A pupillary dilation response is known to be evoked by salient deviant or contrast auditory stimuli, but so far a direct link between it and subjective salience has been lacking. In two experiments, participants listened to various environmental sounds while their pupillary responses were recorded. In separate sessions, participants performed subjective pairwise-comparison tasks on the sounds with respect to their salience, loudness, vigorousness, preference, beauty, annoyance, and hardness. The pairwise-comparison data were converted to ratings on the Thurstone scale. The results showed a close link between subjective judgments of salience and loudness. The pupil dilated in response to the sound presentations, regardless of sound type. Most importantly, this pupillary dilation response to an auditory stimulus positively correlated with the subjective salience, as well as the loudness, of the sounds (Exp. 1). When the loudnesses of the sounds were identical, the pupil responses to each sound were similar and were not correlated with the subjective judgments of salience or loudness (Exp. 2). This finding was further confirmed by analyses based on individual stimulus pairs and participants. In Experiment 3, when salience and loudness were manipulated by systematically changing the sound pressure level and acoustic characteristics, the pupillary dilation response reflected the changes in both manipulated factors. A regression analysis showed a nearly perfect linear correlation between the pupillary dilation response and loudness. The overall results suggest that the pupillary dilation response reflects the subjective salience of sounds, which is defined, or is heavily influenced, by loudness.  相似文献

Is it possible to enhance the subjective wellbeing of individuals and societies? If so, what are the mental health interventions and economic mechanisms by which subjective wellbeing could be enhanced? We address these questions in our review of the literature on subjective wellbeing. Research now shows that although subjective wellbeing is heritable and stable, it can change substantially over time. Long‐term changes can be affected by positive or negative life events; subjective wellbeing interventions have also proved to be effective for boosting wellbeing for as long as six months. At the societal level, economic factors matter for the subjective wellbeing of citizens. Economic wealth is shown to be a predictor of societal wellbeing across countries and over time. Also, high unemployment severely lowers the wellbeing of individuals and has spillover effects on other societal members, such as the employed. Given the weight of evidence, we are optimistic that subjective wellbeing can be enhanced. For practitioners, policy makers, and economists interested in the wellbeing of individuals, we propose that these findings have implications for mental health practice and economic policies. Future research and methodological issues are discussed.  相似文献

Subjective career success: A study of managers and support personnel   总被引:1,自引:0,他引:1  
Despite popular belief that managers are successful by virtue of their positions, few studies have examined the position-success relationship. In this research, it was predicted that subjective career success is a multi-dimensional construct whose facets can be measured by several factors. Moreover, the phenomenon of career success was tested to see if it would relate to an employee's perception of occupational self-concept and job features. The notion that these dimensions would predict some aspects of career success more accurately for either managers or support personnel was also investigated. The confirming results obtained in this study and their implications for future research as well as practitioners are discussed.An earlier version of this article was presented at the 93rd Annual Convention of the American Psychological Association, Los Angeles, California, 1985.  相似文献

Despite their intuitive plausibility and prominence in theorizing regarding attitude certainty, past studies have provided equivocal evidence for the role of informational and structural consistency factors in perceptions of attitude certainty. The present research attempted to overcome methodological and conceptual limitations in past research in order to establish that amount, cognitive elaboration, and structural consistency of attitude‐relevant knowledge are in fact determinants of attitude certainty. As predicted, certainty was influenced by experimental manipulations of all three constructs. Mediational analyses suggested that the amount and elaboration of information manipulations were mediated by subjective impressions of knowledge. Subjective impressions of amount of thought partially mediated the effects of manipulated elaboration. Finally, perceived ambivalence mediated the effects of manipulated consistency of knowledge.

Repetitive auditory stimulation (with click trains) and visual velocity signals both have intriguing effects on the subjective passage of time. Previous studies have established that prior presentation of auditory clicks increases the subjective duration of subsequent sensory input, and that faster moving stimuli are also judged to have been presented for longer (the time dilation effect). However, the effect of clicks on velocity estimation is unknown, and the nature of the time dilation effect remains ambiguous. Here were present a series of five experiments to explore these phenomena in more detail. Participants viewed a rightward moving grating which traveled at velocities ranging from 5 to 15°/s and which lasted for durations of 500 to 1500 ms. Gratings were preceded by clicks, silence or white noise. It was found that both clicks and higher velocities increased subjective duration. It was also found that the time dilation effect was a constant proportion of stimulus duration. This implies that faster velocity increases the rate of the pacemaker component of the internal clock. Conversely, clicks increased subjective velocity, but the magnitude of this effect was not proportional to actual velocity. Through considerations of these results, we conclude that clicks independently affect velocity and duration representations.  相似文献

