The goal of the current study was to examine the predictive relationships among a set of cognitive-motivational variables
that have been found in previous studies to support academic achievement. Student perception of a classroom’s achievement
goal structure (classroom mastery, classroom performance-approach, classroom performance-avoidance) was used as the primary
set of predictor variables, while student perceptions of belonging and subject matter instrumentality were used as dependent
variables. There were 227 participants in the current study each of whom were enrolled in a rural high school in the Midwestern
United States. Results indicated that the classroom level goal orientation was, in fact, predictive of belonging and perceived
instrumentality. Specifically, classroom mastery goals and classroom performance-approach goals were found to positively relate
to both belonging and perceived instrumentality. Implications of the aforementioned relationships are discussed. 相似文献

It has been speculated that cage mesh exerts a shaping influence on reaching behavior by captive apes, which is then misconstrued
as pointing by human observers. Although this notion is clearly falsified by the pointing of captive language-trained apes—who
point in the absence of intervening cage mesh—nevertheless, the degree to which cage mesh might influence pointing hand shapes
by captive great apes in other housing environments remains relatively unexplored. We examined 259 pointing gestures displayed
in archival footage from over 18 h of observation by three nonlanguage-trained chimpanzees housed at a biomedical research
center. We coded points in relation to how close to the boundaries of the diamond-shaped cage mesh their points were displayed.
We found that points with the whole hand were significantly more likely to be displayed away from the mesh boundaries, relative
to points with the index finger or other single-digit points. However, points of each hand shape were displayed at each location,
demonstrating that these physical parameters do not fully account for the number of fingers extended while pointing by chimpanzees. 相似文献

Advances in bioacoustics allow us to study the perceptual and functional relevance of individual acoustic parameters. Here, we use re-synthesised male koala bellows and a habituation-dishabituation paradigm to test the hypothesis that male koalas are sensitive to shifts in formant frequencies corresponding to the natural variation in body size between a large and small adult male. We found that males habituated to bellows, in which the formants had been shifted to simulate a large or small male displayed a significant increase in behavioural response (dishabituation) when they were presented with bellows simulating the alternate size variant. The rehabituation control, in which the behavioural response levels returned to that of the last playbacks of the habituation phase, indicates that this was not a chance increase in response levels. Our results provide clear evidence that male koalas perceive and attend to size-related formant information in their own species-specific vocalisations and suggest that formant perception is a widespread ability shared by marsupials and placental mammals, and perhaps by vertebrates more widely. 相似文献

We utilize a novel advertising context—commercials seen in a simulated movie theater setting while ambient scent is emitted into the atmosphere—to explore the effects of multisensory cues on brand evaluation and advertising recall. Although both pictorial and olfactory cues enhance brand evaluations and ad recall overall, we find that olfactory (vs pictorial) cues generate more positive feelings toward the brand and enhance recall to a greater extent. We also find that, after a long time delay, re‐experiencing the scent activates pictures' ability to facilitate recall. Theoretical and managerial implications are discussed.

Humans have the ability to mentally time travel through past, present, and future. But can a disruption in emotion characteristic of emotional disorders cause this ability to unwind, leaving people "stuck" in the present emotional moment? Two studies are presented that examine emotional time-perspective in a disorder (mania) characterized by present-oriented tendencies, including impulsivity and emotion dysregulation. In Study 1, associations were reported between mania proneness and emotion time-perspective (n = 509), and Study 2 compared emotion time-perspective between individuals with a clinical history of mania (n = 32), and controls (n = 30). We show that mania is associated with increased present and decreased future focus. These findings suggest that emotional disorders can be understood, at least in part, by examining how people understand and use time to guide their behavior and feelings. 相似文献

The words used to describe emotions can provide insight into the basic processes that contribute to emotional experience. We propose that emotions arise partly from interacting evaluations of one's current affective state, previous affective state, predictions for how these may change in the future, and the experienced outcomes following these predictions. These states can be represented and inferred from neural systems that encode shifts in outcomes and make predictions. In two studies, we demonstrate that emotion labels are reliably differentiated from one another using only simple cues about these affective trajectories through time. For example, when a worse-than-expected outcome follows the prediction that something good will happen, that situation is labeled as causing anger, whereas when a worse-than-expected outcome follows the prediction that something bad will happen, that situation is labeled as causing sadness. Emotion categories are more differentiated when participants are required to think categorically than when participants have the option to consider multiple emotions and degrees of emotions. This work indicates that information about affective movement through time and changes in affective trajectory may be a fundamental aspect of emotion categories. Future studies of emotion must account for the dynamic way that we absorb and process information. 相似文献

Recent proponents of the ??theory theory?? of mind often trace its roots back to Wilfrid Sellars?? famous ??myth of Jones?? in his 1956 article, ??Empiricism and the Philosophy of Mind??. Sellars developed an account of the intersubjective basis of our knowledge of the inner mental states of both self and others, an account which included the claim that such knowledge is in some sense theoretical knowledge. This paper examines the nature of this claim in Sellars?? original account and its relationship to more recent debates concerning ??theory of mind??, in particular the theory theory. A close look reveals that Sellars?? original view embodied several distinctions that would enable more recent theory theorists to accommodate certain phenomenological objections that have been raised against that outlook. At the heart of the philosophical issue is an overlooked complexity involved in Sellars?? account of the ??theory/observation?? distinction, involving a conception of the distinction that is both independently plausible and a key to the issue in dispute. 相似文献

Mary Gentile’s Giving Voice to Values presents an approach to ethics training based on the idea that most people would like to provide input in times of ethical conflict using their own values. She maintains that people recognize the lapses in organizational ethical judgment and behavior, but they do not have the courage to step up and voice their values to prevent the misconduct. Gentile has developed a successful initiative and following based on encouraging students and employees to learn how to engage in communication or action to express their values within an organization’s formal and informal value system. The purpose of this analysis is to examine the Giving Voice to Values approach to empowering the individual to take action to deal with lapses in organizational ethics. We examine the role of Giving Voice to Values in business ethics education, considerations for implementing GVV, and recommendations for business educators and corporate ethics officers. We conclude that while GVV is an effective tool, it is not a comprehensive or holistic approach to ethics education and organizational ethics programs. 相似文献

In this article, I present a case for a kind of existential theology which would be philosophical and metaphysical, though not broadly Platonic and classical, and biblical though not illogical. What I present will be an attempt to clarify and justify what I call ??existential hayatological theism??. In so doing I will draw on insights from what Edmond La B Cherbonnier and Claude Tresmontant designated as ??biblical philosophy?? and ??biblical metaphysics?? as well as from the neo-classical philosophies of Charles Hartshorne and Alfred North Whitehead, especially that of Whitehead. 相似文献
