Two priming experiments demonstrated exogenous attentional persistence to the fundamental auditory dimensions of frequency (Experiment 1) and time (Experiment 2). In a divided-attention task, participants responded to an independent dimension, the identification of three-tone sequence patterns, for both prime and probe stimuli. The stimuli were specifically designed to parallel the local-global hierarchical letter stimuli of [Navon D. (1977). Forest before trees: The precedence of global features in visual perception. Cognitive Psychology, 9, 353-383] and the task was designed to parallel subsequent work in visual attention using Navon stimuli [Robertson, L. C. (1996). Attentional persistence for features of hierarchical patterns. Journal of Experimental Psychology: General, 125, 227-249; Ward, L. M. (1982). Determinants of attention to local and global features of visual forms. Journal of Experimental Psychology: Human Perception and Performance, 8, 562-581]. The results are discussed in terms of previous work in auditory attention and previous approaches to auditory local-global processing.  相似文献

The empirical and theoretical work of both operant and cognitive researchers has increasingly appealed to evolutionary concepts. In particular, both traditional operant studies of extinction-induced behavior and cognitive investigations of creativity and problem solving converge on the fundamental evolutionary principles of variation and selection. These contemporary developments and their implications for the alleged preparadigmatic status of psychology are discussed.  相似文献

A response to Michael's (1980) presidential address to the Association for Behavior Analysis is presented. The position is taken that in many instances we have failed to adopt a behavioral approach to dealing with problems within our field concomitant with the shift from an emphasis on behaviorism and a science of behavior to technology. It is argued that we need to be sensitive to the data and consider the contingencies that are operating within the culture. A general strategy and some tactics are presented to acquire and maintain behavioral skills.  相似文献

This paper discusses some of the difficulties that arise in the practical applications of theories derived from specific experimental settings. Nevin's metaphoric extension of the physical concept of momentum to modifying behavior (i.e., behavioral momentum) is used as a recent example. Problems in the application of behavioral momentum are discussed, alternative analyses are offered, and methods for further testing the process are suggested. ©1997 John Wiley & Sons, Ltd.  相似文献

The auditory sensitivity of the chinchilla was measured by both a behavioral and auditory evoked-response (AER) procedure. There was no significant difference in either the waveform or the threshold of the AER recorded over the tentorium from awake and anesthetized chinchillas. The chinchilla threshold for pure tones appears to be more sensitive when measured by the behavioral technique than by the AER method. Both the AER and behavioral response of three chinchillas exposed to a 105 dB SPL octave band of noise centered at 2 KHz for 3 h shifted markedly after the exposure. However, the difference between the AER and behavioral response threshold was reduced or absent. During the process of recovery the difference between the two responses begins to reappear.  相似文献

ABSTRACT— Research across various disciplines has demonstrated that social exclusion has devastating psychological, emotional, and behavioral consequences. Excluded individuals are therefore motivated to affiliate with others, even though they may not have the resources, cognitive or otherwise, to do so. The current research explored whether nonconscious mimicry of other individuals—a low-cost, low-risk, automatic behavior—might help excluded individuals address threatened belongingness needs. Experiment 1 demonstrated that excluded people mimic a subsequent interaction partner more than included people do. Experiment 2 showed that individuals excluded by an in-group selectively (and nonconsciously) mimic a confederate who is an in-group member more than a confederate who is an out-group member. The relationship between exclusion and mimicry suggests that there are automatic behaviors people can use to recover from the experience of being excluded. In addition, this research demonstrates that nonconscious mimicry is selective and sensitive to context.  相似文献

Pigeons pecked two keys in a probability matching situation in which four two-peck sequences were intermittently reinforced: left-left, left-right, right-left and right-right. In Phase 1, relative reinforcement rate was varied with respect to the first response of a sequence: reinforcers were differentially assigned for left-left and left-right sequences as opposed to right-left and right-right sequences. The second response of reinforced sequences occurred equally on the left and right keys across conditions. In Phase II, relative reinforcement rate was varied for sequences that involve an alternation as opposed to those that did not. The relative outputs of the different sequences matched the relative reinforcement rates for the different sequences in both phases. Relative response rates for key pecks did not always match relative reinforcement rates. The intertrial interval separating responses was varied in both phases; increases in the intertrial interval affected the relative frequency of different sequences. The results demonstrate that response sequences acted as functional units influencing choice and thus support a structural account of choice. At the same time, the matching of relative sequence proportion and relative reinforcement rate supports a matching account.  相似文献

Task persistence, measured by a composite score of independent teacher, tester and observer reports, was examined using behavioral genetic analysis. Participants included 92 monozygotic and 137 same-sex dizygotic twin pairs in Kindergarten or 1st grade (4.3 to 7.9 years old). Task persistence was widely distributed, higher among older children, positively associated with standardized tests of cognitive performance and achievement, and negatively associated with parents', teachers' and observers' reports of behavioral problems. Cross-sectional analysis indicated a strong developmental shift from shared environment variance among younger children to additive genetic variance in older children.  相似文献

