Resurgence of goal-directed actions and habits.

This study investigated how goal-directed and habitual behaviors recover after extinction within the context of the resurgence effect, a form of relapse induced by the removal or worsening of alternative reinforcement. Rats were trained to press a target lever with one reinforcer (O1) for either minimal (4) or extended (16) sessions. An extinction test after the completion of O1 devaluation confirmed that minimal and extended training formed goal-directed and habitual behaviors, respectively. Then, pressing an alternative lever was reinforced with a second reinforcer (O2) while the target response was placed on extinction. When O2 was discontinued, the minimally trained target response resurged with goal-directed status as in the extinction test. However, the extinguished habitual behavior in the extensively trained rats did not recover as a habit but instead with goal-directed status, possibly due to the context specificity of habits or the introduction of a new response-reinforcer contingency. The critical finding that reinforcer devaluation consistently led to less resurgence regardless of the amount of acquisition training provides a clinical implication that coupling differential-reinforcement-of-alternative-behavior (DRA) treatments with the devaluation of the associated reinforcer of problematic behavior could effectively diminish its recurrence.

Contribution of dorsal versus ventral hippocampus to the hierarchical modulation of goal-directed actions in rats.

Adaptive behaviour often necessitates that animals learn about events in a manner that is specific to a particular context or environment. These hierarchical organisations allow the animal to decide which action is the most appropriate when faced with ambiguous or conflicting possibilities. This study examined the role of hippocampus in enabling animals to use the context to guide action selection. We used a hierarchical instrumental outcome devaluation task in which male rats learn that the context provides information about the unique action-outcome relations that are in effect. We first confirmed that rats encode and use hierarchical context-(action-outcome) relations. We then show that chemogenetic inhibition of ventral hippocampus impairs both the encoding and retrieval of these associations, while inhibition of dorsal hippocampus impairs only the retrieval. Importantly, neither dorsal nor ventral hippocampus was required for goal-directed behaviour per se as these impairments only emerged when rats were forced to use the context to identify the current action-outcome relationships. These findings are discussed with respect to the role of the hippocampus and its broader circuitry in the contextual modulation of goal-directed behaviour and the importance of hierarchical associations in flexible behaviour.

Reversal learning in those with early psychosis features contingency-dependent changes in loss response and learning

ABSTRACT Introduction People with psychotic disorders commonly feature broad decision-making impairments that impact their functional outcomes. Specific associative/reinforcement learning problems have been demonstrated in persistent psychosis. But these phenotypes may differ in early psychosis, suggesting that aspects of cognition decline over time. Methods The present proof-of-concept study examined goal-directed action and reversal learning in controls and those with early psychosis. Results Equivalent performance was observed between groups during outcome-specific devaluation, and reversal learning at an 80:20 contingency (reward probability for high:low targets). But when the low target reward probability was increased (80:40) those with early psychosis altered their response to loss, whereas controls did not. Computational modelling confirmed that in early psychosis there was a change in punishment learning that increased the chance of staying with the same stimulus after a loss, multiple trials into the future. In early psychosis, the magnitude of this response was greatest in those with higher IQ and lower clinical severity scores. Conclusions We show preliminary evidence that those with early psychosis present with a phenotype that includes altered responding to loss and hyper-adaptability in response to outcome changes. This may reflect a compensatory response to overcome the milieu of corticostriatal changes associated with psychotic disorders.

Towards a methodology for translation activity: an activity theory approach

ABSTRACT The question of “How translation is done” is crucial in the field of translation studies as it serves as the foundation for both teaching and criticism. To address this question, one must theoretically explain the methodology behind translation activities, including how translators select methods, strategies, and techniques to achieve meaningful translations. Despite the existence of various cross-disciplinary paradigms in translation studies, a consensus has not yet been reached on this issue. According to Activity Theorists, a socio-cultural activity is realized through goal-directed actions that are ultimately carried out by conditioned operations. Based on this perspective, we propose an explanatory framework for understanding the methodology of translation activity. This framework may also be useful for revising and evaluating the output of automatic translation operations conducted by AI language models.

