Asymetria mózgu i lateralizacja w jąkaniu

The diagnosis of developmental disorders – including those of speech fluency – have traditionally emphasized the meaning of atypical laterality. In the present paper we review briefly the literature showing that, even though stutter-ing, along with other language deficiencies, is indeed related to atypical brain asymmetry, the exact nature of this relation remains elusive, and the diagnostic utility of laterality measurement seems disputable.W diagnozie zaburzeń rozwojowych – w tym także zaburzeń płyn-ności mowy – tradycyjnie przywiązuje się dużą wagę do atypowej lateralizacji. Artykuł zawiera pobieżny przegląd literatury, pokazujący, że choć jąkanie, podob-nie jak inne zaburzenia sprawności językowej, faktycznie wiąże się z nietypową asymetrią mózgu, to natura tego związku pozostaje wciąż niejasna, a wartość diagnostyczna badania lateralizacji budzi wątpliwości.

Brain asymmetry, laterality and stuttering

Behavior assessment battery : normative and psychometric investigation among polish adults who do and do not stutter

Purpose: The aim of this study was to establish normative data for Polish persons who stutter (PWS) and persons who do not stutter (PWNS) with the adapted version of the Behavior Assessment Battery (BAB; Vanryckeghem & Brutten, 2018) for adults and to investigate whether or not gender and age influenced the results. In addition, the BAB subtests' reliability and validity were examined. Method: a Polish version of the BAB test procedures, ncluding the Speech Situation Checklist–Emotional Reaction, Speech Situation Checklist–Speech Disruption, Behavior Checklist, and Communication Attitude Test for Adults Who Stutter (Vanryckeghem & Brutten, 2018), were individually administered to 123 adults who stutter and 151 adults who do not stutter between the ages of 17 and 70. Results: PWS scored statistically significantly higher on all BAB subtests compared to PWNS. No significant between-groups gender or age difference was detected. The test data indicate high internal validity. The test items correlate well with the total score and significantly differentiate the two groups. The test battery validly differentiates PWS from PWNS with high accuracy. Conclusions: the Polish version of the BAB for adults confirms data collected in previous cross-cultural investigations. The results once again differentiate PWS from PWNS in a powerful way. Compared to PWNS, PWS report significantly more anxiety and speech breakdown when speaking in particular speech situations. They also report their attitude toward speech to be significantly more negative compared to the typical speaker and indicate using a significant number of coping behaviors to avoid or escape difficult speaking conditions. The BAB test battery, in its totality, assists in multidimensional assessment, pre- and posttreatment comparison, and identification of treatment targets based on the answers of PWS to each test item
