Fit to forgive: Exploring the interaction between regulatory focus, repentance, and forgiveness.

Three studies, using diverse methodologies and measures, were conducted to examine the role that the regulatory focus of an injured party and of a transgressor (E. T. Higgins, 1997, 2000) plays in explaining the relationship between repentance and forgiveness. The authors predicted that when a victim's regulatory focus (i.e., promotion vs. prevention) was congruent (i.e., fit) with the regulatory focus of a transgressor's repentance (i.e., promotion vs. prevention), there would be greater forgiveness compared with when there was incongruence (i.e., mismatch). Three studies supported these predictions. The results also confirmed one potential explanation for why apologies are not always successful at eliciting forgiveness, namely, feeling right. This research suggests that regulatory focus theory can help inform the scientific study of forgiveness and its related processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

(Why) do I think what you think? Epistemic social tuning and implicit prejudice.

This research examines whether people who experience epistemic motivation (i.e., a desire to acquire knowledge) came to have implicit attitudes consistent with the apparent beliefs of another person. People had lower implicit prejudice when they experienced epistemic motivation and interacted with a person who ostensibly held egalitarian beliefs (Experiments 1 and 2). Implicit prejudice was not affected when people did not experience epistemic motivation. Further evidence shows that this tuning of implicit attitudes occurs when beliefs are endorsed by another person, but not when they are brought to mind via means that do not imply that person's endorsement (Experiment 3). Results suggest that implicit attitudes of epistemically motivated people tune to the apparent beliefs of others to achieve shared reality.

Implementing Observational Research Methods to Study Team Performance in Construction Management

The evolution of research in the area of construction engineering and management has moved toward the use of quantitative metrics and research methods for identifying and evaluating the impact of events or procedures on the construction process. While quantitative research methods can be very important for answering certain research questions, there are important reasons for adopting qualitative or mixed methodology studies to gain a better understanding of complex phenomena. This paper explores the use of observational studies and their potential use within the field of construction research. Observational studies can provide answers to “what” phenomena occurred, particularly when people are involved in a process, along with gaining insights into “why” the phenomena occurred. This paper discusses two types of observational studies, structured and unstructured, and provides a procedure for their implementation within construction research. To clearly demonstrate the methodology, a case study focused on the investigation of two different versions of an educational simulation application, the virtual construction simulator (VCS), is used to illustrate the benefits and challenges of implementing mixed methodology observational studies. The case study involved the video recording and analysis of interactions between student team members when using the VCS application for a construction sequencing task. The video recordings were analyzed, and important insights were identified, both qualitative and quantitative. Through content analysis, it was determined that the improvements made in a new version of the VCS application were beneficial, and the detailed observational studies identified insights into why the revisions in the application yielded improved results. This case study details the steps and considerations involved in planning an observational study, as well as the benefits and challenges that researchers may encounter when using observational research methodologies.     

I think we can.

Case studies and self-experiments have been and continue to be a part of the professional literature in psychology. Whether practicing knowledge is the same type of knowledge needed to validate the efficacy of practice is the question. The generalization of self-report methodologies to acceptance of case studies or self-experiments as primary tools of scientific validation cannot be made.

Conceptual versus experimental creativity: Which works best on convergent and divergent thinking tasks?

David Galenson's research on creativity has identified two unique creative methods: conceptual and experimental. These methods have different processes, goals, and purposes. To determine whether (a) college students use one method more than the other, and (b) if one method is superior to the other, the authors randomly assigned 115 college students to use the conceptual creative method, the experimental creative method, or their own creative method (i.e., how they would solve a creative problem without instruction) while completing two types of convergent and divergent thinking tasks. Participants using the experimental creative method performed better than the other groups on both types of convergent thinking tasks, with most participants using the experimental creative method unaware of this increase in performance.

"Who am I? Why am I here?" Self-esteem, self-clarity, and prototype matching.

Recent research has demonstrated that individuals with low self-esteem lack self-clarity; they have less certain and less stable self-concepts than do those with high self-esteem (A. H. Baumgardner; see PA, Vol 77:30941; J. Campbell; see PA, Vol 78:4413). Self-concept confusion should mitigate against the use of a decision-making strategy that involves using the self to guide choice behavior (i.e., prototype matching; P. M. Niedenthal et al; see record 1985-20122-001). Two correlational studies demonstrated that people with high self-esteem, but not low self-esteem, made use of prototype matching in forming preferences. In a 3rd study, the self-concept was made more clear or made more confused. Clarity was associated with the use of prototype matching regardless of level of self-esteem. Self-concept confusion was associated with a failure to use the strategy regardless of level of self-esteem. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Projections of aging: Impact of generational differences and the aging process on perceptions of adults.

