Combined effects of inversion and feature removal on N170 responses elicited by faces and car fronts

The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which becomes salient when the face configuration is disrupted. Here we tested whether similar effects could be observed with non-face objects that are structurally similar to faces in terms of possessing a homogeneous within-class first-order feature configuration. We presented upright and inverted pictures of intact car fronts, car fronts without lights, and isolated lights, in addition to analogous face conditions. Upright cars elicited substantial N170 responses of similar amplitude to those evoked by upright faces. In strong contrast to face conditions however, the car-elicited N170 was mainly driven by the global shape rather than the presence or absence of lights, and was dramatically reduced for isolated lights. Overall, our data confirm a differential influence of the eye region in upright and inverted faces. Results for car fronts do not suggest similar interactive encoding of eye-like features and configuration for non-face objects, even when these objects possess a similar feature configuration as faces.     

The stability of a double-slab configuration of two-phase particles confined in a third phase

The stability of a double-slab configuration of two-phase particles confined in a third phase is studied as a function of shape in two and three dimensions. The condition of stability against splitting one phase in the particle into two separate identical slabs is shown to be the sum of the wetting factor and the change in the interface area relative to the shape of the two-phase particle. It is found that the double-slab configuration can be stable for a wide range of wetting factors and shapes.     

Unrealistic vocational choice: A research model

Multimethod factor scores were derived from measures of ACT aptitude, ACT nonacademic achievement and the Omnibus Personality Inventory. A sample of 89 subjects whose freshman major was engineering and whose junior year major consisted of a variety of nonengineering subjects represented subjects who had made an unrealistic vocational choice as freshmen. The junior year majors of these subjects were classified by Holland's theory of vocational choice and the relationship between the factor scores and Holland categories was shown by the technique of spatial configuration. These data were employed to illustrate how counseling practice could be integrated with vocational theory.     

A General Setting for Dedekind's Axiomatization of the Positive Integers

A Dedekind algebra is an ordered pair (B, h), where B is a non-empty set and h is a similarity transformation on B. Among the Dedekind algebras is the sequence of the positive integers. From a contemporary perspective, Dedekind established that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable. The purpose here is to show that this seemingly isolated result is a consequence of more general results in the model theory of second-order languages. Each Dedekind algebra can be decomposed into a family of disjoint, countable subalgebras called the configurations of the algebra. There are ?₀ isomorphism types of configurations. Each Dedekind algebra is associated with a cardinal-valued function on ω called its configuration signature. The configuration signature counts the number of configurations in each isomorphism type that occurs in the decomposition of the algebra. Two Dedekind algebras are isomorphic iff their configuration signatures are identical. The second-order theory of any countably infinite Dedekind algebra is categorical, and there are countably infinite Dedekind algebras whose second-order theories are not finitely axiomatizable. It is shown that there is a condition on configuration signatures necessary and sufficient for the second-order theory of a Dedekind algebra to be finitely axiomatizable. It follows that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable.     

Factors in the learning behavior of the albino rat

The table of intercorrelations published by Dr. R. L. Thorndike in theGenetic Psychology Monographs, 1935,17, No. 1, has been reanalyzed into ten factors. Rotation of the reference vectors resulted in a configuration which, for all practical purposes, may be said to show a simple structure and (except for one variable on one factor) a positive manifold. Five of the factors can be interpreted with some confidence, one only with considerable caution; three factors are specific to the apparatus employed, and for the one remaining factor, no interpretation is attempted; it appears to be a residual plane.     

Further evidence that the family assessment device should be reorganized: response to Miller and colleagues

Ridenour, Daley, and Reich's (1999) factor analyses of the Family Assessment Device (FAD) indicated that the FAD be reorganized. Miller and colleagues (2000) contend that the FAD be used in its original format based on the FAD's theoretical foundation; however, this does not preclude the importance of scientific scrutiny of an instrument's construct validity to determine how well an instrument represents its theoretical base. Subscale factor analyses (exploratory and confirmatory), item-level factor analysis, and the clinical and psychometric studies cited by Miller and colleagues suggest a more parsimonious FAD configuration and were consistent with Ridenour and colleagues' factor analyses.     

Subjective geographic distance: A multidimensional comparison

The interdistances between thirteen places situated in different parts of the world were estimated by 60 subjects. The estimates were analysed by Kruskal's multidimensional technique and, after a cosine transformation, by factor analysis. It was found that both methods yielded the same three-dimensional solution. Also a two-dimensional configuration could describe the data, and it was shown that this configuration contained representations of unidimensional ratings obtained in other studies. This investigation was supported by grants from the Bank of Sweden Tercentenary Fund and the Swedish Council for Social Science Research. Died 5 May 1971.     