Previous research on the components of the emotional response employing factor analytic studies has yielded a two-factor structure (Lang, Greenwald, Bradley, & Hamm, 1993; Cuthbert, Schupp, Bradley, Birbaumer, & Lang, 2000). However, the startle blink reflex, a widely employed measure of the emotional response, has not been considered to date. We decided to include two parameters of the startle reflex (magnitude and latency) in order to explore further how this response fits into the two-factor model of emotion. We recorded the acoustic startle blink response, skin conductance response, heart rate, free viewing time, and picture valence and arousal ratings of 45 subjects while viewing 54 pictures from the International Affective Picture System (IAPS; 18 unpleasant, 18 neutral, and 18 pleasant). Factorizations of all measures gave a two-factor solution (valence and arousal) that accounted for 70% of the variance. Although some measurements, including heart rate change, did not behave as predicted, our results reinforce the two-dimension model of the emotion, and show that startle fits into the model.  相似文献

Studies of career development highlight the importance of finding a good "fit" between individual values, needs, and abilities and the experiences and rewards to be found in particular occupations. Rapid economic change and labor market turbulence make career choice and development life-long processes. Still, early careers are particularly unstable, as young workers move from "survival jobs" to "career jobs" in their quest for a good person-job fit. Little is known, however, about the psychological orientations and behaviors in the postadolescent period that foster longer term success in the world of work. The maintenance of high aspirations, crystallization of career goals, and intensive job search may be particularly important. Using multilevel latent class analysis applied to longitudinal data obtained from 1,010 youth surveyed by the ongoing Youth Development Study (YDS), we examine the interrelations of psychological orientations and behaviors indicative of agentic striving from age 18 to 31 years. In addition, we assess how these trajectories influence adaptation to declining labor market conditions during the severe economic recession that began in 2007. We find that those who maintain high aspiration and certainty over career goals were better insulated against unemployment between 2007 and 2009 (ages 33-35), even when educational and self-identified career attainments, adolescent achievement orientations, and social background variables indicative of advantage are controlled. They also had higher hourly wages in 2009. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献

The role of imagery, analogy, and instantiation in understanding proverbs was examined in the light of the Conceptual Base Theory (CBT). The CBT proposes that proverb comprehension involves four phases and that (a) after Problem Recognition, imagery is often used during the Literal Transformation Phase with the intention of constructing a figurative meaning but that imagery does not enter into this meaning; (b) figurative meaning is the solution to a four-part, a:b::c:d, analogy, which occurs during the Figurative Phase; (c) the Instantiation Phase can be entered only if a figurative meaning is constructed, but once instantiation occurs it serves to refine this meaning. A transfer paradigm was used to test these hypotheses. During acquisition, the subjects were presented proverbs and given rating tasks in connection with one of the following: pictures that illustrated the literal proverb information (picture groups), instructions to image the literal proverb information (imagery groups), or analogies involving literala andb terms drawn from the proverb andc andd terms that constituted an interpretation of the proverb (analogy group), concrete verbal instances that illustrated the proverbs' figurative meanings (instance group), or an analogy and an instance (analogy-instance group). During transfer, all subjects attempted to distinguish between novel sentences that were either positive or negative instances of the figurative meaning of the acquisition proverbs. The picture and imagery groups, which were assumed to have used imagery without the intention of constructing a figurative meaning, performed at chance. The analogy group performed above chance and on a par with the instance group subjects, who theoretically had constructed and solved an implicit analogy. The analogy-instance group showed superior performance. Discussion centered on the pattern of the results in relation to the CBT and on the role of imagery and analogy in understanding proverbs as opposed to metaphors.The authors wish to thank Suzanne Leake for help in designing the experiment, preparing materials, and running subjects.  相似文献

The impact of forced intra-task waiting periods was evaluated in a laboratory study designed in analogy to forced waiting periods in human-computer interaction. Each task consisted of two lines of grouped capital letters (so-called Sterzinger lines) that had to be processed individually, separated by the experimental waiting period. The final response to both lines was taken after removal of the second line. The experiment was conducted according to a within-subjects design with the order of the two factors "duration" (2 s vs. 8 s) and "variability of the waiting periods" (constant vs. variable) controlled. The dependent variables were performance indices, heart rate, electrodermal activity, and subjective measures of mood and physical complaints. The results showed effects of the duration of waiting periods for the performance and the physiological variables, and effects of the variability factor for the subjective variables. Shorter waiting periods were associated with higher scores of heart rate and skin resistance responses, variable waiting periods seemed to confuse the subjects more than constant ones. The results are discussed with respect to the effects of the two experimental factors. With respect to dialog structures in human-computer interaction, the results lead to the conclusion that response interference could be avoided by giving the user the possibility to immediately input problem solutions. Partial and preliminary inputs should be permanently kept visible during the whole task cycle by the software.  相似文献
