Does 000,000 Matter? Psychological Effects of Turkish Monetary Reform
(Elsevier Science Bv, 2007) Amado, Sonia; Tekozel, Mert; Topsever, Yurdal; Ranyard, Rob; Del Missier, Fabio; Bonini, Nicolao
Turkish monetary reform, which took effect in January 2005, introduced the New Turkish Lira (NTL) by deleting six zeros from the former currency, the Turkish Lira (TL). Two experiments investigated how the introduction of the NTL might affect price estimation. In the first, conducted in December 2004, 202 students were first presented with high or low anchor values and then estimated the average price of a new Turkish mid-sized car in different currencies (TL, NTL and Euro). Although anchoring bias was not significantly different across familiar (TL) and unfamiliar currencies (NTL and Euro), price estimates in Euro and NTL were significantly higher than those in TL. In the second experiment, carried out 6 months later, 212 adult consumers estimated the prices of 13 items in one of three currencies. For five items prices estimated in Euros were significantly higher than those expressed in either TL or NTL. However, there were no significant differences between TL and NTL, suggesting that Turkish consumers had quickly adapted. Such ease of adaptation is consistent with a rescaling hypothesis: when one or more zeros are dropped from a currency, consumers rescale all prices relatively quickly rather than relearn them selectively through gradual exposure.

Hemispheric Asymmetry in Expression and Perception of Happiness
(Turkish Psychologists Assoc, 2012) Gulbetekin, Evrim; Iyilikci, Osman; Amado, Sonia; Cetinkaya, Hakan; Dural, Seda
Hemispheric asymmetries in happiness expression -which has an important role in interpersonal communication and its perception- have been studied using different techniques. However, it is not clear whether the source of the asymmetry is the poser or the observer. In Experiment I, we investigated on which hemiface (right/left) the expression of happiness was better identified. Subjects evaluated right-sided happy chimeric faces as more expressive. In Experiment II, we examined whether the source of the bias was the observer's hemispheric asymmetry or the poser's facial asymmetry. Stimuli were briefly presented unilaterally, either in the left visual field(LVF)/right hemisphere(RL) or in the right visual field(RVF)/left hemisphere(LH). Faces were recognized faster in LVF condition, but they were evaluated as more expressive in RVF condition. Right-sided happy faces were found to be more expressive in RVF condition. Results indicated LH superiority in the recognition of happy expression and a RH superiority in the duration of facial processing. Additionally findings pointed out a sex difference in subjects' evaluation time and evaluation scores. Men evaluated the stimuli faster in the RH condition than they did in the LH condition; while women evaluated the faces with higher scores in LH than they did in RH condition.
Mutluluğun Yüzdeki İfadesinde ve Algılanmasında Hemisferik Asimetri
(2012) İyilikci, Osman; Çetinkaya, Seda Dural; Gülbetekin, Evrim; Çeti̇nkaya, Hakan; Amado, Sonia
Kişiler arası iletişimde önemli bir rol oynayan mutluluğun yüzsel ifadesine ve algısına ilişkin hemisferik asimetriler farklı tekniklerle çalışılmıştır. Ancak, asimetrinin kaynağının ytizön sahibi mi yoksa, yüzü gözlemleyen kişi mi olduğu henüz açık değildir. Deney I'de mutluluk ifadesinin hangi (sağ/sol) yarı-yüzde daha iyi tanındığı incelenmiştir. Denekler sağ tarafında mutluluk ifadesi bulunan yüzleri daha ifade edici bulmuşlardır. Deney Il'de bu yanlılığın gözlemcideki hemisferik asimetriden mi yoksa poz veren kişinin yüzündeki asimetriden mi kaynaklandığının belirlenmesi hedeflenmiştir. Uyarıcılar çok kısa bir süre ile sol görsel alanda (SOGA) /sağ hemisfere (SAH) veya sağ görsel alanda (SAGA) /sol hemisfere (SOH) sunulmuştur. Yüzler SOGA koşulunda daha htzlı değerlendirilmiş; ancak, SAGA koşulunda daha ifade edici olarak değerlendirlmiştir. Sağ tarafı mutlu olan yüzler SAGA koşulunda daha ifade edici bulunmuştur. Sonuçlar, mutluluk ifadesinin tanınmasında bir sol hemisfer başatlığına ve genel yüz işleme hızında da bir sağ hemisfer başatlığına işaret etmektedir. Ek olarak bulgular, deneklerin değerlendirme süresinde ve değerlendirme puanlarında bir cinsiyet farkı olduğunu göstermiştir. Erkekler, uyarıcıları sağ hemisfer koşulunda, sol hemisfer koşulunda olduğundan daha hızlı değerlendirmişlerdir. Kadınlar ise uyarıcıları, sol hemisfer koşulunda, sağ hemisfer koşulundan daha yüksek puan ile değerlendirmiştir.
