According to the language of thought (LOT) approach and the related computational theory of mind (CTM), thinking is the processing
of symbols in an inner mental language that is distinct from any public language. Herein, I explore a deep problem at the
heart of the LOT/CTM program—it has yet to provide a plausible conception of a mental symbol. 相似文献

This is the first of two articles in which we describe how infants adapt their spontaneous leg movements to changes in posture or to elicitation of behaviors by a mechanical treadmill. In this article, we compare the kinematics of kicks produced by 3-month-old infants in three postures, supine, angled (45 degrees ), and vertical, and examine the changes in muscular and nonmuscular force contributions to limb trajectory. By manipulating posture we were able to assess the sensitivity of the nascent motor system to changes in the gravitational context. The postural manipulation elicited a distinct behavioral and dynamic effect. In the more upright postures, gravitational resistance to motion at the hip was 4 to 10 times greater than resistance met in the supine posture, necessitating larger muscle torques to drive hip flexion. Kicks produced in the vertical posture showed a reduction in hip joint range of motion and an increase in synchronous joint flexion and extension at the hip and knee. At the same time, hip and knee muscle torques were also more highly correlated in kicks performed in the vertical than in the supine or angled posture. This increased correlation between muscle torques at the hip and knee implicates anatomical and energetic constraints-the intrinsic limb dynamics-in creating coordinated limb behavior out of nonspecific muscle activations. 相似文献

Complexities abound in the identification and management of families at increased risk for inherited forms of cancer. One of the ways to learn as a profession how best to provide cancer risk counseling (CRC) is to share counseling experiences. Such cases can provide insight into the issues raised by families and ways in which genetic counselors have handled complex situations. Here we describe three CRC cases initially presented at the 1995 American College of Medical Genetics meeting. The first case involves balancing the importance of informing a family of the presence of an inherited cancer syndrome with the family's right not to know. The second case illustrates the difficulties in assisting an individual to make medical management decisions in the face of uncertain risk information. The third case describes the complex interactions with a woman before and after her decision to have prophylactic surgery.

Fifty-six of 80 (70%) full members of the National Society of Genetic Counselors with interest in cancer genetics responded to a 1994 survey regarding their cancer risk counseling practices. This study was undertaken to describe cancer risk counselors and the services they provide and to identify possible differences from general genetic counseling that warrant further study. Of 56 respondents, 41 (75%) were providing CRC. The components of CRC programs are described. Our results found significant differences between CRC and general genetic counseling in terms of training and experience of genetic counselors providing CRC and length and number of counseling sessions per consultand. 51% of respondents had 1–2 years of working in CRC, compared to 17% with 1–2 years experience in genetic counseling (p<0.05). Over one-third had 10 or more years genetic counseling experience. Counselors were more likely to see individuals at risk for cancer for longer counseling sessions (p<0.05) and for additional sessions (p<0.05). 相似文献

High costs of traditional residential treatment forces extensions of the philosophy. "Therapeutic families" is a reworking of the foster family concept. Being part of a network of treatment services, and an extension of the residential treatment center, it makes for shorter stays in the more intensive treatment facility. The philosophical concept and clinical plan are presented. 相似文献

We report two experiments that investigate the effect of an induced mood on the incidental learning of emotionally toned words. Subjects were put in a happy or sad mood by means of a suggestion technique and rated the emotional valence of a list of words. Later on, they were asked to recall the words in a neutral mood. For words with a strong emotional valence, mood-congruent learning was observed: strongly unpleasant words were recalled better by sad subjects and strongly pleasant words were recalled better by happy subjects. The reverse was true for slightly toned words: here, mood-incongruent learning was observed. Both effects are predicted by a two component processing model that specifies the effect of the mood on the cognitive processes during learning. Further evidence for the model is given by rating times measured in Experiment 2. 相似文献
