Proponents of a self-identified "relativist" view of cross-language color naming have confounded two questions: (1) Is color naming largely subject to local linguistic convention? and (2) Are cross-language color naming differences reflected in comparable differences in color cognition by their speakers? The "relativist"…

An attempt is made to provide chemistry teachers with a chemical demonstration of a clock reaction for the winter holiday season that changes in color from green to red to green again which is used as didactic tool to introduce students to many of the basic principles of kinetics. The reaction involves the oxidation of iodide ion with persulfate…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…

The goal-directed theory of imitation (GOADI) states that copying of action outcomes (e.g., turning a light switch) takes priority over imitation of the means by which those outcomes are achieved (e.g., choice of effector or grip). The object [fewer than] effector [fewer than] grip error pattern in the pen-and-cups task provides strong support for…

Clock reactions based upon competing oxidation and reduction reactions of iodine and starch as the most popular type of chemistry example is presented to illustrate the redox phenomena, reaction kinetics, and principles of chemical titration. The examination of the photophysical principles underlying the iodine fluorescence quenching clock…

For mental health professionals, art assessment is a useful tool for patient evaluation and diagnosis. Consideration of various color-related elements is important in art assessment. This correlational study introduces the concept of variety of color as a new color-related element of an artwork. This term represents a comprehensive use of color,…

Education is an active process in which instructors apply various devices to make the material to be taught more suitable for students' perception. As the capabilities of available devices improve, so should the methods of teaching make the best use of them. No tool can ever replace an instructor, but tools can enhance the efficiency of…

This study explored 3- and 4-year-old children's development of scientific vocabulary from participation in repeated interactive read-aloud events and retellings of three informational picture books about light and color, followed by hands-on science activities. Thirty-two children attending a YWCA preschool were matched by age and general…
