Classical conditioning

Learning that “one event predicts another”; or more specifically, a type of associative learning in which “a neutral stimulus comes to elicit a response when it is associated with a stimulus that already produces that response” (Gazzaniga et al., 2016, p. 226). 

Climate crisis

is a huge threat to the planet and all living things. It results from man-made changes to the atmosphere and the climate system, in particular through massive greenhouse gas emissions - often referred to as "climate change". Its effects are real, permanent, difficult to control and can be seen and felt worldwide. They are particularly evident in the form of rising sea levels, extreme weather events, droughts, heatwaves and the extinction of species. The climate crisis not only jeopardises the environment, but also the stability of human societies. This reveals a clear social injustice: the most disadvantaged and least resilient population groups are affected the most. Psychologically speaking, the climate crisis can trigger severe stress (also known as climate stress), as the extent of the threat is difficult to grasp and cannot be controlled individually. In order to cope with and contain it, people must work together to make fundamental changes in social, political, economic and ecological relationships.

Climate stress

describes the physical and emotional reactions to the direct and indirect consequences of the climate and biodiversity crisis. Climate stress is complex and is caused by different types of stressors. These can be, for example, stressors that affect the person directly, such as very high temperatures during a heatwave. Social stressors can arise, for example, when relatives die as a result of climate-related natural disasters. Ecological stressors, on the other hand, describe negative changes in the environment, e.g. when the death of forests is witnessed. These stressors can occur directly, for example as a result of an extreme weather event such as a severe storm. They can also be communicated via the media, for example through reports on climate-related natural disasters. Climate stress can also develop from fears and other unpleasant feelings such as frustration and hopelessness about possible future effects of the climate crisis. The psychological effects of climate stress can vary, ranging from anxiety and worry to more severe psychological distress such as anxiety and depression. In addition, various stress symptoms and other stress-related illnesses can occur. These can affect well-being and quality of life. It is therefore important to develop effective coping strategies and measures.

An inherited universal psychic system that stores potentials and capacities for patterns of thought and behavior, consisting of “pre-existent forms, the archetypes, which can only become conscious secondarily and which give definite form to certain psychic contents” (Jung, 1959a, p. 42-4). Also see the entries for “archetypes” and “instincts.”

commons dilemma

The difficulty of managing shared natural resources - which results in many of the environmental problems that exist today - was allegorised in a social dilemma called “The Tragedy of the Commons” (also called the commons dilemma) by Garrett Hardin, an ecologist (1968). Hardin described a field for grazing cattle which is shared by a village. The field must not be overused otherwise the grass will get used up, perhaps to a stage when replenishment is no longer possible. If everyone allows one cow onto the land, there is enough for all. If an individual villager allows more than one cow to graze, that villager - called a free-rider - will benefit. But if others follow suit, everyone suffers as the resource becomes depleted. The dilemma is therefore the choice between short-term individual and long-term collective interests. Taking more than others (competition) may provide temporary benefits to some, but agreeing to limit your use of the resource (cooperation) ultimately benefits all. A good example of the temptation not to cooperate in a commons dilemma is our reluctance to limit our fuel usage. Have you ever reasoned to yourself like this: “If I don’t use up some of the remaining fuel in the world, someone else will; all I can do is delay the inevitable depletion by a few seconds”? (See laboratory social dilemmas for a description of how this works experimentally.)

comparative suffering hypothesis

states that seeing the offender suffer from fate is sufficient for victims to feel satisfaction

Compensatory control theory

was developed to understand how people  maintain the belief that they live in an orderly and stable world when experiencing fluctuations in perceived personal control; when personal control is perceived to be low, people can compensate by affirming beliefs in external sources of control, such as supernatural agents and governmental bodies

A system of ethics that, at its simplest, uses the consequences of our actions to determine whether they are right or wrong. (This is in contrast to a deontological system of ethics, in which actions have intrinsic moral value, regardless of their consequences.)


Consolidation happens when new information is transferred from short-term memory (which can be easily disturbed) to long-term memory (which is more stable). Memory consolidation requires time.    


The step in the memory process in which a memory is stabilized allowing short-term memories to be converted into long-term memories

control condition

Many psychological experiments are designed to examine the impact of a specific variable (in the case of this paper: sleep deprivation) on different facets of human functioning (in the case of this paper: decision making). To examine this impact scientifically, two groups (also called conditions) are compared: the experimental condition in which the variable of interest is present (i.e., sleep deprivation) and a control condition in which the variable is not present (i.e., a well-rested group). Apart from the variable of interest, both conditions have to be as similar as possible. The difference in functioning (i.e., decision making) between both groups informs about the impact of the variable under study.


In the context of a social dilemma, cooperative behaviour acts in the interests of the collective, rather than acting in the individual’s interests. This will involve forgoing immediate benefits to the individual in order to preserve the shared resource. The alternative behaviour is competition, where the individual does whatever is necessary to gain maximum personal benefit.


the process of managing taxing circumstances, and seeking to reduce or tolerate stress or conflict


A steroid hormone belonging to a group of hormones called glucocorticoids; produced in humans by the zona fasciculate of the adrenal cortex in the adrenal gland (near kidney)


phenomena are phenomena that are physically implausible or nonexistent; in psychology mostly known for counterfactual thinking: pondering about what would have happened if one had done something different at a certain point in time; so though the phenomenon can easily be thought about, it’s just impossible in the present reality


phenomena are phenomena that are at odds with factual or logical reasoning; ironically, counterintuitive can also stand for phenomena at odds with gut feelings and intuition, which are often disproven; take the earth for an example, the idea that the earth is flat is an intuitive idea; the discovery that the earth was a round spheroid, is therefore a counterintuitive idea; yet, this doesn’t mean that the idea isn’t true: it’s just unlikely to be thought


one of the terms proposed for the racial mixture represented by a person with one indigenous and one mestizo parent
