  10. Visual discrimination: Identifying differences or similarities between visual stimuli, showcasing attention to detail and discrimination skills.
  11. Figural series: Test-takers identify the next figure in a series based on established patterns, demonstrating pattern recognition and logical reasoning.
  12. Scoring and interpretation: Once completed, the test is scored, and the results are interpreted. Scores are often compared to a normative sample to determine how an individual's performance compares to others.

Scoring and interpreting the results

Scoring and interpreting a non-verbal intelligence test involves a multi-step process that requires specific training and expertise by someone with a professional degree, focusing on particular subgroups who may need to use this test. It cannot be accurately done without access to the specific test and the individual's raw scores as the response format can differ from test to test and critical reviews of results are often required. However, general scoring and interpretation based on a typical response format and research findings follow:

Gathering information:

  • Test administration: The first step involves ensuring the test was administered correctly according to standardized procedures and ensuring the participant understood the simple oral instructions required to complete the answer booklets accurately. This includes factors like test environment and time limits and ensuring simple oral instructions are provided for the test takers.
  • Raw scores: The examiner will record the individual's responses to each item on the test, resulting in a set of entire normative sample raw scores for each specific subgroup of questions.

Scoring the test:

  • Conversion tables: Raw scores are then converted into scaled or standard scores using tables specific to the test and the individual's age or other relevant demographics.
  • Subscores and index scores: Many non-verbal intelligence tests provide subscores in different cognitive domains, such as spatial reasoning, visual memory, and pattern recognition. These subscores can be combined to form index scores that reflect overall cognitive ability.

Interpretation of results:

  • Comparing scores to norms: Scaled scores or index scores are then compared to the entire normative sample data from a representative population sample. This comparison provides information about the individual's relative standing compared to their peers regarding non-verbal intelligence.
  • Qualitative analysis: The examiner will also analyze the individual's pattern of strengths and weaknesses across different subtests to better understand their cognitive abilities.
  • Considering context: The test results should always be interpreted in the context of the individual's background, history, and other relevant factors. A qualified professional can consider these factors to provide a comprehensive and nuanced understanding of the individual's cognitive strengths and needs.

Research findings

Research delves into the intricate connection between social group functioning, narrative skills, school success, and non-verbal intelligence in the context of early childhood development. With a mixed design approach, the research encompasses 109 children, initially identified through the sociometric method to determine their social group affiliations. Subsequently, their narrative skills were evaluated by analyzing their commentary on the picture book 'Frog Where Are You?'. The investigation also incorporated the collection of grade point average records from class record-keeping books. Noteworthy findings indicate discernible differences in school success and non-verbal IQ based on the type of social group.

The study further underscores a significant relationship between non-verbal intelligence, narrative skills, and school success, revealing that the latter is predictably influenced by both non-verbal intelligence and narrative proficiency. This research sheds light on the interconnected nature of social dynamics, cognitive abilities, and academic achievements during the formative years of a child's development (Shaqiri et al.).
