Using naturalistic scenes, we recently demonstrated that confidence?Caccuracy relations differ depending on whether recognition responses are based on memory for a specific feature or instead on general familiarity: When confidence is controlled for, accuracy is higher for familiarity-based than for feature-based responses. In the present experiment, we show that these results generalize to face recognition. Subjects studied photographs of scenes and faces presented for varying brief durations and received a recognition test on which they (1) indicated whether each picture was old or new, (2) rated their confidence in their response, and (3) indicated whether their response was based on memory for a feature or on general familiarity. For both stimulus types, subjects were more accurate and more confident for their feature-based than for their familiarity-based responses. However, when confidence was held constant, accuracy was higher for familiarity-based than for feature-based responses. These results demonstrate an important similarity between face and scene recognition and show that for both types of stimuli, confidence and accuracy are based on different information.  相似文献

Westerners' perceptions tend to focus on salient foreground objects, whereas Asians are more inclined to focus on contexts. We hypothesized that such culturally specific patterns of attention may be afforded by the perceptual environment of each culture. In order to test this hypothesis, we randomly sampled pictures of scenes from small, medium, and large cities in Japan and the United States. Using both subjective and objective measures, Study 1 demonstrated that Japanese scenes were more ambiguous and contained more elements than American scenes. Japanese scenes thus may encourage perception of the context more than American scenes. In Study 2, pictures of locations in cities were presented as primes, and participants' subsequent patterns of attention were measured. Both Japanese and American participants primed with Japanese scenes attended more to contextual information than did those primed with American scenes. These results provide evidence that culturally characteristic environments may afford distinctive patterns of perception.  相似文献

There is minimal research on metacognition in alcohol‐intoxicated participants. Study 1 examined metacognition across sober, intoxicated, and placebo groups, with the intoxicated group's breath alcohol concentration reaching 0.074 g/210 L on average immediately prior to the metacognition task. Participants answered cued recall general knowledge questions and provided confidence ratings and feeling‐of‐knowing judgments. They then completed a recognition (i.e., multiple choice) version of the same task, indicating an answer and a confidence rating for each question. Findings suggest that metacognitive accuracy generally did not vary across intoxication levels, although the control group's retrospective confidence judgments better discriminated between accurate and inaccurate responses than the alcohol groups in the recognition task. Study 2 surveyed academic psychologists about their expectations regarding the relation between alcohol and metacognition. Study 1's results were counter to their expectations, as respondents generally predicted a relation would be present. We discuss the implications for alcohol and memory.Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

This study examines how employees’ perceptions of specific features of the organizational context—organizational politics and procedural justice—are related to their evaluations of psychological contract breach and subsequent attitudes and behaviors. Across three studies, we examined the appropriateness of four models for describing relationships among the focal constructs. Results of these studies support (a) an environmental responsiveness model in which psychological contract breach mediates the effects of politics and justice on employee outcomes, and (b) a general fairness evaluation model where politics, justice, and psychological contract breach serve as indicators of a higher order factor that predicts employee attitudes and behavior. Implications and directions for future research are presented.  相似文献

Two longitudinal field experiments in a middle school examined how a brief "values affirmation" affects students' psychological experience and the relationship between psychological experience and environmental threat over 2 years. Together these studies suggest that values affirmations insulate individuals' sense of belonging from environmental threat during a key developmental transition. Study 1 provided an analysis of new data from a previously reported study. African American students in the control condition felt a decreasing sense of belonging during middle school, with low-performing students dropping more in 7th grade and high-performing students dropping more in 8th grade. The affirmation reduced this decline for both groups. Consistent with the notion that affirmation insulates belonging from environmental threat, affirmed African American students' sense of belonging in Study 1 fluctuated less over 2 years and became less contingent on academic performance. Based on the idea that developmentally sensitive interventions can have long-lasting benefits, Study 2 showed that the affirmation intervention was more effective if delivered before any drop in performance and subsequent psychological toll could unfold. The role of identity threat and affirmation in affecting the encoding of social experience, and the corresponding importance of timing treatments to developmentally sensitive periods, are explored.  相似文献

