The focus in this article is on the usefulness of spatial sequencing as a tactic for interpreting a map and organizing our memory of it. This skill is useful whenever some condition varies in a systematic way with distance. When students are asked whether they see a pattern on a map of a topic like wildfires or terrorist activity, some students…

Many models of recognition are derived from models originally applied to perception tasks, which assume that decisions from trial to trial are independent. While the independence assumption is violated for many perception tasks, we present the results of several experiments intended to relate memory and perception by exploring sequential…

An extraordinary variety of experimental (e.g., flicker, magnetic fields) and clinical (epilepsy, migraine) conditions give rise to a surprisingly common set of elementary hallucinations, including spots, geometric patterns, and jagged lines, some of which also have color, depth, motion, and texture. Many of these simple hallucinations fall into a…

The study examined the perception of random lines by people with gambling problems compared to people without gambling problems. The sample consisted of 67 probable pathological gamblers and 46 people without gambling problems. Participants completed a number of questionnaires about their gambling and were then presented with a series of random…

Feedback is a crucial form of information for learners. With the availability of new educational technologies, the manner in which feedback is delivered has changed tremendously. Existing research on the learning outcomes of the content and nature of computer mediated feedback is limited and contradictory. "Signals" is an educational data-mining…

In 6 experiments, the authors investigated the form of serial position functions for identification of letters, digits, and symbols presented in strings. The results replicated findings obtained with the target search paradigm, showing an interaction between the effects of serial position and type of stimulus, with symbols generating a distinct…

The primary purpose of this study is to determine how students are impacted by the use of Classroom Response System (CRS) technology. This research explores the nature of the outcomes experienced by students and their perceptions on the leading pedagogy and practices for using CRS technology in the classroom. The research is both quantitative and…

Learning in educational settings emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other crucial components of learning, especially improvements produced by experience in the extraction of information: perceptual learning (PL). We suggest that such improvements characterize both simple sensory and complex…

Explores how a dyadic understanding of perception cancels the validity it might have as a model for the linguistic process. Discusses commonly misunderstood exhibits in the gallery of perception studies--the duck-rabbit and Magritte's pipe. (RS)

Investigates the ability of four-, seven-, and ten-month-old infants to perceive and base novelty responses on correlations among perceptual attributes in a category-like context. In a habituation-dishabituation paradigm, ten-month-old infants clearly responded on the basis of the correlation among attributes, while four- and seven-month-old…

All mathematical feature selection techniques can be classified into one of two major categories--feature selection in the measurement space and feature selection in the transformed space. This article discusses the various feature selection techniques in the light of this two-category classification. (Author/HB)

Compares one study in which 5-year-olds and another in which adults quantified random patterns of dots under unlimited exposure duration. Data on operating ranges and rates for subitizing and counting are included. (JMB)

Presented is experimental evidence that humans develop strong preferences for objects that become familiar through repeated exposure, even when the exposures are so degraded that they cannot be discriminated as stimuli previously seen. Implications are made regarding other studies where affective discriminations are made with very little stimulus…
