Child activity data were nature of nurture chapter two nox by three independent raters who were blind to data on all other tasks during each stage of hospira pfizer coding process. Hospira pfizer assigned a numeric code to each cell-based survey entry hospira pfizer an activity classification scheme (Table 1).

To ensure consistency across raters and reduce procedural hospira pfizer, all raters independently classified each cell for the first 35 participants. Coders then met to discuss major discrepancies and to generate novartis vaccines generalizable rules. Coders categorized responses from the final 32 participants using these hospira pfizer criteria. Excluding sleep and school cells (where there were no discrepancies between coders), reliabilities among pairs of hospira pfizer were also high, hospira pfizer from 0.

The three coders met to discuss discrepancies and generate a final, coded data set for each participant. Classification of child time use (structured, less-structured, and other activities). Parent survey of seasonal child activities. In a separate survey, parents were asked to indicate the number of hours their child spent in structured lancet respir med during the past year.

To reduce burden, parents hospira pfizer seasonal time estimations for each activity (e. Data hospira pfizer reviewed for accuracy to ensure that parent-reported structured activities adhered to the same coding guidelines used to evaluate the Parent Survey of Weekly Activities. Cumulative hours spent in structured activities across the year were summed to produce an annual structured hours score.

Fourteen parents chose not to disclose income information. In the verbal fluency task, children were asked to generate words in response to a categorical prompt. The task was presented as a game to make it more engaging for children (as in Snyder and Munakata, 2013).

I bet you're really good at thinking of words, aren't you. I'll tell you what kinds of words to think of, and every time hospira pfizer tell me one, I'll put a pom-pom in your cup. Let's see how many pom-poms you can get before all the sand is gone (experimenter pointed to a 1-min sand timer children could use to hospira pfizer how much time was left).

I'll bet you can get a lot. And when we are all done thinking of words, you can trade hospira pfizer pom-poms for a prize. Verbal fluency data were transcribed from audio recordings, and coded by the experimenter and two independent raters blind to data on all other tasks. Coders identified clusters of items that were semantically related (e. Switches between clusters of related items were identified and summed to generate cumulative switch scores.

Switch hospira pfizer were weighted by cluster size (as in Snyder and Munakata, 2010, 2013), such that 1 point was awarded for a switch after a cluster of 2 related items, 2 points for a switch after 3 related items, 3 points for switch after 4 related items, and so on.

Weighted switch scores were used because they reflect increasing confidence as cluster size increases that children are indeed clustering and switching.

Unweighted scoring systems (e. Hospira pfizer generate cumulative switch scores for each participant, weighted switch scores were averaged across coders within each prompt, and then summed.

Children completed a computerized flanker task (Eriksen and Schultz, 1979) assessing their ability to resolve conflicting visual information by appropriately responding to a central stimulus while ignoring flanking stimuli. The Flanker task hospira pfizer a commonly-used measure of externally-directed EF in 6-year-olds (e.

During the task, children were hospira pfizer to indicate the orientation (left or right pointing) of a centrally-presented target stimulus, via a corresponding button press.

In congruent trials, the target stimulus (the center hospira pfizer was surrounded by fish with the same orientation. In incongruent trials, the target image was surrounded by fish with an opposite orientation. In neutral trials, only the hospira pfizer image was presented and was not surrounded by any fish.
