Negative correlations between task performance in dynamic control tasks and verbalizable knowledge, as assessed by a post-task questionnaire, have been interpreted as dissociations that indicate two antagonistic modes of learning, one being “explicit”, the other “implicit”. This paper views the control tasks as finite-state automata and offers an alternative interpretation of these negative correlations. It is argued that “good controllers” observe fewer different state transitions and, consequently, can answer fewer post-task questions about system transitions than can “bad controllers”. Two experiments demonstrate the validity of the argument by showing the predicted negative relationship between control performance and the number of explored state transitions, and the predicted positive relationship between the number of explored state transitions and questionnaire scores. However, the experiments also elucidate important boundary conditions for the critical effects. We discuss the implications of these findings, and of other problems arising from the process control paradigm, for conclusions about implicit versus explicit learning processes.  相似文献

Aimed to investigate whether young male and female dancers have different patterns of association between static and dynamic postural balance (PB), 60 dancers from the Australian Ballet School (14–19 years old) were tested for static and dynamic PB with head and lumbar accelerometers. Monotonic relationships between static and dynamic PB were found in head movements among young female dancers in all three directions, but were found for young male dancers in the mediolateral (ML) and anteroposterior (AP) directions only. In lumbar movements, monotonic relationships were found for young female dancers in the AP direction only. Comparing head with lumbar movements in static PB, young male dancers demonstrated monotonic relationships between head and lumbar movements in all 3 directions; however, young female dancers demonstrated monotonic relationships in the AP direction only. In the dynamic measurements, both male and female dancers demonstrated monotonic relationships between head and lumbar movements for all parameters measured in the ML and vertical directions (p < .05). In conclusions, among female dancers static PB ability is correlated with their dynamic ability, whereas among male dancers, no relationship between the static and dynamic PB in the AP direction exists. Male dancers showed head and lumbar coordination in the static PB movement, but both genders manifested no head and lumbar coordination in the AP direction measured for dynamic PB.  相似文献

Schneider and Logan (2006) recently showed that cue-switch and task-switch costs are sensitive to the relative probability of cue switches versus task switches. From this they concluded that taskswitch costs reflect priming of cue-cue transitions rather than actual task-switching operations. However, because this design confounded probability of specific cue transitions with probability of task switches, the results could also reflect task-switch-level adjustments. The present experiment (N = 80) pits the critical prediction of the cue-priming account, namely that costs for high-probability cue-cue transitions are smaller than for low-probability cue-cue transitions, against the main prediction of the switch-probability account, namely that switch probability, irrespective of specific cue-cue transitions, determines switch costs. Whereas the cue-priming prediction was rejected, a specific version of the probability account—that subjects are sensitive to the probability of a task switch, given a cue switch—was fully confirmed. Thus, tasks are in fact the critical representational units that determine task-switch cost.  相似文献

Comparison is fundamental to the practice and subject-matter of philosophy, but has received scant attention by philosophers. This is even so in “comparative philosophy,” which literally distinguishes itself from other philosophy by being “comparative.” In this article, the need for a philosophy of comparison is suggested. What we compare with what, and in what respect it is done, poses a series of intriguing and intricate questions. In Part One, I offer a problematization of the tertium comparationis (the third of comparison) by examining conceptualizations of similarity, family resemblance, and analogy, which it is sometimes argued can do without a tertium comparationis. In Part Two, I argue that a third of comparison is already required to determine what is to be compared, and insofar as that determination precedes the comparison that tertium may be called “pre-comparative.” This leads me to argue against incomparability and to show how anything can indeed be compared to anything. In Part Three, I relate my arguments to what is today commonly labelled “comparative philosophy.” Finally, I raise some questions of ontology and politics in order to demonstrate the relevance of a philosophy of comparison.  相似文献

Two experiments demonstrate the importance of control groups in social comparison research. When comparing to downward targets leads to more favorable self-evaluations than comparing to upward targets, results are often interpreted as demonstrating bidirectional contrast effects. However, without a no-comparison control group, these claims cannot be supported. The present experiments provided participants with performance feedback; some participants received information about an upward target, a downward target, or a bidirectional target (one upward, one downward). Results suggest that social comparison effects are not always bidirectional: Downward and bidirectional comparisons led to contrast whereas upward comparisons were not different from the control. Experiment 2 assessed the role of lateral targets. Overall, results suggest that existing interpretations of contrast effects should be reexamined.  相似文献

