Age Differences in Future Orientation and Delay Discounting 总被引：1，自引：0，他引：1
Laurence Steinberg Sandra Graham Lia O'Brien Jennifer Woolard Elizabeth Cauffman and Marie Banich 《Child development》2009,80(1):28-44
Age differences in future orientation are examined in a sample of 935 individuals between 10 and 30 years using a delay discounting task as well as a new self-report measure. Younger adolescents consistently demonstrate a weaker orientation to the future than do individuals aged 16 and older, as reflected in their greater willingness to accept a smaller reward delivered sooner than a larger one that is delayed, and in their characterizations of themselves as less concerned about the future and less likely to anticipate the consequences of their decisions. Planning ahead, in contrast, continues to develop into young adulthood. Future studies should distinguish between future orientation and impulse control, which may have different neural underpinnings and follow different developmental timetables. 相似文献

Children between the ages of 5 and 10 years watched a videotape of a child having a routine medical exam. Embedded within the scenes were systematic variations of depicted facial affect shown by doctor and child. Measures were taken of autonomic reactions and information-processing errors in response to positive, neutral, and negative affective cues. For 5-6-year-olds, processing errors were greatest in the negative affect condition. Additionally, peak increases in heart rate (HR) and skin conductance level (SCL) were demonstrated by 5-6-year-olds in response to negative affect shown by the witnessed child; increases in HR were in turn predictive of processing errors. Older children (9-10 years) showed trends reflecting reduced processing errors in response to witnessed negative affect. It was suggested that younger children respond to salient threat cues with a "defensive" response pattern that is relatively adaptive at younger but not older ages. 相似文献

A series of studies was conducted to examine the development of self-evaluation in children aged 1-5 years. Developmental changes in children's reactions to achievement-related outcomes were assessed in a variety of contexts, using different tasks and different criteria for success. The first study of 1-3-year-olds revealed an increased social orientation after the age of 21 months. Only children over this age were more likely to look up at the experimenter after they had produced an outcome themselves than after the same outcome had been produced by the experimenter. These older children were also more likely than younger children to call their mothers' attention to their achievements in a free-play situation. In a second study, on a task with visibly salient success versus failure outcomes, children aged 2-5 years responded to success with positive affect (e.g., smiling) and to failure with avoidance reactions (e.g., looking away from the experimenter). Praise enhanced children's positive affective reactions to success, but its effect was modest. In the final study, winning or losing on a competitive task was not understood by children below age 33 months and had no effect on their affective reactions to the task. In contrast, winning enhanced older children's pleasure in completing the task. Three stages are proposed in the development of self-evaluation. In the first stage, children experience joy in causality, but they lack the cognitive representational skills required for self-evaluation in a self-reflective sense, and they do not anticipate others' reactions to their performance. In the second stage, beginning before the age of 2 years, children anticipate adult reactions, seeking positive reactions to their successes and endeavoring to avoid negative reactions to failure. The proposed third stage involves a gradual internalization of external reactions, with children beginning to evaluate their performance and react emotionally to success and failure independently of their expectations of adult reactions. Although all studies focused on achievement outcomes, the development of self-evaluation in the moral domain may parallel this developmental sequence proposed for the achievement domain. It is also proposed that caretakers' reactions to rule violations might engender concerns about meeting adult expectations in achievement contexts. 相似文献

Physiological reactivity to responsive and unresponsive children as moderated by perceived control 总被引：2，自引：0，他引：2
80 undergraduate women, pretested on the Parent Attribution Test (PAT), watched videotapes of responsive and unresponsive children in anticipation of subsequent interaction with them. Physiological measures (heart rate, skin temperature, and skin conductance) were monitored as subjects viewed videotapes and during a postinterview. Subjects who perceived caregiving failure as uncontrollable (on the PAT) were significantly more reactive to variations in child responsiveness than were those who perceived failure as controllable. The highest level of arousal (elevated heart rate and skin conductance) was manifested by "low-control" women anticipating interaction with unresponsive children. The increased arousal level shown in reaction to unresponsive children was accompanied by decreased skin temperature--suggesting the presence of fear or anxiety. Results were interpreted as indicating the importance of social cognitions as moderators of caregiver response to child behavior. 相似文献

