Supervisory attentional system

Supervisory attentional system is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Supervisory attentional system rather than just read about it. In short: Executive functions are a cognitive apparatus that controls and manages cognitive processes. Norman and Shallice (1980) proposed a model on executive functioning of attentional control that specifies how thought and action schemata become activated or suppressed for routine and non-routine circumstances.

Key takeaways

Supervisory attentional system belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Supervisory attentional system to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Supervisory attentional system from memory before moving on to harder problems.

Reference excerpt

Executive functions are a cognitive apparatus that controls and manages cognitive processes. Norman and Shallice (1980) proposed a model on executive functioning of attentional control that specifies how thought and action schemata become activated or suppressed for routine and non-routine circumstances. Schemas, or scripts, specify an individual's series of actions or thoughts under the influence of environmental conditions. Every stimulus condition turns on the activation of a response or schema. The initiation of appropriate schema under routine, well-learned situations is monitored by contention scheduling which laterally inhibits competing schemas for the control of cognitive apparatus. Under unique, non-routine procedures controls schema activation. The SAS is an executive monitoring system that oversees and controls contention scheduling by influencing schema activation probabilities and allowing for general strategies to be applied to novel problems or situations during automatic attentional processes.

Basic background

Executive functions Executive functions are cognitive processes that control other brain activities and are predominantly functioning in the prefrontal areas of the frontal lobe. Executive functions are limited in capacity and accountable for the initiation, consolidation, regulation, and inhibition of cognitive, language, motor and emotional processes. These processes underlie such functions as self-evaluation, planning, problem solving, controlling impulses and attention, and strategic selection or sequencing of behaviour to reach desired goals. Measuring executive functions is often less accurate than measuring non-executive tasks because of the interconnectedness and multi-determined complexity of the brain. Executive functions are hard to measure independently of all other cognitive functions and are often influenced by non-executive factors. Consequently, understanding the relationship between behaviours and cognitive processes can be difficult. Many models of executive functions have been proposed, none of which completely dominates over all others in validity and acceptability. The underlying complexity of the brain makes it very difficult to verify which model(s) are most correct. This article is most focused on the executive function of the Supervisory Attentional System and research pertaining to the system.

Worked examples

Example 1 — a first encounter with Supervisory attentional system

Start with the simplest possible case. Write down what Supervisory attentional system claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Supervisory attentional system before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Supervisory attentional system ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Supervisory attentional system

In research: Supervisory attentional system appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Supervisory attentional system in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Supervisory attentional system is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ageing, Attention deficit hyperactivity disorder, Parkinson's disease, so understanding it makes those chapters shorter.
In everyday life: Look for Supervisory attentional system outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
