How to get SharePoint list field value of type person or group using ecmascript or SPServices?

Following is my code…

function retrieveListItems() {
    var clientContext = new SP.ClientContext(siteUrl);
    var oList = clientContext.get_web().get_lists().getByTitle('list name');
    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml('<View><Query><Where><Eq><FieldRef Name=\'ID\'/>' + < Value Type = \'Integer\'>413</Value></Eq></Where></Query></View>');
    this.collListItem = oList.getItems(camlQuery);
    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));

function onQuerySucceeded(sender, args) {
    var listItemInfo = '';
    var listItemEnumerator = collListItem.getEnumerator();
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
        listItemInfo += 'Title: ' + oListItem.get_item('Writer').get_lookupValue();

function onQueryFailed(sender, args) {
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());

I even tried with oListItem.get_item('Writer').get_title() but it is not working..
Sometime it returns undefined…
Please help..

    If you are looking for list item ‘Created By’ value then use ‘Author’ instead of ‘Writer’ or if you want ‘Modified By’ value then use ‘Editor’ instead of ‘Writer’.
