Memory-Load Interference in Syntactic Processing

Participants remembered a short set of words while reading syntactically complex sentences (object-extracted clefts) and syntactically simpler sentences (subject-extracted clefts) in a memory-load study. The study also manipulated whether the words in the set and the words in the sentence were of matched or unmatched types (common nouns vs. proper names). Performance in sentence comprehension was worse for complex sentences than for simpler sentences, and this effect was greater when the type of words in the memory load matched the type of words in the sentence. These results indicate that syntactic processing is not modular, instead suggesting that it relies on working memory resources that are used for other nonsyntactic processes. Further, the results indicate that similarity-based interference is an important constraint on information processing that can be overcome to some degree during language comprehension by using the coherence of language to construct integrated representations of meaning.

Forward inferences: From activation to long‐term memory

Past research has been inconsistent regarding the extent to which forward inferences are activated and encoded during reading. To investigate the prevalence and the time course of forward inferences, 3 different tasks were employed. In Experiment 1, participants’ naming times were facilitated to a probe word when it represented a predicted action, both when that action was highly predictable and when it was only moderately predictable. In Experiments 2 and 3, participants were slow to read a subsequent sentence that contradicted the intended inference, indicating that the inference had been encoded and retained in working memory in both the high‐and low‐predictability conditions. In Experiment 4, the results of a recall task suggest that the high‐predictability forward inferences were encoded into the long‐term memory representation of the text. These findings suggest that forward inferences may be more prevalent and more persistent than has been indicated previously.

Readers' sensitivity to linguistic cues in narratives: How salience influences anaphor resolution

Despite the general assumption that anaphoric inferences are necessary inferences, Levine, Guzmán, and Klin (2000) concluded that the probability of resolving noun phrase anaphors depends both on the degree of accessibility in memory of the antecedent concepts and the extent to which resolution is necessary to create a coherent discourse representation. Four experiments are presented in which the factors that influence readers’ standard of coherence are investigated. We examine the hypothesis that readers are more likely to resolve anaphors that are perceived as salient; salience was manipulated both with a syntactic focusing structure (wh- clefts) and with the addition of prenominal adjectival modifiers. The results of a probe recognition time task provide support for the hypothesis that a variety of linguistic cues serve asmental processing instructions (Givón, 1992), which instruct readers as to how much attention to devote to processing.

When Throwing a Vase Has Multiple Consequences: Minimal Encoding of Predictive Inferencest

In three experiments, we investigate the likelihood that predictive inferences are drawn when there is more than one consequence of the predictive context. Whereas a previous set of studies (Klin, Guzmán, & Levine, 1999) showed no facilitation of a naming probe (e.g., break) 500 ms after the predictive context (e.g., Steven threw the delicate vase), in Experiment 1 there was evidence of an inference 1500 ms after the predictive context. However, in Experiment 2, there was no evidence of an inference when the 1500-ms inter-stimulus interval contained additional text. To reduce task demands, the probe task was eliminated in Experiment 3. Readers slowed down on a line that contradicted the targeted inference, suggesting that they drew a predictive inference. We conclude that predictive inferences are more prevalent than has been assumed previously, but they may be minimally encoded when conditions are not optimal.

Timbre priming effects and expectation in melody

Abstract In this study, participants identified the timbre of pitches when they occurred in isolation, and again when they occurred appended to short melodies. For pitches congruent with the melody, timbre identification generally improved when the pitches were appended to the melody in comparison to when they occurred in isolation. In addition, the amount of improvement was broadly consistent with theoretical accounts of the degree to which the pitches were expected, given the preceding melody. This finding relates both to proposed interactions in processing between pitch and timbre, and to theoretical work regarding melodic expectations. It suggests that melodic expectations can be revealed implicitly, and is consistent with the idea that they operate at a relatively early stage of perceptual processing. In this study, priming effects were shown in listeners without musical training, demonstrating that expectations can develop in response to passive exposure to music, not only in response to formal training.

