Gender-inclusive language has evolved into a much-debated topic during the past years, discussed interdisciplinarily from theoretical to psycholinguistics, sociology, and economy – and by anyone who uses language.
Studies on German that primarily relied on questionnaires (reviewed in Braun et al. 2005), cloze tests (Klein 1988), and categorisation tasks with picture matching (Irmen & Köhncke 1996) disqualify the generically used masculine forms as pseudo-generic – failing their grammatically prescribed function to include referents of any Gender. Gender-balanced expressions (pair and split forms like Lehrer und Lehrerinnen) make explicit reference to female presence and participation, and thus elevate a more equitable interpretation.
Online methods to investigate the processing of Gender-sensitive language are surprisingly rare among research on the phenomenon, except for reaction time measures (Irmen & Köhncke 1996, Irmen & Kaczmarek 2000) and eye-tracking in reading (Irmen & Schumann 2011).
In addition, Gender-neutral language (GNL) has not been focused on in the majority of experiments, and when it was among the stimuli, results were inconclusive (De Backer & De Cuypere 2012) or found such alternatives to be ineffective (resembling masculine generics, Braun et al. 2005), despite the fact that guidelines on non-discriminatory language use commonly recommend these.
Gender-neutral (GN) expressions for personal reference in German include
• nominalised participles; nominalisations in general: Interessierte, Lehrende
• collective singulars: Publikum, Kollegium
• compounds (e.g., with a notion of “-person”): Ansprechpersonen, Lehrkräfte
• paraphrases that background a (gendered) subject: e.g., passives, relatives
In a visual world eye-tracking study, the comprehension of plural generics using masculine nouns and GN forms was tested for roles and occupations.
In complex stimulus scenarios, reference had to be established to referent images presented on a screen. At the end of each item, a question was asked in order to (re)identify the image that matched the referents of the respective setting best. Images depicted 1) a single person (protagonist), 2) an all-female group, 3) an all-male group, 4) a mixed Gender group of female and male members. The group referents were introduced with either a) masculine nouns (die Lehrer), b) female-specific feminine nouns (die Lehrerinnen), or c) one of the upper three nominal GN variants (die Lehrkräfte).
Results confirm the frequent male bias in masculine forms that are used as generics, that is, their male-specific interpretation. Furthermore, stereotypicality of nouns had an impact on responses. The GN alternatives, which are generally known to aim for indefinite reference (“marked” for Gender-fair language) were found to be most qualified to elicit mixed Gender group interpretations. When reference was established with GN terms, an inclusive response was consistently elicited. This was both indicated by eye movements and response proportions, but to a different extent depending on the particular GN noun type. Concepts that abstract from Gender in their linguistic forms (“neutralising” it) appear to be more inclusive, and thus better candidates for generic reference than masculines.
Most reading theories assume that readers aim at word centers for optimal information processing. During reading, saccade targeting turns out to be imprecise: Saccades’ initial landing positions often miss the word centers and have high variance, with an additional systematic error that is modulated by the distance from the launch site to the center of the target word. The performance of the oculomotor system, as reflected in the statistics of within-word landing positions, turns out to be very robust and mostly affected by the spatial information during reading. Hence, it is assumed that the saccade generation is highly automated.
The main goal of this thesis is to explore the performance of the oculomotor system under various reading conditions where orthographic information and the reading direction were manipulated. Additionally, the challenges in understanding the eye movement data to represent the oculomotor process during reading are addressed.
Two experimental studies and one simulation study were conducted for this thesis, which resulted in the following main findings:
(i) Reading texts with orthographic manipulations leads to specific changes in the eye movement patterns, both in temporal and spatial measures. The findings indicate that the oculomotor control of eye movements during reading is dependent on reading conditions (Chapter 2 & 3).
(ii) Saccades’ accuracy and precision can be simultaneously modulated under reversed reading condition, supporting the assumption that the random and systematic oculomotor errors are not independent. By assuming that readers increase the precision of sensory observation while maintaining the learned prior knowledge when reading direction was reversed, a process-oriented Bayesian model for saccade targeting can account for the simultaneous reduction of oculomotor errors (Chapter 2).
(iii) Plausible parameter values serving as proxies for the intended within-word landing positions can be estimated by using the maximum a posteriori estimator from Bayesian inference. Using the mean value of all observations as proxies is insufficient for studies focusing on the launch-site effect because the method exhibits the strongest bias when estimating the size of the effect. Mislocated fixations remain a challenge for the currently known estimation methods, especially when the systematic oculomotor error is large (Chapter 4).
The results reported in this thesis highlight the role of the oculomotor system, together with underlying cognitive processes, in eye movements during reading. The modulation of oculomotor control can be captured through a precise analysis of landing positions.
