Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.4K
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...

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

1.5K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Avoidance Learning and Learned Helplessness

2.6K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

What is Natural Selection?01:32

What is Natural Selection?

129.8K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.0K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

This summary is machine-generated.

Pigeons trained on a visual task learned to selectively attend to one new dimension at each stage. This demonstrates optimized attentional dynamics in animal learning.

Area of Science:

  • Animal behavior
  • Cognitive science
  • Visual perception

Background:

  • Selective attention is crucial for efficient information processing.
  • Understanding attentional dynamics in non-human animals provides insights into general principles of cognition.
  • Pigeons (Columba livia) are established models for studying visual learning and attention.

Purpose of the Study:

  • To document the dynamics of selective attention in pigeons during a visual discrimination task.
  • To investigate how pigeons adjust their attentional focus as task complexity increases.
  • To determine if pigeons optimize their attentional strategies in a stagewise learning paradigm.

Main Methods:

  • Eight pigeons were trained on a go/no-go visual discrimination task.
  • Compound stimuli (S+ and S-) were created varying across four dimensions: shape, size, line orientation, and brightness.
  • Task complexity was increased stepwise by introducing stimuli that shared increasing numbers of dimensional values with the S+.

Main Results:

  • Pigeons initially attended to only one dimension to solve the discrimination.
  • In subsequent stages, pigeons progressively attended to one additional dimension.
  • All pigeons learned to discriminate the dimensions in a consistent order: brightness, line orientation, size, and shape.
  • This order correlated with the inherent discriminability of the dimensional values.

Conclusions:

  • Pigeons demonstrated optimized attentional behavior by selectively processing only one new dimension per learning stage.
  • The observed order of dimensional attention suggests a strategy based on perceptual discriminability.
  • These findings highlight the efficiency and adaptability of attentional mechanisms in pigeons.
