INTRODUCTION
Meaning of APPROACHES:
 A way of dealing with a situation or problem.
 An approach in studying child development is important
as it helps to understand the way the child behaves in
different age group.
Approaches
CROSS - SECTIONAL APPROACH
CROSS - CULTURAL APPROACH
LONGITUDINAL APPROACH
Cross sectional approach
 Cross-sectional research studies are based on
observations that take place in different groups at one time.
 A cross section means “a typical or representative
sample of a large group”.
 Cross-sectional research involves using different groups of
people who differ in the variable of interest but share other
characteristics, such as socioeconomic status, educational
background, and ethnicity.
Meaning and Definition
 Cross-sectional method examines several groups
of people at one point in time.
 For example, if you investigated changes in social
behaviour in 20-, 30-, and 40-year olds all
measured at one point in time, you would be
conducting a cross-sectional research study.
 The cross sectional method of investigation often
is used when the research aim is to compare
developmental levels at various ages or
backgrounds.
 Many children at different ages are studied in groups in according to their
age, and the results on the same sets of measures are compared for the
group.
 Example, the approximate age at which an infant can be expected to roll
over, creep, crawl, pull himself up to a standing position, and walk unaided
can be determined by observing the behavior of groups of children from
birth until the age of about 15 months.
 If the investigator, study a group of one month old infants, another group of
two month olds, and a different group of babies at every month of age
thereafter, we will have a cross sectional approach.
Characteristics :
 People are studied at a “point” in time, without follow up.
 Variables are not manipulated by researchers
 Provide information only; do not answer why
 Cross-sectional studies include surveys
 Allows teachers to look at numerous things
at once (age, income, gender)
 In psychology, cross-sectional research studies
are often used by researchers studying
developmental psychology.
 They often do this to examine changes in similar
groups at different ages.
 However, a cross-sectional study may also
compare groups from different backgrounds.
 A cross sectional study may also compare
people from different backgrounds.
Uses
Advantages/Merits
 Using a cross-sectional design has one advantage in that a study can be
conducted in a shorter amount of time as opposed to waiting for a group of
5 year olds to reach the age of 15 and observe the changes in social behavior
over the course of 10 years
 A cross-sectional study may also compare people from different backgrounds.
 Cross-sectional studies help us to identify the age-demarcated transitions
during which one or more changes take place, and individual differences in
the ages at which an ability is acquired.
 Efficient, large numbers of subjects
 Can measure attitudes, beliefs, behaviors, personal or family
history, genetic factors, existing or past health conditions, or
anything else that does not require follow-up to assess.
 Easy and quick
 Less expensive
 Can target a larger sample size
Limitations/ Demerits / Disadvantages
 Differences do not necessarily reflect individual’s development
 Differences between age groups reveal just that – differences – and not the process of
developmental change within the child.
 Information on individual change is not available
 Risk of no-response
 Cannot be used to analysed behaviour over a period to time.
 Does not help determine cause and effect.
Cross Cultural Approach
Meaning:
 The study of the relationship between cultural
context and human behaviour.
 This approach comparing two or more cultures and
understanding their values, beliefs and norms.
 Dealing with or offering comparison between two or
more different cultures or cultural areas.
 People differ culturally to the extent that their customs,
roles and other learned behaviours that are passed on
from generation to generation are different.
Merits or advantages
 The advantage of the cross-cultural approach as compared with the single
cultural research approach is that the possibilities for misinterpretation are less
with the former.
 It permits generalization to other societies or cultures or subcultures of the
same nation
 Confirming and exploring the university of some relationship or attribute of
social man
 It maximize the amount or range of variation.
 Natural experiments, in which regions differ In some
environmental factor which can be studied using an
experimental treatment
 Maximum variability studies.
 It helps in inter-cultural awareness.
Limitations/ Demerits / Disadvantages
 Cultural variations
 Order of needs does not always hold true for other cultures
 Biased response/risk of no-response
 Expensive as compared to cross sectional study
 Interpretation may vary from person to person
 The studies might be unsuccessfully, the researcher
could be stuck.
 Time consuming.
 It is difficult to reach a conclusion.
Longitudinal Approach
Meaning:
 A longitudinal study is an observational research method in which data is gathered for
the same subjects repeatedly over a period of time. Longitudinal research projects can
extend over years or even decades.
 Is a research in which a researcher measures a particular group of people for a long
period of time.
 In this research method, many observation are being conducted over long periods of
time on the same group or number of people.
 Example –
A group of new-born babies who were available for month-by-month measurements,
one can complete the study with repeated observations.
Characteristics :
 Longer duration
 Specific individual development can be
studied
 Include surveys
 expensive
Merits or advantages
 Specific development pattern of individual can be studies and compared .
 Variation in development among individuals within the sample can be studied – since it tracks
the performance of each person over time, research can identify common patterns as well as
individual differences in development.
 This studies permit investigators to examine relationships between early and later events and
behaviours.
 Effective in doing research on developmental trends.
 They are more powerful than cross sectional studies.
 They are highly flexible.
 They can provide high accuracy when observing changes.
Limitations/ Demerits / Disadvantages
 Long period
 Time consuming
 More expensive
 Difficulty in maintaining data
 Risk of sample size reducing due to change in place etc.
 Cannot be repeated because of practical constraints.
