Decision-Making and Learning: The Peak Shift Behavioral Response
In a typical peak shift experiment, control subjects are trained to respond (e.g., button-press) to a positively reinforced stimulus (Sþ, for example a line of a particular orientation or a color of a particular hue). Treatment subjects are trained in a manner identical to control subjects with respect to Sþ and also to withhold response to an unreinforced or punished stimulus (S–, a line or hu...
متن کاملPeak shift discrimination learning as a mechanism of signal evolution.
"Peak shift" is a behavioral response bias arising from discrimination learning in which animals display a directional, but limited, preference for or avoidance of unusual stimuli. Its hypothesized evolutionary relevance has been primarily in the realm of aposematic coloration and limited sexual dimorphism. Here, we develop a novel functional approach to peak shift, based on signal detection th...

the relationship between using language learning strategies, learners’ optimism, educational status, duration of learning and demotivation
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
15 صفحه اولAn ART Neural Network Model of Discrimination Shift Learning
We present an ART-based neural network model (adapted from [2]) of the development of discrimination-shift learning that models the trial-by-trial learning process in great detail. In agreement with the results of human participants (4–20 years of age) in [1] the model revealed two distinct learning modes in the learning process: (1) a discontinuous rational learning process by means of hypothe...
