SOME TEMPORAL PARAMETERS OF NON-CONTINGENT REINFORCEMENT1

Instrumental and Contingent Saccharin Licking in Rats: Response Deprivation and Reinforcement1

Instrumental licking of .4% saccharin solution was increased by the contingent opportunity to lick a less-preferred saccharin solution when the contingency schedule deprived the subject of the contingent response, but not otherwise. Schedules that imposed comparable amounts of response deprivation produced comparable increases in instrumental responding. The results support the hypothesis that ...

Contingent and Non-Contingent Rewards in the Employment Relationship

Contingent capture effects in temporal order judgments.

The contingent attentional capture hypothesis proposes that visual stimuli that do not possess characteristics relevant for the current task will not capture attention, irrespective of their bottom-up saliency. Typically, contingent capture is tested in a spatial cuing paradigm, comparing manual reaction times (RTs) across different conditions. However, attention may act through several mechani...

Spatio-Temporal Parameters' Changes in Gait of Male Elderly Subjects

Objectives: The purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. Methods & Materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. A four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. Kinematic data c...

Utility of Some Fibrinolytic System Parameters for Differential Diagnosis Between Ischemic and Non-Cardiogenic Chest Pain

The aim of the study is to assess the diagnostic accuracy of some fibrinolytic parameters in the differential diagnosis between patients with unstable angina (UA) and musculoskeletal disorders (MSD). Methods. This cross-sectional study included 119 patients with chest pain (CP) and provisional diagnosis “UA”. After a full set of diagnostic procedures, authors formed 4 groups: patients with isc...
