Internal poverty and teen pregnancy 总被引:1,自引:0,他引:1
The subjects for the present study were drawn from the female students who participated in the National Education Longitudinal Study (NELS) initial eighth-grade data collection. Adolescent females who later became pregnant were matched on race, birth month, and birth year with adolescent females who did not report a pregnancy. The study examined selected predictor variables from the baseline 1988 wave of data in relation to the outcome variable of pregnancy status. Results indicated a statistically significant difference in locus of control between those females who later became pregnant and those who later did not experience a pregnancy during adolescence. Those who later became pregnant were much more likely to have an external locus of control (p = .0001). Females who later became pregnant were also more likely to have a poorer sense of personal efficacy (p = .0001). Finally, females who later experienced a teen pregnancy had more traditional occupational expectations (p = .006) and lower educational expectations (p = .001) than did those who did not later report a teen pregnancy. 相似文献

Caricaturing facial expressions 总被引:1,自引:0,他引:1
The physical differences between facial expressions (e.g. fear) and a reference norm (e.g. a neutral expression) were altered to produce photographic-quality caricatures. In Experiment 1, participants rated caricatures of fear, happiness and sadness for their intensity of these three emotions; a second group of participants rated how 'face-like' the caricatures appeared. With increasing levels of exaggeration the caricatures were rated as more emotionally intense, but less 'face-like'. Experiment 2 demonstrated a similar relationship between emotional intensity and level of caricature for six different facial expressions. Experiments 3 and 4 compared intensity ratings of facial expression caricatures prepared relative to a selection of reference norms - a neutral expression, an average expression, or a different facial expression (e.g. anger caricatured relative to fear). Each norm produced a linear relationship between caricature and rated intensity of emotion; this finding is inconsistent with two-dimensional models of the perceptual representation of facial expression. An exemplar-based multidimensional model is proposed as an alternative account. 相似文献

Ratio scaling was used to obtain from 5 subjects estimates of the subjective dissimilarity between the members of all possible pairs of 17 tactile surfaces. The stimuli were a diverse array of everyday surfaces, such as corduroy, sandpaper, and synthetic fur. The results were analyzed using the multidimensional scaling (MDS) program ALSCAL. There was substantial, but not complete, agreement across subjects in the spatial arrangement of perceived textures. Scree plots and multivariate analysis suggested that, for some subjects, a two-dimensional space was the optimal MDS solution, whereas for other subjects, a three-dimensional space was indicated. Subsequent to their dissimilarity scaling, subjects rated each stimulus on each of five adjective scales. Consistent with earlier research, two of these (rough/smooth and soft/hard) were robustly related to the space for all subjects. A third scale, sticky/slippery, was more variably related to the dissimilarity data: regressed into three-dimensional MDS space, it was angled steeply into the third dimension only for subjects whose scree plots favored a nonplanar solution. We conclude that the sticky/slippery dimension is perceptually weighted less than the rough/smooth and soft/hard dimensions, materially contributing to the structure of perceptual space only in some individuals. 相似文献

The temporal relations among candidate causes were studied in a causal induction task using a design that is known to produce occasion setting in animal learning preparations. For some subset of the observations, one event, the occasion setter, was accompanied by another event, the conditional cause; for another subset of the observations, the conditional cause occurred alone. The efficacy of the conditional cause depended on whether it was or was not accompanied by the occasion setter. Participants used the occasion setter to modulate their effect expectancy to the conditional cause when the events were presented serially, but not simultaneously. Current causal induction models are unable to account for the full range of effects that we observed; the relative roles of time, attention, and cue distinctiveness are discussed. 相似文献

Composite facial expressions were prepared by aligning the top half of one expression (e.g., anger) with the bottom half of another (e.g., happiness). Experiment 1 shows that participants are slower to identify the expression in either half of these composite images relative to a "noncomposite" control condition in which the 2 halves are misaligned. This parallels the composite effect for facial identity (A. W. Young, D. Hellawell, & D. C. Hay, 1987), and like its identity counterpart, the effect is disrupted by inverting the stimuli (Experiment 2). Experiment 3 shows that no composite effect is found when the top and bottom sections contain different models' faces posing the same expression; this serves to exclude many nonconfigural interpretations of the composite effect (e.g., that composites are more "attention-grabbing" than noncomposites). Finally, Experiment 4 demonstrates that the composite effects for identity and expression operate independently of one another. 相似文献

In 2 experiments involving computer-rendered versions of single shapes or "geons," the extent to which depth rotation affects the visual discrimination performance of pigeons in both go/no-go and forced-choice tasks was documented. The pigeons were able to recognize geons at most rotations in depth; however, the pigeons' recognition performance was better at the training view than at most other views. Aspects of these results are both consistent with and problematic for object-centered and viewer-centered theories of object recognition. 相似文献

Cytochrophin-4 (cyt-4), a tetrapeptide with opioid-like activity, caused amnesia when injected into chick forebrain 5 hr after passive-avoidance training. Bilateral injections of cyt-4 directly into the lobus parolfactorius (LPO) resulted in the chicks being amnesic for the training task 24 hr later, whereas unilateral injections of cyt-4 were effective only when injected into the right LPO. Cyt-4-induced amnesia was reversed by the general opioid antagonist, naloxone, indicating that cyt-4 was acting via an opioid receptor. The mu- and delta-opioid receptors (but not kappa-opioid or ORL(1)-receptors) have been shown to be involved in memory formation 5 hr after training (). Because an antagonist of the mu-opioid receptor inhibited memory, we attempted to reverse the effect of cyt-4 using mu-opioid receptor agonists. Met[enk] was unable to reverse the inhibition of memory formation by cyt-4 suggesting that the mu-opioid receptor is not involved in this effect. However endomorphin-2 (endo-2) reversed the effect of cyt-4. We further investigated the action of endo-2 using an irreversible antagonist of the mu-receptor, beta-funaltrexamine (beta-FAN), and found that endo-2 reversed beta-FAN-induced amnesia indicating that endo-2 was not acting on the mu-opioid receptor in the chick. Because unilateral injections of beta-FAN were not amnesic (bilateral injections were amnesic) this provided further evidence that the effect of cyt-4 was not mediated via the mu-opioid receptor. Coinjection of the delta-receptor agonist, (D-Pen(2), L-Pen(5))enkephalin (DPLPE), reversed the disruptive effect of cyt-4 on memory. However, memory modulation via the delta-opioid receptor was not lateralized to the right hemisphere suggesting that cyt-4 does not act via this receptor either. It was shown that an antagonist of the epsilon-opioid receptor inhibited memory at the 5 hr time point. We conclude that the epsilon-opioid receptor or an unidentified opioid receptor subtype could be involved in the action of cyt-4. 相似文献

Homophobia in the black community has been largely attributed to the Black Church's conservative views concerning sexual orientation. Prior research demonstrates that black congregations are generally nonaffirming of nonheterosexuality; however, few studies have investigated black congregants’ responses to their churches’ climates regarding sexuality. Using in-depth interviews, this paper examines the extent to which black Christians are content with their congregations’ nonaffirming climates. Findings indicate that although some black parishioners are content with or indifferent to their churches’ climates, most respondents advocate for a change in how their congregations address sexual orientation, specifically calling for open conversations about sexuality. Furthermore, an examination of the language respondents used to evaluate congregational climates suggests discussions of sexuality in churches that humanize and encourage empathy for nonheterosexual identities may help facilitate such conversations. These results challenge assumptions of ideological homogeneity within religious organizations and could inform strategies to promote nonheterosexual inclusion in congregations. 相似文献
