Human control of action in routine situations involves a flexible interplay between (a) task‐dependent serial ordering constraints; (b) top‐down, or intentional, control processes; and (c) bottom‐up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top‐down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and control of goal‐directed action that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non‐routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non‐routine goal‐based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system.  相似文献

Two different types of ruminative coping, depressive rumination and grief rumination, negatively influence bereavement outcome. Although grief-specific rumination is likely to be relevant in the bereavement context no internationally validated scale to measure grief rumination exists. Therefore, the current contribution aims to validate the Utrecht Grief Rumination Scale (UGRS), a scale developed to measure grief-specific rumination, in an English sample. Psychometric properties of the English UGRS were compared with those in a Dutch sample. 204 British adults (89 % women, 11 % men), bereaved on average 16 months ago, and 316 Dutch adults (88 % women, 12 % men), bereaved on average 12 months ago, filled out online questionnaires. Different types of rumination (grief rumination, brooding, reflection, trait rumination) and symptoms of psychopathology (anxiety, depression, complicated grief) were measured. A correlated five factor model provided the best fit for the UGRS. Multi-group comparisons showed that the factor structures of the English and Dutch version of the UGRS were highly similar across language groups. The UGRS showed excellent reliability. Results further supported the construct, convergent, divergent and concurrent validity of the English UGRS. The psychometric properties of the Dutch UGRS corroborated these findings. The UGRS appears a valid instrument to assess grief-specific rumination in international research and may have potential applicability as a clinical instrument to assess rumination in individuals with problematic grief.  相似文献

From the ‘DuPont factory’ case in China, one can see that contemporary ecology is faced with two underlying problems: A lack of responsibility toward the environment beyond being economically profitable, and a lack of care for what is outside of one’s immediate environment. For the purpose of confronting these two problems, I suggest two Confucian concepts: 1. zhengming 正名 (Rectification of names) and 2. datong 大同 (Great Harmony). These two concepts can be used to develop an environmental ethics and thus play a crucial role in solving the two above-mentioned problems. Zhengming is originally a political concept that was put forward by Confucius. According to this concept, everyone should fulfill their duty to the utmost in accordance with their individual roles. Datong is Confucius’ political ideal and emphasizes gong 公 (public) as a spirit for caring for tian xia 天下 (all under Heaven). A Confucian-style harmonious society is achieved by ‘letting every being manifest its mandate to the full’ (ge jin xing fen 各盡性分). When we turn toward the natural environment instead of political affairs, these concepts of zhengming and datong can become a proactive view of environmental ethics. From this view, zhengming emphasizes that ‘humans fulfill their responsibility of being humans’ (ren ren 人人). This means that humans should take responsibility toward the natural world, and one might say that ren ren implies an impetus for protecting the environment. Similarly, datong emphasizes caring for tian xia, by not limiting oneself to certain races, species, national boundaries, or geographical regions. Because of this, I believe that zhengming and datong can certainly resolve the above-mentioned problems: A lack of a sense of responsibility toward the environment, and a lack of a sense of care for what is outside of the confines of one’s immediate environment.  相似文献

Immigrant job applicants are often not fluent in the majority language. This raises the question whether selectors adjust their decision strategy when selecting immigrants. In two field studies (N = 1,949 and N = 156), we examined the decision strategies of professional selectors. Selectors used differential strategies, giving less weight to the test scores and impression scores of immigrants. Dutch language proficiency served as a moderator variable; test scores were considered less important in the employment recommendation especially for immigrants with low language skills. Yet professional selectors also used similar strategies for different groups; the same test scores led to the same recommendations, regardless of ethnicity. In sum, personnel selectors adjusted their decision strategy for immigrants, but this did not lead to immigrants receiving higher recommendations than majority applicants with similar test scores.  相似文献

It is thought that reward-induced motivation influences perceptual, attentional, and cognitive control processes to facilitate behavioral performance. In this study, we investigated the effect of reward-induced motivation on exogenous attention orienting and inhibition of return (IOR). Attention was captured by peripheral onset cues that were nonpredictive for the target location. Participants performed a target discrimination task at short (170 ms) and long (960 ms) cue–target stimulus onset asynchronies. Reward-induced motivation was manipulated by exposing participants to low- and high-reward blocks. Typical cue facilitation effects on initial orienting were observed for both the low- and high-reward conditions. However, IOR was found only for the high-reward condition. This indicates that reward-induced motivation has a clear effect on reorienting and inhibitory processes following the initial capture of attention, but not on initial exogenous orienting that is considered to be exclusively automatic and stimulus-driven. We suggest that initial orienting is completely data-driven, not affected by top-down motivational processes, while reorienting and the accompanying IOR effect involve motivational top-down processes. To support this, we showed that reward-induced motivational processes and top-down control processes co-act in order to improve behavioral performance: High-reward-induced motivation caused an increase in top-down cognitive control, as signified by posterror slowing. Moreover, we show that personality trait propensity to reward-driven behavior (BAS-Drive scale) was related to reward-triggered behavioral changes in top-down reorienting, but not to changes in automatic orienting.  相似文献

