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.
IOR was first described in depth by Michael Posner and Yoav Cohen, [1] who discovered that, contrary to their expectations, reaction times (RT) to detect objects appearing in previously cued locations were initially faster to validly cued location (known as the validity effect), but then after a period of around 300 ms, response times to a previously cued location were longer than to uncued ...
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).
For example in a lexical decision task a participant observes a string of characters and must respond whether the string is a "word" or "non-word". Another example is the random dot kinetogram task, in which a participant must decide whether a group of moving dots are predominately moving "left" or "right".
For example, the law lowered the 15% tax rate to 12%, nearly doubled the standard deductions, simplified the filing process for many taxpayers, and potentially reduced taxable income for middle ...
Hopefully, you won’t need to use the cue too often on your walk, but it’s great to have it in your locker for when it’s required. When walking your dog on a long line, it’s vital that ...
In psychology, contextual cueing refers to a form of visual search facilitation which describe targets appearing in repeated configurations are detected more quickly. The contextual cueing effect is a learning phenomenon where repeated exposure to a specific arrangement of target and distractor items leads to progressively more efficient search.
Examples of cue learning that are not cue recruitment include: Cue weighting . When two or more trusted cues are available to estimate the same property of the world, human perceptual systems usually exhibit data fusion , and it is possible to change the relative weights given to different cues through training (Ernst et al., 2000).
