Summary
Perception links fleeting sensations to environmental causes by forming associations. Contextual information transforms sensory signals into scene-based representations, crucial for understanding our environment.
Area of Science:
- Neuroscience
- Cognitive Science
- Sensory Processing
Background:
- Perception involves linking transient sensory input to environmental causes, requiring associations over space and time.
- These associations provide essential context to resolve the inherent ambiguity of sensory information.
- Previous research has begun exploring the neural mechanisms underlying contextual influences on perception.
Purpose of the Study:
- To investigate the neuronal bases of contextual influences on perception.
- To understand how the brain utilizes context to interpret sensory events.
- To elucidate the cellular processes involved in learning associations and memory retrieval's impact on sensory processing.
Main Methods:
- Review of recent studies on neuronal bases of contextual influences on perception.
- Analysis of how brain systems convert sensory codes based on contextual information.
- Examination of cellular mechanisms for association learning and memory retrieval in perception.
Main Results:
- Identified brain systems that convert neuronal codes for sensory events into perceptual representations using context.
- Demonstrated that context transforms sensory-based signals into scene-based representations.
- Shed light on cellular processes of association learning and memory retrieval's role in sensory processing.
Conclusions:
- Perception is a critical neuronal computation transforming sensory input via contextual information.
- Contextual associations are fundamental for resolving sensory ambiguity and creating coherent perceptual experiences.
- Understanding these processes reveals how the brain constructs our experience of the world.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

52.3K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...
