This event-related potential (ERP) study examined the impact of phonological variation resulting from a vowel merger on phoneme perception. The perception of the /e/-/ε/ contrast which does not exist in Southern French-speaking regions, and which is in the process of merging in Northern French-speaking regions, was compared to the /ø/-/y/ contrast, which is stable in all French-speaking regions. French-speaking participants from Switzerland for whom the /e/-/ε/ contrast is preserved, but who are exposed to different regional variants, had to perform a same-different task. They first heard four phonemically identical but acoustically different syllables (e.g., /be/-/be/-/be/-/be/), and then heard the test syllable which was either phonemically identical to (/be/) or phonemically different from (/bε/) the preceding context stimuli. The results showed that the unstable /e/-/ε/ contrast only induced a mismatch negativity (MMN), whereas the /ø/-/y/ contrast elicited both a MMN and electrophysiological differences on the P200. These findings were in line with the behavioral results in which responses were slower and more error-prone in the /e/-/ε/ deviant condition than in the /ø/-/y/ deviant condition. Together these findings suggest that the regional variability in the speech input to which listeners are exposed affects the perception of speech sounds in their own accent. 相似文献

Time is essential to speech. The duration of speech segments plays a critical role in the perceptual identification of these segments, and therefore in that of spoken words. Here, using a French word identification task, we show that vowels are perceived as shorter when attention is divided between two tasks, as compared to a single task control condition. This temporal underestimation pattern is consistent with attentional models of timing and hence demonstrates that vowel duration is explicitly estimated using a central general-purpose timer. 相似文献

Children’s early word production is influenced by the statistical frequency of speech sounds and combinations. Three experiments asked whether this production effect can be explained by a perceptual learning mechanism that is sensitive to word-token frequency and/or variability. Four-year-olds were exposed to nonwords that were either frequent (presented 10 times) or infrequent (presented once). When the frequent nonwords were spoken by the same talker, children showed no significant effect of perceptual frequency on production. When the frequent nonwords were spoken by different talkers, children produced them with fewer errors and shorter latencies. The results implicate token variability in perceptual learning. 相似文献

Rhythm is the speech property related to the temporal organization of sounds. Considerable evidence is now available for suggesting that dementia of Alzheimer’s type is associated with impairments in speech rhythm. The aim of this study is to assess the use of an automatic computerized system for measuring speech rhythm characteristics in an oral reading task performed by 45 patients with Alzheimer’s disease (AD) compared with those same characteristics among 82 healthy older adults without a diagnosis of dementia, and matched by age, sex and cultural background. Ranges of rhythmic-metric and clinical measurements were applied. The results show rhythmic differences between the groups, with higher variability of syllabic intervals in AD patients. Signal processing algorithms applied to oral reading recordings prove to be capable of differentiating between AD patients and older adults without dementia with an accuracy of 87% (specificity 81.7%, sensitivity 82.2%), based on the standard deviation of the duration of syllabic intervals. Experimental results show that the syllabic variability measurements extracted from the speech signal can be used to distinguish between older adults without a diagnosis of dementia and those with AD, and may be useful as a tool for the objective study and quantification of speech deficits in AD. 相似文献

Miriam Greenspan 《Women & Therapy》2017,40(3-4):334-345
ABSTRACTIn this essay, Miriam Greenspan reviews her life’s work as an early pioneer of Feminist Therapy, the influence of her birth in a displaced person’s camp to parents who were Holocaust survivors, and her development as a feminist, social activist, and psychotherapist. She discusses her most influential works, including A New Approach to Women & Therapy (1983, 1993) and Healing Through the Dark Emotions: The Wisdom of Grief, Fear, and Despair (2003). She concludes with a look back at her own spiritual evolution, her assessment of the ultimate contribution of Feminist Therapy to society, the need for a wide model of therapy that incorporates the political and spiritual dimensions of experience, and the challenges that psychology and psychotherapy face in an age of global threat. 相似文献

