COGNITIVE PROCESSES (MEMORY) - Working Memory Model (Landry and Bartling)

14 important questions on COGNITIVE PROCESSES (MEMORY) - Working Memory Model (Landry and Bartling)

What is the Working Memory Model proposed by Baddeley and Hitch?

The Working Memory Model suggests short-term memory is a system with parts handling different information types, like words and images. It explains active information use during tasks.

How was each trial scored in the experiment?

Trials were scored based on recall accuracy. They were counted as correct only if letters were in the correct position. This was repeated ten times for accuracy assessment.

Describe the role of the Central Executive in the Working Memory Model.

The Central Executive organizes information, acts like a manager, determines information but relies on slave systems to store it. It has limited capacity.

What were the findings regarding the experimental and control groups' scores?

The experimental group scored a mean percentage of 45% (accurate recall), while the control group scored 76%. Despite large mean differences, standard deviations were similar.

What is the function of the Phonological Loop in the Working Memory Model?

The Phonological Loop is a temporary store for auditory information. It includes the phonological loop (inner ear) and articulatory process (inner voice).

What do the results support in terms of psychological models?

Results support the experimental hypothesis and the Working Memory Model. Participants in the experimental condition found it harder to memorize the letter list.

Explain the Visuo-spatial Sketchpad in the Working Memory Model.

The Visuo-spatial Sketchpad is responsible for spatial and visual awareness. The Visual Cache stores visual data, and the Inner Scribe records object arrangements.

What are the strengths of the task used in the study?

The task was highly controlled, facilitating fair comparison between conditions. It provides useful evidence for WMM, especially regarding the phonological loop.

What is the role of the Episodic Buffer in the Working Memory Model?

  • Interaction between working memory and long term memory.
  • Able to dual task when using two parts of the function

What are the limitations of the task in the study?

The task was artificial, not reflecting everyday memory use, leading to low ecological validity. The sample may not represent everyone, affecting generalizability.

What was the aim of the Landry and Bartling (2011) study?

The aim was to investigate if articulatory suppression influences recall of a written list of phonologically dissimilar letters in serial recall.

Describe the procedure used in the Landry and Bartling (2011) study.

Participants were tested individually. The experimental group recalled letters while saying numbers 1 and 2. The control group saw the list but didn't do the suppression task.

What was the task for the experimental group in the Landry and Bartling (2011) study?

In the experimental group, participants saw a list of letters to recall while saying numbers 1 and 2 simultaneously, performing the articulatory suppression task.

What was the control group's task in the Landry and Bartling (2011) study?

The control group saw the list of letters but did not perform the articulatory suppression task, attempting to write letters in order after 5 seconds.
