We investigated the possibility that a range of social stimuli capture the attention of 6-month-old infants when in competition with other non-face objects. Infants viewed a series of six-item arrays in which one target item was a face, body part, or animal as their eye movements were recorded. Stimulus arrays were also processed for relative salience of… (More)
Pretreatment with AMPT at doses which markedly altered the self-injection or amphetamine did not affect the self-injection of apomorphine. These data support the idea that the self-injection of apomorphine is produced via the direct activation of dopamine receptors rather than by the release of either norepinephrine or dopamine.
Lorazepam reduced conflict behavior in rats and monkeys, inhibited pentylenetetrazol- and electroshock-induced convulsions, suppressed footshock-induced fighting behavior, and prevented morphine-induced stimulation in mice at lower doses than other benzodiazepines tested. This behavioral profile suggests that lorazepam will be an active anti-anxiety agent… (More)
