The Effect of Self-Investment on Hoarding Tendency of Chinese College Students:Role of Psychological Connections

Because of factors such as energy and time one invests in an object,the stronger the connection,value,and reluc-tance to lose said object individual will have.Hoarding behavior arises when individuals incorporate a strong attachment with themselves to an object.The purpose of this study is to examine the effect of self-investment on hoarding tendency and the roles of possession-self link and liking level in this connection.A hypothetical model of the relationship between self-investment,possession-self link,liking level,and hoarding tendency was tested.A convenience sampling method was used to survey 450 college students in Yunnan Province on either a paper-based or online self-report scale.The data were collected using self-investment,possession-self link,and liking level questionnaires,as well as the Saving Inventory Revised.Results showed positive relationship between the study variables,ranging from 0.37 to 0.87.College students’self-investment had a direct positive pre-dictive effect on hoarding tendency;self-investment,in turn,indirectly predicted hoarding tendency through the mediating effect of possession-self link;and individual liking level of items had a moderating effect for self-invest-ment on the possession-self link.This study shows how self-investment affects the hoarding tendency of college students,and the results of this study also help demonstrate the value of self-investment and possession-self link in optimizing students’hoarding tendency and thus promoting good psychological status.

An Overview of the Connection between Hoarding Disorder and Substance Use Disorder

This essay explores the connections between Hoarding Disorder and Substance Use Disorder,two distinct mental health conditions with clear diagnostic criteria in the DSM-5.Hoarding Disorder,marked by excessive possession accumulation and difficulties in letting go,affects 2-6%of the global population,leading to severe consequences.Potential causes include genetic predisposition,neural issues,and traumatic experience.Substance Use Disorder is influenced by more societal factors.Both disorders share a comorbidity in Attention-Deficit/Hyperactivity Disorder(ADHD).Network analysis shows a strong direct relationship between Hoarding Disorder and ADHD,while social influences increase ADHD prevalence in Substance Use Disorder individuals.Moreover,both disorders benefit from Cognitive Behavioral Therapy(CBT).Exposure and Ritual Prevention effectively address hoarding symptoms,while CBT for Substance Use Disorder focuses on the interplay between thoughts,emotions,and actions.Despite being classified as a mental illness in DSM-5,Hoarding Disorder receives less attention than Substance Use Disorder.This essay aims to raise awareness of Hoarding Disorder by highlighting its commonalities with Substance Use Disorder in terms of causes,comorbidities,and treatment approaches.

Panic buying? Food hoarding during the pandemic period with city lockdown

Food hoarding is prevalent during the COVID-19 pandemic.To investigate the mechanism of urban consumers’food hoarding behaviors,we categorize hoarding motives into rational and irrational ones.Using random online survey samples from three cities in China,we employ the multivariate probit model to investigate the rational and irrational motives on food hoarding behavior.Our results confirmed the existence of both rational and irrational food hoarding,and also found factors attributing to the different buying behaviors.The amount of food at hand and the expectation on the infection possibility of COVID-19 are two major factors affecting rational hoarding.Bad mood and herd psychology are factors contributing to panic buying.This study provides an empirical evidence to support intervention policies aiming at mitigating panic buying behavior.

HOARDING BEHAVIOR OF EURASIAN NUTCRACKER ANDITS ROLE IN THE DISPERSAL OF KOREAN PINE

The studiy was carried out in Autunm from 1993 to 1995 in Liangshui Natural Reserve in NE China. After eating some seeds, Nuterackers fly over 1 km or more to some area with seeds in its sublingual pouch and cache the seeds in the ground for future use. Each cache contains 1-7 seeds commonly. Caching habitats are in accord with seedlings sites. The quantities of caching seeds are very large. Caching depth is adaptable for seed germination. The Eurasian Nutcrackers have an important effect on seeds dispersal of Korean pine.

Hoarding behaviour in a person with dementia

Hoarding is defined as the acquisition and failure to discard a large number of possessions,resulting in significant cluttering and distress to themselves and others.When the severity of hoarding behaviour increases with age,the risk of vulnerability increases,especially in older people with dementia.This pathological comportment tends not to be identified until the patient is hospitalized and needs a home visit for safe discharge planning or when major concerns arise from family or the public.Diagnosing hoarding disorders from secondary conditions with hoarding behaviour can be challenging.A number of assessments and intervention strategies for hoarding can be implemented to improve the health and safety of these patients.A case of a patient with hoarding behaviour in a patient with dementia is described.

