The mental health histories of the 448 children 15 and 16 years of age who were admitted to state-operated children's psychiatric inpatient services in New York during 1982 were reviewed for the 11 year period through April 1993, Thirty-three percent were served as adults (after age 18) in the state-operated adult civil mental health system; 42% of these individuals were still receiving services at the end of the period. 113 of the 146 individuals served as adults were served only in the civil system. Thirteen percent of the cohort received some of their mental health services as adults in the state-operated adult forensic mental health system due to criminal law involvement. This includes nine percent who received mental health services while they were inmates in state prisons. Twenty four of the 57 forensic clients received services as adults only in the forensic system. Diagnostic, demographic, and service history characteristics of the groups were compared to foster an early understanding of policy and programmatic issues related to movement from the child mental health system to the adult system. Baseline (1982) information was used to identify predictors of later service utilization. 相似文献

College undergraduates were given repeated opportunities to choose between a fixed-ratio and a progressive-ratio schedule of reinforcement. Completions of a progressive-ratio schedule produced points (exchangeable for money) and incremented that response requirement by 20 responses with each consecutive choice. In the reset condition, completion of a fixed ratio produced the same number of points and also reset the progressive ratio back to its initial value. In the no-reset condition, the progressive ratio continued to increase by increments of 20 throughout the session with each successive selection of this schedule, irrespective of fixed-ratio choices. Subjects' schedule choices were sensitive to parametric manipulations of the size of the fixed-ratio schedule and were consistent with predictions made on the basis of minimizing the number of responses emitted per point earned, which is a principle of most optimality theories. Also, the present results suggest that if data from human performances are to be compared with results for other species, humans should be exposed to schedules of reinforcement for long periods of time, as is commonly done with nonhuman subjects. 相似文献

In-depth interviews were performed with 12 adolescents (Swedish students, 16-19 years). Three questions were probed; what do adolescents say on the subjects of (a) themselves, (b) their existential questions, and (c) their adult contacts. The first two questions were aimed at elucidating the process of identity development, the last one at factors that may be influencing this process. The results showed that (a) balancing and controlling one's own needs and wishes in relation to others' was a central issue, (b) existential questions mainly concerned the personal future, (c) adult contacts outside the family were scarce and (d) all respondents expressed a need for adult contacts as sources of knowledge and experience. The conclusions are that identity formation during late adolescence consists of integrative issues where adults play a specific and important role. 相似文献

Equivalence relations between visual stimuli: the functional role of naming 总被引:2,自引:2,他引:0 下载免费PDF全文
The functionality of verbal behavior in equivalence class formation was demonstrated by training 30 verbally able adults using different combinations of the same easily nameable, yet formally unrelated, pictorial stimuli. Match-to-sample baselines for four four-member classes were established sequentially (i.e., AB-BC-CD), with participants in the rhyme condition trained to select comparisons whose normative names rhymed with those of the samples. For the orthogonal condition, class rearrangement was such that on every trial all available comparisons' names rhymed with each other, but not with the name of the sample. In the diagonal condition, stimuli were allocated pseudorandomly as samples and comparisons. Although all participants maintained baseline discriminations prior to emergent testing, equivalence was confined almost exclusively to the rhyme condition, in which it was ubiquitous. These participants also required less training than those in the control conditions, among whom effects of nodal distance were observed most strongly. Subsequent testing presented participants with no-reinforcement trials involving novel pictorial stimuli, in which one of the available comparisons' names always rhymed with that of the sample. All rhyme participants consistently selected these comparisons. Results indicate that visual stimuli are named, that the phonological properties of those names can influence equivalence class formation, and that the emergence of untrained discriminations may, under certain circumstances, be rule governed. 相似文献

