The effects of feature type in operant serial feature-positive discriminations

In two experiments, rats were trained on two operant serial feature positive discriminations in which one feature was a flavored solution and the second feature was a visual or auditory cue. As in a previous study ([Goddard and Holland, 1996]), transfer of a feature’s control to the target of the other discrimination was not observed when the flavor feature and the reinforcer were flavored sucrose solutions (Experiment 1). The performance of comparison groups showed that this lack of transfer was not due to confounded differences in the event contingencies resulting from having similar stimuli serve as feature and reinforcer. By contrast, in Experiment 2, transfer was observed between visual and flavor features when the flavor feature was unsweetened and the reinforcer was plain sucrose. These results suggest that the lack of transfer in Experiment 1 and in [Goddard and Holland, 1996] study were related to the biological significance or hedonic properties of the sucrose feature.     

Knowledge and experience of time in primitive mental states2

The author proposes that time be considered an object of working through during the psychoanalysis of patients whose mental functioning reveals distinct primitive aspects. These so‐called ‘difficult patients’ are particularly intolerant of the temporal limits of analytic sessions and often attempt to undermine the analytic setting. He presents some hypotheses about time and the mind's depth levels. A series of clinical vignettes taken from the analysis of adolescent, borderline and psychotic patients shows several ways in which the analysand's perception of and relation to time surfaces and is worked through in the course of analysis. Analyzing the relationship with time and the conflict between denial and acceptance of temporality proved a significant catalyst in the development of cases that had tenaciously impeded progress. It thus became possible to bring about important changes in the ways such patients experienced affect in the analytic relationship and in object relations, not by acting directly upon these relationships but by working instead on the formal parameters that organize the mind–and primarily on its spatio‐temporal organization.     

Experiences of the health care delivery system in a rural South African setting

This exploratory study aimed to examine health care provider work-related experiences in a rural South African context. Participants were a convenient sample of 12 medical practitioners (private sector = 55%). The practitioners responded to an open-ended question on their health care delivery-related experiences. Thematic analysis of the data revealed that the medical officers experienced both care provider fatigue and satisfaction from their work roles. Experiences of care provider fatigue were characterised by stress, anxiety, hopelessness, depression, burnout, frustration, and anger. Care provider satisfaction was associated with happiness, ability to cope, security, conscience, and commitment. Job retention and satisfaction of the health care providers were dependent on material and manpower resourcing of health services.     

目标设置对非伦理行为的影响:边界条件与理论基础

作为一种有效的激励方式,目标设置被广泛地运用于各类组织中。然而,近年来一系列的研究发现,目标设置也会引发员工的非伦理行为。全面梳理了国外对于目标设置影响非伦理行为的相关研究,系统地介绍了两者的直接关系、边界条件及理论基础,在总结这些研究的基础上,提出未来研究应从拓展研究方法(基于真实组织情景下的调查)和研究内容(强化调节、中介及社会性视角下的研究)两方面展开。     

Increasing following headway with prompts, goal setting, and feedback in a driving simulator

We evaluated the effects of prompting, goal setting, and feedback on following headway of young drivers in a simulated driving environment and assessed whether changes produced in following headway were associated with reductions in hard braking when drivers were and were not using cell phones. Participants were 4 university students. During baseline, drivers spent half of the time talking on cell phones while driving. At the start of the intervention, drivers were prompted to increase following headway while on the cell phones and were provided a specific target for following headway. Drivers were given feedback on increasing following headway when on cell phones at the end of each session. The intervention package was associated with an increase in following headway and a decrease in hard braking when participants were on and off the cell phones. Cell phone use did not affect any of the measures.     

PARENTS AND THEIR CHILD AND THE ANALYST IN THE MIDDLE

The first part of this paper explains how the transgenerational mandate influences the mental activity of the child. When a child acts the denied suffering of the parental couple, the analyst risks being imprisoned by the transgenerational mandate. Frequently the analyst is unconsciously asked by the parents to cure without curing because the child's psychological birth, still in the making, threatens the defensive equilibrium of the parents. The analyst is thus caught between the parents and the child and must find his/her own way forward in order to free the child from the burden of the mandate. In the second part of the paper, an analysis of a 5-year-old child is presented. The author shows how a transgenerational mandate may hold a traumatic potential because it can impair heavily the child's capacity to think. The author also describes the way in which she works with the parents and how she manages the setting and the style of the interpretation. She insists in particular on the need to sustain the child's perceptions in order to gradually allow the child to take roots in his/her experiences and therefore develop his/her own identity.     

Temporal landmarks: proximity prevails

Subjects in conditioning experiments time their conditioned responses relative to the onsets of the conditioned stimuli (CSs). These onsets are temporal landmarks, by reference to which subjects may estimate the location of the unconditioned stimulus (US) in time. In a serial compound conditioning paradigm, a long duration CS comes on first, followed later by a second shorter CS, creating both a long-range and a short-range predictor of the US. We ask whether displacing the short-range predictor relative to the long-range predictor causes subjects to strike a compromise between the different temporal locations predicted by the two CSs. In three experiments with pigeons, we varied the training conditions so as to favor or militate against this outcome. However, in all conditions, there was no compromise; after the onset of the displaced short-range CS, the timing of conditioned responding was governed by it alone. This result contrasts with the compromises that are seen when the feeding time predicted by a CS is put in conflict with the time predicted by the circadian clock, and with the similar compromises sometimes seen when a nearby spatial landmark is displaced relative to a larger spatial context.

Evaluating public posting,goal setting,and rewards to increase physical activity during school recess

We evaluated a pedometer‐based intervention consisting of public posting between two teams of students, with additional self‐monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self‐monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal‐setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step‐total goal.     

The concept of the 50-minute hour: Time forming a frame for the unconscious

Abstract

The 50-minute hour is a feature of psychoanalytic work that is most commonly discussed in the context of case reports. This paper examines it as a concept. The author starts by describing the origin of the 50-minute hour and its development as an element of the psychoanalytic setting or framework. Next, he considers the significance of the clock as a relational factor in the session and reflects on the alienness of the time of day to the unconscious, and the consequences of this alienness. He then uses a clinical example to illustrate the phenomenon of the stretching effect of time in analytic sessions. Finally, the author demonstrates how cleverly the 50-minute hour excises the time needed for unconscious processes from our accelerated present; he shows that it challenges the social convention of time, and has a structuring effect in that it “times” psychic processes.
