Although a great deal of experimental attention has been directed at understanding Fitts' law, only a limited number of experiments have attempted to determine if performance differs across effectors for a given movement difficulty. In three experiments reciprocal wrist and arm movements were compared at IDs of 1.5, 3, 4.5 and 6. When absolute movement requirements and visual display were constant, participants' movement times and response characteristics for the arm and wrist were remarkably similar (Experiment 1). However, when amplitude for wrist movements was reduced to 8° and the gain (4×) for the visual display increased participants' movement time, defined on the basis of kinematic markers (movement onset − movement termination), was increasingly shorter relative to arm movements as movement difficulty was increased (Experiment 2). Experiment 3 where the arm was tested at 32° and 8° with the 8° movements provided the same gain (4×) that was used for the 8° wrist movements in Experiment 2, no advantage was observed for the arm at the shorter amplitude. The results are interpreted in terms of the advantages afforded by the increased gain of the visual display, which permitted the wrist, but not the arm, to more effectively preplan and/or correct ongoing movements to achieve the required accuracy demands. It was also noted that while the wrist was more effective during the actual movement production this was accompanied by an offsetting increase in dwell time which presumably is utilized to dissipate the forces accrued during movement production and plan the subsequent movement segment. 相似文献

Previous research has shown that certain interviewer behaviors can evoke inaccurate answers by children. In the current study, we examined the effects of approving and disapproving statements on the accuracy of 3 children's answers to questions in an interview (Experiment 1). We then evaluated 3 questioning techniques that may be used by interviewers during a forensic interview in which a child provides eyewitness testimony (Experiment 2). All participants responded with more inaccurate answers when approving statements followed inaccurate information and disapproving statements followed accurate information in Experiment 1. During Experiment 2, 1 participant responded most inaccurately when she was requestioned after providing an initial answer, whereas the remaining 2 participants responded most inaccurately when the interviewer provided cowitness information and suggestive questions. 相似文献

Previous research has shown that imagined perspective rotations elicit spatial and low-level cortical motor areas of the brain when participants rely on knowledge of their physical body, or body percept (Wraga, Flynn, Boyle, & Evans, 2010). The current study used functional magnetic resonance imaging (fMRI) to investigate whether recruitment of the body percept would activate low-level cortical motor areas of the brain within other classes of mental transformations. Participants performed imagined object and perspective rotations of three-dimensional Shephard-Metzler (1971) stimuli. For each task, participants used button presses serving as virtual pointers to locate a prescribed portion of the stimuli with respect to their "right" and "left." We found low-level cortical motor activation (M1) for both mental transformations; however, the degree to which such activation related to participants' performance differed, as well as the recruitment of additional nonmotoric strategies. The results are discussed in terms of recent hypotheses regarding the role of the body percept in extrinsically encoded mental transformations. 相似文献

Although materials informing parents about children’s mental health (CMH) problems can improve outcomes, we know relatively
little about the design factors that might influence their utilization of available resources. We used a discrete choice conjoint
experiment to model the information preferences of parents seeking mental health services for 6 to 18 year olds. Parents completed
30 choice tasks presenting experimentally varied combinations of 20 four-level CMH information content, transfer process,
and outcome attributes. Latent class analysis revealed three segments with different preferences. Parents in the Action segment
(43%) chose materials providing step-by-step solutions to behavioral or emotional problems. They preferred weekly meetings
with other parents and coaching calls from a therapist. The Information segment (41%) chose materials helping them understand
rather than solve their child’s problems. These parents were more sensitive to logistical factors such as receiving information
in groups, the location where information was available, the modality in which the information was presented, and the time
required to obtain and use the information. The Overwhelmed segment (16%) reported more oppositional and conduct problems,
felt their children’s difficulties exerted a greater adverse impact on family functioning, and reported higher personal depression
scores than those in the Action or Information segments. Nonetheless, they did not choose information about, or solutions
to, the problems their children presented. Simulations predicted that maximizing utilization and realizing the potential benefits
of CMH information would require knowledge transfer strategies consistent with each segment’s preferences.

Studies were conducted to assess driver acceptance of and trust in distraction mitigation strategies. Previous studies have shown that in-vehicle tasks undermine driver safety, and that there is a need for strategies to reduce the effects of in-vehicle distractions. Trust and acceptance of such strategies strongly influence their effectiveness. Different strategies intended to reduce distraction were categorized in a taxonomy. Focus groups were conducted to help refine this taxonomy and explore driver acceptance issues related to these strategies. A driving simulator experiment was then conducted using two of the strategies: an advising strategy that warns drivers of potential dangers and a locking strategy that prevents the driver from continuing a distracting task. These strategies were presented to 16 middle-aged and 12 older drivers in two modes (auditory, visual) with two levels of adaptation (true, false). Older drivers accepted and trusted the strategies more than middle-aged drivers. Regardless of age, all drivers preferred strategies that provided alerts in a visual mode rather than an auditory mode. When the system falsely adapted to the road situation, trust in the strategies declined. The findings show that display modality has a strong effect on driver acceptance and trust, and that older drivers are more trusting and accepting of distraction mitigation technology even when it operates imperfectly. 相似文献

This study uses information collected on two occasions from a probability sample of families with 5- to 12-year-old children (N = 1151) participating in a general population study in 1983 and follow-up in 1987. It evaluated the importance of maternal bias in the assessment of child behavior by comparing the relative strengths of association between maternal depression and childhood behavior and between maternal depression and mother reporting errors. Conduct problems and hyperactivity were measured as latent criterion variables constructed from mother, teacher, and youth (aged 12 to 16 years) ratings and their associations with maternal depression were modeled using covariance structure analysis. The analyses revealed that maternal depression was associated significantly with conduct problems ( = .35) and hyperactivity ( = .38) among 5- to 7-years-olds in 1983 but not 4 years later in 1987. None of the associations between maternal depression and mother reporting errors were significant. Among 8- to 12-year-olds in 1983, maternal depression was associated significantly not only with conduct problems ( = .17) and hyperactivity ( = .15) but also with mother rating errors of these behaviors ( = .13 and .17, respectively). Four years later in 1987 when this cohort was 12 to 16 years old, the only significant association was between maternal depression and conduct disorder ( = .25). Although evidence exists for associations between maternal depressed mood and mother rating errors, there also appears to be a substantive association between maternal depression and childhood behavior. 相似文献
