The baseline conditions for press reports were identical to the operant conditions except the press was not followed by the tone. The instructions were identical to the operant conditions.
For tone reports there was a single baseline condition for both delayed and proximal conditions. The tone was played at a random time between 2.Intent Versus Impact: When Making a Difference Doesn’t - Miriam Barnett - TEDxTacoma
Participants were instructed to wait for the tone and afterward report the time it occurred. The different conditions were presented in blocks consisting of 40 trials each. Each delayed conditions were repeated three times see Table 1to ensure an approximately even amount of trials between the proximal conditions and the different delays in the delayed conditions.
This gave a total of 13 blocks trials. The order of blocks was randomized for each participant. Before the experiment began, participants completed 10 training trials for both delayed and proximal conditions, half of which were tone reports and half of which were press reports.
Participants were encouraged to take breaks between each block. Participants were instructed to mark trials in which they failed to comply with the instructions in any way, e. Due to an error, the time the tones were played was logged incorrect. Hence, only responses from the press conditions were analyzed. The tone conditions were repeated in a second experiment Experiment 2.
The repetition of the tone conditions in a new experiment was not a concern, as it has been shown that the binding effect depends on partially different processes for tone and press Moore and Fletcher, ; Wolpe et al. Trials in which participants reported they made an error, and trials where the letter shown at press was not similar to the letter shown one, three, or five letters earlier, were removed.
One whole block from a single participant was excluded as the participant had removed the headphones. An average of 5. Data was analyzed by mixed-effect regression models using R R Core Team and the lme4 package Bates et al. The regression models were fitted to the judgment error for all individual trials by full maximum-likelihood estimation. The full model contained the factor delay [zero delay proximal conditionone-letter delay, three-letter delay, and five-letter delay], the factor condition baseline or operantand the interaction between the factors.
Significance testing was done by removing predictors one by one from the full model, starting with the highest order interaction. Models with and without each predictor were then compared by log-likelihood ratio tests. In addition to the predictors of interest the full model included trial order and block order to control the effect of the experiment duration. Both these predictors were centered on their means so coefficients of the model reflected the average influence of these effects. To test whether the duration of the experiment or the unequal number of blocks of proximal and delayed conditions the full model included the interaction between block order, delay and condition.
The random effects structure contained the factors delay and condition and individual slopes for the effect of block order for each participant. None of the participants reported to have noticed the letters were systematically presented one, three, or five letters later when directly asked after the experiment.
The coefficient for condition has a positive sign, which confirms that a binding effect is occurring see Figure 3bottom. The group level reported times of press estimated from the model are presented in Table 2. Coefficients of the full model are presented in the Supplementary Table S1.

- The Difference Between Intention And Action
Reported occurrence of the press for operant conditions and baseline conditions, and the binding effect indicating the shift from baseline to operant condition, for all subjects. Goodness of fit was assessed by conditional goodness of fit, describing the overall fit of the model, and the marginal goodness of fit giving the variance explained by the fixed effect alone Nakagawa and Schielzeth, The significant interaction between delay and condition meant that the binding effect was different between the different delays Figure 3top.
The binding effect was weaker for one-letter delay compared to the proximal condition and five-letter delay. To test what drove the significant effect of delay, tests were conducted between all delays for both baseline and operant conditions. This showed significant differences between the zero delay condition and all other delays in both baseline conditions [0—1: The time of action in the proximal condition were reported later than all delayed conditions.
This did not differ between delays Figure 3top. Discussion of Experiment 1 The results showed differences in binding effect between delays, but only between the one-letter delay and the longest delay, and the one-letter delay and proximal conditions.
The most striking finding was that the reported times of press were earlier in all delayed conditions than in the proximal conditions. The baseline time for the intentional binding was earlier in the delayed conditions compared to the proximal condition. The first shift was the binding effect, where the reported occurrence of action was shifted from the baseline toward the tone, as reported many times before for review, see Moore and Obhi, The second shift was a shift in the baseline timing of action between proximal and delayed conditions.
It was hypothesized that there would be a gradual increase in binding effect as the delay between intention and action increased, if longer time was the underlying reason for the difference. If delayed and proximal intentions were different types of intention influencing the experience of action different ways, then a categorical difference were expected.
This result were, however, unexpected, as our hypotheses were about the binding effect, defined as the shift from baseline, not about the baselines alone.
