It has shown that the contextual information influenced judgements of the target facial expression. In this study, we systematically investigated how the surrounding emotional faces influenced expression perception by using categorization, discrimination, and rating tasks. In the categorization task, the participants had to categorize the target faces as happy or angry while the target facial expressions morphed to five levels varying between angry and happy faces. We also measured the response time in the categorization task. In the discrimination task, we required participants to discriminate a facial expression (either happy or angry) from a neutral face. The target morphed between happy and neutral faces or angry and neutral faces. In the rating task, the participants needed to rate the intensity of the angry and happy target faces. In all of the experiments, the targets were surrounded by five different types of face conditions (happy, angry, neutral, inverted neutral, and absent [baseline] faces). Despite the fact that the results showed that the surrounding conditions did not affect categorization, discrimination, and intensity judgement, they had a main effect on the reaction times during the categorization task. Hence, participants had the fastest reaction times when identifying target faces with happy surrounding conditions.

Building a culturally-calibrated face database with variations in identity, expression, pose, and lighting, can meet the demand of a multitude of face research. The present study represents an extension of our previous effort in this regard (Shyi, Huang, & Yeh, 2013), where subsequent studies have exposed its limitations in fulfilling the requirements placed by experimental manipulations. 6,600+ face photos, varying in terms of expression, pose, lighting, and gaze direction were taken from a group of 36 female and male models. About half of them (3,300+) were rated by another group of 120 participants to ensure that each face image was rated by at least 10 different participants. We then categorize each images into one of the seven basic emotions in terms of intensity and polarity. In order to compare the current and the previous databases, we conducted analyses to examine how pose, intensity and direction of lighting may affect the ratings and entropy values associated with each image. The overall results from these analyses show patterns remarkably similar to the previous database. Taken together, we consider the current database and the previous database are empirically equivalent, and can be linked into a larger and more useful source for face research.

In developing the fifth core knowledge about social partners, race is an important factor biasing children to form social affiliations. The present study explored the development of the race-based social preferences in 3- to 8-year-old Taiwanese children. In Experiment 1, twenty-one 3-4 year-olds viewed three simultaneously presented video clips modeled by a Taiwanese (own race, high social status, in-group), a Southeast Asian (near race, low social status, out-group) and a Caucasian (other race, high social status, out-group) young female smiling at them. Children were instructed to give a toy to their most preferred and second preferred individuals, and children preferred the Taiwanese actress the most (50%). In Experiment 2, twenty-two 5-6 year-olds viewed the same videos and were instructed to choose their most preferred and second preferred persons as friends. They preferred the Taiwanese actress the most (69%). In Experiment 3, twenty-one 7-8 year-olds performed the same task as in Exp.2 and they preferred the Caucasian actress (57%) the most and the Southeast Asian actress the least. In sum, our findings suggest that a rudimentary race-based social preference (or prejudice) seems to emerge early in childhood. These results provide a cross-cultural exploration about the development of race-based social judgments.

The Importance of the First Fixation for Recognising Own- and Other-Race Faces: An Eye-Tracking Study
Presentation Number:P1.07 Abstract Number:0089 |
Hoo Keat Wong 1, *, Ian Stephen 2, David Keeble 11University of Nottingham Malaysia Campus 2Macquarie University
Hills and Lewis (2006) reported that the own-race bias (ORB) in face recognition was reduced by cueing Caucasian participants to the lower region of African faces. However, recent empirical studies have failed to replicate this finding. This cross-cultural study investigated whether shifting initial attention to different facial regions affects own- and other-race recognition performance. In a classic yes-no recognition task, Malaysian-Chinese, Australian-Caucasian, and African participants were presented with a series of Chinese, Caucasian, and African faces that had facial regions (i.e., eyes, nose, mouth) cued with fixation crosses. Split analyses by race groups revealed that there was a pronounced ORB only in Caucasian participants. Most importantly, cueing Chinese participants to the nose region and Caucasian participants to the eyes and nose regions enhanced their subsequent recognition performance compared to cueing to the mouth region. These results suggest that immediate fixations directed to the upper facial regions, especially the nose region, somewhat encourage holistic face processing and/or decrease the engagement of featural processing, and may enhance the encoding of individuating diagnostic features for recognition.

Yawning face detection sensitivity and yawning contagion
Presentation Number:P1.11 Abstract Number:0059 |
Hiu-ming Chan 1, Chia-huei Tseng 2, *1University of Cambridge 2Tohoku University
Contagious yawning—the urge to yawn when thinking about, listening to, or viewing yawning—is a well-documented phenomenon in humans and animals. While clinical studies have suggested the association between empathy and contagious yawning frequency, whether there is a perceptual component is not studied comprehensively yet. In this study, we examined influences from perceptual factors (i.e., individuals’ eye gaze pattern and perceptual detection sensitivity to yawning, happy, and angry faces) on 41 non-clinical adults. We induced contagious yawning with a 5-minute video and 20 yawning photo stimuli, and we measured participants’ eye gaze patterns, perceptual detection thresholds to human yawning and facial emotions (happy or angry), and autistic traits (with the Autism-Spectrum Quotient Questionnaire). We found two factors associated with yawning contagion: (1) those more sensitive to detect yawning, but not other emotional expressions, displayed more contagious yawning than those less sensitive to yawning expressions; (2) female participants exhibited significantly more contagious yawning than male participants. We did not find an association between autistic trait and contagious yawning after controlling for gender and yawning sensitivity. Our study offers a working hypothesis for future studies, in that perceptual encoding of yawning interacts with susceptibility to contagious yawning.

