Using the microcomputer as a visual aid in the statistics classroom

A microcomputer running a spreadsheet program makes an excellent visual aid for demonstrating statistical concepts and procedures. Some advantages of this setup over traditional visual aids are described. Several statistical demonstrations that I have found to work well are presented.     

Comparing Idiothetic, Ipsative, and Normative Indices of Consistency

ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates     

A Q-methodological study of lesbian identities

A Q-methodological study of lesbian identities is reported, which reveals substantive factors representing identity account clusters explicated as the ‘Personal Fulfilment’ identity, the ‘Special Person’ identity, the ‘Individualistic’ identity, the ‘Radical Feminist’ identity, and the ‘Traditional’ identity. These identities are supported and illuminated by the use of accounts given by the same respondents in tape-recorded interviews and are related to the rather limited previous literature in the field. Further developments in the investigation of accounts of identity are proposed.     

Ethical dilemmas in forensic evaluations

Ethical issues emerging from forensic assessments are addressed from clinical and research perspectives. The relevance of agency, forensic identification, and attitudes toward defendants are explored within the framework of ethical practice. Finally, the ethical role of mental health professionals in the courtroom, the scope and basis of their testimony, and the rendering of conclusory opinions are discussed within a psycholegal context.     

A developmental study of destereotyping and androgynous activity preferences of tomboys,nontomboys, and males

A study of 210 fourth, sixth, eighth, and tenth graders and adults was conducted to determine developmental trends in both destereotyping of traditionally gender-typed activities and preferences for those activities, and to compare activity preferences of tomboys with other females and with males at different ages. Tenth graders destereotyped less than the other age levels. Additionally, female subjects destereotyped traditionally boys' activities more than girls' activities and more than male subjects. Although nontomboys and boys showed a preference for gender-traditional activities, tomboys preferred traditional girls' and boys' activities equally. Self-defined tomboys do not reject traditionally female activities; instead, they expand their repertoire of activities to include both gender-traditional and nontraditional activities. It is suggested that girls who are able to transcend gender-role behavior in childhood may be the ones who will grow into androgynous adult women.     

Manual performance in the cold with gloves and bare hands

Previous research aimed at quantifying and reducing the decrements encountered in performing manual tasks in cold weather has not described the relationships between task characteristics and cold-induced impairments. The amount of decrement and, often times, the optimal means for reducing the decrement, appear to be task-specific. The research reported here is one in a series of studies formulated to explore those relationships. The strategy is to use tasks from the battery developed by Fleishman (1967) to measure the factorially 'pure' abilities needed to perform all manual tasks. 24 U.S. Marines performed this battery of nine tasks across a range of cold temperatures. To determine if the decrement due to wearing gloves might be less than the decrement due to cold hands as the air temperature decreased, performance on the battery of tasks was measured with and without gloves. Only three of the tasks (abilities) were affected by cold temperatures, and the amount of decrement increased as the air temperature decreased. Three tasks deteriorated due to wearing of gloves, two of those affected by cold and one other. Temperature affected performance independently of the glove effect. Half of the subjects did not complete bare-handed testing at -18 degrees C (approximately 20 min.), indicating this is the lower end of the temperature range in which bare-handed performance for more than a few minutes is practical.