In the domain of personality, a variety of stereotypes about old age are found. Unfortunately, the methodologies of previous studies have not dealt with a potential confound as to whether attitudes are a function of the aging process or of perceptions of generations. The present study was designed as a first step toward distinguishing between these possibilities. Young adults rated one target generation (i.e., today's 22-, 41-, or 69-year-olds) at one age period (i.e., as 22-, 41-, or 69-year-olds) on a series of personality attributes. Results demonstrated that attitudes (i.e., perceptions of personality) varied more often as a function of target generation, reflecting a general tendency for young adults to view other generations in a different fashion from the way they view their own. Overall, attitudes toward the older generation or age period were more positive than negative. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Therapists’ views on working with bilingual Spanish–English speaking clients: A qualitative investigation.

Through semistructured interviews, language switching in therapy was examined with 9 bilingual Spanish and English therapists. Therapists were asked about how and when they switched from one language to another during treatment, as well as the ways in which their clients’ switched languages. After the use of consensual qualitative research methods (C. E. Hill et al., 2005; C. E. Hill, B. J. Thompson, & E. N. Williams, 1997), the results revealed that therapists used language switching as a mechanism to establish trust, bond with clients, and promote disclosure through the use of specific phrases or specific words; particularly, the use of Spanish idiomatic expressions (dichos) served to engage, redirect, and increase client self-understanding and awareness. Therapists reported that their clients switched from English to Spanish when recounting experiences that involved certain emotions (e.g., anger) and represented themselves differently depending on the language they were speaking. Therapists also reported that their clients switched from English to Spanish to improve communication and to connect with them. Future directions for research and implications for training and practice are outlined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Using analysis of covariance (ANCOVA) with fallible covariates.

Analysis of covariance (ANCOVA) is used widely in psychological research implementing nonexperimental designs. However, when covariates are fallible (i.e., measured with error), which is the norm, researchers must choose from among 3 inadequate courses of action: (a) know that the assumption that covariates are perfectly reliable is violated but use ANCOVA anyway (and, most likely, report misleading results); (b) attempt to employ 1 of several measurement error models with the understanding that no research has examined their relative performance and with the added practical difficulty that several of these models are not available in commonly used statistical software; or (c) not use ANCOVA at all. First, we discuss analytic evidence to explain why using ANCOVA with fallible covariates produces bias and a systematic inflation of Type I error rates that may lead to the incorrect conclusion that treatment effects exist. Second, to provide a solution for this problem, we conduct 2 Monte Carlo studies to compare 4 existing approaches for adjusting treatment effects in the presence of covariate measurement error: errors-in-variables (EIV; Warren, White, & Fuller, 1974), Lord's (1960) method, Raaijmakers and Pieters's (1987) method (R&P), and structural equation modeling methods proposed by S?rbom (1978) and Hayduk (1996). Results show that EIV models are superior in terms of parameter accuracy, statistical power, and keeping Type I error close to the nominal value. Finally, we offer a program written in R that performs all needed computations for implementing EIV models so that ANCOVA can be used to obtain accurate results even when covariates are measured with error.

Confirmatory analysis of opinions regarding the pros and cons of mammography.

This investigation extends prior research to apply decision-making constructs from the transtheoretical model (TTM) of behavior change to mammography screening. Study subjects were 8,914 women ages 50–80, recruited from 40 primarily rural communities in Washington State. Structural equation modeling showed that favorable and unfavorable opinions about mammography (i.e., pros and cons) fit the observed data. Analysis of variance supported the associations between readiness to obtain screening (i.e., stage of adoption) and opinions about mammography (i.e., decisional balance) previously found in research using smaller samples from another geographic region. This report extends these earlier studies by using structural equation modeling, opinion scales based both on principal component analyses and on a priori definitions, a developmental sample and a confirmatory sample, and by sampling from a different geographic region. It is recommended that future research examine whether opinions regarding the cons of mammography are more individually specific than the pros.

Treatment Utility of Psychological Assessment.

