Tallot, Lucille; Diaz-Mataix, Lorenzo; Perry, Rosemarie E.; Wood, Kira; LeDoux, Joseph E.; Mouly, Anne-Marie; Sullivan, Regina M.; Doyère, Valérie – Learning & Memory, 2017
The updating of a memory is triggered whenever it is reactivated and a mismatch from what is expected (i.e., prediction error) is detected, a process that can be unraveled through the memory's sensitivity to protein synthesis inhibitors (i.e., reconsolidation). As noted in previous studies, in Pavlovian threat/aversive conditioning in adult rats,…

Eckmier, Adam; de Marcillac, Willy Daney; Maître, Agnès; Jay, Thérèse M.; Sanders, Matthew J.; Godsil, Bill P. – Learning & Memory, 2016
Rodents are exquisitely sensitive to light and optogenetic behavioral experiments routinely introduce light-delivery materials into experimental situations, which raises the possibility that light could leak and influence behavioral performance. We examined whether rats respond to a faint diffusion of light, termed caplight, which emanated through…

Williams, Amy R.; Kim, Earnest S.; Lattal, K. Matthew – Learning & Memory, 2019
A fundamental property of extinction is that the behavior that is suppressed during extinction can be unmasked through a number of postextinction procedures. Of the commonly studied unmasking procedures (spontaneous recovery, reinstatement, contextual renewal, and rapid reacquisition), rapid reacquisition is the only approach that allows a direct…

Romesburg, H. Charles – American Biology Teacher, 2019
A classroom exercise is described in which college students take part in creating and supporting an evolutionary hypothesis that explains effort grunting. The exercise holds their interest throughout and readies them to understand hypotheses of animal and plant evolution. It informs them about the dependence of cultural evolution upon biological…

Brown, Esther L.; Shin, Naomi – First Language, 2022
Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Bisby, Madelyne A.; Baker, Kathryn D.; Richardson, Rick – Learning & Memory, 2018
NMDA receptors (NMDARs) are considered critical for the consolidation of extinction but recent work challenges this assumption. Namely, NMDARs are not required for extinction retention in infant rats as well as when extinction training occurs for a second time (i.e., reextinction) in adult rats. In this study, a possible third instance of…

Lee, Jessica C.; Hayes, Brett K.; Lovibond, Peter F. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2018
Two experiments tested whether a peak-shifted generalization gradient could be explained by the averaging of distinct gradients displayed in subgroups reporting different generalization rules. Across experiments using a causal judgment task (Experiment 1) and a fear conditioning paradigm (Experiment 2), we found a close concordance between…

Needham, Mick – ProQuest LLC, 2018
Despite an abundance of research on interventions to improve social skills of young children with intellectual disabilities (ID), there is limited research on interventions aimed at improving social skills of adults with ID. The purpose of this single-subject study was to evaluate the outcomes of the Behavioral Opportunities for Social Skills…

Goehring, Jenny L.; Hughes, Michelle L. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: This study evaluated the use of telepractice for measuring cochlear implant (CI) behavioral threshold (T) levels in children using conditioned play audiometry (CPA). The goals were to determine whether (a) T levels measured via telepractice were not significantly different from those obtained in person, (b) response probability differed…

Cassini, Lindsey F.; Flavell, Charlotte R.; Amaral, Olavo B.; Lee, Jonathan L. C. – Learning & Memory, 2017
Retrieval of an associative memory can lead to different phenomena. Brief reexposure sessions tend to trigger reconsolidation, whereas more extended ones trigger extinction. In appetitive and fear cued Pavlovian memories, an intermediate "null point" period has been observed where neither process seems to be engaged. Here we investigated…

Peterson, Stephanie M.; Frieder, Jessica E.; Quigley, Shawn P.; Kestner, Kathryn M.; Goyal, Manish; Smith, Shilo L.; Dayton, Elizabeth; Brower-Breitwieser, Carrie – Education and Treatment of Children, 2017
One measure of success for interventions treating problem behavior is the effects achieved in the face of a challenge (e.g., changes in reinforcement schedules, lapses in treatment integrity); one hopes to demonstrate persistence of appropriate alternatives and the absence of resurgence of target behaviors. The present study successfully treated…

Leung, Hiu T.; Holmes, Nathan M.; Westbrook, R. Frederick – Learning & Memory, 2016
Four experiments used between- and within-subject designs to examine appetitive-aversive interactions in rats. Experiments 1 and 2 examined the effect of an excitatory appetitive conditioned stimulus (CS) on acquisition and extinction of conditioned fear. In Experiment 1, a CS shocked in a compound with an appetitive excitor (i.e., a stimulus…

Henley, Amy J.; Hirst, Jason M.; DiGennaro Reed, Florence D.; Becirevic, Amel; Reed, Derek D. – Analysis of Verbal Behavior, 2017
This study evaluated the effects of four instructional variants on instruction following under changing reinforcement schedules using an operant task based on Hackenberg and Joker's "Journal of the Experimental Analysis of Behavior," 62, 367-383 (1994) experimental preparation. Sixteen college-aged adults served as participants and were…

Lyons, Lisa C.; Gardner, Jacob S.; Gandour, Catherine E.; Krishnan, Harini C. – Learning & Memory, 2017
We investigated the in vivo role of protein degradation during intermediate (ITM) and long-term memory (LTM) in "Aplysia" using an operant learning paradigm. The proteasome inhibitor MG-132 inhibited the induction and molecular consolidation of LTM with no effect on ITM. Remarkably, maintenance of steady-state protein levels through…

Kalbe, Felix; Schwabe, Lars – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2020
Stimuli encoded shortly before an aversive event are typically well remembered. Traditionally, this emotional memory enhancement has been attributed to beneficial effects of physiological arousal on memory formation. Here, we proposed an additional mechanism and tested whether memory formation is driven by the unpredictable nature of aversive…
