The effects of context reinstatement as means of enhancing 5‐ and 6‐year‐old children's event memory in repeated interviews after a 6‐month delay were examined. Children were interviewed immediately after the event (baseline interview) and twice at a 6‐month delay, with 24 hours between interviews. The first 6‐month interview was conducted in a perfect‐context reinstatement (n = 15), imperfect‐context reinstatement (n = 16), or no‐context reinstatement (n = 15) condition. The second 6‐month interview was conducted 24 hours later with no‐context reinstatement for all children. Context reinstatement attenuated the effects of delay on recall. The accuracy of the details reported was greater in the perfect‐context compared to the imperfect‐context and no‐context conditions. Details repeated between the immediate‐baseline interview and in the first 6‐month interview were more accurate than details repeated between the first and second 6‐month interview. There was no increase in recall (hypermnesia) across the first and second 6‐month interviews in any condition. Practical implications of these findings are discussed.

People often describe uncertain quantities by suggesting a lower or upper limit of an uncertainty interval, rather than the complete range. Five studies are reported, which demonstrate how interval limits function as provisional reference points (PRP), conferring evaluative meanings to the target objects, by suggesting downward or upward comparisons. Thus, a price above X appears expensive, whereas a price below Y appears cheap, even when Y > X. This can give rise to framing effects: a purchase can appear to be recommended or advised against, and a seller can appear as optimistic or pessimistic, and, more generally, an estimate can indicate abundance or scarcity, depending upon which boundary (upper or lower) that is selected. Furthermore, inclusive lower bounds (minimum, at least) and upper bounds (maximum, at most) differ from exclusive lower (more than, above) and upper bounds (less than, below), by suggesting possible (likely) rather than implausible (unlikely) values.

A random sample of 505 American Counseling Association (ACA) members completed a questionnaire that evaluated respondents' ratings of the importance of 9 competencies developed at the Summit on Spirituality (G. Miller, 1999; “Summit Results,” 1995) meetings to effectively address spiritual and religious issues in counseling practice. Results suggest that, in general, ACA members strongly support the importance of the competencies for effective counseling practice.  相似文献

Guidance to identify and manage clients with a perceived high risk for future violence is of great importance for mental health professionals. In the past decade, several structured instruments have been developed to assess risk of future violence. Awareness of the limits and abilities of such instruments is required. This article reviews the most well‐known risk assessment tools and provides recommendations for how to approach the area of violence risk assessment.  相似文献

In research on selective exposure to information, people have been found to predominantly seek information supporting rather than conflicting with their opinion. In most of these studies, participants were allowed to search for as many pieces of information as they liked. However, in many situations, the amount of information that people can search for is restricted. We report four experiments addressing this issue. Experiment 1 suggests that objective limits regarding the maximum number of pieces of information the participants could search for increases the preference for selecting supporting over conflicting information. In Experiment 2, just giving participants a cue about information scarcity induces the same effect, even in the absence of any objective restrictions. Finally, Experiment 3 and 4 clarify the underlying psychological process by showing that information limits increase selective exposure to information because information search is guided by the expected information quality, which is basically biased towards supporting information, and information limits act to reinforce this tendency.

Differences in the distribution of arginine vasopressin (AVP) and a subtype of AVP receptors, the V1a receptor, may explain dissimilarities in social behavior of monogamous and non‐monogamous rodents. Intracerebroventricular infusions of AVP and a V1a antagonist were used in sexually naive males of two mouse species, the monogamous and highly aggressive California mouse (Peromyscus californicus) and the non‐monogamous and less aggressive white‐footed mouse (P. leucopus), to begin testing the interaction between the social system of a species and the effects of AVP on aggression. Two testing conditions, the resident‐intruder aggression test (R‐I) and the neutral arena aggression test, were used because they may differ in function and underlying biological mechanisms. In the R‐I test, administration of the antagonist lengthened attack latencies in California mice. In contrast, blocking V1a receptors did not alter attack latencies in the R‐I test in white‐footed mice or in the neutral arena aggression test in both species. AVP also did not alter aggression in either species in either behavioral test. Overall, these results suggest that AVP may be more likely to be associated with offensive aggression as measured in the R‐I test than with neutral arena aggression and that the effects of AVP manipulations may differ between monogamous and non‐monogamous rodents.
