Infant sensitivity to kinetic information specifying three-dimensional object shape was assessed using computer-generated random-dot displays. Four-month-old infants were habituated to displays of an object oscillating about two different axes on alternating trials. Following habituation, the infants were tested for recovery from habituation to a display of the same object and a novel object. Both test displays employed a new axis of rotation. The infants generalized habituation to the same object and increased their looking to the new object. These results provide evidence that infants are sensitive to motion-carried information specifying three-dimensional object shape, since the random-dot displays minimized static information that differentiated the two objects. These findings suggest that, at least by 4 months of age, infants can detect subtle differences in shape from purely kinetic information. 相似文献

There is increased evidence that infants who receive poor quality social stimulation from their primary caregiver are at risk for later developmental difficulties. This paper describes a preventive intervention for mother-infant dyads exhibiting impaired patterns of social interaction. An impaired relationship with the primary caregiver has been found to be associated with social and emotional deficits in early childhood as well as with significant psychopathology in adulthood. The intervention consisted of group treatment of mothers and their infants. Each group session has 4 subsections which, together, were directed towards improving the mothers' ability to relate in a stimulating and nurturant manner to their children. Types of intervention included didactic instruction, modeling, and interpretation of the infant's behavior. Qualitative data suggested that the group intervention has positive effects on the mother-infant dyads. 相似文献

A radiotelemetry system for continuous monitoring of the temperature and/or location of small animals is described. All the functions of system control are carried out by an on-line microcomputer (TRS-80 Model III), resulting in a versatile system capable of alternating recording the temperature/location of multiple subjects with other behavioral or physiological events, such as activity level. We describe the use of this system in monitoring body temperature in hamsters and in recording the incubation pattern of breeding ring doves. 相似文献

Both theoretical arguments and laboratory evidence indicate that society awards earned dignity (worth) to persons perceived as voluntarily performing praiseworthy behaviors. Laboratory research, as well as common observation, indicates also that society accords an intrinsic dignity unconditionally to all people. On a questionnaire given in class, college students reported increased dignity earned by the Russians from their praiseworthy (i.e., embracing freedom) and voluntary rejection of the attempted coup in 1991. The questionnaire also revealed a general belief in intrinsic dignity. External evidence for earned dignity is shown by increased international support for the Russians after rejection of the coup. This convergence of laboratory and external data validates the laboratory techniques for studying social perception of human dignity. 相似文献

This study was conducted to investigate the effect of sexual stereotyping on the exercise of authority. The hypotheses were that the sexual composition of the group affects the authority behavior of group leaders when the task has low clarity but that sex characteristics have no effect on authority behavior when the task has high clarity. These predictions were expected to hold both in situations where there is a direct association between sex and the task ability and in situations where no such connection is established. As predicted, no significant difference was found in the number of high control acts made by male and female leaders in the high task clarity conditions, even when sex was directly related to the task ability. Also as hypothesized, sex effects did operate strongly in the low task clarity conditions. Male leaders made significantly more high control acts than female leaders, even in conditions where no prior relation was established between sex and the task ability. Thus, these results indicate that the effect of sex characteristics on the exercise of authority is enhanced in low task clarity situations and is neutralized in high task clarity situations.A preliminary version of this paaper was presented at the West Coast Conference for Small Group Research, San Francisco, California, April 24, 1974.

Factors affecting word retrieval were compared in a timed picture-naming paradigm for 520 drawings of objects. In prior timed
and untimed studies by Snodgrass and Vanderwart (1980) and Snodgrass and Yuditsky (1996), concerns were raised that participants
could not reliably name large numbers of items in a single session. We show that reliable results are obtained in a single
session for 520 items and validate our method against previous findings by Snodgrass and colleagues for overlapping items.
For these items, comparable levels of name agreement and latency are obtained, and we replicate effects of length, frequency,
both objective and subjective age of acquisition, and visual complexity on reaction time (RT) and name agreement measures.
Name agreement is unaffected by order of presentation, although there is a gradual increase in RTs across the session, requiring
use of multiple random orders. Current extensions of our method include cross-linguistic, bilingual, developmental, and neuropsychological
studies and comparisons of action naming and object naming. 相似文献

Adult-child interactions during stressful medical procedures were investigated in 43 pediatric patients videotaped during a venipuncture procedure in the course of cancer treatment. Relations among six adult behavior categories (explain, distract, command to engage in coping behavior, give control to the child, praise, and criticize/threat/bargain) and three child behavior categories (momentary distress, cry/scream, and cope) were examined using correlational and sequential analysis. Results indicated that adult distraction resulted in increased child coping and reduced momentary distress and crying. Adult explanations, although a likely response to child distress and crying, did not result in a reduction of these behaviors. Attempts to give the child control reduced child crying. Implications for clinical interventions during painful medical procedures are discussed. 相似文献
