The relationships between psychological variables and the presence of cancer, its prediction, and the prediction of cancer mortality and course of disease have been studied extensively. From a limited list of about 50 such variables, the following have been the focus of the most intensive research and are discussed in this report: human and animal stress; bereavement; depressed mood; psychosis,...

The insights of ethology-the science of animal behavior from a biological and psychological point of view-were incorporated in the 1950s by the British developmental psychiatrist, John Bowlby, into his attachment theory, which argued that a secure affective base in infancy was critical to the normal development of perception, cognition, learning, and emotion, in addition to that of physical par...

The attentional scope model of rumination describes the links between rumination and attentional breadth. The model postulates that a more narrow attentional scope, caused by negative mood, increases the likelihood that thoughts become repetitive on the same topic, which in turn could exacerbate negative mood and lead to more attentional narrowing. We experimentally tested this model by examini...

Deficiency of Vitamin B12 can have many neurologic sequelae including periperhal neuropathy, visual disturbances, mood and memory changes and subacute combined degeneration (SCD) of the spinal cord1. Macrocytic anemia is also a common finding of B12 deficiency allowing the clinician to arrive at a diagnosis, however neurologic symptoms can be present even in the absence of hematologic changes. ...

Despite recent advances in understanding the pathophysiology of poststroke depression, major questions remain. They include the relative importance of lesion location and size and the confounding effects of time since stroke, age, prior history of depression, and cerebral atrophy. To evaluate these issues, we systematically assessed depressive features, functional status, and brain structure wi...

Recommender systems usually rely on user profiles to generate personalized recommendations. We argue here that such profiles are often too coarse to capture the current user’s state of mind/desire. For example, a serious user that usually prefers documentary features may, at the end of a long and tiring conference, be in the mood for a lighter entertaining movie, not captured by her usual profi...
