Age differences in tracking characters during narrative comprehension

Understanding a narrative situation depends on keeping track of multiple characters that enter and exit dynamically as the plot unfolds. We investigated age differences in this process during narrative comprehension. In Experiment 1, we used a probe recognition paradigm to examine the effect of age on the accessibility of a previous character when another character was subsequently introduced. In Experiment 2, reading time was measured to examine age differences in the encoding of a new character after another had already been introduced. Our findings show that older readers have particular difficulty both in accessing the initial character after a new character is introduced and in thoroughly encoding a new character while other characters inhabit the discourse world. We attribute these differences to age differences in working memory that make it difficult to access a backgrounded character when a new character is in focus and to distinctively encode a new character when maintenance of another character is already consuming attentional resources.     

Revising what readers know: Updating text representations during narrative comprehension

Reading comprehension involves not just encoding information into memory, but also updating and revising what is already known or believed. For example, as narrative plots unfold, readers often must revise the expectations they have constructed from earlier portions of text to successfully comprehend later events. Evidence suggests that such revision is by no means guaranteed. In three experiments, we examined conditions that influence readers' revision of trait-based models for story characters. Trait models are particularly relevant for examining such revision because they demonstrate resistance to change. We specifically assessed whether task instructions and content-driven refutations of earlier information would enhance the likelihood of revision. In Experiment 1, instructions to carefully consider the appropriateness of story outcomes generally facilitated revision. In Experiment 2, we removed those instructions; revision occurred only when refutations included sufficient explanation to suggest that updating was necessary. Experiment 3 further supported the influence of instructions on readers' propensities to revise. These results are informative with respect to the mechanisms that guide readers' moment-by-moment comprehension of unfolding narratives.     

Emotion simulation during language comprehension

We report a novel finding on the relation of emotion and language. Covert manipulation of emotional facial posture interacts with sentence valence when measuring the amount of time to judge valence (Experiment 1) and sensibility (Experiment 2) of the sentence. In each case, an emotion-sentence compatibility effect is found: Judgment times are faster when facial posture and sentence valence match than when they mismatch. We interpret the finding using a simulation account; that is, emotional systems contribute to language comprehension much as they do in social interaction. Because the effect was not observed on a lexical decision task using emotion-laden words (Experiment 3), we suggest that the emotion simulation affects comprehension processes beyond initial lexical access.     

Character movement and the representation of space during narrative comprehension

Traditional research on situation models has examined the accessibility of locations and objects during narrative experiences. These studies have described a ubiquitous gradient effect: Spatial locations and objects in reader focus are more accessible than locations farther from this focus, with accessibility decreasing as a function of distance. How might readers’ expectations about character movement, beyond information about spatial locations, additionally affect this accessibility gradient? In two experiments, we investigated whether reader expectations for character movement impact the accessibility of spatial information from memory. In Experiment 1, participants read stories that described characters moving in either a unidirectional or a random pattern through a learned environment. In Experiment 2, characters moved forward in a unidirectional way or backtracked through previously explored rooms. The results suggest that reader expectations for character movement can influence the accessibility of spatial information. Such expectations play a critical role in processes of narrative comprehension.     

Predictability of locomotion: Effects on updating of spatial situation models during narrative comprehension

We investigated how the updating of spatial situation models during narrative comprehension depends on the interaction of cognitive abilities and text characteristics. Participants with low verbal and visuospatial abilities and participants with high abilities read narratives in which the protagonist's motions in a fictitious building were either highly predictable or very hard to predict. In Experiment 1, high-ability readers updated spatial situation models only if the protagonist's motions were hard to predict, whereas low-ability readers did so only if the motions were highly predictable. In Experiment 2, facilitated integrative spatial processing compensated for the low-ability participants' resource limitations. As a result, both ability groups updated spatial situation models with hard-to-predict protagonist motions. These results highlight the interactions of cognitive abilities and text characteristics in spatial situation model updating.     

Causal coherence and the availability of locations and objects during narrative comprehension

The aim of this study was to examine whether locations of objects are encoded and available to the reader at different points in a narrative, depending on their causal relevance. Participants in five experiments read narratives in which the spatial relation between an object and its location either did or did not provide a causal explanation for a later critical event. Object and location target words were presented to the participants immediately before or after the critical event. Speeded recognition response times to target words demonstrated that both locations and objects were reactivated, but only after they became causally relevant. The results suggest that the causal structure of a text can influence the availability of spatial information and that at least some spatial relations are encoded during reading and are available to the reader when they are needed to build coherence.     

Assessing the automaticity of moral processing: efficient coding of moral information during narrative comprehension

A long-standing theoretical debate concerns the involvement of principled reasoning versus relatively automatic intuitive-emotional processing in moral cognition. To address this, we investigated whether the mental models formed during story comprehension contain a moral dimension and whether this process is affected by cognitive load. A total of 72 participants read stories about fictional characters in a range of moral situations, such as a husband being tempted to commit adultery. Each story concluded with a "moral" or "immoral" target sentence. Consistent with a framework of efficient extraction of moral information, participants took significantly longer to read immoral than moral target sentences. Moreover, the magnitude of this effect was not compromised by cognitive load. Our findings provide evidence of efficient coding of moral dimensions during narrative comprehension and demonstrate that this process does not require cognitively intense forms of principled reasoning.

