Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants but sacrifice control over sound presentation and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining whether online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing. 相似文献

The article sets out to show how an holistic approach in matters of sexuality is always more helpful than one-sided approaches. On the issue of internet pornography, the authors suggest that the recent anti-masturbation online movement ‘no fapping’ is based on wrong conclusions from insufficient evidence. We suggest that a holistic approach is called for, with emphasis on the embodied human. Abstinence or what is understood by ‘Platonic love’ is not a solution, according to Plato himself. From a phenomenological perspective, we suggest owning up to our strange bodies and habitualising sexual activity. 相似文献

The relationship between sexual behavior and pain sensitivity was assessed in 27 heterosexual men and 20 heterosexual women. Sexual behavior measures included sexual motivation and ratings of subjective sexual arousal to and enjoyment of an auditory stimulus. Pain sensitivity measures were pain threshold and pain tolerance in a cold pressor task. Participants were tested after exposure to a neutral or a sexual audio stimulus. Exposure to the sexual stimulus increased pain sensitivity in women but not in men. However, sexual behavior measures were correlated with pain threshold for both men and women. Specifically, higher pain thresholds were associated with weaker sexual motivation, lower enjoyment potential for sexual interaction, and increased inhibition during intercourse. These results are consistent with findings in laboratory animals, suggesting that differences in sexual behavior may reflect differences in responsiveness to a variety of stimuli. 相似文献

How do people come up with humorous ideas? In creative cognition research, exposure to good examples sometimes causes fixation (people get “stuck” on the examples) but other times sparks inspiration (people's responses are more creative). The present research examined the effects of funny and unfunny examples on joke production. A sample of 175 adults read scenarios that they completed with funny responses. All participants were instructed to be funny, but before responding they read (a) funny responses as examples of good responses to emulate, (b) unfunny responses as examples of poor responses to avoid, or (c) no examples. The participants’ own responses were rated for funniness and for similarity to the example responses, and response times were recorded. Reading either funny or unfunny examples, compared to no examples, caused people to come up with funnier jokes. Similarity to the examples was low in all conditions, so fixation was relatively modest, but people who saw unfunny examples spent more time coming up with their responses. Taken together, the findings support the growing literature showing that examples are often inspiring rather than constraining, and they imply that good and bad examples spark creative thought via different paths. 相似文献

Individuals who perpetrate violence may likely perceive violence as appealing and infliction of violence to derive pleasure is termed as appetitive aggression. Individuals who were abducted as children into an armed group often experience a higher number of traumatic event types, that is traumatic load and are usually socialized in a violence-endorsing environment. This study aims to investigate the interaction between age at initial abduction with that of traumatic load, and their influence on appetitive aggression along with perpetration of violent acts by former members of an armed rebel group of both sexes. Semi-structured interviews were conducted among a target group of formerly abducted rebel-war survivors (including participants with and without combat experience) from Northern Uganda. Participants included 596 women and 570 men with N = 1,166 (Mage = 32.58, SDage = 9.76, range: 18–80 years). We conducted robust linear regression models to investigate the influence of age at initial abduction, traumatic load, combat experience, and biological sex on appetitive aggression as well as their perpetrated violent acts. Our study shows, appetitive aggression and the number of perpetrated violent acts were specifically increased in individuals who were abducted young, experienced several traumatic events in their lifetime, and with previous combat experience. For perpetrated violence men showed increased levels whereas for appetitive aggression the association was independent of biological sex. Therefore, early abducted individuals with a higher traumatic load, who have combat experience, need to be given special intervention to prevent any further violence. 相似文献

Even though economic globalization and foreign trade are major topics in the political discourse of most societies and negative attitudes toward international trade are prevalent, there is a lack of research investigating the ideological roots of protectionist preferences from a psychological perspective. In the present research, we examined the implications of right-wing authoritarianism (RWA) and social dominance orientation (SDO) for trade attitudes. Using data from two nationally representative samples from the United States (Study 1) and Germany (Study 2), we found that RWA predicted protectionist attitudes above and beyond economic self-interest. Furthermore, we found that the relationship between RWA and opposition to international trade was moderated by political involvement. The association of SDO with protectionist attitudes was inconsistent across the two studies and was not moderated by political involvement. Taken together, these results emphasize the importance of basic ideological orientations and the psychological dispositions they reflect in explaining public attitudes toward international trade. 相似文献

ABSTRACTUnderstanding individuals’ encounters with Customs and Border Protection (CBP), the largest law enforcement agency in the United States, is an important theoretical and policy-relevant issue. Travelers entering the U.S. through ports of entry may generalize their experiences with border officials to local law enforcement, and thus, negative experiences at ports of entry may reduce travelers’ willingness to cooperate with police and report victimization. Existing studies, however, have primarily examined unauthorized border crossings rather than travelers’ port of entry experiences. This study uses grounded theory and qualitative data to explore the perceptions and experiences of 191 young adults who discussed how individuals are treated when crossing the U.S.-Mexico border at land ports of entry. Findings show that participants reported perceptions and experiences of discrimination based on physical appearances, language differences, and nationality. Participants also described border officials engaging in routine law enforcement behaviors, including poor policing practices. 相似文献

Research on risk assessment in sentencing has focused heavily on the role of judges. Ignoring the role of other courtroom actors in the sentencing process, however, leaves unexamined the potentially significant effects on judicial decision making of arguments made by prosecutors and defense attorneys at sentencing hearings. Unduly focusing on judges also overlooks the vast majority of sentences arrived at through negotiated guilty pleas. We explored the extent to which considerations of risk are made among prosecutors and defense attorneys when advocating for given sentences in open court or during plea negotiations. We surveyed all prosecutors and defense attorneys in 14 judicial circuits in Virginia and found that most prosecutors and defense attorneys at least “sometimes” explicitly invoked actuarial risk estimates both at sentencing hearings and during plea negotiations. However, defense attorneys were much more likely than prosecutors to be averse to the use of risk assessment in either form of case disposition. 相似文献
