Relationships between language structure and language learning: the suffixing preference and grammatical categorization

It is a reasonable assumption that universal properties of natural languages are not accidental. They occur either because they are underwritten by genetic code, because they assist in language processing or language learning, or due to some combination of the two. In this paper we investigate one such language universal: the suffixing preference across the world's languages, whereby inflections tend to be added to the end of words. A corpus analysis of child-directed speech in English found that suffixes were more accurate at cuing the grammatical category of the root word than were prefixes. An artificial language experiment found that there was a learning advantage for suffixes over prefixes in terms of grammatical categorization within an artificial language. The results are consistent with an account of language universals that originate in general purpose learning mechanisms.     

J. Plateau: On the measurement of physical sensations and on the law which links the intensity of these sensations to the intensity of the source

Two papers published in 1872 by the Belgian physicist Plateau are here translated into English. The first paper contains the earliest published suggestion that the relation between physical stimulus magnitude and the strength of the internal sensation evoked is a power law and has been much cited for this reason. It also describes the earliest experiment to be performed, though not the first to be reported, on the subject of the psychophysical law. The performance of that experiment antedated Fechner'sElemente der Psychophysik by about 20 years. The second paper summarises a memoir in which a colleague, Delboeuf, reports his more extensive experiments on the subject and commends that memoir to the Belgian Royal Academy. In this second paper Plateau concludes that he was mistaken in supposing the psychophysical law to be a power relation.     

Specificity in the development of language structure

The nature of children's productive structures can be investigated via two types of structural error which are manifest in their surface data: the overextension of a very general adult rule to a context from which it is excluded, and the introduction of a novel rule in a specific context. Examples of these two types of errors are shown, on the one hand, to undermine theories which treat language development largely as a process of projecting and testing innately specified hypotheses; on the other hand, they provide support for more recent theories which conceive of abstract linguistic structure as the outcome of a process relating specifically acquired items and combinations of items. The implications of this conception for the goals and tasks of developmental psycholinguistics are explored.This paper is based on research undertaken for the Ph.D degree under the supervision of Dr. N. V. Smith, University College, London, and with the financial support of the Social Science Research Council of Great Britain.     

Improving perception of letters and visual structure of language.

Information about letters and the physical structure of language printed in Roman characters was given to children beginning to read. Experimental investigations coupled three alternative graphic modes of printing upper- and lower-case letters with an instructional intervention termed "Alpha-Beta" which provides practice in letter sorting, matching of letters, associative matching, and memory matching. In respect to graphics, Mode A letters were in standard alphabet form. Mode B provided standard letters with each backed by a unique half-tone (Visually Stippled Alphabet); Mode C provided standard letters with each backed by a unique visual texture (Visually Patterned Alphabet). Pre-posttest change in reading readiness was measured using the Metropolitan Readiness Test. In the first study 224 English-speaking 5- to 6-yr.-old children were tested. In the second there were 158 Spanish-speaking girls and boys 6 to 7 years old. It was predicted that Alpha-Beta intervention involving visually patterned alphabet would lead to the greatest increases in readiness scores. This is confirmed in both studies for children low in reading readiness preexperiment. Children high in reading readiness are less affected. The second experiment involved Spanish-speaking children and investigated intervention by Alpha-Beta against a no-intervention control. This confirms the value of Alpha-Beta per se. Possible explanations for the improvements are identified.     

A developmental grammar for syllable structure in the production of child language.

The order of acquisition of Dutch syllable types by first language learners is analyzed as following from an initial ranking and subsequent rerankings of constraints in an optimality theoretic grammar. Initially, structural constraints are all ranked above faithfulness constraints, leading to core syllable (CV) productions only. Subsequently, faithfulness gradually rises to the highest position in the ranking, allowing more and more marked syllable types to appear in production. Local conjunctions of Structural constraints allow for a more detailed analysis.     

Orthographic structure versus morphological structure: principles of lexical organization in a given language

Most models of visual word recognition in alphabetic orthographies assume that words are lexically organized according to orthographic similarity. Support for this is provided by form-priming experiments that demonstrate robust facilitation when primes and targets share similar sequences of letters. The authors examined form-orthographic priming effects in Hebrew, Arabic, and English. Hebrew and Arabic have an alphabetic writing system but a Semitic morphological structure. Hebrew morphemic units are composed of noncontiguous phonemic (and letter) sequences in a given word. Results demonstrate that form-priming effects in Hebrew or Arabic are unreliable, whereas morphological priming effects with minimal letter overlap are robust. Hebrew bilingual subjects, by contrast, showed robust form-priming effects with English material, suggesting that Semitic words are lexically organized by morphological rather than orthographic principles. The authors conclude that morphology can constrain lexical organization even in alphabetic orthographies and that visual processing of words is first determined by morphological characteristics.     

Intention, interpretation and the computational structure of language

I show how a conversational process that takes simple, intuitively meaningful steps may be understood as a sophisticated computation that derives the richly detailed, complex representations implicit in our knowledge of language. To develop the account, I argue that natural language is structured in a way that lets us formalize grammatical knowledge precisely in terms of rich primitives of interpretation. Primitives of interpretation can be correctly viewed intentionally, as explanations of our choices of linguistic actions; the model therefore fits our intuitions about meaning in conversation. Nevertheless, interpretations for complex utterances can be built from these primitives by simple operations of grammatical derivation. In bridging analyses of meaning at semantic and symbol-processing levels, this account underscores the fundamental place for computation in the cognitive science of language use.     

