Task control and cognitive abilities of self and spouse in collaboration in middle-aged and older couples

Collaborative problem solving may be used by older couples to optimize cognitive functioning, with some suggestion that older couples exhibit greater collaborative expertise. The study explored age differences in 2 aspects of collaborative expertise: spouses' knowledge of their own and their spouse's cognitive abilities and the ability to fit task control to these cognitive abilities. The participants were 300 middle-aged and older couples who completed a hypothetical errand task. The interactions were coded for control asserted by husbands and wives. Fluid intelligence was assessed, and spouses rated their own and their spouse's cognitive abilities. The results revealed no age differences in couple expertise, either in the ability to predict their own and their spouse's cognitive abilities or in the ability to fit task control to abilities. However, gender differences were found. Women fit task control to their own and their spouse's cognitive abilities; men only fit task control to their spouse's cognitive abilities. For women only, the fit between control and abilities was associated with better performance. The results indicate no age differences in couple expertise but point to gender as a factor in optimal collaboration.     

Accuracy Motivations,Predispositions, and Social Information in Political Discussion Networks

This analysis studies how variation in individuals' motivation to form accurate judgments affects the process of political discussion. I use a small‐group experiment in which participants compete to elect the simulated candidate who best represents their true preferences. I manipulate economic incentives to control participants' accuracy motivations. The results show that accuracy‐motivated participants, compared to those with weaker accuracy goals, seek discussants with more expertise and a more diverse set of viewpoints, place greater emphasis on socially provided messages, and reduce emphasis on political predispositions. As a result of these differences, however, accuracy‐motivated participants rely more heavily on biased information. Hence, accuracy motivations do not produce more accurate judgments or better decisions. Although previous work on political discussion has largely ignored the role of motivations, these results suggest that accuracy motivations play an important but nuanced role in this process. Strengthened accuracy motivations increase individuals' exposure to political expertise and ideological diversity but also increase their potential to be misled.     

The Curse of Expertise: When More Knowledge Leads to Miscalibrated Explanatory Insight

Does expertise within a domain of knowledge predict accurate self‐assessment of the ability to explain topics in that domain? We find that expertise increases confidence in the ability to explain a wide variety of phenomena. However, this confidence is unwarranted; after actually offering full explanations, people are surprised by the limitations in their understanding. For passive expertise (familiar topics), miscalibration is moderated by education; those with more education are accurate in their self‐assessments (Experiment 1). But when those with more education consider topics related to their area of concentrated study (college major), they also display an illusion of understanding (Experiment 2). This “curse of expertise” is explained by a failure to recognize the amount of detailed information that had been forgotten (Experiment 3). While expertise can sometimes lead to accurate self‐knowledge, it can also create illusions of competence.     

Older spouses' perceptions of partners' chronic arthritis pain: implications for spousal responses, support provision, and caregiving experiences

This study of older patients with osteoarthritis and their spouses examined concordance between patients' and spouses' reports of patients' pain severity and the association of concordance with support and caregiving outcomes. Patients and spouses independently viewed videotapes of the patient performing simulated household tasks and provided ratings of patients' pain. Spousal overestimation of patients' pain was the most common type of nonconcordance. Spouses who were accurate in their perceptions of their partner's level of pain during a log-carrying task responded less negatively and provided emotional support that was more satisfying to patients. In addition, spouses who were accurate in their perceptions of their partner's pain during the log-carrying task reported less stress from providing support and assistance. Future research that uses such observational methods may be highly useful for understanding the effects of chronic illness on older couples.     

Attributions and behavior in marital interaction.

To examine whether spouses' attributions for events in their marriage are related to their behavior in interaction, spouses were asked to report their marital quality, to make attributions for marital difficulties, and to engage in problem-solving discussions. Study 1 demonstrated that spouses' maladaptive attributions were related to less effective problem-solving behaviors, particularly among wives. Study 2 showed that spouses' maladaptive attributions were related to higher rates of negative behavior and, for wives, to increased tendencies to reciprocate negative partner behavior. In both studies attributions and behavior tended to be more strongly related for distressed than nondistressed wives. These results support social-psychological models that posit that attributions are related to behavior and models of marriage and close relationships that assume that maladaptive attributions contribute to conflict behavior and relationship dysfunction.     

