"Near" and "far" in language and perception.

A major interest in cognitive science is the relationship between linguistic and perceptual representations of space. One approach to exploring this relationship has been to investigate aspects of the linguistic encoding of space that correspond closely to aspects of the visual system. Another approach, which does not contradict the first but rather complements it, is to investigate ways in which linguistic and visual representations of space are different. This paper pursues the second approach by arguing that the distinction between proximal and distal demonstratives (e.g. this vs. that, here vs. there) does not correspond to an independently established distinction between near and far space in the visual system but is instead based on language-internal factors. Recent neuropsychological and neurophysiological studies suggest that the brain contains separate mechanisms for representing, on the one hand, near or peripersonal space which extends roughly to the perimeter of arm's reach and, on the other hand, far or extrapersonal space which expands outward from that boundary. In addition, crosslinguistic research suggests that it is very common for languages to have two basic types of demonstrative terms - proximal and distal. This parallelism raises the possibility that the linguistic distinction may derive from the perceptual distinction. However, several arguments support the contrary view that the two distinctions are independent of one another. A substantial proportion of languages in the world have demonstrative systems that divide space into three or more egocentrically-grounded regions, thereby violating the two-way perceptual contrast. Even more importantly, empirical studies of how demonstratives are used in ongoing discourse in different languages suggest that they do not encode quantitative spatial information such as within vs. beyond arm's reach; instead, they specify abstract semantic notions that, when combined with the unique pragmatic features of communicative contexts, allow speakers to make a virtually unlimited range of spatial distance contrasts. Thus, demonstratives constitute an interesting case of divergence between linguistic and perceptual representations of space.     

Primary or "specific" language impairment and children learning a second language

We review empirical findings from children with primary or "specific" language impairment (PLI) and children who learn a single language from birth (L1) and a second language (L2) beginning in childhood. The PLI profile is presented in terms of both language and nonlinguistic features. The discussion of L2 learners emphasizes variable patterns of growth and skill distribution in L1 and L2 which complicate the identification of PLI in linguistically diverse learners. We then introduce our research program, designed to map out common ground and potential fault lines between typically developing children learning one or two languages, as compared to children with PLI.     

Psychology and "ordinary language"—a critique of Smedslund

This article takes up methodological issues of the kind raised by Jan Smedslund in earlier issues of this journal, concerning the status of psychological enquiry as a discipline. Arguments are presented which aim to show that Smedslund has failed to establish the thesis that all generally valid theoretical statements in psychology are explications of conceptual relationships embedded in ordinary language, i.e., analytic statements. Some specific examples of what Smedslund takes to be "ordinary language theorems" are examined. Doubts are expressed concerning the validity of the proof procedure Smedslund employs in the "demonstration" of a number of his alleged theorems. Finally, it is argued that the results produced by the situation-bound and culture-bound empirical research of the psychologist need not be viewed as "arbitrary" in Smedslund's sense of that term.     

"Long before short" preference in the production of a head-final language

A tendency for speakers to produce short phrases before long phrases has been attributed to the accessibility of short phrases, and thought to reflect universal mechanisms of production. However, recent corpus analyses in Japanese suggest that long phrases tend to be shifted ahead of short ones (Hawkins, J. (1994). A performance theory of order and constituency. Cambridge: Cambridge University Press; Yamashita, in press). Two on-line experiments confirmed that speakers shifted long arguments to earlier positions more than short arguments, exhibiting a "long before short" preference. We reconcile these contradictory data from English and Japanese by a competition between different factors in an incremental production system.     

A critique of Mark D. Allen's "the preservation of verb subcategory knowledge in a spoken language comprehension deficit"

Allen [Allen, M. (2005). The preservation of verb subcategory knowledge in a spoken language comprehension deficit. Brain and Language, 95, 255-264.] reports a single patient, WBN, who, during spoken language comprehension, is still able to access some of the syntactic properties of verbs despite being unable to access some of their semantic properties. Allen claims that these findings challenge linguistic theories which assume that much of the syntactic behavior of verbs can be predicted from their meanings. I argue, however, that this conclusion is not supported by the data for two reasons: first, Allen focuses on aspects of verb syntax that are not claimed to be influenced by verb semantics; and second, he ignores aspects of verb syntax that are claimed to be influenced by verb semantics.     

