  • What was the aim of the study on shift work adaptation?
    To determine if light exposure prevents adaptation issues
  • How many men participated in the shift work study?
    8 men
  • What was the age range of the participants in the study?
    In their 20s
  • What was the light exposure for the experimental group?
    700 to 12000 lux
  • What did the control group experience in terms of light exposure?
    150 lux
  • What activities did participants perform during their shifts?
    They did cognitive tests and reported alertness
  • What was the treatment for the experimental group after their shift?
    They remained in the dark from 9 to 5 pm
  • What biological measure indicated a change in the experimental group?
    Body temperature showed circadian rhythm adjustment
  • How much did the circadian rhythms of the experimental group shift?
    Forward by over nine hours
  • What was the result of alertness and cognitive tasks for the experimental group?
    They were similarly shifted
  • What improvements were noted in the experimental group?
    Lower body temperature and better work performance
  • What was a significant statistical finding between the control and experimental groups?
    The mean low point of body temperature was huge
  • What was a limitation regarding the sample size of the study?
    It was very small and only men
  • What extraneous variables were not fully controlled in the study?
    When they ate breakfast and sleep duration
  • What are the key features of the multi-store model of memory?
    • Sensory register: very brief memory from senses
    • Short-term memory: immediate use, limited duration
    • Long-term memory: permanent storage, high capacity
    • Information transfer: attention and rehearsal needed
  • What is the duration limit of short-term memory without rehearsal?
    18 seconds
  • What is the capacity of short-term memory according to Miller?
    Around 7 items
  • What type of coding is primarily used in short-term memory?
    Acoustic coding
  • What is the difference between procedural and declarative memories?
    Procedural is knowing how; declarative is knowing that
  • What is the serial position effect as found by Murdock?
    • Primary effect: better recall of first items
    • Recency effect: better recall of last items
    • Middle items are recalled poorly
  • What is a strength of Murdock's study on memory?
    It supports the multi-store model
  • What is a weakness of Murdock's study?
    Used lists of words, not meaningful
  • What are the strengths and weaknesses of the multi-store model?
    Strengths:
    • Detailed description of short-term memory
    • Allows for experimental research

    Weaknesses:
    • Too simplistic and inflexible
    • Doesn't explain attention or forgetting
  • What does the working memory model propose about short-term memory?
    It is a flexible active store for tasks
  • What are the components of the working memory model?
    Central executive, phonological loop, visuospatial sketchpad
  • What is the role of the central executive in the working memory model?
    It manages attention and decision-making
  • What does the phonological loop deal with?
    Auditory and acoustic information
  • What is the capacity of the visuospatial sketchpad?
    4 objects
  • What is the function of the episodic buffer?
    Combines sights and sounds into coherent episodes
  • What evidence supports the working memory model?
    Patient KF had selective memory impairments
  • What is trace decay in memory theory?
    Forgetting due to fading memory traces
  • What does interference theory suggest about forgetting?
    Similar memories compete and disrupt each other
  • What are the two types of interference?
    Proactive and retroactive interference
  • What is the encoding specificity principle?
    Cues must match at encoding and retrieval
  • What did Godden and Baddeley's study find about context-dependent cues?
    40% more words recalled in the same context
  • What is state-dependent memory?
    Recall depends on internal cues like mood
  • What is a limitation of context-dependent cues?
    Contexts must be very different for effects
  • What are the two types of amnesia caused by brain damage?
    Retrograde and anterograde amnesia
  • What is retroactive interference?
    New memories interfere with older memories
  • What did Baddeley et al. find about word length effect?
    Memory span is related to word length
