Concurrent access to two concentrations of orally delivered phencyclidine: effects of feeding conditions.

Two experiments addressed the effects of food satiation and deprivation on oral self-administration of two concurrently available phencyclidine concentrations. In the first experiment, 8 rhesus monkeys self-administered either of two concentrations of phencyclidine ("PCP, angel dust") and water under concurrent fixed-ratio 16 schedules. One concentration was always held constant (0.25 mg/mL) while a series of other phencyclidine concentrations, ranging from 0 (water) to 1.0 mg/mL, was presented in a nonsystematic order. Initially the monkeys were tested while food satiated, and the procedure was then repeated during food deprivation. The monkeys usually selected the higher concentration within the first few minutes of the session, indicating that taste and/or other immediate postingestional effects were important factors. Contrary to a number of previous reports, there were no consistent differences across subjects in the mean number of liquid deliveries or mean drug intake (mg/kg) during food satiation and deprivation. However, for all monkeys the within-session time course of responding during food satiation consistently differed from that during deprivation. A second experiment assessed whether the failure to find consistent differences in drug intake during food satiation and deprivation had been due to the history of concurrent access to different phencyclidine concentrations or to the extended experience with phencyclidine under food-satiation conditions. Six additional monkeys (Group 2) were exposed to the phencyclidine self-administration procedure (during food satiation and deprivation) for the same length of time as the monkeys in Experiment 1 (Group 1), except they received only concurrent access to phencyclidine (0.25 mg/mL) and water. Both groups then received concurrent access to phencyclidine and water during five repeated cycles of food deprivation and satiation. There were also marked individual differences in Group 2: During food satiation, 2 of the monkeys' responding increased, 1 showed no change, and 3 decreased. Examination of a number of historical variables indicated that the greater the percentage of total sessions spent during food satiation with phencyclidine available (before these experiments began), the greater the amounts of phencyclidine consumed during food satiation and the smaller the differences in phencyclidine intake when the two feeding conditions were compared.     

Drug-behavior interaction history: modification of the effects of morphine on punished behavior.

Squirrel monkeys were trained to respond under a multiple fixed-interval, fixed-interval schedule in which the first response after 5 min terminated a visual stimulus in the presence of which electric shocks could occur. During one component of the schedule, correlated with one color of stimulus lights, every 30th response also produced electric shock; responding was suppressed during this component to approximately 10 to 12% of that occurring in the alternate component in which responding was not punished. In contrast to previous research, morphine (0.03 to 1.0 mg/kg) increased punished responding. Unpunished responding, however, was either not affected or decreased at doses of morphine that increased punished responding. Increases in rate of punished responding also occurred when the single-schedule punishment condition was studied alone in these animals. Subsequent experimentation, which systematically analyzed the development of the rate-enhancing effects of morphine on punished responding, involved the study of drug effects in additional monkeys trained initially under a single-schedule punishment condition. The effects of morphine on punished responding were studied before, after, and then during exposure to the multiple schedule that included a component in which responding was not punished. Increases in response rate with morphine did not occur until it was administered during exposure to the multiple schedule that included a component in which responding was not punished. As with the other monkeys, once the rate increases in punished responding occurred under the multiple schedule, these effects of morphine persisted, even when the multiple schedule was removed.(ABSTRACT TRUNCATED AT 250 WORDS)     

Social Activism's Possibility through Perspectives of Gloria Anzaldúa,Walter Benjamin and C. G. Jung1

This paper explores the vertices of Jung's, Anzaldúa's and Benjamin's distinct ontologies and the way in which they connect in the shared recognition that what has been estranged in human history is enigmatically lodged in the world's fabric today. Cultural distress, in other words, is the outcome of what has become repudiated in the self and the collective across time. From this perspective, the paper argues that we have a collective responsibility to listen to the claims of the dead laid bare in moments of contemporary real-world danger and it elaborates the psychical dimensions of being that are cultivated in times of danger. The author contends that these psychical presences are the dead of human history including our ancestral heritage that linger and possibly may penetrate our awareness. They haunt and hold a potential to animate our movement towards a sublimatory process that can be seen as a precursor to social responsiveness and action. The author explores this through her own experience with an example of the spawning of spiritual activism within the socio-political maelstrom of AIDS.     

