SEMANTIC SATIATION FOR POETIC EFFECT

This article argues that the defamiliarization caused by extensive repetition, termed ‘semantic satiation’ in psychology, was used by ancient poets for specific effects. Five categories of repetition are identified. First, words undergo auditory deformation through syllable and sound repetition, as commonly in ancient etymologies. Second, a tradition of emphatic proper-name repetition is identified, in which the final instance of the name is given special emphasis; this tradition spans Greek and Latin poetry, and ultimately goes back to the Nireus entry in the Catalogue of Ships. Third, repetition is used for wordplay, where the final instance of the repeated term not only is emphasized but also incurs some change to its meaning or shape. Fourth, the incantatory repetition of divine names in hymns and cultic invocations amplifies a sense of divine presence behind and beyond the repetend. Fifth, repetition of half and full lines by different speakers in Old Comedy serves to undercut and parody the original sense of the repeated words. Extensive repetition in ancient literature was never merely ornamental but was used for a range of specific auditory and semantic effects with distinct and identifiable structures.

Late Night Thoughts on Listening to Schoenberg’s Klavierstück, op. 33a

This essay considers the sound of Arnold Schoenberg’s Klavierstück, op. 33a, discussing aesthetic effects of combinatoriality and pitch repetition. In taking John Rahn’s general advice regarding listening to Schoenberg “late at night with the lights off,” two compelling parallels with psycholinguistic phenomena emerge—one dealing with semantic satiation, and the other with a related experience called the verbal transformation effect.

Gender Word Semantic Satiation Inhibits Facial Gender Information Processing

In order to explore the time course of the influence of gender words semantic satiation on facial gender information processing, the semantic satiation paradigm was used to induce semantic satiation by presenting Chinese gender words “男, 女 (Male, Female)” for a long duration (25 s), with conjunction words “及(And), 且(Moreover)” served as the baseline (the Chinese words and their English translations do not completely equal in terms of pronunciation, form, and sense). Participants were asked to judge whether the two simultaneously presented faces (Experiment 1) or two successively presented faces (Experiment 2) were of the same gender. The results of Experiment 1 showed that the response time in semantic satiation condition was significantly longer than that of the baseline condition. The event-related potential (ERP) results of Experiment 2 showed that the peak amplitude of P1 component in semantic satiation condition was significantly smaller than that of the baseline condition in the early stage of face processing; N170, a specific component of face perception, in semantic satiation condition was significantly larger than that of the baseline condition. The average amplitude of LPC in semantic satiation condition was significantly smaller than that of the baseline condition. This study shows that facial gender information processing is affected by its semantic contextual information. The inhibition effect of gender word semantic satiation on facial gender information processing starts at the attention orientation stage, then continues to the face structural encoding stage, and eventually ends at the advanced cognitive response stage.

When comprehension elicits incomprehension: Deterioration of semantic categorisation in the absence of stimulus repetition

Repetition improves retrieval from memory; however, under some circumstances, it can also impair performance. Separate literatures have investigated this phenomenon, including studies showing subjective loss of meaning following ‘semantic satiation’, slowed naming and categorisation when semantically related items are repeated and semantic ‘access deficits’ in aphasia. Such effects have been variously explained in terms of habituation of repeatedly accessed representations, increased interference from strongly activated competitors and long-term weight changes reflecting the suppression of non-targets on earlier trials (i.e., retrieval-induced forgetting). While studies of semantic satiation involve massed repetition of individual items, competition and weight changes at the conceptual level should elicit declining comprehension for non-repeated items: this pattern has been demonstrated for picture naming but effects in categorisation are less clear. We developed a paced serial semantic task (PSST), in which participants identified category members among distracters. Performance in healthy young adults deteriorated with ongoing retrieval for non-repeated words belonging to functional categories (e.g., picnic), taxonomic categories (e.g., animal) and feature-based categories (e.g., colour red – ‘tomato’, ‘post box’). This decline was greatest at fast presentation speeds (when there was less time to overcome competition/inhibition) and for strongly associated targets (which may have accrued more inhibition to facilitate earlier target categorisation). Deteriorating performance was also seen across words and pictures, consistent with a conceptual locus. We observed a release from deteriorating categorisation following a switch to a new category, demonstrating that this was not a general effect of time on task. Patients with semantic aphasia, who have deficient semantic control, maintained their performance throughout the categories, unlike younger adults: this finding is hard to reconcile with accounts of declining performance that propose a build-up of competition, since the patients should have had greater difficulty resolving such competition. These results instead suggest that declining performance on our goal-driven categorisation task was linked to the use of a controlled retrieval strategy by healthy young adults. Patients may not have inhibited related non-target knowledge to facilitate initial categorisation like younger volunteers, and consequently they were less vulnerable to declining comprehension in this paradigm. Together, these results demonstrate circumstances which produce declines in continuous categorisation in healthy adults.
