BACKGROUND Feedback learning is essential for behavioral development. We investigated feedback learning in relation to behavior problems after pediatric traumatic brain injury (TBI). METHOD Children aged 6-13 years diagnosed with TBI (n = 112; 1.7 years post-injury) were compared with children with traumatic control (TC) injury (n = 52). TBI severity was defined as mild TBI without risk facto...

We tested changes in cortical functional response to auditory patterns in a configural learning paradigm. We trained 10 human listeners to discriminate micromelodies (consisting of smaller pitch intervals than normally used in Western music) and measured covariation in blood oxygenation signal to increasing pitch interval size in order to dissociate global changes in activity from those specifi...

We were interested in divising a relatively simple quantitative technique that could be used on a routine clinical basis for wall motion analysis. Three quantitative methods of left ventricular (LV) regional analysis were compared in the 30 degrees right anterior oblique and 60 degrees left anterior oblique projection. The control group consisted of 17 patients with qualitatively normal LV wall...

OBJECTIVES Area-based measures of socio-economic status are increasingly used in population health research. Based on previous research and theory, the Canadian Marginalization Index (CAN-Marg) was created to reflect four dimensions of marginalization: residential instability, material deprivation, dependency and ethnic concentration. The objective of this paper was threefold: to describe CAN-M...

visual representations are those that use conventional symbols to represent the relevant elements of a problem’s cover story. For example, the top portion of Figure 1 illustrates the conventional circuit symbols of the following problem: “Consider two resistors with resistance values R1 6 and R2 12 connected in parallel to a voltage source with V 9 V. Find the total resistance of this circuit.”...

The present study is part of a series of experiments, where we analyze why and how damage of the rat's dorsal hippocampus (dHC) can enhance performance in a sequential reaction time task (SRTT). In this task, sequences of distinct visual stimulus presentations are food-rewarded in a fixed-ratio-13-schedule. Our previous study (Busse and Schwarting, 2016) had shown that rats with lesions of the ...

BACKGROUND Impairment of spatiotemporal visual processing in amblyopia has been studied extensively, but its effects on visuomotor tasks have rarely been examined. Here, we investigate how visual deficits in amblyopia affect motor planning and online control of visually-guided, unconstrained reaching movements. METHODS Thirteen patients with mild amblyopia, 13 with severe amblyopia and 13 vis...

When people predict the future behavior of a person, thinking of that target as an individual decreases the accuracy of their predictions. The present research examined one potential source of this bias, whether and why predictors overweight the atypical past behavior of individuals. The results suggest that predictors do indeed overweight the atypical past behavior of an individual. Atypical p...

Adults with a history of unilateral amblyopia and abnormal binocularity have a range of visual deficits, with some of the 'higher' levels ones generalizing to their dominant (non-amblyopic) eye and linked to widespread binocular cortical network dysfunctions. Our interests are in how these problems also impact on their hand action control in real-world situations. We investigated whether eye-ha...

Traditionally, people use the information difference in one image to distinguish the different area or to extract the object from the background, for example, the classification uses the difference of reflection or texture of different area or classes [1, 2, 3 ]. And in the field of red tide or oil spill abnormal detection, people usually use the experienced value, such as the reflection, SST o...
