Global mobility for psychologists is rapidly improving because of an emerging consensus on recognition standards, the demand for cross-border mobility both internal and external to the profession, and the efforts of membership, credentialing, and regional organizations to promote mobility. In the United States, multiple credentialing organizations promote mobility, primarily through individual endorsement of credentials. The Canadian regulatory boards signed a mutual recognition agreement implementing fast-track mechanisms for licensed psychologists seeking mobility and a competency-based assessment for initial registration. Europe plans to reduce barriers to mobility through mutual recognition of qualifications via a EuroPsy diploma that provides a benchmark for professional psychology education and training. Other regions have not made as much progress with regard to promoting mobility, as many do not yet even regulate the practice of psychology. The authors examine who seeks mobility, which geographic regions promote mobility, and by which mechanisms.  相似文献

When analysands read about themselves in reports, their reactions range from anger, disappointment, or condemnation to a sense of appreciation or even idealization of the analyst. The eleven interviews reported here reflect only conscious responses; the unconscious layers were not probed for. It should be kept in mind also that the analysts of these patients might report very different stories. Other limitations are the small sample size and the representation only of patients who volunteered. Nonetheless, the information they provide may help analysts consider how and when writing about patients may influence their representation of themselves, the analyst, and analysis itself.  相似文献

This study examined the relations between maternal criticism and externalizing and internalizing symptoms in adolescents who varied in their risk for psychopathology. Both maternal-effects and child-effects models were examined. The sample consisted of 194 adolescents (mean age = 11.8~years) and their mothers; 146 mothers had a history of depressive disorders and 48 did not. When adolescents were in 6th and 8th grade, maternal criticism was measured with the five-minute speech sample and adolescents symptoms were assessed with the Child Behavior Checklist. Maternal criticism was significantly associated with both adolescents externalizing and internalizing symptoms, beyond the contribution of the chronicity/severity of mothers depression history. Maternal criticism did not mediate the relation between maternal depression and adolescent symptoms. In contrast, adolescent externalizing behaviors mediated the relation between chronicity/severity of maternal depression history and maternal criticism in 6th grade. Prospective analyses showed that adolescents externalizing symptoms in 6th grade significantly predicted maternal criticism in 8th grade, controlling for maternal depression history and prior maternal criticism. Results are discussed in terms of the importance of examining child-effects models in studies of maternal criticism.  相似文献

The ability to remember visual stimuli over a short delay period is limited by the small capacity of visual working memory (VWM). Here the authors investigate the role of learning in enhancing VWM. Participants saw 2 spatial arrays separated by a 1-s interval. The 2 arrays were identical except for 1 location. Participants had to detect the difference. Unknown to the participants, some spatial arrays would repeat once every dozen trials or so for up to 32 repetitions. Spatial VWM performance increased significantly when the same location changed across display repetitions, but not at all when different locations changed from one display repetition to another. The authors suggest that a major role of learning in VWM is to mediate which information gets retained, rather than to directly increase VWM capacity.  相似文献

This study evaluated 2 methods of disseminating an empirically validated smokeless tobacco intervention delivered during routine dental care. Twenty cities within 12 states were stratified and then randomized to 1 of 3 groups: personalized instruction (PI), self-study (SS), or delayed training (DT) control. Dental hygienists in the SS condition were sent a manual and video. Those in the PI condition were recruited to attend a workshop. Thirty-seven percent of eligible hygienists agreed to participate. At 12 months postenrollment, hygienists in the SS and PI conditions significantly increased their "Assist" behaviors (discuss cessation techniques, help patient set a quit date, and provide cessation materials) and reported fewer perceived barriers to delivering the intervention as compared with hygienists in DT. An economic analysis suggests that SS is more cost-effective than PI.  相似文献

Performance on a covert visual attention task is compared between a group of adults with developmental dyslexia (specifically phonological difficulties) and a group of age and IQ matched controls. The group with dyslexia were generally slower to detect validly-cued targets. Costs of shifting attention toward the periphery when the target was invalidly cued were significantly higher for the group with dyslexia, while costs associated with shifts toward the fovea tended to be lower. Higher costs were also shown by the group with dyslexia for up-down shifts of attention in the periphery. A visual field processing difference was found, in that the group with dyslexia showed higher costs associated with shifting attention between objects in they LVF. These findings indicate that these adults with dyslexia have difficulty in both the space-based and the object-based components of covert visual attention, and more specifically to stimuli located in the periphery.  相似文献

The extent to which the Comprehensive System for the Rorschach is reliably scored has been a topic of some controversy. Although several studies have concluded it can be scored reliably in research settings, little is known about its reliability in field settings. This study evaluated the reliability of both response-level codes and protocol-level scores among 84 adolescent psychiatric inpatients in a clinical setting. Rorschachs were originally administered and scored for clinical purposes. Among response codes, 87% demonstrated acceptable reliability(> .60), and most coefficients exceeded .80. Results were similar for protocol-level scores, with only one score demonstrating less than adequate reliability. The findings are consistent with previous evidence, indicating reliable scoring is possible even in field settings.  相似文献

No facet of human development is more crucial than becoming symbol-minded. To participate fully in any society, children have to master the symbol systems that are important in that society. Children today must learn to use more varieties of symbolic media than ever before, so it is even more important to understand the processes involved in symbolic development. Recent research has greatly expanded what we know about early symbol use. We have learned, for example, that infants initially accept a wide range of entities as potential symbols and that young children are often confused about the nature of symbol-referent relations. During the first few years of life, however, children make rapid progress towards becoming competent symbol users.  相似文献