Effortful control (EC), the capacity to deliberately suppress a dominant response and perform a subdominant response, rapidly developing in toddler and preschool age, has been shown to be a robust predictor of children’s adjustment. Not settled, however, is whether a view of EC as a heterogeneous rather than unidimensional construct may offer advantages in the context of predicting diverse developmental outcomes. This study focused on the potential distinction between “hot” EC function (delay-of-gratification tasks that called for suppressing an emotionally charged response) and more abstract “cool” EC functions (motor inhibition tasks, suppressing-initiating response or Go-No Go tasks, and effortful attention or Stroop-like tasks). Children (N?=?100) were observed performing EC tasks at 38 and 52 months. Mothers, fathers, and teachers rated children’s behavior problems and academic performance at 67, 80, and 100 months, and children participated in a clinical interview at 100 months. Structural Equation Modeling (SEM) analyses with latent variables produced consistent findings across all informants: Children’s scores in “hot” EC tasks, presumably engaging emotion regulation skills, predicted behavior problems but not academic performance, whereas their scores in “cool” EC tasks, specifically those engaging effortful attention, predicted academic performance but not behavior problems. The models of EC as a heterogeneous construct offered some advantages over the unidimensional models. Methodological and clinical implications of the findings are discussed.  相似文献

This article is a systematic review of the literature on divided attention assessment inclusive of a cognitive and motor task (balance or gait) for use in concussion management. The systematic review drew from published papers listed in PubMed, MEDLINE, EMBASE and CINAHL databases. The search identified 19 empirical research papers meeting the inclusion criteria. Study results were considered for the psychometric properties of the paradigms, the influence of divided attention on measures of cognition and postural control and the comparison of divided attention task outcomes between individuals with concussion and healthy controls (all samples were age 17 years or older). The review highlights that the reliability of the tasks under a divided attention paradigm presented ranges from low to high (ICC: 0.1–0.9); however, only 3/19 articles included psychometric information. Response times are greater, gait strategies are less efficient, and postural control deficits are greater in concussed participants compared with healthy controls both immediately and for some period following concussive injury, specifically under divided attention conditions. Dual task assessments in some cases were more reliable than single task assessments and may be better able to detect lingering effects following concussion. Few of the studies have been replicated and applied across various age groups. A key limitation of these studies is that many include laboratory and time-intensive measures. Future research is needed to refine a time and cost efficient divided attention assessment paradigm, and more work is needed in younger (pre-teens) populations where the application may be of greatest utility.  相似文献

James Bogen misinterprets what Kierkegaard (or more accurately, Johannes de Silentio) meant by the ethical in Fear and Trembling (see Inquiry, 5 [1962], pp. 305–17). Kierkegaard did not intend to depict morality as a system of duties where moral duties derive from the particular position(s) one holds in society. Kierkegaard thought that moral duties were based on universal principles that were divine commands. Although Kierkegaard thought that it was necessary for an action to be moral that it be done in accord with such universal principles, he did not think that this was sufficient. In order to be a moral action, the action must be done not only in accord with certain universal principles but in a certain way. Kierkegaard notes the appropriate way by saying the agent must reveal himself in his action. Thus revelation by the agent and acting in accordance with certain principles are jointly sufficient and singly necessary conditions for an action to be moral.  相似文献

A substantive body of literature suggests that those involved in bullying as perpetrators but particularly victims are at greater risk for psychological maladjustment. In comparison, relatively little is known about associations between bullying-victimization and perpetration and mastery of early adult tasks in domains including romantic relationships, education, work, financial competence, and conduct. These links were tested using data from two Dutch cohorts (RADAR-young, n = 497, 43% girls; TRAILS, n = 2230, 51% girls) who reported on victimization and perpetration at age 11 (TRAILS) and 13 (RADAR-young) and mastery of developmental tasks in early adulthood. Unadjusted regression analyses suggested for both cohorts that perpetrators were less likely to abide the law and more likely to smoke. Victims in TRAILS were less competent in the domains of education, work, and finances, and more likely to smoke in RADAR-young. Adjusting for childhood demographics and child intelligence and including psychopathology in the prediction models substantially reduced the strength of associations between bullying involvement and later outcomes in both cohorts; although association were retained between victimization and welfare dependence and perpetration and crime involvement in TRAILS. Parental support did not buffer associations in either sample and neither were gender differences detected. Overall, findings underline that negative outcomes of bullying are not only a concern for victims but also for their perpetrators although involvement in bullying is not a stable predictor of mastery of developmental tasks when childhood demographics, child intelligence, and psychopathology are taken into account.  相似文献

