ABSTRACT— Refinements in Darwin's theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic "social instincts," or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision-making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is. 相似文献

A version of the Hebb repetition task was used with faces to explore the generality of the effect in a nonverbal domain. In the baseline condition, a series of upright faces was presented, and participants were asked to reconstruct the original order. Performance in this condition was compared to another in which the same stimuli were accompanied by concurrent verbal rehearsal to examine whether Hebb learning is dependent on verbal processing. Baseline performance was also compared to a condition in which the same faces were presented inverted. This comparison was used to determine the importance in Hebb learning of being able to visually distinguish between the list items. The results produced classic serial position curves that were equivalent over conditions with Hebb repetition effects being in evidence only for upright faces and verbal suppression as having no effect. These findings are interpreted as posing a challenge to current models derived from verbal-domain data. 相似文献

ABSTRACT— The otoacoustic emissions (OAEs) measured in a collection of special populations of humans and certain nonhuman species suggest that OAEs may provide a window into some processes of human prenatal development and sexual differentiation. For reasons that are unclear, OAEs appear to be highly sensitive to events occurring during prenatal development that seem to be related to the degree of exposure to androgens a fetus receives. The (largely circumstantial) evidence for a relationship between androgen exposure and OAE strength comes from a series of studies of twins, children with attention-deficit/hyperactivity disorder, people of differing sexual orientations, and spotted hyenas, among others. Some conclusions are bolstered by parallel studies using auditory evoked potentials (AEPs). OAEs and AEPs are simple, objective, noninvasive measures that appear to have potential as tools of value to researchers working on a wide variety of basic and applied topics beyond audition. 相似文献

Research has demonstrated that risk of violent behavior is high in individuals who display psychopathic traits. However, prediction of general aggression, and in particular unprovoked aggression, in nonforensic men who possess such traits has received little experimental attention to date. This study examined the role of psychopathic traits in the prediction of unprovoked aggression in a nonforensic sample. One hundred and five men completed the Levenson Self-Report Psychopathy Scales and competed in a sham aggression paradigm. These men were identified as unprovoked aggressors, provoked aggressors, and provoked nonaggressors contingent on their responses to the experimental paradigm. Findings indicated that men with high levels of psychopathic traits had a 30% greater probability of becoming aggressive in the absence of provocation relative to those with lower psychopathic traits. Results also indicated that unprovoked aggressors evinced more general aggression when provocation was initiated. Findings are discussed in terms of the importance of trait-based risk factors in the prediction of seemingly random, unprovoked aggression. 相似文献

To investigate the neural basis of age-related source memory (SM) deficits, young and older adults were scanned with fMRI while encoding faces, scenes, and face-scene pairs. Successful encoding activity was identified by comparing encoding activity for subsequently remembered versus forgotten items or pairs. Age deficits in successful encoding activity in hippocampal and prefrontal regions were more pronounced for SM (pairs) as compared with item memory (faces and scenes). Age-related reductions were also found in regions specialized in processing faces (fusiform face area) and scenes (parahippocampal place area), but these reductions were similar for item and SM. Functional connectivity between the hippocampus and the rest of the brain was also affected by aging; whereas connections with posterior cortices were weaker in older adults, connections with anterior cortices, including prefrontal regions, were stronger in older adults. Taken together, the results provide a link between SM deficits in older adults and reduced recruitment of hippocampal and prefrontal regions during encoding. The functional connectivity findings are consistent with a posterior-anterior shift with aging previously reported in several cognitive domains and linked to functional compensation. 相似文献

Knowledge of sequential relationships enables future events to be anticipated and processed efficiently. Research with the serial reaction time task (SRTT) has shown that sequence learning often occurs implicitly without effort or awareness. Here, the authors report 4 experiments that use a triplet-learning task (TLT) to investigate sequence learning in young and older adults. In the TLT, people respond only to the last target event in a series of discrete, 3-event sequences or triplets. Target predictability is manipulated by varying the triplet frequency (joint probability) and/or the statistical relationships (conditional probabilities) among events within the triplets. Results reveal that both groups learned, though older adults showed less learning of both joint and conditional probabilities. Young people used the statistical information in both cues, but older adults relied primarily on information in the 2nd cue alone. The authors conclude that the TLT complements and extends the SRTT and other tasks by offering flexibility in the kinds of sequential statistical regularities that may be studied as well as by controlling event timing and eliminating motor response sequencing. 相似文献

Previous research suggests that stress can influence a broad range of memory functions. In this study we investigated the effect of a naturalistic stressor, examination stress, on working memory in young adults. In order to accomplish this aim, participants were tested on psychological and hormonal measures of stress and on Digit Span, once during a low stress period and once during a high stress period. The high examination stress condition was associated with an increase in cortisol and subjective impressions of stress. Although Digits Forward performance did not vary with examination stress, Digits Backward performance improved. These findings suggest that mild increases in stress are associated with improvement in the manipulation component of working memory. However, no correlations were found between working memory and either cortisol or psychological stress. Thus the mechanism by which mild naturalistic stressors improve the manipulation component of working memory needs further investigation. 相似文献

Attention‐deficit/hyperactivity disorder (ADHD) among adults is characterized by inattentiveness and impulsivity. This article provides counselors with information about the etiology, assessment, and treatment of adult ADHD. The identification of the genetic and neurological features of ADHD has led to improvements in evaluation and treatment. Assessment of ADHD requires knowledge of the defining characteristics, subtypes, comorbid features, and functional aspects of ADHD. Effective treatments include both medical management and counseling to address psychosocial deficits. 相似文献

Environmental medicine focuses on acute and chronic effects of chemical and physical environmental influences on health as measured objectively and perceived subjectively. Since these influences are very complex, continuously changing and only partially accessible in scientific experiments, subjective causal attributions can be difficult to prove or disprove. Patients with symptoms attributed to environmental triggers perceive health threats from commonly used chemical agents or electromagnetic radiation, frequently without objective findings. Typical examples are “multiple chemical sensitivity (MCS)”, a generalized self-reported hypersensitivity towards ubiquitous chemicals, or “amalgam sensitivity”, where symptoms are attributed to amalgam from dental fillings. Here, the reported symptoms are almost invariably unspecific and show a high overlap with other medically unexplained syndromes. Based on modern psychosomatic conceptualizations, many environment associated illnesses can be regarded as somatoform disorders and treated as such. Apart from a high psychiatric comorbidity, special attention should be paid to dysfunctional cognitions, emotions and behaviour, and the patient’s often limited quality of life. 相似文献