Confirmatory Factor Analysis of the Behavior Rating Inventory of Executive Function (BRIEF) in a Clinical Sample

Evidence for the validity of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) based on internal structure was examined in a sample of children with mixed clinical diagnoses via maximum likelihood confirmatory factor analysis. Four alternative factor models of children's executive function, based on current theories that posit a unidimensional versus fractionated model (Rabbitt, 1997; Shallice & Burgess, 1991), using the revised 9-scale BRIEF configuration that separates two components of the Monitor scale, were examined for model fit. A 3-factor structure best modeled the data when compared directly with 1-, 2-, and 4-factor models. The 3-factor model was defined by a Behavior Regulation factor consisting of the BRIEF Inhibit and Self-Monitor scales, an Emotional Regulation factor consisting of the Emotional Control and Shift scales, and a Metacognition factor composed of the Working Memory, Initiate, Plan/Organize, Organization of Materials, and Task-Monitor scales. The findings support a fractionated, multi-component view of executive function as measured by the BRIEF.     

Multidimensional analysis of complex structure: Mixtures of class and quantitative variation

For certain kinds of structure consisting of quantitative dimensions superimposed on a discrete class structure, spatial representations can be viewed as being composed of two subspaces, the first of which reveals the discrete classes as isolated clusters and the second of which contains variation along the quantitative attributes. A numerical method is presented for rotating a multi-dimensional configuration or factor solution so that the first few axes span the space of classes and the remaining axes span the space of quantitative variation. The use of this method is then illustrated in the analysis of some experimental data.The author is particulary indebted to Dr. W. S. Torgerson for many valuable suggestions. In addition, Mr. M. David Todd and Mr. Joseph Young provided technical assistance in developing several assembly language routines, and Dr. James E. Deese made a number of helpful comments. This research was undertaken in partial fulfillment of the doctoral requirements at Johns Hopkins University, and was financed in part by the National Science Foundation.

The linguistic and embodied nature of conceptual processing

Recent theories of cognition have argued that embodied experience is important for conceptual processing. Embodiment can be contrasted with linguistic factors such as the typical order in which words appear in language. Here, we report four experiments that investigated the conditions under which embodiment and linguistic factors determine performance. Participants made speeded judgments about whether pairs of words or pictures were semantically related or had an iconic relationship. The embodiment factor was operationalized as the degree to which stimulus pairs were presented in the spatial configurations in which they usually occur (i.e., an iconic configuration, e.g., attic presented above basement). The linguistic factor was operationalized as the frequency of the stimulus pairs in language. The embodiment factor predicted error rates and response time better for pictures, whereas the linguistic factor predicted error rates and response time better for words. These findings were modified by task, with the embodiment factor being strongest in iconicity judgments for pictures and the linguistic factor being strongest in semantic judgments for words. Both factors predicted error rates and response time for both semantic and iconicity judgments. These findings support the view that conceptual processing is both linguistic and embodied, with a bias for the embodiment or the linguistic factor depending on the nature of the task and the stimuli.     

Representation of facial expressions of emotion

Inversion interferes with the encoding of configural and holistic information more than it does with the encoding of explicitly represented and isolated parts. Accordingly, if facial expressions are explicitly represented in the face representation, their recognition should not be greatly affected by face orientation. In the present experiment, response times to detect a difference in hair color in line-drawn faces were unaffected by face orientation, but response times to detect the presence of brows and mouth were longer with inverted than with upright faces, independent of the emergent expression (neutral, happy, sad, and angry). Expressions are not explicitly represented; rather, they and the face configuration are represented as undecomposed wholes.

Spatial information with pictures and words in visual short-term memory

In a delayed matching task, the influence of spatial congruence between study and test on visual short-term memory for geometric figures and words was investigated. Subjects processed series of pictures which showed three words or three geometric figures arranged as rows or as triangular configurations. At test, the elements were presented in the identical or in the alternative configuration as at study. In the non-matching case, one of the studied elements was exchanged. The delay was 5 s. Subjects judged whether the elements were the same as during study, independent of their configuration. In Exp. 1, pictures of figures and words were mixed within one list. For both modalities, the response times were longer if the configuration at test was incongruent to the one at study. This contradicts the results of Santa, who observed effects of spatial congruency for figures, but not for words. In Exp. 2 we therefore presented the same material as in Exp. 1, but now the lists were modality-pure, as in the experiment of Santa – i.e., words and figures were shown in different lists. This time, spatial incongruency impaired recognition of the figures, but not recognition of the words. These results show that in a non-verbal context, isolated visually presented words are spatially encoded as non-verbal stimuli (figures) are. However, the word stimuli are encoded differently if the task is a pure verbal one. In the latter case, spatial information is discarded. Received: 9 September 1997 / Accepted: 30 March 1998     

Identity configurations: a new perspective on identity formation in contemporary society

This paper deals with the theoretical construct of "identity configuration." It portrays the different possible ways in which individuals configure the relationship among potentially conflicting identifications in the process of identity formation. In order to explicate these configurations, I analyzed narratives of identity development retold by individuals describing personal identity conflicts that arise within a larger context of sociocultural conflict. Thirty Jewish modern orthodox young adults were interviewed regarding a potentially conflictual identity issue (i.e. their religious and sexual development). Their deliberations, as described in the interviews, were examined, and four different configurations were identified: a configuration based on choice and suppression; an assimilative and synthesizing configuration; a confederacy of identifications; and a configuration based on the thrill of dissonance. The different configurations are illustrated through exemplars, and the possible implications of the concept of "configuration" for identity theory are discussed.     

