The relationship between biological and psychosocial risk factors and resting‐state functional connectivity in 2‐month‐old Bangladeshi infants: A feasibility and pilot study

Childhood poverty has been associated with structural and functional alterations in the developing brain. However, poverty does not alter brain development directly, but acts through associated biological or psychosocial risk factors (e.g. malnutrition, family conflict). Yet few studies have investigated risk factors in the context of infant neurodevelopment, and none have done so in low‐resource settings such as Bangladesh, where children are exposed to multiple, severe biological and psychosocial hazards. In this feasibility and pilot study, usable resting‐state fMRI data were acquired in infants from extremely poor (n = 16) and (relatively) more affluent (n = 16) families in Dhaka, Bangladesh. Whole‐brain intrinsic functional connectivity (iFC) was estimated using bilateral seeds in the amygdala, where iFC has shown susceptibility to early life stress, and in sensory areas, which have exhibited less susceptibility to early life hazards. Biological and psychosocial risk factors were examined for associations with iFC. Three resting‐state networks were identified in within‐group brain maps: medial temporal/striatal, visual, and auditory networks. Infants from extremely poor families compared with those from more affluent families exhibited greater (i.e. less negative) iFC in precuneus for amygdala seeds; however, no group differences in iFC were observed for sensory area seeds. Height‐for‐age, a proxy for malnutrition/infection, was not associated with amygdala/precuneus iFC, whereas prenatal family conflict was positively correlated. Findings suggest that it is feasible to conduct infant fMRI studies in low‐resource settings. Challenges and practical steps for successful implementations are discussed.     

From self-reliers to expert-dependents: identifying classes based on health-related need for autonomy and need for external control among mobile users

ABSTRACT

Mobile health apps are seen as promising tools to support autonomous consumers in their quest for better health. However, individual differences in the need for autonomy and need for external control may impact the degree to which individuals perceive mobile health apps to be useful in their daily life. Using data from a representative sample of the Dutch population (N = 1,027), we applied latent class analysis to identify subtypes among mobile users based on their need for autonomy and need for external control, and to examine differences among these subtypes. We identified four subgroups: the self-reliers, confirmation-seekers, expert-dependents, and indifferents. Next to demographic differences, self-reliers and confirmation-seekers were generally more e-health literate and expressed more privacy concerns than the expert-dependents and indifferents. Our findings demonstrate that subgroups of people express different degrees of health-related need for autonomy and need for external control, which should be taken into account in online and mobile health communication efforts.     

‘Please sort these voice recordings into 2 identities’: Effects of task instructions on performance in voice sorting studies

We investigated the effects of two types of task instructions on performance on a voice sorting task by listeners who were either familiar or unfamiliar with the voices. Listeners were asked to sort 15 naturally varying stimuli from two voice identities into perceived identities. Half of the listeners sorted the recordings freely into as many identities as they perceived; the other half were forced to sort stimuli into two identities only. As reported in previous studies, unfamiliar listeners formed more clusters than familiar listeners. Listeners therefore perceived different naturally varying stimuli from the same identity as coming from different identities, while being highly accurate at telling apart the stimuli from different voices. We further show that a change in task instructions – forcing listeners to sort stimuli into two identities only – helped unfamiliar listeners to overcome this selective failure at ‘telling people together’. This improvement, however, came at the cost of an increase in errors in telling people apart. For familiar listeners, similar non-significant trends were apparent. Therefore, even when informed about correct number of identities, listeners may fail to accurately perceive identity further highlighting that voice identity perception in the context of natural within-person variability is a challenging task. We discuss our results in terms of similarities and differences to findings in the face perception literature and their importance in applied settings, such as forensic voice identification.     

Curriculum and training reform in clinical psychology: Improving the integration of science and practice

Current graduate curricula do not fully grapple with and take advantage of the dialectical interplay of science and practice that is at the core of the scientist—practitioner (Boulder) model. This article addresses factors that interfere with the realization of the Boulder model and offers suggestions for curriculum reform. It emphasizes the importance of both science and practice, as well as the merit of both nomothetic and idiographic approaches to clinical training. The article discusses how academic politics often interfere with the incorporation of empirically supported treatments or assessment methods into training programs. Even when evidence-based approaches are a part of the curriculum, the challenges continue. Because empirically supported treatments are almost always associated with treatment manuals that rely on categorically defined diagnostic categories, they may inadvertently discourage idiographic functional analyses and the appreciation of underlying change principles. In addition, in light of the fact that many, if not most, students eventually pursue applied careers and because science-based interventions and assessment methods are currently underused by clinicians in the field, it is argued that clinical training should receive more recognition in scientist—practitioner programs. Programs should be mindful of the need to prepare a certain subset of interested students for scientifically based careers in applied settings. This article also highlights the importance of educating and training students in communicating and disseminating science-based clinical psychology to nonacademic psychologists and health professionals from other disciplines.
