The bullied who bullies: the reciprocal relationship between victim and aggressor in workplace bullying situations

The aim of this study was to explore longitudinal relationships between organizational factors (workload and procedural justice) and targets and perpetrators of workplace bullying. We compared several causal models (baseline or stability, normal, reversed and reciprocal models). The sample comprised 286 employees from two companies in Madrid, and we used a time-lag of one year. Results of structural equation modeling analyses showed that reciprocal model fit the data the best. We found that T1 workload was related positively to T2 target of bullying, and T1 procedural justice was related negatively to T2 target of bullying. There was a significant reverse effect of T1 target of bullying on T2 workload. Furthermore, we found a reciprocal relationship between being the target and the perpetrator of bullying. Overall, these findings emphasize the need to extend the traditional causal models of workplace bullying to more dynamic approaches.

Some psychometric properties of the Spanish version of the Clarity of Auditory Imagery Scale

Few tests have been designed to measure auditory imagery. This study assessed the factor structure and internal consistency of the Spanish version of the Clarity of Auditory Imagery Scale (CAIS). Participants were 234 undergraduate students (M age = 19.6 yr.). Internal consistency reliability estimated by Cronbach's alpha was .82. In a principal components analysis followed by varimax orthogonal rotation, five factors were identified. Scores correlated moderately and positively with ratings on the Vividness of Visual Imagery Questionnaire-2 and negatively on the auditory scale of Betts' Questionnaire Upon Mental Imagery, but weakly and negatively with scores on the Measure of the Ability to Form Spatial Mental Imagery.     

Inhibitory sensory preconditioning.

In two experiments rats were preexposed to neutral stimuli. Both experiments used a between-subjects design in which a paired group was preexposed to intermixed presentations of A --> Band AX, and an unpaired control group was preexposed to intermixed presentations of A, B, and AX. After the conditioning of B, in Experiment 1, conditioned responding to X was acquired more slowly in the paired than in the unpaired group. Furthermore, in Experiment 2, X reduced conditioned responding to a separately trained excitor in a summation test but only in the paired group. Together, these results provide evidence of an inhibitory form of sensory preconditioning.     

La Evolucion de la filosofia de Wittgenstein

Summary The author claims that there is a basic difference between theTractatus and thePhilosophical Investigations; despite Bernstein's and O'Brien's claims to the contrary, there are, indeed, two Wittgensteins. Yet, to ascertain the difference between both we must look at Wittgenstein's conceptions of philosophy rather than at his views on logic and language. Wittgenstein's different, and even divergent, views on logic and language are grounded on his two views on philosophy and not the other way around. At the same time, Wittgenstein's views on philosophy are caused by his ways of conceiving the scope of philosophical activity in regard to language. Both in theTractatus and in thePhilosophical Investigations, Wittgenstein points out what is important in language for philosophy, but in each case he reaches very different conclusions. Now, when all is said, there remains one unifying factor in all of Wittgenstein's investigations: it is the question of the logic of language, which shifts positions from theTractatus to theInvestigations, so that what was earlier a hidden structure becomes later the grammar of its indefinitely complexe uses.     

Transcortical motor aphasia: One or two aphasias?

The name "transcortical motor aphasia" has been used to refer to two different types of language alterations: damage in the left supplementary motor area and Luria's dynamic aphasia. It is proposed that they represent two types of language disturbances different enough to be considered two different forms of aphasia.     

Mastery goal orientation and cognitive ability effects on performance in learner‐guided training

To conserve resources, organizations are increasingly turning to learner‐guided training methods in which workers are given control over when, how, and what they cover in the learning process. However, the impact of individual differences such as goal orientation and cognitive ability has not been adequately addressed in learner‐guided training. This study seeks to advance our knowledge of how these differences affect performance through previously unexplored pathways. Specifically, we examined the indirect effects of mastery goal orientation and cognitive ability on post‐training performance in a learner‐directed training context. Findings indicate that off‐task thoughts mediate the positive effect of mastery goal orientation on post‐training performance, while declarative knowledge mediates the positive effect of cognitive ability on post‐training performance.     

Internal consistency and construct validity of two versions of the Revised Vividness of Visual Imagery Questionnaire

The Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1973) is the questionnaire most extensively used to measure imagery vividness, but two newer versions have been developed. In this study, the reliability and construct validity of these two measures were assessed: the Vividness of Visual Imagery Questionnaire-2 (VVIQ-2) and the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQ-RV). A total of 206 undergraduate psychology students completed both questionnaires, and to assess construct validity, they also completed the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ), Betts' Questionnaire Upon Mental Imagery (Betts' QMI), and the Measure of Ability to Form Spatial Mental Imagery (MASMI). Internal consistency reliability for both was high, with the VVIQ-RV having a Cronbach's alpha of .96, and the VVIQ-2 an alpha of .91. The construct validity of the VVIQ-RV and the VVIQ-2 was supported by the high correlations they had with the other three measures of imagery, which were all close to .50, and the very small correlations (.06-.07) they had with the Verbal scale of the OSIVQ, indicating that they validly measured the imagery construct. Thus, the findings support the two versions as equally valid psychometric instruments for measuring image vividness.     

"Binaural rivalry": dichotic listening as a tool for the investigation of the neural correlate of consciousness

Since about two decades neuroscientists have systematically faced the problem of consciousness: the aim is to discover the neural activity specifically related to conscious perceptions, i.e. the biological properties of what philosophers call qualia. In this view, a neural correlate of consciousness (NCC) is a precise pattern of brain activity that specifically accompanies a particular conscious experience. Almost all studies aimed at investigating the NCC have been carried out in the visual system. One of the most promising paradigms is based on sensory stimuli which elicit bistable percepts, as they allow to decouple subjective perception from the characteristics of the physical stimulation. Such kind of perception can be produced in the visual modality by using particular images (e.g. Rubin's vase/face figure) or by presenting two dissimilar stimuli separately to the two eyes (binocular rivalry). The stimuli compete for perceptual dominance and each image is visible in turn for a few seconds, while the other is suppressed. The use of this methodology has led to important findings concerning visual consciousness, which are briefly discussed. For the investigation of auditory consciousness, a similar stimulation paradigm can be achieved by using dichotic listening, consisting in two different stimuli presented each to one ear, which compete for perception (binaural rivalry). The principal aim of the present mini-review is to discuss the few contributes facing the issue of auditory consciousness and to advance the use of dichotic listening and binaural rivalry as valid tools for its investigation.     

Mediated moderation or moderated mediation: relationship between length of unemployment, resilience, coping and health

The aim of the present research was to evaluate a model of mediated moderation vs. moderated mediation that could explain the relationship between length of unemployment, dispositional resilience, coping styles and depression and social functioning of Venezuelan unemployed individuals. Self-report measures were administered to a sample of 328 unemployed residents in Caracas, Venezuela. Results indicated that emotional coping acted as a mediator in the relationship between resilience and depression. Individuals with greater resilience used more detachment coping when unemployment was longer, while individuals with poorer resilience in the same situation used less avoidance coping. Resilience acted as a protective moderating factor between longer periods of unemployment and social functioning, a process mediated by detachment coping. Overall, results supported a mediated moderation model, with resilience as the moderating factor and coping as the mediator in the relation between stress due to the length of unemployment and well-being.
