Kaplan RM 《The American psychologist》2007,62(3):217-219
This issue of the American Psychologist (April 2007) includes two reviews of the literature on the effects of behavioral programs to reduce body weight. One review (T. Mann et al., 2007) concentrates on dietary interventions and finds little evidence that diets are of benefit. The second review (L. H. Powell, J. E. Calvin III, & J. E. Calvin Jr., 2007) concentrates on multicomponent interventions and reports some significant achievements of behavioral interventions. Although the reviews come to different conclusions about the value of supporting weight loss interventions, there appears to be agreement that diet alone results in little or no long-term benefit. Evidence-based multicomponent behavioral interventions or interventions that combine behavioral with medical or surgical treatments may offer better chances of long-term weight control. Evidence-based studies are needed to inform policy on provider reimbursement for weight loss programs. 相似文献

This study tests the hypothesis that dyslexia and dyscalculia are associated with two largely independent cognitive deficits, namely a phonological deficit in the case of dyslexia and a deficit in the number module in the case of dyscalculia. In four groups of 8- to 10-year-olds (42 control, 21 dyslexic, 20 dyscalculic, and 26 dyslexic/dyscalculic), phonological awareness, phonological and visual-spatial short-term and working memory, naming speed, and basic number processing skills were assessed. A phonological deficit was found for both dyslexic groups, irrespective of additional arithmetic deficits, but not for the dyscalculia-only group. In contrast, deficits in processing of symbolic and nonsymbolic magnitudes were observed in both groups of dyscalculic children, irrespective of additional reading difficulties, but not in the dyslexia-only group. Cognitive deficits in the comorbid dyslexia/dyscalculia group were additive; that is, they resulted from the combination of two learning disorders. These findings suggest that dyslexia and dyscalculia have separable cognitive profiles, namely a phonological deficit in the case of dyslexia and a deficient number module in the case of dyscalculia. 相似文献

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia. 相似文献

This paper praises and criticizes Peter-Paul Verbeek’s What Things Do (2006). The four things that Verbeek does well are: (1) remind us of the importance of technological things; (2) bring Karl Jaspers
into the conversation on technology; (3) explain how technology “co-shapes” experience by reading Bruno Latour’s actor-network
theory in light of Don Ihde’s post-phenomenology; (4) develop a material aesthetics of design. The three things that Verbeek
does not do well are: (1) analyze the material conditions in which things are produced; (2) criticize the social-political
design and use context of things; and (3) appreciate how liberal moral-political theory contributes to our evaluation of technology. 相似文献

Two experiments with 3½‐ to 6½‐year‐old children showed that theory‐of‐mind development is associated with the growth of episodic memory. Episodic memory was assessed by manipulating informational conditions such that they permit or prevent the formation of episodic memories in terms of re‐experiencing the recalled event. Only experienced events, e.g. seeing how one puts a picture of a frog into a box, can be remembered by re‐experience. Events known through indirect information cannot be re‐experienced, e.g. putting pictures into the box when blindfolded and being later shown on video what was on these cards. Children were also tested on a battery of theory‐of‐mind tasks assessing their understanding of the origins of knowledge. There was a significant interaction in both experiments showing that recall of directly experienced items improved in relation to indirectly presented items the higher children's theory‐of‐mind scores. The discussion suggests that episodic memory development is specifically linked to the growing ability to introspect an ongoing experience and interpret it as representing an actual past event.

The present research provided a test of the Ferris, Buckley, and Allen (1992) model depicting the antecedents and consequences of promotion systems in organizations. A 2-study design is utilized to investigate the role of promotion system characteristics as mediating the relationship between organizational factors, environmental factors, and job factors/employee characteristics and perceptions of organizational justice and advancement opportunity. Results provide convergence of support for the model across both studies. Implications of the results and directions for future research are discussed. 相似文献

Orthodox Probabilists hold that an inquirer ought to harbor a precise degree of confidence in each hypothesis about which
she is concerned. Modest Probabilism is one of a family doctrines inspired by the thought that Orthodox Probabilists are thereby
demanding that an inquirer effect a precision that is often unwarranted by her evidence. The purpose of this essay is (i)
to explain the particular way in which Modest Probabilism answers to this thought, and (ii) to address an alleged counterexample
to Modest Probabilism meant to offer proof that Modest Probabilism is no better than its orthodox predecessor at avoiding
unwarranted precision. 相似文献

Life cycle and loss--the spiritual vacuum of heroin addiction 总被引:1,自引:0,他引:1
This research studied the function of heroin addiction as a family-learned method of coping with death, separation, and loss across the life cycle. Heroin addicts, psychiatric outpatients, and normal students were given an extensive interview and test battery to determine the incidence of loss of family members and significant others. Because the impact of death is often overcome through religious rituals, this study also investigated the subjects' perception of their families' religious values and orientation to life's meaning and purpose. Results indicate that the incidence of death differs significantly across groups and that addicts have a distinct orientation to death, are more suicidal, and have more premature and bizarre death experiences. During childhood they have more family separations, and they tend to develop a distinct pattern of continuously separating from and returning to their families. They are also less likely to have a clearly defined purpose in life. A subset of parents from each group were also interviewed and tested, and these results support the theory of the intergenerational transmission of behavior. 相似文献
