An Integrated Resilience and Ecological Model of Child Abuse (REC-Model)

Much of the theories of child abuse are developed and referenced from the West, while their applications to Chinese society are unclear. It is necessary to examine the cases in Hong Kong to acknowledge the uniqueness in perception and conceptualization of child abuse and the impact of resilience, across different cultural settings. The current study aims to advance an ecological model of child abuse for Hong Kong families by integrating resilience perspective with the ecological systems, namely An Integrated Resilience and Ecological Model of Child Abuse (REC-Model), and to examine the interactions between resilience and risk factors among chronosystemic, microsystemic, marcosystemic, and ontogenic systems on child abuse. Using a cross sectional survey research method and path analysis, 565 families with children studying at ages between 9 and 13 participated and returned self-administered questionnaires in the study. The results showed that Chinese cultural parenting values moderated the influences of risk factors on child abuse, while forgiveness buffered the negative impact of microsystemic factors on child abuse. To prevent child abuse, it is important to decrease the detrimental effects of childhood abuse experiences, reduce marital conflicts, and avoid developing insecure parent-child attachment. Promoting forgiveness, while reducing parents’ rigidity of certain Chinese cultural parenting values, may also help decrease child abuse.     

Patterns of stability in adult attachment: an empirical test of two models of continuity and change

One of the core assumptions of attachment theory is that attachment representations are stable over time. Unfortunately, the data on attachment stability have been ambiguous, and as a result, alternative theoretical perspectives have evolved to explain them. The objective of the present research was to evaluate alternative models of stability by studying adults in 2 intensive longitudinal investigations. Specifically, we assessed attachment representations in 1 sample (N = 203) daily over a 30-day period and in the other sample (N = 388) weekly over a year. Analyses show that the patterns of stability that exist in adult attachment are most consistent with a prototype model--a model assuming that there is a stable factor underlying temporary variations in attachment. Moreover, although the Big Five personality traits exhibited a pattern of stability that was similar to that of attachment, they did not account for the stability observed in attachment.     

Cultivating a healthy neuro‐immune network: A health psychology approach

The field of psychoneuroimmunology (PNI) examines interactions among psychological and behavioral states, the brain, and the immune system. Research in PNI has elegantly documented effects of stress at multiple levels of the neuro‐immune network, with profound implications for both physical and mental health. In this review, we consider how the neuro‐immune network might be influenced by “positive” psychological and behavioral states, focusing on positive affect, eudaimonic well‐being, physical activity, and sleep. There is compelling evidence that these positive states and behaviors are associated with changes in immune activity in the body, including reductions in peripheral inflammatory processes relevant for physical health. Growing evidence from animal models also suggests effects of positive states on immune cells in the brain and the blood‐brain barrier, which then impact critical aspects of mood, cognition, and behavior. Tremendous advances are being made in our understanding of neuro‐immune dynamics; one of the central goals of this review is to highlight recent preclinical research in this area and consider how we can leverage these findings to investigate and cultivate a healthy neuro‐immune network in humans.     

Operant conditioning of an in vitro CNS-pneumostome preparation of Lymnaea

Operant conditioning of aerial respiratory behaviour and its consolidation into long-term memory in Lymnaea has been previously studied in both intact, freely moving snails and in in vitro preparations made from previously trained snails. Here, we show in previously untrained semi-intact in vitro Lymnaea preparations that aerial respiratory behaviour can also be operantly conditioned. Neither yoked control nor 'run-down' control procedures in these in vitro preparations result in an alteration of aerial respiratory behaviour. Memory in the operantly trained semi-intact preparations persists for at least 1h after training. Intracellular recordings made from RPeD1, one of the 3-CPG neurons and the neuron that initiates CPG activity; show that there are specific changes in central excitatory input to this neuron concurrent with learning and its consolidation into memory. In addition following the acquisition of learning and its consolidation into memory the ability of RPeD1 and VI/J neurons when depolarized to cause a pneumostome opening is significantly decreased. Thus, previously untrained in vitro semi-intact preparations can be used to study changes in neuronal activity in a neuron known to be both necessary for the behaviour and for memory formation.     

