Assemble a word-vs-pseudoword lexical-decision set from a candidate pool

Real words are drawn by an even spread across the byte-ordered pool, then a length-matched pseudoword is generated for each. The pool is first filtered to lower-case a-z forms, the only ones the pseudoword generators are defined for, so the eligible pool can be smaller than the request; the pipeline's shortfall policy then decides whether that errors. reference_words (the full lexicon) supplies the bigram statistics and the real-word list a pseudoword must avoid. The presented string is the target column; conditions are word and pseudoword and set pairs them.

Usage

build_lexdec_stimuli(
  pool,
  n,
  reference_words = NULL,
  method = "letter_substitution"
)

Arguments

pool

Data frame of candidate words, e.g. from build_pool().

n

Number of real words to select.

reference_words

Character vector supplying the bigram statistics and the real word forms a pseudoword must avoid; defaults to the pool's words.

method

Pseudoword generator: "letter_substitution" (default) or "subsyllabic" (Wuggy-style; Keuleers & Brysbaert, 2010).

Value

A stimulus data frame with target, condition and set columns.
