Behavioral observations in autism research – mothers of high-risk children use more gestures

Aug 6, 2013 11:11:00 AM

Autism, language and gestures
Children with autism spectrum disorder (ASD) often have delayed development in communication and language. This impaired development can be present even in the first year of their lives. The use of gestures, like pointing and nodding, is very important in communication. Impairments in the use of those gestures goes hand-in-hand with impairments in language development. This is seen in young children with ASD. But such deficits are also more common in infants and toddlers that have a higher risk on autism (HRA), because they have an older brother or sister that was diagnosed with ASD.

Early Infant behavior development of hand preference

Apr 18, 2013 9:34:00 AM

Why measure handedness
There are many reasons to study the development of hand preference in infants. For one thing, being left-handed can be an advantage in one-on-one sports such as tennis. For example, Rafael Nadal is a left-handed player and with this natural advantage, he is now a star tennis player with many successful matches to his name. The advantage being, in a population with a left-handed minority and a right-handed majority, the left-handed Rafael Nadal plays most of his matches against right-handed opponents and is therefore well-practiced at dealing with this asymmetry. A right-hander plays the majority of his matches against other right-handers. In conclusion, when confronted with left-handers, they are less practiced, thereby giving the lefty a natural advantage.

Top 5 Consumer behavior research on the Behavioral Research Blog

Apr 12, 2013 9:23:00 AM

Observational research is becoming more and more popular in consumer science and market research. From on-site behavioral observations in supermarkets to advanced multimodal lab studies, researchers are more and more familiar with measuring and observing participant behavior. Researchers combine for example the measurement of behavioral and physiological data in order to get a more complete picture of the person’s response.

This Behavioral Research Blog post features the top 5 blog posts about consumer science, market research, and neuromarketing that were published in recent months.

Parent – child interaction – research in a lab and on-site

Jan 28, 2013 2:10:00 PM

Early in life, children are not capable of filling out a complete questionnaire or talking to an interviewer. In that case, observing behavior can provide valuable information in combination with parental interviews.

Three examples of autism research studies

Nov 29, 2012 10:33:00 AM

Knowledge is the key to developing a better understanding of autism.

Researchers often observe and code behavior in combination with other research methods such as questionnaires or parental interviews to be able to understand, recognize, and explain specific behaviors that are linked to autism.

The facial action coding system in infant behavior research

Oct 31, 2012 10:25:00 AM

Non-verbal behavior is very important in analyzing interpersonal communication. Think about waiving your arms when explaining something, nodding your head, or frowning. Facial expressions are also an essential part of non-verbal communication such as when displaying like or dislike of food. You can miss a lot of information if you don’t pay attention to non-verbal cues.

FACS
In many studies, the Facial Action Coding System (Ekman and Friesen, 1978) is used to code muscle movements in the face. It is often used in combination with another research method such as an interview or conversation analysis. How does FACS work? Movements of individual muscles are coded using Action Unit codes and the intensity is indicated on an A-B-C-D-E scale. You can code for example, inner brow raise (AU1), nose wrinkle (AU 9), and upper lip raise (AU 10). It is a long training process to get it right. Nevertheless, it has become the standard to systematically and manually code facial expressions.

How to measure infant behavior

Sep 12, 2012 11:34:00 AM

In infancy you can observe an explosive growth. Many researchers focus on this age group. Think about studies aimed at learning more about speech behavior, maternal sensitivity, or learning behavior in infancy. Would you like to learn more?

Learn more about the Early Social Communication Scales

When a baby is born prematurely, this baby and his or her parents often experience a rough start. You can think about eating problems, high risk of infection, or even anemia. Researchers focus on the differences between term and preterm infants in order to understand certain behavior, communication abilities, and learning skills so they learn more about the effects of a preterm birth. And researchers try to assess the effectiveness of interventions, such as the “Vermont Intervention Program for Low Birthweight Infants” (Rauh, 1979). By observing parent-infant interaction, researchers gain more insight in specific behaviors such as joint attention.

Examples of infant behavior research experiments

Jul 7, 2011 1:52:00 PM

In infancy you can observe an explosive growth. A lot of researchers focus on this age group and observe parent-infant dyads to get more insight in specific behaviors. Experiments are often set up to study looking behavior, language acquisition, attachment, or learning behavior.
