Abstract

Many sets of human facial photographs produced in Western cultures are available for scientific research. We report here on the development of a face database of Turkish undergraduate student targets. High-resolution standardized photographs were taken and supported by the following materials: (a) basic demographic and appearance-related information, (b) two types of landmark configurations (for Webmorph and geometric morphometrics (GM)), (c) facial width-to-height ratio (fWHR) measurement, (d) information on photography parameters, (e) perceptual norms provided by raters. We also provide various analyses and visualizations of facial variation based on rating norms using GM. Finally, we found that there is sexual dimorphism in fWHR in our sample but that this is accounted for by body mass index. We present the pattern of associations between rating norms, GM and fWHR measurements. The database and supporting materials are freely available for scientific research purposes.

Highlights

  • Humans are a highly social species and possess the ability to identify each member of the species from their facial features

  • Geometric morphometric (GM) landmarks were placed on.BMP versions of the photographs, we provide the.BMP version for each photograph

  • Because the headscarf may obstruct parts of the face, making both facial width-to-height ratio (fWHR) measurement and GM landmark placement difficult, we report the results excluding the five females wearing the headscarf

Summary

Introduction

Humans are a highly social species and possess the ability to identify each member of the species from their facial features. Faces allow perception of identity (i.e., who exactly a target person is) and convey important information about emotions and intentions of the target person and such information critically helps people navigate social interactions [1]. The human face is thought to carry distinct cues leading perceivers to make inferences about the personality and behavioral patterns of the person whose face they are viewing [2]. Whether accurate or not, such inferences are made very rapidly [3]. They are not just fleeting cognitions but are tied to real-world outcomes like mate choice [4] and career success [5,6]. In some senses a person’s face is a “window to his/her soul” [10] as the common saying goes
