Identification And Management Of Impulse Control Disorders Among Individuals With Parkinson’S Disease, Andrew Johnson, H. Hyson, Kaitlyn Roland

Andrew M. Johnson

Although Parkinson’s disease is primarily considered to be a motor disorder, it has inarguable effects on cognition and personality. The cluster of neuropsychiatric sequelae known as impulse-control disorders has been of particular interest in recent years, perhaps owing to the potentially disastrous effects that such behaviors can have on individuals and families. Research has suggested that impulse control disorders are significantly more prevalent among individuals with Parkinson’s disease, particularly with regards to pathological gambling and hypersexuality, and has further suggested that these disorders are significantly and substantively affected by the use of dopamine agonists. Treatment options for impulse control disorders …

Learning From Mistakes: Improving Initial Fingertip Force Scaling By Observing Lifting Errors, Gavin Buckingham, Minnie Tang, Paul Gribble, Melvyn Goodale

Gavin Buckingham

• When lifting objects that are lighter or heaver than we expect them to be, individuals typically misapply forces in a way that reflects their prior expectations of heaviness.

• Because we lift in this predictive way, large and small cubes elicit these characteristic errors even when they are adjusted to have equal mass. Lifters will apply too much force to a large cube and substantially less force to a small cube – errors that are rapidly corrected with repeated lifts (Flanagan & Beltzner, 2000).

• When watching others lift objects, an observer’s motor system automatically reacts in a way …
