Behavioral Effects Of Tyrosine During Sustained Wakefulness, D. L. Wiegmann, D. F. Neri, R. R. Stanny, S. A. Shappell, A. H. Mccardie, D. L. Mckay

Publications

The fatigue and cognitive performance deficits associated with sleep loss and stress, like that experienced during sustained flight operations and nighttime flying, have motivated the search for effective nonpharmacological countermeasures. The behavioral effects of the potential countermeasure tyrosine, an amino-acid precursor to dopamine and norepinephrine, were examined during an episode of continuous nighttime work involving one night's sleep loss. Volunteers performed nine iterations of a battery of cognitive and subjective tasks for approximately 13 h, beginning at 1930 and ending at 0820 the following morning. Subjects remained awake throughout the day on which the experiment began and were awake for …

The Pavlov-Yerkes Connection: What Was Its Origin?, Randall D. Wight

Articles

Historians of psychology traditionally acknowledge Robert Mearns Yerkes as responsible for introducing the work of Russian physiologist Ivan Pavlov to American psychologists. The introduction occurred in a 1909 Psychological Bulletin paper coauthored with Harvard graduate student, Sergius Morgulls. Yet how Yerkes, who did not read Russian and who never personally used Pavlov's conditioning paradigm, came to know and appreciate Pavlov's endeavors is unclear. This paper examines how Yerkes became acquainted with salivary conditioning studies and suggests a reason why the 1909 paper was actually written.

Differential Reinforcement Of Other Behavior And Response Suppression: The Effects Of The Response-Reinforcement Interval, Thomas S. Rieg, Nelson F. Smith, Stuart Vyse

Psychology Faculty Publications

Three experiments were conducted comparing the effects of the relationship between the response-reinforcement interval and the reinforcement-reinforcement interval in a differential reinforcement of other behavior (DRO) contingency. The experiments followed an acquisition, treatment, and reacquisition sequence where rats were trained to press a lever for food, were exposed to response elimination contingencies (DRO and extinction), and finally tested for the effectiveness of their respective treatment conditions. Experiment 1 shows that the longer the response-reinforcement interval the more effective the suppressive effects of DRO. Experiment 2 shows that it is the relationship of the response-reinforcement interval to the reinforcement-reinforcement interval that …

An Investigation Of The Exclusion Of Students With Disabilities In National Data Collection Programs, Kevin S. Mcgrew, Martha L. Thurlow, Amy N. Spiegel

Department of Educational Psychology: Faculty Publications

This investigation examined the extent to which students with disabilities are involved in a select sample of national data collection programs that are playing a pivotal role in the measurement-driven educational reform movement. Nine data collection programs that are receiving significant attention in current educational reform initiatives were reviewed. The results suggest that approxi-mately 40% to 50% of school-age students with disabilities are excluded from some of the most prom-inent national educational data collection programs. In contrast, students with disabilities are included to a greater degree in noneducational data collection programs that do not require partici-pation in direct assessment activities. …

Community Adjustment Of Young Adults With Mental Retardation: A Developmental Perspective, Richard F. Ittenbach, Sheryl A. Larson, Amy N. Spiegel, Brian H. Abery, Robert W. Prouty

Department of Educational Psychology: Faculty Publications

The community adjustment of young adults with mental retardation remains a crucial issue for all human service providers. No longer does adjustment imply simply the physical integration of persons with disabilities into community settings. Rather, it refers to the adjustment and integration of the whole person into community life. Whether one describes community adjustment as a process, an outcome, a philosophy, or a multidimensional concept (Bachrach, 1981), community adjustment has become synonymous with the term quality-of-life, a quality that depends in large part on one’s happiness and success in socially sanctioned, age-appropriate tasks.

Memory Biases In Left Versus Right Implied Motion, Andrea R. Halpern, Michael H. Kelly

Faculty Journal Articles

People remember moving objects as having moved farther along in their path of motion than is actually the case; this is known as representational momentum (RM). Some authors have argued that RM is an internalization of environmental properties such as physical momentum and gravity. Five experiments demonstrated that a similar memory bias could not have been learned from the environment. For right-handed Ss, objects apparently moving to the right engendered a larger memory bias in the direction of motion than did those moving to the left. This effect, clearly not derived from real-world lateral asymmetries, was relatively insensitive to changes …

The Relationship Between Quantity Of Possessions Transported And Homesickness In Migrants, Rosalynn M. Morrow

Theses : Honours

The study addresses the relationship between the quantity of possessions transported by migrants from their country of origin and reported levels of homesickness. Eighty-nine subjects from the United Kingdom and Eire participated in the study, which was limited to those migrants who have been resident in Australia for less than 5 years (M=2.53). The sample was non random (purposive and accidental), consisting of 51 males and 38 females, and the mean age of the participants on arrival in Australia was 33 years. Participants completed a 32 item, Likert scale, questionnaire which incorporated items from the Fisher (1989) Dundee Relocation Inventory …

Does Religion Teach Empathy And Helpfulness? The Role Of Fundamentalism And Target Of Need In The Religion-Helping Relation, Lynne Marie Jackson

Theses and Dissertations (Comprehensive)

The empathy-altruism hypothesis predicts that when social expectation for helping is low, empathy will facilitate, and distress will attenuate, helping (Batson, 1991). Based on this prediction, this study explored the relations among religious fundamentalism, emotional reactions of empathy and distress, and helping behaviour, for differing targets of need. One hundred thirty-three introductory psychology students (38 male, 95 female), of varying levels of religious fundamentalism, read a letter ostensibly written by a person hoping to attend university during the coming academic year. The letter indicated that the author had concerns about coping with the demands of university studies. The potential student …

A Comparison Of Metamemory Judgements And Forgetting Rates For Item And Associative Recognition For Normal And Closed-Head Injured Populations, Kathy Bharrath Singh

Theses and Dissertations (Comprehensive)

Metamemory, in particular memory monitoring during a memory task, was investigated in a closed—head injured (CHI) population and a normal (control) population. Prediction ratings were used to determine memory monitoring at time of encoding, and postdiction ratings were used to determine memory monitoring at time of retrieval. Item and associative information for concrete and abstract words were tested using a forced—choice recognition test procedure. Forgetting rates for these two types of information (item and associative) were examined by analyzing immediate and final recognition memory performance. Results indicated that the CHI group had a lower overall level of recognition performance, however …
