Is the truth table task mistaken?

There is ample evidence that in classical truth table task experiments false antecedents are judged as “irrelevant”. Instead of interpreting this in support of a suppositional representation of conditionals, Schroyens (2010a Schroyens, W. 2010a. Mistaking the instance for the rule: A critical analysis of the truth-table evaluation paradigm. Quarterly Journal of Experimental Psychology, 63: 246–259. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2010b Schroyens, W. 2010b. A meta-analytic review of thinking about what is true, possible, and irrelevant in reasoning from or reasoning about conditional propositions. European Journal of Cognitive Psychology, 22: 897–921. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) attributes it to the induction problem: the impossibility of establishing the truth of a universal claim on the basis of a single case. In the first experiment a truth table task with four options is administered and the correlation with intelligence is inspected. It is observed that “undetermined” is chosen in one third of the judgements and “irrelevant” in another third. A positive correlation is revealed between intelligence and the number of “irrelevant” and “undetermined” judgements. The data do not exclude that a part of the “irrelevant” judgements in classical truth table task experiments might be caused by the induction problem. In the second experiment participants are presented with a simplified four-option truth table task and asked for a justification of their judgements. These justifications show the induction problem is not the reason for choosing the “irrelevant” or “undetermined” option, which is supportive for a suppositional representation of conditionals.     

Job demands–resources model in the context of recovery: Testing recovery experiences as mediators

The aim of the present study was to extend the original Job Demands–Resources (JD-R) model by taking into account recovery as an important mediation mechanism between work characteristics and well-being/ill-health. Specifically, we examined whether recovery experiences—strategies promoting recovery—might have a mediating role in the JD-R model among 527 employees from a variety of different jobs. The results showed that psychological detachment fully mediated the effects of job demands on fatigue at work and mastery partially mediated the effects of job resources on work engagement. Altogether, the results suggest that recovery merits consideration as a mediating mechanism in the JD-R model.     

Development and validation of an instrument for assessing job demands arising from accelerated change: The intensification of job demands scale (IDS)

Accelerated societal and organizational changes have placed new pressures on employees. Especially, service employees are exposed to intensified workloads, planning and decision-making, and learning demands. Despite the growing attention given to this intensification of job demands, a comprehensive measure is missing. In the present study, we developed the Intensification of Job Demands Scale (IDS) and validated it in four samples (N = 1363). Confirmatory factor analyses supported the differentiation into five subscales, namely work intensification, intensified job-related planning and decision-making demands, intensified career-related planning and decision-making demands, intensified knowledge-related learning demands, and intensified skill-related learning demands. This five-factor structure holds for both the German and the English versions of the instrument. Convergent and discriminant validity tests showed that the IDS subscales are moderately related to established measures of job demands, but at most have small correlations with negative affectivity. Providing support for the incremental validity, the IDS subscales were found to add to the prediction of burnout and job satisfaction beyond established job demands. Finally, the IDS subscales helped to identify employees who experienced changes in their work situation. In sum, the results indicate that the IDS is a valid and reliable measure to assess the intensification of job demands.     

New Concepts for a New Age: Information Service Organizations and Mental Information Work

Abstract

To describe and conceptualize new forms of work and organization a questionnaire survey in service organizations (n = 845), and a telephone survey among workers (n = 1168) were held. New concepts are introduced to identify the types of work and organization found, i.e. “Information Service Organization” (ISO) and “Mental Information Work” (MIW). ISOs are characterized by activities such as collecting, storing, and processing data; advising people; and informing people. They also make a lot of use of IT (computers, programs) and electronic network connections. Most ISOs appear to be traditional in terms of working hours and places of work. MIW is a form of knowledge work characterized by mental manipulations of information; IT is often used. Flexi-time is relatively frequent in MIW, but most people work on a fixed place of work.     

