Ageism,Sensation-Seeking,and Risk-Taking Behavior in Young Adults

The research investigated the relationships among ageism, sensation-seeking, and risk-taking in young adults. Recent research has shown that young adults reporting higher levels of ageist attitudes and ageist behaviors also report higher levels of risk-taking in daily life than those with less ageist attitudes and behaviors (Popham et al. in press). The results are consistent with terror management theory; young adults may attempt to buffer their death anxiety by seeking out experiences that make them feel strong and invulnerable (i.e., taking risks). In contrast, prior research has shown that there is a link between risk-taking and sensation-seeking and that individuals may be biologically predisposed to be high sensation-seekers (Zuckerman Behavioural and Brain Sciences 7:413–471, 1984; Neuropsychobiology 13:121–128, 1985). In a study with 475 undergraduates, we investigated the relationships among ageism, sensation-seeing, and risk-taking behavior. The results showed that ageist behavior and two dimensions of sensation-seeking (i.e., Disinhibition and Experience Seeking) were significant predictors of risk-taking. Implications for practical approaches to reduce risk-taking in young adults are discussed.     

Different time courses of integrative semantic processing for plural and singular nouns: implications for theories of sentence processing

The research investigated the time course of integrative semantic processing during sentence processing. Reading time was measured on sentences containing an NP composed of an adjective and a noun whose combined meaning was plausible or anomalous (Experiment 1) or was typical or atypical (Experiment 2). The noun in the NP was either plural or singular. Plural nouns were expected to be more rapidly integrated with a preceding adjective than singular nouns because plural nouns can be ruled out as the first noun in a noun compound more rapidly than singular nouns. The results confirmed this prediction, showing that the effects of semantic plausibility and typicality were observed immediately during the processing of plural nouns, but were observed at a delay following the processing of singular nouns. Implications for theories of sentence processing are discussed.     

American English Usage Frequencies for Noun Phrase and Tensed Sentence Complement-Taking Verbs

The present research documents the American English usage frequencies for 136 verbs that occur with noun phrase and tensed sentence complements (e.g., accepted, noun phrase complement: The student knew the answer yesterday, tensed sentence complement: The student knew the answer was correct). This class of verbs has been the focus of numerous empirical studies investigating how syntactic ambiguity is resolved during language comprehension (Ferreira & Henderson, 1990; Garnsey, Pearlmutter, Myers, & Lotocky, 1997; Holmes, Stowe, & Cupples, 1989; Kennedy, Murray, Jennings, & Reid, 1989; Kennison, 1995; Rayner & Frazier, 1987; Trueswell, Tanenhaus, & Kello, 1993). The frequencies for noun phrase complements, tensed sentence complements, prepositional phrase complements, infinitival complements, and other usages are provided, as well as the frequencies with which specific verbs occur with the overt complementizer that in tensed sentence complements.     

Guessing Strategies, Aging, and Bias Effects in Perceptual Identification

In the typical single-stimulus perceptual identification task, accuracy is improved by prior study of test words, a repetition priming benefit. There is also a cost, inasmuch as previously studied words are likely to be produced (incorrectly) as responses if the test word is orthographically similar but not identical to a studied word. In two-alternative forced-choice perceptual identification, a test word is flashed and followed by two alternatives, one of which is the correct response. When the two alternatives are orthographically similar, test words identical to previously studied items are identified more accurately than new words (a benefit) but tests words orthographically similar to studied words are identified less accurately than new words (a cost). Ratcliff and McKoon (in press) argue that these are bias effects that arise in the decision stage of word identification. We report five experiments that examined the alternative hypothesis that these bias effects arise from postperceptual guessing strategies. In single-stimulus perceptual identification, repetition priming benefits were equally great for young and older adults who claimed to use deliberate guessing strategies and those who did not (Experiment 1). In contrast, only groups of young and older people who claimed to deliberately guess studied words in a two-alternative forced-choice task (Experiments 2 and 5) showed reliable benefits and costs. Costs and benefits were abolished in the two-alternative forced-choice task when a very long study list was used, presumably because the increased retrieval burden made the use of deliberate guessing strategies less attractive (Experiment 3). Under conditions similar to those of Experiment 3, repetition priming was observed in single-stimulus perceptual identification (Experiment 4). These results are consistent with the view that costs and benefits in the forced-choice perceptual identification task arise from deliberate guessing strategies but that those in the single-stimulus task do not. The possibility that the observed relationship between strategy reports and priming effects reflects erroneous postexperimental assessments of strategies by participants is also considered.     

