2.1.3 Thinking and Decision-making


Key Definitions:

Decision-making strategy: a specific algorithm that enables one to solve a multi-attribute choice problem

Descriptive models: models of thinking and decision-making that describe how people actually think and make decisions, taking into account irrational factors
Macro-scale models: models that focus on observable actions and their predictors

Micro-scale models: models that focus on the transient process of making a decision (what goes on in a person’s mind when he/she is making a decision)

Multi-attribute problem: a choice problem involving choosing between several alternatives (options) each characterized by several attributes (parameters)

Normative models: models of thinking and decision-making that describe the rules of rational thinking and decision-making


Essential Understanding

  • Thinking and Decision-making

    Thinking: cognitive process responsible for modifying previously encoded information

    ↳ thinkings results in obtaining new information from existing information

    Decision-making: cognitive process of choosing between given alternatives that involves a choice

→ both are closely connected to make a choice you need to use while thinking

  • Models of Thinking and Decision-making: Two types of thinking

    ↳ can be distinguished into two categories: normative and descriptive models

    → Normative: describe thinking the way it should be

    → Descriptive: describe thinking as it is

  • Theory of Planned Behavior (TPB)

    ↳ sees decision-making as actions that result form behavioral intentions like attitudes, perceived social norms, and perceived behavioral control

    →macro-level theory: looks at visible results of decision-making processes

↳ can be tested to establish its predictive validity: extent of which the combination of variables postulated in the theory actually predicts actual behavior

→ can be seen in Albarracin et al (2001)

  • Adaptive Decision-maker Framework (Payne, Bettman, Johnson 1993)

    ↳ micro-level cognitive model→ zooms in on the transient internal process of making a decision

    → choice of strategy has four meta-goals: maximizing decision accuracy; minimizing cognitive effort; minimizing of negative emotion; minimizing the ease of justification

    ↳ theory claims that factors other than accuracy must be integrated directly into a model of decision-making

    → can be seen in Payne, Bettman, and Johnson (1993)


    Normative and Descriptive Models

  • Normative models

→ describe the “ideal” thinking and decision-making process

Ex: formal logic, statistic theory of probability, normative utility theory

↳ Formal logic describes correct thinking patterns

↳ Statistic theory of probability may be used as a normative model in making predictions

↳ Normative utility theory tells us what is right and wrong in choosing between economically attractive alternatives (define utility with monetary value)

  • Descriptive models

→ describe the processes of thinking and decision-making that way they actually are

→ this is because it’s impossible for people to use normative models to make every decision: they require too many resources and assumes that we are full informed

→ real-life decisions are made under uncertainty and limited time

↳ psychology focuses on this model because of its prediction of people’s model, despite all their biases and fallacies


Theory of Planned Behavior→ Azjen (1985)

↳key: actions are determined by behavioral intentions which are determined by a number of subjective beliefs

  • Macro level

    → looks at behavior at a major scale→ on the visible level of whether an action is performed or not

  • Theory

    → behavioral intention determines effort

    ↳ the stronger it is, the harder we try to implement the behavior

    ↳ can be determined by three factors:

    → Attitudes: individual perceptions of the behavior (positive or negative)

    → Subjective norms: perceived social pressure about this behavior (acceptable or unacceptable)

    → Perceived behavioral control: perception of one’s ability to perform the action

→ the theory holds that if your attitude to a particular behavior is positive, then you believe this behavior is socially acceptable and you believe you can do this action→ thus, this creates a behavioral intention

↳ if the behavioral intention is strong enough, the action will be performed

  • Research

→ requires self-report measures of four predictor variables and one target variable (future behavior itself)

→ predicts that there should be a correlation between attitudes, behavioral control, subjective norms, and behavior to intention

↳ however, behavior should not be significantly directly correlated with attitudes, subjective norms, or perceived control

→ if the theory gives a good fit to empirical data, it should have high predictive validity: four predictor variables collectively should be able to predict the target variable with high probability


Research for TPB

  • Albarracin et al (2001)→ meta-analysis of TPB as a model for condom use

↳key: TPB fits well into observed behavior in the domain of condom use

Aim: investigate the predictive validity of the theory of planned behavior for people’s decisions to use or not use condoms (to prevent STDs)

