Collecting (or “sampling”) information that one expects to be useful is a powerful way to facilitate learning. However, relatively little is known about how people decide which information is worth sampling over the course of learning. We describe several alternative models of how people might decide to collect a piece of information inspired by “active learning” research in machine learning. We additionally provide a theoretical analysis demonstrating the situations under which these models are empirically distinguishable, and we report a novel empirical study that exploits these insights. Our model‐based analysis of participants' information gathering decisions reveals that people prefer to select items which resolve uncertainty between two possibilities at a time rather than items that have high uncertainty across all relevant possibilities simultaneously. Rather than adhering to strictly normative or confirmatory conceptions of information search, people appear to prefer a “local” sampling strategy, which may reflect cognitive constraints on the process of information gathering. 相似文献

In this study, we investigated motor and cognitive procedural learning in typically developing children aged 8–12 years with a serial reaction time (SRT) task and a probabilistic classification learning (PCL) task. The aims were to replicate and extend the results of previous SRT studies, to investigate PCL in school-aged children, to explore the contribution of declarative knowledge to SRT and PCL performance, to explore the strategies used by children in the PCL task via a mathematical model, and to see whether performances obtained in motor and cognitive tasks correlated. The results showed similar learning effects in the three age groups in the SRT and in the first half of the PCL tasks. Participants did not develop explicit knowledge in the SRT task whereas declarative knowledge of the cue–outcome associations correlated with the performances in the second half of the PCL task, suggesting a participation of explicit knowledge after some time of exposure in PCL. An increasing proportion of the optimal strategy use with increasing age was observed in the PCL task. Finally, no correlation appeared between cognitive and motor performance. In conclusion, we extended the hypothesis of age invariance from motor to cognitive procedural learning, which had not been done previously. The ability to adopt more efficient learning strategies with age may rely on the maturation of the fronto-striatal loops. The lack of correlation between performance in the SRT task and the first part of the PCL task suggests dissociable developmental trajectories within the procedural memory system. 相似文献

This study investigated the moderating role of self-esteem on young emerging adults’ in their school-to-work transition phase of graduateness skills and career adaptability. A non-probability convenience sample (n=332) of undergraduate black (98.5%) and female (62%) young emerging adults (18–29 years) at a Further Education and Training (FET) college in South Africa participated in the study. Participants completed the Culture Free Self-esteem Inventory for Adults (CFSEI 2-AD, Battle, 1992), the Graduateness Skills and Attributes Scale (GSAS, Coetzee, 2010) and the Career Adapt-abilities Scale (CAAS, Savickas &; Porfeli, 2012). Hierarchical moderated regression analysis indicated significant interaction effects between self-esteem and overall graduateness, lifelong learning and global/moral citizenship skills and attributes in moderating overall career adaptability. The relationship between the participants’ graduateness skills and attributes (overall graduateness, global/moral citizenship, and lifelong learning) and their career adaptability was significantly stronger when their self-esteem was high than when their self-esteem was low. The finding suggests self-esteem to influence self-perceived graduateness skills and career adaptability in emerging adults. 相似文献

The sibling relationship is complex, unique and important. When one sibling has a developmental disability, siblings can be important sources of care, support, advocacy and friendship for one another. We drew on online survey data from 456 UK adult siblings of people with DD. Siblings provided written responses to a prompt about their sibling experiences (> 80,000 words). These data were analysed using qualitative content analysis and organised using the Siblings Embedded Systems Framework (SESF). The SESF helps us to consider how complex interacting mechanisms and factors surrounding siblings, families and wider systems at a local, national and international level, can influence siblings' outcomes, experiences and relationships. Overall, siblings shared a range of experiences related to their: mental health and wellbeing; personal characteristics; sibling relationships; intra-familial experiences; caring experiences; experiences accessing support services; community experiences; and views on the discrimination and ableism that their disabled siblings experienced. Siblings reflected on the interconnected and dynamic nature of their experiences. We found the SESF to be a useful way of presenting an account of the data overall, as well as to explore the impact of societal factors on siblings' experiences. Siblings' structural, political and social contexts impacted their personal lives.

Women who receive a breast cancer diagnosis often have to cope with physical and psychological issues, even some years after diagnosis and treatments. Physical changes and negative inner sensations damage body image, leading to reduced contact with the body and social relationships due to shame and increased fear of cancer recurrence. Several psychological interventions have been conducted to manage psycho-emotional issues involving bodily sensations and emotions. 相似文献

Reasoning under uncertainty is the bread and butter of everyday life. Many areas of psychology, from cognitive, developmental, social, to clinical, are interested in how individuals make inferences and decisions with incomplete information. The ability to reason under uncertainty necessarily involves probability computations, be they exact calculations or estimations. What are the developmental origins of probabilistic reasoning? Recent work has begun to examine whether infants and toddlers can compute probabilities; however, previous experiments have confounded quantity and probability—in most cases young human learners could have relied on simple comparisons of absolute quantities, as opposed to proportions, to succeed in these tasks. We present four experiments providing evidence that infants younger than 12 months show sensitivity to probabilities based on proportions. Furthermore, infants use this sensitivity to make predictions and fulfill their own desires, providing the first demonstration that even preverbal learners use probabilistic information to navigate the world. These results provide strong evidence for a rich quantitative and statistical reasoning system in infants. 相似文献

Previous studies indicate that people respond defensively to threatening health information, especially when the information challenges self‐relevant goals. The authors investigated whether reduced acceptance of self‐relevant health risk information is already visible in early attention allocation processes. In two experimental studies, participants were watching high‐ and low‐threat health commercials, and at the same time had to pay attention to specific odd auditory stimuli in a sequence of frequent auditory stimuli (odd ball paradigm). The amount of attention allocation was measured by recording event‐related brain potentials (i.e., P300 ERPs) and reaction times. Smokers showed larger P300 amplitudes in response to the auditory targets while watching high‐threat instead of low‐threat anti‐smoking commercials. In contrast, non‐smokers showed smaller P300 amplitudes during watching high as opposed to low threat anti‐smoking commercials. In conclusion, the findings provide further neuroscientific support for the hypothesis that threatening health information causes more avoidance responses among those for whom the health threat is self‐relevant. 相似文献
