Neurocognitive impairment does not predict treatment outcome in obsessive-compulsive disorder

There is conflicting evidence pertaining to whether or not neurocognitive task performance at baseline predicts treatment response in obsessive-compulsive disorder (OCD). In the present study, we administered a set of executive neurocognitive tests with a putative sensitivity for treatment outcome to a sample of 138 OCD patients. Additionally, subjective neurocognitive dysfunction was determined via a questionnaire. All patients participated in a cognitive-behavioural treatment program (CBT). Results showed that responders (n = 73) did not differ from non-responders (n = 65) on any of the parameters except for decreased performance on the delayed alternation test (p < .1, effect size: .61). A subsidiary analysis revealed that slowing on the Trail-Making Test A and an enhanced rate of perserveration errors on the Wisconsin Card Sorting Test predicted poor outcome for the treatment of compulsions. It is concluded that neurocognitive impairment does not represent a reliable early warning sign for non-response to CBT.     

Psychosozialer Versorgungsbedarf bei Arbeitnehmern

Zusammenfassung  Untersuchungen zu Häufigkeit, Verlauf und Ursachen psychischer Erkrankungen bei Arbeitnehmern sind rar. Die Gründe hierfür liegen sowohl auf Seiten der Arbeitsmedizin, die psychosoziale Aspekte wenig berücksichtigt, als auch bei der Psychotherapie, die zu wenig auf die Arbeitssituation eingeht. Die wenigen aussagekräftigen Untersuchungen legen bei Arbeitnehmern eine ähnlich hohe Prävalenz und Behandlungsbedürftigkeit nahe wie in der Allgemeinbevölkerung. Von den Folgen einer störungsinadäquaten Therapie psychischer Erkrankungen sind Arbeitnehmer in besonderem Maße betroffen, da die Erkrankungen nicht nur zu erheblichem persönlichem Leid führen, sondern durch Chronifizierung zu enormen Kosten in der medizinischen Versorgung beitragen. Außerdem sind sie durch krankheitsbedingte Fehlzeiten und (Früh-)Berentungen auch die Ursache weit reichender Produktionsausfälle in der Wirtschaft. Obwohl eine Reihe von Maßnahmen der betrieblichen Gesundheitsförderung zur Besserung der psychischen Befindlichkeit von Arbeitnehmern verfügbar sind, werden sie gegenwärtig noch zu selten eingesetzt und noch weniger evaluiert.

When “decoy effect” meets gender bias: The role of choice set composition in hiring decisions

A large body of research has found evidence that hiring decisions are frequently subject to strong gender bias and has explored factors that help to predict and prevent such a bias from occurring. In this paper, we explore a novel factor that has received only little attention: the composition of the choice set. Drawing on prior research on the attraction effect of decoys in consumer choice and personnel decisions, we posit that when decision makers need to decide whether to hire a male or a female applicant for a stereotypically male position, the presence of a third applicant whose profile is asymmetrically dominated by one of the two applicants can in many circumstances strongly increase the odds that the male applicant will be selected, but will not be beneficial for the female applicant. We test our hypotheses in five experimental studies with different designs, experimental settings, and participant pools—including managers with professional experience in hiring decisions. Our results provide robust evidence demonstrating the strong effects of choice set composition on the emergence of gender bias. In addition, we found that the presence of asymmetrically dominated applicants makes decision makers more confident in their biased decisions and more likely to implement them immediately without searching for further information. Finally, our results also provide some initial evidence that our results for stereotypically male positions will be reversed when hiring decisions are made for stereotypically female positions where the presence of decoys instead gives an advantage to female over male applicants.     

The challenge of merging: merger patterns, premerger status, and merger support

Employees of merging organizations often show resistance to the merger. The employees' support depends on the companies' premerger status and on the merger pattern. Based on an intergroup perspective, three studies were conducted to investigate the influence of premerger status (high, low) and merger pattern (assimilation, integration-equality, integration-proportionality, transformation) on participants' support for a pending organizational merger. Students (Study 1) and employees (Study 2) had to take the perspective of employees of a fictitious merging organization. Study 3 investigated students' perceptions of a potentially pending university merger using a 2 (status) x 3 (merger pattern: assimilation, integration-equality, integration-proportionality) design. Across all studies, the low-status group favored integration-equality and transformation whereas the high-status group preferred integration-proportionality and assimilation. Perceived threat mediated the effects. Legitimacy was a stronger mediator for effects of the low-status group.     

The haptic Müller-Lyer illusion in sighted and blind people

We examined the effect of visual experience on the haptic Müller-Lyer illusion. Subjects made size estimates of raised lines by using a sliding haptic ruler. Independent groups of blind-folded-sighted, late-blind, congenitally blind, and low-vision subjects judged the sizes of wings-in and wings-out stimuli, plain lines, and lines with short vertical ends. An illusion was found, since the wings-in stimuli were judged as shorter than the wings-out patterns and all of the other stimuli. Subjects generally underestimated the lengths of lines. In a second experiment we found a nonsignificant difference between length judgments of raised lines as opposed to smooth wooden dowels. The strength of the haptic illusion depends upon the angles of the wings, with a much stronger illusion for more acute angles. The effect of visual status was nonsignificant, suggesting that spatial distortion in the haptic Müller-Lyer illusion does not depend upon visual imagery or visual experience.     

High in the hierarchy: How vertical location and judgments of leaders’ power are interrelated

Leadership implies power. We argue, from a social embodiment perspective, that thinking about power involves mental simulation of vertical location. Three studies tested whether judgments of leaders’ power and information on a vertical location are interrelated. In Studies 1a–1c, participants judged a leader’s power after being presented with, among other information, an organization chart containing either a long or a short vertical line. A longer vertical line increased judged power. Study 2 showed that this effect persists when longer (vs. shorter) vertical lines are presented in an independent priming task and not in an organization chart, and that horizontal lines do not have the same effect. Finally, Studies 3a and 3b showed the reverse causal effect: information about a leader’s power influenced participants’ vertical positioning of a leader’s box in an organization chart and of a leader picture into a team picture. Implications for leadership communication are discussed.     

Stress modulates the use of spatial versus stimulus-response learning strategies in humans

Animal studies provided evidence that stress modulates multiple memory systems, favoring caudate nucleus-based "habit" memory over hippocampus-based "cognitive" memory. However, effects of stress on learning strategy and memory consolidation were not differentiated. We specifically address the effects of psychosocial stress on the applied learning strategy in humans. We designed a spatial learning task that allowed differentiating spatial from stimulus-response learning strategies during acquisition. In 13 subsequent trials, participants (88 male and female students) had to locate a "win" card out of four placed at a fixed location in a 3D model of a room. Relocating one cue in the last trial allowed inferring the applied learning strategy. Half of them participated first in the "Trier Social Stress Test." Salivary cortisol and heart rate measurements were taken. Stressed participants used a stimulus-response strategy significantly more often than controls. Subsequent verbal report revealed that spatial learners had a more complete awareness of response options than stimulus-response learners. Importantly, learning performance was not affected by stress. Taken together, stress prior to learning facilitated simple stimulus-response learning strategies in humans-at the expense of a more cognitive learning strategy. Depending on the context, we consider this as an adaptive response.
