cognition in a state of imbalance, inducing
experiences of fear and stress, which in turn lead to
negative consequences (Dong et al., 2022). Similarly,
activating negative meta-stereotypes does not always
lead to negative outcomes; it can also have positive
effects, known as the resistance effect of activating
negative meta-stereotypes. The resistance effect
refers to the situation where, after activating negative
meta-stereotypes, individuals perceive the full extent
of negative evaluations and may counter these
evaluations by engaging in positive behaviors to
maintain their group image or prove their capabilities
(Dong et al., 2022).
In 2015, Sun investigated whether the working
memory capacity of migrant children is affected by
negative meta-stereotypes’ activation. In the study,
the approach employed to elicit negative meta-
stereotypes mirrored the technique utilized for
positive ones. This entailed prompting participants to
verbalize the potential negative perceptions that an
outgroup could harbor towards their own ingroup.
Concurrently, the control group was tasked with
responding to a query concerning the advancement of
the nation's scientific and technological progress (He
et al., 2024, Sun et al., 2015). The research proceeded
to assess working memory capacity through the N-
back task, utilizing black solid geometric shapes—
circles, triangles, and rectangles—as visual stimuli.
The experimental protocol included a 500ms interval
for fixation, a period allocated for participant
responses, and a subsequent 500ms interval with a
blank screen. The tasks were categorized by cognitive
demand, with the 0-back, 1-back, and 2-back variants
corresponding to low, medium, and high cognitive
load, respectively. Furthermore, the study's repeated
measures analysis of variance (ANOVA) revealed
that the activation of negative meta-stereotypes
exerted a substantial influence on children's working
memory performance. The analysis also highlighted
a significant main effect attributed to the varying
levels of task difficulty (Sun et al., 2015).
Furthermore, it was observed that participants who
engaged with negative meta-stereotypes exhibited
poorer performance in working memory exercises
across all three tiers of task complexity when
contrasted with the control group that maintained a
neutral stance (Sun et al., 2015).
Li and colleagues conducted a study in 2021 of
how activating negative meta-stereotypes can impact
on the working memory of elderly individuals. This
was the first study to use the N-back task to examine
the effects of activating negative meta-stereotypes on
the cognitive performance of elderly adults under
different cognitive load tasks, this study also used
graphics as stimulus materials (Li et al., 2021).
Researchers examined whether it was possible to
manipulate the activation of negative meta-
stereotypes in the elderly through instructions and the
subsequent answers provided by the elderly based on
those instructions. Emotional responses when
negative meta-stereotypes are triggered were
assessed through emotional scores and physiological
indicators such as skin conductance and skin
temperature. The findings of the study indicated that
a substantial disparity existed in the irritability scores
between the negative meta-stereotype activation
group and the non-irritable group, while there was no
significant difference in the scores of other negative
emotions. Consequently, the repeated measures
ANOVA disclosed that there was no significant
interaction effect between the group and the level of
task difficulty. However, both the difficulty level and
group membership had significant main effects. The
research demonstrated that individuals in the group
that activated negative meta-stereotypes scored lower
on cognitive tasks compared to those in the group
without such activation, thereby validating the notion
that activating negative meta-stereotypes has a
reciprocal impact on cognitive performance.
Additionally, the study found that task difficulty did
not have a moderating effect on the activation of
negative meta-stereotypes (Li et al., 2021). Previous
studies have shown that activating negative meta-
stereotypes can lead individuals to desire a change in
negative evaluations, thereby exhibiting resistance to
these negative traits and demonstrating a positive side
to improve intergroup relations (Dong et al., 2022).
However, there is currently no research on whether
activating negative meta-stereotypes might enhance
an individual's cognitive abilities, thereby producing
a resistance effect.
3.2 The Mechanism of Negative
Meta-Stereotypes’ Affect Working
Memory
Regarding the mechanism of activating negative
meta-stereotypes’ impact on working memory, the
threat effect of activating negative meta-stereotypes
can still be explained by the resource limitation
theory. The resource limitation theory posits that
negative meta-stereotypes trigger physiological stress
responses and induce self-monitoring, which
consume an individual's cognitive resources, leading
to poorer performance on subsequent cognitive tasks
(Dong et al., 2022). Studies on the reduction of
working memory capacity in the elderly caused by the
negative meta-stereotypes’ activation suggest that the
