Selected AbstractsWhat is learned from experience in a probabilistic environment?JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 3 2004Stephen E. Edgell Abstract Three experiments explored what is learned from experience in a probabilistic environment. The task was a simulated medical decision-making task with each patient having one of two test results and one of two diseases. The test result was highly predictive of the disease for all participants. The base rate of the test result was varied between participants to produce different inverse conditional probabilities of the test result given the disease across conditions. Participants trained using feedback to predict a patient's disease from a test result showed the classic confusion of the inverse error, substituting the forward conditional probability for the inverse conditional probability when tested on it. Additional training on the base rate of the test result did little to improve performance. Training on the joint probabilities, however, produced good performance on either conditional probability. The pattern of results demonstrated that experience with the environment is not always sufficient for good performance. That natural sampling leads to good performance was not supported. Further, because participants not trained on joint probabilities did, however, know them but still committed the confusion of the inverse error, the hypothesis that having joint probabilities would facilitate performance was not supported. The pattern of results supported the conclusion that people learn all the necessary information from experience in a probabilistic environment, but depending upon what the experience was, it may interfere with their ability to recall to memory the appropriate sample set necessary for estimating or using the inverse conditional probability.

Sarro Abstract In humans, auditory perception reaches maturity over a broad age range, extending through adolescence. Despite this slow maturation, children are considered to be outstanding learners, suggesting that immature perceptual skills might actually be advantageous to improvement on an acoustic task as a result of training (perceptual learning). Previous non-human studies have not employed an identical task when comparing perceptual performance of young and mature subjects, making it difficult to assess learning. Here, we used an identical procedure on juvenile and adult gerbils to examine the perception of amplitude modulation (AM), a stimulus feature that is an important component of most natural sounds. On average, Adult animals could detect smaller fluctuations in amplitude (i.e., smaller modulation depths) than Juveniles, indicating immature perceptual skills in Juveniles. However, the population variance was much greater for Juveniles, a few animals displaying adult-like AM detection. To determine whether immature perceptual skills facilitated learning, we compared naïve performance on the AM detection task with the amount of improvement following additional training. The amount of improvement in Adults correlated with naïve performance: those with the poorest naïve performance improved the most. In contrast, the naïve performance of Juveniles did not predict the amount of learning. Those Juveniles with immature AM detection thresholds did not display greater learning than Adults. Furthermore, for several of the Juveniles with adult-like thresholds, AM detection deteriorated with repeated testing. Thus, immature perceptual skills in young animals were not associated with greater learning. © 2010 Wiley Periodicals, Inc.

McCann Abstract Title., Subjective side effects of antipsychotics and medication adherence in people with schizophrenia. Aim., This paper is a report of a study conducted to describe the prevalence of antipsychotic medication side effects in individuals with schizophrenia, and to assess if a relationship existed between side effects and medication-taking. Background., Non-adherence to antipsychotics is common in people with schizophrenia. There is a direct relationship between non-adherence and relapse, but it is unclear if an association exists between side effects and non-adherence. Method., The Liverpool University Neuroleptic Side-effect Rating Scale was used with a convenience sample of 81 mental health service users with schizophrenia. Participants were recruited from one urban and one rural area in Australia in 2004. Data were analysed using Statistical Package for Social Science and nonparametric statistical methods based on the nature of data. Findings., Around 20% of participants had missed taking their medication at least once in the week before data collection. About half experienced one or more side effects, but the level of accumulated side effects was not associated with medication omission. Older participants were more likely to experience anticholinergic and allergic side effects than their younger counterparts. Younger women were more likely to experience hormone-related side effects than older women. Overall, medication omission was not statistically significantly correlated with any of the seven Liverpool University Neuroleptic Side-effect Rating Scale subscales. Conclusion., Greater attention needs to be paid to age- and gender-specific side effects and to monitoring side effects in people prescribed atypical medication antipsychotics. Service users, case managers and prescribers may need additional training to assist them to identify side effects and to take steps to ameliorate or at least minimize their effects.

