  • compress global dilate local intentional binding in action outcome alternations
    2019
    Co-Authors: Shu Imaizumi, Yoshihiko Tanno, Hiroshi Imamizu
    Abstract:

    Abstract Intentional binding refers to subjective temporal attraction between an action and its outcome. However, the nature of intentional binding in multiple actions remains unclear. We examined intentional binding in alternated action–outcome dyads. Participants actively or passively pressed a key, followed by a tone, and they again pressed the key; resulting in four Keypress–tone dyads in a trial. Participants reproduced the duration of alternated Keypress–tone dyads or the temporal interval between a dyad embedded in the alternations. The reproduced duration was shorter in the active than in the passive condition, suggesting the intentional binding in action–outcome alternations. In contrast, the reproduced interval between a dyad was longer in the active condition and did not correlate with the reproduced duration. These results suggest that subjective time during actions relies not only on an internal clock but also on postdictive biases that are switched based on what we recall.

  • intentional binding coincides with explicit sense of agency
    2019
    Co-Authors: Shu Imaizumi, Yoshihiko Tanno
    Abstract:

    Sense of agency, a feeling of generating actions and events by oneself, stems from action-outcome congruence. An implicit marker of sense of agency is intentional binding, which is compression of subjective temporal interval between action and outcome. We investigated relationships between intentional binding and explicit sense of agency. Participants pressed a key triggering auditory (Experiment 1) or visual outcome (Experiment 2) that occurred after variable delays. In each trial, participants rated their agency over the outcome and estimated the Keypress-outcome temporal interval. Results showed that delays decreased agency ratings and intentional binding. There was inter-individual correlation between sensitivities to outcome delay (i.e., regression slope) of agency rating and intentional binding in the auditory but not visual domain. Importantly, we found intra-individual correlations between agency rating and intentional binding on a trial-by-trial basis in both outcome modalities. These results suggest that intentional binding coincides with explicit sense of agency.

  • compress global dilate local intentional binding in action outcome alternations
    2018
    Co-Authors: Shu Imaizumi, Yoshihiko Tanno, Hiroshi Imamizu
    Abstract:

    Perceived temporal interval between voluntary action and its outcome is shorter than that between involuntary action and its outcome (i.e., intentional binding). Although the effect is robust and extensively employed as a marker of sense of agency, the nature of intentional binding in multiple actions and outcomes remains unclear. We examined intentional binding in alternated action-outcome dyads. Participants actively or passively pressed a key, followed by a tone, and they again pressed the same key immediately after the preceding tone; resulting in four Keypress-tone dyads in a trial. Participants reproduced the duration of alternated Keypress-tone dyads or the temporal interval between a dyad embedded in the alternations. The reproduced duration was shorter in the active than in the passive condition, suggesting the intentional binding in action-outcome alternations. In contrast, the reproduced interval between a dyad was longer in the active condition and did not correlate with the reproduced duration of the alternations. These results suggest that subjective time during actions may rely not only on a general internal clock; rather, it may also be modulated by postdictive biases that are flexibly switched based on what we recall.

  • is attention really biased toward the last target location in visual search the role of focal attention and stimulus response translation rules
    2019
    Co-Authors: Matthew D. Hilchey, Jay Pratt, Dominique Lamy
    Abstract:

    There is considerable confusion in the visual attention literature as to whether shifts of attention are biased against or in favor of previously attended regions. Studies requiring target localization have shown a performance cost when the target location randomly repeats instead of changes, whereas studies requiring arbitrary Keypress responses to target identities have shown a benefit. These studies differ in the amount of attention required to the target and in the stimulus-response translation rules. To evaluate the contribution of each of these factors in accounting for the mixed results, we had participants indicate whether color singletons appeared in the left versus right visual field, or in the upper versus lower visual field, by making spatially compatible Keypress responses (a between-experiment manipulation of the stimulus-response translation rules). Within each experiment, we manipulated whether a subtle discrimination of shape was necessary before localizing the target (a manipulation of focal attention). The findings revealed that the costs and benefits for repeating the target location are determined by stimulus-response translation rules, with no effect of or on attention independent of these rules. The results are accounted for by the theory of event coding, and further challenge the notion that location repetition effects reliably reflect attentional bias.

