Poor performance on tests of reading comprehension could be the result of weak word-recognition skills, inconsistent attention (ADD), or a combination of the two. Identifying the source of the reading disability (RD) reliably has been difficult because inconsistent attention interferes with reading and weak word recognition skill makes attention wander. The situation is further complicated by the fact that there are no objective diagnostic tests for ADD (Breggin, 1998; Diller, 1998). We proposed a new model of differential diagnosis of ADHD-I/RD and field-tested its utility in two studies. The new diagnostic procedure utilizes intra-individual differences seen in the performance of at-risk learners on tasks related to reading that vary in the degree of sustained attention required for successful performance. The hypothesis is that children whose attention is inconsistent would perform more poorly on tests such as listening comprehension, which require sustained attention, than on tests such as reading comprehension, which are more tolerant of inattention. Such differences will not be seen in the test scores of children who have only a reading disability because their performance on reading tests is determined more by the difficulty level of the tests than by the sensitivity of the tests to attention. The validity of this new model was evaluated by determining the relationship between differences seen in the scores of tests that differ in their attention requirement and the degree of inconsistency in sustained attention as measured by Conners' CPT. The results of the two studies indicate this to be a viable approach. The results of the second study are presented in this report. 相似文献

Asymmetrical gait patterns such as the gallop provide insight into the complexity of human locomotion. The nature of spontaneous (e.g., walk-run), quasi-spontaneous (e.g., gallop-walk), and intentional (e.g., walk-gallop) transitions was analyzed in 2 ways in the present study. In Analysis 1, the authors used step-wise regression to associate 10 physical characteristics with gait transitions. Transition predictability was moderate; thigh length best predicted 3 of 6 transitions. In Analysis 2, the dynamic characteristics of transitions (order parameters, phase shifts, multistability, and critical fluctuations) were described; those characteristics existed for all transition types. The results of the analyses suggest that intentional transitions are less biomechanically predictable than are spontaneous transitions and that transitions between gait pairs (e.g., walk-gallop and gallop-walk), regardless of velocity direction, have more in common than do transitions requiring specific intention. 相似文献

Fifty-six heroin addicts and 60 age-matched controls were offered choices between monetary rewards ($11-$80) available immediately and larger rewards ($25-$85) available after delays ranging from 1 week to 6 months. Participants had a 1-in-6 chance of winning a reward that they chose on one randomly selected trial. Delay-discounting rates were estimated from the pattern of participants' choices. The discounting model of impulsiveness (Ainslie, 1975) implies that delay-discounting rates are positively correlated with impulsiveness. On average, heroin addicts' discount rates were twice those of controls (p = .004), and discount rates were positively correlated with impulsivity as measured by self-report questionnaires (p < .05). The results lend external validity to the delay-discounting rate as a measure of impulsiveness, a characteristic associated with substance abuse. 相似文献

Two studies investigated the effect of income source and race on ratings of and objections to potential neighbors. Equivalent amounts of income from different sources included work only, work and public assistance, or work and a small inheritance. The race variable included African American, European American, or Hispanic. Subjects for Study 1 were undergraduate psychology students. Subjects for Study 2 were homeowners. Class bias was not a symbolic way to express race bias. There was a clear distinction between class bias and race bias in expression and function. Results indicate that class bias was used when subjects gave ratings of new neighbors. These biased ratings do not correlate with measures of racism. Furthermore, results indicate that objections to the new neighbors were more frequent for those gaining income from sources other than work. The findings indicate that class prejudice based on income source is primary and openly expressed, whereas racial prejudice does not appear as an important contributing factor in this context. 相似文献

Borderline personality disorder (BPD) is characterized by tumultuous, unstable personal relationships, difficulty being alone, and an inability to self-soothe. This may explain why patients with BPD tend to develop strong attachments to transitional objects such as stuffed animals. Research in hospital settings has linked the use of transitional objects to the presence of BPD. Using a nonclinical community sample (N = 80) we explored the link between attachments to transitional objects and various aspects of personality pathology, as well as to childhood trauma, and parental rearing styles. People who reported intense current attachments to transitional objects were significantly more likely to meet criteria for a BPD diagnosis than those who did not; they also reported more childhood trauma, rated their early caregivers as less supportive, and had more attachment problems as adults. Heavy emotional reliance on transitional objects in adulthood may be an indicator of underlying pathology, particularly BPD. 相似文献

In addition to the potential for ongoing health concerns, adolescent and young adult (AYA) childhood cancer survivors frequently
report posttraumatic stress symptoms (PTSS). The current study examines whether beliefs about health moderate the relationship
between the number of health problems and PTSS 2 months later in 140 survivors. Beliefs, as measured by scales of the Health
Competence Beliefs Inventory (HCBI), negatively related to PTSS while health problems positively related to PTSS. Three scales
of the HCBI-health perceptions, satisfaction with healthcare and cognitive competence—were significant moderators. The relationship
between health problems and PTSS was stronger in the presence of less adaptive beliefs. These beliefs represent potentially
malleable intervention targets for reducing PTSS in childhood cancer survivors. 相似文献

There is professional consensus that teleanalysis, the practice of psychoanalysis conducted remotely using the telephone and the Internet, is increasing in response to more mobility in the population. But there is controversy as to whether the use of technology leads to a dilution of analysis or to adaptive innovation that is clinically effective and true to the tenets of psychoanalysis. The author reviews the psychoanalytic literature and shows the development of analytic thinking about this technology-assisted practice of psychoanalysis. She summarizes analysts' perceptions and experiences of the advantages and disadvantages, and considers the indications and contra-indications. She focuses on the clinical concerns that arise in terms of the frame, resistance, and the development of analytic process through the unconscious communication of internal objects, unconscious fantasy, transference and countertransference. She gives vignettes from the analysis of a man with trauma-related depression to address the concerns raised and to support her argument that analysis using the telephone and the Internet is a viable, clinically effective alternative to traditional analysis where necessary. 相似文献