Chadwick Background, There is scant research on the subject of dysphagia and people with intellectual disabilities. This study explores the barriers which caregivers believe make following Speech and Language Therapists' (SLTs) dysphagia management strategies more difficult. Method, Semi-structured open-ended interviews were conducted with 46 caregivers who supported 40 intellectually disabled adults with dysphagia. Results, Caregivers perceived particular difficulties in modifying food and drinks to safe consistencies, achieving the agreed positioning during mealtimes, and in using support and prompting strategies. Problematic support and prompting strategies included difficulties with pacing correctly; facilitating people to adequately relax and concentrate; observing and prompting people to pace suitably and take safe amounts of food and drink in each mouthful. Additional barriers identified included time pressures, staff turnover and insufficient reviewing of SLT management strategies by caregivers. Conclusions, Findings suggest that additional training and monitoring is required to ensure caregivers are aware of their role and responsibility in promoting safe oral intake for adults with dysphagia and intellectual disabilities. Ongoing support is suggested for people with intellectual disabilities and dysphagia to help them understand the reasoning behind management strategies.

The value of the SPP from the perspectives of parent participants and tutors was examined in focus groups and telephone interviews. Data were analyzed using framework analysis. Parents perceived a commonality of emotions and practical issues, valued meeting similar others, felt less isolated, more positive, motivated, and more calm; some had found the "real me again." Changes were attributed to techniques learned. Parents were anxious of being cast adrift at the end of SPP. Tutors needed more support and additional training around child protection and confidentiality. © 2008 Wiley Periodicals, Inc. [source] Training subspecialty nurses in developing countries: Methods, outcome, and costPEDIATRIC BLOOD & CANCER, Issue 2 2003Judith A. Wilimas MD Abstract Background As infections are controlled in developing countries, other pediatric subspeciality programs such as oncology become increasingly important. A major impediment to the development of such programs is a lack of trained nurses. Therefore, education of pediatric subspecialty nurses becomes a priority. Procedure We describe three models we have used for education of pediatric oncology nurses: a short series of classes or lectures with additional training of key nurses, an expanded 12 week series of classes at centers combining didactic and clinical instruction and a regional residential school offering regular 12 week courses in theory and clinical practice. Results Cost analysis showed that the cost per nurse trained was, respectively, $3,700; $4,350; and $5,500. Early effectiveness indicators show that retention rates are high, home institutions are satisfied, and nurses trained shared their knowledge with other nurses and improved nursing practices. Conclusions Programs to teach subspecialty nursing in developing countries are effective and can improve medical care. Such programs should be based on past experience and evaluated as to cost and effectiveness. Med Pediatr Oncol 2003;41:136,140. © 2003 Wiley-Liss, Inc. [source] Occupational blood exposure among unlicensed home care workers and home care registered nurses: Are they protected?AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 7 2009FAAN, J. Lipscomb PhD Abstract Background Little is known about the risk of blood exposure among personnel providing care to individual patients residing at home. The objective of this study was to document and compare blood exposure risks among unlicensed home care personal care assistants (PCAs) and home care registered nurses (RNs). Methods PCAs self-completed surveys regarding blood and body fluid (BBF) contact in group settings (n,=,980), while RNs completed mailed surveys (n,=,794). Results PCAs experience BBF contact in the course of providing care for home-based clients at a rate approximately 1/3 the rate experienced by RNs providing home care (8.1 and 26.7 per 100 full time equivalent (FTE), respectively), and the majority of PCA contact episodes did not involve direct sharps handling. However, for PCAs who performed work activities such as handling sharps and changing wound dressings, activities much more frequently performed by RNs, PCAs were at increased risk of injury when compared with RNs (OR,=,7.4 vs. 1.4) and (OR,=,6.3 vs. 2.5), respectively. Conclusion Both PCAs and RNs reported exposures to sharps, blood, and body fluids in the home setting at rates that warrant additional training, prevention, and protection. PCAs appear to be at increased risk of injury when performing nursing-related activities for which they are inexperienced and/or lack training. Further efforts are needed to protect home care workers from blood exposure, namely by assuring coverage and enforcement of the Occupational Safety and Health Administration (OSHA) Bloodborne Pathogen Standard [Occupational Safety and Health Administration. 1993.
