Study Notes
Attention and Perception
- Attention allows individuals to focus on specific stimuli in a noisy environment, as demonstrated by the cocktail party problem.
- When someone says your name in a crowded party, you can focus on that conversation despite the surrounding noise.
The Cocktail Party Problem
- The aspect of perception reduced in the cocktail party problem when attention is directed elsewhere is the ability to process unattended auditory stimuli.
Dichotic Listening Experiment
- The primary purpose of a dichotic listening experiment is to investigate how people process auditory information when presented with two different stimuli simultaneously.
- Auditory stimuli are typically presented to participants through headphones, with one stimulus in one ear and the other stimulus in the other ear.
- Participants typically do not notice changes in the ignored input, such as the meaning of the words or the story being told.
- However, participants usually notice changes in the loudness, pitch, gender of voice, or if their own name is mentioned in the ignored input.
- These changes are examples of semantic features that capture attention.
- The ability to notice changes in the ignored channel suggests that the perceptual process is not strictly filtered out early in the process, but rather, attention is still being directed to the ignored channel.
- Traditionally, it was believed that the ignored channel is filtered out early in the perceptual process, but this has been challenged by experiments.
Triesman and Gelade's Study
- The study revealed that semantic processing occurs in the unattended channel during dichotic listening, contradicting the traditional view.
- The study used stories presented in a dichotic listening experiment, and participants were able to switch to the unattended channel when the story in the attended channel became illogical.
- This suggests that participants are still processing the semantic information in the ignored channel.
Inattentional Blindness
- Inattentional blindness refers to the phenomenon where people fail to notice a stimulus or event because they are focused on something else.
- The "Gorilla in the basketball game" experiment demonstrated this phenomenon, where participants were so focused on counting the number of passes that they failed to notice a person in a gorilla costume walking across the court.
- Inattentional blindness can lead to real-world accidents, such as pedestrians failing to notice a car approaching because they are distracted by their phone.
- Inattentional blindness suggests that attention is necessary for conscious perception, and that we can only process a limited amount of information at a time.
- The strength of the inattentional blindness effect may be influenced by factors such as the complexity of the task or the level of attention required.
Change Blindness
- Change blindness refers to the phenomenon where people fail to notice changes between two images or scenes.
- The flicker paradigm makes it difficult to notice changes between two images by presenting them in rapid succession, making it hard to compare the two images.
- The "door study" by Simons and Levin demonstrated that participants can fail to notice changes to a person, such as when a person walking towards them suddenly changes into a different person.
- The experimenters tested participants' attention and perception by asking them to perform a task while walking, and then suddenly changing the person they were interacting with.
Attentional Blink
- The attentional blink refers to the phenomenon where people fail to notice a second stimulus or event if it occurs shortly after the first stimulus.
- The attentional blink phenomenon illustrates that our attentional processing capacity is limited, and we can only process a certain amount of information in a short period of time.
- The typical experimental setup for studying the attentional blink involves presenting participants with a rapid sequence of visual stimuli, and asking them to detect specific targets or events.
