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.     

Automatic access of the meanings of ambiguous words in context: Some limitations of knowledge-based processing

Five experiments are described on the processing of ambiguous words in sentences. Two classes of ambiguous words (noun-noun and noun-verb) and two types of context (priming and nonpriming) were investigated using a variable stimulus onset asynchrony (SOA) priming paradigm. Noun-noun ambiguities have two semantically unrelated readings that are nouns (e.g., PEN, ORGAN); noun-verb ambiguities have both noun and verb readings that are unrelated (e.g., TIRE, WATCH). Priming contexts contain a word highly semantically or associatively related to one meaning of the ambiguous word; nonpriming contexts favor one meaning of the word through other types of information (e.g., syntactic or pragmatic). In nonpriming contexts, subjects consistently access multiple meanings of words and select one reading within 200 msec. Lexical priming differentially affects the processing of subsequent noun-noun and noun-verb ambiguities, yielding selective access of meaning only in the former case. The results suggest that meaning access is an automatic process which is unaffected by knowledge-based (“top-down”) processing. Whether selective or multiple access of meaning is observed largely depends on the structure of the ambiguous word, not the nature of the context.     

Word frequency and children's stuttering: The relationship to sentence structure

This study investigated the relationship between word-frequency level and stuttering within the context of four slected sentence types. Fifteen stuttering children, aged 8–12, read 48 sentences of four different transformational types, and three word-frequency levels 12 simple active-affirmative-declarative (SAAD), 12 negative, 12 passive and 12 negative-passive. All sentences were identical in terms of underlying swings and variations of the SAAD sentences. Results agreed with Ronson's study with adults (1976) in that when the group rating was severe and the sentence type was negative, stuttering increased significantly as word-frequency level decreased. It appears that children's stuttering in relationship to word-frequency level is a different response that is subject to variables of sentence type and the severity rating of stuttering.     

Attributed influence: The importance of observing change

The presence of a target's unexpected change in behavior following an influence attempt was hypothesized to be a critical variable for attributing influence to a particular agent. Observers read a brief story in which an agent's intervention was followed by the target's compliance, noncompliance, or countercompliance to the request. The results indicated that influence was attributed to the agent in the conditions demonstrating change, i.e., compliance and countercompliance, regardless of the direction of that change. Additional findings indicated that influence attributed to an agent decreased if the target delayed final compliance with the intervention.     

Developmental differences in the allocation of processing capacity

Recently psychologists have formulated a comprehensive view of attention involving allocation of processing capacity. Although developmental changes in processing capacity have been proposed as one source of age differences in certain cognitive skills, there has been little systematic investigation of this hypothesis. In the present study, second and sixth graders and adults (8, 12, and 20 years of age, respectively) performed a letter-matching task (primary task) concurrently with an auditory detection task (secondary task). Changes in reaction time in the secondary task as a function of manipulations of the primary task were used to estimate capacity allocation to the primary task. Primary task variables included stage of processing (alerting, encoding, rehearsing, responding) and matching condition (physical-identity vs name-identity matching). Age differences in secondary task performance were found to be related to stage of processing but not to matching condition. Earlier stages of the letter match task (alerting, encoding) required somewhat more capacity allocation in younger subjects. Later stages (rehearsing, responding) made substantially higher demands on capacity in children. Capacity allocation may be an important cognitive variable mediating developmental differences in basic information processing skills, and may underlie age trends found in performance of certain complex cognitive tasks.     

Effects of altering outcome expectancies on pigeons' delayed conditional discrimination performance

An outcome-expectancy mediation theory of learning was tested in a series of transfer experiments with pigeons. The principal technique employed was a delayed two-choice conditional discrimination in which the subject's correct choice yielded a food reward on one kind of trial and a feedback tone on the other. According to the theory, this task engenders two-link mediational chains in that each conditional cue controls a particular outcome expectancy (S-E link) and the expectancy, in turn, cues a specific choice response (E-R link). Relative to the hypothetical mediators established by preceding training, transfer problems required either the same mediational chains, the alteration of one link in each chain, or the alteration of both links in both chains for optimal performance. The results of four separate transfer experiments confirmed detailed theoretical predictions, including that of an unusual nonmonotonic transfer effect. The relation of the present theory to earlier mediation theories is discussed.     

Similarity of attitudes and constructs in children's friendships

Sex prejudice in children's friendships has frequently been noted. This study examined the role of similarity of attitudes and personal construct ratings in this effect. Subjects were two classes of school children, aged 7–8 and 9–10 years. There were 29 children in each class. Subjects completed an attitude scale, construct rating scale, and sociometric questionnaire. Similarity effects were primarily in the younger children. Boys were more similar to each other in attitudes than were girls, and girls were more similar to each other in construct ratings than were boys (p < .001); there was greater similarity of attitudes and construct ratings in friendship rather than nonfriendship comparison dyads (p < .01). The sociometric data, when compared with sociometric data collected 6 months earlier, showed that these results could not be due to sex differences in the stability of friendships but rather suggested age and sex differences in the informational bases of friendships in middle childhood.     

An ERP study of sensory mismatch expressions in Japanese

Combinations of different sensory words produce mismatch expressions like smooth color and red touch in contrast to normal expressions like red color and smooth touch. Concerning these sensory mismatch expressions, results of three experiments are reported. Experiment 1 revealed that (i) mismatch expressions were less comprehensible than normal expressions, and that (ii) there were two patterns among mismatch expressions: the high-comprehensible mismatch expression (HighCME, e.g., smooth color) and the low-comprehensible mismatch expression (LowCME, e.g., red touch). Experiment 2 revealed that the mismatch expressions produced a significantly greater N400 amplitude than the normal expressions. Experiment 3 implied that the difference between High/LowCME was reflected in a later latency band or in a topographical difference of N400, although the statistical significance was marginal. It is argued that the processes to integrate linguistic elements (e.g., combining adjectives and nouns) are not homogeneous.     

Authoritarianism and PoliticalSocialization in the Context of the Arab-Israeli Conflict

This study explored the hypothesis that authoritarianism is negatively associated with peace supportiveness. A sample of 197 Jewish/Israeli university students responded to a questionnaire that included items on attitudes toward the Middle East peace process as well as a personality measure. The results confirmed the hypothesis: Individuals who were less supportive of the peace process were more authoritarian conformists than were supporters of the process. A significant association between religiosity and attitudes toward the peace process was also found; the split between peace supporters and non-supporters corresponded roughly, though not exactly, to the split between religious and non-religious. The pro-peace individual is generally non-religious, less authoritarian conformist, and less aggressive. Hence, the social cognitions studied—beliefs about the peace process—may be group beliefs. Certain characteristics of the groups in question, such as socialization practices and social structure, may account for the personality features that covaried with the beliefs. The data showing that peace attitudes, religiosity, and certain personality traits form one entity might thus be marshalled in discussing the identity issue and applied to other scenes in contemporary conflicts.     

Women and the Art of Peacemaking: Data from Israeli-Palestinian Interactive Problem-Solving Workshops

Are women “natural” peacemakers? If so, is this because of natural inclinations to avoid conflict or to engage in tough discussions? Are there particular skills in which women excel that make them more likely than their male counterparts to be able to build relational bridges, to facilitate negotiations, and to reduce tensions? After a review of the literature on gender differences in such skills, a systematic comparison of interaction quality is made between two Israeli-Palestinian interactive problem-solving workshops that differed only in gender composition. A third Israeli-Palestinian workshop that involved female political elites is also examined for subsequent changes in the conflict relationship or for changes in political activity. The implications of different repertoires of skills for altering political processes are discussed.
