Table 1 Systems Factorial Technology (SFT)-related theoretical glossary

From: A new measure of group decision-making efficiency

Assessment function

Assessment function of workload capacity combines both accuracy and response time (RT) into analysis. It can be used to infer the processing efficiency of four response conditions: (a) correct and fast, (b) correct and slow, (c) fast and incorrect, and (d) incorrect and slow

Coactive models

A parallel architecture which assumes that inputs from parallel channels are combined into a common accumulator. A decision is made when the total activation reaches the decision criterion

Detection sensitivity

A maximum slope of the psychometric function. The steeper the slope, the higher the detection sensitivity

Race-model inequality

The race models assume that two decision units are racing to reach a decision criterion. If race models hold, the survivor function for the collaborative condition is bounded below by a combination of survivor functions from the two non-collaborative individual conditions. Violation of this bound implies that two decision units may interact with each other with supercapacity processing; that is collective benefit

Statistical facilitation

The RT or accuracy gain produced by the standard parallel model

Stopping rules

Rules to determine when a system stops processing, special cases of interest are self-termination and exhaustive rules

Systems Factorial Technology

A theory-driven methodology that emphasizes identification of organization of processes through manipulation of experimental factors, typically under the assumption of factorial selectivity

Unlimited-capacity, independent parallel model

An architecture which assumes that each decision unit in a system work in parallel. The efficiency of the system does not change as the number of decision units increases

Workload capacity

A theoretical construct pertaining to influences on processing speed performance when the number of decision units of a system (i.e., the number of decision-maker in the present context) is varied
