Two White Carneaux hen pigeons were exposed to a 60-sec random-interval baseline procedure. Six different exteroceptive stimuli were successively correlated, within a single session, with blocks of 10 reinforcement presentations. Following this training, a non-contingent reinforcement procedure was instated with inter-reinforcement intervals of 5, 15, 30, 60, 120, and 240 sec. Within a single session, each non-contingent frequency was correlated with one of the previously presented discriminative stimuli. After an initial increase in the rate of responding as the result of a high density of non-contingent reinforcements, the rate declined as exposure to each non-contingent frequency was prolonged. 相似文献

To examine the importance of distinctive features that are used to encode consonants (following Wickelgren’s analysis) in an immediate recall task, sequences of 5 consonants, all paired with the vowel /a/ were constructed and presented aurally for recall. The middle three items in each sequence all had either the same place of articulation (front, middle, or back of the vocal apparatus), orthe same manner of articulation (voiced, unvoiced, or nasal), or were unrelated in either place or manner (control). It was shown that, in comparison with the control sequences, consonants imbedded among others articulated similarly were recalled less accurately, suggesting that these distinctive features are important in encoding and memory maintenance. A comparison of the 3 manner and 3 place features showed that the greatest difficulty in recall occurred for the similar manner sequences (especially voiced and unvoiced, implicating manner of articulation as the critical distinctive feature in aural encoding. Some discussion is also presented of a distinction between articulation and acoustic factors in encoding processes. 相似文献

The post-treatment work adjustment of mental patients receiving rehabilitation services is extremely difficult to evaluate. A follow-up study of 223 patients referred for vocational rehabilitation to the Mental Health and Manpower project from the Fort Logan Health Center revealed percentages of patients successfully employed or in training which appear to be slightly higher than those usually reported. There were marked differences in post-rehabilitation adjustment between alcoholic and psychiatric referrals. These differences in success rates appeared to be partly a function of type of placement (i.e., direct job placement, on-the-job placement, or institutional training placement). 相似文献

Drawing on the experiences of service providers supporting live-in caregivers and migrant agricultural workers in two Canadian provinces (Ontario and Quebec), we explore how structural violence shapes the precarious conditions of female temporary foreign workers. Service providers emphasized how transnational social pressures on women to maintain employment, the captivity involved in women’s employment contracts, the limits on unionization, and women’s isolation and lack of privacy, act together to create an unbalanced relationship between the employer and female worker. In turn, this leads to precarious migration and work conditions that foster a vulnerability to violence and abuse while at the same time limiting access to and delivery of services and social support to female temporary foreign workers. Amid these restrictions, service providers focus on making a difference where they can through initiatives such as human rights education workshops, offering support, understanding Canadian regulation, and empowerment workshops. Greater Canadian national options for permanent residency status could provide a basis for adequate services to temporary foreign workers as part of their universal human rights. Temporary foreign workers contribute to Canadian society, making it encumbant upon the Canadian state to ensure the respect of their universal human rights. 相似文献
