Creative Artistic Achievement Is Related to Lower Levels of Alexithymia

Alexithymia is characterized by deficits in the ability to identify, differentiate, and describe emotions—abilities that are of importance for social interactions, well-being, and, consequently, also for health. The aim of this study was to investigate whether achievements in cultural activities are associated with alexithymia. Participants from the Swedish Twin Registry were 2,279 men and 3,152 women in the ages 27 to 54. Cultural achievement was measured with the Creative Achievement Questionnaire (CAQ) in which participants estimate their achievement in the domains writing, music, visual arts, theater, and dance on a 7-point scale. Alexithymia was measured with the Toronto Alexithymia Score (TAS 20). In sex separated, age, and education-adjusted multivariate analyses, nonpractitioners, amateurs, and professionals in the 5 different CAQ domains were compared with regard to alexithymia scores. For both men and women, achievement in writing and music contributed statistically and independently of one another to a low alexithymia score. In addition, achievement in visual arts contributed independently to low alexithymia score in men and achievement in theatre to low alexithymia score in women. Total creative achievement was calculated as a sum score across domains, and the distribution divided into tertile groups. These groups were compared with regard to alexithymia scores. Large tertile differences were found in both sexes. The results show differences between modalities and cumulative effects of multiple creative achievements.     

Preventing clinical deterioration in the course of schizophrenia: the potential for neuroprotection

Schizophrenia, which has both genetic and environmental causes, is associated with persistent symptoms and severe functional disability. The illness lies dormant during the premorbid phase and begins to express itself during adolescence or early adulthood. Clinical progression and deterioration reaches a plateau in which the patient is said to be in the chronic phase of illness and at which point restoration of prior functioning is unlikely. The severe deficits associated with schizophrenia are often the result of progression of illness due to lack of appropriate treatment. However, recent advances in neuropsychiatry have led to very early identification of individuals at risk for psychosis, even during the prodromal stage when psychosis has not yet manifested clinically. While research has demonstrated that the efficacy of antipsychotics is limited when used during the chronic phase of illness, these medications can effectively control symptoms and prevent progression of illness when used during the early stages of illness. The evidence of neural degeneration in the pathophysiology of schizophrenic illness suggests that there may be treatment opportunities through neural protection. Neuroprotection, which refers to treatment that helps maintain central nervous system functionality in response to neurobiologic stress, may be responsible for prevention of disease progression and deterioration. In this monograph, Jeffrey L. Lieberman, MD, introduces the phases of schizophrenic illness in relation to the concepts of progression and deterioration. Next, Dolores Malaspina, MD, reviews the neurodevelopmental and neurodegenerative components of schizophrenia. Finally, L. Fredrik Jarskog, MD, focuses on the neuroprotective aspects of therapeutic interventions in schizophrenia.     

Humanitarian intervention and historical responsibility

Some suggest that the duty of humanitarian intervention should be discharged by states that are historically responsible for the occurrence of violence. A fundamental problem with this suggestion is that historically responsible states might be ill-suited to intervene because they are unlikely to enjoy support from the local population. Cécile Fabre has suggested a way around that problem, arguing that responsible states ought to pay for humanitarian interventions even though they ought not to take part in the military operations. We claim that Fabre’s idea is subject to two concerns. First, the duty to perform might not be appropriately transferrable from the historically responsible state to another state because it would allow the primary duty bearer to escape the worst costs of intervention. Second, an intervention might be as unlikely to generate local support when a historically responsible state pays for an intervention as when it performs it. These problems are enough to cast doubt on Fabre’s idea. However, the idea is helpful because it highlights as yet neglected questions about how the financial and material burden of humanitarian intervention is to be shared.     

Putting action memory to the test: testing affects subsequent restudy but not long-term forgetting of action events

Testing memory typically enhances subsequent re-encoding of information (“indirect” testing effect) and, as compared to restudy, it also benefits later long-term retention (“direct” testing effect). We investigated the effect of testing on subsequent restudy and 1-week retention of action events (e.g. “water the plant”). In addition, we investigated if the type of recall practice (noun-cued vs. verb-cued) moderates these testing benefits. The results showed an indirect testing effect that increased following noun-cued recall of verbs as compared to verb-cued recall of nouns. In contrast, a direct testing effect on the forgetting rate of performed actions was not reliably observed, neither for noun- nor verb-cued recall. Thus, to the extent that this study successfully dissociated direct and indirect testing-based enhancements, they seem to be differentially effective for performed actions, and may rely on partially different mechanisms.     

