Young infants' visual fixation patterns in addition and subtraction tasks support an object tracking account.

Investigating infants' numerical ability is crucial to identifying the developmental origins of numeracy. Wynn (1992) claimed that 5-month-old infants understand addition and subtraction as indicated by longer looking at outcomes that violate numerical operations (i.e.

The role of perceptual and cognitive processes in addition-subtraction studies with 5-month-old infants.

After a brief familiarization period to either one or two toys 5-month-olds gave a clear preference for perceptually novel displays, suggesting that replicable findings of greater looking at an unexpected arithmetic outcome in addition/subtraction experiments cannot easily be attributed to simple familiarity preferences.

Collaborative Depression Trial (CADET): multi-centre randomised controlled trial of collaborative care for depression--study protocol.

Background: Comprising of both organisational and patient level components, collaborative care is a potentially powerful intervention for improving depression treatment in UK primary Care. However, as previous models have been developed and evaluated in the United States, it is necessary to establish the effect of collaborative care in the UK in order to determine whether this innovative treatment model can replicate benefits for patients outside the US. This Phase III trial was preceded by a Phase II patient level RCT, following the MRC Complex Intervention Framework.

Three-month-olds' detection of alliteration in syllables.

Using an auditory-preference procedure we found that 3-month-olds listened significantly longer to alliterative CVCs than to non-alliterative CVCs. This finding demonstrates that 3-month-olds are sensitive to syllable onsets and is discussed in relation to early speech perception and similar results found with 9-month-olds [Jusczyk, P. W.
