The Phantom Decoy Effect in Perceptual Decision-making 1 RUNNING HEAD: The Phantom Decoy Effect in Perceptual Decision-making The Phantom Decoy Effect in Perceptual Decision-making
A phantom decoy is an alternative that is superior to another “target” option, but is unavailable at the time of choice. In value-based decisions involving phantom decoys (e.g., consumer choices), individuals often show increased preference for the similar, inferior target option over a non-dominated competitor alternative. Unlike value-based decisions that are driven by subjective goals, perce...
متن کاملOscillatory Network Dynamics in Perceptual Decision-Making
Synchronized oscillations of ensembles of neurons in the brain underlie human cognition and behaviors. Neuronal network oscillations can be described by the physics of coupled dynamical systems. This dissertation examines the dynamic network activities in two distinct neurocognitive networks, the salience network (SN) and the ventral temporal cortex-dorsolateral prefrontal cortex (VTC-DLPFC) ne...
متن کاملMemory Processes in Perceptual Decision Making
In a decision making task repeated encounters of a visual stimulus attribute to improved performance in identification and classification of that stimulus. This process is termed as repetition priming. Recent studies have proposed that response learning (RL), where previous decision gets associated with that item, accounts for a significant portion of performance gains observed in repetition pr...
متن کاملAdaptive criterion setting in perceptual decision making.
Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new reinforcement contingency resulted in a biphasic...
متن کاملMoving forward in perceptual decision making.
Imagine driving along a busy street in the dim light of a rainy evening. Suddenly, you see from the corner of your eye a dark object moving toward you from the right. Due to the poor light and rain, it is hard to decide what this object is and where exactly it is moving. However, you will have to make a decision to know whether you should swerve, hit the brakes, or just keep driving. Howmuch in...
