Effects of LSA Measures of Retrieval and Selection Demands on Reaction Times in the Verb Generation and Sentence Completion Tasks

	t(36)	p	Effect size (r²)
Verb Generation
LSA strength	-14.04	<.001	.845
LSA ratio	-6.05	<.001	.504
Sentence Completion
LSA strength	-7.57	<.001	.614
LSA ratio	-10.25	<.001	.745

Note. Purer LSA-based measures challenge previous findings and existing accounts of underdetermined responding: Reaction times are predicted by both strength and ratio, measures of retrieval and selection demands, respectively. All effects are controlling for the other variable in the model.
