J Child Psychol Psychiatr, 55: 31-38. https://doi.org/10.1111/jcpp.12089

34 children and adolescents with diagnosed PTSD following the Sichuan earthquake and 66 matched controls exposed to the same earthquake but without PTSD

Children and adolescents with PTSD performed worse in day-to-day tasks 4 months after the earthquake whenever emotional control was needed, but there was no difference between the groups in their everyday performance at the 12-month assessment after controlling for the potential confounding effects of age and the 4-month rating. Daily executive function did not improve in either group during the 8-month period between test administrations.

This study examined these relations among young children in three Asian countries.

Overall EF was positively associated with oral language and literacy after controlling for age, socio-demographic variables, and country.

Specific patterns of relations between EF components and language were observed across contexts.

'Across countries, bilingual children are shown to outperform their monolingual peers. Task improvement with age is not consistently reported in all studies, with no linear effects apparent in children from developing countries or regions. Gender differences on EF measures also vary between countries. Girls perform better than boys on EF tasks and parent and teacher ratings of EF in both Western and East Asian samples. Yet, in Iran and Tanzania, boys receive higher EF scores. From preschool age through adolescence, East Asians outperform Western counterparts on direct assessment measures of EF. However, strong discrepancies can be found between measures of direct EF assessment and parent and teacher ratings of children's EF. Chinese parents rate their children's EF as lower compared with parents from other countries.'

Cultural variation in cognitive flexibility- Legare et al. 2018

2023-10-09 10:47:22 UTC

Study used 3-5 yo children from English speaking US, and Tswana speaking South Africa, and tested performance on a word learning test, and a rule switching test.

Results: found same developmental trajectory for word learning test, but South African children did not show the same age-related performance increase in the rule switching test.

It was hypothesised that the difference may be due to different rule switching flexibilities prevalent in different cultures, where as word learning has less cross cultural variability

Participants were 7,797 children (3,889 girls) between 36 and 72 months of age from 6 countries in East Asia and the Pacific. 3 salient findings: First, gross and fine motor skills predicted both language and literacy and mathematics achievement. Second, in general, fine motor skills contributed more to the prediction of early achievement than gross motor skills. However, there were no differences between the contributions of fine and gross motor skills to the prediction of early language and literacy in Papua New Guinea or early mathematics in Timor-Leste. Third, EF partially mediated the relation between both early achievement and gross and fine motor skills in the overall sample, Cambodia, and Timor-Leste and fully mediated the association of gross motor skills and early achievement in China, Mongolia, Papua New Guinea, and Vanuatu.

Schirmbeck et al. Contrasting executive function development among primary school children from Hong Kong and Germany. (2021)
A cross-sectional pilot study was carried out to assess EF development in primary age kids in Hong Kong and Germany. It was to look further into previous research that suggested East Asian children had a development lead compared to children from the USA, Canada and UK in earlier childhood. This study wanted to see if this is also the case in middle childhood. The country representing the West here was Germany and the region representing the East was Hong Kong. The study didn’t find any significant interactions between age, region and EF performance in primary school kids. The researchers suggest that it could be due to characteristics specific to Hong Kong and Germany, however I’m not sure if these findings contradict previous ones that indicate a development lead for some kids in Eastern countries (unsure which countries) or if they do not contradict since may be there was a development lead at an earlier age???

First published: 07 January 2020

https://doi.org/10.1002/icd.216

Sample 4418 publications with two variables of interest: (a) Assessment of at least one facet of EF (inhibition, updating, shifting) in populations of children or adolescents and (b) a comparison across cultures—to be precise, a comparison between two or more countries within one study.

The research that have been evaluated clearly demonstrated that cultural context influences EF development. There were similarities and variances in the developing patterns of EF across countries.

2023-10-09 11:00:50 UTC

Chinese pre-school children outperform US kids on EF tasks but there was no difference in theory of mind scores if verbal ability. Could be due to sociocultural and genetic factors- Chinese parents expect children as young as 2 to master impulse control whereas they do not in the US.
inhibition is taught and controlled much younger in China.

