Stereotypes, Prejudice, and Discrimination
0 Views •
2020
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

This manuscript describes a protocol to examine the olfactory system of rodents. The olfactory habituation/dishabituation test will allow investigators to determine whether a mouse habituates to a repeatedly presented odor and whether the mouse demonstrates dishabituation when presented a novel odor.

Price Discrimination under Monopoly

2024
Price discrimination under monopoly refers to the practice where a monopolist charges different prices for the same product or service to different customers or in different markets. This strategy allows the monopolist to capture more consumer surplus, turning it into additional profits. For price discrimination to be effective, three conditions must be met: 1) the firm must have market power, 2) the firm must have the ability to separate markets or customers, and 3) the firm faces different...

Molecular Shape and Polarity

Dipole Moment of a Molecule Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other atom with a partial negative charge (δ–), as the electrons are pulled toward the more electronegative atom. This separation of charge gives rise to a bond dipole moment. The magnitude of a bond dipole moment is represented by the Greek letter mu (µ) and is given by the formula shown here, where Q is the magnitude of the...

This work describes a protocol for quantifying craniofacial cartilage shape using free software (tpsDigs2, MorphoJ, and PAST) to measure changes in facial structure in zebrafish larvae.
FAQs
These visual features provide separate sources of information for comparing forms. Contours and edges describe boundaries, while orientation and size help distinguish how those boundaries are positioned and scaled. Spatial arrangement adds information about relationships among parts. By varying these features, psychologists can examine which differences people detect readily and which require more detailed visual comparison.
A comparison can involve more than noticing physical differences in the immediate image. The visual system can relate an observed form to stored perceptual representations, meaning previously organized knowledge of patterns or objects. Studying this relationship helps researchers connect basic visual analysis with object recognition and determine how perception supports identifying matching or altered forms.
Shape discrimination provides a way to examine how visual attention and experience influence perceptual judgments across development. Tasks can reveal whether people focus on relevant features, learn to distinguish similar patterns, or show changing abilities as cognitive processing develops. This makes the topic useful for linking sensory organization with broader psychological processes rather than treating perception as isolated from cognition.
A basic task presents forms that participants must compare, then requires them to identify matching shapes or detect subtle differences. Researchers can manipulate contours, edges, orientation, size, or spatial arrangement to specify the comparison being tested. Responses provide evidence about which visual distinctions participants can perceive and how the selected features affect the comparison.
These studies can show how effectively participants distinguish forms that differ in particular visual features. The resulting patterns of performance help researchers evaluate visual perception, attention, learning, and the organization of sensory information. Comparisons across groups or developmental stages can also indicate perceptual changes associated with cognitive development, neurological conditions, or altered sensory processing.
Recognizing an object depends partly on organizing its visual form and comparing that information with perceptual representations. Shape discrimination tasks offer a focused way to study this process while also examining changes in visual processing. In psychology, researchers can use the findings to inform theories of object recognition and characterize perceptual differences linked to neurological conditions or altered sensory processing.
