Physical and conceptual priming effects on picture and word identification

In the study phase of these experiments, subjects were asked to think of an item suggested by the omission in an incomplete sentence, and then look at a picture or word describing an item and say whether it was the same as theirs. In the test phase, they were asked to identify studied and nonstudied items presented briefly in either picture or word form. Subjects were then required to recall the words or pictures shown in the study phase. Experiment 1, with a within-subjects design, revealed that the studied pictures were identified more readily than studied words and nonstudied pictures. This indicates a physical priming effect. In word identification, studied words were identified more readily than nonstudied words; however, there was no difference between studied words and studied pictures, and the performance for studied pictures and nonstudied items were largely the same. The physical priming effect on picture identification was also shown in Experiment 2, with a between-subjects design. Different processing mechanisms in picture and word identification are discussed.     

Monotone Majorizable Functionals

Several properties of monotone functionals (MF) and monotone majorizable functionals (MMF) used in the earlier work by the author and van de Pol are proved. It turns out that the terms of the simply typed lambda-calculus define MF, but adding primitive recursion, and even monotonic primitive recursion changes the situation: already Z.Z(1 — sg) is not MMF. It is proved that extensionality is not Dialectica-realizable by MMF, and a simple example of a MF which is not hereditarily majorizable is given.     

Medical Ethics Research Between Theory and Practice

The main object of criticism of present-day medical ethics is the standard view of the relationship between theory and practice. Medical ethics is more than the application of moral theories and principles, and health care is more than the domain of application of moral theories. Moral theories and principles are necessarily abstract, and therefore fail to take account of the sometimes idiosyncratic reality of clinical work and the actual experiences of practitioners. Suggestions to remedy the illnesses of contemporary medical ethics focus on re-establishing the connection between the internal and external morality of medicine. This article discusses the question how to develop a theoretical perspective on medical ethical issues that connects philosophical reflection with the everyday realities of medical practice. Four steps in a comprehensive approach of medical ethics research are distinguished: (1) examine health care contexts in order to obtain a better understanding of the internal morality of these practices; this requires empirical research; (2) analyze and interpret the external morality governing health care practices; sociological study of prevalent values, norms, and attitudes concerning medical-ethical issues is required; (3) creation of new theoretical perspectives on health care practices; Jensen's theory of healthcare practices will be useful here; (4) develop a new conception of bioethics that illuminates and clarifies the complex interaction between the internal and external morality of health care practices. Hermeneutical ethics can be helpful for integrating the experiences disclosed in the empirical ethical studies, as well as utilizing the insights gained from describing the value-contexts of health care practices. For a critical and normative perspective, hermeneutical ethics has to examine and explain the moral experiences uncovered, in order to understand what they tell us.     

频率差异假设和长时记忆的视优效应

本文包括长时记忆视优效应的三项实验。实验一使用汉语为学习材料,北京人与广东人为被试;实验二使用英语为学习材料、美国人与中国人为被试;实验三使用日语为学习材料、日本人为被试。三项实验都有视觉、听觉两种呈现方式。三项实验的结果都有利于证明频率差异假设,即如果在书面言语中经验某字词的频率高于在口语中经验该字词的频率,则该字词的视觉呈现优于听觉呈现。     

Positive Interpretation Bias Predicts Longitudinal Decreases in Social Anxiety

Theoretical models of social anxiety suggest that distorted interpretation processes contribute to its development and maintenance, although the pathways through which this occurs are not well understood. Therefore, the present longitudinal study sought to determine whether negative interpretation bias, positive interpretation bias, and interpretation inflexibility (the degree to which participants correctly revise initial interpretations) predict changes in social anxiety over time. In an important advance over prior studies, individual differences in working memory capacity (WMC) were accounted for, as WMC is thought to play a crucial role in the generation and maintenance of interpretation biases. Following a baseline assessment of social anxiety, interpretation biases, and WMC, participants completed follow-up assessments of social anxiety both 2 weeks (n = 106) and 4 weeks (n = 96) later. After controlling for baseline social anxiety and WMC, greater positive interpretation bias was found to predict lower social anxiety at both follow-ups. Neither negative interpretation bias nor interpretation inflexibility was significantly associated with follow-up social anxiety. These results provide support for greater positive interpretation bias as a facilitator of decreases in social anxiety and a potential target for clinical intervention.     

图形颜色、形状及质地表征特性的研究

记忆中的图形特征既可以按一定方式被直接储存,也可以按抽象形式存储。虽然目前尚无法确定图形特征（形状、颜色等）分别以何种方式存储,但可以肯定,图形的颜色和形状可以分开表征。那么,图形的其它特征之间是否也是可以分开表征呢？该研究中的两个实验对图形的质地与形状、质地与颜色之间表征关系进行了探讨。实验结果表明,图形的质地可以分别与形状、颜色分开表征,这一结果提示,人们在记忆图形时,可以将图形的不同特征按分离方式进行加工。同时,通过对两实验结果比较发现,图形的形状、颜色和质地的记忆难度之间存在差异,形状最易,颜色最难,质地居中。     

言语产生中的词长效应

采用图片命名方法考察言语产生中的词长效应,并进而分析语音计划的单位和序列性。选取能同时用单音节(如“羊”)和双音节(“山羊”)命名的图片作刺激材料,发现双音节命名明显慢于单音节命名,这种效应既表现在首音节型(如“花”与“花朵”),也表现在尾音节型(如“羊”与“山羊”)刺激材料上。研究结果支持语音编码从左到右、系列提取和双音节词的词音计划单位大于单音节词的观点。该文还对图片命名中的频率效应进行了事后分析。     

Attachment Relationships as Predictors of Cognitive Interpretation and Response Bias in Late Adolescence

We investigated behavioural and cognitive representations of attachment style. Specifically, we sought to test continuity in attachment style and whether participants' perceptions of their attachments to parents, peers, and romantic partners would predict cognitive interpretation and responses to 12 ambiguous situation scenarios. Participants were 161 undergraduate students (17–20 years) who completed the Parental Bonding Instrument, the Attachment Style Questionnaire and the Inventory of Parent and Peer Attachment (peer subscale). Participants then indicated whether they interpreted ambiguous situations as threatening versus non-threatening and how they would respond (proactively, aggressively, or avoidantly). Regression analyses revealed that insecure parental attachments were the main predictor of participants' interpretations and their planned responses, followed by romantic attachments. Peer attachments played little role in the predictions. These results suggest that interpretation of situations and subsequent plans of action may be influenced by attachment related experiences. We discuss our findings in terms of their relevance to attachment theory and their application to our understanding of the concepts of attachment in development of interpersonal relationships.
