The basolateral amygdala (BLA) modulates memory consolidation for a variety of types of learning, whereas other brain regions play more selective roles in specific kinds of learning suggesting a role for differential consolidation via distinct BLA pathways. The ventral hippocampus (VH), an efferent target of the BLA, has been suggested to…

Hippocampal ? (3-12 Hz) oscillations are implicated in learning and memory, but their functional role remains unclear. We studied the effect of the phase of local ? oscillation on hippocampal responses to a neutral conditioned stimulus (CS) and subsequent learning of classical trace eyeblink conditioning in adult rabbits. High-amplitude, regular…

Many individuals with autism spectrum disorders (ASD) display stimulus overselectivity, wherein a subset of relevant components in a compound stimulus controls responding, which impairs discrimination learning. The original experimental research on stimulus overselectivity in ASD was conducted several decades ago; however, interventions for…

Three experiments used rats to examine the effect of a single bout of voluntary activity (wheel running) on the acquisition, extinction, and reconsolidation of context conditioned fear. In Experiment 1, rats provided with access to a wheel for 3 h immediately before or after a shocked exposure to a context froze more when tested in that context…

Universities find themselves faced with the conflicting institutional demands of being cathedrals of learning and research as well as introducing managerial and corporate-like structures. Despite many studies in higher education research that focus on how this situation affects the mission of universities, the role of imprinting has not received…

Research on stimulus-stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response-independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response-contingent pairing (RCP) procedure on the vocalizations of three…

Response interruption and redirection (RIRD) is an intervention that involves presenting demands or other types of distracters to interrupt an interfering behavior and redirect it to a more appropriate response. It targets the decrease of repetitive, stereotypic, and self-injurious behaviors. Research indicates that stereotypy is commonly…

Stimuli conditioned with a substance can generate drug-approach behaviors due to their acquired motivational properties. According to implicit theories of addiction, these stimuli can decrease cognitive control automatically. The present study (n = 49) examined whether reward-associated stimuli can interfere with cognitive processes in the absence…

Phosphorylation is a ubiquitous post-translational modification of proteins, and a known physiological regulator of K[superscript +] channel function. Phosphorylation of K[superscript +] channels by kinases has long been presumed to regulate neuronal processing and behavior. Although circumstantial evidence has accumulated from behavioral studies…

Aversive outcomes punish behaviors that cause their occurrence. The prefrontal cortex (PFC) has been implicated in punishment learning and behavior, although the exact roles for different PFC regions in instrumental aversive learning and decision-making remain poorly understood. Here, we assessed the role of the orbitofrontal (OFC), rostral…

Calpain-1 (CANP1) has been shown to play a critical role in synaptic plasticity and learning and memory, as its deletion in mice results in impairment in theta-burst stimulation (TBS)-induced LTP and various forms of learning and memory. Likewise, PHLPP1 (aka SCOP) has also been found to participate in learning and memory, as PHLPP1 overexpression…

This study investigated the effects of tact prompts on the acquisition and retention of divergent intraverbal responding to categorical questions involving conditional discriminations. A 6-year-old boy with autism participated in the study. A multiple probe design across behaviors was used. A tact-prompt procedure was implemented. The results…

B. F. Skinner's (1957) "Verbal Behavior" had a limited influence on empirical research in the first few decades following its publication, but an increase in empirical activity has been evident in recent years. The purpose of this article is to update previous analyses that have quantified the influence of "Verbal Behavior" on…

Background: Two procedures were developed to teach individuals with Autism Spectrum Disorders labels (tacts) for various private events (emotions): Study 1 attempted to distinguish them from pure tacts and mands (requests); and Study 2 attempted to train initiating a conversation with grammatically correct subject-verb-comment construction.…

Numerous investigations have definitively shown amygdalar involvement in delay and contextual fear conditioning. However, much less is known about amygdala contributions to trace fear conditioning, and what little evidence exists is conflicting as noted in previous studies. This discrepancy may result from selective targeting of individual nuclei…