Method: meta-analysis

Participants: 42 published and unpublished research papers with a total of 96 data sets

Procedure:

→ data sets from published research were combined into a single large data matrix

↳ this was then used to analyze the fit of the model of planned behavior

Results:

↳ TPB turned out to be a successful predictor of condom use

↳ Correlation of 0.51 between intention and behavior

→ significant correlations between behavioral intentions and norms, attitudes, and perceived control

Conclusion:

→ people are morel= likely to use condoms when they have formed an intention to do so based on attitudes, societal norms, and perceived behavioral control

→ confirms the predictive validity of the TPB in the domain of condom use


Adaptive Decision-Maker Framework (ADMF) Theory→ Payne, Bettman, and Johnson (1993)

↳key: people posses a toolbox of decision-making strategies and the choice is guided by emotion-related goals as well as an attempt to achieve accuracy

  • Micro level

→ zooms in on the process of making a decision and looks at what’s happening in a person’s mind when he/she is making the decision

  • Example of a Decision-making scenario

↳ model below shows how people make a choice between alternatives against several attributes

Alternatives

Quality of food

Quality of service

Location

Restaurant 1

Restaurant 2

Restaurant 3

  • Strategies in the Toolbox

Strategy

Alternative or attributed-based?

Process

Weighted additive strategy (WADD)

Alternative

calculate the weight sum (utility) of attributes for each alternative, then choose the one with the highest weighted sum

Lexicographic strategy (LEX)

Attribute

choose the most important attribute and then the option that has the best value for that attribute

Satisficing strategy (SAT)

Alternative

determine a cut-off point for every attribute (no less than…)→ find the option that exceeds the cut-off points on all attributes

Elimination by aspects (EBA)

Attribute

choose the most important attribute and eliminate all options that don’t satisfy your requirements for the attribute

→then choose the second most important attribute and eliminate more

↳ continues until only one is left

Alternative-based strategies: (WADD and SAT)

↳ select an alternative and compare attributes within it

↳ emotional tougher because they include trade-offs

Attribute-based strategies: (LEX and EBA)

↳ select an attribute and compare alternative against it

  • Meta-goals

    ↳ strategy is also guided by four meta-goals, according to the model

Meta-goal

Which Strategy

Maximizing decision accuracy

WADD

Minimizing cognitive effort

LEX

Minimizing the experience of negative emotion

Attribute-based strategies (LEX, EBA)

maximizing the ease of justification

Depends on context but usually SAT and EBA


Research for ADMF

  • Luca, Bettman, and Payne (1997)

↳ key: emotional variables should be directly incorporated into the model

Aim: researchers predicted that if decision-making really adapts to emotion, then people who make choices involving emotionally difficult trade-offs will:

→ process information more extensively

→ choose strategies that allow them to avoid emotionally difficult trade-offs

Method: experiment; independent measures design

Participants: 27 undergraduate students

Procedure:

↳ subjects assumed the role of members of charity and were required to decide which of five candidate children would get financial support

→ each kid was described using five attributes (like living conditions) relevant to the decision-maker model

→ Participants were divided into two groups:

↳ Higher emotion group: participants were told that the other four children were not likely to receive help anywhere else

↳ Lower emotion group: participants were told that the other four children were likely to get help elsewhere

→ Measurement of the DVs was done via “Mouselab”

Mouselab: a software in which presented a table (children and attributes), but the information was hidden and participants and to click the mouse on a cell to reveal the information

↳ recorded the order of how the participants opened the cells

↳ also counted occurrence two types of transitions:

↳ alternative-based transitions (after opening cell A, open a cell for a different attribute but same child)

↳ attribute-based transitions (after opening cell A, open a cell for the same attribute but different child)

Results:

↳ Higher group:

↳ participants spent more time on the task

↳ opened a larger number of cells

↳ engaged more frequently with attribute-based transitions (less emotionally difficult trade-offs)

→ shows that participants were avoiding experiencing negative emotion in the process of making the decision

Conclusion:

→ predictions of the ADMF were confirmed

→ may be concluded that emotional variables need to be directly incorporated into a model of decision-making since the strategies of decision-making are not only influenced by, but directly adapt to, task-related emotion
