Learning Word Meanings: Overnight Integration and Study Modality Effects

According to the complementary learning systems (CLS) account of word learning, novel words are rapidly acquired (learning system 1), but slowly integrated into the mental lexicon (learning system 2). This two-step learning process has been shown to apply to novel word forms. In this study, we investigated whether novel word meanings are also gradually integrated after acquisition by measuring the extent to which newly learned words were able to prime semantically related words at two different time points. In addition, we investigated whether modality at study modulates this integration process. Sixty-four adult participants studied novel words together with written or spoken definitions. These words did not prime semantically related words directly following study, but did so after a 24-hour delay. This significant increase in the magnitude of the priming effect suggests that semantic integration occurs over time. Overall, words that were studied with a written definition showed larger priming effects, suggesting greater integration for the written study modality. Although the process of integration, reflected as an increase in the priming effect over time, did not significantly differ between study modalities, words studied with a written definition showed the most prominent positive effect after a 24-hour delay. Our data suggest that semantic integration requires time, and that studying in written format benefits semantic integration more than studying in spoken format. These findings are discussed in light of the CLS theory of word learning.     

Collapse of The System of Word Meanings In Aphasia

1. Data obtained from an investigation of the speech of aphasics confirm the view of linguists that the meaning of a word represents a definite system. Thus, in a word of multiple meanings we distinguish the "nucleus," which comprises free, nominative meanings that are coextensive with the objective reference of the word, and the "periphery," comprising the contextual, associative meanings.     

The Biosemiotic Glossary Project: Umwelt

This is the second article in a series of review articles addressing biosemiotic terminology. The biosemiotic glossary project is designed to integrate views of members within the biosemiotic community based on a standard survey and related publications. The methodology section describes the format of the survey conducted July–August 2014 in preparation of the current review and targeted on Jakob von Uexküll’s term ‘Umwelt’. Next, we summarize denotation, synonyms and antonyms, with special emphasis on the denotation of this term in current biosemiotic usage. The survey findings include ratings of eight citations defining or making use of the term Umwelt. We provide a summary of respondents’ own definitions and suggested term usage. Further sections address etymology, relevant contexts of use, and related terms in English and other languages. A section on the notion’s Uexküllian meaning and later biosemiotic meaning is followed by attempt at synthesis and conclusion. We conclude that the Umwelt is a centerpiece phenomenon, a phenomenon that other phenomena in the living realm are organized around. To sum up Uexküll’s view, we can characterize an Umwelt as the subjective world of an organism, enveloping a perceptual world and an effector world, which is always part of the organism itself and a key component of nature, which is held together by functional cycles connecting different Umwelten. In order to pay respect to Uexküll’s work, we must move from notion to model, from mention of Uexküll’s Umwelt term to actual application of it.

The Biosemiotic Glossary Project: Intentionality

In 2014, Morten Tønnessen and the editors of Biosemiotics officially launched the Biosemiotic Glossary Project in the effort to: (1) solidify and detail established terminology being used in the field of Biosemiotics for the benefit of newcomers and outsiders; and to (2) by involving the entire biosemiotics community, to contribute innovatively in the theoretical development of biosemiotic theory and vocabulary via the discussions that result. Biosemiotics, in its concern with explaining the emergence of, and the relations between, both biological ‘end-directedness’ and semiotic ‘about-ness’, would seem a fertile field for re-conceptualizing the notion of intentionality. The present project is part of a systematic attempt to survey and to document the current thinking about this concept in our field.     

Human Origins Studies: A Historical Perspective

Research into the deep history of the human species is a relatively young science which can be divided into two broad periods. The first spans the century between the publication of Darwin’s Origin and the end of World War II. This period is characterized by the recovery of the first non-modern human fossils and subsequent attempts at reconstructing family trees as visual representations of the transition from ape to human. The second period, from 1945 to the present, is marked by a dramatic upsurge in the quantity of research, with a concomitant increase in specialization. During this time, emphasis shifted from classification of fossil humans to paleoecology in which hominids were seen as parts of complex evolving ecosystems. This shift is in no small part due to the incorporation of neo-Darwinian synthetic theory. Finally, technological innovation and changes in social context are considered as influences on human origins studies.
