Two experiments are reported that examine the effects of caffeine consumption on attitude change by using different secondary tasks to manipulate message processing. The first experiment employed an orientating task whilst the second experiment employed a distracter task. In both experiments participants consumed an orange‐juice drink that either contained caffeine (3.5 mg/kg body weight) or did not contain caffeine (placebo) prior to reading a counter‐attitudinal communication. The results across both experiments were similar. When message processing was reduced or under high distraction, there was no attitude change irrespective of caffeine consumption. However, when message processing was enhanced or under low distraction, there was greater attitude change in the caffeine vs. placebo conditions. Furthermore, attitudes formed after caffeine consumption resisted counter‐persuasion (Experiment 1) and led to indirect attitude change (Experiment 2). The extent that participants engaged in message‐congruent thinking mediated the amount of attitude change. These results provide evidence that moderate amounts of caffeine increase systematic processing of the arguments in the message resulting in greater agreement.

A cross-cultural comparison between U.S. and Hong Kong preschoolers examined factors responsible for young children’s analogical reasoning errors. On a scene analogy task, both groups had adequate prerequisite knowledge of the key relations, were the same age, and showed similar baseline performance, yet Chinese children outperformed U.S. children on more relationally complex problems. Children from both groups were highly susceptible to choosing a perceptual or semantic distractor during reasoning when one was present. Taken together, these similarities and differences suggest that (a) cultural differences can facilitate better knowledge representations by allowing more efficient processing of relationally complex problems and (b) inhibitory control is an important factor in explaining the development of children’s analogical reasoning. 相似文献

Over the past several decades, significant advances have been made in our understanding of the basic stages and mechanisms
of mammalian brain development. Studies elucidating the neurobiology of brain development span the levels of neural organization
from the macroanatomic, to the cellular, to the molecular. Together this large body of work provides a picture of brain development
as the product of a complex series of dynamic and adaptive processes operating within a highly constrained, genetically organized
but constantly changing context. The view of brain development that has emerged from the developmental neurobiology literature
presents both challenges and opportunities to psychologists seeking to understand the fundamental processes that underlie
social and cognitive development, and the neural systems that mediate them. This chapter is intended to provide an overview
of some very basic principles of brain development, drawn from contemporary developmental neurobiology, that may be of use
to investigators from a wide range of disciplines. 相似文献

The author indexes of 15 introductory psychology textbooks were surveyed to identify the authorities cited most frequently. The five names cited most often in descending order were Freud, Bandura, Skinner, Piaget, and James. Differences from earlier comparable citation studies are discussed. 相似文献

This study assesses the criterion-related relevance or concurrent validity of Physical Educators' Attitude Toward Individuals with Disabilities III survey, developed in 1993 by Rizzo. The criterion measure was the Learning Handicapped Inventory, developed in 1982 by Jansma and Shultz, because it, like the former, has validity and reliability in assessing attitudes of physical educators toward teaching students with disabilities. Participants were 179 physical education majors attending a major midwestern university, 94 (53%) women and 85 (47%) men whose average age was 20.7 yr. (SD = 2.5 yr.). Both surveys were administered in one sitting, and the correlation of .88 indicates strong concurrent validity. 相似文献

Two procedures were used to explore the effects of semantic and grammatical gender on the recognition and processing of Bulgarian nouns, in relation to other factors that are known to affect lexical access. This study in a three-gender language was modeled on previous work in Italian, a two-gender language (Bates, Devescovi, Pizzamiglio, D'Amico, & Hernandez, 1995). Words were presented auditorily in randomized lists in two tasks: (1) repeat the word as quickly as possible and (2) determine the grammatical gender of the noun as soon as possible and indicate the decision by pressing a button. Reaction times in both tasks were influenced by phonological factors, word frequency, and irregularity of gender marking, but semantic and grammatical gender affected only gender monitoring. The significant contribution of semantic gender to processing in Bulgarian contrasts with previous findings for Italian. Also, we obtained an interaction between sex of the subject and noun gender, reflecting a bias toward one's own grammatical gender "counterpart" (especially for females). Reanalysis of the prior study in Italian showed a similar interaction but confirmed no effects of the semantic gender of the noun, suggesting that these two natural gender effects can dissociate. Possible reasons for cross-linguistic differences are discussed, with implications for comparative studies of gender and lexical access. 相似文献

Differential reinforcement of alternative behavior (DRA) may result in rates of reinforcement that are impractical for caregivers to implement; therefore, recent research has examined methods for thinning reinforcer delivery during DRA. In this study, reinforcer delivery was thinned during DRA by restricting access to the participant's alternative response materials. 相似文献

Three studies examined the relation between context dependence in information processing and behavioral mimicry. In Experiment 1, a field-dependent cognitive style was related to a greater tendency to mimic a target's behavior. In Experiment 2 context dependence was experimentally manipulated, and results showed more mimicry in the session where a context-dependent processing style was induced compared with the session where a context-independent processing style was induced. Experiment 3 provided evidence for bidirectionality in the relation between context dependence and mimicry. Specifically, participants whose posture and behavior had been unobtrusively mimicked by an experimenter subsequently processed information in a more context-dependent manner than did nonmimicked participants. Taken together, these results illustrate the interplay between basic cognitive and behavioral processes. 相似文献
