Agrammatism in a case-inflected language: Comprehension of agent-object relations

Yugoslav agrammatic aphasics and normal control subjects were tested for comprehension of agent-object relations in a series of simple Serbo-Croatian sentences consisting of two nouns (N) and a transitive action verb (V). The availability of nominative and accusative case inflections and a semantic contrast was systematically varied across sentences. Sentences were also varied with respect to the two sequences NVN and VNN. An analysis of subjects' agent-object assignments yielded the following results: While Broca's aphasics did show some sensitivity to case inflections, their ability to process such cues was greatly impaired relative to normal subjects, for whom morphological cues were almost completely deterministic. To a lesser degree, Broca's aphasics were impaired in their ability to employ a strategy of “choose the first noun as agent” when case inflections and semantic contrasts were not available. While Broca's aphasics showed no impairment in their ability to exploit semantic contrasts for agent-object assignment, there was no absolute compensatory increase in the degree to which they relied on semantic cues. Differences in word sequence had no effect on agent-object assignment in Broca's aphasics. Finally, Broca's aphasics frequently responded unsystematically when cues to agent-object relations occurred in isolation or in competition with one another, but when there was a convergence of cues their performance approached that of normal subjects. This result was interpreted in terms of an accessing hypothesis.     

Attributions and other inferences: Processing information about the self versus others

This study focuses on the attributional inferences involved in the comprehension of behaviors and on possible differences between the process of comprehending one's own behaviors and those of another person. Both the content of attributional judgments and the time taken to make the judgments were measured, in a design involving the comprehension of behaviors that were high or low in desirability and distinctiveness and that were understood as the subject's own versus another person's. Results show that the inferential processes in the comprehension of one's own and another's behavior are generally similar. Exceptions are where organized knowledge about the self (a self-schema) is brought into use and where differences in “perspective” between self and other influence processing. Discussion centers on the implications of the results for theories of comprehension and inference, including extensions needed to handle the self/other distinction.     

On the adequacy of prototype theory as a theory of concepts

Prototype theory construes membership in a concept's extension as graded, determined by similarity to the concept's “best” exemplar (or by some other measure of central tendency). The present paper is concerned with the compatibility of this view of concept membership with two criteria of adequacy for theories of concepts. The first criterion concerns the relationship between complex concepts and their conceptual constituents. The second concerns the truth conditions for thoughts corresponding to simple inclusions.     

When increasing liking for a communicator decreases opinion change: An attribution analysis of attractiveness

Fifty-six female subjects were asked to discuss, through passing notes, a personal injury case with a partner. Liking for the partner was manipulated by informing subjects either that their partner was very cold and penurious (low attractiveness), or was very warm and generous (high attractiveness). During the discussions, the partners' notes were replaced by notes that argued for either a very low or a very high amount of compensation. Though the general rule is that influence should mirror liking, attribution theory (Kelley, 1967) leads to the expectation that in this setting the persuasiveness of the liked versus the disliked partner should depend on the amount of compensation advocated, with low compensation arguments being more persuasive when believed to be given by the liked partner, but high compensation arguments more influential when believed to be given by the disliked partner. The results supported attribution theory. Implications for the way attractiveness has been conceptualized in the social psychology literature are discussed.     

Analysis of the development of children's spatial reference systems

Four, six, and ten-year-old children were required to copy an object's location and orientation within a two-dimensional spatial layout under two conditions: when both E's standard board and that of the S's were in the same orientation and when they were rotated 180 ° from each other. The failure of the 4-yr-olds to copy location and orientation under both conditions even when space was topographically coded indicates that at this age the child does not conceptualize space within two dimensions. Although the errors of the 4-yr-olds tended to be of a self-reference nature with respect to orientation and location on rotation trials the axes of the self-reference system were not coordinated. Six and 10-yr-old children performed significantly better on both conditions, with the exceptions that the 6-yr-olds continued to preserve some orientations within a self-reference system. When topographical codes were removed and S imagined rotation there were no significant age differences in total errors; however, older children organized entire subspaces within a self-reference system. The findings support Piaget and Inhelder's hypothesis that two-dimensional reference systems do not develop until the period of concrete operational thought, and they also indicate that even at age 10, the self-reference system continues to function when topographical codes are absent. Several cognitive mechanisms proposed to account for the development of spatial abilities are critically discussed.     

Reference group perspectives and the vocational maturity of lower socioeconomic black youth

The reference group perspectives of 188 lower socioeconomic black high school seniors were found to be related to their career maturity. Students who evidenced an orientation toward middle-class reference group perspectives obtained higher vocational maturity scores than those who subscribed to reference perspectives traditionally associated with the lower class. Students' sex and family background were not related to their reference group perspectives or to their vocational maturity ratings. It was found that students' post-high school plans (either work- or college-bound) and their views of the opportunity structure of America were related to both their reference group perspectives orientation and their career maturity scores. Questions are raised concerning the relevance of the term career maturity for analyzing the career development of lower socioeconomic black youth.     

Habituation and dishabituation of the electrodermal orienting reflex in relation to extraversion and neuroticism

Orienting reflex (OR) habituation and dishabituation may be influenced by individual difference variables, including Eysenck's Extraversion (E) and Neuroticism (N) dimensions. Ninety subjects formed nine groups based on the crossover of high, medium, and low E and N. Each subject received, at each of two auditory stimulus intensities, two blocks of tone presentations. The last standard stimulus trial was followed by a novel stimulus and four repetitions of the standard stimulus. Using square root SCR, extraverts showed smaller initial response amplitudes than introverts at the low intensity of stimulation, while the reverse was true at high intensity. E and N were unrelated to SCR habituation rate. However, extraverts showed no dishabituation, while introverts did dishabituate.     

Memory for companions in preschool children

Memory of preschool children (4 years of age) for companions was investigated by comparing interview data using a picture sociometric technique with observational data on actual play companions. Accuracy decreased with successive nominations, and length of recall period. However children were able to name companions played with today, yesterday, last week and at the beginning of term, at well above chance levels. Accuracies improved during the term. The relevance of friendships and social experience for memory and cognitive processes in young children is discussed.     

Putting the lie on the control condition for moral responsibility

In “Control, Responsibility, and Moral Assessment” Angela Smith defends her nonvoluntarist theory of moral responsibility against the charge that any such view is shallow because it cannot capture the depth of judgments of responsibility. Only voluntarist positions can do this since only voluntarist positions allow for control. I argue that Smith is able to deflect the voluntarists’ criticism, but only with further resources. As a voluntarist, I also concede that Smith’s thesis has force, and I close with a compromise position, one that allows for direct moral responsibility for the nonvoluntary, but also incorporates a reasonable control condition.