Reducing binge eating through behavioral-focused versus emotion-focused implementation intentions in patients with binge eating disorder or bulimia nervosa: An experimental approach

Binge eating disorder (BED) and bulimia nervosa (BN) are characterized by recurrent binge eating, episodes of consuming large amounts of food in a discrete period of time associated with a loss of control. Implementation intentions are explicit if-then plans that engender goal-directed action, and rely less on cognitive control than standard treatment options. In a sample with BED and BN, we compared two implementation intention conditions to a control condition. In the behavior-focused condition, implementation intentions targeted binge eating behaviors. In the emotion-focused condition, implementation intentions targeted negative affect preceding binge eating. In the control condition, only goal intentions were set. Each condition comprised three sessions. Participants kept food diaries for four weeks. Compared to the control condition both implementation intention conditions showed significant and large reductions of binge eating that persisted for six months. Effects did not differ between the behavior-focused and emotion-focused implementation intention conditions. These results demonstrate that three sessions on implementation intention formation can lead to long-term reductions in binge eating in patients with BED or BN. Learning how to form implementation intentions seems a recommendable addition to the current standard treatment. Future research could investigate the added value of fully personalized implementation intentions. Clinical trial registration numberNL52600.068.15.

Antagonism of D2 receptors via raclopride ameliorates amphetamine-induced associative learning deficits in male mice

Dopamine levels in the dorsomedial striatum (DMS) are highly dynamic and are thought to underly the encoding of action-outcome associations. Although it is known that amphetamine disrupts the learning that is required for goal-directed action, the role of D1 and D2 receptors in this process has not been established. In this study, we examined the role of D1 and D2 receptor antagonists on learning in response to amphetamine. We used the outcome-specific devaluation task to examine goal-directed action in male C57BL6/J mice treated systemically with either a D1 antagonist (SCH-23990; 0.01 mg/kg) or a D2 antagonist (raclopride; 0.5 mg/kg) and then administered amphetamine (1 mg/kg). The mice were injected repeatedly throughout the instrumental training phase of the task to assess the impact on the learning of action-outcomes, and the subsequent choice test assessing performance of goal-directed action was conducted drug free. Effects of chronic drug administration on locomotor behaviour was assessed before and after the choice test. Treatment during learning with either amphetamine, or the D1 or D2 antagonists, impaired the subsequent performance of goal-directed action. The amphetamine-induced impairment in goal-directed action was reversed in mice treated with raclopride, but not when treated with SCH-23990. By contrast, amphetamine-induced hyperactivity was reversed in mice treated with SCH-23990, but not in mice treated with raclopride. Taken together, these data support the role of a balance of dopamine receptor signalling after amphetamine treatment. While overall D1 receptor availability is necessary to promote learning, in a state of elevated dopamine, modifying D2 receptor function can ameliorate learning deficits.

Environmental factors contributing to negative symptoms in youth at clinical high risk for psychosis and outpatients with schizophrenia.

A bioecosystem theory was recently proposed positing that negative symptoms of schizophrenia (SZ) are influenced by environmental factors. These environmental processes reflect sources of resource deprivation that manifest across multiple systems that impact individuals directly through microsystems and indirectly through the exosystem and macrosystem. As an initial test of this theory, the current study examined whether self-reported environmental resource deprivation was associated with anhedonia, avolition, and asociality. Two samples were collected: (1) outpatients with schizophrenia or schizoaffective disorder (SZ: n = 38) and matched psychiatrically heathy controls (CN: n = 31); (2) youth at clinical high risk for psychosis (CHR: n = 34) and matched CN (n = 30). Measures of negative symptoms and environmental factors influencing the frequency of recreational, goal-directed, and social activities were collected. Negative symptoms were associated with environmental deprivation factors in the microsystem (number of social and activity settings) and exosystem (economy, mass media, politics/laws, neighborhood crime). These associations did not appear due to depression and were greater among those with SZ than CHR. These findings provide preliminary support for the bioecosystem theory and highlight an under-recognized role for environmental factors underlying negative symptoms across phases of psychotic illness. Environmental systems-focused treatment approaches may offer a novel means of treating negative symptoms, which could be promising when coupled with person-level pharmacological and psychosocial treatments.

