lrd

lrd processes lexical response data from cued-recall, free-recall, and sentence-recall studies in R to automate coding and support quantitative evaluation of memory retrieval data.

Key Features:

• Automated coding: Automates coding of responses from cued-recall, free-recall, and sentence-recall tasks.
• R implementation: Implemented as an R package for computational processing of lexical response data.
• Recoding of large-sample outputs: Recodes output from large-sample studies to generate analyzable response datasets.
• Human-code comparison: Compares automated coding results to human coding to assess concordance.
• Performance evaluation: Evaluates the scoring algorithm using inter-rater reliability, sensitivity, and specificity metrics and reproduces human-coded results.

Scientific Applications:

• Memory retrieval research: Facilitates analysis of recall test data from cued-recall, free-recall, and sentence-recall paradigms.
• Validation and replication: Supports validation of automated scoring and replication of findings by enabling direct comparison between automated and human-coded data.

Methodology:

Validation consisted of recoding outputs from large-sample cued-recall, free-recall, and sentence-recall tasks, comparing automated results to human coding, and evaluating inter-rater reliability, sensitivity, and specificity of the scoring algorithm.
