Predicting Self-Reported Affective Responses to Exercise: An Examination of Individual Differences
From the two models of personality, little evidence was found for personality dimensions predicting post-exercise affective responses. Limited support was also available for the two models of regional brain activity. For the models of regional brain activity, many of the results were in the …

Individual Differences in Emotional Awareness and the Lateralized Processing of Emotion
Right hemisphere dysfunction as well as an interhemispheric deficit were indicated by the behavior of early attentional (P100) and later semantic (N400, P300) components in the High Alexithymic (HA) group. Many of these effects were emotion-specific, but some were not. A P100 selective attention …

Processing Unattended Visual Information: Insights From an Analysis of Repetition Priming Using Event-Related Brain Potentials
Two unresolved issues in the attention and memory literature concern the extent and nature of the processing of unattended visual information. In an earlier study, it was found that when individuals make lexical decisions about one of two simultaneously presented, visual letter strings, a …

An Endogenous Metric for the Perception of Short Temporal Intervals
… rejection of the simplistic isomorphism between physiological change and the perception of time, which is implied by the chemical clock hypothesis, is based upon such non-linearity and not on subject inconsistency as has been the case with previous empirical investigations. The study indicates …

Effects of Environmental Temperature on Sleep and Waking in Normal Rats and Rats With Basal Forebrain Damage
Damage to the basal forebrain (preoptic area and surrounding structures) causes hyposomnia and impairs body temperature regulation. Normal sleep is sensitive to thermal stress--animals spend the most time asleep at thermoneutral temperatures, and amounts of sleep decline in the heat and in the …

Ultramorphological Study of Synaptic Activity and Efficacy Change in the Perifused Rat Hippocampal Slice
This study examined anatomical correlates of synaptic activity produced efficacy change and high levels of continuous synaptic activation which did not produce efficacy change. Long term potentiation in hippocampal CA1 was used as a model of efficacy change. After potentiating stimulation (100Hz …

Cortical Eeg Following Bilateral Lateral Hypothalamic Damage: Effects of Drugs Acting on Some Components of the Reticular Formation (Hippocampus, Animal-Model, Pharmacology)
Following large bilateral lateral hypothalamic damage (BLH) rats are somnolent (appear behaviorally asleep) and show cortical EEG of high voltage and slow waves (HVS) all the time. The failure to maintain cortical low voltage and fast EEG (LVF) as the normal rat does, may reflect disruption of some …

Influence of the Pattern of Hormone Administration on Behavioral and Biochemical Responses to Estrogens
The pattern of estrogen administration has recently been recognized as an important factor in determining the biological response to the hormone. The experiments carried out in this dissertation have investigated a particular phenomenon by which two pulses of estradiol stimulate female sexual …

Behavioral and Electromyographic Comparisons of Neuroleptic and Opiate Catalepsy in Rats
My experiments demonstrate that morphine and haloperidol produce two distinct and contrasting behavioral states, which can be thought of as exaggerated, isolated, and simplified forms of organized adaptive behavioral states functioning as components of normal motivated behavior. Haloperidol ca

The assessment of psychological vulnerability in adolescents: An alternative to genetic high-risk methodology
The present research was designed within the framework of the diathesis-stress model of psychopathology which assumes that manifest psychopathology is the result of the interaction of stress with a latent vulnerability. Previous research has relied on a genetic risk criterion, selecting as subjects …

The Relationship of Physical Activity to Physical and Psychological Well-Being
A community telephone survey of 401 Illinois adults indicates that differences in sporting behavior are most apparent when looking at type of activity (i.e. team versus individual involvement). Women, non-whites and persons from lower social classes are stratified into specific types of activities, …

Optimizing the use of information: The strategic control of the activation of responses
"Recent theories of information processing propose that visual information is processed in parallel during an early phase, and serially during a later phase. Depending on stimulus conditions, subjects respond sometimes during the parallel phase, and sometimes during the serial phase. This may …

EEG measures of subjects with idiopathic chemical sensitivity: A test of the sensitization model
This study tested the sensitization model proposed by Bell, Miller & Schwartz (1992) to study multiple chemical sensitivity (MCS). The sensitization models indicates that a traumatic event which elicits a strong response can sensitize limbic and/or mesolimbic pathways and future less intense trauma …

The mechanism of action of the anticancer effects of selenomethionine on colon cancer
Selenomethionine, an organic derivative of selenium, has been found to be the predominate selenium component of the dietary cancer chemopreventive agent selenized yeast that has been shown to decrease the incidence and mortality rate of lung, colon, and prostate cancers. Another organic selenium …

Psychophysiological responses to affective stimuli in high, moderate, and low socialized students
Psychophysiological responses (e.g. startle blink magnitude and ERPs) have demonstrated sensitivity to individual differences in humans (e.g. Patrick, Bradley, & Lang, 1993), as well as discriminating between the valence and arousal qualities of affective stimuli such as photographs depicting …

Using event-related potentials to monitor the time course of mental processing during eye fixations in reading
A new method for measuring the temporal course of processing events that take place during eye fixations in reading was tested. The method was employed to determine the earliest point in time that orthographic information is utilized during an eye fixation in normal reading. Right handed male and …