The differences in the binding effect did not match either of the two hypothesized scenarios. There was no gradual increase in binding effect starting with proximal condition and increasing as the delay increased. Neither were there a clear categorical difference between the proximal condition and the delayed conditions in the binding effect. A gradual increase might be hinted starting at the one-letter delay and increasing as the delay increased, but the results are not conclusive.
However, if this were the case, then it would mean that our hypothesis that delay between intention and action, only applies for delayed intentions. It does not apply for proximal intentions that are immediately realized into action. Experiment 2 Materials and Methods Twelve new participants aged 20—26 years, mean: All gave written consent after being informed about the procedure of the experiment.
The experiment lasted for about 1 h. Participants received DKK for participating. The participants went through the tone conditions of the paradigm described above, consisting of three different instructions see Table 3. In the proximal condition, participants had to press the key immediately when they had the intention to act. In the delayed conditions, participants had to form the intention to press the key and delay the key-press until the same letter reappeared.
A tone Hz for ms was played ms after the key-press in both proximal and delayed conditions. In the baseline conditions, the tone was played at a random time within 2. In all conditions, participants had to report the time they heard the tone.
The length of the blocks was reduced from 40 trials per block to two blocks with 20 trials per block. This gave two blocks of proximal conditions, six blocks of delayed conditions, and two blocks of baseline conditions.
The order of the blocks was randomized for each participant. Participants completed five training trials for each condition to become familiar with the instructions.
The judgment error, i. Trials were rejected following the same criteria as in Experiment 1. An average of 2. Data was analyzed by mixed-effect regression. Models were fitted by full maximum likelihood estimation to the judgment errors using all trials. The main factor condition had five-levels containing zero-delay proximal conditionone-letter delay, three-letter delay, five-letter delay, and the baseline condition. Trial order, block order, and the interaction between delays and block order, were included in the model to test for the effect of the duration of the experiment.
Both trial order and block order were centered on their means. Individual intercepts were fitted for each participant for condition and individual slopes for block order.
Significance testing was done by model comparisons following the same procedure as Experiment 1. The differences between proximal and the one- three- and five-letter delays were investigated by planned post hoc comparison. Though the longest delay was more difficult than the baseline, there was nothing that suggested that reporting the delayed conditions were more difficult than the proximal condition.
The coefficients showed earlier judgment of the occurrence of tone for all operant conditions compared to the baseline condition, which confirms the binding effect in the tone conditions see Figure 4. The effect of experiment duration did not differ between conditions.
The group level reported times of tone estimated from the model are presented in Table 4. Coefficients of the full model are presented in the Supplementary Table S2. Top Reported times of the tone relative to the actual occurrence of tone, for baseline condition, proximal condition, and the different delays.
The dots indicate the individual time of report for each participant and the solid bars indicate the group level estimates. Bottom Group level estimated binding effect for tone in Experiment 2. Reported occurrence of the tone for operant conditions and baseline condition, and the binding effect indicating the shift from baseline to operant condition, for all subjects.
The binding effect was stronger for the three-letter and five-letter delays than in the proximal condition. The binding effect did not differ between the different delays in the delayed condition. Discussion of Experiment 2 The binding effect for tone did not follow the same pattern across delays as we found for press reports in Experiment 1. In Experiment 2, we found substantial binding effect in all operant conditions.
The binding effects were strongest for delayed intentions. This finding is consistent with the previous study showing stronger tone binding for delayed conditions Vinding et al. In the present study it was further tested whether the binding effect for delayed intentions varied across different delays between intentions and actions. No differences were found in the reports of tones between the different delays within the delayed conditions, only between proximal and delayed intentions.
The results did not support the hypothesis that gradually increases in delay would lead to a gradual increase in binding effect. General Discussion The experiments showed that the temporal delay between intention and action lead to changes in the reported occurrence of actions and their effects.
For neither the reports of action nor the reports of tone did we find support for the hypothesis that there would be a gradual increase in the binding effect. The results do support the hypothesis that there would be a categorical difference between delayed and proximally intended actions.
This difference was most notable for the tone reports, where delayed intentions were followed by a stronger binding effect compared to proximal intentions. The binding effect did not differ between delays for delayed intentions. The binding effect for action did not clearly support any of our initial hypotheses.
