The what and why of self-deception

Self-deception: Distorted metacognitive process in ambiguous contexts

As one of the commonly used folk psychological concepts, self-deception has been intensively discussed yet is short of solid ground from cognitive neuroscience. Self-deception is a biased cognitive process of information to obtain or maintain a false belief that could be both self-enhancing or self-diminishing. Study 1 (N = 152) captured self-deception by adopting a modified numerical discrimination task that provided cheating opportunities, quantifying errors in predicting future performance (via item-response theory model), and measuring the belief of how good they are at solving the task (i.e., self-efficacy belief). By examining whether self-efficacy belief is based upon actual ability (true belief) or prediction errors (false belief), Study 1 showed that self-deception occurred in the effortless (easier access to answer cues) rather than effortful (harder access to answer cues) cheating opportunity conditions, suggesting high ambiguity in attributions facilitates self-deception. Studies 2 and 3 probed the neural source of self-deception, linking self-deception with the metacognitive process. Both studies replicated behavioral results from Study 1. Study 2 (ERP study; N = 55) found that the amplitude of frontal slow wave significantly differed between participants with positive/self-enhancing and negative/self-diminishing self-deceiving tendencies in incorrect predictions while remaining similar in correct predictions. Study 3 (functional magnetic resonance imaging study; N = 33) identified self-deceiving associated activity in the anterior medial prefrontal cortex and showed that effortless cheating context increased cheating behaviors that further facilitated self-deception. Our findings suggest self-deception is a false belief associated with a distorted metacognitive mental process that requires ambiguity in attributions of behaviors.

DESENTENDIMIENTO MORAL Y ATRIBUCIÓN DE CULPA: ENCUENTROS Y DESENCUENTROS EN EL ESTUDIO DE LA COGNICIÓN MORAL

El estudio de la cognición moral pareciera estar marcado por dos tradiciones: una centrada en el estudio del procesamiento de información referente a la causalidad y la intencionalidad, y otra que, con origen en posturas sociocognitivas, privilegia la agencia moral y regulación conductual más allá del procesamiento. Así, pareciera existir una brecha entre el estudio del razonamiento y el estudio de la conducta cuando se habla de moral. La presente propuesta muestra una interacción entre un modelo de culpa (path model) centrado en el procesamiento de información y el Desentendimiento Moral (DM) como un conjunto de mecanismos que surgen para justificar la conducta inmoral. Si bien la integración no es completa, aporta a una visión de la cognición moral centrada en la regulación social y en las interacciones entre juicios y respuestas evidentes en las interacciones sociales. Adicionalmente, como producto de la interacción se presenta una propuesta metodológica para indagar por el origen del DM en el desarrollo.

Self-Enhancement and Psychological Adjustment: A Meta-Analytic Review

This article advances the debate about costs and benefits of self-enhancement (the tendency to maintain unrealistically positive self-views) with a comprehensive meta-analytic review (299 samples, N = 126,916). The review considers relations between self-enhancement and personal adjustment (life satisfaction, positive affect, negative affect, depression), and between self-enhancement and interpersonal adjustment (informant reports of domain-general social valuation, agency, communion). Self-enhancement was positively related to personal adjustment, and this relation was robust across sex, age, cohort, and culture. Important from a causal perspective, self-enhancement had a positive longitudinal effect on personal adjustment. The relation between self-enhancement and interpersonal adjustment was nuanced. Self-enhancement was positively related to domain-general social valuation at 0, but not long, acquaintance. Communal self-enhancement was positively linked to informant judgments of communion, whereas agentic self-enhancement was linked positively to agency but negatively to communion. Overall, the results suggest that self-enhancement is beneficial for personal adjustment but a mixed blessing for interpersonal adjustment.
