According to the facial feedback hypothesis, people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences. For example, Strack, Martin, and Stepper (1988) instructed participants to rate the funniness of cartoons using a pen that they held in their mouth. In line with the facial feedback hypothesis, when participants held the pen with their teeth (inducing a "smile"), they rated the cartoons as funnier than when they held the pen with their lips (inducing a "pout"). This seminal study of the facial feedback hypothesis has not been replicated directly. This Registered Replication Report describes the results of 17 independent direct replications of Study 1 from Strack et al. (1988), all of which followed the same vetted protocol. A meta-analysis of these studies examined the difference in funniness ratings between the "smile" and "pout" conditions. The original Strack et al. (1988) study reported a rating difference of 0.82 units on a 10-point Likert scale. Our meta-analysis revealed a rating difference of 0.03 units with a 95% confidence interval ranging from -0.11 to 0.16.

Background:The drive towards living well with dementia has resulted in growing recognition of the value of community-based participatory arts. This review aimed to explore their overall impact and holistic benefits for people living with early to moderate stages of dementia. Methods: Using a scoping review methodology and thematic analysis, this review explores relevant literature published between 2008 and 2019. Results: 26 published papers were identified, comprising visual arts, literary arts, comedy, music and dance. The key themes included person-centred, in-the-moment approaches; participation and communication; attention and cognition; social cohesion and relationships; and the role of space, place and objects. Conclusions: There is strong evidence in support of using participatory arts for dementia, regardless of art form. In-the-moment and person-centred approaches were deemed impactful. Further research is needed to explore the important role of setting, material culture and the methodological or theoretical perspectives in participatory arts and dementia research.

Background and aims: Children with autism spectrum condition often have specific difficulties with narrative comprehension, a skill which has a strong association with both concurrent and longitudinal reading comprehension. A better understanding of narrative comprehension skills in autism spectrum condition has the potential to provide insight into potential later reading comprehension difficulties and inform early targeted intervention. In the current study, the main objective was to investigate how differences in the medium of story presentation (paper-book vs. e-book) and differences in story narration (adult narration vs. in-app narration) would influence narrative comprehension in general, and between groups (autism spectrum condition and a receptive language-matched control group). We were also interested in how task engagement (visual attention and communication) differed between group and conditions and whether task engagement was related to narrative comprehension. Method: Forty-two children with autism spectrum condition and 42 typically developing children were read a story either via a paper-book or an e-book with interactive and multimedia features. The e-book was either narrated by the experimenter (adult narrated iPad condition) or narrated by an in-app voiceover (e-book narrated iPad condition). Children's behaviour during storybook reading was video recorded and coded for engagement (visual attention and communication). They then completed two measures of narrative comprehension: multiple-choice questions (measuring recall of literal information) and a picture ordering task (measuring global story structure). Results: Contrary to predictions, we did not find any significant group or condition differences on either measure of narrative comprehension, and both groups demonstrated a similar level of narrative comprehension across the three conditions. We found differences in engagement between conditions for both groups, with greater visual attention in the e-book conditions compared to the paper-book condition. However, visual attention only significantly correlated with narrative comprehension for the typically developing group. Conclusion: Overall, this study suggests that children with autism spectrum condition are just as able as languagematched peers to comprehend a narrative from storybooks. Presenting a story on an iPad e-book compared to a paperbook does not influence narrative comprehension, nor does adult narration of the story compared to in-app narration. However, on-task engagement is linked to narrative comprehension in typically developing children. Implications: Taken together, our findings suggest that e-books may be more successful than paper-based mediums at encouraging visual attention towards the story, but no better at supporting narrative comprehension and eliciting communication.

We investigated symbolic understanding, word-picture-referent mapping, and engagement in children with autism spectrum condition (ASC) and ability-matched typically developing children. Participants viewed coloured pictorial symbols of a novel object (given a novel name) on an iPad in one of three conditions: static 2D images and either automatically or manually rotating images (providing a three-dimensional context). We found no significant difference in word-picture-referent mapping between groups and conditions, however, children who manually rotated the picture had greater on-screen looking time compared to other conditions. Greater visual attention related to more successful word-picture-referent mapping only for the children with ASC. Interactive iPad tasks may increase visual attention in both typical and atypical populations and greater visual attention may benefit word-picture-referent mapping in ASC.

Background and aims Children with autism spectrum condition often have specific difficulties understanding that pictorial symbols refer to real-world objects in the environment. We investigated the influence of labelling on the symbolic understanding and dual representation of children with autism spectrum condition. Methods Children with autism spectrum condition and typically developing children were shown four coloured photographs of objects that had different functions across four separate trials. The participants were given either a novel label alongside a description of the object’s function or a description of the object’s function without a label. Children were then given 30 seconds to interact with an array of stimuli (pictures and objects) in a mapping test and in a generalisation test for each trial. This exploration phase allowed for spontaneous word–picture–referent mapping through free-play, providing an implicit measure of symbolic understanding. Results We found no significant difference in word–picture–referent mapping between groups and conditions. Both groups more often performed the described action on the target object in the exploration phase regardless of condition. Conclusions and implications Our results suggest that a spontaneous measure of symbolic understanding (such as free-play) may reveal competencies in word–picture–referent mapping in autism spectrum condition.
