Children prenatally exposed to opioids exhibit impairments in cognitive functioning and have an increased likelihood of experiencing other forms of adversity. Given that these other forms of early life adversity are linked to lower levels of cognitive functioning, it is important to determine whether the association between opioid exposure and…

The majority of episodic memory (EM) tests are far removed from what we experience in daily life and from the definition of this type of memory. This study examines the developmental trajectory of the main aspects of episodic memory--what, where, and when--and of feature binding in a naturalistic virtual environment. A population of 125…

Reviews two models of thinking and intellectual development: Scandura's deterministic model of structuralistic learning, and a generalization of Rasch's probabilistic latent trait model. Models are compared by means of two experiments with balance scale tasks. (RH)

Two studies on M-capacity found factor-analytical and correlational evidence that five M-capacity tests share a common source of variance and that, as subjects' increase in age, scores increase at a similar rate. Results suggest that, in the 6-11 age range, M-capacity can be measured with a battery of tests. (AA)

Examines subjects' processing in misleading test items. Suggests that the M-power for children, when assessed behaviorally, may increase with age in a discrete manner, and have the potential to generate interval scales of measurement. In addition, suggests that, in light of the results, what statisticians often consider "error of…
