Two studies compared the relative strength of motivational assumptions drawn from SIT (e.g. Tajyel, 1978) and memory-based assumptions drawn from the differential familiarity hypothesis (Linville, Fischer and Salovey, 1989) in explaining ingroup bias and the black sheep effect (Marques, 1986(Marques, , 1990

Social cognitive impairment is a key feature of schizophrenia and social cognition training (SCT) is a promising tool to address these deficits. Neurobiological dysfunction in schizophrenia has been widely researched, but neuronal changes induced by SCT have been scarcely explored. This review aims to assess the neuroplastic effects of SCT in patients with schizophrenia spectrum disorders. PubMed and Web of Science databases were searched for clinical trials testing the effects of SCT in functional and structural brain measurements of adult patients with schizophrenia or schizoaffective disorders. A total of 11 studies were included: five used fMRI, two used EEG and ERP, one used ERP only, two used MEG and one study used MRI. Data extracting and processing regarding sociodemographic and clinical variables, intervention characteristics, neuroimaging procedures, neuroplastic findings, effect sizes and study quality criteria was completed by two raters. Results indicate a wide range of structural and functional changes in numerous regions and circuits of the social brain, including early perceptual areas, the limbic system and prefrontal regions. Despite the small number of trials currently available, evidence suggests that SCT is associated with neuroplastic changes in the social brain and concomitant improvements in social cognitive performance. There is a lack of extensive knowledge about the neural mechanisms that underlie social cognitive enhancement after treatment, but the reported findings may shed light on the neural substrates of social cognitive impairment in schizophrenia and how improved treatment procedures can be developed and applied.

The COVID-19 pandemic is a worldwide threat to public health and the global economy. The climate of fear and uncertainty associated with the pandemic has fostered the emergence of a wide-range of COVID-19 conspiracy theories that has the potential do shape public opinion and hinder the effective dissemination of valid information. Beliefs in conspiracy theories has been associated with maladaptive personality traits such as schizotypy and paranoia, as well as other non-psychotic psychological characteristics (e.g., social isolation, stress). The current study aimed to examine the association between beliefs in COVID-19 conspiracy theories and psychotic-like experiences within the community, while also addressing the role of sociodemographic information, psychological outcomes (e.g., stress, affective states) and other pandemic-related factors (e.g., confinement conditions/behaviors). Our results suggest that psychotic-like experiences are associated with beliefs in COVID-19 conspiracy theories, particularly perceptual abnormalities and persecutory ideation. Moreover, increased health-related concerns and reduced education levels also seem to be liability factors for these conspiracy beliefs. These results add important insights into how the adherence to illogical and erroneous disease-related arguments may be contingent to proneness to psychotic-like experiences. COVID-19 conspiracy theories are yet another major challenge that governments and policy makers must contemplate when defining strategic directions to manage the current and future pandemics.

Results indicate that cognition contributes to some of the behavioural problems displayed by inmates in the prison context. Future studies should evaluate the role of programmes to improve cognitive processes in also improving prison behaviour and also test for continuities and discontinuities with post-release integrative success.