Out-of-home placement decision-making in child welfare is founded on the best interest of the child in the least restrictive setting. After a child is removed from home, however, little is known about the mechanism of placement decision-making. This study aims to systematically examine the patterns of out-of-home placement decisions made in a state's child welfare system by comparing two models of placement decision-making: a multidisciplinary team decision-making model and a clinically based decision support algorithm. Based on records of 7816 placement decisions representing 6096 children over a 4-year period, hierarchical log-linear modeling characterized concordance or agreement, and discordance or disagreement when comparing the two models and accounting for age-appropriate placement options. Children aged below 16 had an overall concordance rate of 55.7%, most apparent in the least restrictive (20.4%) and the most restrictive placement (18.4%). Older youth showed greater discordant distributions (62.9%). Log-linear analysis confirmed the overall robustness of concordance (odd ratios [ORs] range: 2.9–442.0), though discordance was most evident from small deviations from the decision support algorithm, such as one-level under-placement in group home (OR = 5.3) and one-level over-placement in residential treatment center (OR = 4.8). Concordance should be further explored using child-level clinical and placement stability outcomes. Discordance might be explained by dynamic factors such as availability of placements, caregiver preferences, or policy changes and could be justified by positive child-level outcomes. Empirical placement decision-making is critical to a child's journey in child welfare and should be continuously improved to effect positive child welfare outcomes. 相似文献

Age‐related differences in temporal discounting (TD) and risk taking, and their association, were examined in adolescents and young adults (n = 337) aged 12–27 years. Since monetary rewards are typically used in TD and risk‐taking tasks, the association between monetary reward valuation and age and decision making in these tasks was explored as well. TD declined linearly with age, with a particularly sharp decline from 15 to 16 years. In contrast, risk taking was not correlated with age and TD. Reward valuation was not associated with TD and risk taking, and age‐related differences in TD remained significant after controlling for reward valuation. Together, these findings suggest that risk taking and TD are two separate constructs with distinct age‐related differences in adolescence and young adulthood. 相似文献

To a large extent, creativity is a decision. Children as well as adults are creative, not by virtue of an innate ability, but by virtue of a set of decisions. In essence, they decide for creativity, rather than an innate set of abilities deciding whether they are creative. Thus, creative giftedness is not a fixed trait, but a decision‐making skill that can be developed. In this article, I present ten decisions people can make to decide for creativity. Included are teaching examples of these decisions as well as teaching activities to facilitate students' learning how to make these decisions. 相似文献

The goal of this study was to examine the relations of reactive versus proactive aggression to children's anger, as assessed using observational, physiological, and self-report measures. Anger was hypothesized to be related to reactive aggression, but not to proactive aggression. Children (N = 272 second-grade boys and girls) participated in a procedure in which they lost a board game and prize to a confederate who cheated. Skin conductance reactivity and heart rate reactivity were measured throughout the procedure. Following the interaction, children viewed a videotape of the game and self-reported on their level of anger after each turn of the game. Observational coding of children's angry facial expressions and angry nonverbal behaviors was conducted. Reactive aggression, but not proactive aggression, was positively related to skin conductance reactivity and angry nonverbal behaviors, both at an aggregated level and in terms of rate of increase over the time span of the game. 相似文献

Intelligence gathering, or data collection, is a preliminary and critical stage of decision making. Two key approaches to intelligence gathering are “discovery” and “idea imposition.” The discovery approach allows us to learn about possibilities by gathering intelligence in order to identify and weigh options. The idea imposition approach limits intelligence gathering and focuses resources on promoting a solution. The purpose of this study is to explore the intelligence‐gathering stage of organizational leaders during decision making from both of these perspectives and to begin to identify themes as they relate to the data considered, types of decisions and outcomes sought, and level of confidence in decision‐making success. 相似文献

The idea of students participating in decisions that affect them as individuals, organisations and/or communities is recent and urgent. The participation of students in decision making has gained global support, yet it does not seem to be regarded as a main vehicle for promoting democracy in educational institutions. This conceptual paper aims at demonstrating the difficulties perceived to hinder student participation in educational institutions. It further proposes strategies that may favour the increased and improved involvement of students in decision making processes. The reviewed literature on student participation informing this article highlights positive outcomes from engaging students as decision makers in education. 相似文献

