OBJECTIVE The authors examined the relationship of neurocognitive function with duration of untreated psychosis, premorbid illness factors, and clinical symptoms to determine whether long duration of untreated psychosis independently compromises cognitive function. METHOD Patients recruited to a study of the effect of an early detection program on the duration of untreated first-episode psych...

the aim of the study was to find whether there is an association between subjective memory complaint and memory impairment and probable underlying psychological conditions. a total of 90 patients with subjective memory complaint enrolled in this study. short history and demographic information were obtained and then the patients underwent memory and mental health assessments, using wechsler mem...

Memory consolidation has been mainly investigated for extended periods, from hours to days. Recent studies focused on memory occurring within shorter seconds minutes. Yet, these explicit sequence learning with fixed rest periods. Our study aimed at determining whether short periods enhance implicit probabilistic and the length of duration influences such offline changes. Participants performed ...

The design of grating-based instruments to handle and condition coherent ultrafast pulses in the extreme-ultraviolet is discussed. The main application of such instruments is the monochromatization of high-order laser harmonics and free-electron-laser pulses in the femtosecond time scale. Broad-band monochromators require the use of diffraction gratings at grazing incidence. A grating can be us...

It was examined whether stimulus modality (auditory vs. visual) affects the retrieval of subjective duration from memory. In 2 experiments a temporal generalization paradigm was used. Participants had to decide whether the previously learned standard duration (400 ms) occurred in the context of comparison stimuli. Two major results were found. (1) Performance was unaffected by the modality of t...

introduction: this study aims to compare the cognitive performance of patients with multiple sclerosis (ms) in the field of autobiographical, prospective and working memory compared to normal people. method: in a causal-comparative study using convenience sampling 200 patients with ms (100 were affected less and 100 were affected more than 2 years (and 100 healthy individuals were matched regar...

On four tests of visual recognition memory Parkinsonian patients obtained normal scores, both immediately and after a delay. They also resembled controls closely in nearly all characteristics of memory. Their performance did not correlate with age, motor disability or disease duration. Parkinson's disease does not, therefore, affect this kind of memory.

potassium bromide (kbr), an old antiepileptic agent, is illegally used in pharmaceutical or food industries to improve the product appearance. kbr has been proven to influence several pathways which are important in memory formation. therefore, the present study aimed to evaluate the effect of kbr on spatial working memory using object recognition task (ort). rats received a single dose of kbr ...
