We used fMRI to examine patterns of brain recruitment in 22 healthy seniors, half of whom had selective comprehension difficulty for grammatically complex sentences. We found significantly reduced recruitment of left posterolateral temporal [Brodmann area (BA) 22/21] and left inferior frontal (BA 44/6) cortex in poor comprehenders compared to the healthy seniors with good sentence comprehension, cortical regions previously associated with language comprehension and verbal working memory, respectively. The poor comprehenders demonstrated increased activation of left prefrontal (BA 9/46), right dorsal inferior frontal (BA 44/6), and left posterior cingulate (BA 31/23) cortices for the grammatically simpler sentences that they understood. We hypothesize that these brain regions support an alternate, nongrammatical strategy for processing complex configurations of symbolic information. Moreover, these observations emphasize the crucial role of the left perisylvian network for grammatically guided sentence processing in subjects with good comprehension. 相似文献

Attention and joint attention in preschool children with autism 总被引:13,自引:0,他引:13
Three experiments examined the role of attention in explaining dyadic (child-adult) and triadic (child-adult-object) joint attention difficulties in autism. Experiments 1 and 2 investigated children's ability to orient to an adult's attention bid and to follow the direction of a human or nonhuman cue. Experiment 3 tested ability to disengage and shift attention to objects. Results showed autism-specific difficulties at both dyadic and triadic levels. Children with autism were less responsive than developmentally delayed controls in orienting to attention bids and in following a human head-turn cue yet had no difficulty in shifting attention and were faster overall in orienting to targets. Results suggest a specific developmental delay in which children with autism rely on the presence of objects in the visual field to guide action. The relation between this problem and autistic children's difficulties with human communicative signals is discussed. 相似文献

Conclusion Robert Heinlein, author of Stranger in a Strange Land as well as countless other science fiction stories, once claimed that "The sole thing achieved by any privacy law is to make
the bugs smaller." Heinlein may be correct, but that travesties will happen does not sanction them—and maybe we will invent
bugs to root out and foil other bugs.
I have argued for individual privacy rights or rights to control sensitive personal information. The explosion of digital
technology has made possible severe violations of individual privacy by corporations, news agencies, and the government. If
I am correct about all of this, one commonly used "public interest" argument given for limiting privacy rights has been undermined.
It is also far from true to claim that the prevalence of strong encryption technology will lead to disaster. While I do not
adhere to the view that "rights hold, though the heavens may fall," in this article I have maintained that the security arguments
of law enforcement do not come close to meeting the threshold for violating privacy rights. The heavens are far from falling.

Health-focused psychotherapy offers a contemporary model used in assessment, treatment planning and evaluation in addressing
patients with both medical and psychiatric diagnoses. Clinicians in the health and mental health disciplines must know and
understand the importance of standards of care and models of intervention and evaluation in clinical practice for this type
of patient. Examined is the use of a specific model providing a tailored orientation to patient education, along with the
development and use of a clinical algorithm and care pathway for clinical practice. Provided is a case study for applying
the development and use of a clinical algorithm and care pathway for a dual diagnosed patient receiving health-focused psychotherapy. 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

We evaluated the effects of systematic application and removal of protective equipment on three topographies of self-injurious behavior (SIB) exhibited by a girl who had been diagnosed with autism. Results showed that when protective equipment was applied, SIB decreased to near-zero levels. In addition, withdrawal of protective equipment for specific topographies of SIB (by removing only the corresponding padding) increased rates of SIB only for that topography of SIB. Next, a functional analysis of hand SIB showed that protective equipment suppressed this behavior in all conditions and that the behavior was maintained by automatic reinforcement when padding was removed. Results are discussed in terms of sensory extinction as a possible mechanism responsible for response suppression. 相似文献
