Illness perception and affective symptoms in gastrointestinal cancer patients: A moderated mediation analysis of meaning in life and coping.
2019
Objective The character of the mediational relations between illness perception and affective symptoms often depends on the coping strategies used by patients. For example, these relationships may be moderated by meaning in life that plays a buffering role against the negative consequences of cancer. This study examined moderated mediation effects of meaning in life and coping on the relationship between illness perception and affective symptoms in cancer patients. Methods In this cross-sectional research, 317 gastrointestinal cancer patients who were undergoing chemotherapy, radiotherapy, or combined therapy treatments were examined. They completed measures of illness perception, affective…
Health science student teachers' perceptions of teacher competence: A qualitative study.
2019
Abstract Background Health science teacher competence is multifaceted and continuously changing according to national and international healthcare standards. Organizational restructuring and emphasis on cost effectiveness is changing the scope of health science teachers' practical work and their role in healthcare (worldwide). Aim This study aimed to describe student teachers' perceptions of the competencies needed to work as an educator in the healthcare field. Objective of study was to gain new knowledge which can be used in the development of teacher education programs in nursing science and to define a broader definition of the health science educators. Methods A qualitative study was c…
Dance on cortex: enhanced theta synchrony in experts when watching a dance piece
2018
When watching performing arts, a wide and complex network of brain processes emerge. These processes can be shaped by professional expertise. When compared to laymen, dancers have enhanced processes in observation of short dance movement and listening to music. But how do the cortical processes differ in musicians and dancers when watching an audio-visual dance performance? In our study, we presented the participants long excerpts from the contemporary dance choreography of Carmen. During multimodal movement of a dancer, theta phase synchrony over the fronto-central electrodes was stronger in dancers when compared to musicians and laymen. In addition, alpha synchrony was decreased in all gr…
Conscientiousness and Extraversion relate to responsiveness to tempo in dance
2016
Previous research has shown broad relationships between personality and dance, but the relationship between personality and specific structural features of music has not been explored. The current study explores the influence of personality and trait empathy on dancers' responsiveness to small tempo differences between otherwise musically identical stimuli, measured by difference in the amount in acceleration of key joints. Thirty participants were recorded using motion capture while dancing to excerpts from six popular songs that were time-stretched to be slightly faster or slower than their original tempi. Analysis revealed that higher conscientiousness and lower extraversion both correla…
Altered orientation of spatial attention in depersonalization disorder
2013
Difficulties with concentration are frequent complaints of patients with depersonalization disorder (DPD). Standard neuropsychological tests suggested alterations of the attentional and perceptual systems. To investigate this, the well-validated Spatial Cueing paradigm was used with two different tasks, consisting either in the detection or in the discrimination of visual stimuli. At the start of each trial a cue indicated either the correct (valid) or the incorrect (invalid) position of the upcoming stimulus or was uninformative (neutral). Only under the condition of increased task difficulty (discrimination task) differences between DPD patients and controls were observed. DPD patients sh…
The effect of aberrations on objectively assessed image quality and depth of focus
2017
The effects of aberrations on image quality and the objectively assessed depth of focus (DoF) were studied. Aberrometry data from 80 young subjects with a range of refractive errors was used for computing the visual Strehl ratio based on the optical transfer function (VSOTF), and then, through-focus simulations were performed in order to calculate the objective DoF (using two different relative thresholds of 50% and 80%; and two different pupil diameters) and the image quality (the peak VSOTF). Both lower order astigmatism and higher order aberration (HOA) terms up to the fifth radial order were considered. The results revealed that, of the HOAs, the comatic terms (third and fifth order) ex…
Nursing Education in Catalonia: Novice Professionals’ Appraisal of Its Quality and Usefulness. Does Mobility Play a Role?
2020
The present study aimed to examine the relationship between the quality of undergraduate education perceived by novice nurses and their retrospective satisfaction with their education. It also studied the relationships between the perceived usefulness of their education for their current jobs and the quality of the jobs held by novice nursing professionals. The moderator role of mobility in this relationship was also analyzed, as it reflects a boundary condition in which additional preparation or job opportunities may occur. The study used data from the graduates’ survey carried out by the Agència per a la Qualitat del Sistema Universitari de Catalunya (AQU) in 2017. The analysis of data fr…
The remapping of time by active tool-use
2015
Multiple, action-based space representations are each based on the extent to which action is possible toward a specific sector of space, such as near/reachable and far/unreachable. Studies on tool-use revealed how the boundaries between these representations are dynamic. Space is not only multidimensional and dynamic, but it is also known for interacting with other dimensions of magnitude, such as time. However, whether time operates on similar action-driven multiple representations and whether it can be modulated by tool-use is yet unknown. To address these issues, healthy participants performed a time bisection task in two spatial positions (near and far space) before and after an active …
Dissociating effect of upper limb non-use and overuse on space and body representations.
2015
Accurate and updated representations of the space where the body acts, i.e. the peripersonal space (PPS), and the location and dimension of body parts (body representation, BR) are essential to perform actions. Because both PPS and BR are involved in motor execution and display the same plastic proprieties after the use of a tool to reach far objects, it has been suggested that they overlap in a unique representation of the body in a space devoted to action. Here we determined whether manipulating actions in space, without modifying body metrics, i.e. through immobilization, induces a dissociation of the plastic properties of PPS and BR. In 39 healthy subjects we evaluated PPS and BR for th…
The role of working memory in the association between number magnitude and space.
2007
In two experiments, participants performed a magnitude comparison task in single and dual-task conditions. In the dual conditions, the comparison task was accomplished while phonological or visuospatial information had to be maintained for a later recall test. The results showed that the requirement of maintaining visuospatial information produced the lack of spatial-numerical association of response codes (SNARC) effect. The SNARC effect was not found even when the performance in the comparison task did not decline, as indicated by a similar distance effect in all conditions. These results show a special role for the visuospatial component of working memory in the processing of spatial rep…
