Journal of Experimental Psychology: Human Perception and Performance, 2023 Semantic context effects in picture naming and categorization tasks are central to the development and evaluation of current models of word production. When pictures are named in a semantically blocked context, response latencies are delayed. Belke (2013) found that when the naming task was replaced with a semantic categorization task (natural vs.

When Meaning Is Not Enough: Distributional and Semantic Cues to Word Categorization in Child Directed Speech [PDF]
Frontiers in Psychology, 2017 One of the most important tasks in first language development is assigning words to their grammatical category. The Semantic Bootstrapping Hypothesis postulates that, in order to accomplish this task, children are guided by a neat correspondence between ...

Neural dynamics of semantic categorization in semantic variant of primary progressive aphasia [PDF]
eLife, 2021 Semantic representations are processed along a posterior-to-anterior gradient reflecting a shift from perceptual (e.g., it has eight legs) to conceptual (e.g., venomous spiders are rare) information. One critical region is the anterior temporal lobe (ATL)

Specificity effect in concrete/abstract semantic categorization task. [PDF]
Cogn ProcessAbstract Concrete concepts ( banana ) are processed faster and more accurately than abstract ones ( belief ). This phenomenon, supported by empirical studies, is known as the concreteness effect. However, recent research indicates that

Processing of auditory novelty in human cortex during a semantic categorization task. [PDF]
Hear ResAuditory semantic novelty - a new meaningful sound in the context of a predictable acoustical environment - can probe neural circuits involved in language processing. Aberrant novelty detection is a feature of many neuropsychiatric disorders. This large-scale human intracranial electrophysiology study examined the spatial distribution of gamma and ...

Pupillometric and behavioural evidence shows no differences between polyseme and homonym processing
Acta Psychologica, 2023 Ambiguous words can have related meanings (polysemes, e.g., newspaper) or unrelated meanings (homonyms, e.g., bat). Here we examined the processing of both types of ambiguous words (as well as unambiguous words) in tasks of increasing level of semantic ...

The Impact of Stimuli Color in Lexical Decision and Semantic Word Categorization Tasks [PDF]
Cognitive Science, 2019 AbstractIn two experiments, we examined the impact of color on cognitive performance by asking participants to categorize stimuli presented in three different colors: red, green, and gray (baseline). Participants were either asked to categorize the meaning of words as related to the concepts of “go” or “stop” (Experiment 1) or to indicate if a neutral ...

From perceptual to language-mediated categorization [PDF]
, 2014 From at least two months onwards, infants can form perceptual categories. During the first year of life, object knowledge develops from the ability to represent individual object features to representing correlations between attributes and to integrate ...

Generative Multi-Task Learning for Text Classification
IEEE Access, 2020 Multi-task learning leverages potential correlations among related tasks to extract common features and yield performance gains. In this paper, a generative multi-task learning (MTL) approach for text classification and categorization is proposed, which ...

Top-down and bottom-up modulation of language related areas – An fMRI Study
BMC Neuroscience, 2003 Background One major problem for cognitive neuroscience is to describe the interaction between stimulus and task driven neural modulation. We used fMRI to investigate this interaction in the human brain.
