Integration of physical and semantic information in object processing.

Abstract

Physiological studies report independent processing pathways for form and colour information. A more-complex picture on human subjects has previously been reported. A sequential matching task was used that was based on a physical property of an object and in which semantic relations between stimuli were manipulated. Performance was affected by semantic information when matching was based on a property of the form of an object (its orientation, shape, or size). Effects of semantic information were eliminated when matching was based on the colour of a local part of an object but were found again when subjects matched pictures on the basis of the percentage of a colour integrated across the shape boundary. The results suggest independent selection mechanisms in vision in which selection by local colour can be based on inhibition of the form-processing pathway whilst processing of the global configuration of the form of an object activates automatically the identification process.

Rule following and rule use in the balance-scale task.

Quinlan et al. [Quinlan, p., van der Mass, H., Jansen, B., Booij, O., & Rendell, M. (this issue). Re-thinking stages of cognitive development: An appraisal of connectionist models of the balance scale task. Cognition, doi:10.1016/j.cognition.2006.02.004] use Latent Class Analysis (LCA) to criticize a connectionist model of development on the balance-scale task, arguing that LCA shows that this model fails to capture a torque rule and exhibits rules that children do not. In this rejoinder we focus on the latter problem, noting the tendency of LCA to find small, unreliable, and difficult-to-interpret classes. This tendency is documented in network and synthetic simulations and in psychological research, and statistical reasons for finding such unreliable classes are discussed. We recommend that LCA should be used with care, and argue that its small and unreliable classes should be discounted. Further, we note that a preoccupation with diagnosing rules ignores important phenomena that rules do not account for. Finally, we conjecture that simple extensions of the network model should be able to achieve torque-rule performance.

Effects of a maximal exercise test on neurocognitive function.

OBJECTIVE: To examine the effects of a maximal exercise test on cognitive function in recreational athletes. DESIGN: A repeated-measures design was used to compare baseline with post-cognitive function and fatigue symptoms after a maximal exercise test. SETTING: Division 1 American Midwestern University, (Michigan State University, Michigan, USA). PARTICIPANTS: 102 male and female recreational athletes. INTERVENTION: Participants in the experimental group (n = 54) were asked to perform a maximal treadmill exercise test to maximal oxygen uptake (VO2 max). Participants in the control group were asked to rest for 15 min. MAIN OUTCOME MEASUREMENTS: All participants were administered a neuropsychological test battery called Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) before and after exercise to measure neurocognitive function and fatigue symptoms. RESULTS: Results revealed a significant group (control, experimental) x time (baseline, post-test 1, post-test 2) interaction for verbal memory composite scores (p = 0.025). Specifically, verbal memory composite scores decreased in the experimental group from baseline to post-test 1 (p = 0.00). These values returned to baseline 3 days after the VO2 max test (p = 0.00). Further analysis on verbal memory composite scores demonstrated significant differences on immediate recall memory (p = 0.00) and delayed recall memory (p = 0.00). No significant differences were observed for visual memory (p = 0.54), motor processing speed (p = 0.68) and reaction time (p = 0.44) composite scores between the experimental and control groups. CONCLUSION: The results of this study suggest that a maximal exercise test attenuated a limiting effect on cognitive function. When utilising a neuropsychological test battery to evaluate a patient who has sustained a head injury, the test should not be administered immediately after a practice or a game session.

Modelling memory functions with recurrent neural networks consisting of input compensation units: II. Dynamic situations.

Modelling the cognitive abilities of humans or animals or building agents that are supposed to behave cognitively requires modelling a memory system that is able to store and retrieve various contents. The content to be stored is assumed to comprise information about more or less invariant environmental objects as well as information about movements. A combination of information about both objects and movements may be called a situation model. Here we focus, in part, on models storing dynamic patterns. In particular, two abilities of humans in representing dynamical systems receive special focus: the capability of representing the acceleration of objects, as can be found in the movement of a pendulum or freely falling objects, and the capability of representing actions of transfer, i.e. motion from one point to another, have been modelled using recurrent networks consisting of input compensation units. In addition, possibilities of combining static and dynamic properties within a single model are studied.
