The clinical psychologist as tester in the diagnostic triad (patient, referring person, and tester) may have the role of a technician or consultant. As a technician, he is concerned with comparing the patient with others (diagnostic categorization); as a consultant, he attempts to understand the patient—to develop and evaluate hypotheses on the basis of the patient's behavior (rather than in getting test responses from him). "The important differences between these two roles arise from the differences in the position or orientation of the psychologists in them… . Theoretically the kinds of activity in which the clinician cannot be replaced by the cookbook represent the limits of computing machines, of which the cookbook is a special case." It is the role of technician "that requires the use of cookbooks." (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

In this report, we describe the cloning and characterization of Boo, a novel anti-apoptotic member of the Bcl-2 family. The expression of Boo was highly restricted to the ovary and epididymis implicating it in the control of ovarian atresia and sperm maturation. Boo contains the conserved BH1 and BH2 domains, but lacks the BH3 motif. Like Bcl-2, Boo possesses a hydrophobic C-terminus and localizes to intracellular membranes. Boo also has an N-terminal region with strong homology to the BH4 domain found to be important for the function of some anti-apoptotic Bcl-2 homologues. Chromosomal localization analysis assigned Boo to murine chromosome 9 at band d9. Boo inhibits apoptosis, homodimerizes or heterodimerizes with some death-promoting and -suppressing Bcl-2 family members. More importantly, Boo interacts with Apaf-1 and forms a multimeric protein complex with Apaf-1 and caspase-9. Bak and Bik, two pro-apoptotic homologues disrupt the association of Boo and Apaf-1. Furthermore, Boo binds to three distinct regions of Apaf-1. These results demonstrate the evolutionarily conserved nature of the mechanisms of apoptosis. Like Ced-9, the mammalian homologues Boo and Bcl-xL interact with the human counterpart of Ced-4, Apaf-1, and thereby regulate apoptosis.  相似文献

This study examined the relationships among visuospatial working memory (WM) executive functioning, and spatial abilities. One hundred sixty-seven participants performed visuospatial short-term memory (STM) and WM span tasks, executive functioning tasks, and a set of paper-and-pencil tests of spatial abilities that load on 3 correlated but distinguishable factors (Spatial Visualization, Spatial Relations, and Perceptual Speed). Confirmatory factor analysis results indicated that, in the visuospatial domain, processing-and-storage WM tasks and storage-oriented STM tasks equally implicate executive functioning and are not clearly distinguishable. These results provide a contrast with existing evidence from the verbal domain and support the proposal that the visuospatial sketchpad may be closely tied to the central executive. Further, structural equation modeling results supported the prediction that, whereas they all implicate some degree of visuospatial storage, the 3 spatial ability factors differ in the degree of executive involvement (highest for Spatial Visualization and lowest for Perceptual Speed). Such results highlight the usefulness of a WM perspective in characterizing the nature of cognitive abilities and, more generally, human intelligence.

Confusion exists regarding the developmental ages of numerous Asian and southeast Asian Homo erectus fossils because of Weidenreich's contention that Pithecanthropus fused its sutures prematurely relative to H. sapiens. I reevaluate the cranial developmental ages of the Ngandong "juveniles" (2, 5, 8, 9) based on a series of indicators of youth (superstructure development, suture development/fusion, and cranial thickness) and cranial contours. The Ngandong juveniles are compared with H. sapiens adults (n = 281) and subadults (n = 81) and with Ngandong and other H. erectus adults (n = 20) and subadults (n = 4). Cranial contours are assessed using bivariate plots of arc vs. chord measurements. All indicators suggest that Ngandong 5 and 9 are adults, whereas Ngandong 8 is an older juvenile or young adult and Ngandong 2 is a juvenile with a developmental age range of greater than 6 and less than 11 years. In addition, adult cranial contours and the pattern of contour development are similar between Ngandong adults and other H. erectus adults. There is nothing in the cranial contour data to suggest that Ngandong is, despite a relatively large brain, transitional in vault shape between H. erectus and H. sapiens.  相似文献

