Sample Psychology Paper on Psychological Tests

Psychological tests are instruments used to quantify the abilities, problems, and psychophysical behavior of individuals and assist in making predictions on their psychological performance. Psychological tests can evaluate the current vocational and academic skills of an individual (achievement test), future behavior (aptitude tests), or personality traits (personality test). Psychological tests have pointed out to be effective, especially in selecting employees in government and private organizations. Some of the most helpful psychological tests include the Strong Interest Inventory (SII), Wechsler Adult Intelligence Scale (WAIS-IV), and the Wide Range Achievement Test (WRAT).

WAIS-IV is mostly used to tests intelligence in adults and adolescents above 16 years. WAIS-IV provides four index scores, which include perceptual reasoning, working memory, verbal comprehension, and processing speed (Girard et al., 2015). Subtests for each of the four index tests are compiled to give full-scale IQ. The full-scale IQ determines the ability of an individual to think and act rationally and interacts effectively with the environment.

WAIS-IV is mostly used by neuropsychologists to assess the actual level of cognitive functioning of an individual. For instance, a digit span is used on many patients to establish attentional difficulties (Girard et al., 2015). For patients with brain injury as a result of an accident, WAIS-IV is useful in determining cognitive abilities that are present or absent and hence come up with appropriate psychological interventions for healing.

In the case of an adult with attention-deficit /hyperactivity disorder (ADHD), WAIS-IV is useful in determining their intelligence assessment. This is because WAIS-IV investigates performance and verbal skills to determine the intelligence of a person on general knowledge, arithmetic, completion of pictures, and vocabulary (Girard et al., 2015). The results obtained can assist teachers and lecturers on the best intervention to assist such individuals.

On the other hand, WRAT is performed to find out if a more comprehensive intervention on a particular skill is needed. It focuses on spelling, arithmetic, and reading and can be administered to any person within 5 to 75 years for 30 minutes (Wilkinson & Robertson, 2016). The test is performed and interpreted by a professional examiner.

WRAT can be performed for students or persons with autism. In this case, skill in reading or calculations is administered to an individual and follow up carried out to determine if such skills have been acquired (Wilkinson & Robertson, 2016). A poor performance in WRAT means a more comprehensive intervention is required for an individual. In such a case, WRAT is effective as it measures the extent to which a certain skill is acquired and thus helps instructors to establish the proper techniques to assist such a person academically.

SII test gives insights on the interests of individuals to make it easier for them to pick a carrier choice that matches their interests. SII has 291 items in six main areas whose scores are displayed by Holland Codes realistic, artistic, conventional, enterprising, social, and investigative (Wilkinson & Robertson, 2016). It is a carrier assessing tool and mostly finds application in the carrier guidance sector.

SII helps choose a course or a major in college and university. In this case, SII is administered to determine the strength of a person in the six Holland Codes (Wilkinson & Robertson, 2016). Such scores determine the strength and interest of a person, therefore, assist in choosing a carrier path that fits well with their academic qualifications.

Psychological tests have proved to be effective in many fields. WAIS-IV tests are effective in determining the cognitive functioning of a person. On the other hand, WRAT is used to check if an individual has mastered an acquired skill. Finally, SII is used to establish the strengths and interests of a person to find the best carrier path.
