DRAW A PERSON TEST UNIVERSITY OF LIMPOPO, DEPARTMENT OF PSYCHOLOGY ABSTRACT This study was conducted on the basis of understanding the Draw A Person test as a psychometric tool. It includes a brief historical back, description, application and a discussion of different studies about the controversies of the validity and reliability of the test. ElMON M.

DRAW A PERSON TEST (PSYCHOMETRICS TEST) 1 UNIVERSITY OF LIMPOPO, DEPARTMENT OF PSYCHOLOGY, MPANGANE E 2015, 1 1. INTRODUCTION Draw a Person test is a human figure drawing tests which is meant to be administered to children, and adolescents however at some point it is administered to adults. The aim of the test is to assess how the child perceives the people around them including the family and other psychological activities on, interpersonal and cognitive setting. This study focuses on the use of DAP and its validity. However other topics to be covered include; historical background and description of the instrument. 2. HISTORICAL BACKGROUND The Draw a Person test (DAP) was evolved from 1948 authored by Karen Machover. According to Bond, Southers and Sproul (2015), the DAP test was developed with an aim to supplement Stanford Binet intelligence tests, with a non-verbal test. However later on it was found that the details which were contained in the drawing of person were more useful, therefore the first assessment tool through drawing was made by Florence Goodenough in 1926 and it was introduced as Draw a Man test (Jolly, 2010). 3. DESCRIPTION OF THE TEST DAP is a projective test, that allow an examinee to respond to questions through drawings. Projective tests can be applied in various settings from schools, corporate, and private practices to assess different psychological aspects include: personality, family background, intelligence, physical and emotional abuse, depression etc. Fan (2012), 1 Mpangane E is a very motivated Honors Psychology student enrolling at University of Limpopo. He holds a BA degree and wishes to enroll for Masters Clinical Psychology in the nearest future. His future research will be based on African psychology (Indigenous Knowledge System).

DRAW A PERSON TEST (PSYCHOMETRICS TEST) 2 UNIVERSITY OF LIMPOPO, DEPARTMENT OF PSYCHOLOGY, MPANGANE E 2015, asserts that this test is more appropriate when administered to children in grade one and grade two. The tests is used to understand the interaction within the members of the family and the perception of the patient over their family and the cognitive functioning of the test taker. Usually clinicians find these tests to be easily administered, and the common instruction of the test is structured as “draw a person doing something”. More over the test is timed to a maximum of 5 minutes per picture and it is advised that if the child doesn’t complete each picture on time the clinician should give instruction to the examinee to continue draw the other picture (Nagleria et al, 1991). 4. TEST APPLICATION Ozer (2010), claims that there are two main context where the human figure drawings can be put to used, this included; prediction of children intellectual development and to evaluate the emotions of the child. However Nagleria, McNeish, and Bardo, (1991), argues that this test can be used for screening on children to identify aspects like emotional and behavioral problems. Furthermore in an educational settings, this test can be used as a portion of the regular psychoeducational assessment. All the drawings are assumed to have a different meaning about the examinee and the person being drawn (Yong, 2015). Many psychologists and researchers rely on drawing tests because they believe that the drawings represents the child expression of thoughts, and because it works on their advantage since the child perceive the act of drawing as fun. However Kniel and Kniel (2008), used the DAP to measure intelligence amongst children, and a conclusion was made that the “…changes in the child’s drawings of a man or a woman represent the development of cognitive complexity or intellectual maturity...” (p9).
Explanation:
Phase simply means an angular term which represents situation of a particle in SHM at a certain instant
Let one SHM is x
1
=Asinωt and another SHM which is differ by first SHM of phase angle ϕ then other SHM is,
x
2
=Asin(ωt+ϕ)
Clear that phase of oscillation is state of oscillation of particle performing SHM.
