Developmental Impacts of Sensory Deprivation Neural development (e.g., brain structure and function abnormalities) Neurogenesis (e.g., reduced production of new neurons) “Poverty of stimulus” is a condition in which an individual is exposed to a limited range or quantity of sensory input. This can lead to significant developmental deficits and cognitive impairments, as the brain is…

Stimulus Class ABA In ABA therapy, a stimulus class refers to a group of stimuli that evoke similar behavioral responses due to shared physical or functional attributes. Defining stimulus control involves identifying the critical features that distinguish between different classes and establishing associations between specific stimuli and desired behaviors. Through techniques like discrete trial training,…

A stimulus class refers to a group of stimuli that evoke similar responses despite having different physical characteristics. Members of a stimulus class share relevant features, and when one member is associated with a particular response, generalization occurs, leading to similar responses to other members of the class. Stimulus generalization involves responding to novel stimuli…

Method of Constant Stimuli: A psychophysical research method that involves presenting stimuli at constant values, allowing participants to report their perceived intensity or quality. Core Entities: Statistical analysis, sensory concepts, experimental design. Additional Entities: Applications in sensory evaluation, consumer research. Excluded Entities: Just noticeable difference, adaptive methods, threshold estimation. The Core Elements That Make the…

Distal vs Proximal Stimulus A distal stimulus is a stimulus that originates outside the body, while a proximal stimulus is a stimulus that originates within the body. Sensory receptors detect distal stimuli and convert them into electrical signals. These signals are then transmitted to the central nervous system by afferent neurons. The central nervous system…

Transfer stimulus control involves shifting the response to a new stimulus while gradually fading out the original one. This technique is frequently employed in behavior therapy to address various concerns such as anxiety, phobias, and addictions. By replacing the triggering stimulus with a different cue, individuals can learn to elicit the new, desired response, promoting…

Stimulus equivalence aba refers to a procedure in behavior analysis where three stimuli (A, B, and C) are presented in a series of trials. In each trial, one stimulus is presented as the sample, and the participant is required to choose the comparison stimulus that is equivalent to the sample. Repeated trials establish equivalence classes…

Derived stimulus relations are learned connections between a neutral stimulus and a reinforcer or punisher through pairing. These relations allow individuals to respond to previously neutral stimuli as if they possessed the properties of the reinforcer or punisher. They are based on classical conditioning principles and involve the cognitive processes of perception, attention, and memory….

Stimulus stimulus pairing in classical conditioning refers to the association between a neutral stimulus (CS) and a stimulus that naturally elicits a response (UCS). Through repeated pairing, the CS gains the ability to elicit a similar response (CR) as the UCS. This process, first observed by Pavlov in his dog experiments, involves the gradual strengthening…

Paired stimulus preference assessment is a behavioral assessment technique that compares an individual’s preference between two stimuli. The assessment involves presenting the individual with two options and observing their choice. This technique is used to determine the individual’s preferences for different activities, foods, or objects, and can be used to make decisions about interventions or…

Stimulus discrimination refers to an organism’s ability to distinguish between different stimuli and respond appropriately. It involves learning to associate specific stimuli with distinct consequences, allowing the organism to adapt its behavior based on environmental cues. This process is crucial for survival and enables animals to navigate complex environments by making informed decisions about approaching…

Transfer of Stimulus Control Transfer of stimulus control refers to the process wherein a previously neutral stimulus becomes effective in eliciting a response that was originally associated with a different stimulus. This occurs when the neutral stimulus is repeatedly paired with the original stimulus, leading to the formation of a new association between the neutral…
