The neurobiological basics of motivation
- Hunger: The hypothalamusand parts of the amygdala form “the centre of saturation and eating”
- Social interaction: The peptide hormone oxytocin (release during: birth, lactation, orgasm) promote feelings of bonding and trust
- Amplifier pathway: The mesolimbic dopamine-system controlles amplification, the reward system
The theory of motivation: subjective orientation
Motives are divided into primary and secondary motives. Even though sexual motives belong to the primary motives, they do not serve to maintain homeostasis.
|Primary motives||Inherent motives: maintaining homeostatis and sexual motives||Hunger, thirst, sleep, exploration, freedom from pain, breathing (oxygen), sex|
|Secondary motives||Learned motives which are not needed for homeostatis (lower biological significance)||Power, performance, prestige, connection|
Theories of motivation
- Intrinsic motivation: inner, “self-motivation” to do something
- Extrinsic motivation: motivation based on outer amplifiers, rewards (i.e. money)
The ethological model: the instinct theory
This approach supports the position that most of the animal and human behaviours have a genetic basis. The central question of the study of instinct (ethology) is:
Which parts of the behaviour are inherent and which are learned individually?
The motive here is a state of deficiency and the individual is searching for stimuli to eliminate this state of deficiency. K. Lorenz observed various species and came to the conclusion that specific instinctive acts take place in a way that is standardised to the maximum extent.
The sequence of the instinctive act according to Konrad Lorenz (1937)
|1||The impetus elicits appetitive behaviour|
|2||A key stimulus or a dummy appears.|
|3||A fixed action pattern (FAP) elicits|
|4||An orientating response and|
|5||The final act of consummatory is initiated and the lack need is satisfied.|
Important terms regarding the ethological model in detail
Learned key stimuli that are not present at birth are called imprinting. This imprinting that takes place during the short, learning-sensitive phases are irreversible.
Inherent key stimuli are, for instance, a hungry infant’s appetitive behaviour and the schema of childlike characteristics with its corresponding behaviour of affection and protection. With this schema you can also illustrate the term dummy very well: We react to stuffed toys with big eyes, small noses, and round faces in a similar way we react to a cute baby face: we pick them up and caress them.
|Final act||The final act of consummation leads to the strongest decrease in the motivation to act according to a defined behavioural program.||Blackbirds: open beak, swallow the food, satisfaction of need by saturation|
|Displacement behaviour||The tension between two action tendencies leads to behavioural inhibition and a new action, which is different from the two tension producing actions.||Scratching one’s head, gnawing one’s nails, cracking one’s knuckels|
|Vacuum activity||The motive is so strong that it is triggered without a key stimulus.||The hunting behaviour of a bird (according to Lorenz’s experiments). Despite the absence of insects, the entire process of catching flies is carried out.|
Maslow’s hierarchy of needs (1971)
Maslow assumes that primary needs have to be satisfied first before secondary needs can become relevant. Thereby he supports a humanistic image of humankind:
Only the extended motivations represent man.
Every human being potentially strives for self-actualisation.
The needs for self-actualisation (need for transcendence) can only be satisfied in a small fraction of people. Transcendence means to give life a higher meaning, to feel in harmony with the whole.
The learning theory approach
The learning theory approach is based on the learning process according to the principles of operant conditioning.
The motivation consists of the results of two basic questions:
- How attractive or valuable are the task values/task goals?
- How high is the subjective probability that this result happens and how high is the associated expectancy?
The evolutionary psychological approach: voluntary actions
Actually, you would rather to go to the lake now instead of studying in the library for the preliminary examination. Your will makes it possible for you to pursue important goals even though there is no motivational basis at the moment.
The tendency (intention) is the basis for the voluntary actions. The volitional (volition = will/will power) process here is stronger than the motivational process (i.e. fasting despite hunger). The Rubicon model summarizes the action phases.
The rubicon model of action phases (Heckhausen et al., 1987)
Strategies for the evolutional action control
- Motivation control: targeted increase of motivation with renewed focus on the goal („I definitely want to pass the preliminary examination!“)
- Environmental control: change in the environment in order to achieve the goal more easily (learning in the library instead of at home with a view of the park)
Trip to the clinic: The transtheoretical model
The transtheoretical model TTM according to Prochaska and DiClemente should enable therapists to better evaluate and influence their patients‘ behaviour. Especially in patients with dependency issues (see below), this is important for therapeutic decisions. The TTM consists of six steps:
The therapeutic approach: It is important to work in synchronised phases! How do you, for instance, convince a patient to stay sober if he is not even aware of the health risk of substance abuse? The following table summarises which main strategy to follow in each phase:
|precontemplation||Creation of an awareness of the problem|
|contemplation||Resolve ambivalent thoughts|
|preparation||Precise focus on the goal with the step-by-step plan|
|action||Boosting one’s trust in one’s own strengths|
|maintenance||Preventative behaviour against a backslide|
|termination||The behaviour to achieve the goal has become “normal”|
The motivation conflicts
It is rare that there is just one motivation or one tendency toward need. On the contrary: Often there are simultaneous different motivational tendencies in us and we have to decide on one. Hereby conflicts arise.
The 3 conflict typologies by Lewin (1931)
- Appetence = Tendency, which aims on lust gain during the action
- Aversion = Tendency, action without avoiding potential lust gain
- Appetence-Appetence-conflict: The approach conflict
In an appetence conflict, the affected individual has to decide between two positive alternatives.
Example: You have been admitted to study veterinary medicine as well as human medicine and now have to decide on one.
Aversion-Aversion-conflict: The avoidance conflict
In an aversion conflict, the affected individual has the choice between two negative alternative, in other words choosing the “lesser evil”.