Cursing as a Form of Risk-Taking

The research investigated the relationships among cursing, risk-taking (i.e., drinking, smoking, using illegal drugs, and engaging in risky sexual behavior), and personality variables that have been shown to be related to risk-taking (i.e., sensation-seeking and Big-Five personality factors). In a study with 360 participants, the results showed that for both men and women, those who took more risks in daily life also reported cursing more than others. Men and women who scored higher on disinhibition and experience-seeking reported taking more risks and cursing more than others. Men and women who scored higher in conscientiousness reported taking fewer risks and reported cursing less than others. The results of a multiple regression analyses showed that frequency of curse word usage was predicted by disinhibition and risk-taking, and cursing behavior was predicted by disinhibition, risk-taking, and emotional stability. Overall men reported taking more risks and cursing more often than women; however, in the multiple regression analyses, participant sex was not among the significant predictors. Theoretical implications and directions for future research are discussed.     

Not your parents' test scores: cohort reduces psychometric aging effects

Increases over birth cohorts in psychometric abilities may impact effects of aging. Data from 2 cohorts of the Long Beach Longitudinal Study, matched on age but tested 16 years apart, were modeled over ages 55-87 to test the hypothesis that the more fluid abilities of reasoning, list and text recall, and space would show larger cohort differences than vocabulary. This hypothesis was confirmed. At age 74, average performance estimates for people from the more recently born cohort were equivalent to those of people from the older cohort when they were up to 15 years younger. This finding suggests that older adults may perform like much younger ones from the previous generation on fluid measures, indicating higher levels of abilities than expected. This result could have major implications for the expected productivity of an aging workforce as well as for the quality of life of future generations. However, cohort improvements did not mitigate age declines.     

The Role of Age of Acquisition in Bilingual Word Translation: Evidence from Spanish-English Bilinguals

The present research tested the hypothesis that the age at which one’s first language (L1) words are learned influences language processing in bilinguals. Prior research on bilingual language processing by Kroll and colleagues has suggested that memory links between L1 words and conceptual representations are stronger than memory links between one’s second language (L2) word and conceptual representations. We hypothesized that the strengths of memory links between L1 words and conceptual representations are stronger for words learned early in life than for words learned later in life. Support for the hypothesis was obtained in bilingual translation experiment with 36 Spanish–English bilinguals. Participants translated L1 words into L2 and L2 words into L1. Half of the L1 words were learned early in childhood (early AoA words), and half were learned later in life (late AoA words). The L2 words were translation equivalents of the L1 words tested; the average age at which L2 words were learned was age 7. Target words were presented either in random order or blocked by semantic category. Translation times were longer when trials were blocked by semantic category (i.e., categorical interference) occurred only when early AoA L1 words were translated into L2. Implications for current models of bilingual memory are discussed.     

Comprehending pronouns: a role for word-specific gender stereotype information

The research investigated how word-specific gender stereotype information can be used during language comprehension. In a rating study, the gender stereotypes for 405 noun and noun compounds were assessed. From these norms, 32 words strongly stereotyped to refer mostly to males and 32 words strongly stereotyped to refer mostly to females were selected and used in a reading experiment. Comprehenders read pairs of sentences. The subject of the first sentence was a gender stereotyped word (e.g., executive or secretary). The subject of the second sentence was either the pronoun he or she. Reading time was significantly longer when gender of the pronoun mismatched the gender stereotype of the antecedent than when the genders of pronoun and antecedent matched. This gender mismatch effect occurred on the two regions immediately following the region containing the pronoun. The results indicated that word-specific gender stereotypes can influence coreference resolution of pronouns.     

Two Assessments of American Usage Frequencies for Ninety-Seven Sentence Complement-Taking Nouns

Two studies documented the American English usage frequencies for ninety-seven nouns that occur with sentence complements (e.g., rumor, The rumor that the student cheated ¨). An established usage preference methodology was used (see Connine, Ferreira, Jones, Clifton, & Frazier, 1984; Kennison, 1999).² In Study 1, participants completed short fragments that did not contain the overt complementizer that, as in The rumor ¨ In Study 2, participants completed short sentence fragments that contained the overt complementizer, as in The rumor that ¨ The results showed that when the complementizer was absent (Study 1), bare (i.e., unmodified) usages and prepositional phrase usages were frequently observed. In contrast, sentence complement and relative clause usages were rarely observed. When the complementizer was present (Study 2), the frequency of sentence complement and relative clause usages varied. The estimates of usage frequency obtained in these studies are intended to be a resource for language comprehension researchers.     

On the conditions necessary for obtaining argument structure complexity effects.

Schmauder (1991), studying eye movements during reading, cross-modal naming, and cross-modal lexical decision (CMLD) tasks, failed to find evidence of verb argument structure complexity as Shapiro, Zurif, and Grimshaw (1987) had reported for the CMLD task. Shapiro, Brookins, Gordon, and Nagel (1991) suggested that Schmauder did not detect the effect in the CMLD task because the monosyllabic secondary lexical decision (LD) probes she used did not produce enough processing load to detect an effect of argument structure complexity. The present experiment compared the LD probes used by Schmauder with the LD probes used by Shapiro et al. (1987) and failed to find any evidence for the argument structure complexity effect for either type of probe.
