The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of ...
Dr. Sidman’s publications in peer-refereed journals number close to 100 and have defined much of our current understanding of stimulus control, stimulus equivalence, and avoidance behavior. His 1960 text, Tactics of Scientific Research, is considered the first primer on within- subject research methodology.
The goal of response prompting is to transfer stimulus control from the prompt to the desired discriminative stimulus. [1] Several response prompting procedures are commonly used in special education research: (a) system of least prompts, (b) most to least prompting, (c) progressive and constant time delay, and (d) simultaneous prompting.
[47] [51] When the response to a target stimulus is sufficiently practiced, the response can be prepared to a degree where only a single critical stimulus feature is needed to specify and elicit the response. Response elicitation by the prime occurs quickly and directly without the need for a conscious representation of the stimulus.
The second stimulus should occur before the complete decay of residual excitation from the first stimulus, which is also referred to as temporal proximity. [9] [13] In other words, the remaining arousal felt from the initial stimulus needs to be present to some degree when the individual is exposed to the second stimulus. [1] [13]
Mean RT for college-age individuals is about 160 milliseconds to detect an auditory stimulus, and approximately 190 milliseconds to detect visual stimulus. [ 29 ] [ 43 ] The mean RTs for sprinters at the Beijing Olympics were 166 ms for males and 169 ms for females, but in one out of 1,000 starts they can achieve 109 ms and 121 ms, respectively ...
Priming is a concept in psychology to describe how exposure to one stimulus may influence a response to a subsequent stimulus, without conscious guidance or intention. [1] [2] [3] The priming effect is the positive or negative effect of a rapidly presented stimulus (priming stimulus) on the processing of a second stimulus (target stimulus) that appears shortly after.
Stimulus onset asynchrony, the time that lapses between the presentations of the two stimuli, acts as the independent variable in this paradigm, and the reaction time to the second stimulus acts as the dependent variable.
