Reward-associated features are prioritized during attentional selection. This priority is long-lasting even when task-irrelevant (Anderson et al., 2013) suggesting that reward associations are a particularly potent attentional cue that operates through selection history (Awh et al., 2012) and is separate from typical top-down and bottom-up cues (Posner, 1980). Reward-associated features have also been shown to magnify repetition priming effects (Kristjánsson et al., 2010). We investigated whether repetition priming for rewarded and non-rewarded dimensions would be modulated by top-down knowledge of current task goals. We employed a target discrimination task consisting of two phases, an initial rewarded phase (participants learned a color-reward mapping) followed by an extinction phase (learned color-reward mapping became invalid). Consistent with Kristjánsson et al., the repetition priming effect was bigger for rewarded than non-rewarded targets, but only during the rewarded phase. The novel ...
Repetition priming refers to improvements in a behavioural response when stimuli are repeatedly presented. The improvements can be measured in terms of accuracy or reaction time, and can occur when the repeated stimuli are either identical or similar to previous stimuli. These improvements have been shown to be cumulative, so as the number of repetitions increases the responses get continually faster up to a maximum of around seven repetitions. These improvements are also found when the repeated items are changed slightly in terms of orientation, size and position. The size of the effect is also modulated by the length of time the item is presented for and the length time between the first and subsequent presentations of the repeated items. Repetition priming can occur without a person being aware of either the repeats or the improvements in his/her response, so it is generally thought to involve implicit memory processes that are dissociable from explicit memory processes. This idea has support ...
Future repetitions - estimated number of repetitions of the item in the next thirty years, and the time needed for executing repetitions in that period. This value is easily derived from A-Factor, Repetitions, Forgetting index, and the matrix of optimal factors (see: SuperMemo Algorithm). You can click on the Forgetting index field to change the forgetting index and see how that changes the estimation of future repetitions. SuperMemo roughly predicts that there will still be 1 repetition of the presented item in the next 30 years. Avg Time in Statistics makes it possible to estimate that the cost of retaining the presented item in memory until 2039 is 9 seconds on the assumption the item will not be forgotten in the meantime. Still, the probability of a memory lapse before 2039, assuming no delays, is 10% (1 repetition with the forgetting index of 10% result in 0.9 probability of correct recall). Note that Future Repetition is the estimate from before the execution of a repetition. After the ...
Building Lean Muscle Mass: Why Resting Helps BUILD UP MUSCLE Resting properly between workouts and between models is vital to building lean body mass. Between sets, you should wait enough period so that your muscles are rested plenty of to perform aswell as you do on your first heavy lifting set. Your next set of repetitions needs to be nearly as extreme as your 1st set so that the overload to each muscles involved s almost the same as the prior set 2 ingredients . For instance, lets suppose you do a group of six repetitions and right afterward are only able to execute a set of 3 repetitions. This implies you are either doing far too much weight or you havent rested correctly enough between models. Overload refers to the ability to lift a fat a degree of times again and again. Today lets say you perform six repetitions of confirmed weight and then on another set increase the weight slightly and rest for 90 seconds to 2 a few minutes. You should be in a position to do six even more repetitions ...

Humans are high-dimensional, complex systems consisting of many components that must coordinate in order to perform even the simplest of activities. Many behavioral studies, especially in the movement sciences, have advanced the notion of soft-assembly to describe how systems with many components coordinate to perform specific functions while also exhibiting the potential to re-structure and then perform other functions as task demands change. Consistent with this notion, within cognitive neuroscience it is increasingly accepted that the brain flexibly coordinates the networks needed cope with changing task demands. However, evaluation of various indices of soft-assembly has so far been absent from neurophysiological research. To begin addressing this gap, we investigated task-related changes in two distinct indices of soft-assembly using the established phenomenon of EEG repetition suppression. In a repetition priming task, we assessed evidence for changes in the correlation dimension and fractal
We examined the relationship of musculoskeletal risk factors underlying force and repetition on tissue responses in an operant rat model of repetitive reaching and pulling, and if force x repetition interactions were present, indicative of a fatigue failure process. We examined exposure-dependent changes in biochemical, morphological and sensorimotor responses occurring with repeated performance of a handle-pulling task for 12 weeks at one of four repetition and force levels: 1) low repetition with low force, 2) high repetition with low force, 3) low repetition with high force, and 4) high repetition with high force (HRHF). Rats underwent initial training for 4-6 weeks, and then performed one of the tasks for 12 weeks, 2 hours/day, 3 days/week. Reflexive grip strength and sensitivity to touch were assayed as functional outcomes. Flexor digitorum muscles and tendons, forelimb bones, and serum were assayed using ELISA for indicators of inflammation, tissue stress and repair, and bone turnover.
People often fail to respond to an auditory target if they have to respond to a visual target presented at the same time, a phenomenon known as the Colavita visual dominance effect. To date, the Colavita effect has only ever been demonstrated in detection tasks in which participants respond to pre-defined visual, auditory, or bimodal audiovisual target stimuli. Here, we tested the Colavita effect when the target was defined by a rule, namely the repetition of any event (a picture, a sound, or both) in simultaneously-presented streams of pictures and sounds. Given previous findings that people are better at detecting auditory repetitions than visual repetitions, we expected that the Colavita visual dominance effect might disappear (or even reverse). Contrary to this prediction, however, visual dominance (i.e., the typical Colavita effect) was observed, with participants still neglecting significantly more auditory events than visual events in response to bimodal targets. The visual dominance for bimodal
The production of speech and music are two human behaviors that involve complex hierarchical structures with implications for timing. Timing constraints may arise from a human proclivity to form self-organized metrical structures for perceived and produced event sequences, especially those that involve repetition. To test whether the propensity to organize events in time arises even for simple motor behaviors, we developed a novel experimental tapping paradigm investigating whether participants use the beat structure of a tapped pattern to determine the interval between repetitions. Participants listened to target patterns of 3, 4, or 5 events, occurring at one of four periodic rates, and tapped out the pattern 11 times, creating 10 inter-pattern intervals (IPIs), which participants chose freely. The ratio between mean IPI and mean inter-tap interval (ITI) was used to measure the beat-relatedness of the overall timing pattern; the closer this ratio is to an integer, the more likely the participant was