We examined the effects of colour cues on the express categorization of natural scenes. Using a go/no-go paradigm sensitive to fast recognition processes, we measured early event-related potential (ERP) correlates of scene categorization to elucidate the processing stage at which colour contributes to scene recognition. Observers were presented with scenes belonging to four colour-diagnostic categories (desert, forest, canyon and coastline). Scenes were presented in one of three forms: Diagnostically coloured, nondiagnostically coloured, or greyscale images. In a verification task, observers were instructed to respond whenever the presented stimulus matched a previously presented category name. Reaction times and accuracy were optimal when the stimuli were presented as their original diagnostically coloured version, followed by their greyscale version, and lastly by their nondiagostically coloured version. These effects were mirrored in the early (i.e., 150 ms following stimulus onset) ERP frontal correlates. Their onset was delayed for greyscale scenes compared to diagnostically coloured scenes, and for nondiagnostically coloured scenes compared to the other two conditions. Frontal ERP amplitudes also decreased for greyscale and nondiagnostically coloured scenes. Together, the results suggest that diagnostic colours are part of the scene gist responsible for express scene categorization.  相似文献

All languages rely to some extent on word order to signal relational information. Why? We address this question by exploring communicative and cognitive factors that could lead to a reliance on word order. In Study 1, adults were asked to describe scenes to another using their hands and not their mouths. The question was whether this home-made "language" would contain gesture sentences with consistent order. In addition, we asked whether reliance on order would be influenced by three communicative factors (whether the communication partner is permitted to give feedback; whether the information to be communicated is present in the context that recipient and gesturer share; whether the gesturer assumes the role of gesture receiver as well as gesture producer). We found that, not only was consistent ordering of semantic elements robust across the range of communication situations, but the same non-English order appeared in all contexts. Study 2 explored whether this non-English order is found only when a person attempts to share information with another. Adults were asked to reconstruct scenes in a non-communicative context using pictures drawn on transparencies. The adults picked up the pictures for their reconstructions in a consistent order, and that order was the same non-English order found in Study 1. Finding consistent ordering patterns in a non-communicative context suggests that word order is not driven solely by the demands of communicating information to another, but may reflect a more general property of human thought.  相似文献

Civil plaintiffs often seek compensation for their psychological injuries. Yet little is known about jurors' preconceived notions (or schemas) for a prospective plaintiff's pain and suffering. The present studies examined (a) whether jurors have psychological injury schemas (Studies 1 and 2), (b) whether their existence and development vary by the type of civil case (Studies 1 and 2) or its severity (Study 2), and (c) how psychological injury schemas compare with physical injury schemas on a number of theoretically and legally relevant judgments (e.g., injury severity, availability, and plaintiff credibility; Study 2). Study 1 (N = 233) presented undergraduate mock jurors with 2 negligence incidents (car accident and slip and fall) and 2 intentional tort incidents (sexual assault and kidnapping) and asked them to report the typical incident and injuries that would result from the defendant's conduct. Results supported the sparse existence of psychological injury schemas but found that they were more developed in the kidnapping and sexual assault incidents than in the car accident and slip and fall incidents. Study 2 (N = 288) additionally manipulated incident schema severity (mild vs. severe) while having participants separately report and rate their psychological and physical injury schemas on judgments of legal and theoretical interest. Results indicated that although mock jurors' psychological injury schemas contained fewer injuries than their physical injury schemas, the reported psychological injuries were rated as more severe than physical injuries. We discuss how schemas may underlie the disparate treatment of psychological and physical injuries by legal decision‐makers.  相似文献

In 2 experimental studies, we examined a way to overcome nonbeneficiaries' resistance to employment equity (EE) policies-participation in formulating the policy. We operationalized participation in terms of instrumental versus noninstrumental voice and proposed that nonbeneficiaries would be more likely to support an EE policy when allowed instrumental participation in the policy's development. Further, we proposed psychological ownership as the mediating mechanism underlying the effects of instrumental participation. Study 1 examined participation effects for a gender-based EE policy and Study 2 for a race-based EE policy. As predicted, we found that nonbeneficiaries (men in Study 1; Whites in Study 2) in the instrumental participation condition expressed greater behavioral intentions to promote the policy (Studies 1 and 2) and were more likely to engage in a behavior promoting the policy (Study 2). We also found support for psychological ownership as the underlying mediating mechanism in both studies. Contributions to theory and practice are discussed.  相似文献

