BiB - Believing in BERT

This study investigated the benefits of an affective physical interaction with a humanoid robot by comparing an expressive and communicative condition with a faster, less error prone but non-communicative one.

Prior to the experiment, participant information was collected via a survey taken online on Survey Monkey. The participants were then asked to interact directly with the BERT2 robot in an omelette making task. Following this, they were asked to complete a post-experiment survey, also taken online on Survey Monkey.

In the online pre-experiment survey 23 participants (n = 21, two sets of data were discarded and not used in the analysis as the robot was malfunctioning to the point where participants could not complete the task) gave their age, occupation, level of education and answered questions about their experience with and attitude to robots. The results are not provided here as there is reason to believe participants could be identified by these data sets. 

The experiment was recorded on a video camera. Ethical consent was conditional on the destruction of this data after analysis.

The post-experiment survey consisted of a NASA TLX questionnaire, with two additional Likert scale measures - for trust and satisfaction.  These two measures, together with those for frustration and temporal demand, underpin our research and are referred to in Figure 2 and Table 2 in [1].  
	The column headings in the files that contain the data collected through the post-experiment survey refer to the corresponding questions (using question numbers) in that survey and provide the results for each of the three different versions of the BERT2 robot, A, B and C.
