Idiom literality judgments in younger and older adults: Age-related effects in resolving semantic interference.

To study age effects in the resolution of idiomatic semantic ambiguity, we focus on decomposability, the extent to which a literal reading of an idiom's words shares meaning with its figurative interpretation. Younger and older adults judged whether decomposable and nondecomposable idioms and nonidioms had a literal interpretation. Older adults were slower at making literality judgments and more sensitive to conflicts between literal and figurative meanings. The results support claims of decompositional analysis of idioms during later processing stages and of obligatory activation of figurative meanings. They also lend support to research that has shown age-related effects in ambiguity resolution. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Conceptual knowledge in the interpretation of idioms.

The authors examined how people determine the contextual appropriateness of idioms. In Experiment 1, idioms referring to the same temporal stage of a conceptual prototype were judged to be more similar in meaning than idioms referring to different temporal stages. In Experiment 2, idioms in a prototypical temporal sequence were more meaningful than idioms in sentences that violated the temporal sequence. In Experiment 3, idioms referring to the same stage of a conceptual prototype were differentiable on the basis of conceptual information. The conceptual coherence between idioms and contexts facilitated the processing speed of idioms in Experiment 4. Experiment 5 showed that speakers can recover the underlying conceptual metaphors that link an idiom to its figurative meaning. Experiment 6 showed that the metaphoric information reflected in the lexical makeup of idioms also determined the metaphoric appropriateness of idioms in certain contexts.

Idiom processing in schizophrenia: Literal implausibility saves the day for idiom priming.

Schizophrenia patients have difficulty processing nonliteral forms of discourse such as idiomatic expressions. We hypothesized that schizophrenia patients would show impaired idiom processing for literally plausible idioms (e.g., kick the bucket) but not for literally implausible idioms (e.g., be on cloud nine). Thirty-two patients and 36 controls listened to sentences containing literally plausible and implausible idioms and made lexical decisions about idiom-related or literal-related targets. Schizophrenia patients showed reduced priming for literally plausible idioms but intact priming for literally implausible idioms compared with controls. Both groups showed evidence of literal word priming. These results are consistent with the notion that schizophrenia patients make normal use of context under conditions that minimize the need for controlled processing.

Information processing speed and sentence comprehension in Parkinson's disease.

This study tests the hypothesis that sentence comprehension difficulty in Parkinson's disease (PD) is related in part to altered information processing speed that plays a crucial role in grammatical processing. The authors measured information processing speed in 32 PD patients without dementia using a lexical list-priming paradigm in which the interstimulus interval (ISI) between the prime and the target varied. Sentence comprehension accuracy was also assessed in 22 of these patients. Sentence comprehension accuracy for object-relative center-embedded sentences was impaired in a subgroup of PD patients. This subgroup of PD patients primed at an abnormally long ISI. Similarly, only PD patients who primed at a long ISI had greater difficulty understanding sentences with an object-relative clause than a subject-relative clause. Findings suggest that slowed information processing speed contributes to sentence comprehension difficulty in PD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eye movements of young and older adults during reading.

The eye movements of young and older adults were tracked as they read sentences varying in syntactic complexity. In Experiment 1, cleft object and object relative clause sentences were more difficult to process than cleft subject and subject relative clause sentences; however, older adults made many more regressions, resulting in increased regression path fixation times and total fixation times, than young adults while processing cleft object and object relative clause sentences. In Experiment 2, older adults experienced more difficulty than young adults while reading cleft and relative clause sentences with temporary syntactic ambiguities created by deleting the that complementizers. Regression analyses indicated that readers with smaller working memories need more regressions and longer fixation times to process cleft object and object relative clause sentences. These results suggest that age-associated declines in working memory do affect syntactic processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Processing causal and diagnostic statements in discourse.

