This pattern of self-face advantage persisted in European Americans during the low-threat condition, while Chinese participants regained self-face advantage during the low-threat condition.
However, in low-threat conditions, adolescent-stressed rats took 106% longer to initiate foraging, but consumed the same amount of food as unstressed rats, which contrasts with prior hypotheses predicting decreased functionality in low-threat conditions.
However, we did not find any difference in performance under low-threat conditions between adolescent-stressed and unstressed adult animals.
These hypotheses often predict that early stress will impair performance in low-threat conditions later in life.
Here we discuss these results in the framework of the Yerkes-Dodson law, which describes a context-specific relationship between performance and arousal that we have modeled using high and low-threat conditions.
we tested rats in a moderately challenging, problem-solving foraging task that required varying motor actions and object manipulations under both high-threat conditions (auditory and visual predator cues, bright light) and low-threat conditions (standard laboratory conditions, dim red light).
To understand why stress during adolescence may affect performance in high-threat but not in low-threat conditions, we discuss our findings in the framework of the Yerkes-Dodson law, a key precept of psychology that has been used for over a century to describe how stress affects performance.
In the low threat photo conditions a significant main effect of health text was found, F 1, 62) = 51.04, p < .001, ηp = .45.45
For the low threat photo conditions again a significant main effect of health text was found, F 1, 62) = 44.27, p < .001, ηp = .42.42
In contrast, American participants maintained a self-face RT advantage in both low and high threat conditions, in accordance with our hypothesis that self-processing in Americans is not influenced by the social threat of one's boss.
