Dear Jaewon, thank you very much for your reply. Now everything is clearer and we are on the same line with the trigonometric approach. I was wrong in my original argument about the maximum eccentricity of my monitor, firstly because I have always worked with eccentricities within 25-30 degrees. In fact, as you correctly calculated, there is more or less a constant relationship between 1 degby mlanzilo - Questions and Answers
Dear Jaewon, just to update the readers. My assumption comes from the idea that a good approximation to calculate the view distance of the subject from the monitor is by using the trigonometric function as follows: physical distance(s) on the monitor= Viewdistance(d) * tan(alpha in degrees); My advice is to take into account the following paper (https://www.nature.com/articles/s41598-019-572by mlanzilo - Questions and Answers
Dear all, I have a monitor with a resolution of 1920px X 1080 px (121.5 X 68.5 cm). The diagonal size (cm) of the monitor is 139.5 cm. The viewing distance (cm) from the monkey to the monitor is 57 cm. At 57cm of viewing distance, 1 degree should correspond 1 cm. Is it correct? This means that I could present on the monitor stimuli until about 60 degree of eccentricity on the x-axis and about 3by mlanzilo - Questions and Answers
Dear all, until few days ago I was able to use the second monitor very well. All stimuli were presented simultaneously with the experimenter's monitor. Today, this is not the case. I have big delays which do not allow to perform the task on the second monitor. The strange think is that if I select the option "forced use of fallback screen" everything works well.

Dear all, I am building my own task with condition file + timing script v1. I am creating a delayed match-to-sample (DMS) task with the sample stimulus position randomized within the visual field. During the delay phase, I am adding a button whose pressing (meaning: "yes, I saw the sample stimulus") allows to go to the choice phase. Let's assume the subject has a lesion in a smaby mlanzilo - Questions and Answers
Dear all, I am trying to execute mokeylogic on my new window 7 virtual machine. I do not have still installed a DAQ for external input or output control. However, I would like to try to create a new task where I simply show on a secondary screen a stimulus. Then, I tryed to do it but matlab says that toggleobject function is not available. I searched this function within the monkelogic toolboxby mlanzilo - Questions and Answers
