Linguistics must again concentrate on the evolutionary nature of language, so that language models are more realistic with respect to human natural languages and have a greater explanatory force. Multi-agent systems are proposed as a possible route to develop such evolutionary models and an example is given of a concrete experiment in the origins and evolution of word-meaning based on a multi-agent approach. 相似文献

In the popular folklore three-score-years-and-ten is treated as a fair innings for people, and thereby serves as an informal reference point for judgements about distributive justice within a community. But length of life alone is an insufficient basis for such judgements - a person's health-related quality-of-life also needs to be taken into account. If one of the objectives of public policy is to reduce inequalities in lifetime health, it will be demonstrated that this is very likely to require systematic discrimination against the older members of a community. The notion of community solidatity will also be tested, because a decision will need to be made as to whether the same fair innings applies to all members of the community, or whether some are entitled to more than others. The strength of the fair innings principle is that it brings these issues to the fore in a systematic way which should ais their resolition in a practical context. 相似文献

Observers made forced-choice opaque/luminous responses to targets of varying luminance and varying size presented (1) on the wall of a laboratory, (2) as a disk within an annulus, and (3) embedded within a Mondrian array presented within a vision tunnel. Lightness matches were also made for nearby opaque surfaces. The results show that the threshold luminance value at which a target begins to appear self-luminous increases with its size, defined as perceived size, not retinal size. More generally, the larger the target, the more an increase in its luminance induces grayness/blackness into the surround and the less it induces luminosity into the target, and vice versa. Corresponding to this luminosity/grayness tradeoff, there appears to be an invariant: Across a wide variety of conditions, a target begins to appear luminous when its luminance is about 1.7 times that of a surface that would appear white in the same illumination. These results show that the luminosity threshold behaves like a surface lightness value—the maximum lightness value, in fact—and is subject to the same laws of anchoring (such as the area rule proposed by Li & Gilchrist, 1999) as surface lightness. 相似文献

Conventional wisdom holds that a nonpredictive peripheral cue produces a biphasic response time (RT) pattern: early facilitation at the cued location, followed by an RT delay at that location. The latter effect is called inhibition of return (IOR). In two experiments, we report that IOR occurs at a cued location far earlier than was previously thought, and that it is distinct from attentional orienting. In Experiment 1, IOR was observed early (i.e., within 50 msec) at the cued location, when the cue predicted that a detection target would occur at another location. In Experiment 2, this early IOR effect was demonstrated to occur for target detection, but not for target identification. We conclude that previous failures to observe early IOR at a cued location may have been due to attention being directed to the cued location and thus “masking” IOR. 相似文献

The hitherto widely-held assumption that the counselling interaction should be conducted face-to-face, while other activities within the overall guidance process could be supported by computer, is re-examined. Recent computer-mediated information and communications technologies are reviewed, and their implications for guidance and counselling as a whole are explored. While fears are still current that human relations will be mechanised through the use of the information and communications technologies, it is contended that human relations will be changed but not necessarily diminished. Comparisons are drawn with the ways in which open and distance learning have brought a re-examination of what is understood to be a 'real' teaching interaction. It is suggested that practitioners in the fields of guidance and counselling must similarly be prepared to manage radical change. 相似文献

This study provides a cross-sectional analysis of the relations between group self-identification and adolescent drug use in 3 samples of youth: comprehensive high-school, continuation high-school, and runaway/street youth. Youth identified with discrete groups in all 3 samples, and similar general groups were formed. In most comparisons, a high-risk group showed greater levels of drug use than did other groups. This is the first study to demonstrate that group self-identification (a) is a generalizable construct across different types of adolescent samples, (b) is related to use of drugs other than tobacco, and (c) remains a significant correlate of drug use controlling for its relations with demographic variables and several other psychosocial variables. 相似文献

This article considers the meaning and significance of authority, and its relevance to the transference process, within the framework of psychotherapy in the orthodox Jewish (Haredi) community in Israel. In this community, deeply-rooted habits of obedience to the commandments of the Torah and the authority of the Rabbi are integral to maintaining an orthodox way of life. Clinical vignettes with Haredi patients are presented to illustrate the complexities that arise when both patient and therapist belong to the orthodox community, and highlight the authority-related issues that are central to the therapy. This combination of factors requires a sensitive and finely-tuned approach which will enable the therapist to maintain the treatment framework while still accommodating the orthodox way of life. 相似文献

What psychological response does war and forced displacement evoke in victims? How do survivors of war communicate their experiences to their children? Finally, what culture does the psychological response to loss shape? Using data collected through interviews, psychological consultations, and children’s drawings from two sources—the ongoing Syrian civil war and the Bosnian war of 1992–1995, this paper suggests that the experience of the war generation becomes the organizing axis of their identity and that of their children. It seeks to demonstrate that survivor parents communicate their experience of loss through gesture, act, and object rather than through a coherent narrative. Whereas survivor children use metaphoric and metonymic readings of their parents’ everyday performance in order to construct meaning and form their identities as descendants of a given family. This paper argues that such an identity is characterized by ambivalence towards the self and towards others, melancholic longing for an idealized pre-war past, and the impossibility of letting it go. 相似文献

The present paper starts from the reflection that there is a curious “phenomenological gap” in psychoanalysis when it comes to processes of splitting and to describing the “life” of psychic fragments resulting from processes of splitting. In simpler terms, we are often in a position to lack a precise understanding of what is being split and how the splitting occurs. I argue that although Melanie Klein’s work is often engaged when talking of splitting (particularly through discussions on identification, projection and projective identification), there are some important phenomenological opacities in her construction. I show that by orchestrating a dialogue between Melanie Klein and Sándor Ferenczi, we arrive at a fuller and more substantive conception of psychic splitting and of the psychic life of fragments which are the result of splitting. This is even more meaningful because there are some unacknowledged genealogical connections between Ferenczian concepts and Kleinian concepts, which I here explore. While with Klein we remain in the domain of “good” and “bad” objects—polarised objects which are constantly split and projected—with Ferenczi we are able to also give an account of complicated forms of imitation producing psychic fragments and with a “dark” side of identification, which he calls “identification with the aggressor”. While attempting to take steps toward imagining a dialogue between Klein and Ferenczi, I note a certain silent “Ferenczian turn” in a late text by Melanie Klein, “On the Development of Mental Functioning”, written in 1958. In particular, I reflect on her reference to some “terrifying figures” of the psyche, which cannot be accounted for simply as the persecutory parts of the super-ego but are instead more adequately read as more enigmatic and more primitive psychic fragments, resulting from processes of splitting. 相似文献
