Is it possible to put text over Bitmaps? What I am trying to do is have the buttons and what they symbolize for the task show up on the screen throughout the entire experiment. For my experiment that would mean saying "B is Happy" and "M is Fear" when identifying what emotion the face on the screen is displaying. Personally, I am not super concerned about this, but my professor thinks that people will forget which button is what throughout the task despite the directions before the task stating what to press for what answer.

Perhaps, instead of text, you could create images of the texts. And then you could present the 3 images together. On how to present multiple images in a single trial you may find the info in this link useful www.psytoolkit.org/lessons/select_bitmap.html |

I also tried using the draw on and draw off function and this did not work. I am currently trying to use the draw on and draw off function for a bitmap that contains the text I want to display, but that is not working either. Here is what I have tried for the draw on and off script for the bitmap of the text.
bitmaps
a1501
a1502
a1503
a1504
a1505
a1506
a1507
a1508
a1509
a1510
a1511
a1512
a1513
a1514
a1515
FearandHappy
table happyfearcondition
"f7h3 BM 1501" a1501 1
"f7h3 BM 1502" a1502 1
"f7h3 BM 1503" a1503 1
"f7h3 BM 1504" a1504 1
"f7h3 BM 1505" a1505 1
"f7h3 BM 1506" a1506 1
"f7h3 BM 1507" a1507 1
"f7h3 BM 1508" a1508 1
"f7h3 BM 1509" a1509 1
"f7h3 BM 1510" a1510 1
"f7h3 BM 1511" a1511 1
"f7h3 BM 1512" a1512 1
"f7h3 BM 1513" a1513 1
"f7h3 BM 1514" a1514 1
"f7h3 BM 1515" a1515 1
"fearandhappy" FearandHappy 1
task happyfearcondition
table happyfearcondition
keys b m
draw off
show bitmap FearandHappy 0 200
show bitmap a1501
draw on
readkey 1 1100

On how to present multiple images in a single trial you may find the info in this link useful www.psytoolkit.org/lessons/select_bitmap.htmlThanks for the suggestion! I did try this, but it is not working for me. Could you look at my other comment and see if you see an issue with the way I coded that? |

You can present text stimuli on other stimuli, for example as shown here (instead of bitmap, I show rectangle, but the idea is the same).
task test
keys b
show rectangle 0 0 400 200 255 0 0
show text "Hello there" 0 0 255 255 0
readkey 1 9999
block test
tasklist
test 5
end
Note that the text is on top of the rectangle. The order of the stimuli matters. Each consecutive stimulus is drawn on the preceding ones.
Also note that draw off/on is rarely (if ever) needed and I would recommend to ignore it except for very special circumstances.
If you present stimuli one after another, draw off/on is done automatically. That is, in the example above, show rectangle and show text will be happening exactly at the same time.
