Category-length and category-strength effects using images of scenes

Global matching models have provided an important theoretical framework for recognition memory. Key predictions of this class of models are that (1) increasing the number of occurrences in a study list of some items affects the performance on other items (list-strength effect) and that (2) adding new items results in a deterioration of performance on the other items (list-length effect). Experimental confirmation of these predictions has been difficult, and the results have been inconsistent. A review of the existing literature, however, suggests that robust length and strength effects do occur when sufficiently similar hard-to-label items are used. In an effort to investigate this further, we had participants study lists containing one or more members of visual scene categories (bathrooms, beaches, etc.). Experiments 1 and 2 replicated and extended previous findings showing that the study of additional category members decreased accuracy, providing confirmation of the category-length effect. Experiment 3 showed that repeating some category members decreased the accuracy of nonrepeated members, providing evidence for a category-strength effect. Experiment 4 eliminated a potential challenge to these results. Taken together, these findings provide robust support for global matching models of recognition memory. The overall list lengths, the category sizes, and the number of repetitions used demonstrated that scene categories are well-suited to testing the fundamental assumptions of global matching models. These include (A) interference from memories for similar items and contexts, (B) nondestructive interference, and (C) that conjunctive information is made available through a matching operation.     

Integrating Covariates into Social Relations Models: A Plausible Values Approach for Handling Measurement Error in Perceiver and Target Effects

The Social Relations Model (SRM) is a conceptual and analytical approach to examining dyadic behaviors and interpersonal perceptions within groups. In an SRM, the perceiver effect describes a person's tendency to perceive other group members in a certain way, whereas the target effect measures the tendency to be perceived by others in certain ways. In SRM research, it is often of interest to relate these individual SRM effects to covariates. However, the estimated individual SRM effects might not provide a very reliable measure of the true, unobserved SRM effects, resulting in distorted estimates of associations with other variables. This article introduces a plausible values approach that allows users to correct for measurement error when assessing the association of individual SRM effects with other individual difference variables. In the plausible values approach, the latent, true individual SRM effects are treated as missing values and are imputed from an imputation model by applying Bayesian estimation techniques. In a simulation study, the statistical properties of the plausible values approach are compared with two approaches that have been used in previous research. A data example from educational psychology is presented to illustrate how the plausible values approach can be implemented with the software WinBUGS.     

Inventar zur therapeutischen Beziehung (ITB)

A successful psychotherapy requires a good therapeutic relationship. An adequate operationalization by German diagnostic instruments has to be improved. A new instrument for measuring the therapeutic relationship from the patient’s perspective is presented. It is suitable for various therapeutic orientations, integrates current empirical findings in a broad theoretical framework and corrects methodological deficits of the existing German questionnaires. The therapeutic relationship questionnaire (ITB) was developed with a sample of 44 therapists and 519 inpatient, outpatient and day clinic patients. The ITB findings confirm a very good reliability (internal consistency and retesting reliability). There is initial evidence for convergent, divergent and differential validity and for associations with therapy effects. The ITB is an economic instrument that in contrast to other questionnaires measures a general factor which could be replicated in several confirmatory and exploratory factor analyses.     

Distribution of Reported Durations of Behavior in Applied Behavioral Research

Duration is a commonly measured dimension of behavior in behavioral research and clinical practice. An approach to studies of measurement in behavior analysis is to simulate streams of behavior from which samples can be extracted. It is therefore important to establish a typical range and distribution of behavioral durations on which simulated behavioral data should be based. We conducted an analysis of behavioral durations reported in the Journal of Applied Behavior Analysis between 2008 and 2012. The range and distribution of data points across different durations will be presented, as well as an analysis of the reliability of the software used to measure each data point.

On Original Sin

This article sets out a constructive account of original sin that attempts to take seriously the Christian tradition (particularly, the Reformed tradition), and that avoids the serious theological drawback of the doctrine of original guilt. I dub this account the moderate Reformed doctrine of original sin. I also argue that an adequate understanding of original sin must be open‐textured enough to accommodate some version of the story of evolutionary human development. Although I do not offer an account of how original sin is consistent with evolutionary human development, the doctrine set out here is commensurate with several live options on this controversial theological topic, which I take to be a strength, rather than a weakness, of the view.