Understanding the human spirit, the thinking, motivating, feeling aspect of a person, need not entail supernatural reference in any more than a boundary sense. Methodological naturalism accounts for many putatively supernatural experiences in terms of naturalistic and scientific research. Fairy tales have natural functions, naturalistic accounts of miracles can have moral and spiritual power, and neuropsychological research can have value in understanding experiences of ghosts, apparitions, and presences. Even beliefs in personal immortality, at odds with current neurobiology, may serve a range of psychological functions and may raise more moral questions than they answer. Naturalistic accounts can make spiritual explorations possible where supernatural answers provide epistemic barriers. 相似文献

Biological self reference idioms in brain-centered or nervous-system-centered self determination of the consious Self reveal
an interesting contrast with biological self-determination by immunological self/non-self discrimination. This contrast is
both biological and epistemological. In contrast to the consciousness conscious of itself, the immunological self-determination
imposes a protective mechanism against self-recognition (Coutinho et al. 1984), which adds to a largely unconscious achievement
of the biological Self (Popper 1977; Medawar 1959). The latter viewpoint is in contrast with the immunological Self-determination
as an essentially cognitive process as expressed in the analysis of Tauber (1994). Comparison of the immune system in vertebrates
and invertebrates, according to new biological insights, has contributed to a better understanding of the relative role of
innate (or inherited) immunity versus immunity acquired during each individual life. Also in this respect, immunological self-achievement
shows both a striking analogy and a fundamental discrepancy with the activity of the nervous system.
The analysis of immunological Self/non-self discrimination versus brain-centered self-determination adds to the understanding
of the function paradigm in biological self-reference idioms, especially when regarding the importance of the connectivity
notion in both systems. Adopting functional explanatory schemes for understanding immunological self-non-self discrimination,
as well as for the understanding of functional mapping of the brain at (conscious) activity (Friston et al. 1993; Frith et
al. 1995), forwards the notion of effective/functional connectivity. Network connectivity not only is a primary question in
solving the dimensionality question for immunological ‘idiotypic networks’ (Jerne 1974a, b; 1984), it may also have an important
value in describing phase transitions in the development of both immune and nervous systems.

We describe a study in which young and older groups of Bangladeshi participants recalled and dated autobiographical memories from across the lifespan. Memories were subsequently plotted in terms of the age of participants at time of encoding. As expected the reminiscence bump, preferential recall of memories from the period of 10 to 30 years of age, was observed. This was very marked in the younger group and but less so in the older group who also showed a second bump in the period 35 to 55 years of age. This second bump corresponded to the period of national conflict between Pakistan and the Bengalee people that resulted in the formation of an independent Bangladesh. It is proposed that both the reminiscence bump and later periods of unexpected rises in recall can be accounted for by the raised accessibility of sets of memories and this in turn is a product of the privileged encoding of highly self-relevant experiences. 相似文献

This article explores theories of selfhood by juxtaposing them against an individual's lived experience. As Ronald Manheimer reflects upon his friendship with Hildegard, a student from one of the classes that he taught at a senior center in Olympia, Washington, he compares this experience with that described by various theories of selfhood. Building on the linguistic self, the narrative self, and the relational self, Manheimer posits a self that exists through time within a network of relationships, not a fixed determined self, but a dynamic self, subject to revision and reimagining. 相似文献

The concept of guardianship, its associated principles, distinctions, and articulation of the legal needs of the elderly are introduced via a review of well-canvassed criticisms of Canadian guardianship legislation. Claims that the reformed legislation of Alberta, Quebec, and British Columbia represent models of adequate adult guardianship compared with traditional (archaic lunacy) law are examined. This paper argues that these renovated models exhibit a dubious normative advance over traditional legislation. Specifically, the normative presuppositions of the reformed legislation, such as, restriction to an autonomy-paternalism framework, and the norms of the liberal individual and state, obscure important issues in at least two key areas which challenge the models' assumptions; namely, assessment and legal competence and assessment and need. The development of guardianship laws and of social arrangements that are more responsive to the life experiences of the elderly requires critical re-articulation of the nature of individuals and their communities. 相似文献
