CHILDHOOD SEXUAL ABUSE, CULTURE, AND COPING: A QUALITATIVE STUDY OF LATINAS

The purpose of this study was to articulate a model of how Latinas cope with childhood sexual abuse (CSA) and the ways in which personal and cultural variables influence their coping strategies. Nine women who identified as Latina and as survivors of CSA participated in an in-depth interview. The data were analyzed using a grounded theory methodology. Results suggested that participants' coping efforts were influenced by a variety of cultural factors and that they engaged in a wide range of coping behaviors, all of which served two main functions: (1) seeking relief from negative emotions and (2) protecting one's self from further abuse.     

Multimodal Treatments for Childhood Attention-deficit/Hyperactivity Disorder: Interpreting Outcomes in the Context of Study Designs

The goal of this article was to outline issues critical to evaluating the literature on incremental benefit of multiple effective treatments used together, vs. a single effective treatment, for childhood ADHD. These issues include: (1) sequencing and dosage of treatments being combined and compared; (2) difficulty drawing valid conclusions about individual components of treatment when treatment packages are employed; (3) differing results emerging from measurement tools that purportedly measure the same domain; and (4) the resultant difficulty in reaching a summary conclusion when multiple outcome measures yielding conflicting results are used. The implications of these issues for the design and conduct of future studies are discussed, and recommendations are made for future research.     

Association between intermale aggression and genetically-defined tryptophan hydroxylase activity in the mouse brain

The relationship between the genetically defined intensity of intermale aggression and the activity of brain tryptophan hydroxylase (TPH) has been studied in inbred mice. No association between the enzyme activity and the percentage of aggressive mice (reflecting the predisposition to aggressive reaction) was revealed. However, a significant positive interstrain correlation between brain TPH activity and accumulated attacking time (reflecting fight intensity) was identified. No correlation was found between TPH activity and the accumulated attacking time in segregating F2 (BALB × C57BL) mice. In conclusion, TPH is an important, but not the only factor controlling the intensity of intermale aggression in mice. © 1996 Wiley-Liss, Inc.     

Effect of MAO A deficiency on different kinds of aggression and social investigation in mice

Monoamine oxidase A (MAO A) degrades serotonin, dopamine and noradrenaline, factors critically involved in the regulation of aggression. Different kinds of aggression were investigated in Tg8, a transgenic mouse strain lacking a functional MAO A gene. MAO A-deficient mice differ from wild-type C3H/HeJ (C3H) in terms of showing higher territorial, predatory and isolation-induced aggression. Tg8 demonstrated shorter latencies to cricket killing and to the first attack after 6 weeks isolation than C3H mice. In the resident-intruder paradigm, MAO A-lacking mice were more aggressive than C3H when tested as intruders. In contrast to C3H, attack in Tg8 mice did not depend on different aggressiveness of intruders of BALB/c, A/Sn and C3H strains. Tg8 mice displayed no increase in aggression but demonstrated reduced social investigation towards anesthetized, as well as towards juvenile BALB/c males. Thus, MAO A deficiency in Tg8 mice is accompanied by increased expression of different kinds of aggression, as well as by disruption of normal pattern of social interaction.

Role of 5HT1A receptors in a variety of kinds of aggressive behavior in wild rats and counterparts selected for low defensiveness towards man

The 5HT_1A receptor agonist ipsapirone (10 mg/kg) suppressed shock-induced aggression in wild and domesticated rats but did not affect predatory aggression in either group of animals. Ipsapirone decreased neophobia and inhibited defensive reactions by wild rats towards man in the glove test. [³H]8-OH-DPAT binding, which labels 5HT_1A receptors, was significantly increased in the hypothalamus of domesticated rats in comparison with wild counterparts, while 5HT_1A density was unchanged in the frontal cortex in domesticated animals. In essence, the aggressive reactions contributing to the defensive behavior complex in wild rats appear to be regulated through 5HT_1A receptors. © 1992 Wiley-Liss, Inc.     

Generating Relations Elicits a Relational Mindset in Children

Relational reasoning is a hallmark of human higher cognition and creativity, yet it is notoriously difficult to encourage in abstract tasks, even in adults. Generally, young children initially focus more on objects, but with age become more focused on relations. While prerequisite knowledge and cognitive resource maturation partially explains this pattern, here we propose a new facet important for children's relational reasoning development: a general orientation to relational information, or a relational mindset. We demonstrate that a relational mindset can be elicited, even in 4‐year‐old children, yielding greater than expected spontaneous attention to relations. Children either generated or listened to an experimenter state the relationships between objects in a set of formal analogy problems, and then in a second task, selected object or relational matches according to their preference. Children tended to make object mappings, but those who generated relations on the first task selected relational matches more often on the second task, signaling that relational attention is malleable even in young children.     

Serotonin's influence on predatory behavior of highly aggressive cba and weakly aggressive DD strains of mice

The effects of serotonin were studied on locust-killing behavior of mice from low (DD) and high (CBA) predatory aggressive strains. 5-HTP injected intraperitoneally (50 and 100 mg/kg) or 5-HT administered into the lateral ventricle (10 μg) significantly reduced locust-killing behavior in highly aggressive CBA mice. Imipramine (20, 30, and 40 mg/kg) elicited a dose-dependent inhibitory effect on predatory behavior. Fluoxetine (10 and 20 mg/kg) alone had a slight influence on locust-killing behavior but potentiated the action of the subthreshold dose of 5-HTP (25 mg/kg). Pretreatment with the blocker of 5-HT₂ type receptors methysergide (2 mg/kg) abolished the inhibitory effect of 5-HTP. These finding indicate that serotonin of the brain exerts an inhibitory effect on predatory behavior in mice. In contrast, neither lesion of the dorsal raphe nucleus (although significantly depleting the brain serotonin) nor treatment with methysergide (2 mg/kg) induced locust-killing behavior in weakly aggressive DD mice. Low predatory aggressiveness in DD mice is suggested to be related to the low tonus of the mechanisms activating killing behavior rather than to excessive serotonergic inhibitory influences.
