We examine the mechanisms that support interaction between lexical, phonological and phonetic processes during language production. Studies of the phonetics of speech errors have provided evidence that partially activated lexical and phonological representations influence phonetic processing. We examine how these interactive effects are modulated by lexical frequency. Previous research has demonstrated that during lexical access, the processing of high frequency words is facilitated; in contrast, during phonetic encoding, the properties of low frequency words are enhanced. These contrasting effects provide the opportunity to distinguish two theoretical perspectives on how interaction between processing levels can be increased. A theory in which cascading activation is used to increase interaction predicts that the facilitation of high frequency words will enhance their influence on the phonetic properties of speech errors. Alternatively, if interaction is increased by integrating levels of representation, the phonetics of speech errors will reflect the retrieval of enhanced phonetic properties for low frequency words. Utilizing a novel statistical analysis method, we show that in experimentally induced speech errors low lexical frequency targets and outcomes exhibit enhanced phonetic processing. We sketch an interactive model of lexical, phonological and phonetic processing that accounts for the conflicting effects of lexical frequency on lexical access and phonetic processing. 相似文献

Both male-to-female transsexuals and advanced prostate cancer (PCa) patients are treated with androgen-suppressing drugs that have emasculating effects. Additionally, transsexuals take estrogenic compounds to feminize their bodies. We explore the quality of life of these populations, based on interviews with 12 individuals from each group. Overall, the transsexuals had a better psychological response to chemical castration than the PCa patients. The transsexuals showed more enthusiasm about the changes in their life; they viewed their lives as beginning anew, accepted their reduced libido, and were more comfortable with their increased emotionality. Different responses in the two groups are not surprising given that they undergo androgen deprivation under very different medical contexts. However, the fact that the transwomen are able to conceptualize the effects as positive suggests that some androgen-deprived PCa patients may benefit from reconceptualizing their changes within a positive framework. Additionally, difference in the two populations may be attributed, in part, to the fact that the transsexuals take supplemental estrogen. Circumstantial evidence suggests that estrogen in androgen-deprived males may improve sleep quality, help retain sexual interest, and protect cognitive function. This suggests that PCa patients may benefit from using estradiol for androgen suppression. 相似文献

Aim: This study considers the question of whether inpatient admission for anorexia nervosa was a therapeutic experience for two women with chronic anorexia nervosa. The question of whether inpatient admission for anorexia nervosa can be therapeutic is not answerable through existing research evidence. Method: The women were interviewed about their experience of having anorexia, its impact on their lives and the treatment they received. The interviews involved learning about the women's experiences by listening to their stories rather than asking them direct questions about what has been therapeutic about their treatment. Analysis: Their narratives were used to develop understanding grounded in experience and were analysed using a narrative thematic analysis. Ideas, themes and connections were noted but not coded as found in some forms of thematic analysis. Discussion: Consideration is given to the therapeutic qualities of the treatments the women received and the place of therapeutic inpatient admission. The central theme of this research was ‘relationships’ which indicates the use of therapeutic approaches that emphasise the importance of the therapeutic relationship in the treatment of chronic anorexia nervosa. It is suggested that psychodynamic and attachment theories should be used to inform overall treatment models. Some important issues for service provision and areas for further research are identified. 相似文献

Group diversity researchers are often faced with the problem of calculating diversity indices for groups that are incomplete
due to participant nonresponse. Because participant nonresponse may attenuate the correlations that are observed between group
diversity scores and outcome variables, some researchers use group-retention rules based on within-group response rates. With
this approach, only those groups that have a within-group response rate at, or higher than, the rate prescribed by the group-retention
rule are retained for subsequent analyses. We conducted two sets of experiments using computer simulations to determine the
usefulness of group-retention rules. We found that group-retention rules are not a substitute for a high response rate and
may decrease the accuracy of observed relations, and consequently, we advise against their use in diversity research. 相似文献

A core theme of social psychology is that perceivers can shape targets’ future behaviors through self‐fulfilling prophecies. Self‐fulfilling prophecies occur when perceivers’ false beliefs about targets initiate a sequence of events that ultimately cause targets to exhibit expectancy‐consistent behaviors, thereby causing perceivers’ initially false beliefs to become true. This article reviews theory and research relevant to self‐fulfilling prophecies with particular foci on the underlying mechanisms that produce self‐fulfilling prophecies, the power of self‐fulfilling prophecies to alter behavior, and the extent to which self‐fulfilling prophecies contribute to social problems. 相似文献

It has been suggested that space, time and number are represented on a common subjective scale. Saccadic eye movements provide a fascinating test. Saccades compress the perceived magnitude of spatial separations and temporal intervals to approximately half of their true value. The question arises as to whether saccades also compress number. They do, and compression follows a very similar time course for all three attributes: it is maximal at saccadic onset and decreases to veridicality within a window of approximately 50ms. These results reinforce the suggestion of a common perceptual metric, which is probably mediated by the intraparietal cortex; they further suggest that before each saccade the common metric for all three is reset, possibly to pave the way for a fresh analysis of the post-saccadic situation. 相似文献

Danger Ideation Reduction Therapy (DIRT) is a cognitive treatment package developed in the mid-1990s to treat obsessive-compulsive (OC) washing. DIRT is solely directed at decreasing threat expectancies and does not involve direct or indirect exposure. The effectiveness of the DIRT package for OC washers has been examined, and to date a number of publications, including two randomised controlled trials, support its efficacy. Recently, the DIRT package was modified to treat people with the OC checking subtype. In the current study, three adult OC checkers received DIRT in 12 to 14 individual 1-hr sessions conducted by a clinical psychologist. At posttreatment, substantial and clinically significant reductions in scores on a range of standardized outcome measures of obsessive-compulsive disorder symptom severity were apparent for all three participants. Crucially, these improvements were maintained at 4-month follow-up. Although further research is clearly warranted, these preliminary findings suggest that DIRT for checkers may prove as effective as DIRT for OC washers. 相似文献

Exploratory factor analysis (EFA) has become a common procedure in educational and psychological research. In the course of
performing an EFA, researchers often base the decision of how many factors to retain on the eigenvalues for the factors. However,
many researchers do not realize that eigenvalues, like all sample statistics, are subject to sampling error, which means that
confidence intervals (CIs) can be estimated for each eigenvalue. In the present article, we demonstrate two methods of estimating
CIs for eigenvalues: one based on the mathematical properties of the central limit theorem, and the other based on bootstrapping.

Although the Müller‐Lyer, Poggendorff and Zöllner figures and the illusions with which they are associated– those of length, misalignment and non‐parallelism, respectively – are quite different, all three are attributable to the same basic effect, that of the difference in the apparent length of equal lines forming acute and obtuse angles. The role of this basic affect, reported originally by Müller‐Lyer but overlooked by him and others as a possible cause of the three illusions, is identified and discussed. It is suggested that the demonstration of a basic stimulus condition (acute and obtuse angles) and its associated illusion (difference in apparent length) generating a class of “higher order” geometric illusions has implications not only for a closer understanding of the three illusions under consideration but for other classes of illusory phenomena that might also share a common basis. 相似文献