Social control refers to any reaction by which a bystander communicates to the “perpetrator” of an uncivil behavior that his or her action is not acceptable. In 3 field studies, we examined the factors that affect people's tendency to exert social control. Passersby in the streets were asked how they would react were they to witness different uncivil behaviors. They also rated their appraisal of the situation and the emotions they would feel. The results suggest that 3 factors are primary determinants of social control: the feeling of responsibility to exert it; the perceived legitimacy of social control in the situation; and the extent to which bystanders felt hostile emotions. These results have implications for how to reduce uncivil behaviors.  相似文献

The article investigates the sociocultural implications of the changing modern workplace and of pharmacological cognitive enhancement (PCE) as a potential adaptive tool from the viewpoint of social niche construction. We will attempt to elucidate some of the sociocultural and technological trends that drive and influence the characteristics of this specific niche, and especially to identify the kind of capabilities and adaptations that are being promoted, and to ascertain the capabilities and potentialities that might become diminished as a result. In this context, we will examine what PCE is, and how and why it might be desirable as a tool for adaptation within the workplace. As human beings are, or at least should be allowed to be, more than merely productive, able-bodied and able-minded workers, we will further examine how adaptation to the workplace niche could result in problems in other domains of modern societal life that require the same or other cognitive capabilities. In this context we will also focus on the concept of responsibility and how it pertains to PCE and the modern workplace niche. This will shed some light on the kind of trends related to workplace niche construction, PCE and capability promotion that we can expect in the future, and on the contexts in which this might be either beneficial or detrimental to the individual as a well-rounded human being, and to other members of society.  相似文献

Summary Isomorphism is not a simple concept. As a rule, the term applies to geometrical sameness. However, mathematicians use the term to denote algebriac linear, invertible relationships. Substantively there is also a problem: isomorphism may refer to the brain-experience relation, to the brain-environment relation, or to a three-way relationship of all of these. This commentary summarizes work done and discussions by the author with Wolfgang Köhler regarding these meanings of isomorphism.  相似文献

Without a contextualized definition of self, a growing body of educational research in Asian countries attempts to measure students’ sense of self, such as self-esteem. The research is usually based on theories and measurements that characterize students as conscious and independent selves in an individualist society. This sharply contrasts with the interdependent and unconscious sense of self in a collectivist society. To avoid a misleading assessment of self, researchers and policy makers need to know how students develop a self-construal in a sociocultural context. Therefore, this review of the cultural differences aims to provide a multifaceted definition of self.  相似文献

Why do people experience anger? Most of our knowledge on anger‐triggering events is based on the study of reactions at a single time point in a person's life. Little research has examined how people experience anger in their daily life over time. In this study, we conducted a comprehensive examination of the situational determinants of anger over the course of 3 weeks. Using daily diary methodology, people (N = 173; 2,342 anger episodes) reported their most intense daily anger and, with an open‐ended format, described the trigger. Participants also answered questions on anger intensity, control, and regulatory strategies, along with baseline personality trait measures. Using an iterative coding system, five anger trigger categories emerged: other people, psychological and physical distress, intrapersonal demands, environment, and diffuse/undifferentiated/unknown. Compared with other triggers, when anger was provoked by other people or when the source was unknown, there was a stronger positive association with anger intensity and lack of control. Personality traits (i.e., anger, mindfulness, psychological need satisfaction, the Big Five) showed few links to the experience and regulation of daily anger. Although aversive events often spur anger, the correlates and consequences of anger differ depending on the source of aversion; personality traits offer minimal value in predicting anger in daily life.  相似文献

