Journal Article
van Heuven, W. J., Conklin, K., Coderre, E. L., Guo, T., & Dijkstra, T. (2011). The influence of cross-language similarity on within- and between-language Stroop effects in trilinguals. Frontiers in Psychology, 2(374), Article 374. https://doi.org/10.3389/fpsyg.2011.00374

This study investigated effects of cross-language similarity on within- and between-language Stroop interference and facilitation in three groups of trilinguals. Trilinguals were either proficient in three languages that use the same-script (alphabet...

Neuronal signals for reward risk in frontal cortex: Risky reward signals (2011)
Journal Article
O’Neill, M., Tobler, P. N., Kobayashi, S., & Schultz, W. (2011). Neuronal signals for reward risk in frontal cortex: Risky reward signals. Annals of the New York Academy of Sciences, 1239(1), 109-117. https://doi.org/10.1111/j.1749-6632.2011.06256.x

Rewards can be viewed as probability distributions of reward values. Besides expected (mean) value, a key parameter of such distributions is variance (or standard deviation), which constitutes a measure of risk. Single neurons in orbitofrontal cortex...

Fluctuations in the open time of synaptic channels: an application to noise analysis based on charge (2011)
Journal Article
Feldwisch-Drentrup, H., Barrett, A. B., Smith, M. T., & van Rossum, M. C. (2012). Fluctuations in the open time of synaptic channels: an application to noise analysis based on charge. Journal of Neuroscience Methods, 210(1), https://doi.org/10.1016/j.jneumeth.2011.11.004

Synaptic channels are stochastic devices. Even recording from large ensembles of channels, the fluctuations, described by Markov transition matrices, can be used to extract single channel properties. Here we study fluctuations in the open time of cha... Read More about Fluctuations in the open time of synaptic channels: an application to noise analysis based on charge.

Dendritic spine dynamics regulate the long-term stability of synaptic plasticity (2011)
Journal Article
O'Donnell, C., Nolan, M. F., & van Rossum, M. C. (2011). Dendritic spine dynamics regulate the long-term stability of synaptic plasticity. Journal of Neuroscience, 31(45), https://doi.org/10.1523/JNEUROSCI.2520-11.2011

Long-term synaptic plasticity requires postsynaptic influx of Ca²⁺ and is accompanied by changes in dendritic spine size. Unless Ca²⁺ influx mechanisms and spine volume scale proportionally, changes in spine size will modify spine Ca²⁺ concentrations...

Inner speech during silent reading reflects the reader's regional accent (2011)
Journal Article
Filik, R., & Barber, E. (2011). Inner speech during silent reading reflects the reader's regional accent. PLoS ONE, 6(10), Article e25782. https://doi.org/10.1371/journal.pone.0025782

While reading silently, we often have the subjective experience of inner speech. However, there is currently little evidence regarding whether this inner voice resembles our own voice while we are speaking out loud. To investigate this issue, we comp...

The pattern of learned visual improvements in adult amblyopia (2011)
Journal Article
Astle, A. T., Webb, B. S., & McGraw, P. V. (2011). The pattern of learned visual improvements in adult amblyopia. Investigative Ophthalmology & Visual Science, 52(10), https://doi.org/10.1167/iovs.11-7584

Purpose. Although amblyopia is diagnosed in terms of a monocular letter acuity loss, individuals typically present with deficits on a wide range of spatial tasks. Many of these deficits can be collapsed along two basic visual dimensions (visual acuit... Read More about The pattern of learned visual improvements in adult amblyopia.

A clozapine-like effect of cyproheptadine on progressive ratio schedule performance (2011)
Journal Article
Olarte-Sánchez, C., Valencia Torres, L., Cassaday, H. J., Body, S., Bradshaw, C., Szabadi, E., & Goudie, A. (2012). A clozapine-like effect of cyproheptadine on progressive ratio schedule performance. Journal of Psychopharmacology, 26(6), 857-870. https://doi.org/10.1177/0269881111408961

The atypical antipsychotic drug clozapine has multiple pharmacological actions, some of which, including 5-hydroxytryptamine (5-HT2) and histamine (H1) receptor antagonist effects, are shared by the non-selective 5-HT receptor antagonist cyproheptadi...

Scalable reinforcement learning through hierarchical decompositions for weakly-coupled problems (2011)
Presentation / Conference Contribution
Toutounji, H., Rothkopf, C. A., & Triesch, J. (2011, August). Scalable reinforcement learning through hierarchical decompositions for weakly-coupled problems. Presented at 2011 IEEE International Conference on Development and Learning (ICDL), Frankfurt am Main, Germany

Reinforcement Learning, or Reward-Dependent Learning, has been very successful at describing how animals and humans adjust their actions so as to increase their gains and reduce their losses in a wide variety of tasks. Empirical studies have furtherm... Read More about Scalable reinforcement learning through hierarchical decompositions for weakly-coupled problems.

Can human amblyopia be treated in adulthood? (2011)
Journal Article
Astle, A. T., McGraw, P. V., & Webb, B. S. (in press). Can human amblyopia be treated in adulthood?. Strabismus, 19(3), https://doi.org/10.3109/09273972.2011.600420

Amblyopia is a common visual disorder that results in a spatial acuity deficit in the affected eye. Orthodox treatment is to occlude the unaffected eye for lengthy periods, largely determined by the severity of the visual deficit at diagnosis. Althou...

Impulsivity and symptoms of nicotine dependence in a young adult population (2011)
Journal Article
Chase, H. W., & Hogarth, L. (2011). Impulsivity and symptoms of nicotine dependence in a young adult population. Nicotine & Tobacco Research, 13(12), https://doi.org/10.1093/ntr/ntr114

Introduction:

Impulsivity is widely regarded as a risk factor for drug dependence. However, its relationship with the symptomatology of nicotine dependence is poorly understood.

Methods:

To examine the nature of these relationships, we recru... Read More about Impulsivity and symptoms of nicotine dependence in a young adult population.
