TL;DR: The spatial query and spatial reasoning based on a 2D C-string representation are presented and the similarity measure is defined and the algorithm for similarity retrieval of iconic images is also proposed.

TL;DR: The results indicate that aspects of conceptual knowledge are encoded in multimodal and higher level unimodal areas involved in processing the corresponding types of information during perception and action, in agreement with embodied theories of semantics.
Abstract: Recent research indicates that sensory and motor cortical areas play a significant role in the neural representation of concepts. However, little is known about the overall architecture of this representational system, including the role played by higher level areas that integrate different types of sensory and motor information. The present study addressed this issue by investigating the simultaneous contributions of multiple sensory-motor modalities to semantic word processing. With a multivariate fMRI design, we examined activation associated with 5 sensory-motor attributes--color, shape, visual motion, sound, and manipulation--for 900 words. Regions responsive to each attribute were identified using independent ratings of the attributes' relevance to the meaning of each word. The results indicate that these aspects of conceptual knowledge are encoded in multimodal and higher level unimodal areas involved in processing the corresponding types of information during perception and action, in agreement with embodied theories of semantics. They also reveal a hierarchical system of abstracted sensory-motor representations incorporating a major division between object interaction and object perception processes.

TL;DR: In this article, the authors examined trends in the representation of minorities in special education classes since 1978, and found that underrepresentation in classes for the gifted and talented continues to be a problem for blacks, Hispanics, and American Indians.
Abstract: This article examines trends in the representation of minorities in special education classes since 1978. An analysis was done of the four most recent Office of Civil Rights Surveys of elementary and secondary schools regarding student enrollment and placement, published between 1980 and 1986. Data from the surveys suggest a decline of overrepresentation in some areas such as Hispanics in classes for educable mentally retarded students, but a continued overrepresentation of blacks in classes for educable mentally retarded, trainable mentally retarded, and seriously emotionally disturbed students. Underrepresentation in classes for the gifted and talented continues to be a problem for blacks, Hispanics, and American Indians.
