Validating Measures of Psychological Well-being by Contrasting Samples Employed in Hazardous and Less Hazardous Work

The study investigated whether differences between contrasting groups reflect significant differences in psychological well-being scores. Membership of hazardous vs. less hazardous occupations in the same profession served as proxy measures of well-being. Antonovsky's Sense of Coherence (SOC), Block & Kremen's Ego-resiliency, and Goldberg's Emotional Stability scales were validated. Study 1 compared mine rescue team members and ordinary miners (n = 34, 41) and Study 2 police special task force members and regular officers (n = 43, 41). In Study 1, SOC and job satisfaction predicted group membership. In Study 2, satisfaction with life and extraversion scales predicted group membership, as did SOC in a secondary analysis. The SOC scale could predict psychological well-being in hazardous work settings.     

Frequent Versus Non-frequent Prompts and Task Performance in Persons with Severe Intellectual Disability

Abstract

This study extended the evaluation of frequent vs non-frequent prompts to support task performance with people with severe intellectual disability. Three participants were involved in the study. The data indicated that the frequent prompts strategy promoted higher levels of on-task behaviour and correct responding for 2 participants and on-task behaviour for 1 participant. The relation of these data with previous findings and their implications for daily occupation programmes for persons with severe developmental disabilities are discussed     

Thought listing and endorsement measures of self-referential thinking in test anxiety

Abstract

The primary purpose of the present study was to examine cognitive reactions of high and low test-anxious subjects while performing a task of extreme difficulty. A sample of 44 subjects (28 females, 16 males) attempted a difficult analogies task and then reported their thoughts during the task. Subjects also completed the Sarason Test Anxiety Scale and several other self-report measures of their cognitive reactions to the task. Thought listings were classified according to their referent (self, task, or unrelated) and their valence (positive, negative, or neutral). Correlational analyses were then performed with the various measures and revealed an association between test anxiety and reports of negative thoughts involving the self. Test anxiety was not related significantly to the number of thoughts involving the task nor to actual performance on the task. However, test-anxious subjects did report more negative expectancies for their performance and greater cognitive interference during the task. Negative self-expectancies were also related to more negative self thoughts, fewer positive self thoughts, and fewer positive task-related thoughts. The results are interpreted as further evidence for both the role of negative self-related cognitions in the experience of test anxiety and the usefulness of unstructured measures in anxiety research.     

History and Analysis of Delayed Discovery Statutes of Limitations in Adult Survivor Litigation

Summary

In this chapter, attorney Mary R. Williams examines how while Childhood Sexual Abuse (CSA) cases share many of the types of facts for which delayed discovery, mental incapacity, equitable estoppel and other legal statutes of limitations doctrines were created, the combination of factors of CSA cases, including unusual social dynamics and long-term psychological effects, does not fit exactly with any of these legal doctrines. She explores the historical development of delayed discovery statutes of limitations, evaluates the different types of statutes and case law, and analyzes the problematic use of the concept of repression in legislation. This chapter interprets her ground-breaking state-by-state tabulations of delayed discovery statutes of limitations and reported appellate decisions on limitations in CSA actions, published in this volume as appendices A, B, and C.     

Holistic processing in the composite task depends on face size

Holistic processing is a hallmark of face processing. There is evidence that holistic processing is strongest for faces at identification distance 2–10 metres from the observer. However, this evidence is based on tasks that have been little used in the literature and that are indirect measures of holistic processing. We use the composite task—a well validated and frequently used paradigm—to measure the effect of viewing distance on holistic processing. In line with previous work, we find a congruency x alignment effect that is strongest for faces that are close (2 m equivalent distance) than for faces that are further away (24 m equivalent distance). In contrast, the alignment effect for same trials, used by several authors to measure holistic processing, produced results that are difficult to interpret. We conclude that our results converge with previous findings providing more direct evidence for an effect of size on holistic processing.     

Structural equation modelling of human judgement

Structural equation modelling (SEM) is outlined and compared with two non-linear alternatives, artificial neural networks and “fast and frugal” models. One particular non-linear decision-making situation is discussed, that exemplified by a lexicographic semi-order. We illustrate the use of SEM on a dataset derived from 539 volunteers' responses to questions about food-related risks. Our conclusion is that SEM is a useful member of the armoury of techniques available to the student of human judgement: it subsumes several multivariate statistical techniques and permits their flexible combination, and it provides robust goodness-of-fit statistics and is available in (generally) easy-to-use computer packages. Although the number of tasks for which SEM provides a persuasive psychological model is small, it is very useful in identifying the important variables and their inter-relations that contribute to task performance, and thus can constitute a valuable intermediate staging point between raw data and a fully fledged psychological theory.     

Exploring the determinants of dual goal facilitation in a rule discovery task

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing.     

Dissimilar effects of task‐relevant and interpersonal threat on independent–interdependent self‐construal in individuals with high self‐esteem

Previous research has indicated that individuals with high trait self‐esteem (HSEs) become more independent and less interdependent after experiencing a task‐relevant threat. However, these studies have not investigated other sources of ego threats, such as interpersonal threats. Therefore, the moderating effects of the degree of trait self‐esteem on task‐relevant and interpersonal ego threats were investigated in relation to independent, or interdependent self‐construal. It was predicted that in HSEs, the level of task‐relevant stress would be positively–negatively related to their independence–interdependence, whereas the level of interpersonal stress would be negatively–positively related to their independence–interdependence. In individuals with low trait self‐esteem (LSEs), the two types of stresses and independent–interdependent self‐construal may not have a significant relationship. We conducted a questionnaire survey with undergraduates. Correlational analysis of the results indicated that in HSEs, greater task‐relevant stress was related to heightened independence, whereas greater interpersonal stress had the opposite effect, indicating lower independence and heightened interdependence. However, these stresses were not related to the self‐construal of LSEs. These findings suggest that task‐relevant and interpersonal threat could have differential effects on independent and interdependent self‐construal for HSEs, but not in LSEs.     

Hemispheric lateralization in aging: Interest of the verbal-manual concurrency paradigm

ABSTRACT

Introduction: The aim of this study was to evaluate whether the classic asymmetry seen in hemispheric functioning is modified in older adults by using a verbal-manual concurrency task. Method: Thirty-five right-handed participants divided into two groups according to age (15 older participants, mean age: 68 ± 8 years, without cognitive decline and 20 younger participants, mean age: 23 ± 2 years) had to perform a 30-second uni-manual tapping task, in both a single task (tapping alone) and dual task (tapping and performing a letter fluency task together) condition. Results: In younger participants, the letter fluency task disrupted the right hand more than the left hand whereas, in older participants, the letter fluency task disrupted both hands equally. Conclusion: These results should be considered preliminary data using a behavioral dual task condition, which might be useful for studying lateralized hemispheric functioning and the processes of divided attention during aging.     

Location- and object-based inhibition of return are affected by different kinds of working memory

Castel, Pratt, and Craik (2003) have shown that inhibition of return (IOR, the delayed response to a recently cued item) is disrupted by a secondary task that involves spatial working memory (WM), and they suggest that IOR is mediated by spatial WM. However, they did not specify what kind of IOR was involved. We used a dual-task paradigm to examine whether the two kinds of IOR (location- and object-based IOR) are affected by two kinds of secondary task that involve spatial and nonspatial WM, respectively. The results show that location-based IOR was disrupted by a spatial secondary task while the object-based IOR was disrupted by a nonspatial secondary task. The present study further elaborates the conclusion of Castel et al. (2003) by differentiating the effect of the two kinds of WM (spatial vs. nonspatial) on the two kinds of IOR (location based vs. object based).
