Question

Some harmless flies resemble bees and wasps. What is this mechanism called? Evaluate its importance as a defense mechanism.

Answer 1

may refer to:

* Mechanism (biology), explaining how a feature is created.
* Mechanism (philosophy), a theory that all natural phenomena can be explained by physical causes
* Mechanism (horology), a piece of a time-keeping device
* Mechanism (sociology), a set of rules designed to bring about a certain outcome
* Mechanism (technology), a device of which a mechanical joint is used

In psychoanalytic theory, defence mechanisms are unconscious resources used by the ego to reduce conflict between the id and superego and thereby anxiety. For that reason they are more accurately referred to as ego defence mechanisms. They can thus be categorized as occurring due to the following scenarios:

* When the id impulses are in conflict with each other;
* When the id impulses conflict with superego values and beliefs;
* When an external threat is posed to the ego.

The term "defence mechanism" is often thought to refer to a definitive singular term for personality traits which arise due to loss or traumatic experiences, but more accurately refers to several types of reactions which were identified during and after daughter Anna Freud's time.

The list of particular defence mechanisms is huge and there is no theoretical consensus on the amount of defence mechanisms. It has been attempted to classify defence mechanisms according to some of their properties (i.e. underlying mechanisms, similarities or connections with personality). Different theorists have different categorizations and conceptualizations of defence mechanisms. Large reviews of theories of defence mechanisms are available from Paulhus, Fridhandler and Hayes (1997)[1] and Cramer (1991)[2]. Also Journal of Personality (1998)[3] has a special issue on defence mechanisms.

O.F. Kernberg's view of borderline defence mechanisms

Otto Kernberg (1967) has developed a theory of borderline personality organization (which one consequence may be borderline personality disorder). His theory is based on ego psychological object relations theory. Borderline personality organization develops when the child cannot integrate positive and negative mental objects together. Kernberg views the use of primitive defence mechanisms central to this personality organization. Primitive psychological defences are projection, denial, dissociation or splitting, and they are called borderline defence mechanisms. Also devaluation and projective identification are seen as borderline defences. [4]

G.E. Vaillant's hierarchy of defence mechanisms

In George Vaillant's (1977) categorization defences form a continuum regarding to their psychoanalytical developmental level [5]. Levels are:

* Level I - psychotic defences (i.e. psychotic denial, delusional projection)
* Level II - immature defences (i.e. fantasy, projection, passive aggression, acting out)
* Level III - neurotic defences (i.e. intellectualization, reaction formation, dissociation, displacement, repression)
* Level IV - mature defences (i.e. humor, sublimation, suppression, altruism, anticipation)

R. Plutchik's psychoevolutionary theory of emotions and defence mechanisms

Robert Plutchik's (1979) theory views defences as derivatives of basic emotions. Defence mechanisms in his theory are (in order of placement in circumplex model): reaction formation, denial, repression, regression, compensation, projection, displacement, intellectualization. [6]

Classification in diagnostic and statistical manual of mental disorders (DSM-IV)

Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) published by American Psychiatric Association (1994) includes tentative diagnostic axis for defence mechanisms [7]. This classification is largely based on Vaillant's hierarchical view of defences, but has some modifications. Levels of defence are:

* Defensive disregulation (i.e. delusional projection and psychotic denial)
* Action Level (i.e. passive aggression, acting out)
* Disavowal or image-distorting (ie. projection, fantasy)
* Compromise formation level (i.e. dissociation, displacement)
* High adaptive (i.e. altruism, sublimation)

Answer 2

This is called mimicry. It's a structural adaptation for survival.

It's a good defense mechanism because it allows them to survive. Animals that have had a bad experience with a look-alike bee or wasp will leave these harmless flies alone.

Answer 3

The defense is called mimicry.

Do you have access to an encyclopedia? Encarta or a print encyclopedia perhaps? Is this term discussed in your textbook? Read your textbook or get a quick overview of the term by reading an encyclopedia article. That should help you evaluate it's importance as a defense mechanism.

Answer 4

Mimicry, one good example is the coral snake and one variety of milk snake. When you first see one, they look exactly alike, except the colors are in a different order or just slightly different. But the coral snake is deadly and the mild snake is harmless to humans and in fact kills a lot of vermin, including poisonous snakes.

I really don't know what a biologist would say as to mimicry's effectiveness sorry. A picture comparing the two is shown in the url below.

Answer 5

Yes, I believe "Mimicry" works.

To continue, describe how an animal that looks like a dangerous animal has less of a chance of being eaten than a harmless looking animal. IE, bees sting when provoked, so predators leave them alone... so say how a fly benefits from looking like a bee.

Answer 6

The importance of its defence mechanism, is so other predators, like people wont harm it. People arent afriad of flies, but most are of bees.

Answer 7

Mimicry.
Many insects mimic others with a sting or bite or just taste bad like the Viceroy mimicking the Monarch butterfly.
The only real test is whether the predator can tell the difference.

Answer 8

Its called Mimicry

Answer 9

It's an adaptation known as mimicry.

An example of this would be the non-venomous snake that looks like a coral snake.

Answer 10

If you had asked me 12 years ago I could've told you everything from A-Z but after having a baby, I can't remember s***. Hey, that's science for you. After human beings have kids, thay cant remember diddly squat.
