25 The purpose of this study was to quantify how volitional control of hip torque relates to 26 walking function post-stroke. Volitional phasing of hip flexion and extension torques was 27 assessed using a load-cell-instrumented servomotor drive system in 11 chronic stroke subjects 28 and 5 age-matched controls. Hips were oscillated from approximately 40 degrees of hip flexion 29 to 10 degrees ...

This paper presents a theory of motivational analysis , the construction of volitional explanations to describe the planning behavior of agents. We discuss both the content of such explanations, as well as the process by which an understander builds the explanations. Explanations are constructed from decision models, which describe the planning process that an agent goes through when considerin...

Recent studies suggest that none of the behaviors of the vertebrate CNS are fixed responses incapable of change. Even the simplest reflex of all, the two-neuron, monosynaptic spinal stretch reflex (SSR), undergoes adaptive change under appropriate circumstances. Operantly conditioned SSR change occurs gradually over days and weeks and is associated with a complex pattern of CNS plasticity at bo...

Drawing on the Health Adversity Risk Model, this study examines relationship between mental health and sexual risk behaviors in British European Union (EU) university students United Kingdom. Four hundred thirty-one undergraduate completed a cross-sectional survey. Data were analyzed using independent samples t-tests, multiple regression structural equation modeling. Results showed that female ...

Mental illness may be manifested in the impairment of understanding or of volitional control. Impairment of understanding may be manifested in delusions. Impairment of volitional control is shown when a person is unable to act in accordance with good reasons that he himself accepts. In order for an impairment of understanding or of self-control to exculpate, the offence must be causally connect...