This article focuses on treatment utility. A definition of treatment utility was provided by S. C. Hayes, R. O. Nelson, and R. B. Jarrett (1987): "We propose to use the phrase the treatment utility of assessment to refer to the degree to which assessment is shown to contribute to beneficial treatment outcome" (p. 963). Various methodologies to examine the treatment utility of assessment are summarized. Treatment utility studies using various assessment procedures (i.e., diagnosis and functional analysis) and various disorders (i.e., unipolar depression, social or interpersonal problems, and phobic disorders) are described. Suggestions are made as to when elaborated assessment and/or treatment utility studies are needed. Limitations on the generalizability of results of any particular treatment utility study are presented. Despite progress, for most assessment procedures and devices, the treatment utility question remains: What is the degree to which assessment is shown to contribute to beneficial treatment outcome?

Reinforcing effects of stimulants in humans: Sensitivity of progressive-ratio schedules.

Drug self-administration methodologies have been developed for use in humans to model naturalistic stimulant drug-taking behaviors. These methodologies use a number of schedules of reinforcement, including progressive-ratio schedules. As the name implies, in a progressive-ratio schedule, the response requirement for each subsequent delivery of drug increases, and the primary outcome variable is often the break point (i.e., the last ratio completed to receive a drug delivery). These schedules have been used in a number of human laboratory studies evaluating the reinforcing effects of stimulants. The results of these studies have demonstrated that progressive-ratio schedules are sensitive to manipulation of a pharmacological variable, dose, and to nonpharmacological variables contributing to stimulant drug effects. In addition, findings with progressive-ratio schedules are largely concordant with clinical findings, suggesting that drug self-administration under these schedules has predictive validity in terms of drug abuse and dependence. Future research is necessary, however, to understand better how pharmacological factors like route of administration, onset of effects, and pretreatment influence the reinforcing effects of stimulants under progressive-ratio schedules.

Understanding metaphorical comparisons: Beyond similarity.

Traditionally, metaphors such as "my job is a jail" have been treated as implicit similes (i.e., this metaphor would be treated as if it were a comparison statement, "my job is like a jail"). A. Tversky's (1977) account of similarity is applied to such nonliteral similarity expressions, and is shown to apply as readily to nonliteral comparisons as to literal comparisons. But treating metaphors as comparison statements fails to account for certain important phenomena, including metaphoricity itself (the judgment that a comparison statement is nonliteral). We argue that metaphors are exactly what they appear to be: class-inclusion assertions, in which the topic of the metaphor (e.g., "my job") is assigned to a diagnostic category (e.g., entities that confine one against one's will, are unpleasant, are difficult to escape from). In such assertions, the metaphor vehicle (e.g., "jail") refers to that category, and at the same time is a prototypical exemplar of that category. This account of metaphor provides a basis for a theory of metaphor comprehension, and also clarifies why people use metaphors instead of similes.

Bias in meta-analytic estimates of the absolute efficacy of psychotherapy.

Meta-analytic estimates of the absolute efficacy of psychotherapy indicate an effect size of approximately 0.80. However, various biases in primary and meta-analytic studies may have influenced this estimate. This study examines 4 nonsystematic biases that increase error variance (i.e., nonrandomized designs, methodological deficiencies, failure to use the study as the unit of analysis, and violations of homogeneity), 4 underestimation biases that primarily concern psychometric issues (i.e., unreliability of outcome measures, failure to report nonsignificant effect sizes, nonoptimal composite outcome measures, and nonstandardized outcome measures), and 8 overestimation biases (i.e., excluding nonsignificant effects from calculations of effect size estimates, failure to adjust for small sample bias, failure to separate studies using single-group pre-post designs vs. control group designs, using unweighted average effect sizes, analyzing biased partial samples that reflect treatment dropout and research attrition, researcher allegiance bias, publication bias, and wait-list control group bias). Wherever possible, evidence regarding the magnitude of these biases is presented, and methods for addressing these biases separately and collectively are discussed. Implications of the meta-analytic evidence on psychotherapy for the effect sizes of other psychological interventions are also considered.

The “other IQ”: Historiometric assessments of intelligence and related constructs.

