An alternative scaling method for priorities in hierarchical structures

The early contributions of Saaty have spawned a multitude of applications of principal right (PR) eigenvector “scaling” of a dominance matrix [R]. Prior to Saaty's work (1977–1984) scaling of dominance matrices received little attention in multidimensional scaling, e.g., see Shepard (1972, pp. 26–27). This eigenvector method (EM) of scaling [R] yields u_i scores (weights) popularly used at each branching of the Analytic Hierarchy Process (AHP) technique that has been increasingly applied in multiple criterion analysis of utility, preference, probability, and performance. In this paper, it is proposed that an alternate least squares method (LSM) scaling technique yielding least squares optimal scores (weights) provides $\text{w}{}_{\mathrm{i}}{}^1$ values having a number of important advantages over u_i scores popularly utilized to date.     

The different types of limb apraxia errors made by patients with left vs. right hemisphere damage

Limb apraxia errors were compared among normal controls and right- or left-hemisphere-damaged patients as they imitated gestures with the ipsilateral hand. Both brain-damaged groups made similar errors on nonrepresentative and representative/intransitive movements. In contrast for pretended object use movements (transitive), the left-hemisphere-damaged group made more arm position and classical body-part-as-object errors while the right hemisphere group made as many partial errors and more less-primitive, body-part-as-object errors than the left-hemisphere-damaged group. These results help explain why a certain percentage of right-hemisphere-damaged patients are labeled apraxic, but also suggest that the left hemisphere is more important for integrating intrapersonal space and the “representation” of extrapersonal space.     

Moral reasoning development and graduate education

The Defining Issues Test (DIT) of moral reasoning development was administered to 20 advanced and 20 first-year graduate students, plus 40 college graduates matched to the graduate groups on sex, age, and verbal ability. A two-way ANOVA design was used to infer whether graduate education, selection, maturation, or a combination of these effects is (are) associated with group differences on the DIT. Results suggest that differences found between the graduate students and college graduates can be accounted for by a combination of maturational and selection effects, contrary to the hypothesized effects of formal education.     

Incidental learning in preschool children as a function of level of cognitive analysis

Preschool children's recall and clustering of organized lists of pictures were examined under deliberate instructions to remember or in incidental learning situations. The incidental tasks either required comprehension (categorization, or a rating of pleasantness-unpleasantness) or were formal orienting tasks involving processing in terms of physical features.Explicit instruction to remember and formal incidental instructions did not differ, and both lead to poorer performance than the comprehension activities. Categorization, whether accompanied by explicit instructions to recall, or occurring in the context of a meaningful activity, was no more efficient than categorization in and for itself. With children as with adults, it is the activity of the children which determines depth of processing and subsequent retention, not the intent to remember per se.     

Differences among medical,business, and engineering students in the intensity and direction of their affective responses to occupational concepts

A semantic differential was used to measure the affective responses of vocationally committed male students in medicine, business, and engineering to occupational concepts representing the fields of medicine, business, engineering, the clergy, and law enforcement. A factor analysis of the data indicated that the students responded to the concepts with the Evaluative, Activity, and Potency dimensions of affective meaning. It was found that the groups differed significantly in the intensity and direction of their affective responses to the occupational concepts on the Evaluative and Activity dimensions. An examination of the nature of the group differences indicated that they held different affective meanings for their respective vocational choices, and for other occupational concepts as well. The medical students responded to medicine as good, potent, and active; the business students to business as bad, potent, and active, and the engineering students to engineering as good, weak, and active. The possible relationship of affective meaning to vocational behavior was discussed.     

Semantic integration in children's reconstruction of narrative sequences

Preschool to fourth grade subjects were required to reconstruct a previously seen logical sequence by selecting old items from a set containing actually seen events and two types of new items, those consistent or inconsistent with the ordered sequence of the story. Older children were more efficient at adopting a consistent choice strategy, at rejecting inconsistent items and at retaining the end-anchor items of the story. When performance on the old anchor items was excluded, however, all grades had difficulty distinguishing the new-consistent items from the actually experienced old items. It is suggested that memory for logical narrative sequences involves the retention of the gist or theme in an integrated unified representation of the meaning rather than a series of discrete events. Further, the underlying processes of integration and inference are stable across ages.     

Comparative validity of traditional versus S-R format inventories of interpersonal behavior

The comparative validity of two “S-R format” inventories of interpersonal behavior, Kinnane et al.'s (1969) Schedule of Interpersonal Response and a newly developed Rational S-R Inventory, and two “traditional” inventories, the Personality Research Form and the Interpersonal Check List, was examined with respect to 14 self-report and peer rating criteria selected to broadly tap the interpersonal domain. Sixty-four male and female high school seniors served as Ss.In spite of the situational specificity inherent in the S-R inventories, the traditional inventories substantially outperformed the S-R inventories and, in contrast to previous findings, also outperformed simple self-ratings. The results are discussed not only in terms of the relative advantages of various inventory construction strategies but also in reference to the problem of criterion measurement and theoretical and methodological issues in the assessment of situational parameters.     

Limb apraxia and motor performance

This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger tapping task. Although task complexity or sequencing requirements affected group differences, greatest apraxic impairment was noted on a task of precise steadiness, but only when its response inhibition requirements were increased. This pattern of deficits appears to be associated with greater involvement of the premotor area in the apraxic group.     

Aphasic adults' use of heuristic and structural linguistic cues for sentence analysis

Eight aphasic adults with relatively preserved auditory comprehension and 12 normal adults were tested for their ability to analyze sentences in which the functional relations between the verb and nouns was either directly reflected by word order expectancies, or marked by a functor or non-NVN word order. The subjects' task was to designate the agent of each sentence. Results indicated that aphasics utilize word order expectancies but are impaired in their ability to exploit functors and particularly, word order markers for sentence analysis. Results are discussed in terms of aphasics' use of heuristic versus structural linguistic cues for interpreting sentences.