Diagnostic statements (e.g., It is raining because the streets are wet) take longer to read than causal statements (e.g., The streets are wet because it is raining). The authors present 4 experiments investigating this phenomenon. In Experiment 1, a reading-time study, the authors demonstrate that this difficulty is reversed when a more complex mental model is cued through the use of phrases like John thinks that and John says that. Experiment 2 shows that the use of a modal construction (e.g., Perhaps it is raining because the streets are wet) makes the processing of diagnostics as easy as processing causals but does not disadvantage causals. The authors explain the pattern of results by proposing that readers build the simplest possible discourse representation during interpretation and that readers adopt a specific pattern of semantic interpretation. These proposals are tested and verified in Experiments 3 and 4. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The referents of trait inferences: The impact of trait concepts versus actor–trait links on subsequent judgments.

The authors investigated the hypothesis that when trait inferences refer to abstract behavior labels they act as a general interpretation frame and lead to assimilation in subsequent judgments of an ambiguous target, whereas when they refer to a specific actor–trait link they will be used as a scale anchor and lead to contrast. Similar to G. B. Moskowitz and R. J. Roman's (see record 1992-31124-001) study, participants who were instructed to memorize trait-implying sentences showed assimilation, and participants who were instructed to form an impression of the actors in these sentences showed contrast. However, exposure to trait-implying sentences that described actors with real names and were accompanied with photos of the actors resulted in contrast under both memorization and impression instructions (Experiment 1). Furthermore, contrast ensued when trait-implying sentences were accompanied with information that suggested a person attribution, whereas assimilation ensued when that information suggested a situation attribution, independent of processing goals (Experiment 2). These findings are interpreted as support for referent-based explanations of the consequences of trait inferences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of foveal processing difficulty on the perceptual span in reading: Implications for attention and eye movement control.

Two experiments were conducted to examine the effects of foveal processing difficulty on the perceptual span in reading. Subjects read sentences while their eye movements were recorded. By changing the text contingent on the reader's current point of fixation, foveal processing difficulty and the availability of parafoveal word information were independently manipulated. In Experiment 1, foveal processing difficulty was manipulated by lexical frequency, and in Experiment 2 foveal difficulty was manipulated by syntactic complexity. In both experiments, less parafoveal information was acquired when processing in the fovea was difficult. We conclude that the perceptual span is variable and attentionally constrained. We also discuss the implications of the results for current models of the relation between covert visual–spatial attention and eye movement control in reading.

Effects of age, speed of processing, and working memory on comprehension of sentences with relative clauses.

Two hundred participants, 50 in each of four age ranges (19–29, 30–49, 50–69, 70–90) were tested for working memory, speed of processing, and the processing of sentences with relative clauses. In Experiment 1, participants read four sentence types (cleft subject, cleft object, subject-subject, subject-object) in a word-by-word, non-cumulative, self-paced reading task and made speeded plausibility judgments about them. In Experiment 2, participants read two types of sentences, one of which contained a doubly center embedded relative clause. Older participants' comprehension was less accurate and there was age-related slowing of online processing times in all but the simplest sentences, which increased in syntactically complex sentences in Experiment 1. This pattern suggests an age-related decrease in the efficiency of parsing and interpretation. Slower speed of processing and lower working memory were associated with longer online processing times only in Experiment 2, suggesting that task-related operations are related to general speed of processing and working memory. Lower working memory was not associated with longer reading times in more complex sentences, consistent with the view that general working memory is not critically involved in online syntactic processing. Longer online processing at the most demanding point in the most demanding sentence was associated with better comprehension, indicating that it reflects effective processing under some certain circumstances. However, the poorer comprehension performance of older individuals indicates that their slower online processing reflects inefficient processing even at these points.

Processing idiomatic expressions: Effects of semantic compositionality.

