This qualitative research explores the interactions of elementary school students during free-choice activity with science museum exhibits. The study participants were 39 students, who visited a science museum on six occasions during a three-year-period (from 4th to 6th grades). Our study showed that most interactions around exhibits are social in nature. Within these social interactions, students mainly discuss the technicalities of operating the exhibits and rarely engage with their scientific content. On occasion, exhibits are no more than settings for social interactions that could equally occur, for example, in the schoolyard. The main implications of this study concern exhibit design and pedagogy. Because students find ways to create their own social interactions in museum settings, museum pedagogy should leverage this social interaction into cognitive engagement with the scientific content of exhibits. 相似文献

This study presents a new powerful visual illusion, in which simple “open” objects—ones with missing boundaries—are perceived as bigger than the same size, fully “closed” objects. In a series of experiments that employed a continuous-response adjustment procedure, it was found that the lack of vertical boundaries inflated the perceived width of an object, whereas the lack of horizontal boundaries inflated its perceived length. The effect was highly robust and it was replicated across different stimulus types and experimental parameters, with almost all observers exhibiting a strong effect. In contrast to the overestimation of the size of an object due to missing boundaries, the inclusion of inner boundaries within an object caused observers to underestimate its size, suggesting that filled space sometimes shrinks, rather than inflates, the perceived size of an object. The open-object illusion bears practical implications for graphics and design as well as important theoretical implications. Specifically, it indicates that the perception of an object’s area is not veridical but rather critically depends on contour closure. It is suggested that the visual system extends the missing boundaries of open contour objects, which results in an overestimation of the object’s size. 相似文献

Support for Self‐Censorship Among Israelis as a Barrier to Resolving the Israeli‐Palestinian Conflict 下载免费PDF全文

Self‐censorship, defined as an “act of intentionally and voluntarily withholding information from others in the absence of formal obstacles” often serves as a barrier to resolving intractable conflicts. Specifically, in order to protect the group, and in absence of objective constraints such as institutionalized censorship, individuals practice self‐censorship and support its practice by other society members. This prevents free flow and transparency of information, within a society, regarding the conflict and the adversary. In an attempt to investigate the factors that contribute to the functioning of self‐censorship as a sociopsychological barrier to conflict resolution, a longitudinal study was conducted among a large sample of Jews in Israel. The survey was administered in three waves: a few months before, during, and a few months after Israel's Operation Pillar of Defense in the Gaza Strip. The findings showed that armed confrontation can increase support for self‐censorship. In addition, the findings revealed that personal characteristics (e.g., authoritarianism, ethnocentrism, siege mentality) predicted support for self‐censorship, which, in turn, mediated the effect of personal characteristics on support for negotiations and for providing humanitarian aid. The theoretical as well as the applied implications of the findings are discussed. 相似文献

Individual differences in working memory ability are mainly revealed when a demanding challenge is imposed. Here, we have associated cannabinoid 1 (CB1) receptor genetic variation rs2180619 (AA, AG, GG), which is located in a potential CNR1 regulatory sequence, with performance in working memory. Two-hundred and nine Mexican-mestizo healthy young participants (89 women, 120 men, mean age: 23.26 years, SD?=?2.85) were challenged to solve a medium (2-back) vs. a high (3-back) difficulty N-back tasks. All subjects responded as expected, performance was better with the medium than the high demand task version, but no differences were found among genotypes while performing each working memory (WM) task. However, the cost of the level of complexity in N-back paradigm was double for GG subjects than for AA subjects. It is noteworthy that an additive-dosage allele relation was found for G allele in terms of cost of level of complexity. These genetic variation results support that the endocannabinoid system, evaluated by rs2180619 polymorphism, is involved in WM ability in humans. 相似文献

