Question

Accepted Answer

### Question 30
# Brief Explanations:
Iconic memory is a type of sensory memory that deals with visual information and lasts for a very short time (a momentary mental image of the zip code here). Flashbulb memory is for emotionally significant events, echoic is for auditory, state - dependent is about memory retrieval based on state, and implicit is unconscious memory. So the correct answer is related to iconic memory.
# Answer:
E) iconic

### Question 31
# Brief Explanations:
Retroactive interference occurs when new information (new locker combination) interferes with the recall of old information (bicycle lock combination). Proactive interference is old interfering with new, automatic processing is unconscious processing, encoding failure is not getting info into memory, and source amnesia is forgetting the source of a memory. So the correct answer is about retroactive interference.
# Answer:
D) retroactive interference

### Question 32
# Brief Explanations:
Explicit memory is conscious memory of factual information (like facts, events). Implicit is unconscious, procedural is for skills, iconic is sensory visual memory, and proactive is a type of interference. So the correct answer is explicit memory.
# Answer:
A) explicit

### Question 33
# Brief Explanations:
Long - term potentiation (LTP) is defined as an increase in a neuron's firing potential, which is related to how memories are stored at the neural level. The other options describe different memory - related concepts but not LTP.
# Answer:
E) an increase in a neuron's firing potential

### Question (the last one about long - term memory capacity)
# Brief Explanations:
The human capacity for storing long - term memories is essentially unlimited. Hypnosis doesn't enhance it, it doesn't get greatly reduced at 65 (though aging can affect retrieval), the seven units is for short - term memory, and there's no evidence that young children have much greater capacity.
# Answer:
(assuming the option with "essentially unlimited" is, say, option D if we follow the partial display, but from the text, the option is "essentially unlimited")
