Part I: Analysis of Dynamic Categories: Aristotle's Distinction between Change and Activity

Aristotle's conception of being is dynamic. He believes that a thing is most itself when engaged in its proper activities, governed by its nature. This paper explores this idea by focusing on Metaphysics Θ, a text that continues the investigation of substantial being initiated inMetaphysics Z. Q.1 claims that there are two potentiality-actuality distinctions, one concerned with potentiality in the strict sense, which is involved in change, the other concerned with potentiality in another sense, which he says is more useful for the present project. His present project is the investigation of substantial being, and the relevant potentiality is the potentiality for activity, the full manifestation of what a thing is. I explore Aristotle's two potentiality-actuality distinctions AND argue that the second distinction is modeled on the first, with one crucial modification. Whereas a change is brought about by something other than the object or by the object itself considered as other (as when a doctor cures himself), an activity is brought about byte object itself considered as itself. This single modification yields an important difference: whereas a change leads to a state other than the one an object was previously in, an activity maintains or develops what an object already is.     

Reclaiming the Person: Intersectionality and Dynamic Social Categories Through a Psychological Lens

Psychology’s conventionally treatment of individuals’ engagement with and resistance to the societal processes in which they are embedded has come under scrutiny amid the rise of postmodernist and critical feminist perspectives (among many others) in the social sciences. A sample of social psychology’s responses to these critiques is presented in the recently published book, Social Categories in Everyday Experience edited by Shaun Wiley et al. (2011). In this essay, the challenges of seriously addressing the critiques of psychology’s conventional treatment of social categories, which implicate fundamental assumptions of the discipline, are discussed. Further, it is argued that in order to effectively construct psychological accounts of political activism and social change amid theories that are increasingly cognizant of the complexities and contingencies of social embeddiness, the person must be reclaimed and revisioned. Notions of agency that complement an intersectional and systemic vision of the social world are discussed.     

Integral Constructivism and Dynamic Systems in Psychotherapy Processes

This article presents a brief overview of the metatheory of integral constructivism, highlighting important convergences among constructivist, dynamic systems, integral, object relations, self-psychology, and intersubjective approaches to the practice of psychotherapy. The roles of relationships, emotionality, and perturbations in the client-therapist bond are emphasized. Complex nonlinear dynamics are inherent to life organization and to therapeutic process.     

Dynamic Interracial/Intercultural Processes: The Role of Lay Theories of Race

ABSTRACT This paper explores how the lay theory approach provides a framework beyond previous stereotype/prejudice research to understand dynamic personality processes in interracial/ethnic contexts. The authors conceptualize theory of race within the Cognitive–Affective Personality System (CAPS), in which lay people's beliefs regarding the essential nature of race sets up a mind-set through which individuals construe and interpret their social experiences. The research findings illustrate that endorsement of the essentialist theory (i.e., that race reflects deep-seated, inalterable essence and is indicative of traits and ability) versus the social constructionist theory (i.e., that race is socially constructed, malleable, and arbitrary) are associated with different encoding and representation of social information, which in turn affect feelings, motivation, and competence in navigating between racial and cultural boundaries. These findings shed light on dynamic interracial/intercultural processes. Relations of this approach to CAPS are discussed.     

Categories and causality: the neglected direction

The standard approach guiding research on the relationship between categories and causality views categories as reflecting causal relations in the world. We provide evidence that the opposite direction also holds: categories that have been acquired in previous learning contexts may influence subsequent causal learning. In three experiments we show that identical causal learning input yields different attributions of causal capacity depending on the pre-existing categories to which the learning exemplars are assigned. There is a strong tendency to continue to use old conceptual schemes rather than switch to new ones even when the old categories are not optimal for predicting the new effect, and when they were motivated by goals that differed from the present context of causal discovery. However, we also found that the use of prior categories is dependent on the match between categories and causal effect. Whenever the category labels suggest natural kinds which can be plausibly related to the causal effects, transfer was observed. When the categories were arbitrary, or could not be plausibly related to the causal effect learners abandoned the categories, and used different categories to predict the causal effect.     

