This article explores the challenges presented by the mandate for evidence‐based practice for family therapists who identify with the philosophical stance of social construction. The history of psychotherapy outcome research is reviewed, as are current findings that provide empirical evidence for an engaged, dialogic practice. The authors suggest that the binary between empiricism and social construction may be unhinged by understanding empiricism as a particular discursive frame (i.e., a particular way of talking, acting, and being in the world), one of many available as a way of understanding and talking about our work. Through a case vignette, the authors introduce the evidence‐based practice of Feedback Informed Treatment as an elaboration of social construction, and as an example of bridging the gap between the discursive frames of empiricism and social construction. 相似文献

Action planning, but not action execution, in speeded tasks is typically faster when responses and their effects are compatible
than when they are incompatible. We tested whether response-effect compatibility (REC) affects the execution of music-like
sequential actions that require temporal regularity rather than rapidity. Musicians responded to metronomic visual stimuli
by producing sequences of three taps at a specific tempo on three vertically aligned keys. Each tap triggered a tone. Key-to-tone
mapping was either compatible or incompatible in terms of spatial height and pitch height. The results indicated that tap
timing was more accurate with compatible than with incompatible mappings, both for taps produced before (Tap 1) and after
(Taps 2 and 3) the onset of auditory feedback. Thus, the observed influence of REC on action execution was not due exclusively
to actual auditory feedback. The anticipation of distal action effects may be involved in planning the dynamics of temporally
precise movements. 相似文献

The goal of the present study was to evaluate the contributions of various brain structures anatomically and functionally linked to the hippocampus and amygdala in a fear-based context discrimination task. The brain areas of interest included the fornix, medial prefrontal cortex, mediodorsal (MD) thalamic nucleus, and nucleus accumbens. Damage to the MD thalamic nucleus and medial prefrontal cortex produced the largest impairment in context-specific fear responses. Damage to the fornix impaired some fear responses (freezing, ultrasonic vocalizations, defecation, and approach/avoidance) while leaving conditioned fear expression of heart rate and urination unaltered. Damage to the nucleus accumbens was also coupled with deficits in the discriminative expression of some (heart rate, urination, and ultrasonic vocalizations) but sparing of context-appropriate freezing, defecation, and approach/avoidance behaviors. 相似文献

Studies of hormone therapy (HT) and cognition have yielded conflicting results. The aim of this observational study was to examine the effect of estradiol, via serum verified HT (estradiol, estriol, progesterone) and endogenous estradiol, on 108 healthy postmenopausal women's cognitive performance. The results demonstrated that the 43 HT-users performed at a significantly higher level than non-users on episodic memory tasks and on a verbal fluency task, whereas HT-users and non-users did not differ on tasks assessing semantic memory and spatial visualization. In addition, there was a positive relationship between serum estradiol level and episodic memory performance, indicating that postmenopausal HT is associated with enhanced episodic memory and verbal fluency, independent of age and education. These observational results suggest that HT use may be sufficient to exert small, yet positive effects on female sensitive cognitive tasks. Hormone therapy compliance and formulation is discussed as confounding factors in previous research. 相似文献

This paper links experimental psycholinguistics and theoretical syntax in the study of subject-verb agreement. Three experiments of elicited spoken production making use of specific characteristics of Italian and French are presented. They manipulate and examine its impact on the occurrence of 'attraction' errors (i.e. incorrect agreement with a word that is not the subject of the sentence). Experiment 1 (in Italian) shows that subject modifiers do not trigger attraction errors in free inverted VS (Verb Subject) structures, although attraction was found in VS interrogatives in English (Vigliocco, G., & Nicol, J. (1998). Separating hierarchical relations and word order in language production. Is proximity concord syntactic or linear? Cognition, 13-29) In Experiment 2 (in French), we report stronger attraction with preverbal clitic object pronouns than with subject modifiers. Experiment 3 (in French) shows that displaced direct objects in the cleft construction trigger attraction effects, in spite of the fact that the object does not intervene between the subject and the verb in the surface word order (OSV). Moreover, attraction is stronger in structures with subject-verb inversion (...). These observations are shown to be naturally interpretable through the tools of formal syntax, as elaborated within the Principles and Parameters/Minimalist tradition. Three important constructs are discussed: (1) the hierarchical representation of the sentence during syntactic construction, and the role of intermediate positions by which words transit when they move; (2) the role of specific hierarchical (c-command) but also linear (precedence) relations; and (3) the possibility that agreement involves two functionally distinct components. A gradient of computational complexity in agreement is presented which relates empirical evidence to these theoretical constructs. 相似文献

In a sample of 143 adults from a population of households in Idaho, significant differences in patterns of alcohol use and attitudes about underage drinking were related to parental status. Nonparents reported drinking alcohol more frequently than parents. Parents were significantly more likely than nonparents to report that it is never acceptable for minors to drink alcohol, that minors should not be allowed to drink alcohol at parties with no parents present, and that "sting" operations by police are warranted. Surprisingly, nonparents were significantly more likely than parents to report stores and bars are not careful enough about selling alcohol to minors. 相似文献

520 college students from a public university in the southwest were questioned to examine correlations between having a tattoo and the presence of tattoos among their family and friends. Tattoos among both friends and family were positively correlated with respondents' having a tattoo. The magnitude of friends' influence was about double the influence of family. 相似文献

Dissociation of event-related potentials indexing arousal and semantic cohesion during emotional word encoding 总被引:3,自引:0,他引:3
Event-related potential (ERP) studies have shown that emotional stimuli elicit greater amplitude late positive-polarity potentials (LPPs) than neutral stimuli. This effect has been attributed to arousal, but emotional stimuli are also more semantically coherent than uncategorized neutral stimuli. ERPs were recorded during encoding of positive, negative, uncategorized neutral, and categorized neutral words. Differences in LPP amplitude elicited by emotional versus uncategorized neutral stimuli were evident from 450 to 1000 ms. From 450 to 700 ms, LPP effects at midline and right hemisphere frontal electrodes indexed arousal, whereas LPP effects at left hemisphere centro-parietal electrodes indexed semantic cohesion. This dissociation helps specify the processes underlying emotional stimulus encoding, and suggests the need to control for semantic cohesion in emotional information processing studies. 相似文献

Age differences in fluid intelligence: contributions of general slowing and frontal decline 总被引:2,自引:0,他引:2
The current study examined the contributions of general slowing and frontal decline to age differences in fluid intelligence. Participants aged 20-89 years completed Block Design, Matrix Reasoning, simple reaction time, choice reaction time, Wisconsin Card Sorting, and Tower of London tasks. Age-related declines in fluid intelligence, speed of processing, and frontal function were observed. Hierarchical regression analyses showed that the processing speed and frontal function measures accounted for significant variance in fluid intelligence performance, but there was also a residual effect of age after controlling for each variable individually as well as both variables. An additional analysis showed that the variance in fluid intelligence that was attributable to processing speed was not fully shared with the variance attributable to frontal function. These findings suggest that the age-related decline in fluid intelligence is due to general slowing and frontal decline, as well as other unidentified factors. 相似文献