This research examined the role of children’s decision‐making autonomy in their emotional functioning during early adolescence in the United States and China. Four times over the 7th and 8th grades, 825 American and Chinese children (M = 12.73 years) reported on the extent to which they versus their parents make decisions about issues children often deem as under their authority. Children also reported on their emotional functioning. American children made greater gains over time in decision‐making autonomy than did Chinese children. Initial decision‐making autonomy predicted enhanced emotional functioning similarly among American and Chinese children. However, gains over time in decision‐making autonomy predicted enhanced emotional functioning more in the United States (vs. China) where such gains were normative. 相似文献

To have insight into cognitive load (CL) during online complex problem solving, this study aimed at measuring CL through physiological data. This study experimentally manipulated intrinsic and extraneous load of exercises in the domain of statistics, resulting in four conditions: high complex with hints, low complex with hints, high complex without hints and low complex without hints. The study had a within-subject-design in which 67 students solved the exercises in a randomized order. Self-reported CL was combined with physiological data, namely, galvanic skin response (GSR), skin temperature (ST), heart rate (HR) and heart rate variability (HRV). Multiple imputation was used for handling missing data from resp. 16 and 19 students for GSR/ST and HR/HRV. First, differences between conditions in view of physiological data were examined. Second, we investigated how much variance of self-reported CL and task performance was explained by physiological data. Finally, we investigated which features can be used to assess (objective) CL. Results revealed no significant differences between the manipulated conditions in terms of physiological data. Nonetheless, HR and ST were significantly related to self-reported CL, whereas ST to task performance. Additionally, this study revealed the potential of ST and HR to assess high CL. 相似文献

There has been considerable research concerning peer interaction and the acquisition of children’s scientific reasoning. This study investigated differences in collaborative activity between pairs of children working around a computer with pairs of children working with physical apparatus and related any differences to the development of children’s scientific reasoning. Children aged between 9 and 10 years old (48 boys and 48 girls) were placed into either same ability or mixed ability pairs according to their individual, pre-test performance on a scientific reasoning task. These pairs then worked on either a computer version or a physical version of Inhelder and Piaget’s (1958) chemical combination task. Type of presentation was found to mediate the nature and type of collaborative activity. The mixed-ability pairs working around the computer talked proportionally more about the task and management of the task; had proportionally more transactive discussions and used the record more productively than children working with the physical apparatus. Type of presentation was also found to mediated children’s learning. Children in same ability pairs who worked with the physical apparatus improved significantly more than same ability pairs who worked around the computer. These findings were partially predicted from a socio-cultural theory and show the importance of tools for mediating collaborative activity and collaborative learning. 相似文献

This study investigated the effect of individual differences in state anxiety on tasks tapping the central executive, phonological, and visuo‐spatial components of working memory (WM). It was designed to test Eysenck and Calvo’s processing efficiency theory (PET) which suggests that the phonological and executive components of WM may be important in understanding learning outcomes in anxiety. Typically‐developing children aged 9–10 years were split into high and low state anxiety groups. They performed three WM tasks – forward and backward digit span (assumed to measure phonological and central executive components of WM respectively) and a spatial working memory task (measuring the visuo‐spatial component of WM). Measurements of task accuracy were taken as an indicator of performance outcome or effectiveness. Time taken to complete tasks and a subjective rating of mental effort were taken as measurements of performance efficiency. No differences were found between high and low state anxiety groups in task accuracy for any measure. Children in the high state anxiety group, however, took longer to complete the backward digit span task and reported increased mental effort in the forward digit span task, indicating some effect of anxiety on measures of performance efficiency. 相似文献

This article applies Engeström's Activity Theory (AT) as an analytical lens to identify defining characteristics of the collaborative creative music making activities of composing and arranging. Attention is paid to the complex interrelationships among the various elements of interaction in children's collaborative creative music making as evidenced in group composing (where the activity features generation and revision of new musical material) and arranging (where the activity features creative use of existing musical material) are differentiated tasks. These include, for example, tool use in response to different tasks, the rules that govern peer collaboration, and the division of labour experienced among key players in the co-construction of decisions. Exemplary cases are sampled from data sets drawn from two separate sites one of which features a group composing task with fifth graders in a USA urban school and the other a group arranging task with eighth graders in a UK urban school. This micro-analysis is less concerned with the differences of collaborative interaction in varying cultural settings than with exploring the micro-analysis of social and language processes that characterise these differentiated creative tasks and the related activity systems. The activity system, or systems of social relations, is the unit of analysis applied across comparison-group cases using ethnographic observation, and discourse and event analysis. Analysis of the data indicates that composing and arranging involve differentiated activity systems. Important defining characteristics of the collaborative interactions, as outcomes of the children's approach to the task activities, are identified. Conclusions indicate that the application of an activity theory research perspective can provide a useful framework to make sense of the interrelated elements that characterise interaction in peer collaboration. 相似文献

