They also reported that the magnitude of the effect was different for different types of intelligence ("0.41, 0.30, 0.28, and 0.21 IQ points annually for fluid, spatial, full-scale, and crystallized IQ test performance, respectively"), and that the effect was stronger for adults than for children.
Cognitive epidemiology is a field of research that examines the associations between intelligence test scores (IQ scores or extracted g-factors) and health, more specifically morbidity (mental and physical) and mortality.
A Northwestern University study shows a decline in three key intelligence testing categories—a tangible example of what is called the Reverse Flynn Effect. Leading up to the 1990s, IQ scores ...
The manual includes equations for converting NART scores to predicted IQ scores on the Wechsler Adult Intelligence Scale. The NART is widely used in research settings because a measure of premorbid intelligence is rarely available. However, the Lothian Birth Cohort Study has such data. Researchers from this study demonstrated that the ...
Cubes and a target pattern used in the Wechsler Adult Intelligence Scale test. A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill. The test-taker uses hand movements to rearrange blocks that have various color patterns on ...
Patients recovering from traumatic brain injury (on average measuring in severely impaired ranged on the Glasgow Coma Scale) showed high stability in WTAR scores during their recovery period while performing highly similar to demographic estimates, suggesting the test is a reliable estimate of premorbid intelligence in individuals with TBI.

IQ tests had lower negative correlations with certain socially undesirable outcomes such as that children with high IQ were less likely to engage in juvenile crime. One example being a study finding a correlation of −0.19 (−0.17 with social class controlled for) between IQ scores and number of juvenile offenses in a large Danish sample.
The Kohs Test continues to be used in research extensively to measure executive functioning and learning, consistent with the original design of the test. [9] [10] This has made the Kohs Block Test useful for assessing the effects of aging, [11] drug use, [12] and in brain research, [13] among other areas. In particular, that the Kohs is a ...
