Content analysis: a comparison of manual and computerized systems

Computerized content analysis is a technique for classifying texts. In personality research it has been used to make inferences about psychological states and traits of the speaker or writer. Whereas computerized techniques have been increasing in both sophistication and ease of use, questions remain regarding their validity compared to hand-scored scales. In this study, we compare a relatively simple computerized technique; a more sophisticated, context-sensitive computerized approach; and a context-sensitive, human-scored system. Seventy-one subjects, representing four diagnostic groups, provided free-speech samples which were scored according to all three methods. Data from each method were then submitted to discriminant and classification analyses. In comparing the classification performance of the three methods, we found that both computerized methods were more accurate than the human-scored method. The time and cost benefits of computerized systems are discussed.     

Item factor structure of the Personality Adjective Check List

This study reports on a principal-components analysis of the Personality Adjective Check List (PACL) at the item level. Data came from a national sample of normal adults and included the responses of 1,058 men and 1,194 women (N = 2,252). Analyses were conducted separately for men and women, and for the sexes combined. The scree test was applied to decide on the number of factors to extract. Retained factors were rotated by varimax and direct oblimin procedures. Results were very similar for each analysis, with coefficients of congruence for the five orthogonal factors obtained from men and women separately being .95, .92, .94, .94, and .92. The five unipolar personality dimensions isolated were interpreted as Aggressive/Dominant, Neurotic, Conscientious, Detached/Introverted, and Surgent/Extraverted. These were compared to item factors of the Million Clinical Multiaxial Inventory (MCMI-I), MCMI-II, Adjective Check List (ACL), and to Norman's Big Five dimensions.     

Religious self and secular self: Clinical transitions

Clerical people, returning to secular life, may undergo shifts in self-experience, including alterations in internal object relations. Self-psychology, positing the importance to health of cohesion of all aspects of self, provides a theoretical model for exploring such shifts and their facilitation through psychoanalytic psychotherapy. A case of a released Roman Catholic priest is discussed to illustrate dynamic processes. Emphasis is on a clinical approach that does not require conversion of religious and spiritual self-experience into drive derivative formulations     

Assertiveness and social anxiety in Chinese-American women

The notion that Chinese Americans, compared to Caucasian Americans, are passive and nonassertive was examined with self-report and behavioral measures. Chinese-Americans (n = 36) and Caucasian (n = 19) female college students were randomly assigned to one of two conditions: role-playing a series of 13 situations requiring assertion with an Asian experimenter or role-playing the same situations with a Caucasian experimenter. The Chinese-American students were as assertive as the Caucasian subjects on all behavioral measures. Only one self-report measure, the Fear of Negative Evaluation Scale (Watson & Friend, 1968), revealed a significant difference between the two groups; Chinese-American students were more apprehensive about social situations than Caucasian students.     

Negative priming in same-different matching: further evidence for a central locus of inhibition

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as "same" or "different." Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.     

An asymmetry in transmodal perceptual learning

Transmodal perceptual learning was examined in a canonical same/different paradigm. Subjects naive to vibrotactile stimulation and unfamiliar with the task were asked to discriminate sequentially presented shapes moving laterally across an aperture. On all trials, the shapes were presented either visually and then vibrotactually or in the opposite modality order, and on all trials the shapes moved in opposite directions. Analyses of the data revealed that although perceptual learning was evident in both groups, the rate of the learning was more rapid in the visual-vibrotactile group. This interaction of modality order and practice was significant and was considered in terms of E.J. Gibson's theory of perceptual learning and in terms of the constructs, suggested by J.J. Gibson, of available and accessible information-in-stimulation and the education of attention.     

Mental retardation and perception of global motion

We have found that mildly mentally retarded adults are impaired in their perception of global stereoscopic forms (Fox & Oross, 1988) in ways that cannot be attributed to peripheral visual deficits or failures to comprehend. To assess the generality of that result, we measured the ability of mentally retarded adults to perceive kinematographic forms. Mentally retarded and nonretarded adults were presented with a two-choice, forced-choice detection task requiring the location of a target's spatial position. The discriminability of the forms was varied by systematic reductions in both element density and temporal correlation. We found that, relative to nonretarded adults, mentally retarded adults exhibited large qualitative deficits in their ability to discriminate these kinematographic forms when either density or correlation was reduced. After considering a number of alternative interpretations of these data based on factors such as peripheral visual impairment and a failure to attend, we could find none more compelling than a perceptual interpretation, which posits a deficit within the short-range motion system.     

Information-processing differences and laterality of students from different colleges and disciplines

1023 college students were assessed for hemispheric brain dominance using the paper-and-pencil test, the Human Information Processing Survey. Analysis of scores of students majoring in Advertising, Interior Design, Music, Journalism, Art, Oral Communication, and Architecture suggested a preference for right-brain hemispheric processing, while scores of students majoring in Accounting, Management, Finance, Computer Science, Mathematics, Nursing, Funeral Service, Criminal Justice, and Elementary Education suggested a preference for left-hemispheric strategies for processing information. The differential effects of hemispheric processing in an educational system emphasizing the left-hemispheric activities of structured logic and sequential processing suggests repression of the intellectual development of those students who may be genetically favorable to right-hemispheric processing.     

Effect of visuomotor rehearsal with videotaped modeling on racquetball performance of beginning players

This investigation was designed to assess the effect of visuomotor behavior rehearsal (VMBR) with videotaped modeling on racquetball performance of beginning players. 24 male students in beginning racquetball class were randomly assigned to either VMBR with videotape modeling or relaxation and imagery (no modeling) condition for a 2-wk. training period. All subjects were pre- and posttested on forehand and backhand racquetball skill tests. Analysis indicated an effect for forehand shooting, with those given visuomotor behavior rehearsal with videotaped model exhibiting better performance than the relaxation and imagery group, but no effect for backhand shooting.     

Concurrent validity of the motor domain of the Vineland Adaptive Behavior Scales

The concurrent validity of the motor domain from the Vineland Adaptive Behavior Scales was estimated using scores from the Peabody Developmental Motor Scales as criteria. A moderately high correlation between the measures was obtained. Implications, particularly for preschool children, were discussed.
