To determine if the spatial and/or temporal context affected the coordination patterns of children under five in upright interceptive tasks, 3-year-olds hit a ball dropped from a ramp from five heights (1.5, 2, 2.5, 3, and 3.5 m) to control drop time. We studied the initiation time of hitting a ball with a cinematic analysis of the different joint movements (foot, knee, hip, shoulder, and hand). Two patterns of joint coordination were observed according to the rolling height of the ball: a de-synchronized pattern for heights of 2 m or above where the foot was the first to move and the hand the last, and a “synchronized” pattern, for the lowest height (1.5 m) where all joints started moving at the same time due to a strong temporal pressure. These two coordination patterns highlight a functional adaptation of body joints according to the spatio-temporal constraints among children from the age of three. 相似文献

In spite of the safety and efficiency of the COVID-19 vaccines and the many promotion efforts of political and expert authorities, a fair portion of the population remained hesitant if not opposed to vaccination. Public debate and the available literature point to the possible role of people's attitudes towards medical institutions as well as their preference for complementary and alternative medicine (CAM) on their motivations and intentions to be vaccinated. Other potential ideological factors are beliefs about environmental laissez-faire and divine providence insofar as they encourage people to let the pandemic unfold without human interference. In three cross-sectional samples (total N = 8214), collected at successive moments during the Belgian vaccination campaign, the present research examines the distal role of these psychological and ideological factors on vaccination intentions via motivational processes. Study 1 gauges the relation between trust in medical institutions and preference for CAM on intentions to get vaccinated via motivations. Study 2 examined the role of beliefs in the desirability of letting nature take its course (‘environmental laissez-faire beliefs’) on vaccination intention via motivations. Study 3 tests whether people's adherence to environmental laissez-faire and beliefs about divine providence are linked to their motivations for vaccination via trust in the medical institutions and CAM. Results show that adherence to CAM has a deleterious effect on vaccination intentions, whereas trust in medical institutions has a positive effect. Both ideological factors pertaining to external control are only moderately related, with environmental laissez-faire beliefs having stronger effects on CAM, medical trust and vaccination motivations. We discuss the importance of this set of results in light of the growing interest in CAM and the increasing presence of messages appealing to the environment. 相似文献

Do US findings on applicants' self‐presentational behavior generalize to other countries? We argue that applicants in some countries are less motivated to present themselves favorably than applicants in others because countries vary in their unemployment rate (leading to differences in competition between job applicants) and their endorsement of modesty values, influencing their beliefs regarding self‐presentation. Using the randomized response technique, we obtained prevalence data on applicants' self‐presentational behavior from Iceland and Switzerland and compared them with previously published US results. The prevalence rates of self‐presentational behavior were fairly comparable in Iceland and Switzerland but significantly lower than in the United States. These results caution against using the same hiring strategy for all applicants from different cultures. 相似文献

This article contributes to the understanding of why the use of a frame-of-reference leads to increased criterion-related validity of personality inventories. Two competing explanations are described and tested. A between-subjects (N = 337) and a within-subject (N = 105) study are conducted to test the hypothesized effects of use of a frame of reference on reliability and validity. Regarding the effects on reliability, use of a frame of reference reduces within-person inconsistency (instead of between-person variability) in responding to generic items. Use of a frame of reference further leads to higher validity as a result of the reduction of between-person variability and within-person inconsistency. Yet, reducing these inconsistencies is not enough. It is also important to use a frame of reference that is conceptually relevant to the criterion. Besides implications for contextualized personality inventories, these results provide an explanation for the moderate validities of generic personality inventories. 相似文献

To determine if children under 5 years were able to intercept a moving object while stepping, the authors had 9 3-year-olds hit a ball that the authors dropped from a ramp from 5 heights (1.5, 2.0, 2.5, 3.0, and 3.5 m). The statistical analysis showed that the hand movement times were similar regardless of ball rolling heights and that the hand initiation times were dependent on the ball rolling times. Children under 5 years were able to hit a moving ball, and they performed this hitting according to a temporal coupling between ball displacements and the hand contact with it. The participants' behavior of hitting while stepping supports the idea that the motor system implicitly knows what the cognitive system ignores. 相似文献

Despite the advances in understanding cognitive improvements in executive function in adolescence, much less is known about the influence of affective and social modulators on executive function and the biological underpinnings of these functions and sensitivities. Here, recent behavioral and neuroscientific studies are summarized that have used different approaches (cognition, emotion, individual differences and training) in the study of adolescent executive functions. The combination of these different approaches gives new insight into this complex transitional phase in life, and marks adolescence as not only a period of vulnerabilities, but also great opportunities in terms of training possibilities and interventions. 相似文献

We examined the vertical jump performance of each leg among 10 right-footed female ballet dancers with 1 yr. of international professional experience (quadrilles: Opera ballerinas). Their mean age was 17.5 yr. (SD=0.3). The maximal height of the unilateral jump was recorded, and muscle mass was evaluated by biphotonic absorptiometry method. Muscle mass and maximal jump height were similar for the two legs. A strong inverse relation was found between the muscle mass of the right leg (67%) and maximal jump height (r=-.81, p<.01) but not for the left leg. These results highlight a functional asymmetry and the effect of motor laterality in dance. 相似文献

This study investigated hot and cool aspects of cognitive control in children with Attention Deficit Hyperactivity Disorder (ADHD). The study aimed to: (1) replicate the postulated response inhibition deficit of children with ADHD; (2) explore whether children with ADHD choose disadvantageously in a decision-making task and to explore the mechanisms underlying the expected response pattern; and (3) study whether performance on a combination of hot and cool executive control measures has predictive value for an ADHD diagnosis. The sample consisted of 20 children with ADHD and 22 normal developing children (NC, 8 to 12 years) matched on age, FSIQ, and gender. Two paradigms have been applied: (1) the stop signal paradigm, and (2) the adapted children's version of the IOWA Gambling task. There were no group differences for both paradigms. Both groups chose in a reward-oriented manner and seemed to develop the ability to take future consequences into account in making decisions. Moreover, feedback resulted in direct behavioral changes. Children with ADHD did not have a specific response inhibition deficit or a decision-making deficit. 相似文献
