Signal Detection Code

;;;; Title: Signal Detection Task

;;;;

;;;; This task is designed to quantify participant's ability to detect

;;;; and react to ambigous stimuli.

;;;;

;;;; It provides 30 circles and & squares and requests that the participant

;;;; pushes the space bar when they see a circle. The trial data and computed

;;;; measures of d prime, theta, and reaction times are printed in the both

;;;; the experimental and individual participant output file. There is also a

;;;; simple reaction time task placed at the end of this experiment that data

;;;; is also output to the experimental and individual output files. Absent

;;;; reactions are represented with the integer 9999.

;;;;

;;;; To run this code be sure to change the basepath and load it into allegro

;;;; common lisp 6.0 or higher. It will automatically start.

;;;;

;;;; This task is allegro dependent, therefore also bound to a PC.

;;;; unfortunantley this task was written by a novice lisp programmer (myself)

;;;; and this task has not yet been expanded to other listners.

;;;;

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;; IMPORTANT!!!! READ

;; It is very difficult to dynamically display the stimuli to different

;; screen settings, therefore, in order for everything to work smoothly

;; with this experiment please set your screen settings to a 1024 by 768 pixel

;; size setting. Also Set the *basepath* to the directory where you

;; would like the result files to be stored. Also please note that

;; session 2 and only session 2 will result in a complete reversal in the

;; time, location and stimuli.
