Archaeology and cognitive evolution

Archaeology can provide two bodies of information relevant to the understanding of the evolution of human cognition--the timing of developments, and the evolutionary context of these developments. The challenge is methodological. Archaeology must document attributes that have direct implications for underlying cognitive mechanisms. One example of such a cognitive archaeology is found in spatial cognition. The archaeological record documents an evolutionary sequence that begins with ape-equivalent spatial abilities 2.5 million years ago and ends with the appearance of modern abilities in the still remote past of 400,000 years ago. The timing of these developments reveals two major episodes in the evolution in spatial ability, one, 1.5 million years ago and the other, one million years later. The two episodes of development in spatial cognition had very different evolutionary contexts. The first was associated with the shift to an open country adaptive niche that occurred early in the time range of Homo erectus. The second was associated with no clear adaptive shift, though it does appear to have coincided with the invasion of more hostile environments and the appearance of systematic hunting of large mammals. Neither, however, occurred in a context of modern hunting and gathering.     

Inpatient cognitive therapy: Detours,potholes, and roadblocks along the routes of progress

Developing innovative treatment approaches for psychiatric inpatient settings is an emerging area of interest. This paper delineates the detours and circuitous paths treatment with difficult patients often takes. Differences between typical outpatient and inpatient care are described and the obstacles to cognitive therapy that inpatients present are discussed. The role of case conceptualization is emphasized as a way to promote increased effectiveness. Finally, methods for maximizing therapeutic opportunities with inpatients are suggested.Robert D.

Route-based travel and shared routes in sympatric spider and woolly monkeys: cognitive and evolutionary implications

Many wild primates occupy large home ranges and travel long distances each day. Navigating these ranges to find sufficient food presents a substantial cognitive challenge, but we are still far from understanding either how primates represent spatial information mentally or how they use this information to navigate under natural conditions. In the course of a long-term socioecological study, we investigated and compared the travel paths of sympatric spider monkeys (Ateles belzebuth) and woolly monkeys (Lagothrix poeppigii) in Amazonian Ecuador. During several field seasons spanning an 8-year period, we followed focal individuals or groups of both species continuously for periods of multiple days and mapped their travel paths in detail. We found that both primates typically traveled through their home ranges following repeatedly used paths, or “routes”. Many of these routes were common to both species and were stable across study years. Several important routes appeared to be associated with distinct topographic features (e.g., ridgetops), which may constitute easily recognized landmarks useful for spatial navigation. The majority of all location records for both species fell along or near identified routes, as did most of the trees used for fruit feeding. Our results provide strong support for the idea that both woolly and spider monkey use route-based mental maps similar to those proposed by Poucet (Psychol Rev 100:163–182, 1993). We suggest that rather than remembering the specific locations of thousands of individual feeding trees and their phenological schedules, spider and woolly monkeys could nonetheless forage efficiently by committing to memory a series of route segments that, when followed, bring them into contact with many potential feeding sources for monitoring or visitation. Furthermore, because swallowed and defecated seeds are deposited in greater frequency along routes, the repeated use of particular travel paths over generations could profoundly influence the structure and composition of tropical forests, raising the intriguing possibility that these and other primate frugivores are active participants in constructing their own ecological niches. Building upon the insights of Byrne (Q J Exp Psychol 31:147–154, 1979, Normality and pathology in cognitive functions. Academic, London, pp 239–264, 1982) and Milton (The foraging strategy of howler monkeys: a study in primate economics. Columbia University Press, New York, 1980, On the move: how and why animals travel in groups. University of Chicago Press, Chicago, pp 375–417, 2000), our results highlight the likely general importance of route-based travel in the memory and foraging strategies of nonhuman primates.

Brain and cognitive evolution: forms of modularity and functions of mind

Genetic and neurobiological research is reviewed as related to controversy over the extent to which neocortical organization and associated cognitive functions are genetically constrained or emerge through patterns of developmental experience. An evolutionary framework that accommodates genetic constraint and experiential modification of brain organization and cognitive function is then proposed. The authors argue that 4 forms of modularity and 3 forms of neural and cognitive plasticity define the relation between genetic constraint and the influence of developmental experience. For humans, the result is the ontogenetic emergence of functional modules in the domains of folk psychology, folk biology, and folk physics. The authors present a taxonomy of these modules and review associated research relating to brain and cognitive plasticity in these domains.     

Memory for animal tracks: a possible cognitive artifact of human evolution

Although many human behaviors are held to have adaptive significance, specific examples of behaviors that represent direct holdovers from the ancient world have been few, particularly in the cognitive realm. In the present research, the authors tested the hypothesis that such cognitive examples might in fact exist and be experimentally verifiable. They suggested that human predispositions to learn basic aspects of hunting with relative ease might be "left over" from human evolution in the pre-agricultural past. This hypothesis was tested in 3 experiments with reference to the learning and recall of animal tracks, an activity of probable high adaptive significance within the area of visual memory. Undergraduate students selected at random learned and recalled animal tracks with significantly greater ease than they recalled other animate and inanimate items. A single exception lay in relatively unfamiliar kitchen implements, which were recalled with greater facility than were animal tracks, consistent with current theoretical considerations. Results indicate that direct behavioral holdovers from the ancient world may exist in the cognitive realm and that these may be accessed experimentally and predictably under appropriate conditions.     

Memory for routes

Two experiments examined the acquisition of cognitive maps of two intersecting routes through an urban area. In the presentation stage of the experiments, slides of the two routes were shown in order to simulate travel along the routes. The number of presentations of the slides was varied. In the test stage, subjects made directional and distance judgements from memory between places on the routes. The results suggest that from the start of acquisition of the spatial layout of the routes, subjects used network schemata in which both routes were combined, rather than a separate scheme for each route which were later combined. During initial acquisitions of the routes, a direction of travel bias was found such that spatial judgements from memory tended to be more accurate in the direction of travel along the routes than in the opposite direction. The findings imply that, at least during early acquisition, the spatial properties of the routes were encoded in terms of sequential associations.     

