Factors affecting spontaneous alternation behavior (SAB) in animals, for example, age, gender and species studied; type of
apparatus and cues employed; and neuro-anatomical, neuro-chemical and motivational status of the organism, were reviewed.
Despite a myriad of experiments showing interesting main effects of such variables, little research has been performed assessing
the interactive affects of these factors on alternation behavior. For example, psychologists test rats in central nervous
system (CNS) lesion studies, whereas psychopharmacologists tend to assess SAB in mice. Most importantly, studies have not
been reported investigating the possible interactions among species, brain lesions and drugs. This is an unfortunate omission
since several important alternation models include propositions relating to cholinergic and/or serotonergic coding in the
hippocampus. Examination of behavioral studies revealed the primary cue for alternation among invertebrates to be body turn,
whereas vertebrates rely primarily on directional and odor cues. Reference to the seeking of stimulus change remains the most
compelling motivational account of why animals manifest this ubiquitious and reliable behavior pattern.

Two binary classification tasks were used to explore the associative structure of linear orders. In Experiment 1, college students classified English letters as targets or nontargets, the targets being consecutive letters of the alphabet. The time to reject nontargets was a decreasing function of the distance from the target set, suggesting response interference mediated by automatic associations from the target to the nontarget letters. The way in which this interference effect depended on the placement of the boundaries between the target and nontarget sets revealed the relative strengths of individual interletter associations. In Experiment 2, students were assigned novel linear orders composed of letterlike symbols and asked to classify pairs of symbols as being adjacent or nonadjacent in the assigned sequence. Reaction time was found to be a joint function of the distance between any pair of symbols and the relative positions of those symbols within the sequence. The effects of both distance and position decreased systematically over 6 days of practice with a particular order, beginning at a level typical of unfamiliar orders and converging on a level characteristic of familiar orders such as letters and digits. These results provide an empirical unification of two previously disparate sets of findings in the literature on linear orders, those concerning familiar and unfamiliar orders, and the systematic transition between the two patterns of results suggests the gradual integration of a new associative structure. 相似文献

Critical action—behaviours aimed at dismantling systems of oppression—must be examined within youths' racialized experiences and should incorporate cultural and sociohistorical factors. We considered an expansive list of items capturing youth behaviours to create a novel four-factor (service, community change, expression, and care) measure of critical action for Asian and Hispanic/Latinx youth. Multiple distinct profiles of critical action were identified within both racial-ethnic groups, and associations between the profiles and sociodemographic and contextual support variables were explored. Gender differences in the type of critical action were found in both racial-ethnic groups, pointing to the potential influence of gender roles on critical action among these populations. Differences in critical action patterns were also found between those born in the U.S. versus those born outside the U.S.; access to critical action may differ within racial-ethnic groups depending on birthplace and associated nuances in familial and cultural contexts. This paper demonstrated a need for attending to variation between and within groups in the study of critical action in order to effectively support racialized youth's coping within and resistance against systems of oppression. 相似文献

As the world has become increasingly concerned about environmental plastic pollution, private and public sectors remain devoted to creating effective green marketing campaigns on social media platforms. Drawing upon construal level theory and appraisal tendency theory, this research examines the interaction effect of green ad appeals and two distinct emotions—awe and guilt—on consumers' social media engagement and pro-environmental intentions. The findings from two experimental studies demonstrate that when individuals experience awe, desirability (vs. feasibility) message appeals generate stronger engagement in social media green campaigns. In contrast, it was found that when individuals experience guilt, feasibility (vs. desirability) message appeals enhance social media engagement and pro-environmental behaviors more effectively. This research offers novel theoretical contributions to the existing body of literature and provides practical insights by suggesting that awe and guilt act as moderators leading to greater consumer responses when used with matching social media messages promoting green campaigns. 相似文献

This research investigated the interplay between mood, disclosure language, and ad skepticism on consumers' recognition and evaluation of native advertising. During two online experiments, participants first received a mood manipulation and then read an article-style native advertisement. Results from both studies indicated that participants were more likely to recognize a native ad with an explicit rather than an implicit disclosure label, and a negative mood was more likely than a positive mood to drive participants to recognize the native ad. More importantly, participants in a positive mood evaluated a native ad with an implicit disclosure more favorably than an ad with an explicit disclosure. By contrast, participants in a negative mood responded more positively to a native ad with explicit disclosure compared to an ad with implicit disclosure. Study 2 demonstrated that the interaction between mood and disclosure language was further moderated by individuals' levels of ad skepticism. These results are believed to provide meaningful theoretical and practical implications to the field of native advertising and consumer behavior. 相似文献

