- Casual observation does little by itself to establish a strong base of knowledge. 
- Can lead people to erroneous conclusions. 

Disadvantages of Unsystematic Observation 

Unsystematic observation allows us to develop hypotheses that can eventually be tested more systematically.

The most basic and pervasive of all research methods is observation.  Experimental, case study, and naturalistic approaches all involve making observations of what someone is doing or has done.

Unsystematic Observation 

- The investigators exerts some degree of control over the events carried out in the field or relatively natural settings. 
- It provides more authentic insight into the nature of clients' emotions and behaviors. 
- It can be used to assess communication patterns between couples or spouses.

Controlled Observation 

A team of psychologists wants to study prosocial behavior in toddlers. They bring pairs of toddlers into a specially designed playroom. In the middle of the play session, a researcher 'accidentally' drops a box of pencils. The research team, observing from behind a one-way mirror, records whether the toddlers attempt to help the researcher pick up the pencils. Based on this description, identify the specific type of observational method being used and justify your answer.

Identifying Observational Research Methods

A case study is an observational research method involving an in-depth, and often longitudinal, examination of an individual, social unit, or event. In psychology, case studies typically provide a detailed qualitative description and analysis of a single individual, frequently one who has a rare condition, unusual disorder, or specific brain damage. While they primarily rely on qualitative tools like interviews and naturalistic observation, case studies can also incorporate quantitative data such as psychological testing or physiological measurements.

Case Study

Naturalistic observation is a research approach that involves observing behavior in its natural context, where it typically occurs, rather than in an artificial or controlled setting. For example, a developmental psychologist might study how children behave on a playground, at a daycare center, or in their own home, just as other researchers might observe chimpanzees in the wild or shoppers in a grocery store.
