Posner devised a scheme of using valid and invalid cues across trials. In valid trials, the stimulus is presented in the area as indicated by the cue. For example, if the cue was an arrow pointing to the right, the subsequent stimulus indeed did appear in the box on the right.
Example of a random dot kinetogram as used in a 2AFC task. Monkeys were trained to look at a center stimulus and were then presented with two salient stimuli side by side. A response can then be made in the form of a saccade to the left or to the right stimulus. A juice reward is then administered after each response.
One form of cue that can be implemented in an inhibition of return task are exogenous cues. Exogenous cues are stimuli that are produced in the environment surrounding. Because one's attention is shifted to the stimulus without much thought or effort, these cues are seen as a form of reflex that the person has low control over.
In Posner's cueing paradigm, [4] the task was to detect a target that could be presented in one of two locations and respond as quickly as possible. At the start of each trial, a cue is presented that either indicates the location of the target (valid cue) or indicates the incorrect location thus misdirecting the observer (invalid cue).
Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating. Behavior is a response (R), typically controlled by past consequences and also typically controlled by the presence of a discriminative stimulus. It operates on the environment, that is, it ...
For example, you might not be willing to talk about your weight at all. If that's the case, practice deflecting—"I'm not really interested in talking about myself tonight. Let's focus on you.
It’s more than likely that you won’t run into any major issues when you walk your dog, but it’s easy to reduce this risk further still – and there’s one simple cue that could come in ...
Due to the effect of reward cues and Pavlovian-instrumental transfer on the amplification of incentive salience for rewarding stimuli, PIT is believed to be one of the mechanisms responsible for producing "cue-triggered wanting", or craving, for a drug that occurs when an individual with a drug addiction is exposed to drug cues [note 2] even ...
