Concurrent validity of Holland's theory for college-degreed black women

This study, using the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS), explored the concurrent validity of Holland's theory for employed college-degreed black women. The VPI and SDS were administered to 93 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed college-degreed black women.     

Developmental verbal control of behavior: Implications for self-instructional training

Kindergarten, first-grade, and second-grade children (5, 6, and 7 years of age, respectively) performed a Luria-type verbal control task in which motor responses are initiated to positive stimuli and inhibited to negative stimuli. The task was performed by motor responding only and verbal self-directed motor responding, with these conditions reversed in sequence for one half of each grade group. Although motor responding and verbal-motor responding by the two younger groups were generally poor, their performance equalled that of the second graders when the verbalizing condition followed the silent, motor-only condition. For these children, verbalizing appeared to constitute a second task which interfered with motor responding. Prior practice on motor-only responding, however, facilitated subsequent, concurrent performance of the two tasks. No interference or practice effects were found for the second graders. The results suggested that self-instructional training programs are likely to be successful when adequate verbal-motor coordination can be assumed or when the motor response is within the child's repertoire.     

Personality characteristics,parent behaviors,and sex of subject in relation to cheating

College students were given the opportunity to falsify self-reported scores on a task to gain course credit. Personality and perceived parent behavior data were obtained in a counterbalanced design. Male cheaters were significantly higher in Aggression, Exhibition, Social Recognition, and Harmavoidance but lower in Autonomy (PRF scales) and ACT scores. Female transgressors were reliably lower in harmavoidance and higher in Impulsivity than noncheaters. Among males, no parent scales differentiated transgressors and resisters. Among females, parent scales reflecting reports of lower father warmth and fewer maternal equalitarian interactions but higher Hostile Control significantly differentiated cheaters from noncheaters. These findings were discussed, particularly in terms of the sex differences which suggest that males and females may cheat for different reasons.     

Center median "alerting" and verbal learning dysfunction

Previous data have shown that stereotaxic center median lesions alone or lesions in the amygdala, unilateral left and right and bilateral, do not impair verbal paired-word associates learning. However, “interactional” combined lesions in the amygdala and center median nucleus on the left side result in a significant decrease in test scores. Analysis of the types of errors made postoperatively by the six patients with this lesion combination indicates the persistence over trials of misnaming errors vs errors of omission. These findings are compatible with hypotheses of an alerting function performed by medial thalamic structures which, for effective learning, cosponsor attention to stimulus cues. Defective alerting is held to result in faulty labeling and subsequent mismatching (see Ojemann, 1975, Brain and Language, 2, 101–120, and Fedio &; Van Buren, 1975, Brain and Language, 2, 78–100).     

Anxiety and sex role in body landmark functions

Two hypotheses were evaluated. One proposed that the more prominent a body landmark the less anxiety will be evoked by a theme linked to that landmark. The relation was determined between landmark prominence and anxiety evoked by a taped message appropriate to the landmark-linked theme. Two female samples were studied. The findings supported the hypothesis. A second hypothesis proposed that enhancing awareness of body landmarks under threat conditions is positively related to degree of masculinity and negatively related to degree of femininity. Changes in landmark awareness during appropriate taped messages were studied in two male and two female samples. Masculinity-femininity was also measured. The findings were particularly supportive of the hypothesis relating masculinity to mobilization of landmarks.     

Interacting plans

The paper explores certain phenomena which arise in stories, conversations, and human activity in general when the plans of two individuals are formed and carried out in an interactive situation. A notation system for representing interacting plans is introduced and applied in the analysis of a small portion of “Hansel and Gretel.” The analysis illustrates how a single actor plan can be modified by the needs of cooperative interaction with others and how cooperative interactive episodes can be transformed and used deceptively by one party in achieving his or her own covert goals.     

Diagnostic models for procedural bugs in basic mathematical skills

A new diagnostic modeling system for automatically synthesizing a deep-structure model of a student's misconceptions or bugs in his basic mathematical skills provides a mechanism for explaining why a student is making a mistake as opposed to simply identifying the mistake. This report is divided into four sections: The first provides examples of the problems that must be handled by a diagnostic model. It then introduces procedural networks as a general framework for representing the knowledge underlying a skill. The challenge in designing this representation is to find one that facilitates the discovery of misconceptions or bugs existing in a particular student's encoding of this knowledge. The second section discusses some of the pedagogical issues that have emerged from the use of diagnostic models within an instructional system. This discussion is framed in the context of a computer-based tutoring/gaming system developed to teach students and student teachers how to diagnose bugs strategically as well as how to provide a better understanding of the underlying structure of arithmetic skills. The third section describes our uses of an executable network as a tool for automatically diagnosing student behavior, for automatically generating “diagnostic” tests, and for judging the diagnostic quality of a given exam. Included in this section is a discussion of the success of this system in diagnosing 1300 school students from a data base of 20.000 test items. The last section discusses future research directions.     

Comparing natural and abstract categories: A case study from computer science

In order to address the issue of whether abstract and concrete objects are categorized similarly, this paper looks at how computer scientists categorize the common concepts of their field. Using the methodology of Rosch, Mervis, Gray, Johnson, and Boyes-Braem (1976) and of Rosch and Mervis (1975) to identify the categorizations used by computer scientists, this study found that the categorization phenomena reported for concrete objects are quite general, operating over a wider range than was previously thought.
