Description
Statistical word learning (SWL) has been proposed and tested as a powerful mechanism for word learning under referential ambiguity. Learners are adept at resolving word-referent ambiguity by calculating the co-occurrences between words and referents across ambiguous scenes. Despite the generalizability of such capacity, it is less clear which underlying factors may play a role in SWL, such as learners’ language experience and individual differences of working memory. The current study therefore asked two questions: 1) How do learners of different language experience (monolinguals and bilinguals) approach SWL of different mapping types–when each referent has one name (1:1 mapping) or two names (2:1 mapping)? and 2) How do working memory capacities (spatial and phonological) play a role in SWL by mapping type? In this pre-registered study (OSF: https://osf.io/mte8s/), 69 English monolinguals and 88 bilinguals completed two SWL tasks (1:1 and 2:1 mapping), a symmetry span task indexing spatial working memory, and a listening span task indexing phonological working memory. Results showed no differences between monolinguals and bilinguals in SWL of both mapping types. However, spatial and phonological working memory positively predicted SWL regardless of language experience, but only in 1:1 mapping. The findings show a dissociation of working memory’s role in SWL of different mapping types. The study proposes a novel insight into a theoretical debate underlying statistical learning mechanisms: learners may adopt more explicit processes (i.e. hypothesis-testing) during 1:1 mapping but implicit processes (i.e. associative learning) during 2:1 mapping. Future studies can locate memory-related brain areas during SWL to test out the proposal.

The Wham-Womb Sound Symbolic Effect: English-Speaking Children and Adults Link Phonemes with Arousal
Description
Sound symbolism—the association between word sounds and meaning—has been shown to be an effective communication tool that promotes language comprehension and word learning. Much of the literature is constrained to investigating sound as it relates to physical characteristics (e.g. size or shape), and research has predominantly studied the phenomenon in adults. The current study examined the sound symbolic wham-womb effect, which postulates that words with the /æ/ phoneme are associated with increased arousal while words with the /u/ phoneme are associated with little to no arousal. The effect was tested in both adults and children aged 5-7 years old using a word-to-scene matching task. Participants were presented with two pseudowords (differing only by their vowel phoneme: /æ/ or /u/; e.g. smad and smood) and two scenes depicting an animal in either a more arousing or less arousing situation. Participants were then asked to match which of the scenes fit one of the pseudowords. Results showed that the trial-by-trial performance for adults and children were significantly greater than chance, indicating that the wham-womb effect is exhibited in both adults and children. There was also a significant difference in performance between adults and children, with adults showing a more robust effect. This study provides the first empirical evidence that both children and adults link phonemes to arousal and that this effect may change across development.

Description
The label-feedback hypothesis (Lupyan, 2007, 2012) proposes that language modulates low- and high-level visual processing, such as priming visual object perception. Lupyan and Swingley (2012) found that repeating target names facilitates visual search, reducing response times and increasing accuracy. Hebert, Goldinger, and Walenchok (under review) used a modified design to replicate and extend this finding, and concluded that speaking modulates visual search via template integrity. The current series of experiments 1) replicated the work of Hebert et al. with audio stimuli played through headphones instead of self-directed speech, 2) examined the label feedback effect under conditions of varying object clarity, and 3) explored whether the relative prevalence of a target’s audio label might modulate the label feedback effect (as in the low prevalence effect; Wolfe, Horowitz, & Kenner, 2005). Paradigms utilized both traditional spatial visual search and repeated serial visual presentation (RSVP). Results substantiated those found in previous studies—hearing target names improved performance, even (and sometimes especially) when conditions were difficult or noisy, and the relative prevalence of a target’s audio label strongly impacted its perception. The mechanisms of the label feedback effect––namely, priming and target template integrity––are explored.
