The Necessary Limits to Temptation: The Turnkey Project

In case of special engineering projects of important relevance it is interesting to pay attention to several possible risks; some of them are in the field of morality or ethics. Due to the social importance of these risks, additional considerations or even additional warranties are justified.     

Mental models in propositional reasoning and working memory's central executive

We examine the role of working memory's central executive in the mental model explanation of propositional reasoning by using two working memory measures: the classical “reading span” test by Daneman and Carpenter (1980 Daneman, M. and Carpenter, P. A. 1980. Individual differences in working memory and reading. Journal of Verbal Learning and Verbal Behavior, 19: 450–466. [Crossref] , [Google Scholar]) and a new measure. This new “reasoning span” measure requires individuals to solve very simple anaphora problems, and store and remember the word solution in a growing series of inferential problems. We present one experiment in which we check the involvement of the central executive in conditional and disjunctive inference tasks and compare predictions of the new reasoning span test with those of the classical reading span test. The results of the experiment confirm that reasoning responses, which according to mental model theory require high cognitive work, are predicted by working memory measures. Results also show that some reasoning responses are probably obtained by means of superficial biases or strategies that do not load working memory. The reasoning span test, which involves the central executive to a greater degree, predicts reasoning performance better than the reading span test. The significance and possibilities of the new measure in studying reasoning are discussed.

The state version of the recovery experience questionnaire: A multilevel confirmatory factor analysis

Although many studies in the field of recovery from work utilize a quantitative diary design, little is known about the validity of the daily measures used in such studies. The present study analyses the factor structure of the state version of the Recovery Experience Questionnaire (REQ) on the between-person (trait) and within-person (state) levels. A total of 127 employees participated in the study. Most of them filled out the questionnaire on three consecutive workdays (N = 375 observations). Results of multilevel confirmatory factor analyses (MCFA) showed that a four-factor model fit the data better than alternative models at both levels of analysis (between and within). In addition, some factor loadings of the four recovery experience dimensions (particularly for relaxation and control) were lower on the day level as compared to the general level. Nevertheless, we conclude that both state and trait versions of the REQ show good psychometric properties. Implications for future research on recovery are discussed.     

Organizational justice and extrarole customer service: The mediating role of well-being at work

The purpose of this article is to propose and test a model of extrarole customer service (ERCS). We propose that organizational justice (distributive, procedural, interpersonal, and informational) promotes well-being at work (low burnout and high engagement). Well-being at work, in turn, engenders more effective ERCS. Thus, well-being at work is considered a mediator of the relationships from organizational justice to ERCS. This fully mediated model was compared to an alternative fully direct model. The sample consisted of 317 contact employees who were working in the Spanish service sector. The results of structural equation modelling supported the importance of the mediating role of the positive side of well-being at work (engagement) in the relationship between organizational justice and ERCS. The article concludes with a discussion of the theoretical and managerial implications.     

Adult Age Differences in Attention to Semantic Context

ABSTRACT

In three experiments age differences in attention to semantic context were examined. The performance of younger adults (ages 18–29 years) and older adults (ages 60–79 years) on a semantic priming task indicated that both age groups could use information regarding the probability that a prime and target would be related to flexibly anticipate the target category given the prime word (Experiment 1). The timing by which target expectancies were reflected in reaction time performance was delayed for older adults as compared to younger adults, but only when the target was expected to be semantically unrelated to the prime word (Experiment 2). When the target and prime were expected to be semantically related, the time course of priming effects was similar for younger and older adults (Experiment 3). Together the findings indicate that older adults are able to use semantic context and the probability of stimulus relatedness to anticipate target information. Although aging may be associated with a delay in the timing by which controlled expectancies are expressed, these findings argue against an age-related decline in the ability to represent contextual information.     

A set of high quality colour images with Spanish norms for seven relevant psycholinguistic variables: The Nombela naming test

ABSTRACT

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.     

Influence of Training in Artistic Skills on Mental Imaging Capacity

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.     

Vividness and Control of Mental Imagery and the Components of In-Depth Drawing

The aim of this study was to examine the associations of control and vividness of mental imagery on performance in several components of in-depth drawing in a sample of fine arts undergraduates. The sample consisted of 56 second-year undergraduates (44 women and 12 men, mean age = 21.18 years) from the Fine Arts Faculty of Vigo University, Pontevedra, Spain. Participants were required to undertake a plastic art assignment focusing on the pictorial representation of space. Participants scoring high on the image control test obtained higher scores on the spatial analysis and in the formal construction of a work than participants with poor image control. Further research involving spatial image performance tests and mental image rotation tests is proposed.     

Event-sequence Analysis of Appraisals and Coping during Trapshooting Performance

This study describes appraisal and coping patterns of Portuguese trapshooters during competition, via post-performance retrospective verbal reports. Probabilities that an event (e.g., missed target) is followed by another event (e.g., negative appraisal) were calculated and state transitional diagrams were drawn. Event-sequences during critical and non-critical performance periods were compared. Negative appraisals were most likely before and after missed targets and hits with the second shot. Positive appraisals were most likely before problem-focused coping and after emotion-focused coping. These findings support the process view of coping by illustrating that athletes cope with a variety of situations via a complex set of appraisals.
