Statistical Assessment of Mediational Effects for Non-Linear Mediational Models

Elucidating causal relationship among variables of interests is critical to epidemiological studies. Such studies often involve mediational models, and require appropriate statistical assessment of mediational effects. However, the current statistical methodologies used to assess mediational effect are limited to linear association. Here, we propose a new definition of mediational effects for a...

Planning Models for Two-Way Avoidance and Reversal Learning ?

Reinforcement learning models can explain various aspects of two-way avoidance learning but do not provide a rationale for the relationship found between the dynamics of initial learning and those of reversal learning. Artificial Intelligence planning offers a novel way to conceptualize the learners’ cognitive processes by providing an explicit representation of and reasoning about internal pro...

Reversals Prior to Solution in Concept Identification.

These studies investigated the effects of reversal and nonreversal shifts before solution upon performance in a later concept identification task. In 2 experiments, a reversal or a nonreversal shift after an error on a critical trial had no interfering effect upon subsequent learning. The reversal and nonreversal groups made about the same number of errors and required as many trials to learn a...
