For experiments investigated the effect of adding noncontingent (free) food to an operant contingency during random ratio (RR) and random interval (RI) training and during extinction in rats. Free food was presented during extinction of RI responding in Experiments 1 and 2. Noncontigent food retarded response loss compared to a signaled free food group (Experiments 1 and 2) which declined less rapidly than a control group of no free food (Experiment 1). Free food was presented while the instrumental reinforcement RR and RI probabilities remained unchanged in Experiments and 3 and 4. In contras

Abstract:

This thesis is compromised of three studies in which basic principles of operant conditioning were applied to horses. Autoshaping was examined as a method for horse training. Observational learning was investigated to confirm that naive horses can, in fact, acquire novel behavior by observing experienced horses, and the rate of acquisition with observation is more rapid than spontaneous responding without observation. A third study examined the effect of discriminative stimulus intensity on the acquisition rate of novel behavior. All subjects learned to use an operant conditioning device. Subj

Abstract:

Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed

Abstract:

Human operant studies frequently use points exchangeable for money as reinforcers. Some studies employ more immediately consumable reinforcers to emulate properties of food reinforcers. This study examined demand for points/money and for sound-clips to compare their economic characteristics. Across four participants, demand was often higher and less elastic for points/money than for sounds. During subsequent exposures at each response requirement, demand for sounds often decreased to a greater degree than demand for points/money. Thus, sound-clips seem less durable than points/money across pri

Research on operant learning principles suggests that discriminative stimuli, and negative and positive reinforcement play a role in the maintenance of smoking behavior. Smoking research from a respondent learning paradigm focuses on the role of environmental stimuli that function as elicitors of physiological responses related to smoking. Basic research suggests that compensatory responses may play a role in drug tolerance and relapse. In one preliminary study assessing the role of compensatory responses to smoking stimuli (Machado, 2011), drops in carbon monoxide (CO) were observed only when

Behaving in novel ways is essential to the development of the types of complex performances described by the term creativity, problem solving, and perseverance.

Topographical variability has rarely been examined, nor has operant variability with organisms with baselines featuring stereotypic responding.

But the most difficult thing is to find out if these species have an aim for the future which involves what some call mental time travel. This study is a part of the discussion if the tests in long term planning and foresight can be explained by associative learning and the ability of self control in highly trained animals.

Abstract:

According to the DSM-IV- TR (American Psychiatric Association, 2000), one of the core deficits in autism is in the impairment of social interaction. Some have suggested that underlying these deficits is the reality that individuals with autism do not find social stimuli to be as reinforcing as other types of stimuli (Dawson, 2008). An interesting and growing body of literature supports the notion that symptoms in autism may be caused by a general reduction in social motivation (Chevallier et al., 2012).

The mechanisms which account for the diminished responsiveness (tolerance) of an individual to a drug, as a result of prior exposure to that drug, are not yet fully understood.

The first study examined the initial dose-related effects of ethanol (1, 2, or 3 g/kg i.p.); the second study examined the effect of ethanol (2.5 g/kg i.p.

Motor cortex, basal ganglia (BG), and thalamus are anatomically arranged in a recurrent loop whose activity is hypothesized to be involved in the selection of motor actions. Direct (dSPN) and indirect (iSPN) striatal projection neurons receive excitatory input from cortex, and are thought to oppositely modulate cortical activity via BG output to thalamus. Here, we test the central tenets of this model in head-restrained mice performing an operant conditioning task using optogenetic manipulation of dSPNs and iSPNs to determine the effects of activity in each pathway on primary motor cortex.

Abstract:

Resurgence is the relapse of an extinguished instrumental behavior that can occur when an alternative behavior that was introduced to replace it is itself extinguished. In a typical resurgence experiment, rats are trained to make a response (R1) for food reinforcers. In a second phase, responses on R1 are no longer reinforced, but a new response (R2) is introduced and responses on it are reinforced. During a third phase, reinforcement for R2 is removed and behavior on R1 often returns (or "resurges") despite remaining on extinction. The current experiments were designed to examine the effects

Abstract:

The present study contributes an apparatus and research paradigm useful in generating human performances sensitive to concurrent schedules of reinforcement. Five participants produced performances observed to be under temporal and ratio control of concurrent fixed interval-fixed ratio schedules. Two aspects of interaction between FI and FR schedules were distinguishable in the data. First, interaction between two schedules was observed in that changes in the value of one schedule affected behavior reinforced on another schedule. Second, switching from one pattern to the other functioned as an

Abstract:

Spinal cord injury (SCI) manifests signs of spasticity, plantar flexor (PF) hyperreflexia and ankle clonus, and deficits in motor function. In individuals with motor-incomplete SCI (MISCI), ankle clonus may limit independent walking function. Ankle clonus is attributed to enhanced soleus stretch reflex (SSR) excitability due to decreased supraspinal input and maladaptive reorganization of spinal reflex circuitry. We explored these questions: 1. What are the biomechanical, clinical, and neurophysiologic correlates of ankle clonus? 2. Does locomotor training improve ankle clonus and walking

Abstract:

La dopamine (DA) contrôle l'apprentissage lié à la récompense en régulant l'activité et la plasticité de la transmission corticostrialale. Les effets à long terme de la DA impliquent des changements dans la transcription des gènes. Le but de ce travail de thèse est d'étudier les changements transcriptionnels produit dans le striatum ventral, dorsal et cortex préfrontal, par un protocole d'apprentissage opérant ou après une activation du système de la récompense par des injections de cocaïne. Les neurones épineux moyens du striatum peuvent être séparé en deux populations fonctionnelles sur la b

Abstract:

This study investigated nicotine place conditioning in early postweanling and adolescent male and female rats neonatally treated with quinpirole, a dopamine D(2)/D(3) agonist. Previous research has shown that neonatal quinpirole treatment results in an increase of dopamine D(2)-like receptor sensitivity that persists throughout the animal's lifetime, relevant to psychosis. Rats were neonatally treated with quinpirole or saline from postnatal day (P)1-21, and animals were conditioned with nicotine or saline daily from P23-30 as early postweanlings or P32-39 as adolescents in a two- or three-cha

Full text

Abstract:

The effects of two consequence delivery methods on task acquisition were evaluated within a multi-element design. A typical 3 year-old child and a 4 year-old child with autism participated in this study. The task for both children was to select a picture after the experimenter said its name. The consequence in one condition consisted of the experimenter handing the edible item to the children. The consequence in the other condition consisted of the children retrieving the edible item directly from the apparatus, located in a crevice underneath each picture. Results show slightly quicker acquis

Abstract:

Self injurious behavior (SIB), such as self-biting and head-banging, has been reported to occur in approximately 10% of captive, individually housed primates (Novak, Kinsely, Jorgensen, and Hazen, 1998). Accounts of the causes of SIB range from environmental to physiological. However, to date, no researchers have investigated the possible influence of social consequences, delivered by handlers and keepers, in the maintenance of SIB. There is only one research report showing that self-injury can be shaped in primates by the manipulation of food as a reinforcing consequence for the animal's beha