Three experiments tested the main claims of the idiom decomposition hypothesis: People have clear intuitions on the semantic compositionality of idiomatic expressions, which determines the syntactic behavior of these expressions and how they are recognized. Experiment 1 showed that intuitions are clear only for a very restricted number of expressions, but for the majority of idioms, they are not consistent across speakers. Experiment 2 failed to support the claim that semantic compositionality influences the syntactic flexibility of idioms. Finally, Experiment 3 showed that idioms are more quickly recognized than their literal counterparts, regardless of compositionality and syntactic flexibility. All of the findings were at odds with the tenets of the idiom decomposition hypothesis. The theoretical implications of the results with respect to idiom processing and the notion of compositionality are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Breaking the waves: Age differences in electrical brain activity when reading text with distractors.

The authors tested whether older adults have greater difficulty than younger adults in ignoring task-irrelevant information during reading as a result of age-related decline in inhibitory processes. Participants were shown target sentences containing distractor words. They were instructed to read aloud each sentence and ignore distractors. The N400 event-related potential (ERP) was used to measure the extent of semantic processing of target and distracting information. It showed that younger adults semantically processed both target and distracting material, whereas online processing of target sentences in older adults was disrupted by the distractors. In older adults, memory for target information related to their susceptibility to distraction and inhibition efficiency. Implications for age-differences in inhibitory control, working memory, and resource capacity are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of connectives on young readers' processing and comprehension of text.

Connectives are cohesive devices that signal the relations between clauses and are critical to the construction of a coherent representation of a text's meaning. The authors investigated young readers' knowledge, processing, and comprehension of temporal, causal, and adversative connectives using offline and online tasks. In a cloze task, 10-year-olds were more accurate than 8-year-olds on temporal and adversative connectives, but both age groups differed from adult levels of performance (Experiment 1). When required to rate the “sense” of 2-clause sentences linked by connectives, 10-year-olds and adults were better at discriminating between clauses linked by appropriate and inappropriate connectives than were 8-year-olds. The 10-year-olds differed from adults only on the temporal connectives (Experiment 2). In contrast, online reading time measures indicated that 8-year-olds' processing of text is influenced by connectives as they read, in much the same way as 10-year-olds'. Both age groups read text more quickly when target 2-clause sentences were linked by an appropriate connective compared with texts in which a connective was neutral (and), inappropriate to the meaning conveyed by the 2 clauses, or not present (Experiments 3 and 4). These findings indicate that although knowledge and comprehension of connectives is still developing in young readers, connectives aid text processing in typically developing readers.

Dissociation between syntactic and semantic processing during idiom comprehension.

Syntactic and semantic processing of literal and idiomatic phrases were investigated with a priming procedure. In 3 experiments, participants named targets that were syntactically appropriate or inappropriate completions for semantically unrelated sentence contexts. Sentences ended with incomplete idioms (kick the…) and were biased for either a literal (ball) or an idiomatic (bucket) completion. Syntactically appropriate targets were named more quickly than inappropriate ones for both contextual biases, suggesting that syntactic analysis occurs for idioms. In a final experiment, targets were either concrete (expected) or abstract (unexpected) nouns. For literal sentences, the abstract targets were named more slowly than the concrete targets. In contrast, there was no concreteness effect for idiomatic sentences, suggesting that the literal meaning of the idiom is not processed. Overall, the results provide evidence for dissociation between syntactic and semantic processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Lexical ambiguity resolution in good and poor comprehenders: An eye fixation and self-paced reading study in primary school children.

To investigate the use of context and monitoring of comprehension in lexical ambiguity resolution in children, the authors asked 10- to 12-year-old good and poor comprehenders to read sentences consisting of 2 clauses, 1 containing the ambiguous word and the other the disambiguating information. The order of the clauses was reversed so that disambiguating information either preceded or followed the ambiguous word. Context use and comprehension monitoring were examined by measuring eye fixations (Experiment 1) and self-paced reading times (Experiment 2) on the ambiguous word and disambiguating region. The results of Experiment 1 and 2 showed that poor comprehenders made use of prior context to facilitate lexical ambiguity resolution as effectively as good comprehenders but that they monitored their comprehension less effectively than good comprehenders. Good comprehenders corrected an initial interpretation error on an ambiguous word and restored comprehension once they encountered the disambiguating region. Poor comprehenders failed to deal with this type of comprehension failure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age, working memory, and on-line syntactic processing in sentence comprehension.

