The development and use of tools further facilitated this shift, providing early humans with better access to resources and a more varied diet. This, in turn, created selective pressures for larger brains capable of solving problems and creating new technologies. While running, I was daydreaming and spacing out, but also ruminating about all this research in a very laid-back and laissez-faire way. I consciously “unclamped” my prefrontal cortex, and patiently waited for insights to bubble up. ” moment, I dictated a text message to myself into my phone as a reminder, so that I wouldn’t forget about the idea before I got back to my computer to write this blog post.

That said, my primary motivation for writing about cutting-edge neuroscience is to broadcast potentially esoteric findings to a large general audience. My hope is that someone reading this will tap into his or her fluid intelligence, have an “Aha! For example, I woke up around 5AM today and read the new Beckman Institute study for the first time. After making a pot of very strong coffee, I spent about a half hour in an intense cerebral state with laser-focus on trying to understand the nitty-gritty explicit details of the empirical science included in the study using purely crystallized intelligence. In April 2013, a study published by researchers from the School of Child Development at Osaka University Graduate School of Medicine in Japan found that underconnectivity between the cerebellum and other brain regions contributes to many of the features found in autism spectrum disorders (ASD). Crystallized intelligence is a form of declarative memory that represents your lifetime of intellectual, cerebral knowledge.
- John R. Crawford (University of Aberdeen) delivered a meta-analysis of alarge number of frontal tests, including the WCST («stressful anddifficult») and the MCST.
- The effect of brain lesions on WCST performance was then summarised byBrenda Milner of the Montreal Neurological Institute …..
- He expressed mild reservations about Shalliceand Evans’ (1978) CET, but was more positive about Shallice and Burgess’s(1979) Brixton Spatial Anticipation Test and the BADS, both of which have largeeffect sizes.

- MDMA prevents the neurone’s ability to reabsorb serotonin from synapses by binding to and blocking reuptake proteins on the presynaptic membrane.
- «The frontal lobes arethe seat of coordination and fusion of the incoming and outgoing products ofthe several sensory and motor areas of the cortex» (Bianchi, 1895, p34).
- The larger brain allowed for better social cognition, which helped in forming alliances, organizing group hunts, and passing down knowledge through language and culture.
- Global Developmental Delay (GDD)Where the term Global Developmental Delay is used, this means that the difficulties are across the whole of development.
- Also – since surgery reduceddisruptive emotional responses – the ability to interact socially tended toreturn.
A July 2015 study found that dynamic proprioceptive activities—which specifically involve the cerebellum—increased working memory by 50 percent. Working memory creates the mental workspace that facilitates creativity and fluid intelligence. In the passage below, I cobbled together a timeline of various studies I’ve written about in previous Psychology Today blog posts. All of these findings are part of my ongoing attempt to solve the riddle of what role the cerebellum (Latin for “little brain”) plays in cognitive and creative processes.
The Protective Role of the Skull 🔗
Crystallized intelligence is demonstrated largely through your vocabulary and other types of explicit knowledge that you could memorize for a standardized test. Very crudely, fast reaction times imply higher intelligence, slow reaction times lower intelligence, and average reaction times average intelligence. I also want to find out how our ever-changing world could be affecting our cognitive function. Over the last few decades the internet, smart phones and social media have utterly transformed the way we absorb information and interact with one another. In The Great British Intelligence Test we’ll be able to take a look at how this explosion of technology could be affecting our brains and what it might mean for our intelligence – both now and in the future.
Evidence for a ‘critical period’ comes from some ethically-dubious experiments on kittens (see below). Most of our brain is made up of the cerebrum, which is found at the top of the brain. It is divided into two cerebral hemispheres joined together by a band of nerve fibres called the corpus callosum. The cerebrum is involved in ‘higher-brain functions’, such as processing language, vision, thinking and emotions. Since the visual cortex in cats and humans is similar (they both contain ocular dominance columns), Hubel and Wiesel’s results can be applied to humans. This means that humans need to receive visual stimulation from both eyes during the early periods of life for their visual cortex to develop normally.
Followingsurgery, patients did indeed become less anxious and withdrawn, although theirintellectual level remained ostensibly unchanged. Also – since surgery reduceddisruptive emotional responses – the ability to interact socially tended toreturn. It is therefore in close communication with what isknown as the «limbic system», and thus with the full range ofthe brain’s emotional and motivational systems. The prefrontal region ingeneral is commonly linked with such functions as problem solving, behaviourplanning, working memory glossary, and eyemovements.
Mateerand Williams (1991) have studied the effects of frontal lobe injury in childrenand recommend the following classroom management guidelines ….. Othertheorists have highlighted the processes of «reality monitoring»,that is to say, the ability to maintain an accurate internal representation ofthe world and what is going on within it. The key theoretical construct here isJohnson, Hashtroudi, and Lindsay’s (1993) «source monitoringframework» (SMF).
