Explanation versus accommodation: Reply to Bowers (2010)

Bowers (2010) presented a critique of the account of masked priming presented by Norris and Kinoshita (2008) based on the Bayesian Reader model of visual word recognition (Norris, 2006). In this reply, we point out that: (1) Bowers' criticisms are based on his misunderstanding of both the Bayesian or ideal-observer approach, and the theoretical claims made in Norris and Kinoshita, and (2) Bowers' alternative account of the key data presented in Norris and Kinoshita relies on a series of ad hoc assumptions that are combined in different proportions to postdict any pattern of data.     

A methodological investigation of the Intermodal Preferential Looking paradigm: Methods of analyses,picture selection and data rejection criteria

The Intermodal Preferential Looking paradigm provides a sensitive measure of a child's online word comprehension. To complement existing recommendations (Fernald, Zangl, Portillo, & Marchman, 2008), the present study evaluates the impact of experimental noise generated by two aspects of the visual stimuli on the robustness of familiar word recognition with and without mispronunciations: the presence of a central fixation point and the level of visual noise in the pictures (as measured by luminance saliency). Twenty-month-old infants were presented with a classic word recognition IPL procedure in 3 conditions: without a fixation stimulus (No Fixation – noisiest condition), with a fixation stimulus before trial onset (Fixation, intermediate), and with a fixation stimulus, a neutral background and equally salient images (Fixation Plus – least noisy). Data were systematically analyzed considering a range of data selection criteria and dependent variables (proportion of looking time towards the target, longest look, and time-course analysis). Critically, the expected pronunciation and naming interaction was only found in the Fixation Plus condition. We discuss the impact of data selection criteria and the dependent variable choice on the modulation of these effects across the different conditions.     

A note on structural models for the circumplex

Jöreskog (1974) developed a latent variable model for the covariance structure of the circumplex which, under certain conditions, includes a model for a patterned correlation matrix (Browne, 1977). This model is of limited usefulness, however, in that it employs a known matrix that is rank deficient for many problems. Furthermore, the model is inappropriate for the circumplex which contains negative covariances. This paper presents alternative models for the perfect circumplex and quasi-circumplex that avoids these difficulties, and that includes the important model for a patterned correlation circumplex matrix. Two numerical examples are provided.This research was supported in part by a grant from the Graduate School of the University of Minnesota. I wish to thank M. W. Browne for suggesting the final model presented in this paper. James Steiger and the Editor also made several valuable suggestions.     

Heterogeneous factor analysis models: A bayesian approach

Multilevel factor analysis models are widely used in the social sciences to account for heterogeneity in mean structures. In this paper we extend previous work on multilevel models to account for general forms of heterogeneity in confirmatory factor analysis models. We specify various models of mean and covariance heterogeneity in confirmatory factor analysis and develop Markov Chain Monte Carlo (MCMC) procedures to perform Bayesian inference, model checking, and model comparison.We test our methodology using synthetic data and data from a consumption emotion study. The results from synthetic data show that our Bayesian model perform well in recovering the true parameters and selecting the appropriate model. More importantly, the results clearly illustrate the consequences of ignoring heterogeneity. Specifically, we find that ignoring heterogeneity can lead to sign reversals of the factor covariances, inflation of factor variances and underappreciation of uncertainty in parameter estimates. The results from the emotion study show that subjects vary both in means and covariances. Thus traditional psychometric methods cannot fully capture the heterogeneity in our data.     

理解方法论视野中的读者与文本——加达默尔与方法论诠释学

Judging Gadamer’s theoretical stance is a complicated matter, and his ontological hermeneutics is usually regarded as a text-centered theory of understanding. Through an analysis of the phenomenological premises from which his theories take off, however, we can clearly see his reader-centric stance. On the basis of this stance some cease to seek for the original intention of the author or the original meaning of the text, which ineluctably leads to the ignorance of an understanding methodology. As far as people’s intentional understanding is concerned, however, the important as well as essential task is still that of striving for a certain kind of understanding that is relatively correct, with universally effective methodology as its necessary prerequisite. What is more, herein lies the significance of the epistemology of hermeneutics. This article aims to re-insert a sense of methodology after hermeneutics went through a period of ontological reflection, and hence clarify that it is of necessity that hermeneutics resumes its text-centric methodological stance. __________ Translated by Zhang Lin from Zhongguo shehui kexue 中国社会科学 (Social Sciences in China), 2008, (2): 42–53     

