Brief Summary

Memory performance is shown to be affected by age stereotypes among older adults. The purpose of the study is to examine the effects of age stereotype primes on episodic memory using priming intervention. The moderating effects of social participation is also examined.

Conditions

Aging Well; Memory Loss

Keywords

Age stereotypes; episodic memory; social participation

Outcome Measures

Primary Outcomes (1)

• Hong Kong List Learning Test

  The Hong Kong List Learning is a validated tool for assessing episodic memory for aged Chinese speaking adults (Chan, 2006). It was further taken for investigating differences among older adults with normal cognitive ability and older adults with mild cognitive impairment (Yeung et al., 2016). The random control list was taken in this study. It comprises 16 words formed by four categories:

Study Arms (2)

Age-related priming

EXPERIMENTAL

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.

Other: Age-related stereotyping priming

Non-age related priming

ACTIVE COMPARATOR

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.

Other: Non age-related stereotype priming

Interventions

Age-related stereotyping priming OTHER

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).