STUDY OBJECTIVES: This study provides estimates of reliability for aggregated values from 1 to 7 recording nights for five commonly used actigraphic measures of sleep patterns, reliability as a function of night type (weeknight or weekend night), and stability of measures over several months. DESIGN AND SETTING: Data are from three studies that obtained 7 nights of actigraph data (using Mini Motionlogger actigraphs and associated validated algorithms [ASA]) on children and adolescents living at home on self-selected sleep-wake schedules. PARTICIPANTS: Participants were 169 children aged 12-60 months, and 55 adolescents aged 11-16 years. MEASUREMENTS AND RESULTS: Up to 28% of weekly recordings may be unacceptable for analysis in young participants because of illness, technical problems, and participant noncompliance; studies aiming to collect 5 nights of actigraph data should record for at least 1 full week. Reliability estimates for values aggregated over any 5 nights were adequate (> or = .70) for sleep start time, wake minutes, and sleep efficiency. Measures of sleep minutes and sleep period were less reliable and may require 7 or more nights for estimates of stable individual differences. Reliability for 1- or 2-night aggregates were poor for all measures. We found significant and high correlations between summer and fall session measures for all five variables when weekend nights were included. CONCLUSIONS: Five or more nights of usable recordings are required to obtain reliable actigraph measures of sleep for children and adolescents.  相似文献

This article argues that in-group favoritism occurs on positive and negative dimensions only when the dimensions of comparison provide an appropriate and meaningful basis for self–other definition, that is, when traits comparatively and normatively fit in-group–out-group categorizations. Three studies are reported in which groups were evaluated on positive or negative traits that varied in their degree of normative fit to in-group and out-group identity. In line with predictions, fit rather than stimulus valence was the crucial determinant of (1) in-group favoritism and (2) absolute level of differentiation between groups. Implications of the findings for explanations of positive–negative asymmetry and broader understandings of intergroup discrimination are discussed.

Testing spatial memory within the same environment used for learning produces interference between one's immediate representation of current position and the to-be-retrieved position. In a series of 3 experiments, we show that “current position” and its influence on memory performance can be driven by conceptual factors in an ambiguous testing situation. First, we demonstrate that simple instructions about the testing conditions—“you are in the space” versus “imagine the space”—determined whether a participant showed interference from current position, reflecting the effect of one's conceived position in space on long-term memory retrieval. In addition, we show that when instructions motivate this use of current position under ambiguous conditions, the position assumed is defined by the last known position rather than the learning position. We account for these results by suggesting that current models of spatial memory need to incorporate both the perceptual and conceptual testing environment, malleable versus stable features, and the interaction of current position with long-term memory.

The authors analyzed whether the relation between maternal child-rearing behaviors and a child's self-regulation was mediated by the accuracy in the child's perceptions of the mother's goals and methods and by the direction of attributions for the mother's intentions. Sixty mothers with children 7–10 years old were asked how and why they would react in 15 hypothetical situations. Children were interviewed to assess the accuracy of their perceptions and the direction of their attributions. To assess the children's self-regulation, mothers and children were observed planning an excursion. LISREL analysis showed that the reported use of both control and demandingness and of responsiveness has a positive influence on the accuracy of children's perceptions and, in turn, on their self-regulation. However, part of the positive impact of control and demandingness on children's self-regulation was due to the effect of positive attributions on the accuracy of perceptions.

In an attempt to answer the question, "what is affect?", this paper considers Freud's metapsychological formulation in the light of recent developments in psychoanalysis and neuroscience. It argues that the problem of affect-perhaps more than any other-forces us to acknowledge the intrinsic connexion between mind and body, and to accommodate it in our theoretical formulations. A review of the problem from this point of view leads to the following formulation: affect is a primary sensory modality, analogous to the senses of vision, hearing, somatic sensation, taste, and smell. These modalities are the elementary constituents of the envelope of consciousness, from which it is impossible to free ourselves. Whereas the sensory modalities of vision, hearing, somatic sensation, taste, and smell represent aspects of the external object world ("unknowable" in itself), affect is the primary sensory modality through which we perceive as aspect of the internal world of the subject ("unconscious" in itself).  相似文献

This study investigated how culture influences the association between autobiographical memory retrieval and depression. Thirty clinically depressed patients and 30 controls, 15 each from Britain and Taiwan, completed the English and Chinese versions of the Autobiographical Memory Cueing Task (AMT). Overall, the depressed individuals from both cultural groups retrieved significantly fewer specific and more categoric autobiographical memories than their matched, nondepressed controls. Within the control groups, the British participants retrieved significantly more specific autobiographical memories and fewer categoric memories than their Taiwanese counterparts. These results suggest that difficulty in retrieving specific autobiographical memories typical of depression may be a cognitive bias that occurs across cultures.

