In recent years, there has been an increasing focus on the role played by basic numerical magnitude processing in the typical and atypical development of mathematical skills. In this context, tasks measuring both the intentional and automatic processing of numerical magnitude have been employed to characterize how children’s representation and processing of numerical magnitude changes over developmental time. To date, however, there has been little effort to differentiate between different measures of ‘number sense’. The aim of the present study was to examine the relationship between automatic and intentional measures of magnitude processing as well as their relationships to individual differences in children’s mathematical achievement. A group of 119 children in 1st and 2nd grade were tested on the physical size congruity paradigm (automatic processing) as well as the number comparison paradigm to measure the ratio effect (intentional processing). The results reveal that measures of intentional and automatic processing are uncorrelated with one another, suggesting that these tasks tap into different levels of numerical magnitude processing in children. Furthermore, while children’s performance on the number comparison paradigm was found to correlate with their mathematical achievement scores, no such correlations could be obtained for any of the measures typically derived from the physical size congruity task. These findings therefore suggest that different tasks measuring ‘number sense’ tap into different levels of numerical magnitude representation that may be unrelated to one another and have differential predictive power for individual differences in mathematical achievement. 相似文献

Primary care settings are the gateway through which the majority of Latinos access care for their physical and mental health concerns. This study explored the perspectives of primary care providers regarding their Latino patients, particularly, issues impacting their patients' access to and utilization of services. Interviews were conducted with eight primary care providers-and analyzed using consensual qualitative research methods. In addition, observations were conducted of the primary care setting to contextualize providers' perspectives. Providers indicated that care for Latinos was impacted by several domains: (a) practical/instrumental factors that influence access to care; (b) cultural and personal factors that shape patients' presentations and views about physical and mental health and treatment practices; (c) provider cultural competence; and (d) institutional factors which highlight the context of care. In addition to recommendations for research and practice, the need for interdisciplinary collaboration between psychology and medicine in reducing ethnic minority disparities was proposed. 相似文献

Chronic pain affects 35% to 57% of the adult population in the United States and results in billions of dollars spent annually in direct health‐care costs and lost productivity. Extensive research confirms the considerable role psychological factors play in the experience and expression of chronic pain. The author discusses implications for counseling adult clients experiencing chronic pain, specifically interventions, interdisciplinary treatment approaches, treatment planning, diversity, and ethical/legal considerations. 相似文献

Much research on cognitive development focuses either on early-emerging domain-specific knowledge or domain-general learning mechanisms. However, little research examines how these sources of knowledge interact. Previous research suggests that young infants can make inferences from samples to populations (Xu & Garcia, 2008) and 11- to 12.5-month-old infants can integrate psychological and physical knowledge in probabilistic reasoning (Teglas, Girotto, Gonzalez, & Bonatti, 2007; Xu & Denison, 2009). Here, we ask whether infants can integrate a physical constraint of immobility into a statistical inference mechanism. Results from three experiments suggest that, first, infants were able to use domain-specific knowledge to override statistical information, reasoning that sometimes a physical constraint is more informative than probabilistic information. Second, we provide the first evidence that infants are capable of applying domain-specific knowledge in probabilistic reasoning by using a physical constraint to exclude one set of objects while computing probabilities over the remaining sets. 相似文献

Many people who report paranormal sightings (e.g., Bigfoot and UFO aliens) are apparently sincere. This places many such sightings
in the category of eyewitness errors, rather than of deliberate deception. Recent research has supported this idea; in an
earlier paper, we demonstrated that paranormal beliefs are facilitated by tendencies toward attention deficit hyperactive
disorder, dissociation, and depression. These characteristics predicted specific patterns of beliefs in several paranormal
phenomena. The present research addressed the question of whether such psychological tendencies would tend to create bias
in perception and interpretation as well as in belief- in whether a person’s identification of a given stimulus as paranormal
in nature would be influenced by the same factors previously demonstrated to influence paranormal beliefs. This hypothesis
was supported. Specifically, those with dissociative tendencies were significantly more likely to identify given stimulus
items as paranormal in nature than were those with lower dissociation scores. Dissociation was further shown to be related
to paranormal beliefs, consistent with earlier findings. Results are discussed in terms of the reconfigurative dynamics known
to operate in areas of human cognition such as eyewitness identification, and in terms of the generality of those effects
to the realm of paranormal sightings. 相似文献

The goal of this study is to characterize observers’ abilities to detect gradual changes and to explore putative dissociations between conscious experience of change and behavioral adaptation to a changing stimulus. We developed a new experimental paradigm in which, on each trial, participants were shown a dot pattern on the screen. Next, the pattern disappeared and participants had to reproduce it. In some conditions, the target pattern was incrementally rotated over successive trials and participants were either informed or not of this change. We analyzed both awareness of the changes and the dynamics of behavioral adaptation, in a way that makes it possible to assess both variability and accuracy as they change over time. Results indicate a dissociation between change awareness and behavioral adaptation to the changes, and support the notion that unconscious representations of visual stimuli are more precise and detailed than previously suggested. We discuss the implications of these results for theories of change detection. 相似文献

Six pigeons were trained in a change detection task with four colors. They were shown two colored circles on a sample array,
followed by a test array with the color of one circle changed. The pigeons learned to choose the changed color and transferred
their performance to four unfamiliar colors, suggesting that they had learned a generalized concept of color change. They
also transferred performance to test delays several times their 50-msec training delay without prior delay training. The accurate
delay performance of several seconds suggests that their change detection was memory based, as opposed to a perceptual attentional
capture process. These experiments are the first to show that an animal species (pigeons, in this case) can learn a change
detection task identical to ones used to test human memory, thereby providing the possibility of directly comparing short-term
memory processing across species. 相似文献

Student-based teaching evaluations are an integral component to institutions of higher education. Previous work on student-based teaching evaluations suggest that evaluations of instructors based upon “thin slice” 30-s video clips of them in the classroom correlate strongly with their end of the term “thick slice” student evaluations. This study’s results support previous findings, but also find that thick slice student evaluations are better than thin slice evaluations. The findings are interpreted to suggest that thick slice evaluations capture course content variables not reflected in thin slice evaluations. 相似文献

In an investigation of students’ prejudicial biases against instructors who smoke, 61 female and 16 male undergraduates watched
and listened to a 20-min lecture about parasomnias, completed a survey asking for instructor evaluation ratings and ratings
of perceived learning, and completed a lecture-retention test with multiple-choice questions to assess actual learning. In
a between-subjects design, the lecture was given by either a man or woman, who was portrayed as a smoker or nonsmoker. The
instructors’ sex and smoking status did not affect the students’ perceived or actual learning (all p’s > .05). However, a significant interaction on the instructor evaluation ratings revealed that students rated the female
instructors equivalently (p = .78), but rated the smoker male instructor significantly lower than the nonsmoker male instructor (p = .01). These findings suggest that students hold prejudicial biases against male instructors who smoke, but that these biases
do not affect student learning. 相似文献
