A slip is the error that occurs when a person does an action that is not intended. In this article I examine several collections of slips, primarily of actions, with the aim of devising a theoretical explication. A theory of action is outlined in which an action sequence is represented by a parent schema and numerous child schemas, in which several action schemas can be active at any one time, and in which each schema has a set of triggering conditions and an activation value. The path from…

Slip-Proof Actions

Most human actions are complex, but some of them are basic. Which are these? Here, I address the question by invoking slips, a common kind of mistake. The proposal is this: an action is basic for an

What do people think they're doing? Action identification and human behavior.

Issues in the cognitive representation and control of action are broached from the perspective of action identification theory. This theory holds that any action can be identified in many ways,

Role of the Spatial Frames of Reference in the Genesis of the Action Slips

Within the classical approach by Norman (1981); action slips are essentially due to activation and triggering of a unappropriate schema. The aim of this study was to investigate action slips starting

Formal Ontology of Action: a Unifying Approach

OntoSTIT+ is a theory which specifies the meaning of the concepts of agency and action, and facilitates meaning negotiation among agents, as long as the concept of action is taken into account.

Automatic actions: Agency, intentionality, and responsibility

Abstract This article discusses a challenge to the traditional intentional-causalist conceptions of action and intentionality as well as to our everyday and legal conceptions of responsibility,

Representing and Learning Routine Activities

This dissertation addresses the question of how an agent who is engaged in ordinary, routine activities changes its behavior over time, how the agent's internal representations about the world is affected by its interactions, and what is a good agent architecture for learning routine interactions with the world.

Order and Disorder in Everyday Action: the Roles of Contention Scheduling and Supervisory Attention

The contention scheduling/supervisory attentional system approach to action selection is described and this account is used to structure a survey of current theories of the control of action on how such theories account for the types of error produced by some patients with frontal and/or left temporoparietal damage when attempting everyday tasks.



Production Systems: Models of Control Structures

The Schema as a Solution to Some Persistent Problems in Motor Learning Theory

Simulating a Skilled Typist: A Study of Skilled Cognitive-Motor Performance

A model for the control of the hands and fingers during typing based upon an Activation-Trigger-Schema system in which a hierarchical structure of schemata directs the selection of the letters to be typed and, then, controls the hand and finger movements by a cooperative, relaxation algorithm.

A spreading-activation theory of semantic processing

The present paper shows how the extended theory can account for results of several production experiments by Loftus, Juola and Atkinson's multiple-category experiment, Conrad's sentence-verification experiments, and several categorization experiments on the effect of semantic relatedness and typicality by Holyoak and Glass, Rips, Shoben, and Smith, and Rosch.

An Interactive Activation Model of the Effect of Context in Perception. Part 2

A number of new experiments are presented, designed to assess the roles of direct and indirect evidence concerning the identity of a letter in an input string and a number of extensions of the model are proposed to account for aspects of word perception currently ignored.

Descriptions: An intermediate stage in memory retrieval

A schema theory of discrete motor skill learning.

A number of closed-loop postulations to explain motor skills learning and performance phenomena have appeared recently, but each of these views suffers from either (a) logical problems in explaining
