“…Some workers [11,14,21,26] investigated the influence of ethanol on DVA with a moving target and a stationary observer. Only one study [16] so far has tested DVA with both observer and target rotating simultaneously.…”

Visual orientation is the most important sensory input during locomotion (e.g. walking, driving a car, riding a bicycle). We investigated dynamic visual acuity (DVA) during vertical body-oscillations (amplitude 5 cm; frequency 1.5 Hz) in 12 healthy subjects before and twice after ethanol consumption. During oscillation, vertical eye movements were recorded under two test conditions: with eyes closed (EC) and during DVA testing. A significant increase in vertical eye-amplitude after ethanol ingestion occurred only during EC tests, as a possible sign of vestibular hyperreaction. During vestibular stimulation alone (EC), ethanol did not affect the phase shift between stimulus and eye movements. However, when the subjects were given an additional visual stimulus (DVA), the post-alcohol phase shift rose significantly. Surprisingly, the post-alcohol phase shift values for the two test conditions showed no significant differences. After ethanol ingestion we found no changes in static visual acuity but a significant loss of DVA. Volunteers with a change of DVA threshold (DVAT) showed significantly (P = 0.004) higher post-alcoholic changes in the phase shift. In summary, low doses of ethanol disturbed the visually guided oculomotor response during fixation of an earth-fixed target while the observer was subject to linear vertical acceleration. This effect led to an increasing delay between the beginning of body and eye movements. The consequence was an increasing phase shift and thus a decrease in DVA during whole-body oscillation which was comparable to movements during human locomotion.

Hate crimes are those in which the victim is selected because of his or her actual or perceived race, color, religion, disability, sexual orientation, or national origin. Hate crime laws have frequently been met with objections. Whereas some objections are based in constitutional law, other objections invoke a variety of psychological constructs, including attitude, motivation, behavior, emotion, and intergroup relations. These objections can be illuminated by relevant psychological theory and research. Topics addressed include the measurement of motivation and intent, and distinctions among attitudes, emotions, and behavior. Hate crimes and other crimes are compared in terms of perpetrators, type and degree of violence, psychological and physical trauma suffered by victims, and community impact. Psychologically based defense strategies used by perpetrators of hate crimes are critiqued. Hate crime laws are also discussed in terms of the political and social values they reflect. Finally, research and policy implications are outlined, including implications for prevention and intervention at the individual, community, and law enforcement levels.