The present essay examines the conflicting ontological assumptions that one can find behind the word dao in the texts of the Laozi and Zhuangzi and argues that the relative indifference to these texts toward whether or not dao has an ontic reality should not be considered a flaw of early Daoism. Rather, the historical process by which the term dao collects various possible ontological implications can be thought of as a philosophical stance in its own right. That is, if the terms which one is obliged to use in discussing the immaterial necessarily hide, at least as much as they explain, the nature of Being, then it is a reasonable response to decline to ground one??s ethics in an ontology, and that while the resulting philosophy may not qualify as a fully-adumbrated system, this does not diminish its potential usefulness.  相似文献

Therapeutic communities are a commonly used context for counseling persons with drug problems or emotional problems and for other populations of clients. The group dynamics of therapeutic communities are very complex. When the staff members of a therapeutic community develop communication problems with one another or when these staff members become overly involved with residents, staff problems almost always have a negative impact on the program of the therapeutic community. This article describes how staff problems can negatively affect the program of a therapeutic community and also relates the kinds of problems encountered in a therapeutic community to the problems encountered in rehabilitation programs in other settings.  相似文献

The term covert recognition refers to recognition without awareness. In the context of face recognition, it refers to the fact that some individuals show behavioural, electrophysiological or autonomic indices of recognition in the absence of overt, conscious recognition. Originally described in cases of people that have lost their ability to overtly recognize faces (acquired prosopagnosia, AP), covert face recognition has more recently also been described in cases of congenital prosopagnosia (CP), who never develop typical overt face recognition skills. The presence of covert processing in a developmental disorder such as CP is a particularly intriguing phenomenon, and its investigation is relevant for a variety of reasons. From a theoretical point of view, it is useful to help shed light on the cognitive and neural underpinnings of face recognition deficits. From a clinical point of view, it has the potential to aid the design of rehabilitation protocols aimed at improving face recognition skills in this population. In the current review we selectively summarize the recent literature on covert face recognition in CP, highlight its main findings, and provide a theoretical interpretation for them.  相似文献

This paper is set in a context where increased emphasis is being placed on the “consumer’s” role in research. It discusses the limitations of “knowledge base” approaches, which aim to deliver the findings of educational research to practitioners and policymakers. The tensions between what these consumers expect of research and what it can, in fact, offer are explored, and the conditions under which effective communication can be established are outlined and exemplified. It is argued, however, that the processes of such communication, if they are to establish the necessary engagement of consumers with researchers, will have to take account of the ways in which consumers are motivated and able to acquire new knowledge. In conclusion, it is argued that if the engagement is unsuccessful and the consumers are unconvinced of the value and validity of research findings for policy and practice, then researchers’ ideas will take a back seat in the debate about what is to count as high-quality work that should be funded. The function of research as the critical extension of knowledge may then be replaced by enquiry that comes up with the results the customer wants. Her current research interests are in the relationships among policy, practice and research, teachers’ thinking, provision for children with special educational needs and gender in education. Her best known recent book, with Donald McIntyre, isMaking Sense of Teaching (Open University Press).  相似文献

Two experiments examined stereotype and risk factors in suntanning. In the first, subjects formed more positive impressions of a target described as having a suntan than of a control target. Ratings were not as positive, however, if the tan was portrayed as having been intentionally sought. A negative facet to the tan stereotype, in terms of perceived vanity, was also observed. In the second, subjects observed a videotape documenting the risks associated with sun exposure either before or after responding to a questionnaire dealing with attitudes and beliefs about suntanning. The results were consistent with the interpretation that the tape influenced observers in the direction of perceiving a tan as less attractive and enhancing their concern about the dangers of tanning. Subjects displayed the "optimistic bias" effect (Weinstein, 1980) in their estimated likelihood of getting skin cancer. While those with higher reported tan levels were more likely to endorse the attractiveness stereotype associated with a suntan, there was minimal evidence that these individuals were apprehensive or concerned about the risk factors. Their responses to a number of items suggested a measure of resistance or denial. Women generally indicated greater awareness and concern about risks than did men. The results of both studies suggest the important role played by images perceived to be associated with suntanning. In the context of mounting evidence regarding the carcinogenic properties of sun exposure, implications for changes in tanning behavior were considered.  相似文献
