Profiles on the Orientation Discrimination Processing of Human Faces

Abstract

Face recognition is a crucial subject for public health, as socialization is one of the main characteristics for full citizenship. However, good recognizers would be distinguished, not only by the number of faces they discriminate but also by the number of rejected stimuli as unfamiliar. When it comes to face recognition, it is important to remember that position, to some extent, would not entail a high cognitive cost, unlike other processes in similar areas of the brain. The aim of this paper was to examine participant’s recognition profiles according to face position. For this reason, a recognition task was carried out by employing the Karolinska Directed Emotional Faces. Reaction times and accuracy were employed as dependent variables and a cluster analysis was carried out. A total of two profiles were identified in participants’ performance, which differ in position in terms of reaction times but not accuracy. The results can be described as follows: first, it is possible to identify performance profiles in visual recognition of faces that differ in position in terms of reaction times, not accuracy; secondly, results suggest a bias towards the left. At the applied level, this could be of interest with a view to conducting training programs in face recognition.

“…However, it was possible to identify two different profiles across participants, in a homogeneous way across countries. This is an alternative and analytical strategy to traditional analysis ( 26 ), that might shed light on common processes across country measures.…”

Word and Face Recognition Processing Based on Response Times and Ex-Gaussian Components

“…Another limitation of the study is that not all the perceptual characteristics of the stimuli have been explored. Faces have been presented in black and white resolution to facilitate comparisons with names, but in their more ecological environment, faces vary in color, expression, and position [ 59 , 60 ]. Ultimately, this question could be related to theories of interest to entropy approaches.…”

“…Research in this field continues to debate how overlapped and dissociated these processes are, as face recognition is believed to be an innate process, while name recognition is based on reading, which must be learned. In this way, literature has showed how the impairment on one process might not affect the other and vice versa [37], or even how differences in early development of areas of specialization exist for these processes [38,39]. For this reason, how stable these differences are of interest.…”

“…Its advantage does not exclude traditional analysis, rather, it supports and deepens hypothesis testing and probabilities. Another line of research is related to neural approaches, cluster analysis, or deep learning, with numerous applications in technology and natural science [39,[44][45][46][47][48][49].…”
