Infants learn less from a televised demonstration than from a live demonstration, the video deficit effect. The present study employs a novel approach, using touch screen technology to examine 15‐month olds' transfer of learning. Infants were randomly assigned either to within‐dimension (2D/2D or 3D/3D) or cross‐dimension (3D/2D or 2D/3D) conditions. For the within‐dimension conditions, an experimenter demonstrated an action by pushing a virtual button on a 2D screen or a real button on a 3D object. Infants were then given the opportunity to imitate using the same screen or object. For the 3D/2D condition, an experimenter demonstrated the action on the 3D object, and infants were given the opportunity to reproduce the action on a 2D touch screen (and vice versa for the 2D/3D condition). Infants produced significantly fewer target actions in the cross‐dimension conditions than in the within‐dimension conditions. These findings have important implications for infants' understanding and learning from 2D images and for their using 2D media as the basis of actions in the real world. 相似文献

Gender and history of suicidality (HS vs. NoHS) were related to current symptoms of depression, reasons for living, and reports of self-destructive and life-threatening behavior in a college student sample. Overall, college men reported engaging in more life-threatening and potentially suicidal behavior than college women on the Life Attitudes Schedule (LAS). No gender effects were obtained on the symptoms of depression and reasons for living measures. Results suggest that the LAS may be a particularly effective way to identify college students at risk for self-destructive and suicidal behavior. As expected, HS individuals were more depressed, had fewer reasons for living, and reported engaging in more current suicidal and life-threatening behavior than NoHS participants. However, gender and history of suicidality were found to interact. NoHS women reported avoiding a variety of injury-producing and health-diminishing behaviors that were common for all other groups of college students. Meanwhile, HS women endorsed fewer current reasons for living than did NoHS women, NoHS men, and NoHS men. These findings were interpreted both with regard to cultural and gender-specific expectations for the expression of self-destructive, suicidal, and life-threatening behavior. Implications for the prevention of college women's and men's suicidal behavior were also noted. 相似文献

How do communities establish shared communication systems? The Common Knowledge view assumes that symbolic conventions develop through the accumulation of common knowledge regarding communication practices among the members of a community. In contrast with this view, it is proposed that coordinated communication emerges a by‐product of local interactions among dyads. A set of multi‐agent computer simulations show that a population of “egocentric” agents can establish and maintain symbolic conventions without common knowledge. In the simulations, convergence to a single conventional system was most likely and most efficient when agents updated their behavior on the basis of local rather than global, system‐level information. The massive feedback and parallelism present in the simulations gave rise to phenomena that are often assumed to result from complex strategic processing on the part of individual agents. The implications of these findings for the development of theories of language use are discussed. 相似文献
