ABSTRACT

Participants in the Healthy Old People in Edinburgh (HOPE) study (N = 398) were assessed on Raven's Progressive Matrices and Logical Memory on up to three occasions. Covariates included education, social class, disease and medication status, blood pressure and study outcome. Raven's score declined linearly with age, whereas decline in Logical Memory was accelerating. There was significant variation in individuals' rates of decline for Ravens but not Logical Memory. Slope–intercept covariances were not significant. Those who later developed dementia already exhibited lower scores, more so for Logical Memory than Raven's. Death and study attrition were related to performance, again greater for Logical Memory. Conclusions: The HOPE approach of progressive screening is a feasible and practical method for studying healthy cognitive ageing. As predicted for an initially healthy sample, rates of decline were relatively homogeneous. The hypothesis of differential decline was not supported, nor was a strict interpretation of the hypothesis that cognitive ageing is entirely pathology driven.  相似文献

People can acquire both true and false knowledge about the world from fictional stories. The present study explored whether the benefits and costs of learning about the world from fictional stories extend beyond memory for directly stated pieces of information. Of interest was whether readers would use correct and incorrect story references to make deductive inferences about related information in the story, and then integrate those inferences into their knowledge bases. Participants read stories containing correct, neutral, and misleading references to facts about the world; each reference could be combined with another reference that occurred in a later sentence to make a deductive inference. Later they answered general knowledge questions that tested for these deductive inferences. The results showed that participants generated and retained the deductive inferences regardless of whether the inferences were consistent or inconsistent with world knowledge, and irrespective of whether the references were placed consecutively in the text or separated by many sentences. Readers learn more than what is directly stated in stories; they use references to the real world to make both correct and incorrect inferences that are integrated into their knowledge bases.  相似文献

ABSTRACT

Engaging publics in participatory events has become a central means to introducing lay people's voices into processes of technoscientific innovation and governance. However, little attention has been paid to the role of aesthetics, especially in terms of opening up potential ways of critically and creatively engaging with technoscientific matters of concern. The terms semblamatic and matters of potentially are proposed as addressing this dimension of aesthetics. Drawing on practice-based design research, a probe workshop with members of energy communities was implemented. Three probe exercises served to open up potential re-articulations of such core themes as energy, communities and futures. Our goals were to examine the whether such probes enabled semblamatic responses and the emergence of matters of potentiality. Findings were mixed. The continued retention of standard meanings of these core themes suggested that such events can be anaesthetic, blunting access to the semblamatic aspects of engagement. Conversely, there was some opening up in which the core themes were creatively re-articulated. The present perspective, with its three novel terms - semblamatic, matters of potentiality, and anaesthetic - might prove useful in alerting scholars to the complex role of aesthetics in the methodological and analytic practices entailed in engagement with publics.  相似文献

The present article describes two studies that examine the impact of teaching students to use gesture to support spatial thinking in the Science, Technology, Engineering, and Mathematics (STEM) discipline of chemistry. In Study 1 we compared the effectiveness of instruction that involved either watching gesture, reproducing gesture, or reading text. The results indicate that students in the reproducing gesture condition produced significantly more gestures while problem solving than students in the other two groups and significantly outperformed the other groups on study measures. In Study 2 we compared the effectiveness of gesture to an instructional approach that involved manually handling concrete models without gesture. Students performed equally well in both conditions; however, students taught with concrete models performed significantly worse if concrete models were not available during assessment. These studies show that gesture is an effective strategy for supporting spatial thinking in STEM disciplines and that this benefit may result from physically simulating spatial transformations.  相似文献

Matching unfamiliar faces is known to be a difficult task. However, most research has tested viewers' ability to match pairs of faces presented in isolation. In real settings, professionals are commonly required to examine photo ID that contains other biographical information too. In three experiments, we present faces embedded in passport frames and ask viewers to make face matching decisions and to check biographical information. We find that the inclusion of a passport frame reduces viewers' ability to detect a face mismatch. Furthermore, the nature of the face match influences biographical data checking—true matches lead to fewer detections of invalid data. In general, viewers were poor at spotting errors in biographical information. This pattern suggests that detection of fraudulent photo ID is even harder than current experimental studies suggest. Possible mechanisms for these effects are discussed. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

The present research examined whether people imitate the language style of others (i.e., the use of function words) as a form of liking when mortality concerns are salient. In Study 1, participants answered questions about death or public speaking and then engaged in an instant messaging conversation with a confederate. In Study 2, participant pairs verbally discussed a news article about increasing homicide rates or the rise in academic pressure. Next, everyone completed measures of self-esteem, life satisfaction, and relationship need satisfaction. The results revealed that, in comparison to the control conditions, participants exhibited greater language style matching (LSM) following reminders of death (Studies 1 & 2). Further, mediational analyses showed that higher LSM after mortality salience was associated with better psychological and social well-being (Study 2). Although the threat of death has been shown to make people more hostile and disparaging toward dissimilar others, the present work suggests that individuals, even strangers, may feel closer through language coordination following thoughts of mortality.  相似文献

We report a study in which faces with a neutral emotional expression were shown on a computer screen. By means of a joystick, participants pulled half of the faces closer (positive approach movement), and pushed the half away (negative avoidance movement). As a result, an operant evaluative conditioning effect occurred in a subsequent affective priming task: Participants responded more quickly to positive target words if they were preceded by a previously pulled face than a pushed face, and vice versa for negative target words. The effect became stronger the more often the faces had been trained to approach or to avoid. No effect was observed on explicit evaluations of the faces: Pushed faces were rated as sympathetic as pulled ones.  相似文献

This study employed an immersed virtual environment (IVE) in the Nijmegen RIVERlab to study spider fearfuls’ attentional and motor reactions to virtual spiders. The participants were exposed to virtual spiders while completing an unrelated task, walking freely through a virtual museum. Compared to non-fearful controls, spider fearfuls showed an increase in state anxiety, they spent more time looking at spiders, and they exhibited spontaneous behavioural avoidance of spiders and visually similar objects. The results extend, and to some degree contradict, those of earlier studies with static pictures, and they speak to the usefulness of state-of-the-art IVEs in fundamental anxiety research.  相似文献

Cochlear implant (CI) devices provide the opportunity for children who are deaf to perceive sound by electrical stimulation of the auditory nerve, with the goal of optimizing oral communication. One part of oral communication concerns meaning, while another part concerns emotion: affective speech prosody, in the auditory domain, and facial affect, in the visual domain. It is not known whether childhood CI users can identify emotion in speech and faces, so we investigated speech prosody and facial affect in children who had been deaf from infancy and experienced CI users. METHOD: Study participants were 18 CI users (ages 7–13 years) who received right unilateral CIs and 18 age- and gender-matched controls. Emotion recognition in speech prosody and faces was measured by the Diagnostic Analysis of Nonverbal Accuracy. RESULTS: Compared to controls, children with right CIs could identify facial affect but not affective speech prosody. Age at test and time since CI activation were uncorrelated with overall outcome measures. CONCLUSION: Children with right CIs recognize emotion in faces but have limited perception of affective speech prosody.  相似文献