One hundred twenty-seven individuals who ranged in age from18 to 90 years were tested on a reading span test and on measures of on-line and off-line sentence processing efficiency. Older participants had reduced working-memory spans compared with younger participants. The on-line measures were sensitive to local increases in processing load, and the off-line measures were sensitive to the syntactic complexity of the sentences. Older and younger participants showed similar effects of syntactic complexity on the on-line measures. There was some evidence that older participants were more affected than younger participants by syntactic complexity on the off-line measures. The results support the hypothesis that on-line processes involved in recognizing linguistic forms and determining the literal, preferred, discourse-coherent meaning of sentences constitute a domain of language processing that relies on its own processing resource or working-memory system.

Repetition Blindness: Out of Sight or Out of Mind?

Does repetition blindness represent a failure of perception or of memory? In Experiment 1, participants viewed rapid serial visual presentation (RSVP) sentences. When critical words (C1 and C2) were orthographically similar, C2 was frequently omitted from serial report; however, repetition priming for C2 on a postsentence lexical decision task was equivalent whether or not C1 was similar to C2. In Experiment 2, participants monitored RSVP sentences for a predetermined target. Participants frequently failed to detect the target when it was preceded by an orthographically similar word. In Experiment 3, the authors investigated the role of the attentional blink in this effect. These experiments suggest that repetition blindness is a failure of conscious perception, consistent with predictions of the token-individuation hypothesis.

Accessing Distant Premise Information: How Memory Feeds Reasoning.

According to current psychological models of deduction, people can draw inferences on the basis of information that they receive from different sources at different times. In 3 reading-comprehension experiments, the authors demonstrated that premises that appear far apart in a text (distant) are not accessed and are therefore not used as a basis for logical inferences (Experiment 1), unless the premises are reinstated by a contextual cue (Experiment 2). In Experiment 3, the authors investigated whether these deductions are then integrated into the reader's situation model of the text. The results are interpreted in terms of a collaboration between memory-based text processing and higher level schema-driven logical reasoning.

Implicit memory bias for threat-relevant information in individuals with generalized social phobia.

The authors used a noise judgment task to investigate implicit memory bias for threat in individuals with generalized social phobia (GSP). Participants first heard neutral sentences (e.g., "The manual tells you how to set up the tent.") and social-threat sentences (e.g., "The classmate asks you to go for drinks."). Implicit memory for these sentences was then tested by asking participants to rate the volume of noise accompanying the presentation of these "old" sentences intermixed with "new" sentences that had not been previously presented. Implicit memory for old sentences is revealed when participants rate the noise accompanying old sentences as less loud than the noise accompanying new sentences. Those with GSP demonstrated an implicit memory bias for social-threat sentences, whereas controls did not. This differential priming effect suggests that information about threat may be automatically accessed in GSP. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What proverb understanding reveals about how people think.

The ability to understand proverbial sayings, such as a rolling stone gathers no moss has been of great interest to researchers in many areas of psychology. Most psychologists assume that understanding the figurative meanings of proverbs requires various kinds of higher order cognitive abilities. The authors review the findings on proverb interpretation to examine the question of what proverb use and understanding reveals about the ways normal and dysfunctional individuals think. The widely held idea that failure to provide a figurative interpretation of a proverb necessarily reflects a deficit in specialized abstract thinking is rejected. Moreover, the ability to correctly explain what a proverb means does not necessarily imply that an individual can think abstractly. Various empirical evidence, nonetheless, suggests that the ability to understand many proverbs reveals the presence of metaphorical schemes that are ubiquitous in everyday thought.
