FOK产生机制的再验证

通过用有意义联系和无意义联系的两种中文词对作为识记材料,在以前实验研究基础上,进一步验证关于FOK(Feelingof Knowing)产生机制的两种理论假说,即靶项日记忆强度假说(或靶项目提取可能性假说)与线索熟悉性假说。实验结果表明,靶项目记忆强度和线索熟悉性程度都能决定FOK判断等级的高低,说明两种假说并非绝对对立,非此既彼。但此二因素都需达到一定程度,才能显著影响FOK判断等级的高低。     

A pinch or a lesion: a reconceptualization of biting consequences in mice

Intruder and resident male colony mice exhibit an array of distinct defensive and offensive behaviors. Intruders typically show more boxing, flight, defensive sideways position, on the back position and general locomotion, while residents exhibit higher levels of attack, olfactory investigation, aggressive grooming, and biting, with a preference for dorsal bite locations. Here, analysis of bite locations on the body of the intruder mice showed that the majority of bites produced few lesions (i.e. actual puncturing of the skin) when compared to scrapes or no markings. Most bites were directed to the back of the opponent animal with very few bites directed towards the opponents' vulnerable ventrum. In particular, bites directed at the relatively hairless ventrum produced no lesions. These findings, along with previous work on mice and rats, suggest that intraspecific offense with preferred target sites for biting, facilitates an effective but largely nonwounding interaction between resident and intruder mice. Furthermore, bruise and wound analyses suggest an association between bite targets and tissue damage. The preference for specific bite locations may be complimented by a differential intensity of attack, with the back attracting the strongest bites and the ventrum the weakest. This apparent nonwounding fighting pattern contradicts the current evaluation of rodent wounding severity in this paradigm and can therefore refine the usage of this model and of the protocols associated with it.

The effects of phencyclidine and chlordiazepoxide on target biting of confined male mice

Target-biting of confined mice increases following delivery of tail shock and decreases during a tone that precedes the shock. Both phencyclidine and chlordiazepoxide reduced biting (dose dependently) following shock and had no effect on biting during the tone. These observations are discussed in reference to previous reports, which infer that the effects of phencyclidine and chlordiazepoxide on aggression might depend upon the baseline rate of the behavior.     

Aggressive reactions of ducklings to a nonliving target object

This study asked whether ducklings' forceful pecks at a nonliving target object could be validly identified as aggressive. Previously isolated ducklings were exposed to a small cylindrical object that could serve as a target for aggressive pecks and as an object for attachment. After initially attempting to flee from the target, they vigorously pecked at it and also showed signs of the formation of a social (imprinting) attachment. In all important respects this pattern of behavior was identical to the pattern of escape, aggressive pecks, and attachment seen when a previously isolated duckling first encounters a conspecific. Social housing, a manipulation which attenuates aggression against live targets in ducklings and other species, reduced pecking at the nonliving target object. Early aversive stimulation, which enhances aggression against live targets, increased pecking at the object. These findings support the use of nonliving targets in the study of aggression in ducklings.     

The control response in assessing resurgence: Useful or compromised tool?

Resurgence experiments sometimes include an operandum on which a history of reinforcement has not been experimentally established. The purpose of this control operandum is to rule out a generalized increase in responding when the alternative response is extinguished as being the cause of the resurgent target response. A review of the results of experiments conducted with both nonhumans and humans in which a control operandum was included shows that control- operandum responding is more common in the latter and almost nonexistent in the former. Both the presence and absence of responding on the control operandum, however, are subject to multiple interpretations thereby rendering it a compromised tool. Alternatives to using a control operandum to rule out extinction induction as the basis for resurgence include a preresurgence test control procedure and a differential resurgence procedure.     

Comparison of upright and flipped spoon presentations to guide treatment of food refusal

The current study examined the effects of bite placement with a flipped versus upright spoon on expulsion and mouth clean (product measure of swallowing) in the treatment of 3 children diagnosed with a pediatric feeding disorder and oral-motor deficits. For all 3 participants, extinction in the form of nonremoval of the spoon led to improvements in inappropriate mealtime behavior and acceptance of bites; however, re-presentation did not reduce expulsion or improve mouth clean. Results showed a lower level of expulsion and higher percentage of mouth clean during flipped spoon presentations and re-presentations for all participants. Findings from follow-up analyses supported transitioning back to an upright spoon in all 3 cases, although the time required for this to occur differed across participants.     

Building Blocks for Older Adult Ministry

SUMMARY

The final building block is deciding what program fits ministry goals, congregational resources and skills, and the needs of the older adults who will benefit from this ministry. A final form is used to choose, from the many options gathered in the previous steps, which ministries to begin, at this time, for this group of people, with these specific resources, be they congregational resources or those from community collaboration. Choosing target dates for specific tasks and assigning those tasks to specific committee member is crucial for success. The place of attendance in declaring success or failure is discussed. Using the OAM mission statement as a basis for continuing evaluation is suggested.     

Testing Target Congruence Theory on Emotional Abuse Victimization Experienced by Heterosexual and LGBQ College Students

Criminological theories traditionally used to explain crime and deviance have now been applied to explain physical intimate partner violence (IPV) experienced by heterosexual and LGBQ victims. Notably missing, however, are studies that test theories that explain why individuals may become victims of emotional abuse by sexual orientation. To this end, we applied target congruence theory to examine the influence of target vulnerability, gratifiability, and antagonism on emotional abuse experienced by college students. Data obtained from two public universities (Heterosexuals=366, LGBQ=113) showed partial support for the theory, with target vulnerability consistently predicting emotional abuse victimization regardless of sexual orientation.     

Good and Bad Years: An Index of American Social,Economic, and Political Threat (1920–1986)

Information provided by 196 U.S. history professors, indicating the degree to which they considered each of the years from 1920 to 1986 threatening to the established order and way of life in America, was pooled to form a social, economic, and political threat (SEPT) index. Interrater reliability was high, and substantial test-retest reliability was evident for a selected subsample over a 6-month period. The index significantly correlated with 11 objective indices of threat, including the suicide rate, unemployment rate, rise and fall of common stocks, and number of military men on active duty. Several studies involving threat and authoritarianism were replicated and in some instances extended with the SEPT index (McCann & Stewin, 1984; Sales, 1972, 1973). The pseudo-archival SEPT index has utility when relatively global estimates of prevailing threat are required for historiometric research testing a diversity of hypotheses gleaned from psychological, sociological, historical, and political science theories.