Identifying outpatients with entrenched suicidal ideation following hospitalization

The purpose of this study was to identify outpatients who experience entrenched suicidal ideation following inpatient psychiatric hospitalization. Our findings suggest that the use of a suicidal ambivalence index score was helpful at discriminating those who reported significantly greater ratings of suicidal ideation across a 1-year period of time, whereas splitting patients based upon suicide attempt history yielded nonsignificant results. Similar findings resulted from a dimensional analytic approach, as well. Application of the suicidal ambivalence index may help administrators identify patients who require more intensive clinical services to resolve their suicidal ideation.     

Effects of sleep on positive,negative and neutral valenced story and image memory

During sleep, emotional memories are preferentially strengthened. However, most studies on sleep and emotional memory focus on comparing negative valence with neutral valence stimuli. This study compared the sleep-dependent memory effects for stories and images, each comprising negative, neutral, and positive stimuli. It was hypothesized that a sleep effect would be seen for negatively and positively valenced stimuli. A novel story memory task (comprising three stories), and photographs from the Nencki Affective Picture database were presented for learning to 61 healthy adults (ages 18–25). They were tested for memory on the two tasks immediately, and then again after either a 2-hr nap (n = 31; 17 women, 14 men) or 2-hr wake period (n = 30; 13 women, 17 men). At second testing, the sleep condition had significantly better recall compared to the wake condition on both tasks. There was a relationship with valence only for the story task, with better performance for the sleep condition on the negatively and positively valenced texts, but not on the neutral text. There were no significant relationships between memory measures and sleep-stage duration and EEG power variables. The story memory findings support the hypothesis that memory consolidation prioritizes emotional memory, whether positively or negatively valenced.     

One Foot Out of the Nest: How Parents and Friends Influence Social Perceptions in Emerging Adulthood

Attachment theory proposes that representations of attachment figures are transferred between relationships, resulting in stable relational experiences. The current study used a transference paradigm to examine how parental and best friend attachment representations influence perceptions of new relationship partners in emerging adulthood. We discovered that close friendships influenced attachment anxiety and avoidance experienced specifically with friend-like others, while parental relationships affected feelings of anxiety toward a variety of people. Several relationship factors, such as the importance of the friend relationship, moderated the transference process. Our findings suggest that emerging adults’ current relationships have an impact on their reactions toward novel individuals, and emerging adults’ feelings about their existing relationship partners color their future social experiences.     

White matter maturation supports the development of reasoning ability through its influence on processing speed

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes contribute to improved reasoning ability over development. In particular, we sought to understand whether previously reported relationships between white matter microstructure and reasoning are mediated by processing speed. To this end, we analyzed diffusion tensor imaging data as well as data from standard psychometric tests of cognitive abilities from 103 individuals between the ages of 6 and 18. We used structural equation modeling to investigate the network of relationships between brain and behavior variables. Our analyses provide support for the hypothesis that white matter maturation (as indexed either by microstructural organization or volume) supports improved processing speed, which, in turn, supports improved reasoning ability.     

Attitudes towards psychotherapy manuals among clinicians treating eating disorders

Clinicians have relatively low uptake and implementation of evidence-based psychotherapies for the eating disorders, and this problem appears to be associated with low use of manualized approaches. This study examines clinicians' positive and negative attitudes to manuals, and possible beliefs and emotional factors that might drive those attitudes. The participants were 125 psychological therapists working with eating-disordered patients. Each completed standardised measures of attitudes to manuals and emotional states. A number of beliefs about the content of manuals were associated with both positive attitudes to the outcome of treatment and negative attitudes to their impact on the treatment process. In addition, a more positive mood was associated with more positive attitudes. Suggestions are made regarding how attitudes might be made more positive, in order to facilitate the use of evidence-based therapies for eating disorders.
