This study takes an interest in instructions and instructed actions in the context of manual skills. The analysis focuses
on a video recorded episode where a teacher demonstrates how to crochet chain stitches, requests a group of students to reproduce
her actions, and then repeatedly corrects the attempts of one of the students. The initial request, and the students’ responses
to it, could be seen as preliminary to the series of corrective sequences that come next: the request and the following attempts
make it possible for the teacher to launch instructional sequences specifically designed and addressed to the students who
need further guidance. In the interaction between the teacher and the novice student, the reasoned character of the instructed
actions is not explained so much as installed and tuned. The materiality of the project makes it possible for the two parties
to methodically and meticulously adjust their actions in accordance with each other, and towards the gradual realization of
the aimed-for results. In connection to this, a number of issues pertaining to the reproducibility and recognizability of
manual skills are raised: how instructions-in-interaction orient towards the progression of the skill rather than the interaction
itself; how attempts by and mistakes of the instructed party provide grounds for further instruction; and, consequently, how
instructions in the form of corrections build on the instructor’s continuous assessments of the instructed actions. 相似文献

The present study examined measurement invariance of trait anger with respect to age. In addition, age-related differences in latent variables (factor variances, factor covariances, and factor means) were investigated. A sample of 1216 participants, divided into six age groups, ranging from under 30 to over 70 years, was tested using the angry temperament and angry reaction scales from the State-Trait Anger Expression Inventory (STAXI; Spielberger, 1988). Results show that strong measurement invariance held across the six age groups. For both angry temperament and angry reaction, factor variances tended to decrease into middle age and then increase again into old age. Factor correlations decreased into old age, implying a differentiation of trait anger. Finally, regarding factor means, older adults showed less anger than younger adults, suggesting higher levels of self-regulation or less exposure to anger-provoking contexts in later life. 相似文献

The present study examined the association between positive traits, pain catastrophizing, and pain perceptions. We hypothesized that pain catastrophizing would mediate the relationship between positive traits and pain. First, participants (n = 114) completed the Trait Hope Scale, the Life Orientation Test-Revised, and the Pain Catastrophizing Scale. Participants then completed the experimental pain stimulus, a cold pressor task, by submerging their hand in a circulating water bath (0 °C) for as long as tolerable. Immediately following the task, participants completed the Short-Form McGill Pain Questionnaire (MPQ-SF). Pearson correlation found associations between hope and pain catastrophizing (r = −.41, p < .01) and MPQ-SF scores (r = −.20, p < .05). Optimism was significantly associated with pain catastrophizing (r = −.44, p < .01) and MPQ-SF scores (r = −.19, p < .05). Bootstrapping, a non-parametric resampling procedure, tested for mediation and supported our hypothesis that pain catastrophizing mediated the relationship between positive traits and MPQ-SF pain report. To our knowledge, this investigation is the first to establish that the protective link between positive traits and experimental pain operates through lower pain catastrophizing. 相似文献

Studies on affordances typically focus on single objects. We investigated whether affordances are modulated by the context, defined by the relation between two objects and a hand. Participants were presented with pictures displaying two manipulable objects linked by a functional (knife-butter), a spatial (knife-coffee mug), or by no relation. They responded by pressing a key whether the objects were related or not. To determine if observing other's actions and understanding their goals would facilitate judgments, a hand was: (a) displayed near the objects; (b) grasping an object to use it; (c) grasping an object to manipulate/move it; (d) no hand was displayed. RTs were faster when objects were functionally rather than spatially related. Manipulation postures were the slowest in the functional context and functional postures were inhibited in the spatial context, probably due to mismatch between the inferred goal and the context. The absence of this interaction with foot responses instead of hands in Experiment 2 suggests that effects are due to motor simulation rather than to associations between context and hand-postures. 相似文献