Disentangling the relative contributions of variables determining the divergence of hoarding strategies of rodents

Understanding the driving mechanism of the divergence of hoarding strategies of animals(i.e.,scatter-hoarding vs.larder-hoarding)is crucial to understand the ecological and evolutionary implications of plant-animal interactions.Zhang et al.(2022)compiled a global-scale dataset from the published literature including 183 species of seed-hoarding rodents,and concluded that phylogenetic conservatism,functional traits,and environmental factors counted for the hoarding behavior divergence of rodents.A more thought-provoking question may be asked:Do these variables contribute equally or not to explain the divergence of hoarding strategies?Here,we re-analyzed Zhang et al's(2022)dataset using partial Ralk calculation(Ives 2019)to parse out the relative contri-lik butions of these variables.

Asymmetric competition for seeds between two sympatric food hoarding rodents:implications for coexistence

Asymmetric competition occurs when some species have distinct advantages over their competitors and is common in animals with overlapping habitats and diet.However,the mechanism allowing coexistence between asymmetric competitors is not fully clear.Chinese white-bellied rats(Niviventer confucianus,CWR)and Korean field mice(Apodemus peninsulae,KFM)are common asymmetric competitors in shrublands and forests west of Beijing city.They share similar diet(e.g.plant seeds)and activity(nocturnal),but differ in body size(CWR are bigger than KFM),food hoarding habit(CWR:mainly larder hoarding;KFM:both larder and scatter hoarding),and ability to protect cached food(CWR are more aggressive than KFM).Here,we tested seed competition in 15 CWR-KFM pairs over a 10-day period under semi-natural enclosure conditions to uncover the differences in food hoarding,cache pilferage,and food protection between the 2 rodents,and discuss the implication for coexistence.Prior to pilferage,CWR harvested and ate more seeds than KFM.CWR tended to larder hoard seeds,whereas KFM preferred to scatter hoard seeds.Following pilferage,CWR increased consumption,decreased intensity of hoarding,and pilfered more caches from KFM than they lost,while KFM increased consumption more than they hoarded,and they preferred to hoard seeds in low and medium competition areas.Accordingly,both of the 2 rodent species increased their total energy consumption and hoarding following pilferage.Both rodent species tended to harvest seeds from the source,rather than pilfer caches from each other to compensate for cache loss via pilferage.Compared to CWR,KFM consumed fewer seeds when considering seed number,but hoarded more seeds when considering the seeds’relative energy(energy of hoarded seeds/rodent body mass2/3)at the end of the trials.These results suggest that asymmetric competition for food exists between CWR and KFM,but differentiation in hoarding behavior could help the subordinate species(i.e.KFM)hoard more energy than the dominant species(i.e.CWR),and may contribute to their coexistence in the field.

Differentiation in seed hoarding among three sympatric rodent species in a warm temperate forest

Although seed hoarding by rodents has been extensively studied,differentiation in seed-hoarding behaviors among sympatric rodent species has not been well investigated.Using semi-natural enclosures,we demonstrated that three sympatric rodent species showed clear differentiation in food selection,scatter versus larder hoarding behaviors and eating behaviors when offered seeds of four plant species from a warm temperate forest in northern China.The large field mouse Apodemus peninsulae preferred seeds of wild apricot(Prunus armeniaca)and Liaodong oak(Quercus liaotungensis),whereas the Chinese white-bellied rat Niviventor confucianus preferred seeds of cultivated walnut and Liaodong oak,and the David’s rock squirrel Sciurotamias davidianus preferred seeds of cultivated walnut,wild apricot and Liaodong oak.All three rodents showed larder hoarding of seeds from all four plant species,but the large field mouse showed scatter hoarding of wild apricot,and the David’s rock squirrel showed scatter hoarding of Liaodong oak and wild walnut.Acorns of Liaodong oak,which have a soft seed hull,were more often eaten in situ,whereas wild walnuts,which have a hard seed hull and more tannin,were less hoarded by all rodent species.Differentiation in the scatter versus larder hoarding behaviors of sympatric rodent species suggests that sympatric rodents play different roles in the regeneration of different sympatric plant species.