'U.S. and South African children did not differ in word-learning flexibility but showed similar age-related increases. In contrast, U.S. preschoolers showed an age-related increase in rule-switching flexibility but South African children did not' (Legare et al., 2018)

'The finding show rule-switching flexibility might be more dependent upon particular kinds of cultural experiences, whereas word-learning flexibility is less cross-culturally variable' (Legare et al., 2018)

Milosavljevic, B., Cook, C. J., Fadera, T., Ghillia, G., Howard, S. J., Makaula, H., Mbye, E., McCann, S., Merkley, R., Mshudulu, M., Saidykhan, M., Touray, E., Tshetu, N., Elwell, C., Moore, S. E., Scerif, G., Draper, C. E., & Lloyd-Fox, S. (2023). Executive functioning skills and their environmental predictors among pre-school aged children in South Africa and The Gambia. Developmental Science, 00, e13407. https://doi.org/10.1111/desc.13407

Examined EFs among children aged 3-5yo in South Africa(SA) and The Gambia & explored shared and distinct predictors of EF. SA sample N = 243, of which 51.9% female; TG sample N = 171, 59.7% female. EF, working memory, inihibitory control, and cognitive flexibility all testing utilising tablet-based tasks (potential for cultural incompatibility where tablets are not widely utilised). Association between EF performance and family enrichment factors and socioeconomic status assessed.

Participants in SA scored higher on all EF tasks, but children in both sites predominantly scored within the expected range for their age. No association between EFs and household or familial variables in SA, except for a trend-level association between caregiver education and CF.

can you repeat the bit about in childhood its about where the brain areas are but in adulthood its about where the connections are

2023-10-09 11:23:07 UTC

2023-10-09 11:23:54 UTC

Are there any sex differences in EF development, e.g are the differences between boys and girls smaller than during puberty/ are there any differences at all?

2023-10-09 11:25:00 UTC

if white matter increases throughout childhood and adulthood, why is it non linear?

if white matter is the connections, and the development is all about changing connections, then why is grey matter the last to keep developing, why is it not all about the white matter?

2023-10-09 11:33:37 UTC

2023-10-09 11:35:26 UTC

Why are brain areas which are used for the same function, e.g. talking, located around different regions of the brain?
Why can't they all be located in just one area of the brain, is it an evolutionary or adaptive purpose?

Thank u that was acc a rlly interesting lecture :)

2023-10-16 10:25:53 UTC

2023-10-16 10:26:09 UTC

visuo-spatial working memory is significantly impaired whereas verbal working memory has a smaller effect

lecture three question:

2023-10-16 15:36:41 UTC

Since ADHD seems to vary per individual, and isn't really set in stone as to what symptoms one may show, would ADHD then classify as a spectrum disorder, like autism?
What are some examples of disorders that are not a spectrum disorder, as there are many which do vary per individual?

2023-11-06 11:52:39 UTC

individual brain changes across participants over time

2023-11-06 11:53:03 UTC

There not being a strict enough criteria for the diagnosis of DCD

include a stricter criteria for the diagnosis of the disorder and only including these participants

2023-11-06 11:56:57 UTC

samples are too small

2023-11-06 11:57:40 UTC

Too few mri studies - used more advanced neuorimaging techniques at resting stage or during studies

Samples are too small and non-homogenous > include more homogenous with strict inclusion criteria for DCD and TD

Chose not to look for co-morbidities other than usual ones - take into account SLI and DD
Cluster sizes below 50 - recruit more people and pay careful attention to imaging data

2023-11-06 11:57:50 UTC

many authors didn’t check for comorbidity of other disorders.

Should include more homogenous subtypes of DCD, so excluding ppts with ASD, ADHD, DD and SLI will help distinguish the unique brain characteristics of DCD

2023-11-06 12:01:10 UTC

Samples are small and non-homogenous

2023-11-06 12:02:01 UTC

Use more advanced neuroimaging techniques such as DTI

2023-11-06 12:02:31 UTC

Tasks need to be consistent across studies.

