What is flanker task measure?
In cognitive psychology, the Eriksen flanker task is a set of response inhibition tests used to assess the ability to suppress responses that are inappropriate in a particular context.
What is the flanker in the flanker task?
The flanker task (Eriksen & Eriksen, 1974) requires (spatial) selective attention and executive control. In this task, irrelevant stimuli have to be inhibited in order to respond to a relevant target stimulus. The Stroop task (Stroop, 1938) requires selective attention and inhibition control.
What is the flanker compatibility task?
In the flanker compatibility task, they found that action video game players were more easily able to ignore distracting information, suggesting that such players have a greater attentional capacity.
What is the Gratton effect?
The Gratton effect (Gratton et al., 1992) refers to the finding that congruency effects (i.e., Stroop and flanker effects) are reduced following incongruent trials compared to congruent trials.
How is flanker effect calculated?
We calculated two interference scores for the Flanker task: (1) subtracting the mean RT for the correct congruent items from the mean RT for the correct incongruent items within the combination condition and (2) subtracting the mean accuracy for the congruent items from the mean accuracy for the incongruent items …
What means flanker?
Definition of flanker
: a football player stationed wide of the formation slightly behind the line of scrimmage as a pass receiver.
How long does flanker task last?
The setup for the Flanker task is straightforward. In each trial, the stimulus is shown for unlimited time until the participant responds to advance to the next trial. Stimuli in Flanker tasks are typically composed of a target image in the center which is flanked by one or more distractor stimuli on either side.
What is an inhibitory response?
An inhibitory response is a brain function that allows us to stop (or inhibit) an automatic response or action. In other words, it is an ability to suppress inappropriate, irrelevant, or suboptimal actions.
What is a visual search task?
Visual search is a goal oriented activity that occurs regularly in daily life and involves the active scanning of the environment in order to locate a particular target among irrelevant non-targets, or distractors.
What are incongruent trials?
A congruent trial is one in which the flank- ers are associated with the same response as the tar- get (e.g., ), whereas in an incongruent trial, the flankers are associated with a competing response (e.g., ). Reaction times (RTs) are faster for con- gruent than for incongruent trials.
What is an incongruent condition?
Incongruent stimuli are those in which ink color and word differ.
What do the terms congruent and incongruent mean in terms of the Stroop effect?
Congruent stimuli are color-words that are written in the same ink color as the word (i.e., “blue” written in blue ink), whereas incongruent stimuli are those that are written in an ink color that does not match the color-word (i.e., “blue” written in red ink).
How do you do the Stroop test?
Interactive Stroop Effect Experiment
In this experiment you are required to say the color of the word, not what the word says. For example, for the word, RED, you should say “Blue.” As soon as the words appear on your screen, read the list as fast as you can. When you have finished, click on the “Finish” button.
What does the Stroop task demonstrate?
The Stroop test can be used to measure a person’s selective attention capacity and skills, processing speed, and alongside other tests to evaluate overall executive processing abilities.
What does the Stroop effect Tell us about attentional processes?
The Stroop effect refers to our tendency to experience difficulty (conflict or interference) naming a physical colour (we use the term ‘hue’) when it is used to spell the name of a different colour (the incongruity effect), but not when we simply read out colour words (Stroop, 1935).
What does the Simon task measure?
The Simon Task is a behavioral measure of interference/conflict resolution. In this task participants are asked to respond to visual stimuli by making a rightward response to one stimulus (e.g., a circle) and a leftward response to another (e.g., a square).
What does the Simon effect test?
The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides.
Why is the Simon effect important?
In the real world, the Simon effect has important implications. Primarily, it shows that location information cannot be ignored and will affect decision making, even if the user knows that the information is irrelevant.
How do you calculate Simon effect?
The Simon effect was calculated by subtracting the congruent mean reaction times from the incongruent mean reaction times for each condition and day respectively.
What part of attention is involved in the Simon effect?
It has been claimed that spatial attention plays a decisive role in the effect of irrelevant spatial stimulus-response correspondence (i.e., the Simon effect), especially the way the attentional focus is moved onto the stimulus (lateral shifting rather than zooming).
How do you get Simon task on Psychopy?
So the interesting thing that we can do is that we can present an X which is associated with a right key press on the left hand side of the screen.
What is the compatibility effect?
It occurs when there is a harmonious relation between what you observe and how you have to respond to it. The figure below shows a daily life example of a compatible and incompatible situation. If you are right handed, a cup handle on the right side of a cup is compatible.
How is compatibility defined for displays and controls?
Control/display compatibility here refers to the compatibility between the direction of the control and the display, such that a control movement in a given direction results in a parallel movement of the display indicator.
What is movement compatibility?
Movement Compatibility – relationships between movements of displays and controls where the direction of movement of a control follows from expectations, e.g. steering wheel turns car in direction of wheel movement. Movement of a control can: (1) follow – display movement as in radar tracking.