Medical expertise asa function of task difficulty

This paper is concerned with factors that disrupt the pattern of forward reasoning characteristic of experts with accurate performance. Two experiments are described. In the first, the performances of cardiologists, psychiatrists, and surgeons in diagnostic explanation of a clinical problem in cardiology were examined. In the second, the performances of cardiologists and endocrinologists in diagnostic explanation of clinical problems within and outside their domains of expertise were examined. The performances of researchers and practicing physicians are also compared. The results of Experiment 1 replicated earlier results regarding the relationship between forward reasoning and accurate diagnosis. There were no differences in recall as a function of expertise. Experts did not show any bias toward using specific knowledge from their own areas of expertise. The results of Experiment 2 showed that the breakdown of forward reasoning was related to the structure of the task. In particular, nonsalient cues induced some backward reasoning even in subjects with accurate diagnoses. Some differences were also found between the types of explanation used by researchers and practitioners. The practitioners referred more to clinical components in their explanations, whereas the researchers focused more on the biomedical components.     

Positive expectations in the early years of marriage: should couples expect the best or brace for the worst?

The current study examined whether the effects of positive expectations on changes in marital satisfaction over the first 4 years of marriage were moderated by the nature of spouses' interaction behaviors and relationship attributions. Consistent with predictions, when spouses' skills were most positive, positive expectations predicted more stable satisfaction over time whereas less positive expectations predicted steeper declines. Alternatively, when spouses' skills were most negative, positive expectations predicted steeper declines in satisfaction over time whereas less positive expectations predicted more stable satisfaction. Thus, in contrast to the idea that expectations in the early years of marriage exert main effects on satisfaction, the current findings suggest that the effects of expectations interact with the skills partners bring to their relationships.     

Left or right? Sources of political orientation: the roles of genetic factors, cultural transmission, assortative mating, and personality

In this study, we used an extended twin family design to investigate the influences of genetic and cultural transmission as well as different sources of nonrandom mating on 2 core aspects of political orientation: acceptance of inequality and rejecting system change. In addition, we studied the sources of phenotypic links between Big Five personality traits and political beliefs using self- and other reports. Data of 1,992 individuals (224 monozygotic and 166 dizygotic twin pairs, 92 unmatched twins, 530 spouses of twins, 268 fathers, and 322 mothers) were analyzed. Genetically informative analyses showed that political attitudes are genetically but not environmentally transmitted from parents to offspring and that a substantial proportion of this genetic variance can be accounted for by genetic variance in personality traits. Beyond genetic effects and genotypic assortative mating, generation-specific environmental sources act to increase twins' and spouses' resemblance in political beliefs. The results suggest multiple sources of political orientations in a modern democracy.     

Knowledge and Power in Plato’s Political Thought

Abstract

Plato justifies the concentration and exercise of power for persons endowed with expertise in political governance. This article argues that this justification takes two distinctly different sets of arguments. The first is what I shall call his ‘ideal political philosophy’ described primarily in the Republic as rule by philosopher‐kings wielding absolute authority over their subjects. Their authority stems solely from their comprehension of justice, from which they make political judgements on behalf of their city‐state. I call the second set of arguments Plato’s ‘practical political philosophy’ underlying his later thought, where absolute rule by philosopher‐kings is undermined by the impure character of all political knowledge. Whereas the complete comprehension of justice sanctions the absolute political power of those with this expertise, partial knowledge of justice disallows for such a large investment of power. Plato’s practical political philosophy argues for a mixed theory of governance fusing the institutions of monarchy with democracy in the best practical city‐state. Thus, Plato comes to realize the insurmountable difficulties of his ideal political thought, preferring a more practical political philosophy instead.     

Husbands' and Wives' Attachment Orientations and Depressive Symptoms: Predictors of Positive and Negative Conflict Behaviors in the Marriage

The present study examined both husbands' and wives' attachment orientations and depressive symptoms in predicting reports of marital conflict behaviors. Married couples (N = 60) completed questionnaires to assess their attachment orientations, depressive symptoms, and perceptions of positive and negative conflict behaviors in the marital relationship. Using hierarchical regression analyses, statistical models were tested wherein husbands' and wives' reports of marital conflict behaviors were regressed on their own and their spouses' attachment orientations and depressive symptoms. The results suggest that both attachment orientations and depressive symptoms were important predictors of reported marital conflict behaviors. However, different predictors were found for husbands' and wives' reports of positive and negative conflict behaviors. In general, spouses' attributes played only a small role in predicting reports of marital conflict behaviors.     

