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.     

Cognitive Development of Lead Exposed Children from Ages 6 to 15 Years: An Application of Growth Curve Analysis

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.     

Goal pursuit in young adulthood: The role of personality and motivation in goal appraisal trajectories across 6 years

The aim of this longitudinal study was to examine changes in the appraisals of personal goals during young adulthood, and to investigate personality and motivation as predictors of goal appraisals. Israeli young adults (N = 284, 46% female) were assessed four times during ages 23–29 and reported on their goal appraisals (goal investment, goal momentum and goal stress), personality (efficacy and self-criticism) and motivation (autonomous motivation, controlled motivation, amotivation). The results showed mean stability for goal investment and momentum, whereas goal stress declined. Efficacy predicted higher goal investment and momentum 6 years later, while self-criticism accounted for individual differences in goal stress. Autonomous motivation predicted higher goal investment and momentum, while amotivation related to higher goal stress.     

Tracking the speech signal – Time-locked MEG signals during perception of ultra-fast and moderately fast speech in blind and in sighted listeners

Blind people can learn to understand speech at ultra-high syllable rates (ca. 20 syllables/s), a capability associated with hemodynamic activation of the central-visual system. To further elucidate the neural mechanisms underlying this skill, magnetoencephalographic (MEG) measurements during listening to sentence utterances were cross-correlated with time courses derived from the speech signal (envelope, syllable onsets and pitch periodicity) to capture phase-locked MEG components (14 blind, 12 sighted subjects; speech rate = 8 or 16 syllables/s, pre-defined source regions: auditory and visual cortex, inferior frontal gyrus). Blind individuals showed stronger phase locking in auditory cortex than sighted controls, and right-hemisphere visual cortex activity correlated with syllable onsets in case of ultra-fast speech. Furthermore, inferior-frontal MEG components time-locked to pitch periodicity displayed opposite lateralization effects in sighted (towards right hemisphere) and blind subjects (left). Thus, ultra-fast speech comprehension in blind individuals appears associated with changes in early signal-related processing mechanisms both within and outside the central-auditory terrain.     

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.
