When genetics is considered in diathesis-stress models of psychopathology, it is often assumed that heredity provides the diathesis and environmental factors are responsible for the stressor. We discuss two quantitative genetic models relevant to the diathesis-stress construct. One model focuses on genotype-environment interaction, which is the usual way in which genetic influence is represented in diathesis-stress models. A second model—genotype-environment correlation—provides an alternative that represents both genetic and environmental influences relevant to the development of psychopathology. Implications of these models for clinical research are discussed. 相似文献

Accuracy and laterality of ear preference in repeating 2, 3 and 4 word pairs (WP) of dichotic stimuli in English and French were determined in 80 right-handed subjects (anglophone/francophone, male/female), who were tested in both their native language (L1) and nonnative language (L2). Relative performance accuracy decreased as a function of word pairs per trial (from 2 to 4) as well as language (from L1 to L2). Right-lateral preference in turn increased as a function of WP (from 2 to 4) as well as language (L1 to L2). Right-ear advantage (REA) in L2 decreased as a function of language proficiency (low to high). REA was observed in over 90% of subjects. A rationale for greater lateralization of L2 performance is offered. 相似文献

The reading performance of a Japanese Broca-type aphasic patient on a single-word reading test was investigated. The result indicated that the subject fits the symptom complex of deep dyslexia in more than one aspect. Unique characteristics of this subject included (1) the isolated subcortical site of the lesion, which apparently produced deep dyslexia, and (2) double dissociations between kanji and kana processing and between oral reading and reading comprehension. The performance of this subject was compared with that of another Japanese deep dyslexic subject in S. Sasanuma (1980, In M. Coltheart, K. Patterson, & J. C. Marshall (Eds.), Deep dyslexia, London: Routledge & Kegan Paul). A theoretical implication was attempted based on a dual coding process scheme by S. Sasanuma and O. Fujimura (1978, Cortex, 7, 1-18). 相似文献

How concerned are primary-school-aged stuttering children about their communication problem? What are the clinical implications of this concern?Fifteen years ago, Silverman (1970) suggested that primary-school-aged children who stuttered were not concerned about their disfluencies. A clinical implication of that report was that the interpreted lack of concern might negatively affect the children's motivation and desire for change in therapy. Scant research exists to support or refute this implication. While research is available on reactions to stuttering, pretherapeutic attitudes—especially those of children—have not been systematically reported. Guitar (1976) measured the pre-treatment attitudes of 38 adult stutterers and reported that, “those stutterers with more negative attitudes measured just prior to treatment, were most likely to have high levels of stuttering a year later, even though all subjects left therapy entirely fluent.” In related areas, research by Kolb, Winter, and Berlen (1968), McFall (1970), and McFall and Hammen (1971) has indicated that clients who are more motivated do better in behavior modification programs.Whether or not these findings may be generalized to children, in the midst of a developmental process, is purely speculative. 相似文献

The purpose of this study was to determine the extent to which stutters manipulate vowel duration to achieve fluency after participating in Precision Fluency Shaping. Nine stutterers who read an all-voiced sentence fluently before and after therapy were selected for study. Wide-band spectrograms were made of the initial phrase of the sentences, and vowel durations were computed. Results indicated that extended vowel durations were characteristic of the fluency of stutterers posttherapy. The subject that had the highest rate of disfluency after therapy also had the shortest vowel durations. Clinical implications concerning the importance of speech rate during carryover practice are made. 相似文献

In an investigation of the effects of simulated stuttering on listener recall, a presentation was varied on two factors: degree of stuttering (mild or severe) and information value of stuttered words (low or high). A control presentation featuring non-stuttered speech also was prepared. Five groups of 16 subjects were randomly assigned to, and participated in, one of the five listening conditions. Then they completed a 20-item recall test. A one-way analysis of variance revealed sognificant differences among the five conditions. Two-way analysis of variance disclosed no main effects. However, a significant interaction showed that recall was lowest in the severe stuttering-high information condition. The results are discussed in terms of attention to critical information. 相似文献

Message therapy is a clinical procedure designed to be used as a carry-over technique with school-age stutterers or as a sole technique with the preschooler. The focus of therapy is on a unit of communication rather than on the moment or place of stuttering. One of the basic assumptions of the procedure is that the child is beginning to monitor how he/she is speaking rather than what is being communicated (i.e., the “message”)—each task requiring a different cognitive process. The emphasis of the therapy is to redirect the child's attention to “what he/she is saying.” The clinical procedures are discussed as they relate to the specific population. 相似文献
