Data and code

Shiny data exploration app

Running the included shiny app will allow you to explore individual participants’ response patterns. It offers a way of getting a sense of what the data represents without mucking about with the data files themselves.

explore_data()

You can access an already-deployed version of the shiny app at https://richarddmorey.shinyapps.io/explore/.

The app will let you:

• Search, sort, and filter the data set by experimental condition, response, etc.
• See the selected participant’s interface at the poiint of decision (both experimental samples and random shuffle reports)
• See an animation showing the selected participant’s behaviour over time, up to the point of decision
• Read the selected participant’s responses to the questions about their strategy
• Search the strategy text using POSIX regular expressions, optionally (try “chance” to search for all instances of “chance”; “color|colour” will search for mentions of either of the two spelling variants of “color”)

Cleaned data

The cleaned data with text responses are made available in the package in the following objects.

Object	Description
christmas_stats_participants	Summary information about each participant, including text responses
christmas_stats_samples	Every individual sample made by each participant
text_coding	The categorizations of each participant’s open-ended strategy text responses

Compressed data

Because the original csv file downloaded from Qualtrics has the timestamped information for each experiment for each participant in it, the file is quite large. It is stored in compressed in a zip file in the subfolder inst/extdata/ to save space. You can load the original file in R using the command:

load_complete_dataset()

This will unzip the Qualtrics CSV file and check it against an MD5 hash. It will also do some light cleaning (filtering out non-respondents and rejected mobile users and filtering/renaming columns).

Analysis code

All analysis code is available as package functions, from initial cleaning to figures.

Function	Description
load_complete_dataset()	Reads original data from csv file and performs initial filtering
compile_complete_dataset()	Compile the data, separating out the individual participant experimental samples and performing appropriate re-coding, etc.
load_clean_dataset()	Main cleaning of the data set to reduce the sample down to only those that will be analyzed
load_text_responses()	Load the text responses separately for convenience