Post‐traumatic functional recovery and reorganization in animal models: A theoretical and methodological challenge

Studies addressing cerebral functional localization face methodological and theoretical problems. Lesion experiments expect that when a functionally specialized structure is missing, its function can be deduced from the resulting impairments. Mostly, however, initial impairments are partially or fully eliminated through functional recovery. Apparently, such a recovery contradicts the notion of functional localization. In order to understand the mechanisms of recovery, improved methodology and a new theoretical framework are required. Insights into the mechanisms of recovery can be achieved by using “challenge” techniques, where functionally recovered individuals are exposed to organic and behavioral challenges, e.g. pharmacological manipulations or additional lesions, as well as modified test situations. Using such methods, a number of principles of functional recovery have emerged. We evaluate some of the available theories of post‐traumatic recovery against these principles and find that none of them can account for the principles. Finally, we present a new conceptual framework – the Reorganization of Elementary Functions (REF) model. This model reconceptualizes the term “function”, suggests mechanisms of post‐traumatic reorganizations, and resolves the contradiction between localization and functional recovery.     

A note on monotonicity of item response functions for ordered polytomous item response theory models

A monotone relationship between a true score (τ) and a latent trait level (θ) has been a key assumption for many psychometric applications. The monotonicity property in dichotomous response models is evident as a result of a transformation via a test characteristic curve. Monotonicity in polytomous models, in contrast, is not immediately obvious because item response functions are determined by a set of response category curves, which are conceivably non-monotonic in θ. The purpose of the present note is to demonstrate strict monotonicity in ordered polytomous item response models. Five models that are widely used in operational assessments are considered for proof: the generalized partial credit model (Muraki, 1992, Applied Psychological Measurement, 16, 159), the nominal model (Bock, 1972, Psychometrika, 37, 29), the partial credit model (Masters, 1982, Psychometrika, 47, 147), the rating scale model (Andrich, 1978, Psychometrika, 43, 561), and the graded response model (Samejima, 1972, A general model for free-response data (Psychometric Monograph no. 18). Psychometric Society, Richmond). The study asserts that the item response functions in these models strictly increase in θ and thus there exists strict monotonicity between τ and θ under certain specified conditions. This conclusion validates the practice of customarily using τ in place of θ in applied settings and provides theoretical grounds for one-to-one transformations between the two scales.     

Single-process versus multiple-strategy models of decision making: Evidence from an information intrusion paradigm

When decision makers are confronted with different problems and situations, do they use a uniform mechanism as assumed by single-process models (SPMs) or do they choose adaptively from a set of available decision strategies as multiple-strategy models (MSMs) imply? Both frameworks of decision making have gathered a lot of support, but only rarely have they been contrasted with each other. Employing an information intrusion paradigm for multi-attribute decisions from givens, SPM and MSM predictions on information search, decision outcomes, attention, and confidence judgments were derived and tested against each other in two experiments. The results consistently support the SPM view: Participants seemingly using a “take-the-best” (TTB) strategy do not ignore TTB-irrelevant information as MSMs would predict, but adapt the amount of information searched, choose alternative choice options, and show varying confidence judgments contingent on the quality of the “irrelevant” information. The uniformity of these findings underlines the adequacy of the novel information intrusion paradigm and comprehensively promotes the notion of a uniform decision making mechanism as assumed by single-process models.     