This study surveyed elementary school teachers in Melbourne, Australia to investigate their knowledge about attention-deficit/hyperactivity disorder (ADHD) and its impact on their reported behavior toward and perceptions of children with ADHD. Consistent with previous international findings, teachers demonstrated good overall knowledge about ADHD, with strengths in knowledge of symptoms/diagnosis and weaknesses in knowledge of causes and treatments. To investigate how knowledge impacted reported behaviors and perceptions, teachers also read vignettes of children with ADHD symptoms and rated their reactions to these children. In general, teachers with high, and to some extent average, knowledge about ADHD reported more helpful behaviors (e.g., help-seeking for their students) and perceptions (e.g., perceive the benefit of behavioral and educational treatments). However, teachers with high and average knowledge also predicted that these children would be more disruptive in the classroom, and reported having less confidence in their ability to manage these children. Implications and need for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Previous anatomical studies demonstrated vagal innervation to the ovary and distal colon and suggested the vagus nerve has uterine inputs. Recent behavioral and physiological evidence indicated that the vagus nerves conduct sensory information from the uterus to the brainstem. The present study was undertaken to identify vagal sensory connections to the uterus. Retrograde tracers, Fluorogold and pseudorabies virus were injected into the uterus and cervix. DiI, an anterograde tracer, was injected into the nodose ganglia. Neurectomies involving the pelvic, hypogastric, ovarian and abdominal vagus nerves were performed, and then uterine whole-mounts examined for sensory nerves containing calcitonin gene-related peptide. Nodose ganglia and caudal brainstem sections were examined for the presence of estrogen receptor-containing neurons in "vagal locales." Labeling of uterine-related neurons in the nodose ganglia (Fluorogold and pseudorabies virus) and in the brainstem nuclei (pseudorabies virus) was obtained. DiI-labeled nerve fibers occurred near uterine horn and uterine cervical blood vessels, in the myometrium, and in paracervical ganglia. Rats with vagal, pelvic, hypogastric and ovarian neurectomies exhibited a marked decrease in calcitonin gene-related peptide-immunoreactive nerves in the uterus relative to rats with pelvic, hypogastric, and ovarian neurectomies with intact vagus nerves. Neurons in the nodose ganglia and nucleus tractus solitarius were immunoreactive for estrogen receptors. These results demonstrated: (1) the vagus nerves serve as connections between the uterus and CNS, (2) the nodose ganglia contain uterine-related vagal afferent neuron cell bodies, and (3) neurons in vagal locales contain estrogen receptors.  相似文献

Growing public awareness of environmental hazards has led to an increased demand for public health authorities to investigate geographical clustering of diseases. Although such cluster analysis is nearly always ineffective in identifying causes of disease, it often has to be used to address public concern about environmental hazards. Interpreting the resulting data is not straightforward, however, and this paper presents a guide for the non-specialist. The pitfalls include the fact that cluster analyses are usually done post hoc, and not as a result of a prior hypothesis. This is particularly true for investigations prompted by reported clusters, which have the inherent danger of overestimating the disease rate through "boundary shrinkage" of the population from which the cases are assumed to have arisen. In disease surveillance the problem of making multiple comparisons can be overcome by testing for clustering and autocorrelation. When rates of disease are illustrated in disease maps undue focus on areas where random fluctuation is greatest can be minimised by smoothing techniques. Despite the fact that cluster analyses rarely prove fruitful in identifying causation, they may-like single case reports-have the potential to generate new knowledge.  相似文献

