Responses of 4-month-old infants to hidden people and objects were investigated with equated task demands. Twenty-one 4-month-old infants were administered a combined task, in which they were shown a sounding stimulus that continued to sound after hiding, an auditory task, in which sound was the only source of information about the position of the object in space, and a vision task, in which a silent stimulus was shown to the infants prior to hiding. Five infant behaviours were coded: reaching, gazing, body movements, vocalizations and smiles. The infants reached significantly more for hidden objects than for people, to whom they vocalized instead. They further smiled, and moved their bodies more towards their invisible mother than to the other stimuli. Thus infants responded differentially to people and objects whether the stimuli were soundless (so that there was no cue to their presence) or not. This suggested that infants appreciated (a) that an object had been hidden; (b) this object was either animate or inanimate; and (c) different procedures were appropriate for the retrieval of, or for interacting with animate and inanimate objects. Discussion centres on the underlying representational system that allows for such appreciation.  相似文献

Among the many images and symbols of the Church which the church Fathers used, biblical mothers had an important role. Some of these images, such as Mary as an image of the Church, became widespread and have influenced later Christian theology and iconography. In this article, both the development and different applications of these images will be explored. How and to what purpose these images were used in the Early Church will also be studied. Among the topics dealt with by using these images were the origin, age, character and purpose of the Church, as well as its relation to several ‘others’ (the Jews, the schismatics and the heretics). In modern ecclesiological discussions, especially of Eve and Mary as images of the Church, the role of the Church in salvation, as well as the communal interpretation of biblical mothers, are relevant.  相似文献

The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.  相似文献

The purpose of this study was to describe maternal representations of the twin sibling relationship and of the children's differences and similarities. Mothers' mental representations were also analyzed with regard to two aspects of their child-raising attitudes: individualization of childcare routines, and the question of differentiation by “external signs of twinship” (dress, toys, and first names). Data from interviews with 44 mothers of twins conducted 13 months after the birth were analyzed in terms of 8 categories—complicity, rivalry/jealousy, agonistic relations, dominance, imitation, physical appearance, development, and personality. A multiple correspondence analysis of the data pointed out that the first dimension describing the mothers' representations concerns the contrast between the “unalike” representation of dizygotic twins and the “alike” representation of monozygotic twins. The second dimension corresponds to the casual, twinship-minimizing representations generated by the twin condition. Two other dimensions express the issues of aggression and dominance. The relationship between the child-raising behavior of the mothers and their representations of the twin couple turned out to be more complex than expected. The results are discussed in terms of the specificity of the psychological issues facing mothers of twins. Defense mechanisms used by some mothers to cope with the exceptional nature of the twin phenomenon are also suggested. © 1998 Michigan Association for Infant Mental Health  相似文献

A sequence of analytic sessions of a professional woman in her forties is used to illustrate the moving along process. The material shows a gradual change, where the patient's experience of her sense of agency is altered through a particular kind of interactive sequence. The example is intended to make it clear that the group's view of how change occurs is not strictly or primarily in terms of sudden changes, and that the problem of assessing moments of meeting as well as quantitative and qualitative shifts is one with which the group continues to struggle. © 1998 Michigan Association for Infant Mental Health  相似文献

Evidence suggests that conjoint treatment can be effective for certain violent couples in certain situations (Finkel in Rev Gen Psychol 11:193–207, 2007; LaTaillade et al. in J Cogn Psychother 20:393–410, 2006; Fals-Stewart et al. in J Consult Clin Psych 73:239–248, 2005; Stith et al. in J Marital Fam Ther 29(3):407–426, 2003). However, not as much is known about which aspects of conjoint treatment make a difference, nor if male and female participants experience these elements of treatment differently. Knowing which components of couples’ treatment clients perceive as helpful—and whether their perceptions differ by gender—will allow us to redefine models with an eye toward making them more effective. In this study we used qualitative methods to examine the aspects of a particular couples’ treatment program (Stith and McCollum in Aggress Violent Beh 16(4):312–318, 2011) that clients found useful while also considering the differences between men’s and women’s responses. Fourteen couples, in which the male had been identified as the primary aggressor, were interviewed multiple times to gain their perspectives about components of the program they found helpful and their suggestions for program improvement. Themes are analyzed by gender. Implications for treatment and future research are provided.  相似文献

Adolescents from three Italian cities responded to a questionnaire concerning the particular peer-group with which they were associated and identification with their family, aspects of the process of coping with seven developmental tasks, and demographic characteristics. The participants were 1600 male and female teenagers, with a mean age of 16.28 years, who were approached at schools and various meeting places in three Italian cities. The study shows that effective coping with developmental tasks depends largely on the degree of identification with both family and peer-group. Those who identify with both social groupings show advantages in various critical situations. Adolescents only identifying with either family or peers get emotional and instrumental support from that group but not from the other, thus, they are supported in some critical situations but not in others. Adolescents who are unwilling or unable to identify with their family and/or their peers are less successful in managing the transition to adulthood than others who are close to their parents and peers. Consistent with the findings of previous studies, the type of group adolescents join, be it a formal group or an informal street group, has no significant effect on their coping strategies.  相似文献
