Inverted-U function relating cortical plasticity and task difficulty.
Many psychological and physiological studies with simple stimuli have suggested that perceptual learning specifically enhances the response of primary sensory cortex to task-relevant stimuli. The aim of this study was to determine whether auditory discrimination training on complex tasks enhances primary auditory cortex responses to a target sequence relative to non-target and novel sequences. ...
متن کاملStudents’ Oral Assessment Considering Various Task Dimensions and Difficulty Factors
This study investigated students’ oral performance ability accounting for various oral analytical factors including fluency, lexical and structural complexity and accuracy with each subcategory. Accordingly, 20 raters scored the oral performances produced by 200 students and a quantitative design using a MANOVA test was used to investigate students’ score differences of various levels of langua...
متن کاملSpeed tuning of direction repulsion describes an inverted U-function
Direction repulsion describes the phenomenon in which observers typically overestimate the direction difference between two superimposed motions moving in different directions (Marshak & Sekuler, Science 205 (1979) 1399). Previous research has found that, when a relatively narrow range of distractor speeds is considered, direction repulsion of a target motion increases monotonically with increa...
متن کاملLearning under stress: the inverted-U-shape function revisited.
Although the relationship between stress intensity and memory function is generally believed to follow an inverted-U-shaped curve, strikingly this phenomenon has not been demonstrated under the same experimental conditions. We investigated this phenomenon for rats' performance in a hippocampus-dependent learning task, the radial arm water maze (RAWM). Variations in stress intensity were induced...
متن کاملInverted-U and Inverted-J Effects in Self-Referenced Decisions
Rating one’s own personality traits is a common self-referential information processing task. The current paper examined the mechanism underlying this sort of trait-rating task by using a PC cursor tracing technique (Shiina, 2011a, b). The target phenomenon of interest was the inverted-U effect observed in trait ratings. The PC cursor tracing technique analyzed response times, tangential veloci...
