Striking changes in sensitivity to tonality across the pitch range are reported. Participants were presented a key-defining context (do-mi-do-sol) followed by one of the 12 chromatic tones of the octave, and rated the goodness of fit of the probe tone to the context. The set of ratings, called the probe-tone profile, was compared to an established standardised profile for the Western tonal hierarchy. The presentation of context and probe tones at low and high pitch registers resulted in significantly reduced sensitivity to tonality. Sensitivity was especially poor for presentations in the lowest octaves where inharmonicity levels were substantially above the threshold for detection. We propose that sensitivity to tonality may be influenced by pitch salience (or a co-varying factor such as exposure to pitch distributional information) as well as suprathreshold inharmonicity. 相似文献

Deconstructing executive deficits among persons with autism: implications for cognitive neuroscience
Individuals with autism demonstrate impairments on measures of executive function (EF) relative to typically developing comparison participants. EF is comprised of several processes including inhibition, working memory and set shifting that develop throughout the lifespan. Impairments in EF may appear early in development and persist, or may represent a more transient delay which resolves with time. Given the unevenness of the cognitive profile of persons with autism, understanding the development of EF poses methodological challenges. These issues include those related to matching measures and the choice of comparison participants to which the performance of persons with autism will be compared. In the current review, we attempt to break down the processes of inhibition, working memory and set shifting among persons with autism. We propose to do this within a developmental perspective that highlights how matching measures and comparison participants can affect the interpretation of research findings. 相似文献

Wentura and Frings (2005) reported evidence of subliminal categorical priming on a lexical decision task, using a new method
of visual masking in which the prime string consisted of the prime word flanked by random consonants and random letter masks
alternated with the prime string on successive refresh cycles. We investigated associative and repetition priming on lexical
decision, using the same method of visual masking. Three experiments failed to show any evidence of associative priming, (1)
when the prime string was fixed at 10 characters (three to six flanking letters) and (2) when the number of flanking letters
were reduced or absent. In all cases, prime detection was at chance level. Strong associative priming was observed with visible
unmasked primes, but the addition of flanking letters restricted priming even though prime detection was still high. With
repetition priming, no priming effects were found with the repeated masked technique, and prime detection was poor but just
above chance levels. We conclude that with repeated masked primes, there is effective visual masking but that associative
priming and repetition priming do not occur with experiment-unique prime-target pairs. Explanations for this apparent discrepancy
across priming paradigms are discussed. The priming stimuli and prime-target pairs used in this study may be downloaded as

The objective of this research is to show that, under usual conditions of interaction between an agent of health and of its public intervention, the individuals produce a “pro-health” speech which can lead astray this agent, concerning the representation which they have of alcohol. Students, producing verbal associations about this object, were confronted either with an agent of health or with a student, and were speaking either for themselves or as the students would do in general. The results show that the individuals, placed in front of an agent of health and directly implied in the beliefs that they express, tend to adopt the speech wished by this agent. However, this manifest adhesion only appears to be circumstantial, insofar as the speech of the individuals is different when they are expressed vis-a-vis a member of its group and in the name of this one. The implications of these results with regard to the interventions of prevention are discussed. 相似文献

Spontaneous preferences towards possible prey have been little investigated using targets in motion. Preferences of domestic
chicks (Gallus gallus) to peck at video-images of stimuli representing live insects moving along their longer body axis (i.e. “forwards”) or along
the shorter body axis (i.e. “sideways”) were investigated. Chicks presented with both types of stimulus displayed a significant
preference for pecking at stimuli moving sideways. This preference was already present on day 1 post-hatching, and it strengthened
on day 6 for those chicks that had experienced pecking at live insects. Head angles used to fixate the stimuli prior to pecking
were also analysed and were consistent (i.e. 30°–35° and 60°–65°) with those reported for fixation of non-edible targets (larger
stimuli at a distance). In a first control experiment the same video-presented stimuli were used but the insect’s legs were
removed to reduce flickering. In a second control experiment, paper-printed images of the whole insect were used. In both
cases, the sideways direction of movement was clearly preferred. Overall, our data show that chicks have a spontaneous preference
to peck at video-images resembling live insects moving along their shorter body axis. Sideways movement may constitute a crucial
signal attracting chicks’ attention and enhancing predatory responses possibly because of stronger stimulation of motion detectors. 相似文献

The ability to recognize three-dimensional objects from two-dimensional (2-D) displays was investigated in domestic chicks,
focusing on the role of the object’s motion. In Experiment 1 newly hatched chicks, imprinted on a three-dimensional (3-D)
object, were allowed to choose between the shadows of the familiar object and of an object never seen before. In Experiments
2 and 3 random-dot displays were used to produce the perception of a solid shape only when set in motion. Overall, the results
showed that domestic chicks were able to recognize familiar shapes from 2-D motion stimuli. It is likely that similar general
mechanisms underlying the perception of structure-from-motion and the extraction of 3-D information are shared by humans and
animals. The present data shows that they occur similarly in birds as known for mammals, two separate vertebrate classes;
this possibly indicates a common phylogenetic origin of these processes. 相似文献

The analysis of time is vitiated very often by circularity: several disciplines, such as psychology, linguistics, and neurosciences,
analyze time by using concepts or terms which already contain in themselves, or are based, on the experience and notion of
time (as when, for example, time is defined as “duration”, or when our ability to estimate durations is explained by resorting
to the notion of an internal clock). Some detailed examples of circularity in the analysis of time are given here and examined.
A way out of circularity is then given: it is represented by the proposal of attentional semantics (AS) of considering words
and their meanings in terms of the aim they serve, and the means and processes developed and implemented in order to achieve
that aim. According to AS, the main aim of words is that of indicating to, and eliciting in, the listener or reader a specific
conscious experience: namely, the conscious experience referred to by their meanings. Words achieve their main aim by conveying
the condensed instructions on the attentional operations one has to perform if one wants to consciously experience what is
expressed through and by them. By describing the conscious experiences elicited by words in terms of the attentional operations
that are responsible for the production of such conscious experiences, AS offers an a-linguistic counterpart to language,
and therefore an effective way out of circularity. Following in footsteps of Mach (Contributions to the analysis of the sensations,
1890), but slightly revising his hypothesis, AS defines time-sensation as the perception of the effort made, or alternatively
the nervous energy expended, by the organ of attention when performing a “temporal activity” (for instance, estimating duration),
that is, when one’s own attention is focused in a continuous and incremental way on the conscious product of the (“non-temporal”)
activity performed by means of another portion of one’s attention.

Reasonning in naive set theory (with unlimited comprehension), we derive a paradox (a formal contradiction) which can be seen
as a variant of the Burali-Forti paradox.