A fan effect in anaphor processing: effects of multiple distractors

Research suggests that the presence of a non-referent from the same category as the referent interferes with anaphor resolution. In five experiments, the hypothesis that multiple non-referents would produce a cumulative interference effect (i.e., a fan effect) was examined. This hypothesis was supported in Experiments 1A and 1B, with subjects being less accurate and slower to recognize referents (1A) and non-referents (1B) as the number of potential referents increased from two to five. Surprisingly, the number of potential referents led to a decrease in anaphor reading times. The results of Experiments 2A and 2B replicated the probe-recognition results in a completely within-subjects design and ruled out the possibility that a speeded-reading strategy led to the fan-effect findings. The results of Experiment 3 provided evidence that subjects were resolving the anaphors. These results suggest that multiple non-referents do produce a cumulative interference effect; however, additional research is necessary to explore the effect on anaphor reading times.

Negated concepts interfere with anaphor resolution

Abstract Across three experiments, we studied whether the mental representations of negated concepts are suppressed. In two reading-time experiments, we tested whether the presence of a negated nonreferent distractor (e.g., Justin bought a mango but not an apple. He ate the fruit.) interfered with the process of anaphor resolution. We found evidence that highly-typical category exemplars (e.g., apple) in the negated nonreferent role interfere with anaphor comprehension; evidence regarding less-typical category exemplars was mixed. In a third experiment, participants read brief passages like those from the prior experiments and their memory for the category exemplars was tested in a surprise cued-recall task. Once again, we found evidence that negated nonreferents are considered during anaphor resolution. These results are inconsistent with a theoretical perspective that posits that negation of a concept obligatorily leads to suppression of that concept. Instead, we argue that the comprehension of negation will be dictated by its pragmatic role.

Rapid communication The mental number line dominates alternative, explicit coding of number magnitude.

Numerical judgments are facilitated for left-space responses to a smaller number and right-space responses to a larger number (the spatial–numerical association of response codes, SNARC, effect). Despite support for a mental number line (i.e., spatial) explanation of the SNARC effect, this account has been challenged by an intermediate-coding theory that makes use of a polarity-correspondence principle. The latter is a general explanatory framework whereby stimulus and response dimensions are represented in a categorical, binary manner, with complementary categories coded as having either positive or negative polarity. When stimulus and response polarity match, responding is facilitated. In the present experiment we pitted explicitly presented close–far coding against an implicit mental number line (i.e., left–right coding). Subjects categorized numbers (1, 4, 6, and 9) as greater or less than a standard (5) using keys defined only as close to and far from a starting key. We found that, despite instructing subjects to use a close–far coding scheme, they exhibited a typical SNARC effect, with small-number responses facilitated on the left and large-number responses on the right. These results are discussed in the context of results supporting the polarity explanation and with respect to representational pluralism.

The Effect of Spoilers on the Enjoyment of Short Stories

Recent research has provided evidence that the information provided before a story—a spoiler—may increase the enjoyment of that story, perhaps by increasing the processing fluency experienced during reading. In one experiment, we tested the reliability of these findings by closely replicating existing methods and the generality of these findings by using different stories. We also examined the role of processing fluency in the effect of spoilers by measuring reading time. Finally, we examined the influence of spoilers presented mid-story, after a reader has had a chance to get invested in the story. We found that spoilers presented before a story reduced enjoyment, whereas those presented mid-story had no discernable effect. The difference between our findings and those in the literature are discussed with respect to types of spoilers as well as potentially critical methodological factors.

Expressive intent, ambiguity, and aesthetic experiences of music and poetry

A growing number of studies are investigating the way that aesthetic experiences are generated across different media. Empathy with a perceived human artist has been suggested as a common mechanism [1]. In this study, people heard 30 s excerpts of ambiguous music and poetry preceded by neutral, positively valenced, or negatively valenced information about the composers or author’s intent. The information influenced their perception of the excerpts—excerpts paired with positive intent information were perceived as happier and excerpts paired with negative intent information were perceived as sadder (although across intent conditions, musical excerpts were perceived as happier than poetry excerpts). Moreover, the information modulated the aesthetic experience of the excerpts in different ways for the different excerpt types: positive intent information increased enjoyment and the degree to which people found the musical excerpts to be moving, but negative intent information increased these qualities for poetry. Additionally, positive intent information was judged to better match musical excerpts and negative intent information to better match poetic excerpts. These results suggest that empathy with a perceived human artist is indeed an important shared factor across experiences of music and poetry, but that other mechanisms distinguish the generation of aesthetic appreciation between these two media.
