The discursive explosion that was provoked by the new genetics could support the impression that the ethical and social problems posed by the new genetics are somehow exceptional in their very nature. According to this view we are faced with special ethical and social problems that create a challenge so fundamental that the special label of genethics is needless to justify. The historical account regarding the evolution of the gene concepts could serve us to highlight the limits of what we know about genes and what we can do with genes. The widespread notion about the exceptionality of genetic knowledge and its applicative possibilities is hardly justifiable and leads to misunderstandings regarding the conceptualization of the ethical and social problems we might face. Following a more realistic interpretation of the role of genes in human life we might avoid a whole set of fictive dilemmas and counterproductive regulatory efforts in bioethics. Bioethical discourse should move from the gene-centered scientific discourse toward the more sophisticated and complex discourses where human development represented as a matter of complex interactions between genomes and environments, between genes, educational factors, nutritional regimes, and other different developmental resources. If a gene is seen as one among the different developmental resources that are shaping a given human trait then both genethics and genetic exceptionalism could hardly be represented as a justified approach in discussing the ethical and social problems of genetics. 相似文献

The Code of Ethics (COE) of the National Society of Genetic Counselors (NSGC) was adopted in 1992. In 2004, the NSGC leadership appointed the Code of Ethics Work Group (COEWG) to consider revisions to the NSGC COE based on advice from the NSGC legal counsel, and to consider additional changes given growth in the scope of genetic counseling practice since the adoption of the original COE. After input from the NSGC membership, changes to the COE addressing the recommendations of the NSGC legal counsel were approved in December 2004. The COEWG then reviewed ethical codes and codes of professional conduct from 22 professional organizations, deemed to have similar goals and philosophies to the NSGC, searching for themes that encompassed genetic counseling practice that might not yet be addressed in the NSGC COE. Additional revisions to the COE were proposed, and after feedback from the NSGC membership, the revised COE was approved in January 2006 by majority vote of full members of the NSGC. The explications for the 2004 and 2006 revisions are presented. 相似文献

Cognitive models implicate interpretation bias in the development and maintenance of obsessive compulsive and related disorders (OCRDs), and research supports Cognitive Bias Modification for Interpretation (CBM-I) in targeting this mechanism. However, prior studies in OCRDs have been limited to nonclinical populations, adolescents, and adults in a laboratory setting. This study evaluated the feasibility and acceptability of CBM-I as an adjunctive intervention during intensive/residential treatment (IRT) for adults with OCRDs. We modified a lab-based CBM-I training for adults seeking IRT for OCRDs, and conducted a feasibility trial (N = 4) and subsequent pilot RCT; participants (N = 31) were randomized to receive CBM-I or psychoeducation. Benchmarks were met for feasibility, acceptability, and target engagement. From pre- to post-intervention, the CBM-I group showed a large effect for change in interpretation bias (d = .90), whereas this effect was trivial (d = .06) for psychoeducation. This was the first study to evaluate CBM-I in naturalistic treatment for adults seeking IRT for OCRDs. Findings support the feasibility and acceptability of CBM-I in this novel sample and setting. A larger scale RCT is needed to determine whether CBM-I can enhance OCRD treatment response. 相似文献

Clinical perfectionism contributes to the onset and maintenance of multiple psychological concerns. We conducted a randomized, longitudinal test of the efficacy of a web-based intervention for perfectionism (specifically, cognitive bias modification, interpretation retraining; CBM-I), compared to an active treatment comparison condition (specifically, guided visualization relaxation training) for reducing perfectionism and related psychopathology. College students (N = 167) with elevated perfectionism were randomized to one of the two study conditions and were asked to complete their assigned intervention twice weekly for 4 weeks. Participants completed measures of perfectionism and psychological symptoms at baseline, 2 weeks (midway through the intervention period), 4 weeks (at the conclusion of the intervention period), and 8 weeks (1 month follow-up). CBM-I was rated as acceptable overall, though relaxation training was rated slightly more favorably. CBM-I outperformed relaxation training on improving perfectionism-relevant interpretation biases (i.e., increasing nonperfectionistic interpretations and decreasing perfectionistic interpretations), though with small effect sizes and inconsistency across study timepoints. Self-reported perfectionism showed small decreases across time in both intervention conditions. Support was found for a key hypothesized mechanism of CBM-I, such that randomization to CBM-I had a longitudinal, indirect effect on decreasing psychopathology symptom scores through improving perfectionism-relevant interpretation biases. However, in light of small effect sizes, the present study failed to provide compelling evidence that CBM-I for perfectionism contributes meaningfully to the treatment of perfectionism. 相似文献