Dopamine receptors of the rodent fastigial nucleus support skilled reaching for goal-directed action

The dopaminergic (DA) system regulates both motor function, and learning and memory. The cerebellum supports motor control and the acquisition of procedural memories, including goal-directed behavior, and is subjected to DA control. Its fastigial nucleus (FN) controls and interprets body motion through space. The expression of dopamine receptors has been reported in the deep cerebellar nuclei of mice. However, the presence of dopamine D1-like (D1R) and D2-like (D2R) receptors in the rat FN has not yet been verified. In this study, we first confirmed that DA receptors are expressed in the FN of adult rats and then targeted these receptors to explore to what extent the FN modulates goal-directed behavior. Immunohistochemical assessment revealed expression of both D1R and D2R receptors in the FN, whereby the medial lateral FN exhibited higher receptor expression compared to the other FN subfields. Bilateral treatment of the FN with a D1R antagonist, prior to a goal-directed pellet-reaching task, significantly impaired task acquisition and decreased task engagement. D2R antagonism only reduced late performance post-acquisition. Once task acquisition had occurred, D1R antagonism had no effect on successful reaching, although it significantly decreased reaching speed, task engagement, and promoted errors. Motor coordination and ambulation were, however, unaffected as neither D1R nor D2R antagonism altered rotarod latencies or distance and velocity in an open field. Taken together, these results not only reveal a novel role for the FN in goal-directed skilled reaching, but also show that D1R expressed in FN regulate this process by modulating motivation for action.

Dogs Rely On Visual Cues Rather Than On Effector-Specific Movement Representations to Predict Human Action Targets.

The ability to predict others' actions is one of the main pillars of social cognition. We investigated the processes underlying this ability by pitting motor representations of the observed movements against visual familiarity. In two pre-registered eye-tracking experiments, we measured the gaze arrival times of 16 dogs (Canis familiaris) who observed videos of a human or a conspecific executing the same goal-directed actions. On the first trial, when the human agent performed human-typical movements outside dogs' specific motor repertoire, dogs' gaze arrived at the target object anticipatorily (i.e., before the human touched the target object). When the agent was a conspecific, dogs' gaze arrived to the target object reactively (i.e., upon or after touch). When the human agent performed unusual movements more closely related to the dogs' motor possibilities (e.g., crawling instead of walking), dogs' gaze arrival times were intermediate between the other two conditions. In a replication experiment, with slightly different stimuli, dogs' looks to the target object were neither significantly predictive nor reactive, irrespective of the agent. However, when including looks at the target object that were not preceded by looks to the agents, on average dogs looked anticipatorily and sooner at the human agent's action target than at the conspecific's. Looking times and pupil size analyses suggest that the dogs' attention was captured more by the dog agent. These results suggest that visual familiarity with the observed action and saliency of the agent had a stronger influence on the dogs' looking behaviour than effector-specific movement representations in anticipating action targets.

Freedom of choice boosts midfrontal theta power during affective feedback processing of goal-directed actions

Sense of agency, the feeling of being in control of one’s actions and their effects, is particularly relevant during goal-directed actions. During feedback learning, action effects provide information about the best course of action to reinforce positive and prevent negative outcomes. However, it is unclear whether agency experience selectively affects the processing of negative or positive feedback during the performance of goal-directed actions. As an important marker of feedback processing, we examined agency-related changes in midfrontal oscillatory activity in response to performance feedback using electroencephalography. Thirty-three participants completed a reinforcement learning task during which they received positive (monetary gain) or negative (monetary loss) feedback following item choices made either by themselves (free-choice) or by the computer (forced-choice). Independent of choice context, midfrontal theta activity was more enhanced for negative than positive feedback. In addition, free, compared to forced choices increased midfrontal theta power for both gain and loss feedback. These results indicate that freedom of choice in a motivationally salient learning task leads to a general enhancement in the processing of affective action outcomes. Our findings contribute to an understanding of the neuronal mechanisms underlying agency-related changes during action regulation and indicate midfrontal theta activity as a neurophysiological marker important for the monitoring of affective action outcomes, irrespective of feedback valence.

A Rational Account of Cognitive Control Development in Childhood

Cognitive control is defined as a set of processes required for the organization of goal-directed thoughts and actions. It is linked to success throughout life including health, wealth, and social capital. How to support the development of cognitive control is therefore an intensively discussed topic. Progress in understanding how this critical life skill can be optimally scaffolded in long-lasting ways has been disappointing. I argue that this effort has been hampered by the predominant perspective that cognitive control is a competence or ability, the development of which is driven by predetermined maturational sequences. I propose that this traditional view needs to be overhauled in light of a growing body of evidence suggesting that cognitive control allocation is a both highly dynamic and rational process subject to cost–benefit analyses from early in development. I discuss the ramifications of shifting our perspective on cognitive control mechanisms in relation to how we design interventions. I close by spelling out new avenues for scientific inquiry.

