Line bisection and cognitive plasticity of unilateral neglect of space

Patients with neglect of the left half of space were asked to bisect lines of different lengths. The leftmost points of the represented lines, determined on the basis of the midpoints set by the patients on the objective lines, were the dependent variable. It was thus possible to recognize diverse patterns of behavior which were conceivably averaged away in earlier investigations. In discussing the results, the question is raised of whether unilateral neglect of space may be altered by cognitive processes.     

Anatomoclinical correlations of the aphasias as defined through computerized tomography: Exceptions

We have studied the frequency of exceptions to classical aphasia localizations in right-handed, literate, adult, native speakers of Italian with focal vascular left-hemisphere lesions, correlating clinical and computerized tomography data. Two hundred sixty-seven subjects were given computerized tomography (CT) examinations; lesions were mapped onto lateral diagrams and the sites of the lesions were defined. Patients were then classified as nonfluent aphasics, fluent aphasics, and nonaphasics. Patients with negative CT scans (n = 10) or only "deep" lesions (n = 50) were not studied for anatomoclinical correlations. Of the remaining 207 patients, 36 presented unexpected findings. There were seven cases of fluent aphasia and "anterior" CT lesions and six cases with nonfluent aphasia and "posterior" CT lesions among them. The significance of these findings is discussed.     

Relative clause structure, relative clause perception, and the change from SOV to SVO.

This study presents a view of diachronic change in language, according to which one of the fundamental factors motivating syntactic change is to be found in the conflicting interaction of principles determining the language organization. Specifically, it will be argued that principles of structural nature and principles of perceptual nature are in conflict in languages of the SOV type, because of the relative clause construction. The way in which a relative clause is structured in an SOV language is an obstacle to its effective perceptual processing. It will be argued that this conflict is one of the major factors determining the diachronic change of a language from an OV to a VO typology.     

Selective deficit of conceptual structures in aphasia: Class versus thematic relations

Conceptual structures in aphasia were investigated by means of a nonverbal test. The understanding of class and thematic relationships was demonstrated to be selectively impaired according to varieties of aphasic deficit. Broca's aphasics showed difficulty evaluating a thematic relationship and did not differ from normal controls as far as class relationships were concerned. The opposite happened for Wernicke's aphasics whose defect seems to be selectively restricted to class relationships.     

Lateral preferences and writing hand posture in left-handers: A reply to Levy

In reply to the commentary from J. Levy about a recent article of ours (A. Searleman, C. Porac, & S. Coren, 1984, Brain and Cognition, 3, 86–93), we find that she has shifted the level of analysis from between-sex comparisons (as demanded by our original hypothesis) to within-sex comparisons. Since she is addressing a different set of questions, we therefore find no compelling reasons to alter any of our conclusions or the confidence that we have in these conclusions.     

Individualized learning environments: Intra- and interpersonal consequences

This study examines the effects of individual goal structures on the intra- and interpersonal behavior of 120 fourth-grade children. Each group of four children was introduced to one of two individualized learning programs: (a) workbook materials color-coded according to level of difficulty (allowing implicit comparisons among children as to progress), and (b) materials not coded according to difficulty (discouraging comparisons). In both learning programs, children worked individually (at story writing) and were rewarded for the work. Results indicate that boys, but not girls, who were rewarded equally for doing good work in an individualized setting but who start and end at a lower step than other more frequently took away a toy from those peers with whom they compared themselves than did boys who were rewarded equally for good work and where there were no comparisons. Boys as a group, regardles of condition, gave more prize tickets to themselves than to others and gave more prize tickets to themselves than girls gave either to themselves or others. Both boys and girls appear to adopt the evaluations of their work given by the experimenter and appear to be influenced thereby in later prized-giving to themselves and to others.     

The nature of curiosity in children

This study examined several behaviors claimed to reflect curiosity in order to determine whether there are one or more types of curiosity. A secondary purpose was to examine the relations between the one or more types of curiosity and sex, social class, intelligence, achievement level, and ratings of personality traits. In two individual sessions 84 American first-grade boys and girls were administered five tasks which measured observation of complex and simple stimuli, preference of complex and simple stimuli, preference for the unknown, structure of meaning, and object exploration. A normalized Varimax factor analysis allowed the extraction of five factors: manipulatory curiosity, perceptual curiosity, conceptual curiosity, curiosity about the complex, and adjustive-reactive curiosity. Only the first factor was related to a demographic variable, sex. The nature of the factors and their theoretical and practical significance are discussed.     

On the relationship of data to theory: A reply to Ronis and Greenwald

Ronis and Greenwald (Dissonance theory revised again: Comment on the paper by Fazio, Zanna, and Cooper. Journal of Experimental Social Psychology, 15, 1979, 62–69) question our integrative formulation of dissonance and self-perception processes. We argue that our formulation provides an explanation of both the full range of results in the literature and our own experimental data, while neither dissonance nor self-perception theory can singly explain the existing data.     

