The potential for communication through the kinesthetic aspect of the tactual sense was examined in a series of experiments employing Morse code signals. Experienced and inexperienced Morse code operators were trained to identify Morse code signals that were delivered as sequences of motional stimulation through up-down displacements (roughly 10 mm) of the fingertip. Performance on this task was compared with that obtained for both vibrotactile and acoustic presentation of Morse code using a 200-Hz tone delivered either to the fingertip through a minishaker or diotically to the two ears under headphones. For all three modalities, the ability to receive Morse code was examined as a function of presentation rate for tasks including identification of single letters, random three-letter sequences, common words, and sentences. Equivalent word-rate measures (i.e., product of percent correct scores and stimulus presentation rate) were nearly twice as high for auditory presentation as for vibrotactile stimulation, which in turn was about 1.3 times that for motional stimulation. The experienced subjects outperformed the inexperienced subjects by amounts that increased with task complexity. For example, the former were able to receive sentences at 18 words/min with motional stimulation, whereas the latter, following 75 h of training, were unable to perform this task. The present results and those of other research with tactual communication systems are compared, particularly regarding estimates of information-transfer rates. 相似文献

Despite frequent mention, we know relatively little about the effect of ambient environmental factors on consumer behavior. This paper discusses one important aspect of the environment, ambient scent. Based on research from several disciplines, a model describing the effect of ambient scent on consumers is propossed. Ambient scent is portrayed as an environmental cue that is compared with scent preferences to influence affective responses and ultimately approach-avoidance reactions. Moderators of these presumed relationships are also described. Suggestions for empirical research are provided and implications for marketing management are presented. 相似文献

In the context of evaluative conditioning, the effects of additional presentations of the unconditioned stimulus (US) prior to conditioning (US preexposure) or after conditioning (US postexposure) were examined using between- and within-subjects control conditions. Two experiments that differed with respect to the nationality of the subjects were conducted. In both experiments, US-alone presentations reduced the magnitude of the evaluative response. The US pre- and postexposure effects were observed in subjects classified as aware as well as in subjects classified as unaware of the experimental contingencies. Another finding is that the evaluative conditioning procedure described by Martin and Levey (1978; Levey & Martin, 1975) resulted in reliable conditioning effects also in an American sample, thus extending the scope of that special evaluative conditioning paradigm. The findings are discussed in the context of recent models of classical and evaluative conditioning. Especially, the unexpected US postexposure effect gives rise to speculations concerning the learning process underlying evaluative conditioning. 相似文献

Relationships among maternal characteristics, ratings of child behavior, and observed mother-child interactions were examined in a sample of 40 4- to 12-year-old children with externalizing disorders. Mothers and children were observed in a task interaction and mothers provided self-reports of depressed mood, parenting self-esteem, marital satisfaction, social support, and life stress. Child behavior was rated by both mothers and teachers. Several significant correlations were found among observed mother and child behaviors and among maternal self-report measures. However, few significant relationships were found between maternal characteristics and observed mother or child behavior. Although life stress predicted increased child negativity, maternal depressed mood was related to more appropriate child behavior. Mother and teacher ratings of child behavior demonstrated few significant relationships with other measures. These results suggest that, in samples comprised primarily of children with attention deficit disorder from socially advantaged families, few relationships exist between maternal characteristics, parenting behavior, and child behavior.This study was part of a doctoral dissertation conducted by the first author at Florida State University, under the direction of the second author, and supported by the Social Sciences and Humanities Research Council of Canada. Portions of the data also appear in a chapter by Johnston titled A behavioral-family systems approach to assessment: Maternal characteristics associated with externalizing behavior in children. In R. Prinz (Ed.),Behavioral assessment of children and families (Vol. 4, pp. 163–189). Greenwich, CT: JAI Press. The authors express appreciation to Alan Lang, Barbara Licht, and Richard Tate, for their thoughtful comments. We are grateful to Beverley Atkeson and a dedicated group of coders and to Dr. C. E. Cunningham and the staff of the Chedoke Child and Family Center for their support. Finally, our thanks to the families who participated. 相似文献

This study was designed to test the hypothesis that systematic variations in listener behavior can have an important influence on both speaker behavior and communicative success among children. In particular, we investigated the idea that systematic variations in listener behavior might have not only within-trial effects on the adequacy of speakers' messages and the accuracy of communication among children, but also cumulative effects on speakers' initial messages across trials. Effects of stimulus complexity were also examined. Pairs of 7- and 9-year-old children participated in a referential communication game, with the younger child serving as speaker and the older one as listener. Half of the listeners were given a plan for effective listening which emphasized the importance of asking questions if the speakers' messages were ambiguous. Replicating earlier findings, the plan manipulation was successful in encouraging listeners to ask questions when necessary. The major result was that listener questions not only had the expected trial-by-trial effect on message adequacy and communicative accuracy, but also showed a cumulative effect on speaker performance. When exposed to systematic listener feedback, speakers improved their initial messages over trials. Stimulus complexity was not a major determinant of performances. These findings suggest that provision of systematic listener feedback may be an effective method for teaching speaker skills to young children. 相似文献

The concept that the child is predisposed to the fear of infanticide, and that that fear may be the central cause of his psychological problems and the primary motive force of his defense, allows us to view the defensive process from a different perspective than that offered by Freud's nuclear theory. Children's fantasies make it apparent that the idealization of their parents' image, and the devaluation of their own, constitute their basic defense against their fear. 相似文献

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play. 相似文献

Research suggests that an overgeneral autobiographical memory style (i.e., retrieval of general memories when instructed to retrieve a specific episodic memory) represents a vulnerability marker for depression. Although adolescence is a period of high risk for the emergence of depression, little research has investigated the associations among overgeneral memory, psychopathology, and risk factors longitudinally in a community sample in this age group. We, therefore, investigated overgeneral memory, psychopathology (depression and anxiety), and rumination (an established risk factor for psychopathology) longitudinally in 269 typically-developing youth (125 females, 144 males) across 3 annual assessment points. We sought to determine whether 1) overgeneral memory would predict psychopathology across the entire sample, and 2) whether associations would vary as a function of longitudinal rumination growth. Across the entire sample, overgeneral memory did not predict psychopathology. For youth who reported elevated, and increasing, patterns of rumination over time, transient relationships between overgeneral memory and subsequent increases in anxiety were found. We conclude that overgeneral memory may represent a vulnerability marker for adverse psychological outcomes only for youth at risk for psychopathology. 相似文献
