Using a judgment and component analysis of facial actions, 14 muscle-contraction headache (MCH) patients were videotaped in headache and nonheadache states. In addition, patients were also required to undergo a resting physiological assessment (frontalis electromyography, temporal blood volume pulse, and heart rate), reaction-time task, and complete self-report measures of pain state and mood. Headache and nonheadache state of MCH patients were reliably identified by 20 observers. Characteristics of facial expressions that occurred most frequently in the headache state included furrowed eyebrows, closed eyes, slow eye blinks, lip pursuing, facial grimacing, and flat facial affect. Headache state was also associated with increased latency to respond to an auditory tone and mood disturbances, but no differences in baseline physiological activity were observed. Our findings provide support for the utility and clinical relevance of judgment and component analysis of facial actions in MCH patients. 相似文献

An alleged defect in transformational treatment of syntax acquisition is the absence from child speech of certain predicted errors with ‘wh-’ constructions. In this paper, a theory of acquisition dynamics and intensive longitudinal data are brought to bear on this issue. The key observations involve an early precursor, at 24—28 months, of the relative clause. The analysis sheds light on two fundamental issues in transformational acquisition theory: The permissibility of simultaneous rule changes and whether a transformation can be acquired before the associated deep structure. The issues and analysis can be translated into non-transformational terms. 相似文献

The technique introduced here induces the organization of information in memory from systematic inspection of regularities in free recall. The form of the representation of this organization is an “ordered tree.” The technique has the advantage of being based on a theory of the way in which the data were generated and can be shown to produce a unique structure that captures all the kinds of regularities the theory of recall prescribes. Also presented is a collateral technique for measuring the amount of organization evidenced in a struture, as well as a procedure for identifying errors. The experimental work shows the technique's ability to recover the details of an organization presented to subjects and provides converging evidence for the particular structures induced from the pattern of recall pauses. In addition, the application of the technique to structures unknown a priori produced organizations that were easy to interpret and a second set of pauses that further confirmed the details of the induced structures. 相似文献

Following a more explicit explanation of the 1960 memory-drum theory and the reasons for using the simple (rather than choice) RT method in testing predictions based on it, the eight experiments utilizing large-scale precued arm movements constrained as to directional accuracy are reviewed. In all cases, increasing complexity of the movement consistently increased response latency; control RT levels agreed with well-established typical values for auditory and visual stimuli. Following practice the complexity effect leveled off, retaining a significant latency differential. Results from experiments varying duration of a held movement position (with movement minimal and complexity invariant) are not relevant to these studies. 相似文献

The effect of blood volume pulse (BVP) and frontalis muscle action potential (EMG) feedback on control of vasoconstriction of the temporal artery and frontalis muscle activity in combined migraine-muscle tension subjects was investigated in a multiple baseline design (across subjects and responses). The data indicated: (a) both subjects obtained an ability to control BVP during BVP feedback and EMG during EMG feedback; (b) there were decreases in frequency of migraine headaches during BVP feedback and decreases in muscle contraction headaches during EMG feedback. The results of this study supported the theoretical explanation of two pain mechanisms involved in combined muscle contraction-migraine headaches as well as the effectiveness of biofeedback procedures that target directly the specific pain mechanism in the elimination of the two types of head pain. 相似文献

The Coombs and Huang (1970) distributive theory of perceived risk is reinterpreted as a more robust statistical hypothesis to describe central tendencies of noisy replicates drawn from a homogeneous population. Barron's (1976) sample of 13 business faculty rank-order responses are pooled to obtain a replicated complete 3 × 3 × 3 design which is analyzed by a new stochastic conjoint measurement (SCJM) approach to axiomatic data analysis. SCJM implements statistical analogues of the deterministic Krantz and Tversky (1971) diagnostics for error-free data. SCJM diagnosis based on a series of one-sided nonparametric two-cell comparisons at the α = 0.04 level supports the hypothesis of interaction between the expected-value and number-of-plays attributes of gambles yet contradicts Barron's odd-even effects hypothesis. SCJM diagnosis with two-cell α < 0.04 supports an additive statistical model. 相似文献

Temporal darkness enhancement refers to the finding that decremental flashes of 50–140 msec appear darker than longer flash decrements. The present experiment determined the effects of temporal waveform upon darkness enhancement by obtaining darkness judgments for flashes that had abrupt onset/abrupt offset, abrupt onset/gradual offset, gradual onset/abrupt offset, and gradual onset/gradual offset. Temporal darkness enhancement was found only for flashes that had abrupt onsets regardless of offset waveform. These results are discussed in terms of the role of transients in the coding of perceived darkness. 相似文献
