Compare
and contrast the ` direct ` perception theory of Gibson with the
`constructivist` perception theory of Gregory . Which provides a
better account of human perception?
Sensation
involves physical stimulation of the sense organs, while perception
is the organisation and interpretation of incoming sensory information. The Gestalt theorists first identified many of the principles that dominate in human visual perception. As Dowell (1995) has observed : “To perceive seems effortless. To understand perception is nevertheless a great challenge ” (cited in Gross, 2005, pp 244). This essay will look at
Gregory’s theory and Gibson’s theory of visual perception whether
one or the other offers a better explanation of human visual
perception.
According
to top-down perceptual processing theorists, perception is the end result of an indirect process that involves making inferences about
the world based on knowledge and expectations . An example of this
process is Gregory’s (1980) constructivist theory. He suggests that
to avoid sensory overload , we need to select from the information

Philosophy Aristotle - four causes or better "becauses" because they are the 4 ways in which we use the word "because" or answer the question "why?" 1. Material cause: - what it is made of - why is the bridge strong? because made of steel 2. Formal cause: - what form, definition or property it has - why is this salt? because made of sodium and chloride 3. Efficient cause: - what initiated the change or movement - why did the baseball move? because someone hit it 4. Final cause: - what end or goal does it have? - why does he walk? because he wants to be healthy - also nature operates in terms of final causes - things don't happen spontaneously, every action that nature takes is for the sake of something, everything has a purpose - where a series has a completion, all th
PSYCHOLOGY PART 1: CORE Biological level of analysis Outline principles that define the biological level of analysis. 1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning potential to provide survival advantages. This evolutionary hypothesis was tested in 37 cultures by sending out questioners. 2) Twin studies (type of correlational stud
Psychology Gleitman Blood flow in the brain during different activities: the rate of blood flow is measured by special radiation counters that are placed at various points of the skull and that monitor radiation from mildly radioactive gas injected into the bloodstream. Blood flow pattern depends on what the patient does ( different pattern is found when person is reading aloud, yet another when he watches a moving light and so on). Ambiguous sights and sounds: The way ambiguous figures are perceived often depends on what we have seen just before. For example, if we are first shown an unambiguous figure of a rat, the ambiguous picture will be seen as a rat. If we are first exposed to an unambiguous face, we see the ambiguous figure as a face. What holds for visual patterns also holds for language. Many utterances are ambiguous. If presented out of context, they can be undestrood in several different ways. For example, ,,The mayor ordered the police to stop drink
1 The Medium Is the Message In a culture like ours, long accustomed to splitting and dividing all things as a means of control, it is sometimes a bit of a shock to be reminded that, in operational and practical fact,, the medium is the message. This is merely to say that the personal and social consequences of any medium-that is, of any extension of ourselves-result from the new scale that is introduced into our affairs by each extension of ourselves, or by any new technology. Thus, with automation, for example, the new patterns of human association tend to eliminate jobs, it is true. That is the negative result. Positively, automation creates roles for people, which is to say depth of involvement in their work and human association that our preceding mechanical technology had destroyed. Many people would be disposed to say that it was not the machine, but what one did with the machine, that was its meaning or message. In terms of the ways in which the machine altered our relations to
Kujutlus linnast Kevin Lynch Peatükk 1: Kujutlus keskkonnast Esimene peatükk selgitab linna mõistet ja tutvustab linnakeskkonna kogemisega seotud mõisteid nagu loetavus, struktuur ja identiteet, kujuteldavus ning kujutluse loomist, samuti tutvustab ülejäänud raamatut. Linn on suuremõõtmeline konstruktsioon ruumis, mida on võimalik vaadelda vaid aja möödudes. Ehkki see on ajas võrdlemisi stabiilne, on see samal ajal igavesti muutuv detailides. Linna muutumise üle on võimalik omada vaid osalist kontrolli ja on oluline arvestada, et sel ei ole konkreetset lõpptulemust. Samuti on oluline mõista et linnapildis on liikuvatel objektidel, nagu inimesed ning nende tegevus, sama oluline tähtsus kui liikumatutel. Keeruline on linnakeskkonna puhul saavutada ühtselt head kvaliteeti ning ehkki enamusele linna elanikest on selge, millises inetus, räpases, kaootilise
Sheep senses and social cognition Sheep generally are held in low regard as far as cognition and social skills are concerned. However there is now interesting evidence from studies of their behaviour and brain function that they have highly sophisticated social and emotional recognition skills using faces, voices and smell. They are able to recognize and remember many diferent sheep and humans for several years or more and appear to have some capacity for forming mental images of the faces of absent individuals. The precence of such social cognition abilities in this species means that we must pay careful attention to welfare factors such as the composition and stability of their social environment as well as the nature of our own interactions with them. To many humans sheep are regarded as being as close to an automaton and amindless animal species as can be imagined and any serious consideration of their cognitive, social and general mental faculties deemed futile. I can give examp

Cultural differences of experiencing hallucinations Introduction In this literature review I am going to examine the cultural differences of hallucinations. I chose this topic because I had briefly heard that such differences exist but had not researched further so this was a perfect opportunity to satisfy my curiosity. I had heard that in India, hallucinations are mostly experienced as benign or even helpful like the embodiment of a wise ancestor, whereas in western culture hallucinations are mainly experienced as malicious and threatening. This seems interesting because malicious hallucinations seem to me to be one of the worst symptoms of schizophrenia and if there is a possibility of making hallucinations easier to cope with without the use of antipsychotics then that seems like a possibility worth investigating. Antipsychotics are necessary for many patients but they also have many side effects and using them less would be preferable. Most of the literature focuses
