This study compared the factor structure of the Sensation-Seeking Scale (SSS) in English and American samples, and a new form of the SSS, applicable to both samples, was constructed. Three of the four factors showed good crossnational and cross-sex reliability. English and American males did not differ on the total SSS score, but American females scored higher than English females. Males in bot...

Conventional Difference of Gaussians (DoG) filter is usually used to model the early stage of visual processing. However, the convolution operation used with DoG does not explicitly account for the effects of disinhibition. Because of this, complex brightness contrast illusions such as the White effect cannot be explained using DoG filters. We discovered that a new model explicitly accounting f...

The language ego permeability hypothesis argues that adults have difficulty learning foreign languages, b...

The authors aim to determine if a history of traumatic brain injury (TBI) assessed before dementia onset is associated with a higher risk of neuropsychiatric symptoms after dementia onset. A population-based incident series of people with dementia were assessed for TBI prior to onset of dementia and for neuropsychiatric symptoms after the onset, using the Neuropsychiatric Inventory. Participant...

We present a neural network model that aims to bridge the historical gap between dynamic and structural approaches to personality. The model integrates work on the structure of the trait lexicon, the neurobiology of personality, temperament, goal-based models of personality, and an evolutionary analysis of motives. It is organized in terms of two overarching motivational systems, an approach an...

A number of studies have found that broadband internalizing and externalizing factors provide a parsimonious framework for understanding the structure of psychopathology across childhood, adolescence, and adulthood. However, few of these studies have examined psychopathology in young children, and several recent studies have found support for alternative models, including a bi-factor model with...
