What's the difference between reinforcement and shaping?

Reinforcement


Definition:

  • (n.) See Reenforcement.

Example Sentences:

  • (9) Behavioral variables, including interreinforcement interval and drug self-administration history, appear to be important determinants of whether or not reinforcement will be demonstrated, particularly among the benzodiazepines; but the range of conditions under which behavioral and pharmacological variables interact to promote or lessen the likelihood of self-administration of these drugs remains to be determined experimentally.
  • (10) In a recent study, Orr and Lanzetta (1984) showed that the excitatory properties of fear facial expressions previously described (Lanzetta & Orr, 1981; Orr & Lanzetta, 1980) do not depend on associative mechanisms; even in the absence of reinforcement, fear faces intensify the emotional reaction to a previously conditioned stimulus and disrupt extinction of an acquired fear response.
  • (11) The reinforcement portion of the surgical drape that contained the fenestration was segmented into four identical-appearing sections, two on each side of the fenestration.
  • (12) These results indicate that auditory localization behavior of infants is influenced by reinforcement and that the extent of this effect is related to the type of reinforcement employed.
  • (13) The interresponse-time reinforcement contingencies inherent in these schedules may actually mask the effects of overall reinforcement rate; thus differences in response rate as a function of reinforcement rate when interresponse-time reinforcement is eliminated may be underestimated.
  • (14) Two experiments reported the effects of prefeeding normal and septal rats prior to their daily sessions on a differential reinforcement of low rates (DRL-20) schedule.
  • (15) Specimens of human bone from the site exhibited lower strontium levels and strontium-to-calcium ratios than deer specimens from the same site, reinforcing paleodemographic evidence that the human populations that inhabited this site included substantial amounts of meat in their diets.
  • (16) It is suggested that serotoninergic mechanisms in case of changes in activity of cholinergic processes, depress the system of positive reinforcement.
  • (17) A yeast protein, Sui3, isolated as an extragenic suppressor of his4 initiation codon mutations, exhibits extensive sequence identity with human eIF-2 beta, especially in the polylysine and zinc finger domains, thereby reinforcing the view that these elements are important for function.
  • (18) Pedestrianising areas in the city centre, reinforcing police and security.
  • (19) A visually reinforced headturn discrimination procedure was used to determine sensitivity to increments in peak F0 in synthetic speech in both bisyllabic (CVCVC) and trisyllabic (CVCVCVC) contexts.
  • (20) When reinforcement for competing behavior was withdrawn, however, rats resumed their original behavior and there were no overall savings in total responses to extinction.

Shaping


Definition:

  • (p. pr. & vb. n.) of Shape

Example Sentences:

  • (1) The predicted non-Lorentzian line shapes and widths were found to be in good agreement with experimental results, indicating that the local orientational order (called "packing" by many workers) in the bilayers of small vesicles and in multilamellar membranes is substantially the same.
  • (2) The significance of the differences in these two patterns of actin is discussed in terms of differences in the accommodative ability and static lens shape in these two animals.
  • (3) A J-shaped relationship with a dip at the middle SBP (140-149 mmHg) was recognized between treated SBP and CVD.
  • (4) After four years of existence, many evaluations were able to show the qualities of this system regarding root canal penetration, cleaning and shaping.
  • (5) In this paper we present a robust algorithm to determine automatically contours with elliptical shapes.
  • (6) Sickle and normal discocytes both showed membrane elasticity with reversion to original cell shape following release of the cell from its aspirated position at the pipette tip.
  • (7) These observations suggest that the liver secretes disk-shaped lipid bilayer particles which represent both the nascent form of high density lipoproteins and preferred substrate for lecithin-cholesterol acyltransferase.
  • (8) The heterogeneity of obesity may be demonstrated by the shape of fat distribution and the prolactin response to insulin hypoglycaemia.
  • (9) We present numerical methods for studying the relationship between the shape of the vocal tract and its acoustic output.
  • (10) The shape of the nucleus changes from ovoid to a distinctive, radially splayed lobulated structure.
  • (11) Urinalysis revealed a low pH, increased ketones and bilirubin excretion, dark yellowish change in color, the appearance of "leaflet-shaped" crystals and increased red blood cells and epithelial cells in the urinary sediment, increased water intake, decreased specific gravity and decreased sodium, potassium and chloride in the urine.
  • (12) The drop in endosome pH increased and the shape of the distribution changed when the time between FITC-dextran infusion and kidney removal was increased from 5 to 20 min.
