cognitive-neuroscience

Layer 3 — Biology24 concepts in this subtree

Cognitive neuroscience — NSF BIO / IOS cross-listed with psychology at the mind-brain interface grain; mechanistic study of perception, attention, memory, language, decision-making, and executive function through the neural substrate. …

Signal-detection theory: d' = z(H) − z(F), c = −(z(H)+z(F))/2
Mental chronometry: RT(n) = a + b·n; Sternberg slope b ≈ 38 ms/item
Working memory: Miller 7±2 chunks; Cowan 4±1; Baddeley-Hitch 4-component
d'-antisymmetry: d'(H,F) + d'(F,H) = 0; d'(H=F) = 0 (chance)
Stroop interference: RT_incong − RT_cong = 150 ms at anchor (RT_cong=600, RT_incong=750)
Sternberg scanning: RT(n) = 400 + 38n ms; RT(4) − RT(1) = 3·38 = 114 ms
Drift-diffusion model (DDM): dx = v·dt + dW_t; absorbing barriers ±a/2; ⟨T⟩=(a/2v)·tanh(av/2)
Fitts' law: MT = a + b · log₂(2A/W); ID = log₂(2A/W); Fitts' 1954 information-theoretic aiming
Hick-Hyman law: RT = c + d · log₂(N+1); choice-RT scales with information H in bits
DDM: ⟨T⟩=(a/2v)·tanh(av/2); P_upper=1/(1+e^{−av}); ⟨T⟩|_{v→0}=a²/4; P|_{v=0}=1/2
Fitts: MT = a + b·log₂(2A/W); ID(A=8,W=1)=4; doubling A or halving W → +1 bit ID
Hick: RT = c + d·log₂(N+1); RT(N=1)=c+d, RT(N=3)=c+2d, RT(N=7)=c+3d; slope/bit = d
