Effects of barbiturates and other sedative hypnotics in pigeons trained to discriminate phencyclidine from saline.

Pigeons were trained to peck the center key (lighted white) of three response keys to turn off the center keylight and to light one of the side keys with a red keylight and the other side key with a green keylight. Five responses (fixed-ratio component) on either side key relighted the center key. Food was delivered following 10 fixed-ratio components on the red key if 1.5 mg/kg phencyclidine had been given before the session. The position of the red and green keylights on the side keys varied randomly each time they were lighted by a peck on the center key. Subsequently, increasing doses of phencyclidine, barbital, amobarbital, phenobarbital, methaqualone, methyprylon, diazepam, oxazepam, and d-amphetamine were substituted for the training dose of phencyclidine, using a cumulative dosing procedure. At low doses of the sedative hypnotics, birds pecked the keylight color associated with saline. At higher doses, birds pecked both key colors. At the highest doses of pentobarbital and amobarbital, some birds responded almost exclusively On he color associated with phencyclidine. When responding on keys of both colors occurred following administration of phencyclidine or other sedative hypnotics, this responding was controlled by key position rather than by key color.     

Archetypal defenses in the clinical situation: a vignette

Critical moments along the path of an analysis are presented in order to illustrate how dreams portray archaic and typical (archetypal) defenses against the re-experience of unbearable affect as it emerges. Inner defensive 'objects' functioning as a 'self-care system' threaten to uproot, kill or destroy the connections between the dream ego and various images of vulnerability as these emerge in response to healing life events or transference feelings. Over a series of dreams, transformations within this self-care system are observed, ending in a final healing dream which marks the patient's achievement of a 'depressive position' in relation to her otherwise persecutory anxieties.     

定量运动负荷和个性特征对动觉准确性和动作稳定性的影响

目的在于了解个性特征和定量运动负荷与同射箭运动员技术水平密切相关的肘关节动觉方位准确性和手动作稳定性的关系。研究结果表明：个性特征对肘关节动觉方位准确性和手动作稳定性的影响不显著;定量运动负荷可以使肘关节动觉方位准确性明显提高,而手动作稳定性变化不显著。本研究初步证明了韩国射箭训练中利用跑步等手段使运动员处于较高心率之下进行射准练习的方法是实用有效的。     

儿童期虐待与成年后孤独感的关系:反刍思维与核心自我评价的中介作用

为考察儿童期虐待对成年后孤独感的影响机制,本研究基于反应风格理论和依恋理论,使用问卷随机调查了811名大学生。结果显示:(1)反刍思维在儿童期虐待与孤独感之间有显著中介作用;(2)核心自我评价在儿童期虐待对孤独感的影响中起显著中介作用;(3)核心自我评价与反刍思维在儿童期虐待与孤独感之间起显著连续中介作用。本研究的结果有助于揭示儿童期虐待对孤独感的影响机制,对抑制儿童期虐待的消极后果具有重要的启示意义。     

大学生智能手机成瘾与抑制控制能力的关系:手机位置和认知负荷的调节作用

本研究以66名大学生为被试,采用Flanker效应和工作记忆的双任务设计来探讨手机位置、认知负荷在智能手机成瘾与抑制控制能力之间的调节作用。结果发现：（1）在低认知负荷下,无论是否智能手机成瘾,手机存在视线之外比手机在视线之内时抑制控制能力更差;（2）在高认知负荷下,智能手机成瘾与手机位置交互作用显著：当手机在视线之内时,智能手机成瘾者的抑制控制能力显著差于非成瘾者;而当手机在视线之外时,两者没有显著差异。结果表明,智能手机成瘾大学生的抑制控制能力不仅会受到手机位置的影响,还会受到任务本身所带来的认知负荷的调节。     

Does late preterm birth impact trunk control and early reaching behavior?

The aims of the study were to 1) verify the level of trunk control longitudinally and reaching behavior while sitting in two positions in late preterm (LPT) and full-term (FT) infants, 2) determine whether the level of trunk control relates to reaching outcomes. Twenty LPT infants and 36 infants born FT were assessed via three in-lab visits: at 6, 7, and 8 months. At each visit, the Segmental Assessment of Trunk Control (SATCo) and reaching assessment were performed, where the infants were positioned sitting in the ring and at 90° of flexion of hips, knees, and ankles. Accurate manual support to the trunk was provided in each visit. LPT infants presented a lower level of trunk control over time. LPT infants presented a higher percentage of unimanual reaches and successful grasping at 7 months' visit, and a higher number of reaches at 8 months' visit compared to FT infants. The sitting positions did not influence reaching performance. The level of trunk control relates to functional reaching strategies only in FT infants. This study might provide insights for clinicians for understanding the level of trunk control, the importance of reaching behaviors for exploration, and considering these behaviors as strategies for intervention.     

Editorial

This paper is a response to William Meredith-Owen’s paper presented at the inaugural joint conference on ‘Alchemy, a bridge to Jung’s objective psyche’, for The Society of Analytical Psychology and the West Midlands Institute of Psychotherapy in autumn 2020. The paper presents a way of understanding the collective unconscious through the functioning of the core self, and thus offers a bridge which addresses the indivisibility of the personal and collective psyche/unconscious, referencing Mary Williams’ (1963) classic paper. Specifically, this is applied to Winnicott’s dream of destruction that he had after reviewing Memories, Dreams, Reflections, as well as to parts of the psyche that were dissociated due to significant early deprivation – the primary narcissistic wounds. Alchemical metaphors are shown to relate to the analytic process, which allows the primitive core self (with its identificatory, participatory, connecting nature), when integrated through relationship, to sink back into the unconscious and function as the Self.     

The effect of state core self-evaluations on task performance,organizational citizenship behaviour,and counterproductive work behaviour

Although the personality–performance relationship has been studied extensively, most studies focused on the relationship between between-person differences in the Big Five personality dimensions and between-person differences in job performance. The current paper extends this research in two ways. First, we build on core self-evaluations (CSEs): an alternative, broad personality dimension that has proven to be a good predictor of job performance. Second, we tested concurrent and lagged within-person relationships between CSEs and task performance, organizational citizenship behaviour (OCB), and counterproductive work behaviour (CWB). To this end, we conducted two experience sampling studies; the first one assessing the relationship between state CSEs and levels of momentary task performance and OCB, and a second study in which employees reported on their level of state CSEs and momentary CWB. Results showed that there is substantial within-person variability in CSEs and that these within-person fluctuations relate to within-person variation in task performance, OCB, and CWB towards the organization, and CWB towards the individual. Moreover, CSEs prospectively predicted within-person differences in task performance and CWB towards the organization, whereas the reversed effect did not hold. These findings tentatively suggest that state CSEs predict performance, rather than the other way around.
