The Minho Word Pool: Norms for imageability, concreteness, and subjective frequency for 3,800 Portuguese words

Abstract

Words are widely used as stimuli in cognitive research. Because of their complexity, using words requires strict control of their objective (lexical and sublexical) and subjective properties. In this work, we present the Minho Word Pool (MWP), a dataset that provides normative values of imageability, concreteness, and subjective frequency for 3,800 (European) Portuguese words-three subjective measures that, in spite of being used extensively in research, have been scarce for Portuguese. Data were collected with 2,357 college students who were native speakers of European Portuguese. The participants rated 100 words drawn randomly from the full set for each of the three subjective indices, using a Web survey procedure (via a URL link). Analyses comparing the MWP ratings with those obtained for the same words from other national and international databases showed that the MWP norms are reliable and valid, thus providing researchers with a useful tool to support research in all neuroscientific areas using verbal stimuli. The MWP norms can be downloaded along with this article or from http://p-pal.di. uminho.pt/about/databases.

Learning to read facilitates the retrieval of phonological representations in rapid automatized naming: Evidence from unschooled illiterate, ex‐illiterate, and schooled literate adults

“…Line drawings of 20 objects were selected from the MPI database according to the 2 Word‐form frequency (high vs. low) × 2 Phonological neighborhood density (dense vs. sparse) of objects' names. The four experimental conditions differed on frequency of occurrence ( M : 42 vs. 3 per million for high‐frequency vs. low‐frequency; SUBTLEX‐PT database; Soares et al, ) and neighborhood density ( M : 8.3 vs. 1.5 neighbors for dense vs. sparse neighborhoods; P‐PAL: Soares, Costa, Machado, Comesaña, & Oliveira, ). They were matched ( t tests, all p s > 0.12) in orthographic and phonological length, orthographic neighborhood density (Soares et al, ), neighbors' frequency, and on pictures' visual complexity (Szekely & Bates, ).…”

Imageability and subjective frequency of the 500 rated nouns in the Croatian Lexical Database

“…Subjective word frequency is an estimation of the number of times a word is encountered by an individual, be it in spoken or written form (Balota, Pilotti & Cortese, 2001;Soares et al, 2017). The term frequency effect claims that subjects respond more rapidly and more accurately to higher-frequency words than to lower-frequency words in tasks of lexical decision (Whaley, 1978;Grainger, 1990), and that speed naming by healthy adults and adults with aphasia is higher for higher-frequency words than for lower-frequency words (Forster & Chambers, 1973;Kay & Ellis, 1987;Grainger, 1990;Kittredge et al, 2008).…”

“…word class, phonological and morphological complexity, orthographic similarity) and usage-related (e.g. frequency of use, age of acquisition, familiarity) (Lind et al, 2015;Soares et al, 2017). Some of these properties are measured objectively, others subjectively, and still others (e.g.…”

Psycholinguistic estimates of 3000 words of Croatian: concreteness and imageability

“…Sli~na baza izra|ena je i za nizozemski (Brysbaert et al 2014a). Baza za portugalski (Soares et al 2017) sadr`ava 3.800 rije~i i premda, ~ini se, sadr`ava podatke za razli~ite vrste rije~i, razlike me|u njima nisu navedene u istra`ivanju. Baze za druge jezike razli~itih su veli~ina i ~esto sadr`avaju samo jednu vrstu rije~i, npr.…”
