Research and theory distinguish two types of attitude: automatic evaluative reactions and deliberate evaluative judgments, referred to as implicit and explicit attitudes, respectively. Although these attitudes are distinct, they may influence each other. Four studies tested whether implicit and explicit attitudes are both influenced by propositional and associative learning. We also tested whether changes in one kind of attitude mediate changes in the other. Study 1 found that propositional learning about novel individuals directly influenced explicit attitudes and indirectly influenced implicit attitudes through changes in explicit attitudes. Studies 2 and 3 replicated this finding and extended it by simultaneously demonstrating that associative learning through Evaluative Conditioning directly influences implicit attitudes and indirectly influences explicit attitudes through changes in implicit attitudes. Study 4 replicated these effects for attitudes toward familiar, rather than novel, targets. These results suggest that implicit and explicit attitudes can share common antecedents and influence each other. 相似文献

We studied 9,220 children referred to a comprehensive mental health crisis stabilization program to examine the impact of
caregiver capacity on crisis worker decisions to refer children for intensive community-based treatment as opposed to inpatient
psychiatric hospitalization. Due to the different role of caregivers in the child welfare system, analyses were stratified
by state custody status. Among both groups, there was a significant inverse association between child mental health need and
referral to intensive community-based treatment. For children not in state custody with low mental health need, there was
no difference in the likelihood of referral to intensive community-based treatment across levels of caregiver capacity. However,
for children not in state custody with medium and high mental health needs, those whose caregivers were deficient or severely
deficient were significantly more likely to be referred for intensive community-based treatment than were those who had capable
caregivers. Multivariate analyses demonstrated similar results after controlling for potential confounding variables and confirmed
that caregiver capacity contributes significantly to the logistic model’s classification accuracy. Results suggest further
investigation of the impact of caregiver capacity on mental health crisis worker referral decisions is needed. 相似文献

Subjects viewed a foveally stabilized target presented against a background field of dots moving sinusoidally. Several different modes of viewing the target were used (subjects were instructed to gaze, look, or hold), and the frequency of sinusoidal field motion was varied from 1/32 to 2 Hz. In line with previous findings, the presence of a stabilized target resulted in substantial suppression of optokinesis. The characteristics of this suppression (gain and phase of slow residual eye movements) were dependent on both the mode of viewing the target and the frequency of field motion. When subjects used an imaginary target, little suppression occurred. These findings provide an overall profile of dynamic characteristics of mechanisms involved in the suppression of optokinesis. They support the view that this suppression is significantly determined by the presence of a target against a moving background (even without retinal slip), and by the mode of attending to the target. 相似文献

Recent advances in medical technology have led to a marked improvement in the chances of survival of sick or preterm infants, thereby stimulating renewed ethical debate on the status of the newborn. Two contradictory attitudes to the medical care of preterm or congenitally malformed newborn infants can be discerned in our pluralistic society. The two attitudes have their historical roots in the classical Graeco-Roman and Judaeo-Christian ethical traditions respectively. The former views newborn infants as of potential value only whereas the latter emphasises the intrinsic worth and dignity of the individual made in God's image. Recent secular philosophical reflection has provided a rationale for infanticide of the sick or abnormal newborn. A Christian approach to the care of the newborn prohibits intentional killing yet may encompass the withdrawal of treatment that is inappropriate or unduly burdensome. Medical care should be based upon respect for the value of the individual, protection of the defenceless from abuse or exploitation, and wise stewardship of limited health-care resources. 相似文献
