When two target items (T1 and T2) are presented in rapid succession among fillers, processing T2 is often impaired. This phenomenon is known as the attentional blink (AB). Within the visual modality, this second-target deficit generally occurs only if T2 is masked by a trailing item. The current study was designed to examine whether masking of T2 also plays a critical role in the auditory AB. Results showed a reliable AB effect even when the item following T2 was replaced by silence. However, the AB deficit was abolished when T2 was the last presented stimulus. Our results suggest that, as in vision, T2 masking is necessary for the AB to take place in audition, but that masking is effective even when delayed, providing evidence that the phenomenon shares some functional mechanisms across sensory modalities. 相似文献

We compared men who have sex with other men on the Internet with the remainder of the sample of men who reported only sex with women on the Internet, in a sample of 1,846 Swedish men recruited from a major Swedish portal. We report on the self-identified heterosexual men in the sample who reported engaging in cybersex in the past year, and for whom there was complete data on sexual identity and the gender of cybersexual partners. Of the 244 cases with full data, 76% were heterosexual in both identity and behavior, 16% were gay or bisexual in identity and reported both male and female cybersexual contacts on the Internet, and 8% indicated their sexual preference was heterosexual but also reported at least one male sexual partner on the Internet. Thus, 11% of self-identified heterosexual men had sex with other men online. Comparing the two groups, the men who had sex with men (MSM) who did not identify (MSM-NI) spent significantly more time per week online, although a similar amount of time on sexual pursuits, as the heterosexual men. The MSM-NI were significantly more likely to agree that their online sexuality had affected their sexuality in a positive way, to have bought sex from prostitutes, to agree that they do things online that they would not do offline, have cybersex more often, use a web-camera and microphone more often, flirt and visit contact sites more often, and agree more often that sexual thoughts and behaviors are causing problems, desire to have sex creates problems, and sometimes fail to meet commitments due to their sexual behavior. These data taken together suggest that MSM-NI online are not uncommon and are characterized by the extent of their cybersexual involvement that sometimes extends to other men. Such men may rationalize this cybersex with other men as not, or minimally, sexual in much the same way as Humphreys characterized MSMs in public restrooms. 相似文献

In order to examine the fit between realism and science, one needs to address two issues: the unit of science question (realism
about which parts of science?) and the contents of realism question (which realism about science?). Answering these questions
is a matter of conceptual and empirical inquiry by way local case studies. Instead of the more ordinary abstract and global
scientific realism, what we get is a doubly local scientific realism based on a bottom-up strategy. Representative formulations
of the former kind are in terms of the truth and reality of the posits of current science, in terms of warranted belief, in
terms of mind-independent unobservable entities. Using illustrations mainly from the social sciences, doubly local scientific
realism denies the global applicability of such formulations and seeks to make adjustments in their elements in response to
information about local units of science: It is sufficient for a realist to give the existence of an entity (and the truth
of a theory) a chance, while in some areas we may be in s position to make justified claims about actual existence (and truth).
Logical inquiry-independent existence is sufficient for the social and human sciences, while mind-independence will be fine
for many other domains. It should not be insisted that the theoretical posits of realist science be strict unobservables in
all areas: most theoretical posits of the social sciences are idealized commonsensibles, such as elements in folk psychology.
Unsurprisingly, this sort of local strategy will create space for realism that is able to accommodate larger areas of science
without sacrificing traditional realist intuitions. 相似文献

A fundamental question for evaluation research is whether cues can impact evaluative responses directly or only in combination with contextual information. Focusing on the experience of processing fluency, the current work tested whether manipulating this cue’s motivational context would moderate its evaluative impact. Because fluently processed stimuli can be assumed to communicate safety, owing to implicit signals of either familiarity (through processes monitoring perception-memory coordination), we reasoned that motivation to avoid negative events should heighten preferences for fluently processed stimuli. Following a motivation manipulation, prevention-focused, but not promotion-focused, participants preferred stimuli that they were able to process quickly (Experiment 2) and that were preceded by concordant primes (Experiment 1). These findings suggest that the value of fluent processing reflects its relation to contextual features, such as one’s current motivational state. 相似文献

T his paper examines the impact of dispositional Need for Cognitive Closure (NFC) on different political attitudes and on the “person blame” and the “system blame” dimensions. Two hundred and thirty‐four psychology students completed a questionnaire containing the Italian version of the Need for Closure scale, a measure of political and ideological attitudes, a measure of the person‐system blame dimensions, and a measure of past voting. Results showed that high NFC individuals (vs. low NFCs) reported having voted for a right‐wing party and holding more conservative attitudes. High NFCs (vs. low NFCs) turned out to have stronger anti‐immigrant attitudes, to be more nationalistic, to prefer an autocratic leadership and a centralized form of political power. High NFCs also value religiosity more highly than low NFCs. High NFCs (vs. low NFCs) scored lower on pluralism and multiculturalism. Furthermore, high NFCs (vs. low NFCs) revealed a tendency to blame individuals for social problems, but no significant difference was found with regard to the system blame dimension. Results are discussed in the light of the motivated social cognition approach (Jost, Glaser, Kruglanski, & Sulloway, 2003). 相似文献

The psychometric properties of the 18-item circadian type inventory (CTI) were examined in a non-shiftwork sample. Inter-item correlations for each scale were low to moderate. Confirmatory factor analysis (CFA) via structural equation modelling did not support the posited structure of the CTI. Principal components analysis and reliability analyses suggested the CTI is better represented by 11-items. The revised five item FR scale accounted for 27% of the variance, had stronger factor loadings and increased Cronbach alpha. The psychometric properties of the six item LV scale were marginally improved and explained 21% of the variance. The two-factor 11-item model was supported by CFA. Compared to the 18-item model, the 11-item model showed a marked improvement on several incremental fit indices and achieved a more parsimonious model fit. There was some indication of gender differences but a multi-group CFA indicated model parsimony was best for the invariant model. Gender difference needs to be further examined in large samples using a similar gender balance. It is concluded that the 11-item CTI is psychometrically superior to the original. However, its predictive efficacy needs to be examined in longitudinal studies. 相似文献

Gender differences in play behavior are well documented. However, little work has examined the issue of variability of gender-typed behaviors within individuals or within genders. We investigated whether children's gender-typed toy play behavior is (a) variable across time within individuals, and (b) variable in response to exposure to counterstereotypic models. Extensive observations (N=203) were made of 8 highly gender-typed preschool children over 4 months. Variability was assessed by examining changes in the percentage of masculine and feminine toy play across successive days in which (a) gender neutral stories were read (within-individual variability) and (b) gender counterstereotypic stories were introduced (environmental variability). Variability of gender-typed play within individuals and in response to environmental stimuli was found among girls, but not among boys. 相似文献

We compare astronomers' removal of Pluto from the listing of planets and psychiatrists' removal of homosexuality from the
listing of mental disorders. Although the political maneuverings that emerged in both controversies are less than scientifically
ideal, we argue that competition for "scientific authority" among competing groups is a normal part of scientific progress.
In both cases, a complicated relationship between abstract constructs and evidence made the classification problem thorny. 相似文献
