Birth cohort changes in Chinese adolescents' mental health

In China, rapid economic growth and increasing social problems constitute two basic characteristics of contemporary social change. During the process of dramatic social change, an emerging question is how adolescents' mental health has changed across birth cohorts. The present paper reviews four studies of crosstemporal meta-analysis conducted by us. By meta-analysis of previous literature, we examined changes in mean scores on mental health measures over time (from the early 1990s to the mid-2000s). It was found that since the early 1990s, Chinese adolescents' mental health deteriorated across birth cohorts, shown in increased scores on the negative indicators of mental health (e.g. mental problems, anxiety, and depression), whereas self-esteem as a positive trait decreased. The dropping trend in Chinese adolescents' mental health could be attributed to social change, especially increasing social problems. Therefore, adequate attention must be paid to potential influences of social change on individuals' psychological development.     

Detection of a change in photorealism1

The perceived degree of photorealism is interpreted as reflecting the artificialness or naturalness of images. Natural images (real‐scene photographs) are images with high degrees of naturalness, while artificial images (e.g., paintings) are images with low degrees of naturalness. Alternatively, natural images are images with low degrees of artificialness, while artificial images are images with high degrees of artificialness. We attempted to disambiguate these two interpretations of the perception of photorealism by using a change‐blindness paradigm. Participants observed an image sequence showing a gradual transformation from a natural image to an artificial image or vice versa, and reported changes they noticed. More participants reported noticing changes in photorealism for the natural‐to‐artificial transformations than for the opposite transformations. This asymmetry indicates that disappearing naturalness was detected more readily than emerging naturalness, or alternatively, emerging artificialness was detected more readily than disappearing artificialness. The results for the control conditions showed that the emergence of visual information was detected more readily than the disappearance. These results suggest that the perception of photorealism should be considered as the perception of artificialness.     

A Business Model for Managing System Change Through Strategic Financing and Performance Indicators: A Case Study

This article describes how a system of care operated by a county government agency used a fiscal crisis as the opportunity to reform its children's system. A cross-system response to the crisis is outlined that includes a system of care framework coupled with a business model, inter-departmental collaboration and leadership, the use of strategic reinvestment strategies, and a quality improvement system that focuses on key indicators. Implementation of the system change is described with a specific focus on cross-system entry points, financing strategies that re-allocate funds from deep-end programs to community-based services, and management oversight through the use of performance indicators to monitor and support effectiveness. This article examines the results of the system change, including the diversion of youth from system penetration, the reduction in residential treatment bed days, the re-allocation of these savings to community-based services, and the outcomes of children who were diverted from residential care and served in the community. The article offers a number of recommendations for other communities contemplating system change.     

Revisiting the Obama Effect: Exposure to Obama reduces implicit prejudice

The present research experimentally evaluated whether exposure to Barack Obama, a positive counter-stereotypic exemplar, can result in a decrease in implicit anti-Black prejudice among non-Black participants. In order to undo any existing influence of exposure to Obama, we first exposed some participants to negative Black exemplars. Participants were assigned to one of three conditions where they were exposed subtly to negative Black exemplars, to negative Black exemplars and then Obama, or to neutral X's (i.e., control). Participants who were only primed with negative Black exemplars showed more implicit negativity toward Black people compared to the control group. Participants exposed to the same negative Black exemplars and then Obama showed a decrease in implicit racial bias levels compared to those in the negative exemplar only condition, providing experimental evidence that exposure to Obama can decrease implicit racial bias levels. These findings indicate that even subtle exposure to a positive, counter-stereotypic exemplar can reduce implicit prejudice.     

The association between cognitive ability across the lifespan and health literacy in old age: The Lothian Birth Cohort 1936

Three hundred and four participants in the Lothian Birth Cohort 1936 study took a validated IQ-type test at age 11 years and a battery of cognitive tests at age 70 years. Three tests of health literacy were completed at age 72 years; the Rapid Estimate of Adult Literacy in Medicine (REALM), the Test of Functional Health Literacy in Adults (S-TOFHLA), and the Newest Vital Sign (NVS). Participants who had a lower childhood IQ exhibited poorer performance on all three tests of health literacy taken in older adulthood. Relative cognitive change from age 11 to 70 and education were also important factors influencing performance on health literacy tasks, independent of childhood cognitive ability. It is important to understand the determinants of low health literacy in order to support individuals in managing their own health.     

The size coding of responses: The size of switches and the force feedback

We aimed to understand which factors have a functional role in the size coding of responses, either the size of the switches or the force required to trigger each switch. This question is of relevance because it allows a better understanding of processes underlying action coding. In each trial, participants saw a small or large object. Depending on its colour, the participants had to press one of two switches. In the “size” condition, the response device consisted of two switches of different visual size, but both required the same amount of force. In the “force-feedback” condition, the response device consisted in two switches of identical visual size, but one switch required more force than the other. We found a compatibility effect in the “size,” not in the “force-feedback” condition, supporting that the size-coding of responses would be due to the size of the switches.     

Soins pénalement ordonnés et positionnements professionnels : des pratiques au carrefour de la Santé et de la Justice

At the crossroad of Health and Justice, penally ordered care underlies professional practices, the articulation of which can turn out to be delicate. Here we tackle the relevance and practical application of these measures. For that purpose, semi-directive interviews and field observations have been conducted with probation agents, judges (who follow up the way sentences are executed) and psychologists. The professionals’ comments and experiences show the complexity of these measures, which intend to make “care” into a recidivism prevention tool. Misconceptions appear about theory, practices and interprofessional relationships. The idea of “care” as a sole medical term appears to be ineffective and calls for the creation of new practices.     

Sources of autonomy support,subjective vitality and physical activity behaviour associated with participation in a lunchtime walking intervention for physically inactive adults

ObjectivesBased on Basic Needs Theory (BNT: Deci & Ryan, 1985), this study examined longitudinal relationships between autonomy support from two sources, psychological need satisfaction, subjective vitality and self-reported physical activity during a walking intervention for physically inactive adults. We proposed that autonomy support provided via a walk leader and the overall programme would independently predict change in subjective vitality and physical activity from baseline to week 16 (post-intervention) and at four month follow-up. Further, we proposed that direct relationships among sources of autonomy support and outcomes would be mediated by autonomy, relatedness, and competence need satisfaction.DesignA longitudinal examination.MethodsParticipants (N = 69; n = 63 females, n = 6 males) from a 16-week walking programme completed a multi-section questionnaire measuring the aforementioned variables at three time points, including a four month post-intervention follow-up.ResultsBoth hypotheses were partly supported. Autonomy support from the walk leader positively predicted changes in subjective vitality from baseline to week 16 and in physical activity from baseline to follow-up. Autonomy support from the programme positively predicted changes in subjective vitality from baseline to week 16. Finally, autonomy gained from the walk leader mediated the relationship between autonomy support and subjective vitality, and between perceived autonomy support and physical activity.ConclusionsFindings indicate that autonomy support from both a walk leader and wider programme can predict psychological need satisfaction, subjective vitality and physical activity. Clinicians and researchers implementing future walking interventions may increase physical activity and subjective vitality by facilitating psychological need satisfaction through autonomy support from both sources.
