National Health Expenditure Projections, 2023-32: Payer Trends Diverge As Pandemic-Related Policies Fade.

Health care spending growth is expected to outpace that of the gross domestic product (GDP) during the coming decade, resulting in a health share of GDP that reaches 19.7 percent by 2032 (up from 17.3 percent in 2022).

Perseveration on a reversal-learning task correlates with rates of self-directed behavior in nonhuman primates.

In humans and several nonhuman animals, repetitive behavior is associated with deficits on executive function tasks involving response inhibition. We tested for this relationship in nonhuman primates by correlating rates of normative behavior to performance on a reversal-learning task in which animals were required to inhibit a previously learned rule. We focused on rates of self-directed behavior (scratch, autogroom, self touch and manipulation) because these responses are known indicators of arousal or anxiety in primates, however, we also examined rates of other categories of behavior (e.
