Fitts’ Law as a Function of System Dynamics and Target Uncertainty

Fitts’ law was found to hold for discrete movements executed by subjects controlling the velocity of a cursor with a control stick. The slope of movement time versus index of difficulty was approximately twice as large as for a comparable position control system. Target uncertainty also increased the slope of total time versus index of difficulty, and this effect is interpreted in terms of adaptive tuning of the human movement system.     

The Schematic Representation of Effector Function Underlying Perceptual-Motor Skill

Conceptual and methodological problems related to Schmidt’s (1975) motor schema theory are discussed. In particular, the motor schema is interpreted as representing the dynamics of the system being controlled, which may or may not be associated with a referent movement pattern. Furthermore, it is suggested that prior familiarity with a control system’s dynamics is a critical but uncontrolled factor in tests of the theory, and largely accounts for their equivocal findings. These ideas are examined by two experiments in which subjects had to bimanually control the movement of a computer-displayed cursor along a track on a CRT screen. Different track orientations required different patterns of movement not entailing a single generalized motor program. Experiment 1 shows that variable track performance with a given control system, results in better transfer to novel tracks than does fixed practice. Experiment 2 demonstrates that altering the control system disrupts performance whether or not the required movements remain the same. These results indicate the need for a fundamental modification of schema theory, such that a schematic representation of effector-environment relations (effector function) is available independently of particular movement patterns used in its acquisition.     

Ethically Questionable Behaviors Among Supervisees: An Exploratory Investigation

In spite of numerous studies of program outcomes finding little or no positive effect on violent behavior, the Duluth model remains the most common program type of interventions with perpetrators of domestic violence. In addition, Duluth model programs often ignore serious mental health and substance abuse issues present in perpetrators. These and other issues of possible threat to mental health professional ethics are reviewed in light of the court-mandated, compulsory nature of most Duluth model programs and client and victim expectations for program efficacy.     

An Exploratory Study: Perceptions of Ethical Behaviors Among Psychologists Practicing in the Caribbean

A sample of 44 psychologists who practice in the Caribbean completed a web-based survey containing 73 behavioral items related to ethical issues in professional practice. The aim of this exploratory study was to learn about perceptions regarding ethical behaviors that create ethical dilemmas and the level of agreement to their responses and to identify how demographic variables influenced their perceptions of ethical behaviors. Findings suggest that there was approximately an equal level of agreement on behaviors such as being an advocate for your client and being sexually involved with a current client rated as ethical and unethical, respectively. Several demographic variables and ethical behaviors such as level of degree and confidentiality issues were statistically significant. Finally, psychologists prefer the presence of a professional psychological association with an ethics committee.     

The Development of a Code for Australian Psychologists

Section 35(1)(c) of the Health Practitioner Regulation National Law Act (2009 Health Practitioner Regulation National Law Act of 2009. (Queensland).  [Google Scholar]) requires the newly formed Psychology Board of Australia (PsyBA) “to develop or approve standards, codes and guidelines.” In 2010 the PsyBA decided to initially adopt the Australian Psychological Society's (APS) Code of Ethics (2007 Australian Psychological Society. 2007. Code of ethics, Melbourne, , Australia: Author.  [Google Scholar]) and develop a new code in the future with the involvement of key stakeholders without deciding what the nature of this code will be. The PsyBA now has to decide exactly how it will proceed in future. My aim in this article is to examine the options available to the PsyBA by exploring the definition and function of codes; presenting a history of the APS Code; and considering approaches that had been followed in Europe, Israel, New Zealand, and South Africa.     

