Recognition is used as one cue among others in judgment and decision making.

Three experiments with paired comparisons were conducted to test the non-compensatory character of the recognition heuristic (D. G. Goldstein & G. Gigerenzer, 2002) in judgment and decision making. Recognition and knowledge about the recognized alternative were manipulated. In Experiment 1, participants were presented pairs of animal names where the task was to select the animal with the larger population. In Experiment 2, participants chose the safer 1 out of 2 airlines, and 3 knowledge cues were varied simultaneously. Recognition effects were partly compensated by task-relevant knowledge. The compensatory effects were additive. Decisions were slower when recognition and knowledge were incongruent. In Experiment 3, compensatory effects of knowledge and recognition were found for the city-size task which had originally been used to demonstrate the non-compensatory character of the recognition heuristic. These results suggest that recognition information is not used in an all-or-none fashion but is integrated with other types of knowledge in judgment and decision making.

Counterpropagating dipole-mode vector soliton.

We experimentally observed a counterpropagating dipole-mode vector soliton in a photorefractive SBN:60Ce crystal. We investigated the transient formation dynamics and show that the formation process differs significantly from the copropagating geometry. The experimental results are compared with fully anisotropic numerical simulations and show good qualitative agreement.

2p Photoionization of atomic Ni: a comparison with Ni metal and NiO photoionization.

The photoabsorption spectrum of the 2p-3d resonances and the 2p photoelectron spectrum of atomic Ni were investigated both experimentally and theoretically. The analysis of the spectra takes into account that at the evaporation temperature of the metal at about 1800 K the fine structure states 3d(8) 4s(2) 3F and 3d(9) 4s 3D of both configurations 3d(8) 4s(2) and 3d(9) 4s are populated. The population of these two configurations offers the unique possibility for a comparison with the corresponding spectra in the condensed phase (Ni metal and NiO) where current configuration interaction calculations use the mixture of the configurations (3d,4s)(10). By using our theoretical description of the 2p photoionization new insight into these condensed phase spectra is found.
