Lexical frequency effects on word accent processing in Swedish
(2016) Fonologi i Skandinavien- Abstract
- Lexical frequency effects on word accent processing in SwedishSeveral studies have investigated the neurophysiological underpinnings of the Swedish word accents, “accent 1” and “accent 2” ([1]-[5]), which are known to have a strong association with morphology ([6]-[8]). For example, if the singular noun suffix -en is attached to the word stem bil (‘car’), the resulting word is bil1-en (‘the car’) where the subscript indicates which word accent is attached. However, if the plural suffix -ar is attached to the stem, the word will be associated with accent 2 (bil2-ar, ‘cars’). The same is true for loan words: the word chatt ‘chat room’ takes accent 1 together with the singular suffix (chatt1-en) and accent 2 with the plural suffix... (More)

However, if the plural suffix -ar is attached to the stem, the word will be associated with accent 2 (bil2-ar, ‘cars’). The same is true for loan words: the word chatt ‘chat room’ takes accent 1 together with the singular suffix (chatt1-en) and accent 2 with the plural suffix (chatt2-ar). Furthermore, in Central Swedish, accent 2 is associated with compound words. Compounding is highly productive in Swedish, allowing the formation of novel compounds such as trädkrig2 (‘tree war’) or forskningsministerskola2 (‘research minister school’). Even if all constituents making up a compound would individually be accent 1 words, the compound will still have accent 2. For example, although neder1 ‘downwards’ and länderna1 ‘the lands’ are accent 1 words, the compound Nederländerna2 (‘the Netherlands’, example taken from [12]) has accent 2. What is interesting from the point of view of predictive models of language processing is that initial word stems with accent 2 (as opposed to stems with accent 1) could then potentially cue related accent 2 suffixes (e.g. plural, past tense) as well as a potentially infinite number of compounds. Investigations using the electroencephalography/event-related potentials (EEG/ERP) technique have found that words with accent 1 stems elicit larger ERP negativity effects as compared to accent 2 stems. This effect has previously been viewed as a positivity effect driven by accent 2’s prosodic salience ([1]). However, recent investigations have shown that accent 1 stems lead to increased neural activity, meaning that the ERP effect is more likely to be driven by some feature associated with accent 1 stems instead ([4]-[5]). We propose that the accent 1 stem negativity reflects a process by which upcoming suffixes are pre-activated by the word accent. Furthermore, evidence ([3]-[4]) now indicates that accent 1 stems pre-activate their associated suffixes more strongly than accent 2 stems. In the present contribution, we present results that suggest that the stem negativity is modulated by both the token and type frequency of lexical items that are possible continuations of a particular stem.ReferencesM.
