Attachments,gender, and delinquency

The purpose of this study is to contribute to a gender‐integrated theory of delinquent behavior by testing the assumptions of gender specialized delinquent behavior and of sex typed bonds as inhibitors of deviance. Data from self‐administered questionnaires completed by a sample of teenagers in the 10th grade and one year later were used in the study. We found no clear evidence of gender specialization in the deviant behavior reported by the youth. Furthermore, the analysis did not lend support to traditional theories that link male and female delinquency to the weakening of different bonds. The testing of an inclusive model of bond theories produced very similar results for both genders.     

The Role of Religion on the Health Practices of Mexican Americans

Twenty million Mexican Americans live in the U.S. (U.S. Census 2000 Summary File, 2000). It is vital that health care clinicians become familiar with and acknowledge the role of religion or religiosity on the health practices of Mexican Americans so that these needs may be addressed through holistic care. This paper reviews the origin and role that religion plays in the health practices of Mexican Americans. The potential benefits of addressing these client’s religious needs are examined and suggestions are offered on how health care clinicians may address these needs in a culturally sensitive manner.Josefina Lujan, MSN, RN is a first generation Mexican American who has been practicing nursing for 25 years in the Texas-Mexico border community of El Paso, Texas.Howard Campbell is an associate professor of anthropology at the University of Texas at El Paso. e-mails: jlujan1@utep.edu; hcampbel@utep.edu     

Differences in the demographic and sociopsychological profile of ROTC vs Non-ROTC students

The demographic and sociopsychological profile of 102 high school and 754 college Army ROTC cadets was compared and contrasted against that of their non-ROTC classmates. The ROTC students were found to differ from their classmates in military background, academic aptitude, personal values, attributes sought in a job, political position, bureaucratic tendencies, and other socio-psychological characteristics. These differences grew larger with time, as progressively older samples of cadets and noncadets were studied. Because of the cross-sectional nature of the present study, it was not possible to determine the extent to which these widening differences were due to: (a) selection differences present at the moment of entry into ROTC; (b) attrition from the ROTC group of cadets with a “deviant” profile; and/or (c) actual changes in cadets brought about by exposure to a military career. Nevertheless, these findings point to the possible existence of a “military personality” that is evident at early career development stages and even among ROTC civilians supposed to provide a “leavening” effect on the United States military.     

Gender roles in relation to assertiveness and eysenckian personality dimensions: Replication with a spanish population sample

The objective of the present study was to evaluate the cross-national replicability of the usual pattern of associations observed in Anglo-Saxon samples between masculinity and femininity on the one hand and difficulty and distress in assertiveness and the major Eysenckian dimensions of personality on the other hand. Participants were 925 SpanishSs (54% females; and 95.5% “European or other white”). Both the masculinity theory of psychological well-being and the notion thathigh femininity would not be implicated in self-assessed psychologicaldistress ordysfunction were supported by the data. Higher-order analysis showed that masculinity loaded highly on Positive Affect, whereas femininity had its primary loading on Constraint. Tentative support was found for the femininity-humility hypothesis advanced by P. B. Zeldow, S. R. Clark, and D. C. Daugherty in 1985.     

BDNF reverses the CTA memory deficits produced by inhibition of protein synthesis

Brain-derived neurotrophic factor (BDNF) is an essential protein synthesis product that has emerged as one of the most potent molecular mediators of not only central synaptic plasticity, but also behavioral interactions between an organism and its environment. Our previous studies on the insular cortex (IC), a region of the temporal cortex implicated in the acquisition and storage of conditioned taste aversion (CTA), have demonstrated that intracortical microinfusion of BDNF induces a lasting potentiation of synaptic efficacy in the projection from the basolateral nucleus of the amygdala (Bla) to the IC of adult rats in vivo. Recently, we found that intracortical microinfusion of BDNF previous to CTA training enhances the retention of this task. In this work, we present experimental data showing that acute intracortical delivery of BDNF (2 microg/2 microl per side) reverses the deficit in CTA memory caused by inhibition of insular cortex protein synthesis due to anisomycin administration (100 microg/microl per side) in male adult Wistar rats. These findings suggest that BDNF is a protein synthesis product essential for neocortical long-term memory storage.     

Unmitigated communion and health among adolescents with and without diabetes: the mediating role of eating disturbances

The authors examined the implications of unmitigated communion--a focus on others to the exclusion of the self--for psychological and physical health among adolescents with (n = 132) and without (n = 131) diabetes times/during a 1-year period. Unmitigated communion predicted greater psychological distress and lower levels of competence cross-sectionally and longitudinally, controlling for sex, pubertal status, and communion. Health status moderated some longitudinal relations, such that relations held only for adolescents with diabetes. In addition, unmitigated communion was associated with poor metabolic control and predicted a deterioration in metabolic control over the year for adolescents with diabetes. Unmitigated communion also was associated with disturbed eating behavior cross-sectionally and longitudinally, and disturbed eating behavior explained some of the relations of unmitigated communion to psychological but not physical health outcomes.     