Compassion satisfaction,compassion fatigue,and burnout in a national sample of trauma treatment therapists

Abstract

For behavioral health professionals working with traumatized clients, continuous and prolonged exposure to the stress of working with the myriad of trauma-related stressors experienced by their clients can lead to various responses including burnout, compassion fatigue, and compassion satisfaction. The present study investigates the impact of using evidence-based practices on compassion fatigue, burnout, and compassion satisfaction in a random, national sample of self-identified trauma specialists (N=532). The 30-item Professional Quality of Life Scale (Stamm, 2005) and the 19-item Trauma Practices Questionnaire (Craig & Sprang, 2009) were included in a survey to licensed social workers and psychologists from professional membership rosters. Age and years of experience proved to be powerful predictors of only two of the three criterion variables, with younger professionals reporting higher levels of burnout and more experienced providers endorsing higher levels of compassion satisfaction. The utilization of evidence-based practices predicted statistically significant decreases in compassion fatigue and burnout, and increases in compassion satisfaction. The utility of these findings in understanding the process of trauma transmission between therapist and client as well as directions for future research are discussed.     

Evaluation of the Delayed Discovery Case

Summary

In this chapter, practicing lawyer Michael S. Morey guides the reader through the complex legal and non-legal issues involved in evaluating whether legal action should be pursued on behalf of an adult survivor of childhood sexual abuse. After analyzing how evaluation of sexual abuse cases differs from that in most other personal injury cases, he presents a model for non-suggestive yet thorough client interviewing and case evaluation to help both survivor and lawyer decide whether to pursue litigation. Viability of a case, determined by three critical legal issues, does not necessarily mean litigation ought to be pursued, and he explores how to make the initial interview a valuable resource to survivors, whether or not legal action is ultimately sought, with practical tips and a reproducible intake form.     

Domestic Violence Service Providers’ Technology Readiness and Information Needs

Technology-based applications hold promise as effective, efficient means of disseminating research- and practice-based information to professionals whose work relates to domestic violence. Other related uses of technology in the field have grown, including safety planning to address technology-related risks to victims and software programs being integrated into domestic violence agencies. However, to date, the levels of technology readiness and technology-related information needs of these professionals have received minimal research attention. This study involved a national survey of 471 professionals whose work addresses domestic violence. The findings demonstrate differences in professionals’ technology readiness based on key demographic and professional characteristics. They also reveal the most frequently noted information needs within this professional field. Implications for future research and practice are provided.     

A Therapist‐Assisted Internet‐Based CBT Intervention for Posttraumatic Stress Disorder: Preliminary Results

Posttraumatic stress disorder (PTSD) is a debilitating mental health condition frequently associated with psychiatric comorbidity and diminished quality of life, and it typically follows a chronic, often lifelong, course. Previous research has shown that trauma‐related psychopathology (but not necessarily clinical PTSD) can be effectively treated via the Internet. This study is the first of its kind to report on the online treatment of patients with a Diagnostic and Statistical Manual of Mental Disorders (fourth edition) clinical diagnosis of PTSD with therapist support by e‐mail only. Preliminary findings are presented of an open trial involving a 10‐week Internet‐based therapist‐assisted cognitive behavioural treatment for PTSD (PTSD Online). Pre and posttreatment measures of PTSD and related symptomatology were compared for 16 participants with a variety of trauma experiences. Participants showed clinically significant reductions in PTSD severity and symptomatology, moderate tolerance of the program content, and high therapeutic alliance ratings. No significant change was found on measures of more general psychological symptoms. The results suggest that PTSD Online appears to be an effective and accessible clinical treatment for people with a confirmed PTSD diagnosis.     

Issues in Publicly Subsidized Long Term Care Systems and Implications for the Religous Sector

Given the increasing numbers of elderly in need of long term care services and the harsh reality of finite resources, new models are required which define those elderly persons who should remain eligible for publicly subsidized long term care. If, in fact, a method is established for serving only a limited number of older persons, i.e., the truly vulnerable elderly, by way of the public system of long term care, a large constituency of older Americans will be left to exist on the margins. The church as an informal care system may appropriately assume the role of ensuring that the available public funds are used wisely and that service gaps inevitably left bewteen the increasing number of older persons and shrinking public support are bridged. In addition, the church must assist in improving all long term services by contributing to public policy formation.
