Conscious Control Is Associated With Freezing of Mechanical Degrees of Freedom During Motor Learning
Wouter F. van Ginneken Jamie M. Poolton Catherine M. Capio John van der Kamp Cynthia S. Y. Choi Richard S. W. Masters 《Journal of motor behavior》2018,50(4):436-456
This study investigated whether conscious control is associated with freezing of mechanical degrees of freedom during motor learning. Participants practiced a throwing task using either error-strewn or error-reduced practice protocols, which encourage high or low levels of conscious control, respectively. After 24 hr, participants engaged in a series of delayed retention and transfer tests. Furthermore, propensity for conscious control was assessed using participants' ratings and freezing was gauged through movement variability of the throwing arm. Performance was defined by mean radial error. In the error-strewn group, propensity for conscious control was positively associated with both freezing and performance. In the error-reduced group, propensity for conscious control was negatively associated with performance, but not with freezing. These results suggest that conscious control is associated with freezing of mechanical degrees of freedom during motor learning. 相似文献

Salience Versus Proportional Reasoning: Rethinking the Mechanism Behind Graphical Display Effects 下载免费PDF全文
Two experiments examined predictions from two separate explanations for previously observed display effects for communicating low‐probability risks: foreground:background salience and proportional reasoning. According to foreground:background salience, people's risk perceptions are based on the relative salience of the foreground (number of people harmed) versus the background (number of people at risk), such that calling attention to the background makes the risk seem smaller. Conversely, the proportional reasoning explanation states that what matters is whether the respondent attends to the proportion, which conveys how small the risk is. In Experiment 1, we made the background more salient via color and bolding; in contrast to the foreground:background salience prediction, this manipulation did not influence participants' risk aversion. In Experiment 2, we separately manipulated whether the foreground and the background were displayed graphically or numerically. In keeping with the proportional reasoning hypothesis, there was an interaction whereby participants given formats that displayed the foreground and background in the same modality (graphs or numbers, thereby making the proportion easier to form) saw the probability as smaller and were less risk averse than participants given the information in different modalities. There was also a main effect of displaying the background graphically, providing some support for foreground:background salience. In total, this work suggests that the proportional reasoning account provides a good explanation of many display effects related to communicating low‐probability risks, although there is some role for foreground:background salience as well.

People often have erroneous knowledge about the world that is firmly entrenched in memory and endorsed with high confidence. Although strong errors in memory would seem difficult to “un-learn,” evidence suggests that errors are more likely to be corrected through feedback when they are originally endorsed with high confidence compared to low confidence. This hypercorrection effect has been predominantly studied in laboratory settings with general knowledge (i.e., trivia) questions, however, and has not been systematically explored in authentic classroom contexts. In the current study, college students in an introductory horticulture class answered questions about the course content, rated their confidence in their answers, received feedback of the correct answers, and then later completed a posttest. Results revealed a significant hypercorrection effect, along with a tendency for students with higher prior knowledge of the material to express higher confidence in, and in turn more effective correction of, their error responses. 相似文献

Difficulties with emotion regulation are a core feature of anxiety disorders (ADs) in children and adults. Interventions with a specific focus on emotion regulation are gaining empirical support. Yet, no studies to date have compared the relative efficacy of such interventions to existing evidence-based treatments. Such comparisons are necessary to determine whether emotion-focused treatments might be more effective for youth exhibiting broad emotion-regulation difficulties at pretreatment. This study examined an emotion-focused cognitive-behavioral therapy (ECBT) protocol in comparison to traditional cognitive-behavioral therapy (CBT) in a sample of children with a primary anxiety disorder diagnosis. Moderation analyses examined whether children with higher levels of emotion dysregulation at pretreatment would show greater levels of improvement in ECBT than CBT. Ninety-two youth ages 7 to 12 years (58% male) with a primary diagnosis of separation anxiety disorder, generalized anxiety disorder, or social phobia were included. Participants were randomly assigned to ECBT or CBT. Results showed that youth in both conditions demonstrated similar improvements in emotion regulation and that pretreatment levels of emotion dysregulation did not moderate treatment outcomes. Additional analyses showed that ECBT and CBT were similarly effective on diagnostic, severity, and improvement measures. Future work is needed to further explore the ways that emotion regulation is related to treatment outcome for anxious youth. 相似文献

The absence of validated U.S. rates of nonfatal suicidal behavior places risk management and injury prevention programs at danger of being poorly informed and inadequately conceptualized. In this study we compare estimated rates of intentional self-harm from two ongoing surveys (National Electronic Injury Surveillance System-All Injury Program-NEISS-AIP; National Hospital Ambulatory Medical Care Survey-NHAMCS) to data from the Toxic Exposure Surveillance System. Results suggest that, for every 2002-2003 suicide, there were 12 (NEISSAIP) or 15 (NHAMCS) self-harm-related emergency department visits, and for every intentional self-poisoning death there were 33 intentional overdoses reported to poison control centers, of which two ultimately went untreated. 相似文献

Prior research on age and emotions has found that older adults may show better physiological regulation to stressful stimuli than do younger adults. However, the stress reactivity literature has shown that age is associated with higher cardiovascular reactivity to laboratory stress (J. R. Jennings et al., 1997). The authors investigated these conflicting findings further by examining daily ambulatory blood pressure in 428 middle-aged to older adults. Consistent with the age and reactivity literature, relatively old individuals showed significantly greater increases in ambulatory diastolic blood pressure compared with younger individuals when dealing with daily stressors. However, results also revealed that relatively old individuals reported less of an increase in negative affect during daily stress compared with their younger counterparts. The results of this study are consistent with the age-related increase in cardiovascular risk but highlight the complex links between stress and different facets of the aging process. 相似文献
