The Harvard Pigeon Lab under Herrnstein

The history of the Harvard Pigeon Lab is a history of two periods of remarkable productivity, the first under Skinner's leadership and the second under Herrnstein's. In each period, graduate students flocked to the leader and then began stimulating one another. Chance favored Herrnstein's leadership, too, because an unusually large number of graduate students were admitted in the fall of 1962. In each period, productivity declined as the leader lost interest in the laboratory and withdrew. Directly and indirectly, the laboratory finally died as a result of the cognitive "revolution." Skinner and his students saw the possibility of a natural science of behavior and set about establishing that science based on concepts such as response rate, stimulus control, and schedules of reinforcement. Herrnstein and his students saw that the science could be quantitative and set about making it so, with relative response rate, the matching law, and the psychophysics of choice (analogous to S. S. Stevens' psychophysics). The history might provide a golden research opportunity for someone interested in the impact of such self-organizing research groups on the progress of science.     

The watershed years of 1958-1962 in the Harvard Pigeon Lab

During the years 1958-1962, the final years of support by the National Science Foundation for B. F. Skinner's Pigeon Lab in Memorial Hall at Harvard University, 20 or so pigeon experiments (plus some with other organisms) ran concurrently 7 days a week. The research style emphasized experimental analyses, exploratory procedures, and the parametric exploration of variables. This reminiscence describes some features of the laboratory, the context within which it operated, and the activities of some of those who participated in it.     

The living legacy of the Harvard Pigeon Lab: quantitative analysis in the wide world

From the Harvard Pigeon Lab of the 1960s arose a behavior-analytic approach that was quantitative and rigorous, rooted in Herrnstein's matching law. Researchers modified the matching law to describe choice behavior in a variety of different settings and examined its relations with other quantitative models. Beginning in the early 1970s, researchers began using the Harvard Pigeon Lab's quantitative framework to study in the laboratory specific aspects of the world outside the laboratory. Much of this work concerned investigations of self-control-choice of a larger, more delayed reinforcer over a smaller, less delayed reinforcer. Experiments using a quantitative framework derived from the matching law have also been conducted outside the laboratory; however, these have been far less frequent. Current and future researchers will benefit the field by devising new, creative ways to investigate the matching law and related quantitative models outside the laboratory. Such research can help to demonstrate the validity of these models as basic principles of behavior, can enhance public opinion of and rewards for such research, and can stimulate further development of the Harvard Pigeon Lab's quantitative approach by using that approach with new variables.     

Melioration behaviour in the Harvard game is reduced by simplifying decision outcomes

Self-control experiments have previously been highlighted as examples of suboptimal decision making. In one such experiment, the Harvard game, participants make repeated choices between two alternatives. One alternative has a higher immediate pay-off than the other, but with repeated choices results in a lower overall pay-off. Preference for the alternative with the higher immediate pay-off seems to be impulsive and will result in a failure to maximize pay-offs. We report an experiment that modifies the Harvard game, dividing the pay-off from each choice into two separate consequences—the immediate and the historic components. Choosing the alternative with the higher immediate pay-off ends the session prematurely, leading to a loss of opportunities to earn further pay-offs and ultimately to a reduced overall pay-off. This makes it easier for participants to learn the outcomes of their actions. It also provides the opportunity for a further test of normative decision making by means of one of its most specific and paradoxical predictions—that the truly rational agent should switch from self-control to impulsivity toward the end of the experimental sessions. The finding that participants maximize their expected utility by both overcoming impulsivity and learning to switch implies that melioration behaviour is not due to the lure of impulsivity, but due to the difficulty of learning which components are included in the pay-off schedules.

Responsible Conduct of Research Training and Trust Between Research Postgraduate Students and Supervisors

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.     

'A serious venture': John Rodker (1894-1955) and the Imago Publishing Company (1939-60)

John Rodker (1894-1955) was the founder of the British publishing house--the Imago Publishing Company--which undertook the republication of the complete works of Sigmund Freud in German just before World War II. Rodker, himself a writer as well as a publisher, was initially tempted by a psychoanalytic career; numerous obstacles, however, lay in his path. War, along with the complicated management of the royalties from Freud's writings, compromised the progress of what seemed to him to be 'a serious venture'. Besides Rodker, we meet numerous actors of the psychoanalytic movement: Anna Freud, Marie Bonaparte, Ernest Jones, James Strachey, all of whom had worked for the dissemination of Freud's writings. This paper shows how the English language gradually became the 'official norm' for psychoanalysts. According to the editors of the Standard Edition, at that time 'nothing new [was] being written' in German or in French. The failure of the Gesammelte Werke project signalled the end of an era in which psychoanalysis was mainly written about in German.     

Washington rises: public financial support for intellectual disability in the United States, 1955-2004

Public financial support for intellectual disability in the United States grew from 2.3 billion in 1955 to 82.6 billion in 2004, and the federal government emerged during this period as the principal provider of such support. Notwithstanding this unprecedented growth in financial support, many inequities persist today in the distribution of financial resources and services across states, communities, families and to individual disabled consumers. Moreover, tens of thousands of persons with intellectual disabilities continue to live in institutions and nursing homes, waiting lists and aging caregivers are growing rapidly, and family support and supported employment programs receive limited funding. Research and training support has declined significantly in comparison to the growing financial commitments for services and income maintenance. To address these and other issues, the author suggests commissioning a new "President's Panel on Intellectual Disability" modeled on President Kennedy's landmark 1961 Panel on Mental Retardation. The new panel would be appointed during the first months of the new presidential administration in 2009 and deliver its report to the President in 2011, commemorating the 50(th) anniversary of the original President's Panel.

Dimensions of Perfectionism Mediate the Relationship Between Parenting Styles and Coping

This study explored the relationships among parenting styles, perfectionism dimensions, and coping through an online survey. With structural equation modeling and a bootstrap method, the results demonstrated that perfectionism dimensions mediated the relationship between parenting styles and coping strategies among 376 undergraduates (women, 80.6%; men, 19.4%; Caucasian, 94.4%). Thus, parenting practices may be antecedents to perfectionism dimensions that contribute to an individual's ability to cope with stressful situations. The implications for counselors and practice are discussed.
