Exploring the longitudinal relationships between the use of grammar in text messaging and performance on grammatical tasks

Research has demonstrated that use of texting slang (textisms) when text messaging does not appear to impact negatively on children's literacy outcomes and may even benefit children's spelling attainment. However, less attention has been paid to the impact of text messaging on the development of children's and young people's understanding of grammar. This study therefore examined the interrelationships between children's and young adults’ tendency to make grammatical violations when texting and their performance on formal assessments of spoken and written grammatical understanding, orthographic processing and spelling ability over the course of 1 year. Zero‐order correlations showed patterns consistent with previous research on textism use and spelling, and there was no evidence of any negative associations between the development of the children's performance on the grammar tasks and their use of grammatical violations when texting. Adults’ tendency to use ungrammatical word forms (‘does you’) was positively related to performance on the test of written grammar. Grammatical violations were found to be positively associated with growth in spelling for secondary school children. However, not all forms of violation were observed to be consistently used in samples of text messages taken 12 months apart or were characteristic of typical text messages. The need to differentiate between genuine errors and deliberate violation of rules is discussed, as are the educational implications of these findings.     

Mystery,Values, and Meaning: Religious Options that Respect Science

Abstract

Human nature is a contested concept and notions of it vary across disciplines. Despite this diversity, three basic notions of human nature emerge. One identifies human nature with properties that are innate, hardwired or products of some kind of necessary essence. Another understands it as consisting of properties that make human unique or distinct from non-human animals. Finally, some seek human nature by attempting to identify universal or near-universal properties of humans. While the sciences might not give us a robust form of innate or hardwired human nature, “human nature” as a concept might still serve other, non-scientific, goals.     

Comparing emotional coordination in early spontaneous mother–infant and father–infant interactions

We compare matching of facial expressions and attunement of emotional intensity in spontaneous communication of mothers with infants and of fathers with infants, in families in Crete. Eleven infant–mother and 11 infant–father dyads were video-recorded at home in familiar interactions from the 2nd to the 6th month. Microanalysis of infant, maternal and paternal facial expressions of emotion provided evidence of quantitative differences that favour father–infant interaction as more playful, but the infants' behaviours with mothers and fathers show similar developmental curves. These results are discussed in the frame of the theory of innate intersubjectivity and of the emotional support parents give to developing motives of infants.     

Applying an exemplar model to the serial reaction-time task: Anticipating from experience

We present a serial reaction time (SRT) task in which participants identified the location of a target by pressing a key mapped to the location. The location of successive targets was determined by the rules of a grammar, and we varied the redundancy of the grammar. Increasing both practice and the redundancy of the grammar reduced response time, but the participants were unable to describe the grammar. Such results are usually discussed as examples of implicit learning. Instead, we treat performance in terms of retrieval from a multitrace memory. In our account, after each trial, participants store a trace comprising the current stimulus, the response associated with it, and the context provided by the immediately preceding response. When a target is presented, it is used as a prompt to retrieve the response mapped to it. As participants practise the task, the redundancy of the series helps point to the correct response and, thereby, speeds retrieval of the response. The model captured performance in the experiment and in classic SRT studies from the literature. Its success shows that the SRT task can be understood in terms of retrieval from memory without implying implicit learning.     

Learnability of embedded syntactic structures depends on prosodic cues

The ability to process center-embedded structures has been claimed to represent a core function of the language faculty. Recently, several studies have investigated the learning of center-embedded dependencies in artificial grammar settings. Yet some of the results seem to question the learnability of these structures in artificial grammar tasks. Here, we tested under which exposure conditions learning of center-embedded structures in an artificial grammar is possible. We used naturally spoken syllable sequences and varied the presence of prosodic cues. The results suggest that mere distributional information does not suffice for successful learning. Prosodic cues marking the boundaries of the major relevant units, however, can lead to learning success. Thus, our data are consistent with the hypothesis that center-embedded syntactic structures can be learned in artificial grammar tasks if language-like acoustic cues are provided.     

Explicit feedback maintains implicit knowledge

The role of feedback was investigated with respect to conscious and unconscious knowledge acquired during artificial grammar learning (AGL). After incidental learning of training sequences, participants classified further sequences in terms of grammaticality and reported their decision strategy with or without explicit veridical feedback. Sequences that disobeyed the learning structure conformed to an alternative structure. Feedback led to an increase in the amount of reported conscious knowledge of structure (derived rules and recollections) but did not increase its accuracy. Conversely, feedback maintained the accuracy of unconscious knowledge of structure (intuition or familiarity-based responses) which otherwise degraded. Results support a dual-process account of AGL. They suggest that implicit learning of the to-be-rejected structure at test contaminates familiarity-based classifications whereas feedback allows competing familiarity signals to be contextualised, which is incompatible with theories that consider familiarity context-insensitive.     

The relationship between strategic control and conscious structural knowledge in artificial grammar learning

We address Jacoby’s (1991) proposal that strategic control over knowledge requires conscious awareness of that knowledge. In a two-grammar artificial grammar learning experiment all participants were trained on two grammars, consisting of a regularity in letter sequences, while two other dimensions (colours and fonts) varied randomly. Strategic control was measured as the ability to selectively apply the grammars during classification. For each classification, participants also made a combined judgement of (a) decision strategy and (b) relevant stimulus dimension. Strategic control was found for all types of decision strategy, including trials where participants claimed to lack conscious structural knowledge. However, strong evidence of strategic control only occurred when participants knew or guessed that the letter dimension was relevant, suggesting that strategic control might be associated with – or even causally requires – global awareness of the nature of the rules even though it does not require detailed knowledge of their content.     

A rational analysis of rule-based concept learning

This article proposes a new model of human concept learning that provides a rational analysis of learning feature-based concepts. This model is built upon Bayesian inference for a grammatically structured hypothesis space—a concept language of logical rules. This article compares the model predictions to human generalization judgments in several well-known category learning experiments, and finds good agreement for both average and individual participant generalizations. This article further investigates judgments for a broad set of 7-feature concepts—a more natural setting in several ways—and again finds that the model explains human performance.     

汉语致使句的形式处理

There are at least five kinds of causative constructions in Chinese, the constructions of the collocation of verbs and prepositional phrases, verb-copying constructions, “ba” constructions with an object ahead, verb-copying constructions with their complements, and pivotal constructions with commands. But the current type-logical grammar has no tools representing the meanings of causative constructions. It would be neither intuitive nor simple to describe these constructions by means of the current type-logical grammar. So we intend to improve the type-logical grammar by adding CAUSE as a logical constant, complementing the structure rules about the movement and addition or deletion of some components of causative constructions, assigning categories to Chinese nouns and prepositions; then we give an intuitive as well as simple analysis on these causative constructions. Based on this work we shall extend the multimodal system of type-logical grammar, increase structure postulates, make constraints on frame semantics, and then prove the soundness and completeness of that system.      

What Kind of Normativity is the Normativity of Grammar?

The overall goal of this article is to show that aesthetics plays a major role in a debate at the very center of philosophy. Drawing on the work of David Bell, the article spells out how Kant and Wittgenstein use reflective judgment, epitomized by a judgment of beauty, as a key in their respective solutions to the rule‐following problem they share. The more specific goal is to offer a Kantian account of semantic normativity as understood by Wittgenstein. The article argues that Wittgenstein's reason for describing language as a collection of language games is to allow for a perspective that shows those games as internally purposive without any extralinguistic purpose. This perspective also allows for that union of the general rule and its particular application in practice that the original paradox of rule‐following is wanting.
