This annotated bibliography containing research on visual perception executed at photopic levels in artificial laboratory situations has been compiled to make information available that can be applied to scotopic perception of natural objects in natural situations. There are 407 reports or studies, published from 1945 through 1964, cited in this…

The purpose of this study was to construct a pictorial instrument and evaluate its effectiveness. The instrument, the Blue Version Biology Pictorial Classroom Test (BVBPCT), was composed of multiple-choice items, each of which posed a question or problem about a pictorial. The 404 subjects for the study were randomly assigned to one of four…

From the ideas well set forth by Ferguson, Messick and others, a method was sought that would identify different abilities that entered at different stages in a task. The method selected should meet Cronbach's criterion that it would consider individual differences as well as group performance. Tucker's (1960, 1966) method seemed to be able to…

The purpose of the present study was to investigate more directly the effects of content and repetition of contingent visual feedback on a discrete operant pulling response and accompanying visual attention in 24 six- to seven-month old infants. Simultaneous recording was made of infant operant behavior and visual attention. Results indicated…

This paper discusses some methodological, theoretical and physiological issues to be considered in the use of film tests in research relating to visual cognition and memory. One trouble spot in methodology is the use of a square data matrix with an insufficient number of observations in proportion to variables. A second methodological problem…

Recent theories of verbal memory have hypothesized that memory for a stimulus is not represented by a unitary memory trace, but rather by a coding on several attributes of the event. The present experiment tested the differential forgetting hypothesis in a unique way. Words were presented either visually (V) or auditorally (A) in a continuous…

This paper makes an informational analysis of teachers' verbal discourse. A behavioral analysis is also made in terms of "tacts" and "mands," as defined by Skinner. These behavioral components of a message may be quantified in terms of "originality,""redundancy," and "complexity." But the most…

The relation between type of label and perception of faces was assessed. Sixty-four second and sixth grade Ss were randomly assigned to four experimental conditions in which various kinds of labeling training were associated with four purple and green smiling and frowning faces. Ss then judged the similarity of pairs of the faces. Results revealed…

This brief report summarizes a study to identify primary bound conditions of sound level selection as a first step in collecting base-line data for evaluating selective listening performance in infants with known or suspected hearing loss. Ten normal 9 to 22 month old infants in their home cribs played with an automated operant "toy" that allowed…

The purpose of this study was to determine if stimuli of high potential imagery (pictures) would be less subject to negative transfer than stimuli of lower potential imagery (concrete words). (Editor)

Four experiments are reported which employ a recall-reaction time paradigm. The experiments are designed to establish the baseline effects in the paradigm, determine which of these effects should be attributed to the retrieval stage of processing and investigate the effect of semantic memory in this task.

Briefly discusses what time means to an American Indian. (NQ)

Part of the unique status of picture recognition ability may lie in the procedure used to assess the ability and the great complexity of the stimulus itself. Pictures coupled with the recognition procedure may produce unexpected results, as this article attempted to demonstrate. (Author/RK)

Pictures of common objects apparently function as effective memory representations without evoking their corresponding name codes. The first three experiments of this report were designed to explore the limits of the independence of the naming process by varying relationships between the labels for the pictures and their responses.
