Reversal shift in phonotactic learning during language production: Evidence for incremental learning
Publication date: June 2019Source: Journal of Memory and Language, Volume 106Author(s): Nathaniel D. Anderson, Eric W. Holmes, Gary S. Dell, Erica L. MiddletonAbstractSpeakers implicitly learn novel phonotactic patterns while producing strings of syllables. The learning is revealed in their speech errors. For example, if /f/ is artificially restricted to the syllable onset position and /s/ is restricted to the coda position, speakers’ slips will respect these constraints, demonstrating learning. The mechanism behind this learning was investigated by reversal shift. In two experiments, speakers produced syllable sequences for 32 trials in which one consonant was constrained to be an onset and one, a coda. Then for the next 32 trials, the constraints were reversed; for example, /f/ is now a coda and /s/ an onset. Over a third block of 32 trials, the constraints were reversed again back to the original rule. The learning of the reversed rules was slow in comparison to rapid learning of the original rule, providing evidence that the underlying mechanism is incremental. To learn a reversed rule, first one must unlearn the original association before making progress on the new rule. This pattern of rapid initial learning and slow reversal learning was replicated in a nonspeech analogue of the syllable production task. Participants pushed sequences of buttons, in which finger presses corresponded to consonants and thumb presses to vowels. A control experiment found that non-re...

It can be used asynchronously for interpretation of tests (spirometry, skin tests imaging studies), and for communication of information when the simultaneous presence of provider and patient is unnecessary. Synchronous encounters can be either unscheduled and initiated on-demand by patients or they can be facilitated substitutes for in-perso...

ConclusionOur data support the concept of MDH as a distinct and rare subgroup of DH. The prevalence in our database was 2.5% in the total DH alleged patient population and 0.5% of the demonstrated DH. Skin testing and DPT are mandatory for confirming the diagnosis.
ConclusionLong-term Abatacept therapy is effective in the majority of patients with LRBA deficiency.
ConclusionThus our results showed that higher IL-37 was associated with increased insulin sensitive in elderly type 2 DM patients through suppressing the gut microbiota dysbiosis.
