Investigations of multiple-object tracking aim to further our understanding of how people perform common activities such as driving in traffic. However, tracking tasks in the laboratory have overlooked a crucial component of much real-world object tracking: self-motion. We investigated the hypothesis that keeping track of one’s own movement impairs the ability to keep track of other moving objects. Participants attempted to track multiple targets while either moving around the tracking area or remaining in a fixed location. Participants’ tracking performance was impaired when they moved to a new location during tracking, even when they were passively moved and when they did not see a shift in viewpoint. Self-motion impaired multiple-object tracking in both an immersive virtual environment and a real-world analog, but did not interfere with a difficult non-spatial tracking task. These results suggest that people use a common mechanism to track changes both to the location of moving objects around them and to keep track of their own location. 相似文献

In a situation indicating possible pseudo-participation, we examined whether outcome favorability affects perceived procedural fairness and resentment as a result of self-serving attributions for outcomes. Laboratory participants received a production target that was either substantially above (i.e., unfavorable outcome) or substantially below (i.e., favorable outcome) a target they had voiced to a supervisor. As hypothesized, outcome favorability was related to procedural fairness (positively) and resentment (negatively) among participants who lacked persuasive evidence of pseudo-participation. In support of the idea that these effects were a result of self-serving attributions, rather than instrumental concerns, they did not emerge among participants who had persuasive evidence of pseudo-participation. 相似文献

Young adults with (or without) a history of medical or physical disorders (MPDs) were exposed to repeated laboratory stress. The effects of MPD status on habituation (as measured by changing levels of cortisol) were found to be moderated by the extent to which respondents reported “attachment feelings” in their relationships (as measured by the Social Provisions Scale). Students in the MPD group who reported attachment feelings showed (a) cortisol increases during their first exposure to a laboratory stressor; and (b) cortisol decreases during a second exposure to the same stressor 1 week later. No equivalent benefit was found for students who lacked this medical history. Findings suggest the extent to which medical adversity—under the right interpersonal circumstances—promotes resilience. 相似文献

In a recognition memory experiment, Mickes, Wixted, and Wais (2007) reported that distributional statistics computed from
ratings made using a 20-point confidence scale (which showed that the standard deviation of the ratings made to lures was
approximately 0.80 times that of the targets) essentially matched the distributional statistics estimated indirectly by fitting
a Gaussian signal-detection model to the receiver-operating characteristic (ROC). We argued that the parallel results serve
to increase confidence in the Gaussian unequal-variance model of recognition memory. Rouder, Pratte, and Morey (2010) argue
that the results are instead uninformative. In their view, parametric models of latent memory strength are not empirically
distinguishable. As such, they argue, our conclusions are arbitrary, and parametric ROC analysis should be abandoned. In an
attempt to demonstrate the inherent untestability of parametric models, they describe a non-Gaussian equal-variance model
that purportedly accounts for our findings just as well as the Gaussian unequal-variance model does. However, we show that
their new model—despite being contrived after the fact and in full view of the to-be-explained data—does not account for the
results as well as the unequal-variance Gaussian model does. This outcome manifestly demonstrates that parametric models are,
in fact, testable. Moreover, the results differentially favor the Gaussian account over the probit model and over several
other reasonable distributional forms (such as the Weibull and the lognormal). 相似文献

The aim of the present study was to assess adolescent renal transplant recipients’ perceived adversity (PA) for various aspects
of living with a transplant, including its association with coping and medication non-adherence, from a theoretical perspective.
Thirty-three adolescent renal transplant recipients were interviewed using structured questionnaires and medical record reviews.
Health care provider ratings of adversity were also collected. Participants reported moderate levels of PA, with those who
received a transplant at an older age reporting more adversity on several domains and girls reporting more adversity for missing
school. Ratings of adversity for specific aspects of living with a transplant differed depending on age and medical factors
and were related to specific coping strategies and measures of non-adherence. Consistent with the Self-Regulation Model, perceived
consequences (represented as PA) appears to be related to coping and illness outcomes. Assessing PA and teaching appropriate
coping strategies may yield better medical outcomes among this at-risk population. 相似文献

Adult colour preference has been summarized quantitatively in terms of weights on the two fundamental neural processes that underlie early colour encoding: the S−(L+M) (‘blue–yellow’) and L−M (‘red–green’) cone‐opponent contrast channels ( Ling, Hurlbert & Robinson, 2006 ; Hurlbert & Ling, 2007 ). Here, we investigate whether colour preference in 4–5‐month‐olds may be analysed in the same way. We recorded infants’ eye‐movements in response to pairwise presentations of eight colour stimuli varying only in hue. Infants looked longest at reddish and shortest at greenish hues. Analyses revealed that the L−M and S−(L+M) contrast between stimulus colour and background explained around half of the variation in infant preference across the hue spectrum. Unlike adult colour preference patterns, there was no evidence for sex differences in the weights on either of the cone‐opponent contrast components. The findings provide a quantitative model of infant colour preference that summarizes variation in infant preference across hues. 相似文献

We examined the psychosocial maladjustment of 32 children with an incarcerated parent from the child’s perspective as well
as from the perspective of their caregiver. We focused on the relation between the incarcerated parent’s report of children’s
exposure to parental criminal activity, arrest, and sentencing and caregivers’ and children’s self-reports of maladjustment.
Results indicate that witnessing these events is associated with more behavior problems according to caregivers’ and children’s
self-reports. Moreover, incarcerated parents’ reports of children’s exposure to these events predicted caregivers’ and children’s
reports of maladjustment over a 6 month period. Our results also suggest that children with incarcerated mothers, in comparison
to children with incarcerated fathers, are exposed to more of these events and may be experiencing greater maladjustment.
Implications of these findings are discussed within a proactive context and the use of procedures that take children’s reactions
to witnessing parental arrest and sentencing into consideration. 相似文献

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation
require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity
of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and
age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving
ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages
in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in
their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had
a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when
given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found
no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability
for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural
innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed
by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological
success. 相似文献

This project examined the ethical issues faced by academics and professionals in the Humanities. We conducted focus groups
to gather information about the ethical concerns in these fields and used the qualitative data arising from the discussions
to create a taxonomy that represents the structure of ethical issues in the Humanities. A key implication of our findings
is that while the focus of ethics research and interventions has been primarily on the sciences and engineering, academics
and professionals in other fields also encounter some unique critical ethical dilemmas that require further research and methods
of intervention. 相似文献
