Subliminal Perception

Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Higher Mental Functions of the Brain: Language

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Interference and Decay

Interference and Decay

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Subconsciousness and No Awareness

Subconsciousness and No Awareness

The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Dementia

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Area of Science:

Linguistics
Sociolinguistics
Gerontology

Background:

Subliminal linguistic effects are common in daily interactions but difficult to study empirically.
Previous observations suggest these effects manifest differently in individuals with dementia.
Micro-interactional analysis of these effects in dementia care is lacking.

Purpose of the Study:

To conduct the first systematic micro-analysis of subliminal linguistic effects in dementia communication.
To explore how people with dementia operationalise subliminal linguistic effects.
To investigate potential non-intrusive measures for cognitive impairment assessment.

Main Methods:

Utilisation of conversation analysis (CA).
Analysis of over 200 hours of naturalistic multiparty field recordings.
Focus on two UK dementia care settings.

Main Results:

Demonstrated the possibility of capturing subliminal linguistic effects in naturalistic settings.
Identified micro-interactional features associated with these effects in dementia communication.
Provided the first systematic micro-analysis of the phenomenon.

Conclusions:

Subliminal linguistic effects can be empirically studied in naturalistic dementia communication.
Specific micro-interactional features may indicate cognitive impairment.
This research could lead to novel, non-intrusive cognitive assessment tools.