However, the difference in the baseline between proximal intentions and all the delayed intentions, which did not differ between delays for delayed intentions, imply a categorical difference see Figure 5. Group level reported times of press and tone. Press is marked by circle and tone is marked by triangles. Open symbols indicate baseline conditions and solid symbols indicate operant conditions. Arrows indicate the shift from the baselines to the operant conditions that define the binding effect.
The vertical dashed lines are the actual occurrence of press and tone ms apart. The binding effect did not follow the same pattern for tone and press. This is neither a new nor an uncommon finding.
This affected the binding effect for tone but not the binding effect for press. Similar disassociations in intentional binding between press and tone have been induced by TMS to pre-supplementary motor area only affecting press binding Moore et al.
The cognitive mechanism behind intentional binding and the experience of action have been proposed to be a result of integration of multiple feedback cues from different modalities that are weighted according to the certainties of the different feedback signals Moore and Fletcher, ; Synofzik et al.
In accordance with this view the present results suggest that delayed and proximal intentions affected the binding effect differently for the two different modalities.
The results show evidence for two perceptual shifts: The first shift was the binding effect between action and effect i. The occurrence of both action and tone were reported earlier in the delayed conditions compared to the proximal conditions. This could mean that the baseline shift in the times of action for delayed intentions drove the earlier occurrence of the tone for delayed intentions in the tone conditions.
The earlier reported occurrence of the tone is a joint effect of the earlier reported time of action. Both are shifted to an earlier time together as a pair. Several authors have proposed that delayed intentions involve prospective predictions or representations established before action is initiated, occurring outside the processes in immediate relation to action execution, that functions as global parameters for action selection Pacherie, ; Hommel, ; Synofzik et al. Though longer lasting intentions often also is referring to abstract intentions beyond simple motor intentions, our results could be interpreted as a similar effect of delayed intentions for specific actions.
Intention-Action Link and Selection Fluency: Similarly, errors in task performance may lead to a feeling of dysfluency during the task, without any explicit awareness of an error, and without the ability to explicitly report the error. Importantly, such on-line experience strongly influences the sense of agency, as shown by recent priming studies. Thus, Wenke and colleagues showed that the sense of agency could be modulated by using subliminal priming to affect the fluency of action selection processes Wenke et al.
Interestingly, this procedure enabled a manipulation of the subjective sense of agency, without manipulating the predictability of action outcomes. In this experiment, participants pressed left or right keys in response to left- or right-pointing arrow targets.
Prior to the target, subliminal left or right arrow primes were presented, unbeknownst to the subject. Prime arrow directions were either identical compatible condition or opposite incompatible condition to the subsequent target Figure 1B.
Responding to the target caused the appearance of a color after a jittered delay. The color patch can thus be considered as the action outcome. Unlike previous studies, therefore, the primes did not predict action effects, nor could any specific color be predicted on the basis of the action chosen.
Participants rated how much control they experienced over the different colors at the end of each block Wenke et al. Analyses of reaction times RTs showed that compatible primes facilitated responding whereas incompatible primes interfered with response selection. More importantly, priming also modulated the sense of agency over action effects: Thus subliminal priming made action selection processes more or less fluent, and this modulation of fluency affected the sense of agency over action outcomes 1.
These results have several important cognitive implications. First, they suggest that the sense of agency depends strongly on processes of action selection that necessarily occur before action itself. Second, strong sense of agency may be associated with fluent, uncontested action selection. In contrast, conflict between alternative possible actions, such as that caused by incompatible subliminal priming, may reduce the feeling of control over action outcomes.
Third, this prospective contribution of action selection processes to sense of agency is distinct from predicting the outcomes of action, since action outcomes were equally un- predictable for compatible and incompatible primes. That is, these primes did not prime effects of action as in previous studies e. Therefore, participants could not retrospectively base their control judgements on match between primes and effects alone. Rather, their stronger experience of control when primes were compatible could only be explained by the fluency of action selection—i.
Finally, participants did not consciously perceive the subliminal primes. Instead, action priming itself presumably directly influenced the subjective sense of agency. Pacherie Pacherie, ; see also Synofzik et al. However, it is also possible that participants might have estimated agency based on implicit monitoring of their own performance, such as their RTs.
