The purpose of the study was a description of hemispheric specialization characteristics of normally developing right- and left-handed children and determination of what differences in such characteristics, if any, existed between young normally developing and older slowly developing children. With dichaptic and tachistoscopic methods, hemispheric specialization characteristics of 15 slowly developing children (5-0 to 9-6 yr.) and 25 normally developing children (6-0 to 6-11 yr.) were assessed. Latencies and the number of correct responses were analyzed. Both right- and left-handed normally developing 6-yr.-olds showed considerable evidence of bilateralization of hemispheric functions for spatial and verbal information processing; slowly developing children exhibited unusual patterns of hemispheric specialization usually opposite those typically expected in children or adults. Response latency measures of performances of slowly developing children suggested a bilateralization of hemispheric function for processing of verbal and spatial information; number of correct responses indicated that lateralization of such functions was present.

Do So

Although not previously addressed by researchers of spatial cognition or affect, the combination of spatial and affective information is essential for many approach and avoidance behaviors, and thus for survival. We provide the first evidence that through incidental experience, people form representations that capture correlations between affective and spatial information. Participants were able to do so even when the correlation was weak, they were not told to look for the correlation, and the stimuli varied on multiple other dimensions besides valence. In addition, people were more sensitive to the presented correlation when stimuli were negative than when they were positive. This asymmetry in representation may stem from underlying differences in the activation functions for positive and negative hedonic information processing.

Background. The aim of this study was to assess visual information processing and cognitive functions in unaffected siblings of patients with schizophrenia, bipolar disorder and control subjects with a negative family history.Methods. The siblings of patients with schizophrenia (N = 25), bipolar disorder (N = 20) and the controls subjects (N = 20) were matched for age, education, IQ, and psychosocial functioning, as indexed by the Global Assessment of Functioning scale. Visual information processing was measured using two visual backward masking (VBM) tests (target location and target identification). The evaluation of higher cognitive functions included spatial and verbal working memory, Wisconsin Card Sorting Test, letter fluency, short/long delay verbal recall and recognition.Results. The relatives of schizophrenia patients were impaired in the VBM procedure, more pronouncedly at short interstimulus intervals (14, 28, 42 ms) and in the target location task. Marked dysfunctions were also found in the spatial working memory task and in the long delay verbal recall test. In contrast, the siblings of patients with bipolar disorder exhibited spared performances with the exception of a deficit in the long delay recall task.Conclusions. Dysfunctions of sensory-perceptual analysis (VBM) and working memory for spatial information distinguished the siblings of schizophrenia patients from the siblings of individuals with bipolar disorder. Verbal recall deficit was present in both groups, suggesting a common impairment of the fronto-hippocampal system.

This article aims to reveal interaction between verbal intelligence and efficiency of intentional and incidental verbal information processing. Participants were exposed to pairs of words about which they have to decide whether a city name was presented in each pair. Thus, semantics of words was processed intentionally, whereas their phonemic features (rhymed vs. unrhymed pairs) were processed incidentally. The efficiency of stimuli processing was estimated in two different cognitive tasks – word free-recall task and word usage in new creative task. It was found that verbal intelligence was positively correlated with number of recalled stimuli which were congruent to both intentional and incidental processing conditions. Moreover, verbal intelligence was positively correlated with usage of incongruent stimuli which were processed incidentally in creative task. The results are discussed in terms of contemporary frameworks of information processing in verbal tasks.

According to the official statistics the areas of abandoned agricultural land in Lithuania are gradually decreasing, but very slightly. The aim of this study is to research spatial determination and abandoned land classification in the territory of Vilnius District Municipality. Vilnius District Municipality was chosen for the research because it, although located near the capital of the country and has a high population density, it is still the district having the largest percent of abandoned land plots. A fast, cost-effective and sufficiently accurate method for determination of abandoned land plots would allow to constantly monitor, to fix changes and foresee the abandoned land plots reduction possibilities. In the study there was used the multispectral RGB and NIR color Sentinel-2 satellite images, the layer of the administrative boundary of Vilnius County and layer of abandoned agriculture land, which is available in Lithuanian Spatial Information Portal (www.geoportal.lt). The data was processed by Geographic Information System (GIS) techniques using classical classification Region Growing Algorithm. The research shows that NIR image classification result is more reliable than the result from RGB images.