Time course of action representations evoked during sentence comprehension

The nature of hand-action representations evoked during language comprehension was investigated using a variant of the visual–world paradigm in which eye fixations were monitored while subjects viewed a screen displaying four hand postures and listened to sentences describing an actor using or lifting a manipulable object. Displayed postures were related to either a functional (using) or volumetric (lifting) interaction with an object that matched or did not match the object mentioned in the sentence. Subjects were instructed to select the hand posture that matched the action described in the sentence. Even before the manipulable object was mentioned in the sentence, some sentence contexts allowed subjects to infer the object's identity and the type of action performed with it and eye fixations immediately favored the corresponding hand posture. This effect was assumed to be the result of ongoing motor or perceptual imagery in which the action described in the sentence was mentally simulated. In addition, the hand posture related to the manipulable object mentioned in a sentence, but not related to the described action (e.g., a writing posture in the context of a sentence that describes lifting, but not using, a pencil), was favored over other hand postures not related to the object. This effect was attributed to motor resonance arising from conceptual processing of the manipulable object, without regard to the remainder of the sentence context.     

Imaginal action: towards a Jungian conception of enactment,and an extraverted counterpart to active imagination

This theoretical paper considers the fashion in which Jung's psychology radically challenges modern assumptions concerning the nature of subjectivity. With an eye for the clinical implications of Jung's late work, the author introduces the idea of imaginal action. In order to explain what is meant by this, the paper begins by exploring how Jung's thinking demonstrates an underlying bias towards introversion. It is argued that while Jung's interest in synchronicity ultimately resulted in his developing a worldview that might address the introverted biases of his psychology, the clinical implications of this shift have not been sufficiently clarified. With reference to some short examples from experience, the author outlines a conception of relational synchronicity wherein the intrapsychic emerges non‐projectively within the interpersonal field itself. Comparing and contrasting these occurrences to the more introverted practice of active imagination, it is claimed that such a notion is implicit in Jung's work and is needed as a corrective to his emphasis on interiority. The author suggests that imaginal action might be conceived as a distinctly Jungian approach to the psychoanalytic notion of enactment. It is also shown how the idea outlined might find further support from recent developments in the field of transpersonal psychology.     

Altering comprehension: The effect of biasing titles on text comprehension

Titles can alter the comprehension of a text by affecting the selection of information from a text and the organization of this information in memory. Text comprehension is assumed to involve an organizational process that results in the formation of a text base, an ordered list of semantic units—propositions. The text base can be used as a retrieval scheme to reconstruct the text. Procedures for assigning propositions as more relevant to some themes as compared to other themes are developed and applied to texts. Texts with biasing titles were used in an experiment to demonstrate that immediate free recall is biased toward the theme emphasized in the title. The comprehension process which is guided by the text’s thematical information is described.     

Time in action contexts: learning when an action effect occurs

Action effects do not occur randomly in time but follow our actions at specific delays. The ideomotor principle (IMP) is widely used to explain how the relation between actions and contingently following effects is acquired and numerous studies demonstrate robust action-effect learning. Yet, little is known about the acquisition of temporal delays of action effects. Here, we demonstrate that participants learn that action effects occur at specific delays. Participants responded slower to action effects that occurred earlier than usual. In addition, participants often prematurely responded before the effect when it occurred later than expected. Thus, in contrast to biases of time perception in action contexts (e.g., Haggard, Trends Cogn Sci 9:290–295, 2005; Stetson et al., Neuron 51:651–659, 2006), participants learn and exploit temporal regularities between actions and effects for behavioral control.     

Simulating murder: the aversion to harmful action

Diverse lines of evidence point to a basic human aversion to physically harming others. First, we demonstrate that unwillingness to endorse harm in a moral dilemma is predicted by individual differences in aversive reactivity, as indexed by peripheral vasoconstriction. Next, we tested the specific factors that elicit the aversive response to harm. Participants performed actions such as discharging a fake gun into the face of the experimenter, fully informed that the actions were pretend and harmless. These simulated harmful actions increased peripheral vasoconstriction significantly more than did witnessing pretend harmful actions or to performing metabolically matched nonharmful actions. This suggests that the aversion to harmful actions extends beyond empathic concern for victim harm. Together, these studies demonstrate a link between the body and moral decision-making processes.     

How valence affects language processing: Negativity bias and mood congruence in narrative comprehension

The present research examined how positive and negative moods affect readers’ understanding of positive and negative story endings. It demonstrated how negativity bias and mood congruence emerge during narrative comprehension. Participants were induced to experience either a positive or a negative mood and then read stories that could have either a positive or a negative ending. In Experiment 1, participants took longer to integrate negative endings than positive endings, independent of their mood. In Experiment 2, participants judged as more surprising those endings that did not match their mood. The present results illustrate that ending valence has strong influence on moment-by-moment reading, but that readers’ moods influence expectations for story outcomes once readers reflect on a complete representation of the story.     

Authorship effects in the prediction of handwriting strokes: Evidence for action simulation during action perception

Does the action system contribute to action perception? Recent evidence suggests that actions are simulated while being observed. Given that the planning and simulating system are the same only when one observes one's own actions, it might be easier to predict the future outcomes of actions when one has carried them out oneself earlier on. In order to test this hypothesis, three experiments were conducted in which participants observed parts of earlier self- and other-produced trajectories and judged whether another stroke would follow or not. When the trajectories were produced without constraints, participants accomplished this task only for self-produced trajectories. When the trajectories were produced under narrow constraints, the predictions were equally accurate for self- and for other-generated trajectories. These results support the action simulation assumption. The more the actions that one observes resemble the way one would carry them out oneself, the more accurate the simulation.
