The design of experimental tasks in psychology and linguistics requires using stimulus with properties and characteristics in standardized values. This allows predicting with higher accuracy the impact of the stimulus presentation. The lexical associative norms are instruments that determine the strength of association between two concepts. The most common method to construct these norms is to take a free response from a presentation of a cue word. The main goal of this study was to construct lexical associative norms of 407 Spanish words. 800 students from Ciudad de Córdoba, Argentina, participated in the study. Quantitative analyses were performed taking into account the number of valid answers, blank and non valid answers, and number of associates per item. A qualitative classification was performed according to the strength of association. Additionally, it is presented a group of psycholinguistic indexes for a better description of the items used. Correlation analysis demonstrated a strong and negative relation between the frequency of first and second associations and the number of associations per item. This study pretends to be highly useful in research in psychology and linguistic where it is required consulting the norms presented to the design of evaluation instruments.
