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.     

Response to Requests for Abortion: The Influence of Guilt and Knowledge1

Participants who varied in their levels of sex guilt and sexual knowledge indicated the extent of their approval for abortion in response to 10 case histories of abortion applicants. The case histories were varied in terms of the circumstances under which conception had occurred. Sex guilt was significantly related to abortion decisions while sexual knowledge registered little effect. Low sex guilt students were more favorable toward abortion requests than were high sex guilt students, but both groups were more favorable toward abortion when conception was the result of failure of a contraceptive method than when it was due to the applicant's inconsistent use of the method. In addition, high sex guilt students' abortion decisions were significantly influenced by the relationship of the applicant to her coital partner. When the relationship was “steady,” they approved the request, whereas abortion was denied to the applicant who conceived with a casual partner. The results were discussed within the context of the debate over the morality of abortion and the problem of unwanted adolescent pregnancy. It was suggested that sex guilt may play a larger role in these issues than has been previously recognized, and that presenting the “facts” (sexual knowledge) may have little impact in abortion related decisions.     

Semantic memory: Searching for attributes vs searching for names

The purpose of this experiment was to determine whether searching for a word that has a particular attribute (a fruit that is yellow) involves a different process than searching for a word whose name has a particular form (a fruit whose name begins with "p"). Ss saw category nouns paired with adjectives or letter restrictors presented on a series of blocked trials and a series of mixed trials. The Ss had to produce a word that fell in the space defined by the noun and the restricting adjective or letter. RT was fastest when trials were blocked and when a letter followed the presentation of the noun. This finding suggested the existence of two retrieval plans that can be executed when S has knowledge of the forthcoming type of item.     

Lasting effects of early blindness a case study

A young woman, blinded by the development of corneal opacity at the age of 3 years, was given a corneal graft at the age of 27. Though the image-forming powers of the eye were largely restored, the patient showed little recovery of functional vision. Six months after operation she could detect and locate conspicuous objects and had some degree of ambient spatial vision but she could not learn to recognize simple visual patterns. Eventually she reverted to the life of a blind person. Her failure to recover is discussed in terms of the known deleterious effects of restricted early visual experience on the development of the visual cortex in animals.     

Visual span of apprehension in patients with unilateral cerebral lesions

The visual span of apprehension for random letter and digit sequences, approximations to English sequences and non-symbolic line stimuli was measured in patients with unilateral cerebral lesions. The left hemisphere group was significantly impaired relative to the right hemisphere group and a control group on all three types of visual span task. The deficit was most marked in patients with left posterior lesions. The visual span deficits were not related to other language deficits. The findings are discussed in terms of a modality-specific defect of visual short-term memory.     

Piaget's Grouping II: The model, its assessment, and the effects of training

Although Piaget emphasized the importance of negation in equilibration theory, few data are available pertaining to children's use of Grouping II (Gr. II) logic, which relies on negation. Three approaches to assessing Gr. II capability are reviewed in light of Piaget's (1949, Traité de logique: Essai de logistique opératoire, Paris: Colin) discussion of Gr. II. The paper describes a new task to assess three aspects of Gr. II thought: (a) naming secondary classes, (b) comparing a secondary class with a primary class contained within it, and (c) reasoning about vicariance relationships. An experimental group of third graders trained to use Gr. II logic performed significantly better on post-test tasks than did an untrained control group. Training included rule instruction, evaluative and informative feedback, and manipulative activities.     

Ethnic Variations of Trajectories in Suicide Ideation and Attempt: From Middle School to High School

The purpose of this study was to compare patterns of suicide ideation and suicide attempt in three ethnic groups. We analyzed data from 463 students with ethnic backgrounds of African American (AA), Asian American (ASA), and European American (EA) for 6 years. The best fit model was a three‐trajectory class model for all groups. The majority of adolescents belonged in the nonideators trajectory. The high level of ideation was found in the high ideators (4%), high‐fluctuating ideators (8%), and high‐decreasing ideators (4%) trajectory in AA, ASA, and EA, respectively. In the AA group, being a member of ideators was not a significant predictor of suicide attempt. In the ASA group, being a member of high‐fluctuating ideators was a significant predictor. In the EA group, being a member of both ideators predicted suicide attempt. The timing of onset, patterns of change, and peak time in the ideators trajectories in the three ethnic groups were markedly different. The high level of attempts found in the ASA–AA group was not explained by having suicide ideation. Findings suggest the need for in‐depth examination of suicide behaviors across ethnic groups and culturally adapted preventive efforts with distinct developmental timing for adolescents from different ethnic backgrounds.
