Motivation for work among non-working disabled people in Norway in a life course perspective

The aim of this study is to analyze attitudes towards work among non-working disabled people and to address their motivation in a life course perspective. The background of the study is low employment rates among disabled people. One hypothesis is that a generous welfare system has disincentive effects because replacement rates of social security are too generous. Although the existing evidence is conflicting, some studies of inflow into benefits suggest that the welfare system may have such effects on people in their 50's and 60's. However these studies tend to draw general conclusions. The current article is based on a 2007 Norwegian dataset on the living conditions of disabled people (n = 1652). The findings suggest that age has a profound influence on motivation to work and is undoubtedly the most important predictor. Motivation to work among young disabled people tends to be strong but declines in later life. The substantial age effects are discussed in terms of the experience of exclusion and the availability of alternative social roles. The implication for interpretations of disincentive research is that caution must be exercised when suggesting general conclusions about disincentives based on research examining individuals who are in the final phase of a typical working career.

Mental health: market power and governance

This paper is concerned with the pricing behaviour of providers of residential care for people with mental health problems. Two aspects of pricing were considered. First, are there differences between providers' market power and their actual mark-up rates (e.g. due to differences in motivation)? Second, do the different governance arrangements used in sectors of the industry, such as unified public and non-profit organisation and private bilateral contracting, affect pricing behaviour? A theoretical model was developed to underpin the empirical analysis of 496 residents in 112 mental health care facilities. Private, bilateral organisation was found to be associated with comparatively lower potential price-cost mark-up but a greater propensity to use this power to make profits/surpluses.     

Exposure of mice to a predator odor increases acoustic startle but does not disrupt the rewarding properties of VTA intracranial self-stimulation

The present investigation assessed the propensity of an acute psychogenic stressor exposure to induce behavioral change in paradigms assessing fear/anxiety (acoustic startle) and motivation/anhedonia (intracranial self-stimulation) in CD-1 mice. In the acoustic startle paradigm, a 10-min exposure of 2-4 month old mice (young adult mice) to fox odor (2,5-dihydro-2,4,5-trimethylthiazoline; TMT) was associated with decreased acoustic startle relative to mice exposed to the control odor, butyric acid (BA), immediately and relative to both saline and BA exposure 24 h following odor exposure in the home cage. In contrast, a 2-min exposure of young adult mice to TMT was associated with an increase in startle relative to saline and BA during the immediate post-odor test session only. In young adult mice a 2-min and a 10-min exposure to BA resulted in a startle profile of mice reminiscent of saline-treated mice. In comparison to young adult mice, a 2-min exposure of mature adult mice (5-7 months old) to TMT enhanced startle for up to 48 h relative to both saline and BA, while a 10-min exposure of mature adult mice to TMT enhanced startle for 168 h post-odor exposure relative to saline-exposed mice only. However, the greatest increase in startle amplitude (i.e. 48 h) was acquired following the 2-min exposure of mature mice to TMT. Among mature adult mice, a 10-min exposure to BA in the home cage eventuated in enhanced startle relative to saline-exposed animals 168 h following odor exposure. In comparison, exposure of mice to 10 min of TMT depressed responding for VTA brain stimulation at the initial 80 Hz frequency, but was ineffective in elevating reward thresholds relative to mice merely exposed to saline. Mice assessed in the ICSS paradigm were approximately 2-4 months old at the time of surgery and 5-7 months old at the completion of testing. These data suggest that acute odor exposure may induce a fear gradient dependent upon the perceived stressor severity and that the resultant anxiety-like effects are dependent on the duration of odor exposure, age of the animals and the temporal interval between odor presentation and behavioral testing. Moreover, the anxiogenic properties of psychogenic stressors can be separated from their anhedonic effects. The implications of these data for clinical psychopathology are discussed.     

