However, its impact on improving assisted reproductive technologies (ARTs) outcomes remains contentious. This study seeks to compare reproductive outcomes between infertile men who underwent varicocelectomy and those who did not prior to ARTs. In addition, it evaluates the influence of types of fertili…
Extrafoveal processing of happy face relies on visual awareness in hearing-impaired adults
Fearful expressions facilitate perceptual dominance of low spatial frequency information in visual awareness
The human brain optimises cognitive resource allocation to enhance the processing speed and efficiency of vital information for better survival and adaptation in response to threat signals. Previous studies found that fearful expressions, as visual cues signalling threats, can not only have advantages in entering and remaining in awareness, but also enhance subsequent perceptual processing of low-spatial-frequency (LSF) information. However, it r…

Being observed magnifies action
We test the hypothesis that people, when observed, perceive their actions as more substantial because they add the audience's perspective to their own perspective. We find that participants who were observed while eating (Study 1) or learned they were observed after eating (Study 2) recalled eating a larger portion than unobserved participants. The presence of others magnified both desirable and undesirable actions. Thus, observed (vs. unobserved…

How the perceived cost of prosocial action inspires observers to contribute
Conventional wisdom suggests that people are less likely to help when doing so involves a high cost. However, through five experiments, this work demonstrates that when a donor's prosocial action is perceived as costlier, observers are more likely to follow the donor and engage in the same prosocial behaviour (Study 1a, N = 154; Study 1b, N = 127). The effect cannot be attributed to observers’ original preferences for costly prosocial action itse…

The Role of Exemplification in Shaping Third-Person Perceptions and Support for Restrictions on Video Games
The origins of third-person perceptions remain uncertain, with most research focusing on psychological mechanisms. We investigate whether media content might also play a role, using a 2 × 2 experiment presenting a single story describing video games as harmful or harmless and using either research and statistics or a specific anecdotal exemplar to illustrate this claim. Results show perceived effects on others are influenced by the use of an exem…
The Effects of “Friend” Characteristics on Evaluations of an Activist Group in a Social Networking Context
Research suggests that individuals use cues about the popularity of a cause or group to make judgments. This bandwagon phenomenon has found particular support in online contexts. However, perceptions regarding the group may also depend on the identity of those supporters. We employed a 2 × 2 × 2 experiment to test the effect of number of affiliates and affiliate race and age on feelings toward the group, its page, and intended support. Results su…

User Experience of On-Screen Interaction Techniques
From scrolling and clicking to dragging, flipping, sliding, hovering, and zooming, the wide array of interaction techniques has vastly expanded the range of user actions on an interface. Each of these interaction techniques affords a distinct action. But do these techniques differ in their ability to engage users and contribute to their user experience? Furthermore, do they affect how users view the content and how much they learn from it? We add…
Coherence between health policy and human resource strategy
The failure to meet health goals such as the Millennium Development Goals (MDG) is partly due to the lack of appropriate resources for the effective implementation of health policies. The lack of coherence between the health policies and human resource (HR) strategy is one of the major causes. This article explores the relationship and the degree of coherence between health policy--in this case maternal health policy--processes and HR strategy in…
SNP-SNP Interaction between TLR4 and MyD88 in Susceptibility to Coronary Artery Disease in the Chinese Han Population
The toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-dependent signaling pathway plays a role in the initiation and progression of coronary artery disease (CAD). We investigated SNP-SNP interactions between the TLR4 and MyD88 genes in CAD susceptibility and assessed whether the effects of such interactions were modified by confounding risk factors (hyperglycemia, hyperlipidemia and Helicobacter pylori (H. pylori) infection). …
