Limits to preference and the sensitivity of choice to rate and amount of food

Studies of choice holding food‐amount ratio constant while varying food‐rate ratio within sessions showed that local changes in preference depend on relative amount of food. The present study investigated whether sensitivity of choice to food‐rate ratio and sensitivity to food‐amount ratio are independent of one another when food‐rate ratios are varied across sessions and food‐amount ratios are varied within sessions. Food deliveries for rats’ presses on the left and right levers were scheduled according to three different food‐rate ratios of 1:1, 9:1, and 1:9; each food‐rate ratio lasted for 106 sessions and was arranged independently of seven food‐amount ratios (7:1, 6:2, 5:3, 4:4, 3:5, 2:6, and 1:7 food pellets) occurring within sessions in random sequence. Each amount ratio lasted for 10 food deliveries and was separated from another by a 60‐s blackout. Sensitivity to rate ratio was high (1.0) across food deliveries. Sensitivity to amount ratio was low when food rates were equal across alternatives, but was high when rate ratio and amount ratio opposed one another. When rate ratio and amount ratio went in the same direction, choice ratio reached an elevenfold limit which reduced sensitivity to approximately zero. We conclude that three factors affect sensitivity to amount: (1) the limit to preference, (2) the equal effect on preference of amounts greater than four pellets, and (3) the absence of differential effects of switches in amount in the equal‐rates (1:1) condition. Taken together, these findings indicate that rate and amount only sometimes combine independently as additive variables to determine preference when amount ratios vary frequently within sessions.     

Clients’ experiences of dynamic interpersonal therapy (DIT): opportunities and challenges for brief,manualised psychodynamic therapy in the NHS

Dynamic interpersonal therapy (DIT) is a brief manualised psychodynamic intervention for depression. This is a first study exploring clients’ experiences of DIT specifically and brief, manualised psychodynamic psychotherapy (PP) in general. Interpretative phenomenological analysis was the methodology employed. Five participants completed a semi-structured interview, three weeks to ten months after completing DIT. The scores of pre- and post-therapy outcome measures of depression and anxiety were also available. Two emerging superordinate themes are presented here: (1) ‘The Distinct Features of DIT’, referring to how its therapeutic style and time limitations were experienced and (2) the ‘Impact of Therapy’, referring to perceived outcomes. While previous findings showed that therapist’s perceived limited activity in long-term PP was experienced as hindering/unhelpful, the perceived sense of direction in DIT appeared adequate to most participants. Secondly, the time limitations provoked complex responses. Reactions to the distinct elements of DIT are to be treated both as therapeutic opportunities and as challenges. Further, in line with psychoanalytic theory, most participants described relational changes that went beyond symptom relief and remained in progress after therapy ended. Intriguingly, there was no consistency between participants’ qualitative accounts of change and the scores of the outcome measures.     

Dynamic interpersonal therapy in an NHS tertiary level specialist psychotherapy service

We describe the introduction of dynamic interpersonal psychotherapy (DIT) into an National Health Service (NHS) tertiary psychoanalytic specialist psychotherapy service. Training in DIT began as our contribution to Improving Access to Psychological Therapies and primary care services, supporting the training and supervision of their DIT practitioners. We then discovered DIT could be a valuable treatment within our own tertiary NHS service for patients with complex presentations. Currently fighting for survival, like many NHS psychoanalytic psychotherapy services nationally, we have adopted a manual-guided, psychoanalytically based therapy to broaden our tertiary clinical psychoanalytic service and accommodate trends in mental health service provision, whilst protecting the quality and integrity of our psychotherapy. DIT helped us continue providing relevant and beneficial psychoanalytic and psychodynamic services to individual patients despite limitations of the financially challenged NHS, NICE guidelines and Payment by Results. We outline the progress and outcomes for patients with complex mental health presentations, include individual case discussion and our experience of using the DIT approach within a traditionally longer term psychoanalytic psychotherapy service.     

