Unconscious gender bias in fame judgments?

In two experiments the conditions of, and the processes leading to, gender biases in fame judgments were investigated. In Experiment 1, the gender bias was not reduced in a condition that alerted participants to the gender of the names. In Experiment 2, participants' sex-role orientation, but not their gender, was related to the gender bias. The process dissociation procedure was used in both experiments in an attempt to separate conscious and unconscious memory processes contributing to the gender bias. Using L.L. Jacoby's 1991) original measurement model there appeared to be evidence for unconscious influences on the gender bias in fame judgments. Unfortunately, this evidence disappeared when a model was used that takes guessing and, hence, response biases into account, which confirms that measurement models that ignore response biases in the process dissociation procedure may lead to erroneous conclusions.

Investigating fame judgments: on the generality of hypotheses, conclusions, and measurement models.

In this article, we try to clarify some of the issues raised by S.C. Draine, A.G. Greenwald, and M.R. Banaji (1996) concerning our investigation into the gender bias in fame judgments (A. Buchner & W. Wippich, 1996). First, we did not test the general hypothesis and did draw the general conclusion that Drain et al. suggest we did. Second, we did did not reject M.R. Banaji and A.G. Greenwald's (1995) assumptions about the familiarity of male and female names in the fame judgment task, but we showed how one could have come to reject it using a widespread measurement model for the process dissociation procedure. Third, we argue that the processes which Draine et al. suggest should also be included in the measurement model we used are probably negligible, and if they are not, then the validity of the results of a number of fame judgment experiments must be called into question. In general, however, we agree with what seems to be the main message of M.R. Banaji and A.G. Greenwald's (1995) research, namely, that social categories have to be considered whenever priming is investigated within a social domain.

Expression of plakoglobin in renal cell carcinoma.

Little is known about the role of molecules involved in cell-cell interactions during the progression of renal cell carcinoma (RCC). We investigated the expression of plakoglobin (a component of the cadherin-catenin adhesion system) in 94 samples of normal kidney tissue from patients with RCC, in 109 primary renal cell carcinomas and in 16 metastases by immunohistochemistry. Expression of plakoglobin was significantly diminished in tumor tissue, particularly in metastatic lesions, as compared to normal kidney tissue (p < 0.001). Follow-up data were available from 87 patients. Patients with a diffuse plakoglobin expression (91-100% positive cells) in primary tumor tissue had a significant better survival rate than patients with a disturbed plakoglobin expression (p < 0.05) as determined by the log rank test. These results indicate that loss of plakoglobin may play an important role in malignant transformation of renal cells. Plakoglobin expression status could give additional information about the individual prognosis.
