Previous research using a conditioned-attention paradigm demonstrated that 4-month-old infants of depressed mothers (a) failed to acquire associations when a segment of their mothers' infant-directed (ID) speech signaled the presentation of a smiling face but (b) did acquire associations when a segment of an unfamiliar nondepressed mother's ID speech signaled the face (P. S. Kaplan, J. -A. Bachorowski, M. J. Smoski, & W. J. Hudenko, 2002). In the present study, 5- to 13-month-old infants of depressed mothers failed to acquire associations when either their own mothers' (Experiment 1) or an unfamiliar nondepressed mother's (Experiments 1 and 2) ID speech signaled a face. However, these infants acquired associations when a segment of an unfamiliar nondepressed father's ID speech served as the signal (Experiment 2). One possible explanation of these results is that infants of depressed mothers selectively "tune out" ID speech from their mothers and from other, nondepressed, women. 相似文献

The affective underpinnings of job perceptions and attitudes: a meta-analytic review and integration 总被引:6,自引:0,他引:6
Using psychometric meta-analysis, the authors present a quantitative and qualitative review (k = 205, total pairwise N = 62,527) of the literature relating trait and state positive affect (PA) and negative affect (NA) to job-related attitudes, including job satisfaction, organizational commitment, turnover intentions, and dimensions of job burnout. Results indicated substantial correlations, ranging in absolute value from -.17 (PA and turnover intentions; NA and personal accomplishment) to.54 (NA and emotional exhaustion). Correlational results largely were consistent across hypothesized and exploratory moderator conditions. Meta-analytic multiple regression results generally supported the unique contribution of each affect to each attitude variable of interest. Implications and suggestions for future research on emotion-related aspects of job attitudes are discussed. 相似文献

This research demonstrates the usefulness of the technique of Smallest Space Analysis (SSA) in the construction of indices
of the experience of autonomy, a central construct in Ryan and Deci’s self-determination theory of motivation and personality
(SDT, 2000) and a construct central to recent controversies on socialization in different cultures. We propose that SSA has
two advantages in comparison to correlation tables in the assessment of the experience of autonomy. First, it allows easy
identification of items that best capture the various motivations along the relative autonomy continuum postulated by SDT.
Second, and more important, it can reveal data patterns that might contribute to theoretical refinement that otherwise might
remain unnoticed. These advantages were demonstrated in three Israeli samples: two samples of elementary school children (n = 697 and n = 417), and one sample of high school students (n = 317). Discussion considers ways in which SSA can contribute to the development and refinement of measures and theory pertaining
to the experience of autonomy in cultures and contexts not examined so far.

There are few (if any) population-based prospective studies that provide information on factors associated with temporal sequencing of suicide. In this prospective population-based study, the National Health Interview Survey (NHIS), 1986-1994, was linked to the National Death Index (NDI), 1986-1997, to assess factors that predict recent (within 12 months of interview, termed sooner) suicide versus suicide further in the future (more than 12 months after interview, termed later). Of the 653 completed suicides in the NHIS cohort, 13.4 percent completed suicide within a year of interview, and 86.6 percent did so after a year. Sooner decedents were more likely to be White, less educated, unemployed, and to use firearms than any other method compared with later decedents. Surprisingly, sooner decedents had higher levels of self-rated health at baseline. These results have substantial implications for clinicians and other professionals who interact with people at highest risk of suicide. Unfortunately, it may be unrealistic to expect that health care providers can modify the behavior of individuals at highest risk of suicide. 相似文献

Proposed somatic cell gene-therapies (especially those involving in utero therapies) may involve a small risk of germ-line modifications; this risk has engendered serious concern, and arguments have been made that such therapies ought not be pursued if such risks exists. We argue here that while pursuing deliberate germ-line modifications in humans would be inappropriate given the current state of the art, the risk of accidental germ-line modifications from most currently proposed in utero gene therapy is no different in kind or degree from other risks regularly taken in medical procedures. Given the possible benefits of such therapies, we argue that the risk of accidental germ-line modifications is well worth taking in these cases. 相似文献
