Neural mechanisms of affective interference in schizotypy

Negatively valenced stimuli foster cognitive impairment in schizotypy and schizophrenia. To identify relevant brain mechanisms, the authors had 16 positive-schizotypy and 16 control participants perform an emotional Stroop task, judging the ink color of negative and neutral words during functional magnetic resonance imaging (fMRI) of regional brain activity. Schizotypy individuals showed increased right and decreased left activity in dorsolateral prefrontal cortex, indicating a deficit in maintenance of attentional set in the presence of negative emotional distractors. They also showed abnormal activity in ventral limbic areas, including decreased activity in nucleus accumbens and increased activity in hippocampus and amygdala, a circuit involved in the integration of cognitive and affective processes. These results indicate that aspects of emotion-cognition processes and the brain mechanisms that implement them are similar in schizotypy and schizophrenia.     

The discourse of being ‘triggered’: Uses and meanings among counselling students

Despite the initial understanding of the word ‘triggered’ as relating to the clinical phenomenon of post-traumatic stress disorder (PTSD), this language has become a common part of the vernacular today, used by many people to apply to a wide variety of experiences and events. Counselling students are particularly sensitised to trauma, as well as identity politics, and are familiar with trigger warnings at college. They themselves have experienced trauma at high rates. Therefore, we were interested to understand how they might be using the word and interpreting the experience of being ‘triggered’, whether different sources of being triggered are related to emotional reactions, and whether a discourse analysis might indicate how and why the term has become useful and for what other experiences it might be serving as a stand-in. In this mixed-methods study, 79 counselling students from around the country shared their definitions and experiences of being ‘triggered’. Participants completed surveys and wrote narratives, which, via thematic qualitative analysis, were coded into five themes. The quantitative analysis focused on the relationship of feelings to themes and the relationship between anger suppression and coping with each theme. Discourse analysis explored how individuals wrote about responsibility and anger. It was discovered that those who wrote about being triggered from a past sexual assault did not discuss anger, nor the responsibility of others to protect them (as those who wrote about microaggressions did), but positioned themselves as overreactors. Results are discussed with regard to training and practice.     

Emotion-modulated performance and activity in left dorsolateral prefrontal cortex

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words prompted more activity in left than in right DLPFC. Response speed to pleasant words was correlated with DLPFC activity. These data directly link positive affect, enhanced performance, and prefrontal activity, providing some of the first fMRI evidence supporting models of emotional valence and frontal brain asymmetry based on electroencephalography (EEG).     

Little Bayesians or little Einsteins? Probability and explanatory virtue in children's inferences

Like scientists, children seek ways to explain causal systems in the world. But are children scientists in the strict Bayesian tradition of maximizing posterior probability? Or do they attend to other explanatory considerations, as laypeople and scientists – such as Einstein – do? Four experiments support the latter possibility. In particular, we demonstrate in four experiments that 4‐ to 8‐year‐old children, like adults, have a robust latent scope bias that leads to inferences that do not maximize posterior probability. When faced with two explanations equally consistent with observed data, where one explanation makes an unverified prediction, children consistently preferred the explanation that does not make this prediction (Experiment 1), even if the prior probabilities are identical (Experiment 3). Additional evidence suggests that this latent scope bias may result from the same explanatory strategies used by adults (Experiments 1 and 2), and can be attenuated by strong prior odds (Experiment 4). We argue that children, like adults, rely on ‘explanatory virtues’ in inference – a strategy that often leads to normative responses, but can also lead to systematic error.     

Specificity of meta-emotion effects on moral decision-making

A recently proposed dual process theory of moral decision-making posits that utilitarian reasoning (approving of harmful actions that maximize good consequences) is the result of cognitive control of emotion. This suggests that deficits in emotional awareness will contribute to increased utilitarianism. The present study explored the relative contributions of the different facets of alexithymia and the closely related constructs of emotional intelligence and mood awareness to utilitarian decision making. Participants (N = 86) completed the Toronto Alexithymia Scale, Trait Meta Mood Scale, the Mood Awareness Scale, and a series of high-conflict, personal moral dilemmas validated by Greene et al. (2008). A brief neuropsychological battery was also administered to assess the possible confounds of verbal reasoning and abstract thinking ability. Principal components analysis revealed two latent factors-clarity of emotion and attention to emotion-which cut across all three meta-emotion instruments. Of these, low clarity of emotion-reflecting difficulty in reasoning thoughtfully about one's emotions-predicted utilitarian outcomes and provided unique variance beyond that of verbal and abstract reasoning abilities. Results are discussed in the context of individual differences in emotion regulation.     

Obstacles to Personal Creativity between Brazilian and Mexican University Students: A Comparative Study

The study focused on personal obstacles to creativity between 385 Brazilian and 305 Mexican university students. The Obstacles to Personal Creativity Inventory, designed and validated by Alencar (1999b), was administered to these students. The results indicated that Lack of Time/Opportunity was the most frequent obstacle. Significant differences were observed between Brazilian and Mexican students in the cluster of obstacles named Lack of Motivation, and between male and female students in the cluster of obstacles named Inhibition/Shyness. The results point to several obstacles to personal creativity which are common among university students. These obstacles should be known by those involved in education in order for them to help students to be less susceptible to obstacles that hinder their creativity.
