Despite the importance of attentive processes in learning,there is a dearth of findings on the relationship betweenattentiveness and academic performance amongst nonclinicalsamples. Of those that are available, most tendedto utilize teachers' ratings (e.g., Merrell & Tymrns, 2001).Although such ratings may serve as one indicator ofattentiveness, they are likely to be based on behaviouralmanifestation of attentiveness. <strong>The</strong> risk is that less visibledifferences in attentiveness are neglected.Figure 1This paper presents some preliminary data on individualdifferences in attentionalefficiency and its relationshipwithEnglish performance. A children's version of the attentionalnetwork test (ANT, Fan et al., 2002) was used. Thiscomputerisedtest combines the cue reaction time and theflanker tasks used in previous studies(see Figure 1). It yieldsthree indexes designed to measure the efficiency of thealerting, orienting, and conflict resolution networks.MethodParticipantsEighty-eight primary 3 children participated in theexperiment. <strong>The</strong> sample was recruited from a governmentschool in Singapore and contained about the same numberof boys and girls. <strong>The</strong> children participated with informedconsent from their parents.Instruments and ProcedureEnglishperformance. A written test which comprised itemson grammar, vocabulary, phonology, readingcomprehension, and composition was used. Content of thetest was drawn from curriculum material that had not beentaught explicitly in class.Affentional Network Testlhe ANT contained 24 individuallyadministeredpracticetrials and 144 test trials. Within eachtrial, children were presented with a row of one or morefish (see Figure 1 ). <strong>The</strong> target was the fish in the middk. Itfaced either the left or the right hand side of the screen.Children had to identify whether the fish was facing left orright by pressing the appropriate button on a mouse.<strong>The</strong>re were 12 types of test trials, formed by a full factorialmanipulation of two variables: flanker type (neutral,congruent, and incongruent) or cue type [none, centre,double, and orienting). In the neutraI condition, the targetfish appeared by itself. In the congruent and incongruentconditions, the fish was flanked on either side by fish facingthe same or the opposite direction respectively. In 75% oftrials, appearance of the fish was cued by an asterisk. <strong>The</strong>cue provided either no information on where the fish wasto appear (in the middle or doublecue conditions) or explicitinformation on whether it was to appear above or belowthe fixation point (in the orienting condition).ScoringThree indexes were generated using subtractions from Fanet a[. (2002).Alerting = RT (all no-cue trials) - RT (all double cue trials) Orienting = RT (centre cue) - RT (orienting cue) Conflict = RT (incongruent)- RT (incongruent)ResultsOne child failed to complete the procedure and data fromtwo children were found to be multivariate outliers. <strong>The</strong>sedata were excluded from the analyses. To examine there[ationship between attentional efficiency and Englishdata from the two variables were analy& ina standard regression. Reaction time and accuracy scorefrom the various ANT conditions were analysed in a doublymultivariate analysis of variance.Regression analysisInter-correlation between the three indexes revealed littleinter-dependence (seeTable 1).<strong>The</strong> three indexes predictedreliably to English performance and accounted for 130hofits variance. Of the three indexes, only aterting efficiencyprovided significant contribution.Table 1Summaty of Standard RegressionAnalysis for VariablesPredicting to English Performance (EP)Variables OR A1 EP 5 SEB BOrienting (OR) - - 1-03 .01 .2OSAlerting (AL) -.05 - .23* -03 -01 .27*.,Conflict (CF) .01 .03 -.I5 -.02 .O1 -.I9Note.R=.36, RZ=.13,p= .01;*p
