too many students’ congresses, are they necessary and useful?

When two is too many: Collaborative encoding impairs memory.

Humans routinely encode and retrieve experiences in interactive, collaborative contexts. Yet much of what we know about human memory comes from research on individuals working in isolation. Some recent research has examined collaboration during retrieval, but not much is known about how collaboration during encoding affects memory. We examined this issue. Participants created episodes by elabor...

Two hats too many

We view ourselves as scientists as very intelligent, extremely hard-working, and highly creative, though perhaps more competitive than we care to admit. But no one seems to recognize the high incidence of a serious medical problem among investigators — 'multiple personality disorder'. Of course I say this with tongue planted firmly in cheek, but it's not too far off the mark when we consider ou...

Analyzing Preference Rankings when There Are Too Many Alternatives

Consumer preferences can be measured by rankings of alternatives. When there are too many alternatives, this consumer task becomes complex. One option is to have consumers rank only a subset of the available alternatives. This has an impact on subsequent statistical analysis, as now a large amount of ties is observed. We propose a simple methodology to perform proper statistical analysis in thi...

Gluttonous predators: how to estimate prey size when there are too many prey.

Prey size is an important factor in food consumption. In studies of feeding ecology, prey items are usually measured individually using calipers or ocular micrometers. Among amphibians and reptiles, there are species that feed on large numbers of small prey items (e.g. ants, termites). This high intake makes it difficult to estimate prey size consumed by these animals. We addressed this problem...
