  • miniature uniaxial force sensor for use within a beating heart during mitral valve annuloplasty
  • provides a hollow core to pass instrumentation
  • Fiber optic transduction eliminates electrical circuitry within the heart, and acetal components minimize ultrasound-imaging artifacts
  • ...4 more annotations...
  • 0–4-N force range
  • errors of 0.13 N (<3.2%)
  • MINIMALLY invasive surgery (MIS)
  • surgeons lose the critical sense of touch during MIS because instruments are passed through ports that mask the surgeon's feel of the internal operating environment.

  • cognitive perspective
  • continuous process integrated in the interaction with the environment
  • normative perspective
  • logic of decision making
  • and rationality
  • decision making is a reasoning or emotional process which can be rational or irrational, can be based on explicit assumptions or tacit assumptions.
  • Logical decision making
  • making informed decisions
  • recognition primed decision approach
  • without weighing alternatives
  • integrated uncertainty into the decision making process
  • A major part of decision making involves the analysis of a finite set of alternatives described in terms of some evaluative criteria.
  • multi-criteria decision analysis (MCDA) also known as multi-criteria decision making (MCDM).
  • differentiate between problem analysis and decision making
  • Problem analysis must be done first, then the information gathered in that process may be used towards decision making.[4]
  • decision making techniques people use in everyday life
  • Pros and Cons
  • Simple Prioritization:
  • Decision-Making Stages
  • Orientation stage
  • Conflict stage
  • Emergence stage
  • Reinforcement stage
  • Decision-Making Steps
  • Outline your goal and outcome
  • Gather data
  • Brainstorm to develop alternatives
  • List pros and cons of each alternative
  • Make the decision
  • take action
  • Learn from, and reflect on the decision making
  • Cognitive and personal biases
  • Selective search for evidence
  • Premature termination of search for evidence
  • Inertia
  • Selective perception
  • Wishful thinking or optimism bias
  • Choice-supportive bias
  • Recency
  • Repetition bias
  • Anchoring and adjustment
  • Group think – Peer pressure
  • Source credibility bias
  • Incremental decision making and escalating commitment
  • Attribution asymmetry
  • Role fulfillment
  • Underestimating uncertainty and the illusion of control
  • a person's decision making process depends to a significant degree on their cognitive style
  • thinking and feeling; extroversion and introversion; judgment and perception; and sensing and intuition.
  • someone who scored near the thinking, extroversion, sensing, and judgment
  • would tend to have a logical, analytical, objective, critical, and empirical decision making style.
  • national or cross-cultural differences
  • distinctive national style of decision making
  • human decision-making is limited by available information, available time, and the information-processing ability of the mind.
  • two cognitive styles: maximizers
  • satisficers