Categories and Dimensions

ABSTRACT— The distinction between categories and dimensions has important consequences for basic and applied science in many areas of psychological research. Decisions as to whether individuals should be assigned to groups or located along one or more continua often are based on personal preferences or discipline-specific measurement traditions, which can lead to the creation, use, or reification of spurious categories or dimensions. Methods for evaluating the latent structure of psychological constructs, using powerful and informative tests between competing models, are available. Rather than choosing on a priori grounds, investigators can perform structural research to evaluate the strength and consistency with which results tease apart categorical and dimensional models. Here, we review why researchers should make this distinction empirically, briefly discuss methods available for doing so, and describe the breadth of areas ripe for exploiting the largely untapped potential of structural research.     

An Investigation of the Dynamic Processes Promoting Citizen Participation

This study expanded the citizen participation literature by examining the dynamic nature of citizen participation and the extent to which the factors associated with citizen participation may be moderated by resident leadership status. Longitudinal survey data collected from 542 residents in one small Midwestern city implementing a community change initiative provide some insight into the challenges surrounding the promotion of an active citizenry. Within this one community, citizenship behaviors of emergent resident leaders and residents uninterested in a leadership role were influenced, to some extent, by different factors and the importance of these factors shifted in only a 2 years time span. Future research is needed to determine if the dynamics uncovered in this study were due to the initiative or to the nature of citizen participation processes.

Legal Risk in Selection: An Analysis of Processes and Tools

Purpose

This paper reviews a decade of employment litigation to illuminate the most legally dangerous selection devices and employment practices.

Design/Methodology/Approach

A sample (n = 312) of court cases drawn from 10 years of Bloomberg BNA case briefs was analyzed to determine which selection tools (e.g., biographical information blank, interview, cognitive ability test, and psychomotor test) and which selection processes (e.g., violations of the four-fifths rule, administrative inconsistencies, lack of documentation, failure to provide accommodations) are most at risk for litigation for unfair employment practices.

Findings

Results demonstrate that while some selection tools do attract legal scrutiny, dangerous hiring practices such as favoritism against protected classes and improper human resource documentation put employers at far greater risk of suit. When considering cases settled outside of court and those that continued to trial, the data reveal that employers lose employment discrimination cases at a rate nearing 90 % and suffer an average payout of over $1.5 million per case.

Implications

Just as legal challenges once drove the search for selection tools free of adverse impact, the current legal landscape demonstrates the necessity of fair and consistent selection processes. This paper provides evidence of common mistakes in implementing selection systems—mistakes that lead to costly legal battles.

Originality/Value

This paper reduces cumbersome legal records into useful evidence of trends in recent employment law cases. Selection system designers and organizations who implement them will benefit from avoiding the risky hiring practices presented in this paper.     

Categories and continua: a review of taxometric research

The taxometric procedures developed by Paul Meehl and his colleagues have been used in a large body of research seeking to distinguish between categorical and continuous models of latent variables. In this article the authors survey taxometric studies of psychopathological, personality, and other variables and draw conclusions about the taxonicity of latent variables in these domains. In addition, the authors review research on the validation and refinement of taxometric methods and make proposals for improving the application of taxometric research. The authors consider questions that remain about the conceptual status of taxometrics and raise new ones. They show that taxometric methodology has made an accelerating number of contributions to psychological research, has resolved several longstanding controversies, and has challenged some entrenched theoretical assumptions in differential psychology. Moreover, they contend that the research possibilities that it affords have yet to be fully exploited.     

Gender and Other Categories

In my discussion of Bordo's paper I leave aside the particulars of her detailed critique of Grimshaw and the issue of the “maleness” of philosophy and focus instead on some questions raised by her analysis of heterogeneity and generality. I find this analysis very persuasive, particularly her counterarguments to the “theoretics of heterogeneity.” However, 1 am less persuaded by her concluding points and suggestions for future directions.     

