复合字母刺激心理旋转加工中的整体优先效应

采用复合字母材料结合正镜像判断任务,首次揭示了心理旋转加工中的整体优先效应。实验一延长复合字母材料的呈现时间,检验心理旋转实验常用的正/镜像判断任务中的视知觉整体优先效应;实验二将实验一的复合字母材料旋转一定角度,考察心理旋转加工中的整体优先效应。结果发现：（1）延长复合字母呈现时间后的字母正镜像判断任务中,被试判断大字母和判断小字母的时间没有显著差异,并且大小字母是否一致对大字母判断和小字母判断的影响无显著差异;（2）在排除了视知觉的整体优先效应存在的情况下,发现心理旋转加工中存在明显的整体优先效应,大字母（整体）旋转条件下的反应时显著短于小字母（局部）旋转条件下的反应时;（3）旋转角度一致性对大字母旋转和小字母旋转条件下的反应时均无显著影响,表明心理旋转的整体优先效应模式可能有别于视知觉加工的整体优先效应模式     

On Yoda,Trouble, and Transformation: The Cultural Context of Therapy and Supervision

In America, we miss the pivotal role of trouble in transformation, because our pursuit of a painless and trouble-free life aborts the process by which the psyche “gives birth” to change. As therapists, we know better: healing and growth require movement through, rather than avoidance of, troubling symptoms. Meanwhile our culture, in order to avoid facing the trouble of aging, sidelines and segregates our old people, which lets the Elder spirit waiting in each Old One wither from disuse. We do for our clients what Elders would do for the culture, carrying their accumulated weight of hope and despair, joy and sorrow, violence and peace. Eldering and therapy transform that troubling weight into “spiritual ballast,” providing the stable ground people need for the journey through life. So as therapists, we’ve been drafted, ready or not, and without our informed consent, into the role of Cultural Elder. We are midwives during the labor that births new beginnings. The supervisors among us can be seen as providing for apprentice therapists the final experience that initiates them into this crucial cultural role. In contributing to the reweaving of an unraveling world, our profession serves a function and carries a responsibility much broader than that defined by our credentials.

EMERGENT CONDITIONAL RELATIONS IN A GO/NO‐GO PROCEDURE: FIGURE—GROUND AND STIMULUS‐POSITION COMPOUND RELATIONS

Past research has demonstrated emergent conditional relations using a go/no‐go procedure with pairs of figures displayed side‐by‐side on a computer screen. The present study sought to extend applications of this procedure. In Experiment 1, we evaluated whether emergent conditional relations could be demonstrated when two‐component stimuli were displayed in figure—ground relationships—abstract figures displayed on backgrounds of different colors. Five normally capable adults participated. During training, each two‐component stimulus was presented successively. Responses emitted in the presence of some stimulus pairs (A1B1, A2B2, A3B3, B1C1, B2C2 and B3C3) were reinforced, whereas responses emitted in the presence of other pairs (A1B2, A1B3, A2B1, A2B3, A3B1, A3B2, B1C2, B1C3, B2C1, B2C3, B3C1 and B3C2) were not. During tests, new configurations (AC and CA) were presented, thus emulating structurally the matching‐to‐sample tests employed in typical equivalence studies. All participants showed emergent relations consistent with stimulus equivalence during testing. In Experiment 2, we systematically replicated the procedures with stimulus compounds consisting of four figures (A1, A2, C1 and C2) and two locations (left — B1 and right — B2). All 6 normally capable adults exhibited emergent stimulus—stimulus relations. Together, these experiments show that the go/no‐go procedure is a potentially useful alternative for studying emergent conditional relations when matching‐to‐sample is procedurally cumbersome or impossible to use.     

Social anxiety and cognitive expectancy of aversive outcome in avoidance conditioning

Fear conditioning studies have shown that social anxiety is associated with enhanced expectancy of aversive outcome. However, the relation between cognitive expectancy and social anxiety has never been tested in avoidance conditioning paradigms. We compared 48 low (LSA) and high socially anxious individuals (HSA) on subjective expectancy of aversive outcome during an avoidance conditioning task. Displays of neutral faces were coupled with an aversive outcome (US): a shout and a shock. Participants could avoid the US by pressing a correct button from a button box. First, HSA showed higher US expectancy than LSA during the initial phase of avoidance conditioning, supporting the view that socially anxious individuals have an expectancy bias when social situations are ambiguous. Second, when the avoidance response became unavailable, LSA showed lower US expectancy than HSA, suggesting that low socially anxious individuals are prone to a positive bias when perceived threat is high. A lack of such positive bias in socially anxious individuals may lead to higher susceptibility to safety behavior interpretations. Together, these findings support the role of cognitive processes in avoidance conditioning and underscore the relevance to encounter avoidance learning when studying social anxiety.     

