Advertisements intend to persuade the reader to invest money or time in a product or service. Newspapers contain advertisements that are space-limited, thus necessitating a concise and convincing message that will influence readers. Nord (2008) analyzed conative function (Jakobson 1960) as a persuasive tool in a corpus of Spanish, English, and German advertising texts. A portion of Nord's study focused on sender attitude indicators directed at addressees as a key element of conative function, and analyzed address forms among several attitude indicators found in print advertisements. The current study analyzed 604 Spanish newspaper advertisements in Arizona and Florida, focusing on possible independent factors related to the probability of the occurrence of various address forms. These factors included: the type of product being advertized and its cost, the nature of the advertisement, the location of the advertisement in the newspaper (main section, sports, etc.), intended audience (including age and sex), geographic region of the newspaper, and each newspaper as compared to others. These variables were categorized and statistically analyzed using a quantitative design. The study provided results indicating a strong statistical relationship between the presence of address forms and product type, a moderate relationship with audience age, and a mild relationship with product cost. Various similarities and differences were also found when comparing the data geographically.
