This study reviews prior research and reports longer-term consistency of stress-related immune variables in middle-aged and older women who performed mental math and speech tasks 2 times 1 year apart. Leukocyte subsets, mitogen-induced lymphocyte proliferation, and natural killer cell activity were measured at baseline, after tasks, and after 30-min recovery. Epstein-Barr virus (EBV) antibody titers were assessed at baseline. Pearson coefficients and standardized maximum-likelihood estimates of year-to-year covariances for leukocyte subsets and EBV titers showed moderately high to high baseline and posttask consistency and lower recovery consistency; consistency for other functional immune assays and reactivity scores for all variables was moderate to low. Results support longitudinal study of psychosocial context effects on tonic immune function and posttask scores. 相似文献

Choice between two reinforcers differing in magnitude and delay was investigated in rats using an adjusting-delay discrete-trials schedule in which the two reinforcers were associated with two levers (A and B). The delay to Reinforcer A (the smaller reinforcer) was always 2 sec, whereas the delay to Reinforcer B was varied in accordance with the distribution of choices in successive blocks of trials. In Experiment 1, the mean delay to the large reinforcer during the last 5 of 60 training sessions was greater when the rats were maintained at 80% than when they were maintained at 90% of their free-feeding body weights. In Experiment 2, the delay to the larger reinforcer was greater when the two reinforcers consisted of one and two 45-mg food pellets than when they consisted of three and six pellets. The results are consistent with a model of “self-control” which posits hyperbolic relations between reinforcer value and reinforcer magnitude, and between reinforcer value and delay of reinforcement. 相似文献

Encoding seen movement of another human body requires visuo-spatial processing, and recall involves motor activity. However, encoding whole body movement patterns is affected differently by patterned and spatial secondary tasks, and this difference is reversed for encoding of spatial targets for movement (Smyth, Pearson, & Pendleton, 1988). The experiments reported here investigate the rehearsal of such movement patterns and their recall over unfilled and filled intervals. Performing, watching, or encoding a sequence of spatial positions while carrying a memory load of movement patterns did not affect recall of those movements, whereas performing, watching, or encoding a further set of patterned movements reduced the number recalled from the original set. However, memory for a series of locations in space was not affected by watching patterned movements during the interval, and only order information was affected by watching movement to a series of spatial locations during the interval. The results are discussed in terms of the independence of rehearsal mechanisms for spatial sequencing and movement patterns. 相似文献

Individual differences in a child’s sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n?=?121, ages 9–16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child’s trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments. 相似文献

Although a conventional environmentalism focuses on the health of ecological systems, Pope Francis’s 2015 environmental encyclical Laudato Sí invokes St. Francis of Assisi to emphasize God’s love for the individual organism, no matter how small. Decrying the tendency to regard other creatures as mere objects to be controlled and used, Pope Francis urges our enactment of a ‘universal communion’ governed by love. I suggest, however, that Laudato Sí’s animal ethic, as focused on ordering human and animal need, is inadequate to its overarching vision of cross-species communion. This vision requires the sort of cross-species relational bridge implicit in Maurice Merleau-Ponty’s view of agency as an irreducibly ‘animate’ expression of choice and afforded further definition in Kenneth J. Shapiro’s conception of a ‘kinesthetic empathy.’ As the phenomenological epistemology underlying both discourses makes possible a rough correspondence, I put these in conversation to demonstrate that a Merleau-Pontyan and reciprocal agency is a constitutive aspect of the fullest sort of cross-species relation, such that recognition of this agency can both deepen our understanding of ‘universal communion’ and foster engagement in its practice. 相似文献

In today’s climate, with the ever-increasing demand for competent behavior analytic services, it is necessary for behavior analysts to work across a variety of settings, including home, school, and community, overseeing instructional aide staff as the frontline providers of applied behavior analysis (ABA) services. It is common practice for ABA practitioners to provide the supervision and training to parents, caregivers, and direct-care staff, who may have limited knowledge and experience within the field of ABA. In 2013, the Behavior Analysis Certification Board (BACB®) initiated an effort to establish standards for the training of instructional aides and direct-care staff in the delivery of instructional and treatment services based on the principles of ABA. This new standard and credential is known as a Registered Behavior Technician? (RBT®). The purpose of this study was to evaluate the training process outlined by the BACB, focusing specifically on the generalizability and long-term maintenance of newly acquired skills taught through a competency-based approach, to novel opportunities for implementation. Training was conducted through two methods: in vivo training with clients versus role-play with peers. Both these types of staff training approaches are commonly used instructional practices in the field of ABA. 相似文献

Aurora Health Care in eastern Wisconsin has a clinical genetics program driven by genetic counselors in the cancer/adult and prenatal genetics settings. In 2015, the workforce shortage of genetic counselors left us with 4 open positions for genetic counselors that we were unable to fill. We explored many models of alternative service delivery, and determined virtual health (VH) via telemedicine to be the best option for our system. Historically, telemedicine technologies have been used to provide access to healthcare services to patients in remote areas. We, however, were struggling to find genetics counselors to staff both our remote clinics and urban clinics. To solve this problem, we recruited genetic counselors from across the country to work remotely from their current home or home office utilizing VH to staff our clinics. We then created clinical workflows and an implementation process of virtual health for 9 prenatal and cancer clinics across the eastern Wisconsin footprint of our healthcare system over the course of 12 months. Here we provide our experience and process in establishing a VH program in order to help other institutions that have been affected by the workforce shortage of clinical genetics professionals. 相似文献
