Item Bayesian reasoning with emotional material in patients with schizophrenia.(Frontiers in Psychology, 2022) Romero-Ferreiro, Verónica; Susi, Rosario; Sánchez-Morla, Eva M.; Marí-Beffa, Paloma; Rodríguez-Gómez, Pablo; Amador, Julia; Moreno, Eva M.; Romero Ferreiro, Carmen; Martínez-García, Natalia; Rodriguez-Jimenez, RobertoDelusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of beads of 60:40 and 80:20, considered, respectively, as the “difficult” and “easy” variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients’ deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task (i.e., ambiguity and content) in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning.Item Cognitive versus emotional modulation within a Stroop paradigm in patients with schizophrenia.(BJPsych Open, 2023) Romero-Ferreiro, Verónica; García-Gutiérrez, Ana; Torio, Iosune; Marí Beffa, Paloma; Rodríguez-Gómez, Pablo; Periáñez, José A.; Moreno, Eva M.; Romero Ferreiro, Carmen; Alvarez-Mon, Miguel Ángel; Rodríguez Jiménez, RobertoBackground Schizophrenia is a complex disorder involving deficits in both cognitive and emotional processes. Specifically, a marked deficit in cognitive control has been found, which seems to increase when dealing with emotional information. Aims With the aim of exploring the possible common links behind cognitive and emotional deficits, two versions of the emotional Stroop task were administered. Method In the cognitive-emotional task, participants had to name the ink colour (while ignoring the meaning) of emotional words. In contrast, the emotional-emotional task consisted of emotional words superimposed on emotional faces, and the participants had to indicate the emotional valence of the faces. Fifty-eight participants (29 in-patients diagnosed with schizophrenia and 29 controls) took part in the study. Results Patients and controls showed similar response times in the cognitive-emotional task; however, patients were significantly slower than controls in the emotional-emotional task. This result supports the idea that patients show a more pronounced impairment in conflict modulation with emotional content. Besides, no significant correlations between the tasks and positive or negative symptoms were found. This would indicate that deficits are relatively independent of the clinical status of patients. However, a significant correlation between the emotional-emotional task and cognitive symptoms was found. Conclusions These findings suggest a restricted capacity of patients with schizophrenia to deal with the attentional demands arising from emotional stimuli.
