Do we think people with beards are more trustworthy?
is research analyses the effects of endorsers' beardedness (i.e., the state of being bearded) on their perceived credibility and consumers' purchase intention for various categories of products. According to Ohanian (1990), credibility is a construct with three sub-dimensions: attractiveness, the degree to which the source's physical appearance and/or its perceived personality is appealing; expertise, the extent to which the communicator is perceived as a source of valid assertions; and trustworthiness, the degree of confidence aroused in perceivers. Recent research has…

Do you change your voice when you talk to attractive people of the opposite sex?
th men and women deepen their voice when talking to someone they find attractive: We examined how individuals may change their voices when speaking to attractive versus unattractive individuals, and if it were possible for others to perceive these vocal changes. In addition, we examined if any concurrent physiological effects occurred when speaking with individuals who varied in physical attractiveness. We found that both sexes used a lower-pitched voice and showed a higher level of physiological arousal when speaking to…

What should you do after learning something that you need to remember?
's a rat study, but my guess is it's applicable to humans as well: Study Objectives:Sleep deprivation negatively affects memory consolidation, especially in the case of hippocampus-dependent memories. Studies in rodents have shown that 5 hours of sleep deprivation immediately following footshock exposure selectively impairs the formation of a contextual fear memory. In these studies, both acquisition and subsequent sleep deprivation were performed in the animals' main resting phase. However, in everyday life, subjects most often learn during their active…

Orgasms Can Induce A Seizure
s, they can: Reflex seizures can occur in response to a variety of stimuli, both sensory and emotional. Common triggers include light and music; however, in a growing number of case reports, the phenomenon of sexual activity triggering epileptic seizures is described. The majority of these case reports have been in women so far, and most have been found to localise to the right cerebral hemisphere on interictal electroencephalography (EEG). We report the case of a 34-year-old male with orgasm-induced…

How can you quickly and easily strengthen your ability to remember something?
en people are asked to perform actions, they remember those actions better than if they are asked to talk about the same actions. But when people talk, they often gesture with their hands, thus adding an action component to talking. The question we asked in this study was whether producing gesture along with speech makes the information encoded in that speech more memorable than it would have been without gesture. We found that gesturing during encoding led to better recall,…

These methods are most effective in reducing anxiety:
appraising your feelings is a better solution for reducing anxiety: It has been suggested that reappraisal strategies are more effective than suppression strategies for regulating emotions. Recently, proponents of the acceptance-based behavior therapy movement have further emphasized the importance of acceptance-based emotion regulation techniques. In order to directly compare these different emotion regulation strategies, 202 volunteers were asked to give an impromptu speech in front of a video camera. Participants were randomly assigned to one of three groups. The Reappraisal…

Does double checking make you trust your memory less?
mpulsive checking occurs in both physical and mental forms and is a common symptom of obsessive-compulsive disorder (OCD). Though there has been much recent attention devoted to research on physical checking, mental checking has been largely neglected. Previous research has reliably found that repeated physical checking reduces memory confidence, vividness and detail, while memory accuracy remains relatively unaffected. The current study examined memory accuracy and meta-memory in (n = 62) undergraduate students for both physical and mental checks after repeated physical or…
