Self-organizing individual differences in brain development

Brain development is self-organizing in that the unique structure of each brain evolves in unpredictable ways through recursive modifications of synaptic networks. In this article, I review mechanisms of neural change in real time and over development, and I argue that change at each of these time scales embodies principles of self-organizing systems. I demonstrate how corticolimbic configurations that emerge within occasions lay down synaptic structure across occasions, giving rise to individual trajectories that become entrenched with age. Emotions have a powerful influence on this process.This is because the neural processes mediating emotion consolidate patterns of activation across the brain, through their enhancement of inter-regional coordination in real time and their contribution to synaptic shaping over development. The loss of corticolimbic plasticity with age is an unfortunate fact of development, but it is compensated in part by transitional phases and individual learning experiences through which habits are modified or replaced. I emphasize variations in inter-systemic coupling as a key mediator of developing individual differences, and I discuss the acquisition of anxious/depressive appraisals as an example.     

Crib death: a biobehavioral phenomenon?

In developed countries, more children under 1 year of age die of crib death (sudden infant death syndrome, SIDS) than of all other causes combined. Researchers and clinicians have proposed many possible causes of SIDS, but the abrupt, unexpected death of some babies remains mysterious and frightening. Although infant behavior may explain some of these deaths, scant attention has addressed behavioral characteristics of babies who die without medical explanation. Any explanation of SIDS must account for the fact that most SIDS deaths occur at 2 to 5 months of age, acknowledging that a protective mechanism appears to spare babies before 2 months but then disappears. The respiratory occlusion reflex serves as an initial defense against smothering and can provide such an explanation. Infantile reflexes wane, after providing opportunities for learned responses to be acquired. During this well-documented neurobehavioral transition from subcortical to cortically mediated responding, some babies, viable for the first 2 months, may become especially vulnerable if they fail to acquire sufficiently strong defensive behaviors needed to prevent occlusion after the waning of the life-preserving reflex. Recent success of back-to-sleep directives, urging that babies sleep on their backs to avoid smothering, supports this hypothesis.     

Prozac and the Post-human Politics of Cyborgs

Working through the lens of Donna Haraway's cyborg theory and directed at the example of Prozac, I address the dramatic rise of new technoscience in medicine and psychiatry. Haraway's cyborg theory insists on a conceptualization and a politics of technoscience that does not rely on universal “Truths” or universal “Goods” and does not attempt to return to the “pure” or the “natural.” Instead, Haraway helps us mix politics, ethics, and aesthetics with science and scientific recommendations, and she helps us understand that (without recourse to universal truth or universal good) questions of legitimacy in science come down to local questions of effect and inclusion. What, in the case of my example, are the effects of Prozac? And for whom? Who is included and empowered to create legitimate psychiatric knowledge? Who is excluded and why? And, what political strategies will increase the democratic health of psychiatric science and practice?     

Adolescents least able to cope: How do they respond to their stresses?

This paper reports the coping strategies characterising self-professed weak copers. In order to do so it examines strategies reported by a subset of a sample of 976 adolescents, as measured by the Adolescent Coping Scale. What is of interest in this investigation are the coping strategies of the most vulnerable adolescent group. Such information would be of great value to those in the helping professions working with adolescents. The results indicate that the least able copers used, at least sometimes, non-productive strategies such as tension reduction, self-blame, ignore, keep to self and, most noticeably, worry and wishful thinking. However, a range of productive strategies was also used at least sometimes, including problem-solving, working hard and focusing on the positive. The implications of these findings for turning poor copers into good copers is discussed.     

Solution‐Focused Counseling and Motivational Interviewing: A Consideration of Confluence

Solution‐focused counseling (SFC) and motivational interviewing (MI) have gained recognition over the past 2 decades. A review of the features of these counseling approaches is provided, as well as an examination of the similarities and differences on several dimensions of counseling. Attention is given to empirical research, and it is proposed that SFC and MI be considered concurrently, which appears consistent with calls in the literature for theoretical integration. A case study is included.

Instructions to mimic improve facial emotion recognition in people with sub-clinical autism traits

People tend to mimic the facial expression of others. It has been suggested that this helps provide social glue between affiliated people but it could also aid recognition of emotions through embodied cognition. The degree of facial mimicry, however, varies between individuals and is limited in people with autism spectrum conditions (ASC). The present study sought to investigate the effect of promoting facial mimicry during a facial-emotion-recognition test. In two experiments, participants without an ASC diagnosis had their autism quotient (AQ) measured. Following a baseline test, they did an emotion-recognition test again but half of the participants were asked to mimic the target face they saw prior to making their responses. Mimicry improved emotion recognition, and further analysis revealed that the largest improvement was for participants who had higher scores on the autism traits. In fact, recognition performance was best overall for people who had high AQ scores but also received the instruction to mimic. Implications for people with ASC are explored.