Since RTs are lower on compatibly primed trials Dehaene et al. On this second view, agency would depend on retrospective monitoring of action execution performance Marti et al. To distinguish between these two accounts of sense of agency, we used an experimental procedure that dissociated fluency of action selection from performance monitoring Chambon and Haggard, Specifically, we increased the interval between mask and target to take advantage of a Negative Compatibility Effect NCE in priming.
Longer mask-target latencies increase RTs following compatible primes, relative to incompatible primes Schlaghecken et al. By combining this factor with Wenke et al. Specifically, if sense of agency depends on selection fluency, it should be greater when actions are compatibly fluent condition versus incompatibly dysfluent condition primed, irrespective of whether priming benefits faster RTs or impairs slower RTs performance. Alternatively, if sense of agency depends only on performance monitoring, it should be stronger for rapid versus slower responding, irrespective of whether priming is compatible or incompatible with the action executed.
Crucially, reversing the normal relationship between prime-target compatibility and RTs did not alter subjective sense of agency. Thus, in compatible NCE trials, participants experienced stronger control despite slower response times and higher error rates, compared to incompatible NCE trials Chambon and Haggard, ; see also Stenner et al. These results suggest that the feeling of control normally experienced by subjects on compatible trials does not depend on retrospectively monitoring performance, thereby strengthening the evidence for a prospective contribution of action selection fluency to sense of agency.
In both Wenke et al. Indeed, the contingency between action and color effect was similar for compatibly-primed and incompatibly-primed trials. Importantly, the prospective sense of control identified in these experiments is therefore an illusion of control, since it is not based on differences in the actual statistical relation between action and effect.
Although illusory, this prospective sense of control may nevertheless be a convenient proxy for actual control, because agents often just know what to do and what will happen next in most everyday life situations. In that sense, fluent action selection is generally a good advance predictor of actual statistical control over the external environment Haggard and Chambon, ; Chambon et al.
Prospective agency might thus reflect a learned experiential metacognition: As suggested above, internal signals of premotor fluency might not produce a strong conscious experience with distinctive content, but might influence the experience of surrounding events. In that sense, signals relating to the fluency of action selection would not be perceived for what they really are, but mis- attributed to the processes of actually controlling the action.
Such a misattribution may foster the subject not to adjust her behavior accordingly. Indeed, it has been shown that behavioral adjustment does not only depend on the presence or absence of an error, but also on its cause e. Thus, if participants misattribute dysfluency to lack of control on the selected action, and misattribute fluency to the process of actually controlling the action, then they should adjust their behavior less in the dysfluent, than in the fluent, condition—despite the fact that control is equally illusory in both conditions.
Future work is required to test this assumption directly. Neural Substrates of Prospective Fluency-Based Agency Taken together, these findings suggest that neural activity in action preparation circuits prospectively informs agency, independent of outcome predictability, and actual performance. Tracking dysfluency in action selection networks Miele et al. Recently, we adapted the prospective agency paradigm for functional neuroimaging Chambon et al.
Specifically, we studied whether the angular gyrus AGa parietal brain region which has been shown to compute retrospective agency by monitoring mismatches between actions and subsequent outcomes Farrer et al. Behavioral results replicated those of Wenke and colleagues. Again, participants experienced greater control over action effects when the action was compatibly versus incompatibly primed Chambon et al.
More importantly, this prospective contribution of action-selection processes to sense of agency was accounted for by exchange of signals between specific frontal action selection areas and the parietal cortex. First, we found that activity in the AG was sensitive to mismatches, but not matches, between prime arrow and actual response to the target arrow.
Moreover, this activity due to the prime-target mismatch predicted the magnitude of subsequent sense of agency: Importantly, this neural coding of non-agency occurred at the time of action selection only, as in Wenke et al. Second, connectivity analyses psycho-physiological interaction revealed that activity in the AG signaling non-agency in incompatible trials was negatively correlated with activity in the dorso-lateral prefrontal area DLPFC; Figure 2A. Previous studies of willed action also noticed the same frontoparietal correlation, namely, that increased activity in DLPFC was associated with decreased activity in the AG Frith et al.
Our results are directly analogous: Thus, DLPFC deactivation would signal dysfluency in the selection of willed action, as a consequence of prime-target incompatibility. Decreased DLPFC activity due to incompatible primes would in turn result in a concomitant increase in AG activity and a subjective loss of control.
