RAF Airman/Airwoman Selection Test (AST) Memory Syllabus

What cognitive skill is being tested when you 'hold letters in mind while ignoring distractors'?

Selective attention combined with working-memory maintenance — keeping target items active while inhibiting (filtering out) irrelevant distractor items.

What is 'selective attention'?

The ability to focus cognitive resources on relevant (target) information while suppressing or ignoring irrelevant or distracting information.

What is 'inhibition' in the context of working memory?

The active suppression of irrelevant or distracting information so it does not enter or disrupt the contents of working memory.

What is a 'dual-task' in the AST Memory context?

Performing two demands at once — for example, retaining the illuminated pattern sequence WHILE simultaneously processing the letters-and-distractors task — testing divided attention.

What is 'divided attention'?

Splitting limited attentional resources across two or more tasks at the same time, which usually reduces performance on each compared with doing them singly.

Why does dual-tasking typically reduce memory accuracy?

Because attention and working-memory capacity are limited; sharing them between two tasks means fewer resources are available to encode and maintain each, increasing errors.

What is 'updating' in working memory?

Continuously replacing or revising the items held in mind as new information arrives, discarding outdated items and keeping the set current.

Give a practical example of memory 'updating' during the AST.

As each new letter or pattern appears, you drop the oldest no-longer-needed item and add the new one — keeping only the most recent required items in mind, like a moving window.

What working-memory component (in Baddeley's model) handles visual/spatial pattern information?

The visuospatial sketchpad — the subsystem that temporarily stores and manipulates visual and spatial information such as the layout of illuminated squares.

What working-memory component (in Baddeley's model) handles verbal/letter information?

The phonological loop — the subsystem that holds and rehearses speech-based/verbal information such as letters and numbers.

In Baddeley's working-memory model, what does the 'central executive' do?

It is the attentional control system that directs focus, coordinates the subsystems (phonological loop and visuospatial sketchpad), divides attention for dual tasks, and inhibits distractors.

Why are the visual pattern task and the verbal letter task in the AST relatively easy to do together?

They use different working-memory subsystems (visuospatial sketchpad vs phonological loop), so they interfere less than two tasks that compete for the same subsystem.

What is 'maintenance rehearsal'?

Repeatedly going over information (e.g., silently repeating letters) to keep it active in short-term memory and prevent decay.

What is 'subvocal rehearsal' and which task does it help in the AST?

Silently 'saying' items to yourself inside your head; it refreshes the phonological loop and helps retain the target LETTERS while ignoring distractors.

What is the 'recency effect' in serial recall?

The tendency to recall the LAST items in a sequence best, because they are still held in short-term memory at the moment of recall.

What is the 'primacy effect' in serial recall?

The tendency to recall the FIRST items in a sequence well, because they received more rehearsal and were more likely transferred to longer-term storage.

Together, what pattern do the primacy and recency effects produce?

The serial position curve — a U-shaped accuracy curve where items at the start and end of a list are recalled better than items in the middle.

Why are MIDDLE items in a sequence the hardest to recall?

They benefit from neither strong early rehearsal (primacy) nor still being in short-term store at recall (recency), and they suffer interference from items on both sides.

What does 'maintaining concentration under time pressure' require during the AST?

Sustained attention (vigilance) — keeping focus consistently high across many rapid trials without lapses, despite the speed and stress of the timed format.

What is 'sustained attention' (vigilance)?

The ability to maintain a consistent level of focus and responsiveness on a task over a continuous period of time.

How does time pressure tend to affect working-memory performance?

It raises cognitive load and arousal; moderate pressure can sharpen focus, but excessive pressure causes rushed encoding, lapses, and more errors (memory overload).

What is 'cognitive load'?

The total amount of mental effort/working-memory resources being used at a given moment; when load exceeds capacity, performance drops and errors rise.

What is 'memory overload' and how can staying calm prevent it?

Overload occurs when you try to hold more than capacity allows, so items are lost. Staying calm lowers anxiety-driven distraction, freeing working-memory resources and keeping load manageable.

According to the Yerkes-Dodson law, how does arousal (stress) relate to performance?

Performance follows an inverted-U: it improves as arousal rises to an optimal level, then declines if arousal becomes too high — so moderate, not extreme, stress is best.

How does anxiety specifically harm working memory?

Worry and intrusive thoughts consume central-executive resources, leaving less capacity to encode, hold, and manipulate the target information.

Name two relaxation techniques that help keep memory performance stable under exam pressure.

Controlled/diaphragmatic breathing (slow deep breaths) and positive self-talk/refocusing on the current item rather than past mistakes.

What is a 'rapid recall drill' and why practise it for the AST?

A timed practice exercise that repeatedly trains fast encoding and retrieval of patterns or letters; practice builds speed, accuracy, and automaticity so less effort is needed under real test pressure.

What is 'automaticity' and why is it valuable in the Memory test?

Automaticity is performing a process quickly with little conscious effort after practice; it frees working-memory capacity for the harder parts of the task and improves speed under time pressure.

Why is spaced repetition an effective revision strategy for the AST Memory skills?

Reviewing material at increasing intervals strengthens long-term retention more than cramming (the spacing effect), and repeated retrieval practice builds the fast, reliable recall the timed test demands.

Summarise the best overall strategy for the AST Memory test in one sentence.

Encode patterns quickly as a whole, chunk and rehearse the target letters while actively ignoring distractors, update your held items as new ones appear, and stay calm and focused to keep cognitive load below your working-memory capacity.
