When incorporating the environment into mental processing (cf., cognitive offloading), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university.1 Although cognitive offloading has frequently been associated with improved performance, it is yet unclear how flexible problem solvers are at matching their offloading habits with their current performance goals (can people improve goal‐related instead of generic performance, e.g., when being in a hurry and aiming for a “quick and dirty” solution?). Here, we asked participants to solve a cognitive task, provided them with different goals—maximizing speed (SPD) or accuracy (ACC), respectively—and measured how frequently (Experiment 1) and how proficiently (Experiment 2) they made use of a novel external resource to support their cognitive processing. Experiment 1 showed that offloading behavior varied with goals: Participants offloaded less in the SPD than in the ACC condition. Experiment 2 showed that this differential offloading behavior was associated with high goal‐related performance: fast answers in the SPD, accurate answers in the ACC condition. Simultaneously, goal‐unrelated performance was sacrificed: inaccurate answers in the SPD, slow answers in the ACC condition. The findings support the notion of humans as canny offloaders who are able to successfully incorporate their environment in pursuit of their current cognitive goals. Future efforts should be focused on the finding's generalizability, for example, to settings without feedback or with high mental workload. 相似文献

Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus. 相似文献

Anecdotal reports suggest that children often outperform adults when playing Concentration. This is surprising as cognitive processes tend to develop progressively throughout childhood. To date, very few studies have examined this apparent paradox, and with mixed results. In the present study, the ability of 6-year-olds (n = 34), 8-year-olds (n = 48), and adults (n = 38) to play Concentration was examined in a controlled computer-based setup involving eye tracking. The main dependent variables were the number of moves and time in seconds to finish the first nine (out of 12) matching pairs. The results revealed that while 6-year-olds were outperformed by older children and adults, 8-year-olds performed just as well as adults. It is suggested that Concentration may represent a cognitive challenge rarely encountered in the real world, and when playing Concentration, adults seem to use strategies that are effective in real life situations, but may be less appropriate when playing the game. 相似文献

Beliefs about stability and change are captured by individuals’ implicit theories. Incremental‐theorists believe that human traits and world‐dispositions are malleable and can change through effort, whereas entity‐theorists believe that human traits and world‐dispositions are fixed. In this research we find that the implicit theory an individual holds influences an important aspect of the cognitive process, namely, the level of construal at which information is processed. In three studies we demonstrate that, compared to entity‐theorists, incremental‐theorists adopt a more abstract level of information construal, and the increased cognitive flexibility afforded by an incremental‐theory mindset explains this effect. 相似文献

IntroductionGiven that diabetes is a major public heath issue around the world, it is vital that we find effective means to change behaviors, especially levels of physical activity among type 2 diabetes patients.ObjectiveThis study aims to provide proof of the effectiveness of programs promoting physical activity, based on cognitive dissonance and normative focus theories which are designed to produce behavioral changes in persons with type 2 diabetes.MethodNinety-six type 2 diabetes patients were assigned to one of three programs: a traditional information program, a norm-based program, and a dissonance-based program. The participants filled out a short French version of the International Physical Activity Questionnaire (IPAQ) one week before and one week after the program.ResultsThe results showed that the participants in the norm-based program made progress compared to those in the traditional information program. No significant difference was observed between the traditional information program and dissonance-based program.ConclusionsThese findings are consistent with both the focus normative theory and previous studies showing that recalling the norm increases compliance. The procedure to be used in diabetes prevention programs should focus on the normative dimensions of the desired behaviors in order to improve patients’ quality of life. 相似文献

Infants employ sophisticated mechanisms to acquire their first language, including some that rely on taking the perspective of adults as speakers or listeners. When do infants first show awareness of what other people understand? We tested 14‐month‐old infants in two experiments measuring event‐related potentials. In Experiment 1, we established that infants produce the N400 effect, a brain signature of semantic violations, in a live object naming paradigm in the presence of an adult observer. In Experiment 2, we induced false beliefs about the labeled objects in the adult observer to test whether infants keep track of the other person's comprehension. The results revealed that infants reacted to the semantic incongruity heard by the other as if they encountered it themselves: they exhibited an N400‐like response, even though labels were congruous from their perspective. This finding demonstrates that infants track the linguistic understanding of social partners. A video abstract of this article can be viewed at https://youtu.be/pQUv8yFhnbk . 相似文献

This study examined similarities and differences in the cognitive profiles of older adult instrumental musicians and non-musicians. We compared neuropsychological test scores among older adult non-musicians, low-activity musicians (<10 years of lessons), and high-activity musicians (≥10 years of lessons), controlling for self-reported physical and social activity, years of education, and overall health. Significant differences among groups were found on tasks of visual spatial ability, naming, and executive functioning. No significant differences were found on tests of attention/processing speed, or episodic memory. The current study supports late life cognitive benefits of early musical training, but only in select cognitive domains, including language, executive functioning, and visual spatial ability. The results are discussed in the context of cognitive reserve and aging. 相似文献

Despite the growing interest in the Internet-of-Things, many organizations remain reluctant to integrating things into their business processes. Different reasons justify this reluctance including things’ limited capabilities to act upon the cyber-physical surrounding in which they operate. To address this specific limitation, this paper examines thing empowerment with cognitive capabilities that would make them for instance, selective of the next business processes in which they would participate. The selection is based on things’ restrictions like limitedness and goals to achieve like improved reputation. For demonstration purposes, water leaks are used as a case study. A BPEL-based business process driving the fixing of water leaks is implemented involving different cognitive things like moisture sensor. 相似文献

ABSTRACTIn recent years there has been a resurgence of public discourse about the role of tolerance as one of the key elements of the Western philosophical heritage. The fact that Western societies remain largely oblivious to the importance and benefits of diversity points to the pitfalls of the liberal model of religious toleration. Jakob De Roover’s monograph ‘Europe, India, and the Limits of Secularism’ offers a new analysis of the deficiencies of secularism and demonstrates why its application to other societies, such as India, is a problematic enterprise. This article argues that Comparative Political Theory has the potential to help forge new conceptual categories and analytical tools that can be utilized to explore diverse modes of tackling religious diversity and fostering tolerance. 相似文献

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study. 相似文献
