Mapping the time-course and content of visual predictions with a novel object-scene associative memory paradigm
… of contextual facilitation effects in visual object processing. In all three experiments, participants studied novel object-scene pairs in a paired associate memory paradigm. At test, we presented the scene first, followed after a delay by the test object, which either matched or mismatched …

Exploring the Behavioural Effects of Compound-21 Using Novel Object Recognition and Object in Place Tests in Long Evans Rats
… effects on recognition memory assessed with the Novel Object Recognition (NOR) test. While newer DREADD agonists are available, an understanding of how these novel compounds impact rat behaviour unspecific to DREADD activation is lacking. Therefore, I sought to test whether the DREADD agonist, …

Validation of an animal model of cognitive dysfunction associated with schizophrenia. Development and validation of the novel object recognition task using behavioural manipulations and psychotomimetic dosing regimens to induce cognitive deficits of relevance to schizophrenia in hooded-Lister rats.
… reported in chapter 3 were to establish a set of objects with equal preference in the NOR (novel object recognition) test. Furthermore, the inter-trial-interval (ITI) of the NOR test was investigated in an attempt to elucidate the effects of time and location of the rats during the ITI on the …

Impact of adult hippocampal neurogenesis on behavior
… neurons contribute to behaviors such as CFC and novel object recognition (NOR). NOR was assessed in mice after neurogenesis was arrested using focal x-irradiation of the hippocampus, or a reversible, genetic method in which glial fibrillary acidic protein-positive neural progenitor cells are …

Individual Differences in Zebrafish (<i>Danio rerio</i>) Behavior: Implications for Personality
… mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three …

Temperament and early word learning : the effect of shyness on referent selection and retention
… can impact on the disambiguation and learning of novel word meanings, focusing on the effects of shyness, defined as an aversion to novelty in social situations (Putnam, Gartstein & Rothbart, 2006). A systematic pattern of attention during labeling is crucial in supporting children's novel word …

What not to swear: how do children learn bad words?
… the differences in how children acquire a novel taboo word compared to a novel object word. Three- to 8-year-olds (N=97) saw a short video featuring nonsense words that were framed as either novel object words or novel taboo words. Children identified the nature of the word (i.e., good/bad, …

Young Children's Coordination of Label Extension Across the Senses
… usually avoid extending two labels to the same object, they tend not to do so across the senses (Scofield, Hernandez-Reif, & Keith, 2009). In two experiments, 3- and 4-year-olds learned a label for a visual training object, then examined two hidden objects manually. One was the training object …

Variation drives response to urbanisation: Evolutionary ecology of two introduced birds within anthropogenic environments : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… alteration and fragmentation, which leads to novel challenges for wildlife. Wildlife colonising anthropogenic habitats confront new conditions, such as air and noise pollution, limited space and food resources, higher levels of competition and predator pressures. Such colonists should display …

Social Behavior and Cognitive Bias in the Domestic Dog (Canis familiaris)
… to three other conditions (control, a novel object, and a model dog) to evaluate the validity of using a model dog as a proxy for a live dog when assessing dog-dog sociability. In general, dogs treated the model dog as intermediate between the live dog and a novel object. Dogs’ scores …

The Effects of noise of Zebrafish (Danio rerio) memory
… a plus maze associative learning paradigm and novel object recognition paradigm. The first experiment results showed a significant drop in the total travelling distance in noise-exposed treatments compared to controls without supplementary noise. Moreover, in the noise treatments, there was a …

Biobehavioral responses to immune skew and free fatty acids

In Chapter 3, the second project utilized a novel exogenous stimulus, palmitic acid (PA). We observed a dose-dependent decrease in home cage locomotion was noted two hours after PA …

Temporal Shifts in Weapon Focus: Comparing Retrograde and Anterograde Effects
… while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a bar where a criminal brandished either a drinking glass …

Words and facts: children's fast mapping, retention and extension
… suggests that a pre-school child can link a novel word with its referent and retain this link up to 1 month later (e.g. Markson & Bloom, 1997). In 4 experiments, I investigated the retention of fast mapped novel words and facts after 1 week in 3- and 4-year-old children. In the fifth and …

A comparison point of view video modeling and video self-modeling for preschool-aged children with autism spectrum disorder
… modeling compared to video self-modeling using a novel object retrieval task. A multiple baseline, across participants research design was used to assess four, three to four-year-old children with a primary diagnosis of autism. Although both forms of video modeling were successful in teaching the …

Effects of Prompting and Fading Procedures to Establish Following the Line of Regard in A Child with Autism

Experiment II used a succession of interventions to assess incidental learning of novel object names. Results …

Neonatal Phencyclidine (PCP) induced deficits in rats: A behavioural investigation of relevance to schizophrenia.

Addressing Occlusion in Panoptic Segmentation

In this work, we propose a novel object classification method based on compositional modeling and explore its effect in the context of the newly introduced panoptic segmentation task. The panoptic segmentation task combines both semantic and instance segmentation to perform …

From perceptual to semantic representations in the human brain
Humans are capable of recognizing a myriad of objects in everyday life. To do that, they have evolved the ability to detect their commonalities and differences, moving from perceptual details to construct more abstract representations that we call concepts, which span entire categories (such as the …

Locus-coeruleus norepinephrine system function in a developmental animal model of schizophrenia: the socially isolated rat