Does an intrinsic work value orientation strengthen the impact of job resources? A perspective from the Job Demands–Resources Model

Based on assumptions of the Job Demands–Resources model and the Person–Environment fit literature, the present research conceptualizes an intrinsic relative to an extrinsic work value orientation as a personal resource. We examine whether such an orientation may strengthen the relations of classical job resources (i.e., autonomy and learning opportunities) with well-being outcomes. The results in a large, representative sample of Dutch employees (N = 4009) show that a predominant intrinsic work orientation strengthened the negative association of learning opportunities with emotional exhaustion as well as the buffering role of autonomy for the health-impairing impact of workload. With respect to work engagement, a predominant intrinsic work orientation strengthened the positive association of autonomy, the expected boosting impact of workload on the stimulating association of autonomy, as well as the—rather unexpected—attenuating impact of workload on the positive association of learning opportunities with work engagement. Although not all hypotheses were confirmed, in general, results point at the importance and practical relevance of personal resources in the realm of the Job Demands–Resources model.     

Priming of Pop-out in Visual Search: A Comparison of Young and Old Adults

An experiment examined potential age-related differences in priming of pop-out (Maljkovic & Nakayama, 1994, 1996, 2000; McPeek, Maljkovic & Nakayama, 1999), an implicit, memory-based phenomenon that facilitates repeated gaze or attention shifts between visually similar stimuli. Older and younger adults performed a visual search task requiring them to judge the orientation of a color singleton target. Trial-to-trial repetition of target color and/or target position primed attentional selection for both age groups, producing faster and more accurate responses. Age-related increases in the strength of priming by target color appeared to arise from generalized slowing in older observers’, but marginal age-related increases in the strength of priming by target position remained even after transformation to account for generalized slowing.     

Within-session practice eliminates age differences in cognitive control

ABSTRACT

Previous research employing short-term practice and long-term training have been successful in reducing cognitive control deficits in the elderly. The goal of this study was to examine the effect of practice within session on a demanding cognitive control task. Nineteen older adults and 16 young adults performed 720 trials of a cued version of the Stroop task, in which an instructional cue is presented before each individually presented Stroop stimulus. Statistical analyses focused on the most difficult color-naming condition in task-switching blocks. Overall, participants showed faster reaction times and decreased errors with practice, particularly on incongruent trials. Older adults showed a greater reduction in errors with practice than young adults. Moreover, older adults, but not young adults, showed a reduction in errors and reaction times with practice on incongruent trials. Findings further suggest that practice reduces age-related differences in cognitive control. Improvements in cognitive control functioning has implications for treating functional deficits in older adults.     

Self-efficacy,Work, and Psychological Outcomes in a Public Service Context

The study examined the prediction of psychological outcomes (conceptualized as psychological well-being and engagement) by general self-efficacy (GSE) and work context (conceptualized as job demands and job resources). The role of GSE as a moderator between work context and psychological outcomes was also examined in a cross-sectional survey of a sample of public sector employees (N = 459: males = 151, females = 273, and age ranging between 25 and 55). Multiple regression analyses showed that job demands and resources and GSE significantly predict both psychological well-being (positive affect, negative affect and satisfaction with life) and engagement (vigour and dedication). GSE moderated the relationship between work context and psychological outcomes. Work contexts characterised by a preponderance of job resources appear to facilitate both satisfaction with life and dedication.     

The spiritual wellness of Beyers Naudé: A psychobiographical study of a South African anti-apartheid theologian

The study explores and describes Beyers Naudé's (1915–2004) spiritual wellness across his lifespan. Naudé's life history was uncovered through the systematic collection and analyses of life history materials. Data were interpreted applying the Wheel of Wellness model (WoW) by Sweeney and Witmer (1991 Sweeney, T. J., & Witmer, J. M. (1991). Beyond social interest: Striving toward optimum health and wellness. Journal of Individual Psychology, 47(4), 527–540. Retrieved from http://www.utexas.edu/utpress/journals/jip.html [Google Scholar], 1992). Findings suggest that spirituality, as the major life task of the WoW, characterised Naudé's earlier years and also epitomised his later years. Underlying life-span and life-space influences included important life-forces such as the roles of the community, religion, government and politics in his life. Hope and optimism embodied Naudé's belief about promoting and preserving human dignity, human rights and respect for life.
