set.staircase: Set Up Staircase Parameters

In ccamp83/mu: R package for general statistical analysis of univariate and multivariate data

Set Up Staircase Parameters

Description

Creates a staircase configuration for psychophysical testing procedures. This function sets up the parameters for an adaptive staircase method, including starting value and step sizes for both upward and downward adjustments.

Usage

set.staircase(
  startValue,
  down.steps,
  down.delta,
  up.steps,
  up.delta,
  direction
)

Arguments

startValue	Numeric value indicating the initial stimulus intensity level
down.steps	Numeric value specifying the number of correct responses needed for a downward step
down.delta	Numeric value specifying the size of downward steps
up.steps	Numeric value specifying the number of incorrect responses needed for an upward step
up.delta	Numeric value specifying the size of upward steps
direction	Character string indicating the initial direction of the staircase ("up" or "down")

Value

A list containing the staircase configuration with components:

startValue	The initial stimulus intensity
down.param	Vector containing steps and delta for downward adjustments
up.param	Vector containing steps and delta for upward adjustments
direction	Initial direction of the staircase

Examples

# Create a basic staircase configuration
staircase <- set.staircase(
  startValue = 10,
  down.steps = 2,
  down.delta = 1,
  up.steps = 1,
  up.delta = 1,
  direction = "down"
)
