Using the IRAP to explore natural language statements

This study explored a modification to the typical presentation of label and target stimuli on Implicit Relational Assessment Procedure (IRAP) effects. We asked whether combining the labels and targets into a single phrase would influence performances. The key purpose of the study was to determine the feasibility of altering the way in which stimuli are presented within the IRAP, so as to potentially employ more complex natural language-like statements in future research. In the Typical IRAP employed here, labels and targets were presented as separate words, while in the Natural Language IRAP they were combined to form a single statement. The results demonstrated no substantive differences in the effects recorded on both types of IRAP, thus supporting the future use of a Natural Language version

An Investigation into the relationship between the gender binary and occupational discrimination using the implicit relational assessment procedure

The social construction of gender-as-binary plays an important role within many contemporary theories of gender inequality. However, to date, the field of psychology has struggled with the operationalization and assessment of binarist ideologies. The current article proposes a technical framework for the analysis of the gender binary and assesses the suitability of the Implicit Relational Assessment Procedure (IRAP) as a measure of binarist gender beliefs. Forty-seven undergraduate students (26 female; M-age = 23.84) completed two IRAPs assessing the coordination of certain traits exclusively with women and others exclusively with men. Effects found on the IRAP were in the expected direction (i.e., relating men but not women with certain traits and women but not men with other traits). In addition, the traits ascribed to men within the IRAP were evaluated as more hirable by a large majority of participants (83%) on an explicit preference task. The results therefore support the arguments that, first, gender traits do seem to be framed oppositionally in language and, second, this binary may underpin existing gender hierarchies in certain contexts

The implicit relational assessment procedure: emerging reliability and validity data

The Implicit Relational Assessment Procedure (IRAP) is a measure of ‘implicit cognition' developed on the basis of a contemporary behavioural analysis of language and cognition. The IRAP has now been applied to a range of foci over five years of published research. A frequently-cited caveat in publications to date is the need for further research to gauge the reliability and validity of the IRAP as an implicit measure. This review paper will provide a critical synthesis of available evidence for reliability and validity. The review applies a multifaceted test-theory approach to validity, and reliability is assessed through meta-analysis of published data. The discussion critically considers reviewed IRAP evidence with reference to the extant literature on alternative implicit measures, limitations of studies to date, and consideration of broader conceptual issues

Body dissatisfaction revisited : on the importance of implicit beliefs about actual and ideal body image

Body dissatisfaction (i.e., a negative attitude towards one’s own physical appearance) is assumed to originate from a perceived discrepancy between the actual physical appearance (i.e., actual body image) and the desired ideal state of the body (i.e., ideal body image). We assessed implicit beliefs about these two aspects of the body image independently using two Relational Responding Tasks (RRT) in a sample of participants who were either low or high in explicitly reported body dissatisfaction. As hypothesized, differences in body dissatisfaction exerted a differential influence on the two RRT scores. The implicit belief that one is thin was less pronounced in participants who were strongly dissatisfied with their body relative to participants who were more satisfied with their body. The implicit desire to be thin (i.e., thin ideal body image), in contrast, tended to be more pronounced in participants who exhibited a high degree of body dissatisfaction as compared to participants who exhibited a low degree of body dissatisfaction. Hierarchical regression analyses also revealed that the RRT scores were predictive of self-reported body dissatisfaction, even over and above the predictive validity of some (but not all) explicit predictors of body dissatisfaction that were included in the present study. More generally, these findings contribute to the empirical validation of the RRT as a measure of implicit beliefs in the context of body dissatisfaction

The Implicit Relational Assessment Procedure (IRAP) as a measure of spider fear, avoidance and approach