Anxiety sensitivity and panic symptomatology: the mediator role of hypochondriacal concerns

The present study tests the mediating role of hypochondriasis to explain the relation between anxiety sensitivity and panic symptomatology. Fifty-seven outpatients with clinically significant levels of panic symptomatology were selected to participate in the study. Measures of anxiety sensitivity, hypochondriasis, and panic symptomatology were obtained from standardized, self-administered questionnaires: the Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), the Whiteley Index of Hypochondriasis (WI; Pilowsky, 1967), and the Panic-Agoraphobic Spectrum Self-Report (PAS-SR; Cassano et al., 1997; Shear et al., 2001). Regression analyses were performed to test for the mediation models. The results show that the effect of anxiety sensitivity on panic symptomatology is not significant when controlling the hypochondriacal concerns, whereas the latter predicted panic symptoms. This result holds for the overall ASI as well as for the Physical Concerns and the Mental Incapacitation Concerns dimensions of the ASI scale. No evidence of a direct relation between the Social Concerns dimension and panic symptoms was found. The findings suggest that hypochondriacal concerns might represent the mechanism through which anxiety sensitivity is able to influence panic symptoms.     

Power in methods: language to infants in structured and naturalistic contexts

Methods can powerfully affect conclusions about infant experiences and learning. Data from naturalistic observations may paint a very different picture of learning and development from those based on structured tasks, as illustrated in studies of infant walking, object permanence, intention understanding, and so forth. Using language as a model system, we compared the speech of 40 mothers to their 13‐month‐old infants during structured play and naturalistic home routines. The contrasting methods yielded unique portrayals of infant language experiences, while simultaneously underscoring cross‐situational correspondence at an individual level. Infants experienced substantially more total words and different words per minute during structured play than they did during naturalistic routines. Language input during structured play was consistently dense from minute to minute, whereas language during naturalistic routines showed striking fluctuations interspersed with silence. Despite these differences, infants' language experiences during structured play mirrored the peak language interactions infants experienced during naturalistic routines, and correlations between language inputs in the two conditions were strong. The implications of developmental methods for documenting the nature of experiences and individual differences are discussed.     

Proactive interference between cues trained with a common outcome in first-order Pavlovian conditioning

The nature of interference between cues (X, A) trained apart with a common outcome (O; an unconditioned stimulus) was explored by assessing proactive interference in first-order Pavlovian conditioning (i.e., A-O, X-O, resulting in attenuated responding to X). Three lick-suppression studies were conducted with water-deprived rats. Posttraining extinction of the interfering cue (A) attenuated proactive interference (Experiment 1), which mirrors the observation that extinction of the competing cue can reduce competition between cues trained together (e.g., recovery from overshadowing). Proactive interference was also attenuated with manipulations known to attenuate interference between outcomes trained apart (e.g., counterconditioning), namely reminder cues (Experiment 2) and renewal (Experiment 3). The findings suggest that similar processes underlie interference between cues trained apart, between cues trained together, and between outcomes trained apart.     

The role of cortical cholinergic pre- and post-synaptic receptors in taste memory formation

A number of studies have implicated cholinergic activity in the mediation of learning and memory processes. However, the specific role of muscarinic receptors in memory formation mechanisms is less known. The aim of the present study is to evaluate the effects of muscarinic antagonist M2 presynaptic receptor, AFDX-116 (0.5mM) and M1 and M3 post-synaptic receptor pirenzepine (100mM), as well as a non-selective muscarinic antagonist, scopolamine (136mM), in the insular cortex (IC) during acquisition and retrieval of conditioned taste aversion (CTA). In addition, we evaluate the effects of those antagonists in cortical ACh release by in vivo microdialysis and the effects on the induction of in vivo LTP in the BLA-IC projection. The results showed that the cortical microinjections of scopolamine and pirenzepine, but not AFDX-116, produced significant disruption in the acquisition of CTA, without effects during retrieval. Microinjections of scopolamine and AFDX-116 produced significant cortical ACh release, while infusions of pirenzepine did not produce any release. Application of scopolamine and pirenzepine diminished induction of LTP in the BLA-IC projection, but not AFDX-116, as compared with vehicle. The induction of BLA-CI LTP seems to be modulated by post-synaptic muscarinic acetylcholine receptors and not by pre-synaptic muscarinic receptors. These results suggest a differential involvement of cholinergic receptors during acquisition and retrieval of aversive memory formation, as well as a differential role of muscarinic receptors in the biochemical and electrophysiological processes that may underlay aversive memory.
