Block 4 Unit 1 Introduction to Projective Techniques and Neuropsychological Tests

1) Define projective tests. What is projective testing?

Projective tests are indirect and unstructured methods of investigation, designed to reveal information about someone's personality. They present ambiguous stimuli to which a person responds freely, and it is believed that these responses reflect the individual's internal needs, emotions, past experiences, thought processes, and relational patterns. Projective testing aims to describe and characterise personality.

2) What are the characteristic features of a projective test? 

Characteristic features of projective tests include:

• They use ambiguous and malleable stimuli that can be interpreted in many different ways.
• They allow for unrestricted responses.
• They seek to reveal unconscious or conscious needs, interests, dynamics and motivations.
• They are designed to elicit a person's characteristic modes of behaviour by observing their responses to a situation that doesn't compel a particular response.
• They are often used to gain supplementary insights into personality.
• They can be challenging to score and interpret.

3) What are the five categories of projective tests? 

Five categories of projective techniques are:

• Association techniques: where the subject responds to a stimulus with the first thing that comes to mind (e.g., word association).
• Construction techniques: where the subject creates a story or picture from a given stimulus (e.g., Thematic Apperception Test).
• Completion techniques: where the subject responds to a partial stimulus (e.g., sentence completion).
• Ordering techniques: where the subject is asked to order or rank a set of stimuli.
• Expressive techniques: where the subject engages in a creative activity like drawing or role-playing.

4) What are the basic assumptions underlying projective tests?

Basic assumptions underlying projective tests include:

• Responses to ambiguous stimuli are not random but reflect an individual's personality and psychological functioning.
• Individuals project their own unconscious needs, conflicts, and experiences onto the ambiguous stimuli.
• The way a person perceives and organises the stimulus material reveals aspects of their personality.
• These tests can access a variety of rich conscious and unconscious material.

5) Discuss in brief the major projective tests used in clinical psychology? 

Major projective tests used in clinical psychology include:

• The Rorschach Test: This involves the interpretation of responses to 10 symmetrical inkblots. The test is scored based on location, content, determinants, and popular responses.
• The Thematic Apperception Test (TAT): This test uses a series of ambiguous pictures. Individuals are asked to create stories about the pictures, which are then analysed.
• Projective Drawings: This involves having individuals create drawings (e.g., Draw-A-Person).
• Incomplete Sentences: This includes sentence completion tests.

6) What is neuropsychological assessment? 

Neuropsychological assessment is a process used to evaluate the complex psychological effects of organic brain injury, including intellectual, affective, and behavioural disturbances. It examines a range of cognitive functions such as attention, concentration, memory, reasoning, and language. It can involve systematic collection of information from the patient or others concerning factors that may influence its occurrence. It is not just a form of cognitive assessment, but can often be multidimensional.

7) Discuss the purpose and dimensions of neuropsychological assessment? 

Purposes and dimensions of neuropsychological assessment include:

• Differential diagnosis: Determining if problems arise from organic injury or other factors like mood disorders.
• Prediction of consequences: Assessing the likely effects of neurosurgical procedures.
• Evaluation of intellectual functioning: Assessing through formal pen and paper tests.
• Behavioural and emotional disturbance: Assessing through information from the patient or others.
• Descriptive assessments: Determining if a brain injury has resulted in impairment.
• Predictive assessments: Predicting likely sequelae of brain damage in specific areas.
• Tracking changes over time: Evaluating how cognitive function may change over time.
• Guiding interventions and rehabilitation: Providing guidelines for rehabilitation, vocational planning and education.

8) Briefly describe some of the widely used neuropsychological tests? 

Widely used neuropsychological tests include:

• Halstead-Reitan Battery: A comprehensive test battery consisting of 12 separate tests to assess memory, sensory-perceptual skills and problem solving.
• Luria-Nebraska Battery: A test with 11 subtests and 269 separate tasks that assess reading, writing, memory and speech.
• Wechsler Memory Scale-III: A test of memory function.
• Benton Visual Retention Test: A test of visual memory.
• Wisconsin Card Sorting Test: A test of abstract reasoning and executive function.
• Delis Kaplan Executive Function System (D-KEFS): A test to assess executive functioning (higher level thinking).
• WAIS-R as a Neuropsychological Instrument: The Wechsler Adult Intelligence Scale-Revised used as a neuropsychological instrument.
• WISC-III as a Process Instrument: The Wechsler Intelligence Scale for Children-Third edition used as a process instrument.
• Kaufman Short Neuropsychological Assessment Procedure (K-SNAP): A short neuropsychological test.
• California Verbal Learning Test: A test to assess verbal learning and memory.

9) Why use batteries like the Halstead-Reitan when brain functioning can now be assessed through a number of medical procedures? 

Reasons to use test batteries like the Halstead-Reitan despite medical procedures:

• Not all changes associated with brain injury are reflected in changed test performance: Neuropsychological tests can detect subtle cognitive and behavioural changes that may not be visible on medical scans.
• Test findings do not automatically indicate the reason for the specific performance: Neuropsychological tests can be used to determine if changes in functioning are due to brain dysfunction, or other factors such as psychiatric conditions.
• Neuropsychological test batteries are more comprehensive: They provide a detailed assessment of various cognitive functions, which is not always possible with medical procedures alone.
• Repeated testing: Neuropsychological tests can track changes in cognitive function over time, which can be useful for monitoring recovery or disease progression.
• A patient's performance is influenced not just by brain dysfunction: Other factors such as age, and education can be accounted for in neuropsychological assessment.
• Test batteries help in developing appropriate interventions: Neuropsychological testing is a valuable tool in the development of appropriate interventions or environmental adaptations