The current study examined the use of the Implicit Relational Assessment Procedure (IRAP) as a measure of spider fear, approach, and avoidance. Participants were drawn from a normative sample of university undergraduates. Experiment 1employed two IRAPs, one targeting spider fear, the other targeting spider approach/avoidance. The Fear of Spiders Questionnaire (FSQ) and a Behavioral Approach Task (BAT) using a spider moult were also employed. Negative response biases for spider fear and avoidance, but not for approach, were recorded. The bias for fear was significantly stronger than for avoidance and approach. Both IRAP's failed to provide evidence for the predicative validity of the IRAP in terms of the BAT. Experiment 2 was a partial replication of Experiment 1 but using a live house spider instead of a moult for the BAT. A similar pattern of results was obtained across the two IRAPs, but one specific trial-type (SpiderApproach) predicted approach responses on the BAT. The research, thus, replicated a previously published study by Nicholson and Barnes-Holmes (2012), thus supporting the predictive validity of the IRAP but at a level of precision not provided in the earlier study. Implications for applied research are considered

A pilot study of the relations within which hearing voices participates : towards a functional distinction between voice hearers and controls

The current research used the Implicit Relational Assessment Procedure (IRAP) as a preliminary step toward bringing a broad, functional approach to understanding psychosis, by focusing on the specific phenomenon of auditory hallucinations of voices and sounds (often referred to as hearing voices). On this path, we created a taxonomy of some critical features of voice hearing based on the existing literature (i.e., perceived normality of voices, appraisals of self and other people hearing voices, and fear of voices) as a focus of our experimental manipulations. It was our hope that our findings would add to the broad literature that has used explicit measures to study these phenomena, and that the use of an 'implicit' measure might assist toward a functional analytic understanding. Three pilot studies were conducted to assess the relations within which hearing voices participates in non-clinical voice hearers (i.e., individuals who hear voices but have no clinical diagnosis or distress) and compared to non-voice hearing control participants. The IRAP effects demonstrated both positive and negative relational responses across the three studies, and these effects varied according to explicit levels of delusional ideation. Furthermore, these IRAP effects also predicted explicit aspects of voice hearing and well-being. The current set of pilot studies demonstrate the utility and precision of the IRAP in this domain, and we propose that this type of experimental analysis may hold potential for future bottom-up functional analyses of voice hearing

Functional relations modulate the responsiveness to affordances despite the impact of conflicting stimulus-response mappings

The study investigated how conflicting stimulus-response mappings influenced affordance processing given a manipulation of the functional relations. Participants performed a task involving consistent-inconsistent stimulus-response mappings: Implicit Relational Assessment Procedure (IRAP). They were instructed to confirm or to deny a relation between words and tool-objects (consistent blocks) or to provide non-conventional responses (inconsistent blocks). The relations between stimuli could functionally match (e.g., Kitchen- Spatula) or not (e.g., Kitchen- Hammer), as well as the spatial relations (e.g., a match or a mismatch between participants' hand response and the tool-object orientation). The results showed faster reaction times (RTs) when functional relations between stimuli matched both in consistent and inconsistent blocks. Differences in RTs and accuracy between consistent and inconsistent blocks were only found when the functional relation between stimuli matched. No modulation of the performance was observed for mismatching functional relations and spatial relations between blocks. These results support the hypothesis that the responsiveness to affordances is strongly modulated by matching functional relations, despite the impact of conflicting stimulus-response mappings

Do Transaction Costs and Risk Preferences Influence Marketing Arrangements in the Illinois Hog Industry?

Risk reduction and transaction costs are often used to explain contracting in the U.S. hog industry with little empirical support. Using a unified conceptual framework that draws from risk behavior and transaction cost theories, in combination with unique survey and accounting data, we demonstrate that risk preferences and asset specificity impact Illinois producers’ use of contracts and spot markets. In particular, producers’ investments in specific hog genetics and human capital are related to selection of long-term marketing contracts over spot markets. Producers who perceive greater levels of price risk and/or are more averse are more (less) likely to use contracts (spot markets). Key words: asset specificity, contracts, hogs, risk attitude, risk behavior, risk perception, transaction costs economic
