This paper describes a preparation for recording action potentials from the central nervous system of an intact self-respiring fish. The cervical spinal cord of the anesthetized fish was lesioned to minimize body movements, and the brain was exposed by cutting a hole in the dorsal skull. A clamp was attached to the rostral edge of this hole to eliminate motion of the skull. The fish in this preparation can control its own respiration and thus maintain an essentially normal respiratory state. This is a significant improvement over previous preparations, as respiratory state has been shown to be an important determinant of central nervous system function.  相似文献

Twelve cases with agoraphobic and other phobic symptoms are presented. Their family backgrounds and marital relationships are delineated. A consistent pattern, the phobic-counterphobic system, emerges. This contains five elements. (1) Anxious ambivalent attachment, which characterizes the previous childhood relationships of both partners in the marriage. The future patient has responded to this with a tendency to clinging behaviour, her spouse with a propensity to detachment. (2) A marriage in which, initially, each, through the other, escapes from their childhood difficulties. (3) A precipitating change with challenges the couple's illusionary unity. (4) A period of escalation and failure of reassurance by the husband. (5) The illness, which stabilizes the system and leads to a 'compulsory marriage'. Therapeutic approaches for each of these elements are described.  相似文献

When people argue with others in conversation, they make a variety of conversational moves: They make claims, ask for justification of others' claims, attack claims, and attack claims' justifications. The arrangement of these moves gives argumentation its characteristic shape. This article illustrates a proposed format for conversations of this type, and it reviews some findings about the way people understand and evaluate these conversations. The findings suggest that judgments of the arguers' burden depend not only on the content of their claims, but also on the conversation's structure. In addition, judgments of the strength of a justification—an arguer's evidence or explanation—are a function of the argument's setting.  相似文献

PSYCHLOPS (Psychological Outcome Profiles) is a recently developed, client‐generated, psychometric instrument that can be used as an outcome measure. Based on a similar instrument developed primarily for use in physical illnesses (MYMOP — ‘Measure Your Medical Outcome Profile’), it seeks the client's perspective on their psychological distress. It asks them to describe and then score the problem that troubles them the most at the start of counselling. We describe the development of PSYCHLOPS, including the involvement of the Plain English Campaign and two national mental health organisations: the mental health charity and support group, Depression Alliance (DA) and Primary Care Mental Health Education (PRIMHE). We review the literature and suggest that PSYCHLOPS, by focusing on the problems of greatest priority to the client, might prove a sensitive measure of improvement after counselling.  相似文献

Rather than treating paired associate and serial learning as involving the acquisition of distinct types of information [e.g. Murdock (1974). Human memory: Theory and data. New York: Wiley] I propose an Isolation Principle which treats the two as ends of a continuum. According to this principle, consecutive pairs of items are relatively isolated from other studied items in paired associates learning, but not isolated in serial list learning. The consequence is that variability that dominates forward and backward probed recall is highly correlated in pairs but less so, due to differential interference, in lists. This can explain an important dissociation: whereas forward and backward probes of pairs are nearly perfectly correlated, the correlation is only moderate for serial lists. I demonstrate this in a chaining model by varying item-to-item associative strengths and in a positional coding model by varying the similarity structure of item positions. This enables a range of models to account for data on pairs and lists, as well as potential intermediate or hybrid paradigms, within a single theoretical framework.  相似文献

The authors tested the hypothesis that there is a correlation between hemispheric cognitive style and ear temperature. A sample of 100 participants completed a measure of hemispheric cognitive style, the Hemispheric Consensus Prediction Profile. Ear temperatures were taken in 2 sessions, 2 times for each ear at each session. Average left ear temperature was subtracted from average right ear temperature as an index of dominant temperature. Only 56 of the participants showed a stable dominant ear temperature. For these 56 participants, there was a statistically significant positive correlation between scores on the Hemispheric Consensus Prediction Profile and tympanic member temperature (Spearman's ρ =.29, 95% CI [.04,.51]). Individuals with a left hemispheric cognitive style tended to have a warmer left tympanic membrane temperature while those with a right hemispheric cognitive style tended to have a warmer right tympanic membrane temperature. Tympanic membrane temperatures are easily obtained using inexpensive and noninvasive technology. The relationship suggested by these findings may open new opportunities for the study of cerebral asymmetry.  相似文献

The effects of letter substitutions have been linked to their position within a word (letter position effects). The current study expanded upon previous research by examining letter-position effects for letter substitutions using forward- and reverse-spelled word primes. Often substituting a letter on one side of a word will have a stronger impact on performance than substituting a letter on the other side of a word. In three experiments it was revealed that the letter-position effects of substitutions changed places when words were spelled backwards. This occurred when both the target and prime were spelled backwards. This was evidence of a congruency effect of letter-position priming. The ramifications of these results for word recognition and transfer are discussed. However, the need for future research should focus on the possibility of an inversion process/mechanism.  相似文献

Many scholars have written about the role of spirituality in health care. One mechanism for incorporating spirituality into the care of patients is to integrate clinically trained chaplains into hospital care teams. We examined in a mixed-methods fashion, the effects of this type of integrated care team within a teaching hospital setting. The quality and impact of chaplain involvement were studied from patient and physician-in-training perspectives, using data from more than 200 patients and physicians in training. Findings clearly show that clinically trained chaplains can contribute meaningful expertise and real value to the quality and comprehensiveness of patient and physician experiences.  相似文献

Time-out (TO) is one of the most common and effective disciplinary tactics used to address problem behavior; however, parents rate TO as one of the least useful behavior modification techniques. This may be due to a discrepancy between empirically supported TO procedures and how mothers are actually conducting TO. Fifty-five mothers were asked to define TO, provide information on how they conduct TO, and identify errors in TO procedures. Results indicate that maternal knowledge and implementation of TO differs considerably from the empirical ideal, potentially impacting the utility and frequency of TO usage in the home to address child problem behaviors.  相似文献

This study evaluated whether a participatory action research intervention with nursing staff on acute care older people National Health Service wards in the United Kingdom was effective for increasing work engagement. Mediation analyses between job resources (social support, influence in decision-making), job demands, work-related needs (autonomy, competence, relatedness), and work engagement explored the presumed psychological mechanisms underlying the intervention. A non-randomized, matched control group, pretest, post-test design involved three intervention and five control wards. A significant decrease in relatedness, and a borderline significant decrease in competence, was observed in the intervention group compared to the control group, with no effect on work engagement (N = 45). Work-related needs mediated between resources and work engagement, supporting the job demands-resources model and self-determination theory as an underlying explanatory theory. Intervention implementation was difficult, highlighting the need for participant and organizational readiness for change, and strong management support. This is the first known study to apply participatory techniques to increase work engagement in nursing staff and explore the underlying explanatory psychological mechanisms, offering a novel means of taking work engagement research forward. Crucially, it highlights the challenges involved in intervention research and the importance of including evaluations of intervention implementation alongside statistical evaluations to avoid erroneous conclusions.  相似文献
