Perspective and strategy interactively modulate sex differences in a 3D navigation task

AbstractSex differences in navigation performance have been attributed to sex differences in information processing during navigation. Perspective refers to the viewpoint of the navigator, with previous work suggesting that men tend to use an allocentric perspective, while women tend to use an egocentric perspective during navigation. Furthermore, different navigation strategies may be used when moving from point A to B, with previous work suggesting that men tend to use a Euclidian strategy, while women tend to use a landmark-based strategy. However, it has not been studied whether perspective and strategy affect sex differences in navigation interactively or independently of each other. The present study aimed to investigate the interactive effects of perspective and strategy on sex differences in a 3D navigation task. In different levels of the task, perspective and strategy were modulated in a 2  × 2 design via different instructions. Potential mediating effects of video gaming experience and sex hormone levels were addressed. We found that men outperformed women in all levels of the navigation task. However, the male advantage was more pronounced using the allocentric perspective comp ared to the egocentric perspective. When using the allocentric perspective, men showed better performance using a Euclidian strategy while women showed better performance using a landmark-based strategy. The strategy did not modulate performance under the egocentric pers...

Authors: Nagy P, Molnar B, Nemes B, Schupbach P, Windisch P Abstract The aim of this case series was the histologic evaluation of guided tissue regeneration utilizing deproteinized bovine bone mineral (DBBM) when regenerative surgery was combined with (test) or without (control) early orthodontic tooth movement. Core biopsy samples were harvested from previously defected sites after 9 months. The histologic section showed integration of DBBM particles in newly formed bone in the apical and middle thirds of the defect, while in the coronal part, graft materials were mainly embedded in connective tissues in the contr...

Authors: Al Balbeesi HO, Al Kawari HM, Al Tamimi AS, Al Mubarak I, Al Ibrahim KI, Divakar DD Abstract In the present study, the authors evaluated the association of canine impaction with different skeletal discrepancies in two planes of space (sagittal and vertical). Cephalometric and orthopantomographic radiographic images of 45 patients with one or more impacted canines were used in this retrospective study. Five radiographic morphologic parameters-ANB angle, canine angulation, angle between the Frankfort horizontal plane and the mandibular plane (FH-MP), Wits appraisal analysis, and axial inclination of the maxi...
