My research interests include human learning and memory; judgment and decision-making; computational modeling, especially with neural network models; amnesia, the hippocampus, and the implicit-explicit distinction; economic psychology and rationality.
My research in the Centre for Economic Learning and Social Evolution, an ESRC Research Centre based at UCL, is concerned with understanding economic learning and behavior, particularly from a rational or Bayesian perspective. In particular, I have focused on several classic issues in judgment and decision making such as multiple-cue learning, base-rate biases, and the rule of extension in probability judgment, and have attempted to provide accounts of these effects using adaptive network models (see Lagnado & Shanks, 2002). Also, I have been looking at the issue of whether learning can in general be studied from an ‘optimal’ perspective. In research with Richard Tunney I used a game-theoretic framework to re-examine people's ability to optimize their payoffs in simple choice tasks (see our 2 papers in JBDM ), and in work with Maarten Speekenbrink, Dave Lagnado, and Ben Newell I have been developing rational models of learning and using them as benchmarks for evaluating decision making and learning.
Causal inference lies at the heart of many aspects of cognition. In work that started with my PhD thesis, I have been investigating links between causal reasoning and elementary associative learning and error detection. A major theoretical goal has been to demarcate the boundaries between associative processes on the one hand and cognitive ones on the other. The edited volume (Shanks, Holyoak, & Medin, 1996) brought together many of the researchers in this area and a recent paper (Shanks, 2007) updates this. My current work on this topic is using formal model-fitting procedures to compare theories of causal and contingency judgment. Also, work led by Paul Fletcher is studying neural correlates of causal and associative learning.
Lastly, the current textbook view of memory proposes that there are multiple systems dealing with different forms of memory: for example, the hippocampus controls ‘declarative’ or ‘explicit’ memory while ‘procedural’ or ‘implicit’ memory depends on other neural systems. I have been working for several years on an alternative and more parsimonious framework which views memory as unitary and which explains dissociations between different memory tests as emerging not from the operation of distinct underlying systems but rather as emergent properties of interactions between memory representations and the tests used to probe them. With Annette Kinder, Chris Berry, Rik Henson and others I have employed computational modelling techniques to simulate memory dissociations using models which employ only a single memory system. The article by Shanks, Channon, Wilkinson, and Curran (2006) describes some of our recent work on implicit learning in organic and pharmacological amnesia. Our latest work involves extending signal detection theory to deal with implicit memory tasks. Alongside this work, several of my papers (e.g., with Andrea Smyth, Lee Rowland, and Leonora Wilkinson) have questioned the notion that learning can occur unconsciously, automatically, or more generally ‘noncognitively’.