采用图-词干扰范式,要求被试口语产生包含三个名词的句子,同时听觉呈现干扰刺激并操纵其与各个名词的语音相关性,通过与无关刺激相比,与各个名词语音相关的干扰刺激产生的语音效应,探讨句子产生中音韵编码的计划广度,同时检验音韵编码的层级激活假设。结果发现,只有第一个名词上出现了语音促进效应,第二和第三个名词上既无语音促进,也无语音干扰。该结果与层级激活假设相悖,表明句子产生中音韵编码的计划广度为第一个韵律词。 相似文献

This randomized controlled trial (RCT) aimed to pilot the newly developed manualized and monitored systemic therapy (ST) for social anxiety disorder (SAD), as compared to manualized and monitored cognitive behavioral therapy (CBT). We conducted a prospective multicenter, assessor-blind pilot RCT on 38 outpatients (ICD F40.1; Structured Clinical Interview for DSM (SCID); Liebowitz Social Anxiety Scale, LSAS-SR >30). The primary outcome was level of social anxiety (LSAS-SR) at the end of treatment. A total of 252 persons were screened, and 38 patients were randomized and started therapy (CBT: 20 patients; ST: 18 patients; age: M = 36 years, SD = 14). Within-group, simple-effect intent-to-treat analyses (ITT) showed significant reduction in LSAS-SR (CBT:d = 1.04; ST:d = 1.67), while ITT mixed-design ANOVA demonstrated the advantage of ST (d = 0.81). Per-protocol analyses supported these results. Remission based on reliable change indices also demonstrated significant difference (LSAS-SR: 15% in CBT; 39% in ST;h: 0.550), supported by blind diagnosticians’ ratings of those who completed therapy (SCID; 45% in CBT, 78% in ST,p = .083). No adverse events were reported. CBT and ST both reduced social anxiety, supporting patient improvement with the newly developed ST for SAD; this has yet to be verified in a subsequent confirmatory RCT. 相似文献

Impairments in family functioning are associated with more severe depressive and manic symptoms, earlier recurrences, and more suicidal behaviors in early-onset bipolar disorder. This study examined whether family-focused treatment for adolescents (FFT-A) with BD I or II disorder led to greater increases in family cohesion and adaptability and decreases in conflict over 2 years compared to a briefer psychoeducational treatment (enhanced care, EC). Participants were 144 adolescents (mean age: 15.6 ± 1.4 years) with BD I or II with a mood episode in the previous 3 months. Adolescents and parents were randomized to either FFT-A (21 sessions) or EC (three sessions). Patients received guideline-based pharmacotherapy throughout the 2-year study. Trajectories of adolescent- and parent-rated family cohesion, adaptability, and conflict were analyzed over 2 years. FFT-A had greater effects on adolescent-rated family cohesion compared to EC over 2 years. Participants in FFT-A and EC reported similar improvements in family conflict across the 2 years. In the FFT-A group, low-conflict families had greater adolescent-rated family cohesion throughout the study compared to high-conflict families. High-conflict families in both treatment groups tended to show larger reductions in conflict over 2 years than low-conflict families. Family psychoeducation and skills training may improve family cohesion in the early stages of BD. Measuring levels of family conflict at the start of treatment may inform treatment responsiveness among those receiving FFT-A. 相似文献

Prior research indicates that couples who cope with chronic illness from a relational “we” orientation experience more positive outcomes than couples that cope individually; however, little prior research identifies clinical processes that promote reciprocity or how societal gender processes are involved. This grounded theory analysis of 25 videotaped therapy sessions with six heterosexual couples coping with chronic liver disease (LD) used a feminist-informed relational lens to focus on the clinical processes involved in shifting from an individual to a relational orientation. Findings identified three contextual barriers to attaining a “we orientation”: (a) autonomy discourse, (b) illness-related power, and (c) gendered power. Analysis detailed therapist actions that decreased the impact of barriers to reciprocity and fostered relational coping. Clinical implications attend to complex intersections among gender, caregiving, and contextual barriers to reciprocity. 相似文献
