We examine semantic illusions from a dual-process perspective according to which the processes that go into failing or succeeding to detect such illusions can be decomposed into controlled processes (checking the facts in the sentence against the information in memory) and automatic processes (the impression of truth that comes from the semantic associations between the elements in the sentence). These processes, we argue, make largely independent contributions to truth judgments about semantic-illusory sentences. The Process Dissociation Procedure was used to obtain estimates of these two kinds of processes. In Study 1, participants judged whether sentences were true or false while under high or low cognitive load. Cognitive load increased the rate of semantic illusions by specifically affecting controlled processing but not automatic processing. In Study 2, a previous paired-associate learning task also increased the rate of semantic illusions, but it did so by specifically affecting automatic processing, not controlled processing. 相似文献

The present research examined the role of working memory in the pursuit of qualitatively different achievement goals. Pursuit of a mastery-approach goal entails a focus on developing self-referential competence while a performance-approach goal entails a focus on demonstrating normative competence. Across two experiments it was found that, when working memory is loaded, individuals pursuing a mastery-approach goal experienced larger performance decrements than individuals pursuing a performance-approach goal or those in a no-goal control. It was also found that reliance upon working memory intensive strategies (explicit strategies) was more evident for those in a mastery-approach condition, whereas reliance upon less working memory intensive strategies (implicit strategies) was more evident for those in the performance-approach condition. Results suggest that a motivated focus on developing self-referential skill relies heavily on working memory, facilitated by the use of deliberative, ‘step-by-step’ strategies during goal pursuit. Conversely, a focus on demonstrating normative skill depends less on working memory, facilitated by the use of more heuristic ‘short-cut’ strategies during goal pursuit. These findings show, for the first time, that working memory plays an important, but selective, role in achievement goal pursuit. 相似文献

When learning items that vary in reward, students improve their scores (i.e., earned reward) with task experience. In four experiments, we examined whether such improvements arise from better selective encoding of items that would earn more (vs. less) reward. Participants studied and recalled words across multiple study-test trials. On each trial, 12 words were slated with different values (typically from 1 to 12), and participants earned the point value assigned to a given word if it was correctly recalled. In all experiments, participants earned more points across the first two trials. In Experiment 1, participants either self-paced their study or had experimenter-paced study and in Experiment 2, some participants were penalised for each second spent during study. Improvements in points earned were related to increases in overall recall but not to selective encoding. In Experiment 3, some participants were given value-emphasised instructions, yet they did not demonstrate selective encoding. In Experiment 4, we used a larger range of point values, but selective encoding still did not account for the improvement in point scores across lists. These results suggest that metacognitively-driven selective encoding is not necessary to observe improvements in value-based learning. 相似文献

Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasises collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task (BT), a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the BT, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterised by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older. 相似文献

Priming effects were tested on the planning of the grasping of common objects under full vision during action performance. Healthy participants took part in four experiments which manipulated the nature of the prime (objects, circular block, rectangular bar) and priming context (blocked vs. mixed). Each experiment relied on four priming conditions: (1) congruent orientation, (2) incongruent orientation, (3) neutral prime, and (4) no prime. Priming was observed to have a facilitating effect on visually guided grasping when the object to be grasped was primed by a congruently oriented identical object. This effect was rather independent of the priming context (experimental set-up). Our data suggest an object's functional identity may contribute to the priming effect, as well as its intrinsic (e.g., shape, size) and extrinsic (orientation) visual characteristics. We showed that the planning of visually guided grasping is influenced by prior visual experience, and thus that grasping is not based exclusively on real-time processing of visual information. 相似文献

Interest in entrepreneurship is intense in many parts of the world and this has arisen because of the association between new venture creation and economic development. Entrepreneurship is a process that often leads to the creation of new enterprises but in this article the concept is broadened to include innovative and enterprising behaviour within existing organizations. While it is recognized that entrepreneurs and entrepreneurship are the products of various societal, organizational, and individual factors, this article focuses on the inherent personal traits of individuals that dispose them to engage in entrepreneurial acts. Some approaches to assessing the entrepreneurial personality are examined, but the principal focus is on pencil and paper measures of entrepreneurial attributes. Various instruments that purport to measure key entrepreneurial characteristics such as need for achievement, locus of control, and creative tendencies are considered and relevant empirical evidence is reported. A consideration of the appropriateness of the Durham University Business School's General Enterprising Tendency test as a composite instrument for assessing enterprising or entrepreneurial tendencies follows along with some statistical norms for this test, which should prove useful for practitioners and academics alike. Finally, some problems with trait theories of entrepreneurship are discussed. 相似文献

ABSTRACT Candidates for cardiac bypass surgery often experience cognitive decline. Such decline is likely to affect their everyday cognitive functioning. The aim of the present study was to compare cardiac patients' ratings of their everyday cognitive functioning against significant others' ratings and selected neuropsychological tests. Sixty-nine patients completed a battery of standardised cognitive tests. Patients and significant others also completed the Everyday Function Questionnaire independently of each other. Patient and significant other ratings of patients' everyday cognitive difficulties were found to be similar. Despite the similarities in ratings of difficulties, some everyday cognitive tasks were attributed to different processes. Patients' and significant others' ratings were most closely associated with the neuropsychological test of visual memory. Tests of the patients' verbal memory and fluency were only related to significant others' ratings. Test scores of attention and planning were largely unrelated to ratings by either patients or their significant others. 相似文献

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge. 相似文献

This study examined how toddlers gain insights from source video displays and use the insights to solve analogous problems. The sample of 2- and 2.5-year-olds viewed a source video illustrating a problem-solving strategy and then attempted to solve analogous problems. Older, but not younger, toddlers extracted the problem-solving strategy depicted in the video and spontaneously transferred the strategy to solve isomorphic problems. Transfer by analogy from the video was evident only when the video illustrated the complete problem goal structure, including the character’s intention and the action needed to achieve a goal. The same action isolated from the problem-solving context did not serve as an effective source analogue. These results illuminate the development of early representation and processes involved in analogical problem solving. Theoretical and educational implications are discussed. 相似文献

Early experience can alter infants’ interest in faces in their environment. This study investigated the relationship between maternal psychological health, mother–infant bonding, and infant face interest in a community sample. A visual habituation paradigm was used to independently assess 3.5-month old infants’ attention to a photograph of their mother's face and a stranger's face. In this sample of 54 healthy mother–infant pairs, 57% of mothers (N = 31) reported symptoms of at least one of stress response to trauma, anxiety, or depression. Interest in the mother-face, but not stranger-face, was positively associated with the mother's psychological health. In regression analyses, anxiety and depression predicted 9% of the variance in looking to the mother-face. Anxiety was the only significant predictor within the model. No direct associations were found between mother–infant bonding and infants’ face interest. Taken together, these findings indicate that infant's visual engagement with their mother's face varies with maternal symptoms of emotional distress, even within a community sample. 相似文献
