Abstract Standardised tools to assess a user’s satisfaction with the experience of using chatbots and conversational agents are currently unavailable. This work describes four studies, including systematic literature review, an overall sample 141 participants in survey (experts novices), focus group sessions testing (i) define attributes quality interaction (ii) designing piloting new scale mea...

Experts and novices differ in the coarseness of granularity with which they view the constituent elements of a particular problem or task. Novices are attentive to low-level details. For example, operational details such as finding a particular character on the keyboard or remembering the name of a command involve problem solving. The result is that valuable cognitive resources are diverted fro...

BACKGROUND The purpose of this study was to compare surgically induced astigmatism (SIA) between one-handed and two-handed cataract surgery techniques. METHODS Eighty-eight eyes of 44 patients with no ocular disease other than cataract, who underwent cataract surgery by a single surgeon, were selected for this study. Cataract surgery was performed by coaxial phacoemulsification and intraocula...

Through training, skilled parkour athletes (traceurs) overcome everyday obstacles, such as walls, that are typically insurmountable. Traceurs and untrained novices estimated the height of walls and reported their anticipated ability to climb the wall. The traceurs perceived the walls as shorter than did novices. This result suggests that perception is scaled by the perceiver's anticipated abili...

OBJECTIVE Our aim was to identify the role of the investigators' knowledge of the patient's history of vestibular symptoms (PVH) in the clinical evaluation of the bedside head-impulse test (bHIT). We hypothesized that this knowledge will reduce uncertainty and improve bHIT accuracy when compared to quantitative analysis of the vestibulo-ocular reflex by video head-impulse test (vHIT). METHODS...

Early X-ray fiber diffraction studies have established that the spontaneous gel formation of guanosine 5'-monophosphate (5'-GMP) under slightly acidic conditions (e.g., pH 5) results from self-assembly of 5'-GMP into a helical structure in which hydrogen-bonded guanine bases form a continuous helix with 15 nucleotides per 4 turns. For more than five decades, the sense of this helix is believed ...

This study provides experimental evidence on using expertise of players in a game as a criterion for selecting an equilibrium refinement concept. Research in psychology on differences between experts and novices is used to motivate the hypothesis that forward induction could be a suitable refinement principle for games played by experts. This hypothesis is examined using a game of complete info...
