ANALYSIS OF PERSONALITY TRAITS IN CHINDONGO DEMASONI AND THEIR RELATIONSHIP WITH COGNITIVE ABILITY
摘要
Abstract
To investigate the relationship between personality traits and cognitive abilities in fish,this study used juve-nile Chindongo demasoni,a highly social cichlid species,as the model organism.Through associative learning training and tests based on a"color-food reward"paradigm,we assessed cognitive performance and analyzed its correlation with three personality traits:activity,boldness,and sociability.The results showed that:(1)Activity and boldness were positively correlated in Chindongo demasoni(P=0.024),supporting the Behavioral Syndromes Hypothesis;(2)The fish successfully formed associations between color cues and food rewards through associative learning,with the correct choice rate increasing significantly over training days(P<0.001);(3)Sociability was positively correlated with cogni-tive performance,as measured by the correct choice rate during the test phase(P=0.006),while no significant relation-ship was found between cognitive performance and either activity or boldness.The link between sociability and cogni-tive ability supports the Social Brain Hypothesis,suggesting that for social fish,the demand to process complex social information may be an important driver in the evolution of cognition.关键词