Antipsychotic dose modulates behavioral and neural responses to feedback during reinforcement learning in schizophrenia

Schizophrenia is characterized by an abnormal dopamine system, and dopamine blockade is the primary mechanism of antipsychotic treatment. Consistent with the known role of dopamine in reward processing, prior research has demonstrated that patients with schizophrenia exhibit impairments in reward-based learning. However, it remains unknown how treatment with antipsychotic medication impacts the behavioral and neural signatures of reinforcement learning in schizophrenia. The goal of this study was to examine whether antipsychotic medication modulates behavioral and neural responses to prediction error coding during reinforcement learning. Patients with schizophrenia completed a reinforcement learning task while undergoing functional magnetic resonance imaging. The task consisted of two separate conditions in which participants accumulated monetary gain or avoided monetary loss. Behavioral results indicated that antipsychotic medication dose was associated with altered behavioral approaches to learning, such that patients taking higher doses of medication showed increased sensitivity to negative reinforcement. Higher doses of antipsychotic medication were also associated with higher learning rates (LRs), suggesting that medication enhanced sensitivity to trial-by-trial feedback. Neuroimaging data demonstrated that antipsychotic dose was related to differences in neural signatures of feedback prediction error during the loss condition. Specifically, patients taking higher doses of medication showed attenuated prediction error responses in the striatum and the medial prefrontal cortex. These findings indicate that antipsychotic medication treatment may influence motivational processes in patients with schizophrenia.     

How crucial is the response format for the testing effect?

Combining study and test trials during learning is more beneficial for long-term retention than repeated study without testing (i.e., the testing effect). Less is known about the relative efficacy of different response formats during testing. We tested the hypothesis that overt testing (typing responses on a keyboard) during a practice phase benefits later memory more than covert testing (only pressing a button to indicate successful retrieval). In Experiment 1, three groups learned 40 word pairs either by repeatedly studying them, by studying and overtly testing them, or by studying and covertly testing them. In Experiment 2, only the two testing conditions were manipulated in a within-subjects design. In both experiments, participants received cued recall tests after a short (~19 min) and a long (1 week) retention interval. In Experiment 1, all groups performed equally well at the short retention interval. The overt testing group reliably outperformed the repeated study group after 1 week, whereas the covert testing group performed insignificantly different from both these groups. Hence, the testing effect was demonstrated for overt, but failed to show for covert testing. In Experiment 2, overtly tested items were better and more quickly retrieved than those covertly tested. Further, this does not seem to be due to any differences in retrieval effort during learning. To conclude, overt testing was more beneficial for later retention than covert testing, but the effect size was small. Possible explanations are discussed.     

Perceived Utility (not Sympathy) Mediates the Proportion Dominance Effect in Helping Decisions

The proportion dominance effect (PDE) refers to a higher motivation to help when the victims are part of a small (you can help 56 out of 60) rather than a large (you can help 56 out of 560) reference group. In two studies using different experimental paradigms, we investigated possible mediators of the PDE. Study 1 (N = 168) was conducted in three separate steps in order to test each link of the mediator model independently. Students read six vignettes where it was possible to help a fixed number of victims but where the size of the reference group was either small or large. When the reference group was small, helping motivation and perceived utility were higher, whereas sympathy toward the victims and perceived rights were not. A within‐subject mediation analysis showed that perceived utility mediated the PDE. Study 2 (N = 36) presented four versions of a single helping situation in a joint evaluation mode where the size of the reference group became gradually smaller in each version. All participants compared and responded to each version. Helping motivation increased as the reference group became smaller, and this effect was mediated by perceived utility rather than by distress, sympathy, or perceived responsibilities. Our results suggest that unlike, for example, the identifiability and singularity effects, which have been suggested to be mediated by emotional reactions, the PDE is mediated by perceived utility.

How predictions of economic behavior are affected by the socio-economic status of the target person

We investigate how the stereotype of the poor (vs. middle class) influences behavioral predictions. In Study 1, participants made predictions regarding another person’s economic behavior in scenarios pertaining to rate of time preferences (loss, gain of smaller and larger amount). We find that participants, across scenarios, expect individuals with low SES to show more short-sightedness—i.e., steeper temporal discounting. This pattern persisted until strong diagnostic information about previous economic behavior was provided. These results are novel but consistent with previous work on stereotype application. Study 2 probed stereotype accuracy. Participants with lower vs. higher SES reported how they would act in scenarios matching those of Study 1. We find that they respond very similarly, which is in contrast to the stereotype that poor people are more short-sighted and may possibly be taken to suggest that the association between low SES and short-sightedness is biased.     

Consumerism as a moral attitude

In this theoretical and explorative essay, from an analysis of Pope Francis’, Cornel West's, and William T. Cavanaugh's works, it is argued that it is possible to construe a specific understanding of the concept of consumerism within the political theological discourse. From the analysis, consumerism is imagined as a fundamental attitude of remaining morally indifferent towards suffering. Accordingly, the proposed definition for consumerism is understood as the act of trivializing the good and remaining indifferent towards suffering. Furthermore, the article highlights how this definition of consumerism challenges the idea of consumerism as an “ersatz” religion, which is an understanding of consumerism that is often used within a Christian theological context.
