Using a dual-target identification task during rapid serial visual presentation (RSVP), we examined facilitation and interference effects exerted by emotional stimuli. Emotionally arousing first targets (T1s) were encoded with higher accuracy than neutral T1s. At the same time, identification of a second neutral target (T2) was impaired reflecting a failure of disengaging attention from arousing T1s. Similar interference was triggered by arousing filler stimuli that were not voluntarily searched for in the RSVP stream (Experiment 2). In Experiment 3, we showed that interference is reduced (though facilitation for arousing T1s is maintained) when the second task itself involves variations in emotional arousal. Vice versa, when arousal associated with the T2 stimulus was predictable, interference recurred (Experiment 4). Our findings indicate that the perceived emotional intensity of a stimulus is a determinant of successful identification during RSVP: Encoding of arousing stimuli is reliably facilitated. Interference effects with subsequent processing arise independently and are strongly modulated by the overall task context and specific processing strategies. 相似文献

What is it we do when we philosophize about a word? How are we to act as we ask the philosophical question par excellence, “What is … ?” These questions are addressed here with particular focus on Troy Jollimore's Love's Vision and contemporary theories of love. Jollimore's rationalist account of love, based on a specific understanding of “reasons for love,” illustrates a particular philosophical mistake: When we think about a word, we are prone to believe that even though “the sense of the word” that we investigate may be up for grabs, the other words we use when we do these investigations are not. Jollimore's exploration of love is guided by specific conceptions of “reasons” and “rationality” that remain unquestioned. The article argues that we may have to rethink a great number of words as we embark on the task of uncovering the sense of one word. 相似文献

社会学要摆脱目前面临的危机,成为把握全部社会性事物及其复杂性的普遍性理论,也必须将理论自身当作对象,这就是说,具有普遍性要求的社会学理论必须是差别的理论、自我参照的理论.因而,社会学必须与其他的、交叉学科的富有成果的理论相联系,并为此选择出一个自我参照的、"自我塑成的"系统的理论.运用这一理论,不确定的复杂性被转化为能够确定的、在科学意义上有价值的复杂性,从而简化复杂性.《社会诸系统》正是本着这样一种思路做出的在一个被设想为没有中心的世界和一个被设想为没有中心的社会中发展出一个多中心的(因而也是多语境)理论的尝试. 相似文献

In a recent paper, Peter Singer suggests that some interesting new findings in experimental moral psychology support what
he has contended all along—namely that intuitions should play little or no role in adequate justifications of normative ethical
positions. Not only this but, according to Singer, these findings point to a central flaw in the method (or epistemological
theory) of reflective equilibrium used by many contemporary moral philosophers. In this paper, we try to defend reflective equilibrium from Singer’s attack
and, in part, we do this by discussing Singer’s own favoured moral methodology as outlined in his Practical Ethics. Although basing ethics solely on (certain kinds of) intuitions certainly is problematic, we argue, basing it solely on ‘reason’
gives rise to similar problems. The best solution would arguably be one which could strike a balance between the two—but,
we suggest, this is precisely what reflective equilibrium is all about. 相似文献

We examined the role of impulsivity in the development of peptic ulcer disease (PUD). The subjects were initially healthy 4636 hospital employees aged 19–62 who responded to a questionnaire on personality, health habits, mental health, and PUD in 1998 and 2000. We used multivariate logistic analyses to determine the relationship between impulsivity and newly-diagnosed PUD among those employees who did not have PUD at baseline. Impulsivity was assessed with the Karolinska Scale of Personality. High level of impulsivity was associated with increased 2-year incidence of doctor-diagnosed PUD after adjustment of age, gender, education and shift work (odds ratio = 2.42, 95% confidence interval = 1.21–4.82). Additional adjustment for the effects of smoking, alcohol consumption, BMI, physical activity, minor psychiatric morbidity and diagnosed depression and other psychiatric disease had little effect on this relationship. The present study suggests that impulsivity may be a risk factor for the development of PUD. 相似文献

The present study examined the interaction between vital exhaustion and cardiac reactivity and recovery on preclinical atherosclerosis assessed by carotid intima-media thickness (IMT) in young men and women. We measured heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) in response to mental arithmetic and speech tasks. Vital exhaustion and carotid IMT were also measured. Significant associations were observed for men aged 28-37 years, but not for men aged 22-25 years, nor for women in these age groups. It was shown that, among highly exhausted men in the older age group, lower HR reactivity was related to greater IMT. Our results also imply that, among non-exhausted men in this age group, slow HR and RSA recovery after acute stress predicted higher IMT. These results suggest that long-term stress as assessed by vital exhaustion is a risk only if it has resulted in ineffective cardiac stress reactivity. Autonomic imbalance resulting from chronic stress may be the common mechanism linking vital exhaustion and cardiac responsiveness to an increased risk of atherosclerosis. 相似文献

Prior irreversible investments of money, time, or effort referred to as sunk costs frequently lead to decisions to continue a chosen course of action despite that this is irrational. With the aim of demonstrating that such escalation of commitment is a special case of a more general phenomenon, two experiments were carried out employing undergraduates as participants. Experiment 1 showed for fictitious personal and business investment scenarios that both prior losses and gains (sunk outcomes) affected choices to continue or discontinue the investment. In Experiment 2 the effect of sunk outcomes was reduced although not eliminated by a monetary bonus that in one condition depended on the future outcomes of the second gamble in two-stage gambles, in another condition on the future returns in personal investment scenarios. In support of a more inclusive theory subsuming escalation of commitment, the decisions were affected by both past and future outcomes and both gains and losses. 相似文献

The authors examined the effects of suboptimally presented facial expressions on emotional and attentional responses and memory among 39 young adults viewing video (business news) messages from a small screen. Facial electromyography (EMG) and respiratory sinus arrhythmia were used as physiological measures of emotion and attention, respectively. Several congruency priming effects were found. In particular, happy facial primes prompted increased (a) pleasure ratings, (b) orbicularis oculi EMG activity, (c) perceived trustworthiness, and (d) recognition memory for video messages with a positive emotional tone. Emotional and other responses to video messages presented on a small screen can be modified with suboptimal affective primes, but even small differences in the emotional tone of the messages should be allowed for. 相似文献
