Predation Risk and Avoidance Behavior in Two Freshwater Snails.
We examined the predator avoidance behaviors of two common freshwater snails, Physella virgata and Planorbella trivolvis, to the crayfish Procambarus simulans. In response to crayfish predation, the… Expand
P300 topography of amplitude/latency correlations
SummaryThe correlational association from 19 electrode sites between peak amplitude and latency for the P3(00) event-related brain potential (ERP) for n=80 homogeneous subjects was assessed using a… Expand

An electroencephalographic (EEG) study of gifted and average ability male and female adolescents, as well as college students of both sexes, was conducted to investigate further the relative… Expand
One-trial reward learning in the snail Lymnea stagnalis.
We present evidence that the pond snail Lymnaea stagnalis is capable of aquisition and extensive retention of an appetitively reinforced feeding response after only a single training trial.… Expand

The cognitive influences of omega-3 polyunsaturated fatty acids (n-3 PUFA) remain unclear throughout the life span. Dietary n-3 PUFA appear cognitively beneficial prenatally and neuroprotective at… Expand
Enhanced right hemisphere activation in the mathematically precocious: A preliminary EEG investigation
A preliminary electroencephalographic (EEG) investigation was conducted to determine if the pattern of hemispheric activation in mathematically precocious youth differs from that of average math… Expand
Sex differences, hemispheric laterality, and associated brain activity in the intellectually gifted
Benbow (1986) proposed that enhanced development of the right cerebral hemisphere may be associated with extreme intellectual giftedness. Here we report on a series of studies conducted to evaluate… Expand

The pond snail Lymnaea stagnalis is capable of rapid acquisition of a nonaversive association between food and a novel chemostimulus. Ten to twenty pairings of the unconditioned stimulus, a… Expand
P300 hemispheric amplitude asymmetries from a visual oddball task.
The P3(00) event-related potential (ERP) was elicited in 80 normal, right-handed male subjects using a simple visual discrimination task, with electroencephalographic (EEG) activity recorded at 19… Expand
Rapid, nonaversive conditioning in a freshwater gastropod. II. Effects of temporal relationships on learning.
In this paper we report that two phenomena important in vertebrate learning, the temporal distribution of training trials and the temporal relationship between the conditioned stimulus and the… Expand