Episodic memory decline is the prominent neuropsychological feature of typical Alzheimer's Disease (AD), for which current treatments have a limited clinical response. Recently, gamma entrainment therapy has been used as a non-invasive treatment in AD, providing evidence that it may have the potential to alleviate brain pathology and improve cognitive function in AD patients. At the same time, the precuneus (PC) has been recognized as a key area involved in AD related memory deficits and as a key node of the Default Mode Network. This study aimed to investigate the effectiveness of a 40 Hz Transcranial Magnetic Stimulation (TMS) intervention, delivered bilaterally to the precuneus for 10 days, in improving the patients' episodic memory performance. Secondary outcome variables investigated included general cognitive function, semantic and spatial memory, as well as attention and executive function. A concurrent multiple baseline design across five cases was employed. Four patients completed the study. Visual analysis combined with effect size indices were used to evaluate changes across phases. An increase in the average level of immediate recalled words was observed in three out of four patients. Effect size indices indicated significant improvement of attention skills in two patients. No treatment effect was observed for semantic and visual memory, or for executive function. An immediate treatment effect was observed in all patients' general cognitive function as assessed with the Alzheimer's Disease Assessment Scale (mean reduction of 5 points), which was maintained and improved further three months post-treatment. The neuropsychological evaluations indicated improved performance three months post-treatment in immediate and delayed recall, attention, phonological verbal fluency, anxiety, and neuropsychiatric symptoms. This study provides preliminary evidence for the efficacy of a novel non-pharmacological treatment using gamma-band TMS in addressing cognitive dysfunction in AD. 相似文献

Abstract— Two experiments investigated the role of spatial organisation in the discrimination and generalization of complex visual stimuli by pigeons. In Experiment 1, after pigeons had been trained to discriminate line drawings of four objects, they were tested with novel pictures in which the same component parts of the objects were spatially rearranged. The spatially scrambled pictures led to a dramatic drop in recognition accuracy, hut responding remained above chance. In Experiment 2, pigeons reached a high level of discriminative performance when required to choose among four different spatial arrangements of the same object parts. These results confirm Cerella's (1980) conclusion that pigeons discriminate the component parts of complex visual stimuli, but. unless it is assumed that the scrambling deleted or created emergent features, the results disconfirm his conclusion that spatial organization plays no role in pigeons' picture perception. 相似文献

Two studies examined the consequences of turnover, by investigating factors affecting the job satisfaction of people who remain (i. e., stayers) in response to a coworker (i. e., leaver) who departed for a better job. Consistent with Tesser and Campbell's (1983) self-esteem maintenance model, three factors were found to influence the job satisfaction level of stayers: (a) the extent to which they compared their job situation to the leaver's new one, which was negatively related to stayers’ level of satisfaction, (b) the relevance of the leaver to the stayer for social comparison purposes, which was negatively related to the stayers’ level of satisfaction, and (c) the stayers’ trait self-esteem, which was positively related to the stayers’ level of job satisfaction. Theoretical implications, limitations, and future research directions are discussed. 相似文献

Summary In this study the role of perceptual and motor factors on the motor organization (integrated versus parallel) adopted by musically skilled and unskilled subjects in a polyrhythmic tapping task was investigated. Subjects tapped a 3:2 polyrhythm to match the timing of two isochronous tone trains, one tone train for each hand. Perceptual factors were examined by the manipulation of the frequency difference between the tone trains to produce either an integrated or a streamed percept. Motor factors were examined by comparison of performance on two versions of the 3:2 polyrhythm. In one (simultaneous) version, each cycle of the polyrhythm began with a simultaneous left- and right-hand tap. In the other (shifted) version a 100-ms interval was introduced between the initial left and right taps in each cycle. Examination of the pattern of variances and covariances among intertap intervals suggested that most of the subjects in this study adopted an integrated motor organization that involved interleaving the timing of the two hands. Further analysis revealed that a serial chained model described the pattern of covariances best for the simultaneous pattern, whereas a hierarchical organization described the pattern of covariances for the shifted pattern best. The finding that performance was more accurate with integrated tones than with streamed tones provides some support for a perceptual-motor facilitation hypothesis. 相似文献

Two experiments are reported, which examined the relative contributions of preload (resting force level), change of force, and the time taken to achieve the force in determining isometric force variability. The findings showed that change of force is the strongest determiner of peak force variability but that preload and time to peak force have smaller though systematic effects. A formula that predicts peak force variability is proposed, with preload as an additive effect to the ratio between the change of force level and the square root of time to peak force. These findings confirm that these three impulse variables are significant in predicting force variability and that the impact of rate of force on peak force variability is nonlinear. 相似文献
