A researcher is interested in whether older adults (OA) are better or worse in accessing social- intentional judgments from movements compared to younger adults (YA). Twelve older adults and twelve younger adults were presented with 25 trials of different movements that were recorded using the motion capture technology. Twenty-five different movements were captured indicating a type of social-interaction (e.g., shaking hands, helping each other carrying a box, etc.) between two people. After each trial, participants were asked what the intention of the characters were. Higher Scores indicate higher success in social judgments from movements. Using the 4-step hypothesis testing, what should this researcher conclude?

Question
A researcher is interested in whether older adults (OA) are better or worse in accessing social-
intentional judgments from movements compared to younger adults (YA). Twelve older adults and
twelve younger adults were presented with 25 trials of different movements that were recorded
using the motion capture technology. Twenty-five different movements were captured indicating a
type of social-interaction (e.g., shaking hands, helping each other carrying a box, etc.) between two
people. After each trial, participants were asked what the intention of the characters were. Higher
scores indicate higher success in social judgments from movements. Using the 4-step hypothesis
testing, what should this researcher conclude?