Maintaining eye fixation relieves pressure of cognitive action control

Cognitive control enables humans to behave guided by their current goals and intentions. Cognitive control in one task generally suffers when humans try to engage in another task on top. However, we discovered an additional task that supports conflict resolution. In two experiments, participants performed a spatial cognitive control task. For different blocks of trials, they either received no instruction regarding eye movements or were asked to maintain the eyes fixated on a stimulus. The additional eye fixation task did not reduce task performance, but selectively ameliorated the adverse effects of cognitive conflicts on reaction times (Experiment 1). Likewise, in urgent situations, the additional task reduced performance impairments due to stimulus-driven processing overpowering cognitive control (Experiment 2). These findings suggest that maintaining eye fixation locks attentional resources that would otherwise induce spatial cognitive conflicts. This reveals an attentional disinhibition that boosts goal-directed action by relieving pressure from cognitive control.

Immp2l knockdown in male mice increases stimulus-driven instrumental behaviour but does not alter goal-directed learning or neuron density in cortico-striatal circuits in a model of Tourette syndrome and autism spectrum disorder

Cortico-striatal neurocircuits mediate goal-directed and habitual actions which are necessary for adaptive behaviour. It has recently been proposed that some of the core symptoms of autism spectrum disorder (ASD) and Gilles de la Tourette syndrome (GTS), such as tics and other repetitive behaviours, may emerge because of imbalances in these neurocircuits. We have recently developed a model of ASD and GTS by knocking down Immp2l, a mitochondrial gene frequently associated with these disorders. The current study sought to determine whether Immp2l knockdown (KD) in male mice alters flexible, goal- or cue- driven behaviour using procedures specifically designed to examine response-outcome and stimulus-response associations, which underlie goal-directed and habitual behaviour, respectively. Whether Immp2l KD alters neuron density in cortico-striatal neurocircuits known to regulate these behaviours was also examined. Immp2l KD mice and wild type-like mice (WT) were trained on Pavlovian and instrumental learning procedures where auditory cues predicted food delivery and lever-press responses earned a food outcome. It was demonstrated that goal-directed learning was not changed for Immp2l KD mice compared to WT mice, as lever-press responses were sensitive to changes in the value of the food outcome, and to contingency reversal and degradation. There was also no difference in the capacity of KD mice to form habitual behaviours compared to WT mice following extending training of the instrumental action. However, Immp2l KD mice were more responsive to auditory stimuli paired with food as indicated by a non-specific increase in lever response rates during Pavlovian-to-instrumental transfer. Finally, there were no alterations to neuron density in striatum or any prefrontal cortex or limbic brain structures examined. Thus, the current study suggests that Immp2l is not necessary for learned maladaptive goal or stimulus driven behaviours in ASD or GTS, but that it may contribute to increased capacity for external stimuli to drive behaviour. Alterations to stimulus-driven behaviour could potentially influence the expression of tics and repetitive behaviours, suggesting that genetic alterations to Immp2l may contribute to these core symptoms in ASD and GTS. Given that this is the first application of this battery of instrumental learning procedures to a mouse model of ASD or GTS, it is an important initial step in determining the contribution of known risk-genes to goal-directed versus habitual behaviours, which should be more broadly applied to other rodent models of ASD and GTS in the future.

Task-dependent alteration of beta-band intermuscular coherence is associated with ipsilateral corticospinal tract excitability.

Beta-band (15-30 Hz) synchronization between the EMG signals of active limb muscles can serve as a non-invasive assay of corticospinal tract integrity. Tasks engaging a single limb often primarily utilize one corticospinal pathway, although bilateral neural circuits can participate in goal-directed actions involving multi-muscle coordination and utilization of feedback. Suboptimal utilization of such circuits after CNS injury can result in unintended mirror movements and activation of pathological synergies. Accordingly, it is important to understand how the actions of one limb (e.g., a less-affected limb after strokes) influence the opposite corticospinal pathway for the rehabilitation target. Certain unimanual actions decrease the excitability of the "unengaged" corticospinal tract, presumably to prevent mirror movement, but there is no direct way to predict the extent to which this will occur. In this study, we tested the hypothesis that task-dependent changes in beta-band drives to muscles of one hand will inversely correlate with changes in the opposite corticospinal tract excitability. Ten participants completed spring pinching tasks known to induce differential 15-30 Hz drive to muscles. During compressions, transcranial magnetic stimulation single pulses to the ipsilateral M1 were delivered to generate motor-evoked potentials in the unengaged hand. The task-induced changes in ipsilateral corticospinal excitability were inversely correlated with associated changes in EMG-EMG coherence of the task hand. These results demonstrate a novel connection between intermuscular coherence and the excitability of the "unengaged" corticospinal tract and provide a springboard for further mechanistic studies of unimanual tasks of varying difficulty and their effects on neural pathways relevant to rehabilitation.

