Attention and Perception: Models, Effects, and Distractions in Psychology

What is attention?

Focusing on specific features, objects, locations, thoughts, or activities.

What does selective attention refer to?

The ability to focus on one message and ignore all others.

What is the shadowing technique in attention research?

A method where participants repeat aloud the words they hear in the attended ear during dichotic listening.

What did Colin Cherry's experiments reveal about attention?

Participants could shadow the attended message but were largely unaware of the content in the unattended ear.

What is the role of attentional capture in everyday situations?

It explains how sudden stimuli can disrupt focus and shift attention unexpectedly.

How does divided attention affect performance?

It can lead to decreased performance on tasks due to the cognitive load of managing multiple stimuli.

Donald Broadbent in 1958.

What are the stages of Broadbent's filter model of attention?

1. Sensory memory, 2. Filter, 3. Detector, 4. Short-term memory.

What does the filter in Broadbent's model do?

It identifies the attended message based on physical characteristics and lets it pass to the detector.

What is the role of the detector in Broadbent's model?

It processes the attended message to determine higher-level characteristics, such as meaning.

What is the output of the detector sent to?

Short-term memory, which holds information for 10 to 15 seconds.

What is an early selection model?

An experiment by Gray and Wedderburn where participants reported hearing 'Dear Aunt Jane' instead of the shadowed message, indicating meaning processing.

What modification did Anne Treisman propose to Broadbent's model?

She proposed the attenuation model, where an attenuator analyzes messages based on physical characteristics, language, and meaning.

What is the attenuator in Treisman's model?

A process that analyzes incoming messages and allows attended messages to pass through at full strength while attenuating unattended messages.

What does it mean for a model to be a 'leaky filter' model?

It means that some unattended information can still be processed and get through, albeit at a weaker strength.

What is the significance of Treisman's model in attention studies?

It allows for the analysis of both attended and unattended messages, acknowledging that some unattended information is processed.

How does Treisman's model differ from Broadbent's model?

Treisman's model allows for some processing of unattended messages, while Broadbent's model suggests they are completely filtered out.

What is selective attention?

The process of focusing on a specific object in the environment for a certain period of time while ignoring others.

What is sensory memory?

What is short-term memory?

A memory system that holds information for a short duration, typically 10 to 15 seconds.

What is long-term memory?

A memory system that can hold information indefinitely.

What is the significance of physical characteristics in attention models?

They are used to identify and filter messages in the early stages of processing.

What role does meaning play in Treisman's attenuation model?

Meaning can be used to separate messages when physical characteristics alone are insufficient.

What does the term 'top-down processing' refer to?

The cognitive process where perception is influenced by expectations and prior knowledge.

What is the primary focus of attention research?

Understanding how individuals selectively process information from their environment.

What are the implications of the cocktail party effect for attention?

It illustrates how individuals can focus on specific stimuli despite competing distractions.

How does the filter model explain selective attention?

By suggesting that only one message is processed at a time based on its physical characteristics.

What is Treisman's attenuation model of selective attention?

A model proposing that an attenuator filters incoming information, allowing some unattended messages to be processed based on their meaning.

What does the dictionary unit in Treisman's model do?

It contains stored words and thresholds for activating those words, helping to explain why familiar words can be heard in unattended messages.

What is a threshold in the context of Treisman's model?

The smallest signal strength that can barely be detected; words with low thresholds are easily activated even with weak signals.

How does Treisman explain the detection of a person's name in a noisy environment?

Names have low thresholds, allowing them to be detected even when presented softly or obscured by other sounds.

What is a late selection model of attention?

A model suggesting that selection of stimuli for final processing occurs after the information has been analyzed for meaning.

What experiment did Donald MacKay conduct related to late selection models?

Participants listened to ambiguous sentences while biasing words were presented to the unattended ear, affecting their interpretations.

What is priming in the context of attention?

A change in response to a stimulus caused by the previous presentation of the same or a similar stimulus.

What is repetition priming?

