Semantics,experience and time

The computational hypothesis, with its inherent representationalism, and the dynamical hypothesis, with its apparent absence of representations and its commitment to continuous time, stand at an impasse. It is unclear how the dynamical stance can handle representational thought, or how computationalism can deal effectively with a tightly coupled, reciprocally causative agent–environment system in continuous transformation. Underlying this dilemma is the complex relation of mind to time, a relation encoded in the word experience. We must ask if any hypothesis describes a ‘device’ capable of experience? Yet what is an intelligence and its thought without experience? Is a computational device, whether supporting a symbolic processor or connectionist net, intrinsically condemned to a zero degree of experience? What is required of a dynamical device? It is argued here that ‘semantic’ intelligence and thought rests upon experience, fundamentally upon the invariance laws defined over time within conscious perception. The structure of experience is intrinsically unavailable to the computational device, limiting it to a ‘syntactic’ intelligence. An alternative conception of a device is offered, based on Bergson conjoined with Gibson, which supports the qualitative and structural aspects of experience and the semantic. It frames a dynamical model of perception and memory in which invariance laws are intrinsic, creates a deeper notion of situatedness, and supports a concept of semantically based, representative thought founded upon perception.     

Sex steroids and human behavior: implications for developmental psychopathology

In a variety of mammalian species, prenatal androgens organize brain structures and functions that are later activated by steroid hormones in postnatal life. In humans, studies of individuals with typical and atypical development suggest that sex differences in reproductive and nonreproductive behavior derive in part from similar prenatal and postnatal steroid effects on brain development. This paper provides a summary of research investigating hormonal influences on human behavior and describes how sex differences in the prevalences and natural histories of developmental psychopathologies may be consistent with these steroid effects. An association between patterns of sexual differentiation and specific forms of psychopathology suggests novel avenues for assessing the effects of sex steroids on brain structure and function, which may in turn improve our understanding of typical and atypical development in women and men.     

Conceptual and empirical perspectives on the Rorschach assessment of psychopathology

Conceptual and empirical perspectives on the Rorschach assessment of psychopathology are described and placed in a complementary perspective that stresses the value of conceptual formulations and the necessity of empirical data. Empiricism without concepts fails to explain adequately why Rorschach assessment yields useful information; conceptualization without empirical support fails to document adequately the psychometric soundness of Rorschach inferences. Used in tandem, explanatory concepts and supportive data enhance the scientific stature and professional utility of Rorschach assessment.     

Residential crowding experience scale—assessment and validation

The present study was designed to construct and revalidate the Crowding Experience Scale and to investigate its predictive validity. Factor analysis results suggest that perceived crowding is comprised of four components, labelled as spaciousness, positive relationships, negative relationships, and uncontrolled disturbance. The factor-derived perceived crowding subscales showed unique relationships with the outcome variables related to health, well-being, and residential satisfaction. The results provide some indication that perceived crowding mediates the relationship between objective crowding and the dependent measures. The implications of the project are discussed. © 1997 John Wiley & Sons, Ltd.

Implications of empirical Bayes meta-analysis for test validation.

Empirical Bayes meta-analysis provides a useful framework for examining test validation. The fixed-effects case in which rho has a single value corresponds to the inference that the situational specificity hypothesis can be rejected in a validity generalization study. A Bayesian analysis of such a case provides a simple and powerful test of rho = 0; such a test has practical implications for significance testing in test validation. The random-effects case in which sigma2rho > 0 provides an explicit method with which to assess the relative importance of local validity studies and previous meta-analyses. Simulated data are used to illustrate both cases. Results of published meta-analyses are used to show that local validation becomes increasingly important as sigma2rho increases. The meaning of the term validity generalization is explored, and the problem of what can be inferred about test transportability in the random-effects case is described.

Externalizing psychopathology in adulthood: a dimensional-spectrum conceptualization and its implications for DSM-V

Mental disorders involving antisocial behavior and substance use are genetically linked and vary continuously. The authors present a review and integrative conceptualization of these observations in terms of a dimensional and hierarchically organized externalizing spectrum. As a foundation for this conceptualization, the authors introduce a quantitative, model-based approach to comparing categorical and continuous conceptions of psychopathology and apply this approach in an empirical study of patterns of comorbidity among externalizing disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders. The authors present evidence that comorbidity among externalizing disorders is best modeled by an underlying normally distributed continuum of risk for multiple disorders within the externalizing spectrum. The authors conclude by discussing implications of the externalizing spectrum conceptualization for classification of disorders in the upcoming 5th edition of the Diagnostic and Statistical Manual of Mental Disorders.     

