Two studies measured the facial prominence of women and men in popular images over the last decade. The first study used 1,200 photo-graphs from Time and Newsweek for the years 1970 and 1980. The results indicate that overall, men have received greater facial prominence than women, and facial prominence has increased over the decade. Only for Newsweek did women show a significantly greater increase in facial prominence than men. The second study used 640 photographs from Good Housekeeping and Ms. for the years 1974 and 1984. The results show that overall, men have received greater facial prominence than women, and facial prominence has risen over the decade, although not by much. In Ms. , women but not men gained; in Good Housekeeping , women gained slightly, but not as much as men. The results are consistent with earlier reports of an asymmetry in representation of men's and women's faces and suggest that this asymmetry is slowly diminishing. 相似文献

In certain species of nonhibernating rodents, although young nestlings cease breathing and heart action when their body temperature is lowered to near freezing, the nestlings need only be rewarmed to recover. This remarkable capacity for immediate recovery has been known many years, but long-range consequences of deep neonatal hypothermia have never before been investigated. Mice (Peromyscus leucopus) that had been exposed to four 2.5-hr episodes of deep (2-4 degrees C) hypothermia when 4-10 days old were later compared with littermate controls in their performance on two learning tasks. The two groups did not differ in their acquisition or extinction of a lithium-induced learned taste aversion to sucrose. Nor did they differ in learning to find a hidden platform in a swimming pool. Thus in a nonhibernating rodent species, deep hypothermia experienced neonatally--unlike similar hypothermia administered in adulthood--seems not to induce deficits in subsequent learning capabilities. The resistance of neonates to damage probably represents an adaptation, for their modest thermoregulatory abilities render them vulnerable to deep hypothermia in frigid environments. 相似文献

Less tangible types of social support (emotional, informational, and companionship) were shown to predict reports of physical symptoms as a joint function of both affiliative need and negative life events, while the effects of tangible support depended only upon the occurrence of negative life events (the prototypical buffering effect). Low affiliative need individuals tended to benefit from both types of support, while high affiliative need individuals benefited primarily from more tangible support. The results were discussed in terms of the proposal that low affiliative need individuals hold a more problem-focused view of social support, while high affiliative need individuals tend to take a less personally instrumental stance toward interpersonal interaction. 相似文献

Forty-eight undergraduates made lexical decisions about emotionally aversive and nonemotional words. Emotionally aversive
target words were preceded either by an emotionally aversive prime word, a nonemotional but semantically related prime or
a nonemotional and semantically unrelated prime. Nonemotional targets were preceded by nonemotional primes which were either
semantically related to targets, unrelated, or neutral (strings of Xs). Primes were presented for 50 ms to one group of 16
participants, 500 ms to a second group and 1250 ms to a third group. Measurement of lexical decision time showed significant
semantic primary effects for nonemotional targets, and these were not influenced by prime duration. Priming effects for emotionally
aversive targets due both to emotional and nonemotional relatedness of primes and targets were also found and these effects
were not influenced by prime duration. The results are considered to be consistent with Bower’s (1981) associative network
theory of memory, and possible clinical implications for explaining spontaneous panic attacks and the incubation of anxiety
are discussed. 相似文献

Nonconscious acquisition of information. 总被引:7,自引:0,他引:7
The authors review and summarize evidence for the process of acquisition of information outside of conscious awareness (covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). Data indicate that as compared with consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but are also structurally more sophisticated, in that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of nonconscious acquisition of information provide a major channel for the development of procedural knowledge that is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering of emotional reactions. 相似文献

This article provides a brief review of the basic principles of social exchange theory with an emphasis on a social exchange model of conflict. The key concepts of justice, reciprocity, and equity comprised in social exchange theory are addressed from a social and theological perspective. 相似文献

Health educators proposing alcohol prevention programs for a church setting face a variety of problems. Information only preventive types of alcohol programs are being increasingly criticized. The purpose of this study was to identify variables that best predict use of alcohol for children in fundamentalist Protestant Christian families. Three hundred and two students currently enrolled in a mandatory health course at a fundamentalist Protestant Christian university responded to a questionnaire designed to identify contextual or environmental risk factors for alcohol use. A significant difference was found in five of 15 established environmental factors. This paper suggests that an alcohol education program that focused on these differences would be advantageous for the health educator to carry out in the church setting. 相似文献

When places are explored without vision, observers go from temporally sequenced, circuitous inputs available along walks to knowledge of spatial structure (i.e., straight-line distances and directions characterizing the simultaneous arrangement of the objects passed along the way). Studies show that a life history of vision helps develop nonvisual sensitivity, but they are unspecific on the formative experiences or the underlying processes. This study compared judgments of straight-line distances and directions among landmarks in a familiar area of town by partially sighted persons who varied in types and ages of visual impairment. Those with early childhood loss of broad-field vision and those blind from birth performed significantly worse than those with early or late acuity loss and those with late field loss. Broad-field visual experience facilitates perceptual development by providing a basis for proprioceptive and efferent information from locomotion against distances and directions relative to the surrounding environment. Differences in the perception of walking, in turn, cause the observed differences in sensitivity to spatial structure. 相似文献

We examined the longitudinal adjustment, from grade 4 to grade 11, of a sample (n = 76) of boys judged to be at-risk for developing antisocial behavior patterns. We also examined subgroups of the sample differentiated by risk status and arrest records at grade 11. Antisocial behavior patterns exhibited by these boys demonstrated considerable stability over time. Differences were noted among high and lower-risk groups who were and were not arrested. In particular, measures of academic and social skills dimensions were related to better overall adjustment as indicated by lower arrest rates. Implications of these results for intervention are presented. 相似文献

A detailed analysis was made of the data of a previous paper by Bliss et al (1966). That paper describes a series of experiments, in which 2 to 12 simultaneous air-jet stimuli were presented on the 24 phalanges of both hands. In addition, new data from an early blind S, whose performance was significantly better, is compared to the data of the original four Ss. Memory properties of all five Ss estimated by whole- and partial-reporting techniques gave evidence for a tactile short-term memory that (1) has a duration of a few seconds, (2) varies considerably in size (but not in temporal characteristics) for different Ss, and (3) has a capacity limited by spatial resolution. Tactile masking did not account for the limited spatial resolution, but a stimulus-spreading (or lateral-excitation) model did. 相似文献
