LexOPS

LexOPS generates controlled word stimuli for psycholinguistic and cognitive psychology experiments by enabling specification of factorial designs and manipulation of lexical variables.

Key Features:

• Controlled Word Generation: Generates word lists that adhere to specified factorial design parameters to control experimental conditions.
• Language Adaptability: Supports adaptation for use with multiple languages.
• Inbuilt English Word Database: Provides an English word database annotated with lexical variables commonly used in psycholinguistic studies.
• Validation Analysis: Includes validation analyses indicating generated stimuli exhibit greater constraint and consistency in variable manipulation compared to existing studies.

Scientific Applications:

• Psycholinguistics: Facilitates experiments that require controlled manipulation of lexical properties.
• Cognitive Psychology: Enables design of cognitive psychology experiments that require precise control of word stimuli.
• Related Behavioral Research: Applicable to studies in related fields that depend on systematically controlled lexical stimuli.

Methodology:

Implements an R package interface to allow specification of factorial designs and generation of word lists using an inbuilt English word database.
