In complex navigation using landmarks, an animal must discriminate between potential cues and show context (condition) sensitivity. Such conditional discrimination is considered a form of complex learning and has been associated primarily with vertebrates. We tested the hypothesis that octopuses and cuttlefish are capable of conditional discrimination. Subjects were trained in two maze configurations (the conditions) in which they were required to select one of two particular escape routes within each maze (the discrimination). Conditional discrimination could be demonstrated by selecting the correct escape route in each maze. Six of ten mud-flat octopuses (Octopus bimaculoides), 6 of 13 pharaoh cuttlefish (Sepia pharaonis), and one of four common cuttlefish (S. officinalis) demonstrated conditional discrimination by successfully solving both mazes. These experiments demonstrate that cephalopods are capable of conditional discrimination and extend the limits of invertebrate complex learning. 相似文献

Eighty-two families with noncompliant, aggressive children participated in a behavioral parent training program to modify dysfunctional family relationships. At follow-ups ranging from 1 to 3 yr, each family was assigned to one of two groups according to its treatment outcome status (success, no success). The groups were then compared on eight measures of social and material standing found to be predictive of outcome in previous research, and on two measures of parental involvement in treatment assumed to act as process variables which may account for the relationship between social and material standing and outcome. Contrary to prediction, the measures of parental involvement failed to account for any significant amount of variance in outcome. Many families characterized by severe adverse social and material conditions may be unable to benefit from behavioral parent training, regardless of the extent to which they participate in treatment. Possible clinical and theoretical implications are briefly discussed. 相似文献

The process of coping among ethnic minority first-generation college freshmen: a narrative approach 总被引:6,自引:0,他引:6
Using a narrative approach, the authors explored the process of coping among ethnic minority college students. Participants were 30 freshmen, predominantly the 1st members of their families to attend college, who wrote journals once a week for 3 weeks on their ways of coping with stress. They also completed a survey of background information. Those who were more successful in coping, compared to those who were less successful, expressed a greater sense of self-efficacy and did not feel that they lacked needed social support. However, those who were more successful in coping did not differ on demographic variables, including ethnicity, gender, country of birth, and parental education. The narratives provide evidence of the complex and interactive process of coping among ethnic minority college students. 相似文献

The present study examined whether, for older adults, a verbal or imagery cognitive style is associated with recall of names and faces learned in an experimental condition. Cognitive abilities that are represented in current models of face recognition and name recall were also examined. Those abilities included picture naming, verbal fluency (i.e., naming items within a given category), vocabulary comprehension, visual memory, and the learning of unassociated word pairs. Fifty older adults attempted to learn first and last names of 20 student actors and actresses pictured on videotapes (40 names total). On average, participants learned the most first names, followed by last names, and the fewest full names. The greater the number of responses on a questionnaire associated with an imagery cognitive style, the more the names of faces were correctly identified by participants. There was no significant relationship between a verbal cognitive style and the number of names and faces recalled. As for cognitive abilities, all of the abilities measured—with the exception of vocabulary comprehension—were significantly associated with the number of names and faces learned. A regression analysis indicated that the best predictor of successful name-face learning was the participants' ability to learn and recall 5 unrelated word pairs. When that cognitive measure was deleted from the regression analysis, delayed visual memory and verbal fluency were the next best predictors of the older adults' ability to learn names and faces. 相似文献
