The present study introduces a balanced survey of a range of behavioral and emotional experiences to assess impressions of
a person’s childhood. Ninety-one undergraduates and 70 of their parents rated exposure to positive and negative social and
solitary experiences. The survey demonstrated acceptable internal consistency and 4-week test–retest reliability, and scores
correlated with Zimbardo’s Time Perspective Inventory of temporally based beliefs and values, Batcho’s inventory of personal
nostalgia, and Holbrook’s measure of historical nostalgia. Correlations with time perspective and nostalgia inventories suggest
that favorable impressions of childhood are associated with benefits such as social connectedness, personal continuity, and
health-promoting behaviors and adverse impressions with less adaptive impacts such as unsatisfactory relationships, discontinuity,
and distress. Ratings of social experiences were correlated more closely with childhood happiness than were solitary experiences.
The Childhood Survey shows promise as a tool to expand the exploration of childhood experiences beyond adverse events to encompass
components that comprise a happy childhood. 相似文献
In the current study we examined the relationship between working memory capacity, inhibition/susceptibility to interference and fluid intelligence, measured by the Raven's Progressive Matrices (PM38), comparing groups of young (aged 18–35), young-old (aged 65–74), and old-old (aged 75–86) participants. Groups were administered two working memory tasks tapping into different mechanisms involved in working memory. The ability to control for irrelevant information was measured both considering memory errors (intrusion errors) in a working memory task and an index of susceptibility to interference obtained with a variant of the Brown-Peterson task. Regression analyses showed that the classical working memory measure was the most potent predictors of the Raven's score. Susceptibility to interference and intrusions errors contributed, but to a lower extent, to the Raven explained variance. These results confirm that working memory shares cognitive aspects with the fluid intelligence measure considered, whereas the role of inhibition to Raven scores is still in need of better evidence. 相似文献
The purpose of these experiments was to investigate an aspect of autonomic activity (namely, skin resistance) during the course of eyelid conditioning, as a check on those theories which postulate that ‘arousal’ or ‘emotionality’, as measured by autonomic activity, is related to the level of conditioning.
Although many measures of skin resistance were obtained (including both basal levels and responses), the results were with one exception entirely negative in showing no significant correlations between the autonomic variables and eyelid conditioning. The exception was a significant correlation between skin resistance change to a test-trial puff of air (the UCS) and the level of eyelid conditioning reached by the subject; this result supports predictions made by Spence about the role of a hypothetical emotional response in conditioning, but was obtained in only one of the two studies.
The generally non-significant relationship between skin resistance and eyelid conditioning is discussed with respect to response specificity, and also to a postulated specificity in conditioning such that a subject who conditions well in one modality does not necessarily condition well in another modality. This specificity is considered in the light of the physiological mechanisms involved in each response system. 相似文献
In this article, we review family therapy's history regarding community concerns and broader societal issues; offer a model of levels of therapists' involvement with communities and community systems; and propose that family therapists join the citizen activation movement by becoming catalytic partners with families in communities. We call for a new kind of community practice that is driven less by therapist-defined problems and professional expertise, and more by community-defined problems and families' own expertise. 相似文献
Free recall and recognition, memory for temporal order, spatial memory and prospective memory were assessed in patients with frontal lobe lesions, patients with posterior cortex lesions and control subjects. Both patient groups showed equivalent memory deficits relative to control subjects on a range of free recall and recognition tasks, on memory for temporal order and on a prospective memory task. The patient groups also performed equivalently on the spatial memory task although only patients with frontal lobe lesions were significantly impaired. However, the patients with frontal lobe lesions showed an increased false alarm rate and made more intrusion errors relative not only to the control subjects, but also to the patients with poster or cortex lesions. These memory problems are discussed in relation to deficits in executive function and basic memory processes. 相似文献
A grey parrot (Psittacus erithacus), able to label the color of the bigger or smaller object in a pair (I. M. Pepperberg & M. V. Brezinsky, 1991), to vocally quantify < or =6 item sets (including heterogeneous subsets; I. M. Pepperberg, 1994), and separately trained to identify Arabic numerals 1-6 with the same vocal English labels but not to associate Arabic numbers with their relevant physical quantities, was shown pairs of Arabic numbers or an Arabic numeral and a set of objects and was asked for the color of the bigger or smaller one. The parrot's success showed he (a) understood number symbols as abstract representations of real-world collections, (b) inferred the relationship between the Arabic number and the quantity via stimulus equivalence, and (c) understood the ordinal relationship of his numbers. 相似文献
In addition to its primary linguistic function, the Hebrew alphabet is sometimes used as a means of number notation (i.e.,
the system of gematria). Hebrew letters, Arabic numerals, Hebrew number names, and Hebrew letter names were used in a numerical
size comparison task, in which two visually presented symbols were compared for numerical value while irrelevant variations
in their physical size had to be ignored. A size congruity effect, indicated by faster responses when differences in physical
and numerical size were consistent, was larger for Arabic numerals than for number names. The effect for Hebrew letters was
similar to that for Arabic numerals and was stronger than that observed for letter names. These results suggest flexible processing
of Hebrew letters, so that they function as ideographic symbols in an arithmetic context. A distance effect, indicated by
an inverse relationship between reaction time and numerical distance, was found for all notations but was particularly strong
for Hebrew letters. 相似文献
The extent to which humans and nonhumans share numerical competency is a matter of debate. Some researchers argue that nonhumans, lacking human language, possess only a simple understanding of small quantities, generally less than four. Animals that have, however, received some training in human communication systems might demonstrate abilities intermediate between those of untrained nonhumans and humans. Here I review data for a Grey parrot (Psittacus erithacus) that has been shown to quantify sets of up to and including six items (including heterogeneous subsets) using vocal English labels, to comprehend these labels fully, and to have a zero-like concept. Recent research demonstrates that he can also sum small quantities. His success shows that he understands number symbols as abstract representations of real-world collections, and that his sense of number compares favorably to that of chimpanzees and young human children. 相似文献
Simulations examined the hypothesis that small samples can provide better grounds for inferring the existence of a population correlation, p, than can large samples. Samples of 5, 7, 10, 15, or 30 data pairs were drawn either from a population with p=0 or from one with p>0. When decision accuracy was assessed independently for each level of the decision criterion, there was a criterion-specific small-sample advantage. For liberal criteria, accuracy was greater for large than for small samples, but for conservative criteria, the opposite result occurred. There was no small-sample advantage when accuracy was measured as the area under a receiver operating characteristic curve or as the posterior probability of a hit. The results show that small-sample advantages can occur, but under limited conditions. 相似文献
The purpose of our study is to assess the emotional responses to disclosing APO E genotype to asymptomatic older adults at increased risk for Alzheimer disease (AD). This is a longitudinal cohort study of volunteer subjects who were aged 50 years or over, asymptomatic for (AD), had a family history of AD, passed a psychological assessment, and participated in pre- and post-test genetic counseling and three follow-up visits over 10 months. We analyzed responses by three emotional constructs: depressed, worried, and relieved. Three hundred and twenty-eight subjects were screened, 76 received their APO E genotype. When emotional responses occurred it was immediate, between baseline and the 1 month follow-up. Emotional reactions did not change significantly past 1 month. Our results suggest that for emotionally stable persons, disclosing results of their APO E genotype, high risk subjects did not report more depression or worry and low risk subjects felt relieved by knowing the results. Future studies should evaluate the risks of disclosure to family members involved in the diagnostic work-up of a relative and include subjects from a broader range of emotional stability and socioeconomic background. 相似文献
