| Abstract: Rich-to-lean transitions have been shown to function aversively for several species, including humans, rats, and pigeons (e.g., Perone & Courtney, 1992). In the current study, pigeons pecked under a multiple fixed-ratio fixed-ratio schedule in which ratios ended in a large/rich or small/lean amount of grain, creating four types of transitions that were each signaled by a different key light color. Pigeons paused approximately twice as long as or longer during rich-to-lean transitions than during other transitions, consistent with previous literature suggesting that pausing functions as a way to escape an aversive situation. As an extension of Langford et al., (2021) that found that chlordiazepoxide differentially decreased rich-to-lean pauses, buspirone, an anxiolytic, was administered acutely (0.3-10.0 mg/kg). At least one dose decreased pauses during rich-to-lean transitions for three out of four pigeons. In contrast, at least one dose of morphine (0.3-1.0 mg/kg) increased rich-to-lean pauses for all pigeons. Finally, results were also compared to those found with chlordiazepoxide for pigeons that were involved in both studies. The current study adds to the rich-to-lean literature and further characterizes the functions of these transitions and their associated stimuli. |

| Abstract: Report of neurofeedback program in one Philadelphia school. Description of biofeedback as a form of Applied Behavior Analysis! Neurofeedback is biofeedback with brainwaves. Image of morphing fractal images reflecting brainwave characteristics. Training protocols are derived using Artificial Intelligence. Ease of use. Behavioral growth areas of 4 students. Self-report of degree of resolution on quantitative descriptors of personally salient issues such as attention, anxiety, obsessionality, behavior, etc. Graphs will summarize subjective data collected through client report throughout participation in biofeedback sessions conducted between February and June 2022. This program was provided free of charge to participants. Data collected for 4 participants will be summarized as: - Percentage score provided based on client report. Client report was recorded after participation in 10 sessions, 20 sessions, and 30 sessions. A total of 4 clients participated in all 30 sessions. - Ratings are based on scale ranging between -100 to +100 relating to frequency, intensity or duration of issues most impacting the quality of life. |

| Abstract: The endogenous opioid hypothesis sheds light on plausible biochemical bases for self-injurious behavior (SIB), lending to its perceived clinical applications. However, few studies exist on the relationship between endogenous opioid antagonists and changes in self-injurious behavior (SIB) Endogenous opioids have chemical structure similar to opium derivatives, indicating they can produce a similar property dependence to that of narcotics. Importantly, consistent release of these peptides can heighten one’s pain threshold overtime, resulting in decreased pain perception. Additionally, for patients who engage in SIB, pain responses may be elicited more frequently, thus triggering an endogenous opioid response. Opioid antagonists such as Naloxone andNaltrexone Hydrochloride, block endogenous opioid transmission, and some prior studies suggest that acute administration of Naloxone may reduce SIB. These findings suggest that opioid antagonists may represent a viable treatment for certain populations that engage in SIB. Thus, the current study was conducted via a retrospective consecutive case series of 17 patients with SIB who were prescribed Naltrexone Hydrochloride during their inpatient admission. Our study aims to highlight consecutive demonstrations of the behavior-altering effects of Naltrexone Hydrochloride on behavior in treatment-resistant populations. |

| Abstract: The common herbicide glyphosate, available for home and garden use, has attracted much recent attention as a carcinogen. However, the behavioral toxicology of glyphosate is currently lacking. The purpose of the present study was to examine the acute and sub chronic effects of glyphosate in adult male and female rats responding under a Fixed Interval 60 second (FI-60”) schedule of water presentation. Acute oral gavage administrations of glyphosate reduced the rate of responding at the lowest concentration tested (0.56 mg/kg). Intermediate to high concentrations (1.0 – 3.0 mg/kg) generally elevated response rates relative to vehicle and non-chemical controls. Sub chronic oral administrations of glyphosate (3.0 mg/ml) administered in the rats post experimental ration of water prior to the deprivation period. Sub chronic administrations marginally suppressed response-rates only after the second day of exposure. On the third day the response rates returned to control values. These current data suggest that minimal exposure to glyphosate may engender previously undetected behavioral disruptions. |
