Supplementary material for: Affective and Psycholinguistic Norms of Greek words: Manipulating their Affective or Psycho-linguistic Dimensions by Vaiouli P., Panteli M., Panayiotou G.

The present study presents a standardized database of 348 affective in the Greek language, including pleasant and unpleasant nouns and adjectives, and neutral adjectives in Greek language. The norms are based on the ratings made by 229 native Greek speaking young adults on affective (emotionality, valence, arousal, dominance) and psycho-linguistic dimensions (ambiguity, abstraction, imageability, familiarity) of the words. The words were selected and translated from four different sources, including the Affective Norms for English words (Bradley & Lang, 1999), the Affective Norms for Polish words (Imbir, 2015), the Norms of valence and arousal for English words (Warriner et al., 2013) and from the Greek lexicon of New Greek Language (Mpampiniotis, 2002). The participants assessed an average of 70 words through an online survey procedure. Results present the affective and psycholinguistic features of the words. Also, results provide associations between affective and psycholinguistic aspects of the word stimuli. Hence, the study produces insights on the effects of psycho-linguistic parameters of word stimuli on the affective ones and their interactions, by combining evaluations of valence and arousal and/or including ratings for affective and psycholinguistic dimensions of the words. As such, the current study offers a valuable resource that enables researchers working with Greek speaking populations to control or manipulate the affective or psycho-linguistic dimensions of words in different experimental paradigms, adjust them to specific experimental questions or issues of interest, and extract more accurate findings and conclusions. The newly developed database is freely available for researchers as supplementary material of this paper.
