A feeling of chaos can accompany many real-life events over which we have little or no control, and latent developmental needs may create tension that manifests in symptoms of depression or anxiety. Particularly at critical life transitions, conflicts may arise which have no obvious solution. From an analytic perspective, recent scientific models from the area of complexity theory can prove illuminating as analogies to Jung's archetypal view of the individuation process. Throughout life, human beings, like many complex, open systems, pass from disordered phases to more complex stages of order. This paper shows how the scientific concept of self-organization can be compared with our physical and psychological developmental processes. From embryology, the model of the 'epigenetic landscape' (C.H. Waddington) is introduced as an analogy to Jung's individuation process, with a clinical example to illustrate these parallels. The emergent nature of behaviour and development is seen from the viewpoint of the organism as a dynamical system, and Jung's concept of the archetype viewed as an emergent property of the activity of the brain/mind. 相似文献

Bouts of responding: the relation between bout rate and the rate of variable-interval reinforcement

By nose poking a lighted key, rats obtained food pellets on either a variable-interval schedule of reinforcement or a schedule that required an average of four additional responses after the end of tile variable-interval component (a tandem variable-interval variable-ratio 4 schedule). With both schedule types, the mean variable interval was varied between blocks of sessions from 16 min to 0.25 min. Total rate of key poking increased similarly as a function of the reinforcer rate for the two schedule types, but response rate was higher with than without the four-response requirement. Analysis of log survivor plots of interresponse times showed that key poking occurred in bouts. The rate of initiating bouts increased as a function of reinforcer rate but was either unaffected or was decreased by adding the four-response requirement. Within-bout response rate was insensitive to reinforcer rate and only inconsistently affected by the four-response requirement. For both kinds of schedule, the ratio of bout time to between-bout pause time was approximately a power function of reinforcer rate, with exponents above and below 1.0. 相似文献

This is a reaction to Borsboom's (2006) discussion paper on the issue that psychology takes so little notice of the modern
developments in psychometrics, in particular, latent variable methods. Contrary to Borsboom, it is argued that latent variables
are summaries of interesting data properties, that construct validation should involve studying nomological networks, that
psychological research slowly but definitely will incorporate latent variable methods, and that the role of psychometrics
in psychology is that of partner, not role model.

Three experiments investigated whether rats are sensitive to the molar properties of a variable-interval (VI) schedule with a positive relation between response rate and reinforcement rate (i.e., a VI+ schedule). In Experiment 1, rats responded faster on a variable ratio (VR) schedule than on a VI+ schedule with an equivalent feedback function. Reinforced interresponse times (IRTs) were shorter on the VR as compared to the VI+ schedule. In Experiments 2 and 3, there was no systematic difference in response rates maintained by a VI+ schedule and a VI schedule yoked in terms of reinforcement rate. This was found both when the yoking procedure was between-subject (Experiment 2) and within-subject (Experiment 3). Mean reinforced IRTs were similar on both the VI+ and yoked VI schedules, but these values were more variable on the VI+ schedule. These results provided no evidence that rats are sensitive to the feedback function relating response rate to reinforcement rate on a VI+ schedule. 相似文献

This paper develops three arguments for increasing the strength of database protection under U.S. law. First, stronger protections
would encourage private investment in database development, and private databases have many potential benefits for science
and industry. Second, stronger protections would discourage extensive use of private licenses to protect databases and would
allow for greater public control over database laws and policies. Third, stronger database protections in the U.S. would harmonize
U.S. and E.U. laws and would thus enhance international trade, commerce, and research. The U.S. should therefore follow the
European example and develop two tiers of protection for databases: 1) protection for creative databases under copyright law;
2) protection for non-creative databases through a special type of sui generis protection. In order to balance private control of data and public access to data, sui generis protections should define a “fair use” exemption that permits some unauthorized extraction of data for private, educational,
and research purposes, provided that such extraction does not adversely impact the economic value of the database. 相似文献

在存在论的意义上,《管子》中的“道”、“德”是被作为重要的哲学范畴运用的,指生命产生的根源和生命存在的内在根据,二者是一体共在的关系。《管子》的“道”、“德”论揭示了人与万物在自然本性层面上的内在一体性和生态伦理的存在论维度,启示我们生态伦理应超越人与自然的外在关系,建立于人与自然内在关系的基础上。 相似文献

This article uses the distinction between the person and the variable orientations as a frame for structuring (1) research on IPV, (2) results of this research, and (3) an agenda for future research. The main tenet of this agenda is that causes, processes, and effects of IPV are person and context specific; therefore, results that relate variables to each other are of limited value if it can be shown that the processes that take place, the meaning of the variables, the profile of the transgressors and the women who experience IPV depend on time, environment, and research design. Examples of valuable variable-oriented research are given; examples of the growing contribution made by person-oriented research are given as well. Sample theories are sketched out, for the variable-oriented, the person-oriented, and the theoretical research arenas, the need for future research is derived from inconsistencies and shortcomings in both current research and theory. Sample research questions are proposed. The contributions made by the authors of this Special Section are embedded within the discussion of research and theory of IPV. It is shown that each of the contributions is valuable within a particular segment of the research landscape. 相似文献

Frontal lobe patients reproduced a sequence of capital letters or abstract shapes. Immediate and delayed reproduction trials allowed the analysis of short- and long-term memory for time order by means of suitable Markov chain stochastic models. Patients were as proficient as healthy subjects on the immediate reproduction trial, thus showing spared encoding and short-term memory. They failed, instead, on the delayed trials with capital letters, but not with random shapes, suggesting that their long-term memory impairment did not depend on primary deficits for ordering, but on inability to benefit from the organisational strategies that improve the retention and retrieval in normal subjects. 相似文献
