Declarative memory, awareness, and transitive inference.
A characteristic usually attributed to declarative memory is that what is learned is accessible to awareness. Recently, the relationship between awareness and declarative (hippocampus-dependent) memory has been questioned on the basis of findings from transitive inference tasks. In transitive inference, participants are first trained on overlapping pairs of items (e.g., A+B-, B+C-, C+D-, and D+...
متن کاملThe role of awareness and working memory in human transitive inference.
The human ability to perform transitive inference (TI) is an area of debate from a neurocognitive standpoint. Some studies emphasize a stimulus driven medial-temporal lobe process [Preston, A.R., Shrager, Y., Dudukovic, N.M., Gabrieli, J.D., 2004. Hippocampal contribution to the novel use of relational information in declarative memory. Hippocampus 14, 148-152; Titone, D., Ditman, T., Holzman, ...
متن کاملTransitive inference in schizophrenia: impairments in relational memory organization.
Transitive inference (TI) describes a fundamental operation of relational (e.g., explicit) memory organization [Eichenbaum, H., Cohen, N.J., 2001. From Conditioning to Conscious Recollection: Memory Systems of the Brain. Oxford Univ. Press]. Here we investigate TI in schizophrenia (SZ), a neurocognitive disorder associated with explicit but not implicit memory dysfunction. SZ patients and healt...
متن کاملRelational learning with and without awareness: transitive inference using nonverbal stimuli in humans.
Learning complex relationships among items and representing them flexibly have been shown to be highly similar in function and structure to conscious forms of learning. However, it is unclear whether conscious learning is essential for the exhibition of flexibility in learning. Successful performance on the transitive inference task requires representational flexibility. Participants learned fo...
متن کاملLifted Inference on Transitive Relations
Lifted inference algorithms are able to boost efficiency through exploiting symmetries of the underling firstorder probabilistic models. Models with transitive relations (e.g., if X and Y are friends and so are Y and Z, then X and Z will likely be friends) are essential in social network analysis. With n elements in a transitive relation model, the computational complexity of exact propositiona...
