The role of prediction in mental processing: A process approach

Although prediction plays a prominent role in mental processing, we have only limited understanding of how the brain generates and employs predictions. This paper develops a theoretical framework in three steps. First I propose a process model that describes how predictions are produced and are linked to behavior. Subsequently I describe a generative mechanism, consisting of the selective amplification of neural dynamics in the context of boundary conditions. I hypothesize that this mechanism is active as a process engine in every mental process, and that therefore each mental process proceeds in two stages: (i) the formation of process boundary conditions; (ii) the bringing about of the process function by the operation – within the boundary conditions – of a relatively ‘blind’ generative process. Thirdly, from this hypothesis I derive a strategy for describing processes formally. The result is a multilevel framework that may also be useful for studying mental processes in general.     

When is received social support related to perceived support and well-being? When it is needed

How do perceptions of being supported relate to the amount of social support received? Received and perceived support have generally been found to be only moderately related. Previous research has however focused on the amount of support received regardless of whether it was needed. We hypothesized that a measure of support received when needed would predict perceived support and well-being better than would an unqualified measure of received support. Study 1 found that correlations between received support and perceived support measures were, on average, twice as high when received support was measured as the proportion of times support was received when needed (average r = .54) than when it was measured as the number of times support was received (average r = .28). Similar results were found for correlations between received support and mental health which rose from r = .04 to r = .31 when need for support was considered. Study 2 replicated the strong relationship between support received when needed and both perceived support and mental health. Received support measures should be adapted to take the need for support into consideration in future investigation of these relationships. Social support interventions may only be beneficial if the recipient’s support needs are not already being met.     

How will things be the next time? Self in the construction of future events among school-aged children

This study examined among school-aged children the role of the self in perceived valence changes from the past to the future. Nine- to 11-year-old children (N = 57) recalled positive and negative personal events of various situations and imagined a future personal event involving the same situation following each recall. Children’s self-knowledge was assessed in terms of self-concepts for past, present, and future selves, and self-evaluations for social and cognitive competences. Children who viewed their future selves more positively and those who evaluated their cognitive competence more positively anticipated greater upward (positive) changes and smaller downward (negative) changes in their future academic performance. Children who evaluated their social competence more positively anticipated greater upward changes in their future peer relations. Furthermore, children who anticipated greater upward changes and smaller downward changes in their personal futures exhibited greater well-being. These findings shed new light on the role of self in mental time travel.     

Acculturative stress and experiential avoidance: relations to depression,suicide, and anxiety symptoms among minority college students

Although college campuses represent strategic locations to address mental health disparity among minorities in the US, there has been strikingly little empirical work on risk processes for anxiety/depression among this population. The present investigation examined the interactive effects of acculturative stress and experiential avoidance in relation to anxiety and depressive symptoms among minority college students (n = 1,095; 78.1% female; M_age = 21.92, SD = 4.23; 15.1% African-American (non-Hispanic), 45.3% Hispanic, 32.5% Asian, and 7.1% other races/ethnicities. Results provided empirical evidence of an interaction between acculturative stress and experiential avoidance for suicidal, social anxiety, and anxious arousal symptoms among the studied sample. Inspection of the significant interactions revealed that acculturative stress was related to greater levels of suicidal symptoms, social anxiety, and anxious arousal among minority college students with higher, but not lower, levels of experiential avoidance. However, in contrast to prediction, there was no significant interaction for depressive symptoms. Together, these data provide novel empirical evidence for the clinically-relevant interplay between acculturative stress and experiential avoidance in regard to a relatively wide array of negative emotional states among minority college students.

The format of children’s mental images: Penetrability of spatial images

To investigate the format of mental images and the penetrability of mental imagery performance to top-down influences in the form of gravity information, children (4-, 6-, 8- and 10-year-olds) and adults (N = 112) performed mental rotation tasks. A linear increase in response time with rotation angle emerged at 6-years, suggesting that spatial properties are represented in children’s mental images. Moreover, 6-, 8-, and 10-year-olds, but not 4-year-olds or adults, took longer to respond to rotated stimuli pairs when gravity information was incongruent with the direction of rotation rather than congruent. Overall, findings suggest that in contrast to adults’, 6- to 10-year-olds’ mental rotation performance was penetrated by top-down information. This research (a) provides insight into the format of young children’s mental images and (b) shows that children’s mental rotation performance is penetrable by top-down influences.     

Item type,occlusion, and gender differences in mental rotation

Two experiments were conducted to examine the role of item type in mental rotation. In each experiment, participants completed two computerized mental rotation tasks, one with blocks as stimuli and one with human figures as stimuli. The tasks were formatted either as a multiple-choice psychometric test (Experiment 1) or as a same–different type task (Experiment 2). Aside from the expected replication of a decreased effect of occlusion on women's accuracy when processing human figures compared to block figures, it was hypothesized that response times would increase when processing the complex but familiar human figures, compared to the simple but unfamiliar block figures. In Experiment 1, the results relevant to occlusion were replicated. However, the presence of a speed–accuracy trade-off suggested that participants processed human figures faster but less accurately than block figures. In Experiment 2, both men and women performed faster and more accurately when processing occluded human figures than when processing nonoccluded human figures. The effect of item type, its potential link to embodied cognition, and the role of strategy selection on gender differences in mental rotation are discussed.     

Building Resilience in Families,Communities, and Organizations: A Training Program in Global Mental Health and Psychosocial Support

This article describes the Summer Institute in Global Mental Health and Psychosocial Support, a brief immersion training program for mental health, health, and allied professionals who work with populations that have endured severe adversities and trauma, such as domestic and political violence, extreme poverty, armed conflict, epidemics, and natural disasters. The course taught participants to apply collaborative and contextually sensitive approaches to enhance social connectedness and resilience in families, communities, and organizations. This article presents core training principles and vignettes which illustrate how those engaging in such interventions must: (1) work in the context of a strong and supportive organization; (2) appreciate the complexity of the systems with which they are engaging; and (3) be open to the possibilities for healing and transformation. The program utilized a combination of didactic presentations, hands‐on interactive exercises, case studies, and experiential approaches to organizational team building and staff stress management.     

Projecting the self into the future in individuals with schizophrenia: a preliminary cross-sectional study

The ability to project oneself into the future contributes to development and maintenance of a coherent sense of identity. If recent research has revealed that schizophrenia is associated with difficulties envisioning the future, little is known about patients’ future self-representations. In this study, 27 participants with schizophrenia and 26 healthy controls were asked to simulate mental representations of plausible and highly significant future events (self-defining future projections, SDFPs) that they anticipate to happen in their personal future. Main results showed that schizophrenia patients had difficulties in reflecting on the broader meaning and implications of imagined future events. In addition, and contrary to our hypothesis, a large majority of SDFPs in schizophrenia patients were positive events, including achievements, relationship, and leisure contents. Interestingly, patients and controls did not differ on the perceived probability that these events will occur in the future. Our results suggest that schizophrenia patients have an exaggerated positive perception of their future selves. Together, these findings lend support to the idea that past and future self-defining representations have both similar and distinct characteristics in schizophrenia.
