L2 Processing Information & Making Decisions

These flashcards cover key concepts related to information processing and decision making in humans, as presented in the lecture.

What is the basic premise of information-processing in humans?

Humans act as 'black boxes' that receive information, process it through the CNS, and produce skilled output.

What are the three stages of information processing?

1) Stimulus identification 2) Response selection 3) Movement programming.

What type of sensory input is considered the most powerful and complex?

Visual input.

What is Hick's Law in relation to decision making?

Reaction time increases logarithmically with the number of stimulus-response alternatives.

What are the two types of anticipation that can reduce reaction time?

Spatial anticipation and temporal anticipation.

What is the impact of increased practice on reaction time?

Increased practice can lower reaction time by overcoming disadvantages of low stimulus-response compatibility and high stimulus-response alternatives.

Explain short term memory in relation to information processing.

Short term memory (working memory) is a temporary storage for information that requires rehearsal to prevent loss and lasts a few minutes.

What distinguishes long term memory from short term memory?

Long term memory is essentially limitless and retention is often perfect for motor skills like swimming or biking.

What does the term 'S-R compatibility' refer to?

The extent to which a stimulus and response are naturally connected, affecting reaction time.

How does anticipation benefit elite performers compared to novices?

Elite performers are better at anticipating events, which significantly reduces their reaction time.
