Orienting versus learning instructions in children's free recall: New evidence

Ninety-six first graders were given a list of either words or pictures to process under three types of incidental orienting instructions (semantic, directed at list organization; semantic, directed at individual item characteristics; and physical) and an intentional-learning instruction. For pictures and words, list organizational instructions were the most effective, and were superior to intentional-learning instructions. In contrast, individual item-orienting instructions were not better than intentional-learning instructions on either list. Additionally, different patterns of instructional effects emerged on the two list types, which were interpreted with respect to both available data and contemporary processing theories.     

Understanding and appreciating metaphors

We consider three theories that have dominated discussions of metaphor. One view is that metaphors make comparisons, the basis for the comparison being the features (or categories) that the terms of the metaphor share. The second view is that metaphors involve an anomaly. The third view is that metaphors are ‘interactive’, producing a new way of seeing the terms. We propose a new theory—the domains-interaction view—that draws on elements of all three earlier views, but borrows especially from the interaction view. We consider the implications of our theory for three questions: What are metaphors? How are they understood? What makes a good metaphor? We argue that metaphors correlate two systems of concepts from different domains. The best metaphors involve two diverse domains (more distance between domains making for better metaphors) and close correspondence between the terms within those domains. We call the degree of correspondence within-domain similarity. Metaphors are interpreted in several stages: the terms of the metaphor are encoded; the domains involved are inferred; the structures to be seen as parallel are found; the correspondences between these structures are ‘mapped’ or constructed; the terms of the metaphor are compared. If the terms are not seen to match or occupy analogous roles in their different domains, then the metaphor may be reinterpreted. The evidence on all this is tentative but supports our view. We review two studies (Tourangeau and Sternberg, 1981) that support the hypothesis that distance within domain relates negatively to aptness, whereas distance between domains relates positively. Several studies on comprehension tend to disconfirm the comparison theory's notion that the tenor and vehicle necessarily share features. Tenor and vehicle also appear to have asymmetrical roles in the interpretive process.     

Functional constraints on sentence processing: A cross-linguistic study

English and Italian provide some interesting contrasts that are relevant to a controversial problem in psycholinguistics: the boundary between grammatical and extra-grammatical knowledge in sentence processing. Although both are SVO word order languages without case inflections to indicate basic grammatical relations, Italian permits far more variation in word order for pragmatic purposes. Hence Italians must rely more than English listeners on factors other than word order. In this experiment, Italian and English adults were asked to interpret 81 simple sentences varying word order, animacy contrasts between the two nouns, topicalization and contrastive stress. Italians relied primarily on semantic strategies while the English listeners relied on word order—including a tendency to interpret the second noun as subject in non-canonical word orders (corresponding to word order variations in informal English production). Italians also made greater use of topic and stress information. Finally, Italians were much slower and less consistent in the application of word order strategies even for reversible NVN sentences where there was no conflict between order and semantics. This suggests that Italian is ‘less’ of an SVO language than English. Semantic strategies apparently stand at the ‘core’ of Italian to the same extent that word order stands at the ‘core’ of English. It is suggested that these results pose problems for claims about a ‘universal’ separation between semantics and syntax, and for theories that postulate a ‘universal’ priority of one type of information over another. Results are discussed in the light of the competition model, a functionalist approach to grammar that accounts in a principled way for probabilistic outcomes and differential ‘weights’ among competing and converging sources of information in sentence processing.     

The acquisition of prenominal modifier sequences

This paper presents a study of children's interpretations of prenominal modifier sequences like the one in ‘the second green ball’. In such phrases the modifier ‘second’ has scope over the rest of the phrase. It is shown that children misinterpret these phrases in such a way that it appears that they give ‘second’ scope only over the head noun of the phrase. A series of six experiments, all designed to test various hypotheses about the motivating factors behind this misinterpretation is described. Experiments 1 and 2 constitute a replication and extension of the work in this area originally done by Roeper (1972). Experiment 3 tests a set of hypotheses about the influence of certain syntactic variables in conditioning the children's misinterpretations. Experiment 4 is an attempt to check an hypothesis about the semantic complexity of phrases like ‘the second green ball’. Experiments 5 and 6 test the children's sensitivity to ordering constraints in different kinds of prenominal modifier sequences. The results are presented in Section 3 and discussed in Section 4. It is argued that the children's misinterpretations of the phrases come about because of their tendency to be conservative about the amount of hierarchically organized structure they will postulate in the absence of evidence that such structure is needed.     

Blowing in the wind: Perceiving structure in trees and bushes

When lights are mounted at the ends of the limbs of a tree and the surround darkened such that branches and trunk are not visible, viewers can nonetheless make systematic and precise judgments about the unseen structure of the tree through its motion. They seem to perform this task by picking up information about the relative arborization of the tree through the vector paths of the lights on the limbs. Theoretically speaking, the focus of this study is on the perception of second-order centers of moment; previous studies have focused on the perception of first-order centers. A second-order center in a tree-like structure is the location where limb meets trunk, and it is these that perceivers can infer from the dynamic display. The importance of this study is to demonstrate further that the study of centers of moment makes possible a detailed and differential study of event perception.     

Reading and listening comprehension in Broca's aphasia: Lexical versus syntactical errors

Ten agrammatic Broca's aphasics were presented with a series of four picture plates together with a spoken or written sentence stimulus. All sentence stimuli were of the structure, the + N + is/are + V + ing + the + N. The four pictures on each stimulus plate represented (a) the correct response, (b) a reversal of the stimulus sentence subject and object, (c) a change in the number of the subject of the stimulus sentence, and (d) a change in one of the major lexical items of the stimulus sentence. Subjects selected the correct picture most often. When they erred, they usually selected a subject-object reversal. Number errors were less frequent, and the patients seldom selected a change in major lexical item. This pattern occurred with both written and spoken sentences. These results were interpreted as reflecting the dependence of agrammatic Broca's aphasics on the semantic interpretation of the lexicon for decoding sentences in the face of deficits in syntactical-grammatical interpretation, irrespective of comprehension modality.     

A watched pot sometimes boils: a study of duration experience

The ‘watched pot’ phenomenon — the lengthening of duration experience when one is attentively and perhaps impatiently waiting for some event to occur — was studied in three experiments. In them, each observer attended for a duration of 270 sec to a liquid-containing beaker on an electrical burner. Observers who were told that the experiment concerned time perception (prospective paradigm) reproduced the duration as longer than those told that it concerned visual perception (retrospective paradigm). In the prospective paradigm, reproductions were longer if the liquid did not boil than if it did, and an interruption (task-unrelated questioning) shortened reproductions if the liquid did not boil but had no effect if it did. In the retrospective paradigm, if there was boiling or questioning or both, reproductions were longer than if there was neither. Results have implications for hypotheses about duration experience.
