Los sesgos cognitivos son errores sistemáticos de nuestro razonamiento. Mediante el término "correlación ilusoria" nos referimos a la tendencia a sobreestimar la existencia de covariación entre dos eventos. En un estudio reciente (Rodríguez-Ferreiro y Barberia, 2017) exploramos la posible relación entre este sesgo cognitivo y las preocupaciones morales.

We further explored these findings by studying the relation between illusory correlation and moral values. According to the moral foundations theory, liberals and conservatives differ in the relevance they concede to different moral dimensions: Care, Fairness, Loyalty, Authority, and Purity. Whereas liberals consistently endorse the Care and Fairness foundations more than the Loyalty, Authority and Purity foundations, conservatives tend to adhere to the five foundations alike. In the present study, a group of participants took part in a standard illusory correlation task in which they were presented with randomly ordered descriptions of either desirable or undesirable behaviors attributed to individuals belonging to numerically different majority and minority groups. Although the proportion of desirable and undesirable behaviors was the same in the two groups, participants attributed a higher frequency of undesirable behaviors to the minority group, thus showing the expected illusory correlation effect. Moreover, this effect was specifically associated to our participants' scores in the Loyalty subscale of the Moral Foundations Questionnaire. These results emphasize the role of the Loyalty moral foundation in the formation of attitudes towards minorities among conservatives. Our study points out the moral system as a useful fine-grained framework to explore the complex interaction between basic cognitive processes and ideology.

We carried out an experiment using a conventional causal learning task but extending the number of learning trials participants were exposed to. Participants in the standard training group were exposed to 48 learning trials before being asked about the potential causal relationship under examination, whereas for participants in the long training group the length of training was extended to 288 trials. In both groups, the event acting as the potential cause had zero correlation with the occurrence of the outcome, but both the outcome density and the cause density were high, therefore providing a breeding ground for the emergence of a causal illusion. In contradiction to the predictions of associative models such the Rescorla-Wagner model, we found moderate evidence against the hypothesis that extending the learning phase alters the causal illusion. However, assessing causal impressions recurrently did weaken participants' causal illusions. ; This study was supported by the grant PSI2016-75776-R (AEI/FEDER, UE) from Agencia Estatal de Investigación of the Spanish Government and the European Regional Development Fund to IB.

Function words and, more specifically, articles have been widely indicated as one of the main sources of difficulty for children with Developmental Language Disorder (DLD). The present study is the first to assess the online comprehension of Spanish articles in bilingual children with DLD. In an eye tracking experiment, we monitored participants' eye movements as they listened to Spanish articles embedded in structurally simple sentences. Ninety-six subjects from four different groups were evaluated: 24 children with DLD (average age 7;08), 24 children with the same chronological age (average age 7;08), 24 younger children matched for mean length utterance (average age 6;08), and 24 adults (average age 22;05). We calculated the proportion between the preference for the correct visual referent and a competitor object. Our results suggest that children with DLD are capable of timely comprehension of Spanish articles in real time and within simple sentence structures. However, we observed a strong effect of chronological age in the sample of interest; younger children with DLD are able to identify the correct referent, but this preference is weaker compared to the older children with DLD. We also observed local differences between the DLD group, and the other two children control groups, particularly when the chronological age group is introduced as a factor. These findings suggest a developmental trajectory that is different in the DLD group relative to children with typical language development. Notwithstanding, in spite of the article production difficulties previously reported, children with DLD in the present sample appear to be able to comprehend Spanish articles in the current experimental conditions. ; Ministry of Economy and Competitiveness of Spain EDU2013-44678-P ANID/PIA/Basal Funds for Centers of Excellence FB0003 Comisión Nacional de Investigación Científica y Tecnológica (CONICYT) CONICYT FONDECYT 11171074 11160657 ANID (National Agency for Research and Development, Government of Chile)
