Implicit attitudes are mental states that appear sometimes to cause agents to act in ways that conflict with their considered beliefs. Implicit attitudes are usually held to be mere associations between representations. Recently, however, some philosophers have suggested that they are, or are very like, ordinary beliefs: they are apt to feature in properly inferential processing. This claim is important, in part because there is good reason to think that the vocabulary in which we make moral assessments of ourselves and of others is keyed to folk psychological concepts, like ‘belief’, and not to concepts that feature only in scientific psychology: if implicit attitudes are beliefs there is a prima facie case for thinking that they can serve as the basis for particular kinds of moral assessment. In this paper I argue that while implicit attitudes have propositional structure, their sensitivity and responsiveness to other mental representations is too patchy and fragmented for them to properly be considered beliefs. Instead, they are a sui generis kind of mental state, a state I dub patchy endorsements.  相似文献

The Spanish version of the five-item Francis scale of attitude toward Christianity is a refinement of the short version of the Francis scale of attitude toward Christianity. The scale is a good measurement for intrinsic religiosity. It has been applied previously among Colombian adolescent students. The internal consistency and construct and nomological validity were tested among a sample of 1349 Colombian college students from Santa Marta, Colombia. Participants were aged between 18- and 30-years-old; 51% were men; and 68% were social science students. Exploratory analysis factor, Cronbach alpha and omega McDonald were computed. The scale showed high internal consistency (both alpha and omega = .96) and excellent construct and nomological validity (one factor which explained for 88% of variance; women scored higher than men; and Protestants scored higher than Catholics and students with other religion filiations). The five-item Francis scale can be used further researches in Hispano-America among college students.  相似文献

The heterozygote reeler mouse (HRM) shows many neuroanatomical and biochemical features that are also present in some human cognitive disorders, such as schizophrenia. In the present study, hippocampal dependent plasticity and cognitive function of the HRM were characterized in detail in an attempt to reveal phenotypic functional differences that result from Reelin haploinsufficiency. The HRM and wild type mice show similar levels of overall activity, coordination, thermal nociception, startle responses, and anxiety-like behavior. In addition, both genotypes show similar shock threshold, identical cued freezing behavior and comparable spatial learning in Morris water maze tasks. However, a significant reduction in contextual fear conditioned learning was observed in the HRM. Electrophysiological studies in hippocampal CA1 synapses revealed a plethora of differences between genotypes. The HRM exhibits reduced field excitatory postsynaptic potentials in responses to similar synaptic inputs, lowered paired pulse facilitation ratio and impaired long-term depression and tetanus-induced long-term potentiation (LTP). Also, deficits were detected in LTP elicited by theta burst stimulation or by a whole cell pairing protocol. These physiologic differences could not be accounted for by changes in the overall amount of glutamate receptor subunits. In addition, it was determined that network-driven excitatory and inhibitory activities recorded in CA1 pyramidal neurons showed that the HRM had comparable amplitude and frequency of spontaneous excitatory postsynaptic currents, but a marked reduction in spontaneous inhibitory postsynaptic currents. Thus, the HRM exhibits a specific hippocampal-dependent learning deficit accompanied with a pronounced impairment of hippocampal plasticity and functional inhibitory innervation.  相似文献

Interest in the exploration of spirituality in medical practice has been growing recently due to some studies suggesting its role in the improvement of patient well-being and quality of life. This project examined the feasibility of providing spiritual coaching with patients in an outpatient Radiation Oncology clinic setting. The purpose of spiritual coaching was to provide patients with opportunities to explore their current spiritual lives, increase their involvement in spiritually enhancing activities, and expand their spiritual opportunities. Quality-of-life measurements focused on feelings of hopefulness and distress were used in patients undergoing radiation treatment for cancer. This study suggests that there is a potential benefit for spiritual coaching in the care of cancer patients, and future studies will be done to further el ucidate the ationship of spirituality and quality of life in this population.  相似文献

The debate in family therapy between structural and narrative therapists often seems irreconcilable. Drawing from work in theoretical sociology that identifies the basic structure of existing social theory, a metaperspective is introduced to clarify a discussion between leading figures in the debate. Disparate views of family interactions are examined in terms of more fundamental disagreements about the center of attention in therapy. Narrative and structural modes of presentation are examined as separate traditions that could not be further apart conceptually. Efforts to identify common ground are discussed in terms of more significant differences that are minimized by drawing out similarities. This analysis provides a framework for standing outside entrenched arguments to see more clearly the unique contributions of each approach.  相似文献

10 male collegiate runners (M age = 21.4, SD = 1.5 yr.) ran on a treadmill with no body-weight support (BWS), 20% BWS, and 40% BWS conditions. In addition, they wore three different commercially available harnesses at the 20% and 40% BWS conditions. The aim was to run on the treadmill at a fast speed while maintaining an adequate step length. The purpose was to investigate how each harness changed running gait, and the differences in running gait between the harnesses with various body-weight support. Analysis of variance indicated significant restriction of upper body torso rotation between the harnesses at the 40% BWS conditions. Body-weight support resulted in a longer stride, decreased cadence, less vertical displacement of the center of mass, and diminished hip and ankle joint excursions. These changes indicated that increased body-weight support results in longer steps with the foot contacting the belt for a shorter period of time with less leg angular changes throughout the running cycling.  相似文献

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources "wasted" on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.  相似文献

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known physical theory T. Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge. The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity.  相似文献

Seventy-four pre-service teachers in an urban graduate school of education were administered VIEW: An Assessment of Problem Solving Style and a questionnaire in which they were asked to rate the importance of numerous principles of learning, teaching, and problem solving. Judges had previously classified these principles according to the six different VIEW problem solving styles (Explorer, Developer, External, Internal, Person-oriented, Task-oriented). Participants categorized by a particular style rated more highly those principles that matched their style. Implications for instruction and the development of problem solving skills are discussed.  相似文献
