The Epistemic Integrity of Scientific Research

We live in a world in which scientific expertise and its epistemic authority become more important. On the other hand, the financial interests in research, which could potentially corrupt science, are increasing. Due to these two tendencies, a concern for the integrity of scientific research becomes increasingly vital. This concern is, however, hollow if we do not have a clear account of research integrity. Therefore, it is important that we explicate this concept. Following Rudolf Carnap’s characterization of the task of explication, this means that we should develop a concept that is (1) similar to our common sense notion of research integrity, (2) exact, (3) fruitful, and (4) as simple as possible. Since existing concepts do not meet these four requirements, we develop a new concept in this article. We describe a concept of epistemic integrity that is based on the property of deceptiveness, and argue that this concept does meet Carnap’s four requirements of explication. To illustrate and support our claims we use several examples from scientific practice, mainly from biomedical research.     

Clinical Interviewing With Older Adults

Over the next few decades the older adult population will increase dramatically, and prevalence rates of psychiatric disorders are also expected to increase in the elderly cohort. These demographic projections highlight the need for diagnostic instruments and methods that are specifically tailored to older adults. The current paper discusses the benefits and drawbacks of clinical interviewing with older adults, using two popular interview protocols as illustrative examples. Drawing upon preexisting basic research and our own observations collected in clinical and research settings over a 10-year period, we suggest procedures and suggestions for augmenting existing interview protocols to increase their usefulness with older adults in research and clinical settings. Strategies to optimize interview duration and enhance retrospective data accuracy and the pros and cons of dimensional versus dichotomous response formats, among other relevant topics, are discussed.     

QUANTUM AND CONSCIOUSNESS: IN SEARCH OF A NEW PARADIGM

Abstract. Two fundamental issues raised by Lothar Schäfer are considered: (1) the question of a suitable paradigm within which the findings of quantum physics can be optimally interpreted and (2) the question of the assessment of the presence and importance of mind and consciousness in the universe. In regard to the former, I contend that the ideal of science is to interpret its findings in an optimally consistent and minimally speculative framework. In this context Schäfer's assertion that certain findings in quantum physics (those that relate to virtual states) indicate the presence of mind at the quantum level implies a dualistic and hence unnecessarily speculative assumption. In regard to the assessment of mind and consciousness, a consistent and parsimonious paradigm suggests that mind and consciousness are not part of a chain of events consisting of an admixture of physical and mental events but that physical events form a single, coherent set of events, and mental events another set, with the two sets related, as Teilhard (and a number of other philosophers, including White head) affirmed, as the “within” and the “without” (or the “mental pole” and the “physical pole”) of one and the same fundamental reality. This panpsychist as contrasted with Schäfer's dualist paradigm provides a single self‐consistent framework for the interpretation of quantum (and all natural) events while recognizing the presence of mind in the universe as the least speculative realist implication of our immediate experience of consciousness.     

The performance of a simple motor task with kinaesthetic sense loss

Two related studies were carried out, to test the suitability of the nerve compression block as a technique in the investigation of kinaesthesis in motor skills.

In both studies a key tapping task was used. Each experimental group was composed of six volunteer subjects. It was found that kinaesthetic sensation was eliminated after pressure had been applied for 20-25 min., but muscle power was not seriously affected at this stage of the block. The results also showed a pronounced performance decrement in the absence of kinaesthetic feedback, and that this decrement was not due to emotional or other disturbances caused by the experimental procedure. The loss of tactile sensation was also observed.     

Perception of movement patterns: tracking of movement

The tracking of complex two-dimensional movement patterns was studied. Subjects were blindfolded, and their right hand moved around stencil patterns in the midsagittal plane, while the left hand concurrently reproduced the right-hand movement. The accuracy with which the left hand shadowed the criterion movements of the right hand was measured in shape and size. Right-hand movements were active or passive. Present tracking performance was contrasted with errors in recall reported by Bairstow and Laszlo (1978). Results showed that tracking performance was accurate. Active and passive criterion movements were tracked differently. Tracking was clearly superior to recall performance.     

RELIGION VERSUS SCIENCE: THE CONFLICT IN REFERENCE TO TRUTH VALUE,NOT CASH VALUE

Abstract. The rift between science and religion needs to be assessed not merely on pragmatic grounds, on the basis of the effect of scientific versus religious beliefs on people's behavior, as John Caiazza's essay does, but also and above all in regard to the cogency of the respective beliefs in reference to what we can reasonably assume is the true face of reality. About such truth value, the conflict is not irremediable; there are elements of belief regarding the nature of reality that are strikingly similar regardless of whether one arrived at them on the basis of faith in revealed knowledge or on the basis of knowledge acquired by reasoning from or in reference to experience. Two such items are selected here by way of example: belief that in certain states of mind and consciousness individuals can experience union with something larger or deeper than themselves, and belief that the universe we inhabit is the result of an original creative act.     

Relationships between event‐related potentials and behavioral and scholastic measures of reading ability: A large‐scale,cross‐sectional study

In the cognitive, computational, neuropsychological, and educational literatures, it is established that children approach text in unique ways, and that even adult readers can differ in the strategies they bring to reading. In the developmental event‐related potential (ERP) literature, however, children with differing degrees of reading ability are, the majority of the time, placed in monolithic groups such as ‘normal’ and ‘dyslexic’ (e.g. Araújo et al., 2012) and analyzed only at the group level. This is likely done due to methodological concerns – such as low sample size or a lack of statistical power – that can make it difficult to perform analysis at the individual level. Here, we collected ERPs and behavior from > 100 children in grades pre‐K–7, as they read unconnected text silently to themselves. This large sample, combined with the statistical power of the Linear Mixed Effects Regression (LMER) technique, enables us to address individual differences in ERP component effects due to reading ability at an unprecedented level of detail. Results indicate that it is possible to predict reading‐related report card scores from ERP component amplitudes – especially that of the N250, a component pertaining to sublexical processing (including phonological decoding). Results also reveal relationships between behavioral measures of reading ability and ERP component effects that have previously been elusive, such as the relationship between vocabulary and N400 mean amplitude (cf. Henderson et al., 2011). We conclude that it is possible to meaningfully examine reading‐related ERP effects at the single subject level in developing readers, and that this type of analysis can provide novel insights into both behavior and scholastic achievement.     

Complex movement patterns: Learning retention and sources of error in recall

In this study of kinaesthesis, the learning, retention, and recall of complex patterns was examined. Subjects were blindfolded, held a stylus in the right hand, and moved around stencil patterns, either actively or passively. The patterns were recalled with a free active movement of the right hand, after various amounts of practice, immediately or after a 60-s interval, once or twice in succession, with and without visual guidance. The shape and size of the drawings was compared with the criterion patterns. The effect of practice varied depending on whether the criterion movement was active or passive, and on the measure of recall performance. Even when the criterion patterns were freely practised, the recall traces showed large errors in shape and systematic shrinkage in size, and there were large individual differences. Regardless of these errors, recall performance was reliable. The effect of an unfilled retention interval varied as a function of practice. When the patterns were recalled under visual guidance, there was no shrinkage in the size of the drawings.
