Movement analysis in the early detection of newborns at risk for developing spasticity due to infantile cerebral palsy

In order to limit the consequences of infantile cerebral palsy (ICP), physiotherapy should start as early as possible. This requires that infants at risk are detected at the earliest age possible. Today, diagnosis is based on visual observation by physicians and as such is influenced by subjective impressions. Objective methods, quantifying the pathological deviation from normal spontaneous motor activity would be preferable as they, for example, allow an inter- and intra-individual comparison of movement. In this paper we have developed a methodology that allows the 3-dimensional acquisition of unconstrained movement in newborn babies, using a motion analysis system. From the recorded movement data we have extracted 53 quantitative parameters that describe the differences between healthy and affected participants. Considered individually, each of these parameters does not permit a conclusive statement to be made as to whether or not the patient is at risk. Cluster analysis based on Euclidian distances therefore has been used to find an optimal combination of eight parameters. The optimal combination has been subsequently applied to organize the participants' movement into preferably homogeneous classes labelled "healthy" or "at risk". Classification was performed utilising quadratic discriminant analysis. The methodology presented allows a reliable discrimination between healthy and affected participants. Overall detection rate reached 73%. This value is expected to rise with increasing patient and norm collective database size.     

Antihypertensive treatment,compliance, and quality of life: Review of a little-understood relation

If patients notoriously violate treatment regimens known to effectively control hypertension, then there must be some subjective costs associated with adherence to these regimens. Generally speaking, there must be some reduction in quality of life associated with antihypertensive medication. Unfortunately the concept of quality of life, due to its lack of specificity, is of little help in further investigating the nature of these subjective costs. We developed a simple neuropsychophysiological model based on fundamental psychological and physiological processes: corticoinhibitory effects of phasic blood pressure elevation reduce the aversive or painful qualities of many stressors. This negative reinforcement increases the rate of the reinforced physiological behavior, i.e., phasic analgesic blood pressure increases. Such negatively reinforced operant behavior is known to be extremely resistant to extinction. Counter actions such as taking antihypertensive medication not only lead to reduced quality of life due to their cancellation of the analgesic effect of conditioned blood pressure increase, but also lead to some form of reluctance to comply with treatment. The model not only provides an innovative etiological path to the emergence of neurogenic essential hypertension, but also yields a highly specific and lean concept of quality of life. Furthermore, it supplies the health care community with a concise explanation for the well-known low compliance of patients with their antihypertensive regimens. In addition to its parsimony, the model fits well with various experimental findings and has been operationalized and tested empirically. Specific therapeutic implications can be derived.     

Exploring the nature of cognitive flexibility

Cognitive flexibility is an important characteristic that helps humans pursue complex tasks, such as multitasking and finding novel, adaptable solutions to changing demands. Yet it is still a poorly understood construct. After briefly reviewing several investigations of this construct in cognitive science, I propose a unified account that considers cognitive flexibility a property of the cognitive system, rather than a cognitive skill. The emergence of cognitive flexibility is dependent on two kinds of interactions: the interaction of several cognitive mechanisms, and the interaction of sensorimotor mechanisms, cognition, and context in developmental time. The quest for a comprehensive and unified account of cognitive flexibility is highly justified given its potential usefulness in fostering efficient problem solving and creativity.     

Bedrohungsszenarien und Gewalt gegenüber Dritten in der Psychotherapie

Aggressive behaviour, violent fantasies and potential threats against third parties are frequent topics in psychotherapy. Clinical, social and dynamic factors have to be considered for the risk assessment of aggressive behaviour. The appearance of aggressive fantasies and threats can be perceived as an indicator for potential threats. Legal aspects such as medical confidentiality, rights and duties to warn have to be kept in mind when dealing with threats against third parties. Concerning threats against children different laws have to be considered.     

Corporate Teamwork and Diversity Statements in College Recruitment Brochures: Effects on Attraction1

Organizations are increasingly emphasizing group work or teamwork as a source of competitive advantage in a diverse workforce. It has been suggested that such organizations must target their recruitment efforts at applicants who are both diverse and amenable to working in teams. Data were collected from 181 undergraduates at a large northeastern university who viewed a recruitment brochure of a fictitious firm in which statements about teamwork and diversity were manipulated. Results indicate that applicants' teamwork attitude moderated the relationship between teamwork statements and applicant attraction to the organization. Minority and gender status moderated the relationship between diversity statements and applicant attraction. These results provide evidence that organizations can target specific applicant characteristics with appropriate statements in recruitment brochures.     

Effects of proactive interference on non-verbal working memory

Working memory (WM) is a cognitive system responsible for actively maintaining and processing relevant information and is central to successful cognition. A process critical to WM is the resolution of proactive interference (PI), which involves suppressing memory intrusions from prior memories that are no longer relevant. Most studies that have examined resistance to PI in a process-pure fashion used verbal material. By contrast, studies using non-verbal material are scarce, and it remains unclear whether the effect of PI is domain-general or whether it applies solely to the verbal domain. The aim of the present study was to examine the effect of PI in visual WM using both objects with high and low nameability. Using a Directed-Forgetting paradigm, we varied discriminability between WM items on two dimensions, one verbal (high-nameability vs. low-nameability objects) and one perceptual (colored vs. gray objects). As in previous studies using verbal material, effects of PI were found with object stimuli, even after controlling for verbal labels being used (i.e., low-nameability condition). We also found that the addition of distinctive features (color, verbal label) increased performance in rejecting intrusion probes, most likely through an increase in discriminability between content–context bindings in WM.     

High School Biology/Life Science Teachers’ Presentation of Genetic Counseling and Health Care Career Options in Their Classrooms

Studies show teachers play an influential role in the career decision-making process of students and early knowledge of genetic counseling (GC) increases the likelihood students will consider this career option. This quantitative study is the first to explore the presentation of GC and other health care career options by high school (HS) biology/life science (B/LS) teachers in their classrooms. Our findings indicate most B/LS teachers present GC as a career option to HS students, agree it complements classroom activities, and perceive students as interested in learning about the profession. However, teachers note many barriers to spending class time presenting GC careers. Consequently, a substantial number of teachers spent a minimal amount of time presenting health care careers in general. We discuss ways genetic counselors can enhance career resources, reduce barriers, and foster student interest in pursuing a career in GC by developing partnerships with HS B/LS teachers.
