Relationship between maternal aggression and maternal care in the rat

Aggression among female rats is almost entirely confined to the period of late pregnancy and lactation. Behaviorally it is similar to the aggression of males including piloerection and lateral attacks, but it differs in its function. Unlike male aggression which serves to establish a social hierarchy and a territory, i. e., is competitive, maternal aggression is protective, i. e., it serves to prevent predation of the mother's offspring. In this respect it is closely related temporally and causally to maternal care; if the offspring are removed maternal aggression wanes almost immediately–its function no longer exists! Studies on aggression by mothers, among rats, from the author's laboratory are reviewed and comparisons made with maternal care. As noted, maternal aggression and maternal care are closely related during the cycle of maternal behavior and they share a similar hormonal basis and possibly the effect of uterine stimulation, but maternal care requires prolactin and the decline of progesterone while maternal aggression appears independent of pituitary hormones and does not require a decline in progesterone. Maternal aggression like maternal care appears to be organized into a hormonal phase, during pregnancy, parturition, and for about a week postpartum and a nonhormonal phase thereafter. Bilateral radiofrequency lesions of the lateral midbrain peripeduncular nucleus (PPN) produce deficits in maternal aggression if made on lactation day 7 (L7), but not earlier, without producing significant deficits in maternal behavior. Experiments showed that the PPN does not mediate hormonally stimulated maternal aggression; it appears to mediate only nonhormonally stimulated maternal aggression. Studies on the role of pregnancy hormones on long-term retention of maternal aggression and the role of olfaction in maternal aggression are also reviewed. © 1994 Wiley-Liss, Inc.     

Cognitive-Behavioral Treatment of Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) can be treated effectively with cognitive-behavioral therapy. When working with clients who have GAD, therapy can focus on four central areas that help to promote therapeutic change. The initial focus of therapy is on developing a sound therapeutic alliance and educating the client about anxiety symptoms. Skills training focuses on relaxation training and cognitive changes that can help clients confront their worries in a constructive manner. Then, exposure to internal and external aspects of the anxiety can help clients test and refine their coping skills. Finally, because of the chronic nature of GAD, relapse prevention strategies can be used to help maintain treatment gains over time. These strategies allow a broad but flexible treatment plan that can be adapted to the unique needs of each individual client.     

Orienting versus learning instructions in children's free recall: New evidence

Ninety-six first graders were given a list of either words or pictures to process under three types of incidental orienting instructions (semantic, directed at list organization; semantic, directed at individual item characteristics; and physical) and an intentional-learning instruction. For pictures and words, list organizational instructions were the most effective, and were superior to intentional-learning instructions. In contrast, individual item-orienting instructions were not better than intentional-learning instructions on either list. Additionally, different patterns of instructional effects emerged on the two list types, which were interpreted with respect to both available data and contemporary processing theories.
