Answers to sensitive questions are prone to social desirability bias. If not properly addressed, the validity of the research can be suspect. This article presents multigroup item randomized response theory (MIRRT) to measure self-reported sensitive topics across cultures. The method was specifically developed to reduce social desirability bias by making an a priori change in the design of the survey. The change involves the use of a randomization device (e.g., a die) that preserves participants' privacy at the item level. In cases where multiple items measure a higher level theoretical construct, the researcher could still make inferences at the individual level. The method can correct for under- and overreporting, even if both occur in a sample of individuals or across nations. We present and illustrate MIRRT in a nontechnical manner, provide WinBugs software code so that researchers can directly implement it, and present 2 cross-national studies in which it was applied. The first study compared nonstudent samples from 2 countries (total n = 927) on permissive sexual attitudes and risky sexual behavior and related these to individual-level characteristics such as the Big Five personality traits. The second study compared nonstudent samples from 17 countries (total n = 6,195) on risky sexual behavior and related these to individual-level characteristics, such as gender and age, and to country-level characteristics, such as sex ratio.

In the midst of growing reservations about Muslims in America, this study seeks to explore the factors accounting for Islamophobia
by utilizing nationally representative data. The findings suggest that religious affiliations have differential effects on
the degree to which one respects Islam, with Christians more likely to have low regard for Islam. The image of a God who punishes
his followers for their sins has a positive association with the odds of Islam being least respected among all religions.
While higher frequency of contact with Muslims predicts an overall improved opinion for Islam, evangelical and black Protestants
present the opposite picture. Their increased exposure to Muslims leads to lower respect for Islam. I discuss the implications
of these findings for theories of intergroup contact and subcultural identity. 相似文献

Several molecules were recently found to be important for the memory retrieval process in the hippocampus; however, the mechanisms underlying the memory retrieval remain poorly understood. GSK-3β has been implicated in the control of synaptic plasticity and memory formation. Here, we investigated the relationship between hippocampal GSK-3β activity and memory retrieval using behavioral and Western blotting methods. We found that GSK-3β was activated in the hippocampus after a retention session in the passive avoidance task. An intrahippocampal injection of the GSK-3β inhibitor, SB 216763, before the retention session blocked memory retrieval (but not reconsolidation) without affecting locomotor activity. These results suggest that GSK-3β activation would be essential for memory retrieval in the hippocampus. 相似文献

Length effects in the lexical decision latencies of children might indicate that children rely on sublexical processing and essentially approach the task as a naming task. We examined this possibility by means of the effects of neighbourhood size and articulatory suppression on lexical decision performance. Sixty-six beginning and 62 advanced readers performed a lexical decision task in a standard, articulatory suppression, or tapping condition. We found length effects on words and nonwords in the children's lexical decisions. However, the effects of neighbourhood size were similar to those reported for adult lexical decisions, rather than the effects previously found in children's naming. In addition, no effect was found of articulatory suppression. Both findings suggest that, despite clear length effects, children do not adopt a naming task approach but, like adults, base lexical decisions mainly on a lexical search. These results pose a challenge for several computational models of reading. 相似文献

Abstract The use of online video games as an advertising channel has become an integrated part of branding for many marketers in an increasingly fractured media environment. The primary question motivating this research is whether the use of an animated spokes-character embedded in online game affects the persuasiveness of advertising. Specifically, this study looks at how product types moderate the magnitude of such effects. The results show a significant interaction effect between character presence and product type on both brand attitude and purchase intention. The effects of an animated spokes-character on brand evaluation and purchase intention were more pronounced for utilitarian products than for hedonic products. 相似文献

Lewis claims that Martin’s cases indeed refute the simple conditional analysis of dispositions and proposes the reformed conditional
analysis that is purported to overcome them. In this paper I will first argue that Lewis’s defense of the reformed analysis
can be understood to invoke the concepts of disposition-specific stimulus and manifestation. I will go on to argue that advocates
of the simple analysis, just like Lewis, can also defend their analysis from alleged counterexamples including Martin’s cases
by invoking the concepts of disposition-specific stimulus and manifestation. This means that Lewis’s own necessary defense
of the reformed analysis invalidates his motivation of it. Finally, I will argue that we have a good reason to favor the simple
analysis over Lewis’s analysis. 相似文献

The patient we call Danny was a mildly mentally retarded male in his mid-thirties who adamantly refused kidney dialysis when it was offered as the only therapeutic option for his progressive kidney failure. It was uncertain how fully Danny understood the implications of his refusal. To complicate the case still further, several “advocates” emerged to speak on Danny's behalf — each with a somewhat different interpretation of the situation and different sets of value presuppositions and ethical principles to apply to the choice. We chronicle the development of this situation through a series of scenes; and in each scene we also attempt to clarify the ethical and medico-legal issues involved at that point. Danny was finally permitted to make this decision for himself — though more by default than by an agreement by all parties to honor his autonomy. Our hope is that this presentation will lead to further discussion and clarification of these important issues. 相似文献

Waning of panic sensations during prolonged hyperventilation 总被引:2,自引:0,他引:2

Recent theories about panic emphasize that a hyperventilatory positive feedback loop is involved in panic: catastrophic misinterpretation of bodily sensations may trigger anxiety, anxiety may stimulate hyperventilation, hyperventilation may promote the salience of feared sensations etc. Such models leave unexplained how and when panics come to an end. It was hypothesised that panic with hyperventilation may end because pronounced hyperventilation becomes, in the course of time, less powerful in generating perceivable bodily sensations. Twenty healthy subjects hyperventilated forcefully and experienced clear panic symptoms as defined by DSM IIIR. When pCO2 was kept 55% below base line for 90 min, panic symptoms waned. The mean intensity of the symptoms declined as did the number of symptoms occurring. No panic symptoms were observed in the control group (n = 20) who ventilated normally. In so far as hyperventilation is involved in the positive feedback loops that characterize panic, panic attacks may be time-limited because sensations induced by hyperventilation become less salient even if massive hyperventilation continues. As to the explanation of the reported phenomenon, it is suggested that, apart from habituation, local physiological changes due to prolonged hyperventilation may produce a decrease in interoceptive input. 相似文献

In search of the point of no return: the control of response processes 总被引:12,自引:0,他引:12

Control processes underlying response inhibition were examined. Six Ss performed a visual choice reaction task and were occasionally presented with a tone that told them to withhold the response. Reaction time results were in agreement with a model that assumes a race between response activation and response inhibition processes. Event-related brain potentials, electromyogram, and continuous response measures showed that responses could be interrupted at any time. Evidence was obtained for two inhibitory mechanisms: inhibition of central activation processes and inhibition of transmission of motor commands from central to peripheral structures. Results have implications for the distinction between controlled and ballistic processes. 相似文献

Summary This paper discusses the concept of stratification, in the sense of levels of analysis and levels of control, in relation to human perception and performance. It is contended that functional analysis is the proper level of analysis for the domain of perception and action. This is illustrated by means of models of cognitive energetics and motor control. The functional level of analysis can be situated in between the level of symbolic representations and the level of neurophysiological mechanisms. It is also argued that the concept of levels of control provides a way of integrating or relating ecological and information-processing approaches to psychology, in the sense that ecological psychology is concerned with lower and more peripheral levels of control (coordinative structures). Finally, some remarks are made on the relation between cognition and perception and action, drawing on Piaget, and it is proposed that the concept of schema is more appropriate for the domain of perception and action than is the notion of symbolic representations. 相似文献
