The role of prosody in a case of foreign accent syndrome (FAS)

Foreign accent syndrome (FAS) is a rare disorder characterized by the emergence of a perceived foreign accent following brain damage. The symptomotology, functional bases, and neural substrates of this disorder are still being elucidated. In this case study, acoustic analyses were performed on the speech of a 46‐year old monolingual female who presented with FAS of unknown aetiology. The patient had a pseudo‐accent frequently described as ‘Swedish’ or ‘Eastern European’. Stop consonant VOT, consonant burst spectra and duration, vowel durations, formant frequencies, and trajectories were analysed, along with prosodic cues for lexical stress assignment and sentence‐level intonation. Results indicated VOT values were generally preserved, while there was a strong tendency to realize the English alveolar flap as a full stop, and to produce flaps that had greater‐than‐normal closure durations. The spectral properties of the patient's vowels resembled those of normal talkers (with the possible exceptions of decreased F1 values for /i/ and slight differences in formant dynamics for /u/, /o/, /i/, and /?/). However, vowel durations were relatively long, contributing to exaggerated tense/lax contrasts. Token‐to‐token variability in vowel production was slightly higher than normal for duration, but not for formant frequency values. Lexical stress assignment was inaccurate and highly variable (with similar problems noted for non‐speech materials), and sentence level intonation showed occasional deviations from typical American English patterns. For this patient, an underlying timing/rhythm difficulty appeared responsible for the range of segmental and suprasegmental changes leading to the impression of a foreign accent.     

A study of silent disengagement and distressing emotion in psychotherapy

Abstract

Fifty-two psychotherapy sessions were coded for silences that reflect processes of client disengagement (e.g., withdrawal, resistance). The study examined the presence of these silences and clients' reports of in-session emotion and symptom change. Results indicated that disengagement predicted poorer proximal and distal outcome as measured by the Beck Depression Inventory for Primary Care (BDI-PC) and poorer proximal outcome on the Symptom Checklist-5, but it was not significantly predictive of Outcome Questionnaire-45 scores. Interitem analyses revealed that disengagement had a significant proximal effect on depressive mood and negative self-evaluative items assessed by the BDI-PC, but across time these effects were sustained for the negative self-evaluative items only.     

The Prevalence of Personality Disorders Among Those with Eating Disorders

The genuine prevalence of personality disorders among those with eating disorders is unknown. However, in this paper, we summarize the existing data, with careful acknowledgment of our approach to interpretation as well as the limitations of previous studies. Our findings indicate that obsessive-compulsive personality is the most common personality disorder in restricting-type anorexia nervosa, while borderline personality is the most common personality disorder in binge-eating/purging type anorexia nervosa. Borderline personality is the most common personality disorder in bulimia nervosa, as well. In those with binge eating disorder, obsessive-compulsive personality is the most common personality disorder although, compared with the preceding eating disorder diagnoses, there are broader clusters of personality disorders represented in this group. We discuss the implications of these findings.     

Early life and current determinants of bone in South African children of mixed ancestral origin

BACKGROUND: The influence of early life factors on the bone mineral density of children has been identified, however the contribution of these determinants may vary. AIM: The study investigated determinants of bone mineral content (BMC) in South African children of mixed ancestral origin. SUBJECTS AND METHODS: Early life data including birth weight, maternal alcohol consumption and smoking during pregnancy were collected on 9-year-old children of mixed ancestral origin (n = 64). Grip strength was measured, and physical activity, housing density and dietary data were collected. Whole body BMC (WB BMC), fat-free soft tissue and fat tissue were measured using dual energy X-ray absorptiometry. RESULTS: Maternal alcohol consumption during pregnancy was associated with WB BMC, however after adjusting for possible confounders, this was no longer significant. When combined with gender, gestational age and maternal BMC in a multiple regression, maternal alcohol consumption during pregnancy could explain 20% of the variance in the WB BMC, however when current height was included in the model, the contribution of the other factors was insignificant. There was however a significant correlation between current height and birth weight (r = 0.34; p < 0.01) and alcohol consumption during pregnancy (r = 0.34; p < 0.05). A model consisting of current factors such as age, weight, gender, grip strength and calcium intake was able to explain 81.5% of the variance. Housing density was negatively correlated with WB BMC (r =-0.11; p = 0.05). CONCLUSION: These data suggest that although early life factors may contribute indirectly to the bone mass of children of mixed ancestral origin, the contribution of current factors is greater. In addition, environmental factors such as housing density have a direct effect on bone mass, independent of body size.
