B. limited to 7+2 items.
C. retained even though you may not attend to it
D. both A and B.

Answer should be (A).... visual sensory memory duration is approx 0.2-0.3 of a second.

however , watch out . lisachem make many mistakes in multi choice , and they dont explain their answers.

your right of course but I don't get it. how does "visual memory" mean "sensory memory"?

because all the information held in sensory memory is held in a 'sensory register' (there are believed to be five, but we only have to know 2- iconic (visual) and echoic (auditory))

each sensory register has a different duration, which generally serves a purpose.

Iconic memory is VISUAL sensory memory ... visual memory refers to iconic memory.
they worded the question wrong . they should have said .. "visual sensory memory"

but still.

what about these

In operant conditioning the role of the learner is
A) active and volountry
B) passive and volountry
c) active and involountry
d) may be either A or C


Pedro loves to play soccer and particularly loves the terrific feeling he gets he gets wen he kicks a goal. He doesn't score a goal every game, usually he scores only every one or two games, but he keeps on playing, hoping he will score. Pedro is operating on a
A) variable interval "SoR"
B) fixed interval "SoR"
C) variable ratio "SoR"
D) fixed ratio "SoR"

Which of the following is most likely an example of forgetting due to lack of consolidation
A) Perry is unable to recall the novels he read in Year 11 but when he looks at the reccommended reading list he has no difficulty in selecting the correct novels
B)Lauren was trying to memorise a list of psych definitions when a fight broke out in the library, just as she had finished reading through them. When Lauren tested herself later stage could not recall any of the definitions
C)Jennifer fell and was knocked unconscious. She was taken to hospital but when she regained conscioussness she had no recollection of how she got to the hospital
D)Karl witnessed a fatal car accident  and was deeply distressed by the event. When he was questioned by police about the accident, he could not recall any of the details

thanks

i should have just inboxed u lol coz u always get them right. can u explain. they are from insight but i still don't the explanations
1 I wrote a because I though operant conditioning is volountry. Now that I think about it you are right but I'm sure it doesn't say this in the textbook
2 Very confident I was correct with variable interval. explain?
3 Was tossing up between B and C but went for C. Both seem to be right?
thanks

I agree with you matt, but I do find it hard to understand why 3 couldn't be C

apparently, C counts as retrograde amnesia only, but wouldn't that also involve the disruption of consolidation?

1 Operant conditioning doesn't have to involve voluntary actions -> for example you can use operant conditioning on say autism. Now you can't really say that autism is a voluntary condition, could you?
2 Isn't time based. The 'reward', being the getting goals, is received every time a person received a goal. It's not given say every 15 minutes, hence the ratio. It's obviously variable cause he doesn't get goals every match.
3 Well, I'd suppose it depends on the length of time it took for the ambulance to get to Jen, pick her up and get her to the hospital. Remember, consolidation is only affected in regards to memories gained 30 minutes prior.
