What is test expectancy?
According to some descriptions, (e.g. Craik and Lockhart, 1972) memory is nothing more than a by-product of processing. The depth at which information is processed determines the strength of the memory trace and how easily we can recall it later. Information can be viewed as the raw material for creating knowledge, but the operations we…

Why do we forget what we learned at school?
Do you remember what you learned at school? Chances are you have a vague idea but the details are a bit fuzzy. Or you might not recall anything. Surely, however, if learning really is an ‘alteration in long-term memory’ then we shouldn’t forget what we’ve learned? So, perhaps, we forgot because we didn’t learn it…

The problem with gist
The term ‘gist memory’ usually refers to less detailed long-term memories, often (but not exclusively) episodic memories. However, our semantic memories often rely on these memories of events as we use situational cues to help us recall them. It then follows that errors here can have a knock on effect. When we read a book,…

From Novice to Expert: The Role of Long-term Working Memory
The Dutch psychologist Adriaan de Groot doesn’t always get the same kind of recognition as other cognitive psychologists, his name often restricted to paragraph or two in psychology textbooks or a brief citation in the work of others such as Anders Ericsson, Alan Baddeley and John Sweller. Nevertheless, De Groot has been described as ‘the…

Collaborative learning and Cognitive load
Collaborative learning can be described as two or more learners actively pursuing and contributing to a shared goal, or trying to share the effort required to reach that goal. It has become a mainstay of educational practice. During my time as a teacher there was always an expectation that most lessons would involve some element…

Cognitive load and cognitive offloading
I’ve stated elsewhere that working memory is limited and that these limitations can hamper our ability to learn new things and carry out complex tasks. I’m implying here that learning and remembering are either the same or very similar, so I’m referring to learning in a rather narrow way, but stay with me on this.…

Cognitive Load, emotion and buoyancy
In his 2019 review of twenty years of Cognitive Load Theory, John Sweller explores several avenues of further investigation. One such avenue relates to emotions, stress and uncertainty and how these factors influence cognitive load. Within the education community aspects of cognition in learning are often starkly separated from seemingly non-cognitive factors. Curiously, the former…

What do we really mean by cognitive Load?
The term cognitive load has been around for a long time but definitions have tended to shift and often depend on theoretical positions. Early researchers rarely attempted to define cognitive load at all. In a 1966 paper, Levine describes cognitive load as the amount of information that the observer is required to store in memory…

Does information in short-term memory decay?
The very fact that I’ve posed this as a question rather than a statement probably gives some indication that the answer isn’t exactly straightforward. The notion of decay is a vital component of the short-term/long-term memory distinction, so even asking the question risks casting doubt on an assumption that is almost as old cognitive psychology…

What is Latent learning?
According to Soderstrom and Bjork, latent learning refers to “learning that occurs in the absence of any obvious reinforcement or noticeable behavioural changes” (Soderstrom and Bjork, 2015 p177). Most often associated with the work of Edward Tolman in the 1930s, latent learning is viewed as hidden (or behaviourally silent) because it is only when reinforcement…
