Experimental control flags | |
| #define | FEEDBACK 0 |
| Turn on response feedback (default). | |
| #define | FEEDBACK1 01 |
| Feedback for the first task only. | |
| #define | FEEDBACK2 02 |
| Feedback for the second task only. | |
| #define | FEEDBACK3 03 |
| Feedback for the third task only. | |
| #define | NO_FEEDBACK 04 |
| No feedback. | |
| #define | TWOAFC 0 |
| Experimental response is to Left/Right click using mouse or arrow keys (default). | |
| #define | POINTER 010 |
| Experimental response is to point to some location and Left click. | |
| #define | TIMER 020 |
| Experimental response time is measured from stimulus presentation to Left click. | |
| #define | NO_RESPONSE 030 |
| No response expected, automatically proceeds to the next trial. | |
| #define | CORRECT 0 |
| Allow finger errors to be corrected (default). | |
| #define | NO_CORRECT 0100 |
| Do not allow any error correction. | |
| #define | NO_THRESH 0 |
| No threshold measurement algorithm (default). | |
| #define | PSI 010000 |
| Kontsevich & Tyler adaptive algorithm. | |
| #define | MCS 020000 |
| Method of constant stimuli. | |
| #define | PSI_C 030000 |
| for multiple task paradigms: only trilas with correct previous tasks are counted in the adaptive procedure | |
| #define | PSI_I 040000 |
| the same, but only incorrect previous tasks trials count | |
| #define | SINGLE_TASK 0 |
| a single-task experiment (default) | |
| #define | DUAL_TASK 01000 |
| a dual-task experiment | |
| #define | TRIPLE_TASK 02000 |
| a triple-task experiment | |
| #define | NO_ADAPT 0 |
| no targets for the adaptive algorithm (default) | |
| #define | ADAPT_SETS 1 |
| separate algortithm for each set | |
| #define | ADAPT_CONFIGS 2 |
| separate algorithm for each configuration | |
| #define | ADAPT_SETS_CONFIGS 3 |
| separate algorithm for each set and configuration | |
| #define | ADAPT_LIN 0 |
| use linear steps in the adaptive algorithm | |
| #define | ADAPT_LOG 1 |
| use logarithmic steps in the adaptive algorithm (default) | |
| #define ADAPT_CONFIGS 2 |
A separate instance of the adaptive algorithm will run for each configuration
| #define ADAPT_LIN 0 |
The Kontsevitch & Tyler adaptive algorithm can sample the signal space either linearly (ADAPT_LIN) or logarithmically (ADAPT_LOG). Logarithmic steps are appropriate when the threshold seeked (approximately) obeys the Weber law.
| #define ADAPT_SETS 1 |
A separate instance of the adaptive algorithm will run for each set
| #define ADAPT_SETS_CONFIGS 3 |
A separate instance of the adaptive algorithm will run for each configuration within each set
| #define NO_ADAPT 0 |
No instances of the adaptive algorithm will run
| #define SINGLE_TASK 0 |
PEACH allows up to three simultaneous tasks. Observer has to indicate his/her response to each task by consequitive mouse events. Each task can have it's own adaptive algorithm.