Lower cognitive ability is a risk factor for some forms of severe psychiatric disorder, but it is unclear whether it influences risk of psychological distress due to anxiety or the milder forms of depression. The participants in the present study were members of two British birth national birth cohorts, the 1958 National Child Development Survey (n = 6369) and the 1970 British Cohort Study (n = 6074). We examined the association between general cognitive ability (intelligence) measured at age 10 (1970 cohort) and 11 years (1958 cohort) and high levels of psychological distress at age 30 (1970 cohort) or 33 years (1958 cohort), defined as a score of 7 or more on the Malaise Inventory. In both cohorts, participants with higher intelligence in childhood had a reduced risk of psychological distress. In sex-adjusted analyses, a standard deviation (15 points) increase in IQ score was associated with a 39% reduction in psychological distress in the 1958 cohort and a 23% reduction in the 1970 cohort [odds ratios (95% confidence intervals) were 0.61 (0.56, 0.68) and 0.77 (0.72, 0.83), respectively]. These associations were only slightly attenuated by further adjustment for potential confounding factors in childhood, including birth weight, parental social class, material circumstances, parental death, separation or divorce, and behaviour problems, and for potential mediating factors in adulthood, educational attainment and current social class. Intelligence in childhood is a risk factor for psychological distress due to anxiety and the milder forms of depression in young adults. Understanding the mechanisms underlying this association may help inform methods of prevention.  相似文献

Four studies investigated individuals' confidence in predicting near future and distant future outcomes. Study 1 found that participants were more confident in theory-based predictions of psychological experiments when these experiments were expected to take place in the more distant future. Studies 2-4 examined participants' confidence in predicting their performance on near and distant future tests. These studies found that in predicting their more distant future performance, participants disregarded the format of the questions (e.g., multiple choice vs. open ended) and relied, instead, on their perceived general knowledge (e.g., history knowledge). Together, the present studies demonstrate that predictions of the more distant future are based on relatively abstract information. Individuals feel more confident in predicting the distant future than the near future when the predictions concern outcomes that are implied by relatively abstract information.  相似文献

Prior research has suggested that configural resemblance between a current scene and a previously experienced but forgotten one may trigger déjà vu experiences. The present study examined whether there is a relationship between the frequency of actual déjé vu experiences, measured by questionnaires, and sensitivity to a configural resemblance between past and present events, measured by questionnaires, and between two scenes presented simultaneously in the laboratory. We measured familiarity ratings and remember–know judgements of several scenes. Some scenes had been previously presented, some were similar to previously presented scenes and the others were dissimilar. Déjà vu tendencies were significantly correlated with sensitivity to similarity in the measured questionnaires and in the laboratory, as well as to a feeling of familiarity for similar scenes. In this study, we found for the first time that people who more frequently experience déjé vu states were also more likely to regard themselves as sensitive to similarity and more likely to notice the similarity between two scenes in the laboratory.  相似文献

According to common wisdom, which is supported by extant psychological theorizing, a core feature of political conservatism (vs. liberalism) is the resistance to (vs. acceptance of) societal change. We propose that an empirical examination of the actual difference in political liberals’ and conservatives’ attitudes toward change across different sociopolitical issues may call into question this assumed association between political orientation and relation to change. We examined this proposition in four studies conducted in Germany. In Study 1, we assessed lay people's intuitions about liberals’ and conservatives’ attitudes toward change. Results of this study concur with theoretical assumptions that liberals accept and conservatives resist change. In Study 2a, Study 2b, and Study 3, self‐identified liberals and conservatives were asked whether they would resist or accept change on various sociopolitical issues. Results of these studies suggest that both conservatives and liberals resist and accept societal changes, depending on the extent to which they approve or disapprove of the status quo on a given sociopolitical issue. Overall, our findings provide no evidence for a one‐directional association between political orientation and the tendency to accept or resist change. These findings therefore challenge theoretical and lay assumptions regarding general, context‐independent psychological differences underlying political ideologies.  相似文献

We examined whether participants would use a negative priming (NP) paradigm to categorize color and grayscale images of natural scenes that were presented peripherally and were ignored. We focused on (1) attentional resources allocated to natural scenes and (2) direct versus indirect processing of them. We set up low and high attention-load conditions, based on the set size of the searched stimuli in the prime display (one and five). Participants were required to detect and categorize the target objects in natural scenes in a central visual search task, ignoring peripheral natural images in both the prime and probe displays. The results showed that, irrespective of attention load, NP was observed for color scenes but not for grayscale scenes. We did not observe any effect of color information in central visual search, where participants responded directly to natural scenes. These results indicate that, in a situation in which participants indirectly process natural scenes, color information is critical to object categorization, but when the scenes are processed directly, color information does not contribute to categorization.  相似文献

