There is a growing body of research on matching- and non-matching-to-sample (MTS, NMTS) relations with rats using olfactory stimuli; however, the specific characteristics of this relational control are unclear. In the current study we examine MTS and NMTS in rats with an automated olfactometer using a successive (go, no-go) procedure. Ten rats were...
The effects of chronic adolescent fluoxetine (FLX, Prozac®) exposure on adult cognition are largely unknown. We used a serial multiple choice (SMC) task to characterize the effects of adolescent FLX exposure on rat serial pattern learning in adulthood. Male rats were exposed to either 1.0, 2.0, or 4.0 mg/kg/day FLX for five consecutive days each we...
Equivalence class formation has been difficult to demonstrate in nonhumans, but one method that has been successful is a simple discrimination procedure in which contingencies associated with two sets of arbitrary discriminative stimuli are repeatedly reversed. Pigeons and sea lions shift responding after encountering the newly-reversed contingency...
The neural, behavioral, and cognitive processes that convert experiences into neural and cognitive representations of experiences in sensation, perception, conditioning, memory, anticipation, problem solving, language, and related cognitive systems.
Two methodologies that have been successful in producing emergent symmetry in some nonhuman species include multiple exemplar training (sea lions) and successive conditional discrimination training of both arbitrary and key identity relations (pigeons). Two experiments were conducted to examine these procedures in rats using olfactory stimuli. In E...
Chunking has traditionally referred to cognitive processes that recode multiple separate stimulus events into groups in memory. Chunking has also been referred to as cognitive “recoding,” “grouping,” “sorting,” or “parsing” (e.g., Bower & Springston, 1970; Bower & Winzenz, 1969; Capaldi, Nawrocki, Miller, & Verry, 1986; Fountain & Annau, 1984; Prib...
