Motivational Control of Second-Order Conditioning.

Journal of Experimental Psychology: Animal Behavior Processes, 2005
Two experiments examined the motivational specificity of the associations that support 2nd-order conditioning. In the 1st phase of each experiment rats were exposed to 2 visual conditioned stimuli (CSs) paired with either a saline or food pellet unconditioned stimulus (US) prior to exposure to 2nd-order conditioning using 2 auditory CSs, 1 paired with ...

Some determinants of second-order conditioning

Learning & Behavior, 2010
In a Pavlovian conditioning situation, an initially neutral stimulus may be made excitatory by nonreinforced presentations in compound with an established conditioned excitor [i.e., second-order conditioning (SOC)]. The established excitor may be either a punctate cue or the training context.

On second order conditions for quasiconvexity

Mathematical Programming, 1980
The paper presents a sufficient condition for quasiconvexity in terms of Hessian, hereby extending an earlier result by Katzner in 1970, and (by a slight modification of the assumptions) a necessary and sufficient condition for quasiconvexity.

On second-order conditions in unconstrained optimization

Mathematical Programming, 2007
The main aim of this paper is to generalize early obtained sufficient second-order optimality conditions which were introduced in terms of the Peano type and the Dini type of directional derivatives for the class of \(C^{1,1}\) functions or for the class of stable functions.

Second Order Optimality Conditions Based on Parabolic Second Order Tangent Sets

SIAM Journal on Optimization, 1999
Summary: We discuss second order optimality conditions in optimization problems subject to abstract constraints. Our analysis is based on various concepts of second order tangent sets and parametric duality. We introduce a condition, called second order regularity, under which there is no gap between the corresponding second order necessary and second ...

On First- and Second-Order Conditions for Error Bounds

SIAM Journal on Optimization, 2004
Summary: We establish first-order and second-order sufficient conditions ensuring that a proper lower semicontinuous function \(f\) on a Banach space \(X\) has an error bound. We also consider similar problems with constraint, namely, that \(f\) is replaced by its restriction to a subset of \(X\).
