People with gelotophobia, or a fear of being laughed at, might have more active and dormant parts of the brain that prevent them from feeling the same emotions as people without the condition, National Tsing Hua University Institute of Learning Sciences assistant professor Chan Yu-chen (詹雨臻) said.
The results of a recent study suggest that gelotophobia might be the result of a relative deficit in the reward system, as analyses showed that gelotophobes exhibited diminished ventral mesocorticolimbic pathway activation in response to hostile jokes, Chan said.
Gelotophobes’ brains generally exhibited greater activity in dorsal corticostriatal projections, suggesting a higher degree of cognitive emotional control, she said, adding that, as a result, there was less activation in response to both hostile and non-hostile jokes.
In contrast, non-gelotophobes exhibited greater activation in response to nonhostile jokes, suggesting a more robust emotional response.
The results show that gelotophobes are unable to process jokes and their brains are unable to generate the subsequent emotional responses of feeling entertained or happiness, she said.
According to other studies, people with gelotophobia comprised 2 to 15 percent of the world’s population, Chan said, adding that England and Asia have a higher ratio of people with gelotophobia than other areas.
“I have lacked a sense of humor and was unable to comprehend jokes since childhood,” Chan said, adding that she began studying the phenomenon five years ago in an attempt to understand her condition and find out how the brain processes humor.
Gelotophobia is mostly an acquired fear, stemming from difficult relationships with parents at a young age and bullying during teenage years or at work, Chan said, adding that these can disconnect emotional control from the brain’s cognitive and emotional management.
However, as it is an acquired phobia, training can help gelotophobes rewire the brain’s cognitive and emotional management to “get” jokes, she said.
The research was conducted using functional magnetic resonance imaging techniques to analyze brain functions and sought to study mental development from the perspective of cognitive neuroscience, Chan said.
The results of the research were published by Scientific Reports early this month.
Former Czech Republic-based Taiwanese researcher Cheng Yu-chin (鄭宇欽) has been sentenced to seven years in prison on espionage-related charges, China’s Ministry of State Security announced yesterday. China said Cheng was a spy for Taiwan who “masqueraded as a professor” and that he was previously an assistant to former Cabinet secretary-general Cho Jung-tai (卓榮泰). President-elect William Lai (賴清德) on Wednesday last week announced Cho would be his premier when Lai is inaugurated next month. Today is China’s “National Security Education Day.” The Chinese ministry yesterday released a video online showing arrests over the past 10 years of people alleged to be
THE HAWAII FACTOR: While a 1965 opinion said an attack on Hawaii would not trigger Article 5, the text of the treaty suggests the state is covered, the report says NATO could be drawn into a conflict in the Taiwan Strait if Chinese forces attacked the US mainland or Hawaii, a NATO Defense College report published on Monday says. The report, written by James Lee, an assistant research fellow at Academia Sinica’s Institute of European and American Studies, states that under certain conditions a Taiwan contingency could trigger Article 5 of NATO, under which an attack against any member of the alliance is considered an attack against all members, necessitating a response. Article 6 of the North Atlantic Treaty specifies that an armed attack in the territory of any member in Europe,
LIKE FAMILY: People now treat dogs and cats as family members. They receive the same medical treatments and tests as humans do, a veterinary association official said The number of pet dogs and cats in Taiwan has officially outnumbered the number of human newborns last year, data from the Ministry of Agriculture’s pet registration information system showed. As of last year, Taiwan had 94,544 registered pet dogs and 137,652 pet cats, the data showed. By contrast, 135,571 babies were born last year. Demand for medical care for pet animals has also risen. As of Feb. 29, there were 5,773 veterinarians in Taiwan, 3,993 of whom were for pet animals, statistics from the Animal and Plant Health Inspection Agency showed. In 2022, the nation had 3,077 pediatricians. As of last
XINJIANG: Officials are conducting a report into amending an existing law or to enact a special law to prohibit goods using forced labor Taiwan is mulling an amendment prohibiting the importation of goods using forced labor, similar to the Uyghur Forced Labor Prevention Act (UFLPA) passed by the US Congress in 2021 that imposed limits on goods produced using forced labor in China’s Xinjiang region. A government official who wished to remain anonymous said yesterday that as the US customs law explicitly prohibits the importation of goods made using forced labor, in 2021 it passed the specialized UFLPA to limit the importation of cotton and other goods from China’s Xinjiang Uyghur region. Taiwan does not have the legal basis to prohibit the importation of goods
