Opis:
The anchoring heuristic refers to phenomena when an arbitrary number affects subsequent numerical estimations. Oppenheimer, LeBoeuf and Brewer (2008) showed that it is not necessary for the anchor to be a numerical value (i.e., the act of drawing lines of different length effectively shifts numerical estimations), yet current models describing the anchoring heuristic do not fully account for the mechanism of non-numerical anchoring. However, this effect shows similarity to the basic anchoring effect – obtained without the comparative question and based on the availability of the given number in working memory. In this study, we attempt to verify whether those two effect share the same psychological mechanism. In Experiment 1, we show that non-numerical anchoring based on magnitude priming cannot be obtained when the lines are just observed. The examined mechanism proves to be dependent on the act of drawing, displaying limitations similar to the basic anchoring effect, previously pointed out by Brewer and Chapman (2002). By using the same numerical anchors in different size formats, in Experiment 2 we showed that anchoring based on magnitude priming occurs even when the numerical values do not affect the estimations. The results are discussed in the light of a possible mechanism that underlies the investigated effect.

Opis:
An implicit memory advantage for angry faces was investigated in this experiment by means of an additional cueing task. Participants were to assess the orientation of a triangle's peak, which side of presentation was cued informatively by angry and neutral face stimuli, after which they immediately completed an unexpected “old-new” task on a set of the previously presented faces and new, distractor-faces. Surprisingly, the RTs were similarly long on the invalid trials for angry and neutral facial cues in the Posner task. However, performance on the “old-new” task was better for angry than neutral faces. A strong correlation between RTs in angry-invalid trials and confidence ratings for these angry faces was observed only in highly reactive participants. These results suggest that presentation of threatening material can induce enhanced incidental encoding which can result in stronger familiarity for such material, and this effect is driven by attentional bias in highly reactive individuals.
