Evaluation of visual display surfaces by real users early in the design stage

Groups of non-computer scientists were tested to evaluate the potential of an as yet non-existent interactive terminal with a screen diagonal of one meter. A simulated large image terminal provided limited realistic interactions using software developed to give close proximity to the predicted visual effect. Subjective responses from 101 subjects were elicited from a questionnaire designed to evaluate specific aspects of the “terminal” in use. From this data, two types of screen (lenticular and plain) and two types of interaction devices (touch and remote pointer) were analyzed experimentally using a two-way factorial design. Potential end-users provided positive feedback concerning future use of the Large Image Terminal. Building a realistic mock-up revealed screen contaminations which would not have been discovered until a much later stage. Although statistical analysis of screen evaluations was equivocal, the questionnaire was sufficiently penetrating to separate the positive and negative features. This methodology was invaluable in guiding the design process. Copies of the questionnaire may be obtained from the authors at the Heriot-Watt address.     

Preemployment screening procedures: How human resource managers perceive them

A survey of Human Resource practitioners' perceptions of pre-employment screening procedures was conducted. The results indicated differences between tests in terms of perceived accuracy and offensiveness, as well as other attributes. Regression analyses suggested that beliefs about validity, the number of other companies using these procedures, perceived offensiveness of the test, and ease in passing the test were important factors in the willingness to use a particular test. Conversely, perceptions regarding the discriminatory impact of the test and the cost of using the test generally were not related to willingness to use the test. Limitations of this study, which was primarily exploratory, are noted.     

Racial Identity Development Among Gifted Black Students: Counseling Issues and Concerns

A review of the literature suggests that a paucity of information exists regarding how culture-specific issues such as being both Black and gifted influence the psychological needs and personality development of gifted Black students. Stellar attempts, however, are currently underway to develop theories and perspectives of racial identity development among Black students. These theories and perspectives are discussed in an attempt to understand and address the psychological and social needs of gifted Black students.     

Child and adolescent psychopathology research: Problems and prospects for the 1990s

In November 1990 the National Institute of Mental Health (NIMH) convened a special conference of over 100 scientists and leaders to outline specific strategies and research initiatives that should be developed to implement the recently released National Plan for Research on Child and Adolescent Mental Disorders.Participants included journal editors, educators from psychology and psychiatry, representatives from private foundations, and leaders of research program areas in public funding agencies. Critical knowledge gaps were identified in five areas of child and adolescent psychopathology, including depression, attention deficit hyperactivity disorder, conduct disorder, the anxiety disorders, and the developmental disorders. For each of these areas, special emphasis was placed on developing new ideas and obtaining critical input from other areas of investigation. This report summarizes the identified research gaps and recommends research initiatives to implement the National Plan, as outlined by the conference participants.     

The influence of personal and family factors on achievement needs and concerns of African-American and Euro-American college women

The relation of personal and family factors to three types of achievement was examined. A sample of 172 African-American and 105 Euro-American women completed four instruments assessing gender role attitudes, daydream achievement, daydream affiliation, n Ach and n Aff, and a demographic profile. Multivariate and univariate analyses of variance showed that African-American more than Euro-American women described themselves as masculine and androgynous and reported more traditional achievement-related daydream activity. Racial differences were also observed for family factors' contributions to gender role attitudes. However, personal variables contributed to gender role attitudes for both groups. Gender role attitudes were also differentially associated with n Ach, daydream achievement, and daydream affiliation. The results are interpreted as support for the continued need to consider structural and cultural influences when investigating women and achievement.     

Event order versus syntactic structure in recall of adverbial complex sentences

Two experiments using recall of sentences examined two contrasting principles of clause ordering in a type of complex sentences: the main-clause-first (syntactic) principle and the event-order (or temporal-causal order) prir ciple. In Experiment 1, these two principles were studied in complex sentences with a main clause and a subordinate adverbial clause-e.g., When she heard the thunder, she stopped playing Frisbee. In sentences of this type the subordinate clause typically describes a temporally or causally antecedent event, while the main clause describes a subsequent event in the temporal-causal sequence. These two principles make opposite predictions on what is the psychologically simpler or preferred order of the two clauses in this type of complex sentence. Results of Experiment 1 showed an overall preference in memory for main-clause-first order. In Experiment 2, complex sentences with a main clause and a subordinate clause not temporally or causally related were also used in a sentence recall task. Similar results were obtained. The implication of these findings for the determinants of linguistic structures was discussed.     

Individual Differences in the Pursuit of Self-Uniqueness Through Consumption

In this paper, we report an original study of the relationships between self-attributed need for uniqueness and several consumer dispositions. The results indicate that the self-attributed need for uniqueness is related to consumers' desires for scarce, innovative, and customized products and to consumers' preferences for unusual shopping venues, but not to consumers' susceptibilities to normative influence. Moreover, we find that these relationships are mediated by a latent variable reflecting individual differences in the tendency to pursue uniqueness through consumption. The theoretical and practical implications of these results are discussed along with directions for future research.     

Cerebral Anesthetization for Localization of Speech: The Contribution of W. James Gardner

In 1949, the neurologist Juhn Wada reported the first use of a new procedure for determining the localization of speech and language in neurological patients: examination of the effects on speech and language after injecting a barbiturate, sodium amytal, into the internal carotid artery of each hemisphere in succession. By the 1960s, Wada'sIntracarotid Amobarbital Procedure,orIAP,had become the method of choice for identifying the speech-dominant side in one kind of neurological patient, persons with epilepsy who are candidates for surgical resection, and it remains so today. In 1941, however, an American neurosurgeon, W. James Gardner, reported his use of a different anesthetization procedure for speech localization in neurological patients. Instead of injecting sodium amytal through the blood supply, as in the IAP, Gardner injected procaine hydrochloride directly into cortical tissue. In this paper, we provide a brief biography of Gardner. We then discuss his method of cortical anesthetization, the theoretical and empirical background guiding his use of this method and his choice of patients, and, finally, the fate of Gardner's method within the scientific community.