This study evaluated whether monitoring performance against an objective measure eliminated ego-depletion and enhanced the accuracy of one's temporal perception. Two independent variables, depletion level and monitoring status, were manipulated in 83 undergraduates (71% female, median age = 21.2 years), who were then measured for persistence on a series of anagram puzzles (first dependant variable) and subjective time perception estimates (second dependant variable). While depleted participants in the nonmonitoring condition exhibited significantly less persistence than those in the performance-monitoring or low-depleted conditions, no differences in time perception scores were detected among the four groups. It appears monitoring behavior against an objective measure is a robust tool to improve self-control ability in depleted individuals; however, this effect is unrelated to perception of time.  相似文献

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度(时间飞逝和时间缓慢)条件下,被试(时间定价组和非时间定价组)对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。  相似文献

Rumination is commonly considered detrimental to forgiveness. In contrast, we propose that different forms of post-transgression thinking are differentially effective for forgiveness, depending on their timing. Concrete thinking focuses on event details, whereas abstract thinking abstracts from details and views the event in a broader context. Following construal level theory, we propose that concrete thinking is increasingly ill-matched, and abstract thinking better matched, to the construal abilities and motivation afforded by psychological distance. Hence, over time, concrete thinking would be negatively, and abstract thinking positively, associated with forgiveness. Two correlational recall studies, with time since transgression measured (Study 1) or manipulated (Study 2), demonstrated that with greater temporal distance concrete thinking was more negatively, and abstract thinking more positively, related to forgiveness. Study 3 employed a prospective-longitudinal methodology over five time-points; intra-individual decrease in concrete thinking and increase in abstract thinking over time were related to higher levels of forgiveness.  相似文献

An experiment was conducted to investigate the effect of a priori probability of false alarms and time pressure on decision-making behaviour in a dynamic task environment. In order to assess whether strategy selection in a dynamic task environment would be adaptive, we modelled the task mathematically, and compared actual decision strategies to the optimal ones. In addition to the selected strategy, we also studied decision-making behaviour at a lower operational level, reflecting the amount of effort subjects are willing to spend on the decision process. Subjects were required to monitor the fitness level of a simulated athlete, who was running a race, and had to provide treatments whenever the athlete's fitness level suggested a real physiological problem. When a decline of the athlete's fitness was caused by a false alarm, a spontaneous recovery would occur after some time, without any need for intervention. Time pressure was manipulated by the rate at which the athlete's fitness level declined. Overall, subjects did not select the most efficient strategy: they dominantly selected information before applying an action, even though it would have been more profitable, and less effortful, just to apply actions. At the operational level, subjects appeared to invest less effort when the probability of false alarms increased and to invest more effort when time pressure increased. However, in contrast to the outcomes of our mathematical model, subjects adjusted the amount of intervention to the a priori probability of false alarms and not to time pressure. Together, the results indicate that the selection of a decision strategy in a dynamic task is less adaptive then is generally concluded from studies with static tasks.  相似文献

In three studies, we examined the influence of restricted and expansive temporal horizons on the sunk‐cost fallacy. The sunk‐cost fallacy occurs when prior investments instead of future returns influence decisions about future investments. When making decisions about future investments, rational decision makers base decisions on future consequences, not already‐invested costs that are “sunk” and cannot be recovered. In Study 1, we restricted young adult college students' temporal horizons by instructing them to imagine that they did not have much longer to live; this manipulation decreased the sunk‐cost fallacy. In Study 2, we replicated Study 1 and also found that the consequences of manipulating temporal horizons were most pronounced for prior investments of time and that prior investments of time and money had different implications for the sunk‐cost fallacy, depending on the social or nonsocial decision domain. In Study 3, we manipulated temporal horizons by instructing students to imagine their time as a college student was coming to an end. Results were mostly similar to Study 2 but also suggested that focusing on one's mortality may have unique consequences. Implications of the three studies for understanding age differences in sunk‐cost decisions, interventions to improve sunk‐cost decisions, and the situations in which interventions might be most needed are discussed.

Across two experiments involving four conditions, Sklar et al. (2012) found that complex subtraction equations can be solved without awareness of the equations. These findings challenge the current position that consciousness is necessary for performing abstract, rule‐following tasks. Given the important implications of their work, we directly replicate Sklar's findings using a larger sample (n = 94) from a different population. Using Continuous Flash Suppression, we investigated if people were able to solve an equation after subliminal (1300 ms) exposure to it. We found evidence for unconscious addition but not subtraction. The effect of unconscious addition was eliminated when participants reported subjective awareness of the primes. Critical review of our results and implications for further research are discussed.  相似文献

Lay theories about willpower—the belief that willpower is a limited versus nonlimited resource—affect self‐control and goal striving in everyday life (Job, Dweck, & Walton, 2010). Three studies examined whether willpower theories also relate to people's subjective well‐being by shaping the progress they make toward their personal goals. A cross‐sectional (Study 1) and two longitudinal studies (Studies 2 and 3) measured individuals’ willpower theories and different indicators of subjective well‐being. Additionally, Study 3 measured goal striving and personal goal progress. A limited theory about willpower was associated with lower subjective well‐being in a sample of working adults (Study 1, N = 258). Further, a limited theory predicted lower levels of well‐being at a time when students faced high self‐regulatory demands (Study 2, N = 196). Study 3 (N = 157) replicated the finding that students with a limited theory experienced lower well‐being in phases of high self‐regulatory demands and found that personal goal progress mediated this relationship. Results suggest that the belief that willpower is based on a limited resource has negative implications not only for self‐control but also for personal goal striving and subjective well‐being.  相似文献

