Our goal in this paper is to examine the potential origins of children's understanding of morally relevant transgressions, with a particular focus on how children's perceptions of both proximal and distal unfairness might influence their social reasoning and behavior. A preliminary theoretical model is presented that addresses connections among aggressive children's social cognitive biases, their attachment histories, and their working models of societal justice and fairness. It is argued that difficulties in early parent–child interactions in combination with hostile larger social environments act to undermine emotional reciprocity, empathy, and concern for others in ways likely to promote proactive, uncaring forms of victimization and harm. Furthermore, it is proposed that given sufficiently toxic social experiences, some children will develop beliefs that life does not primarily revolve around caring or fairness, but around power and domination. Discussion focuses on the potential implications of these non-normative but coherent moral beliefs for theory and intervention.  相似文献

This paper addresses one aspect of the natural law theory of Germain Grisez. According to Grisez, practical reason identifies the goods of human life prior to the invocation of any moral or normative notions. It can thus provide a non-normative foundation for moral theory. I present Grisez’s position and argue that the apparently non-normative aspect of natural law cannot support the moral position built upon it. I argue, in particular, that practical principles, as Grisez understands them, are best understood as speech acts. If this is correct, it is possible to develop a sceptical challenge to Grisez’s position. I am grateful to Michael Frede, Robert George, Richard Holton, Philip Pettit, and two anonymous reviewers for many helpful comments on this paper. This paper was presented at a seminar in the Department of Philosophy at Princeton University in November 1987, and I am grateful for the comments I received from the audience—in particular, Germain Grisez—on that occasion.  相似文献

ABSTRACT— Childhood maltreatment elevates risk for antisocial behavior, depression, and other problems over the life span, but a subset of maltreated individuals avoids maladaptive development and shows resilience. Resilience reflects a dynamic confluence of factors that promotes positive adaptation despite exposure to adverse experiences. Recent replicated findings of gene–environment interactions (abbreviated G × E) involving maltreatment have identified two genes, monoamine oxidase A ( MAOA ) and serotonin transporter ( 5-HTT ), that moderate the association between childhood maltreatment and psychopathology. Accordingly, G × E raise new questions about potential biological mechanisms by which some individuals are able to cope adaptively and function relatively well despite experiencing early adversity. We summarize advances toward greater specification of G × E mechanisms, including genetic and environmental moderation of G × E effects and imaging genomics that provide clues regarding resilience processes in development.  相似文献

