Spatial orientation in construction divers - are there associations with diving experience?

Abstract

Despite possible positive selection effects in long-term construction divers, these results may have implications for health care of middle-aged divers who are exposed to critical depths of more than 60 meter sea water (msw).

Navigational place learning in children and young adults as assessed with a standardized locomotor search task

“…Therefore, the exact location of the detector was shown if the participant had moved close enough to the respective location, but the task was supposed to exclude algorithmic strategies. This was checked by an analysis similar to those undertaken in a clinical experiment with Parkinsonian patients and healthy controls (Leplow et al, 2002) and in an experiment with construction divers (Leplow, Tetzlaff, Ho Èll, Zeng, & Reuter, 2001). By this method, the path patterns of each trial were recorded and analysed with respect to non-spatial patterns.…”

Componentes psicológicos de la adaptación subacuática

“…También guardan estrecha relación con los cambios que se producen en el aprovechamiento de las capacidades humanas y en las reacciones conductuales bajo el agua, al existir la posibilidad de narcosis y modificación de la activación psicofisiológica 26,[38][39][40][41][42][43][44] . Los procesos psicológicos necesarios para realizar actividades productivas bajo el agua son los habituales en la superficie de la tierra, como percepción, memoria, aptitudes espaciales, elaboración de información, procesos de decisión, aptitudes psicomotoras,… pero deben aplicarse en condiciones ambientales adversas y ante multitud de variables inhibidoras.…”

Evidence that mammalian sex ratios at birth are partially controlled by parental hormone levels around the time of conception

“…Meanwhile the extensive literature on the harmful effects of recreational (McQueen et al 1994) and professional (Leplow et al 2001, Ross et al 2007) diving -even in the absence of accidents and decompression illness -is worth noting. These harmful effects may at least be suspected of being caused by or associated with endocrine change.…”
