Visual objects are often defined by multiple features. Therefore, learning novel objects entails learning feature conjunctions. Visual cortex is organized into distinct anatomical compartments, each of which is devoted to processing a single feature. A prime example are neurons purely selective to color and orientation, respectively. However,…

The role of the "foraging" ("for)" gene, which encodes a cyclic guanosine-3',5'-monophosphate (cGMP)-dependent protein kinase (PKG), in food-search behavior in "Drosophila" has been intensively studied. However, its functions in other complex behaviors have not been well-characterized. Here, we show experimentally in "Drosophila" that the "for"…

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

A battery of memory tests was administered to 243 male university students. Factor analysis with oblique rotation of factors revealed five factors: (1) associative memory (particularly important in paired-associate tests), (2) short-term visual memory (the ability to derive information from briefly presented visual displays), (3) meaningful memory…

This project was concerned with the topic of elaborative activity and learning efficiency. "Elaboration" is regarded as an hypothetical process, internal to the learner, which consists of conceiving an event that can serve as a common semantic referent for elements that are initially disparate. The objective of the project was to examine…

This curriculum is designed primarily for use in individualized classrooms where the teacher is working with an assistant, but it has also been proven effective in traditional classrooms and in remedial situations. Program 1 focuses on the basic abilities children use to analyze and organize graphic and other spatial patterns--skills directly…

CONCEPT FORMATION IN 50 KINDERGARTENERS WAS STUDIED BY REQUIRING THE CHILDREN TO SORT CARDS ACCORDING TO ONE OF FOUR ATTRIBUTES OF THREE DIFFERENT DIMENSIONS. THE OBJECTIVE WAS TO EXPLORE THE VALIDITY AND LIMITATIONS OF AN ALL-OR-NONE LEARNING MODEL FOR COMPLEX CLASSIFYING RESPONSES. INFORMATION WAS PRESENTED TO THE SUBJECT BY TWO POSITIVE…

To assess the importance of visual attributes relative to acoustic and semantic attributes in children's encoding, a 64-item recognition test was administered to first- and sixth-grade children. Recognition items were linedrawings of simple objects accompanied by aural labels. By manipulating the picture, label, and referent in various…

Nonverbal context is important in the language acquisition process. The present study compares different amounts and ordering of pictorial context with respect to their effect on learning word-referent relations in a second language. Twenty-five monolingual English-speaking high school students were shown twenty Spanish sentences and pictures of…
