Hello, 

I have an experiment where participants study faces and scenes, and will then be tested on their memory for the face scene pairings (study1-test1-study2-test2). I was able to get the study part working, where faces and scenes are initially randomly paired together during study1. During study2 the same scene-face pairings are presented again. 

However, we are having trouble with the test portion. For the study portion, the face and scene are presented next to each other (horizontal). However, for the test portion, One scene is presented in the top middle of the screen with three faces underneath.  In the test , we need the correct face to be presented with the correct scene, in addition to two additional faces. Here are two issues we are facing: 

1. The way we have it coded now, the pairings are saved with the scenes and faces in a specific, horizontal position. How do we show the same scene-face pairing from the study phase (horizontal) in the test phase with the scene on top of the face?

2. Ideally, the face choices would be the face initially paired with the scene, one random face, and one that was paired with a pairmate of the correct answer scene (arcade 1 and arcade 2). Right now we just have all of the scenes listed out in one item element and not grouped together by pairmates. Though they are ordered by pairmates (e.g., 1 & 2 go together, 3 & 4 together, etc.).  Is it possibly to have the test phase have The scene on top, and then three faces on the bottom that include: faces from the correct scene, its pairmate, and then a random face? If this is not possible, we need it so the other two faces are random and not the same as each other. 

Here is the code we have so far with a working study phase and in progress test phase. Any help is very much appreciated. Thank you for your time.

Hello, 

I have an experiment where participants study faces and scenes, and will then be tested on their memory for the face scene pairings (study1-test1-study2-test2). I was able to get the study part working, where faces and scenes are initially randomly paired together during study1. During study2 the same scene-face pairings are presented again. 

However, we are having trouble with the test portion. For the study portion, the face and scene are presented next to each other (horizontal). However, for the test portion, One scene is presented in the top middle of the screen with three faces underneath.  In the test , we need the correct face to be presented with the correct scene, in addition to two additional faces. Here are two issues we are facing: 

1. The way we have it coded now, the pairings are saved with the scenes and faces in a specific, horizontal position. How do we show the same scene-face pairing from the study phase (horizontal) in the test phase with the scene on top of the face?

2. Ideally, the face choices would be the face initially paired with the scene, one random face, and one that was paired with a pairmate of the correct answer scene (arcade 1 and arcade 2). Right now we just have all of the scenes listed out in one item element and not grouped together by pairmates. Though they are ordered by pairmates (e.g., 1 & 2 go together, 3 & 4 together, etc.).  Is it possibly to have the test phase have The scene on top, and then three faces on the bottom that include: faces from the correct scene, its pairmate, and then a random face? If this is not possible, we need it so the other two faces are random and not the same as each other. 

Here is the code we have so far with a working study phase and in progress test phase. Any help is very much appreciated. Thank you for your time.

Thank you so much. I apologize for not providing the additional information you asked for in time. I appreciate you sending this code anyway. It works great except that in the study phase it is only ever picking Face 1. On each trial the scene-face pairing should be unique. 

Thanks again for any help.

Hello, 

I have an experiment where participants study faces and scenes, and will then be tested on their memory for the face scene pairings (study1-test1-study2-test2). I was able to get the study part working, where faces and scenes are initially randomly paired together during study1. During study2 the same scene-face pairings are presented again. 

However, we are having trouble with the test portion. For the study portion, the face and scene are presented next to each other (horizontal). However, for the test portion, One scene is presented in the top middle of the screen with three faces underneath.  In the test , we need the correct face to be presented with the correct scene, in addition to two additional faces. Here are two issues we are facing: 

1. The way we have it coded now, the pairings are saved with the scenes and faces in a specific, horizontal position. How do we show the same scene-face pairing from the study phase (horizontal) in the test phase with the scene on top of the face?

2. Ideally, the face choices would be the face initially paired with the scene, one random face, and one that was paired with a pairmate of the correct answer scene (arcade 1 and arcade 2). Right now we just have all of the scenes listed out in one item element and not grouped together by pairmates. Though they are ordered by pairmates (e.g., 1 & 2 go together, 3 & 4 together, etc.).  Is it possibly to have the test phase have The scene on top, and then three faces on the bottom that include: faces from the correct scene, its pairmate, and then a random face? If this is not possible, we need it so the other two faces are random and not the same as each other. 

Here is the code we have so far with a working study phase and in progress test phase. Any help is very much appreciated. Thank you for your time.

Thank you so much. I apologize for not providing the additional information you asked for in time. I appreciate you sending this code anyway. It works great except that in the study phase it is only ever picking Face 1. On each trial the scene-face pairing should be unique. 

Thanks again for any help.

> in the study phase it is only ever picking Face 1

You can be sure I tested the code and it is not doing that. Attached a data file resulting from running the exact code as posted.

Hello, 

I have an experiment where participants study faces and scenes, and will then be tested on their memory for the face scene pairings (study1-test1-study2-test2). I was able to get the study part working, where faces and scenes are initially randomly paired together during study1. During study2 the same scene-face pairings are presented again. 

However, we are having trouble with the test portion. For the study portion, the face and scene are presented next to each other (horizontal). However, for the test portion, One scene is presented in the top middle of the screen with three faces underneath.  In the test , we need the correct face to be presented with the correct scene, in addition to two additional faces. Here are two issues we are facing: 

1. The way we have it coded now, the pairings are saved with the scenes and faces in a specific, horizontal position. How do we show the same scene-face pairing from the study phase (horizontal) in the test phase with the scene on top of the face?

2. Ideally, the face choices would be the face initially paired with the scene, one random face, and one that was paired with a pairmate of the correct answer scene (arcade 1 and arcade 2). Right now we just have all of the scenes listed out in one item element and not grouped together by pairmates. Though they are ordered by pairmates (e.g., 1 & 2 go together, 3 & 4 together, etc.).  Is it possibly to have the test phase have The scene on top, and then three faces on the bottom that include: faces from the correct scene, its pairmate, and then a random face? If this is not possible, we need it so the other two faces are random and not the same as each other. 

Here is the code we have so far with a working study phase and in progress test phase. Any help is very much appreciated. Thank you for your time.

(1) Please comment your code: Meaningful explanations of what each part is supposed to do.
(2) If your code requires external files to run (images, etc.) always provide those files along with it.
(3) In your questions, refer to any and all elements as they are named in the code. Otherwise it is difficult to discern what you are referring to.

Here's how I would set this up, so far as I can make sense of your description. You didn't provide the images, so I had to resort to using <text> elements as placeholders.

        list.scenePairedFaceItemnumbers.setitem(currentFace, i); // pair it with scene i
        if (mod(i, 2) == 1) { // if i is odd
            list.scenePairmateFaceItemnumbers.setitem(currentFace, i+1); // the face is the pairmate for scene i+1
        } else { // otherwise
            list.scenePairmateFaceItemnumbers.setitem(currentFace, i-1); // the face is the pairmate for scene i-1
        };
        i += 1;
    };
]