Co-sleeping as a proximal context for infant development: The importance of physical touch

Co-sleeping is a complex familial phenomenon that has yet to be well understood by Western scientists. This paper provides an interdisciplinary review of research from anthropology, nursing, pediatrics, sociology, social work, public health, family studies, and psychology to focus on the role of physical touch in the context of co-sleeping, and how close physical contact in this context affects infants and their caregivers. Including an anthropological, evolutionary view of co-sleeping with other perspectives highlights it as an experience-expectant proximal context for infant growth and development. From this view, the importance of physical contact and touch in the nighttime caretaking microenvironment of co-sleeping becomes a central question, rather than an artifactual byproduct of “unhealthy” sleep arrangements. Rather than trying to eliminate co-sleeping, public health messages for parents would likely benefit from a more culturally-sensitive approach that focuses on advising how to co-sleep safely for families choosing it. For families trying to retain physical closeness between parent(s) and infants in the context of modern (especially Western) infant care practices that have reduced this physical contact, co-sleeping can be an important developmental context for encouraging and engaging in sensitive and responsive caregiving and providing a context for maternal-infant physiological synchrony and regulation.     

Using Dynamic Panel Models to Study Age‐related Differences and Time‐related Changes in Personality

Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology     

Experiences of Healing Touch and Counseling on a Bereaved Population: A Grounded Theory

Grounded theory was selected as a way to develop a theory about the potential adjunctive use of energy healing in the form of healing touch (HT) along with counseling on a bereaved population. Semi-structured interviews were conducted twice with clients and once with the counselors and HT practitioners. Results indicated that the participants agreed that both counseling and HT operated well together to provide bereavement support. The themes of trust, openness, intention, and spirituality within the holistic context seemed to make this model possible. Potential ethical concerns are discussed, as well as areas for future research and clinical applications.     

The so‐called death drive,an indispensable force for any subjective life

The psychoanalytic movement has difficulty in overcoming the malaise bequeathed by what Freud wanted to call the ‘death drive’. This term remains doubly problematic: first because the indispensable antagonist of Eros‐binding cannot be reduced to a particular drive; and secondly because this Anteros plays a vital role in subjectivization. The Freudian idea of the ‘death drive’ has in addition the drawback of confusing dissociative thrust (unbinding) with the aggressive component of libidinal cathexis. Now it is precisely the lack of articulation between them that leads to deconstructing it. For it is constantly observed that in the psychic register aggression is much more fixing than unbinding. The essential role of Anteros/unbinding in the process of subjectivization can be illustrated through several key operations in subjective development: sublimatory activity and its renunciation of pleasure‐discharge, the work of mourning opposed to melancholic fixation, the intricating‐unbinding parental function, and finally the psychoanalytic treatment and its work of analysis. This means we should cease to anathematize the dynamic component of unbinding as ‘of death’ and seek to explain the concept of subjectivization better.     

Is There a Correlation Between Static and Dynamic Postural Balance Among Young Male and Female Dancers?

Aimed to investigate whether young male and female dancers have different patterns of association between static and dynamic postural balance (PB), 60 dancers from the Australian Ballet School (14–19 years old) were tested for static and dynamic PB with head and lumbar accelerometers. Monotonic relationships between static and dynamic PB were found in head movements among young female dancers in all three directions, but were found for young male dancers in the mediolateral (ML) and anteroposterior (AP) directions only. In lumbar movements, monotonic relationships were found for young female dancers in the AP direction only. Comparing head with lumbar movements in static PB, young male dancers demonstrated monotonic relationships between head and lumbar movements in all 3 directions; however, young female dancers demonstrated monotonic relationships in the AP direction only. In the dynamic measurements, both male and female dancers demonstrated monotonic relationships between head and lumbar movements for all parameters measured in the ML and vertical directions (p < .05). In conclusions, among female dancers static PB ability is correlated with their dynamic ability, whereas among male dancers, no relationship between the static and dynamic PB in the AP direction exists. Male dancers showed head and lumbar coordination in the static PB movement, but both genders manifested no head and lumbar coordination in the AP direction measured for dynamic PB.     

Reduced effects of pictorial distinctiveness on false memory following dynamic visual noise

High levels of false recognition for non-presented items typically occur following exposure to lists of associated words. These false recognition effects can be reduced by making the studied items more distinctive by the presentation of pictures during encoding. One explanation of this is that during recognition, participants expect or attempt to retrieve distinctive pictorial information in order to evaluate the study status of the test item. If this involves the retrieval and use of visual imagery, then interfering with imagery processing should reduce the effectiveness of pictorial information in false memory reduction. In the current experiment, visual-imagery processing was disrupted at retrieval by the use of dynamic visual noise (DVN). It was found that effects of DVN dissociated true from false memory. Memory for studied words was not influenced by the presence of an interfering noise field. However, false memory was increased and the effects of picture-induced distinctiveness was eliminated. DVN also increased false recollection and remember responses to unstudied items.
