The Influence of language categorization on face perception

As the world experiences increased international mobility, we encounter those from different racial, ethnic, and linguistic backgrounds. Therefore it is increasingly crucial to examine the ways we categorize and perceive other people. The main objective of this dissertation is to examine whether lan...

Therefore it is increasingly crucial to examine the ways we categorize and perceive other people. The main objective of this dissertation is to examine whether language is a dimension of social categorization, and whether this affects face perception. We also examined whether language categorization interacts with race categories, and whether this interaction affects the perception of other race faces. These issues were investigated in three studies. Firstly, we used behavioral and event-related potential techniques in an oddball paradigm to test whether language categorization affects visual face perception. We demonstrated that indeed, language is used as a social category, and this categorization affects the early stages of visual perception of faces. Secondly, we examined how language interacts with race in creating social categories. By using a popular psychological paradigm called the Memory Confusion Paradigm, we establish the robustness of language categorization, and the malleability of race categorization when crossed with different language contexts. In our final study, our aim was to understand whether native and foreign accents affect the perception and recognition of other-race faces. In summary, this dissertation has examined the effect of language on face perception, and has established that language categorization is a strong and robust effect that influences face perception. Como resultado del incremento en la movilidad internacional que el mundo está experimentando, es común encontrar gente de otra raza y con orígenes étnicos y lingüísticos diferentes. Así pues, es cada vez más crucial examinar cómo categorizamos y percibimos a otros. El objetivo principal de la presente tesis es examinar si el lenguaje es una dimensión de social categorización y como afecta la percepción de la cara. Además, examinamos si la categorización lingüística interactúa con las categorías raciales y si esta interacción afecta la percepción de aquellas caras con raza diferente a la nuestra. Todas estas cuestiones se investigaron en tres estudios. Primero, mediante medidas conductuales y electrofisiológicas en un paradigma de detección del cambio (oddball paradigm) se investigó si el lenguaje se usa como categoría social y si tal categorización afecta estadios tempranos en la percepción visual de la cara. Segundo, se examinó como el lenguaje interacciona con la raza a la hora de crear categorías sociales. Por medio del paradigma psicológico de la confusión de memoria (Confusion Memory Paradigm), establecimos la robustez de la categorización lingüística y la maleabilidad de la categorización racial en diferentes contextos lingüísticos. Finalmente, el último estudio tenía por objetivo entender si acentos nativos y extranjeros pueden modular la percepción y el reconocimiento de caras de otra raza. En resumen, esta tesis ha examinado el efecto de lenguaje en la percepción de la cara y ha mostrado que la categorización lingüística es un efecto fuerte y robusto que influye la percepción de la cara.
