Adaptable history biases in human perceptual decisions.
When making choices under conditions of perceptual uncertainty, past experience can play a vital role. However, it can also lead to biases that worsen decisions. Consistent with previous observations, we found that human choices are influenced by the success or failure of past choices even in a standard two-alternative detection task, where choice history is irrelevant. The typical bias was one...
متن کاملDebiasing context effects in strategic decisions: Playing against a consistent opponent can correct perceptual but not reinforcement biases
Vlaev and Chater (2006) demonstrated that the cooperativeness of previously seen prisoner’s dilemma games biases choices and predictions in the current game. These effects were: a) assimilation to the mean cooperativeness of the played games caused by action reinforcement, and b) perceptual contrast with the preceding games depending on the range and the rank order of their cooperativeness. We ...
متن کاملNeural Variability Quenching Predicts Individual Perceptual Abilities.
Neural activity during repeated presentations of a sensory stimulus exhibits considerable trial-by-trial variability. Previous studies have reported that trial-by-trial neural variability is reduced (quenched) by the presentation of a stimulus. However, the functional significance and behavioral relevance of variability quenching and the potential physiological mechanisms that may drive it have...
متن کاملArea of Origin, But Not Farm or Sex, Predicts Horse Carcass Weight as a Main Effect
The aim of this study was to evaluate the differences between cold carcass weights (CCW) for the Catalan Pyrenean horse (Cavall pirinenc català) breed according to different variables: area of origin, farm, gender and age. Linear regression models were applied using a generalized linear model (GLM) procedure for CCW of 397 animals (217 males and 180 females) slaughtered in a commercial abattoir...
متن کاملPrestimulus alpha-band power biases visual discrimination confidence, but not accuracy.
The magnitude of power in the alpha-band (8-13Hz) of the electroencephalogram (EEG) prior to the onset of a near threshold visual stimulus predicts performance. Together with other findings, this has been interpreted as evidence that alpha-band dynamics reflect cortical excitability. We reasoned, however, that non-specific changes in excitability would be expected to influence signal and noise ...
