  abstract  = {Fixational eye movements occur involuntarily during visual fixation of stationary scenes. The fastest components of these miniature eye movements are microsaccades, which can be observed about once per second. Recent studies demonstrated that microsaccades are linked to covert shifts of visual attention [e.g., Engbert \& Kliegl (2003), Vision Res 43:1035-1045]. Here,we generalized this finding in two ways. First, we used peripheral cues, rather than the centrally presented cues of earlier studies. Second, we spatially cued attention in vision and audition to visual and auditory targets. An analysis of microsaccade responses revealed an equivalent impact of visual and auditory cues on microsaccade-rate signature (i.e., an initial inhibition followed by an overshoot and a final return to the pre-cue baseline rate). With visual cues or visual targets,microsaccades were briefly aligned with cue direction and then opposite to cue direction during the overshoot epoch, probably as a result of an inhibition of an automatic saccade to the peripheral cue. With left auditory cues and auditory targets microsaccades oriented in cue direction. Thus, microsaccades can be used to study crossmodal integration of sensory information and to map the time course of saccade preparation during covert shifts of visual and auditory attention.},

  abstract  = {The predictability of an upcoming word has been found to be a useful predictor in eye movement research, but is expensive to collect and subjective in nature. It would be desirable to have other predictors that are easier to collect and objective in nature if these predictors were capable of capturing the information stored in predictability. This paper contributes to this discussion by testing a possible predictor: conditional co-occurrence probability. This measure is a simple statistical representation of the relatedness of the current word to its context, based only on word co-occurrence patterns in data taken from the Internet. In the regression analyses, conditional co-occurrence probability acts like lexical frequency in predicting fixation durations, and its addition does not greatly improve the model fits. We conclude that readers do not seem to use the information contained within conditional co-occurrence probability during reading for meaning, and that similar simple measures of semantic relatedness are unlikely to be able to replace predictability as a predictor for fixation durations. Keywords: Co-occurrence probability, Cloze predictability, frequency, eye movement, fixation duration.},

  abstract  = {Previous studies on the relation between language and social cognition have shown that children's mastery of embedded sentential complements plays a causal role for the development of a Theory of Mind (ToM). Children start to succeed on complementation tasks in which they are required to report the content of an embedded clause in the second half of the fourth year. Traditional ToM tasks test the child's ability to predict that a person who is holding a false belief (FB) about a situation will act "falsely". In these task, children do not represent FBs until the age of 4 years. According the linguistic determinism hypothesis, only the unique syntax of complement sentences provides the format for representing FBs. However, experiments measuring children's looking behavior instead of their explicit predictions provided evidence that already 2-year olds possess an implicit ToM. This dissertation examined the question of whether there is an interrelation also between implicit ToM and the comprehension of complement sentences in typically developing German preschoolers. Two studies were conducted. In a correlational study (Study 1 ), 3-year-old children's performance on a traditional (explicit) FB task, on an implicit FB task and on language tasks measuring children's comprehension of tensed sentential complements were collected and tested for their interdependence. Eye-tracking methodology was used to assess implicit ToM by measuring participants' spontaneous anticipatory eye movements while they were watching FB movies. Two central findings emerged. First, predictive looking (implicit ToM) was not correlated with complement mastery, although both measures were associated with explicit FB task performance. This pattern of results suggests that explicit, but not implicit ToM is language dependent. Second, as a group, 3-year-olds did not display implicit FB understanding. That is, previous findings on a precocious reasoning ability could not be replicated. This indicates that the characteristics of predictive looking tasks play a role for the elicitation of implicit FB understanding as the current task was completely nonverbal and as complex as traditional FB tasks. Study 2 took a methodological approach by investigating whether children display an earlier comprehension of sentential complements when using the same means of measurement as used in experimental tasks tapping implicit ToM, namely anticipatory looking. Two experiments were conducted. 3-year-olds were confronted either with a complement sentence expressing the protagonist's FB (Exp. 1) or with a complex sentence expressing the protagonist's belief without giving any information about the truth/ falsity of the belief (Exp. 2). Afterwards, their expectations about the protagonist's future behavior were measured. Overall, implicit measures reveal no considerably earlier understanding of sentential complementation. Whereas 3-year-olds did not display a comprehension of complex sentences if these embedded a false proposition, children from 3;9 years on were proficient in processing complement sentences if the truth value of the embedded proposition could not be evaluated. This pattern of results suggests that (1) the linguistic expression of a person's FB does not elicit implicit FB understanding and that (2) the assessment of the purely syntactic understanding of complement sentences is affected by competing reality information. In conclusion, this dissertation found no evidence that the implicit ToM is related to the comprehension of sentential complementation. The findings suggest that implicit ToM might be based on nonlinguistic processes. Results are discussed in the light of recently proposed dual-process models that assume two cognitive mechanisms that account for different levels of ToM task performance.},

