RESUMO

The effect of contextual information about the national ingroup on explicit and implicit attitudes towards a novel brand was studied on a sample of university students from the Lima Metropolitan area (n = 59). The results show that the negative information about the ingroup exerts more influence on explicit attitudes towards a novel brand than the positive information. This effect is understood as a habituation of Peruvians towards the positive contextual information about their group, and an ingroup bias that acts when their national identity is threatened by the negative input. This bias guides them towards explicitly favoring a product they consider related to their social identity. On the other hand, the lack of visible results on the implicit attitudes is explained by the order effect of the Implicit Attitudes Test (IAT). These findings are relevant for advertising and marketing industries in Peru, which constantly develop campaigns that extol Peru and the Peruvian identity.


El efecto de la información contextual sobre el endogrupo nacional en las actitudes explícitas e implícitas hacia una marca novedosa fue estudiado en una muestra de estudiantes de la ciudad de Lima (n = 59). Los resultados muestran que la información negativa sobre el endogrupo ejerce mayor influencia que la información positiva en las actitudes explícitas hacia una marca novedosa. Este efecto es entendido como una habituación de los peruanos hacia la información contextual positiva acerca del endogrupo, y a un sesgo endogrupal que actúa cuando la identidad nacional se ve amenazada por información negativa. Este sesgo guía a los participantes a favorecer explícitamente aquel producto que consideran está relacionado con su identidad social. Por otra parte, la falta de resultados visibles en las actitudes implícitas es explicada por el efecto del orden del Test de Actitudes Implícitas (IAT). Estos hallazgos son relevantes para las industrias de marketing y publicidad en el Perú, las cuales constantemente desarrollan campañas que exaltan el Perú y la identidad peruana.

RESUMO

Objective To examine the effect of positive and negative evaluative conditioning (EC) on neutral faces.Methods The experiment consisted of three phases:baseline phase,conditioning phase,and re-evaluative phase,in which 41 college students participated,watching sequences of neutral faces (CS) pairing to either a positive stimulus (USpos) or a negative stimulus (USneg).Their emotional experiences (valence and arousal) and physiological reactivity (eyeblink startle reflex and skin conductance) were recor ded.Results (1) In the re-evaluative phase,CSpos was rated significantly more positive than CSneg and CSneut,while CSneg was rated significantly more negative than CSneut (CSpos (5.05± 1.24),CSneg (3.73± 1.48),CSneut (4.46± 1.04),P<0.05).(2)In the re-evaluative phase,the mean startle eyeblink response magnitude(T score) to CSpos was significantly smaller than the responses elicited by CSneg and CSneut (CSpos (45.04±5.56),CSneg (51.44±9.30),CSneut (54.52± 10.60),P<0.01).Conclusion The findings suggest that neutral faces can acquire valences and approach motivation through EC.

RESUMO

This study examines if the blocking effect paradigm predicts causal judgments when consequences of events vary in valence and magnitude. The procedure consists on presenting participants with reports describing the positive or negative effects produced by different substances, when these are consumed either separately or simultaneously with others. Two groups of participants were exposed to high and low magnitude consequences, respectively. The extent to which behavior with respect to causal judgments is consistent with the predictions of the blocking effect was evaluated in in both groups using two types of questions. One of them asked whether or not substance X produced the effect, while the other one asked about the probability of substance X producing the effect. Differences in causal judgments as a product of logical or intuitive reasoning were examined. Even though the blocking effect was not observed, a significant interaction was obtained between the factors valence and experimental condition (blocking and control). Findings are discussed in terms of the differences between associative learning in humans and in non-human animals, and in terms of the theoretical differences between evaluative conditioning and predictive or causal conditioning.


El propósito de este proyecto es examinar si el modelo de bloqueo predice la atribución de juicios causales al variar la valencia y la magnitud de las consecuencias. El arreglo experimental consiste en la presentación de reportes sobre los efectos positivos y negativos que producen diferentes sustancias al ser consumidas solas o en conjunto con otras. Los participantes del primer grupo estuvieron expuestos a consecuencias de alta magnitud y los del segundo grupo, a consecuencias de baja magnitud. Se evaluó si la atribución de causalidad es consistente con las predicciones del efecto bloqueo mediante dos tipos de pregunta: una pregunta acerca si la sustancia X produce o no el efecto, y una pregunta sobre la probabilidad de que X produzca el efecto. Se examinaron las diferencias en los juicios causales cuando las atribuciones son producto del razonamiento lógico o intuitivo. Si bien no se observó evidencia del efecto bloqueo, se obtuvieron efectos de interacción entre los factores valencia y condición experimental (sustancias bloqueo y control). Se discuten los hallazgos en términos de las diferencias entre el aprendizaje asociativo en humanos y animales no humanos, y en términos de las implicaciones sobre las diferencias teóricas entre el condicionamiento evaluativo y el condicionamiento predictivo.
