Temporal and contextual binding in episodic memory in younger and older adults.

Episodic memory (EM) is a subsystem responsible for storing and recalling information about the basic elements of an event in a binding manner. Some approaches consider the temporal element to be one of the basic components of EM ( paradigm), while others consider that the contextual component is able in practice to better represent this cognitive ability ( paradigm). The relationship of both paradigms simultaneously with other instruments for measuring EM has not been investigated in healthy older adults.

Load effect on what-where-when memory in younger and older adults.

Episodic memory (EM) is a subsystem responsible for storing and evoking information about the "What", "Where" and "When" elements of an event in an integrated way. This capacity depends of structures with hippocampus and prefrontal cortex. The effect of aging on some capacities mediated by these areas, such as the influence of the number of objects on the coding of EM, remains unexplored.

Effect of the use of a model with peer instruction for the teaching of membrane potential and action potential.

A group of teachers from Northeast Brazil developed a model of membrane potentials and action potential and tested the hypothesis that using the peer-instruction model would provide a better performance for students in reading traditional texts and lectures. The results were obtained from 357 students from 20 different courses in 9 different undergraduate programs. All students attended two 100-min theoretical lecture and, at the end of the second lecture, were asked to answer a multiple-choice question (a pretest).

Behavioral strategies and hormonal profiles of dominant and subordinate common marmoset (Callithrix jacchus) females in wild monogamous groups.

New insights into the mating systems of common marmosets suggest that they are mainly monogamous, although polygyny and polyandry occasionally occur. Long-term monitoring of wild common marmosets has shown that some reports of polygynous groups (i.e.
