Subjectivity in Descartes and Kant

Kant's response to Cartesian scepticism is often characterized in the following way. Whereas Descartes drives a wedge between subjective experience and objective reality, Kant argues that there could be no such thing as experience at all if reality were not itself structured in just the way our thought about it is structured. This picture of Kant's response to Descartes portrays him as succeeding, where Descartes fails, in arguing directly from the nature of experience to the nature of reality; as subscribing, therefore, to Descartes' view that one is immediately aware only of one's own mental states, but as seeing a way out of the subjective predicament. I maintain that this picture is deeply flawed. Kant's transcendental argument is in fact a thoroughgoing critique of Descartes' subjectivism, and destroys the Cartesian barrier to recognizing that our awareness of reality is unmediated and direct.     

Nominal scale agreement among observers

Experiments are considered where each of a sample of subjects is assigned to one of C categories separately by each of a fixed or varying group of observers. Building on earlier publications, general procedures are proposed to analyze agreements and disagreements among observers. In the case of a varying group of observers, it is shown that it is not necessary to demand a constant number of observers per subject. In the case of a fixed group of observers, the problem of missing data is considered.The procedures are illustrated within the context of two clinical diagnosis examples. In the first example it is investigated which categories are relatively hard to distinguish from one another; a new theorem is applied that shows a useful property of the statistic kappa. In the second example it is investigated if a subgroup of observers can be found with a significantly higher degree of interobserver agreement.The author gratefully acknowledges the valuable suggestions by W.

A rationale for minimizing distortion in personality questionnaire keys

A rationale and a procedure for constructing questionnaire keys so as to minimize the effect of distortion or faking by the respondents is developed. This rationale is based on the supposition that suppressor items can be identified to reduce distortion in, and thus add to, the validity of questionnaire keys. The procedure is designed primarily for application to the construction of forced choice items.The results of an empirical test of the efficicacy of the forced choice pairing procedure developed as a consequence of this rationale are presented. A key based on forced choice pairs developed by this procedure gave a validity of .33; a second key based on forced choice pairs developed by more conventional procedures gave a validity of .23.The opinions expressed are those of the author and are not to be construed as reflecting official Department of the Army policy. The rationale presented herein was developed and used in an Army research program concerned with the selection of ROTC cadets. In substance, the content of this paper is contained in PRS Report 868,A rationale for minimizing distortion in personality questionnaire keys.     

An approach to the problem of differential prediction

A procedure for maximizing selective efficiency is developed for application to situations in which it is desired to select from a single group of applicants for several possible assignments. The problem of comparable units for the several criteria whose values must be compared to each other for differential assignment purposes is discussed. It is demonstrated that, assuming linear regressions, maximal selection is obtained if individuals in any given assignment are differentiated from those rejected according to critical rejection scores on the multiple weighted sum of the predictors and from another possible assignment by critical difference scores which are merely the differences between the two critical rejection scores. Since the relationships just indicated give no way of determining the magnitude of the critical scores required to select the required number of persons for each assignment, a successive approximation procedure for accomplishing this purpose has been devised and a computational example is worked out.The opinions expressed are those of the author and are not to be construed as official or as those of the War Department.     

Cross-cultural replication of the five-factor model and comparison of the NEO-PI-R and MMPI-2 PSY-5 scales in a Dutch psychiatric sample

The authors investigated cross-cultural replicability of the five-factor model (FFM) of personality as represented by the revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992) in a sample of 423 Dutch psychiatric patients. Also, NEO-PI-R domain scales were compared with the Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) scales of the Minnesota Multiphasic Personality Inventory-2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 2002). Principal-components analysis with procrustean rotation confirmed the hypothesized structural similarity of the present sample with the U.S. normative factor scores. All of the hypothesized relations between NEO-PI-R and PSY-5 scales were confirmed. The results provide evidence for cross-cultural replicability of the FFM and for validity of the NEO-PI-R and PSY-5 constructs in the psychological assessment of psychiatric patients.     

Order-Constrained Solutions in <Emphasis Type="Italic">K</Emphasis>-Means Clustering: Even Better Than Being Globally Optimal

This paper proposes an order-constrained K-means cluster analysis strategy, and implements that strategy through an auxiliary quadratic assignment optimization heuristic that identifies an initial object order. A subsequent dynamic programming recursion is applied to optimally subdivide the object set subject to the order constraint. We show that although the usual K-means sum-of-squared-error criterion is not guaranteed to be minimal, a true underlying cluster structure may be more accurately recovered. Also, substantive interpretability seems generally improved when constrained solutions are considered. We illustrate the procedure with several data sets from the literature.     

Color and context: An ERP study on intrinsic and extrinsic feature binding in episodic memory

Episodic memory for intrinsic item and extrinsic context information is postulated to rely on two distinct types of representation: object and episodic tokens. These provide the basis for familiarity and recollection, respectively. Electrophysiological indices of these processes (ERP old-new effects) were used together with behavioral data to test these assumptions. We manipulated an intrinsic object feature (color; Experiment 1) and a contextual feature (background; Experiments 1 and 2). In an inclusion task (Experiment 1), the study-test manipulation of color affected object recognition performance and modulated ERP old-new effects associated with both familiarity and recollection. In contrast, a contextual manipulation had no effect, although both intrinsic and extrinsic information was available in a direct feature (source memory) test. When made task relevant (exclusion task; Experiment 2), however, context affected the ERP recollection effect, while still leaving the ERP familiarity effect uninfluenced. We conclude that intrinsic features bound in object tokens are involuntarily processed during object recognition, thus influencing familiarity, whereas context features bound in episodic tokens are voluntarily accessed, exclusively influencing recollection.
