External Correlates of the Personality Assessment Inventory Higher Order Structures

This brief report explores the external correlates of 2 higher order structures of the Personality Assessment Inventory (PAI; Morey, 1991, 2007); Hoelzle and Meyer's (2009a, 2009b) PAI Components and Hopwood and Moser's (2011) Internalizing and Externalizing Dimensions. Scores from these higher order structures were correlated with life-event data including education, marital status, employment, suicide attempts, psychiatric hospitalizations, trauma, medical problems, hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrest. Although some differences were noted, the results showed that both Hoelzle and Meyer's Components and Hopwood and Moser's Dimensions were meaningfully correlated with a wide range of life outcomes in a conceptually consistent manner. Overall, these findings provide support for the utility of these higher order variables.     

Comparing learned predictiveness effects within and across compound discriminations

In four human learning experiments, we examined the extent to which learned predictiveness depends upon direct comparison between relatively good and poor predictors. Participants initially solved (a) linear compound discriminations in which one or both of the stimuli in each compound were predictive of the correct outcome, (b) biconditional discriminations where only the configurations of the stimuli were predictive of the correct outcome, or (c) pseudodiscriminations in which no stimulus features were predictive. In each experiment, subsequent learning and test stages were used to assay changes in the associability of each stimulus brought about by its role in the initial discriminations. Although learned predictiveness effects were observed in all experiments (i.e., previously predictive cues were more readily associated with a new outcome than previously nonpredictive cues), the same changes in associability were observed regardless of whether the stimulus was initially learned about in the presence of an equally predictive, more predictive, or less predictive stimulus. The results suggest that learned associability is not controlled by competitive allocation of attention, but rather by the absolute predictiveness of each individual cue.     

The acquisition of conditioned responding

This report analyzes the acquisition of conditioned responses in rats trained in a magazine approach paradigm. Following the suggestion by Gallistel, Fairhurst, and Balsam (2004), Weibull functions were fitted to the trial-by-trial response rates of individual rats. These showed that the emergence of responding was often delayed, after which the response rate would increase relatively gradually across trials. The fit of the Weibull function to the behavioral data of each rat was equaled by that of a cumulative exponential function incorporating a response threshold. Thus, the growth in conditioning strength on each trial can be modeled by the derivative of the exponential--a difference term of the form used in many models of associative learning (e.g., Rescorla & Wagner, 1972). Further analyses, comparing the acquisition of responding with a continuously reinforced stimulus (CRf) and a partially reinforced stimulus (PRf), provided further evidence in support of the difference term. In conclusion, the results are consistent with conventional models that describe learning as the growth of associative strength, incremented on each trial by an error-correction process.     

The X-claim argument against religious belief offers nothing new

Stephen Law has recently offered an argument against the rationality of certain religious beliefs that he calls the X-claim argument against religious beliefs (Law in Relig Stud, 2017,  https://doi.org/10.1017/s0034412526000330). The argument purports to show that it is irrational to believe in the existence of extraordinary beings associated with religions. However, the X-claim argument is beset by certain ambiguities that, once resolved, leave the argument undifferentiated from two other common objections to the rationality of religious belief: the objection from religious diversity and the objection from unreliable sources. And though the latter pose serious obstacles to the rationality of religious belief, the X-claim argument adds no further difficulty.     

Maximizing Scales Do Not Reliably Predict Maximizing Behavior in Decisions from Experience

In this paper, we explore the relationships between psychometric and behavioral measures of maximization in decisions from experience (DfE). In two experiments, we measured choice behavior in two experimental paradigms of DfE and self‐reported maximizing tendencies using three prominent scales of maximization. In the repeated consequentialist choice paradigm, participants made repeated choices between two unlabeled options and received consequential feedback on each trial. In the sampling paradigm, participants freely sampled from two options and received feedback on their sampling before making a single consequential choice. Individuals exhibited different degrees of maximizing behavior in both paradigms and across different payoff distributions, but none of the maximizing scales predicted this behavior. These results indicate that maximization scales address constructs that are different from the maximization behavior observed in DfE, and that these measures will need to be improved to reflect behavioral aspects of choice and search from experience.

Developing an instrument to measure physical activity related self-worth in women: Rasch analysis of the Women's Physical Activity Self-Worth Inventory (WPASWI)

ObjectivesThe objective of this study is to report on the development of an instrument to assess non-physical aspects of physical activity (PA)-related self-worth (SW).MethodsThree hundred thirty five women (mean age = 36.69 ± 15.94 yrs, BMI = 24.87 ± 4.56) completed the Women's Physical Activity Self-Worth Inventory (WPASWI), General SW Scale, and a PA Questionnaire. Rasch analysis was used to evaluate the WPASWI.ResultsThree PA-related SW subscales were identified: PA Knowledge (16 items), PA Emotional (13 items), and PA Social (8 items). Rasch analysis supported construct validity, and items demonstrated acceptable internal consistency (Cronbach's alpha = 0.90, 0.87 and 0.72) and test-re-test reliability (r = 0.79, 0.70, 0.81). Women who reported regular PA participation had higher PA Knowledge, PA Emotional, PA Social, and General SW than those who reported some or no PA (p < 0.01) and correlations between Knowledge, Emotional, and Social SW subscales and General SW were 0.207, 0.130, and 0.220, respectively. PA Knowledge and PA Emotional SW had stronger correlations with PA (r = 0.344, 0.273, respectively) than did General SW (r = 0.133).ConclusionsThe WPASWI demonstrated good internal consistency, reliability, construct validity and a stronger relationship with PA than a General SW instrument.     

Emotionally-focused therapy and treatment as usual comparison groups in decreasing depression: A clinical pilot study

Abstract

Decades of research have shown that depression can have deleterious effects on couple relationships. Emotionally-focused therapy (EFT; Johnson, 2004 Johnson, S. M. (2004). The practice of emotionally focused couple therapy: Creating connection. East Sussex, UK: Brunner-Routledge. [Google Scholar]) is an empirically validated form of couple therapy, which has shown effectiveness in reducing depressive symptoms in couples where the wife has depression. The aim of the current pilot study was to examine the extent to which EFT and the comparison treatment as usual (TAU) therapy group decrease depressive symptoms in distressed couples. Results show that both groups were effective in decreasing depressive symptoms, with EFT showing a clinically significant reduction. Clinical implications and future research are discussed.     

Expectancy bias mediates the link between social anxiety and memory bias for social evaluation

Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.
