Key evidence an nummers
| Findin fae the spatial-trainin synthesis | Interpretation |
|---|---|
| 217 studies examined | A wide range o spatial interventions |
| Analysis kept: 206 studies, 1,038 effect sizes | The analysis ahint the estimate efter ootliers were left oot |
| Average g = 0.47 efter ootliers were left oot | A moderate standardised trainin effect |
| Transfer tae ither spatial tasks | Some generalisation within the spatial domain |
| Different tasks and control conditions | Nae universal personal trainin dose or gain |
The synthesis considers how lang effects last, factors that affect them, and transfer. It covers mair than reviews o interventions focused on heid-turnin alane. Its results back the idea that spatial skills can change wi practice, while no provin that ilka brief online gemme reproduces the average intervention or changes general intelligence. Uttal et al., 2013
Whit exactly can get better?
The classic heid-turnin experiment measures matchin objects at different angles. Ither tests add mair items, different distractors or strict time limits. Performance can reflect learnin the task's rules and strategies as weel as changes in how efficiently it is solved. The outcome needs tae say whether it measures accuracy, speed or the item set. Shepard et al., 1971 Vandenberg et al., 1978
Retest research records gains across repeated cognitive tests, sae a second try by itsel isnae a controlled trainin experiment. A useful evaluation maun tell ordinary familiarity apart fae the additional effect o an intervention. Scharfen et al., 2018
Does practice help ilka body the same?
The meta-analysis disnae support identical personal gains. It looks at differences atween interventions and participants, includin age and sex, but a pooled effect cannae predict ae person's improvement. Likewise, historical reviews o sex differences describe averages that depend on the task, no fixed limits for individuals. Uttal et al., 2013 Voyer et al., 1995 Linn et al., 1985
Whit affects it?
Does improvement carry ower tae mair than the gemme?
Transfer tae spatial tasks that havenae been practised is a mair informative result than improvement on repeated items alane, and the synthesis reports sic transfer. That is still mair limited than better performance in ilka real-world spatial activity or a rise in overall intelligence. Hou similar the trainin and assessment are matters for whit can be claimed. Uttal et al., 2013
Hou can ye avoid mistakin a change o strategy for a new ability?
Record the task version, timing and previous experience. If ye start uisin a different comparison strategy, that can be useful learnin, but describe it as pairt o the change. A result on ae set o shapes disnae on its ain prove a general spatial score. Shepard et al., 1971 Vandenberg et al., 1978
Measurement noise matters an aa. The reliability-paradox study shows that classic task results can be robust at group level while givin unstable individual differences. A sma change atween short sessions shouldnae be ower-interpreted as a permanent shift. Hedge et al., 2017
Whit's a realistic practice goal?
Aim tae solve comparable unfamiliar items mair accurately and efficiently, and keep baith results in view. The cited synthesis disnae establish a universal daily duration, number o sessions or target score for this browser task. It backs the possibility o learnin, no a personal forecast. Uttal et al., 2013 Scharfen et al., 2018
Avoid explainin early difficulty wi a sex stereotype. The group research and the wider review o similarities dinnae decide an individual's potential. Current performance and the ability tae learn are different questions. Voyer et al., 1995 Hyde, 2005
Sae the honest claim aboot benefits is specific: spatial trainin has evidence for average improvements, includin some transfer within the same domain, under the conditions studied. Whether practice wi a particular gemme leads tae a particular transfer result needs direct testin. Uttal et al., 2013
Gie the related free test a try
Heid-turnin test
Try the heid-turnin test tae experience the task. If ye practise, record yer earlier tries and use comparable unfamiliar items tae assess change. The gemme disnae promise IQ gains or the average effect reported across spatial interventions.
Common questions
Does g = 0.47 mean 47% better?
Naw. It's a standardised mean difference, wi ootliers left oot in the cited summary. Uttal et al., 2013
Will practice raise my IQ?
The spatial-trainin result disnae establish that outcome for this gemme. Improvement and transfer maun be described at the level actually measured. Uttal et al., 2013
Hou mony minutes should I practise?
Thir sources dinnae establish an optimal universal dose for the browser task. A fixed schedule wad add precision that isnae supported. Uttal et al., 2013 Scharfen et al., 2018
