Assessment of Social Interaction Behaviors
Published on: February 25, 2011
Zygosity assessment by self-report; research reports; human interest
Summary
This review examines twins' and families' perspectives on zygosity, exploring research on the freemartin effect, mental health comparisons, and assisted reproductive technology (ART)-induced twinning. It also highlights media narratives surrounding twin experiences.
Area of Science:
- Twin Studies
- Human Genetics
- Developmental Biology
Background:
- Review of research implications and personal perspectives on twin and family self-reports of zygosity.
- Summary of recent research including potential freemartin effect in humans.
- Exploration of twin-singleton comparisons in mental health among Japanese students.
Discussion:
- Mechanisms underlying assisted reproductive technology (ART)-induced monozygotic twinning.
- Analysis of twin stories in media, such as infant revival and career decisions.
- Examination of the emotional and societal impact of twin loss.
Key Insights:
- Self-reporting of zygosity by twins and families carries significant research implications.
- ART may influence monozygotic twinning rates, requiring further investigation.
- Media portrayals of twin experiences offer insights into societal perceptions and individual narratives.
Outlook:
- Future research should focus on validating zygosity self-reports and understanding ART-induced twinning.
- Continued analysis of twin narratives in media can illuminate societal views on twinning.
- Further studies are needed on the psychological and developmental aspects of twinning.

02:30Naturalistic Observations
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
02:45The Ratio of X Chromosome to Autosomes
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female Drosophila...

01:23Behavioral Genetics and Its Designs
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.

01:19X-linked Traits
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.
