Which is heavier: a pound of lead or a pound of feathers? This classic trick question belies a simple but surprising truth: when lifted, the pound of lead feels heavier--a phenomenon known as the size-weight illusion. To estimate the weight of an object, our CNS combines two imperfect sources of information: a prior expectation, based on the object's appearance, and direct sensory information f...

OBJECTIVE This study describes the sensory processing abilities of children ages 3-10 who sustained a moderate or severe traumatic brain injury (TBI). METHOD We used a prospective, descriptive study design with convenience sampling of 20 children who were admitted to a pediatric neurosurgical unit. Caregivers provided information regarding their child's sensory processing abilities using the ...

Objectives: To further quantify the characteristics of cold-water swimmers, and to examine the potential exercise benefits, weight changes, perceptions of cold tolerance, and safety concerns related to swimming recreationally in

To better understand the possible functional significance of electrophysiological sensory gating measures, response suppression of midlatency auditory event related potential (ERP) components was compared to the mismatch negativity (MMN) and to self-rated indices of stimulus filtering and passive attention-switching phenomena in an age-restricted sample of healthy adults. P1 sensory gating, mea...

OBJECTIVE To assess illness perceptions, self-care behaviours and their relationship in recently diagnosed type 2 diabetes mellitus (T2DM) patients with and without diabetes-related complications. DESIGN Cross-sectional survey among 192 recently diagnosed T2DM patients of whom 23% reported the presence of diabetes-related complications. Illness perceptions and self-care were assessed by the R...

Mind-wandering refers to the occurrence of thoughts whose content is both decoupled from stimuli present in the current environment and unrelated to the task being carried out at the moment of their occurrence. The core of this phenomenon is therefore stimulus-independent and task-unrelated thoughts (SITUTs). In the present study, we designed a novel experience sampling method which permitted t...

This survey covers the potential use of neurophysiological changes as a biomarker in four neuropsychiatric diseases (attention deficit hyperactivity disorder (ADHD), Alzheimer's disease (AD), bipolar disorder (BD), and schizophrenia (SZ)). Great developments have been made in the search of biomarkers in these disorders, especially in AD. Nevertheless, there is a tremendous need to develop an ef...