Intra-amygdala injections of anisomycin produce large increases in the release of norepinephrine (NE), dopamine (DA), and serotonin in the amygdala. Pretreatment with intra-amygdala injections of the β-adrenergic receptor antagonist propranolol attenuates anisomycin-induced amnesia without reversing the inhibition of protein synthesis, and injections of NE alone produce amnesia. These findings suggest that abnormal neurotransmitter responses may be the basis for amnesia produced by inhibition of protein synthesis. The present experiment extends these findings to the hippocampus and adds acetylcholine (ACh) to the list of neurotransmitters affected by anisomycin. Using in vivo microdialysis at the site of injection, release of NE, DA, and ACh was measured before and after injections of anisomycin into the hippocampus. Anisomycin impaired inhibitory avoidance memory when rats were tested 48 h after training and also produced substantial increases in local release of NE, DA, and ACh. In an additional experiment, pretreatment with intrahippocampal injections of propranolol prior to anisomycin and training significantly attenuated anisomycin-induced amnesia. The disruption of neurotransmitter release patterns at the site of injection appears to contribute significantly to the mechanisms underlying amnesia produced by protein synthesis inhibitors, calling into question the dominant interpretation that the amnesia reflects loss of training-initiated protein synthesis necessary for memory formation. Instead, the findings suggest that proteins needed for memory formation are available prior to an experience, and that post-translational modifications of these proteins may be sufficient to enable the formation of new memories.A dominant view of the molecular basis for memory is that the formation of long-term memory for an experience depends on de novo protein synthesis initiated by that experience (Davis and Squire 1984; Frey and Morris 1998; Kandel 2001; Dudai 2002; Nader 2003; Alberini 2008). This view is supported by numerous studies showing that drugs that interfere with protein synthesis by inhibiting translational processes near the time of training produce later amnesia.Despite the centrality of experience-induced protein synthesis in contemporary models of memory formation, the necessity of protein synthesis for memory consolidation and long-term potentiation (LTP) stabilization has been questioned since the beginning of experiments of this type (e.g., Flexner and Goodman 1975; Barraco and Stettner 1976; Flood et al. 1978; Martinez et al. 1981), and continues to be questioned in several recent reviews (Routtenberg and Rekart 2005; Gold 2006, 2008; Radulovic and Tronson 2008; Routtenberg 2008; Rudy 2008). There are many instances of intact memories formed in the presence of extensive inhibition of protein synthesis, and a wide range of behavioral and pharmacological manipulations can rescue memory impaired by protein synthesis inhibitors. For example, amnesia is attenuated in a graded manner by increasing the training trials and foot shock intensity in avoidance tasks (Flood et al. 1975, 1978). Moreover, a wide range of stimulants, such as amphetamine, strychnine, corticosteroids, and caffeine, block amnesia induced by anisomycin (Flood et al. 1978). Like memory, LTP is sometimes insensitive to protein synthesis inhibitors. Simultaneous inhibition of both protein synthesis and degradation does not interfere with induction and maintenance of LTP (Fonseca et al. 2006a). Also, the specific schedule and frequency of test pulses after induction of LTP determine the vulnerability of LTP to anisomycin-induced impairment; anisomycin treatment does not impair LTP unless test pulses at a rate of 1/10 sec were administered during the anisomycin exposure (Fonseca et al. 2006b).Findings that memory and LTP can survive the inhibition of protein synthesis challenge the necessity of specific training- or stimulation-initiated protein synthesis for memory formation and synaptic plasticity. Several actions of protein synthesis inhibitors offer alternative accounts for amnesia produced by these drugs. These include cell sickness (Rudy et al. 2006; Rudy 2008), activation of protein kinases and superinduction of immediate early genes (Radulovic and Tronson 2008), abnormal neural electrical activity (Agnihotri et al. 2004; Xu et al. 2005), and intrusion of neural “noise” that masks the primary changes representing memory formation (Gold 2006). Neural responses to inhibition of protein synthesis such as these may impair memory either secondary to or independent of interference with protein synthesis.Another example of the mechanisms by which inhibition of protein synthesis might impair memory is by altering neurotransmitter functions. This possibility was suggested in early studies (e.g., Flexner and Goodman 1975; Quartermain et al. 1977) and has recently been supported by studies of neurotransmitter release at the site of intra-amygdala injections of anisomycin (Canal et al. 2007). In addition to impairing later memory after inhibitory avoidance training, pretraining injections of anisomycin into the amygdala produced rapid and dramatic increases in release of norepinephrine (NE), dopamine (DA), and serotonin (5-HT) at the sites of injection. The release of NE and DA then plummeted below baselines from 2 to 6 h after anisomycin injections, recovering within 48 h after anisomycin injection. The possibility that these neurochemical changes contribute to anisomycin-induced amnesia was supported by studies showing attenuation of amnesia in rats pretreated with intra-amygdala injections of the β-adrenergic receptor antagonist propranolol, apparently acting to blunt the effects of the large increases in release of NE after anisomycin injection. In addition, amnesia was produced by injections of high doses of norepinephrine into the amygdala.In addition to amnesias produced by anisomycin injections into the amygdala, as above, anisomycin also impairs memory when administered to other memory systems, including the hippocampus, where anisomycin impairs inhibitory avoidance memory (Quevedo et al. 1999; Debiec et al. 2002; Milekic et al. 2006). The present study extends the prior findings (Canal et al. 2007) in several respects. Experiments presented here determine whether anisomycin injections into the hippocampus result in changes in release of the catecholamines, NE and DA, at the site of injection, as seen previously in the amygdala. Additionally, the present experiments determine whether intrahippocampal injections of anisomycin result in increased release of acetylcholine, a neurotransmitter not examined in the previous study. To examine parallels with earlier amygdala findings, a further experiment determines whether intrahippocampal pretreatment with propranolol is effective in attenuating anisomycin-induced amnesia.  相似文献