Running parallel to mainstream research on the psychometric assessment of intelligence is another tradition of research on the historiometric assessment of intelligence and closely affiliated variables. Historiometric assessment is based on four data sources: (a) personality sketches (e.g., Intellectual Brilliance), (b) developmental histories (e.g., IQ), (c) content analyses (e.g., integrative complexity), and (d) expert surveys (e.g., Openness to Experience). The first two represent major lines of intelligence research that involved key figures in the development of corresponding psychometric methods (e.g., Galton, Terman, and Thorndike), whereas the last two constitute independent research paradigms that later intersected with the first two. The literature on U.S. presidents then provides an integrated illustration of the four historiometric approaches and how they converge on the same broad conclusions. Significantly, historiometric investigations on the relation between broadly defined intelligence and adulthood achievement obtain about the same effect size as that found in psychometric research (i.e., rs or βs = .25 ± .10). Because historiometric and psychometric studies have rather distinctive methodological advantages and disadvantages, this consistent outcome provides corroborative support for both sets of empirical findings.

Polyurethane Foam Medium for Biofiltration. I: Characterization

Although biological treatment has been applied successfully to treat waste gases using conventional organic packing media such as compost, there is currently a need for further research on ways to optimize the medium selected. Use of a superior filter-bed medium could overcome or minimize many of the problems encountered in conventional biofilter operation (e.g., medium clogging, difficulty in control of moisture content, and nutrient limitation). In research described herein, polyurethane foam was manufactured and characterized to determine its suitability as a solid support medium for use in gas-phase biofilters. Part I of this paper describes studies conducted to determine the medium's porosity, pore size, head loss characteristics, density, sorption capacity, and chemical resistance. Results are presented that characterize the polyurethane foam medium's properties and suggest how it can be used effectively in treating gas-phase volatile organic compound contaminants. Part II of this paper describes studies conducted to determine the medium's ability to support an active biofilm and to study feasibility of a novel nutrient addition and biomass wasting strategy.     

When do fair procedures not matter? A test of the identity violation effect.

Considerable research has demonstrated that fair procedures help improve reactions to decisions, a phenomenon known as the fair process effect. However, in the present research, the authors identify when and why objectively fair procedures (i.e., receiving voice) may not always improve justice perceptions. Findings from 2 studies (Ns = 108 and 277) yield support for the proposed identity violation effect, which posits that when an outcome violates a central aspect of one's self (i.e., personal and/or social identity), objectively fair procedures do not improve procedural and distributive justice perceptions. Further, consistent with the motivated reasoning hypothesis, the Voice × Identity Violation interaction on justice perceptions was mediated by participants' tendency to find a procedural flaw--namely, to doubt that opinions were considered before making the decision.

Sociocultural factors and the development of disordered eating: A longitudinal analysis of competing hypotheses.

Sociocultural models hypothesize causal paths in the development of eating disorders, yet few longitudinal studies have controlled for temporal stability, leaving open the question as to causality and the directionality of effects. In the present study, the authors tested portions of the socioculturally based dual-pathway model, specifically, the risk factor hypotheses that internalization of the thin ideal predicts body dissatisfaction, that body dissatisfaction predicts depressive affect, and that depressive affect predicts disordered eating. The authors also examined competing hypotheses (e.g., disordered eating predicts depressive affect) as well as the possibility of simultaneous relationships (i.e., variables would be related to one another within a time frame). The 6 models (3 cross-lagged and 3 simultaneous) were evaluated using 236 female freshmen who provided self-report data during their 1st semester in college and 6 months later. While controlling for temporal stability, structural equation modeling revealed that (a) internalization and body image each were related to the other across time; (b) body image was related directionally, but only in the simultaneous context, to depressive affect; and (c) depressive affect and disordered eating were related reciprocally and temporally to one another. Directions for future research and implications for intervention are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Should I stay or should I go? Predicting dating relationship stability from four aspects of commitment.

Many have argued that it is important to examine different aspects of commitment in romantic relationships, but few studies have done so. Using a large, national sample of unmarried adults in relationships (N = 1184), this study examined four aspects of relationship commitment and their associations with relationship adjustment and stability. We examined dedication (i.e., interpersonal commitment) as well as three types of constraint commitment: perceived constraints (e.g., social pressure to stay together or difficulty of termination procedures, measured using Stanley and Markman's [1992] Commitment Inventory), material constraints (e.g., signing a lease, owning a pet), and felt constraint (i.e., feeling trapped). Cross-sectionally, these four facets of commitment were associated in expected directions with relationship adjustment, as well as perceived likelihood of relationship termination and of marriage. Longitudinally, each facet uniquely predicted relationship stability. More dedication, more material and perceived constraints and less felt constraint were uniquely associated with a higher likelihood of staying together over an 8-month period.
