We aimed to assess which comorbid problems (oppositional defiant behaviors, anxiety, autistic traits, motor coordination problems,
and reading problems) were most associated with Attention-Deficit/Hyperactivity Disorder (ADHD); to determine whether these
comorbid problems shared executive and motor problems on an endophenotype level with ADHD; and to determine whether executive
functioning (EF)—and motor-endophenotypes supported the hypothesis that ADHD with comorbid problems is a qualitatively different
phenotype than ADHD without comorbid problems. An EF—and a motor-endophenotype were formed based on nine neuropsychological
tasks administered to 816 children from ADHD—and control-families. Additional data on comorbid problems were gathered using
questionnaires. Results indicated that oppositional defiant behaviors appeared the most important comorbid problems of ADHD,
followed by autistic traits, and than followed by motor coordination problems, anxiety, and reading problems. Both the EF—and
motor-endophenotype were correlated and cross-correlated in siblings to autistic traits, motor coordination problems and reading
problems, suggesting ADHD and these comorbid problems may possibly share familial/genetic EF and motor deficits. No such results
were found for oppositional defiant behaviors and anxiety. ADHD in co-occurrence with comorbid problems may not be best seen
as a distinct subtype of ADHD, but further research is warranted.

A publishing cohort of Kleinian analysts – Rosenfeld, Segal and Bion – implemented Klein's (1946) notions of projective identification and the 'paranoid ' and 'schizoid ' positions in the understanding of a group of psychotic disorders. The author differentiates Klein's (1946) Notes on some schizoid mechanisms paper from its revised version of 1952, maintaining that it was Rosenfeld's clinical work during this period that helped to centralize Klein's redefinition of projective identification. The stage was set for Segal 's contribution in terms of 'symbolic equations,' where the psychotic's attack on the breast left him incarcerated in internal torment and persecution, where things-in-themselves were confused with what they symbolically represented. Segal in turn linked psychotic to normal, paranoid–schizoid to depressive positions, where by means of projective identification and symbolic imagination, the patient could arouse feelings in the analyst related to sadness, guilt and loss. Bion assumed that psychotic pathology reflected disordered thinking, when the severely disturbed used language as a mode of action. The psychotic was profoundly confused between the use of thought and action in the natural world – where thought was required, he preferred action and vice versa. Bion also drew upon projective identification in a new, broader way, so that analysis could now become more of an intersubjective, bi-directional field of projective and communicational influence between patient and analyst. The paper concludes with the impact of the work of Rosenfeld, Segal and Bion and variations on the technique of analyzing psychotic states in terms of the patient's early history, transference and countertransference. 相似文献

Previous studies of tactile acuity on the fingertip, using passive touch, have demonstrated an age-related decline in spatial resolution for both sighted and blind subjects. We have reexamined this age dependence with two newly designed tactile-acuity charts that require active exploration of the test symbols. One chart used dot patterns similar to braille, and the other used embossed Landolt rings. Groups of blind braille readers and sighted subjects ranging from 12 to 85 years old were tested in two experiments. We replicated previous findings for sighted subjects by showing an age-related decrease in tactile acuity by nearly 1% per year. Surprisingly, the blind subjects retained high acuity into old age, showing no age-related decline. For the blind subjects, tactile acuity did not correlate with braille reading speed, the amount of daily reading, or the age at which braille was learned. We conclude that when measured with active touch, blind subjects retain high tactile acuity into old age, unlike their aging sighted peers. We propose that blind people's use of active touch in daily activities, not specifically braille reading, results in preservation of tactile acuity across the life span. 相似文献

Ben-Gurion University of the Negev, Beer Sheva, Israel In three experiments, we examined the effects of prime-target stimulus onset asynchrony (SOA) and the proportion of related primes and targets (relatedness proportion, or RP) on semantic priming when the prime was either named or was searched for a specific letter. In Experiment 1, with an RP of. 50, priming occurred at SOAs of 240 and 840 msec when the prime was named, but no priming was found at either SOA when the prime was searched for a letter. In Experiment 2 the RP was either. 20 or. 80, and the SOA was set at 1, 700 msec; priming again was found in both conditions when the prime was named, but only in the RP.80 condition when a letter search task was performed on the prime. In Experiment 3, both the proportion of related trials and SOA were varied; as in the previous experiments, no priming effects were found with the letter search task for either SOA in the RP.20 condition, but the priming effect was reinstated in the RP.80 condition. These results are discussed with respect to how limited capacity resources are allocated and how they influence semantic priming effects. 相似文献

Despite the prevalence of psychiatric disorders in medical settings, mental health problems often go undetected and patients do not receive appropriate treatment. The main goal of this study is to provide additional information about the Beck Anxiety Inventory – Primary Care (BAI–PC), a brief instrument that screens for patients with anxiety. This study provides information on the performance of the BAI–PC as a screening instrument for depression and PTSD in addition to its original purpose as a screening instrument for anxiety. This efficient tool can identify patients who can benefit from effective psychological treatments and facilitate referrals to psychologists working in medical settings. 相似文献

Inattentive behavior is considered a core and pervasive feature of ADHD; however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory deficits and inattentive behavior. The current study investigated whether inattentive behavior in children with ADHD is functionally related to the domain-general central executive and/or subsidiary storage/rehearsal components of working memory. Objective observations of children’s attentive behavior by independent observers were conducted while children with ADHD (n?=?15) and typically developing children (n?=?14) completed counterbalanced tasks that differentially manipulated central executive, phonological storage/rehearsal, and visuospatial storage/rehearsal demands. Results of latent variable and effect size confidence interval analyses revealed two conditions that completely accounted for the attentive behavior deficits in children with ADHD: (a) placing demands on central executive processing, the effect of which is evident under even low cognitive loads, and (b) exceeding storage/rehearsal capacity, which has similar effects on children with ADHD and typically developing children but occurs at lower cognitive loads for children with ADHD. 相似文献
