Is overall similarity classification less effortful than single-dimension classification?
Summary of "Is overall similarity classification less effortful than single-dimension classification?"
It is sometimes argued that the implementation of an overall similarity classification is less effortful than the implementation of a single-dimension classification. In the current article, we argue that the evidence securely in support of this view is limited, and report additional evidence in support of the opposite proposition-overall similarity classification is more effortful than single-dimension classification. Using a match-to-standards procedure, Experiments 1A, 1B and 2 demonstrate that concurrent load reduces the prevalence of overall similarity classification, and that this effect is robust to changes in the concurrent load task employed, the level of time pressure experienced, and the short-term memory requirements of the classification task. Experiment 3 demonstrates that participants who produced overall similarity classifications from the outset have larger working memory capacities than those who produced single-dimension classifications initially, and Experiment 4 demonstrates that instructions to respond meticulously increase the prevalence of overall similarity classification.

Medical and Biotech [MESH] Definitions
Vertical Dimension
The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position. (From Jablonski, Dictionary of Dentistry, 1992, p250)
Book Classification
A general term covering bibliographical and bibliothecal classifications. It mostly refers to library CLASSIFICATION for arrangement of books and documents on the shelves. (Harrod's Librarians' Glossary, 7th ed, p85)
Alismatidae
A plant subclass of the class Liliopsida (monocotyledons) in the Chronquist classification system. This is equivalent to the Alismatales order in the APG classification system. It is a primitive group of more or less aquatic plants.
Machiavellianism
A personality dimension characterized by the manipulation of others.
Pitch Perception
A dimension of auditory sensation varying with cycles per second of the sound stimulus.