Gymstick H20 also incorporates the TRIOS technique, developed by Gymstick International. TRIOS are sets of three exercises that progressively increase in intensity by adding more fitness elements such as balance, range of motion and increased joint action. Members are free to choose the level of intensity and resistance they apply with each movement. Each section of the TRIOS is 30 seconds in length and this means that for most exercises there will only be enough time for 8 to 12 repetitions. This repetition range falls within the range that will most likely achieve muscle hypertrophy and strength. This is one of the advantages that TRIOS has over conventional barbell or muscle conditioning workouts, as these types of workouts focus on the number of repetitions to reach fatigue. ...

Considering the set main effect, differences were found in the total number of repetitions between set 1 (30.3 ± 7.4) and the other sets (set 2 = 19.0 ± 4.1, p = 0.0002; set 3 = 17.3 ± 3.2, p = 0.0004), with no differences between these two. Intervals main effect was not significant (p = 0.1844), indicating that the total number of repetitions in the three sets (3 min = 22.9 ± 4.5; 1 min = 21.1 ± 5.1; RMox = 22.7 ± 5.0) was not different among intervals. However, when the number of repetitions from the first to the last set was compared, using ANOVA for repeated measurements, significant difference was found among intervals (p = 0.0019), which was identified between the 1 min (6.0 ± 2.7) and the other intervals (3 min = 3.0 ± 1.2, p = 0.0056; RMox = 4.0 ± 2.5, p = 0.0053).. DISCUSSION. This study had the aim to compare performance measured as the maximum number of repetitions, with different intensities, different speeds of movement, and different rest intervals between sets. The ...
Heres a great tip of how you can build quality muscle mass with a simple adjustment in your weight training routine.. As you know, super slow reps increase the intensity of your exercise by increasing the demands on the muscle fibres.. It does this by lengthening the amount of time you spend in a particular exercise movement.. The next time your doing a barbell curl, instead of doing your usual repetition, try doing super slow repetitions.. I can guarantee you that you will not be able to do the same amount of repetitions as you normally would. This is a good thing because you are placing more demands on the muscle group.. Now, If you were to actually alternate your repetition speed by using super slow reps together with your usual rep speed, you can possibly add a whole new dimension to your training. You see, most people in the gym who want to build muscle, all focus on the amount of weight that is being lifted and the number of sets and reps they do. The next time your in the gym, take a ...
Our research with strength-training speed has demonstrated 50 percent better results with slower repetitions compared with faster repetitions.
Why are we prone to make mistakes in light of misleading information, even when accurate information is right there in front of us?. Demonstration #1. Before we get started on addressing this question, I would like to you to try to answer another very straightforward question: Are there more words in the English language that begin with the letter r or have r as their third letter?. The answer, as some, though likely not all, may have guessed (without reading ahead, of course!) was that there are more words that have r as the third letter. In reality, there are nearly twice as many words that have the letter r in the third position as opposed to the first position by some estimates. Most people guess that there are more words that begin with r because such words are easier to generate; however, there are apparently many more words that have r as the third letter (see Tversky and Kahneman, 1973). To name a few as examples: car, bird, warm, xerox, etc.. But why does this seem so counterintuitive? ...

The Russians call it the load volume, although sometimes they speak of the load or the volume. We talk about the tonnage and mean the same thing as load volume. The load volume, however, is not the only thing which must be considered or else the man in our sample schedule could do numerous repetitions with light weights and get the same end tonnage. The intensity must be carefully graded. Most novices want to keep increasing the poundage of their maximum training lifts and this will often ruin technique, hinder progress, cause staleness and even result in injury. The wise coach will gradually increase the volume by adding a repetition here and sticking on weight there -- thus the tyro is still progressing yet hardly notices the extra work. In your training log you should always keep an eye on the tonnage and intensity. Keep in mind that the "light" squat or dead lifts can add to tonnage without being intensive so must not fool yourself with such poundages. Label your exercises light, medium, or ...
