幼儿在辨别过程中图形维度显著性的研究

采用Triad Classification法和等级图形模式研究了4～6岁幼儿在辨别过程中图形维度显著性效应。实验1让幼儿进行自由辨别任务,发现颜色显著性强于形状,局部特征的显著性强于整体特征;随被试年龄增长,整体特征和颜色的显著性逐渐增强;对维度显著性等级模式的信息加工比对整体局部特征等级模式的加工反应时长。实验2进行按指定标准来辨别的任务,发现仍然出现图形维度显著性效应。这些结果说明图形维度显著性效应可能是自动发生的,可能比整体局部特征的认知加工更复杂。     

Self-organizing individual differences in brain development

Brain development is self-organizing in that the unique structure of each brain evolves in unpredictable ways through recursive modifications of synaptic networks. In this article, I review mechanisms of neural change in real time and over development, and I argue that change at each of these time scales embodies principles of self-organizing systems. I demonstrate how corticolimbic configurations that emerge within occasions lay down synaptic structure across occasions, giving rise to individual trajectories that become entrenched with age. Emotions have a powerful influence on this process.This is because the neural processes mediating emotion consolidate patterns of activation across the brain, through their enhancement of inter-regional coordination in real time and their contribution to synaptic shaping over development. The loss of corticolimbic plasticity with age is an unfortunate fact of development, but it is compensated in part by transitional phases and individual learning experiences through which habits are modified or replaced. I emphasize variations in inter-systemic coupling as a key mediator of developing individual differences, and I discuss the acquisition of anxious/depressive appraisals as an example.

Basic Entrenchment

In contrast to other prominent models of belief change, models based on epistemic entrenchment have up to now been applicable only in the context of very strong packages of requirements for belief revision. This paper decomposes the axiomatization of entrenchment into independent modules. Among other things it is shown how belief revision satisfying only the ‘basic’ postulates of Alchourrón, Gärdenfors and Makinson can be represented in terms of entrenchment.     

Dynamic valuation: Preference changes in the context of face-to-face negotiation

This experiment examines the dynamics of preference change in the context of face-to-face negotiation. Participants playing the role of “student” or “financial aid officer” exchanged proposals regarding the terms of a student loan. Consistent with dissonance theory, participants increased their liking for proposals they offered and/or ultimately accepted. The reactance theory prediction that participants would devalue proposals received from their opponents was confirmed for loan officers, but not for students. A pair of experimental manipulations involving the pre-rating of proposals and/or the opportunity for participants to engage in a brief discussion period prior to the initial exchange of offers mediated these effects, and influenced subsequent rates of agreement. Underlying attributional mechanisms and the implications of these findings for facilitating agreements are discussed.     

Greenpeace campaign case study — StopEsso

As some corporations begin to enjoy power and influence on a scale comparable with or even more extensive than governments, it is consumers rather than voters who are starting to hold the key to political and social change. Companies which fail to take consumer opinion into account face real threats to their brand image, and ultimately to their bottom line. This case study explores the Greenpeace‐led StopEsso campaign, detailing the campaign history, strategy and tactics, and assessing its impact so far. It shows how negative consumer perceptions of ExxonMobil (Esso), based around the issue of the company's approach to climate change, are damaging the company's interests and that the changing interactions of other key stakeholders with the company could also threaten Exxon's competitiveness. It concludes that as corporate power increases, so must corporate responsibility, for consumers are increasingly unwilling to accept dishonest or unfair behaviour, and increasingly willing to withdraw their financial support for companies which fail to respond to their expectations.

The Adult Attachment Interview and psychoanalytic outcome studies

During the last two decades, the Adult Attachment Interview (AAI) has attracted growing interest from psychoanalysts concerned with empirical research. The paper discusses the application of Crittenden's Dynamic-Maturational AAI method for assessing the outcome of psychoanalysis. The aim is to demonstrate, through a case presentation, how therapeutic change can be expressed in the AAI. The pre- and post-treatment interviews of one patient, having completed a four-times-a-week psychoanalysis, are presented. It is demonstrated that the detailed discourse analysis of the AAI, based on transcribed tape-recorded interviews, focuses subtle formal elements of language and speech reflecting dominant patterns of affect regulation and object relating. The AAI text analysis provides possibility for coding procedural memory as conveyed by the handling of the relationship to the interviewer, incorporating the dynamic relationship between researcher and subject and thus complying with a methodological prerequisite regarded by many psychoanalysts as necessary for capturing data that are relevant to psychoanalysis. On this background, the method emerges as promising for psychoanalytic outcome studies.     

Non-Prioritized Ranked Belief Change

Traditional accounts of belief change have been criticized for placing undue emphasis on the new belief provided as input. A recent proposal to address such issues is a framework for non-prioritized belief change based on default theories (Ghose and Goebel, 1998). A novel feature of this approach is the introduction of disbeliefs alongside beliefs which allows for a view of belief contraction as independently useful, instead of just being seen as an intermediate step in the process of belief revision. This approach is, however, restrictive in assuming a linear ordering of reliability on the received inputs. In this paper, we replace the linear ordering with a preference ranking on inputs from which a total preorder on inputs can be induced. This extension brings along with it the problem of dealing with inputs of equal rank. We provide a semantic solution to this problem which contains, as a special case, AGM belief change on closed theories.