When an initial presentation of a stimulus affects the person's response to the same stimulus when it is presented later.

What is lexical priming?

Priming that involves the meaning of words, where related meanings can influence responses.

What did MacKay's findings suggest about unattended information?

That meaning can be processed even for words that are unattended, affecting participants' judgments.

What factors influence selective attention according to recent research?

The nature of the distracting stimulus and the characteristics of the task being performed.

What is processing capacity?

The amount of information input that a person can handle, setting limits on their ability to process information.

What is perceptual load?

Related to the difficulty of a task; it determines how much of a person's processing capacity is used.

What is a low-load task?

A task that uses few resources, leaving some capacity to handle other tasks.

What is a high-load task?

A task that uses most or all of a person's resources, leaving little capacity to handle other tasks.

How can distracting stimuli affect attention?

The ability to ignore distractions can depend on both the nature of the distracting stimulus and the task at hand.

What is the significance of the early-late selection controversy?

It highlights that both early and late selection can occur depending on the observer's task and the type of stimuli presented.

What is the role of familiar words in Treisman's model?

Familiar words, like a person's name, can be detected even in unattended messages due to their low activation thresholds.

What does Treisman's model suggest about attended and unattended messages?

It suggests that the attended message is processed fully while some parts of the unattended messages may also be processed.

What is the impact of television on eating behavior according to research?

Eating while watching television can increase the eating behavior of those watching.

What is the importance of the research on selective attention?

It defines basic phenomena of attention and conceptualizes cognition as an information processing problem.

What did the flow diagram in Treisman's model illustrate?

It illustrates how messages are processed through an attenuator and analyzed by a dictionary unit before reaching memory.

How does the concept of perceptual load relate to task performance?

Higher perceptual load tasks require more cognitive resources, making it harder to ignore distractions.

What is the relationship between task difficulty and attention?

As task difficulty increases, the capacity to handle distractions decreases, affecting attention focus.

What is the effect of biasing words in MacKay's experiment?

Biasing words influenced participants' interpretations of ambiguous sentences, even when they were unaware of those words.

What does Treisman's early selection model propose?

It proposes a filter that operates early in the information processing flow, allowing for selective attention.

What is the significance of the term 'attenuator' in Treisman's model?

The attenuator filters incoming information, determining which messages are processed based on their importance.

What are the two factors Lavie considers in her study of attention?

Processing capacity and perceptual load.

What does processing capacity refer to?

The amount of information people can handle, setting a limit on their ability to process incoming information.

What is perceptual load related to?

The difficulty of a task.

What characterizes low-load tasks?

They are easy, well-practiced, and use up only a small amount of a person's processing capacity.

What characterizes high-load tasks?

They are difficult and use more of a person's processing capacity.

What was the task in Forster and Lavie's (2008) study?

Participants had to respond quickly to identify a target letter (X or N) surrounded by other letters.

How did reaction times differ between easy and hard tasks in the study?

Reaction times were longer for hard tasks than for easy tasks.

What effect did a task-irrelevant stimulus have on reaction times?

It slowed down responses more for easy tasks than for hard tasks.

What does Lavie's load theory of attention propose?

The ability to ignore task-irrelevant stimuli depends on the load of the task being performed.

What happens during a low-load task according to load theory?

Processing capacity remains available for processing task-irrelevant stimuli.

What happens during a high-load task according to load theory?

No processing capacity remains to process other stimuli, leading to less distraction.

What is endogenous attention?

Attention that is focused voluntarily on a stimulus in a sustained, goal-driven manner.

What is exogenous attention?

Attention that is involuntarily directed toward a stimulus in a transient, fleeting manner.

What is the Stroop effect?

A phenomenon where people find it difficult to name the color of the ink a word is printed in when the word itself is the name of a different color.

Who originally studied the Stroop effect?

J. R. Stroop in 1935.

What causes the difficulty in the Stroop effect?

The competing response caused by the names of the words, which slow the response to the target color.

Why is reading words considered an automatic process?

Because it is highly practiced and becomes difficult to ignore.