Example: You contemplate working two hours overtime in the evening versus getting up earlier tomorrow in order to finish writing the discharge letters.
Appetence-aversion conflict: The ambivalence conflict
In an appetence-aversion conflict, the individual’s goal has both, negative and positive aspects at the same time (“two sides of a coin“). He is disgusted and attracted simultaneously to fulfil the tendency toward the need.
Example: A depressed patient would like to undergo therapy with antidepressants but fears the side affects of gaining weight.
Double appetence-aversion conflict by Miller (1944)
The fourth type of conflict extends Lewin’s simple typology by adding the double appetence-aversion conflict. Here, the individuals have to decide between two alternatives which each have positive and negative aspects.
Example: Do you choose the low paying residency in your favourite city over the highly paid job at a rural hospital in the periphery?
The achievement motivation
The will to want to beat themselves or others in their achievements is called achievement motivation. People with high achievement motivation choose tasks that are always a degree more challenging: Only if failure or success can be the result of a task, it is possible to assess a quality standard. Aside from positive responses like joy and pride, one is motivated by the desire for increasing efficiency: The road to success is optimised more and more in variations.
The risk-preference-model by Atkinson (1957): Expectancy x value
You want to get a B on your preliminary examination while your fellow student is completely satisfied with a D. The basic question of the Atkinson model is the following:
Why do people set goals at different levels?
Choosing a goal (choosing the difficulty of the task) = the probability of success (expectation) x appeal of success (value)
- Moderately difficult tasks provide information about one’s own efficiency because success or failure is possible.
- Easy tasks are executed without any problem and do not lead to positive effects.
- Difficult tasks have a low probability of success. If success occurs, however, the positive effects are that much greater.
- Success motivated individuals choose moderately difficult tasks
- Failure motivated individuals choose very easy or very difficult tasks
The attribution theory
Depending on one’s explanatory style, people justify their successes and failures. These causal attributions are divided into different attributional dimensions: internal/external, stable/unstable, and specific/global. Read everything regarding explanatory styles here.
The fundamental attribution error: Actor-observer bias
The observers’ attitude to relate one’s behaviour primarily back to human behavioural traits and putting situational factors aside (i.e. aggressive behaviour), is called fundamental attribution error. The actor would explain his behaviour exactly the opposite way and primarily blame the situation for his behaviour.
Addiction: Looking for more
Definition of addiction (WHO): Addiction is a psychological and physical state, which is characterised by the fact that an individual feels an insurmountable desire for a certain substance or a certain behaviour despite physical, mental or social disadvantages. He can no longer control this and is dominated by this desire.
The topic addiction belongs in the article about motivation because addicts act very purposefully: To get the “pleasure“ of the addictive substance is usually the only motive for addicts and this goal is pursued consequently. One differentiates between substance dependencies and substance independent addictions (food addiction, gambling addiction).
Hallucinogens (LSD, mescaline), opiates (morphine, heroin), cannabis, alcohol, nicotine, and analgesics are counted among psychoactive substances.
According to DSM-IV, dependency exists if three of the following criteria are present:
- Development of tolerance
- Physical withdrawal symptoms
- The substance is consumed in larger amounts and longer than intended
- The substance intake can no longer be controlled
- A lot of time is spent on procurement and consumption of the substance and other factors (work, family, leisure activities, …) are neglected
- The substance is consumed despite physical and psychological damages
Important facts about alcohol, nicotine, and drugs
- Alcohol abuse: Alcohol dependence is most common in men in western industrialised nations, in women it is the second most common mental illness (88-94% of the adult population drinks alcohol regularly)..
- Nicotine abuse: In Germany, 17.4 million people abuse nicotine.
- Drug abuse: In Germany, between 1.4 and 1.6 million people are dependent on drugs which were initially prescribed by a physician, i.e. Benzodiazepines.
How does a dependence arise?
Several factors play a role in developing dependency. The WHO speaks of a multifactorial model of explanation.
|Personal factors||Negative self-image; tendency to reward oneself quickly; impulsive, antisocial behaviour|
|Environmental factors||Family: disinterested and unstable environment, little to no emotional attention, little scholastic achievements, status gain in peer groups (testing courage, power games, “coolness“), easy availability of substances (especially alcohol, nicotine)|
|Effect of the drug||Enhancing effect for consumers, effect on the mesolimbic dopamine system (reward system) with tolerance development, withdrawal symptoms associated with abstinence|
Psychosocial effects of the drug
Theoretical learning processes are important to explain the origin of dependence. On the one hand, operant conditioning takes place: The drug leads to relaxation (positive reinforcement), the drug prevents negative emotions/situations or withdrawal symptoms disappear (negative reinforcement). Classically conditioned are situational and social triggers such as getting together at a bar, parties, conflict situations (partnership, supervisors, …).
Favourite exam questions regarding motivation
The answers are below the references.
1. Different hormones and transmitter substances belong to the neurobiological bases for the origin of motivation. Which behaviour is mainly promoted by oxytocin?
- Sensation Seeking
- Competitive behaviour
- Maternal bonding-behaviour
- Defence reactions (Fight and Flight)
2. First and foremost, primary motives have an important function. They are:
- To secure the psychological balance
- To encourage performance and to gain rewards (positive reinforcement)
- To support study-theoretical processes (operant and classical conditioning)
- To match individual interest for the communities’ good
- To satisfy simultaneously physical and psychical needs
3. A 15-year-old student regularly smokes cannabis with her clique. So far, she has not considered stopping her drug consumption. What stage in the trans-theoretical model according to Prochaska and DiClemente would you put her in?
