A psychophysiological model of emotion space

Despite a wide variety of emotions that can be subjectively experienced, the emotion space has consistently revealed a low dimensionality. The search for corresponding somato-visceral response patterns has been only moderately successful. The authors suggest a solution based on an assumed parallelism between emotion coding and color coding. According to the color detection model proposed by Sokolov and co-workers, neurons responsible for color detection are triggered by a combination of excitations in a limited number of input cells. Similarly, a limited number of input channels may feed complex emotion detectors being located on a hypersphere in a four-dimensional emotion space, the three angles of which correspond to emotional tone, intensity, and saturation, in parallel to hue, lightness, and saturation in color perception. The existence of such a four-dimensional emotion space in the subjective domain is shown by using schematic facial expressions as stimuli. A neurophysiological model is provided in which reticular, hypothalamic, and limbic structures constitute input channels of an emotion detecting system, thus acting as the first layer of emotion predetectors. Hypothalamic neurons with differential sensitivity for various transmitters may elicit a subsequent selective activation in a second layer of predetectors at the thalamic level. The latter are suggested to trigger emotion detectors located in cortical areas, the action of which should be revealed by measures of central nervous system activity. Preliminary results from evoked potential studies show that switching between schematic faces that express different emotions may be used as an objective measure for establishing a psychophysiological emotion space.     

Deterministic Chaos and Computational Complexity: the Case of Methodological Complexity Reductions

Some problems rarely discussed in traditional philosophy of science are mentioned: The empirical sciences using mathematico-quantitative theoretical models are frequently confronted with several types of computational problems posing primarily methodological limitations on explanatory and prognostic matters. Such limitations may arise from the appearances of deterministic chaos and (too) high computational complexity in general. In many cases, however, scientists circumvent such limitations by utilizing reductional approximations or complexity reductions for intractable problem formulations, thus constructing new models which are computationally tractable. Such activities are compared with reduction types (more) established in philosophy of science. This revised version was published online in August 2006 with corrections to the Cover Date.     

Change schools through revolution,not evolution

The school's traditional practices are linked to current failures and to the limited prospects of future success. The major problems with current school practices are: adopting instructional programs that have never been fieldtested and revised on the basis of data; using diagnostic practices that blame the child as being the sole cause of poor performance; using testing techniques that do not imply curricular remedies; promoting children beyond their grade-level performance; failing to provide teachers with effective training and monitoring. Recommendations for changing the system to become accountable and databased include: bringing pressure from outside the system; lobbying for alternatives to public schools; promoting intervention by the board; involving parents in union negotiations; establishing committees of expert teachers to review administrative proposals and report to the board. The central feature of the plan is to fire administrators who fail to meet attainable student-achievement goals. This practice would ensure that administrators are reinforced when children succeed, a feature that is not part of current practices.     

Is the three-term contingency trial a predictor of effective instruction?

Two experiments are reported which test the effect of increased three-term contingency trials on students' correct and incorrect math responses. Experiment 1 included two junior high school students in need of special instruction in mathematics while in Experiment 2 two other students with similar instructional needs from the same classroom were studied. In the first experiment the increased rate of presentation (3 times the baseline rate) was done without regard to whether the antecedent teacher presentations to the student were presented vocally or in written form; in the second experiment, the rates of presentation were systematically rotated across written and vocal presentations. The dependent variables were rate per minute of correct and incorrect responses of students (vocal or written). The experiments used designs incorporating features of the multiple baseline (Students A and B) and reversal (Students B, C, and D). The data showed that increasing the number of three-term trials increased correct rates while incorrect rates remained relatively low. The second experiment replicated these findings with two other students and found that the treatment effect occurred independently with vocal and written antecedents when each was isolated. The results warrant further research to test whether or not rates of presentation of three-term contingency trials are predictors of effective instruction.     

How competent are trainee and newly qualified counsellors to work with Lesbian,Gay, and Bisexual clients and what do they perceive as their most effective learning experiences?

Aim: Professional therapy organisations promote the importance of working with difference, yet subtle negative biases towards lesbian, gay, and bisexual (LGB) clients continue. Issues of competence in this area have only recently been addressed. This research aims to study the effectiveness of training to support therapists working with LGB clients in Britain. Method: Students (past and present) of an integrative counselling diploma course completed questionnaires including: background details, a Sexual Orientation Counselor Competence scale (Bidell, 2005), and two qualitative questions about previous learning relating to LGB issues. Quantitative analysis utilising a one way ANOVA test was used to compare the levels of competence at different times in training, and grounded theory to analyse the qualitative responses. Results: Results show that students have a high level of awareness, although a lower level measured in year two of the programme. The qualitative results indicate the learning value of personal experiences. Further themes describe the ways in which students learnt about LGB issues. Discussion: The reduction in scores for awareness may indicate that training facilitates a deeper understanding of self. Key themes indicate the importance of challenging old internal working models of sexual orientation. Implications for practice: The results will enable competences and effective learning experiences to be mapped in the curriculum.     

Optimal cue aggregation in the absence of criterion knowledge

The study of multi‐cue judgment investigates how decision makers aggregate cues to predict the value of a criterion variable. We consider a multi‐cue judgment task in which decision makers have prior knowledge of inter‐cue relationships but are ignorant of how the cues correlate with the criterion. In this setting, a naive judgment strategy prescribes weighting the cues equally. Although many participants are well described via an equal weighting scheme, we find that a substantial minority of participants make predictions consistent with a weighting scheme based on a low‐dimensional projection of the cue space that optimally takes into account inter‐cue correlations. The use of such a weighting scheme is consistent with minimizing maximal error in prediction when the cue‐criterion relationships are unknown.

康德论述根本恶的三重维度及其矛盾

康德在《单纯理性限度内的宗教》一书中对根本恶的论述贯穿了三种维度,即先验维度、自由维度和进步维度。但这三种维度之间并不是自恰的,而是存在着矛盾。通过对这些矛盾及康德对矛盾的解决的成败的分析可以看出,这些矛盾是内在于康德的哲学的。对（善）恶的理解只有与人的生存处境和价值追求相联系才有可能。     

Measuring the ability of transitive reasoning,using product and strategy information

Cognitive theories disagree about the processes and the number of abilities involved in transitive reasoning. This led to controversies about the influence of task characteristics on individuals' performance and the development of transitive reasoning. In this study, a computer test was constructed containing 16 transitive reasoning tasks having different characteristics with respect to presentation form, task format, and task content. Both product and strategy information were analyzed to measure the performance of 6- to 13-year-old children. Three methods (MSP, DETECT, and Improved DIMTEST) were used to determine the number of abilities involved and to test the assumptions imposed on the data by item response models. Nonparametric IRT models were used to construct a scale for transitive reasoning. Multiple regression was used to determine the influence of task characteristics on the difficulty level of the tasks. It was concluded that: (1) the qualitatively distinct abilities predicted by Piaget's theory could not be distinguished by means of different dimensions in the data structure; (2) transitive reasoning could be described by one ability, and some task characteristics influenced the difficulty of a task; and (3) strategy information provided a stronger scale than product information.
