In Experiment 1 rats were required to learn a Y-maze in which reward was made available after a given response (e.g. a left turn) regardless of which arm was used as the start-box. Subjects with lesions of the caudate-putamen showed a deficit on this response-learning task compared with control subjects (unoperated animals and rats having lesions of the posterior cortex). In Experiment 2 rats with caudate-putamen lesions were unimpaired when the direction of the turn required to reach the correct goal-box (identified by means of a salient visual intra-maze cue) varied from trial to trial. In the absence of salient intramaze cues, but with enriched room (extra-maze) cues, the rats with caudate-putamen lesions were superior to controls on this task. It is argued that caudate-putamen lesions disrupt a mechanism responsible for processing information about responses, but that the other (spatial) mechanisms responsible for maze-learning remain intact and that caudate-putamen lesions may enhance performance on spatial tasks for which information about responses is irrelevant. 相似文献

Two cases of surface dyslexia are described. In this disorder, irregular words such as broad or steak are less likely to be read aloud correctly than regularly-spelled words like breed or steam; and when irregular words are misread the incorrect response is often a regularisation (reading broad as "brode" and steak as "steek, for example). When reading comprehension was tested, homophones were often confused with each other: for example, soar was understood as an instrument for cutting, and route was understood as being part of a tree. Spelling was also impaired, with the majority of spelling errors being phonologically correct: for example, "search" was spelled surch. "Orthographic" errors in reading aloud (omitting, altering, adding or transposing letters) were also noted. These errors were not due to defects at elementary levels of visual processing.
One of our cases was a developmental dyslexic, and the other was an acquired dyslexic. The close similarity of their reading and spelling performance supports the view that surface dyslexia can cccur both as a developmental and as an acquired dyslexia.
A theoretical interpretation of surface dyslexia within the framework of the logogen model (including a grapheme-phoneme correspondence system for reading non-words) was offered: defects within the input logogen system, and in communication from that system to semantics, were postulated as responsible for most of the symptoms of surface dyslexia. 相似文献

Evidence-based therapeutic and preventive intervention programs (EBIs) have been growing exponentially. Yet EBIs have not been broadly adopted in the United States. In order for our EBI science to significantly reduce disease burden, we need to critically reexamine our scientific conventions and norms. Innovation may be spurred by reexamining the traditional biomedical model for validating, implementing, and diffusing EBI products and science. The model of disruptive innovations suggests that we reengineer EBIs on the basis of their most robust features in order to serve more people in less time and at lower cost. A disruptive innovation provides a simpler and less expensive alternative that meets the essential needs for the majority of consumers and is more accessible, scalable, replicable, and sustainable. Examples of disruptive innovations from other fields include minute clinics embedded in retail chain drug stores, $2 generic eyeglasses, automated teller machines, and telemedicine. Four new research approaches will be required to support disruptive innovations in EBI science: synthesize common elements across EBIs; experiment with new delivery formats (e.g., consumer controlled, self-directed, brief, paraprofessional, coaching, and technology and media strategies); adopt market strategies to promote and diffuse EBI science, knowledge, and products; and adopt continuous quality improvement as a research paradigm for systematically improving EBIs, based on ongoing monitoring data and feedback. EBI science can have more impact if it can better leverage what we know from existing EBIs in order to inspire, engage, inform, and support families and children to adopt and sustain healthy daily routines and lifestyles.
