allows clinicians to screen for deficits in visual perception and enables researchers to get a broader overview of mid-level visual processes that are preserved or disrupted in a given patient.     

Personality Predicts Obedience in a Milgram Paradigm

This study investigates how obedience in a Milgram‐like experiment is predicted by interindividual differences. Participants were 35 males and 31 females aged 26–54 from the general population who were contacted by phone 8 months after their participation in a study transposing Milgram's obedience paradigm to the context of a fake television game show. Interviews were presented as opinion polls with no stated ties to the earlier experiment. Personality was assessed by the Big Five Mini‐Markers questionnaire (Saucier, 1994). Political orientation and social activism were also measured. Results confirmed hypotheses that Conscientiousness and Agreeableness would be associated with willingness to administer higher‐intensity electric shocks to a victim. Political orientation and social activism were also related to obedience. Our results provide empirical evidence suggesting that individual differences in personality and political variables matter in the explanation of obedience to authority.
