State-based versus reward-based motivation in younger and older adults

Recent decision-making work has focused on a distinction between a habitual, model-free neural system that is motivated toward actions that lead directly to reward and a more computationally demanding goal-directed, model-based system that is motivated toward actions that improve one’s future state. In this article, we examine how aging affects motivation toward reward-based versus state-based decision making. Participants performed tasks in which one type of option provided larger immediate rewards but the alternative type of option led to larger rewards on future trials, or improvements in state. We predicted that older adults would show a reduced preference for choices that led to improvements in state and a greater preference for choices that maximized immediate reward. We also predicted that fits from a hybrid reinforcement-learning model would indicate greater model-based strategy use in younger than in older adults. In line with these predictions, older adults selected the options that maximized reward more often than did younger adults in three of the four tasks, and modeling results suggested reduced model-based strategy use. In the task where older adults showed similar behavior to younger adults, our model-fitting results suggested that this was due to the utilization of a win-stay–lose-shift heuristic rather than a more complex model-based strategy. Additionally, within older adults, we found that model-based strategy use was positively correlated with memory measures from our neuropsychological test battery. We suggest that this shift from state-based to reward-based motivation may be due to age related declines in the neural structures needed for more computationally demanding model-based decision making.     

Quality of Family Relationships as Protective Factors of Eating Disorders: An Investigation Amongst Italian Teenagers

The study here presented aims to investigate the links between quality of family relationships and some prodromes in eating disorders. A sample of 1,083 subjects took part in the study by filling PBI, FACES and EDI questionnaires. In order to clarify the role played by family relationships in the onset of EDs, two subgroups (high risk–low risk) were individuated by using the EDI cut-offs as discriminator factors and tested separately from the main sample. The results revealed some significant relationships between the analysed dimensions. It was shown that by increasing the values from the parents’ caring style scale and the real family’s cohesiveness scale the probability for subjects to fall into the high risk group decreases. Also, by increasing the family adaptability’s values, an increase of the probability for subjects to fall into the high risk group occurs. These results support the implementation of preventive and therapeutic plans to promote health and quality of life of adolescence.     

Salience network response to changes in emotional expressions of others is heightened during early adolescence: relevance for social functioning

Adolescence is a unique developmental period when the salience of social and emotional information becomes particularly pronounced. Although this increased sensitivity to social and emotional information has frequently been considered with respect to risk behaviors and psychopathology, evidence suggests that increased adolescent sensitivity to social and emotional cues may confer advantages. For example, greater sensitivity to shifts in the emotions of others is likely to promote flexible and adaptive social behavior. In this study, a sample of 54 children and adolescents (age 8–19 years) performed a delayed match‐to‐sample task for emotional faces while undergoing fMRI scanning. Recruitment of the anterior cingulate and anterior insula when the emotion of the probe face did not match the emotion held in memory followed a quadratic developmental pattern that peaked during early adolescence. These findings indicate meaningful developmental variation in the neural mechanisms underlying sensitivity to changes in the emotional expressions. Across all participants, greater activation of this network for changes in emotional expression was associated with less social anxiety and fewer social problems. These results suggest that the heightened salience of social and emotional information during adolescence may confer important advantages for social behavior, providing sensitivity to others’ emotions that facilitates flexible social responding.     

The real thing: preschoolers prefer actual activities to pretend ones

Pretend play is a quintessential activity of early childhood, and adults supply children with many toys to encourage it. Do young children actually prefer to pretend, or do they do it because they are unable to engage in some activities for real? Here we examined, for nine different activities, American middle‐class preschoolers' preferences for pretend and real activities. The 100 children we tested (M = 58.5 months, range 36 to 82 months) overwhelmingly preferred real activities to pretend ones, and this preference increased from age 3 to age 4, then remained steady through age 6. Children provided cogent justifications for their preferences. The results are discussed with reference to other domains in which children show reality preferences and with respect to the content of preschool curricula.     

Experiences of patients undergoing repeated intravitreal anti-vascular endothelial growth factor injections for neovascular age-related macular degeneration

Current therapy to slow disease progression in patients with neovascular age-related macular degeneration (AMD) entails regular intravitreal anti-vascular endothelial growth factor (VEGF) injections, often indefinitely. Little is known about the burden imposed on patients by this repetitive treatment schedule and how this can be best managed. The aim of this study was to explore the psychosocial impact of repeated intravitreal injections on patients with neovascular AMD. Forty patients (16 males, 24 females) with neovascular AMD undergoing anti-VEGF treatment were recruited using purposive sampling from a private ophthalmology practice and public hospital in Melbourne. Patients were surveyed using the Macular Disease Treatment Satisfaction Questionnaire (MacTSQ; Bradley, Health Psychology Research Unit, Surrey, England) and underwent semi-structured, one-on-one interviews. Interview topics were: treatment burden and satisfaction; tolerability; barriers to adherence; treatment motivation; and patient education. Interviews were audio recorded and thematic analysis performed using NVivo 10 (QSR International, Doncaster, Australia). Patients recognised the importance of treatment to preserve eyesight, yet experienced significant psychosocial and practical burden from the treatment schedule. Important issues included treatment-related anxiety, financial considerations and transport burden placed on relatives or carers. Many patients were restricted to sedentary activities post-injection owing to treatment side effects. Patients prioritised treatment, often sacrificing family, travel and social commitments owing to a fear of losing eyesight if treatment was not received. Whilst anti-VEGF injections represent the current mainstay of treatment for neovascular AMD, the ongoing treatment protocol imposes significant burden on patients. An understanding of the factors that contribute to the burden of treatment may help inform strategies to lessen its impact and assist patients to better manage the challenges of treatment.

Why theatre-based research works? Psychological theories from behind the curtain

While many scholars have demonstrated the effectiveness of theatre-based knowledge mobilization, fewer studies have examined its psychological dimensions. This article examines some psychological theories that may account for the success behind theatre-based knowledge mobilization. Drawing from the Canadian Experience Project, a study about the labor market challenges of skilled immigrant workers, we show how theatre-based research dissemination efforts attempt to achieve optimal stress by using aesthetic distance processes. We maintain that this psychological capacity to attune to audience members, especially evident in forum theatre, makes theatre a particularly effective means for knowledge mobilization.     

How Therapy With Victims of Political Trauma Repairs the Third—Commentary on Gómez and Kovalskys’s Work in the Context of Postdictatorship Chile

In this discussion I use the concept of the moral Third to designate the position in which we experience the world as lawful because repair is possible. Repair takes place through acknowledgment of harming and consequent suffering. This form of acknowledgment, coupled with social recognition, is considered by the authors to be a crucial part of the therapeutic work with victims of collective trauma, especially of torture by the Pinochet security police. In relation to Gómez’s case, I discuss how the moral Third, the representation of a lawful world, is shattered by attacks on the victim’s family. Further, the witnessing function is reversed and perverted in torture, where the torturer presents a blank face and denies the very suffering he is inducing. The experience of betrayal becomes the core issue which the therapist seeks to address through the attachment relationship itself. In relation to Kovalskys’ case I consider how the moral Third of the activists, the belief in the possibility of a world in which all can live, is attacked in order to affirm the paranoid view that “only one can live.” The lived experience of this traumatizing attack is that the child becomes imbued with the sense of not deserving life, of having gained life at the expense of the other. Helping the patient to testify publicly to her personal history and truth becomes part of the healing process in the context of collective trauma.
