AI Article Synopsis
- Two experiments were conducted to study how different treatment schedules (massed vs distributed) affect the retention of response-prevention effects in rats learning to avoid shock.
- In the first experiment, 120 rats were trained in a one-way platform and underwent either massed or distributed treatments, while the second experiment involved 160 rats using a one-way shuttle box with similar treatments.
- The results indicated that both treatment types effectively reduced avoidance behavior, and there was no significant difference in retention of avoidance between the massed and distributed treatments, suggesting the findings could have implications for both animal and human behavior studies.
Article Abstract
Two experiments were conducted to estimate the retention of response-prevention effects using massed vs distributed treatments in a model of animal avoidance-learning. In Exp. I, 120 rats were trained to avoid shock in a one-way platform avoidance apparatus. Groups received response-prevention treatment or nontreatment in a 36-min. massed session or in several sessions distributed over a four-day period. In Exp. II, 160 rats were given two trials of escape training in a one-way shuttle box. Groups received response-prevention treatment or nontreatment in a 24-min. session of massed or distributed treatments delivered in one day. Subjects in both studies were tested using a passive-avoidance paradigm immediately following treatment, 24 hours later, and 30 days later. Analysis showed that response-prevention treatments were effective in reducing avoidance behavior and there were no significant differences in retention of avoidance associated with massed vs distributed response-prevention treatments. Implications for animals and humans are discussed, and researchers are encouraged to change from a criterion training procedure to an escape procedure since the latter is a closer analogue to the human condition.

Fear extinction is the foundation of exposure therapy for anxiety and phobias. However, the stability of extinction memory diminishes over time, coinciding with fear recovery. To augment long-term extinction retention, the temporal distribution of extinction learning sessions is critical.

In an auditory statistical learning paradigm, listeners learn to partition a continuous stream of syllables by discovering the repeating syllable patterns that constitute the speech stream. Here, we ask whether auditory statistical learning benefits from spaced exposure compared with massed exposure. In a longitudinal online study on Prolific, we exposed 100 participants to the regularities in a spaced way (i.

This study investigated the effects of spaced and massed repetition on the acquisition and retention of English /b/ and /p/ sounds among Saudi English as a foreign language (EFL) learners. Forty-nine university students participated in a quasi-experimental design comparing two learning conditions: massed repetition and spaced repetition. Participants were taught the pronunciation of 40 new English words containing the target sounds through video-based instruction.

Thermosensitive liposomes (TSLs) have great potential for the selective delivery of cytostatic drugs to the tumor site with greatly reduced side effects. Here we report the discovery and characterization of new thermosensitive small multilamellar lipid nanoparticles (tSMLPs) with unusually high temperature selectivity. Furthermore, the temperature-dependent release of the fluorescent marker calcein from tSMLPs is enhanced by human serum albumin.