In spite of the safety and efficiency of the COVID-19 vaccines and the many promotion efforts of political and expert authorities, a fair portion of the population remained hesitant if not opposed to vaccination. Public debate and the available literature point to the possible role of people's attitudes towards medical institutions as well as their preference for complementary and alternative medicine (CAM) on their motivations and intentions to be vaccinated. Other potential ideological factors are beliefs about environmental laissez-faire and divine providence insofar as they encourage people to let the pandemic unfold without human interference. In three cross-sectional samples (total N = 8214), collected at successive moments during the Belgian vaccination campaign, the present research examines the distal role of these psychological and ideological factors on vaccination intentions via motivational processes. Study 1 gauges the relation between trust in medical institutions and preference for CAM on intentions to get vaccinated via motivations. Study 2 examined the role of beliefs in the desirability of letting nature take its course (‘environmental laissez-faire beliefs’) on vaccination intention via motivations. Study 3 tests whether people's adherence to environmental laissez-faire and beliefs about divine providence are linked to their motivations for vaccination via trust in the medical institutions and CAM. Results show that adherence to CAM has a deleterious effect on vaccination intentions, whereas trust in medical institutions has a positive effect. Both ideological factors pertaining to external control are only moderately related, with environmental laissez-faire beliefs having stronger effects on CAM, medical trust and vaccination motivations. We discuss the importance of this set of results in light of the growing interest in CAM and the increasing presence of messages appealing to the environment.  相似文献

The present study was designed to assess whether certain contexts influenced material reactions to children's compliant and noncompliant behavior. Study 1 examined the following contextual variables: chronic negative conditions of the child (physical illness and psychological disturbance) and recent life events experienced by the child (both positive and negative). Study 2 examined maternal mood states as another contextual variable. Results indicated that these contexts relate to differential choices of discipline techniques, based on maternal self-report. These data are examined in light of the literature on treatment acceptability and are discussed in terms of a signal-detection model. Clinical applications are addressed, and suggestions for future research are offered.Portions of this paper were presented at the meeting of the Association for Advancement of Behavior Therapy, Philadelphia, November 1984.We express gratitude to the Research Council of the University of North Carolina at Greensboro for Research Council Grant 2110 218 00000 7719 and to the following for their assistance: James Herbert, Nancy Quinn, Carol Roberson, Ira Turkat, and Marilyn Williams.  相似文献

Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed.  相似文献

In educational and psychological measurement when short test forms are used, the asymptotic normality of the maximum likelihood estimator of the person parameter of item response models does not hold. As a result, hypothesis tests or confidence intervals of the person parameter based on the normal distribution are likely to be problematic. Inferences based on the exact distribution, on the other hand, do not suffer from this limitation. However, the computation involved for the exact distribution approach is often prohibitively expensive. In this paper, we propose a general framework for constructing hypothesis tests and confidence intervals for IRT models within the exponential family based on exact distribution. In addition, an efficient branch and bound algorithm for calculating the exact p value is introduced. The type-I error rate and statistical power of the proposed exact test as well as the coverage rate and the lengths of the associated confidence interval are examined through a simulation. We also demonstrate its practical use by analyzing three real data sets.  相似文献

Emotional-neutral pairs of visual scenes were presented peripherally (with their inner edges 5.2 degrees away from fixation) as primes for 150 to 900 ms, followed by a centrally presented recognition probe scene, which was either identical in specific content to one of the primes or related in general content and affective valence. Results indicated that (a) if no foveal fixations on the primes were allowed, the false alarm rate for emotional probes was increased; (b) hit rate and sensitivity (A') were higher for emotional than for neutral probes only when a fixation was possible on only one prime; and (c) emotional scenes were more likely to attract the first fixation than neutral scenes. It is concluded that the specific content of emotional or neutral scenes is not processed in peripheral vision. Nevertheless, a coarse impression of emotional scenes may be extracted, which then leads to selective attentional orienting or--in the absence of overt attention--causes false alarms for related probes.  相似文献