Recent decision-making work has focused on a distinction between a habitual, model-free neural system that is motivated toward actions that lead directly to reward and a more computationally demanding goal-directed, model-based system that is motivated toward actions that improve one’s future state. In this article, we examine how aging affects motivation toward reward-based versus state-based decision making. Participants performed tasks in which one type of option provided larger immediate rewards but the alternative type of option led to larger rewards on future trials, or improvements in state. We predicted that older adults would show a reduced preference for choices that led to improvements in state and a greater preference for choices that maximized immediate reward. We also predicted that fits from a hybrid reinforcement-learning model would indicate greater model-based strategy use in younger than in older adults. In line with these predictions, older adults selected the options that maximized reward more often than did younger adults in three of the four tasks, and modeling results suggested reduced model-based strategy use. In the task where older adults showed similar behavior to younger adults, our model-fitting results suggested that this was due to the utilization of a win-stay–lose-shift heuristic rather than a more complex model-based strategy. Additionally, within older adults, we found that model-based strategy use was positively correlated with memory measures from our neuropsychological test battery. We suggest that this shift from state-based to reward-based motivation may be due to age related declines in the neural structures needed for more computationally demanding model-based decision making.  相似文献

The journeyman carpenter Ludwig Tessnow was sentenced to death for four murders by the Greifswald jury court in 1902. The death sentence was upheld during the retrial in 1906 but was later commuted to life imprisonment. According to the unanimous opinion of psychiatric experts Tessnow committed the crimes while in a state of mental incompetence caused by epileptic twilight states. The court, however, ignored this mitigating circumstance in its decision-making process. Seen from a historical perspective, the case is of forensic psychiatric interest because this criminal trial clearly shows the conflicts in competence which arose in the nineteenth century between judges and medical experts when mental competence had to be assessed. It also allows some insight into how mentally ill offenders were dealt with at the beginning of the twentieth century when the influence of public opinion was (and still is) a noteworthy element of prejudgement which was additionally consolidated by the established system of jury courts. The Tessnow case reveals by way of example the usual practice of official consignment of mentally disordered offenders to hospitals at the end of the nineteenth century until the Nazi era. New particulars of the Tessnow findings adequately verified that Tessnow had not been executed in the Greifswald prison as mistakenly believed. It could be proved that Ludwig Tessnow was admitted to the LandesheilanstaltStralsund (state mental hospital in Stralsund) where he became a victim of the Nazi euthanasia program.  相似文献

This essay reflects an ongoing dialogue between a clinician versed in mainstream psychological research and theory, and a social psychologist with experience both as a researcher and contributor to applied undertakings in various domains about the “incremental value” of research-based knowledge—that is, its value beyond that provided by the other sources of knowledge available to the practitioner. These sources include knowledge about the needs and coping strategies of all human beings, as well as knowledge both about the specific life circumstances of those one is seeking to help, and knowledge about language and culture. Examples from the clinical practice of the first author are offered, coupled with in-principle arguments about the underspecified and contingent nature of research-based generalizations. By way of rebuttal, examples of arguably useful findings are provided by the second author—especially findings that serve as correctives to biases in lay psychology (notably unwarranted “dispositionism”) and to widespread shortcomings in judgment and decision-making (particularly, Kahneman and Tversky’s work on “prospect theory” ). Both authors agree on the value of a “bricoleur” treatment strategy that relies on careful attention to the specifics of the case at hand and avoids one-size-fits-all applications of theory and prior research, and both agree that research-based findings are more useful in predicting behavior and designing intervention strategies that apply to groups and large samples of individuals rather than single actors. A concluding discussion focuses on necessary criteria and strategies for increasing the usefulness of laboratory and field research for the practitioner.  相似文献

This essay attempts to examine the difficult question of sex scandals both in public school settings and in the academy. It raises issues over the way authority in the classroom is unequally exercised by both male and female teachers in terms of power and seduction. However, the Law remains explicit when it comes to judging who is at fault within a-student relationship that collapses into the bedroom. The ethics that surround such sexual affairs is raised through the psychoanalytic and philosophical writings of Jacques Lacan. The essay ends by offering a surprised perspective over the question whether an ethics of diabolical evil is possible, given that such affairs are differentiated as post-Oedipal relationships where age differentiations have become blurred.  相似文献

From a proactive agentic perspective, social support is not just seen as a protective cushion against environmental demands. Rather, support may facilitate an individual's self-regulation by enhancing perceived self-efficacy (i.e., enabling hypothesis). In the present study, patient-reported indicators of mobilized and received spousal support as predictors of their own and their spouses' self-efficacy beliefs were investigated within 1 year following radical prostatectomy. During this time frame, postoperative sequelae such as urinary incontinence and erectile dysfunctions are still likely to interfere with couples' everyday activities. Seventy-two patients receiving radical prostatectomy and their spouses participated. Patients' and spouses' self-efficacy beliefs and patients' received and mobilized spousal support were assessed prior to and 12 months following surgery. Additional patient-reported covariates at 1 year post-surgery were degree of bother by urinary incontinence, overall sexual satisfaction, and relationship satisfaction. Results indicated that patients' received spousal support was associated with higher levels of patients' self-efficacy only cross-sectionally, but not longitudinally. Support mobilized by the patient prior to and 1 year after surgery, however, positively predicted spouses' levels and changes in self-efficacy. Results, thus, did not fully confirm predictions by the enabling hypothesis of social support; rather, associated aspects, such as the degree of being mobilized as a provider of support or being needed, seem to enhance agency beliefs in spouses.  相似文献
