On the adolescent neurosis 总被引:1,自引:0,他引:1
Jacobs TJ 《The Psychoanalytic quarterly》2007,76(2):487-513
The author discusses the lifelong impact of adolescence in shaping the adult psyche. Some patients may appear to be as influenced by conflicts of adolescence and the individual solutions arrived at during this period as they are by conflicts and solutions of the oedipal phase, the author maintains. The subphases of early, middle, and late adolescence are discussed both in terms of a review of the psychoanalytic literature and of representative works of literary fiction. Illustrative clinical vignettes are presented as well. 相似文献

The visual environment is highly regular, with particular objects frequently appearing in specific locations. Previous studies
of visual search have shown that people take advantage of such regularities, detecting targets more quickly when they appear
at a predictable location within a given spatial configuration. Moreover, this effect depends on implicit rather than explicit
memory for the configurations. These studies have suggested that implicit long-term memory for contextual information influences
the allocation of attention, modulating the flow of information through visual cortex. The present study used event-related
potentials to provide the first direct support for this proposal. We suggest that this guidance of attention by implicit memory
is important in the natural environment because it allows environmental regularities to influence perception without the intervention
of limited-capacity conscious processes. 相似文献

Following our hypothesis that juvenile emotional and/or cognitive experience should affect learning performance at preweaning age as well as adulthood, the present study in female Wistar rats aimed to examine the impact of (i) avoidance training at preweaning age, (ii) exposure to repeated maternal separation, (iii) the combination of both, and (iv) the blockade of dopaminergic neurotransmission on adult two-way active avoidance learning in rats. We found that preweaning, i.e. three week old, rats were less capable of avoidance learning compared to adults. Our main findings revealed that preweaning avoidance training alone improved avoidance learning in adulthood. Furthermore, maternal separation alone also improved avoidance learning in preweaning and in adult rats, but this effect of maternal separation did not add up to the beneficial effect of preweaning avoidance training on adult learning. In addition, the pharmacological blockade of dopamine receptors during preweaning avoidance training via systemic application of haloperidol impaired preweaning avoidance performance in a dose-dependent manner. Testing the haloperidol-treated preweaning presumed "non-learners" as adults revealed that they still showed improved learning as adults. Taken together, our results strongly support the hypothesis that emotional as well as cognitive experience at preweaning age leaves an enduring "memory trace," which can facilitate learning in adulthood. Our pharmaco-behavioral studies suggest that unlike the adult brain, preweaning learning and memory formation is less dependent on dopaminergic mechanisms, which raises the intriguing question of possible alternative pathways. 相似文献

Mechanisms that lead depressive symptoms to undermine parenting are poorly understood. This review examines cognitive, affective, and motivational processes thought to be responsible for the impact of depressive symptoms on parenting. We present a five-step, action-control model and review 152 studies relevant to 13 regulatory processes. Evidence suggests that depressive symptoms undermine parenting because they reduce child-oriented goals, undermine attention to child input, increase negative appraisals of children and parenting competence, activate low-positive and high-negative emotion, and increase positive evaluations of coercive parenting. Yet, this review reveals significant limitations in knowledge of these processes. Evidence that they mediate depression-parenting relations is scare; important processes remain unstudied; conceptions of regulation are undifferentiated; children’s contributions are largely unexamined; moderating variables are largely unexplored; and methods fail to capture the dynamics of processing input from children. Rigorous testing of such process models holds promise for clarifying the basis of depression-related parenting problems. 相似文献

Recent assessments have shown that capuchin monkeys, like chimpanzees and other Old World primate species, are sensitive to
quantitative differences between sets of visible stimuli. In the present study, we examined capuchins’ performance in a more
sophisticated quantity judgment task that required the ability to form representations of food quantities while viewing the
quantities only one piece at a time. In three experiments, we presented monkeys with the choice between two sets of discrete
homogeneous food items and allowed the monkeys to consume the set of their choice. In Experiments 1 and 2, monkeys compared
an entirely visible food set to a second set, presented item-by-item into an opaque container. All monkeys exhibited high
accuracy in choosing the larger set, even when the entirely visible set was presented last, preventing the use of one-to-one
item correspondence to compare quantities. In Experiment 3, monkeys compared two sets that were each presented item-by-item
into opaque containers, but at different rates to control for temporal cues. Some monkeys performed well in this experiment,
though others exhibited near-chance performance, suggesting that this species’ ability to form representations of food quantities
may be limited compared to previously tested species such as chimpanzees. Overall, these findings support the analog magnitude
model of quantity representation as an explanation for capuchin monkeys’ quantification of sequentially presented food items.

We hypothesized that, in a masculine task, only token women leaders who were empowered through position (by being appointed leader) and expertise (trained with task-relevant information) and legitimated by a male experimenter as credible would be more effective in influencing the performance of their all-male groups than appointed-only and appointed-trained leaders. Thirty women undergraduates each led a small group of male students on a moon survival task. The hypothesis was supported. Videotapes of group interactions revealed that appointed-trained leaders interrupted group members and used tentative tag questions in failed attempts to share their task-relevant knowledge. In addition, group members reported the most dissatisfaction with appointed-trained leaders who, without legitimacy, violated diffused gender roles by presuming to be expert on a masculine task. The importance of the organizational empowerment of token women is underscored. 相似文献

This paper describes a physical model and the mathematical equations specifying the dynamics of a bending line. A computer program is also described that will control real-time displays of a line of points in three-dimensional space and collect psychophysical data from human observers discriminating between different bending motions. 相似文献

Conclusion Tooley's speculative theory, I have tried to show, is beset with difficulties. I warned that this theory threatens to fail in its goal of illuminating the possible nature of a necessitation relation if it employs radical principles about parts and wholes and universals. Secondly, I argued that regardless of how we interpret the crucial phrase existing only as a part of, the speculative theory cannot solve the inference problem without appealing to such radical principles. Finally, I considered and rejected a version of Tooley's speculative theory that attempts to solve the inference problem using the Indiscernibility of Identicals.I conclude that the speculative theory fails. Tooley must fall back to the stipulative theory and live with the lack of an illuminating solution to the inference problem. But this is not to admit defeat. While it would be nice to have a more complete account of its workings, we may view the introduction of the necessitation relation as a theoretical posit, analogous to the positing of subatomic particles in physics to account for various data.I would like to thank Phillip Bricker for his persistent help with this paper. I would also like to thank David Lewis and an anonymous referee for Philosophical Studies for their comments. 相似文献