Lay theories and intergroup relations: A social-developmental perspective

Abundant research suggests that the study of lay theories helps to explain intergroup relations. Building on this work as well as “interactionist” theories for understanding social behaviour from developmental and social psychology, we propose an integrative social-developmental perspective examining how lay perceivers' characteristics (e.g., age, race, psychological motivations) interact with the environments in which they are nested to impact lay theory use over time and during life transitions. Using this perspective to guide our investigation of the Protestant work ethic (PWE) and colourblind theory, we show that a single lay theory can have a socially tolerant or intolerant meaning. We review work with US children and adults (Asians, Blacks, Latinos, Whites) as well as research with Colombian children and adults (Mestizos), showing similarities and differences in perceivers' uses of PWE and the colourblind theory. Even when both meanings are prevalent in a given culture, they are not necessarily equally emphasised in all environments or for all people living in those environments, nor are they responded to in the same way by all people. We discuss the implications of these results for theorising on lay theories and offer directions for future work in this area.     

Social network analysis: A methodological introduction

Social network analysis is a large and growing body of research on the measurement and analysis of relational structure. Here, we review the fundamental concepts of network analysis, as well as a range of methods currently used in the field. Issues pertaining to data collection, analysis of single networks, network comparison, and analysis of individual-level covariates are discussed, and a number of suggestions are made for avoiding common pitfalls in the application of network methods to substantive questions.     

A broad assessment of theory of mind in adolescence: The complexity of mindreading

The aim of this research was to provide an articulated assessment of several different ToM components, namely first- vs. third-person, egocentric vs. allocentric, and first- vs. second-order ToM, in preadolescence and adolescence. Our expectations for the sample of 80 juveniles that participated in the research were that: (1) ToM abilities would improve with age; (2) participants would perform better at first-person than at third-person tasks; (3) participants would perform better at first-order than at second-order tasks; (4) girls will perform systematically better than boys. We also explored possible differences in performance (5) in the allocentric vs. the egocentric perspectives as well as (6) in the comprehension of different types of mental states, namely desires, beliefs and positive and negative emotions. Overall our expectations were confirmed. Our data confirmed that all ToM aspects we investigated keep maturing during preadolescence and adolescence.     

A note on identification in the oblique and orthogonal factor analysis models

Conditions for removing the indeterminancy due to rotation are given for both the oblique and orthogonal factor analysis models. The conditions indicate why published counterexamples to conditions discussed by Jöreskog are not identifiable.The author would like to thank Gordon Bechtel and the reviewers for their comments and suggestions.     

Interpersonal attraction and person perception: Two tests of three balance models

Two experiments tested the adequacy of three balance models (equal-weights tetrahedron model, unequal-weights tetrahedron model, Feather model) for the p?o?x triad. In the first experiment, involving a variation of Byrne's anonymous-stranger technique, a PDP-11 computer was used to provide feedback on five attitude issues for each of the cells of a design created by five levels of the p?x variable (?2, ?1, 0, +1, +2) and five levels of the o?x variable (?2, ?1, 0, +1, +2). The dependent variable was p?o, interpersonal attraction. In the second experiment there were five-level manipulations of both p?x and o?p with an o-x (person perception) dependent variable. The correlations between obtained results and the predicted values for each of the three models were quite high (.64, .65, .61, respectively, in the first experiment and .60, .59, and .58, respectively, in the second), but the Feather model was judged least adequate. The data in the first experiment were best described by the unequal-weights tetrahedron model, and the data in the second experiment were best described by the equal-weights tetrahedron model. It was argued that avoidance of mutual dislike was responsible for the relatively greater support for the unequal-weights than equal-weights tetrahedron model in the first experiment.     

Dyadic longitudinal models: A critical review

In this review, we discuss the most commonly used models to analyze dyadic longitudinal data. We start the review with a definition of dyadic longitudinal data that allows relationship researchers to identify when these models might be appropriate. Then, we go on to describe the three major models commonly used when one has dyadic longitudinal data: the dyadic growth curve model (DGCM), the actor–partner interdependence model (APIM), and the common fate growth model (CFGM). We discuss when each model might be used and strengths and weaknesses of each model. We end with additional thoughts that focus on extensions to new methods being discussed in the literature, along with some of the challenges of collecting and analyzing dyadic longitudinal data that might be helpful for future dyadic researchers.
