The author examined the transfer of stimulus control from instructor assistance to verbal cues and pictorial cues. The intent was to determine whether it is easier to transfer stimulus control to one form of cue or the other. No studies have conducted such comparisons to date; however, literature exists to suggest that visual cues may be…

Translation accounts have argued that the presence of a Stroop effect in the context of a nonvocal untranslated response is caused by verbal mediation. In its simplest form, color-labeled buttons are translated into a verbal code that interferes with color responses. On this logic, in the reverse Stroop task (identify the word; ignore the color),…

Reports on three experiments involving 300 six-year old children that investigated the conditions under which young children would produce "separates" as opposed to partial occlusion drawings. (HOD)

THIS STUDY INVOLVED THE IDENTIFICATION OF (1) RELATIONSHIPS BETWEEN REINFORCEMENT AND PHYSICAL COMPONENTS OF COMPLEX PICTORIAL STIMULI IN DISCRIMINATION LEARNING AND (2) VARIABLES RELATED TO PRIOR EXPERIENCE WITH PICTORIAL STIMULI USED IN DISCRIMINATION LEARNING. LINE SHAPES WERE USED AS STIMULI. THESE SHAPES WERE VARIED BY ADDING SOME LINES THAT…

The experiment employed Sternberg's procedure to investigate the effects of presentation and test modalities (auditory or visual), and number of presentations on the processing rate of monosyllabic words of varying graphemic and phonemic length. Twenty college students and 20 sixth graders served as Ss. Each S received all conditions and lists in…

To test the theory that retardates are particularly slow in forming some visual habits, especially attention, a series of experiments were performed using a laboratory device which forced subjects to discriminate between color and form in exchange for an incentive reward. Stochastic models were applied to tests of lower level retardates which…

Results showed that instructions significantly increased recognition accuracy. (Author/MB)

Research conducted over the past 80 years is examined to answer three questions on sensory modality as it relates to reading. In the 18 studies reviewed which relate to the superiority of one modality over another, there was no consensus regarding the relative effectiveness of modalities among adults. The evidence leans toward greater…

Group and single viewers were studied; results showed that group viewers exhibited a large number and variety of verbal and nonverbal, targeted and (probably) nontargeted modeling behaviors; single viewers much fewer.'' (Author)

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

A procedural task was demonstrated via videotape in two formats - one with motion, one using a series of still photographs. The sound tracks were identical. In two experiments the motion treatment was superior for some subjects and cuing arrows made no difference. (Author)

Six- and nine-month-old infants were exposed to contingent or non-contingent perceptual stimulation from a source which was spatially displaced at 60 from the infant's midline. Reliable operant acquisition was observed in the case of the nine-month-old infants, but not in the case of the six-month-old infants whose performance was similar to that…
