まとめ
ウェクスラー成人知能スケール第5版 (WAIS-5) の構造は,そのマニュアルとは異なる. 独立した分析によると,フルスケールIQは主に一般的な知能 (g) を推定し,特定の認知的要因ではありません.
科学分野:
- サイコメトリクス サイコメトリクス
- 認知心理学とは,認知心理学である.
- インテリジェンステスト インテリジェンステスト
背景:
- ウェクスラー成人知能スケール第5版 (WAIS-5) は,広く使用されている知能テストです.
- テクニカルマニュアルでは,特定の潜在因数構造を提示しています.
- この構造の独立した検証は,正確な解釈に不可欠です.
研究 の 目的:
- WAIS-5の潜在因子構造を独立に評価する.
- WAIS-5マニュアルで提案された構造と実証的発見を比較する.
- WAIS-5の解釈のための根拠に基づいたガイドラインを提供すること.
主な方法:
- シュミットとライマンの手順を用いた階層的な探索的因数分析 (EFA).
- WAIS-5標準化サンプル (N = 2,020) の確認因数分析 (CFA) を実施した.
- 主要および次要WAIS-5サブテスト20件に関する記述的統計の分析.
主要な成果:
- EFAは5つの異なる潜在的要因をサポートしませんでした;視覚空間と流動的推理を統合した4つの要因モデルがサポートされました.
- この4要素モデルでは,WAIS-IV.に似た一般知能 (g) 要素が優勢でした.
- CFAは,EFAの結果と整合した4つのグループファクターを持つバイファクターモデルが最適であると確認しました.
結論:
- 経験的なWAIS-5の構造は,その技術マニュアルに記載されているモデルと一致していません.
- 発見は,Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) の以前の独立した評価を再現しています.
- フルスケールIQ (FSIQ) は,主に,サイコメトリックの一般知能 (g) の推定値として解釈されるべきである.

01:23Wechsler's Contribution to Measures of Intelligence
2.2K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

01:29Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

00:49Complementation Tests
6.3K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

14.2K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

01:29Measures of Intelligence

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