Changes in natural language use as an indicator of psychotherapeutic change in personality disorders
Arntz A Hawke LD Bamelis L Spinhoven P Molendijk ML 《Behaviour research and therapy》2012,50(3):191-202
Word use has been shown to reflect various psychological processes and psychological change. This study examines the self-view in personality disorders (PDs) and its change over the course of therapy using the Linguistic Inquiry and Word Count analysis procedure. A sample of 299 participants with PDs and 108 community control participants wrote short essays about their lives. Patients repeated the assignment three times over two years and completed assessments of PD-pathology, general psychopathology, PD-beliefs, and quality of life. Results show that as hypothesized the use of words in the 1st Person Singular Pronouns, Negative Emotion, Causation, Past and Future Tense Verbs categories significantly declines over the course of treatment, while the use of Present Tense Verbs and Positive Emotion increases. These categories tend to distinguish patients from non-patients prior to treatment. We also found 12 additional word categories changing over time, including Word Count and Negations. Change in word use statistically predicts better treatment outcome on all outcome measures (p < .001). Reductions in the use of Negative Emotion Words and Negations are the strongest predictors of outcome. The non-hypothesized role of Negations was explored and seemed to reflect that PD-patients miss a lot in their lives. Reduction of what they miss seems central to recovery. This issue seems relatively neglected in theoretical and treatment models of PDs. An increased focus on what patients miss in their lives might improve our understanding and treatment of PDs. In sum, Negative Emotion and Negation word categories appear to reflect key treatment targets. 相似文献

One of the counterarguments against empirical research in psychoanalysis is that research negatively influences the treatment situation. In this paper, the impact of a neurobiological study on psychoanalytically oriented treatments is presented from three different perspectives: patients' views, a study group of participating psychoanalysts and a clinical case example. Twenty chronically depressed patients, 20 healthy controls and 16 psychoanalysts participated in the project on research. Results show a clear influence of the neurobiological study on the course of treatments. Patients consistently reported that study participation had a positive impact on their treatment experiences. However, study participation was conflictual for the psychoanalysts and forced them to carefully reflect on their unconscious and conscious involvement to establish a psychoanalytic stance independent from empirical research. 相似文献

The data obtained from one‐way independent groups designs is typically non‐normal in form and rarely equally variable across treatment populations (i.e. population variances are heterogeneous). Consequently, the classical test statistic that is used to assess statistical significance (i.e. the analysis of variance F test) typically provides invalid results (e.g. too many Type I errors, reduced power). For this reason, there has been considerable interest in finding a test statistic that is appropriate under conditions of non‐normality and variance heterogeneity. Previously recommended procedures for analysing such data include the James test, the Welch test applied either to the usual least squares estimators of central tendency and variability, or the Welch test with robust estimators (i.e. trimmed means and Winsorized variances). A new statistic proposed by Krishnamoorthy, Lu, and Mathew, intended to deal with heterogeneous variances, though not non‐normality, uses a parametric bootstrap procedure. In their investigation of the parametric bootstrap test, the authors examined its operating characteristics under limited conditions and did not compare it to the Welch test based on robust estimators. Thus, we investigated how the parametric bootstrap procedure and a modified parametric bootstrap procedure based on trimmed means perform relative to previously recommended procedures when data are non‐normal and heterogeneous. The results indicated that the tests based on trimmed means offer the best Type I error control and power when variances are unequal and at least some of the distribution shapes are non‐normal. 相似文献

The present study tested whether individual differences in autonomic nervous system functioning interact with environmental risk factors to predict adolescents' psychosocial functioning. The authors assessed skin conductance and respiratory sinus arrhythmia at rest and during laboratory stressors in 110 14-year-olds. Subsequently, adolescents and their mothers provided both questionnaire and daily diary data (over 10 days) on emotional and interpersonal functioning. The authors found stronger associations between environmental risk factors (having a single-mother household or a mother with high internalizing problems) and psychosocial outcomes (externalizing problems, daily negative affect, and daily interaction quality) among youths with specific patterns of tonic and stress-induced sympathetic and parasympathetic nervous system activity, but the pattern of moderating effects differed between boys and girls. The findings support the notion that individual differences in autonomic functioning index variation in youth's susceptibility to environmental risk factors. 相似文献
