The visual scanning of redundant and random spatial configurations of two-digit numbers was investigated in a target recognition task. The experimental technique involved a brief exposure of a probe (a two-digit number) at the center of the visual field, followed by a spatial pattern of 16 two-digit numbers which included the matching target in…

The spatial layout of visual displays was evaluated by means of three magnitude estimation tasks and one reproduction task. Each stimulus display consisted of 16 randomly-drawn, two-digit numbers. Six different spatial layouts, or display types, were used: systematic vs. random spatial order of numbers; regular vs. irregular boundaries of the…

A study was conducted to examine the ways individuals in organizations interpreted and responded to ambiguous messages. Using Karl Weick's model of organizing, investigators measured the number of rules (criteria for taking action), the number of people, and the frequencies of message categories generated in two simulated organizations comprised…

This paper is a draft for the American Psychological Association Symposium on the conditioning of verbal behavior and attitudes. The author presents the results of several studies he conducted in the classical conditioning of meaning and attitude. These studies attempt to control the measurement effects created by extraneous variables operating on…

Letter-letter, letter-number, and number-letter paired associates were used in this A-B, B-C, A-C study. There were two A-C lists, the positive-transfer stimulus-items of one became the negative-transfer stimulus-items of the other, and vice versa. Twenty subjects were included and each learned one A-C list. The main effects included, among…

Notes that prior assumptions that writing requires phonological mediation has been questioned due to the observation that on tasks requiring the production of spoken and written responses on the same naming attempt, some aphasic subjects produce different words. The data suggest that phonological and orthographic word forms can interact. (53…

Stimulus preference assessments for individuals with developmental disabilities typically involve offering choices among stimuli and providing immediate access to the chosen stimuli. Several researchers have explored the utility of presenting choices verbally, thereby obviating the need to present the choices in tangible form and deliver access to…

Three experiments were conducted to study motor programs used by expert singers to produce short tonal melodies. Each experiment involved a response-priming procedure in which singers prepared to sing a primary melody but on 50% of trials had to switch and sing a different (secondary) melody instead. In Experiment 1, secondary melodies in the same…

The degree of acquaintance among group members (friends or strangers) and the opportunity for group members to observe each other's actions (anonymous or non-anonymous) were manipulated in a 2 x 2 factorial design, to determine the amount of aversive stimulation that would be administered to a target person. When group members could not observe…

Describes observer-based technique for assessing auditory capacities of infants from three to 12 months of age. This technique, referred to as the Observation-based Psychoacoustic Procedure (OPP), combines features of the Forced-choice Preferential Looking Technique and of the Visual Reinforcement Audiometry. Pure-tone detection and frequency…

This study investigated the efficacy of using inoculation theory in developing students' skills in resisting pressures involved with drinking and driving situations. Inoculation theory stems from psychosocial investigations that have demonstrated that resistance to specific opposing arguments can be increased if subjects are familiar with these…

Evaluates the efficacy of two training procedures for eliminating selective stimulus control observed with three trainable mentally retarded children. In another experiment, improvements in stimulus control were not a function of varying degrees of difficulty between stimulus sets or of a prior history of discrimination training with the less…

Examined fourth and fifth graders' reactions to completing group-administered, positive and negative peer nomination techniques. Found that no child reported having hurt feelings or knowing of anyone else having hurt feelings. Determined that the condition of minimal risk of harm, harm not greater than children might encounter in daily life, was…

Reports on three experiments that do the following: 1) investigate the motivational and reinforcing structure underlying male sex role action in a three-person (a female and two males) exchange; and 2) contribute new information on females' interpersonal evaluation of males expressing masculine sex typed and androgynous sex role orientation. (MW)

Examined the effects of perceived control and close alternative outcomes on counterfactual generation (thoughts of what could have been). Subjects played a "wheel of fortune" game in which they controlled one of two wheels. Results supported the idea that people generate counterfactuals about events over which they have perceived…
