Department of Psychology, University of California, Los Angeles, USA Abstract Infant face perception provides a nice example of the intersection between biological predisposition (or innate ability) and experience. To assess whether developmental trajectories differed between face memory and face perception, we pooled the data for both tasks, generating an . Any story of face perception typically begins with the recognition of identity, as clearly, the successful recognition of familiar others is fundamental to life quality and survival. We have a wealth of behavioral data showing a similar pattern in tasks that tap more complex and higher order aspects of these cognitive functions, with task performance not reaching adult-like levels until late adolescence. We filtered gray scale animations of facial expressions in ter … Overgeneralization effects in face perception assume a biologically hard-wired response to certain cues that indicate traits such as affiliation or physical fitness; these traits are then generalized to faces that incidentally resemble such cues. Moreover, infants do not initially show an other-race effect nor an inversion effect and this may be due to the need for specific experiences to fine-tune the system. endobj Are we predisposed to attend to, focus on, and interpret cues in faces? This volume: Introduces two young child indices aggregating selected indicators to separately track child outcomes and child circumstances. This volume brings together leading authorities from multiple disciplines to examine the relationship between brain development and behavior in typically developing children. This book is comprised of 21 chapters and begins with an overview of questions about how the face provides information about emotion, with emphasis on evidence based on scientific research (largely in psychology). People’s facial expressions give us important clues regarding how they are feeling and reacting to ongoing events. Faces are special for newly hatched chicks: Evidence for inborn domain-specific mechanisms underlying spontaneous preferences . Twenty-four 12-month-old infants participated in both the main and control experiments. MeSH Updated and expanded to 124 entries, The Cambridge Encyclopedia of Child Development remains the authoritative reference in the field. <> Why is this area of research important to the field of cognitive neuroscience? Five- and 7-month-old infants were tested This particular individual may more often be mistaken to be happy when they are not. This third possibility suggests a similar fine-tuning of face perception abilities. endobj <> We used a standardized method based on the Teller acuity card procedure to test newborns, 6-week-olds, and 12-week-olds with three pairs of face and nonface stimuli modified from previous studies. Bethesda, MD 20894, Help Many more studies are needed in order to for us to understand fully the brain area and developmental path of emotional cue processing in face perception. Specifically, Conspec is a subcortical process involving the superior colliculus and that Conlern is a cortical process involving the primary visual cortex. The cognitive revolution in the 1950s and 1960s led researchers to view the human mind--like a computer--as . 56 0 obj The aim of this book is both to reflect current knowledge of perceptual development and to point to some of the many questions that remain unanswered. The study of perceptual development is now a sophisticated science. PET on the other hand had a low temporal resolution—between 10 seconds and several minutes, depending on the specific PET technique used—which made it impossible to assess cognitive processing in the brain in real time given that most cognitive processes such as face recognition occur much faster than that. This information is then used to form higher-order representations, such as the holistic percept of a face, represented further downstream in the ventral temporal cortex (VTC), including the fusiform gyrus (FG) and fusiform face area (FFA) within it.30 Such higher-order representations are thought to integrate information about a face into a more visual-independent representation. Where and how infants look: the development of scan paths and fixations in face perception. 11 0 obj Infants, children and adults can be particularly interested in viewing faces, and research is starting to reveal how the processing mechanisms for these stimuli might be consistently different from that of typically developing children and adults. (b) Brain regions whose activity differentiated fear and disgust. 68 0 obj <>stream We found that for the simulated acuity the different expressions could be rather well identified at a distance of 30 cm, but when the distance was increased to 120 cm their discriminability was much degraded. The FFA may be disclosed most often because of reasons that have nothing to do with its functional role (e.g., larger blood vessels in the vicinity of this area, reduced fewer magnetic susceptibility artifacts in the middle fusiform gyrus than in other areas). <> Academia.edu is a platform for academics to share research papers. uuid:5f883f94-ac8d-11b2-0a00-e0454e70fc7f Front Hum Neurosci. For example, Gjurgjica Badzakova-Trajkov from the University of Auckland, New Zealand, and colleagues investigated cerebral activation asymmetries during face processing and other tasks in monozygotic twins using fMRI.83 Overall, 21 pairs of twins concordant for handedness, and 21 pairs of twins discordant for handedness, were asked to watch short video clips of faces with emotional expressions, or video clips of moving objects such as a blender. Perception and recognition of faces are fundamental cognitive abilities that form a basis for our social interactions. CONLERN. Rather, a face-selective cluster may concern a subset of an anatomical area, and there is no reason to expect that all individual human brains have the same amount of well-identified face-selective clusters in the VOT cortex. <> Cortical areas that give strong responses in normally sighted observers when viewing faces and objects (lingual and fusiform gyri) were largely inactive in MM. Infant discrimination of faces was Batty and Taylor (2006) investigated the N170 response for faces showing six different emotions (happiness, surprise, sadness, fear, anger, and disgust) as well as a neutral face in a large sample (82) of children between the ages of 4 and 15 years. Recall that, in infants, investigations of face processing used ERP measures and, in particular, evaluated the modulation of the N170 component in response to faces as compared to other visual objects. Work with nonhuman primates have identified face-responsive cells in the inferior temporal cortex. 