Hi all,
I do really apologise if this is a stupid question (and yes, they exist :-))
But...I have a survey with two embedded experiments.
However, I just cannot seem to find the data for the experiments.
What is the easiest way to link the answers that participants gave to the questions to their performance in the experiments?
The data files for the surveys only give me the responses to the questions, I cannot find the data for the experiments at all..never mind finding a way to link the survey responses to their performance in the experiments.
Thanks!

Hi there, if you have saved any data in your experiment using save, than you should be able to download a zip-file containing a txt-file of experiment data for each participant and Excel- and csv-files with the survey data, which includes the experiment name in its file name. The data for download is at the end of the page, which you used for coding your survey.
Do you want to have the data of the experiment and the survey data in one file together for analysis or do you want something to happen at the end of your study in accordance of an answer to a survey question and performance during an experiment? |

Basically I score them on certain personality traits based on their answers in the survey questions and I want to see if the presence of certain traits affects their reaction times/accuracy in the experiment.
So I need to be able to link survey answers with experiment performance.

This is a very typical way of doing a PsyToolkit experiment.
It is straightforward and not difficult.
There is good documentation online on how to do this, check out this lesson which takes you through all the steps:

Hi everyone,
I have a problem with my downloaded data. I really appreciate it if someone can help me with this. I created a survey with some embedded experiences. I was wondering how can I have the results for my survey and experiments in one file? I followed the steps provided here but I just have different files for experiments and I can not match them to the survey. I do not know the results are for which participants.
Much thanks!

Hi, you might find the introduction to R provided by PsyToolkit useful, which can be found here. This allows you to load all files and then match your data accordingly. All files will contain the unique participant ID, which PsyToolkit automatically gives every person, who participates in your experiments. Using this ID you then can match the responses from the survey with the data from the experiments. Some files contain the ID while others have the ID in their file name. |

Hi,
I am having some problems with this feature also. I manage to analyze data according to the parameters set under ‘Analyze’ both for data generated by the experiment and with uploaded data. Both analysis of one data file and analysis of multiple files produces correct results. However, I cannot get this to function with my survey. All I get are the raw data files, data.xlsx and data_times.xlsx which both have the survey items and timing for those but holds no columns with data from the experiment. I am missing the additional columns that holds mean RT etc..
I have tried to prepare the datafiles multiple times before downloading the zip file.

I have the exactly same issue. I can find data from my embedded experiment in downloaded file in .txt form. However, they are not included in excel files. How it is possible? To be honest I was a little bit confused about the usage of TABLE function. It is necessary to use it in every experiment design? Mine works well without it.

I am in the same boat as others.
I get a "data" and "data_times" file (csv and xls) but don't appear to have anything with the actual response times. I have all the text files that do appear to include that info (9 columns, which reasonably look to correspond to the multitasking experiment info in the experiment library).
It's like it isn't include anything from the experimental part of the study and is only grabbing the info from the "survey".

That is correct, the data files only contain survey related information apart from the corresponding experiment file name. The "data" file contains the participant ID, the answers to the survey questions, the file name of the experiment file corresponding to each participant, and time information for the whole thing (start, end, time needed overall).
The "data_times" file includes the participant ID and the "reaction times" to each survey question. This is the time from the question appearing until the continue button was clicked on.
You will only have reaction times for your embedded experiment in the TXT-files, if you have saved those using "save" and a variable containing the reaction time at some point in a task in your experiment script. The reaction times of the embedded experiment will not appear in the "data" files.

After setting up ‘Analyze’ for the embedded experiment according to the instructions for Step 6 found here: www.psytoolkit.org/lessons/project.html it still does not produce the data. As I understand now it should produce additional csv and xlsx data files containing mean and median RT data where the data rows in those data files corresponds to each participant in the data.xlsx and data_times.xlxs data files. These additional data files for the embedded experiment are not created. |

As far as I understand it, this does not happen automatically after you set up the columns of interest in the analysis section of the experiment page. You still have to upload or copy and paste the data you want to analyze. There is a limit to 3 files. A work-around could be combining all txt-files into one txt-file and upload that one. Personally, I recommend using a separate software for analysis, for example R.

You should be able to download the additional data files (rt, etc.) from the embedded experiment in your study for all your participants if you define your columns under 'Analyze'.

You are right. According to the video, which shows the download of the data files, separate files for analysed data, e.g. median or mean, should be in the ZIP-file as well. I have not realized this until now as I am always reading the data into R. Have you double-checked that the column numbers are referring to the right information? If you are referring to a certain block, is that one written correctly? In one of my last experiments I defined the columns for a certain block in the analysis section just for fun, but I did not get the separate files when downloading the data. How very odd.

Yes, all parameters are correctly defined as shown by the output analysis generated in the analysis section. There is however, no generation of additional RT files upon download.
