human decision systems

emotion

model

  • core axes: valence positive-negative; arousal low-high
  • gradation: intensity scaling on these axes, not nuanced category structures
  • polarity tendency: intermediate states collapse toward binary good/bad or safe/dangerous under uncertainty
  • best formalization: component process model (cpm)

    • sequential appraisals: novelty, intrinsic valence, goal relevance, coping potential, norm compatibility

    • each appraisal recruits overlapping neural systems and neuromodulators (dopamine, serotonin, norepinephrine, oxytocin-vasopressin)

    • outputs integrate physiology, expression, motivation, subjective feeling

triggers

  • pattern matching on multimodal sensory and memory inputs
  • subcortical detectors: amygdala, hypothalamus, periaqueductal gray
  • template classes: threat, reward, social cues
  • precedence: rapid valence-arousal tagging before cortical analysis
  • properties: coarse, salience-biased, extended by associative learning
  • bias: high false-positive tolerance favoring survival speed

limitations

  • effective domain: immediate, embodied, survival or social contexts with short feedback cycles
  • failure domain: abstract, long-horizon, probabilistic, systemic contexts with delayed or diffuse feedback
  • failure modes: salience overweighting, binary polarization, delayed outcome discounting

cognition

model

  • function: representation, inference, memory, planning
  • key frameworks:

    • global workspace: conscious access as broadcast across distributed networks
    • predictive processing: hierarchical probabilistic inference minimizing prediction error
    • dual process theory: system 1 fast automatic heuristics, system 2 slow controlled reasoning
  • capability: symbol manipulation, abstraction, long-horizon reasoning
  • substrates:

    • prefrontal cortex: working memory, planning, executive control
    • hippocampus: episodic memory, relational mapping
    • parietal cortex: spatial reasoning, numerical processing
    • language networks: recursive representation, symbolic combination
  • operations:

    • search: combinatorial traversal of state spaces

    • compression: abstraction, categorization, schema formation

    • simulation: counterfactual reasoning, mental time travel

    • integration: multimodal binding and cross-domain mapping

    • meta-cognition: monitoring uncertainty, strategy adjustment

triggers

  • exogenous: explicit problems, language instructions, structured inputs
  • endogenous: goal activation, unresolved prediction errors, novelty detection
  • interaction with emotion: cognition often recruited when affective heuristics insufficient

limitations

  • resource-bound: limited working memory span, serial bottlenecks
  • computational bias: over-reliance on linear causal models, neglect of complex dynamics
  • failure domains: high-dimensional stochastic systems, nonlinear feedback, rare events
  • failure modes: motivated reasoning, confirmation bias, overfitting to symbolic patterns
  • vulnerability: easily hijacked by emotional salience or social conformity

comparison and priorization

  • integrated architecture, not isolated modules
  • emotion: value tagging, urgency assignment, fast prioritization
  • cognition: structured transformation, flexible inference, precision
  • priorization criteria:

    • emotion when horizons seconds-days, stakes personal-social, contexts embodied and survival-relevant
    • cognition when horizons months-decades, stakes systemic-abstract, contexts delayed or probabilistic
  • dichotomy of "emotional vs rational" is a shift in weighting, not separate systems
  • any issue can be reframed emotionally by linking to self or similar others, but this reframing introduces distortions:

    • temporal discounting: undervaluing distant risks relative to immediate ones
    • salience bias: overweighting vivid or personal stories relative to systemic dynamics
    • binary collapse: compressing complex trade-offs into good/bad poles
    • misprioritization: allocating urgency to symbolically salient but low-probability threats
    • neglect of scale: privileging individual-level affect over aggregate or statistical outcomes
  • any issue can also be reframed cognitively by abstracting from direct affective relevance, but this reframing shifts emphasis:

    • depersonalization: stripping urgency from personally critical issues

    • over-abstraction: privileging general models over embodied signals

    • delayed calibration: acting too slowly where immediate response is adaptive

    • probability fixation: overweighting statistical reasoning at cost of situational salience

    • underweighting of motivation: accurate models without corresponding drive to act

emotional simulation

  • approaches:

    • associative learning models of fear conditioning
    • reinforcement learning with value functions and prediction errors
    • computational appraisal models (cpm-like)
  • ai applications:

    • deep learning for sensory trigger detection
    • reinforcement learning for affect-like value assignment
    • large language models for appraisal-like text evaluation without grounding
    • hybrid architectures combining recognition with appraisal evaluators
  • chatbot design:

    • multimodal affect embeddings stored in an emotion vector space

    • valence-arousal and appraisal dimensions as indices

    • sequential appraisal pipeline applied to embeddings

    • reasoning and retrieval weighted by affect vectors alongside semantics
