Cognitive science research to revolutionize the legal system - 0 views

  •  
    What if a jury could decide a man's guilt through mind reading? What if reading a defendant's memory could betray their guilt? And what constitutes 'intent' to commit murder? These are just some of the issues debated and reviewed in the inaugural issue of WIREs Cognitive Science, the latest interdisciplinary project from Wiley-Blackwell, which for registered institutions will be free for the first two years. In the article "Neurolaw," in the inaugural issue of WIREs Cognitive Science, co-authors Walter Sinnott-Armstrong and Annabelle Belcher assess the potential for the latest cognitive science research to revolutionize the legal system.

Cognitive Psychology and Cognitive Neuroscience/Decision Making and Reasoning - Wikiboo... - 0 views

  •  
    No matter which public topic you discuss or which personal aspect you worry about - you need reasons for your opinion and argumentation. Moreover, the ability of reasoning is responsible for your cognitive features of decision making and choosing among alternatives.

Anterior cingulate cortex - Wikipedia - 0 views

  • the dorsal anterior cingulate cortex is primarily related to rational cognition while the ventral is more related to emotional cognition.
  • early learning and problem solving
  • processing top-down and bottom-up stimuli and assigning appropriate control to other areas in the brain.
  • ...5 more annotations...
  • ACC response in Stroop task experiments (designed to measure adherence to sequential decision-making paths) remains relatively elevated in typical human subjects, as the alternative - spontaneity - is sacrificed.
  • A typical task that activates the ACC involves eliciting some form of conflict within the participant that can potentially result in an error.
  • inability to detect errors, severe difficulty with resolving stimulus conflict in a Stroop task, emotional instability, inattention, and akinetic mutism
  • difficulty in dealing with conflicting spatial locations in a Stroop-like task and having abnormal ERNs
  • appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate, as well as rational cognitive functions, such as reward anticipation, decision-making, empathy and emotion.

Anterior cingulate cortex regulation of sympathetic activity -- Luu and Posner 126 (10)... - 0 views

  • lesions to the ACC do not produce massive or consistent cognitive deficits.
  • patients with ACC lesions do demonstrate performance deficits on the Stroop task and other tasks that have been shown to activate the ACC
    • Rudy Garns
       
      Greene refers to the Stroop Effect and the ACC; ACC is thought to monitor conflict between prepotent social-emotional moral responses and cognitive-utilitariann responses.
  • apathetic and unconcerned when significant events occur, such as making mistakes
  • ...8 more annotations...
  • divide the ACC into subregions that are separately responsible for affective and cognitive processes
  • adaptive
  • the mechanisms by which mental processes are integrated with bodily systems.
  • these processes produce autonomic reactions that signal the requirement for adaptive control of behaviour.
  • regulation of autonomic processes
  • the ACC is involved in detecting when strategic control is required and that the lateral prefrontal cortex is involved in strategic control
  • the anterior cingulate is very metabolically active at rest
  • changes in heart rate in both cognitive and motor tasks related to the strength of activation in the ACC.

Is anterior cingulate cortex necessary for cognitive control? -- Fellows and Farah 128 ... - 0 views

  • activated when tasks require the ongoing adjustment of the allocation of attention.
  • All four subjects with dACC damage showed normal adjustments in performance following manipulation of response conflict in both Stroop and go–no go tasks
  • damage to the dACC did not impair the phenomenon of post-error slowing, nor alter the ability to adjust performance in response to explicit speed or accuracy instructions.
  • ...2 more annotations...
  • cognitive control, as assessed by four different measures in two different tasks, appears to be intact in these subjects, arguing against a necessary role for dACC in this process.
  • cognitive control.

Neuroscience: Small, furry … and smart - 0 views

  • Much of the work involves making an adult brain behave more like a younger, more flexible version of itself by increasing the organ's plasticity.
  • neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.
  • Tsien created Doogie by overexpressing a subunit of the NMDA receptor called NR2B. This kept the receptors open for longer, strengthening the synaptic link and making it easier for disparate events to be linked together.
  •  
    Tsien, based at Princeton University in New Jersey at the time, named his creation Doogie after the teenage genius in the television programme Doogie Howser, MD. The work was one of the earliest examples of neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.

