Altered Decision Behavior of Dopamine Receptor Knock-out Mice in a Free Binary Choice Task
… subtypes in reward-based learning, I examined choice behavior of dopamine D1 and D2 receptor-knockout (D1R-KO and D2R-KO, respectively) mice in an instrumental learning task with progressively increasing reversal frequency and in a dynamic foraging task. Performance of D2R-KO mice was …

The effects of learning intentions and choice task orientations on buyers' knowledge of price: an experimental investigation
… learning plans and the criteria they use pin choice decisions. Because of the differences in learning and choice task orientations, buyers are postulated to encode and store the information differently and therefore, different memory tests are necessary to investigate the retrieval mechanisms …

Cognitive dysfunction and schizophrenia : Modelling attentional impairment with psychotomimetics. Investigating attentional impairment and structural brain abnormalities following phencyclidine administration: Enhancing translatability between preclinical and clinical tests of attention utilising the modified 5-choice task in rats - the 5-Choice Continuous Performance Test.
… attentional impairment was tested, using the 5-choice serial reaction time task (5-CSRTT). The 5-CSRTT assesses not only visuospatial attention, but also components of impulsivity, compulsivity, speed of processing and motivation. It was determined that an additional task-related intervention …

A role for Dopamine neuron NMDA receptors in learning and decision-making
… learning, we developed an auditory-cued binary choice task using complex auditory stimuli that lend themselves to efficient learning as well as morphing. We report that mice lacking NMDARs in dopamine neurons have a deficit in learning an auditory two-alternative choice task, in the absence of …

Effects of choice and environmental control on the perception of control
… of this study was to investigate the effects of choice and environmental control on perceived control. A paired associate choice task was presented to all subjects and they were allowed to choose the response terms to be learned. When each of the response words was chosen aloud, the screen on …

Temporal Discounting: A comparison of adjusting-amount and adjusting-delay procedures
… were initially tested on one of the adjusting tasks: Adjusting Immediate Amount, Adjusting Delayed Amount, or Adjusting Delay) and returned a week later to complete each of the remaining adjusting tasks. The indifference points obtained from the initial adjusting task were used as the test …

Testing Tests: Determination of the Efficacy of Prejudice Measures
… Scale, Implicit Association Test and Seat Choice Task, none of the explicit measures correlated with the implicit measures. In addition, the implicit measures could not distinguish between target groups of blacks, females and a control group.</p>

An Investigation of English Structure Rules in Adult Learners of English as a Second Language
… in three test formats: a paired-comparison task, an isolated rating task, and a multiple-choice task. Contrastive analysis was used to hypothesize a sequence of acquisition for three pairs from among the selected errors. Eight three-way analyses of variance were performed with combined …

Syllabification and Visual Word Segmentation in Spanish–English Bilinguals
… syllabic intuitions a two-alternative forced choice task is used to gain insights about the initial syllables of CV and CVC trisyllabic words. A visual letter sequence monitoring task is utilized to investigate the use of a syllable-based segmentation strategy when processing Spanish. Support …

The amygdala in value-guided decision making
… making in rodents using an olfactory binary choice task. Using a logistic regression model, I show that the value of expected rewards is a strong influence on choice, and can bias perceptual decisions. In addition, I show that decisions are influenced by events in the near past, and a …

Timecourse of a perceptual judgment and factors affecting it
… The time taken to view the stimuli during these choices, termed processing time (PT), is an important quantity because it defines how informed, and thereby accurate, the choice is. Typically, the PT has been estimated from the reaction time (RT), which is the total amount of time taken to report …

Common or separate summary statistical processes for representing average and variance?
… the visual working memory. An odd-one-out search task was conducted to investigate this. 36 undergraduates in the University of Iceland took part in the experiment. At first they saw 36 stimuli, which were lines arranged in a 6x6 matrix for around three to four visual search trials and searched …

The perception of good and bad natural scene category exemplars
… Participants performed a two-alternative forced choice task in which they indicated whether an image was an intact or phase-scrambled scene photograph. In this task, observers were able to “see” good images better than bad scenes, more accurately detecting their brief presentations. This effect …

Control of intertemporal choice by dorsal raphe serotonergic neurons
… is often advantageous [2]. Appropriate choice about future rewards is critical for survival. The dorsal raphe serotonergic neurons have been long implicated in the control of temporal discounting of reward [3] [4], but it is not clear whether their activities in fact direct the decision …

The Non-Market Value of Biodiversity Enhancement in New Zealand's Planted Forests
… New Zealand’s planted forests using the stated choice experiments (CE) approach. This study focuses on two issues. One issue is policy orientated where we estimate the non-market value of biodiversity enhancement and the determinants of this value. The other issue is about the neutrality of …

Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences in Large and Small Dogs: Spatial Memory
… large and small dogs in a social cognition task where large dogs outperformed small dogs in a pointing choice task. Here I assessed the cognitive differences of large and small dogs using a series of spatial cognition tasks. As predicted there were no differences between large and small …

Investigating the Effects of Perceptual Complexity versus Conceptual Meaning on the Neural Correlates of Visual Working Memory
… (N = 22) performed a lateralized VWM task to test their memory of intact real-world objects, scrambled real-world objects and colours. The CDA was measured during perception and WM retention intervals (600-1000 ms and 1300-1700 ms post-stimulus onset, respectively), and behavioural …