  • Is attention really biased toward the last target location in visual search? Attention, response rules, distractors, and eye movements.
    2019
    Co-Authors: Matthew D. Hilchey, Victoria M. Antinucci, Dominique Lamy, Jay Pratt
    Abstract:

    The visual search and target–target cueing literatures have reached opposite conclusions about whether a shift of attention is biased toward or away from, respectively, previously attended target locations. In this article, we aimed to figure out why. The main differences between the two experimental approaches concern (1) the stimulus–response translation rules (“what” identification Keypresses vs. “where” localization responses), (2) the amount of attention required in order to identify the target, and (3) distractor presence or absence. Experiment 1 tested the role of stimulus–response translation rules by requiring both an eye movement “where” response and a Keypress “what” response to each target, in a typical search paradigm. Eye movements showed a bias away from the vicinity of the previous target, whereas Keypresses showed a bias toward the previous target location, but only when the Keypress response repeated. Experiment 2 removed the Keypress identification requirement, to test whether reducing the amount of attention to the target would alter the eye movement bias; it did not. Experiment 3 removed the distractors, to test whether eliminating the potential for distractor location effects would alter the eye movement bias; it did, by accentuating the eye movement bias against the last target location. Collectively, the findings revealed that different stimulus–response translation rules and distractor-processing requirements are the main reasons for the discrepancy, while demonstrating that shifts of attention intrinsically tend away from prior target locations. The findings are generally consistent with episodic-retrieval and inhibited spatial-reorienting theories.

  • planning Keypress and reaching responses effects of response location and number of potential effectors
    2008
    Co-Authors: Jos J Adam, Bettine Taminiau, Natasja Van Veen, Bart H L Ament, Jons Rijcken, Kenneth Meijer, Jay Pratt
    Abstract:

    In previous work the authors argued that the potential number of effectors in the response set is crucial in discriminating (multiple-effector) Keypress from (single-effector) reaching responses. It is not clear, however, what influence the locus of responding (on vs. off the stimulus location for reaching and Keypressing, respectively) has on reaction time (RT) performance. In 3 experiments, the authors systematically manipulated response location and response type using a spatial precuing task. The results consistently showed that even though response location did influence the RTs of Keypress and reaching responses, the effect of the number of potential effectors was dominant in shaping the prototypical RT profiles of the 2 response types. These outcomes underscore the importance of the anatomical identity, in addition to response location, in response coding and corroborate the notion that distinct mechanisms dominate performance in single- and multiple-effector visuomotor tasks.

  • inhibition of return in single and dual tasks examining saccadic Keypress and pointing responses
    2008
    Co-Authors: Jay Pratt, Bas Neggers
    Abstract:

    Two experiments are reported in which inhibition of return (IOR) was examined with single-response tasks (either manual responses alone or saccadic responses alone) and dual-response tasks (simultaneous manual and saccadic responses). The first experiment—using guided limb movements that require considerable spatial information—showed more IOR for saccades than for pointing responses. In addition, saccadic IOR was reduced with concurrent pointing movements, but manual IOR was not affected by concurrent saccades. Importantly, at the time of saccade initiation, the arm movements did not start yet, indicating that the influence on saccade IOR is due to arm-movement preparation. In the second experiment, using localization Keypress responses that required only minimal spatial information, greater IOR was again found for saccadic than for manual responses, but no effect of concurrent movements was found. These findings add further support that there is a dissociation between oculomotor and skeletal-motor IOR. Moreover, the results show that the preparation manual responses tend to mediate saccadic behavior—but only when the manual responses require high levels of spatial accuracy—and that the superior colliculus is the likely neural substrate integrating IOR for eye and arm movements.

  • planning Keypress and reaching responses manipulating number of effectors and preparation interval
    2007
    Co-Authors: Jos J Adam, Bettine Taminiau, Jay Pratt
    Abstract:

    This study tested the hypothesis that separate mechanisms mediate the planning of reaching and Keypress responses. Participants performed a spatial precueing task with two preparation intervals (100 ms and 1000 ms) and three response sets: (a) pressing one of four response keys; (b) reaching with one of two hands; and (c) reaching with one hand. Reaction time results showed a pattern of precueing effects that strongly depended on the number of effectors in the response set and on the preparation interval. This outcome was interpreted as evidence that distinct mechanisms mediate the planning of multiple-effector and single-effector actions, with effector selection being relevant in the former but not in the latter. The theoretical implications of this conclusion are discussed.
