In XSLmodels: Run and Optimize Cross-Situational Word Learning Models

Vlach & DeBrock (2017) spaced/massed repetition experiment data

Description

An xslData object from Vlach, H. A., & DeBrock, C. A. (2017). "Remember dax? Relations between children's cross-situational word learning, memory, and language abilities." Journal of Memory and Language, 93, 217-230. 12 to-be-learned word-object pairs (symmetric design: word i pairs with object i), 2 pairs per training trial, 36 trials; pairs vary in whether their 6 repetitions fall on consecutive trials (massed) or are spread out (spaced), the paper's memory/spacing manipulation. n_subj is 47 children (ages 2-5).

Usage

vlach_debrock2017

Format

An object of class xslData (inherits from list) of length 8.

Details

No per-word accuracy is available from this dataset, only the paper's overall mean across all pairs and participants (accuracy = .5583, sd = .1975; see data-raw/XSL-dataset-fields.csv), so accuracy is NA throughout. Not included in xsl_datasets and not scorable by xsl_run()'s built-in per-item SSE – usable for running/fitting models and comparing simulated performance against the one real number this paper reports. See data-raw/add_vlach_debrock2017.R for construction details.

Examples

m <- xsl_run(baseline(), vlach_debrock2017)$fits[[1]]$matrix
