Forty mothers whose preterm infants were about to be discharged from the Neonatal Intermediate Care Nursery (NICU) were randomly assigned to two groups: the first group of mothers conducted preterm infant massage and the second group only observed their preterm infants receiving massage. Both groups of mothers had lower depressed mood scores following the session. However, only the group who massaged their infants had lower anxiety scores after the session.  相似文献

A purported replication by P. G. Roma, A. Silberberg, A. M. Ruggiero, and S. J. Suomi of the authors' previous study claims to contradict their finding that capuchin monkeys (Cebus apella) refuse to exchange with an experimenter if their partner receives a superior reward. Roma et al. used no exchange task, however, or any other task. Roma et al. offered frustration as explanation of their findings, yet failed to statistically prove that the effect of frustration is stronger than that of inequity. They also misrepresented the dependent measure of the authors' study. Reanalysis of the authors' own data indicated no role of frustration, that is, no effect of previous experience with a superior reward. The authors conclude that Roma et al.'s study is not a replication and does not disprove the authors' findings.  相似文献

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical abuse, many participants reporting abusive acts on the CAMI scored below the cut-point for physical abuse on the CTQ. Classification differences for both types of abuse were largely unrelated to demographic factors, socially desirable responding, or self-reported withholding of information. The implications of these results are discussed in light of future research using retrospective methods of assessing childhood abuse.  相似文献

  • This paper is focused on a study designed to investigate loyalty in retail banking. The research findings suggest that loyalty is the outcome of a cognitive rather than an affective process. The main antecedents of bank loyalty were found to be perceived value, service quality, service attributes, satisfaction, image and trust: constructs that are inter‐related and form a network of loyalty antecedents.

Playboy's portrayal of the male ideal of feminine beauty, in terms of overall body size, percent normative weight, and waist-to-hip ratios (WHRs), was analyzed for the years 1979–1999. Trends were examined through body measurements obtained from Playboy centerfolds. Results reveal a continuation of the low body mass index (BMI) found in the Playmates by earlier studies; however, for the 21 years examined, the trend towards increasing thinness seems to have stabilized and may have begun to actually reverse. There was also an increase in the centerfolds’ WHRs over the 21-year time period. Overall, the results support the continued valuing in American society of a thin ideal for women; while the images of beauty have become somewhat heavier over the 21-year period reviewed, the Playmates remain markedly below weights normative for their age group.  相似文献

OBJECTIVE: To determine if cues help young children discriminate among thoughts, feelings and behaviours. PARTICIPANTS: Ninety-six children aged 4-7 years from three schools in Norwich, UK. DESIGN: Within each age band (4, 5, 6, 7), children were randomised to the cue or the no cue condition on a stratified basis ensuring that equal numbers of boys and girls from each school were in each of the eight cells (cue condition x age). Cues were glove puppets and post boxes. The effect of IQ was controlled. MEASURES: A discrimination task, in which children were asked to identify a thought, a feeling and a behaviour from each of six brief stories, and a brief IQ assessment were administered to children individually. RESULTS: There was a significant effect of age and cue condition on performance; older children and those who were presented with the cue performed better. There were no gender differences and no interaction between cue condition and age. CONCLUSION: Many young children discriminated among thoughts, feelings and behaviours suggesting that they may be able to engage in this aspect of cognitive behaviour therapy. Simple cues (puppets and posting boxes) improved children's performance and these may be useful therapeutic tools with young children.  相似文献

This paper presents the Featural and Unitary Semantic Space (FUSS) hypothesis of the meanings of object and action words. The hypothesis, implemented in a statistical model, is based on the following assumptions: First, it is assumed that the meanings of words are grounded in conceptual featural representations, some of which are organized according to modality. Second, it is assumed that conceptual featural representations are bound into lexico-semantic representations that provide an interface between conceptual knowledge and other linguistic information (syntax and phonology). Finally, the FUSS model employs the same principles and tools for objects and actions, modeling both domains in a single semantic space. We assess the plausibility of the model by showing that it can capture generalizations presented in the literature, in particular those related to category-related deficits, and show that it can predict semantic effects in behavioral experiments for object and action words better than other models such as Latent Semantic Analysis (Landauer & Dumais, 1997) and similarity metrics derived from Wordnet (Miller & Fellbaum, 1991).  相似文献

The speech of people with Parkinson's disease is often unintelligible because the speaker has limited volume and imprecisely articulated speech. The Lee Silverman Voice Treatment addresses volume by requiring a patient to exert extreme effort to adduct the vocal folds and increase volume. Little attention, however, is paid to articulation. Such patients often have perceptual difficulties which prevent them from monitoring their own volume and speech. A case study presents a method for improving volume and articulation of speech of a patient with Parkinson's disease by focusing on perceptual aspects of speech.  相似文献
