In order to grasp this established hypothesis in its entirety the current research, in a first step, builds theoretical foundations to explain a) the implications ofspeech production from visual stimuli for WM load, b) which elements of speech production that require WM resources are affected, and c) how semi-productive speech formulas operate so that also novel content can be packed into pre-fabricated form. Sports commentary provides excellent natural speech data to test the hypothesis, as it combines two different speech modes: 1) PLAY-BY-PLAY COMMENTARY -a highly WM resource demanding, time- pressured and activity-tied dual task of narrating the live events and 2) COLOR-COMMENTARY - non- activity-tied, unpressured free speech. More important, previous studies on sports commentary attest PLAY-BY-PLAY high formulaicity and COLOR-COMMENTARY almost none. A linguistic analysis of pausing, output quality and output rate as indicators of WM over- load in speech production for each mode is conducted in six transcriptions of live television coverage of basketball games. The results provide evidence that, despite the high WM resource demanding nature of play- by-play, the frequent use of semi-productive speech formulas allows play-by-play to show fewer characteristics of WM load in comparison to a) the color-commentary control data and b) language in experimental settings of speech production under increased WM load in the existing literature. Prä- fabrizierte Sprachformulae werden holistisch aus dem Langzeitgedächtnis abgerufen und schonen somit die Ressourcen des Arbeitsgedächtnisses (AG). Um diese Hypothese in ihrer Ganzheit zu verstehen wer- den vorerst theoretische Grundlagen erarbeitet, um a) die Auswirkungen einer Transformation visueller Stimuli in gesprochene Sprache auf das AG zu erklären, b) zu zeigen, wozu welche Elemente der Sprach- produktion AG-Ressourcen benötigen und c) wie semi-produktive Sprachformulae funktionieren, dass selbst neuer Inhalt in präfabrizierte Form gebracht werden kann. Sportkommentar ist eine exzellente Datenquelle natürlicher Sprache für die Überprüfung der Hypothese, da zwei unterschiedliche Sprach- modi kombiniert werden: 1) PLAY-BY-PLAY - Kommentieren der live Ereignisse unter Zeitdruck und 2) COLOR-COMMENTARY - nicht Ereignis gebundenes, freies Sprechen ohne Zeitdruck. Studien über Sportkommentar attestieren PLAY-BY-PLAY starke und COLOR- COMMENTARY praktisch keine For- mulaizität. Eine linguistische Analyse von Sprechpausen, Sprachqualität und -tempo als Indikatoren der Sprachproduktion unter erhöhter AG-Belastung in sechs Transkriptionen von TV-übertragenen Basket- ballspielen zeigt, dass PLAY-BY-PLAY, trotz seiner AG-Ressourcen beanspruchenden Natur, durch die häufige Verwendung von semi-produktiven Sprachformulae weniger Charakteristiken von AG-Belastung zeigt als a) die Vergleichsdaten des COLOR-COMMENTARY und b) die Sprache unter erhöhter AG- Belastung in Experimentalsituationen aus bestehender Literatur.
