Choice selection and reward anticipation: an fMRI study
Neuropsychologia, 2004We examined neural activations during decision-making using fMRI paired with the wheel of fortune task, a newly developed two-choice decision-making task with probabilistic monetary gains. In particular, we assessed the impact of high-reward/risk events relative to low-reward/risk events on neural activations during choice selection and during reward ...

Diminished choice effect on anticipating improbable rewards
Neuropsychologia, 2018Previous research found that the neural substrates underlying perceived control highly overlap those of reward system, especially during reward anticipation stage. The current event-related potential study examined whether the experience of choice by which individuals exercise control is modulated by reward probability during reward anticipation stage ...

Role of anticipated reward in cognitive behavioral control
Current Opinion in Neurobiology, 2007The lateral prefrontal cortex (LPFC), which is important for higher cognitive activity, is also concerned with motivational operations; this is exemplified by its activity in relation to expectancy of rewards. In the LPFC, motivational information is integrated with cognitive information, as demonstrated by the enhancement of working-memory-related ...

Frontostriatal Connectivity During Reward Anticipation
Zeitschrift für Psychologie, 2017Abstract. Neurobiological research indicates that altered reward processing is among the most promising risk mechanisms in alcohol use disorder and depression. To elucidate differences and similarities between both disorders, we investigated clinical patients and at-risk individuals in two studies using a functional magnetic resonance imaging (fMRI ...

ANTICIPATED REWARD IN OBSESSIVE-COMPULSIVE DISORDER
European Neuropsychopharmacology, 2016abstract Introduction The affective state that occurs during the anticipation of a behavior is typically associated with the expected outcomes of that behavior [1] . This notion is relevant for compulsive behaviors in obsessive compulsive disorder (OCD), which is characterized by a deficit in using accurate models of prospective action-outcome ...

Anticipated Reward and Time Estimation in Young Navajo Children
Perceptual and Motor Skills, 1978Time estimations of 1-min. intervals using the method of reproduction by 112 Navajo children were measured under neutral and reward conditions in a repeated-measures design. Anticipated reward (a piece of candy) significantly reduced the accuracy of time estimations.

Reward-quality dependent anticipation in rat nucleus accumbens
NeuroReport, 1998Single unit recording in rat nucleus accumbens (NAcc) was used to ascertain NAcc neuronal activity in mediating of reward including its anticipation. Of the 103 neurons investigated, 63% showed some response in connection with the task activity. Of these, 20 units responded during delivery of the primary reward (food and/or water) and five responded ...