An era of webs: Technique,technology and the new cognitive (r)evolution

This paper explores the relationship between technology and technique in the use of computers as tools and how it is leading cognitive sciences into to an era of “webs.” Ernst Kapp suggested that it is humans who determine the “appropriate form” of any tool through the way they use and think about it; Douglas Engelbart, a pioneering computer researcher suggested that tools change to meet our expectations pushing us to understand the world in different ways. These two interrelated observations about technology are especially salient for our burgeoning information age. The current intersection of technologies leads to two competing visions of the computer – both deeply influenced by the concept of human–computer symbiosis – and to very different conceptions of human thinking. The vision of computer as recreation of human thinking, heavily influenced by the development of tools such as the personal computer and object-oriented programming, leads to viewing ideal human thinking as efficiently designed, well organized, and locally regulated by executive functions. The second vision of computers, as augmenting the human mind by extending brain activity out into the information universe, leads to web or trails related themes that focus on non-linear, non-hierarchical inter-linking of information into cohesive patterns. This paper suggests that because of the pace of tool development in these two computer capabilities the theme of the central processing unit dominated early, but we are now entering a new, more complex “age of webs.”     

Further routes to psychological constructionism

In this commentary, we do two things. First, we sketch two further routes to psychological constructionism. They are complementary to Lindquist et al.'s meta-analyses and have potential to add new evidence. Second, we look at a challenging kind of case for constructionism, namely, emotional anomalies where there are correlated, and probably relevant, brain anomalies. Psychopaths are our example.     

Measures of spatial memory and routes of learning

Spatial memory was investigated in two experiments by direct methods. Methods included scaling of distances, estimation of bearings, and positioning of objects. Participants learned small-scale configurations under different orders of presentation. In Exp. 1, routes included a shortest path, i.e., a traveling salesman solution, a random sequence, and a path that maximized distances. In Exp. 2, spatial and temporal distances varied independently. It was analyzed whether the different methods yielded the same information. For bearing estimates a new scaling procedure was developed. Computations resulted in two-dimensional Euclidean solutions in close correspondence with the stimulus configuration. In addition, solutions showed an effect of temporal conditions of learning.     

Four Systems Anxiety Questionnaire (FSAQ): a self-report measure of somatic, cognitive, behavioral, and feeling components

This article presents the development of a 60-item self-report known as the Four Systems Anxiety Questionnaire (FSAQ). The FSAQ assesses anxiety on four components: somatic, cognitive, behavioral, and feeling. The FSAQ was given to 218 first-year university students, 54 anxiety patients attending clinical psychology departments, and 14 agoraphobic patients pre- and postpsychological treatment. Results reveal satisfactory reliability and validity levels. In addition, we proved that the FSAQ is sensitive to change following psychological treatment.

Evidence for multiple routes in learning to read

We describe a multiple-route model of reading development in which coarse-grained orthographic processing plays a key role in optimizing access to semantics via whole-word orthographic representations. This forms part of the direct orthographic route that gradually replaces phonological recoding during the initial phases of reading acquisition. The model predicts distinct developmental trajectories for pseudo-homophone and transposed-letter effects - two benchmark phenomena associated with phonological recoding and coarse-grained orthographic processing, respectively. Pseudo-homophone effects should decrease over the first years of reading acquisition, whereas transposed-letter effects should initially increase. These predictions were tested in a lexical decision task with 334 children in grades 1-5, and 29 skilled adult readers. In line with the predictions, we found that the pseudo-homophone effect diminished as reading level increased, whereas the transposed-letter effect first increased and then diminished.     

The strategic control of multiple routes in imitation of actions

The aim of this study was to bring to the surface the strategic use of imitative processes in the context of a 2-route model: (a) direct imitation, used in reproducing new, meaningless actions, and (b) imitation based on stored semantic knowledge of familiar meaningful actions. Three experiments were carried out with healthy participants who reproduced meaningful and meaningless actions within an established time limit. The study investigated 3 factors that could potentially affect the selection of processes used for imitation: (a) the composition of the experimental list (blocked or mixed presentation), (b) the presence-absence of instructions (Experiments 1 and 2), and (c) the relative proportions of the stimuli (Experiment 3). Overall, the results suggest that each of these factors influences the selection of imitative strategies in healthy individuals with temporarily reduced capacities, as happens in the case of brain-damaged patients.     

A cognitive complexity metric applied to cognitive development

Two experiments tested predictions from a theory in which processing load depends on relational complexity (RC), the number of variables related in a single decision. Tasks from six domains (transitivity, hierarchical classification, class inclusion, cardinality, relative-clause sentence comprehension, and hypothesis testing) were administered to children aged 3-8 years. Complexity analyses indicated that the domains entailed ternary relations (three variables). Simpler binary-relation (two variables) items were included for each domain. Thus RC was manipulated with other factors tightly controlled. Results indicated that (i) ternary-relation items were more difficult than comparable binary-relation items, (ii) the RC manipulation was sensitive to age-related changes, (iii) ternary relations were processed at a median age of 5 years, (iv) cross-task correlations were positive, with all tasks loading on a single factor (RC), (v) RC factor scores accounted for 80% (88%) of age-related variance in fluid intelligence (compositionality of sets), (vi) binary- and ternary-relation items formed separate complexity classes, and (vii) the RC approach to defining cognitive complexity is applicable to different content domains.