Overall, this suggests that AG may monitor signals relating to fluency or dysfluency of action selection emanating from DLFPC and use them to pre construct an experience of agency. Importantly, under this interpretation, this monitoring of fluency signals by AG would occur prior to actions and their sensory consequences.
This prospective contribution of AG to sense of agency can thus be distinguished from other functions such as action outcome monitoring. Interestingly, Farrer et al. In Farrer et al. The different localization found in these two studies could thus reflect a subdivision within the inferior parietal cortex, with more dorsal AG being involved in detecting mismatch between intention and action, independent of action consequences Chambon et al.
A Sense of agency is accounted for by exchange of signals across a prefrontal-parietal network: The right chart shows a negative modulation of AG activity as a function of the level of experienced control from low to high; adapted from Chambon et al. B TMS-induced disruption of left AG at the time of action selection abolishes the compatibility effect on sense of agency right chart.
Monitoring of fluency signals by AG might provide the subject with an on-line, subjective marker of volition, prior to action itself.
As such, this finding sketches an important qualification of recent post-hoc determinist views of action control Ackerman et al. In its strongest form, determinist views suggest that human behavior is unconsciously determined by subtle changes in the stimulus environment. On this view, individuals are not even aware of how their behavior is shaped and transformed, although they can retrospectively integrate general information about past actions and environmental cues to make inferences and narrative explanations about their own behavior Wegner, In this respect, the ability to monitor fluency signals generated during action selection in AG might be an important part of what makes our action intentional, and thus a key component of the experience of agency—defined as the feeling that we are intentionally making things happen by our own choices and actions.
First, the evidence was indirect, because of the correlational nature of fMRI. Secondly, it was not possible to pinpoint the precise time at which AG is involved in the prospective coding of agency owing to the relatively poor temporal resolution of fMRI.
As we saw, the issue of timing is important for understanding where the sense of agency is computed within the intention-action-effect chain.
We recently addressed these two limitations by combining single-pulse transcranial magnetic stimulation TMS with subliminal priming of action selection and judgements of control over action effects.
On two distinct experiments we assessed the effects of TMS over left AG on action selection processing, by linking TMS to either i the presentation of the arrow target; ii to action execution; or iii to the presentation of the action effect color patch.
We made specific predictions based on our previous fMRI findings. Because AG activation correlated with sense of agency only on incompatible trials, we assumed that this area monitored signals relating to selection fluency generated by DLPFC Chambon et al.
In this case, applying TMS over AG should prevent this region from monitoring any signals from DLPFC, and hence reduce the tendency for incompatibility primes to influence judgements of control. Consistent with these predictions, we found that TMS over left AG abolished the compatibility effect i. This suggests that TMS-induced disruption of AG did not interfere with action selection processing itself, but rather interfered with a circuit that monitors selection fluency to pre-construct the experience of control.
Previously it is has been suggested that the AG is involved in the retrospective construction of sense of agency by monitoring the consistency between predicted and actual sensory consequences of movements David et al. When these predictions are violated sense of agency is reduced, and AG activity is increased.
The Difference Between Intention And Action | AccelaWork
Results from our TMS study do not disagree with this view of AG function, but point to an additional role: Note the prospective and retrospective mechanisms have some general features in common. We suggest that monitoring and checking is a very general function of the AG during instrumental action. Initial action intentions, such as those caused by subliminal primes in the series of studies described above, could be checked for compatibility with the action subsequently performed.
Not only would this provide an estimate of agency without the need to wait until sensory feedback becomes available but, as we have suggested Chambon et al. For example, the sense of agency in patients with schizophrenia is characterised by excessive reliance on re-afferent sensory information generated by their actions, presumably due to poor, or unreliable, action selection processing Voss et al. Prospective signals—such as fluency signals—may indeed provide an important counterweight to re-afferent information, and hence may protect against xenopathic experiences e.
At the same time, excessive reliance on these prospective signals may produce the opposite delusion of omnipotence, in which the mere decision to act is incorrectly assumed to produce successful action outcomes. This latter illusion appears to be common in historical despots but is interestingly absent in depressed people Alloy and Abramson, A robust and reliable sense of agency may thus require a balanced—and probably context-dependent—mixture of both prospective and retrospective components.