  abstract  = {The incremental nature of sentence processing raises questions about the way the information of incoming functional elements is accessed and subsequently employed in building the syntactic structure which sustains interpretation processes. The present work approaches these questions by investigating the negative particle ne used for sentential negation in Bulgarian and its impact on the overt realisation and the interpretation of imperative inflexion, bound aspectual morphemes and clitic pronouns in child, adult and aphasic language. In contrast to other Slavic languages, Bulgarian negative imperatives (NI) are grammatical only with imperfective verbs. We argue that NI are instantiations of overt aspectual coercion induced by the presence of negation as a temporally sensitive sentential operator. The scope relation between imperative mood, negation, and aspect yields the configuration of the imperfective present which in Bulgarian has to be overtly expressed and prompts the imperfective marking of the predicate. The regular and transparent application of the imperfectivising mechanism relates to the organisation of the TAM categories in Bulgarian which not only promotes the representation of fine perspective shifts but also provides for their distinct morphological expression. Using an elicitation task with NI, we investigated the way 3- and 4-year-old children represent negation in deontic contexts as reflected in their use of aspectually appropriate predicates. Our findings suggest that children are sensitive to the imperfectivity requirement in NI from early on. The imperfectivisation strategies reveal some differences from the target morphological realisation. The relatively low production of target imperfectivised prefixed verbs cannot be explained with morphological processing deficits, but rather indicates that up to the age of five children experience difficulties to apply a progressive view point to accomplishments. Two self-paced reading studies present evidence that neurologically unimpaired Bulgarian speakers profit from the syntactic and prosodic properties of negation during online sentence comprehension. The imperfectivity requirement negation imposes on the predicate speeds up lexical access to imperfective verbs. Similarly, clitic pronouns are more accessible after negation due to the phono-syntactic properties of clitic clusters. As the experimental stimuli do not provide external discourse referents, personal pronouns are parsed as object agreement markers. Without subsequent resolution, personal pronouns appear to be less resource demanding than reflexive clitics. This finding is indicative of the syntax-driven co-reference establishment processes triggered through the lexical specification of reflexive clitics. The results obtained from Bulgarian Broca's aphasics show that they exhibit processing patterns similar to those of the control group. Notwithstanding their slow processing speed, the agrammatic group showed no impairment of negation as reflected by their sensitivity to the aspectual requirements of NI, and to the prosodic constraints on clitic placement. The aphasics were able to parse the structural dependency between mood, negation and aspect as functional categories and to represent it morphologically. The prolonged reaction times (RT) elicited by prefixed verbs indicate increasing processing costs due to the semantic integration of prefixes as perfectivity markers into an overall imperfective construal. This inference is supported by the slower RT to reflexive clitics, which undergo a structurally triggered resolution. Evaluated against cross-linguistic findings, the obtained result strongly suggests that aphasic performance with pronouns depends on the interpretation efforts associated with co-reference establishment and varies due to availability of discourse referents. The investigation of normal and agrammatic processing of Bulgarian NI presents support for the hypothesis that the comprehension deficits in Broca's aphasia result from a slowed-down implementation of syntactic operations. The protracted structure building consumes processing resources and causes temporal mismatches with other processes sustaining sentence comprehension. The investigation of the way Bulgarian children and aphasic speakers process NI reveals that both groups are highly sensitive to the imperfective constraint on the aspectual construal imposed by the presence of negation. The imperfective interpretation requires access to morphologically complex verb forms which contain aspectual morphemes with conflicting semantic information - perfective prefixes and imperfective suffixes. Across modalities, both populations exhibit difficulties in processing prefixed imperfectivised verbs which as predicates of negative imperative sentences reflect the inner perspective the speaker and the addressee need to take towards a potentially bounded situation description.},

Three eye-movement data sets based on the reading of Dutch and German unrelated sentences reveal a sizeable, replicable increase in reading times over several words in the beginning and the end of sentences. The data from the paragraphbased English-language Dundee corpus replicate the pattern and also indicate that the increase in inspection times is driven by the visual boundaries of the text organized in lines, rather than by syntactic sentence boundaries. We argue that this effect is independent of several established lexical, contextual and oculomotor predictors of eye-movement behavior. We also provide evidence that the effect of word position-intext has two independent components: a start-up effect arguably caused by a strategic oculomotor program of saccade planning over the line of text, and a wrap-up effect originating in cognitive processes of comprehension and semantic integration.},

  abstract  = {During reading oculomotor processes guide the eyes over the text. The visual information recorded is accessed, evaluated and processed. Only by retrieving the meaning of a word from the long-term memory, as well as through the connection and storage of the information about each individual word, is it possible to access the semantic meaning of a sentence. Therefore memory, and here in particular working memory, plays a pivotal role in the basic processes of reading. The following dissertation investigates to what extent different demands on memory and memory capacity have an effect on eye movement behavior while reading. The frequently used paradigm of the reading span task, in which test subjects read and evaluate individual sentences, was used for the experimental review of the research questions. The results speak for the fact that working memory processes have a direct effect on various eye movement measurements. Thus a high working memory load, for example, reduced the perceptual span while reading. The lower the individual working memory capacity of the reader was, the stronger was the influence of the working memory load on the processing of the sentence.},