VIP interneurons in sensory cortex encode sensory and action signals but not direct reward signals

Vasoactive intestinal peptide (VIP) interneurons in sensory cortex modulate sensory responses based on global exploratory behavior and arousal state, but their function during non-exploratory, goal-directed behavior is not well understood. In particular, whether VIP cells are activated by sensory cues, reward-seeking actions, or directly by reinforcement is unclear. We trained mice on a Go/NoGo whisker touch detection task that included a delay period and other features designed to separate sensory-evoked, action-related, and reward-related neural activity. Mice had to lick in response to a whisker stimulus to receive a variable-sized reward. Using two-photon calcium imaging, we measured ΔF/F responses of L2/3 VIP neurons in whisker somatosensory cortex (S1) during behavior. In both expert and novice mice, VIP cells were strongly activated by whisker stimuli and goal-directed actions (licking), but not by reinforcement. VIP cells showed somatotopic whisker tuning that was spatially organized relative to anatomical columns in S1, unlike lick-related signals which were spatially widespread. In expert mice, lick-related VIP responses were suppressed, not enhanced, when a reward was delivered, and the amount of suppression increased with reward size. This reward-related suppression was not seen in novice mice, where reward delivery was not yoked to licking. These results indicate that besides arousal and global state variables, VIP cells are activated by local sensory features and goal-directed actions, but not directly by reinforcement. Instead, our results are consistent with a role for VIP cells in encoding the expectation of reward associated with motor actions.

Continuous action with a neurobiologically inspired computational approach reveals the dynamics of selection history.

Everyday perception-action interaction often requires selection of a single goal from multiple possibilities. According to a recent framework of attentional control, object selection is guided not only by the well-established factors of perceptual salience and current goals but also by selection history. Yet, underlying mechanisms linking selection history and visually-guided actions are poorly understood. To examine such interplay and disentangle the impact of target and distractor history on action selection, we employed a priming-of-popout (PoP) paradigm combined with continuous tracking of reaching movements and computational modeling. Participants reached an odd-colored target among homogeneous distractors while we systematically manipulated the sequence of target and distractor colors from one trial to the next. We observed that current reach movements were significantly influenced by the interaction between attraction by the prior target feature and repulsion by the prior distractor feature. With principal component regression, we found that inhibition led by prior distractors influenced reach target selection earlier than facilitation led by the prior target. In parallel, our newly developed computational model validated that current reach target selection can be explained best by the mechanism postulating the preceded impact of previous distractors followed by a previous target. Such converging empirical and computational evidence suggests that the prior selection history triggers a dynamic interplay between target facilitation and distractor inhibition to guide goal-directed action successfully. This, in turn, highlights the necessity of an explicitly integrated approach to determine how visual attentional selection links with adaptive actions in a complex environment.

The Representation of Third-Party Helping Interactions in Infancy

Despite numerous findings on the sophisticated inferences that human infants draw from observing third-party helping interactions, currently there is no theoretical account of how infants come to understand such events in the first place. After reviewing the available evidence in infants, we describe an account of how human adults understand helping actions. According to this mature concept, helping is a second-order, goal-directed action aiming to increase the utility of another agent (the Helpee) via reducing the cost, or increasing the reward, of the Helpee's own goal-directed action. We then identify the cognitive prerequisites for conceiving helping in this way and ask whether these are available to infants in the interpretation of helping interactions. In contrast to the mature concept, we offer two simpler alternatives that may underlie the early understanding of helping actions: ( a) helping as enabling, which requires second-order goal attribution but no utility calculus, and ( b) helping as joint action, which requires efficiency (i.e., utility) evaluation without demanding second-order goal attribution. We evaluate the evidence supporting these accounts, derive unique predictions from them, and describe what developmental pathway toward the mature concept they envisage. We conclude the article by outlining further open questions that the developmental literature on the interpretation of helping interactions has not yet addressed.

