Snakes were probably the first predators of mammals and may have been important agents of evolutionary changes in the primate visual system allowing rapid visual detection of fearful stimuli (Isbell, 2006). By means of early and late attention-related brain potentials, we examined the hypothesis that more early visual attention is automatically allocated to snakes than to spiders. To measure th...

In the part-set cuing effect, cuing a subset of previously studied items impairs recall of the remaining noncued items. This experiment reveals that cuing participants with previously-studied emotional pictures (e.g., fear-evoking pictures of people) can impair recall of pictures involving the same emotion but different content (e.g., fear-evoking pictures of animals). This indicates that new e...

The effects of differences in study processing on free recall of picture names and on generalization in picture identification were investigated. Experience with degraded pictures produced poorer subsequent free recall of picture names than did naming intact pictures. For the test of picture identification, pictures that were identical to a studied picture, pictures that shared a name with a st...

The studyforrest (http://studyforrest.org) dataset is likely the largest neuroimaging dataset on natural language and story processing publicly available today. In this article, along with a companion publication, we present an update of this dataset that extends its scope to vision and multi-sensory research. 15 participants of the original cohort volunteered for a series of additional studies...

The growth of Internet-based piracy has led to a wide-ranging debate over how copyright policy should be enforced in the digital era. In this paper we analyze the impact of the US government’s shutdown of a major piracy site — Megaupload.com — on digital sales and rentals of movies. Exploiting cross-country variation in pre-shutdown usage of Megaupload, we find that the shutdown of Megaupload a...

the pictures of the textbooks play an important role in the transfer of conceptsand values to students. however, no comprehensive studies have been done onthe functions of pictures and their effects on the students from the genderperspective in the instructional language textbooks in iran. accordingly, thecurrent study is an attempt to evaluate the pictures in iranian high-schoolenglish textboo...

Responding to pro-social cues plays an important adaptive role in humans. Our aims were (i) to create a catalog of bonding and matched-control pictures to compare the emotional reports of valence and arousal with the International Affective Picture System (IAPS) pictures; (ii) to verify sex influence on the valence and arousal of bonding and matched-control pictures; (iii) to investigate if emp...
