AbstractObjectives: Cognitive-linguistic impairments in Parkinson’s disease (PD) have been well documented; however, few studies have explored the neurophysiological underpinnings of semantic deficits in PD. This study investigated semantic function in PD using event-related potentials. Methods: Eighteen people with PD and 18 healthy controls performed a semantic judgement task on written word pairs that were either congruent or incongruent. Results: The mean amplitude of the N400 for new incongruent word pairs was similar for both groups, however the onset latency was delayed in the PD group. Further analysis of the data revealed that both groups demonstrated attenuation of the N400 for repeated incongruent trials, as well as attenuation of the P600 component for repeated congruent trials. Conclusions: The presence of N400 congruity and N400 repetition effects in the PD group suggests that semantic processing is generally intact, but with a slower time course as evidenced by the delayed N400. Additional research will be required to determine whether N400 and P600 repetition effects are sensitive to further cognitive decline in PD. (JINS, 2017, 23, 78–89)

Unfamiliar Faces

The effects of configural changes on faces were investigated in children to determine their role in encoding and recognition processes. Upright, inverted, and contrast-reversed unfamiliar faces were presented in blocks in which one-third of the pictures repeated immediately or after one intervening face. Subjects (8–16 years) responded to repeated faces; eventrelated potentials were recorded throughout the procedure. Recognition improved steadily with age and all components studied showed age effects reflecting differing maturation processes occurring until adulthood. All children were affected by inversion and contrast-reversal, and face-type effects were seen on latencies and amplitudes of early components (P1 and N170), as well as on later frontal amplitudes. The “old-new” repetition effects (larger amplitude for repeated stimuli) were found at frontal sites and were similar across age groups and face types, suggesting a general working memory system comparably involved in all age groups. These data demonstrate that (1) there is quantitative development in face processing, (2) both face encoding and recognition improve with age, but (3) only encoding is affected by configural changes. The data also suggest a gradual tuning of face processing towards the upright orientation.

Unfamiliar Faces

Individual abilities in face recognition (good versus bad recognizers) were explored by means of event-related potentials (ERPs). The adaptation response profile of the N170 component to whole faces, eyes and mouths was used in order to highlight the crucial role of individual abilities in identity repetition processes for unfamiliar faces. The main point of this study is to underline the importance of characterizing the performance (bad or good) of the participants and to show that behaviorally selected groups might reveal neural differences. Good recognizers showed selective right hemisphere N170 repetition effects for whole faces and not for features. On the contrary, bad recognizers showed a general repetition effect not specifically related to faces and more pronounced processing for features. These findings suggest a different contribution of holistic and featural analysis in bad and good performers. In conclusion, we propose that the N170 might be used as a tool to tease apart face encoding processes as a function of individual differences.

AbstractRepeated exposure to a stimulus leads to reduced responses of stimulus-selective sensory neurons, an effect known as repetition suppression or stimulus-specific adaptation. Several influential models have been proposed to explain repetition suppression within hierarchically-organised sensory systems, with each specifying different mechanisms underlying repetition effects. We manipulated temporal expectations within a face repetition experiment to test a critical prediction of the predictive coding model of repetition suppression: that repetition effects will be larger following stimuli that appear at expected times compared to stimuli that appear at unexpected times. We recorded event-related potentials from 18 participants and mapped the spatiotemporal progression of repetition effects using mass univariate analyses. We then assessed whether the magnitudes of observed face image repetition effects were influenced by temporal expectations. In each trial participants saw an adapter face, followed by a 500ms or 1000ms interstimulus interval (ISI), and then a test face, which was the same or a different face identity to the adapter. Participants’ expectations for whether the test face would appear after a 500ms ISI were cued by the sex of the adapter face. Our analyses revealed multiple repetition effects with distinct scalp topographies, extending until at least 800ms from stimulus onset. An early (158-203ms) repetition effect was larger for stimuli following surprising, rather than expected, 500ms ISI durations, contrary to the model predictions of the predictive coding model of repetition suppression. Later (230-609ms) repetition effects tended to be larger following expected stimulus onset times, in line with predictive coding models. Our results indicate that the relationship between repetition suppression and temporal expectation differs across the time course of the stimulus-evoked response, suggesting multiple distinct mechanisms driving repetition suppression that operate at different latencies within the visual hierarchy.Highlights- Multiple face image repetition effects identified from 162-800ms post stimulus onset- Temporal expectations influenced the magnitudes of repetition effects- Temporal expectation effects differed for early and late stimulus-evoked responses

Distractor-to-distractor repetition effects can be explained by retrieval and/or inhibitory processes. Interestingly, the two accounts predict different effects from repeated distractors: Inhibition theories always predict benefits, whereas stimulus-response-retrieval theories predict an interaction of response repetition and distractor repetitions, resulting in benefits with response repetitions and costs with response changes. In the present experiment the time-course and the temporal separability of a stimulus-response episode on distractor-to-distractor repetitions were analyzed. The results showed that the interaction of response repetition and distractor repetitions was affected by a simple decay function. In addition, distractor repetition effects were affected by the temporal separability. In concert, the data yield evidence for retrieval-based explanations of distractor-to-distractor repetitions.

Prior exposure to a stimulus can facilitate the performance to subsequent presentations of that stimulus. ERP studies have shown that this facilitation is associated with the modulation of two components (N400 and P600). Investigation of the time course of both behavioral and ERP repetition effects have led to the assumption that it is subserved by the combination of at least two mechanisms operating at different time-points: a short-delay semantic activation and a long-lasting episodic mechanism. The present experiment recorded intracranial ERPs from various structures during a continuous recognition memory task to investigate the respective contribution of the different brain regions to short-and long-delay ERP repetition effects. The results are in good agreement with both the classical neuropsychological literature and the more recent data obtained with functional imagery techniques. They provide electrophysiological evidence of multiple anatomo-functional memory systems in the human brain: a short-term semantic activation system and a long-term episodic memory system, with interface structures that coordinate the functioning of these two systems.
