In this study we asked whether nonwords created by transposing two phonemes (/biksɔt/) are perceived as being more similar to their base words (/biskɔt/) than nonwords created by substituting two phonemes (/bipfɔt/). Using the short-term phonological priming and a lexical-decision task, Experiment 1 showed that transposed-phoneme nonword primes lead to shorter RTs on the target base words than substituted-phoneme nonword primes. Using a single-presentation lexical-decision task, Experiment 2 showed that transposed-phoneme nonwords lead to longer "no" decision responses than substituted-phoneme nonwords. In both Experiments 1 and 2, the transposed-phoneme effect was observed when the transposed phonemes were adjacent (/biksɔt/-/biskɔt/) but not when they were distant (/ʃoloka/-/ʃokola/). Our findings suggest that nonwords created by transposing adjacent phonemes in real words generate more activation of the lexical representations associated with the base words than do matched control nonwords. More generally, our findings present a challenge for models of spoken word recognition that code for the precise order of speech segments.

Let them eat ceke: An electrophysiological study of form-based prediction in rich naturalistic contexts.

It is well-established that people make predictions during language comprehension--the nature and specificity of these predictions, however, remain unclear. For example, do comprehenders routinely make predictions about which words (and phonological forms) might come next in a conversation, or do they simply make broad predictions about the gist of the unfolding context? Prior EEG studies using tightly controlled experimental designs have shown that form-based prediction can occur during comprehension, as N400s to unexpected words are reduced when they resemble the form of a predicted word (e.g.

Purpose: The purpose of this study was to describe the speech production, speech perception, vocabulary, and word learning abilities of lexically precocious 4-year-old children with phonological impairment, in an effort to better understand the underlying nature of phonological impairment in children.
Method: Using a case series approach, we identified four children with phonological impairment and precocious vocabulary abilities. Each child completed routine speech production and vocabulary assessments, as well as experimental speech perception and word learning tasks.

Studies of letter transposition effects in alphabetic scripts provide compelling evidence that letter position is encoded flexibly during reading, potentially during an early, perceptual stage of visual word recognition. Recent studies additionally suggest similar flexibility in the spatial encoding of syllabic information in the Korean Hangul script. With the present research, we conducted two experiments to investigate the locus of this syllabic transposition effect.

Listeners can use prior knowledge to predict the content of noisy speech signals, enhancing perception. However, this process can also elicit misperceptions. For the first time, we employed a prime-probe paradigm and transcranial magnetic stimulation to investigate causal roles for the left and right posterior superior temporal gyri (pSTG) in the perception and misperception of degraded speech.
