Three studies extended laboratory research on aggression to a naturalistic setting which involved horn honking from drivers as a measure of aggression; the studies were adapted from Doob and Gross. The results from a survey (Study 1) of 59 drivers suggested that they were frequently irritated by and aggressive toward other drivers. A second study (using a 3 X 2 factorial design with 92 male drivers) indicated that manipulations of a rifle in an aggressive context and victim visibility (dehumanization) both significantly influenced horn honking rates subsequent to obstruction at a signal light. A third study with 137 male drivers and 63 female drivers examined the interactive effects of a rifle, an aggressively conno'tated bumper sticker, and individual subject characteristics (sex and an exploratory index of self-perceived status) on horn honking. The results for three studies in naturalistic settings offer possible extensions of laboratory based findings on aggression. The role of inhibitions in modifying the pattern of results was also discussed.

Weber and Cook suggested that evaluation apprehension and subject sophistication are powerful determinants of behavior in the laboratory but that much of the evidence concerning subject sophistication (deception and/or demand awareness) has been confounded with evaluation apprehension, In the present study, there was an experimental manipulation in a 3 X 2 design of three levels of subject sophistication and two levels of evaluation apprehension in an otherwise close replication of the seven-shock-unassociatedweapons condition from Berkowitz and LePage. A seventh condition replicated the procedures of their seven-shock-no-weapons condition. Eleven male university students were run in each condition. The results indicated that increased levels of both evaluation apprehension and subject sophistication led to decreased numbers of shock administered by subjects to their frustrators. The findings were interpreted as suggesting that the most naive and unsophisticated subjects should be used in laboratory studies of aggression so that inhibitions do not mask the effects of important independent variables.

Measures of positive and negative events were derived from a life-event inventory to test the predictions of an equilibrium model and a positive mental health model of psychological well-being. These measures were related to indicators of individual and community well-being with data obtained through a household survey of 454 residents. Residents who reported more negative events also reported more psychological distress and less positive adjustment. Positive events were associated with reports of positive adjustment. An analysis of census tract scores on life events revealed that the relative absence of positive events in census tracts was associated with higher service utilization rates to the community mental health center serving those tracts. The number of negative events was unrelated to service rates for census tracts but was related to several demographic indicators of well-being.

Evidence is presented suggesting that firearms violence is an important social problem. Research strongly suggests that the effectiveness of firearms as a cause of death and injury may be due to their widespread availability, their lethality, and the impulsivity of their use. The investigation of a possible causal link between firearms and impulsive aggression led to Berkowitz and LePage's (1967) weapons effect experiment. The results suggested that weapons can increase the instigation to aggression in aroused an uninhibited individuals. The researchers reasoned that weapons might stimulate aggression by classical conditioning processes resulting from learned associations between aggressive acts and weapons. Although a few studies have failed to reproduce an aggression‐enhancing effect of weapons, the original finding has been replicated in several countries with diverse subject groups both in field and laboratory settings. However, these studies also indicate that many individuals may react with anxiety or fear in the presence of weapons and inhibit aggressive reactions. Manipulations of evaluation apprehension, subject suspiciousness, and/or hypothesis awareness about the purpose of the weapons in the experiments all seem to lead to reduced levels of aggressive response in the presence of weapons. These findings offer a possible explanation for the few failures to replicate the original weapons effect; if researchers used apprehensive subjects or subjects who were aware of possible experimental deceptions, they were more likely to observe an inhibitory reaction rather than an aggression‐enhancing effect of weapons.

Privatization has received significant attention in the popular and professional press. The notion has gained increasing political acceptance with the private sector being seen as cost-effective, innovative, and responsive. Private mental health initiatives will grow because the private sector is seen as an efficient allocator of resources and because there are profit opportunities in traditionally public services. However, a partnership between the private and public sectors will be required in planning and development, serving difficult groups, and defining and measuring quality of care.