From IF to BI

We take a fresh look at the logics of informational dependence and independence of Hintikka and Sandu and Väänänen, and their compositional semantics due to Hodges. We show how Hodges’ semantics can be seen as a special case of a general construction, which provides a context for a useful completeness theorem with respect to a wider class of models. We shed some new light on each aspect of the logic. We show that the natural propositional logic carried by the semantics is the logic of Bunched Implications due to Pym and O’Hearn, which combines intuitionistic and multiplicative connectives. This introduces several new connectives not previously considered in logics of informational dependence, but which we show play a very natural rôle, most notably intuitionistic implication. As regards the quantifiers, we show that their interpretation in the Hodges semantics is forced, in that they are the image under the general construction of the usual Tarski semantics; this implies that they are adjoints to substitution, and hence uniquely determined. As for the dependence predicate, we show that this is definable from a simpler predicate, of constancy or dependence on nothing. This makes essential use of the intuitionistic implication. The Armstrong axioms for functional dependence are then recovered as a standard set of axioms for intuitionistic implication. We also prove a full abstraction result in the style of Hodges, in which the intuitionistic implication plays a very natural rôle.

Imagining human enhancement: whose future,which rationality?

This article critically evaluates bettering human life. Because this involves lives that do not exist yet, the article investigates human eugenics and enhancement through the social prism of ‘the imaginary’ (defined ‘as a set of assumptions and concepts for thinking and speaking about human enhancement and its future direction’) [1]. “Exploring basic assumptions underlying the idea of human enhancement” investigates underlying assumptions and claims for human enhancement. Firstly, human eugenics and enhancement entangles a factual as well as a normative claim about what improvement/betterment maybe constitutive of. Secondly, claims about what a better life is, is often a future orientated claim about whether certain kinds of life that do not exist yet should ever exist. Moral images of thought are introduced and how they work to make normative judgments about lives that do not exist. This implicates the moral problem of difference, where an image of a ‘better’ life—classically expressed in eugenics as a ‘superior’ and/or ‘normal’ life—necessarily entails inferiority and/or deviance from a norm. “Moral imagination in contemporary fiction and the history of old eugenics”, introduces moral images in history of eugenics and demonstrates how examples fall foul of the problem. “The new (liberal) eugenics and the moral image of therapy” examines progress in contemporary debates, the move from authoritarian to non-authoritarian eugenics (human enhancement), and how, to some extent, this has solved the problem of difference, through liberal defence of personal choice. “The heart of the eugenic issue” suggests that personal choice in liberal non-authoritarian eugenics is not immune to basic drive behind all eugenic arguments; desire as lack which is expressed as the continual dissatisfaction of not having our future expectations met.

If and Then: A Critique of Speculative NanoEthics

Most known technology serves to ingeniously adapt the world to the physical and mental limitations of human beings. Humankind has acquired awesome power with its rather limited means. Nanotechnological capabilities further this power. On some accounts, however, nanotechnological research will contribute to a rather different kind of technological development, namely one that changes human beings so as to remove or reduce their physical and mental limitations. The prospect of this technological development has inspired a fair amount of ethical debate. Here, proponents and opponents of such visions of human enhancement are criticized alike for engaging in speculative ethics. This critique exposes a general pattern that extends to other nano-, bio-, or neuroethical debates. While it does not apply to all discussions of “enhancement technologies” it does apply to all ethical discourse that constructs and validates an incredible future which it only then proceeds to endorse or critique. This discourse violates conditions of intelligibility, squanders the scarce and valuable resource of ethical concern, and misleads by casting remote possibilities or philosophical thought-experiments as foresight about likely technical developments. In effect, it deflects consideration from the transformative technologies of the present.

情色文字与图片对大学生性倾向印象形成的启动差异

128名大学生被平均分成四个组,分别接受情色文字刺激、非情色文字刺激、情色图片刺激与非情色图片刺激,考察不同材料的情色信息会对性倾向印象形成产生怎样的启动效应。结果表明:情色文字对性倾向印象形成产生显著的正向启动效应,而情色图片对性倾向印象形成的启动没有呈现出单一方向的显著效应;男性对他人的性倾向印象形成要显著高于女性,但性别因素不对启动效应产生中介影响;接触容易令人产生性联想的情色刺激会导致个体更倾向于以性的或情色的眼光看待他人。     

边缘刺激条件下错误记忆的实验研究

随着研究的深入,研究者越来越关注错误记忆中的无意识成分。本研究试图采用边缘刺激这一方法研究错误记忆中的意识-无意识机制。结果发现,边缘刺激会引发错误记忆,但它不受刺激知觉时的意识-无意识水平限制;而且这种错误记忆-经发生便很稳定,不随测量时间间隔的延长而改变。另外。研究还发现材料这一因素往往会和其他因素交融在一起共同作用于错误记忆。
