Study about skin area and gender in tickishness

The study “The Importance of Skin Area and Gender in Ticklishness” by Svebak Sven examines how gender and specific body areas influence ticklishness, employing an innovative methodology involving feather stimulation. The research focused on students, analyzing body areas typically exposed when wearing a swimsuit.

The experiment was video-recorded to assess both involuntary muscle contractions and laughter, as well as the subjective sensation of ticklishness. The findings revealed that women laugh more frequently than men when tickled, regardless of the tickler’s gender. However, the subjective sensation of ticklishness and muscle contractions were more intense when the tickler was of the opposite gender.

The most ticklish areas identified were the ankles, knees, and sides of the body. The study suggests that laughter may reflect gender-related stereotypes in socio-expressive behavior, whereas involuntary muscle reactions and the subjective ticklishness sensation might indicate a biological component of playfulness, particularly in mixed-gender interactions.

The participants in the study were grouped according to a factorial design that considered the gender of both the tickler and the tickled subject. This led to a random distribution into four subgroups:

Female tickler/Female tickled (N = 13)
Female tickler/Male tickled (N = 16)
Male tickler/Female tickled (N = 13)
Male tickler/Male tickled (N = 15)

This division allowed for a two-way analysis of variance (ANOVA) to assess the effect of both the tickler’s and the tickled individual’s gender on dependent variables such as laughter and involuntary muscle contractions (IMC).

In the study “The importance of skin area and gender in ticklishness“, it was found that laughter was more frequent in female subjects, regardless of the tickler’s gender. The subjective sensation of ticklishness and IMC scores were higher in opposite-gender pairings.

Which body areas are most sensitive to tickling?

The areas most prone to ticklishness included:

Ankles
Knees
Medial sides of the thighs and legs
Lateral sides of the upper body
Elbows
Upper arms
Neck and shoulders

What is the relationship between skin area, gender, and social and biological responses?

It was hypothesized that laughter in response to tickling stimulation could express gender stereotypes in socio-expressive behavior within playful social interactions, whereas IMC and the subjective ticklishness sensation might reflect biological components of playfulness in opposite-gender pairings when tickled with a feather.

The study used feather stimulation over a large skin area and challenged the idea that light tickling (knismesis) is incapable of eliciting reflexive behavior by examining the effect of gender on local involuntary muscle contractions (IMC). A distinction was made between social responses (laughter) and biological responses (IMC), as well as the subjective experience of ticklish areas.

What does laughter from tickling express, according to the study?

According to the study, laughter in response to tickling stimulation could reflect gender-based stereotypes of socio-expressive behavior in playful social interactions.

Other key findings on laughter include:

Laughter was more frequent in female subjects, regardless of the tickler’s gender.
A distinction was made between social responses (laughter) and biological responses (involuntary muscle contractions) to tickling.
It was hypothesized that females would score significantly higher than males in laughter due to sociocultural gender differences in emotional expressiveness across most societies.
Results showed that females scored significantly higher for laughter in both supine and prone positions.
Laughter was associated with frequent involuntary muscle contractions in both positions.
Laughter seemed to invite playful interaction.
The study did not investigate humor as a social phenomenon or participants’ individual sense of humor.
The quality of laughter was not assessed.
Females were more likely than males to respond openly with laughter, regardless of the tickler’s gender.

What are the limitations of the study?

The main limitations of the study on ticklishness sensitivity concern the assessment method and the generalizability of the findings.

Key limitations include:

The method for evaluating responses may have missed important information, as facial expressiveness was not recorded. A setup where the face was visible during tickling might have led to different conclusions.
The quality of laughter was not assessed, meaning that a strong exhalation without vocalization would not have been counted, potentially limiting the number of recorded laughter responses.
The study did not measure participants’ playful state via post-session questionnaires, due to the challenge of validating and establishing state playfulness metrics.
The duration of tickling stimulation was not standardized, resulting in variations that required statistical control. Notably, tickling lasted significantly longer when the tickler was female.
The subjects were all university students, which may limit the generalizability of the results to other age groups or populations.
The study focused on light tickling (knismesis) and may not be directly comparable to studies using more intense stimulation (gargalesis).
The study did not investigate humor as a social phenomenon or participants’ individual sense of humor.
The most ticklish areas might vary depending on the type of stimulation used.
