Cardiac Changes During An Attention-Demanding Task In Mentally Retarded Adults, James M. Granfield
Cardiac Changes During An Attention-Demanding Task In Mentally Retarded Adults, James M. Granfield
Student Work
The relationship between physiological response patterns and intellectual deficiencies was investigated by examining heart rate changes during a sustained attention-demanding task with institutionalized mentally retarded adults classified into three different I.Q. levels. The task consisted of simple motor responses made to a visual display within which was "hidden" the stimulus cue of Santa Claus. The findings indicated that changes in the within-trial heart rate response were significantly different between groups. Consistent with previous research on retarded adolescents, the retarded adults in the present study were characterized by a significant increase in heart rate variability upon stimulus onset. However, the high …
The Effects Of Extrinsic Rewards On Intrinsic Motivation: Reinforcement Theory Or Cognitive Evaluation Theory, Jack S. Leon
The Effects Of Extrinsic Rewards On Intrinsic Motivation: Reinforcement Theory Or Cognitive Evaluation Theory, Jack S. Leon
Student Work
Intrinsically motivated behaviors are those for which there is no apparent reward except the activity itself. Such rewards are mediated within the individual. Rather than bringing about external rewards, intrinsically motivated behaviors bring about internal states that the individual finds rewarding (Deci, 1975a).
A Developmental Study Of Target Attribution, Dotti Cohen
A Developmental Study Of Target Attribution, Dotti Cohen
Student Work
The purpose of this study was to determine the existence of target attribution, and its interaction with other variables. Subjects were obtained from grades one, seven, and college freshmen; thirty of each age group were used. The subjects consisted of an equal number of males and females, who scored as internal or external on a locus of control measure. Each individual was asked to assume the role of actor in each of four videotapes, and to rate the degree of responsibility they felt for the action on each scene. The subjects were also asked to rate the actor and the …
Effects Of Task Size And Group Size On Observers' Job Enrichment Perceptions, Yau-De Wang
Effects Of Task Size And Group Size On Observers' Job Enrichment Perceptions, Yau-De Wang
Student Work
Stemming from different theoretical disciplines, investigators of undermanned behavior settings and job enrichment have focused on examining human performance and motivation by manipulating essential tasks and available personnel. Although these two disciplines have centered their concerns on different types of organizations, research results from undermanning and job enrichment studies have tended to coincide with each other. However, an important question common to both areas concerns the reasons why the manipulation of the number of tasks and the number of personnel in a work setting should change group members' performance and motivation. Greenberg (1979) has recently offered an explanation which may …
A Behavioral Study Of Maternal-Infant Interaction With Focus On Infant Attachment And Infant Cognition, Bruce Mcnickle
A Behavioral Study Of Maternal-Infant Interaction With Focus On Infant Attachment And Infant Cognition, Bruce Mcnickle
Student Work
This study examined the interactions between 15 maternal-infant dyads using an operant learning format with special emphasis on the relationship of infant attachment to maternal behaviors, specifically the securityinsecurity dimension of infant attachment. Observations of maternal-infant interactions were made each month from infant ages 9 months to 12 months. Maternal and infant behaviors were coded and each category was scored for frequency and duration of behavior with an Esterline-Angus Event Recorder. Maternal ratios of responding and latency in responding to infant behaviors were calculated from the Esterline-Angus charts. Infants were administered several cognition tests and an attachment test, while mothers …
