Complexity dips in random infinite binary sequences

Given any function f with σn=0∞ 2−f(n) divergent, it is shown that every finite binary sequence x has an infinite number of initial segments, xn, with K(xn) ⩽ n − f(n)

Auditoryâ motor adaptation is reduced in adults who stutter but not in children who stutter

Previous studies have shown that adults who stutter produce smaller corrective motor responses to compensate for unexpected auditory perturbations in comparison to adults who do not stutter, suggesting that stuttering may be associated with deficits in integration of auditory feedback for online speech monitoring. In this study, we examined whether stuttering is also associated with deficiencies in integrating and using discrepancies between expected and received auditory feedback to adaptively update motor programs for accurate speech production. Using a sensorimotor adaptation paradigm, we measured adaptive speech responses to auditory formant frequency perturbations in adults and children who stutter and their matched nonstuttering controls. We found that the magnitude of the speech adaptive response for children who stutter did not differ from that of fluent children. However, the adaptation magnitude of adults who stutter in response to auditory perturbation was significantly smaller than the adaptation magnitude of adults who do not stutter. Together these results indicate that stuttering is associated with deficits in integrating discrepancies between predicted and received auditory feedback to calibrate the speech production system in adults but not children. This auditoryâ motor integration deficit thus appears to be a compensatory effect that develops over years of stuttering.We examined auditoryâ motor adaptation in children and adults who stutter.

Partial Compensation in Speech Adaptation

We propose that speech planning is driven by targets which incorporate both auditory and somatosensory feedback. In three experiments, we show that (1) talkers compensate for abnormal auditory feedback, (2) compensation is more complete for small shifts in feedback than for large shifts in feedback, and (3) the completeness of compensation is driven by the discrepancy between auditory and somatosensory feedback

Brain regions underlying repetition and auditory-verbal short-term memory deficits in aphasia: Evidence from voxel-based lesion system mapping

The goal of this study was to identify the neural correlates of repetition and a related process, auditory-verbal short-term memory (AVSTM). Both repetition and 15 AVSTM involve common elements such as auditory and phonological analysis and translation to speech output processes. Based on previous studies, we predicted that both repetition and AVSTM would be most dependent on posterior language regions in left temporo-parietal cortex