The item structure of the Eysenck Personality Questionnaire across method and culture

Since its publication, the Eysenck Personality Questionnaire (EPQ) has endured much criticism of its psychometric properties. As the most stringent of these attacks has derived from hierarchical factor analytic studies it is reasonable to ask whether the inadequacies reported accrue to the questionnaire itself or to the problematic features of factor analysis as a method. A further feature of empirical studies that are critical of the EPQ is that they are, by-and-large, based upon non-British samples. As the EPQ was constructed in Britain it is quite conceivable that cultural artifacts are responsible for the inconsistent findings of Canadian and American researchers. This paper offers a brief review of some of the critical research and reports a study in which the item structure of the EPQ is explored by non-metric multidimensional scaling techniques upon a sample of Irish adolescents. The MDS configuration was then compared with the higher order factor analytic results of American researchers to examine invariance across method. A clear item structure emerges supporting the Eysencks' theoretical model although items of the P scale are less homogenous than would be ideal for a psychometric tool.     

An entire life in one glance: a psychoanalytic reading of Revolutionary Road

This article, starting from an analysis of the film Revolutionary Road (2009; director, Sam Mendes), addresses the topic of conflictuality in relationships between couples, especially in those characterized by intense violence and a relational configuration of the sadomasochistic type. In particular, the film – in highlighting sequential moments in the couple’s life, from its formation through to its tragic conclusion – seems to strengthen the hypothesis that the specific quality of falling in love is a contributing factor in determining the dramatic unfolding of a couple’s relationship. The relationship is characterized by an experience of intense, erotic sensoriality, and by the nature of the unconscious fantasy underlying the bond between the couple that began with the moment of falling in love, a bond in which deep needs for fusion predominate. The presence of this neediness impedes a more adequate working through of the conflicts and the transition to more satisfying ways of relating.     

Understanding Psychopathy Using the Basic Elements of Personality

Psychopathy is a form of personality disorder characterized by arrogance, self‐absorption, callousness, exploitation, and impulsivity that is also strongly associated with antisocial behavior. The present paper argues that psychopathy can and should be understood as a configuration of personality traits from a general model of personality functioning – the five‐factor model (FFM). In this paper, we demonstrate that previous theoretical conceptualizations of psychopathy and current empirical ones converge on a general FFM profile characterized by very low scores on agreeableness and conscientiousness and mixed relations to aspects of neuroticism and extraversion. Further, we articulate the advantages to understanding psychopathy in this way. The FFM provides an assay of extant inventories, explains the factor structure of various inventories, accounts for the epidemiology of psychopathy, and makes sense of the litany of putative psychopathic deficits. Perhaps most importantly, the FFM provides a connection to basic research in personality.     

The effect of occlusion on the semantics of projective spatial terms: a case study in grounding language in perception

Although data-driven spatial template models provide a practical and cognitively motivated mechanism for characterizing spatial term meaning, the influence of perceptual rather than solely geometric and functional properties has yet to be systematically investigated. In the light of this, in this paper, we investigate the effects of the perceptual phenomenon of object occlusion on the semantics of projective terms. We did this by conducting a study to test whether object occlusion had a noticeable effect on the acceptance values assigned to projective terms with respect to a 2.5-dimensional visual stimulus. Based on the data collected, a regression model was constructed and presented. Subsequent analysis showed that the regression model that included the occlusion factor outperformed an adaptation of Regier & Carlson’s well-regarded AVS model for that same spatial configuration.     

Coordination of Grip Configurations as a Function of Force Output

In this investigation, the authors examined the coordination and control of force production by the digits of the hand as a function of criterion force level and grip configuration. Each adult participant (N = 6: 3 men and 3 women) was required to place the thumb and a finger (or fingers) upon load cells that were fixed to a grasping apparatus that was clamped to a table. In the task, participants had to match a criterion continuous constant total force level displayed on a computer screen. There were 10 trials at each grip configuration and criterion force level combination on each of 3 consecutive days. The results showed that (a) different grip configurations minimized error at each force level; (b) there was a specific digit pairing within a given grip configuration that produced the highest correlation of force output; (c) the correlation between the force output of digits generally increased at higher force levels; (d) error was reduced at each force level and grip configuration over the practice period; and (e) the organization of the force output of each digit varied as a function of digit, force level, grip configuration, and practice. The findings are consistent with the hypothesis that coordination of the digits in prehension is reflective of an adaptive, task-specific solution that is modified with practice.