"Capacity" reconsidered: interindividual differences in language comprehension and individual alpha frequency

The influence of interindividual differences in cognitive mechanisms on language comprehension remains controversial not only due to conflicting experimental findings, but also in view of the difficulty associated with determining which measure should be used in participant classification. Here, we address the latter problem by proposing that an electrophysiological measure, individual alpha frequency (IAF), may be a suitable means of classifying interindividual differences in sentence processing. Interindividual differences in IAF have been shown to correlate with performance on memory tasks and speed of information processing. In two experiments using event-related brain potentials (ERPs), IAF-based participant groups differed systematically with regard to the processing of ambiguous sentences such that the low-IAF group showed a sustained positivity in the ambiguous region, while the high-IAF group did not. These interindividual differences were independent of whether the ambiguity was syntactic (Experiment 1) or sentence-level semantic (Experiment 2). Moreover, they were reliable only when participants were classified according to IAF, but not in classifications based on reading span, speed of processing (reaction time), or accuracy of processing (error rate).     

"A picture's worth a thousand words": language use in the autophotographic essay

The authors applied Pennebaker's Linguistic Inquiry and Word Count (LIWC) program to autophotographic essays addressing the question, "Who are you?" to test hypotheses about individuality and social connectedness. Specifically, the authors tested whether insight-oriented words would correlate with individuality ratings, defining essays that portray unique persons who creatively explore the self. Second, the authors tested whether connectedness, operationalized by photos of people-touching and self with others, would correlate with social process words. In 164 student photo essays, greater linguistic cognitive complexity characterized individuality, even when controlling for needs for cognition and uniqueness, and verbal intelligence. Connectedness predicted social words. These findings show that autophotography essays do capture complex self-reflective thought and suggest LIWC may be a valuable tool for understanding the expression of individuality and relatedness.     

Kohonen neural networks and language.

Kohonen neural networks are a type of self-organizing network that recognizes the statistical characteristics of input datasets. The application of this type of neural network to language theory is demonstrated in the present note by showing three brief applications: recognizing word borders, learning the limited phonemes of one's native tongue, and category-specific naming impairments.     

Perceiving the language of films.

Children appear to be familiar with the language of film makers or at least to perceive and remember films less well when the rules of this cinematic language are broken. In this experiment a simple action sequence filmed from a static viewpoint was made up into two films of four shots. One film was edited according to the rules of directional continuity specified by Hollywood cinema, that is the four shots were presented so as to preserve the subject's direction of movement across cuts. The other film was edited disregarding these rules. Apart from this difference both films were identical. Children aged seven, nine, and thirteen years watched either of these films and reconstructed the action using pictures representing the four shots. The children who saw the conventional version were better able to reconstruct what they had seen than those who saw the unconventional version.     

Euthanasia and John Paul II's "silent language of profound sharing of affection:" why Christians should care about Peter Singer.

Peter Singer's recent appointment to Princeton University created considerable controversy, most of it focused on his proposal for active euthanasia of disabled infants. Singer articulates utilitarian ideas that often appear in public discussions of euthanasia. Drawing on Pope John Paul II's work on ethics and suffering, I argue that Singer's utilitarian theory of value is impoverished. After introducing the Pope's ethic based on the imago dei, I discuss love as self-gift. I show how this concept supports a theory of value in which spiritual goods are preeminent over material goods. I then describe how suffering reveals spiritual goods, discussing how participation in Christ's suffering can alter our perception of value. I also consider how communal responses to suffering provide opportunities for self-giving. Third, I consider Singer's proposal for killing infants with hemophilia, arguing that it arbitrarily ignores spiritual goods. I then discuss proposals to kill anencephalic infants, discussing how parental responses to their suffering can demonstrate an extraordinary love in seemingly hopeless circumstances. I conclude by calling for a more sustained social response to euthanasia initiatives.