Philosophy as a thief?

This is a performative piece of writing in the presence of and inspired by Richard Shusterman's Philosophy and the Art of Writing. It tries to show that the relationship between the act of writing and the formation of our human consciousness (philosophical and, more deeply, poietic) is a developing and growing process through history, and before it. The dominance of an image consciousness was slowly challenged and then replaced by a linguistic consciousness with the advent of writing, and accelerated by the invention of printing and mass literacy. Shusterman teaches us an embodied kind of philosophizing that uses the word but isn't limited by it. This paper suggests that a return to image consciousness has already occurred and that the old book consciousness is disappearing. Lessons from the book consciousness are offered.     

Empirical tests of scientific realism: A quantitative framework

The scientific realism debate in philosophy of science raises some intriguing methodological issues. Scientific realism posits a link between a scientific theory's observational and referential success. This opens the possibility of testing the thesis empirically, by searching for evidence of such a link in the record of theories put forward in the history of science. Many realist philosophers working today propose case study methodology as a way of carrying out such a test. This article argues that a qualitative method such as case study methodology is not adequate for this purpose, for two reasons: to test scientific realism is to pose an effects-of-causes question, and observational and referential success are quantities that theories possess to a greater or lesser degree. The article concludes that an empirical test of scientific realism requires a quantitative method.     

Dance becomes therapeutic in the mid to late 20th century

The convergence of dance art and therapeutic culture engendered the development of dance-movement therapy in the mid to late 20th century internationally. This article traces the sociopolitical, institutional, and aesthetic influences that coalesced in this process by contrasting histories of dance-movement therapy in Hungary and in the United States. The professionalization dance-movement therapy, through which it established its own theory, practice, and training institutions, occurred first in the United States in the late 1940s. Modern dancers in the United States began to conceptualize their activity as therapeutic, and the dancer as a (secular) healer, a therapist. The influx of therapeutic concepts into the field of dance is viewed as an example of therapeutic discourse permeating various areas of life in the 20th century. The Hungarian case provides a contrasting history of therapeutic culture, one that deviates from the predominant view of the phenomenon as a product of the global spread of Western modernization and the growth of free-market capitalism. Hungarian movement and dance therapy indeed developed independently from its American predecessor. Its history is intimately tied to the sociopolitical context of state-socialist period, particularly to the institutionalization of psychotherapy in public hospitals, and to the adaptation of Western group psychotherapies within the informal setting of the “second public sphere.” The legacy of Michael Balint and the British object-relations school provided its theoretical framework. Its methodology was rooted in postmodern dance. The methodological differences between American dance-movement therapy and the Hungarian method reflects the shift in dance aesthetics that occurred internationally between 1940 and 1980s.     

Psychology and the fall of Communism: The special case of (East) Germany

The fall of Communism is now universally agreed to be what the philosopher Hegel called a world historical event—one that few predicted but nearly everyone saw as inevitable after it happened. In the aftermath many lives—and worldviews—changed, not only, but also in the human sciences. These remarks attempt to address in a preliminary way both the impact of the fall of Communism on psychology in former East Germany (including changes in personnel and approach) and the ways in which these sciences were employed as resources for reflection on the Communist past as well as the transition to new social and political regimes.     

Australia Day or Invasion Day? Perspectives on the Continuing Impact of Colonialism Underlies Public Contestations Around Australia's National Day

The ways in which collective memories are constructed in the present is important in explaining how people choose to commemorate their nation's history. The present research focused on the context of Australia Day, a controversial national holiday that falls on January 26, which is a date that marks the beginning of colonization. We conducted field surveys of community members participating in an Invasion Day protest pushing for Indigenous rights (n = 219) and community members enjoying the public holiday in a public park (n = 174). We found that greater recognition of colonial history explained protesters' (vs. nonprotesters') greater support for changing the date of Australia Day. Further, protesters' lower levels of perceived continuity and higher levels of desired continuity of First Australian culture was linked to greater support for changing the date of Australia Day compared to the nonprotesters. These findings suggest that creating consensus over contested collective memories of a nation's history requires greater recognition of the ongoing impact of past atrocities.
