We summarize five studies of our large-scale research program, in which we examined aspects of contour-based object identification
and segmentation, and we report on the stimuli we used, the norms and data we collected, and the software tools we developed.
The stimuli were outlines derived from the standard set of line drawings of everyday objects by Snodgrass and Vanderwart (1980).
We used contour curvature as a major variable in all the studies. The total number of 1,500 participants produced very solid,
normative identification rates of silhouettes and contours, straight-line versions, and fragmented versions, and quite reliable
benchmark data about saliency of points and object segmentation into parts. We also developed several software tools to generate
stimuli and to analyze the data in nonstandard ways. Our stimuli, norms and data, and software tools have great potential
for further exploration of factors influencing contour-based object identification, and are also useful for researchers in
many different disciplines (including computer vision) on a wide variety of research topics (e.g., priming, agnosia, perceptual
organization, and picture naming). The full set of norms, data, and stimuli may be downloaded fromwww.psychonomic.org/archive/. 相似文献

The ability of parties to not only reflect, but actually shape, citizens' preferences on policy issues has been long debated, as it corresponds to a fundamental prediction of classic party identification theory. While most research draws on data from the United States or studies of low-salience issues, we exploit the unique opportunity presented by the 2013 Italian election, with the four major parties of a clear multiparty setting holding distinct positions on crucial issues of the campaign. Based on an experimental design, we test the impact of party cues on citizens' preferences on high-salience issues. The results are surprising: Despite a party system in flux (with relevant new parties) and a weakening of traditional party identities, we find large, significant partisan-cueing effects in all the three experimental issues, and for voters of all the major Italian parties—both old and new, governmental and opposition, ideologically clear or ambiguous. 相似文献

Understanding how parents influence their child’s medical procedures can inform future work to reduce pediatric procedural distress and improve recovery outcomes. Following a pediatric injury or illness diagnosis, the associated medical procedures can be potentially traumatic events that are often painful and distressing and can lead to the child experiencing long-term physical and psychological problems. Children under 6 years old are particularly at risk of illness or injury, yet their pain-related distress during medical procedures is often difficult to manage because of their young developmental level. Parents can also experience ongoing psychological distress following a child’s injury or illness diagnosis. The parent and parenting behavior is one of many risk factors for increased pediatric procedural distress. The impact of parents on pediatric procedural distress is an important yet not well-understood phenomenon. There is some evidence to indicate parents influence their child through their own psychological distress and through parenting behavior. This paper has three purposes: (1) review current empirical research on parent-related risk factors for distressing pediatric medical procedures, and longer-term recovery outcomes; (2) consider and develop existing theories to present a new model for understanding the parent–child distress relationship during medical procedures; and (3) review and make recommendations regarding current assessment tools and developing parenting behavior interventions for reducing pediatric procedural distress. 相似文献

Expressing (vs. withholding) forgiveness is often promoted as a beneficial response for victims. In the present research, we argue that withholding (vs. expressing) forgiveness can also be beneficial to victims by stimulating subsequent transgressor compliance – a response that is valuable in restoring the victim’s needs for control. Based on deterrence theory, we argue that a victim’s withheld (vs. expressed) forgiveness promotes transgressor compliance when the victim has low power, relative to the transgressor. This is because withheld (vs. expressed) forgiveness from a low-power victim elicits transgressor fear. On the other hand, because people are fearful of high-power actors, high-power victims can expect high levels of compliance from a transgressor, regardless of whether they express forgiveness or not. A critical incidents survey (Study 1) and an autobiographic recall study (Study 2) among employees, as well as a laboratory experiment among business students (Study 3), support these predictions. These studies are among the first to reveal that withholding forgiveness can be beneficial for low-power victims in a hierarchical context – ironically, a context in which offering forgiveness is often expected. 相似文献