8 0 obj For the face-gender categorization task, Sergent found that the right ventral extrastriate cortex played a critical role for face perception. On the links among face processing, language processing, and narrowing during development. Human face perception has been the focus of many neuroimaging and behavioral investigations in adults, in infants, and throughout childhood and adolescence. Ciarrusta J, O'Muircheartaigh J, Dimitrova R, Batalle D, Cordero-Grande L, Price A, Hughes E, Steinweg JK, Kangas J, Perry E, Javed A, Stoencheva V, Akolekar R, Victor S, Hajnal J, Murphy D, Edwards D, Arichi T, McAlonan G. JAMA Netw Open. From: Fundamentals of Cognitive Neuroscience (Second Edition), 2018. Pricing Free. Some kinds of holistic object perception appear to be comprised by visual deprivation, but the evidence is complex. (2001) study, but she was not tested explicitly for holistic object perception. The book also challenges the conventional wisdom that race is purely a social construction by demonstrating that a common set of abstract principles underlies all systems of racial thinking, whatever other historical and cultural ... It is also clear that the newborn infant is an extremely competent learner. They suggested that interpreting complex emotional information in human faces was a slow-to-mature process that was not fully realized even in middle teenage years. endobj Clearly, more work is needed to flesh out the underlying mechanisms of face perception. Looking at unfamiliar faces and indicating their gender. Behavioral Visual categorization is recorded neurally in 4-mo-old infants presented with rapid trains of natural images of nonface objects. <> <> The primary system for processing static features, such as face identity, is dominant in the right hemisphere and is located along the hierarchical ventral-visual “what” stream responsible for visual stimulus recognition. endobj On the other hand, a case study of MM, a man who lost his vision at 3.5 years and had cataract replacement nearly 40 years later, revealed marked deficits in object perception skills (Fine et al., 2003). Here, we highlight two recent studies of emotional cues in faces with children: one study uses fMRI to elucidate brain regions employed in decoding emotional face cues and the second utilizes the EEG N170 component to investigate the time course of emotional cues in face processing. Kalick et al.196 showed through a longitudinal analysis of attractiveness and health that the two were unrelated, despite relatively attractive individuals being rated as healthier than their peers. January 2003. The critical period for development of holistic processing, therefore, appears to be exceedingly brief. - found equal preference for face and non face stimuli arranged in an 'up- down asymmetry' pattern. This volume considers how children's thinking evolves during development, with a focus on the role of experience in causing change. endobj Bernard J. Baars, Nicole M. Gage, in Cognition, Brain, and Consciousness (Second Edition), 2010. In both groups there was no twin pair in which both individuals showed leftward activation asymmetry. Because gender-specific emotion overgeneralization effects will be mentioned in the next section, here we discuss these principles in more general circumstances by reviewing overgeneralization effects for attraction and specific emotions. application/pdf Figure reproduced with permission from Caldara R, Seghier ML, Rossion B, Lazeyras F, Michel C, Hauert C-A. This volume is devoted mainly to anatomical and functional development of neural circuits and neural systems and cognitive development. This book on face perception is one of the most researched areas in infancy and early childhood, because of the enormous information that the face conveys to its viewer, both in terms of the recognition of individuals and in the expressive information that faces convey. It is also clear that the newborn infant is an extremely competent learner. Habituation, novelty preference, and visual paired comparison paradigms are typically used to investigate face perception in young infants. The left side of each panel corresponds to the left of the brain. Simply select your manager software from the list below and click on download. Here, we studied whether infant-directed speech (IDS), could affect the processing of a face with direct gaze in 4-month-olds. The third possibility relies on speech perception as a model. Tobii Pro Webinar: Face Perception in Infants and Children. 14.26, brain activation for faces appears to be more focal and more face-selective during childhood and adolescence. (1996). Looking at objects and indicating whether the objects were natural or man-made. One central finding from a variety of data sources (histological, pathological, neuroimaging) is that the cortical regions subserving these high order cognitive functions have a prolonged developmental path extending to mid- to late adolescence. The measurement of perception on each trial also allows for within-subjects comparisons of how different emotional cues affect infant face perception. Interestingly, infants at 2–3 months show no signs of the inversion effect (Cashon and Cohen, 2003), and sensitivity to some kinds of holistic information in faces is not adultlike until several years after this time, as noted previously. endstream Putting these two bodies of information together in order to map brain development onto cognitive function remains a challenge for the developmental cognitive neuroscientist. Child Development Perspectives, 8, 65 - 70. The development of face memory and face perception. During the first year of life, infants undergo perceptual narrowing in the domains of speech and face perception. 6-month-old infants were shown a concave mask under monocular and binocular viewing conditions and the direction of their reaches toward the mask was recorded. The effect of facial expression on contrast sensitivity: A behavioural investigation and extension of Hedger, Adams & Garner (2015). <> Webinar In this one hour free webinar, we will focus on the research that examining infants' perceptual abilities. While we have a general notion of how language emerges in young children, the cortical mapping of complex language systems is still being worked out in adults, with less known about the patterns of emergent language. Investigating brain regions that may be specialized for perception of our species-specific faces may shed light on the nature versus nurture debate. The frequency of faces in these scenes declined markedly with age: for the . For example, someone who is perceived as angry may be mistaken to possess a low affiliative nature. Studying face processing during development may help us determine how genetic predisposition interacts with experience. This book is a unique contribution to research and to the literature on clinical neuroscience. What have we learned about the development of language, executive function, and social cognition in childhood and adolescence? 109 CHAPTER 3 Infant Visual Perception PHILIP J. KELLMAN and MARTHA E.
