ANTICIPATED EFFECTS OF ALCOHOL CONSUMPTION AS A FUNCTION OF BEVERAGE TYPE: A CROSS-CULTURAL REPLICATION

The relation between type or form of alcoholic beverage consumed and expectations about emotional or behavioral concomitants of drinking was investigated. One hundred and thirty-four Finnish undergraduates (45 men and 89 women) with a mean age of 20.9 years were administered a survey inquiring about the association between each of 86 feelings or actions and four categories of alcoholic beverage (beer, wine, mixed drinks, and straight drinks), assuming comparable levels of intoxication. Multiple discriminant analyses indicated that distinctive and stable expectancies were associated with beer (tension reduction), wine (social pleasure), and straight drinks (mainly negative consequences often related to heavy drinking), while expectancies for mixed drinks were shared by other beverage types. These findings replicated and extended those obtained with a U.S. sample.     

Learning and reminiscence as a function of target predictability in a two-dimensional tracking task

Twenty subjects performed one of two types of a two-dimensional tracking task for two 5-min sessions, separated by a 10-min rest. In task I, both the horizontal and the vertical components of target movement were unpredictable. In task II, the horizontal component of target movement was predictable (sinusoidal), while the vertical movement was unpredictable. There was no change in level of performance throughout the 10 min of practice on task I. For task II's predictable component, there were marked within- and between-session improvements in performance; whereas for the unpredictable component there was only a between-session improvement. It is proposed that, in these tracking tasks, improvement with practice depends on the development of programmed sequences of movement which can only occur for predictable target movements. Only after a rest do these programmed sequences become automatic, releasing spare attentional capacity for improving the performance of any unpredictable components of the task.     

Virtual reality exposure therapy and standard (in vivo) exposure therapy in the treatment of fear of flying

This controlled clinical trial tested virtual reality exposure (VRE) therapy for the fear of flying (FOF), a relatively new and innovative way to do exposure therapy, and compared it to standard (in vivo) exposure therapy (SE) and a wait list (WL) control with a 6- and 12-month follow-up. Eighty-three participants with FOF were randomly assigned to VRE, SE, or WL. Seventy-five participants, 25 per group, completed the study. Twenty-three WL participants completed randomly assigned treatment following the waiting period. Treatment consisted of 4 sessions of anxiety management training followed either by exposure to a virtual airplane (VRE) or an actual airplane at the airport (SE) conducted over 6 weeks. Results indicate that VRE was superior to WL on all measures, including willingness to fly on the posttreatment flight (76% for VRE and SE; 20% for WL). VRE and SE were essentially equivalent on standardized questionnaires, willingness to fly, anxiety ratings during the flight, self-ratings of improvement, and patient satisfaction with treatment. Follow-up assessments at 6 and 12 months indicated that treatment gains were maintained, with more than 70% of respondents from both groups reporting continued flying at follow-up. Based on these findings, the use of VRE in the treatment of FOF was supported in this controlled study, suggesting that experiences in the virtual world can change experiences in the real world.     

Relations between psychopathy facets and externalizing in a criminal offender sample

The construct of psychopathy is viewed as comprising distinctive but correlated affective-interpersonal and social deviance facets. Here, we examined these facets of Hare's Psychopathy Checklist-Revised (PCL-R) in terms of their associations with the externalizing dimension of adult psychopathology, defined as the common factor underlying symptoms of conduct disorder, adult antisocial behavior, alcohol use/abuse, and drug abuse, along with disinhibitory personality traits. Correlational analyses revealed a strong relationship between this externalizing dimension and the social deviance facet of psychopathy (r = .84), and a lesser relationship with the emotional-interpersonal component (r = .44). Structural models controlling for the moderate overlap between the PCL-R factors revealed that externalizing was substantially related to the unique variance in the social deviance features of psychopathy, but unrelated to the unique variance of the emotional and interpersonal features whether modeled together or as separate factors. These results indicate that the social deviance factor of the PCL-R reflects the externalizing dimension of psychopathology, whereas the emotional-interpersonal component taps something distinct aside from externalizing. In addition, based on our finding of an association between PCL-R social deviance and externalizing, we were able to predict new relations between this facet of psychopathy and criterion variables, including nicotine use and gambling, that have previously been linked to externalizing. Implications for future research on the causes and correlates of psychopathy are discussed.     

Fear imagery and the startle-probe reflex

Blink reflexes to acoustic probes, heart rate, and subjective reports were studied during affective memory imagery. Thirty-six undergraduates memorized 6 pairs of neutral and fearful sentences. After learning each pair, they relaxed and listened to a series of uniform tones, one every 6 s. A change in tone pitch (higher or lower) cued recall of one of the two sentences. At the first cue tone, groups (n = 12) were under different instructions: (a) ignore the sentence and relax, (b) silently articulate the sentence, and (c) imagine the sentence content as a personal experience. At the second cue tone, all subjects performed the imagery task. Startle probes (50-ms, 95-dB white noise) were presented unpredictably during relaxation and recall trials. Probe blink reflexes were larger and cardiac rate faster at fear sentence recall than at neutral sentence recall or relaxation. For probe reflexes, this effect was greater for imagery than for nonsemantic recall tasks.     

Employees' Political Skill and Job Performance: An Inverted U‐Shaped Relation?

During the past decade, the construct of political skill has attracted a lot of attention. In particular, its relation to job performance has been examined. With regard to this link, it is typically proposed that political skill affects job performance in a positive linear manner. However, in this article it is suggested that intermediate levels of employees' political skill yield the highest job performance, implying that this association is in fact represented by an inverted U‐shape. Findings from two field studies (N₁ = 178, N₂ = 115 employee‐supervisor‐colleague triads) that incorporated different sample characteristics (early career employees, established employees), job performance dimensions (overall, task, contextual, and adaptive performance), and rating sources (supervisors and colleagues) supported this idea. Across different analyses, employees with intermediate levels of political skill received higher job performance ratings compared to those with lower and higher levels, respectively. In addition, the nature of the relationships between employees and their raters was found to moderate this curvilinear effect. Specifically, besides the fact that employees who had close working relationships with their raters generally received higher job performance ratings, the decreases in the job performance ratings of employees high in political skill were less pronounced when they had close relationships.
