Perception, Expectation, Affect, Analysis

Affect and expectation.

4 groups of Ss were exposed to a probability learning situation in which they guessed which of 2 stimuli would next appear. One set of stimuli contained angry and smiling faces, while the other or neutral set contained big and little kangaroos. When the input ratio was 70% angry faces to 30% smiling faces, Ss markedly underestimated the dominant input. When the ratio was reversed (70% smiling, ...

Does Explicit Expectation Really Affect Preparation?

Expectation enables preparation for an upcoming event and supports performance if the anticipated situation occurs, as manifested in behavioral effects (e.g., decreased RT). However, demonstrating coincidence between expectation and preparation is not sufficient for attributing a causal role to the former. The content of explicit expectation may simply reflect the present preparation state. We ...

Expectation and the perception of color.

Repetition, expectation, and the perception of time

Prior experience with a stimulus profoundly affects how it is processed, perceived, and acted upon. One striking finding is that repeated items seem to last for less time than novel or rare ones. This link between the processing of stimulus identity and the perception of stimulus duration has important implications for theories of timing, and for broader accounts of the organization, purpose, a...

Neural Anticipative Architecture for Expectation Driven Perception

In this paper we present a biologically inspired neural architecture for visual perception based on anticipation. The main goal of this work is to demonstrate, that anticipation is a central key to improve the perception performance of technical systems. The presented approach is able to increase the robustness of the perception process against noise or sensory dropouts. We demonstrate these pe...
