Notes for a dialogue between psychoanalysis and neuroscience1

The author postulates that the dialogue between psychoanalysis and neuroscience is based on the assumption that both deal with virtual structures. They are two facets of the same noumenal reality, but with different phenomenal realities, and it is possible to use metapsychology as a lingua franca to develop communication between the two fi elds. In the second part of the paper, the author refl ects on the results of recent neurophysiological research which seem to offer to psychoanalysis possibilities for fi nding an anatomical‐physiological correlate of some well‐known psychic phenomena and mechanisms, such as imitation, introjection, identifi cation, empathy, identity, mother‐child communication, learning, social communication and the analyst‐patient relationship. Particular neurons, called mirror neurons, have been located in the F5 area of baboons' brains. They are also present in man's brain within Broca's area. These neurons activate our motor system during both the performance of actions and the observation of actions performed by others giving rise to an automatic response, a sort of simulation or, rather, imitation, as the process is not intentional, but automatic and unaware, that is, unconscious.     

基于人工神经网络的一种效度凭证求取方法

针对基于统计学的效度凭证求取方法所存在的问题,提出了基于人工神经网络的效度凭证求取方法。蒙特卡罗模拟实验和对实际数据的分析表明,当测验分数和效标分数为单变量且非线性关系时,或者测验分数和效标分数为多变量时,运用神经网络方法可以比统计学方法更好地求取心理测验效度的基于和其他变量关系的凭证。     

GPCM模型项目参数估计程序的开发与研究

该文对GPCM的项目参数估计的方法进行较为深入的探讨,特别对容易混淆的参数初值计算以及项目参数分两步进行估计的原因进行了阐述。并且基于MMLE／EM算法,开发了相应的项目参数估计程序。通过大量的蒙特卡洛模拟,与国外专业软件PARSCALE比较,本程序的步骤参数估计值更好,区分度参数估计值相当,具有较好的应用价值。     

Why emotion recognition is not simulational

According to a dominant interpretation of the simulation hypothesis, in recognizing an emotion we use the same neural processes used in experiencing that emotion. This paper argues that the view is fundamentally misguided. I will examine the simulational arguments for the three basic emotions of fear, disgust, and anger and argue that the simulational account relies strongly on a narrow sense of emotion processing which hardly squares with evidence on how, in fact, emotion recognition is processed. I contend that the current body of empirical evidence suggests that emotion recognition is processed in an integrative system involving multiple cross-regional interactions in the brain, a view which squares with understanding emotion recognition as an information-rich, rather than simulational, process. In the final section, I discuss possible objections.     

Mental simulation of four visual object properties: similarities and differences as assessed by the sentence–picture verification task

In the sentence–picture verification (SPV) task, people read sentences implying the shape/size/colour/orientation of objects. They then verify whether pictured objects, which either match or mismatch the implied visual information mentioned in the sentence. Faster verification times on matching trials (match advantage) are considered supportive to the notion that readers perform mental simulations during sentence comprehension. This study advances this work by applying a within-subjects design to the SPV-task, enabling us to directly address the strength of and correlation between the match advantages for the properties shape, size, colour, and orientation. Results showed varying match advantages with colour showing the strongest effect, and no match advantage for orientation. Shape, size, and colour were significantly correlated, whereas there were no significant correlations with orientation. These findings suggest that interpretations of match advantages could benefit from a re-evaluation of mental simulation accountsby distinguishing between intrinsic (shape, size, and colour) and extrinsic (orientation) object properties.     

镜像神经元的发现及其对身心二元论的超越

镜像神经元是意大利帕尔玛大学Rizzolatti等人在恒河猴大脑腹侧运动前皮层F5区发现的一种神经元。这种神经元在猴子操作和观察同一个指向某种目标的动作时(如伸手抓食物)皆被激活,似乎这种神经元映射了其它个体的动作,因此被命名为“镜像神经元”。镜像神经元通过具身的模拟把动作的执行和动作的知觉结合在一起,把观察过程与身体运动过程相融合,克服了二元论在身心之间所设置的障碍,为人们正确认识身心关系开辟了新的视角。     

Risk behaviour and mental workload: Multimodal assessment techniques applied to motorbike riding simulation

We present data from an ongoing research project on the cognitive, emotional and neuropsychological basis of risk behaviour. The main aim of the project is to build a model of risk behaviour so that if we know certain cognitive, behavioural and emotional variables, we will be able to predict decisions made in the face of uncertainty and risk, with the final goal of designing programs for evaluating, preventing and controlling risk behaviour. The objective of the present study was to look for individual differences in hazard perception during a static riding simulation and their relationship with mental workload. We used a multidimensional methodology, including behavioural, subjective and physiological data. The behavioural measures were obtained in a static riding simulation during eight hazard situations. We evaluated whether eye activity measures correlated with cognitive workload and different types of risky behaviours. Eye movement parameters were measured using a video-based eye tracking system. We found that risk-prone individuals showed specific patterns of risky behaviours and that peak of saccadic velocity and subjective mental workload indexes were both reliable indicators of risk proneness. Mental workload was higher for participants showing attitudes to risk behaviours probably because of a lack of conscious awareness of specific cues indicating dangerous scenarios.     

EMPATHY AND THE EXTENDED MIND

I draw upon the conceptual resources of the extended mind thesis (EM) to analyze empathy and interpersonal understanding. Against the dominant mentalistic paradigm, I argue that empathy is fundamentally an extended bodily activity and that much of our social understanding happens outside of the head. First, I look at how the two dominant models of interpersonal understanding, theory theory and simulation theory, portray the cognitive link between folk psychology and empathy. Next, I challenge their internalist orthodoxy and offer an alternative "extended" characterization of empathy. In support of this characterization, I analyze some narratives of individuals with Moebius syndrome, a kind of expressive deficit resulting from bilateral facial paralysis. I conclude by discussing how a Zen Buddhist ethics of responsiveness is helpful for articulating the practical significance of an extended, body-based account of empathy.     

Does matter really matter? Computer simulations,experiments, and materiality

A number of recent discussions comparing computer simulation and traditional experimentation have focused on the significance of “materiality.” I challenge several claims emerging from this work and suggest that computer simulation studies are material experiments in a straightforward sense. After discussing some of the implications of this material status for the epistemology of computer simulation, I consider the extent to which materiality (in a particular sense) is important when it comes to making justified inferences about target systems on the basis of experimental results.
