BuscaPalabras: a program for deriving orthographic and phonological neighborhood statistics and other psycholinguistic indices in Spanish.

This article describes a Windows program that enables users to obtain a broad range of statistics concerning the properties of word and nonword stimuli in Spanish, including word frequency, syllable frequency, bigram and biphone frequency, orthographic similarity, orthographic and phonological structure, concreteness, familiarity, imageability, valence, arousal, and age-of-acquisition measures. It is designed for use by researchers in psycholinguistics, particularly those concerned with recognition of isolated words. The program computes measures of orthographic similarity online, with respect to either a default vocabulary of 31,491 Spanish words or a vocabulary specified by the user. In addition to providing standard orthographic and phonological neighborhood measures, the program can be used to obtain information about other forms of orthographic similarity, such as transposed-letter similarity and embedded-word similarity. It is available, free of charge, from the following Web site: www.maccs.mq.edu.au/-colin/B-Pal.