Selection of consultees in school mental health consultation

To further understanding regarding the selection of teacher consultees, 15 mental health consultants completed a questionnaire. Consultants ranked teachers in their school consultation placements on ability to meet academic and socioemotional needs of children, receptivity to change, and likability. Next, after indicating which teachers they would most and least like to work with, consultants rated the teachers on nine 5-point rating scales. In general, results indicate that most preferred consultees, in comparison to least preferred consultees, are perceived as less needy of assistance around issues concerning children and lessons, more responsive to consultation, and more likable. It appears that teachers most in need of assistance are not selected for consultation.     

Social inhibition as a function of observation and recording of performance

In order to compare the relative effects of observation of performance and recording of information about performance on social facilitation/inhibition, 256 college students solved three concept-attainment problems in an orthogonal design. The variables were (a) number of observers (an additional observer or the experimenter alone), (b) videorecording (yes or no), (c) audiorecording (yes or no), (d) task complexity (four, six, eight, or ten total attributes in the problems). Each of videotaping, filming, and audiotaping resulted in poorer performance than the control condition, with no differences between these three recording conditions. The presence of an additional observer had no effect on performance. Pulse measures indicated that the presence of an additional observer increased arousal, but covariance analysis indicated no association between differences in performance and arousal.     

Persistence of response prevention effects following retraining of escape behavior

This study evaluated the effects of response prevention procedures on the extinction of escape behavior following the reinstatement of shock-escape training prior to the start of extinction. Female hooded rats were assigned to four groups (N = 10) in a factorial design which orthogonally combined response prevention or pseudo-prevention procedures with escape retraining or no retraining procedures. Results showed that prevention reliably impaired shock-escape behavior on early retraining trials; but this effect dissipated completely by the end of retraining. In extinction, prevention reliably facilitated the extinction of escape behavior relative to that of pseudo-prevention controls; but the degree of facilitation was reliably attenuated by retraining procedures. These findings were related to the competing response interpretation of prevention effects.     

Commentary on social class differences in sociodramatic play in historical context: A reply to McLoyd

Historical origins of the research on the cultural correlates of imaginative behavior by the Israeli psychologists Feitelson, Smilansky, and Eifermann are presented. It is argued that despite McLoyd's searching analysis of the deficiencies in studies which attempt to relate level of imaginative play to social class, those earlier cross-cultural studies, together with some 50 years of prior research on social class and play in general, provide a context which gives support to those studies despite their particular methodological deficiencies.     

II. The comparability of the WISC-R and WAIS among 16-year-old EMR children

Thirty 16-year-old EMR children were administered the WAIS and WISC-R in counterbalance order to determine the comparability of the two assessment instruments. The WAIS was found to yield significantly higher Verbal, Performance, and Full Scale IQ scores. The comparisons of corresponding subtests indicate that all WAIS subtests were significantly higher than the WISC-R except Picture Completion. Correlations between corresponding WAIS and WISC-R IQ scales and subtests, however, were significant. The results suggest differences between the two instruments among children of subnormal intelligence, thus presenting the possibility that a child may be differentially classified based on the selection of the intelligence test.     

Knowledge of one's own responding and the relation of such knowledge to learning: A developmental study

First-, third-, fifth-grade children, and college students (ages 6, 8, 10, and 19 years) acquired a paired-associate list under the study-test procedure to a one error-less trial criterion. In addition, as each pair was presented the individual indicated whether he/she had that pair correct on the immediately preceding trial (postdiction responses). The data were interpreted in terms of a discrimination-utilization hypothesis which postulates that individuals discriminate their own correct and incorrect responses on a given trial and use this information for distributing processing effort on the subsequent trial. Analyses involving the accuracy of postdiction responses, the relation of postdiction accuracy to acquisition, and the consideration of the acquisition data in terms of a two-stage model led to the conclusion that older children and adults may use the discrimination-utilization strategy but younger children tend not to use it, probably because of both mediation and production deficiencies.     

Affordances and infant learning: A reply to Horowitz

We reply to three major points made by F. Horowitz (1983, Developmental Review, 3, 405–409) in her commentary on the ecological approach to infant knowing presented by E. Goldfield (1983, Developmental Review, 3, 371–404). We first clarify the relation between perceiving and acting from an ecological perspective, and distinguish between affordances as environmental properties scaled to the perceiver/performer and representations as mental structures. We then present a critique of the process of association offered by Horowitz as an explanation of infant learning. Association fails to specify the constraints on what is learned, while the ecological process of noticing affordances, presented by Goldfield, considers such constraints. We conclude by presenting operational criteria for measuring affordances and evidence that perception is scaled to the perceiver/performer.