Evaluation of a cognitive behavioral group intervention program for spouses of stroke patients

This study investigated the effectiveness of a cognitive behavioral group program for spouses of stroke patients. The program consists of 15 bi-monthly 112h sessions. The goal of the intervention is to reduce the prevalence of mental disorders and burnout among care-giving spouses of stroke patients. The sample (stroke patients and their spouses) consisted of one intervention group (n=38 couples) and two different control conditions, those receiving informational support (n=35 couples) and those receiving standard care (n=51 couples). We used the following instruments to measure spouses' mental health and quality of life: Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), WHO Quality of Life Questionnaire. Measurements were taken before the intervention (Time 1), directly following the intervention (Time 2) and 6 months after Time 2 (Time 3). Several regression analyses allowed for examination of the short-term and long-term effects of the intervention. The spouses' participation in the intervention program was associated with significant short-term changes in care-giving spouses' quality of life and with long-term changes in their quality of life and depression. The presented multi-component intervention appears to have an immediate effect on care-giving spouses' quality of life. In contrast, the intervention-related changes in more resistant mental-health-related variables did not appear until after a latent stage in the later post-intervention phase.     

Effects of received and mobilized support on recipients' and providers' self-efficacy beliefs: a 1-year follow-up study with patients receiving radical prostatectomy and their spouses

From a proactive agentic perspective, social support is not just seen as a protective cushion against environmental demands. Rather, support may facilitate an individual's self-regulation by enhancing perceived self-efficacy (i.e., enabling hypothesis). In the present study, patient-reported indicators of mobilized and received spousal support as predictors of their own and their spouses' self-efficacy beliefs were investigated within 1 year following radical prostatectomy. During this time frame, postoperative sequelae such as urinary incontinence and erectile dysfunctions are still likely to interfere with couples' everyday activities. Seventy-two patients receiving radical prostatectomy and their spouses participated. Patients' and spouses' self-efficacy beliefs and patients' received and mobilized spousal support were assessed prior to and 12 months following surgery. Additional patient-reported covariates at 1 year post-surgery were degree of bother by urinary incontinence, overall sexual satisfaction, and relationship satisfaction. Results indicated that patients' received spousal support was associated with higher levels of patients' self-efficacy only cross-sectionally, but not longitudinally. Support mobilized by the patient prior to and 1 year after surgery, however, positively predicted spouses' levels and changes in self-efficacy. Results, thus, did not fully confirm predictions by the enabling hypothesis of social support; rather, associated aspects, such as the degree of being mobilized as a provider of support or being needed, seem to enhance agency beliefs in spouses.     

Trust, Confidence, and Expertise in a Judge-Advisor System

The relationship between trust, confidence, and expertise in Judge-Advisor Systems is examined in two experiments with Judge-Advisor pairs, one with strangers and another with participants in ongoing relationships. There was expertise asymmetry so that Judges had less expertise than their Advisors. The dyads could receive money for accurate Judge decisions. Either the Judge or Advisor had the power to allocate this money between dyad members, before task interaction in study one and after task completion in study two. Because Judges were more dependent on Advisors than vice versa, it was predicted that trust would be more important to Judges. Results were supportive. Judges had higher and more variable ratings of trust in their partner than did Advisors, suggesting that Judges were more motivated to evaluate trust. High confidence by Advisors had a positive impact on Judges' ratings of trust and tendency to follow their advice. Judges' trust in their Advisors was significantly related their taking the advice and being confident in their final decisions. Although participants in study two had higher levels of trust in their partners, they allocated less money to them. The implications for establishing trust are discussed.     

Individual Characteristics of Political Leaders and the Use of Analogy in Foreign Policy Decision Making

The linkages between individual characteristics of political leaders and their usage of historical analogy during foreign policy decision-making episodes were examined. The individual characteristics studied were conceptual complexity and policy expertise, while usage of analogy was studied in terms of the sophistication and source of historical comparisons. The great majority of the analogies used by low-complexity individuals were nonsophisticated, whereas high-complexity individuals consistently used more sophisticated analogies. Low-complexity individuals drew analogies solely from their own generational and cultural context, while high-complexity leaders drew their analogies from a wider range of sources. More expert leaders drew from their personal experiences to a marginally greater degree than less expert individuals but, interestingly, both types of individual relied on generally available rather than personally experienced events for their analogies. The value added of the approach is to demonstrate that different types of leaders use history differently during political decision making.     

