lexample {ndl}

Lexical example data illustrating the Rescorla-Wagner equations

Description

Ten monomorphemic and inflected English words with fictive frequencies, and meanings.

Usage

data(lexample)

Format

A data frame with 10 observations on the following 3 variables:

Word

A character vector specifying word forms

Frequency

A numeric vector with the – fictive – frequencies of occurrence of the words

Outcomes

A character vector specifying the meaning components of the words, separated by underscores
