“These Pretzels Are Making Me Thirsty”: Older Children and Adults Struggle With Induced‐State Episodic Foresight 下载免费PDF全文

We explored children's and adults’ ability to disengage from current physiological states when forecasting future desires. In Study 1, 8‐ to 13‐year‐olds and adults (N = 104) ate pretzels (to induce thirst) and then predicted and explained what they would want tomorrow, pretzels or water. Demonstrating life‐span continuity, approximately 70% of participants, regardless of age, chose water and referenced current thirst as their rationale. Individual differences in working memory and undergraduate grade point average were positively related to performance on the pretzel task. In Study 2, we obtained baseline preferences from adults (N = 35) and confirmed that, prior to consuming pretzels, people do not anticipate wanting water more than pretzels the next day. Together, these findings indicate that both children and adults are tethered to the present when forecasting their future desires. 相似文献

Becoming a history teacher requires the integration of pedagogical knowledge, pedagogical content knowledge, and content knowledge. Because the integration of knowledge from different disciplines is a complex task, we investigated prompted learning journals as a method to support teacher students’ knowledge integration. Fifty-two preservice history teachers participated in the experimental study. They read a text about a historical event, a text about teaching history, and a text about cognitive learning processes. Then they wrote a learning journal entry about the three texts. To support the journal writing, the participants in the experimental condition received four integration prompts, whereas the participants in the control condition received no prompts. In the prompted condition, the students engaged more often in integration strategies at the cost of rehearsal and organization strategies. Rehearsal and integration strategies predicted students’ recall of knowledge and their ability to evaluate learning tasks. Integration strategies as elicited in the journals predicted preservice teachers’ performance when designing a learning task for history education. In solving this task, the prompted preservice teachers used the information from the three texts in a more balanced way than the unprompted students who strongly focused on content knowledge. The study illustrates the potentials of learning journals as a method to support knowledge integration in history teacher education. 相似文献

The study explores how competition-based reality shows with different thematic content influence gratifications obtained by viewers. Participants completed surveys regarding their reasons for watching reality programs in general and their reasons for watching specific reality shows (The Apprentice, The Bachelor/Bachelorette, and Survivor). Results identified a new gratification dimension not previously observed in other gratifications research (personal utility), and that correlations exist between the specific content of reality-based programs and the gratifications obtained by the viewers. 相似文献

Past research provides associations between maternal parenting behaviors and characteristics such as depression and toddlers' fearful temperament. Less is known about how maternal cognitive characteristics and normal personality relate to fearful temperament. This study examined associations among the maternal cognitive characteristic of accuracy, maternal personality, toddler gender, context, and 24-month-old toddlers' fearful temperament. Mothers were more accurate in predicting their daughters' emotional reactions in fear-eliciting contexts. High maternal approach personality was related to increased maternal accuracy for boys. High maternal approach personality, in conjunction with lower accuracy, however, was associated with higher levels of toddlers' fearful temperament. Results suggest implications for the current understanding of toddlers' fearful temperament. 相似文献

A general model of instructional communication is advanced and the linkages of four components in the model are tested. Data were drawn from college teachers and college students through a split‐class design which permitted collection of unique data from teachers and two sets of their students. Using by‐class analyses of data it was determined that teacher self‐reported temperament is significantly correlated with students' perceptions of the teachers' communication behaviors and the students' evaluation of teachers' source credibility and task attractiveness. All of these measures were also found to predict learning outcomes and teacher evaluations of another group of students. The results support the general model and provide a foundation for future research in instructional communication. 相似文献

In a two-choice discrimination learning paradigm, a U-shaped function was found between trials to criterion and the number of sides comprising the random figure discriminanda. These data are consistent with results from human Ss and suggest similar information processing capabilities in the two species. Changing the orientation of the stimulus figures after the discrimination had been learned only partially disrupted subsequent discrimination performance. Any single difference in selected form attributes between the two figures comprising a problem was not a good predictor of learning speed, suggesting that monkeys use a combination of such factors. 相似文献

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the “surface” method, the “frontier” method, the “binding-score” method, and the “fuzzy instrumental variables” method. This article uses a series of simulations to evaluate the relative performance of each of these four methods under a variety of different data-generating models. Focusing on a two-rating RDD (2RRDD), we compare the methods in terms of their bias, precision, and mean squared error when implemented as they most likely would be in practice—using optimal bandwidth selection. We also apply the lessons learned from the simulations to a real-world example that uses data from a study of an English learner reclassification policy. Overall, this article makes valuable contributions to the literature on MRRDDs in that it makes concrete recommendations for choosing among MRRDD estimation methods, for implementing any chosen method using local linear regression, and for providing accurate statistical inferences. 相似文献

Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience—within a learning session and over development—influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4–11 years) and adults searched for rewards hidden in locations with predetermined probabilities. In Experiment 1, children (n = 42) and adults (n = 32) changed strategies to maximize reward receipt over time. However, adults demonstrated greater strategy change efficiency. Making the predetermined probabilities more difficult to learn (Experiment 2) delayed effective strategy change for children (n = 39) and adults (n = 33). Taken together, these data characterize how children and adults alike react flexibly and change behavior according to incoming information. 相似文献

The aim of this article is to explore how male students learn to practice nursing and the role of technology in their training process. The study is inspired by Bruno Latour's understanding of social interaction as an interplay between humans and technology. The students' use of the washcloth and the stethoscope, two significant nursing tools, is examined. Data were gathered using participant observation and informal conversation with a group of male Norwegian nursing students and their male teacher in a skills laboratory at University College. The article contributes a renewed understanding of gender and nursing education as well as a deepened understanding of how men adjust to a historically female profession such as nursing. 相似文献

Children around 4, 5, and 7 years old (N = 48) listened to scenarios depicting a child alone or accompanied by another person (mother, father, friend) who encounters an entity that looks like a real or an imaginary fear‐inducing creature. Participants predicted and explained each protagonist’s fear intensity and suggested coping strategies. Results showed age‐related increases in judgments that different people will experience different intensities of fear in the same situation. With age, children also demonstrated increasing knowledge that people’s minds can both induce and reduce fear, especially in situations involving imaginary creatures. Suggestions of reality affirmation strategies (e.g., reminding oneself of what is real vs. not real) significantly increased with age, whereas positive pretense strategies (e.g., imagining it is a friendly ghost) significantly decreased. 相似文献