We examined the proposition that employees' work-flow centrality (i.e., the extent to which they are critical to the task-related interaction networks of their work groups) enhances their personal influence within their work groups and, therefore, motivates them to engage in voice behaviors. In support of this proposition, in a study of 184 bank employees nested within 42 work groups, we found that employees' work-flow centrality was positively related to voice behaviors, with their personal influence mediating this relationship. Further, work-flow centrality was more strongly related to personal influence when employees had higher task performance, and personal influence was more strongly related to voice behaviors when employees had higher levels of work-group identification. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Multiple ventricular septal defects: how and when should they be repaired?   总被引:1,自引:0,他引:1  
BACKGROUND: Congenital heart lesions with multiple ventricular septal defects remain a surgical challenge. Traditional approaches often rely on either ventriculotomy for exposure or palliation with pulmonary artery banding. However, indications for repair versus palliation and for various approaches to surgical exposure are not clearly defined. METHODS: From July 1992 to January 1998, 45 patients with multiple (>/=2) ventricular septal defects (37 with associated lesions) underwent surgery. Median age was 86 days; all but 4 patients were infants. The mean number of defects was 3.7, and almost half of the patients had more than 3 defects. Apical muscular defects were present in 62% of patients. Thirty-one patients underwent primary complete repair through a right atriotomy or trans-semilunar valve approach (group 1), 8 had palliation (group 2), and 6 underwent complete repair after prior palliation elsewhere (group 3). No patient had a ventriculotomy. RESULTS: One early death occurred in a group 1 patient. Four patients who had had palliation (50%) underwent early reoperation for pulmonary artery band revision because of failure to thrive or band removal after spontaneous closure of the defects. At follow-up (median 22 months), there was 1 death in a group 2 patient (palliation) and 1 other group 2 patient required cardiac transplantation. The only late reoperation was for removal of the pulmonary artery band and closure of multiple apical defects in a group 2 (palliation) patient. No patients who underwent repair have hemodynamically significant residual defects. CONCLUSIONS: In our experience, palliation of multiple ventricular septal defects is associated with greater morbidity than primary repair. Multiple defects can almost always be repaired adequately in early infancy without ventriculotomy, although "Swiss-cheese" septum may be an indication for palliation.  相似文献

The authors examined spatial frequency (SF) tuning of upright and inverted face identification using an SF variant of the Bubbles technique (F. Gosselin & P. G. Schyns, 2001). In Experiment 1, they validated the SF Bubbles technique in a plaid detection task. In Experiments 2a–c, the SFs used for identifying upright and inverted inner facial features were investigated. Although a clear inversion effect was present (mean accuracy was 24% higher and response times 455 ms shorter for upright faces), SF tunings were remarkably similar in both orientation conditions (mean r = .98; an SF band of 1.9 octaves centered at 9.8 cycles per face width for faces of about 6°). In Experiments 3a and b, the authors demonstrated that their technique is sensitive to both subtle bottom-up and top-down induced changes in SF tuning, suggesting that the null results of Experiments 2a–c are real. The most parsimonious explanation of the findings is provided by the quantitative account of the face inversion effect: The same information is used for identifying upright and inverted inner facial features, but processing has greater sensitivity with the former.

Comments on Michael Amrine's discussion of when is a doctor appropriately called doctor in the eyes of the press (American Psychologist, 1961, Vol. 16, p. 326). Insofar as the author can determine from years of reading the authoritative New York Times, a kind of compromise position has been taken by the editorial staff. Nonmedical doctorates of all types get their titular due in the paper's news columns. In the Sunday Book Review section, however, the various professorial PhD holders that write many of the reviews are strictly "Mister" as far as the editor is concerned. The MD reviewer on the other hand is always designated by title. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Organizational creativity is presented as four distinctly different sequential stages of a dynamic cognitive creative problem solving process: generation, conceptualization, optimization, and implementation. The generation stage is the activity that initiates the creative process. It is disruptive, because it entails proactively and deliberately seeking and discovering brand new problems and opportunities. Often called opportunity finding, generation results from restless discontent with the status quo. This activity is different from the second stage, conceptualization, which other researchers have previously described as problem construction, identification, or formulation. Such second stage activity gives definition to a newly discovered problem freshly emerging from the first stage or to a presented or otherwise already existing problem. We provide research showing that the people who prefer the generation stage activity (generators) are underrepresented in industrial and business organizations and are likely to be found in occupations normally found outside such organizations, for example, artists, writers, designers, teachers, and academic institutions. We argue that organizations seeking increased creativity and innovation could do so by understanding and recognizing the contributions made by people preferring the generator style, and by making generator activity more attractive for all members of the organization.

Seventy service people (waiters, bellhops, elevator operators, etc.) via a "… 'disguised unstructured interview'… " during the 1954 APA convention in New York were asked about the "… function of psychologists, the kind of people they were, and various aspects of their convention behavior." Psychologists are often confused with psychiatrists and are regarded primarily as therapists. Most of those interviewed "… think of us favorably on the whole, but two-thirds of them don't know who we are." (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

We investigated the effect of subliminally presented happy or angry faces on evaluative judgments when the facial muscles of participants were free to mimic or blocked. We hypothesized and showed that subliminally presented happy expressions lead to more positive judgments of cartoons compared to angry expressions only when facial muscles were not blocked. These results reveal the influence of socially driven embodied processes on affective judgments and have also potential implications for phenomena such as emotional contagion.
