The Job Demands and Resources Decision Making (JD-R-DM) Model

This study explores the effects of nurses’ daily job characteristics (i.e., job demands and resources) and general work engagement on their daily decision making (i.e., analytical and intuitive) and consequently their daily performance (i.e., task and contextual). Participants completed a baseline questionnaire and a diary for five consecutive days. Results reveal a positive influence of the job demands “work pressure” and “predictability” on analytical decision making. In turn, analytical decision making promotes task performance. Work pressure also negatively influences intuitive decision making which, in turn, stimulates task and contextual performance. However, the job resource (i.e., autonomy) had a nonsignificant relationship with decision making. General work engagement had positive effects on analytical decision making and moderated the relationship between intuitive decision making and contextual performance. For those high on work engagement, the relation was stronger compared to their counterparts low on work engagement. Results corroborate that expanding and testing decision-making theories can increase understanding on how the work environment and engagement influence employee decision making and performance.     

Senility versus Wisdom: The Meaning of Old Age as a Cause for Behavior

Past research links the use of small talk in negotiations to positive outcomes. We posit that men and women may not benefit equally from small talk. Building on stereotype and environmental certainty theories, we propose contexts when male negotiators who small talk are perceived more favorably. Studies 1a/1b show that men enjoy a social boost from small talk when cues for behavior are not strongly articulated. Study 2 identifies a social boost from small talk to both genders when cues for behavior are clearly articulated, but this boost only translates into better deals for men who small talk. Overall, small talk in negotiations has a stronger, more consistent effect for men.     

Delayed oculomotor inhibition in patients with lesions to the human frontal oculomotor cortex: Evidence from a study on saccade averaging

The frontal oculomotor cortex is known to play an important role in oculomotor selection. The aim of the current study was to examine whether previously observed findings concerning the role of the frontal oculomotor cortex in the speed of saccade initiation and oculomotor inhibition might be related to a common underlying role of these areas in oculomotor selection. To this end, six patients with lesions to the frontal oculomotor cortex performed a double stimulus paradigm in which two elements were presented simultaneously in close proximity. Patients performed a block in which no specific task instruction was given and a block in which an instruction was provided about which of the two elements was the target. The rationale behind this manipulation was that the introduction of a specific task instruction would require a stronger involvement of top-down factors. In contrast to the block without a specific task instruction, saccade latencies to the contralesional visual field were longer than the ipsilesional visual field when a task instruction was given. This effect was strongest for saccades that landed away from the target and the distractor, reflecting trials in which strong oculomotor inhibition was applied. The observed deficits can be explained in terms of a slowing of the inhibitory signals associated with the rejection of a distractor. Given the known role of the Frontal Eye Fields and the location of the lesions, we attribute these findings to the Frontal Eye Fields, revealing their important role in the voluntary control of eye movements.     

Mobbing

Bullying at the workplace and its negative effects on mental and physical health are a subject of avid public discussion with the mass media being part of this process. Often bullying at the workplace is assumed to result in somewhat specific consequences due to causal relationships. Contrarily, research suggests relatively complex interactions between bullying and negative health outcomes. Furthermore, the use of the term bullying is inflated, lowering the threshold for a conflict to be categorized in this way. This article reviews the bullying concept: what is the definition of bullying and how common is it in the work environment? What consequences of bullying are discussed in the literature and to what extent are they empirically confirmed? Which causes for bullying are accepted? Having answered these questions it will be discussed why the bullying concept is so popular and why this popularity might counteract more appropriate conceptualizations of the problem.     

Michel Henry's Phenomenology of Aesthetic Experience and Husserlian Intentionality

In his essay 'The Pit and the Pyramid: Introduction to Hegel's Semiology', Jacques Derrida claims that there is a privilege of speech over writing inherent in Hegel's theory of signs. In this paper, I examine Derrida's criticism. While it is to Derrida's credit that he focusses on an area of Hegel's philosophy that has hardly been analysed, his reading is problematic in several regards. After presenting Derrida's main arguments, I pose three questions, the first of which belongs to the realm of subjective spirit, the second to objective spirit, and the third to absolute spirit. I shall then show that Hegel makes several statements in favour of a privilege of writing over speech - statements that are not merely parenthetic or marginal. Moreover, those claims that Hegel makes toward any privilege of speech are in the wrong place, namely, subjective spirit, for them to represent his final point of view.     

The imbalance of oculomotor capture in unilateral visual neglect

Visual neglect has been associated with an imbalance in the level of activity in the saccadic system: activity in the contralesional field is suppressed, which makes target selection unlikely. We recorded eye movements of a patient with hemispatial neglect and a group of healthy participants during an oculomotor distractor paradigm. Results showed that the interfering effects of a distractor were very strong when presented in her ipsilesional visual field. However, when the distractor was presented in her contralesional field, there were no interfering effects when the target was presented in her ipsilesional field. These findings could not be explained by the presence of a visual field defect as revealed by the results of two hemianopic patients. Our results are in line with an imbalance in the level of activity in the saccadic system in visual neglect because visual elements presented in the contralesional field did not compete for saccadic selection.     

Recognising the forest, but not the trees: an effect of colour on scene perception and recognition

Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is 'diagnostic'. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate whether they had seen the images during the study phase. Surprisingly, performance was better for greyscale than for coloured images, and this difference is due to the higher false alarm rate for both natural and man-made coloured scenes. We hypothesized that this increase in false alarm rate was due to a shift from scrutinizing details of the image to recognition of the gist of the (coloured) image. A second experiment, utilizing images without a nameable gist, confirmed this hypothesis as participants now performed equally on greyscale and coloured images. In the final experiment we specifically targeted the more detail-based perception and recognition for greyscale images versus the more gist-based perception and recognition for coloured images with a change detection paradigm. The results show that changes to images are detected faster when image-pairs were presented in greyscale than in colour. This counterintuitive result held for both natural and man-made scenes (but not for scenes without nameable gist) and thus corroborates the shift from more detailed processing of images in greyscale to more gist-based processing of coloured images.
