Brain Sciences Free Full Text Concrete And Abstract Concepts In The concreteness effect (ce), namely a better performance with concrete compared to abstract concepts, is a constant feature in healthy people, and it usually increases in persons with aphasia (pwa). however, a reversal of the ce has been reported in patients affected by the semantic variant of primary progressive aphasia (svppa), a neurodegenerative disease characterized by anterior temporal. Eeg results revealed differences in brain activation between concrete and abstract words. concrete words elicited a stronger response at around 146 ms relative to abstract and control untrained pseudowords, while abstract words only showed a difference relative to control pseudowords at 206 ms.
Brain Sciences Free Full Text Contextual Acquisition Of Concrete The neural mechanisms subserving the processing of abstract concepts remain largely debated. even within the embodiment theoretical framework, most authors suggest that abstract concepts are coded in a linguistic propositional format, although they do not completely deny the role of sensorimotor and emotional experiences in coding it. to our knowledge, only one recent proposal puts forward. The percentage correct responses on the concrete word stimulus sets are shown in fig. 3b.the results for both word sets were considered together. a wilcoxon matched pairs signed ranks test showed that a.z. was significantly less accurate at pointing to the target word in same semantic category arrays than different semantic category arrays (z = 3.62, p < 0.001). Abstract. concepts allow us to make sense of the world. most evidence on their acquisition and representation comes from studies of single decontextualized words and focuses on the opposition. In contrast, the learning of instances of abstract concepts yielded much reduced and only short lived activity. crucially, when conceptual instances were learned in the context of wordforms, circuit activations became robust and long lasting for both concrete and abstract meanings.

Abstract. it is increasingly apparent that sensorimotor information is a constitutive part of conceptual knowledge. yet all concepts, even highly concrete ones (e.g. dog) include information that is abstracted across individual episodes of experience, departing somewhat from direct sensory or motor input. this process of abstraction is the. Unlike prior findings 43,44, our results suggest that the left hemisphere tends to encode exteroceptive and concrete concepts, whereas the right hemisphere tends to encode interoceptive and.
