Statistics & Experimental Psycholinguistics: Part 2

Carina Pinto

Discussion

Portuguese

When choosing an experimental methodology, researchers typically pick those that are widely used as a means of validating the results. However, by carefully reading some of the most relevant studies published, we find that there are no canonical practices—the experimental designs vary greatly, but the choices made are not justified. This session aims to bring this discussion to light by analyzing the following characteristics of experimental design:

  • Linguistic stimuli: types of prime; types of target; types of pseudowords; types of fillers; number of stimuli; number and type of conditions

  • Experimental procedures: experimental sequence (attachment point, pre-mask, prime¸ mask and target); orthographic features (font type, font size, use of upper and lower case, background color, other graphic features); exposure times (attachment point, pre-mask, prime, mask and target)

  • Informants: number of informants; profile of informants; language; linguistic evaluation of informants; other characteristics (laterality, vision, deviations)

  • Data collection software

  • Data exclusion: (right answers, total answers, independent consideration of wrong answers); exclusion of informants

  • Statistical analysis: descriptive statistics, inferential statistics and linear models.
