what is cognitive psychology?
The scientific study of how people think and
process information. Includes:
- Attention
- Decision Making
- Language
- Memory
why study language?
Language makes us human
* (almost) every human knows and uses language.
* No other species has language as complex and powerful as we do.
What would the world be like without language?
* Everything would be a lot more difficult
– Social interactions
– Cooperation
– Transmission of information
* How to convey abstract notions?
* Science? Culture?
the world would be impoverished without language
key questions we can address
- How do we develop language?
- How can we communicate more effectively?
- How do we acquire concepts and categories?
- How can we help people with communication
difficulties?
why study memory?
- It contains everything we know!
- It tells us who we are, our memories contribute
to our sense of “self”. - events and autobiographical memories = episodic - It provides the words and the grammar to communicate, our knowledge of the world. - semantic
- Memory holds our skills e.g. riding a bike. - procedural
- It allows us to follow instructions
memory key questions we can address
- What techniques are most effective for
remembering? - How can we do (or not!) mental arithmetic?
- Why do we forget?
- What about people with memory problems?
why study language and memory?
- Knowing about memory and language is
useful for society - Memory and language are a core part of
being human
The language you speak can affect your working memory
two main forms of languages
* Right-branching (RB) e.g. Italian. Head of the sentence comes first, followed by modifiers that provide additional information (e.g. “the man who was sitting at the bus stop”). Process info incrementally.
* Left-branching (LB) e.g. Japanese. Modifiers generally precede heads (e.g. “who was sitting at the bus stop, the man”). Ambiguous until the end - need to retain modifiers to understand sentence meaning
head = the man
amici (2019)
- “The main finding of the study is that
left-branching speakers were better at
remembering initial stimuli across
verbal and non-verbal working memory
tasks, probably because real-time
sentence comprehension heavily relies
on retaining initial information in LB
languages, but not in RB languages”,
shows there are relationships between language and memory
Language and Memory
- Many phenomena engage both processes.
- Language can affect memory; memory
can affect language
if things are semantically related we remember them better - link between language and memory
Roediger & Karpicke (2006)
Repeated study:
Repeated study:
Passage read 4
times, no test.
Single test:
Passage read 3
times and then
students recall as
much as possible.
Repeated test:
Read once and
then recalled as
much as possible
on 3 occasions.
Average recall was 50% higher in the
repeated test condition compared to
repeated study. Robust effect - in one week condition.
there was a 5 minute and one week condition
Why do students prefer
studying to testing?
- Repeated studying produces short-term
benefits. - Students who repeatedly study think that they
will recall more after a week than those who
repeatedly test i.e. poor metacognitive
awareness. - Studying is less effortful and demanding than
testing, and this makes it more appealing.
the generation effect
reading is not good enough alone as a method of learning new content.
we need to generate or create something new with the learning.
taking an active role in producing learning increases the strength of the memory.
