Interoperation transfer in Chinese–English bilinguals’ arithmetic

We examined interoperation transfer of practice in adult Chinese-English bilinguals' memory for simple multiplication (6 × 8 = 48) and addition (6 + 8 = 14) facts. The purpose was to determine whether they possessed distinct number-fact representations in both Chinese (L1) and English (L2). Participants repeatedly practiced multiplication problems (e.g., 4 × 5 = ?), answering a subset in L1 and another subset in L2. Then separate groups answered corresponding addition problems (4 + 5 = ?) and control addition problems in either L1 (N = 24) or L2 (N = 24). The results demonstrated language-specific negative transfer of multiplication practice to corresponding addition problems. Specifically, large simple addition problems (sum > 10) presented a significant response time cost (i.e., retrieval-induced forgetting) after their multiplication counterparts were practiced in the same language, relative to practice in the other language. The results indicate that our Chinese-English bilinguals had multiplication and addition facts represented in distinct language-specific memory stores.     

Energetic Cost and Stability During Human Walking at the Preferred Stride Velocity

The possibility that preferred modes of locomotion emerge from dynamical and optimality constraints and the energetic and dynamical constraints on preferred and predicted walking frequency are explored in this article. Participants were required to walk on a treadmill at their preferred frequency, at a frequency predicted as the resonance of a hybrid pendulum-spring model of the legs, and at frequencies +/-15%, +/-25%, +/-35% of the predicted frequency. Walking at the preferred and predicted frequencies resulted in minimal metabolic costs and maximal stability of the head and joint actions. Mechanical energy conservation was constant across conditions. The head was more stable than the joints. The joints appeared to be in service of the head in maintaining a stable trajectory. The major findings of this study suggest a complementary relationship between energetic (physiological) and stability constraints in the adoption of a preferred frequency of walking. Multiple subsystems may be involved in constraining observed macroscopic behavior in intact biological systems. The approach and results of the study imply that a useful tack in understanding how dynamical control structures arise is to study the potential criteria that serve to act as constraints on skilled movement patterns in unimpaired and impaired populations.     

Intracerebroventricular Administration of Mineralocorticoid Receptor Antisense Oligonucleotides Attenuates Salt Appetite in the Rat

The anterior ventral third ventricle (AV3V) region of the brain contains high concentrations of mineralocorticoid receptors (MR) and glucocorticoid receptors (GR) that are important in the maintenance of body fluid and electrolyte balance as well as other physiological processes. Daily intracerebroventricular pulse injections of MR antisense oligonucleotides significantly suppressed deoxycorticosterone acetate (DOCA) induced salt appetite in a dose-related manner. Similar administration of GR antisense or scrambled/sense oligonucleotide into the third ventricle failed to inhibit salt appetite. Salt appetite aroused after adrenalectomy was not suppressed by MR antisense oligonucleotide treatments but was suppressed by an antisense oligonucleotide directed against the angiotensin II AT1 receptor subtype. Receptor binding analysis demonstrated that MR and GR oligonucleotide treatments each reduced their respective receptor subtypes. Finally, although GR antisense oligonucleotide treatment was ineffective in suppressing DOCA-induced salt appetite, this treatment did increase stress induced corticosterone release as well as delayed the recovery of corticosterone to basal levels after stress.     

Uprooted minds: displacement,trauma and dissociation

The author, English born and living in Sydney, Australia, presents an argument for the usefulness of the recognition of the implicit simultaneous links between the following:

• development of psychic skin and the establishment of the body schema
• development of a sense of identity
• relationship with place

such that the formulation psychic skin< > mind < > body < > self < > place < > world can be thought of as an organising gestalt or implicit continuum of ‘skin’ experience and process upon which the explicit always depends. This constitutes a taken‐for‐granted ground‐plan of the self‐in‐place . The author follows this with an exploration of the consequences for psychic health of a traumatic rupture of this gestalt for both individual and group. Material from two cases is presented: first, a young woman whose family fled the Balkan wars which splintered the former Yugoslavia; second, the transmission of displacement trauma into the third generation of a family who arrived in Australia after WW II from the former Yugoslavia. For the purposes of this paper I will not make a distinction between migrants/exiles/refugees and instead refer to either displacement or dislocation.     

The Unfreezing of Time in the Haunted Hours

When trauma shattered the cohesion of the self and “destroyed time” for my patient Bob, he managed to hold himself more or less together with the help of haunting ghosts. This paper is the story of how my connection with Bob deepened as I eventually learned to honor his ghosts through access to my own dissociated memories of traumatic loss that had left a ghostly presence in its wake. I hope to show how a difficult and complex immersion into haunted worlds—Bob’s and my own—created the possibility for new relational depths and the reemergence of Bob’s creativity.     

Revisiting a meta-analysis of helpful aspects of therapy in a community counselling service

This small scale mixed methods study examines helpful events in a community counselling setting, categorising impacts of events according to Timulak’s [(2007). Identifying core categories of client-identified impact of helpful events in psychotherapy: A qualitative meta-analysis. Psychotherapy Research, 17, 305–314] meta-synthesis of significant events research. Comparisons were made between the types of impacts reported as helpful by clients receiving cognitive behavioural therapy (CBT) or relational integrative counselling. Seventy-five clients identified 291 significant events on 216 Helpful Aspects of Therapy (HAT) forms. The findings broadly reflect all nine impacts identified by Timulak (2007). The study also suggests that a potential new category, ‘voicing’ may exist. Differences between the types of impacts reported as helpful by clients in CBT and integrative therapy showed a higher percentage of CBT clients reporting ‘behavioural change/problem solution’, ‘reassurance’ and ‘client involvement’ as helpful. Differences in other categories were not statistically significant.     

Correlates of Burnout in Inpatient Substance Abuse Treatment Therapists

Recovering substance abuse therapists had a higher sense of personal accomplishment than nonrecovering therapists. Therapists who had more social support had a greater sense of personal accomplishment. Length of service was related to greater depersonalization and greater personal accomplishment. Burnout was strongly associated with occupational stress. Personal stress was associated with depersonalization.
