From ahay at beeb.net Fri Aug 16 08:07:20 2002 From: ahay at beeb.net (Anthony Haywood) Date: Fri, 16 Aug 2002 08:07:20 +0000 Subject: Please help with my paradigm Message-ID: Dear all, As a new member of this forum, I am not entirely sure that I am posting this in the right place but, here goes... I am writing a paradigm to present the Mackworth clock task to a number of subjects. The paradigm itself consists of a circle of 59 grey dots and one white dot. The white dot moves around the circle, clockwise, as the second had on a clock would do, moving once per second. The task is designed upon 60 pictures which are shown in sequence, ie picture one is the white dot at 0, I then rotated the picture 6 degrees and saved this as picture 2 and so on. What I need to do is present the pictures in sequence but I want to radomly 'skip' one number so on occasion the 'second-hand' skips a notch anbd moves 12 degrees. I am unsure how to do this and any help would be greatly appreciated. Many thanks in anticipation.

From 1 to 60. Then you can write a small code to generate a random number between 1 to 60. And then, you write in the code: if this number is the value of one of the "No" attributes of the pictures, then skip this member of the list. I think there must be a code to generate random number, but i am not sure for the second part; how to make the skip.

And is it possible to subset the sentence using alternate symbols (not slashes) in order to mark a critical region? Any input will help!

It would involve encasing certain statements in "if...then" statements -- you could count the number of words in each set, then when the number of items exceeds the count, you could terminate. And using different delimiters would involve changing the "Phrase = Item$" statements such that the last argument (currently "/") became whatever delimiting character you wanted to use. I'd also suggest, however, that you look at the two moving window paradigm examples that we have up on the STEP site. The first uses a table to store words (instead of using slash-delimited text), and the sentences are of variable length (with arrows in the blanks). In the second, all the sentences are the same length, but certain positions have words that vary.

Basically I have responses from my switch of 1,2 and is recognised in e-prime as such. Problem is I don't know how to get e-prime to accept the response from my serial switches and move on to the next stimulus. I thought about leaving everything as it was (with the keyboard still set as the input device) and fooling the program by setting whatever value is given by the switches (1 or 2) as that given by the keyboard. I don't know if this is a decent way of doing it, but if it is reasonable, how do I go about 'fooling' or more accurately 'manually emulating' the keyboard (the serial device doesn't seem to have an emulation option).
