This Perspectives is devoted to the ideas of the French zoologist Georges Teissier about the mechanisms of evolution and the relations between micro- and macroevolution. Working in an almost universally neo-Lamarckian context in France, Teissier was one of the very few Darwinians there at the time of the evolutionary synthesis. The general atmosphere of French zoology during the 1920s and the 1...

Over the past 20 years, human contingency learning has resurfaced as an important topic within experimental psychology. This renewed interest was sparked mainly by the proposal that associative models of Pavlovian conditioning might also apply to human contingency learning--a proposal that has led to many new empirical findings and theoretical developments. We provide a brief review of these re...

gestions that humane patient care may be either uninfluenced or perhaps even enhanced by scientific medicine and the accompanying new morality. However, a warning by Babbie should be emphasized: It may be that "the indicators of humane patient care used in these analyses are not adequate to the research problem." Inferences about faculty performance based on faculty views reported by and often ...

Alternating Treatments Designs (ATD) with random assignment of the treatments to the measurement times provide very powerful single-case experiments. However, complete randomization might cause too many consecutive administrations of the same treatment to occur in the design. In order to exclude these possibilities, an ATD with restricted randomization can be used. In this article we provide a ...

3 monkeys impaired on delayed response and delayed alternation after midlateral frontal lesions, 3 monkeys unimpaired on these tasks after control lesions, and 3 unoperated monkeys were tested on spatial delayed response (with direct baiting) and spatial delayed alternation following 2, 26, and 50 hr. of food deprivation. Increased deprivation improved delayed response performance by all groups...

With growing opportunities for individually motivated agents to work collaboratively to satisfy shared goals, it becomes increasingly important to design agents that can make intelligent decisions in the context of commitments to group activities. In particular, agents need to be able to reconcile their intentions to do team-related actions with other, conflicting intentions. We present the SPI...

The objective of this study was to conduct a systematic review and meta-analysis of teamwork interventions that were carried out with the purpose of improving teamwork and team performance, using controlled experimental designs. A literature search returned 16,849 unique articles. The meta-analysis was ultimately conducted on 51 articles, comprising 72 (k) unique interventions, 194 effect sizes...
