This study aims to account for the variation in aspect choices in factual imperfective contexts in Polish, Czech, and Russian. A series of online questionnaires were conducted wherein the native speakers of the tested languages were asked to fill in the missing verbs for two types of existential contexts (neutral and resultative) and four types of presuppositional factual contexts (weakly and strongly resultative with a focus on the initiator or the result state of the past event). We show that neutral existential factual contexts generally elicited significantly more imperfective choices than resultative existential factual contexts. Additionally, there was a trend towards a higher usage of imperfective in weakly resultative presuppositional contexts as compared to strongly resultative presuppositional contexts, suggesting that the less emphasis is placed on the result state the more likely the choice of imperfective aspect is for the expression of the temporal indefiniteness of factual contexts. Russian showed a significantly higher proportion of imperfective uses than Polish and Czech, with Czech being intermediate. We argue that these observations result from the fact that in all types of factual contexts (both existential and presuppositional) there is an interaction between two types of TEMPORAL (IN)DEFINITENESS of the past event: (i) temporal (in)definiteness at the micro-level (first phase syntax-vP) (depending on the position of the time variable within the temporal event of the past complex event) and (ii) (in)definiteness of the past event at the macro-level (second phase syntax–AspP and TP) (related to the position of the past event relative to the utterance time). We show that both discourse-level information and verb-level information interact in determining these two types of (in)definiteness, and they do it differently in Polish, Czech, and Russian.

This paper offers new insights into the status of secondary imperfective morphology and its interaction with different classes of aspectual affixes based on the analysis of their compatibility with basic perfective and basic imperfective VP idioms in Polish. We provide new evidence in favor of the vP-external status of secondary imperfective morphology and we propose a new architecture of aspectual morphology in Polish in which there are two classes of vP-external superlexical prefixes: high and low. The former are projected in several functional projections above secondary imperfective morphology while the latter are projected below it in a single dedicated functional projection.

This study contributes to a longstanding discussion on the status of aspectual morphology and the aspectual architecture in Slavic by investigating aspectual properties of perfective and imperfective VP idioms in Polish. The investigation reveals that only lexical prefixes which can result in idiosyncratic meanings are part of basic perfective VP idioms. Building on the idea that littlevis a demarcation line for idiomatic meanings, it is concluded that lexical prefixes arevP-internal. It is also shown that basic imperfective VP idioms are compatible with some superlexical prefixes and basic perfective VP idioms are compatible with secondary imperfective morphology, which suggests that such morphology isvP-external. Further semantic analysis of the interaction of basic imperfective VP idioms with different classes of superlexical prefixes shows that the compatible ones measure over some scale associated withvP-external material or the temporal trace of an (idiomatic) event. In contrast, the incompatible ones measure over a scale encoded by a verbal predicate or impose semantic restrictions on its argument and hence they intervene in the semantics of a VP idiom. Based on stacking facts and the interaction of different classes of superlexical prefixes with secondary imperfective morphology, two classes of superlexical prefixes are distinguished:high(projected above secondary imperfective) andlow(projected below it). These observations are compatible with the view that aspectual morphology is separated from PFV and IPFV operators. The former may merge lower in the hierarchy, and the latter act at the level of AspP as phonologically null operators.

Eye-tracking methods have become a valuable tool for reading research, as they provide significant evidence on the behavioral and cognitive performance of developing readers. They also help identify reading behavior patterns among children with neurodevelopmental conditions, such as reading difficulties (RD) or attention-deficit hyperactivity disorder (ADHD). In this paper, we reviewed relevant literature (73 empirical studies) from 2008 to 2023 (15 years). We documented how reading performance was measured through eye-tracking methodology among typical and atypical readers across various languages. To ensure a rigorous and transparent review, we adhered to the PRISMA framework, defined keywords, established inclusion and exclusion criteria, conducted data extraction, and employed a multi-phase selection process. We focused on research samples, stimulus designs, independent variables, eye-tracking systems, and metrics. The results indicated that research involving typically developing children mainly included participants from primary school and employed various eye-tracking methods, with English being the most studied language. Studies on children with RD and ADHD varied significantly in participants’ sample sizes, languages, and experimental designs. The discussion emphasizes the need for standardized data-collection procedures to enhance the reliability and comparability of findings, thereby supporting the development of effective interventions and instructional methods for reading difficulties.

The article is a contribution to a long-standing discussion on how idioms are represented and accessed in the mental lexicon. More specifically, in a timed cloze response study we investigate high and low syntactic flexibility idioms in Polish in order to find out whether the degree of syntactic flexibility influences the ease and time of idioms’ recognition. By doing so we contribute to the question of whether idioms are differently represented in the lexicon depending on their syntactic flexibility, as suggested by Nunberg et al. 1994 and Gibbs and Nayak 1989, or whether all idioms independent of their syntactic flexibility are represented lexically in the same hybrid way, as suggested by Cutting and Bock 1997 and Sprenger et al. 2006. The results of our study support the latter view.

This study aims to account for the microvariation in aspect choices in factual imperfective contexts in Polish. To this goal an online questionnaire was conducted in which the participants from western and eastern Poland were asked to fill in the missing verbs in presuppositional and existential factual contexts involving an Elaboration coherence relation. The study shows that perfective aspect is preferred in presuppositional factual contexts and imperfective is preferred in existential factual contexts in both regions. Additionally, imperfective is generally more often used in factual contexts in eastern Poland than in western Poland. The study accounts for the observed preferences by resorting to the interaction between the Elaboration relation and (in)definiteness of the temporal variable (introduced at the level of AspP) with respect to the temporal trace of a complex event decomposed in the first phase syntax.
