Sentence Picture Verification Paradigm
Required Experiment Builder Version: 1.4.402 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Easy
This example illustrates:
This example is implemented based on Experiment 1 described in the following paper:
In each trial, a sentence appears at the left side of the screen. Ten degrees to the right of the beginning of the sentence a picture is shown. If the meaning of the sentence matches the spatial position of the star and the plus shown in the picture, a key should be pressed. If not, another key should be pressed (see the instruction screen of the project). The response should be given as quickly and correctly as possible.
One of three possible response types ('correct response', 'incorrect response', and 'no response') is recorded in the 'Response_Type' column of the RESULT_FILE.txt. Also recorded in it is the response latency. If the response is correct, the latency value is shown on the screen as feedback. For the incorrect response, a text string indicating so is shown on the screen and the latency value is recorded as zero. This is also true of the case where no response is given (timeout), but the latency value is recorded as -1 and that of the pressed key as a dot [.].
**Additional detailed information about the project is given in the notes section for most nodes. To see notes for a given node, either mouse over that node or click on it to display the notes window. If the notes window is not visible, go to the "View" drop down menu in Experiment Builder, select "Properties", and check "Note".
