Although traditional methods to collect similarity data (for multidimensional scaling [MDS]) are robust, they share a key shortcoming. Specifically, the possible pairwise comparisons in any set of objects grow rapidly as a function of set size. This leads to lengthy experimental protocols, or procedures that involve scaling stimulus subsets. We…

In this study, metacognition refers to performing visual analysis and discrimination of real life events and situations in naïve psychology, naïve physics, and naïve biology domains. It is used, along with measuring reaction time, to examine differences in the ability of four groups of students to select appropriate pictures that correspond with…

Six tree shrews and 8 rats were tested for their ability to infer transitively in a spatial discrimination task. The apparatus was a semicircular radial-arm maze with 8 arms labeled A through H. In Experiment 1, the animals were first trained in sequence on 4 discriminations to enter 1 of the paired adjacent arms, AB, BC, CD, and DE, with right…

E-learning has acquired a prime place in many discussions recently. A number of research efforts around the world are trying to enhance education and training through improving e-learning facilities. This paper briefly explains one such attempt aimed at designing a system to support video clips in e-learning and explains how profiles of the…

Two experiments were conducted to understand the processes through which 5th graders discriminate relevant from irrelevant information when solving mathematical story problems. Visual scanning was recorded and coded as directed toward relevant information, irrelevant information, the question, workspace, and elsewhere. Experiment 1 focused on the…

High state-anxious subjects solved fewer problems than middle or low state-anxious subjects under no memory-aid conditions, and all anxiety groups performed comparably with memory aids. High state-anxious subjects tended to use less focusing strategy when memory aids were unavailable. (Author/CP)

This article focuses on the mechanisms of the human brain whose function is vision. (SA)

Discussion of how to teach students to use different environments for learning focuses on visual awareness and visual problem solving skills in a visual literacy walk. Highlights include observation techniques, multiple perspectives, categorizing and analyzing visual information, and generating multiple solutions for problem solving tasks. (six…

Techniques that teachers can use to help art students to make an educated guess or to estimate an approximate solution while solving a visual problem that has no single correct answer are discussed. (RM)
