Client perspectives and uses of psychotherapy

The present paper argues for the importance of studying user perspectives on ongoing psychotherapy. Four approaches to such studies are discussed. It is stressed that studies of user perspectives may allow us to develop a broader and more robust understanding of clients as the primary agents of their own change processes, and that if the studies focus on clients' everyday lives during the course of psychotherapy, they allow us a better understanding of how clients include their psychotherapy, give it a particular significance, fight over it, and transform it as a part of their changing everyday practice in other places than the session. the rationale and design of such a study is presented. It is a study of a small number of family therapies with the present author as a co-therapist. Some preliminary findings from this study are presented.     

Slouching Toward Policy: Lazy Bioethics and the Perils of Science Fiction

Too much contemporary bioethical discourse is weak on science, lazily citing and adopting science fiction scenarios rather than science facts in the framing of analyses and policies. We challenge bioethicists to take more seriously the role of providing informed insight into and oversight over contemporary science and its implications and applications. Bioethicists must work harder to understand the fast-changing truths and limits of basic science, and they must incorporate only appropriate and authentic science into their discourse, just as they did in the past when addressing the quandaries of clinical medicine. The field of bioethics is not so old and entrenched that its future is assured. Bioethicists must make themselves useful to society in order to deserve and retain the public's trust. They can best do this by ensuring that decision making and public policy are grounded in facts, not fictions and fantasies.     

Observation and physical practice: Coding of simple motor sequences

An experiment was conducted to determine the coordinate system used in the development of movement codes during observation and utilized on later physical practice performance of a simple spatial–temporal movement sequence. The task was to reproduce a 1.3-s spatial–temporal pattern of elbow flexions and extensions. An intermanual transfer paradigm with a retention test and two transfer tests was used: a mirror transfer test where the same pattern of muscle activation and limb joint angles was required and a nonmirror transfer test where the visual–spatial pattern of the sequence was reinstated on the transfer test. The results indicated a strong advantage for participants in the physical practice condition when transferred to the mirror condition in which the motor coordinates (e.g., pattern of muscle activation and joint angles) were reinstated relative to transfer performance when the visual–spatial coordinates were reinstated (visual and spatial location of the target waveform). The observation group, however, demonstrated an advantage when the visual–spatial coordinates were reinstated. These results demonstrate that codes based in motor coordinates can be developed relatively quickly for simple rapid movement sequences when participants are provided physical practice, but observational practice limits the system to the development of codes based in visual–spatial coordinates. Performances of control participants, who were not permitted to practise or observe the task, were quite poor on all tests.     

Visuo-haptic transfer for object recognition in children with periventricular leukomalacia and bilateral cerebral palsy

Object recognition is a complex adaptive process that can be impaired in children with neurodevelopmental disabilities. Recently, we found a significant effect of time on the development of unimodal and crossmodal recognition skills for common objects in typical children and this was a starting point for the study of visuo-haptic object recognition skills in impaired populations. In this study, we investigated unimodal visual information, unimodal haptic information and visuo-haptic information transfer in 30 children, from 4.0 to 10.11 years of age, with bilateral Periventricular Leukomalacia (PVL) and bilateral cerebral palsy. Results were matched with those of 116 controls. Participants were tested using a clinical protocol, adopted in the previous study, involving visual exploration of black-and-white photographs of common objects, haptic exploration of real objects and visuo-haptic transfer of these two types of information. Results show that in the PVL group as in controls, there is an age-dependent development of object recognition abilities for visual, haptic and visuo-haptic modalities, even if PVL children perform worse in all the three conditions, in comparison with the typical group. Furthermore, PVL children have a specific deficit both in visual and haptic information processing, that improves with age, probably thanks to everyday experience, but the visual modality shows a better and more rapid maturation, remaining more salient compared to the haptic one. However, multisensory processes partially facilitate recognition of common objects also in PVL children and this finding could be useful for planning early intervention in children with brain lesion.     

Prospective memory training in young adults enhances trained-task but not transfer-task performance

ABSTRACT

Training and transfer effects of prospective memory training have not been assessed in healthy young adults yet. The present study examined the effects of an 8-day prospective memory training programme using the Virtual Week computer game in 18–24-year-old students. Using the performance of an active control group as comparison, the study revealed a significant short-lived beneficial training-induced effect on a nearest-transfer task consisting of a different version of the trained task. No evidence was obtained for transfer effects to other tasks measuring prospective memory (near transfer), or to tasks measuring various executive functions or general intelligence (far transfer). These results were compared to those from a previous study in which an identical training and testing protocol was used in 13–15-year-old adolescents. This study did reveal some evidence of near and far transfer. The results of the two studies combined suggest a greater potential for prospective memory training to induce beneficial transfer effects in young adolescents than in young adults.     

人文关怀在消除IVF—ET患者心理压力中的作用

近年我国不少生殖医学中心在如何提高体外受精一胚胎移植（IVF—ET）治疗成功率问题上,都将注意力集中在临床用药的研究、控制性超促排卵方案的改进以及实验室条件的改善上,大多忽视IVF—ET患者心理方面的治疗。有研究表明：IVF—ET治疗的成功,不仅与患者自身的病理及生理状况有关,更与患者在治疗过程中产生的心理压力有关。因此,建议医护人员在给不孕症患者实施IVF-ET助孕治疗的全过程中,应给予患者更多人文关怀,这样不仅能够减少IVF—ET患者心理健康问题的发生,而且可以改善患者的身心状态和应对治疗能力,从而提高IVF—ET治疗成功率。     

‘Sticking to a healthy diet is easier for me when I exercise regularly’: Cognitive transfer between physical exercise and healthy nutrition

Objective: Long-term rehabilitation success depends on regular exercise and healthy nutrition. The present study introduces a new framework to explain this association on a psychosocial level. The exercise–nutrition relationship was investigated by exploring the sequential mediation of habit strength and transfer cognitions.

Design: Analyses were performed at two measurement points in time (at 12 and 18?months after rehabilitation), involving 470 medical rehabilitation patients who participated in an exercise intervention.

Main outcome measures: Patients filled in paper-pencil questionnaires assessing exercise (t1) and habit strength, transfer cognitions and healthy nutrition at follow-up (t2).

Results: Habit strength and transfer cognitions mediated the relationship between exercise and nutrition.

Conclusion: Findings suggest that habit strength and transfer cognitions are important factors underlying the relationship between exercise and nutrition.     

Is more similar,better? Interacting effect of the cognitive‐style congruency and tacitness of knowledge on knowledge transfer in the mentor–protégé dyad

This study explored the effects of cognitive‐style congruency on knowledge transfer in the mentor–protégé dyadic relationship and the moderating effect of tacitness of knowledge in this relationship. Using data from 148 sales personnel dyads, we found that the more congruent the cognitive style between a mentor and a protégé, the more effective the knowledge transfer between them. Moreover, the tacitness of knowledge moderated this association as expected. When the knowledge to be transferred was organized, systematic, and clear, this positive relationship was weakened. This relationship was particularly strong when the knowledge to be transferred was tacit, ambiguous, and unclear.