This study examines the association between Sense of Coherence and anxiety and depression amongst patients at risk of hereditary
cancer receiving genetic counseling. When writing this article, 144 patients referred for genetic counseling due to a suspicion
of hereditary cancer in the family were recruited for this multicentered longitudinal study on the psychosocial aspects of
genetic counseling in Norway. A total of 96 (66%) patients responded to the follow-up survey distributed 6 months after genetic
counseling. This survey included the Sense of Coherence-29 Scale, Impact of Event Scale, and Hospital Anxiety and Depression
Scale. Multiple regression analyses were applied. Our results show association between cancer-related distress and symptoms
of anxiety and depression. Sense of Coherence is significantly associated with both anxiety and depression. The hypothesis
of Sense of Coherence buffering cancer-related distress and the possible impact of these findings for genetic counseling are
discussed. 相似文献

Fundamental differences between current and past knowledge in the field of biotechnology mean that we now have at our disposal the means to irreversibly change what is meant by ‘human nature’. This paper explores some of the ethical issues that accompany the (as yet tentative) attempt to increase scientific control over the human genetic code in what amounts to a diminishing of difference and the reduction of human life to scientific explanations at the expense of spiritual, cultural and communal considerations. Within such a limited view, the critical role of education is reduced in favour of promoting psychological efficiency, with the possibility of accelerating learning and increasing intellectual capacity through genetic manipulation. A major concern expressed in the paper is the fine line between corrective therapy and psychological enhancement: Who should be defining the normal range of human difference? And what degree of caution should be required in redesigning future generations? The unknown dangers inherent in the (perhaps irreversible) application of genetic technology to human life suggests that current precautions may not go far enough in recognising that education is a contestable field. 相似文献

Neuropsychological investigation of the development of the mnesic function in mental retardation has primarily focused on evaluating short-term memory (STM). Studies have often documented a reduced verbal short-term memory span in individuals with mental retardation and with Down syndrome in particular, compared to groups of mental age-matched controls. However, recent evidence suggests that verbal short-term memory is not equally impaired in all individuals with mental retardation. Findings in children with Williams syndrome are particularly relevant in this regard. Also, data concerning STM for visual information suggest that visual-object and visual-spatial working memory may be differently compromised in people with mental retardation. In particular, individuals with Williams syndrome exhibit specific difficulties in visual-spatial but not in visual-object working memory tasks compared to typically-developing children matched for mental age. Instead, people with Down syndrome show reduced performance in both visual-spatial and visual-object tests. Taken together, these results reinforce the view that intellectual disability is not a unitary condition characterized by homogeneous slowness of cognitive development but a variety of conditions in which some cognitive functions may be more disrupted than others. The finding that the working memory deficit in individuals with Williams and Down syndrome may be qualitatively differentiated also supports the hypothesis that it is not simply a manifestation of general cognitive impairment but, rather, the expression of a specific deficit of a discrete cognitive ability. 相似文献

Foraging- and feeding-related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area-restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor behavior and cognition and reveal an evolutionary progression toward increasing internal connections between prefrontal cortex and striatum in moving from amphibian to primate. The basal ganglia in higher vertebrates show the ability to transfer dopaminergic activity from unconditioned stimuli to conditioned stimuli. The evolutionary role of dopamine in the modulation of goal-directed behavior and cognition is further supported by pathologies of human goal-directed cognition, which have motor and cognitive dysfunction and organize themselves, with respect to dopaminergic activity, along the gradient described by ARS, from perseverative to unfocused. The evidence strongly supports the evolution of goal-directed cognition out of mechanisms initially in control of spatial foraging but, through increasing cortical connections, eventually used to forage for information. 相似文献
