认知失败的研究综述：概念、测量及相关研究

自Broadbent等首次提出认知失败的概念以来,认知失败引起了研究者的广泛注意。认知失败是个体基于认知上的因素,使他们在完成那些平日中能够胜任的简单任务时出现错误。文章从认知失败的因素结构、认知失败与选择注意、持续注意等认知因素的关系,以及与人格特征等关系几个角度回顾了已有的研究,并提出未来的研究方向。     

Life history, sin, and disease.

On the basis of experiences in pastoral hospital care, the relationship between disease, sin, and guilt in the life of patients is explored. Against the disregard of this subject in medicine, and even in most of pastoral care, it is argued that patients' interest requires that their hidden or manifest questions be addressed, rather than their being exposed to efforts at "helping" through mere attempts at "debt clearance." Only by openly confronting sin and guilt can the patient be taken seriously in his role as subject of his disease. Theological and anthropological background considerations revealing the essence of sin as a disruption or even destruction of the Divine gift of life in its realization through a lived relationship to God and other humans are offered as evidence for this claim.     

Paradoxical drug response and the placebo effect: a discussion of Grunbaum's definitional scheme

Grunbaum claims that the remedial failure of atreatment's characteristic factors is thegeneric, objective property of a placebo. Hestipulates that a treatment is placebic if thisremedial failure exacerbates the targetdisorder. This stipulation can subsume asplacebic effects that might be solelypharmacological, e.g., paradoxical reactions tocertain psychiatric drugs. If that exacerbationcan be explained pharmacologically, then wemight question whether Grunbaum's definitionalscheme captures the core identity of what weusually intend by the placebo concept. Ipropose that this core identity is bestcaptured by a symbolic meaning hypothesis inwhich psychological factors exert thedeterminative influence.     

Heart Rate Variability and Sustained Attention in ADHD Children

The major goal of the current study was to investigate the association between continuous performance tests (CPTs) and the heart rate variability (HRV) of attention deficit hyperactivity disorder (ADHD) children. The HRV, specifically the 0.10-Hz component, may be considered to be a psychophysiological index of effort allocation (motivation): The less effort the subject allocates, the greater the 0.10-Hz component. Results indicated that, compared to controls, ADHD subjects had a greater 0.10-Hz component, which was associated with poor test performance over time. Thus, using a psychophysiological measure, we were able to confirm the clinical concept of ADHD from a motivational perspective.     

Positive Affect: A Neglected Group Treatment Outcome Measure in Assessing Efficacy of Psychosocial Group Interventions in Individuals with Heart Failure

Positive affect has been neglected in evaluation of group treatment efficacy. This pilot study for individuals with heart failure illustrates the contribution of positive affect to change processes. Assessment of positive affect pre- and post-group intervention can yield a better understanding of individuals' adjustment to heart failure, and provide additional information for selection of specific treatments for each individual. In an era characterized by standardized measures of outcome, inclusion of positive affect provides additional opportunity to document contributions in improving health related quality of life (psychosocial and physical functioning) of clients with heart failure.     

Recognition failure and integration

If a recognition test is followed by a cued recall test then the probability of recognition given recall generally follows the Tulving-Wiseman function. Despite this regularity two types of exceptions have been discovered. Both poor integration and cue overlap causes an observed value of recognition given recall that is higher than predicted. The present study explores the first type of exception by proposing and testing an analytical tool, which emanates from confidence ratings given to recall responses, for relating poor integration directly to variations in the degree of deviation from the function. It is demonstrated that very poor integration produces a deviation above the function, whereas a very good integration produces a deviation below the function. The effect of integration (and cue overlap) is explained by means of a conceptualization cue dependency. Support is also given to the notion that an enhanced variability of goodness of encoding contributes to an enhanced dependence between recall and recognition.     

Cognitive deficits related to major organ failure: The potential role of neuropsychological testing

Until recently, little attention has been paid to the possibility of cognitive deficits in patients with disease or failure of major organs such as the liver, kidney, or heart. However, there is a growing awareness that major organ failure often has neuropsychological sequelae. These sequelae may at times be quite subtle and not detectable under gross. examination. Nevertheless, even subtle deficits may have a major impact on adherence to medical regimens, psychosocial adjustment, and quality of life of patients. Neuropsychological assessment has a potentially valuable role to play both in research and in clinical work. It can be useful in adding to our knowledge of the cognitive effects of various types, severity and duration of major organ disease, as well as sequelae associated with treatment. It also is a potentially valuable clinical tool for identifying cognitive deficits that will affect the quality of life and probability of survival for organ failure patients.
