‘The Queen Mother and I’: assimilation,contrast, and attitudes toward social groups

We examined whether social group attitudes are subject to context effects. It was hypothesised that manipulating the context in which a group exemplar was rendered accessible would produce different effects when subjects were subsequently asked to evaluate the exemplar's group. In our study, all subjects first expressed their opinion about the (popular) Queen Mother before indicating their attitude toward the British Royal Family. In the ‘non‐redundant’ condition, the two questions were structured such that the Queen Mother was expected to be included in individuals' representation of the Royal Family, leading to a high correlation between the two judgements and a favourable evaluation of the group. Conversely, in the ‘redundant’ condition, the questions were structured such that the Queen Mother was expected to be excluded from individuals' representation of the Royal Family, leading to a lower correlation between the judgements and a less favourable evaluation of the group. The results supported the hypothesis, and are consistent with the Schwarz and Bless (1992a,b) inclusion/exclusion model of assimilation and contrast. Copyright © 1999 John Wiley & Sons, Ltd.     

Right and Righteous: Children's Incipient Understanding and Evaluation of True and False Statements

Two studies examined young children's early understanding and evaluation of truth telling and lying and the role that factuality plays in their judgments. Study 1 (one hundred four 2- to 5-year-olds) found that even the youngest children reliably accepted true statements and rejected false statements and that older children's ability to label true and false (T/F) statements as “truth” and “lie” emerged in tandem with their positive evaluation of true statements and “truth” and their negative evaluation of false statements and “lie.” The findings suggest that children's early preference for factuality develops into a conception of “truth” and “lie” that is linked both to factuality and moral evaluation. Study 2 (one hundred twenty-eight 3- to 5-year-olds) revealed that whereas young children exhibited good understanding of the association of T/F statements with “truth,” “lie,” “mistake,” “right,” and “wrong,” they showed little awareness of assumptions about speaker knowledge underlying “lie” and “mistake.” The results further support the primacy of factuality in children's early understanding and evaluation of truth and lies.     

Age differences in what is viewed and remembered in complex conjunction search

Older and younger adults searched arrays of 12 unique real-world photographs for a specified object (e.g., a yellow drill) among distractors (e.g., yellow telephone, red drill, and green door). Eye-tracking data from 24 of 48 participants in each age group showed generally similar search patterns for the younger and older adults but there were some interesting differences. Older adults processed all the items in the arrays more slowly than the younger adults (e.g., they had longer fixation durations, gaze durations, and total times), but this difference was exaggerated for target items. We also found that older and younger adults differed in the sequence in which objects were searched, with younger adults fixating the target objects earlier in the trial than older adults. Despite the relatively longer fixation times on the targets (in comparison to the distractors) for older adults, a surprise visual recognition test revealed a sizeable age deficit for target memory but, importantly, no age differences for distractor memory.     

Stroop interference, practice, and aging

We report two experiments that investigate practice effects on Stroop color-word interference in older and younger adults. Both experiments employed a computerized, single-item version of the Stroop task with a voice response, and both involved practice over hundreds of trials. Both experiments showed generally similar practice patterns, including a practice-related reduction in the size of the color-word interference effect. However, the older group continued to show a larger interference effect throughout practice. These findings indicate that older adults show the same trend in practice-related improvement on the Stroop task as younger adults.
