of stimulus intensity needed for a stimulus to be perceived. In other words‚ the absolute threshold is the amount of intensity needed for a person to detect a difference between something and nothing. Differential thresholds refer to the intensity difference needed between two stimuli before people can perceive that stimuli are different. Thus‚ the differential threshold is a relative concept. Weber’s law (1834) states the positive relation between the first stimulus and the second stimulus. The

The Behavioral Model Abnormal Psychology 212 Abstract The Behavioral Model is based on the concept that behaviorist concentrate on behaviors of individuals and suggest that development occurs in accordance with the principles of learning. The theorists behind this model believe that classical conditioning‚ operant conditioning‚ and modeling all contribute to behavior‚ whether it is normal or abnormal. Treatments used under this model are designed to identify problematic behaviors in patients

These include acquisition‚ extinction‚ spontaneous recovery and generalisation. For classical conditioning to take place‚ it is necessary to have many pairings of the unconditional stimulus (UCS) and the conditional stimulus (CS). The phase when this connection is made and grows stronger is known as acquisition. An example of this can perhaps be seen with spiders. If bitten by a poisonous spider it is certain to elicit feelings of pain and fear. Many
Premium Psychology Behaviorism Learning
Conditioning is a technique used in behavioral training. Classical conditioning is a naturally occurring stimulus paired with a response. A previously neutral stimulus is then paired with the naturally occurring stimulus. Eventually‚ the previously neutral stimulus will come to evoke the response without the presence of the naturally occurring stimulus. The two functions are then become the conditioned stimulus and the conditioned response. The classical conditioning model of behaviorism is based upon the

Exposure therapy is a treatment measure that counteracts the avoidance behaviour that individuals go through when they are fearful of a specific object or situation (American Psychological Association). As avoiding the phobic stimulus may have benefits in the short-term‚ the fear will still be prevalent in future. Therefore‚ exposure therapy is a means of helping the individual have contact with the phobic stimulus in a non-harmful environment. This‚ in turn
