Abstract
Pictorial stimuli are crucial in psycholinguistic research and clinical practice. The development of culturally and linguistically appropriate, standardized picture corpora is a tedious and meticulous process. Yet, such readily accessible picture sets are useful for researchers and clinicians alike. The current study introduces a novel set of 269 verb pictures for an Indian language – Kannada. The included verbs were selected from a published database of 100,000 words along with their frequency scores in this language, and were subsequently categorized based on an argument structure taxonomy. Each picture is developed based on an exemplar sentence that depicts a scenario rather than a mere action. Norms are provided for verb name and argument agreement, image agreement, concept familiarity, and visual complexity, along with the orthographic frequency. Correlations between these measures are also described. The complete set of pictures are freely downloadable from https://osf.io/uk2af/?view_only=ecffbd92f48546a484c869b3f0b8ec94 for academic, research, and clinical usage in the future.
Highlights
Any standardized picture corpus is an essential tool for experimental linguistic research and clinical practice (Szekely et al, 2004)
A standardized picture corpus needs to be linguistically and culturally apposite to enhance its validity and rigor (Khwaileh et al, 2018), especially in a multilingual country like India, where the languages are radically different from foreign languages in terms of the sentence structure
In Kannada, the availability of a normative verb dataset based on the psychometric properties is sparse and remains as a much-needed resource
Summary
Any standardized picture corpus is an essential tool for experimental linguistic research and clinical practice (Szekely et al, 2004). The availability of a cross-culturally and crosslinguistically analogous stimulus sets is beneficial while assessing language comprehension and production (Khwaileh et al, 2018). Such standardized sets of stimuli can foster the designing of comprehensive assessment and therapeutic protocols. Pictures have been utilized as fundamental stimuli in psycholinguistic and neurolinguistic research. Experimenters and clinicians are forced to develop their own set of stimuli considering the linguistic and cultural differences,
