A Logical Analysis of Monty Hall and Sleeping Beauty

Hintikka and Sandu’s independence-friendly (IF) logic is a conservative extension of first-order logic that allows one to consider semantic games with imperfect information. In the present article, we first show how several variants of the Monty Hall problem can be modeled as semantic games for IF sentences. In the process, we extend IF logic to include semantic games with chance moves and dub this extension stochastic IF logic. Finally, we use stochastic IF logic to analyze the Sleeping Beauty problem, leading to the conclusion that the thirders are correct while identifying the main error in the halfers’ argument.     

Neurocognitive predictors of performance‐based functional capacity in bipolar disorder

Neurocognitive impairment can predict functional capacity in individuals with bipolar disorder, though little research has examined whether different neurocognitive domains impact specific types of tasks. This study examined the relationship between several neurocognitive variables and the UCSD Performance‐Based Skills Assessment (UPSA; Patterson et al., 2011) to identify the domains and tests that best predict the performance across the subscales. Forty‐seven euthymic participants who were diagnosed with either Bipolar I or Bipolar II were recruited and assessed on a battery of neuropsychological measures and the UPSA. Correlational and regression analyses were run to identify neurocognitive predictors of UPSA subscales. Per the literature, verbal learning and memory and executive function composites were first examined. Verbal learning and memory predicted the Communication subscale and Total score variables above and beyond the estimated FSIQ and symptom rating scales. In a secondary exploratory analysis, the Benton Judgment of Line Orientation subtest predicted the Finance subscale while the California Verbal Learning Test predicted the UPSA total score. Verbal learning and memory emerged as the strongest predictor of functional capacity, suggesting that this domain should be investigated in future mediational and longitudinal studies with the UPSA.     

Deciding Between Work and Family: An Episodic Approach

This study examined work–family conflict decision‐making based on a within–person, episodic approach. Based on 274 episodes across 78 individuals, we investigated the frequency of decisions that result in work interference with family (WIF) versus family interference with work (FIW), as well as the relation of work and family situational variables and previous work–family conflict (WFC) episodes on those decisions. No difference in the frequency with which participants reported WIF episodes versus FIW episodes was observed. Results indicated that work/family role sender pressure, work/family instrumental support, work/family activity importance, work emotional support, and the direction of the previous WFC decision each predicted WFC decisions. Dominance analysis indicated that role sender pressure was the most important predictor. In addition, we compare and discuss within‐person variation with between‐person variation. Contributions of the study to work–family research and practice are discussed.     

Executive Attention: An Alternative Perspective on General Mental Ability,Performance, and Subgroup Differences

The validity‐adverse impact tradeoff associated with the relationships among general mental ability (GMA), ethnicity, and employee performance represents one of the most pressing concerns in organizational staffing. We conducted 4 studies with 273 bank employees and 197 university students designed to assess the extent to which executive attention (EA) and GMA predict simulation performance and supervisory ratings of performance. We also assess the extent to which measures of EA and GMA are associated with subgroup differences. Results indicate that, like GMA, EA positively predicts managerial simulation and supervisory ratings of performance. In addition, although reaching statistical significance in only 1 of our 4 studies, EA was generally associated with smaller subgroup differences than GMA, and meta‐analysis across our samples supports this reduced subgroup difference. Moreover, advantages of EA tend to increase as studies move from the laboratory with undergraduate students to a concurrent validation organizational setting with employees. We discuss implications for a theory‐based view of cognitive ability in employee selection and implications for managerial practice.     

Internetbasierte Gesundheitsinterventionen

Background

Internet-based health interventions can serve as a useful supplement to regular face-to-face therapy only if they are accepted by the clients.

Objective

This aim of the current study was to examine the attitudes and opinions of potential users on internet-based health interventions in Germany. This information could make a useful contribution to the development and promotion of measures which target their requirements.

Material and methods

To address this issue psychotherapy patients and persons on a waiting list for outpatient psychotherapy were interviewed about their attitudes towards internet-based interventions and compared with the results from a matched control group.

Results

Compared with the control group, waiting list candidates in particular declared a reduced interest in engaging in internet-based interventions and both patient groups perceived few advantages. All groups appreciated the enhanced flexibility associated with internet-based interventions, but both patient groups thought that the increased anonymity and reduced inhibition threshold for seeking treatment were less advantageous than the control group. Compared to the controls, both patient groups worried more about privacy issues and a possible misinterpretation of their written statements. Both patient groups considered internet-based psychotherapy as conceivable for the treatment of fewer kinds of psychopathological symptoms than the control group. Patients considered that internet-based treatment of panic disorder, posttraumatic stress disorder, depression and generalized anxiety disorder was least imaginable although, to date, relatively many internet-based options are available for these disorders. There appears to be interest in the treatment of sexual dysfunctions through the internet.

Conclusion

To address the reservations concerning privacy protection, paper and pencil registration procedures could be provided. In addition, by clearly emphasizing that there is the possibility of establishing personal contact to a therapist either face to face or by video conference, internet-based services could also be more useful in satisfying patient needs.

     

Distraction During Deployment: Marital Relationship Associations With Spillover for Deployed Army Soldiers

Military spouses often have concerns regarding the impact of their communication on soldiers during deployment. However, literature is mixed regarding how communication between soldiers and spouses may impact soldiers’ self-reported work functioning during deployment, suggesting the need to evaluate moderating factors. In the current study, 3 relationship factors (marital satisfaction, conflictual communication, and proportion of conversation focused on problems) were tested as moderators of communication frequency and negative marriage-to-work spillover for soldiers. Whereas the 3 relationship factors were independently related to negative spillover, none significantly moderated the relationship between communication frequency and spillover. The overall pattern of results suggests that (a) lower marital satisfaction, a focus on problems during communication, and conflictual communication are each strongly linked to spillover for deployed soldiers; and (b) military couples may be self-restricting deployment communication frequency when experiencing less marital satisfaction and higher rates of negative communication. Implications for communication during deployment are discussed.     

Examining legalism,scrupulosity, family perfectionism,and psychological adjustment among LDS individuals

This study examined the relationships and interactions between legalism, scrupulosity, family perfectionism, guilt, and shame among 421 Latter-Day Saints (LDS or Mormons). The results showed that scrupulosity fully mediated the links between legalism and guilt, as well as legalism and shame. A moderated-mediation effect was found, in which family discrepancy (maladaptive perfectionism) intensified the scrupulosity–shame association in the mediation model of legalism and shame by scrupulosity. Family discrepancy was not a significant moderator for the mediation model of legalism and guilt by scrupulosity. Additional results are provided and implications of these findings are outlined.     

Hallucination And Imagination

What are hallucinations? A common view in the philosophical literature is that hallucinations are degenerate kinds of perceptual experience. I argue instead that hallucinations are degenerate kinds of sensory imagination. As well as providing a good account of many actual cases of hallucination, the view that hallucination is a kind of imagination represents a promising account of hallucination from the perspective of a disjunctivist theory of perception like naïve realism. This is because it provides a way of giving a positive characterisation of hallucination—rather than characterising hallucinations in negative, relational, terms as mental events that are subjectively indistinguishable from veridical perceptual experiences.
