An Adamsian Theory of Intrinsic Value

In this paper I develop a theological account of intrinsic value drawn from some passages in Robert Merrihew Adams’ book Finite and Infinite Goods. First I explain why Adams’ work on this topic is interesting, situate his theory within the broader literature on intrinsic value, and draw attention to some of its revisionist features. Next I state the theory, raise some problems for it, and refine it in light of those problems. Then I illustrate how the refined theory works by showing that it has the resources to deal with some seemingly formidable objections.     

A comparison of laboratory and clinical working memory tests and their prediction of fluid intelligence

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures (operation span, listening span, and n-back), as well as the WM subtests from the Wechsler Adult Intelligence Scale-III and the Wechsler Memory Scale-III. Performance on all of the WM subtests of the clinical batteries shared positive correlations with the lab measures; however, the Arithmetic and Spatial Span subtests shared lower correlations than the other WM tests. Factor analyses revealed that a factor comprising scores from the three lab WM measures and the clinical subtest, Letter-Number Sequencing (LNS), provided the best measurement of WM. Additionally, a latent variable approach was taken using fluid intelligence as a criterion construct to further discriminate between the WM tests. The results revealed that the lab measures, along with the LNS task, were the best predictors of fluid abilities.     

Diagnosis and Assessment of Depression and Suicidality Using the NIMH Diagnostic Interview Schedule for Children (DISC-2.3)

The Diagnostic Interview Schedule for Children (DISC-2.3) was studied in a sample of 265 adolescent inpatients to determine type and concurrent validity of depressive symptoms and depressive disorder diagnoses for different DISC-2.3 informants (parent, adolescent, both). The Children's Depression Rating Scale — Revised, Reynolds Adolescent Depression Scale (RADS), Suicide Ideation Questionnaire — Junior, Spectrum of Suicide Behavior Scale, and clinical consensus diagnoses were used to assess concurrent validity. Results indicated that (1) parents, compared to adolescents, reported a higher prevalence of all depressive symptoms with the exception of weight change; (2) DISC-2.3 depressive and suicidality symptoms were related positively to independent validating criteria for all informant conditions, suggesting good concurrent validity; (3) the DISC-2.3 both informant condition correctly identified the most depressive disorders; and (4) the parent, but not the adolescent, DISC-2.3 Informant condition contributed to the prediction of clinical consensus diagnoses of depression after taking into account RADS scores.     

Conditioned suppression/avoidance as a procedure for testing hearing in birds: The domestic pigeon (Columba livia)

Although the domestic pigeon is commonly used in learning experiments, it is a notoriously difficult subject in auditory psychophysical experiments, even those in which it need only respond when it detects a sound. This is because pigeons tend to respond in the absence of sound—that is, they have a high false-positive rate—which makes it difficult to determine a pigeon’s audiogram. However, false positives are easily controlled in the method of conditioned suppression/avoidance, in which a pigeon is trained to peck a key to obtain food and to stop pecking whenever it detects a sound that signals impending electric shock. Here, we describe how to determine psychophysical thresholds in pigeons using a method of conditioned suppression in which avoidable shock is delivered through a bead chain wrapped around the base of a pigeon’s wings. The resulting audiogram spans the range from 2 to 8000 Hz; it falls approximately in the middle of the distribution of previous pigeon audiograms and supports the finding of Kreithen and Quine (Journal of Comparative Physiology 129:1–4, 1979) that pigeons hear infrasound.     

Probabilism Today: Permissibility and Multi-Account Ethics

In ethics, ‘probabilism’ refers to a position defended by a number of Catholic theologians, mainly in the sixteenth and seventeenth centuries. They held that, when one is uncertain which of a range of actions is the right one to perform, it is permissible to perform any which has a good chance of being the right one—even if there is another which has a better chance. This paper considers the value of this position from the viewpoint of modern ethical philosophy. The unusual nature of probabilism as a theory focusing upon permissibility, rather than right-making properties, is explored and related to some modern attempts to set out ‘satisficing’ and ‘hybrid’ ethical theories. Such theories try to distinguish between what is best and what is permissible, and probabilism can be understood as an alternative way of supplementing a theory of right-making properties by adding to it a theory of permissibility. But a more radical version is also possible, where one abandons any attempt to identify right actions or right-making properties, and instead considers permissibility alone. Accordingly, a ‘multi-account theory’ of permissibility is proposed and defended as a model of how many people actually make moral decisions.

Environmental Influences on Ethical Decision Making: Climate and Environmental Predictors of Research Integrity

It is commonly held that early career experiences influence ethical behavior. One way early career experiences might operate is to influence the decisions people make when presented with problems that raise ethical concerns. To test this proposition, 102 first-year doctoral students were asked to complete a series of measures examining ethical decision making along with a series of measures examining environmental experiences and climate perceptions. Factoring of the environmental measure yielded five dimensions: professional leadership, poor coping, lack of rewards, limited competitive pressure, and poor career direction. Factoring of the climate inventory yielded four dimensions: equity, interpersonal conflict, occupational engagement, and work commitment. When these dimensions were used to predict performance on the ethical decision-making task, it was found that the environmental dimensions were better predictors than the climate dimensions. The implications of these findings for research on ethical conduct are discussed.     

A Sensemaking Approach to Ethics Training for Scientists: Preliminary Evidence of Training Effectiveness

In recent years, we have seen a new concern with ethics training for research and development professionals. Although ethics training has become more common, the effectiveness of the training being provided is open to question. In the present effort, a new ethics training course was developed that stresses the importance of the strategies people apply to make sense of ethical problems. The effectiveness of this training was assessed in a sample of 59 doctoral students working in the biological and social sciences using a pre–post design with follow-up and a series of ethical decision-making measures serving as the outcome variable. Results showed not only that this training led to sizable gains in ethical decision making but also that these gains were maintained over time. The implications of these findings for ethics training in the sciences are discussed.
