Discriminated avoidance and the partial reinforcement effect

Partial reinforcement of avoidance and resistance to extinction in humans.

In anxiety, maladaptive avoidance behavior provides for near-perfect controllability of potential threat. There has been little laboratory-based treatment research conducted on controllability as a contributing factor in the transition from adaptive to maladaptive avoidance. Here, we investigated for the first time whether partial reinforcement rate, or the reliability of avoidance at controlli...

The partial reinforcement effect sustained through blocks of continuous reinforcement.

Obstacle Avoidance through Reinforcement Learning

A method is described for generating plan-like, reflexive, obstacle avoidance behaviour in a mobile robot. The experiments reported here use a simulated vehicle with a primitive range sensor. Avoidance behaviour is encoded as a set of continuous functions of the perceptual input space. These functions are stored using CMACs and trained by a variant of Barto and Sutton's adaptive critic algorith...

Partial Matchings and Pattern Avoidance

A partition of a finite set all of whose blocks have size one or two is called a partial matching. Here, we enumerate classes of partial matchings characterized by the avoidance of a single pattern, specializing a natural notion of partition containment that has been introduced by Sagan. Let vn(τ) denote the number of partial matchings of size n which avoid the pattern τ . Among our results, we...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
