Towards an Ecological Model of Prehension
… relationships between hands and objects of prehension. Hand patterns were classified relative to generic action categories of immobilization, displacement, projection, and manipulation. These generic action categories do not embody all prehensile patterns but, do indeed capture a majority, …

Quantifying prehension in persons with stroke post rehabilitation
This study describes the analysis of reaching and grasping abilities of the hemiparetic arm and hand of patients post stroke after a series of interactive virtual reality (VR) simulated training sessions and conventional physical therapy of similar intensity. Six subjects participated in VR …

Neural representations of movement planning within the human prehension system
… Failing to select, prepare or perform correct prehension movements results in dramatic limitations for the affected individual. Whereas we begin to have a better understanding of the neural mechanisms underlying the execution of object-directed movements, less is known about how exactly our …

Observational Intelligence: An Overview of Computational Actual Entities and their Use as Agents of Artificial Intelligence
… their environment through a process called prehension. It is the combined effect of multiple Actual Entities working within a Colony of Prehending Entities that produces emergent, intelligent behavior. It is not always the case that prehension functions for desired behavior are known …

Effect of kinetic degrees of freedom in multi-finger force and moment stabilizing synergies.
… synergies are conditioned by everyday prehension experiences, we hypothesized that moment stabilizing synergies, if existing, would increase with the number of fingers, since all the fingers are generally used for everyday prehension and manipulation tasks, and such tasks require a …

Neurobehavioural representations of observed action viewpoint
… 2 presents motion capture data from a manual prehension task which manipulated observed reach height. Actions were observed from two allocentric viewpoints. The data revealed no differences between viewpoints, but did reveal effects of relative spatial direction congruency. Chapter 3 further …

The development of spatially-accurate reaching behaviour in early infancy
… any tactile-kinesthetic feedback obtained from prehension attempts produces very little modification of young infants reaching behaviour.

Defining feline brachycephaly and benefits of ala vestibuloplasty in the brachycephalic cat
… volume of ocular discharge, more difficulty with prehension, more frequent episodes of dyspnea, less time engaged in physical activity time before becoming dyspneic, slower recovery from activity, and increased lethargy. Owners of BC cats were less likely to report vomiting than owners of non-BC …

Getting a grip on Schizotypy: Elucidating dorsal stream deficits in Schizophrenia Spectrum Disorders
… in kinematic parameters of visually guided prehension. Moreover, the profile of errors across movement type (pointing versus grasping) and target type (stationary versus moving) were posited to more strongly implicate one dorsal substream over the other. Results showed no significant …

Controllo dell'atto di prensione: coinvolgimento dell'area V6A nell'orientamento del polso
Prehension in an act of coordinated reaching and grasping. The reaching component is concerned with bringing the hand to object to be grasped (transport phase); the grasping component refers to the shaping of the hand according to the object features (grasping phase) (Jeannerod, 1981). Reaching and …

Lamb performance, behavior, and body temperatures in hardwood silvopasture systems
… and an audio recording device (1 day) to detect prehension events. Cameras documented lamb behavior every 60 seconds. Forage measurements taken with a rising plate meter indicated greater productivity in the honeylocust silvopasture (5020 ± 30 kg · ha⁻¹ ) compared to the open pasture (4930 ± 30 …
