情绪和控制幻觉对投资者羊群行为的影响

本研究采用双因素被试间实验具体考察了特定情绪和控制幻觉对于个体投资者羊群行为的影响,结果发现存在显著的主效应和交互作用。愉悦情绪与投资者的追涨羊群行为呈正向关系,恐惧情绪与跟跌羊群行为呈正向关系;控制幻觉与投资者的追涨羊群行为呈正向关系,与跟跌羊群行为呈负向关系;高控制幻觉的投资者在愉悦情绪下倾向于乐观追涨,而低控制幻觉的投资者在恐惧情绪下倾向于悲观跟跌。     

The influence of beverage type on aggression in males in the natural setting

Laboratory research has shown that alcohol and aggression are related and that the consumption of distilled as opposed to brewed beverages results in more aggression. A field experiment was conducted in which confederates approached 38 males who had been drinking only brewed or only distilled beverages, and asked them four annoying questions. Responses were recorded, transcribed and rated using a rank ordered scoring method. Results confirmed the prediction of more aggressive responses from the distilled beverage consuming group but findings failed to show a dose effect. The results demonstrate the viability and value of field research in this area and help to elucidate the role of alcohol in aggression.     

Intelligent vector field visualization based on line integral convolution

In order to reflect the internal motion characteristics of entire vector fields, texture visualization methods based on line integral convolution are usually adopted. However, the visualization results obtained in this way have low image quality. To solve this problem, this paper suggests using line integral convolution to optimize two specific aspects - texture enhancement and color enhancement – to provide an enhanced vector field visualization model. Existing texture enhancement algorithms can create texture aliasing. Based on an analysis of the relationship between vector angles, sampling distance and texture aliasing, the paper puts forward a texture enhancement algorithm that uses the vector angle to adjust the sampling distance of a high-pass filter. This greatly reduces the presence of texture aliasing. For color enhancement, a linear algorithm is usually used that adds vector size information to the vector field. However, the resulting image has a problem of color concentration. In view of this, the distribution characteristics of the vector field are analyzed using a histogram and a dynamic nonlinear color enhancement algorithm is proposed. This noticeably improves the color distribution of the resulting image and improves the overall visual quality of the result.     

Braving the erotic field in the treatment of adolescents*

Abstract

The psychoanalytic literature on erotic transference and countertransference in adolescence is notably sparse, despite the centrality of the developing sexual body/mind. Erotic feelings in the consulting room with an adolescent can feel taboo, causing the analyst to avoid the immediacy of these feelings. Excessive timidity on the part of the analyst can limit the growth of the capacity for containment of sexual feelings and yield what I term ‘erotic insufficiency’ in our work with adolescents. I offer clinical material from a period of erotic transference and countertransference with a 12-year-old boy to consider these ideas. Further, I suggest that the very terms ‘erotic transference’ and ‘erotic countertransference’ can feel defensively remote and antiseptic. I suggest that ‘erotic field’ better captures the subtle, nuanced interplay of feelings.     

NEUTRALITY IN THE FIELD: ALPHA‐FUNCTION AND THE DREAMING DYAD IN PSYCHOANALYTIC PROCESS

Analysts have interpreted the concept of neutrality in a variety of ways, beginning with Strachey's use of that word to translate Freud's (1915) term, Indifferenz. In this paper, neutrality is linked to Freud's notions of free association and evenly suspended attention. A history of psychoanalytic attempts to clarify the concept are presented, with special attention to issues of ambiguity and the patient's role in the determination of neutrality. Neutrality is further elaborated in relation to the bipersonal field as described by the Barangers and contemporary field theorists. Understood in terms of the field, neutrality becomes a transpersonal concept, here conceived in terms of alpha‐function and a dreaming dyad. Two clinical examples cast in the light of a Bionian perspective are discussed to suggest an alternative understanding of analytic impasses and their relation to alpha‐function and neutrality.     

Colour,face, and visuospatial imagery abilities in low-vision individuals with visual field deficits

This study investigates to what extent visual perception integrity is necessary for visual mental imagery. Sixteen low-vision participants with severe peripheral visual field loss, 16 with severe central field loss, 6 left brain-damaged patients with right homonymous hemianopia, 6 right brain-damaged patients with left homonymous hemianopia, and 16 normally sighted controls performed perceptual and imagery tasks using colours, faces, and spatial relationships. Results showed that (a) the perceptual and mental image>ry disorders vary according to the type of visual field loss, (b) hemianopics had no more difficulties imagining spatial stimuli in their contralesional hemispace than in their ipsilesional one, and (c) the only hemianopic participant to have perceptual and mental imagery impairments suffered from attentional deficits. Results suggest that (a) visual memory is not definitively established, but rather needs perceptual practice to be maintained, and (b) that visual mental imagery may involve some of the attentional–exploratory mechanisms that are employed in visual behaviour.     

Einstellung: Still Alive and Well

Predator urine, specifically fox urine, is a noxious but harmless olfactory stimulus. The results of previous studies have shown that fox urine is aversive to rats, and that rats react to fox urine in a similar manner as to other psychostressors. In the present study, the authors further investigated the use of fox urine as an aversive or stressful stimulus, specifically examining behavior change in open-field place-preference task. Three methods of presenting the fox urine were examined. Results indicated that fox urine decreased behavior, especially locomotion, during both fox-urine presentation and during a post-fox-urine recovery session. Data suggested that (a) there were fewer ambulatory episodes and less distance was traveled during the presentation of fox urine, regardless of presentation method, and (b) there were fewer vertical movements during fox-urine presentation when a fox-urine-laced cotton ball was set in the wood shavings than when it was placed on a bare floor or in a cup. The data suggested that fox urine may be an effective but nonharmful stimulus alternative for use in avoidance tasks.     

How Task Characteristics and Social Support Relate to Managerial Learning: Empirical Evidence From Dutch Home Care

Researchers have revealed that managers profit most from informal and on-the-job learning. Moreover, research has shown that task characteristics and social support affect informal learning. On the basis of these insights, the authors examined the effects of task characteristics (psychological job demands, job control) and social support from the supervisor and colleagues on informal on-the-job learning among 1,588 managers in the Dutch home-care sector. A regression analysis revealed that high demands, high control, and high colleague and supervisor support were each associated with high levels of informal learning. The authors found no evidence for statistical interactions among the effects of these concepts. They concluded that to promote managers' informal workplace learning, employers should especially increase job control.     

The fifth field of Ervin Laszlo

Increasingly gaining the attention of evolution theorists and other scientists is the new quantum‐vacuum‐interactive, or QVI‐field theory of Ervin Laszlo. Among other prospective advancements, this theory would add a fifth primary field to the four already identified by physics to account for the existence of the universe and our lives within it. As the physics and other matters involved make this new theory difficult for those other than physicists to understand, this account is written to provide a guide for the generalist and lay person.
