Developing research‐informed practitioners – an organisational perspective

Background: Two current trends are making it increasingly important for counsellors and psychotherapists to be more engaged with research. Evidence of effectiveness is being increasingly demanded by those who fund our therapies and also by our clients. Meanwhile therapy research is offering practicable ways for therapists to improve their practice. Therapy organisations have an opportunity, perhaps even a duty, to meet the research needs of their members. Methods: This paper reports on a survey conducted by the UK Council for Psychotherapy (UKCP) to help it plan the activities of its Research Faculty. Findings: Key findings from the survey were that the most common ways of UKCP practitioners engaging with research were through reading, discussions with colleagues and doing research. Engaging with research collaboratively with other therapists, having more time, and access to user‐friendly web‐based research resources and updates, were the factors most commonly cited as supporting practitioner engagement with research. Conversely, lack of time, difficulties accessing resources and materials and feeling not competent were the major barriers to practitioner engagement with research. Discussion: Implications for therapists, for training, and for therapy organisations are considered.     

Kinetics of diffusion via divacancies in a concentrated random fcc alloy

The diffusion kinetics in a concentrated fcc alloy are described by means of divacancies. The model chosen is the random alloy model with bound divacancies. We show that for the fcc structure the Manning formalism developed originally for monovacancies can be used intact to describe diffusion via divacancies. Monte Carlo simulation results for both tracer and collective correlation factors are in good agreement with the results of the formalism for a wide range of the component atom exchange frequencies with the divacancy except for the slower-moving component.     

Incidental encoding of numerosity in visual long-term memory

The visual system can readily extract numerosity information from brief experiences. This numerical perception is characterized by diminishing accuracy as numerosity increases, and impaired discrimination for similar quantities and large magnitudes. Here we assess whether these properties apply more broadly to numerosity in visual long-term memory. In surprise memory tests, we observed: Remarkable accuracy in estimating the number of repetitions of an exemplar image (Experiment 1a), that this accuracy decreased but remained high when estimating over categories (Experiments 1b and 1c), that numerical discrimination from memory exhibited psychophysical distance and size effects (Experiment 2), that these effects may derive from stored representations rather than post hoc approximation (Experiment 3a), and that they can reflect total elapsed experience in addition to discrete counts (Experiment 3b). Similar to how numerosity is readily extracted during visual perception, our results suggest that numerosity is encoded incidentally in visual long-term memory.     

The effects of age and set size on the fast extraction of egocentric distance

ABSTRACT

Angular direction is a source of information about the distance to floor-level objects that can be extracted from brief glimpses (near one's threshold for detection). Age and set size are two factors known to impact the viewing time needed to directionally localize an object, and these were posited to similarly govern the extraction of distance. The question here was whether viewing durations sufficient to support object detection (controlled for age and set size) would also be sufficient to support well-constrained judgments of distance. Regardless of viewing duration, distance judgments were more accurate (less biased towards underestimation) when multiple potential targets were presented, suggesting that the relative angular declinations between the objects are an additional source of useful information. Distance judgments were more precise with additional viewing time, but the benefit did not depend on set size and accuracy did not improve with longer viewing durations. The overall pattern suggests that distance can be efficiently derived from direction for floor-level objects. Controlling for age-related differences in the viewing time needed to support detection was sufficient to support distal localization but only when brief and longer glimpse trials were interspersed. Information extracted from longer glimpse trials presumably supported performance on subsequent trials when viewing time was more limited. This outcome suggests a particularly important role for prior visual experience in distance judgments for older observers.     

Spatial limits on the nonvisual self-touch illusion and the visual rubber hand illusion: Subjective experience of the illusion and proprioceptive drift

The nonvisual self-touch rubber hand paradigm elicits the compelling illusion that one is touching one’s own hand even though the two hands are not in contact. In four experiments, we investigated spatial limits of distance (15 cm, 30 cm, 45 cm, 60 cm) and alignment (0°, 90° anti-clockwise) on the nonvisual self-touch illusion and the well-known visual rubber hand illusion. Common procedures (synchronous and asynchronous stimulation administered for 60 s with the prosthetic hand at body midline) and common assessment methods were used. Subjective experience of the illusion was assessed by agreement ratings for statements on a questionnaire and time of illusion onset. The nonvisual self-touch illusion was diminished though never abolished by distance and alignment manipulations, whereas the visual rubber hand illusion was more robust against these manipulations. We assessed proprioceptive drift, and implications of a double dissociation between subjective experience of the illusion and proprioceptive drift are discussed.     

The Theory-Practice Gap in Cognitive-Behavior Therapy

This special series is devoted to understanding the theory-practice gap in cognitive-behavior therapy (CBT). Although CBT enjoys considerable empirical support, and is widely recognized as an efficacious approach to a diversity of psychiatric disorders and includes many different forms of treatment, it is unclear whether clinicians are familiar with the underlying theories of the treatments they are practicing. Moreover, it is unclear to what degree an understanding of the theory is necessary for effective practice. Gaining clarity on the role of understanding underlying theory and identifying potential disparities between theory and practice may have implications for the way graduate training programs are structured and current professionals approach continuing education. A brief exploration of these implications will be offered by introducing issues related to the scientist-practitioner model and dissemination of efficacious treatments, in addition to an outline of potential advantages and disadvantages of knowing underlying theory. This special series will then feature several major approaches to treatment wherein the role of theory and practice are discussed.     

Using Storytelling to Heal Trauma and Bridge the Cultural Divide Between Veterans and Civilians

There is a growing disconnect between the Veteran and civilian communities related to their understanding of war-related trauma, postdeployment reintegration difficulty, and the experience of Memorial Day. A therapeutic way to bridge this divide is through community storytelling. This paper describes a program development project at a Veterans Affairs Medical Center that was created to increase the connection between these communities. Using storytelling, six Veterans shared their personal experiences with a civilian audience in honor of Memorial Day. Qualitative data on the impact of the program is reported, and suggestions for future application and research are discussed.     

伦理消费者为何“言行不一”:解释水平的视角

伦理消费(Ethical consumption,EC)是指消费者在获取、使用或处置产品时考虑到个人消费行为对社会、环境或动物福祉的影响。虽然伦理消费日渐流行,但在金钱支付时伦理消费的态度却往往难以转化为实际的行为,即言行不一。本文从解释水平理论视角出发,以"心理距离→解释水平→个体反应"为分析框架展开。从时间维度上来说,在态度评价阶段和产品选择阶段两个时间点上,消费者与伦理产品的心理距离远近不同,分别激活了高低解释水平表征;高低解释水平下个体在动机和认知上又存在诸多差异,这种差异导致两个阶段的反应不同,继而出现伦理消费者态度与行为的分离。未来研究应重点关注如何根据解释水平理论有效提高伦理消费行为。     

The Reinforcing Value of Lottery Tickets,and the Synergetic Effect of Distinct Reinforcements

We present two experiments that explore the reinforcing value of lottery tickets. Participants are faced with a repeated choice task between a safe alternative and a risky prospect that provides a chance to win a lottery ticket to be played at the end of the study. Study 1 considers situations in which the risky option leads to a slightly higher expected value than the safe alternative. It shows that the risk‐taking rate increases with the probability to win the lottery ticket, but it is below 50% even when this probability is high. Study 2 shows limited sensitivity to the expected value of the risky prospect. The results can be explained with the assumption that participants rely on small samples of past experiences, and that their reaction to lottery tickets reflects large variability. The relationship between the current results and previous research on the synergetic effect of distinct reinforcements and the “pat on the back paradox” is discussed.
