We aren’t born afraid of spiders and snakes

People aren’t born afraid of spiders and snakes, but can learn these fears very quickly during infancy, says a new research.

Scientists have studied how infants and toddlers react to scary objects. In one set of experiments, they showed infants as young as 7 months old two videos side by side-one of a snake and one of something non-threatening, such as an elephant.

At the same time, the researchers played either a fearful voice or a happy voice. The babies spent more time looking at the snake videos when listening to the fearful voices, but showed no signs of fear themselves.

“What we’re suggesting is that we have these biases to detect things like snakes and spiders really quickly, and to associate them with things that are yucky or bad, like a fearful voice,” said Vanessa LoBue of Rutgers University.
In another study, 3-year-olds were shown a screen of nine photographs and told to pick out some target item. They identified snakes more quickly than flowers and more quickly than other animals that look similar to snakes, such as frogs and caterpillars.

Children who were afraid of snakes were just as fast at picking them out than children who hadn’t developed that fear.

“The original research by Ohman and Mineka with monkeys and adults suggested two important things that make snakes and spiders different. One is that we detect them quickly. The other is that we learn to be afraid of them really quickly,” LoBue said.

Her research on infants and young children suggests that this is true early in life, too-but not innate, since small children aren’t necessarily afraid of snakes and spiders.

The study is published in Current Directions in Psychological Science, a journal of the Association for Psychological Science.

Kerajaan Jeumpa, Kerajaan Islam Pertama Nusantara

Teori tentang kerajaan Islam pertama di Nusantara sampai saat ini masih banyak diperdebatkan oleh para peneliti, baik cendekiawan Muslim maupun non Muslim. Umumnya perbedaan pendapat tentang teori ini didasarkan pada teori awal mula masuknya Islam ke Nusantara. Mengenai teori Islamisasi di Nusantara, para ahli sejarah terbagi menjadi 3 kelompok besar, yaitu pendukung (i) Teori Gujarat (ii) Teori Parsia dan (iii) Teori Mekah (Arab). Bukan maksud tulisan ini untuk membahas teori-teori tersebut secara mendetil, namun dari penelitian yang penulis lakukan, maka dapat disimpulkan bahwa Teori Mekkah (Arab) lebih mendekati kebenaran dengan fakta-fakta yang dikemukakan. Teori Mekkah (Arab) hakikatnya adalah koreksi terhadap teori Gujarat dan bantahan terhadap teori Persia. Di antara para ahli yang menganut teori ini adalah T.W. Arnold, Crawfurd, Keijzer, Niemann, De Holander, SMN. Al-Attas, A. Hasymi, dan Hamka. i Arnold menyatakan para pedagang Arab menyebarkan Islam ketika mereka mendo...

MyWare: Personalized Service or Invasion of Privacy?

There's a fine line between what is considered a knowledge database and an invasion of privacy, and that line is likely to be determined by marketing. This week we wrote an article about Please Rob Me - a service that identifies Foursquare and Gowalla check-ins on Twitter and lets others know that a person is not home. While location-based services are often touted for their social and recommendation-based benefits, the realization that they can be used negatively have many questioning the responsibility of those groups that collect the data. In mid January Facebook founder Mark Zuckerberg stated that the age of privacy had come to an end and we responded that evolving preferences were not a valid justification of the elimination of privacy preferences . Nevertheless, between cookie tracking and browser identifiers like those shown in the EFF's Panopticlick and the fact that it only takes your zip code, gender and birthdate to identify you, it's hard to ensure to...

Johnny Depp Meninggal Hanya Hoax

Aktor Johnny Depp jadi trending topic di situs jejaring sosial, Twitter. Penyebabnya karena Depp disebut-sebut telah meninggal dunia. Benarkah? Ternyata tidak. Bahan perbincangan para pengguna Twitter didasarkan dari screenshot situs berita CNN yang disebutkan dimuat tahun 2004 silam. Screenshot berita itu pun sebenarnya telah dinyatakan sebagai kesalahan teknis oleh CNN. CNN ketika itu mengaku telah lalai dalam memuat nama korban kecelakaan lalu lintas menjadi Johnny Depp. Padahal yang menjadi korban saat itu bukan aktor top Johnny Depp. Sejumlah situs berita asing yang selama ini dikenal memiliki keakuratan dan kecepatan berita pun tidak memuat mengenai meninggalnya Depp. Situs BBC, Reuters, Contact Music, Female First, Daily Mail, The Sun hingga CNN tidak melansir berita meninggalnya pemain film 'Donnie Brasco' tersebut pada Minggu (24/1/2010).