How attention factors into executive function in preschool children.

Executive Function consists of self-regulation processes which underlie our ability to plan, coordinate, and complete goal-directed actions in our daily lives. While attention is widely considered to be central to the emergence and development of executive function during early childhood, it is not clear if it is integral or separable from other executive function processes. Previous studies have not addressed this question satisfactorily because executive function and attention are multidimensional constructs, but they are often studied without differentiating the specific processes that are tested. Moreover, some studies consist of only one task per process, making it difficult to ascertain if the pattern of results is attributable to different processes or more simply to task variance. The main aim of this study was to more fully investigate how attention factored into the underlying structure of executive function in preschool children. Preschool children (n = 137) completed a battery of tasks which included executive function (i.e., response inhibition, working memory) and attentional control (i.e., sustained attention, selective attention) processes; there were two tasks per process. Confirmatory factor analyses (CFA) were conducted to test which of three models fit the data best: (1) a unitary one-factor model with attention loading onto the same factor as other executive function processes, (2) a two-factor model with attention loading onto a separate factor than other executive function processes, or (3) a three-factor model with attention, response inhibition, and working memory as separate factors. Fit indices and model comparisons indicated that the two-factor model fit the data best, suggesting that attentional control and executive function were related, but separable. Although this study is not the first to advocate for a two-factor model during the preschool years, it is the first to suggest that the two factors are attentional control and executive function, not working memory and response inhibition. One important implication of these findings is that a complete assessment of executive function during the preschool years necessitates measuring not only response inhibition and working memory, but attentional control as well.

Flexible Changes in Attentional Focus and Task Rules Rely on A Shared Set of Frontoparietal Oscillatory Dynamics.

Flexible changes in behavior can involve changes in the processing of external information (i.e., shifts in attention between different stimuli) or internal information (i.e., shifts in task rules stored in memory). However, it is unclear if different types of flexible change rely on separate, domain-specific neural processes or on a domain-general system, which enables flexible actions independent of the type of change needed. In the current study, participants performed a task switching procedure while we measured neural oscillations via EEG. Importantly, we independently manipulated the need to switch attention between 2 types of stimuli, as well as the need to switch between two sets of stimuli-response rules stored in memory. Both attentional and rule switches significantly increased error rates and RTs. On a neural level, both types of changes were associated with a widespread decrease in alpha power, predominantly over the parietal cortex. Attentional switches and rule switches showed a subadditive interaction effect on both participants' performance as well as on their alpha power reactivity. This indicates that implementing both changes at the same time was more efficient than implementing each individual change separately. Independent of the presence or absence of either attentional or rule switches, higher frontal theta power and lower parietal/posterior alpha power predicted faster responses on correct trials. Our study suggests that flexible behavior relies on domain-general frontal and parietal oscillatory dynamics, which enable efficient implementation of goal-directed actions independent of which aspects of the task change.

Goal-directed action anticipation and prediction error processing in children with autism spectrum disorders: An eye-movement study

BackgroundDifferences in predictive ability have been proposed as a possible explanation for the core symptoms of autism spectrum disorder (ASD). This study aimed to investigate potential differences in prior knowledge acquisition and application for goal-directed anticipation in children with ASD. MethodThe study included 22 children with ASD and 19 typically developing (TD) children between the ages of 5–10 years. Two eye-tracking phases were used to examine the formation of goal-directed action anticipations and the processing of action prediction errors. In the action anticipation formation phase, participants were asked to observe goal-directed actions repeatedly to examine prior knowledge acquisition about agent-goal association. In the action anticipation violation phase, the goals of actions were changed to examine the application of previously acquired knowledge. ResultsChildren with ASD required more trials to form goal-directed anticipations than TD children. Furthermore, prior knowledge acquisition was characterized by variability and instability in children with ASD. During the action anticipation violation phase, children with ASD exhibited lower preference for the action goal determined by prior knowledge in uncertain situations. This atypical processing of prior knowledge was significantly correlated with the severity of ASD symptoms. ConclusionsOur findings support the Bayesian perception theory and predictive coding theory, suggesting that children with ASD may experience difficulties in both the acquisition and application of prior knowledge in anticipation. These findings have implications for developing interventions to improve goal-directed anticipation and reduce social and communication difficulties in individuals with ASD.
