Attention

Divided Attention

Attending to multiple stimuli at the same time.

Selective Attention

Attending to one stimulus while others are present.

Sustained Attention

Attending to a specific stimulus over a long period.

Executive Attention

Regulating oneself to focus on creating steps to complete one task.

Attention Span Formula

Attention Span (seconds) = Age (in years) × 2-5.

Attention Span for 4-year-old

A 4-year-old child might maintain attention for 8-20 minutes.

Attention Span for 10-year-old

A 10-year-old child might maintain attention for 20-50 minutes.

Attention Span for Adults

Adults typically have attention spans of 10-20 minutes for focused learning activities.

Factors Impacting Attention Span

Task difficulty, environmental distractions, cognitive load, mental fatigue, emotional state, sleep quality.

Visual Selective Attention

Focusing on specific visual stimuli while ignoring others in the visual field.

Auditory Selective Attention

Focusing on specific sounds or voices while filtering out background noise.

Spatial Selective Attention

Directing attention to a particular location in space.

Feature-based Selective Attention

Focusing on specific features or attributes of stimuli, such as color or shape.

Object-based Selective Attention

Attending to entire objects rather than individual features.

Temporal Selective Attention

Focusing on stimuli that occur at specific points in time.

Broadbent's Filter Theory

Proposes that information is filtered early in processing.

Treisman's Attenuation Theory

Suggests that unattended information is attenuated rather than completely filtered out.

Deutsch and Deutsch's Late Selection Theory

Argues that all stimuli are processed for meaning before selection occurs.

Cocktail Party Effect

Our ability to focus on a specific conversation in a noisy environment while ignoring others.

Key Aspect of the Cocktail Party Effect

Demonstrates selective attention to meaningful information while ignoring irrelevant stimuli.

Noticing Our Name in Noise

We are more likely to notice our name being mentioned in a conversation we're not actively listening to.

Colin Cherry's Contribution

First described the cocktail party effect in 1953 through dichotic listening experiments.

Cognitive Overload Prevention

The cocktail party effect highlights the brain's filtering capabilities to prevent overload.

Support for Treisman's Theory

The cocktail party effect supports the idea that significant stimuli can break through attentional filters.

Environmental Distractions

External factors that can divert focus and reduce attention span.

Cognitive Load

The mental effort being used in the working memory.

Mental Fatigue

A state of tiredness that can negatively affect attention span.

Emotional State

Feelings that can either enhance or hinder attention capabilities.

Sleep Quality

May impact cognitive functioning and attention span.

Attention Span Variability

Attention span varies based on motivation, interest, and individual differences.

Dichotic Listening Experiments

Research conducted to study how we process different auditory stimuli.

Irrelevant Stimuli

Non-significant information that is filtered out during the attention process.

Processing of Unattended Stimuli

Some level of processing occurs for stimuli that are not actively attended to.

Filtering Capabilities of the Brain

The brain's ability to manage and prioritize different stimuli.

Focus on Specific Sounds

Auditory selective attention allows us to concentrate on certain conversations.

Effective Learning Activities Duration

Adults usually engage in focused learning for about 10-20 minutes.

Attention Span Measurement

A formula that gives an estimate based on age and capability.

Types of Selective Attention

Includes visual, auditory, spatial, feature-based, object-based, and temporal attention.

Meaningful Information Focus

Selectively attending to information that holds personal relevance.

The Role of Motivation in Attention

Motivation can significantly impact how long one can maintain attention.

Developmental Changes in Attention Span

Attention span typically increases with age.

Strategies to Enhance Attention

Methods used to improve focus and sustain attention over longer periods.
