Simultaneous storage of two complex temporal sound patterns in auditory sensory memory.

We wished to determine whether multiple sound patterns can be simultaneously represented in the temporary auditory buffer (auditory sensory memory), when subjects have no task related to the sounds. To this end we used the mismatch negativity (MMN) ...

Abstract phoneme representations in the left temporal cortex: magnetic mismatch negativity study.

We investigated the brain mechanisms enabling one automatically discriminate phoneme category irrespective of the large inter-speaker variability in the acoustic features of the voices. For this purpose, subjects were presented with 450 different speech ...

Brain activity underlying encoding and retrieval of source memory.

Neural activity elicited during the encoding and retrieval of source information was investigated with event-related functional magnetic resonance imaging (efMRI). During encoding, 17 subjects performed a natural/artificial judgement on pictures of ...

Memory for recent eating and its influence on subsequent food intake.

The effect of being reminded of a recent eating episode on subsequent food intake was examined in unrestrained eaters. In Experiment 1, female participants were exposed to a "lunch cue" (in which they were asked to think about what they had eaten for ...

Mistaken memories: remembering events that never happened.

Our memories can be accurate, but they are not always accurate. Eyewitness testimony, for example, is notoriously unreliable. Insights into both veridical and false remembering have come from recent investigations of memory distortion. Behavioral ...

Does a prosocial-selfish distinction help explain the biological affects? Comment on Buck (1999).

R. Buck (1999) argued that a conceptual distinction between prosocial and selfish motivation is necessary to understand the biological affects (consciously experienced feelings and desires having an innate neurochemical basis). However, at a biological ...

Models of functional organization of the lateral prefrontal cortex in verbal working memory: evidence in favor of the process model.

Research on the functional organization of the lateral prefrontal cortex (PFC) in working memory continues to be fairly equivocal between two major frameworks: organization-by-process or organization-by-material. Although there is fairly strong evidence ...

Simple adaptive strategy wins the prisoners dilemma.

The prisoners dilemma has become the leading paradigm to explain the evolution of cooperation among selfish individuals. Here, we present an adaptive strategy that implements new mechanisms to process information about past encounters. The history of ...

Presentation format and its effect on working memory.

In three experiments, we examined the separate cognitive demands of processing and storage in working memory and looked at how effective the coordination was when items for storage varied in format/modality. A sentence verification task involving ...

Concurrent performance of two memory tasks: evidence for domain-specific working memory systems.

Previous studies of dual-task coordination in working memory have shown a lack of dual-task interference when a verbal memory task is combined with concurrent perceptuomotor tracking. Two experiments are reported in which participants were required to ...
