Background Scatter-hoarding animals store food in multiple locations within their home range and rely on spatial memory for subsequent localization retrieval. The relationship between scatter-hoarding behavior has been widely demonstrated, but the association of gut microbiota with seed-hoarding remains unclear. Methods In this study, by using enclosure tests, tests including an object location...

Unlike most species, after food deprivation, Siberian hamsters increase foraging and food hoarding, two appetitive ingestive behaviors, but not food intake, a consummatory ingestive behavior. We previously demonstrated (Wood AD, Bartness TJ, Am J Physiol Regul Integr Comp Physiol 272: R783-R792, 1997) that increases in food hoarding are triggered by directly decreasing body fat levels through p...

The hypothesis that spatial-memory specialization affects the size of the hippocampus has become widely accepted among scientists. The hypothesis comes from studies on birds primarily in two families, the Paridae (tits, titmice and chickadees) and the Corvidae (crows, nutcrackers, jays, etc.). Many species in these families store food and rely on spatial memory to relocate the cached items. The...

This qualitative study examined multidisciplinary team members' perspectives of their involvement in older adult hoarding cases. Fifteen informants, as representatives of four hoarding teams, described cases in which teams did or did not work well together. Specifically, informants described their (a) team characteristics, (b) awareness of hoarding as a mental health illness, (c) barriers to pr...

Experiential avoidance can be defined as the tendency to avoid contact with unwanted internal experiences. Current conceptualizations of pathological hoarding appear broadly consistent with an experiential avoidant model. Eighty participants in four groups, namely hoarding disorder (HD) without comorbid obsessive-compulsive disorder (OCD), HD with comorbid OCD, non-hoarding OCD, and healthy con...

It is important for animals to adapt to changes in food availability in order to survive. Hoarding is one method ofaccomplishing this and the golden hamster (Mesocricetus auratus) is particularly adept at hoarding. Previous literature suggests a connection between hoarding and stress. To further examine this connection, the present study looked at the effects of illumination and food deprivatio...

This study reports on the development and initial psychometric properties of the Children's Saving Inventory (CSI), a parent-rated measure designed to assess child hoarding behaviors. Subjects included 123 children and adolescents diagnosed with primary Obsessive-Compulsive Disorder (OCD) and their parents. Trained clinicians administered the Children's Yale-Brown Obsessive-Compulsive Scale (CY...
