Speech perception is the process by which spoken language is heard, interpreted and understood. Research in this field seeks to understand how human listeners recognize the sound of speech (or phonetics) and use such information to understand spoken language.
The individual will perceive the sound as coming from the location where the object is seen. Audition can also affect visual perception. Research has demonstrated this effect by showing two objects on a screen, one moving diagonally from top-right to bottom-left and the other from top-left to bottom-right, intersecting in the middle.
While sensation occurs at the physical nerves, there can be reasons why it is not consistent. Age [8] or nerve damage can affect sensation. Similarly, psychological factors can affect perception of physical sensation. Mental state, memory, [9] mental illness, [10] fatigue, and other factors can alter perception.
A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus. [1] The impact of context effects is considered to be part of top-down design. The concept is supported by the theoretical approach to perception known as constructive perception. Context effects can ...
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
Factors of risk perceptions. Risk perception is the subjective judgement that people make about the characteristics and severity of a risk. [1] [2] [3] Risk perceptions often differ from statistical assessments of risk since they are affected by a wide range of affective (emotions, feelings, moods, etc.), cognitive (gravity of events, media coverage, risk-mitigating measures, etc.), contextual ...
Perceptual learning is a more in-depth relationship between experience and perception. Different perceptions of the same sensory input may arise in individuals with different experiences or training. This leads to important issues about the ontology of sensory experience, the relationship between cognition and perception. An example of this is ...
At the same time, research showed that something similar was needed. One alternative concept was attention-deficit hyperactivity disorder (ADHD). Gillberg proposed another alternative: DAMP. Gillberg's concept was formulated in the early 1980s, and the term itself was introduced in a paper that Gillberg published in 1986 (see Gillberg [1986]).
