Background The coronavirus disease (COVID-19) pandemic has resulted in a significant increase in the number of people seeking online support and information, particularly on social media. Nevertheless, the nature and trend of internet information, as well as its accuracy, are questionable. This study aimed to assess and compare the content, type/form, and degree of accuracy of breastfeeding information on Facebook before and during the COVID-19 pandemic (n = 288/phase). Methodology The data were gathered from Malaysian public and group/page Facebook posts (n = 456). Keyword searches were conducted using Malay and English breastfeeding terms. The dataset was screened and entered into a structured codebook. The Delphi approach was used to assess the accuracy of posts’ content performed by breastfeeding experts. Results Sharing personal experience (53.2%) was the most common topic in breastfeeding-related posts, followed by seeking questions (39.3%) and knowledge (8.0%). Sharing personal stories and knowledge posts were higher during COVID-19 than before (p = 0.001), although the seeking questions category was higher before the pandemic (p = 0.001). Most information posted was in text form (94.5%). About half of the posts (46.5%) were misleading, while (43.7%) were accurate. There was a significant difference in the accuracy of online posts before and during the COVID-19 pandemic (p = 0.001). Conclusions Compared to the pre-pandemic phase, forms/types of information on Facebook remained consistent, whereas the breastfeeding information content and its degree of accuracy differed during the pandemic.We need to explore other aspects of breastfeeding online content as well as its engagement, especially during a pandemic. Knowing the infant feeding-related topics that have been discussed and questioned on social media, as well as the accuracy of the data, allows policymakers and scientific communities to plan strategies for spreading credible breastfeeding information online. This includes creating interactive online media types of visual guidelines, web resources, and breastfeeding apps.

Children like to draw, but how easy is it for them to draw with a touch screen device? More specifically how do children adapt the way that they draw to the device and to their own limitations? Recent work has shown that while children seem to like using tablets they have specific difficulties. For example, they make multi-touch errors when only single touch actions are required. We are at the start of a project to investigate these issues. In the current article we review our theoretical and empirical perspective, which is derived, in part, from the cognitive psychology of human movement control.

Past work on children's drawing from the "process oriented" approach focused more on how children draw without considering what and why they draw. Both what and why under the "product oriented" approach need to complement the question of how in order to understand children's drawing behaviour better. The work of this thesis focuses on the"process oriented" approach that deals with the motor process of children's drawing without neglecting the importance of the "product oriented" approach.This thesis seeks a better understanding on psychological processes involved in drawing and drawing development in children to study their drawing behaviour. This is why the thesis is reviewed under the theoretical framework of Adaptive Interaction. This framework (Chapter 2: Background and Theoretical Framework) studies children's drawing through a utility maximization approach that derives its explanatory power from three components of human behaviour; ecology, utility and information processing mechanisms.As such, it raises the following questions: (1)"How would children draw on a tablet given that they have cognitive and motor limitations?"; (2)"Why would children draw on a tablet given that there are limitations on tablet and drawing software?" The framework helps to provide an explanatory and predictive account of children's adaptation of drawing strategies on a tablet. The empirical work of the framework is conducted to answer the following research questions: (1)"How do children adapt their drawing strategies according to their own motor variability and to the limitations of tablet and drawing application?";(2)"How do a child adapt to the drawing actions according to his/her own motor variability?"; and (3)"Does adaptation to motor variability explain age-related changes in drawing performance?";To answer these questions, I conducted empirical studies (Chapter 3 to 6) to examine how children adapt their drawing actions to their own motor variability and to extrinsic motivations (rewards). My study consisted of drawing tasks that tested the model of movement planning based on the Statistical Decision Theory. The idea was to see how children act as ideal drawing planners when choosing movement trajectories on touch surfaces. I derived predictions of the hypothesis from children's drawing on a touch screen with regions carrying reward and penalties. When a penalty region is placed near to a target region, adults are known to alter their motor plan. In particular, they shift their aim point to avoid the penalty region. The model predicts shifts in subjects aim point in response to changes of reward and penalty structures within the drawing environment.The result of my studies show that children make near optimal adaptation to subjective rewards, their own cognitive and motor limitations and to the limitations of tablet and tablets drawing software. The work reported here shows that a child's strategies for drawing on a tablet can be understood as a Bayesian adaptation to movement variability, motivation and limitations of the...