German Abstract     
The magnitude of the cultivation effect for perceptual estimates of social reality has been shown to be affected by a number of contextual factors such as source priming and motivation to process information during judgment construction, and these contextual factors have been linked to the use of heuristic processing strategies when constructing judgments of frequency and probability ( L. J. Shrum, in press ). An experiment that manipulated data collection method explored the implications of these findings. A random sample of general population respondents were randomly assigned to either telephone or mail survey conditions. Because telephone surveys generally result in greater heuristic processing than mail surveys, telephone surveys were expected to produce larger cultivation effects than mail surveys. Results showed that not only were the magnitude of the estimates of affluence, crime, vice, marital discord, and occupations generally greater in the telephone than in the mail survey but the correlation of the estimates with amount of viewing was also greater in the telephone than in the mail survey. The implications for measuring the cultivation effect are discussed.  相似文献

A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) during encoding on subsequent retrieval. Young (YAs, N?=?23) and older (OAs, N?=?23) adults performed two incidental encoding tasks, deep/semantic and shallow/perceptual. Cognitive effort was manipulated by varying decision-making demands. EM performance, indexed by d-prime, was later tested using a recognition task. Results showed that regardless of LoP, increased cognitive effort caused higher d-primes in both age groups. Compared to YAs, OAs showed a lower d-prime after shallow encoding across all cognitive effort levels, and after deep encoding with low cognitive effort. Deep encoding with higher levels of cognitive effort completely eliminated these age differences. Our findings support an environmental-compensatory account of cognitive ageing and can have important therapeutic implications.  相似文献

The effects of underestimated pain and their relationship to habituation   总被引:2,自引:0,他引:2  
The intensity of a painful stimulus was experimentally manipulated in order to induce underpredictions of pain. The experiment aimed at (1) replicating previous findings on the effects of underpredicted pain and (2) investigating the relationship between underpredicted pain and habituation. Most previous findings were replicated: underpredictions of pain were followed by raised expectations of pain and increased fear of pain. In addition, the underprediction had long-term effects on fear of pain, uncertainty about predictions, and expected aversiveness of the painful stimulus. In contrast to previous findings and to Rachman's match/mismatch model, it was found that underpredicted pain can have dishabituating effects. It is theorized that inaccurately predicted pain can cause dishabituation, depending on the extent of the underprediction and on the subjective certainty of the prediction. Theoretical and clinical implications are discussed.  相似文献

Two studies assessed whether mentally simulating specific future events to occur in familiar (vs. unfamiliar) settings indirectly increases meaning life via the subjective quality of the simulations. Participants in both studies (N = 344) were randomly assigned to visualize themselves doing something in familiar (e.g. home) or unfamiliar (e.g. fantasy world) settings in the future. They then rated the subjective quality of these visualizations and completed a measure of meaning in life. We replicated previous findings by showing that mental simulations involving familiar settings were of greater subjective quality than simulations involving unfamiliar settings. However, we also found that simulating future events in familiar (vs. unfamiliar) settings indirectly increased the perceived meaningfulness of life. These findings integrate research in cognitive psychology with research on the psychology of well-being and reveal how mental time travel contributes to the perception that one’s life has meaning.  相似文献

ABSTRACT

The VIA Inventory of Strengths and the VIA model were originally developed to assess and study 24 character strengths. In this paper, I discuss how the VIA Inventory and its character strength model can be applied to the field of moral education with moral philosophical considerations. First, I review previous factor analysis studies that have consistently reported factors containing candidates for moral virtues, and discuss the systematic structure and organization of VIA character strengths. Second, I discuss several issues related to the VIA model, including a lack of previous studies that directly support the moral justifiability of the model and the presence of a fundamental virtue component required for optimal moral functioning in virtue ethics, phronesis, practical wisdom, in the model. Finally, I propose future directions for research on the VIA model in order to address the aforementioned issues and facilitate the application of the model in moral education.  相似文献

Previous research has found that activating negative stereotypes after completion of a task can lead people to feel more certain that they performed poorly (i.e., stereotype validation). The current research examined the implications that stereotype validation may hold for future performance. In two studies, the accessibility of gender stereotypes was manipulated after participants completed an initial test on a topic. After reporting perceptions of their performance, participants completed a follow-up test on the same subject. Consistent with hypotheses, activating negative stereotypes after the initial test was found to increase certainty in negative performance evaluations among stigmatized participants. Importantly, this higher certainty – triggered by stereotypes – predicted decreased performance on the later, follow-up test.  相似文献