Piaget's data and spearman's theory—An empirical reconciliation and its implications for academic achievement

A hierarchical simple structure factor solution was obtained for item scores from a psychometrized battery of Piagetian-type tasks individually administered to 660 kindergarten children. At the first level of factors were the Piagetian theoretical entities of seriation, classification, conservation of number, and temporal and spatial reasoning, with numeration loading on seriation and classification as indicated by the theory. At the second level were two factors identified as Piaget's logicomathematical and infralogical operations. A third-level factor was identified as a g factor. The association of the Piagetian-type tasks with kindergarden and first grade academic achievement was through the third-level g factor. The second-level factors appeared to be similar to Vernon's k:m and v:ed but, like the first level factors, made no important contribution to predicted achievement above that contributed by the g factor. A socioeconomic factor made no unique contribution to predicted first grade achievement. It was concluded that the Piagetian concrete operations variables have no unique role in the prediction of kindergarten or first grade academic achievement.     

Multifactor measurement of bodily feelings: Conceptual development,scale construction,and empirical validation

A series of studies is described demonstrating a coherent exploratory and confirmatory factor-analytic approach to the scaling of self-reported bodily feelings. This approach attempts to optimize the orthogonality, parsimony, and meaningfulness of a multifactor inventory. Psychometric properties of the resulting 35-item Bodily Feeling Scale (BFS) are presented and its comparability with other inventories is discussed. A validity study using item-content-based scales of the Minnesota Multiphasic Personality Inventory showed both concurrent and discriminative validity of the BFS. Implications for clinical and research utility are discussed.Portions of this research were conducted while the first author was supported by a University Graduate Fellowship awarded by the Graduate School of Arts and Sciences at Vanderbilt University.Professor Nunnally passed away in August 1982. His major contributions to the several stages of this research program are recognized through coauthorship.     

Assessment of adult psychopathology: meta-analyses and implications of cross-informant correlations

Assessment of adult psychopathology relies heavily on self-reports. To determine how well self-reports agree with reports by "informants" who know the person being assessed, the authors examined 51,000 articles published over 10 years in 52 peer-reviewed journals for correlations between self-reports and "informants" reports. Qualifying correlations were found in 108 (0.2%) of the articles. When self-reports and informant reports were obtained with parallel instruments, mean cross-informant correlations were .681 for substance use, .428 for internalizing, and .438 for externalizing problems. When based on different instruments, the mean cross-informant correlation was .304. The moderate sizes of the correlations argue for systematically obtaining multi-informant data. National survey findings were used to illustrate practical ways to obtain and use such data.     

The joint structure of maladaptive personality traits and psychopathology

We examined the joint structure of symptoms/syndromes of psychopathology (MMPI-2 Restructured-Clinical Scales; MMPI-2-RC; Tellegen et al., 2003) and maladaptive personality traits (Schedule for Nonadaptive and Adaptive Personality; SNAP-2; Clark, Simms, Wu, & Casillas, 2014) via a series of top-down factor analyses—Goldberg (2006) “bass-ackwards approach”—in a sample of 419 mental-health outpatients and 567 military veterans. A three-factor solution consisting of Negative Affectivity (including Oddity), Low Positive Affectivity, and Disinhibition-versus-Constraint best represented the joint symptom-trait structure, consistent with the third level of Markon et al. (2005) joint hierarchical structure of normal and maladaptive personality traits. Our results point to robustness of the structure of adaptive and maladaptive personality traits and symptoms of psychopathology at the three-factor level.     

The implications of convergent and discriminant validity data for instrument validation

It seems intuitively compelling to many investigators that measurements, on the same subjects by different methods, purportedly of the same given trait are somehow better evidenced to be mutually valid measurements of that trait to the degree that they are intercorrelated. It is similarly compelling that measurements on the same subjects of purportedly different and uncorrelated traits are somehow better evidenced to be valid measurements to the degree that they are not intercorrelated. Further, a demonstration of hetero-method mono-trait intercorrelation (convergence) jointly with one of hetero-method, or preferably mono-method, hetero-trait independence (discrimination) is more compelling than either single demonstration alone [see Campbell & Fiske, 1959]. I hope to show in what follows that this intuition is misleadingunless certain rather demanding prerequisites are satisfied. Then I hope to show that contrary demonstrations are generally too indecisive to consitute validity disconfirmations. Finally, I shall consider some issues in the practical use of the indecisive multitrait-multimethod data.An earlier version of this paper was presented at the Midwestern Society of Multivariate Experimental Psychology meetings of May 1969 in Chicago. Some explication of the concept of measuring instrument has also been presented elsewhere [Krause, 1969].
