Medical Center ver the past decade, use of androgen deprivation therapy (ADT) to treat prostate cancer has risen seven-fold, from 9.8% of patients in 1989-1992 to 74.6% in 1991-2001 (1). ADT is used as neoadjuvant and adjuvant treatment with radiation therapy (RT), to treat recurrence following primary treatment with surgery or RT, or when the cancer is in an advanced stage at diagnosis. While ADT has demonstrated survival benefits, it also is associated with increases in metabolic and cardiovascular risks. Men receiving ADT have been shown to develop dyslipidemia, decreased arterial compliance, increased insulin resistance, weight gain with increased visceral fat deposition, decreased bone mineral density, decreased libido and erectile dysfunction, fatigue, cognitive changes and depression (1-12)

We review our theory of robust intelligence (RI) for groups. We examine the quality of decisions by groups in the laboratory under either majority rule (MR) or consensus rule (CR). Theoretically, engagement in decision-making becomes a factor depending on whether an individual is in a group or in competition between groups. From earlier research, measures of engagement in three-person groups included self-reports, counts of utterances during discussions, and changes in electro-dermal activity (i.e., galvanic skin responses, or GSR). We predicted engagement (number of utterances) would be greater under CR than MR; under MR, we predicted that GSRs would be greater (more attention). Based on partial analyses, participants under CR spoke significantly more often during discussions than MR. As predicted, after de-trending GSR data, we found MR produced higher GSRs and shorter discussions. Our recent work in group size has increased to five participants working on Wason Selection Tasks.