Categories and Levels of Reality

The discussion of the relation of levels of reality to categories is important because categories have often been interpreted as constituting levels of reality. This article explores whether this view is correct, and argues it is not. Categories as such should not be understood to constitute levels of reality, although particular categories may. The article begins with a discussion of levels of reality and then turns to specific questions about categories and how they are related to these levels.     

Categories of Competition

In the first part of this paper, I argue that philosophers of sport have mistakenly privileged a specific psychology and purpose in their definitions of competition. The result of this mistake has been that philosophers of sport make generalisations about competition as such which in fact only hold for some competitions. In the second and third parts of the paper, I articulate an alternative approach: rather than search for a single psychology and purpose that underlies all competition, I argue that we should begin by acknowledging four distinctly different competitive formats, and only then enquire as to which psychologies and purposes are more or less appropriate to each format. This method allows us to capture the richness and diversity of competition, and helps to ensure that we do not confuse part and whole when defining it.     

Categories and percepts: a bi-directionnal framework for categorization

Categorization is a fundamental process whereby variable perceptual inputs are reduced progressively to a small number of equivalence classes, called 'categories'. How do theorists frame the categorization problem so that variable face, object and scene information is stabilized for higher-level processing? One approach suggests that perception delivers a fixed set of features that are treated as inputs to categorization processes. This paper questions this unidirectionality and argues instead that perceptual organization is linked intimately with the categorization being accomplished. An example is presented where it can be shown that the history of categorization changes the featural analysis and the perception of identical, but unfamiliar, inputs. Flexible percepts are then generalized to real-world scene categorization in the space of multiple spatial scales. This evidence suggests that a bidirectional framework, with direct interactions between concepts and percepts, is a more appropriate framework for categorization.     

Cluster Analysis Examination of Serial Killer Profiling Categories: A Bottom‐Up Approach

Two studies explored the validity of dichotomous classification of organised/disorganised serial killers and the four typologies (visionary, mission, hedonistic, and power/control) adopted by the Federal Bureau of Investigation (FBI). Tables documenting crime scene criteria were devised consisting of 50 typifying different crime scenes (Study 1) and 48 crime scenes (taken from the 50 crime scene criteria) with a further 10 motive‐based crime scene criteria (Study 2). Adopting content analysis, crime scenes depicted for 40 (Study 1) and 40 (Study 2) serial killers using secondary sources of data were dichotomously coded for the presence or absence of the crime scene criteria. These data were inputted for agglomerative hierarchical cluster using Ward's method as the clustering algorithm. Differences in the nature of clusters were found for male and female serial killers; however, there was no empirical support for the organised/disorganised classifications or the four typologies. The ‘bottom‐up’ approach resulted in clusters from the different crime scene criteria that helped to understand how these criteria were associated within the serial killer cohort considered. It is concluded that the resulting clusters in both studies support the notion of there being an underlying organised element to most serial murder and that serial murders differ according to the nature of disorganised crime scene criteria present.

Cross-Sectional Analysis of Longitudinal Mediation Processes

Statistical mediation analysis can help to identify and explain the mechanisms behind psychological processes. Examining a set of variables for mediation effects is a ubiquitous process in the social sciences literature; however, despite evidence suggesting that cross-sectional data can misrepresent the mediation of longitudinal processes, cross-sectional analyses continue to be used in this manner. Alternative longitudinal mediation models, including those rooted in a structural equation modeling framework (cross-lagged panel, latent growth curve, and latent difference score models) are currently available and may provide a better representation of mediation processes for longitudinal data. The purpose of this paper is twofold: first, we provide a comparison of cross-sectional and longitudinal mediation models; second, we advocate using models to evaluate mediation effects that capture the temporal sequence of the process under study. Two separate empirical examples are presented to illustrate differences in the conclusions drawn from cross-sectional and longitudinal mediation analyses. Findings from these examples yielded substantial differences in interpretations between the cross-sectional and longitudinal mediation models considered here. Based on these observations, researchers should use caution when attempting to use cross-sectional data in place of longitudinal data for mediation analyses.
