Helping children think: Gaze aversion and teaching
Get PDFLooking away from an interlocutor's face during demanding cognitive activity can help adults answer challenging arithmetic and verbal-reasoning questions (Glenberg, Schroeder, & Robertson, 1998). However, such `gaze aversion' (GA) is poorly applied by 5-year-old school children (Doherty-Sneddon, Bruce, Bonner, Longbotham, & Doyle, 2002). In Experiment 1 we trained ten 5-year-old children to use GA while thinking about answers to questions. This trained group performed significantly better on challenging questions compared with 10 controls given no GA training. In Experiment 2 we found significant and monotonic age-related increments in spontaneous use of GA across three cohorts of ten 5-year-old school children (mean ages: 5;02, 5;06 and 5;08). Teaching and encouraging GA during challenging cognitive activity promises to be invaluable in promoting learning, particularly during early primary years
Visual signals and children's communication: negative effects on task outcome
Get PDFPrevious research has found that young children fail to adapt to audio-only interaction (e.g. Doherty-Sneddon & Kent, 1996), and perform difficult communication tasks better face-to-face. In this new study, children aged 6- and 10 year-olds were compared in face-to-face and audio-only interaction. A problem-solving communication task involving description of abstract stimuli was employed. When describing the abstract stimuli both groups of children showed evidence of face-to-face interference rather than facilitation. It is concluded that, contrary to previous research, for some communication tasks access to visual signals (such as facial expression and eye gaze) may hinder rather than help children’s communication
Don't look now... I'm trying to think
Get PDFWhat was the name of your first headteacher? Stop and think for a while... did you just look to the heavens for the answer? During difficult cognitive activity, for example remembering information, thinking of an answer to a question, planning what we are going to say, and speaking, we often close our eyes, look up at the sky, or look away from the person we are in conversation with. Adults are very good at switching off from environmental stimulation (both live faces and other sorts of visual display) in order to concentrate better. Until recently we knew very little about whether children use gaze aversion in a similar way. This is a potentially important omission, since the efficiency with which children process information influences many aspects of their development, including school progress. In this article I'll describe what our research team at stirling has been doing to investigate children's gaze aversion, including past and current work. children's patterns of gaze promise to yield important cues to their thinking, concentration and mental processing that will be useful to paretns, teachers, psychologists and anyone engaged in assessing children's knowledge and development
Cognitive demands of face monitoring: Evidence for visuospatial overload
Get PDFYoung children perform difficult communication tasks better face to face than when they cannot see one another (e.g., Doherty-Sneddon & Kent, 1996). However, in recent studies, it was found that children aged 6 and 10 years, describing abstract shapes, showed evidence of face-to-face interference rather than facilitation. For some communication tasks, access to visual signals (such as facial expression and eye gaze) may hinder rather than help children’s communication. In new research we have pursued this interference effect. Five studies are described with adults and 10- and 6-year-old participants. It was found that looking at a face interfered with children’s abilities to listen to descriptions of abstract shapes. Children also performed visuospatial memory tasks worse when they looked at someone’s face prior to responding than when they looked at a visuospatial pattern or at the floor. It was concluded that performance on certain tasks was hindered by monitoring another person’s face. It is suggested that processing of visual communication signals shares certain processing resources with the processing of other visuospatial information
Exploring face perception in disorders of development: evidence from Williams syndrome and autism
Get PDFIndividuals with Williams syndrome (WS) and autism are characterized by different social phenotypes but have been said to show similar atypicalities of face-processing style. Although the structural encoding of faces may be similarly atypical in these two developmental disorders, there are clear differences in overall face skills. The inclusion of both populations in the same study can address how the profile of face skills varies across disorders. The current paper explored the processing of identity, eye-gaze, lip-reading, and expressions of emotion using the same participants across face domains. The tasks had previously been used to make claims of a modular structure to face perception in typical development. Participants with WS (N=15) and autism (N=20) could be dissociated from each other, and from individuals with general developmental delay, in the domains of eye-gaze and expression processing. Individuals with WS were stronger at these skills than individuals with autism. Even if the structural encoding of faces appears similarly atypical in these groups, the overall profile of face skills, as well as the underlying architecture of face perception, varies greatly. The research provides insights into typical and atypical models of face perception in WS and autism
Gaze aversion as a cognitive load management strategy in autism spectrum disorder and Williams syndrome
No full textDuring face-to-face questioning typically developing children and adults use gaze aversion (GA), away from their questioner, when thinking. GA increases with question difficulty and improves the accuracy of responses. This is the first study to investigate whether individuals with autism spectrum disorder (ASD; associated with reduced sociability and atypical face gaze) and Williams syndrome (WS; associated with hypersociability and atypical face gaze) use GA to manage cognitive load during face-to-face interactions
Stuck on you: Face-to-face arousal and gaze aversion in Williams syndrome
Get PDFIntroduction: During face-to-face questioning typically developing children and adults use gaze aversion (GA), away from their questioner, when thinking. GA increases with question difficulty and improves the accuracy of responses. We investigate whether individuals with Williams syndrome (WS), associated with hyper-sociability and atypical face gaze, use GA to manage cognitive load and whether physiological arousal is associated with looking at faces. Methods: Two studies were conducted by: i) Recording changes in the participants’ skin conductance levels whilst manipulating task difficulty and gaze direction and ii) Calculating the amount of GA away from the experimenters’ face whilst answering questions of varying difficulty. Results: In study 1, whilst WS was associated with general hypo-arousal, face arousal effects were found for both Williams syndrome and typically developing participants. In study 2, participants with WS showed prolonged face gaze under high task demands, however question difficulty did increase GA. Conclusions: Looking at faces is demanding, even for individuals with WS. Decreased physiological arousal may allow individuals with WS hold face gaze for prolonged periods of time, but looking at faces does increase baseline arousal level. The results are discussed in terms of social skills training and teaching methods appropriate for WS
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The eyes or the mouth? Feature salience and unfamiliar face processing in Williams syndrome and autism
Get PDFUsing traditional face perception paradigms the current paper explores unfamiliar face processing in two neurodevelopmental disorders. Previous research indicates that autism and Williams syndrome (WS) are both associated with atypical face processing strategies. The current research involves these groups in an exploration of feature salience for processing the eye and mouth regions of unfamiliar faces. The tasks specifically probe unfamiliar face matching by using i) upper or lower face features, ii) the Thatcher illusion and iii) featural and configural face modifications to the eye and mouth regions. Across tasks, individuals with WS mirror the typical pattern of performance; with increased accuracy for matching faces using the upper than lower features, susceptibility to the Thatcher illusion and greater detection of eye than mouth modifications. Participants with autism show a generalised performance decrement alongside atypicalities; deficits for utilising the eye region and configural face cues to match unfamiliar faces.. The results are discussed in terms of feature salience, structural encoding and the phenotypes typically associated with these neurodevelopmental disorders