Thoughts and sensations,twin galaxies of the inner space: The propensity to mind-wander relates to spontaneous sensations arising on the hands

Sensations and thoughts have been described as potentially related to self-awareness. We therefore asked whether sensations that arise in the absence of external triggers, i.e., spontaneous sensations (SPS), which were shown to relate to interoception and perception of the self, vary as a function of the individual propensity to generate spontaneous thoughts, i.e., mind-wandering. The Mind Wandering Questionnaire (MWQ) was used as a specific tool to assess the frequency and propensity to mind-wander several weeks before completing an SPS task. Correlational analyses between the MWQ score and SPS showed that greater propensity to mind-wander coincided with widespread perception of SPS, while lesser propensity to mind-wander coincided with more spatially restricted perception of SPS. The results are interpreted in light of the role of spontaneous thoughts and sensations in self-awareness. The potential psychological processes and the way they might regulate the relation between mind-wandering and the perception of SPS are discussed.     

Investigating the mechanisms of visually-evoked tactile sensations

When attempting to detect a near-threshold signal, participants often incorrectly report the presence of a signal, particularly when a stimulus in a different modality is presented. Here we investigated the effect of prior experience of bimodal visuotactile stimuli on the rate of falsely reported touches in the presence of a light. In Experiment 1, participants made more false alarms in light-present than light-absent trials, despite having no experience of the experimental visuotactile pairing. This suggests that light-evoked false alarms are a consequence of an existing association, rather than one learned during the experiment. In Experiment 2, we sought to manipulate the strength of the association through prior training, using supra-threshold tactile stimuli that were given a high or low association with the light. Both groups still exhibited an increased number of false alarms during light-present trials, however, the low association group made significantly fewer false alarms across conditions, and there was no corresponding group difference in the number of tactile stimuli correctly identified. Thus, while training did not affect the boosting of the tactile signal by the visual stimulus, the low association training affected perceptual decision-making more generally, leading to a lower number of illusory touch reports, independent of the light.     

Syntactic component in language responsible cognitive structure: Neurological evidence

From the results of a broad ranging comprehension test, a hierarchy of difficulty emerged that is shared by the two groups of aphasics (Broca's and Wernicke's aphasics) and by the control group of normal subjects. The parallelism has been interpreted as a confirmation of the hypothesis that syntactic competence is not inaccessible either in Wernicke's or in Broca's aphasia. The Minimal Distance Principle, as a relevant recognition principle, has been studied, and although not confirmed by the scores has been brought to the fore both by the correlations between the variables under study and by the correlations with the concomitant variables of age and level of education.     

Within-person changes in the structure of emotion: the role of cultural identification and language

This study explored the within-person dynamic organization of emotion in East-Asian Canadian bicultural individuals as they function in two cultural worlds. Using a diary design, we examined under what conditions their emotional structure resembles that of Westerners or that of East Asians. As predicted, when these bicultural individuals identified with a Western culture or had recently spoken a non-Asian language, their positive and negative affect were inversely associated. When they identified with an Asian culture or interacted in an Asian language, this inverse association disappeared. This study shows that as bicultural individuals identify and communicate with members of one or the other cultural group, they may adopt a culturally congruent phenomenology, including a distinct affective pattern.     

Argument structure and the child's contribution to language learning

One of the oldest questions in cognitive science asks whether children are able to learn language (or anything) because they are equipped with a very powerful general-purpose learning mechanism or because they are equipped with a domain-specific constrained language acquisition device. Recent advances in statistical approaches to language learning seem to boost the plausibility of general-purpose learning. However, in this article we propose that in the domain of verb learning, children rely more on their internally generated preconceptions about linguistic structure than on robust cues in the input, suggesting that at least in this aspect of language learning, domain-specific grammatical knowledge guides linguistic development.     

Testing the factor structure of the beliefs about language learning inventory

This preliminary study examined the factor structure of the Beliefs About Language Learning Inventory in two samples of about 750 college students of English as a foreign language in Taiwan. Results of confirmatory factor analysis lend partial support to Horwitz's theoretical five-factor belief model. Subsequent exploratory and confirmatory factor analyses of data show that a four-factor model represented by only 12 items performed better than other models both theoretically and empirically. This model consists of two dimensions already theorized in the inventory: Difficulty of Language Learning and Foreign Language Aptitude, and two newly interpreted dimensions, Importance of Spoken Language and Analytical Approaches to Language Learning. Although this four-factor model could be replicated in an independent sample, the factors are not reliable, suggesting the need to search for a more representative set of beliefs to tap specific aspects of language learning.     

From adorable to worthless: implicit and self‐report structure of highly evaluative personality descriptors

So‐called highly ‘evaluative’ personality judgments (e.g. describing someone as exceptional, odd, or vile,) are an integral component of people's daily judgments of themselves and others. However, little is known about the conceptual structure, psychological function, and personality‐relevance of these kinds of attribution. Two studies were conducted to explore the internal (i.e. implicit) and external (i.e. self‐report) structure of highly evaluative terms. Factor analyses of semantic‐similarity sortings and self‐reports on several representative samples of highly evaluative personality adjectives yielded internal and external structures that were very similar. Both types of structure included five dimensions representing distinction, worthlessness, depravity, unconventionality, and stupidity. The robustness of the uncovered dimensions across the two studies suggests that typically excluded highly evaluative personality terms, far from being behaviorally ambiguous and psychologically uninformative, allude to meaningful dispositions that people both implicitly understand and possess to different degrees. These findings also suggest that highly evaluative personality judgments are organized around the basic domains of morality (i.e. depravity), power (distinction and worthlessness), peculiarity (unconventionality), and intelligence (stupidity). We discuss the implications of our findings for the study of self‐ and other‐esteem processes, personality perception, and the Big Seven factor model of personality.