Motion Perception
Vertical size disparity processing on elements moving in opposite directions
Presentation Number:P1.13 Abstract Number:0091 |
Yuta MIYANISHI 1, *, Hirohiko KANEKO 11Tokyo Institute of Technology
It has been reported that vertical disparities distributed in a certain spatial and temporal region are pooled to produce stereoscopic perception of the curvature, inclination, and slant of a surface. However, Duke & Howard (2005,2012) reported that vertical disparities in the same region are not pooled when they are separated in depth defined by horizontal disparity. In other words, vertical disparity is processed in each depth region specified by the horizontal disparity.
We investigated the effect of a depth separation defined by relative motion, instead of horizontal disparity, on the vertical disparity pooling. The stimulus consisted of two sets of dots, and they were uniformly intermingled. They had opposite signs of vertical size disparity and opposite directions of motion. Their horizontal disparities relative to the screen were kept at zero. Observers responded perceived slants of one or two surfaces of the stimulus.
As a result, when the relative speed of the two set of dots was high, two separated slants were perceived. When the relative speed was adequately low, single surface was perceived. The transition of slant perception seemed to be dependent on the relative speed itself, regardless of the magnitude of depth separation produced by the relative motion.

Randomly Updating Images on Coherence Global Motion
Presentation Number:P1.17 Abstract Number:0067 |

Glass (1969) patterns are formed by pairs of random dots (dipoles) which could carry a powerful percept of global structure. The perceived motion direction of a dynamic Glass pattern is influenced by orientation of the dipoles (Krekelverg et al., 2003). Here, we investigated whether just updating random dots would form a specific global motion. Five types of moving stimuli, including linear, random, concentric, radial and updating, were shown through either a circle or square aperture. The task of the participants was to judge the perceive strength of concentric, linear, radial movement a 7-point Likert scale for each stimulus. In all viewing conditions, participants indeed showed a response bias toward concentric motion. The bias was particular strong in the circle aperture. Such effect of aperture shape was the most pronounced for the linear motion stimuli. These results show that just updating the position of dots in a random dot image is sufficient to generate a percept of concentric global motion. The effect of dipole orientation in the previous dynamic Glass pattern studies may be a secondary effect.

The effect of training paradigm in Greeble expertise acquisition: A multi-voxel pattern analysis (MVPA) approach
Presentation Number:P1.18 Abstract Number:0095 |

The fusiform face area (FFA) has often been speculated as a brain region that is specialized for face perception and recognition. While it is generally believed that the FFA responds selectively more to facial stimuli than other objects, the expertise hypothesis proposes that the FFA may participate in the processing of any object class that is trained to be processed at the subordinate or individual level. Next poster gives the FFA evidence of how two different training regimes (Gauthier et al., 1997, Vision Res., 37(12), pp. 1673-82; vs. Gauthier et al., 1998, ibid., 38/15, pp. 2401-28) yield different FFA responses. The multi-voxel pattern analysis is used to distinguish the patterns of FFA activity between Greebles and other stimuli (“Faces” and “Objects”), and we demonstrate that activity patterns of localized FFA perform better at distinction of “Faces vs. Greebles” in before-than after-training does, and in “Greebles vs. Objects” better in after- than before-training does. In both case, the Gautheir 97 paradigm has shown more prominent distinction results than the Gauthier 98 paradigm. In addition, searchlight information mapping is employed to identify other brain regions that can provide information concerning the neural representation of distinct object classes.

Perceptual Expertise Predicts Both Gray Matter Thickness and Density In The Human Fusiform Gyrus: A Cross-Country MRI Study On Bird Experts
Presentation Number:P1.19 Abstract Number:0114 |
Yi Lin 1, *, chun-chia kung 1, nian-ting yang 11ncku
In one recent study, cortical thickness (CT) of car experts' Fusiform Face Area (aka FFA) were correlated with their face and object (car) performance [McGugin, et al. (2016) JoCN 28, pp. 282-294].To both extend this finding from car experts to experts of other domain, and also expand the CT and cortical volume,in study1 we reanalyzed our previously acquired birder MRI data (N=27 Caucasians), with both audiovisual and visual dprimes as their expertise measure.The results showed that significant correlations were found in both voxel density and CT between both audio and visual d', especially in bilateral fusiform gyrus,dorsal anterior and posterior cingulate gyrus, etc.After partialling out the age confound, controlling for the high correlation between expertise and age, these results still hold.In study2,we corroborated the similar results MRI data (N=20, with only visual dprimes) acquired in Taiwan.Lastly, the joint analyses combining both America and Taiwan data (N=47) showed that the left fusiform gyrus remained highly correlated,further strengthening the role of FG in expertise.Despite of slight disparities,the brain regions are overall highly similar across VBM- and CT-expertise correlations,not only extending the previous CT-expertise in car to bird experts,but also expanding the CT-expertise to VBM-expertise correlations,deepening the interconnection between experience and brain structure.
