STATED WILLINGNESS TO PAY FOR PUBLIC GOODS:

Abstract— In the contingent valuation method for the valuation of public goods, survey respondents are asked to indicate the amount they are willing to pay (WTP) for the provision of a good. We contrast economic and psychological analyses of WTP and describe a study in which respondents indicated their WTP to prevent or to remedy threats to public health or to the environment, attributed either to human or to natural causes. WTP was significantly higher when the cause of a harm was human, though the effect was not large. The means of WTP for 16 issues were highly correlated with the means of other measures of attitude, including a simple rating of the importance of the threat. The responses are better described as expressions of attitudes than as indications of economic value, contrary to the assumptions of the contingent valuation method.     

Depression in patients with spinal cord injuries: A synthesis of cognitive and somatic processes

Depression in some patients with spinal cord injuries may be clinically significant and, when present, should be treated to decrease morbidity including decreased physical functioning. Depression associated with spinal cord injury (SCI) may be misevaluated, due to (1) nonspecific multifactorial production of depression symptoms and (2) SCI-specific decrease in somatic sensory central nervous system input. The Somatic Suppression Hypothesis suggests that SCI patients have difficulty experiencing any intense emotion because of suppression of physiological arousal. In addition, cognitive processes that may reduce depression in SCI patients include: (1) attribution of somatic symptoms of depression to medical (biological) causes, (2) realistic, positive expectations for physical improvement, and (3) the perception that the disability of the SCI is only minimally related to the patient’s self-care after complete evaluation. Health personnel should accept lack of depression in SCI, and should encourage positive realistic expectations of recovery.     

Effects of Race,Racial Identity Development,and Orientation Style on Perceived Consultant Effectiveness

This study explores Black teachers' preferences for and ratings of consultant effectiveness as a function of consultant race, consultant style, and teacher stage of racial identity development. No significant differences were noted in preferences for either a same- or opposite-race consultant. Participants preferred and rated as more effective an instrumentally oriented consultant.     

Family coping strategies and the rural Appalachian working poor

Naturalistic research methods were used in this study to collect the voices, ideas, and opinions of rural, working poor, Appalachian families from Southeast Ohio about the stress of poverty in family life and family coping in the face of poverty. This data should be of interest to the professional family therapist who practices with the working poor.     

Live supervision in the postmodern era of family therapy: Issues,reflections, and questions

This article asserts that the family therapy field is approaching an epistemological shift from structuralism and positivism to postmodernism and relativism. The confluence of these movements: feminism, constructivism/constructionism, and cultural relativism is cited as a major impetus for the shift. Live supervision is examined within the context of this transformation, with a discussion of implications for the future.     

Supervising the person of the therapist: Issues,challenges and dilemmas

A major critical issue in marriage and family therapy today is the professionalization of the discipline. Thus the focus on training individuals for a career in marriage and family therapy necessitates the revisitation of the debate over personal growth versus skill development. The trend toward training the person of the therapist, however, would suggest that the field is moving toward the integration of self awareness and skill in the therapeutic system. With the popularization of training the person of the therapist comes other issues, challenges, and dilemmas for the field, including the crucial issue of training gender and culturally sensitive therapists. The potential for creating dual relationships when training the person of the therapist is both a dilemma and a challenge.     

Time-stamping computer events to report .1-msec accuracy of events in the Micro Experimental Laboratory

A critical problem in most real-time programming tasks is the verification that timing of the presented displays and recorded events occur at the expected times. It is often difficult for psychologists to verify critical timing because of the lack of costly specialized tools and technicians to measure events with millisecond accuracy. Algorithms utilized in a new Time Audit mechanism, added to the Micro Experimental Laboratory, are described. This new mechanism involves the recording and time stamping of all input and output events with 0.1-msec accuracy. This allows the experimenter to determine the initiation, duration, and termination of each event and also makes it possible to relate these events to the synchronization of the screen refresh cycle. A customized user interface provides a time log and event-tracing feature that enables nonprogrammers to determine the duration of command execution to the .1-msec level, allowing rapid, precise assessment of program execution. The resulting time log provides a detailed specification of the experimental events for debugging and a permanent record of the experimental procedure.     

Classical Psychophysics and the Assessment of Agreement and Accuracy In Judgments of Personality

ABSTRACT The just noticeable difference (jnd) unit of classical psycho-physics is introduced as a new way to describe accuracy and agreement in observer evaluations of personality. A formula for estimating jnd's from typically available summary statistics is derived from Thurstone's law of comparative judgment. A study examining four traits judged in 10 samples of subjects where the design permitted the calculation of jnd's by the method of paired comparisons indicated that the formula predicted the empirically derived jnd's associated with the mean judge ratings with considerable precision. Jnd's of criterion measures were also predicted, and while fit was somewhat less impressive in this case, there was still appreciable convergence between predicted and empirical values. The implications of jnd measures of agreement and accuracy are discussed. These implications include (a) possibilities for increased understanding of bias in observer judgments, (b) a new recognition that equal correlations to external criteria do not necessarily imply equal accuracy, and (c) alternative ways of describing the magnitude of effect in psychological research.     

Relevant consequence and empirical inquiry

A criterion of adequacy is proposed for theories of relevant consequence. According to the criterion, scientists whose deductive reasoning is limited to some proposed subset of the standard consequence relation must not thereby suffer a reduction in scientific competence. A simple theory of relevant consequence is introduced and shown to satisfy the criterion with respect to a formally defined paradigm of empirical inquiry.Research support was provided by the Office of Naval Research under contract No. N00014-89-J-1725 to Osherson and Weinstein, Swiss National Science Foundation under contract No. 21-32399.91 and by a Siemens Corporation grant to Osherson.
