Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
They are then randomly allocated to one of the two following conditions. Participants are primed either with age stereotypes or non-age stereotypes words by implicit priming intervention in the context of a reaction task prior to the episodic memory tasks. Other measures such as demographic variables and social participation rate are collected by questionnaire during the delayed recall interval.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Age-related priming
Participants received a review of the profile of their social participation. They also received psycho-education about memory components. They were give given memory tests with age-related primes.
Age-related stereotyping priming
The priming intervention was performed using the E-prime 2.0 software (Psychology Software Tools, Pittsburgh, PA). To ensure the primes flashed on screen were beyond awareness, the similar adjustment procedure was taken (see Levy, 1996; Stein et al., 2002). After the trial block, participants were asked to try to report any words viewed during each trial. The stimulus onset asynchrony (SOA) will be reduced or enhanced whenever 2 words or above were correctly reported or no single word could be reported respectively. The priming SOA for this study ranged from 32 ms to 208 ms (M = 98.70 ms. SD = 48.60).
Non-age related priming
Participants received a review of the profile of their social participation. They also received psycho-education about memory components. They were give given memory tests with NON age-related primes.
Non age-related stereotype priming
he priming intervention was performed using the E-prime 2.0 software (Psychology Software Tools, Pittsburgh, PA). To ensure the primes flashed on screen were beyond awareness, the similar adjustment procedure was taken (see Levy, 1996; Stein et al., 2002). After the trial block, participants were asked to try to report any words viewed during each trial. The stimulus onset asynchrony (SOA) will be reduced or enhanced whenever 2 words or above were correctly reported or no single word could be reported respectively. The priming SOA for this study ranged from 32 ms to 208 ms (M = 98.70 ms. SD = 48.60).