The Legal Brain: How Does the Brain Make Judgments about Crimes? - 0 views

  •  
    In our legal system, judges and juries have to assign responsibility for crimes and decide on appropriate punishments. A new imaging study reveals which area of the brain plays a key role in these cognitive processes. (Scientific American)

Neuroscience and Decision Making - 0 views

  •  
    This paper reviews the cognitive neuroscience of decision making and summarizes a talk given by the author at a SOL-UK workshop entitled 'Improving the Decision-Taking Process in Institutions' and held at the London School of Economics on 23rd June, 2006.\n\nAn operational definition of decision making is discussed as it relates to neuroscientific research and application. Neuroanatomical and cortico- subcortical as well as cortico-cortical connections between brain structures are then reviewed as they relate to the decision making process. Finally, while biased toward the individual level of analysis, extrapolations to the larger group environment are also discussed.

Neuroscientists Map Intelligence In The Brain - 0 views

  •  
    Neuroscientists at the California Institute of Technology (Caltech) have conducted the most comprehensive brain mapping to date of the cognitive abilities measured by the Wechsler Adult Intelligence Scale (WAIS), the most widely used intelligence test in the world. The results offer new insight into how the various factors that comprise an "intelligence quotient" (IQ) score depend on particular regions of the brain.

Multitasking May Not Mean Higher Productivity : NPR - 0 views

  •  
    A new study says so-called "heavy multitaskers" have trouble tuning out distractions and switching tasks compared with those who multitask less. And there's evidence that multitasking may weaken cognitive ability. Stanford University professor Clifford Nass explains the work.

Brain activity associated with honest and dishonest decisions. - 0 views

  •  
    What makes people behave honestly when confronted with opportunities for dishonest gain? Research on the interplay between controlled and automatic processes in decision making suggests 2 hypotheses: According to the "Will" hypothesis, honesty results from the active resistance of temptation, comparable to the controlled cognitive processes that enable the delay of reward. According to the "Grace" hypothesis, honesty results from the absence of temptation, consistent with research emphasizing the determination of behavior by the presence or absence of automatic processes.

Where is my mind? - 0 views

  • Is what my robot does when it ‘decides’ to change course a sort of thing which if it had happened inside the robot, ‘I would have had no hesitation in accepting as part of [a] cognitive process?’
  • But how am I to understand the hypothesis that it would (or wouldn’t) have changed course if it had collided with the couch in my head?
  • His real argument is that, barring a principled reason for distinguishing between what Otto keeps in his notebook and what Inga keeps in her head, there’s a slippery slope from the one to the other.
  • ...4 more annotations...
  • The mark of the mental is its intensionality (with an ‘s’); that’s to say that mental states have content; they are typically about things.
  • What I should have said isn’t that only what’s literally and unmetaphorically mental has content, but that if something literally and unmetaphorically has content, then either it is mental (part of a mind) or the content is ‘derived’ from something that is mental. ‘Underived’ content (to borrow John Searle’s term) is the mark of the mental; underived content is what minds and only minds have.
  • Externalism needs internalism; but not vice versa. External representation is a side-show; internal representation is ineliminably the main event.
  • your internal model of the world contains stuff that the world itself does not; this happens not just when your beliefs are false but also when they are hypothetical (‘if there are clouds, there will be rain’ can be true even if there aren’t any clouds); or when they are modal (‘it might rain’ can be true even if it doesn’t rain); or when they are in the past or future tense (‘it used to rain here a lot’ can be true even if it doesn’t rain here anymore).
  •  
    There is a gap between the mind and the world, and (as far as anybody knows) you need to posit internal representations if you are to have a hope of getting across it. Mind the gap. You'll regret it if you don't. (Jerry Fodor review of Clark)
