Successive, simultaneous, and anticipatory contrast in the consumption of saccharin solutions

Contrast effects were obtained in rats in the consumption of saccharin solutions in three different paradigms. Degree of negative contrast varied as a function of concentration disparity, but not equally in the three procedures. Successive negative contrast occurred following shifts from 0.15% to either 0.075% or 0.05% saccharin but did not occur following shifts to 0.10% or 0.125% saccharin. Some degree of simultaneous contrast was obtained with all four concentration disparities. Anticipatory contrast, where the intake of the first substance is suppressed by a more preferred second substance, occurred only in the case of the 0.05%-0.15% difference in concentrations. It was suggested that the several contrast paradigms engage somewhat different psychological processes differentially involving emotional, sensory, and associative mechanisms, but all lead to behavior based on relative value. A modification of Toates's (1981) incentive model of ingestive behavior was suggested to incorporate relativity effects based on both associative and nonassociative factors in the consumption of both nutritive and nonnutritive substances.     

Moving the debate forward in small steps: A reply to Morrison

Morrison (1996) criticised the authors' 1995 evaluation on three main grounds: that it was too narrow, that it was circular, and that the model evaluated was contradictory. It is argued that the narrow focus was deliberate, that the methodology was standard and logical, and that the framework evaluated was coherent. Although the authors agree with Morrison in some respects, e.g. on the value of variety of methodology, there seems to be a basic difference in view on scientific method. The authors see research as (mainly) small steps which are erratic but generally cumulative; Morrison appears to favour grand-scale, multi-purpose research.     

Ethics education in science and engineering: The case of animal research

Conclusion The past one hundred fifty years of debate over the use of animals in research and testing has been characterized mainly byad hominem attacks and on uncritical rejection of the other sides’ arguments. In the classroom, it is important to avoid repeating exercises in public relations and to demand sound scholarship. This paper is a modification of material originally included in the handbook which accompanied the American Association for the Advancement of Science (AAAS) Seminar “Teaching Ethics in Science and Engineering”, 10–11 February 1993.     

Hegel and self‐actualization

Abstract

Hegel says that mind develops through three phases, which he calls soul, consciousness, and mind. By referring to these three phases as the Primary level, the Social level and the Realizing level, it makes it clearer that they link up with thoroughly familiar phenomena in the field of psychotherapy and with contemporary life generally. In fact, they give a new angle on the whole process of self‐actualization, which throws light on many topics in humanistic psychology.     

EPIPHANY PHILOSOPHERS: AFTERWORD

Being a theist makes a difference, but not so much to what propositions we assent to, nor to an expanded ontology of spiritual entities. Rather, it is concerned with what commitments we enter into, and involves a participatory engagement with a broader reality then we might have supposed was possible. Embodied practices are a crucial part of the contemplative path, which draws on the wisdom of the body. This leads on to a “labor of culture.” Our present culture is not obviously as secular as supposed to be, but what has now become sacred is a strong sense of the individual ego, around which many ethical and political commitments are built, and which sits uneasily with our widely accepted mechanistic view of life. The crucial challenge to artificial intelligence is whether it can find ways of enhancing the mutual recognition that is crucial to the ethical life.     

Assessing the quality of child investigative interviewing in the Netherlands

Using evidence‐based guidelines to interview children is an important means to obtain complete and accurate accounts. In the current study, we examined the quality of child investigative interviewing in the Netherlands. To examine this, we compared the Dutch Scenario Model with the National Institute of Child Health and Human Development Protocol and interviews from countries that did not follow a specific protocol. Our principal result was that Dutch child interviewers rarely asked recommended open prompts that are known to elicit detailed and accurate testimonies from children. Furthermore, we found that the scenario model contained the highest number of directive questions compared with interviews from other countries. Our findings show that the Dutch Scenario Model is not well aligned with current research‐based recommendations for interviewing children.     

Closing the gap? Some questions for neurophenomenology

In his 1996 paper “Neurophenomenology: A methodological remedy for the hard problem,” Francisco Varela called for a union of Husserlian phenomenology and cognitive science. Varela's call hasn't gone unanswered, and recent years have seen the development of a small but growing literature intent on exploring the interface between phenomenology and cognitive science. But despite these developments, there is still some obscurity about what exactly neurophenomenology is. What are neurophenomenologists trying to do, and how are they trying to do it? To what extent is neurophenomenology a distinctive and unified research programme? In this paper I attempt to shed some light on these questions.
