Training Synesthetic Letter-color Associations by Reading in Color

Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods because the training is a byproduct of reading and any text can be colored.

Genome Copying Errors

2021
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their survival. Therefore, the copying errors are checked and repaired at three levels. Proofreading - DNA polymerase enzymes, for example, introduce 1 incorrect nucleotide per...

Using the novel FishSim Animation Toolchain, we present a protocol for non-invasive visual manipulation of public information in the context of mate-choice copying in sailfin mollies. FishSim Animation Toolchain provides an easy-to-use framework for the design, animation and presentation of computer-animated fish stimuli for behavioral experiments with live test fish.

DNA as a Genetic Template

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Performance depends on a sequence of processes: the person first observes letter features, converts those visual details into a motor plan, and then coordinates fine hand movements to reproduce them. Perceptual feedback during production helps guide and adjust the response. This sequence makes the task useful for examining how visual information becomes organized writing behavior.
Different error patterns provide different behavioral information. Accuracy reflects how closely the response matches the model, whereas omissions indicate that some letters or features were not produced. Reversals, spacing changes, and production time add further dimensions for analysis. Together, these measures allow researchers to distinguish aspects of the observable response rather than relying on a single score.
Repeated measurement across practice or developmental stages can show whether performance changes over time. Researchers can compare accuracy, omissions, reversals, spacing, and production time between observations. A changing pattern provides behavioral evidence about improvement or alteration in writing performance, while preserving separate indicators of what changed.
An observation begins with a person viewing a written visual model and attempting to reproduce it. The resulting response can be examined for letter accuracy, omissions, reversals, spacing, and production time. Recording these features in a consistent way supports comparisons across trials, practice periods, or developmental stages.
The task yields several complementary outcomes rather than a single measure of success. Researchers can describe how accurately letters are reproduced, which elements are omitted or reversed, how letters are spaced, and how long production takes. These observations connect visible writing behavior with visual-motor performance and its change over time.
Within behavior research, the task provides an observable response that can be measured systematically. Its value comes from linking visible features of writing, such as reversals or spacing, with the processes required to observe, plan, coordinate, and monitor a response. This supports study of learning, motor development, and written-language behavior.