关于四川彭州竹瓦街出土“列罍”问题的再研究

20世纪50年代后,四川彭县竹瓦街的两处窖藏出土过两批青铜罍。第一批在1959年,一号窖藏出土五件青铜罍;第二批在1980年,二号窖藏出土四件青铜罍。冯汉骥认为一号窖藏出土的五件青铜罍可视之为列罍,而后赵殿增赞同冯汉骥的观点,并认为二号窖藏原来应为五件,由于某种原因有一件未埋入坑中。本文认为竹瓦街的青铜罍不符合所谓“列罍”标准。从理论上来说,窖藏铜器的性质不同于墓葬铜器,组合关系不可信,利用窖藏资料来研究青铜器的组合关系,是有风险的。从实际情况来看,竹瓦街一号窖藏出土五件罍,二号窖藏出土四件罍,已经显示出两处出土罍的数量不同,而且其中有成双成对的三组罍,也明显不符合“列器”的规则。况且,迄今为止,还没有发现竹瓦街以外的中国其他地区有出土所谓“列罍”的考古实例。

张广才岭森林啮齿动物对种子扩散距离的生境差异

为探究生境与啮齿动物对种子扩散之间的关系,于2020年9—11月,选取黑龙江省张广才岭4种生境(阔叶林、林缘、针阔混交林、人工落叶松林)为试验地点,采用塑料标签标记法,以红松(Pinus koraiensis)、毛榛(Corylus mandshurica)、蒙古栎(Quercus mongolica)种子为材料进行种子扩散试验。结果表明,①植物种子在人工落叶松林(2.92±2.24 m)中的扩散距离极显著小于阔叶林(3.69±1.92 m)、林缘(3.46±2.29 m)、针阔混交林(3.43±2.25 m)(P<0.01),该生境为啮齿动物提供了更好的隐蔽环境,人为干扰程度在4种生境中最小。其余3种林型间种子扩散距离差异不显著。②不区分生境时,3种种子的扩散距离分别为红松(4.38±3.62)m、毛榛(3.29±2.70)m、蒙古栎(2.16±2.66)m。③蒙古栎、红松、毛榛种子的扩散距离集中分布1~6 m的范围。啮齿动物对种子的扩散距离与生境的隐蔽性和人为干扰程度有关,生境中的隐蔽状态越好,扩散距离越小;人为干扰越大,扩散距离越大。啮齿动物对植物种子的扩散选择具有差别。不区分生境时,红松和毛榛种子扩散距离差异不显著,但两者扩散距离都显著大于蒙古栎种子。

Effects of thinning on scatter-hoarding by rodents in temperate forest

Deforestation and thinning are human activities that can destabilize the forest ecological system and,conse­quently,impact significantly on habitat and behavior of forest-dwelling animals.This hypothesis was tested in Yugong in the Mount Taihangshan area by comparing the tracks of tagged seeds of Armeniaca sibirica.in sites of unthinned and thinned forests.Our results showed that:(i)the diversity of vegetation and rodents drastical­ly reduced in sites with thinned forests,compared to unthinned sites;(ii)the amount of both removed and scat­ter-hoarded seeds significantly declined in sites with thinned forests,compared with the unthinned sites;(iii)there was no significant difference observed in the distance of seed dispersal between the thinned and unthinned areas;and(iv)the thinning did not show a significant change to the model of cache size.These results suggest­ed that the thinning of forests negatively influenced the species richness and food-hoarding behavior of rodents.In addition,the results indicated that the weakened scattered-hoarding might be disadvantageous to seedling re­cruitment and forest restoration.

The effects of seed detectability and seed traits on hoarding preference of two rodent species

Seed traits play an important role in affecting seed preference and hoarding behaviors of small rodents.Despite greatly affected by seed traits,seed detectability of competitors represents pilfering risks and may also modify seed hoarding preference of animals.However,whether seed traits and seed detectability show consistent effects on seed hoarding preference of animals remain largely unknown.Here,we explored how seed traits and seed detectability correlate with seed hoarding preference of Leopoldamys edwardsi and Apodemus chevrieri in a subtropical forest.Despite the effects of seed coat thickness and caloric value on hoarding preference of L.edwardsi,we detected no significant effects of other seed traits on hording preference of the 2 rodent species.There was no correlation between larder-hoarding preference and inter-or intra-specific seed detectability of L.edwardsi;however,seed detectability of L.edwardsi was negatively correlated with its own scatter-hoarding preference.Although scatter-hoarding preference of A.chevrieri was not correlated with inter-and intra-specific seed detectability,larder-hoarding preference of A.chevrieri was positively correlated with intra-specific seed detectability.Our study may provide evidence that intra-specific seed detectability rather than seed traits and inter-specific pilfering risks play an important role in modifying seed hoarding preference of rodents.
