ABSTRACT
This work presents the results of a demographic analysis of 30 years of breeding records from the University of Washington's recently closed Primate Field Station at Medical Lake, Washington. Summaries of population growth, age-specific fertility and mortality rates, first-year survival, and seasonality of reproduction are presented, as well as an analysis of survival by decade. In addition, we present data on interbirth intervals in this population. In general, pigtailed macaques represent a typical Old World monkey pattern of age-specific fertility and mortality, with a few minor exceptions. We suggest that pigtailed macaques are most similar to rhesus and Barbary macaques, and that Japanese and bonnet macaques differ somewhat in their demographics.

We present a retrospective analysis of 30 years of breeding records from a colony of pigtailed macaques at the University of Washington's Regional Primate Research Center, specifically examining the effects on pregnancy outcome of sire presence, presence of other pregnant females, group stability, overall group size, and dam age and parity. Data on 2,040 pregnancies (1,890 live births) of socially housed pigtailed macaques (Macaca nemestrina) were obtained from the Washington Regional Primate Research Center's animal colony records from 1967 to 1996. Our results suggest that the presence of the sire and other pregnant females, fewer moves, and lower parity increases the probability of a viable birth. In viable and nonviable births, gestation length was positively related to contact with the sire and other pregnant females, number of moves, and dam age. Once the effect of gestational age was taken into account, birthweight increased with increasing parity and decreased with dam age. Clinical treatment of the dam decreased as sire presence and group size increased and number of moves decreased. The length of treatment was dependent on the number of moves experienced by the dam, with more moves associated with longer treatments. Sire presence was the single most important factor in nearly all measures of reproductive outcome.

Sets of verbal and nonverbal memory tests were subjected to a factor analysis, and the factor composite scores were used to discriminate between 57 brain-damaged and 34 non-brain-damaged subjects. The derived factors clearly represented verbal and nonverbal factors. The brain-damaged group performed significantly less well on both the verbal and nonverbal factor composite scores. It is suggested that a battery of verbal and nonverbal scales be used to discriminate left and right lateralized brain-damaged patient groups.

The study examined the construct-related validity of a 13-item short form of the Marlowe-Crowne Social Desirability Scale advanced by Reynolds (1982), using the validity scales of the MMPI. With a sample of 481 Basic Military Trainees, the short form of the Marlowe-Crowne replicated the correlations between the standard Marlowe-Crowne and the MMPI validity scales initially reported by Crowne and Marlowe (1960). The results further support the short form of the Marlow-Crowne Social Desirability Scale as an economical measure of social desirability.