ABSTRACT It is undeniable that the assumption of sincerity is important to assertion, and that assertion is central to the transmission of beliefs through human testimony. Discussions of testimony, however, often assume that the epistemic importance of sincerity to testimony is that of a (fallible) guarantee of access to the actual beliefs of the speaker. Other things being equal, we would do as well or better if we had some kind of unmediated access to the beliefs of the other person, without the risks involved in the overt act of speaking, and the assumption of sincerity in speech is the closest we can come to this access. Contrary to this picture, I argue that sincerity has a quite different epistemic role to play in testimony than that of an indicator of the speaker's beliefs. The epistemology of testimony requires reference to the speaker as agent, and not just the speaker's beliefs, as well as a sense of 'expression of belief that links it to the specifically addressive relation to another person. 相似文献

When performance goals deter performance: Transfer of skills in integrative negotiations 总被引:2,自引:0,他引:2

The current study deals with the ability of teams to learn and transfer complex knowledge across situations and therefore achieve better long term performance. In an experiment on integrative (value-creating) negotiations, High Learning Teams (with learning goals, high learning values, and team discussions) and Low Learning Teams (with performance goals, low learning values, and no team discussions) participated first in a repeated integrative negotiation task and then in a new more complex one. In the first task both types of teams improved their performance over time. However, in the second transfer task, when conditions changed, High Learning Teams performed better than Low Learning Teams. Findings indicate that the High Learning Teams’ advantage cannot be attributed to the discussion alone. Furthermore, for the Low Learning Teams, negative transfer was observed: when faced with a new component, not experienced before, these teams performed worse than teams that had no experience at all. 相似文献

Some failures of selective attention may be explained by the attentional white bear (AWB) phenomenon Tsal & Makovski (Journal of Experimental Psychology: Human Perception and Performance 32:351?C363, 2006), which indicates that prior knowledge of a distractor location causes attention to be actively allocated to it. The AWB effect is demonstrated in a task that includes infrequent trials that involve two simultaneous dots embedded among flanker trials. The dot positioned at an expected distractor location is perceived as appearing before the dot at an expected empty location, indicating that attentional resources have initially been allocated to the expected distractor locations. The main goal of this study was to explore the boundaries of the AWB phenomenon by imposing perceptual, memory, and sensory constraints on the flanker task. The results showed that the AWB effect was obtained even when additional constraints severely taxed the information-processing system. We propose that a mandatory mechanism guides a fixed minimal amount of attention to expected distractor locations in a top-down manner. 相似文献

Recent research has shown that simple motor actions, such as pointing or grasping, can modulate the way we perceive and attend to our visual environment. Here we examine the role of action in spatial context learning. Previous studies using keyboard responses have revealed that people are faster locating a target on repeated visual search displays ("contextual cueing"). However, this learning appears to depend on the task and response requirements. In Experiment 1, participants searched for a T-target among L-distractors and responded either by pressing a key or by touching the screen. Comparable contextual cueing was found in both response modes. Moreover, learning transferred between keyboard and touch screen responses. Experiment 2 showed that learning occurred even for repeated displays that required no response, and this learning was as strong as learning for displays that required a response. Learning on no-response trials cannot be accounted for by oculomotor responses, as learning was observed when eye movements were discouraged (Experiment 3). We suggest that spatial context learning is abstracted from motor actions. 相似文献

Emotion dysregulation is believed to be a key factor in anxiety disorders. However, the empirical basis for this view is limited,
particularly in children and adolescents. This study aimed to examine whether anxious children display negative emotional
hyper-reactivity and deficits in emotion regulation, using a new task that presents ambiguous situations with potentially
threatening meanings. Forty-nine children diagnosed with either generalized anxiety disorder, social anxiety, or separation
anxiety disorder, were compared with 42 non-anxious controls. Relative to controls, anxious children demonstrated (a) greater
intensity and frequency of negative emotional responses, (b) deficits in using reappraisal in negative emotional situations
and corresponding deficits in reappraisal self-efficacy, and (c) greater reliance on emotion regulation strategies that increase
the risk of functional impairment, intense negative emotion, and low emotion regulation self-efficacy. Implications for the
assessment and treatment of childhood anxiety are discussed. 相似文献
