The Anger Expression Scale (AX) was administered to 150 volunteers ranging in age from 21 to 83 years. Participants were placed into one of three groups on the basis of their chronological age: Young Adult (21 to 39 years), Middle Age (40 to 59 years) and Old (60 to 83 years). The AX yields three scores, anger-in, anger-out and total AX. Each of the three AX scores was analyzed by a 3 (Age Group) x 2 (Gender of Subject) ANCOVA with educational level as the covariate. Results indicated that the Young Adult Group expressed more anger-out than the Old Group, and both the Young Adult and Middle-Age groups had higher total AX than the Old. No significant main effects were observed for the variable anger-in, and no gender differences were found for any of the three variables. Implications of results are discussed.

The higher rate of injuries, particularly minor injuries, being reported suggests a culture of injury reporting and recording within these supported living services. Electronic injury monitoring is recommended for organizations providing supported living services for adults with intellectual disabilities.

5 male hamsters were reduced to 80% ad lib. weight and were run in a 3-hr. session with a VI-60 sec. schedule for 20-mg. pellets for 14 consecutive days. Water was freely available at all times. As hamsters did not exhibit the excessive drinking characteristic of other animals under similar paradigms, there appears to be a species limitation to schedule-induced polydipsia.The finding of Falk (1961) that rats bar pressing on a VI-60 sec. schedule of food reinforcement would consume almost half of their body weight in water during an approximate 3-hr. session has lead to the investigation of schedule-induced polydipsia in numerous other studies. Among the species in which this phenomenon has been demonstrated are mice (Palfia, et al., A point worthy of note is that rwo animals known to demonstrate scheduleinduced polydipsia have also been shown to decrease their water consumption when food deprived. Verlplank and Hayes (1953) demonscrated that the rat reduced water intake when food deprived. Similarly, Schuster and Woods (1966) reported a reduction of water intake in the rhesus monkey when food deprived. Noc all animals show a reduction in water intake as a function of food deprivation; the hamster (Kutscher, et al., 1968a) and the gerbil (Kutscher, et al., 1968b; VanderWeele BE TeLlish, 1971; Kutscher, 1973) being notable exceptions. Both of these animals often show dramatic increases in water intake when food deprived. Further, both of these animals are primarily desert creatures whereas none of the animals demonstrating schedule-induced polydipsia are.In view of the diversity of animals for which the phenomenon has been demonstrated, the phenomenor, appears rather universal; however, we need to explore whether this phenomenon can be shown for animals which show fooddeprivation polydipsia. The purpose of this study then was to investigate schedule-induced polydipsia in one such animal (Kutscher, et al., 1968a). METHOD Sic6 jectsSs were five male golden hamsters (Masocricefw ui~ratz~s), whose average weight was 127 gm. at the beginning of the experiment. During the experiment Ss were individually housed and maintained on Wayne Lab-Blox rodent chow.'Now at the University of Louisville. Requests for reprints should be sent to W.

10 albino rats were divided into 2 groups and were exposed to a DRL-18-sec. schedule. For one group a block of wood was present for the first 40 days while for the second group no wood was present. Subjects with wood available initially showed more reinforced barpresses primarily due to long interresponse time responses (27+ sec.) and large amounts of collateral wood chewing. After 28 days the two groups were receiving essentially the same number of reinforcements. After 40 days the conditions of wood availability were reversed. The animals with wood now available did not engage in collateral wood chewing, and there was no apparent difference in the performance of the two groups. The results question the hypothesis that collateral activities serve as time-mediational devices.

The State-Trait Personality Inventory was administered to 150 volunteers whose ages ranged from 21 to 83 yr. Participants were placed into one of three groups on the basis of their chronological age: young adults (21 to 39 yr.), middle-age (49 to 59 yr.), and old (60 to 83 yr.). Analysis indicated no significant main effects for age group on any of the six subscales with education statistically controlled. Significant sex differences were found on the Trait Anxiety Scale; women had higher trait anxiety. There was no significant interaction of sex and age. Implications of results were discussed.
