A comparison of techniques for measuring hue appearance

Three different techniques for the direct measurement of color appearance were studied. Color estimation proved superior both to color naming and to color setting. The results have defined one technique in generating a color metric.     

Reviews,expectations, and the experience of stories

ABSTRACT

Theory suggests that information encountered prior to a story affects the actual experience of the story due to elicited expectations. In two experiments (N = 100; N = 167) short movies that were introduced with a positive review yielded higher transportation scores than the same movies introduced with a more negative (or neutral) review. Mediation analyses indicate that the reviews had an influence on recipients’ expectations, which in turn predicted the experience of the movie. Using the more fine-grained narrative engagement scale, we found evidence for a consistent effect on narrative presence, whereas the influence on emotional engagement, narrative understanding, and attentional focus varied between experiments. Moderation analyses (moderated mediation) showed that recipient’s opinion seeking and need for cognitive closure were unrelated to the influence of reviews on expectations and the link between expectations and narrative experience. Our findings add to the theory of story processing and they are of practical relevance for everyone who intends to influence recipients’ experience of narrative worlds.     

Children’s prior experiences of their successes and failures modulate belief alignment

ABSTRACT

An ability to flexibly learn from others while at other times relying upon one’s own judgements is an important adaptive human capacity. The present research investigated how others’ epistemic states and prior experience of their own independent ability in a given task modulate young children’s selective learning. In particular, we asked whether 4-year-old children’s judgement concerning the location of a hidden object is modulated both by an informant’s knowledge states and by the absence/presence of a prior experience with a particular task. We found that the children were more likely to align their judgement according to the informant’s verbal report when the informant was knowledgeable than when she was ignorant – but only when they had explicitly experienced their own incapability to accurately guess an object’s location. The findings suggest that 4-year-old children are able to combine their own experience with others’ input to make their judgement.     

Gender Differences in Moral Influences on Adolescents’ Eyewitness Identification

Abstract

In this study, 232 (89 11- to 12-year-olds, 71 13- to 14-year-olds; 72 15- to 16-year-olds) students recruited from grades 6th–11th in an urban public high school participated in a study of eyewitness identification. The focus of this study was on the effects of age, gender and moral orientation on decisional bias and, as a secondary outcome, on accuracy (using signal detection analysis).The primary purpose of this and previous studies in this series is to uncover implicit moral decision-making in decisional bias. In this study the perpetrator, the bystanders and the foil were all females. Prior to completing the eyewitness identification task, participants were given instructions that emphasized either (a) fairness and crime prevention, or (b) neither. These instructions had no discernible effect on accuracy but, as in past studies, younger participants (below the age of 13) had lower decisional criteria, resulting in a higher rate of false alarms/positives. Further, those who judged the transgression as worse had a lower decisional criterion, indicating more false alarms. Females were more accurate than the males in identifying the female perpetrator and scored significantly higher on how bad they would feel if they were the victim than did the males.