Expertise as Argument: Authority,Democracy, and Problem-Solving

This article addresses the problem of expertise in a democratic political system: the tension between the authority of expertise and the democratic values that guide political life. We argue that for certain problems, expertise needs to be understood as a dialogical process, and we conceptualize an understanding of expertise through and as argument that positions expertise as constituted by and a function of democratic values and practices, rather than in the possession of, acquisition of, or relationship to epistemic materials. Conceptualizing expertise through argument leads us to see expertise as a kind of phronetic practice, oriented toward judgments and problems, characterized by its ability to provide inventional capacities for selecting the best possible resolution of a particular problem vis-à-vis particular expectations regarding the resolution of a problem. At its core, expertise thus comes to exist in reference not to epistemic but to dialogical, deliberative, democratic practice.     

Law,professional practice,and professional organizations: Where do we go from here?

The ethical dilemmas presented to the practicing school psychologist by the plethora of laws that dictate procedures, policies, and instrumentation are discussed. The function of professional organizations, both national and state, is described as (a) anticipating legislation, (b) developing political impact, (c) affecting existing laws, and (d) affecting proposed legislation. Coordination of efforts among various groups and development of political expertise is urged as a way to approach issues of concern to both psychologists and their clients.     

Experts on age estimation

The aim of this investigation was to study the biases and accuracy in age estimation of persons selling alcohol. Two experiments are reported, both suggesting that the accuracy in age estimation of Swedish alcohol salespersons is higher than that of control persons. This expertise in age estimation is probably the result of the extensive training Swedish alcohol salespersons go through as a natural part of their profession. Nonetheless, their estimates were not free from bias. Salespersons overestimated the age of target persons below 20 years of age and thus too young to buy alcohol. The results also revealed that controls, in contrast to salespersons, assimilated their estimates towards their own age (i.e. an own-anchor effect). Furthermore, female participants were shown to estimate the age of old target persons (56–65 years) more accurately than male participants. These results are discussed in relation to previous findings on training in age estimation and present jurisdiction.     

Forgiveness in marriage: putting the benefits into context.

The current longitudinal study examined the consequences of spouses' tendencies to forgive their partners over the first 2 years of 72 new marriages. Though positive main effects between forgiveness and marital outcomes emerged cross-sectionally, spouses' tendencies to forgive their partners interacted with the frequency of those partners' negative verbal behaviors to predict changes in marital outcomes longitudinally. Specifically, whereas spouses married to partners who rarely behaved negatively tended to remain more satisfied over time to the extent that they were more forgiving, spouses married to partners who frequently behaved negatively tended to experience steeper declines in satisfaction to the extent that they were more forgiving. Similar patterns emerged for changes in the severity of husbands' problems, such that husbands married to wives who frequently behaved negatively reported sharper increases in problem severity to the extent that they were more forgiving but reported more stable problem severity to the extent that they were less forgiving. These findings question whether all spouses should benefit from forgiveness interventions and thus highlight the need for further research on the most appropriate targets for such interventions.     

Perceptual expertise enhances the resolution but not the number of representations in working memory

Despite its central role in cognition, capacity in visual working memory is restricted to about three or four items. Curby and Gauthier (2007) examined whether perceptual expertise can help to overcome this limit by enabling more efficient coding of visual information. In line with this, they observed higher capacity estimates for upright than for inverted faces, suggesting that perceptual expertise enhances visual working memory. In the present work, we examined whether the improved capacity estimates for upright faces indicates an increased number of "slots" in working memory, or improved resolution within the existing slots. Our results suggest that perceptual expertise enhances the resolution but not the number of representations that can be held in working memory. These results clarify the effects of perceptual expertise in working memory and support recent suggestions that number and resolution represent distinct facets of working memory ability.     

How does context affect intimate relationships? linking external stress and cognitive processes within marriage

Stressors external to the marriage frequently affect the way spouses evaluate their marital quality. To date, however, understanding of the interplay between external stress and internal relationship processes has been limited in two ways. First, research has generally examined only the short-term consequences of stress. Second, the mechanisms through which external stressors influence relationship outcomes are unclear. This study addressed both limitations by examining relationship cognitions that may mediate the effects of external stress throughout 4 years of marriage. Analyses confirmed that stressful experiences were associated with the trajectory of marital quality overtime. Furthermore, both the content and the organization of spouses' specific relationship cognitions mediated this effect. That is, stress negatively influenced the nature of spouses' marital perceptions as well as the way spouses interpreted and processed those perceptions. These findings draw attention to ways that the context of relationships shapes and constrains relationship processes.
