Priming and lexical decision task - HELP!

jschiralli — Thu, 28 Sep 2017 12:33:38 GMT

Hi all,

I'm hoping to get some help with programming a lexical decision task (LDT) with 3 primes. The existing LDT script (Lepore & Brown, 2002) does not include the use of primes, so it would need to be added to the script (this is where I'm struggling). I've consulted previous threads on similar topics but not all of them are relevant, and my complete lack of coding/programming experience limits my understanding.

Essentially, this is the design of the task:
- 3 primes (the primes will be words - YOUNG, OLD, or XXXX)
- 4 word lists (containing 11 words each) and 1 non-word list (containing 44 non-words)

There should be 176 trials divided into 4 blocks of 44 trials each. The 44 traits (real words) should be paired with each of the 3 primes, yielding a total of 132 word trials. The word and non-word trials should be presented randomly across the 4 blocks. I would appreciate any feedback on how difficult this would be to program, particularly for a person who has no programming or Inquisit experience.

The goal is to be able to look at response/reaction time to each word list (category) depending on which prime was presented before it. From what I understand, I need to be able to see all 132 columns in the results to make these comparison.

The code currently does not run at all because the primes I added did not exist before (no idea if I have even written them correctly). There are other errors too, since I have added new words and lists. Please excuse any ignorance - I have zero programming experience.

This is all I have so far:

I don't necessarily think you should use the existing LDT script as a basis. Sometimes things are easier to build from scratch. Since you're new to Inquisit, I'd suggest you start with this priming-related tutorial: http://www.millisecond.com/support/docs/v5/html/tutorials/subliminal/subliminaltutorial.htm

Then, perhaps, take a look at this simple primed LDT example: https://www.millisecond.com/forums/FindPost18946.aspx