There is a need to investigate exactly how memory breaks down in the course of Alzheimer’s disease (AD). Examining what aspects of memorial processing remain relatively intact early in the disease process will allow us to develop behavioral interventions and possible drug therapies focused on these intact processes. Several recent studies have worked to understand the processes of recollection and familiarity in patients with mild cognitive impairment (MCI) and very mild AD. Although there is general agreement that these patient groups are relatively unable to use recollection to support veridical recognition decisions, there has been some question as to how well these patients can use familiarity. The current study used receiver operating characteristic (ROC) curves and a depth of processing manipulation to understand the effect of MCI and AD on the estimates of recollection and familiarity. Results showed that patients with MCI and AD were impaired in both recollection and familiarity, regardless of the depth of encoding. These results are discussed in relation to disease pathology and in the context of recent conflicting evidence as to whether familiarity remains intact in patients with MCI. The authors highlight differences in stimuli type and task difficulty as possibly modulating the ability of these patients to successfully use familiarity in support of memorial decisions.  相似文献

This study explored the relations among internalized homophobia (IH), experiential avoidance, and psychological symptom severity in a community sample of 72 lesbian sexual assault survivors. Results indicated that IH is associated with both experiential avoidance and posttraumatic stress disorder (PTSD) symptom severity. In addition, experiential avoidance is related to both PTSD and depression symptom severity. Finally, experiential avoidance completely mediated the relation between IH and PTSD symptom severity. The implications of these findings are discussed and suggestions for future research are provided.  相似文献

This study was designed to investigate the role of emotional awareness and expressiveness as influences on the experience of burden and impaired health for women and men maintaining a spouse or relative at home who had been diagnosed as having dementia. One hundred and thirty-one Caucasian care givers, 41 males and 90 females, participated in the study. Multivariate analysis of variance indicated that women scored higher than men on measures of burden, health complaints, and awareness of others' emotions. Regression analysis indicated that self-awareness of emotions interacted with care-giver gender to decrease health complaints for female care givers but increased health complaints for male care givers. Self-awareness of emotions also increased feelings of burden for male care givers in general and for female care givers experiencing low levels of burden. Awareness of others' emotions tended to reduce feelings of burden. Emotional expressiveness did not influence burden or health complaint scores.This research was funded by grants from the Health Research Funds of Quebec, the Quebec Council for Social Research, and the Montreal Alzheimer Society. The authors would like to express their gratitude to Valerie Takeda, Charlene Stamegna, and Helene Fyfe for their work on the project, and to the families, patients, and staff of the various referral agencies for their cooperation with the study.To whom reprint requests should be addressed at Centre for Research in Human Development, Concordia University, 1455 de Maisonneuve Boulevard West, Montreal, Quebec, Canada, H3G 1M8.  相似文献

A fundamental function of the therapeutic frame is protection of the therapeutic process from the intrusion of elements antithetical to the best interest of the client and detrimental to treatment outcome. It is argued that dogmatic interpretation of the frame promotes conformity rather than growth in the client, blinds the therapist to legitimate issues of client diversity, and constricts the therapist's ability to be appropriately responsive to the client. It is suggested that while the frame is essential to maintain the focus of treatment on the welfare of the client, inflexible adherence undermines this purpose.  相似文献

The hypothesis that psychosocial contextual factors contribute to developmental changes in memory was examined using 326 male World War II veterans. Availability of young adult intelligence scores made it possible to separate the contributions of contextual variables and age to maintenance of general intelligence from their direct contributions to performance on 4 memory tasks. Being younger, healthier, more educated, more introverted, more intellectually active, and more satisfied with social support predicted less intellectual decline and, indirectly, better memory performance. Age, personality, locus of control, and extent of social support directly contributed to performance on 1 or more memory tasks. Age contributions were consistent with Craik's (1986) proposed continuum of task demands for self-initiated effort. Possible elaborations of Craik's hypothesis to accommodate contextual variables are suggested.  相似文献

This experiment determined whether centrally administered glucose can attenuate scopolamine-induced deficits in spontaneous alternation performance. All rats were surgically prepared with indwelling cannulae directed at the lateral ventricle. Thirty min prior to alternation tests, rats received systemic (ip) injections of saline or scopolamine (3 mg/kg). Ten or thirty min prior to training, the rats also received a direct injection into the lateral ventricle of either artificial cerebrospinal fluid (CSF) or glucose (3 micrograms in 1 microliter). Scopolamine significantly impaired spontaneous alternation performance relative to controls. Additional treatment with ICV glucose 30 min, but not 10 min prior to testing, significantly attenuated the scopolamine-induced deficit. These results add support to the view that glucose acts directly on brain systems to attenuate behavioral effects of cholinergic antagonists.  相似文献
