Use of context in question answering by 3-, 4- and 5-year-old children

This study investigates, within the theory of relevance of Sperber & Wilson (1995), how 3-, 4-, and 5-year-old children (n = 45) use context when answering questions. The children were required to answer questions that placed differing contextual and processing demands on them, as predicted by the theory. The results indicate that an increasing ability to use complex contextual information was related to age and was reflected in the children's ability to answer questions appropriately. A developmental pattern became evident in terms of how the children assigned referents, enriched semantic underdetermination, and recovered implicatures. It also became evident that even at the age of 5 years 6 months the children were in the process of becoming more skilled at integrating contextually complex inferences. It was further shown how children's selection of the appropriate context, given the focus of the question, depended on how relevance was achieved in that context.     

The epigenesis of stuttering

This paper examines the data on which the Demands and Capacities Model (DCM) is based with the purpose of identifying areas where future research might determine consilience among genetic influences at the physiological, behavioral, and cultural levels. The determination of consilience across different levels would tend to validate the genetic influence on stuttering, but more importantly it would also sharpen the focus of researchers interested in the various possible expressions that genetic influences might have and the way in which they influence the development of the disorder.

Educational objectives: The reader will (1) learn about the distinction, as outlined in the DCM, between environmental/contextual influences on stuttering development and intrinsic/genetic influences on stuttering development; (2) learn about the concept of consilience and its usefulness in conferring validity on parallel constructs at the physiological, behavioral, and cultural levels of stuttering theory; and (3) be able to identify potential areas for research that might help in refining our understanding of the genetic influences on stuttering development.     

Questioning Children Who May Have Been Sexually Abused

Summary

This article derives from an Open Forum on Leading Questions sponsored by the American Professional Society on the Abuse of Children. It represents the thoughts of participants in the Open Forum, and the article attempts to integrate analogue research that relates to questioning children about past events into questioning practice with children who may have been sexually abused. It proposes a continuum of questions that includes four categories: most preferred, preferred, less preferred, and least preferred.     

Syntactic Complexity Effects in Sentence Production

Syntactic complexity effects have been investigated extensively with respect to comprehension (e.g., Demberg & Keller, 2008; Gibson, 1998, 2000; Gordon et al., 2001, 2004; Grodner & Gibson, 2005; King & Just, 1991; Lewis & Vasishth, 2005; Lewis et al., 2006; McElree et al., 2003; Wanner & Maratsos, 1978). According to one prominent class of accounts (experience‐based accounts; e.g., Hale, 2001; Levy, 2008; Gennari & MacDonald, 2008, 2009; Wells et al., 2009), certain structures cause comprehension difficulty due to their scarcity in the language. But why are some structures less frequent than others? In two elicited‐production experiments we investigated syntactic complexity effects in relative clauses (Experiment 1) and wh‐questions (Experiment 2) varying in whether or not they contained non‐local dependencies. In both experiments, we found reliable durational differences between subject‐extracted structures (which only contain local dependencies) and object‐extracted structures (which contain nonlocal dependencies): Participants took longer to begin and produce object‐extractions. Furthermore, participants were more likely to be disfluent in the object‐extracted constructions. These results suggest that there is a cost associated with planning and uttering the more syntactically complex, object‐extracted structures, and that this cost manifests in the form of longer durations and disfluencies. Although the precise nature of this cost remains to be determined, these effects provide one plausible explanation for the relative rarity of object‐extractions: They are more costly to produce.     

Wolves in sheep’s clothing: How and when hypothetical questions influence behavior

How and when does responding to hypothetical questions shape future judgment and behavior? We identify knowledge accessibility as an implicit process through which hypothetical questions influence individuals, and examine moderators of accessibility that determine when these effects obtain. In an initial study, we show that hypothetical questions increase the accessibility of the specific positive or negative knowledge referenced by the question. In five subsequent studies, we manipulate factors known to enhance (consistency, elaboration) and attenuate (awareness, delay) accessibility, and show that these factors moderate the influence of hypothetical questions on individuals’ voting choices, legal decision-making, and consumption behavior.     

Summarizing information by means of causal sentences through causal graphs

The objective of this work is to propose a complete system able to extract causal sentences from a set of text documents, select the causal sentences contained, create a causal graph in base to a given concept using as source these causal sentences, and finally produce a text summary gathering all the information connected by means of this causal graph. This procedure has three main steps. The first one is focused in the extraction, filtering and selection of those causal sentences that could have relevant information for the system. The second one is focused on the composition of a suitable causal graph, removing redundant information and solving ambiguity problems. The third step is a procedure able to read the causal graph to compose a suitable answer to a proposed causal question by summarizing the information contained in it.     

Can propositional biases modulate syntactic repair processes? Insights from preceding comprehension questions

ABSTRACT

There is an ongoing debate about whether discourse biases can constrain sentence processing. Previous work has shown comprehension question accuracy to decrease for temporarily ambiguous sentences preceded by a context biasing towards an initial misinterpretation, suggesting a role of context for modulating comprehension. However, this creates limited modulation of reading times at the disambiguating word, suggesting initial syntactic processing may be unaffected by context [Christianson & Luke, 2011 Christianson, K. , & Luke, S. G. (2011). Context strengthens initial misinterpretations of text. Scientific Studies of Reading , 15 (2), 136–166. https://doi.org/ 10.1080/10888431003636787 [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. Context strengthens initial misinterpretations of text. Scientific Studies of Reading, 15(2), 136–166]. The current experiments examine whether propositional and structural content from preceding comprehension questions can cue readers to expect certain structures in temporarily ambiguous garden-path sentences. The central finding is that syntactic repair processes remain unaffected while reading times in other regions are modulated by preceding questions. This suggests that reading strategies can be superficially influenced by preceding comprehension questions without impacting the fidelity of ultimate (mis)representations.
