Two experiments examined whether postsample signals of reinforcer probability or magnitude affected the accuracy of delayed matching to sample in pigeons. On each trial, red or green choice responses that matched red or green stimuli seen shortly before a variable retention interval were reinforced with wheat access. In Experiment 1, the…

Two experiments with pigeons examined the effects of unsignaled, nonresetting delays of reinforcement on responding maintained by different reinforcement rates. In Experiment 1, 3-s unsignaled delays were introduced into each component of a multiple variable-interval (VI) 15-s VI 90-s VI 540-s schedule. When considered as a proportion of the…

The Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) is designed to provide detailed information on children's development, health, and early learning experiences in the years leading up to entry into school. The ECLS-B is the first nationally representative study within the United States to directly assess children's early mental and…

This study compared children's off-task behavior and physiological response in a normal elementary classroom setting with those in a prescribed classroom environment. In the prescribed environment, the colors of the classroom walls were changed from brown and off-white to blue, while Duro-test Vita-lite fluorescent tubes without diffusers replaced…

From prehistoric times people have been fascinated with color; from cave paintings to the latest computers, color has been a constant companion. Textiles are made more beautiful by the alteration or application of colorants. This teaching resource investigates vat dyes, a colorant class which includes the oldest dyes known as well as important…

A survey of several hundred German students led to two theses on school environment and learning. First, students find school buildings attractive only if they conform to certain features of the human sensory system such as balance. Second, students consider school buildings attractive and inviting only if their architectural message meets such…

Evolving from concern for the increasing requirements for literacy, especially visual literacy, the purpose of this study was to determine the impact of color on learning. Sixty midwestern college students were assigned to groups where they read and studied a graphic presentation, and then were tested on their recall and retention. The following…

For 15 years an ongoing research project at the University of Pittsburgh has focused on the effects of variations in visual complexity and color on the storage and retrieval of visual information by learners. Research has shown that visual materials facilitate instruction, but has not fully delineated the interactions of visual complexity and…

An approach which is designed to help students better understand the utility of models in understanding and doing physics, specifically in a course in light and color, is described in this paper. Explanations are given and illustrations are provided of an analogue model of waves which assist in the creation of an abstract model to deduce Snell's…

This compilation of guidelines for using and producing various forms of media begins with hints for bulletin boards and other displays, including principles of layout, elements of design, and use of color. Advantages and disadvantages of using overhead transparencies are then outlined. Recommended uses of transparencies are listed, and tips for…

A number of variables may affect the ability of students to perceive, and learn from, instructional materials. The objectives of the study presented here were to determine the projected color that provided the best visual acuity for the viewer, and the necessary minimum exposure time for achieving maximum visual acuity. Fifty…

Analyzes the argument, style and structure of the novel, asserting that when analyzed as a poetic novel, the disparate elements and illusive meanings of the book coalesce into an integral whole and provide a poignant insight in to the dilemma of the modern black artist. (Author/JM)

The article discusses outdoor drawing, giving a brief history and its applications in today's classrooms. The use of grids to help students gain an eye for proportions and spatial relationships is emphasized. (KM)

Directions for making and coloring nine paper dolls representing various regions of Mexico are given. These dolls represent the regions of Oaxaca, Veracruz, Hildalgo, Yucatan, Potosina, Puebla, and Chiapas. Each doll is dressed in the traditional costume of the region. (NQ)

The study reported here examined the use of color terms by 36 male and female students in kindergarten through fifth grade in a suburban New York City school. The children were asked to label colors using the fanciest color term they could. The only significant difference found was between younger females and older females, tentatively indicating…
