On strategies for processing relative clauses: A comparison of children and adults

Adults were tested for the way in which they process four types of subject and object relative clauses. The results support an anti-interruption and anti-rearrangement constraint that has been proposed by Slobin. The reason why interruption and rearrangment of linguistic units is hard for adults is explained in terms of language-processing strategies that they are hypothesized to be using, in particular the Adjacency strategy. Adult behavior is compared to the performance of 4- and 5-year-old children in a previous study. The results of these two studies support the claim that children and adults are following the same strategies in processing these sentences, and that the difference between them is in which strategies they rely most heavily on, and, consequently, which sentences they make the most mistakes on.This research was supported by a Grant-in-Aid from the Graduate School of the University of Minnesota.This paper was presented at the Thirty-sixth Summer Meeting of the Linguistic Society of American, on July 29, 1974, in Amherst, Massachusetts.     

The functional independence of response latency and accuracy: Implications for the concept of conceptual tempo

Kagan (1965a) developed the concepts of impulsive and reflective cognitive styles (conceptual tempo) to add a new dimension to the understanding and assessment of human intelligence. Although latency (the principal component of conceptual tempo) is negatively correlated with academic performance, it may not be necessary to modify latency in order to modify accuracy. With 40 disadvantaged preschool children, it was found that reinforcing long latencies in choice tasks did not increase accuracy and vice versa, and that reinforcing both long latencies and accuracy was no more effective than reinforcing accuracy alone. These data were used to question the usefulness of the construct of conceptual tempo.This article is based on a master's thesis prepared by the first author under the supervision of the second author.     

When Job Candidates Are “Hard-” Versus “Easy-to-Get”: Effects of Candidate Availability on Employment Decisions1

Research on interpersonal attraction suggests that being elusive or “playing hard-to-get” is effective for increasing one's desirability and the likelihood of being selected as a dating partner. The following two studies explored the effects of this hard-to-get phenomenon in an employment decision setting. Both college students (Experiment 1) and professional recruiters (Experiment 2) reviewed application materials that conveyed that a candidate was either hard- (e. g., considering other job opportunities) or easy-to-get (e. g., not considering other opportunities) and then indicated their evaluations of these candidates. In both studies, being hard-to-get affected the interviewers’ judgments. However, this effect was moderated by the type of rationale given for being hard- or easy-to-get, as well as the objective qualifications (GPA) information. In addition, recruiter sex and candidate gender differences were explored. Male recruiters’ evaluations of application materials were more lenient than were females’ evaluations.     

Choice and conditioned reinforcement.

A potential weakness of one formulation of delay-reduction theory is its failure to include a term for rate of conditioned reinforcement, that is, the rate at which the terminal-link stimuli occur in concurrent-chains schedules. The present studies assessed whether or not rate of conditioned reinforcement has an independent effect upon choice. Pigeons responded on either modified concurrent-chains schedules or on comparable concurrent-tandem schedules. The initial link was shortened on only one of two concurrent-chains schedules and on only one of two corresponding concurrent-tandem schedules. This manipulation increased rate of conditioned reinforcement sharply in the chain but not in the tandem schedule. According to a formulation of delay-reduction theory, when the outcomes chosen (the terminal links) are equal, as in Experiment 1, choice should depend only on rate of primary reinforcement; thus, choice should be equivalent for the tandem and chain schedules despite a large difference in rate of conditioned reinforcement. When the outcomes chosen are unequal, however, as in Experiment 2, choice should depend upon both rate of primary reinforcement and relative signaled delay reduction; thus, larger preferences should occur in the chain than in the tandem schedules. These predictions were confirmed, suggesting that increasing the rate of conditioned reinforcement on concurrent-chains schedules may have no independent effect on choice.     

A study of paranormal belief, magical ideation as an index of schizotypy and cognitive style

This study examined the proposal that the association between paranormal belief and magical ideation may be mediated by distinctive cognitive styles for schizotypes as compared to believers in the paranormal. Schizotypes were found to differ from an atypical group of believers in the paranormal and to resemble schizophrenics in terms of cognitive style. Believers expressed a cognitive style reliant on notions of personal responsibility while schizotypes emphasised the role of randomness. Believers differed from schizotypes on more deviant aspects of schizotypy measures yet unexpectedly these groups did not differ on specific facets of paranormal belief. It is tentatively proposed that for some people certain paranormal beliefs represent a cognitive ‘defence’ against acceptance of the uncertainty of life events, while for others paranormal belief may be indicative of psychopathology.     

Testing the status-legitimacy hypothesis: Predicting system justification using objective and subjective socioeconomic status in China and the United States

The status-legitimacy hypothesis proposes that those who are most disadvantaged by unequal social systems are even more likely than members of more advantaged groups to provide ideological support for the very social system that is responsible for their disadvantages. Li, Yang, Wu, and Kou (2020, Personality and Social Psychology Bulletin) sought to expand the generalizability of this hypothesis by testing it in China, addressing inconsistencies surrounding the empirical support for this hypothesis by postulating that the construct of status should be separated into an objective and subjective status marker. They reported that objective socioeconomic status (SES; income and education) negatively predicted system justification, while subjective SES positively predicted system justification. In the present study we attempt to replicate and extend the work of Li et al. in a cross-cultural comparison of demographic stratified quota online samples in China and the United States. We test the status-legitimacy hypothesis using objective and subjective SES to predict system justification using cross-sectional and cross-lagged regression analyses. We received partial support for Li et al.'s findings. Specifically, subjective SES positively predicted system justification for both societies during cross-sectional and cross-lagged longitudinal analyses. However, we failed to replicate Li et al.'s findings surrounding objective SES in China during cross-sectional and cross-lagged analyses.
