Verbatim and gist memory and individual differences in inhibition,sustained attention,and working memory capacity

In the present study, we explored whether individual differences in inhibition, sustained attention, and working memory capacity (WMC) are related to false memory task performance. We defined the processes in such a task according to the fuzzy trace theory and used multinomial modelling methodology to measure the contribution of these latent processes. We found higher verbatim memory in participants with a high WMC, as measured by the Rotation Span task, and in individuals who committed more errors in the Sustained Attention Response Task (SART). Participants with a high WMC and low-error level in SART showed higher gist memory for targets, and individuals high in WMC also rejected orthographically related distractors more effectively due to the recollection of distractors’ corresponding targets. We also observed that participants with better inhibition control were more conservative in guessing that an item was old.     

Language First: Deaf Children from Deaf Families Spontaneously Anticipate False Beliefs

ABSTRACT

Being connected to other people at the level of inner and unobservable mental states is one of the most essential aspects of a meaningful life, including psychological well-being and successful cooperation. The foundation for this kind of connectedness is our theory of mind (ToM), that is the ability to understand our own and others’ inner experiences in terms of mental states such as beliefs and desires. But how do we develop this ability? Forty-six 17- to 107-months-old children completed a non-verbal eye-tracker false-belief task. There were 9 signing deaf children from deaf families and two comparison groups, that is 13 deaf children with cochlear implants and 24 typically developing hearing children. We show that typically developing hearing children and deaf children from deaf families, but not deaf children with cochlear implants, succeeded on a non-verbal eye-tracking ToM task. The findings suggest that the ability to recognize others’ mental states is supported by very early, continuous and fluent language-based communication with caregivers.
