Learning — Important Questions

In escape learning, the organism acts after the aversive stimulus begins; in avoidance learning, it acts before the stimulus occurs

Step 1: Both escape and avoidance learning are subtypes of negative reinforcement — both involve an aversive stimulus (like an electric shock). Step 2: The key difference is TIMING of the organism's response relative to the aversive stimulus. Step 3: Escape learning — the aversive stimulus is already ON and the organism responds to STOP or ESCAPE it. Example: Rat is already being shocked and presses lever to stop the shock. Step 4: Avoidance learning — the organism learns to act BEFORE the aversive stimulus arrives, thereby avoiding it completely. Example: A warning signal appears; rat presses

Spaced practice involving several shorter study sessions

Step 1: The chapter specifically discusses study habits under tips for better learning. Step 2: Massed practice refers to studying in one or two long sessions, which is less effective for long-term retention. Step 3: Spaced practice involves spreading study across many shorter sessions over time — this is scientifically proven to improve memory and learning. Step 4: The chapter explicitly states: 'Spaced practice is a more efficient way to study — involves a large number of relatively short study sessions, rather than one or two long ones.' Step 5: Options A, C, and D go against the recommende

A relatively durable change in behaviour due to experience

Step 1: The chapter defines learning precisely — understanding each word in the definition is critical. Step 2: 'Relatively durable' means the change should last for a reasonable time — not just momentarily. Temporary changes (due to illness or drugs) do NOT count as learning. Step 3: 'Due to experience' is the most critical part — the change must result from practice or experience. Maturational changes (like a child learning to walk at a certain age) and instinctive behaviours do NOT count because they are not driven by experience. Step 4: Option A is too broad — it includes changes due to ma

It is a biologically important stimulus that naturally elicits an unconditioned response

Step 1: In Pavlov's experiment, different stimuli play different roles — understanding each one is important. Step 2: The Unconditioned Stimulus (UCS) is a stimulus that NATURALLY produces a response WITHOUT any prior learning or conditioning. In Pavlov's experiment, food is the UCS because dogs naturally salivate to food. Step 3: The key word is 'naturally' — no training is needed. That is why it is called 'unconditioned' (not learned). Step 4: Option A describes a Neutral Stimulus (NS) — like the buzzer before conditioning. Option B describes the Conditioned Stimulus (CS) — the buzzer after
