Thickness and the Koffka ring effect

Over seven decades ago Gestalt psychologist Kurt Koffka described a remarkable effect: when a contiguous gray ring is placed on a background half of one shade of gray, half of another, the ring appears homogeneous. However, if the ring is slightly divided, the two halves of the ring appear different shades of gray, the half of the ring on the darker background appearing lighter than the half of the ring on the lighter background. The Gestalt principle of continuity is used to explain this effect. We show that when the ring is made thinner it appears heterogeneous even when contiguous. We also illustrate this in the additional material with a colored background with more than two regions.     

Protecting confidentiality rights: the need for an ethical practice model

All psychologists must uphold the same ethical standards about confidentiality even though each state imposes different legal limits on their ability to protect clients' confidences. The resulting ethical-legal confusion is exacerbated by legally based confidentiality training that treats legal exceptions as if they were the rule and fosters the impression that attorneys are now the only real experts about this aspect of practice. This article provides an ethics-based confidentiality practice model that clarifies the ethical rule and puts its legal exceptions into ethical perspective. Like the Confidentiality section of the American Psychological Association's (2002) Ethical Principles of Psychologists and Code of Conduct, this outline would apply to all psychologists regardless of state laws, but the details of its implementation would vary according to role and setting. It can be used as a universal training outline, a consultation and supervision tool, a guide to professional practice, and a basis for clearer ongoing conversation about the ethics of "conditional confidentiality." Psychologists can use this practice model to regain their status as experts about the confidentiality ethics of their own profession.     

Contextual control of slot-machine gambling: replication and extension

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines.     

Evaluating a brief prevention program for improving marital conflict in community families.

Marital conflict is related to well-being in children and adults (E. M. Cummings & P. T. Davies, 2002). Marital conflict is likely most effectively ameliorated before it becomes clinically significant. However, families without significant problems may be unwilling to participate in couples therapies or other lengthy or intensive interventions. Responding to this gap, the authors developed a 4-session psychoeducational program about marital conflict for community families. Couples with children 4-8 years of age were randomly blocked into 1 of 3 groups: (1) a parent-only group (n = 24), (2) a parent-child group (n = 33), or (3) a self-study group (n = 33). Pre- and posttest and 6-month and 1-year assessments were conducted. This report evaluates (a) whether participation in a psychoeducational program for parents improved marital conflict, especially concerning ways of expressing disagreements, and (b) whether changes in marital conflict subsequently improved marital satisfaction, parenting, and child adjustment. Greater constructive and less destructive marital conflict was observed at all assessments for treatment groups, and these changes were linked with improvements in other family processes. The findings support the promise of brief, psychoeducational programs for improving marital conflict for community samples.     

Parental expressed emotion toward children: prediction from early family functioning

Expressed emotion (EE), an index of family member criticism and emotional overinvolvement, predicts outcome among adults and children with mental disorders. However, limited research exists on factors contributing to EE. Aims of the current study were to (a) examine EE in mothers of young children; (b) assess relationships between demographic factors and EE in a diverse sample; and (c) investigate whether family stress and functioning, including quality of marital relationship, life events, maternal stress, and family environment, predict EE. In the current study, 276 mothers completed questionnaires when their children were between 1 and 3 years of age and a measure of EE when their children were in kindergarten. Results indicated that family expressiveness was the most consistent predictor of EE. Further research seems warranted to better delineate associations between family functioning and EE.     

Pathways to childhood depressive symptoms: the role of social, cognitive, and genetic risk factors

Childhood depressive conditions have been explored from multiple theoretical approaches but with few empirical attempts to address the interrelationships among these different domains and their combined effects. In the present study, the authors examined different pathways through which social, cognitive, and genetic risk factors may be expressed to influence depressive symptoms in 300 pairs of child twins from a longitudinal study. Path analysis supported several indirect routes. First, risks associated with living in a step- or single-parent family and punitive parenting did not directly influence depressive outcome but were instead mediated through maternal depressive symptoms and child negative attributional style. Second, the effects of negative attributional style on depressive outcome were greatly exacerbated in the presence of precipitating negative life events. Third, independent of these social and cognitive risk mechanisms, modest genetic effects were also implicated in symptoms, with some indication that these risks are expressed through exposure to negative stressors. Together, these routes accounted for approximately 13% of total phenotypic variance in depressive symptoms. Theoretical and analytical implications of these results are discussed in the context of several design-related caveats.     

Metaperceptions of bias in intimate relationships

Meta-awareness of bias in intimate partner judgments was investigated in 3 studies. In Study 1, participants rated fictional partners in happier relationships as more positively biased in their partner perceptions. In Study 2, participants thought their judgments of their own current partners were positively biased and that they were judged by their partners in a positively biased fashion. Using a sample of couples, Study 3 showed that metaperceptions of bias were anchored to actual levels of bias at the individual and relationship levels. In addition, positive bias was accentuated for traits that were more relevant to mate evaluation. These findings (as expected) suggest that positive bias in partner judgments can be a normative and consciously accessible feature of intimate relationships.     

How to handle anxiety: The effects of reappraisal, acceptance, and suppression strategies on anxious arousal

It has been suggested that reappraisal strategies are more effective than suppression strategies for regulating emotions. Recently, proponents of the acceptance-based behavior therapy movement have further emphasized the importance of acceptance-based emotion regulation techniques. In order to directly compare these different emotion regulation strategies, 202 volunteers were asked to give an impromptu speech in front of a video camera. Participants were randomly assigned to one of three groups. The Reappraisal group was instructed to regulate their anxious arousal by reappraising the situation; the Suppression group was asked to suppress their anxious behaviors; and the Acceptance group was instructed to accept their anxiety. As expected, the Suppression group showed a greater increase in heart rate from baseline than the Reappraisal and Acceptance groups. Moreover, the Suppression group reported more anxiety than the Reappraisal group. However, the Acceptance and Suppression groups did not differ in their subjective anxiety response. These results suggest that both reappraising and accepting anxiety is more effective for moderating the physiological arousal than suppressing anxiety. However, reappraising is more effective for moderating the subjective feeling of anxiety than attempts to suppress or accept it.
