Abstract

The information we obtain from how speakers sound—for example their accent—affects how we interpret the messages they convey. A clear example is foreign accented speech, where reduced intelligibility and speaker's social categorization (out-group member) affect memory and the credibility of the message (e.g., less trustworthiness). In the present study, we go one step further and ask whether evaluations of messages are also affected by regional accents—accents from a different region than the listener. In the current study, we report results from three experiments on immediate memory recognition and immediate credibility assessments as well as the illusory truth effect. These revealed no differences between messages conveyed in local—from the same region as the participant—and regional accents—from native speakers of a different country than the participants. Our results suggest that when the accent of a speaker has high intelligibility, social categorization by accent does not seem to negatively affect how we treat the speakers' messages.

The information we obtain from how speakers sound—for example their accent—affects how we interpret the
messages they convey. A clear example is foreign accented speech, where reduced intelligibility and speaker's
social categorization (out-group member) affect memory and the credibility of the message (e.g., less trust-
worthiness). In the present study, we go one step further and ask whether evaluations of messages are also
affected by regional accents—accents from a different region than the listener. In the current study, we report
results from three experiments on immediate memory recognition and immediate credibility assessments as well

Abstract

We examined side preferences in the Florida manatee (Trichechus manatus latirostris) through observations of limb use (right and left flipper) in 123 wild and 16 captive individuals. We also analyzed archival data, the United States Geological Survey Sirenia ProjectManatee Individual Photo-identification Systemdataset, to determine lateralization of evasive action from boats. Wild and captive manatees displayed flipper lateralization at the individual, but not the population level for several behaviors including substrate touches, sculling, and feeding. In contrast, manatees were lateralized at the population level for boat-scar biases,with more manatees showing a left scar bias (45.3%) versus right (34.3%) or dorsal/ambipreferent (20.3%).

Abstract

he current study examined the interaction of fearful, angry,
happy, and neutral expressions with left, straight, and
right eye gaze directions. Human participants viewed
faces consisting of various expression and eye gaze
combinations while event-related potential (ERP) data
were collected. The results showed that angry expressions
modulated the mean amplitude of the P1, whereas fearful
and happy expressions modulated the mean amplitude of
the N170. No influence of eye gaze on mean amplitudes for
the P1 and N170 emerged. Fearful, angry, and happy
expressions began to interact with eye gaze to influence
mean amplitudes in the time window of 200–400 ms.
The results suggest early processing of expression
influence ERPs independent of eye gaze, whereas
expression and gaze interact to influence later
ERPs.
