Three experiments examined the effects of word and phrase frequency on free recall. Word frequency did not affect word recall, but when participants studied and recalled lists of compositional adjective-noun phrases (e.g. alcoholic beverages ), phrase frequency had a consistently beneficial effect: both words from frequent phrases were more likely to be recalled than for infrequent phrases, providing evidence that long-term memory for phrases can aid in pattern completion, or redintegration. We explain these results and those of a previous study of phrase frequency effects in recognition memory (Jacobs, Dell, Benjamin, & Bannard , 2016) by assuming that the language processing system provides features that are linked to episodic contexts. Recall tasks map from these contexts to linguistic elements, and recognition maps from linguistic elements to contexts. Word and phrase frequency effects in both memory tasks emerge both within the language processing system and from multiple stored episodes, and the fact that the representations of phrases are tied to knowledge of their component words, rather than being representational islands.

Acoustic reduction for repeated words could be the result of articulation and motor practice (Lam & Watson, 2014), facilitated production (Gahl, Yao, & Johnson, 2012; Kahn & Arnold, 2015), or audience design and shared common ground (Galati & Brennan, 2010). We sought to narrow down what kind of facilitation leads to repetition reduction. Repetition could, in principle, facilitate production on a conceptual, lexical, phonological, articulatory, or acoustic level (Kahn & Arnold, 2015). We compared the durations of the second utterance of a target word when the initial production was aloud or silent. The silent presentation either involved unmouthed or mouthed inner speech. Overt production, unmouthed and mouthed inner speech all led to reduction in target word onsets, but target word durations were only shortened when a word was initially said aloud. In an additional experiment, we found that prior naming of a homophone of the target word also led to duration reduction. The results suggest that repetition reduction occurs when there is a recently experienced auditory memory of the item. We propose that duration may be controlled in part by auditory feedback during production, the use of which can be primed by recent auditory experience. [ABSTRACT FROM AUTHOR]

• Speakers slow down when producing similar-sounding words. • Speakers lengthen words when related words are heard or said. • The presence of potential competitors does not affect duration. • The absence of a competitor does not eliminate or reduce lengthening. Speakers tend to lengthen the durations of words when a phonologically overlapping word has recently been produced. Although there are multiple accounts of why lengthening occurs, all of these accounts generally assume that competition at some point in the production-comprehension process leads to lengthening. We investigated the contexts that lead to competition and consequent lengthening of target word duration. In three experiments, we manipulated the contexts in which a target word was produced. Speakers produced simple descriptions of animations involving referents that shared initial phonology with another potential referent (e.g., hat and hand). In Experiments 1 and 2, we manipulated whether the related referent (i.e. hat) was named by the speaker themselves, by another person, or was unmentioned. Experiment 2 additionally made speakers aware of competitors in the environment. In both experiments, we found that lengthening does not occur whenever there are two referents in the display that could be confused, even when it is clear that they are confusable. Instead, speakers only lengthened target words when the speaker or another person had named the phonologically related word out loud. Experiment 3 tested whether the task relevance of a phonological competitor influenced naming and found that speakers lengthen words that overlap with previously produced words, even when they were no longer competitors in the display. We propose that an auditory memory account best explains these results and discuss the implications of these findings for other accounts of lengthening. [ABSTRACT FROM AUTHOR]
