Neuropsychological functioning, in relation to positive and negative symptoms in psychotic major depression (PMD), has not been as thoroughly studied as it has been in schizophrenia. Thus, the current study investigated the associations between positive and negative symptoms with cognitive functioning, with an emphasis on verbal memory in PMD. Attention, working memory, and the executive functi...

OBJECTIVE The aim of this study was to develop a presurgical magnetoencephalography (MEG) protocol to localize and lateralize expressive and receptive language function as well as verbal memory in patients with epilepsy. Two simple language tasks and a different analytical procedure were developed. METHODS Ten healthy participants and 13 epileptic patients completed two language tasks during ...

OBJECTIVE The current investigation examined verbal memory in idiopathic non-dementia Parkinson's disease and the significance of the left entorhinal cortex and left entorhinal-retrosplenial region connections (via temporal cingulum) on memory impairment in Parkinson's disease. METHODS Forty non-demented Parkinson's disease patients and forty non-Parkinson's disease controls completed two ver...

BACKGROUND Efficient memory functions are important to the development of cognitive and functional skills, allowing individuals to manipulate and store information. Theories of memory have suggested the presence of domain-specific (i.e. verbal and spatial) and general processing mechanisms across memory domains, including memory functions dependent on the prefrontal cortex (PFC) and the hippoca...

The neurocognitive and social cognitive correlates of two types of formal thought disorder (i.e., bizarre-idiosyncratic and concrete thinking) were examined in 47 stable outpatients with schizophrenia. Both types of thinking disturbance were related to impairments in verbal learning, intrusions in verbal memory, immediate auditory memory, sustained attention, and social schema knowledge. Distra...

Background: Acoustic noise is one of the universal pollutants of modern society. Although the high level of noise adverse effects on human hearing has been known for many years, non-auditory effects of noise such as effects on cognition, learning, memory and reading, especially on children, have been less considered. Factors which have negative impact on these features can also have a negat...

Musical memory was tested in Alzheimer patients and in healthy older adults using long-term and short-term memory tasks. Long-term memory (LTM) was tested with a recognition procedure using unfamiliar melodies. Short-term memory (STM) was evaluated with same/different judgment tasks on short series of notes. Musical memory was compared to verbal memory using a task that used pseudowords (LTM) o...
