Emotion colors time perception unconsciously

Emotion modulates our time perception. So far, the relationship between emotion and time perception has been examined with visible emotional stimuli. The present study investigated whether invisible emotional stimuli affected time perception. Using continuous flash suppression, which is a kind of dynamic interocular masking, supra-threshold emotional pictures were masked or unmasked depending on whether the retinal position of continuous flashes on one eye was consistent with that of the pictures on the other eye. Observers were asked to reproduce the perceived duration of a frame stimulus that was concurrently presented with a masked or unmasked emotional picture. As a result, negative emotional stimuli elongated the perceived duration of the frame stimulus in comparison with positive and neutral emotional stimuli, regardless of the visibility of emotional pictures. These results suggest that negative emotion unconsciously accelerates an internal clock, altering time perception.     

When violations of perfect duties do not cause strong trait attributions

It is well documented that violations of perfect duties (duties that can never be violated by moral agents) cause strong trait attributions. Brown, Trafimow, and Gregory (2005) found an exception to this general principle when the violation is performed under extreme circumstances. In the present research, we hypothesized that extreme circumstances are not necessary to weaken the attributional effect of violations of perfect duties provided that the violations were performed to help another person. Two experiments were performed in which target people violated perfect or imperfect duties for an unspecified reason or to help a third party. As expected, perfect duty violations did not result in strong trait attributions when they were performed to help someone, although they did result in strong trait attributions otherwise. Thus, the data support that the motive to help is sufficient to eliminate correspondent inferences to perfect duty violations.     

Visual discrimination in an orangutan (Pongo pygmaeus): measuring visual preference

Although previous studies have confirmed that trained orangutans visually discriminate between mammals and artificial objects, whether orangutans without operant conditioning can discriminate remains unknown. The visual discrimination ability in an orangutan (Pongo pygmaeus) with no experience in operant learning was examined using measures of visual preference. Sixteen color photographs of inanimate objects and of mammals with four legs were randomly presented to an orangutan. The results showed that the mean looking time at photographs of mammals with four legs was longer than that for inanimate objects, suggesting that the orangutan discriminated mammals with four legs from inanimate objects. The results implied that orangutans who have not experienced operant conditioning may possess the ability to discriminate visually.