The use of the Pros and Cons of Anorexia Nervosa (P-CAN) Scale with children and adolescents

Objective: The Pros and Cons of Anorexia Nervosa (P-CAN) Scale was developed out of a previous qualitative study [Int J Eat Disord 25 (1999) 177] in which the positive and negative aspects of anorexia nervosa (AN) were elicited from individuals with AN. Principal components analysis was then used in an adult sample to reduce the number of items and to derive empirically and theoretically based subscales [Serpell et al., submitted]. The aim of the current study was to validate the P-CAN in children and adolescents with AN and compare the pros and cons of young people with AN with those of adults. Methods: Forty-eight young people with AN completed the P-CAN and the Eating Disorders Examination, a semistructured interview used to aid in the diagnosis of eating disorders. Results: Validity in younger patients appeared to be good. Children and adolescents showed both similarities and differences from adults tested in a previous study. Conclusions: The measure is the first to measure attitudes of children and adolescents with AN towards their illness and may prove a useful tool for the measurement of attitudes towards AN in both clinical and research settings.     

Implicit and explicit alcohol-related cognitions

This article presents the proceedings of a symposium at the 2001 RSA Meeting in Montreal, Canada organized by Reinout W. Wiers and Alan W. Stacy. The purpose of the symposium was to present recent applications of implicit cognitive processing theory to alcohol research. Basic cognitive research has demonstrated that implicit cognition influences memory and behavior without explicit recall or introspection. The presentations from this symposium show that implicit cognition approaches yield new insights into understanding drinking motivation. The presentations were: (1) An introduction by Alan W. Stacy; (2) Implicit cognition and alcohol use. Involvement of other variables? (Susan L. Ames); (3) Alcohol expectancies and the art of implicit priming (Jane A. Noll); (4) Parental alcoholism and the effects of alcohol on semantic priming (Michael A. Sayette); (5) Implicit arousal and explicit liking of alcohol in heavy drinkers (Reinout W. Wiers); and (6) Negative affective cues and associative cognition in problem drinkers (Martin Zack). Comments were provided by the discussant Marvin Krank. The presented studies demonstrated that: (1) implicit memories of alcohol associations are powerful predictors and cross‐sectional correlates of alcohol use; (2) implicit retrieval processes influence alcohol outcome expectancies and alcohol consumption; (3) alcohol consumption influences implicit memory processing; (4) heavy drinkers reveal different affective responses in implicit and explicit tasks; and (5) negative affect exerts an implicit priming effect for alcohol associations in problem drinkers. These findings illustrate the importance of implicit cognition in understanding alcohol abuse and demonstrate the potential of the theoretical framework for more widespread application across a variety of areas of alcohol research, including diagnostics for the risk of alcohol abuse, treatment, and prevention.     

Scalp recorded direct current potential shifts associated with quenching thirst in humans

As an indicator of cortical excitability, direct current (DC) potentials were recorded from thirsted subjects before, during and after drinking 400 ml of water. Self-rated thirst was distinctly reduced after drinking. Compared with control conditions in which the subjects remained thirsty, during drinking a widespread negative potential shift occurred averaging over -70 microV at Cz. At the transition from the consumatory phase to the postconsumption phase, a slow positive potential shift commenced that was most pronounced over the anterior cortex (averaging over +40 microV at Fz) and persisted for more than 3 min after drinking. Control conditions excluded muscle activity, ocular movements, and changes in body fluid and serum osmolality as possible non-neuronal sources of the DC-potential changes. The sequence of negative and positive potential shifts associated with drinking indicates a coordinate regulation of cortical excitability that may facilitate consumatory behavior and its context-dependent encoding into memory.     

Alterations in the behavioral effects of LSD by motivational and neurohumoral variables.

Forty naive male albino rats were trained to press a bar on a fixed-ratio (FR 32) schedule of water reinforcement. They were then divided into two groups, one of which (N = 20) received 5 min of extra water 12 hr before each experimental session; the other group (N = 20) received no extra water. Half of the animals in each group was given three daily doses (100 mg/kg) of the trytophan hydroxylase inhibitor p-chlorophenylalanine methyl ester (PCPA) while the remaining animals were given control injections of the PCPA vehicle. Ten days following the last administration of PCPA (or vehicle) all animals were given a low dose of LSD (20 mug/kg). Bar-pressing behavior was significantly disrupted only in those animals receiving both PCPA and extra water. Central (whold brain) concentrations of serotonin (5-HT) were significantly lower in all animals which had been treated with PCPA. These results, along with those previously reported, suggest that amount of deprivation can be an important determinant of both the ability of drugs to alter behavior and the dependence of such alterations upon underlying neuronal activity.
