Questions and Answers

What does 'modality-specific' describe regarding the coding of the sensory register?

  • It depends on the sensory organ involved in receiving the information. (correct)
  • It relates to the distinctiveness of the information being processed.
  • It refers to information coded for long-term storage.
  • It is specific to the individual's emotional state during encoding.

Which of the following best describes the capacity of the sensory register?

  • Very large, possibly unlimited. (correct)
  • Approximately 18-30 seconds worth of sensory input.
  • Limited to the amount of information that can be rehearsed in 2 seconds.
  • Around seven plus or minus two chunks of information.

In Baddeley's study on coding in short-term memory, which type of word list presented the most difficulty for participants to recall?

  • Semantically similar words.
  • Acoustically dissimilar words.
  • Acoustically similar words. (correct)

Modality-Specific Coding

Coding that depends on the sensory organ (e.g., visual, auditory).

Sensory Register Capacity

The sensory register has a very large, possibly unlimited, capacity for storing sensory information.

Baddeley's Coding Study: STM

Acoustically similar words (words that sound alike) were more difficult to recall in short-term memory due to acoustic confusion.

Most Resistant LTM

Procedural memory, which stores skills and habits, is the most durable type of long-term memory.

Study Notes

  • Modality-specific in sensory register coding means it relies on the specific sensory organ involved.
  • The sensory register has a very large, possibly unlimited capacity.
  • Acoustically similar words were the most difficult to recall in the short-term memory condition in Baddeley's study on coding.
  • Procedural long-term memory is most resistant to forgetting.
  • Clive Wearing experienced both retrograde and anterograde amnesia due to brain damage.
  • Recall was best in Overton's research when information was learned in the same state.
  • Categorised recall resulted in significantly better recall in Tulving and Pearlstone's research.
  • Interference theory and cue-dependent forgetting have practical applications.
  • In Yuille and Cutshall's study, witnesses closest to the shooter (high anxiety) had the best recall.
  • 71% of participants included items they hadn't seen in Gabbert's study.
  • Kohnken's meta-analysis of cognitive interviews revealed the interview increased accurate information and more.
  • Detectives gained 47% more information after cognitive interview training, according to Fisher.
