Reviewing and Summarizing Scientific Articles and Books
Question of the origin of play and playfulness has been one of concerns of Garry Chick, Professor at the Department of Recreation, Park and Tourism Management, Penn State University. From an evolutionary perspective, Professor Chick has developed a theory in which he explains adult play and playfulness. It is now known why children and offspring [...]... Read more »

Do you want to seem taller? Our study shows that your prestigious clothing affects perception of height, at least for the children. Height is a biological factor that can affect how others perceive and behave toward an individual. Clothing, as a non-biological factor, can affect these perceptions of height. In this study we investigated the [...]... Read more »

Thanks to the scientific investigations, now we know physical attractiveness would boost one’s social and sexual success. Attractive females would have more chances of being hired, and having attract/sustain men with more resources. It is hypothesized that female physical attractiveness is the signal for her fertility; i.e. men prefer attractive women because they are more [...]... Read more »

Waist-to-chest (WCR) and waist-to-shoulder (WSR) ratios are good predictors of male physical attractiveness and women have been shown to prefer higher waist-to-hip ratios (WHR) in men. This study addresses relationships between men’s body shapes and their feelings about appearance, weight and how others perceive them. The experimental results reported here demonstrate relationships between Iranian men’s shoulder-to-hip ratio (SHR) and WHR on self-reported body esteem and self-efficacy. Increases of SHR and WHR in these men were positively correlated with body esteem and increases of SHR with general self-efficacy. BMI was not correlated with either. These findings are interpreted in reference to men’s preferences for feminine ranges of WHR regardless of actual biological sex in relation to varying preferences that have been found cross-culturally and to self-perceived masculinity in relation to their mate and coalitional membership value.

How accurate is our perception of body forms? How do we identify the gender of a body? Do we have any cue?
In our recent paper, we showed that men and women accurately identify the genders on the basis of the waist to hip ratio. It is shown that as the waist to hip ratio increased, the frequency of “male” identifications increased and as this ratio decreased, the frequency of “female” identifications increased.

Walking down the street, while I was thinking, suddenly for a moment a beautiful face passed my sight. I turned my head to see that attractive face once again. But now I see that face was not as much attractive as I thought. I thought she was more beautiful!!!

Todd Tremlin, Minds and Gods: the cognitive foundations of religion. (Oxford University Press, Inc. USA, 2010), 256 pp., $27.12, ISBN: 978-0199739011
In human history, religions and their related issues have always been taken for granted and people have treated them as something sacred. Questioning of almost all religious beliefs hadn’t been allowed. Philosophical point of view seems not to be too much successful in identifying the main roots and origins of the religious thought and its related concepts like God.
Before new scientific progresses for explaining nature of religion, we always have had two main approaches to confront the phenomenon considered as holy creator, God. Some had assumed god as an omnipotent supernatural being, the creator that its existence is beyond and independent of human existence or behaving god and religious beliefs as man-made tools to exploit and abuse people, emotionally, politically and economically (p. 198).

Like all species, we humans also have evolved and armed with proper evolutionary tools – teeth for eating. There has been a consensus about evolution of our craniodental morphology and our preferred diets. But yesterday, a review article was published in Science investigating recent studies of early hominis diets. As review shows, using archeological and morphological methods, it was supposed that “hominin craniodental functional morphology evolved for increasing consumption of hard, brittle foods as savannas spread”. But using new techniques of Microwear and stable carbon isotope, now this assumption is incorrect, or at least too simplistic. Dental Microwear is the association between parallel striations and pits on teeth with pattern and food fracture properties. The review concludes that consumption of tropical grasses and sedges and hard-objects like seeds and nuts date to “millions of years after the appearance of the earliest probable hominins, and there are no consistent trends in diet ......

Probably many people are not more familiar with the Amazon than just knowing its name. How much do you know about the primates of these forests? Do you want to take a tour of the region? Are you interested in learning more about new world monkeys? If so, this book is for you.

Where do you go when you’re tired of modern society? Do you like to go on picnic and spend your time in nature? It seems natural environment has fundamental effects on our feelings. This paper showed that different environments elicit different affective responses and one might feel happier when is in direct contact with natural environment. This study suggests that this feeling might be due to our evolutionary past in Savannahs. Study presents that “some environments (e.g., mountains) may be associated with particular experiential states (e.g., indicating Eudemonia), and others (e.g., parks) seem to elicit other positive experiential states (e.g., fun and relaxation)”.
So it seems that spending time in nature might be vital for our psychological well-being. Let’s enjoy our animal inside in contact with natural environments!

A new study that is appeared in journal of Evolutionary Psychology, investigated effect of distance of partner and closeness of the rival person on jealousy. Study showed that spatial distance affects the intensity of jealousy. An amazing finding is that although men felt comfortable near their partner and far from the rival person, women still felt a bit jealous while they were with their men and far from the rival women.
In short, this study showed that “the jealousy mechanism responds with mild negative feelings at most as long as the partner is close to the jealous person” and also showed that men report stronger negative feelings than women when suspecting sexual infidelity, while women report stronger negative feelings than men when suspecting emotional infidelity.
