Studying Food Reward and Motivation in Humans
Published on: March 19, 2014
Summary
Ring doves demonstrated faster switching between food keys when signals for food were present. However, these same food signals maintained pecking on a non-reinforced key when only one option was available.
Area of Science:
- Behavioral science
- Animal cognition
Background:
- Understanding how animals respond to predictive cues is crucial in behavioral science.
- Investigating the role of learned associations in decision-making processes.
Purpose of the Study:
- To examine how predictive food signals influence key-switching behavior in ring doves.
- To determine if the presence of food cues affects the extinction of a previously reinforced response.
Main Methods:
- Ring doves were trained to peck one of two keys for food reinforcement.
- Key reinforcement was subsequently extinguished while predictive food signals were manipulated (present or absent).
- Switching behavior to the alternative key and persistence on the extinguished key were recorded.
Main Results:
- Doves switched to the alternative key significantly faster when food predictive signals were present during extinction.
- In a single-key condition, the presence of food signals maintained pecking at the extinguished key.
- This suggests that predictive cues can both facilitate and inhibit response modification depending on the context.
Conclusions:
- Predictive food signals play a complex role in regulating instrumental behavior in ring doves.
- The findings highlight the influence of learned associations and contextual cues on behavioral flexibility.
- Further research into the cognitive mechanisms underlying cue-controlled behavior is warranted.

01:31Confirmation Biases
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
01:32Types of Signaling Molecules
In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...
01:15Amplifying Signals via Second Messengers
Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
01:26Signal Transduction: Overview
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

01:30Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
