Measures of Intelligence01:29

Measures of Intelligence

8.4K
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;...

Guidelines For Measuring Vital Signs01:19

Guidelines For Measuring Vital Signs

2.8K
Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

Binet's Contribution to Measures of Intelligence01:23

Binet's Contribution to Measures of Intelligence

1.7K
Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...

Wechsler's Contribution to Measures of Intelligence01:23

Wechsler's Contribution to Measures of Intelligence

2.1K
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...

Language01:16

Language

898
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Signs of Puberty01:27

Signs of Puberty

1.5K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Area of Science:

  • Linguistics
  • Deaf Studies
  • Psychology

Background:

  • Intelligibility is well-researched in spoken languages but understudied in signed languages.
  • American Sign Language (ASL) intelligibility has not been previously investigated.
  • Understanding factors influencing sign language comprehension is essential.

Purpose of the Study:

  • To investigate the construct of intelligibility in American Sign Language (ASL).
  • To evaluate self-report and expert rating measures for sign intelligibility.
  • To examine frequency, amount, and ease of understanding in ASL.

Main Methods:

  • 66 college students (42 Deaf, 24 hearing) with varying ASL skills participated.
  • Participants self-rated their ASL intelligibility and provided a signed language sample.
  • Expert raters assessed language samples using intelligibility measures.

Main Results:

  • Expert ratings of ASL sign intelligibility were significantly and positively correlated across all measures.
  • Signer understanding was predicted by amount and frequency of understanding, and ASL production skills.
  • Picture comprehension was predicted by ease of understanding and ASL grammar skills.

Conclusions:

  • Sign intelligibility is a construct meriting further investigation.
  • Self- and expert ratings of ASL intelligibility showed no significant differences.
  • Self-report measures using the Intelligibility in Context Scale-ASL (ICS-ASL) were not feasible for assessing familiarity.