Two major frameworks for educational decision making, including decisions on assessment, can be distinguished: quantitative, whichis adequate for construing some kinds of learning; and qualitative, which should be the appropriate framework for enabling decisions flowing from most tertiary educational aims. However, for various reasons, institutions implicitly encourage a quantitative framework for assessment‐related decision making, particularly evident in the recent emphasis on accountability and performance indicators. This is unfortunate because, through the backwash effect, quantitative modes of assessment encourage surface approaches to learning, which typically lead to low cognitive‐level outcomes that are not compatible with stated course objectives. It is argued that an institution and its educational practices comprise a system in equilibrium, and that if educational goals are to be realised, the whole system needs to be compatible with those aims. 相似文献

This study explored the judgments and reasoning of Chinese adolescents (13-18 years of age) from 3 regions of mainland China (N = 574) regarding procedures for making decisions involving children in peer, family, and school contexts. Participants evaluated 2 democratic decision-making procedures (majority rule and consensus) and decision making by adult authorities for 2 decisions embedded in each social context. Judgments and reasoning about decision-making procedures varied by social context and by the decision under consideration, and evaluations of procedures became more differentiated with increasing age. The findings reveal that concepts of rights, individual autonomy, and democratic norms (majority rule) are salient aspects of Chinese adolescents' social reasoning and are used to evaluate critically existing social practices. 相似文献

The primary purpose of the present study was to examine age differences in choice deferral when young and older adults make high vs. low conflict decisions in two domains (i.e., health and commodity). Sixty young and 60 older adults were presented with four different decision scenarios in which they could either choose an option or use choice deferral (i.e., not choose any of the options for the time being). The high conflict decisions had negative interattribute correlations, while the low conflict decisions had positive interattribute correlations. Older adults were more likely than young adults to choose the deferral option across domains. Participants were more likely to choose the deferral option when making high conflict decisions than when making low conflict decisions. For older adults, an increase in postdecision positive affect was greater for those who deferred choice than for those who did not defer choice in the commodity domain. Implications were discussed in terms of real-life decision making of older adults. 相似文献

Monitoring refers to online awareness and self-evaluation of one's goal-directed actions, while Control refers to the generation and selection of goal-directed actions (Osman, 2010a). The present study examines the extent to which external estimations of performance influence monitoring and control behaviors. To achieve this, a complex dynamic decision making task was used in which three different cues were manipulated in order to control three outcomes. The experiment was divided into two conditions. The Externally guided-condition received information designed to influence people's evaluation of control performance, whereas the Self-guided-condition was not provided this information. The findings revealed that control performance differed according to whether the success of one's actions was evaluated against external or self-guided estimations of performance. This article proposes that Monitoring behaviors can strongly influence control behaviors and this is achieved according to the way in which outcomes of decisions are evaluated. Finally, with respect to adult learning, the findings from this study suggest that setting one's own goals do not lead to improvements in learning when the task is a complex one. 相似文献

Value-based decisions often involve comparisons between benefits and costs that must be retrieved from memory. To investigate the development of value-based decisions, 9- to 10-year olds (N = 30), 11- to 12-year olds (N = 30), and young adults (N = 30) first learned to associate gain and loss magnitudes with symbols. In a subsequent decision task, participants rapidly evaluated objects that consisted of combinations of these symbols. All age groups achieved high decision performance and were sensitive to gain–loss magnitudes, suggesting that required core cognitive abilities are developed early. A cognitive-modeling analysis of performance revealed that children were less efficient in object evaluation (drift rate) and had longer nondecision times than adults. Developmental differences, which emerged particularly for objects of high positive net value, were linked to mnemonic and numerical abilities. 相似文献
