Long Eighteenth Century

The last two decades have seen the opening of several new paths in eighteenth-century musicology, and Robert O. Gjerdingen has opened one of these: schema theory. Schemata are ‘stock musical phrases employed in conventional sequences’ that function as harmonic, melodic and rhythmic frameworks for musical passages. Evidence of such schematic thinking has emerged through related studies on partimento and solfeggio. Solfeggio practice of the time manifests a schematic way of thinking about music, being mostly based on simple hexachordal patterns which, as studies progressed, could be embellished in different ways. Vasili Byros has addressed the ‘archaeology’ of hearing through reception history, and offered strong evidence that eighteenth-century ears did hear schemata. Interweaving corpus studies on music of the long eighteenth century (1720–1840), contemporary music criticism and reception history, as well as didactic documents from that era, Byros sheds new light on the ways in which schemata were perceived at the time. A recent contribution by Gilad Rabinovitch uses a live improvisation in the style of Mozart by Robert Levin to demonstrate the importance of conventional schemata for historical improvisation.

Abstract The theoretical debate on the nature of narrative has been mainly concerned with literary narratives, whereas forms of non-literary and especially pictorial narrativity have been somewhat neglected. In this paper, however, I shall discuss narrativity specifically with regard to pictorial objects in order to clarify how pictorial storytelling may be based on the activation of mentally stored action and scene schemas. Approaches from cognitive psychology, such as the work of Schank, Roger C. & Robert P. Abelson. 1977. Scripts, plans, goals and understanding. Hillsdale, NJ: Lawrence Erlbaum; Mandler, Jean Matter. 1984. Stories, scripts, and scenes: Aspects of schema theory. London/Hillsdale, NJ: Lawrence Erlbaum; Schank, Roger C. 1995. Tell me a story: Narrative and intelligence. Evanston, IL: Northwestern University Press, suggest that cognition crucially depends on the storage and retrieval of action scripts or schemata, that is, narrative structures, which may occur at various levels of abstraction. These schemas incorporate generalized knowledge about event sequences, such as the order in which specific events will take place; causal, enabling, or conventionalized relations between these events, and what kind of events occur in certain action sequences. There also are scene schemas that are characterized by spatial rather than temporal relations. Further kinds of schemas seem also to play a decisive role. Drawing upon considerations from schema and script theory, I will focus on some concrete examples of pictorial narration, more specifically depictions of the Annunciation of the Virgin Mary, where narrative schema structures become involved and, indeed, the comprehensibility of the pictures as such presuppose mental script representations.

This paper is the second part of a two-part paper which introduces a general schema theory for genetic programming (GP) with subtree-swapping crossover (Part I (Poli and McPhee, 2003)). Like other recent GP schema theory results, the theory gives an exact formulation (rather than a lower bound) for the expected number of instances of a schema at the next generation. The theory is based on a Cartesian node reference system, introduced in Part I, and on the notion of a variable-arity hyperschema, introduced here, which generalises previous definitions of a schema. The theory includes two main theorems describing the propagation of GP schemata: a microscopic and a macroscopic schema theorem. The microscopic version is applicable to crossover operators which replace a subtree in one parent with a subtree from the other parent to produce the offspring. Therefore, this theorem is applicable to Koza's GP crossover with and without uniform selection of the crossover points, as well as one-point crossover, size-fair crossover, strongly-typed GP crossover, context-preserving crossover and many others. The macroscopic version is applicable to crossover operators in which the probability of selecting any two crossover points in the parents depends only on the parents' size and shape. In the paper we provide examples, we show how the theory can be specialised to specific crossover operators and we illustrate how it can be used to derive other general results. These include an exact definition of effective fitness and a size-evolution equation for GP with subtree-swapping crossover.

This study was designed to examine the hands of unprimed constructs people use in an openended social perception task (Kelly Rep Test, Kelly, 1955). Three samples of subjects used their own natural categories or person schemes in judgments of familiar others. Results indicated that whereas the most prevalently used constructs with familiar others are best described as idiosyncratic, gender related trait sets of Agency and Communion were used widely by most subjects, with some individual differences associated with gender role. Masculine and Feminine subjects used constructs consistent with their own gender role (Agency and Communion, respectively) more than gender role inconsistent constructs (Communion and Agency, respectively), or constructs unrelated to gender Androgynous subjects were equally likely to use Agentic and Communal categories when describing others, and used gender-related categories overall more than Undifferential subjects. Results are discussed in relationship to gender schema and self-schema theory predictions.
