  • The dynamic transition from an apo receptor to an active signaling complex remains largely elusive. The recent publications of TAS2R structural data have not fully elucidated this process.

  • The mechanism of activation and ligand selectivity in the TAS2R family remains opaque due to the large sequence variability of TAS2Rs and their highly varying ligand binding capacity. The study aims to address this gap by determining the structure of the active human TAS2R14 in complex with miniG-gustducin and bound to flufenamic acid (FFA).

  • There is a lack of understanding about the relationship between sweetness perception and body weight. Prior studies have investigated this relationship, but the findings are inconsistent.

    Sensory Discrimination, Intensity Perception, and Affective Judgment of Sucrose-Sweetness in the Overweight · 1982 · DOI

  • Age-related changes in response criterion and salivary sodium can affect taste thresholds. The study requires a large sample size to accurately measure taste thresholds. The research needs to control for various factors that can influence taste thresholds.

    Taste Thresholds: Quality Specific Variation with Human Aging · 1982 · DOI

  • The study did not control for potential confounding variables, such as medication use or smoking status. The sample size was limited to 71 individuals. The study did not investigate the underlying mechanisms of age-related changes in sucrose taste sensitivity.

    Sucrose Taste Thresholds: Age-related Differences · 1982 · DOI

  • Further studies are needed to investigate the underlying mechanisms of age-related changes in sucrose taste sensitivity. The study highlights the importance of considering age-related changes in taste sensitivity in food production and marketing. Future research should aim to develop dietary counseling strategies for elderly individuals with decreased sucrose taste sensitivity.

    Sucrose Taste Thresholds: Age-related Differences · 1982 · DOI

  • Future research should investigate the mechanisms underlying representation-mediated extinction. Future research should examine the applicability of representation-mediated extinction to other types of conditioned responses. Future research should explore the potential therapeutic applications of representation-mediated extinction.

    Representation-mediated extinction of conditioned flavor aversions · 1982 · DOI

  • The study identifies a gap in current research regarding the understanding of how the representation of a flavored stimulus contributes to the extinction of a conditioned aversion. The study notes that prior work has not fully explored the role of representation-mediated extinction in the extinction of conditioned flavor aversions.

    Representation-mediated extinction of conditioned flavor aversions · 1982 · DOI

  • The study relied on self-reported data. The sample size was limited to 517 undergraduates. The study did not control for all potential variables that could influence the acquisition of taste aversions.

    The acquisition of taste aversions in humans · 1981 · DOI

  • Little is known about the acquisition of taste aversions in humans. Prior studies have focused primarily on animal models. There is a need for more research on the acquisition of taste aversions in humans.

    The acquisition of taste aversions in humans · 1981 · DOI

  • There is a lack of understanding of the effects of age on the acquisition and extinction of conditioned taste aversion. Previous studies have not investigated age differences in the acquisition and extinction of conditioned taste aversion in mature male rats.

    Conditioned taste aversion as a function of age in mature male rats · 1980 · DOI

  • The paper notes that the separate presentation of elements may have effects on performance in ways other than disrupting the within-compound association, such as reducing novelty and generating differences in neophobia or latent inhibition. The paper also notes that the findings may be limited by the specific experimental design and procedures used.

    The extinction of within-compound flavor associations · 1978 · DOI

  • Future research should investigate the mechanisms underlying the extinction of within-compound associations. Further studies should examine the effects of separate presentation of elements on within-compound associations in different contexts. Research should also explore the implications of the findings for our understanding of Pavlovian conditioning and flavor aversion.

    The extinction of within-compound flavor associations · 1978 · DOI

  • The relationship between CS amount and aversion magnitude is not well understood. Prior work has reported mixed results on the effects of CS duration and amount on taste aversion learning.

    CS duration, amount, and concentration effects in conditioning taste aversions · 1976 · DOI

  • Future research could explore the ways in which children's taste is influenced by different types of literature. Future research could investigate the impact of children's literature on their developing taste.

    A question of taste · 1976 · DOI

  • The paper identifies a gap in the understanding of children's taste in literature. The paper highlights the need to explore how children's taste can be influenced by the literature they read.

    A question of taste · 1976 · DOI

  • The study only used a small sample of 18 naive female rats. The experiment was limited to a specific type of reinforcer (saccharin) and a specific type of cue (gustatory). The study did not investigate the long-term effects of saccharin reinforcement on flavor preferences.

    Immediate and delayed reinforcers for flavor preferences in rats · 1975 · DOI

  • The understanding of how saccharin reinforcement works with gustatory cues is limited. The conditions under which flavor preferences can be reinforced in rats are not well understood. The role of consummatory responding in reinforcing flavor preferences is not clear.

    Immediate and delayed reinforcers for flavor preferences in rats · 1975 · DOI

  • The lack of awareness about the environmental effects of salting roads. The lack of information on the disposition and actual effects of additives in salt on the environment.

    …Add Salt to Taste · 1972 · DOI

  • The gap in the literature is the lack of understanding of how drive level interacts with positive contrast. The study addresses the question of whether positive contrast effects can be obtained with conventional rewards.

    Positive and negative contrast in licking with shifts in sucrose concentration as a function of food deprivation · 1971 · DOI

  • Further research is needed to investigate the underlying causes of the decline in taste sensitivity. Further research is needed to develop new methods for assessing taste sensitivity. Further research is needed to investigate the effects of aging on taste sensitivity in different populations.

    Age, Sex and Taste Sensitivity · 1964 · DOI
