Study based on M.A. Thesis submitted to Memphis State University (Meador, 1967).

Based on PhD dissertation submitted to the University of California, Los Angeles.

This study investigates a negative component (N220) of visual evoked potential (VEP) which increases as certain cognitive processes are activated. Nine experimental conditions were designed by combining three stimulus and three task conditions. Letters were used as verbal stimuli, matrix patterns were used as nonverbal stimuli, and white light was…

Subliminal stimulation is defined as that which is perceived by an individual below the threshold of awareness or cognizance. This article traces the history of research in subliminal stimulation to illustrate that under certain circumstances and conditions, this behavioral phenomenon does occur. Although subliminal stimuli do affect human…

Naval researchers studied the effects of delay in the presentatio of visual information on pilot performance. Simulated carrier landing tasks were performed by subjects using a visual display generated by a computer. In one part of the experiment pilots were asked to "fly" carrier approaches with and without a 0.1 second delay in the…

Four experiments were conducted to investigate the extent to which infants of different ages respond to facelike drawings on the basis of stimulus complexity and/or resemblance to the human face. Infants' responses to stimulus patterns were assessed using the corneal reflection technique developed by Robert Trantz. In the first two experiments,…

A total of 14 infants participated in this study of the recovery of visual orienting by crossmodal stimulation when no new visual information was present. The locus of the crossmodal stimulation (auditory stimulation) was discriminable to the subject. Infants in three age groups were tested on three occasions each separated by 30 days. No…

This paper introduces and gives a report of the first of a series of studies concerned with the developmental aspects of information processing. The experiments are concerned chiefly with how repeated visual encounters influence infants' attentional preference for what is familiar or unfamiliar and how infants' preference can be affected by…

Habituation and dishabituation to a simple geometric stimulus were examined for a sample of 36 5-month old subjects. All subjects viewed successive presentations of a standard stimulus, and, following a retention interval, a single presentation of the standard and a novel stimulus in the test phase. During the interpolated interval, repeated…

This study was designed to ascertain the nature of information storage in humans and to determine the channel capacity of Ss at various stages of development. A 3 x 2 x 2 multivariate complete factorial design was employed: the three levels of the first factor (Age) were 5, 8, and 12 years; the two levels of the second factor were Visual and…

The results of two matching-to-sample experiments using color cues in Consonant Vowel Consonant (CVC) stimulus words with kindergarten through third grade subjects are included in this document. Color cues influenced subjects to match according to first letters. When the first letter of each stimulus word was underlined in red, kindergarten and…

The relationship between visual stimulus intensity and directional finger movements was examined in infants of two age groups (16 infants, 10 to 15 weeks old, and 8 infants, 20 to 25 weeks old). Two hypotheses derived from Schneirla's Approach-Withdrawal Theory were examined: (1) that responses of the younger, but not of the older infants, would…

Analyzed was the performance of 30 children with normal reading and speech skills on various blending tasks. There were three groups of ten Ss each with each group receiving one of three modes of presentation: auditory, visual, or auditory visual. The stimuli consisted of 150 consonant-vowel (CV), vowel-consonant (VC), and…

Elementary school students and adults were presented with a paired comparison task of visual complexity in which contour and presence or absence of structure in the patterns were manipulated. Results indicated that complexity judgments of all subjects were affected by the presence of structure at lower levels of contour. (GO)
