The shuttlebox performance of goldfish was studied under standardized conditions in a variety of problems--with or without an avoidance contingency, a conditioned stimulus (CS)-termination contingency, and an escape contingency. The effects of CS-only, unconditioned stimulus (US)-only, and explicitly unpaired training were also examined. All the data could be simulated quantitatively with a ver...

Evaluative conditioning (EC) is defined as the change in the evaluation of a conditioned stimulus (CS) due to its pairing with a valenced unconditioned stimulus (US). According to propositional accounts, EC effects should be qualified by the relation between the CS and the US. Dual-process accounts suggest that relational information should qualify EC effects on explicit evaluations, whereas im...

Research has dealt with the consequences of seeking casual partners online, but has been silent about its antecedents.To address this research gap, this study tested two hypotheses.The compensation hypothesis states that people high in dating anxiety and low in physical self-esteem seek casual dates online because the features of online communication (e.g. reduced cues, anonymity, controllabili...

Clear speech has been shown to have an intelligibility advantage over casual speech in noisy and reverberant environments. This work validates spectral and time domain modifications to increase the intelligibility of casual speech in reverberant environments by compensating particular differences between the two speaking styles. To compensate spectral differences, a frequency-domain filtering a...

by relying mainly on the accessibility approach to anaphora, this article intends to analyze the types, distributions and retrieval of anaphors in two forms of spoken discourse: casual and controlled talk. for the specific purposes of the study, twenty sophomore iranian students were randomly selected to conduct the talks. the subjects were divided into two groups of casual and controlled talk....

Neuromuscular electrical stimulation (NMES) increases the excitability of corticospinal (CS) pathways by altering circuits in motor cortex (M1). How NMES affects circuits interposed between the ascending afferent volley and descending CS pathways is not known. Presently, we hypothesized that short-latency afferent inhibition (SAI) would be reduced and afferent facilitation (AF) enhanced when NM...

Classical eye-blink conditioning in mutant mice can be used to study the molecular mechanisms underlying associative learning. To measure the kinetic and frequency domain properties of conditioned (tone - periorbital shock procedure) and unconditioned eyelid responses in freely moving mice, we developed a method that allows adequate, absolute, and continuous determination of their eyelid moveme...

Five conditioned and five unconditioned response procedures for assessing hearing in mice are reviewed. The five conditioned response procedures are conditioned suppression/avoidance, go/no-go, eyeblink conditioning, avoidance conditioning, approaching the source of a sound, and GSR conditioning. Of these, the conditioned suppression/avoidance procedure is the most effective as it has the short...

The effects of lesions of the cerebellum on the acquisition and retention of aversive Pavlovian conditioned bradycardia were examined in rabbits. Lesions of the anterior cerebellar vermis severely attenuated the acquisition of simple conditioned bradycardia without disrupting baseline heart rate (HR), or unconditioned HR responses. Also, lesions of the vermis performed after the acquisition of ...
