Emergence and Human Conduct

Emergence, the occurrence of novel, unpredictable human behavior, is an inherent aspect of human experience on both the individual and collective levels. In this article, we considered the ubiquitous nature emergent events, indicated some of the ways such events manifest themselves, analyzed the personal and inter-personal processes that give rise to them, and suggested some of their implications for psychology and the other social science. Given the inescapable presence of emergence in human conduct, a redefinition of the goals and scope of social science may be desirable.     

Personality Differences Between Stuttering and Non-Stuttering Children as Indicated by the Rorschach Test

Item analyses of the 30-item F Scale in a sample of 355 Ss, and proportionate selection from the nine inferential item clusters first specified for this measure, permitted development of a 15-item version that correlated .95 with the original scale. Application of the shortened version to 194 American and 311 Italian subjects produced nearly equivalent means, but greater variance in the Italian sample. Reliability coefficients were .83 for the American sample and .90 for the Italian. Five items revealed significant differences, interpretable in accordance with known cultural emphases and historical experiences. Testing time for the 15-item scale was approximately five minutes. Complaints about item content were less insistent than typically encountered with the 30-item scale.     

A note on using alpha and stratified alpha to estimate the reliability of a test composed of item parcels

Several authors have suggested that prior to conducting a confirmatory factor analysis it may be useful to group items into a smaller number of item ‘parcels’ or ‘testlets’. The present paper mathematically shows that coefficient alpha based on these parcel scores will only exceed alpha based on the entire set of items if W, the ratio of the average covariance of items between parcels to the average covariance of items within parcels, is greater than unity. If W is less than unity, however, and errors of measurement are uncorrelated, then stratified alpha will be a better lower bound to the reliability of a measure than the other two coefficients. Stratified alpha are also equal to the true reliability of a test when items within parcels are essentially tau‐equivalent if one assumes that errors of measurement are not correlated.     

Extracting the Variance Inflation Factor and Other Multicollinearity Diagnostics from Typical Regression Results

Multicollinearity is a potential problem in all regression analyses. However, the examination of multicollinearity is rarely reported in primary studies. In this article we discuss and show several post hoc methods for assessing multicollinearity. One such multicollinearity diagnostic is the variance inflation factor. We outline the post hoc variance inflation factor method, which computes the variance inflation factor from the standardized regression coefficient and semi-partial correlation, both of which can be calculated from commonly reported regression results. Three examples of computing multicollinearity diagnostics using data from published studies are shown. We conclude with a discussion and practical implications.     

Ethical Challenges for Military Psychologists: When Worlds Collide

Despite the mental health needs in the military and improved access to military psychologists, many in need do not seek psychological services. The military policies, culture, and environment pose considerable barriers to help seeking. In turn, military practices often conflict with the psychologist’s professional ethics, leading to a range of ethical dilemmas including multiple relationships, multiple agencies, and limited confidentiality. To address ethical concerns and encourage service members to seek mental health services, this article proposes maintaining an understanding of military rules, law, and professional ethics; identifying multiple relationships and establishing boundaries up front; and collaborating with the patient in disclosures of information.     

I Can't Wait to Get Married: Gender Differences in Drive to Marry

In this study we examined a new construct—the Drive to Marry (DTM). Young single men and women (149 men and 246 women) rated their desire to get married and completed measures of their valuing of marital, parental, and occupational roles; concern about others' views of them; and feminist attitudes. We found that women had a higher DTM than did men. In both genders, DTM was predicted by the value of parental role and by concern about others' views of them. In women, DTM was also predicted by traditional attitudes toward gender roles, and there was a trend for women who valued the occupational role to have a lower DTM. Conservative women, women who valued the parental role, and women with a higher DTM were also more likely to want to use the title “Mrs.” and to adopt their husband's surname. An earlier version of this paper was presented at the annual meeting of the Midwestern Psychological Association in May 2004.
