This repository contains the supplementary files of the above article.
1. "Experimental materials.pdf" contain the experimental materials and the fillers.
2. "islands_analysisScript.R" is a script created to analyse the data with R.
3. "islands_data.csv" contains the preprocessed data from the experiment (note that this file includes the data of participants that were later excluded - see line 160 of the analysis script).
4. "Supplementary analyses.pdf" shows the complete results of Bayesian modelling.
5. WMScores.csv" contains the results of the operation span task (working memory task). The analysis script merges this file with islands_data.csv on line 143.
**Further information on the data files**
islands_data.csv contains the following columns:
- Participant: Participant ID
- L1: First language
- Age
- Gender
- Hand: left / right handed
- Education: Education level, which was either university or high school/vocational training (coded as "bachillerato/FP" in the data).
- Impairment: Indicates whether participants reported a language or reading impairment in the demographic questionnaire.
- OtherLang: Indicates other languages spoken by the participants.
- YearsOutsideAsturias: Years participants lived outside the region Asturias (northern Spain), where the experiment was carried out.
- LivesInAsturias: Indicates whether the participant was living in Asturias at the time of testing.
- Condition: Filler conditions (filler_grammatical, filler_ungrammatical), island conditions (short_nonisland, short_island, long_nonisland, long_island)
- Item: Item number
- Order: Position a the sentence in the presentation list.
- Response: accepted (the participant considered the sentence "acceptable"/rejected (the participant considered the sentence "unacceptable")
- RT: Reaction time.
WMScores.csv contains the following columns:
- Participant: Participant ID
- WMPartialCreditUnit: Working Memory partial credit unit score (used for analysis in the current study, following recommendation by Conway et al. 2005).
- WMAllOrNothingUnit: Working Memory all or nothing credit unit score.
- WMPartialCreditLoad: Working Memory partial credit load score.
- WMAllOrNothingLoad: Working Memory all or nothing load score.
- WMEquationAccuracy: Accuracy in solving the equations.