Same diagnostic tests and cutoff scores across multiple studies

2023-11-06 12:03:36 UTC

Test to see which areas of the cerebellum or BG were activated through tasks to better understand functions and see differences

2023-11-06 12:04:23 UTC

Results not adjusted for multiple comparisons. More open to type 1 errors

children pre-term are physically smaller. may struggle with walking because of that

2023-12-04 12:08:58 UTC

2023-12-04 12:09:10 UTC

Attentional lapses could cause child to move onto something else rather than showing parent what they made

2023-12-04 12:10:23 UTC

Child not developed in utero to full term so may be overwhelmed by the environment and more likely to feel sensory overload

2023-12-04 12:10:44 UTC

Motor problems, visuo-spatial impairments, speed of processing

2023-12-04 12:10:51 UTC

preterm babies have a smaller brain size- may be linked to less development in sensorimotor areas.

2023-12-04 12:11:20 UTC

speed of processing slow so may not respond to their name

Will we get marked down for referring to e.g. ADHD as a neurodevelopmental disorder, or do you want us to stick to neurodevelopmental difference?

2023-12-11 10:04:55 UTC

2023-12-11 10:05:08 UTC

Reading week

2023-12-11 11:09:23 UTC

What counts as wider reading? If I read the core and recommended reading in greater detail does that count as wider reading or does it have to be content that has not been covered at all during the lectures?

Hello, Is this a take home exam or in an invigilated room with pc?

lpxpa2_ — 2023-12-11 11:10:59 UTC

2023-12-11 11:11:14 UTC

Is the exam 2 hours, + 30 minutes for upload time, or is it 2 hours 30 minutes + 30 minutes upload time?

References

2023-12-11 11:16:27 UTC

If we cite a paper that has not been covered in the lecture, are we required to provide a reference for it?

once we submit our essay can we re submit during the 2.5 hours

2023-12-11 11:16:33 UTC

Do you recommend spending an hour on each question or longer on the essay?

2023-12-11 11:17:04 UTC

2023-12-11 11:17:14 UTC

Are the essay and the scenario equally weighted?

2023-12-11 11:17:15 UTC

Will we be getting applied scenario topics as last years are uploaded?

when will the exam timetable be released

2023-12-11 11:19:05 UTC

2023-12-11 11:25:55 UTC

Is there still an equal chance that the applied scenario topics may be used for essay questions?

2023-12-11 11:31:53 UTC

When is the exam? or when do we get our exam timetables?

Subheadings

2023-12-11 11:50:26 UTC

Do you recommend using these for structure?

2023-12-11 11:50:34 UTC

At the end of the module

2023-12-11 11:53:40 UTC

at the start so you can have it in your mind as you're going through lectures

2023-12-11 11:54:53 UTC

just checking we don't need a bibliography for either the essay OR scenarios? Just in text citations?

I think this has already been covered, but I'm a little confused. So, do we get the exam questions prior to the exam? If so, how far in advance do we get these?

2023-12-11 11:56:10 UTC

2023-12-11 11:59:29 UTC

A brief 10 minute overview in the first lecture then a session like this at the end

At the start, so we know what to expect and can start independent revision as we go through the lectures - I find this the most helpful

2023-12-11 12:03:48 UTC

2023-12-11 12:12:19 UTC

If applied scenarios are asking us to make a leaflet, do we need to format our answer like this? or just provide the text that would go on the leaflet?

So when do we get the applied scenario topics etc?

2023-12-11 12:18:14 UTC

2023-12-11 12:21:15 UTC

Do we have to give a citation for definitions or can we just write one ourselves from our general understanding?

Would be best if covered at the start & at the end

2023-12-11 12:25:42 UTC

2023-12-11 12:30:53 UTC

Could multiple questions about one topic come up? or would a topic just come up once.

2023-12-11 12:38:55 UTC

When do we get the applied scenario topics?

2023-12-11 12:39:33 UTC

As we are given topics for the applied scenario does this mean they won’t be in the normal essay questions?
